CN2352880Y - Electric heater for heating water in thermos bottle - Google Patents

Abstract

The utility model relates to a water heater, belonging to the component of an electric heating thermos bottle. The water heater is composed of a water heating liner, a water inlet pipe, a water outlet pipe, a heating pipe, and a temperature controller. The water inlet pipe is arranged at the bottom of the water heating liner. The water outlet pipe and the temperature controller are arranged on the upper part of the water heating liner, and the heating pipe is inserted from the upper part. The water heater has simple structure and reliable anti-dry burning effect, and the water outlet temperature of the water heater achieves a drinking sanitary requirement.

Description

The electric-heating thermos water boiling device

The utility model belongs to parts of electric-heating thermos, particularly a kind of electric-heating thermos water boiling device.

At present, the structure of electric-heating thermos water boiling device generally adopts the technical scheme of Chinese patent ZL94224560.1, inserts heat-generating pipe in the courage bottom of heating up water, and the top is provided with water inlet, and sidewall is provided with delivery port, wall body device temperature detect switch (TDS).Have simple in structurely, insert from the bottom but weak point is a heat-generating pipe, the high-temperature region of heat-generating pipe is on the upper strata, and water enters sidewall and flows out from the top, cause the heat-generating pipe dry combustion method when lack of water easily, burns heat-generating pipe.In order to address this problem, temperature detect switch (TDS) often device and will control temperature and be reduced to the 90-96 degree at the most close heat-generating pipe place, and the temperature detect switch (TDS) action indicates when water is boiled can be drunk the actual boiling water that comes out also not boiled.

The purpose of this utility model is to solve the deficiency of above-mentioned known technology, and a kind of simple in structure, electric-heating thermos water boiling device that leaving water temperature reaches hygienic requirement and has reliable anti-dry effect is provided.

The purpose of this utility model is achieved in that a kind of electric-heating thermos water boiling device, is made up of the courage of heating up water, water inlet pipe, outlet pipe, heat-generating pipe and temperature controller.Water inlet pipe is located at the bottom of the courage of heating up water, and outlet pipe and temperature controller are located at the top of the courage of heating up water, and heat-generating pipe inserts from top.

The water of the utility model electric-heating thermos water boiling device enters from the water inlet pipe of the courage bottom of heating up water, the outlet pipe on top flows out, and temperature controller is located at the top of the courage of heating up water, the waterborne liter high according to temperature, the heavy under water physical principle that temperature is low has ensured the leaving water temperature of outlet pipe; Again according to the characteristic of heat-generating pipe, the high-temperature region is on the top of heat-generating pipe, low-temperature space is at the root of heat-generating pipe, heat-generating pipe inserts from the courage top of heating up water, the high-temperature region of heat-generating pipe is inserted into the bottom of the courage of heating up water, the low-temperature space of heat-generating pipe places the top of the courage of heating up water, the high-temperature region of heat-generating pipe is still inserted in the water water is boiled when heating up water the firm lack of water of courage, steam conducts heat to temperature detect switch (TDS), cut off the power supply of heat-generating pipe, ensure that heat-generating pipe can dry combustion method, thereby realized that simple in structure, leaving water temperature reaches hygienic requirement, and have the purpose of reliable anti-dry effect.

Below by embodiment the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, a kind of electric-heating thermos water boiling device is made up of the courage 1 of heating up water, water inlet pipe 2, outlet pipe 3, heat-generating pipe 4 and temperature controller 5.Water inlet pipe 2 is arranged on base plate 6 places of the courage 1 of heating up water, and outlet pipe 3 and temperature controller 5 are arranged on top board 7 places of the courage 1 of heating up water, and heat-generating pipe 4 inserts and is installed on the top board 7 from top board 7.

Claims (4)

1, a kind of electric-heating thermos water boiling device is made up of the courage of heating up water, water inlet pipe, outlet pipe, heat-generating pipe and temperature controller, it is characterized in that: in the courage bottom of heating up water water inlet pipe is set, top sets out water pipe, temperature controller and heat-generating pipe.

2, the electric-heating thermos according to claim 1 courage of heating up water is characterized in that: described water inlet pipe is arranged on the base plate of the courage bottom of heating up water.
