Description

Technical Field

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

[0002] In daily life, people are used to drinking boiled water, so electric kettles with rapid cooling 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 it can be drunk. However, the efficiency of heat exchange between the kettle and the air by simply dissipating heat is very low, that is, it takes a long time for the water temperature to drop to a temperature suitable for drinking. This greatly affects our daily life and wastes time. Most electric kettles with rapid cooling have an insulation cover on the surface, which only considers heat preservation but does not have a cooling function. Compared with heat preservation, the 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 quick cooling 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 quick cooling 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 solve the above problems of the existing fast cooling kettle and provide a fast cooling kettle.

[0005] The fast cooling kettle provided by the present application comprises:

[0006] A kettle body, wherein the kettle body is provided with a water storage cavity having an opening and a spout communicated with the water storage cavity;

[0007] A heat dissipation device, the heat dissipation device comprising an upper cover and a heat dissipation fan, the upper cover movable cover is arranged at the opening of the kettle body, and the heat dissipation fan is arranged on the upper cover;

[0008] The upper cover and the kettle body are respectively provided with a first conductive contact and a second conductive contact, and the heat dissipation fan, the first conductive contact, the second conductive contact and the kettle body form a power supply circuit.

[0009] The fast cooling kettle disclosed in the present application is provided with a first conductive contact and a second conductive contact on the upper cover and the kettle body respectively. When the upper cover is arranged on the kettle body, the first conductive contact establishes an electrical connection with the second conductive contact, and the power supply module in the kettle body supplies power to the heat dissipation fan, thereby reducing the complexity of the power supply circuit formed by the kettle body and the heat dissipation fan; the upper cover is arranged at the opening of the kettle body, and when the heat dissipation fan is installed on the upper cover, the heat dissipation fan is powered to generate suction, so that the external lower temperature airflow is sucked into the water storage chamber, and the lower temperature airflow conducts heat with the higher temperature water in the water storage chamber, and the airflow that completes the heat conduction is discharged through the spout. Compared with natural cooling, the kettle of the present application can quickly cool down the boiling water, reduce the waiting time, and improve the user experience.

[0010] In one of the embodiments, the upper cover is provided with an air guiding cavity and a first through hole and a second through hole connected to the air guiding cavity, the heat dissipation fan is installed in the air guiding cavity, and the second through hole is arranged opposite to the air outlet of the heat dissipation fan.

[0011] The fast cooling kettle in the above embodiment is further defined as a wind guide cavity for installing a heat dissipation fan formed inside the upper cover. When the heat dissipation fan is working, suction is generated, so that the external air flow is sucked into the heat dissipation fan through the first through hole for acceleration. The accelerated air flow is introduced into the water storage cavity through the second through hole, and heat is transferred to the hot water in the water storage cavity.

[0012] In one of the embodiments, the heat dissipation device further includes a filter assembly, which is installed in the air guide cavity and is located between the first through hole and the air inlet of the heat dissipation fan.

[0013] The fast cooling kettle in the above embodiment is further defined as having a filter assembly disposed between the first through hole and the air inlet of the heat dissipation fan. When the heat dissipation fan inhales external airflow from the first through hole, the first through hole first performs preliminary filtration on impurities with larger volumes in the airflow. After the preliminary filtration, the airflow is deeply filtered for harmful fine impurities in the airflow under the action of the filter assembly, so that the airflow entering the water storage chamber is purified, thereby avoiding contamination of the water in the water storage chamber.

[0014] In one embodiment, the upper cover includes an upper shell, a lower shell and a first bracket, the upper shell is detachably connected to the lower shell, the upper shell and the lower shell are enclosed to form the air guide cavity, the first bracket is located in the air guide cavity, and the filter assembly is arranged on the first bracket.

[0015] The kettle for rapid cooling in the above embodiment further defines that the upper shell and the lower shell are detachably connected. After the upper shell and the lower shell are detached, the filter assembly can be replaced or cleaned after being used for a period of time to improve the purification effect. In addition, by installing the filter assembly on the first bracket, a gap is left between the filter assembly and the air inlet of the heat dissipation fan, thereby ensuring the air intake of the heat dissipation fan.

[0016] In one of the embodiments, the heat dissipation device further includes a switch valve, which is installed in the air guide cavity, and the air outlet of the heat dissipation fan is selectively connected to the second through hole through the switch valve.

