Abstract

The invention discloses an adjustable immersion heater, which belongs to the field of household appliances. The adjustable immersion heater comprises a bottle stopper, and a section of heating-conducting tube passes through the bottle stopper and extends downwards; the heating-conducting tube is divided into an upper heating-conducting tube and a lower heating-conducting tube, a port of the upper heating-conducting tube or the lower heating-conducting tube is fixedly connected with a section of heat insulator, and a close sliding fit can be formed among the upper heating-conducting tube, the lower heating-conducting tube and the heat insulator; and the lower thermal-conducting tube is internally provided with an electric heating body, and the electric heating body is electrically connected with a plug cord (passing through the bottle stopper) by a lead arranged in the thermal-conducting tube. By using the adjustable immersion heater, the water heating efficiency can be guaranteed, and the immersion heater can be prevented from being burnt out when used for heating a small amount of water.

Description

A kind of adjustable immersion heater

Technical field

The present invention relates to a kind of household electrical appliance, especially, is a kind of immersion heater that is used to heat up water, and comprises bottle stopper, electric heating element, heat pipe.

Background technology

Immersion heater is a kind of household electrical appliance commonly used, is used to boil water, and when heating up water, only needs immersion heater is inserted in the thermos, and energized can because it is convenient and practical, therefore obtain using widely to thermos inner cold water Fast Heating.

For common immersion heater, comprise bottle stopper and pass bottle stopper and to the heat pipe that extends below, heat pipe inside is provided with calandria; After the immersion heater energising; The inner calandria of heat pipe generates heat fast, and with the heat transferred heat pipe, passes to water body by heat pipe again; Because traditional immersion heater heat pipe is one up and down, therefore, when calandria heats; Whole heat pipe will generate heat together, if the user only need burn a spot of boiling water, water body fills with in the thermos; Then the heat pipe upper semisection is because heat can't in time leave as easy as rolling off a log burning out; And if adopt non-Heat Conduction Material to process the upper semisection of heat pipe, then when burning full bottle boiling water, the efficiency of heating surface is lower again, therefore, this problem is perplexing the immersion heater manufacturer for a long time.

Summary of the invention

In order to address the above problem, the object of the present invention is to provide a kind of adjustable immersion heater, this adjustable immersion heater both can guarantee the efficient of heating up water, and can prevent that again immersion heater is burnt out when burning a small amount of boiling water.

The technical solution adopted for the present invention to solve the technical problems is: this adjustable immersion heater comprises bottle stopper, and one section heat pipe passes said bottle stopper and to extending below; Said heat pipe is divided into heat pipe and following heat pipe, and said port of going up heat pipe or following heat pipe is fixedly connected one section heat guard, can form between said upward heat pipe, following heat pipe, the heat guard closely to be slidingly matched; Said heat pipe inside down is provided with electric heating element, and this electric heating element is electrically connected with the plug cord that passes said bottle stopper through being located at the inner lead of said heat pipe.

As preferably, said heat pipe down comprises one section helix tube, to increase area of dissipation.

As preferably, the said heat pipe of going up is made up of copper pipe or aluminum pipe with following heat pipe, has good heat-conducting.

As preferably, the said external diameter of going up heat pipe equals heat pipe internal diameter down, and said heat guard plug is gone up in the heat pipe in said, and the external diameter of this heat guard equates with last heat pipe; Also be provided with one annular protrusion on the said heat guard, the said inside, port of heat pipe down then is provided with the twice annular protrusion, forms position-limiting action with this; This optimal way is convenient to processing and manufacturing.

Beneficial effect of the present invention is: when adopting this adjustable immersion heater to heat up water; For the boiling water that burns full bottle; Only need said heat pipe and the following heat pipe slide in opposition of going up; Both are in contact with one another, then descend the electric heating element in the heat pipe will be heat pipe and the heating of last heat pipe down simultaneously, thereby obtain maximum heating efficient; For the situation that only needs to burn a small amount of boiling water, then, make between the two and isolate by said heat guard with said heat pipe and the following heat pipe dorsal glide of going up, then, can't burn out heat pipe only by heat pipe heating down; This adjustable immersion heater both can guarantee the efficient of heating up water, and can prevent that again immersion heater is burnt out when burning a small amount of boiling water.

Description of drawings

Fig. 1 is the state diagram of embodiment of this adjustable immersion heater when burning a small amount of boiling water;

Fig. 2 is the state diagram of Fig. 1 embodiment when burning a large amount of boiling water.

Among the figure: 1, bottle stopper; 21, go up heat pipe; 22, following heat pipe; 220, helix tube; 23, heat guard; 3, plug cord.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

In the embodiment shown in fig. 1, this adjustable immersion heater comprises that 1, one section heat pipe of bottle stopper passes said bottle stopper 1 and to extending below; Said heat pipe is divided into heat pipe 21 and following heat pipe 22; The said external diameter of going up heat pipe 21 equals heat pipe 22 internal diameters down, and one section heat guard 23 is filled in said and gone up in the heat pipe 21, is fixedly connected with last heat pipe 21; The external diameter of this heat guard 23 equates with last heat pipe 21; So, saidly go up heat pipe 21, form between heat pipe 22, the heat guard 23 and closely be slidingly matched down, and also be provided with one annular protrusion on the said heat guard 23; The said inside, port of heat pipe 22 down then is provided with the twice annular protrusion, forms position-limiting action with this;

Said heat pipe 22 inside down are provided with electric heating element, and this electric heating element is electrically connected with the plug cord 3 that passes said bottle stopper 1 through being located at the inner lead of said heat pipe.

Said heat pipe 22 down comprises one section helix tube 220, to increase area of dissipation.

Above-mentioned adjustable immersion heater, the said heat pipe 21 of going up is made up of copper pipe or aluminum pipe with following heat pipe 22, has good heat-conducting.

When adopting above-mentioned adjustable immersion heater to heat up water; For the boiling water that burns full bottle; Only need both to be in contact with one another said heat pipe 21 and following heat pipe 22 slide in opposition of going up, its state is as shown in Figure 1; Then descend the electric heating element in the heat pipe 22 will be

heat pipe

22 and 21 heating of last heat pipe down simultaneously, thereby obtain maximum heating efficient; For the situation that only needs to burn a small amount of boiling water, then with said heat pipe 21 and following heat pipe 22 dorsal glide of going up, make between the two and isolate by said heat guard 23, its state is as shown in Figure 2, then only by heat pipe 22 heatings down, can't burn out heat pipe; This adjustable immersion heater both can guarantee the efficient of heating up water, and can prevent that again immersion heater is burnt out when burning a small amount of boiling water.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
