Meat Freezer

TECHNICAL FIELD

The present application relates to the field of refrigeration equipment, in particular to a meat freezer.

BACKGROUND

The meat freezer is a common equipment in life, and is an indispensable fresh-keeping equipment in the catering industry and large supermarkets. The common temperature of the meat freezer for preserving food is about 1 degrees to about 5 degrees. In this environment, most of the bacteria grow slowly. Generally, the freezing temperature is kept at about 18 degrees below zero, at which most of the bacteria are inhibited or killed, thereby having a fresh-keeping effect on the food stored in the refrigerator. If many of the objects are not protected by a low temperature, a large number of bacteria are easily produced, and if the food infected with the bacteria is eaten by mistake, the light person may cause intestinal diseases such as abdominal pain, diarrhea, fever, and the like, and more seriously may cause sepsis.

In the conventional meat freezer, most of the evaporators are arranged at the bottom of the meat freezer, and the evaporators are in a position away from the door, so that a low-temperature environment in the meat freezer is often not ensured due to frequent opening and closing of the door.

Referring to FIG. 1, an embodiment of the present application provides a meat freezer including a machine body 100; a freezing chamber 110 provided on the machine body 100, the freezing chamber 110 having an opening on an upper side thereof; an evaporator 120 disposed in the freezing chamber 100; a compressor 130 and a condenser 140 are provided on the machine body 100, wherein an upper side of the machine body 100 is provided with a door body 101 covering an opening of the freezing chamber 110, the door 101 comprises a first detachable baffle 1011, and an upper portion of the freezing chamber 110 is provided with a shelf 102 adjacent to the first baffle 1011, and the evaporator 120 is installed in the shelf 102.

In contrast to the case where the meat freezer in some cases provides the evaporating device at the bottom of the freezing chamber, the present application provides the evaporator 120 of the meat freezer in a position where the machine body 100 is close to the door body 101, while a detachable baffle is provided above the evaporator 120. Since the evaporator 120 is provided at the upper portion of the freezing chamber 110, on the one hand, in the event of a failure of the evaporator 120, maintenance personnel can conveniently maintain the faulty evaporator 120 and related components; On the other hand, since the cold air generated in the freezing chamber 110 of the meat freezer settles at the bottom of the freezing chamber 110, the evaporator 120 is provided at the upper portion of the machine body 100 close to the door body 101, so that the gas at a higher temperature around the evaporator 120 can be rapidly cooled, and the food placed at the bottom of the freezing chamber 110 can be subjected to a more complete scouring of the cold air, thereby improving the freezing efficiency of the food such as meat.

The refrigeration of the meat freezer is a process of energy conversion. The compressor 130 of the meat freezer is compressed by the low-temperature and low-pressure refrigerant vapor sucked into the evaporator 120. Since the refrigerant liquefies after the temperature in the compressor 130 is lower than the critical point of the refrigerant reaches the required pressure, the refrigerant releases a large amount of heat after liquefaction, which heat is dissipated to the air through the heat sink and the fins. After the liquefied refrigerant dissipates heat, the temperature decreases and enters the evaporator 120 through a capillary tube (not shown) through a buffer. The refrigerant evaporates and absorbs a large amount of heat in the evaporator 120, thereby rapidly reducing the temperature around the evaporator 120, thereby realizing refrigeration of the refrigerator.

The refrigerant dry saturated gas of the meat freezer is compressed by the compressor 130 into superheated refrigerant vapor of high temperature and high pressure, and enters the condenser 140 through the row trachea of the expansion valve piston of the compressor 130. The refrigerant vapor of high temperature and high pressure is condensed into a liquid of low pressure and high pressure in the condenser 140. After this liquid enters the filter of the meat freezer and passes through the capillary tube, the refrigerant vapor of low temperature and low pressure is throttled by equal enthalpy in the capillary tube, and then the refrigerant of low temperature and low pressure boils in the evaporator 120 of equal pressure and absorbs a large amount of heat from the outside to become saturated vapor, so that the refrigeration process of the meat freezer is realized, and finally the refrigerant is sucked into the compressor 130 again for a cooling cycle.

