Description

Technical Field

[0001] The present application relates to the technical field of household electrical appliances, and in particular to a kettle. Background Art

[0002] In daily life, people are used to drinking boiled water, so electric kettles are almost essential tools for life. Regarding drinking water, we often face a problem. After the water is boiled, its temperature needs to be lowered before drinking. However, the efficiency of heat exchange between the kettle and the air by simple heat dissipation is very low, that is, it takes a long time for the water temperature to drop to a suitable drinking temperature. This greatly affects our daily life and wastes time. Most electric kettles are equipped with heat insulation covers on the surface, which only consider heat preservation but do not have cooling function. Compared with heat preservation, rapid cooling function is also necessary. For example, warm water is needed to feed medicine to children and to brew beverages such as protein powder.

[0003] At present, some electric kettles have a coolant flow channel between the inner tank and the outer shell, and use the coolant to cool the liquid in the inner tank, so that the electric kettle has a cooling function. However, the heat absorbed by the coolant will also be transferred to the outer shell, causing the outer shell temperature to be high, which may scald the user. Utility Model Content

[0004] Based on this, it is necessary to provide a hot water kettle to solve the above problems in the existing hot water kettle.

[0005] The hot water kettle provided in the present application comprises a housing component, a heating component and an air supply device, wherein:

[0006] The housing assembly comprises a kettle body and an air duct housing, wherein a water storage cavity and a water outlet connected to the water storage cavity are provided in the kettle body, and the air duct housing is connected to the kettle body, and an air guide channel and a first through hole are provided in the air duct housing, wherein the first through hole, the air guide channel and the water storage cavity are connected in sequence;

[0007] The heating component is arranged on the kettle body or the air duct housing to heat the water storage cavity;

[0008] The air supply device is arranged on the air duct housing, and is used for sucking airflow from the first through hole and guiding the airflow into the water storage cavity.

[0009] The kettle disclosed in the present application has a kettle body connected to an air duct shell, and a user can hold the air duct shell to move the kettle body or pour water, wherein a water storage chamber is provided in the kettle body, and an air duct shell is provided with an air guide channel connected to the water storage chamber, and an air supply device is provided on the air duct shell. The kettle can be started automatically or manually. The air supply device is started, for example, after the water in the water storage chamber is heated and boiled, the air supply device is automatically started, and the air supply device sucks airflow from the first through hole and guides the airflow into the water storage chamber through the air guide channel to quickly cool down the liquid, thereby shortening the cooling time of the liquid and meeting the user's need to drink water of suitable temperature in time.

[0010] In one embodiment, the air duct housing includes a handle and a base, the base is connected to the handle, the air guide channel is formed in the handle, the first through hole and the installation cavity are formed on the base, the first through hole, the installation cavity and the air guide channel are connected in sequence, and the air supply device is installed in the installation cavity.

[0011] The kettle in the above embodiment further defines that an air guide channel and an installation cavity are respectively provided on the handle and the base, and the installation cavity is used to install an air supply device, and the air supply device transmits the generated airflow to the water storage cavity through the air guide channel. By opening the air guide channel in the handle, it will neither affect the user's hand-held movement nor increase the overall volume of the kettle, so that the overall design of the kettle is reasonable.

[0012] In one embodiment, a first opening and a second opening are provided on the air guiding channel, the air guiding channel is connected with the installation cavity through the first opening, the air guiding channel is connected with the water storage cavity through the second opening, and the second opening is located above the kettle body.

[0013] The hot water kettle in the above embodiment further defines a second opening in the air guide channel away from one end of the mounting cavity, which is distributed above the kettle body, so that the airflow generated by the air supply device blows from top to bottom through the air guide channel on the top of the kettle body to cool the liquid surface in the water storage cavity. At the same time, arranging the second opening above the kettle body can not only avoid the possibility of backflow of the air guide shell due to the horizontal height of the second opening on the kettle body being too low, but also avoid the problem of too little water in the kettle body due to the horizontal height of the second opening on the kettle body being too low.

[0014] In one of the embodiments, the kettle body includes a kettle body and a top cover, wherein the top cover is disposed on the kettle body, and the top cover is rotatably connected to an end of the handle close to the second opening.

[0015] The hot water kettle in the above embodiment further defines that the handle is located at the second opening and rotates with the top cover, and the top cover can rotate relative to the handle and form at least a first position and a second position. When the top cover is in the first position, the top cover is in an open state relative to the kettle body, so that the heat in the kettle body can be better contacted with the outside world. When the top cover is in the second position, the top cover is in a closed state relative to the kettle body. In addition, by rotating the top cover on the handle, whether the top cover is in the first position or the second position, it will not affect the effect of the air guide channel supplying air to the water storage cavity.