[0017] The kettle with rapid cooling in the above embodiment is further limited to selectively connecting the air outlet of the heat dissipation fan with the second through hole through the switch valve. Specifically, during the process of boiling water in the kettle body, the switch valve is in a closed state, and the air outlet of the heat dissipation fan is disconnected from the second through hole. When the heat dissipation fan needs to be turned on to cool the hot water in the water storage chamber, the switch valve is opened to connect the air outlet of the heat dissipation fan with the second through hole, so that the airflow accelerated by the heat dissipation fan enters the water storage chamber from the second through hole.

[0018] In one embodiment, the switch valve includes a partition and a push rod, the partition is connected to the push rod, the partition is clamped between the air outlet of the heat dissipation fan and the second through hole, the partition is provided with a third through hole, the partition can rotate relative to the upper cover and form at least a first position and a second position, when the partition is in the first position, the projection of the third through hole on the upper cover at least partially overlaps with the second through hole, when the partition is in the second position, the projection of the third through hole on the upper cover falls outside the range of the second through hole, and the push rod can slide relative to the upper cover to drive the partition to switch between the first position and the second position.

[0019] The kettle for rapid cooling in the above embodiment is further defined as being provided with a partition between the air outlet of the heat dissipation fan and the second through hole, the partition being provided with a third through hole, and the partition being rotatable relative to the upper cover and forming at least a first position and a second position, and the opening and closing of the switch valve can be controlled by driving the push rod to slide relative to the upper cover. Specifically, when the partition is in the first position, the projection of the third through hole on the upper cover at least partially overlaps with the second through hole, and the airflow can enter the water storage chamber through the part where the third through hole overlaps with the second through hole, and the switch valve is in an open state at this time; when the partition is in the second position, the projection of the third through hole on the upper cover falls outside the range of the second through hole, and the switch valve is in a closed state at this time. Based on the connection between the push rod and the partition, the partition is driven to slide relative to the upper cover to rotate back and forth between the first position and the second position, thereby realizing the switching of the switch valve between opening and closing.

[0020] In one embodiment, the level of the spout is lower than the levels of the first conductive contact and the second conductive contact.

[0021] The fast cooling kettle in the above embodiment further limits the horizontal heights of the first conductive contact and the second conductive contact to be lower than the horizontal height of the spout. When the water level in the water storage chamber is too high, the water above the spout overflows from the spout into the water storage chamber, thereby preventing the first conductive contact and the second conductive contact from contacting the water and affecting the safety of use.

[0022] In one embodiment, the kettle body includes a kettle body, a heating plate and a power socket, the heating plate and the power socket are respectively arranged on the kettle body, the second conductive contact is arranged on the kettle body, and the heating plate and the second conductive contact are both electrically connected to the power socket.

[0023] In one embodiment, the kettle body includes a kettle body and a handle, the handle is connected to the kettle body, a limiting groove is provided on the side wall of the upper cover, the first conductive contact is arranged in the limiting groove, and the second conductive contact is arranged on the handle, and when part of the handle is inserted into the limiting groove, the first conductive contact abuts against the second conductive contact and is electrically connected.

[0024] The fast cooling kettle in the above embodiment is further defined as a limiting groove provided on the side wall of the upper cover, in which a first conductive contact is installed, and a first conductive contact is installed on a handle matching the shape of the limiting groove. When the handle portion equipped with the first conductive contact is inserted into the limiting groove, the first conductive contact abuts against the second conductive contact, thereby establishing an electrical connection.

[0025] In one embodiment, the kettle further includes a stirring device, which includes a driving motor and a stirring blade. The heating plate divides the space formed in the kettle body into the water storage chamber and the installation chamber. The driving motor is installed in the installation chamber. The rotating shaft of the driving motor passes through the heating plate and extends into the water storage chamber and is transmission-connected to the stirring blade.

[0026] The fast cooling kettle in the above embodiment further defines that the driving motor can drive the stirring blades in the water storage chamber to rotate. When the water is about to boil, the bubbles generated make a sound of bubbles popping on the heating plate in the kettle body. The stirring blades are rotated slowly to eliminate the formation of bubbles, thereby eliminating the sound of bubbles popping and achieving a silent effect. When the hot water in the water storage chamber needs to be cooled, the stirring blades are rotated quickly to form a vortex in the water storage chamber, thereby increasing the heat dissipation area, accelerating the heat conduction between the airflow and the water, and thus improving the cooling effect.