In the present embodiment, the first baffle 1011 is made of foamed plastic or foam rubber, and the foam or the foam rubber is relatively soft, so that the purpose of protecting the evaporator 120 could be achieved. Meanwhile, the foamed plastic is a high-molecular material formed by dispersing a large number of gas micropores in a solid plastic, and has characteristics such as light weight, heat insulation, sound absorption, and shock absorption; The foam rubber is light, soft, elastic, and not easy to transfer heat, and has functions of shock prevention, shock mitigation, heat insulation, sound insulation, and the like. The synthetic rubber also has the characteristics of oil resistance, aging resistance, chemical resistance and the like.

Referring to FIGS. 2 and 5, the door body 101 further comprises a sliding door 1013 in which an outer edge of an upper side of the door body 101 protrudes upwardly to form a flange 1014 for restricting movement of the sliding door 1013 within the door body 101. Further, the door body 101 further comprises a second baffle 1015 positioned above the first baffle 1011, a interstice 1012 exists between the second baffle 1015 and the first baffle 1011, and the sliding door 1013 slides in the interstice 1012 between the second baffle 1015 and the first baffle plate 1011 through the sliding wheel 1016 at the bottom. In addition, the second baffle 1015 provides some protection to the evaporator 120, and the gap may be used to place the article or insulation.

Referring to FIG. 3, in the present embodiment, a filter plate 111 is provided at the bottom of the freezing chamber 110, a through hole 1111 having a uniform distribution is provided in the filter plate 111, a collecting chamber 112 for collecting liquid leaking from the filter plate 111 is further provided at the bottom of the filter plate 111, a drainage port 1121 is provided at one end of the collecting chamber 112, and the drainage port 1121 is used for discharging the condensed liquid filtered from the filter plate 111. When the food to be frozen is contaminated with liquid such as water, the through hole 1111 in the filter plate 111 can conveniently filter out the liquid and discharge the liquid from the collecting chamber 112 below the filter plate 111, thereby avoiding freezing a large amount of ice on the food.

Referring to FIG. 4, in the present embodiment, the machine body 100 further comprises a dissipation chamber 103 located below the freezing chamber 110, the compressor 130 and the condenser 140 are located in the heat dissipating chamber 103, the heat dissipating chamber 103 is provided with air outlets 1031, and the condenser 140 is a mechanical part of a refrigeration system, and belongs to one of heat exchangers, and is capable of converting a gas or a vapor into a liquid, and transferring heat in a conduit to air in the vicinity of the conduit relatively quickly. The operation of the condenser 140 is an exothermic process, so that the temperature of the condenser 140 is high. The refrigerant dry-saturated gas is compressed into superheated refrigerant vapor of high temperature and high pressure by the compressor 130 when passing through the compressor 130, and enters the condenser 140 through the row trachea of the expansion valve piston of the compressor 130. The refrigerant vapor of high temperature and high pressure is condensed into liquid of high pressure and low temperature in the condenser 140. When the compressor 130 compresses the refrigerant, heat generated by the compressor 130 is discharged to the condenser 140 together with a part of the heat generated by the compressor 130, so that the dissipation chamber 103 is not burnt out. The dissipation chamber 103 facilitates heat dissipation of the compressor 130 and the condenser 140, increases the service life, and ensures the working efficiency of the compressor 130 and the condenser 140.

The technical solution provided in the embodiment of the present application has at least the following advantageous effects: Compared with the conventional meat freezer, the evaporator 120 of the meat freezer is arranged at a position close to the door body 101 in the present application, so that a gas with a higher temperature around the evaporator 120 can be rapidly cooled, and since the cold gas generated in the freezing chamber 110 of the meat freezer is settled at the bottom, the food placed at the bottom of the freezing chamber 110 can be subjected to a more complete scouring of the cold gas, thereby improving the freezing efficiency; Next, since the evaporator 120 of the meat freezer is provided at a position close to the door body 101, and a detachable first baffle 1011 is provided above the evaporator 120, when the evaporator 120 is faulty, the first baffle 1011 covered above the freezing chamber 110 can be easily detached, and the evaporator 120 placed in the shelf 102 can be installed, detached and repaired. Therefore, the design of the present invention is simple and reasonable, the freezing efficiency can be improved, the maintenance of the evaporating device is facilitated.
