Description.
The Waste Disposal Control System (W.D.C.S. (8)) that when connected to a new or existing domestic or commercial Kitchen Waste Disposal (6) can control the water and electric power supply.
The purpose.
To avoid Waste Disposals (6) blades from blocking, jamming, overloading and failing, eliminating operator error.
Background of the invention.
Waste Disposal (6)s are designed to dispose of soft waste from the kitchen, by emulsifying the said waste with rotating blades located inside the unit. The unit requires water to flush the emulsified waste down the outlet. As emulsification and flushing occurs
simultaneously, it is critical that water is supplied to the motor being energised.
Furthermore it is important that the water supply (4) is positioned directly over the mouth of the inlet of the unit to attain the maximum water flow. Should water not be supplied to the motor being energised, it is highly probable that the unit will block or jam and fail to work. Our research has found that blockages occur quite frequently as a result the manufacturer has installed a reset switch which is located on the bottom of the unit which is located under the sink. Once the reset button has been depressed and water is directed into the unit, as mentioned, it is possible to re-started the unit. In most instances resetting the unit will clear the unit. However, in some instances the unit will remain blocked. In such cases the unit will have to be replaced or at least returned to the supplier for repair, as the unit is sealed and not easily disassembled.
As the units can be used in both commercial and domestic environments, it is possible that they could be operated by adults and children alike and hence operator error. If the person preparing the meal is busy or the child is not aware of the need for water, it is all too common for the unit to be switched on without a water supply (4).
If there was a system that automatically supplied water directly to the Waste Disposal (6) simultaneously or prior to the unit turning on, this would prevent this potential problem. Our initial research of the market indicated there was no such unit available.
For such a system to work it would require a separate inlet for water supply (4) to the unit positioned above the blades. We discovered that there was such an inlet which was used to connect the waste from the Dishwasher, which is rarely used. The W.D.C.S. (8) unit could be connected to the Dishwasher Drain (10) outlet. To assist the installation of the W.D.C.S. (8) the manufacturer of Waste Disposal (6) details in there manuals how to remove the said plastic plug, to enable the inlet to be used.
Further investigation into how this could be installed with "off the self products proved expensive and would require both Electrical and Plumbing trades, adding further cost to the installation. This approach would be a cumbersome and would have few features with limited liability, not being solid state control.
Therefore the requirement was to design a unit that would be easily installed without the need for either an Electrician or Plumber. Such a unit would have to be installed easily without any technical knowledge or expertise. This would require an all-in-one unit to be designed that would easily connect to the water system. It must also be able to be plugged in electrically directly into the existing power supply for the Waste Disposal (6). As mentioned the Waste Disposal (6)s should be capable of being installed in both commercial and domestic environments therefore must be capable electrically, of both single and three phase operation, in 240 volt, 50 Hz and 110 volt, 60 Hz power supply.
Description.
The W.D.C.S. (8) unit (Model SAVC) can connect to most food Waste Disposal (6). The W.D.C.S. (8) unit controls both the Electric Motor of the Waste Disposal (6) and the water supply (2) (5) via a low voltage Solenoid (7). When the unit is switched on (13) the W.D.C.S. (8) can immediately supply water to the Waste Disposal (6) via the dishwasher inlet (10). After a predetermined time the electric motor of the Waste Disposal (6) starts. By supplying water prior to the Waste Disposal (6) being energised prevents soft waste material from jamming and possible failure of the unit. The unit can also operate with both single phase and three phase motors with either 240 volt 50 cycles or 110 volt 60 cycles. The W.D.C.S (8) is fitted with a safety cut out, if the unit is left on for more than a predetermined period, this safety cut out which can be deleted or modified at the point of manufacture. The W.D.C.S. (8) unit connects to the Electrical wall socket (13) possibly previously used for the Waste Disposal (6) connection. The Waste Disposal (6) electrical plug connects to output of the W.D.C.S. (8) at (14) the output (15) connects to the Waste Disposal in series; the water input is connected to the mains water supply (4) via a tee connector (3).
Statement of the Invention.
Technical Features:
1) When the switch for the Waste Disposal (6) is activated a 24 volt
Solenoid (7) switches the water on to the Waste Disposal (6)
automatically.
2) After a predetermined time the motor for the Waste Disposal (6) turns on.
3) This time delay can be modified from zero to 5 minutes or more.
4) The input and output of the water supply (2) (5) will fit any domestic water
supply (4).
5) The unit can operate with 240 volt or 110 voltage supply.
6) The PCB (FIG 1/2/3/4/5 ) can be modified to operate with single or three
phase motors.
7) The electrical input and outputs (14) (15) are fitted on the outside of the unit, this enables, with the addition of a standard three pin power cable, the unit can be connected without any additional electrical work or power points.
8) The W.D.C.S. (8) has been designed so as installation can be completed without the need for Plumbing or Electrical Tradesmen.
9) Can be set to automatically switch off the motor from one second to
any predetermined period of time.
10) Indication lights show the motor and water supply (4) in operation.
11) The motor can be turned off and then on again at any stage whilst the
water is running.
12) The water control can be by-passed by a separate switch to operate
independently of the motor.
13) The water supply (4) can be set to run on and off at preset periods during
the operation of the Waste Disposal (6).
14) The flow rate of the water can be adjusted. Detailed Description of the Invention.
W.D.C.S. (8) can be housed in a single and separate Box. A low AC or DC voltage Solenoid (7) that switches the water supply (4) on and off which is mounted and sealed on the outside face of the Box thereby complying international electrical standards. The value control shaft of the Solenoid (7) fits through the face of the main housing Box. The low voltage electrical coil of the Solenoid (7) is fitted to the value control shaft on the inside of the Box and connected to PCB (FIG 1/2/3/4/5 ). The power supply is via two standard 240v or 110 v three pin plugs mounted on the face of the Box adjacent to the Solenoid (7). The male electrical socket (14) connects to the mains power supply which the Waste Disposal (6) was previously connected and the female electrical socket connects to the Waste Disposal (6). The PCB (FIG 1/2/3/4/5 ) is mounted in the Box.
Water supply (4) input to the Solenoid (7) is connected to the mains water supply (4) via a standard tee fitting (3) inserted to the water supply (4) of the Kitchen Tap (1) or any other convenient location.
The output of the of the Solenoid (7) connects via a low pressure flexible hose (9) to the inlet of the Waste Disposal (6) secured by a jubilee clip type of fixing (16). The inlet of the Waste Disposal (6) is normally designated as the Dish Washer Drain (10). If the Dishwasher Drain is already in use for the Dish Washer Drain then a low pressure tee connection will have to be inserted into the Dish Washer Drain pipe immediately prior to the connection to the Waste Disposal (6).
If the Dishwasher inlet is not connected, the Dishwasher Drain plug in the main wall of the Waste Disposal (6) (10) will have to be removed. It is our experience that the Dishwasher drain inlet is rally used.