[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0038] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0039] like Figures 1 to 5 As shown, this embodiment provides a kettle for rapid cooling, comprising:

[0040] The kettle body 1 is provided with a water storage cavity 101 having an opening and a spout 102 communicating with the water storage cavity 101;

[0041] The heat dissipation device 2 includes an upper cover 21 and a heat dissipation fan 22. The upper cover 21 is movable and arranged at the opening of the kettle body 1. The heat dissipation fan 22 is arranged on the upper cover 21.

[0042] The upper cover 21 and the kettle body 1 are provided with a first conductive contact 41 and a second conductive contact 42 respectively. The heat dissipation fan 22, the first conductive contact 41, the second conductive contact 42 and the kettle body 1 form a power supply circuit.

[0043] The kettle body can heat the water in the water storage chamber 101 to boiling. The water storage chamber 101 can be used to store water. For example, a heating element is provided on the outer wall or the inner wall of the water storage chamber 101 to heat the water in the water storage chamber 101.

[0044] The upper cover 21 is movably disposed on the kettle body 1, and the upper cover 21 can be removed from the kettle body. The heat dissipation fan 22 can draw the external low-temperature airflow into the water storage chamber 101. When the low-temperature airflow enters the water storage chamber 101, heat is transferred to the high-temperature water. The airflow that has completed the heat transfer is discharged through the spout 102 to achieve the cooling function.

[0045] Before the upper cover 21 is installed on the kettle body 1, the first conductive contact 41 is electrically connected to the heat dissipation fan 22, and the second conductive contact 42 is electrically connected to the power supply module of the kettle body 1. When the upper cover 21 is installed on the kettle body 1, the first conductive contact 41 abuts against the second conductive contact 42, so that the power supply module in the kettle body 1 is electrically connected to the heat dissipation fan 22, thereby supplying power to the heat dissipation fan 22.

[0046] In the above-mentioned embodiments, the hot water kettle with rapid cooling is provided with a first conductive contact 41 and a second conductive contact 42 on the upper cover 21 and the hot water kettle body 1 respectively. When the upper cover 21 is covered on the hot water kettle body 1, the first conductive contact 41 and the second conductive contact 42 establish an electrical connection, and the power supply module in the hot water kettle body 1 supplies power to the heat dissipation fan 22, thereby reducing the complexity of the power supply circuit formed by the hot water kettle body 1 and the heat dissipation fan 22; when the upper cover 21 is covered at the opening of the hot water kettle body 1 and the heat dissipation fan 22 is installed on the upper cover 21, the heat dissipation fan 22 is powered to generate suction, so that the external lower temperature airflow is sucked into the water storage chamber 101, and the lower temperature airflow conducts heat with the higher temperature water in the water storage chamber 101, and the airflow that completes the heat conduction is discharged through the spout 102. Compared with natural cooling, the hot water kettle of the present application can quickly cool down the boiled water, reduce the waiting time, and improve the user experience.

[0047] like Figure 2 and Figure 5 As shown, in addition to the features of the above-mentioned embodiments, this embodiment is further defined as follows: the upper cover 21 is provided with an air guide cavity 201 and a first through hole 202 and a second through hole 203 connected to the air guide cavity 201; the heat dissipation fan 22 is installed in the air guide cavity 201; the second through hole 203 is arranged opposite to the air outlet of the heat dissipation fan 22.

[0048] Based on the fact that an air guide cavity 201 for installing the heat dissipation fan 22 is formed inside the upper cover 21, when the heat dissipation fan 22 is working, suction is generated, so that the external airflow is sucked into the heat dissipation fan 22 through the first through hole 202 for acceleration, and the accelerated airflow is introduced into the water storage cavity 101 through the second through hole 203, and heat is transferred to the hot water in the water storage cavity 101. Among them, the number of the first through holes 202 can be one or more. For example, the number of the first through holes 202 is multiple, and by limiting the diameter of the first through hole 202, it is possible to prevent debris larger than the diameter of the first through hole 202 from entering the air guide cavity 201, thereby avoiding contamination of the water in the water storage cavity 101.

