Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a kettle, and in particular to a fast-cooling electric kettle. Background Art

[0002] The electric kettle uses steam intelligent induction temperature control, which has the functions of automatic power off after the water boils and power off to prevent dry burning. With the needs of life, electric kettles are now developing in the direction of multi-functions, such as leak prevention, scalding prevention, water lock, etc. The working principle of the electric kettle is: the water vapor generated when the water boils is used to deform the bimetallic strip of the steam temperature sensing element, and the deformation is used to push the power switch through the lever principle, so that the electric kettle automatically cuts off the power after the water boils. The power off is not self-reset, so the kettle will not automatically reheat after the power off. The electric kettle has the advantages of fast heating speed, good heat preservation effect, strong filtering function, and many styles.

The electric kettle has novel functions and provides electrolyzed water that conventional electric kettles cannot provide.

[0004] However, in the process of implementing the technical solution in the prior art, the applicant discovered that the technical solution in the prior art had the following technical problems:

[0005] Although there are many styles of electric kettles now, including imported electric kettles that exceed the function of heating drinking water in the existing technology, people cannot drink 100-degree hot water directly because the temperature of hot water reaches 100 degrees. Therefore, if you want to drink water, you have to wait for the temperature of the boiled water to drop before drinking it. It takes a long time for the temperature of the boiled water to drop, resulting in the inability to drink water in time. In order to solve the problem of not being able to drink water in time, some water dispensers mix cold water to cool down the hot water. However, in the minds of many users, mixing cold and hot water is not easy to accept, which affects the experience of drinking water. Summary of the invention

[0027] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] The electric kettle uses steam intelligent induction temperature control, which has the function of automatic power off after the water boils and power off to prevent dry burning. As people's living standards improve, people's requirements for drinking water are getting higher and higher. From the perspective of drinking water safety, drinking boiled water is more hygienic. However, the temperature of boiled water is high and cannot be drunk in time. If you wait for the water to cool before drinking it, it will take a certain amount of time, which will affect the experience. If cold water is added to the boiled water to cool it down, in the concept of some southern regions, it belongs to "yin and yang" water, which is not conducive to the drinking experience.

[0029] The technical solution of the embodiment of the present application solves the problems of long cooling time, inconvenient drinking water and poor user experience in the prior art by providing an electric kettle with fast cooling. The heat dissipation part 300 distributed on the outer wall of the kettle body 100 achieves the beneficial effects of accelerating the cooling of boiling water, facilitating drinking water and improving user experience.

[0030] The overall idea of ​​the implementation scheme of the present invention to solve the above technical problems is as follows:

[0031] A fast cooling electric kettle, comprising a kettle body 100, a base 200, a heat dissipation part 300 and a heat dissipation fluid driving part 400, wherein the heat dissipation part 300 is at least distributed on the outer wall of the kettle body 100, the heat dissipation part 300 has a heat dissipation channel with a preset structure; the heat dissipation fluid driving part 400 is connected to the inlet of the heat dissipation channel, and a series of technical means. The fluid passes through the heat dissipation fluid driving part 400 at a speed higher than that of still air and leaves at the outlet 310 of the heat dissipation channel to take away the heat of the kettle body 100.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] A fast cooling electric kettle, such as Figure 1-2 As shown, it includes a kettle body 100, a base 200, a heat dissipation part 300 and a heat dissipation fluid driving part 400; the heat dissipation part 300 is distributed at least on the outer wall of the kettle body 100, and the heat dissipation part 300 has a heat dissipation channel with a preset structure; the heat dissipation fluid driving part 400 is connected to the inlet of the heat dissipation channel, and the end of the heat dissipation channel away from the base 200 is the outlet 310; the fluid passes through the heat dissipation channel at a speed higher than that of still air through the heat dissipation fluid driving part 400 and takes away the heat of the kettle body 100.

[0034] When the drinking water boils, the heat dissipation fluid driving component 400 starts, and air enters from the entrance of the heat dissipation channel, quickly passes through the heat dissipation channel and takes away the heat of the kettle body 100. When the temperature of the kettle body 100 drops, the heat of the hot water in the kettle body 100 is also dissipated, thereby achieving a cooling effect.

