Title:
A TEMPERATURE-CONTROL SWITCH, AN ELECTRICAL-HEATING JUG AND A WIRELESS ELECTRICAL-HEATING JUG
Document Type and Number:
WIPO Patent Application WO/2005/055784
Kind Code:
A1
Abstract:
The invention relates to an electrical-heating technology for liquid, to a temperature-control switch, an electrical-heating jug, and a wireless electrical-heating jug. The problems described below may be solved. Since the water in a jug has been boiled or baked, thereby cooling or reheating the jug, and after the water is baked, resulting in fire, and since sound-alarm occurs for long time after the water is boiled, thereby forming noise. The temperature-control switch includes a body (1), primary electrical-connecting ends (2), (3), a movable contact piece (4), a static contact piece (5) and a first temperature sensing control device (7), there are a second temperature sensing bimetal piece (8) and a secondary electricalconnecting end (9) on the body (1), a secondary movable contact piece (10) is provided on the secondary electrical-connecting end (9), a secondary push rod (11) is provided between the second temperature sensing bimetal piece (8) and the secondary movable contact piece (10), after the first temperature sensing control device (7) is actuated due to being heated, when the second temperature sensing bimetal piece (8) is upwarped due to being heated, the secondary push rod (11) may be actuated to push the secondary movable contact piece (10), moving to the movable contact piece (4) and contacting with it. A vapor sensing generator (22) is added to the electrical-heating jug and the wireless electrical-heating jug by using the said temperature-control switch.