[0049] like Figure 2 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines: the heat dissipation device 2 also includes a filter assembly 23, the filter assembly 23 is installed in the air guide cavity 201, and the filter assembly 23 is located between the first through hole 202 and the air inlet of the heat dissipation fan 22.

[0050] Based on the fact that a filter assembly 23 is provided between the first through hole 202 and the air inlet of the heat dissipation fan 22, when the heat dissipation fan 22 inhales the external airflow from the first through hole 202, the first through hole 202 first performs a preliminary filtration on the impurities with a larger volume in the airflow, and the airflow after the preliminary filtration is deeply filtered by the filter assembly 23 for the harmful fine impurities in the airflow, so that the airflow entering the water storage chamber 101 is purified to avoid contamination of the water in the water storage chamber 101. Among them, the filter assembly 23 can be, but is not limited to, physical adsorption or electrostatic dust removal. For example, the filter assembly 23 is a filter net, and the filter net can be one or a combination of synthetic fiber filter cotton, non-woven filter cotton, glass fiber filter cotton, and activated carbon filter cotton. When the airflow passes through the filter net, the fine particles entrained in the airflow are adsorbed on the filter net.

[0051] like Figure 2 and Figure 5 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: the upper cover 21 includes an upper shell 211, a lower shell 212 and a first bracket 213, the upper shell 211 and the lower shell 212 are detachably connected, the upper shell 211 and the lower shell 212 are combined to form an air guide cavity 201, the first bracket 213 is located in the air guide cavity 201, and the filter assembly 23 is arranged on the first bracket 213.

[0052] Since the upper shell 211 and the lower shell 212 are detachably connected, after the upper shell 211 and the lower shell 212 are detached, the filter assembly 23 can be replaced or cleaned after being used for a period of time to improve the purification effect. In addition, by installing the filter assembly 23 on the first bracket 213, a gap is left between the filter assembly 23 and the air inlet of the heat dissipation fan 22 to ensure the air intake of the heat dissipation fan 22.

[0053] like Figure 2 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines: the heat dissipation device 2 also includes a switch valve 24, the switch valve 24 is installed in the air guide cavity 201, and the air outlet of the heat dissipation fan 22 is selectively connected to the second through hole 203 through the switch valve 24.

[0054] The air outlet of the heat dissipation fan 22 is selectively connected to the second through hole 203 through the switch valve 24. Specifically, during the process of boiling water in the kettle body 1, the switch valve 24 is in a closed state, and the air outlet of the heat dissipation fan 22 is disconnected from the second through hole 203. When the heat dissipation fan 22 needs to be turned on to cool the hot water in the water storage chamber 101, the switch valve 24 is opened to connect the air outlet of the heat dissipation fan 22 to the second through hole 203, so that the airflow accelerated by the heat dissipation fan 22 enters the water storage chamber 101 from the second through hole 203. It should be noted that the switch valve 24 can be an electric valve or a manual valve.

[0055] like Figure 2 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines: the switch valve 24 includes a partition 241 and a push rod 242, the partition 241 is connected to the push rod 242, the partition 241 is clamped between the air outlet of the heat dissipation fan 22 and the second through hole 203, the partition 241 is provided with a third through hole 205, the partition 241 can rotate relative to the upper cover 21 and form at least a first position and a second position, when the partition 241 is in the first position, the projection of the third through hole 205 on the upper cover 21 at least partially overlaps with the second through hole 203, when the partition 241 is in the second position, the projection of the third through hole 205 on the upper cover 21 falls outside the range of the second through hole 203, and the push rod 242 can slide relative to the upper cover 21 to drive the partition 241 to switch between the first position and the second position.

[0056] Based on the partition 241 disposed between the air outlet of the heat dissipation fan 22 and the second through hole 203, the partition 241 is provided with the third through hole 205, and the partition 241 can rotate relative to the upper cover 21 and form at least a first position and a second position, the opening and closing of the switch valve 24 can be controlled by driving the push rod 242 to slide relative to the upper cover 21. Specifically, when the partition 241 is in the first position, the projection of the third through hole 205 on the upper cover 21 at least partially overlaps with the second through hole 203, and the airflow can enter the water storage chamber 101 through the portion where the third through hole 205 overlaps with the second through hole 203, and at this time the switch valve 24 is in an open state, and when the partition 241 is in the second position, the projection of the third through hole 205 on the upper cover 21 falls outside the range of the second through hole 203, and at this time the switch valve 24 is in a closed state. Based on the connection between the push rod 242 and the partition 241 , the partition 241 is rotated back and forth between the first position and the second position by driving the push rod 242 to slide relative to the upper cover 21 , thereby realizing the switching of the switch valve 24 between opening and closing.