[0016] In one of the embodiments, the kettle body and the air duct housing are detachably connected.

[0017] In one of the embodiments, the air duct housing is provided with a first air filter at the first through hole.

[0018] The kettle in the above embodiment further defines that an air filter is provided at the first through hole on the air duct shell, and the air filter can filter the air before entering the fan assembly, thereby delivering clean cold air to the water storage chamber to prevent the liquid from being contaminated.

[0019] In one of the embodiments, a second air filter is provided in the air guide channel.

[0020] In one embodiment, the first air filter is detachably connected to the air duct housing.

[0021] In one of the embodiments, a one-way valve is provided in the air guiding channel, and the air guiding channel is selectively connected to the water storage chamber through the one-way valve.

[0022] The kettle in the above embodiment further defines a one-way valve in the air guide channel, which can control the connection or cutoff of the air guide channel with the water storage chamber. For example, when the liquid in the water storage chamber is heated, the one-way valve is closed, and the connection between the air guide channel and the water storage chamber is cut off, so as to prevent the steam from the liquid during the heating process from entering the installation chamber through the air guide channel and affecting the heating component and the air supply device. When the liquid is heated, it is necessary to cool the liquid quickly. At this time, the one-way valve is opened, the air guide channel is connected to the water storage chamber, and the cold air generated by the air supply device enters the water storage chamber through the air guide channel.

[0023] In one embodiment, the one-way valve is a baffle structure, which can rotate relative to the air duct housing and form at least a first position and a second position. When the air supply device stops working, the baffle structure is in the first position, and the air guide channel and the water storage chamber are disconnected; when the air supply device is working, the baffle structure is in the second position, and the air guide channel is connected to the water storage chamber.

[0024] The kettle in the above embodiment further defines the one-way valve as a baffle structure, which can rotate relative to the air duct housing. When the baffle is in the first position, the one-way valve is in a closed state, and when the baffle is in the second position, the one-way valve is in an open state.

[0025] In one embodiment, the air supply device is a fan or an air pump.

[0026] In one of the embodiments, a control device is further included, and the control device is arranged on the air duct housing, and the control device is electrically connected to the air supply device and the heating component respectively.

[0027] The kettle in the above embodiment further defines that a control device is provided on the air duct housing. Specifically, the control device is installed in the installation cavity. The control device can realize the linkage control of the heating component, the drive motor and the air supply device. For example, when the liquid is about to boil during heating, the control device controls the drive motor to rotate at a low speed to eliminate the formation of bubbles. When the liquid has finished boiling, the control device controls the drive motor to rotate quickly and controls the air supply device to work, thereby accelerating the cooling of the liquid.

[0038] A heating component 2, the heating component 2 is arranged on the kettle body 11 or the air duct housing 12 to heat the water storage chamber 101;

[0039] The air supply device 3 is disposed on the air duct housing 12 , and is used for sucking airflow from the first through hole 106 and guiding the airflow into the water storage chamber 101 .

[0040] The kettle disclosed in the present application has a kettle body 11 connected to an air duct shell 12, and a user can hold the air duct shell 12 to move the kettle body 11 or pour water, wherein a water storage chamber 101 is provided in the kettle body 11, and an air duct shell 12 is provided with an air guide channel 103 connected to the water storage chamber 101, and an air supply device 3 is provided on the air duct shell 12. The kettle can start the air supply device 3 automatically or manually. For example, after the water in the water storage chamber 101 is heated and boiled, the air supply device 3 is automatically started, and the air supply device 3 sucks air from the first through hole 106 and guides the air into the water storage chamber 101 through the air guide channel 103 to quickly cool down the liquid, thereby shortening the cooling time of the liquid and meeting the user's need to drink water of suitable temperature in time.

[0041] In addition to the features of the above-mentioned embodiment, the present embodiment further defines that: a temperature sensor is provided on the kettle body 11, and the temperature sensor is used to obtain the temperature of the liquid in the water storage chamber.

[0042] like Figures 1 to 4As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: the air duct housing 12 includes a handle 121 and a base 122, the base 122 is connected to the handle 121, an air guide channel 103 is formed in the handle 121, and a first through hole 106 and an installation cavity 108 are formed in the base 122, the first through hole 106, the installation cavity 108 and the air guide channel 103 are connected in sequence, and the air supply device 3 is installed in the installation cavity 108.