[0035] If the heat dissipation fluid driving member 400 is set on the base 200, although it can also play a role in heat dissipation, when in use, it is necessary to align the inlet of the heat dissipation channel of the kettle body 100 with the heat dissipation fluid driving member 400. When using a hot water kettle, a general user often casually places the kettle body 100 on the base 200 and presses a button to start heating, without deliberately aligning the inlet of the heat dissipation channel of the kettle body 100 with the heat dissipation fluid driving member 400. When heating, the kettle body 100 cannot be rotated at will, and rotating the kettle body 100 at will will result in the inability to align the inlet of the heat dissipation channel with the heat dissipation fluid driving member 400, which makes it inconvenient to use and affects the user experience.

[0036] In order to further improve the convenience of use, the heat dissipation fluid driving member 400 is arranged on the lower side wall of the kettle body 100, and the bottom of the kettle body 100 matches the base 200 and can rotate along the center point of the base 200. When in use, the kettle body 100 can be placed horizontally on the base 200 at any angle. Even if the kettle body 100 is rotated at will during heating, it will not affect the alignment of the heat dissipation fluid driving member 400 and the entrance of the heat dissipation channel. Improve the convenience and experience of use.

[0037] The heat dissipation channel can be set up in a variety of different preset structures according to actual conditions, for example:

[0038] The preset structure is a vertical flow channel (refer to Figure 1 )、Spiral channel (refer to Figure 3 ).

[0039] The larger the contact area, the longer the path through which the fluid flows, and the more complete the heat dissipation. In a preferred embodiment, the preset structure is an S-shaped flow channel (spiral flow channel).

[0040] Among them, the spiral flow channel is a unidirectional spiral flow channel (refer to Figure 4 ) or bidirectional spiral flow channel (refer to Figure 5 ).

[0041] The use of double helix flow channels can increase the efficiency of heat conduction to increase the speed of cooling.

[0042] The heat dissipation fluid driving member 400 is at least one electric fan, and an electric fan can be added in actual use. At the same time, in order to prevent the kettle from being scalded, a heat insulating material can be provided at one end of the heat dissipation channel away from the kettle body 100.

[0043] In order to save energy and avoid unnecessary operation of the heat dissipation fluid driving component 400, a temperature sensor is further provided inside the kettle body 100. The temperature sensor is communicated with the heat dissipation fluid driving component 400, and the opening and closing of the heat dissipation fluid driving component 400 is determined according to the value of the temperature sensor.

[0044] Overheating of the base 200 will affect the service life of the electric kettle. The heat dissipation channel preferably passes through the bottom and side walls of the kettle body 100 to take away the heat from the bottom and side walls of the kettle body 100, thereby preventing the electric kettle from overheating.

[0045] In a preferred embodiment, the heat dissipation fluid driving member 400 has a driving mode including a battery driving mode and an electric driving mode. After the base 200 is powered off, the operation of the electric fan can be maintained by battery driving.

[0046] A fan is used as the heat dissipation fluid driving member 400, referring to Figure 6 The angle of the fan can be parallel, vertical or at a certain angle to the ground. In addition, the fan can also be parallel to the outer wall of the kettle body 100. No matter in which direction the kettle body 100 is placed on the base 200, the normal operation of the heat dissipation fluid driving member 400 is not affected.

[0047] Although the cooling of hot water can be accelerated by blowing air on the side wall of the kettle body 100 of the electric water kettle to dissipate heat, the way of cooling hot water is too single. In order to further improve the efficiency of hot water cooling, an automatic lid opening device is provided, and the automatic lid opening device is communicatively connected with the temperature sensor; wherein, when the sensed temperature reaches a preset temperature, the automatic lid opening device is started, and the lid located at the end of the kettle body 100 away from the base 200 is opened to a certain extent, and heat dissipation is achieved by blowing air and opening the lid in a two-pronged manner.

[0048] In order to enhance the user experience, in one embodiment, a stirring wheel is provided in the kettle body 100, which, combined with the automatic lid opening and the heat dissipation fluid driving component 400, can accelerate the heat loss of hot water, thereby achieving a rapid cooling effect.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