[0057] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the level of the spout 102 is lower than the level of the first conductive contact 41 and the second conductive contact 42 .

[0058] Since the levels of the first conductive contact 41 and the second conductive contact 42 are both lower than the level of the spout 102, when the water level in the water storage chamber 101 is too high, the water above the spout 102 overflows from the spout 102 into the water storage chamber 101, thereby preventing the first conductive contact 41 and the second conductive contact 42 from contacting with water and affecting safety of use.

[0059] like Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment further defines: the kettle body 1 includes a kettle body 11, a heating plate 12 and a power socket 13, the heating plate 12 and the power socket 13 are respectively arranged on the kettle body 11, the second conductive contact 42 is arranged on the kettle body 11, and the heating plate 12 and the second conductive contact 42 are both electrically connected to the power socket 13.

[0060] The power socket 13 can supply power to the heating plate 12 and the second conductive contact 42. Specifically, a power supply module is provided on the power socket 13, and a coupler electrically connected to the power supply module is provided at the bottom of the kettle body 11. The coupler is electrically connected to the heating plate 12 and the second conductive contact 42, and the power supply module establishes a power supply circuit with the heating plate 12 and the second conductive contact 42 through the coupler. In addition, the power socket 13 can be detachably connected to the kettle body 11, which can achieve rapid disassembly without affecting the air intake of the first through hole 202.

[0061] like Figures 1 to 5 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 handle 112, the handle 112 is connected to the kettle body 111, a limiting groove 204 is provided on the side wall of the upper cover 21, the first conductive contact 41 is arranged in the limiting groove 204, and the second conductive contact 42 is arranged on the handle 112, when part of the handle 112 is inserted into the limiting groove 204, the first conductive contact 41 abuts against the second conductive contact 42 and is electrically connected.

[0062] Based on the side wall of the upper cover 21, a limiting groove 204 is provided, and a first conductive contact 41 is installed in the limiting groove 204. The first conductive contact 41 is installed on the handle 112 that matches the shape of the limiting groove 204. When the handle 112 with the first conductive contact 41 is partially inserted into the limiting groove 204, the first conductive contact 41 abuts against the second conductive contact 42, thereby establishing an electrical connection. Specifically, the horizontal height of part of the handle 112 is higher than the horizontal height of the opening of the kettle body 11. Before the upper cover 21 is placed on the kettle body 11, the part of the handle 112 that is higher than the opening of the kettle body 11 is first inserted into the limiting groove 204, so that the first conductive contact 41 and the second conductive contact 42 are positioned, ensuring the stability of the electrical connection between the first conductive contact 41 and the second conductive contact 42.

[0063] like Figure 2 As shown, in addition to the features of the above embodiments, the present embodiment further defines: the kettle also includes a stirring device 3, the stirring device 3 includes a driving motor 31 and a stirring blade 32, the heating plate 12 divides the space formed in the kettle body 11 into a water storage chamber 101 and an installation chamber, the driving motor 31 is installed in the installation chamber, and the rotating shaft of the driving motor 31 passes through the heating plate 12 and then extends into the water storage chamber 101 and is transmission-connected to the stirring blade 32.

[0064] Since the driving motor 31 can drive the stirring blade 32 in the water storage chamber 101 to rotate, when the water is about to boil, the bubbles generated make a sound of bubbles popping on the heating plate in the kettle body 11. The stirring blade 32 is rotated slowly to eliminate the formation of bubbles, thereby eliminating the sound of bubbles popping, and achieving a silent effect; when the hot water in the water storage chamber 101 needs to be cooled, the stirring blade 32 is rotated quickly to form a vortex in the water storage chamber 101, thereby increasing the heat dissipation area, accelerating the heat conduction between the airflow and the water, and thus improving the cooling effect.

[0065] The technical features of the above embodiments may be combined arbitrarily. 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.

[0066] 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.