The air supply device 3 transmits the generated airflow to the water storage cavity 101 through the air guide channel 103. By opening the air guide channel 103 in the handle 121, it does not affect the user's hand-held movement, nor does it increase the overall volume of the kettle, making the overall design of the kettle reasonable. In addition, the handle 121 and the base 122 can be an integrally formed structure or a detachable structure.

[0044] like Figure 3 As shown, in addition to the features of the above-mentioned embodiments, the present embodiment further defines: a first opening 104 and a second opening 105 are provided on the air guide channel 103, the air guide channel 103 is connected with the installation cavity 108 through the first opening 104, the air guide channel 103 is connected with the water storage cavity 101 through the second opening 105, and the second opening 105 is located above the kettle body 11.

[0045] Among them, the second opening 105 in the air guide channel 103, which is away from one end of the installation cavity 108, is distributed above the kettle body 11, so that the airflow generated by the air supply device 3 blows from top to bottom through the air guide channel 103 on the top of the kettle body 11 to cool the liquid surface in the water storage cavity 101. At the same time, the second opening 105 is set above the kettle body 11, which can not only avoid the possibility of backflow of the air guide shell due to the low horizontal height of the second opening 105 on the kettle body 11, but also avoid the problem of too little water in the kettle body 11 due to the low horizontal height of the second opening 105 on the kettle body 11.

[0046] like Figures 1 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines: the kettle body 11 includes a kettle body 111 and a top cover 112, the top cover 112 is covered on the kettle body 111, and the top cover 112 is rotatably connected to one end of the handle 121 close to the second opening 105.

[0047] The handle 121 is located at the second opening 105 and rotates with the top cover 112. The top cover 112 can rotate relative to the handle 121 and form at least a first position and a second position. When the top cover 112 is in the first position, the top cover 112 is in an open state relative to the kettle body 111, so that the heat in the kettle body 111 can be better contacted with the outside world. When the top cover 112 is in the second position, the top cover 112 is in a closed state relative to the kettle body 111. In addition, the top cover 112 is rotatably arranged on the handle 121, so that no matter whether the top cover 112 is in the first position or the second position, it will not affect the effect of the air guide channel 103 supplying air to the water storage chamber 101.

[0048] In addition to the features of the above embodiments, this embodiment further defines that: the kettle body 11 and the air duct housing 12 are detachably connected.

The shape of the protrusion 1111 matches the shape of the first groove 107. The protrusion 1111 can be inserted into the first groove 107 to improve the stability of the connection between the hot kettle body 11 and the base 122.

[0050] like Figure 3 to Figure 4 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the air duct housing 12 is provided with a first air filter 4 at the first through hole 106 .

[0051] Among them, an air filter is provided at the first through hole 106 on the air duct housing 12, and the air filter can filter the air before entering the fan assembly, so as to transport clean cold air to the water storage chamber 101 to prevent the liquid from being contaminated.

[0052] In addition to the features of the above embodiments, this embodiment further defines that: a second air filter is provided in the air guide passage 103 .

[0053] In addition to the features of the above embodiments, this embodiment further defines that: the first air filter 4 and the air duct housing 12 are detachably connected.

[0058] In addition to the features of the above embodiments, this embodiment further defines that: the air supply device 3 is a fan or an air pump.

[0059] The air supply device 3 may be a fan or an air pump. Figure 3 As shown, the air supply device 3 is a blower, and one end of the blower outlet passes through the first opening 104 and extends into the air guide channel 103102, so that the airflow generated by the blower is almost transported from the air guide channel 103 to the water storage chamber 101, thereby improving the air supply efficiency and accelerating the cooling speed.

[0060] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines: the kettle also includes a control device, the control device is arranged on the air duct housing 12, and the control device is electrically connected to the air supply device 3 and the heating component 2 respectively.

[0061] Among them, a control device is provided on the air duct shell 12. Specifically, the control device is installed in the installation cavity 108. The control device can realize the linkage control of the heating component 2, the driving motor and the air supply device 3. For example, when the liquid is about to boil during the heating process, the control device controls the driving motor to rotate at a low speed to eliminate the formation of bubbles. When the liquid is finished boiling, the control device controls the driving motor to rotate quickly and controls the air supply device 3 to work, thereby accelerating the cooling of the liquid.

[0062] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present utility model patent shall be subject to the attached claims.
