CN2234746Y - Temperature control for thermos bottle and boiled water drinker - Google Patents

Abstract

The utility model relates to a temperature control for a thermos bottle and a boiled water drinker. A plastic die sleeve with high temperature resistance and favorable dimension stability is sheathed on the sensing section of the temperature controller, which causes the sensing section between the plastic die sleeve and the temperature controller to keep a suitable interval. When the calorie needs to convey from the cartridge heater to the sensing section of the temperature controller, utilizing the plastic material and air as an undesirable heat conduction element, the thermal conductivity is lowered, and extending the efficacy of boiling time.

Description

The prolongation boiling device of thermos bottle, the machine of beginning to drink

The utility model belongs to daily living article, the prolongation boiling device of a kind of thermos bottle of more specifically saying so, the machine of beginning to drink.

The present commercially available thermos bottle or the machine of beginning to drink, a kind of is all to make with stainless steel in the detecting part site surface of temperature controller, and directly contact with desire sensing subject matter, so that suitably apace sensed temperature is promptly reacted to temperature controller, temperature controller is made change action according to the operating temperature (being generally 96 ± 3 ℃) of its setting again, but it is constant that the boiling point of this kind control boiling apparatus Chang Yinshui continues at certain environment, and the temperature controller of control boiling point truly has certain error.Another kind is the circuit arrangement of boiling again that utilizes the electronic loop formula, prolong its boiling time and avoid first kind deficiency, but often because of the moist electronic circuit device operate as normal that influences of the high temperature of product own, and forming the loop needs various precise electronic spare and accessory parts more, its price is higher, the assembling trouble, raises the cost relatively.

The purpose of this utility model will provide a kind of undesirable heat transport element exactly in thermos bottle, the machine of beginning to drink, and reaches the effect that prolongs boiling time to reduce its pyroconductivity.

The prolongation boiling device of this thermos bottle, the machine of beginning to drink, be above the water level index line of this cartridge heater, the sheathed plastic cement die sleeve in the sensing position, front side of temperature controller, the front end face at the back of the body end face of this plastic cement die sleeve and the sensing position of this temperature controller predetermined clearance space of being separated by, make the sensing position be delayed a period of time and just sense the operating temperature that sets, thereby delay the switch that escape cuts off its rear side.

The distinguishing feature of this device is: in general material, under the same temperature conditions with regard to pyroconductivity, metal＞nonmetal (as plastic cement, glass, timber etc.)＞air, temperature with the thermos bottle inner core reduces its pyroconductivity by plastic cement die sleeve and air for this reason, make the temperature on temperature＞temperature controller surface at the temperature＞plastic cement die sleeve back side in the cartridge heater at one time, but because the boiling point of water is 100 ℃, when the water in the cartridge heater is heated to boiling point by 25 ℃ of room temperatures, again because of the sensitivity of the coefficient of heat conduction to temperature, after temperature exceeds room temperature, its value can Yin Wendu rising and decrescence, make that temperature controller surface institute sensed temperature is not 100 ℃, but the temperature difference of certain degree is arranged, this moment the water in the cartridge heater because of the temperature controller sensing not the disconnected operating temperature (96 ± 3 ℃) of Dutch continue to be heated, so heating (approximate number minute) after after a while, because the temperature during this period of time in the cartridge heater remains on 100 ℃ of boiling points, heat continues to conduct to the temperature controller surface via plastic cement die sleeve and air dielectric, and when the temperature controller surface arrives switch operating temperature (96 ± 3 ℃), just heating power supply is switched to insulation and set.

Below in conjunction with accompanying drawing the utility model is further described

This thermos bottle, the begin to drink prolongation boiling device of machine, be at existing thermos bottle, the water level of cartridge heater (2) of machine of beginning to drink refers to line (22) top, on the sensing position, front side (32) of last temperature controller (3), sheathed one deck just makes the back of the body end face (51) of this plastic cement die sleeve (5) to plastic cement die sleeve (5) (adopting material high temperature resistant and thermosetting plastic cement power the best that the size security is good) that should detecting part position (32), with the front end face (321) at the sensing position (32) of temperature controller on this (3) the predetermined clearance space (30) of being separated by, make this sensing position (32) be delayed a period of time and just sense the operating temperature that sets, and delay the switch (31) that escape cuts off its rear side, thereby also postpone control electric heater device (4) and stop heating, sustainable relatively heating a period of time, reach the purpose that prolongs boiling time, and then boiling water can be heated cmpletely boil.

Claims (1)

1, the prolongation of a kind of thermos bottle, the machine of beginning to drink boiling device, it is characterized in that it is above the water level index line of cartridge heater, the sensing position, front side of last temperature controller, the plastic cement die sleeve at the corresponding sensing of sheathed one deck position, the front end face at the back of the body end face of this plastic cement die sleeve and the sensing position of the temperature controller clearance space of being scheduled to of being separated by.
