Problems solved by technology

However, the heating devices used in these electric heater products currently used all have the problem of being unable to heat the water to a complete boil, because the heating device is closed, and a large amount of water vapor generated during boiling cannot be discharged, that is, it cannot meet the needs. boiling water, therefore, for example, the technology disclosed in patent CN100455145C indicates that it is suitable for heating water to 60-90°C

Embodiment 1

[0020] Such as figure 2 , image 3 As shown, the present invention includes a container body 42, and the bottom of the container body 42 is provided with a thick-film heater 41 composed of a heating resistance element 411. The thick-film heater 41 and the container body 42 are connected and fixed together by a sealing ring, forming a A water container, the periphery of the container body 42 is provided with a water inlet 46 and a water outlet 47, and the heating resistance element 411 is directly screen-printed on the thick film heater 41; It is formed after matching with the container body 42 figure 2 The overall structure of the heating device shown; a plurality of side-by-side partitions 44 are arranged in the deflector 43, and one end of all the partitions 44 is sealed and fixed on the inner surface of the container body 42, and the other end is a free end, and all the partitions 44 are divided into There are two sets of spacers, and the free ends of the two sets of pa...

Embodiment 2

[0023] Such as Figure 4 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the container body 42 and the thick film heater 41 are integral parts, that is, the thick film heater 41 and the container body 42 are made into an integral part, and made into a whole The biggest advantage is that you don't need to consider the problem of water sealing, but the cost may be higher.

[0024] When the present invention is used, as figure 1 As shown, the water inlet 46 communicates with the water storage tank 1 attached with the water pump 2 . During work, after the water pump 2 pumps water to the heating device of the present invention through the pipeline 3, the water flows slowly in the flow channel in the heating device, and the heating resistance element 411 starts heating at this time, and the flowing water is continuously heated until it boils. The water produces a large amount of water vapor, and more steam is generated at the water outlet 47...

Embodiment 3

[0026] Such as Figure 5 , Figure 6 As shown, the difference between this embodiment and Embodiment 2 is that: the water inlet 46 of the heating device is arranged on the container body 42 , and the water outlet 47 is arranged on the thick film heater 41 .

[0027] Of course, it is also conceivable to arrange both the water inlet 46 and the water outlet 47 on the thick film heater.

[0028] The heating device of the invention can be widely used in products such as electric water heaters and electric kettles.

Abstract

The invention discloses electro-heat equipment of an electric heater. The equipment comprises a container body, a thick film heater consisting of heating resistor elements is arranged at the bottom ofthe container body, a fluid director is arranged in the container body, and the container body or the thick film heater is equipped with a water inlet and a water outlet. The equipment is characterized in that the fluid director is equipped with a plurality of separation structures therein to divide an inner chamber of the container body into a plurality of flow passages which are communicated, and a plurality of steam holes are arranged on the flow director. The container body is divided into a plurality of flow passages, water slowly flows through the flow passages after entering from the water inlet, water is rapidly heated under the action of the heating resistor elements and slowly exhausts from the water outlet; and the steam holes are arranged on the flow director, steam which is generated by boiling of the water in the container body can be discharged from the steam holes in time, and the water in the container body can rapidly reach the fully-boiled state, and the water quality is safer.

Description

technical field [0001] The invention relates to a heating device of an electric heater, in particular to a heating device of an electric heater used for rapid heating of flowing water. Background technique [0002] At present, fast electric water heaters and fast boiling kettles are widely welcomed by users because of their fast heating speed, short waiting time for hot water, more energy saving and more convenience. However, the heating devices used in these electric heater products currently used all have the problem of being unable to heat the water to a complete boil, because the heating device is closed, and a large amount of water vapor generated during boiling cannot be discharged, that is, it cannot meet the needs. Therefore, for example, the technology disclosed in patent CN100455145C indicates that it is suitable for heating water to 60-90°C. [0003] Therefore, it is necessary to design a brand-new structure so that the temperature of the water can reach above 90...
