Abstract
The utility model relates to a safe electric heating water heater. The safe electric heating water heater comprises an outer shell, an inner liner, a bracket, a heating ring, a line control board, etc. The safe electric heating water heater is characterized in that the end part position of the heating ring is provided with a hole, and an overtemperature protection device is arranged in the hole. Due to the fact that the overtemperature protection device is arranged on the end part of the heating ring by the safe electric heating water heater, the overtemperature protection device can duly and directly induce the temperature of a heating pipe, and the working state of the safe electric heating water heater can be effectively and duly controlled by a circuit, and the overheating and the burning out of the heating pipe and a water liner are avoided. Thereby, the use safety of the safe electric heating water heater can be fully ensured, the service life of the safe electric heating water heater is effectively prolonged; meanwhile, the safe electric heating water heater has simple structure and artful design.
Description
The utility model relates to a kind of electric water boiler, belongs to the improvement of household electrical appliance.
Existing electric water boiler, its attemperating unit generally all is arranged on the bottom of heating ring, the temperature that temperature controller is responded to is the indirect temperature of conducting heat by air or base plate, not the temperature that directly induction heating encircles, in use, often exist and forget the phenomenon that adds water and press button to boil water by mistake because of carelessness, because it is anhydrous in the water courage, the heat-generating pipe environment temperature rises rapidly, takes measures to make heat-generating pipe and water courage to burn and explodes as untimely, severe patient even cause serious consequences such as fire.
The purpose of this utility model provides a kind of safety electric boiler that has the effect of high sensitivity overtemperature prote, can promptly and accurately directly respond to heating ring temperature.
The utility model comprises shell, inner bag, support, heating ring, circuit control panel etc., and its characteristics be to generate heat end position of ring has the hole, is provided with overtemperature protection device in this hole.
The utility model is owing to be provided with overtemperature protection device in heating ring end; overtemperature protection device can in time directly be sensed the temperature of heat-generating pipe; make circuit can effectively in time control its duty; avoid heat-generating pipe and water courage overheated or burn, thereby can fully guarantee the safety of using and effectively prolong its service life.Simultaneously the utility model simple in structure, be skillfully constructed.
Describe basic structure of the present utility model and operation principle in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1; the utility model comprises shell (1); inner bag (2); support (3); heating ring (4); circuit control panel etc.; wherein heating ring (4) is the pili annulati heat pipe; the end position of heating ring (4) has the hole that communicates with heat-generating pipe; the shape in hole can be square circular or square and circular assembly; in this hole, be provided with overtemperature protection device (5); can in time sense the temperature of heating ring (4) to guarantee overtemperature protection device (5); overtemperature protection device (5) then adopts reducible high sensitivity low profile thermal protector; its operating temperature is 120 ℃ ± 5 ℃; for avoiding scattering and disappearing of heat in the hole; fully assurance overtemperature protection device (5) can accurately be sensed the temperature of heating ring (4); be provided with sealing-plug (6) in the aperture; overtemperature protection device (5) places in the hole; sealing-plug (6) then seals up the aperture; two terminal pins of overtemperature protection device (5) thermal protector pass sealing-plug (6) and are connected with the circuit control panel like this when the lack of water heating occurring and cause dry combustion method; the temperature of heating ring (4) rises rapidly; when rising to the operating temperature that set point of temperature is a thermal protector (120 ℃ ± 5 ℃); overtemperature protection device in the hole (5) tripping at once; whole circuit is stopped power supply, thereby avoid heat-generating pipe and water courage overheated or burn.Adopt reducible thermal protector to make overtemperature protection device simultaneously, when heating ring temperature was reduced to certain numerical value (being generally normal temperature), thermal protector was from the horizontal reset conducting, in the water courage, add entry after, but it is to boil water to restart the button normal heating.
Claims (3)
1, a kind of safety electric boiler, it comprises shell, inner bag, support, heating ring, circuit control panel etc., the end position that encircles that it is characterized in that generating heat has the hole, is provided with overtemperature protection device in this hole.
2,, it is characterized in that two pins that above-mentioned aperture is provided with the sealing-plug overtemperature protection device passes sealing-plug and is connected with the circuit control panel according to the described safety electric boiler of claim 1.
3,, it is characterized in that above-mentioned overtemperature protection device is reducible high sensitivity low profile thermal protector according to the described safety electric boiler of claim 1.
