Description

TECHNICAL FIELD

[0001] The utility model relates to the field of drinking water equipment, especially to a drinking water equipment of quick cooling. BACKGROUND

[0002] The electric kettle is a kind of common electric appliance for drinking water. After the water in the electric kettle is heated to boiling, the user needs to wait for the water to cool down to the appropriate drinking temperature range before drinking. The conventional electric kettle generally cools down by natural heat dissipation, which has low heat dissipation efficiency, resulting in a long waiting time for the user to drink after the water is boiled. This brings inconvenience to the user. There is a constant-temperature drinking water device on the market, which can automatically cool down the boiled water to the appropriate temperature for the user to drink. The prior art, as disclosed in the utility model patent with the publication number CN220275382U, places the kettle body in the main shell with an inner cavity, forms a gap between the inner cavity and the kettle body, and sets the air inlet around the kettle body. A plurality of air deflectors are arranged at the air inlet. The air deflectors are inclined relative to the horizontal plane, so that the air flow spirally rises or descends along the outer wall of the kettle body, and the air flow that absorbs the heat of the kettle body is discharged from the air outlet. This method is limited to strengthening the airflow around the kettle body, and the heat dissipation efficiency of the water in the kettle body is not significantly improved. As disclosed in the utility model patent with the publication number CN216907615U, a heating cavity is arranged in the kettle body, and a cooling cavity is arranged around the outer wall of the heating cavity. A cooling water tank is in communication with the cooling cavity to supply cooling water into the cooling cavity. The cooling water in the cooling cavity exchanges heat with the water in the heating cavity to cool the water in the heating cavity. This method improves the heat dissipation efficiency by changing the medium from air to water, but it still cannot avoid the fact that the water must first exchange heat with the kettle body, which is usually made of plastic with low thermal conductivity, resulting in limited improvement in the heat dissipation efficiency of the water in the heating cavity and a long cooling time. Therefore, there is a need for a solution that can effectively improve the heat dissipation efficiency of the water in the kettle and reduce the cooling time required for drinking. SUMMARY

[0034] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The features in the following embodiments can be combined with each other without conflict.

[0035] As Figures 1-7The utility model provides a kind of water drinking equipment of quick cooling, including shell 1 and liquid container 2, liquid container 2 is combined on shell by coupler 21.It also includes heat sink 3, circulating water pump 4 and cooling fan 5, specifically, heat sink 3 has multiple heat dissipation fins 31 arranged at intervals and heat dissipation pipe 32 embedded in multiple heat dissipation fins 31, heat dissipation fin 31 is made of aluminum or copper, to realize quick heat conduction, heat dissipation pipe 32 can use stainless steel, to ensure drinking water quality and heat conduction performance simultaneously.Circulating water pump 4 is preferably connected with heat dissipation pipe 32 and liquid container 2 by silica gel pipe, to form the communication loop of fluid, and circulating water pump 4 extracts liquid from liquid container 2 and returns to liquid container after flowing through heat dissipation pipe 32;Cooling fan 5 is arranged at the position corresponding to heat dissipation fin 31, so that cooling wind passes through the gap between heat dissipation fin 31 to cool heat dissipation pipe 32, and the heat of liquid is transferred to heat dissipation fin 31 via heat dissipation pipe 32, and then cooling fan 5 dissipates heat to air.In order to prolong the length of heat dissipation pipe 32 passing through heat dissipation fin, so that good heat exchange can be realized between heat dissipation pipe 32 and heat dissipation fin 31, heat dissipation pipe has multiple heat dissipation sections 33 arranged in a set manner, and liquid flows out of heat dissipation fin 31 via the multiple heat dissipation sections.

[0036] Compared with the prior art, the utility model extracts liquid from liquid container by circulating water pump and returns it to liquid container, so that the liquid in liquid container forms internal and external circulation, without heat exchange through liquid container itself, which significantly improves the heat dissipation efficiency of liquid in liquid container.In addition, the heat dissipation device with heat dissipation pipe and cooling fan enables the heat of heat dissipation pipe and liquid therein to be quickly dissipated to air through heat dissipation device, so that the liquid in liquid container can be quickly cooled to a suitable temperature.In particular, under the condition that cooling fan and heat dissipation device are properly configured and the flow of circulating water pump is sufficient, the water drinking equipment provided by the utility model can reduce the liquid in liquid container from 100 DEG C to about 50 DEG C suitable for drinking in about 5 minutes.

[0037] In addition, the greater the liquid circulation flow, the faster the heat exchange rate with heat dissipation device.Preferably, the flow of circulating water pump 4 can be configured to be not less than 2.5L / min, so that liquid can be quickly circulated and dissipated, and the inner diameter of heat dissipation pipe 32 can be preferably configured to be not less than 10mm, so that liquid flows smoothly in circulation pipeline.

[0038] As Figure 6 , Figure 7As shown, the plurality of heat dissipation sections 33 are preferably arranged in parallel, so as to effectively utilize the internal space of the heat dissipation device 3, to extend the length of the heat dissipation pipes 32 as much as possible in the heat dissipation fins 31, to accelerate the heat exchange rate between the heat dissipation pipes and the heat dissipation fins, and to ensure that the heat in the heat dissipation pipes 32 can be quickly conducted away. The plurality of heat dissipation sections 33 can also be arranged in other ways, such as spirally. Further, the plurality of heat dissipation sections 33 are arranged in a staggered manner in the horizontal direction, so that the structure of the heat dissipation device 3 is more compact, and the space required for the housing 1 to accommodate the heat dissipation device is reduced. Preferably, the plurality of heat dissipation sections 33 can be integrally connected or connected by silicone pipes, and the connection parts are preferably smoothly transitioned to reduce the resistance of the liquid flowing in the pipes.

[0039] As shown in Figure 1 , Figure 2 , Figure 5 , Figure 6 , the heat dissipation device 3 has an air inlet side 301 and an air outlet side 302, and the heat dissipation fan 5 is arranged close to the air inlet side 301, so that the cooling air blown by the heat dissipation fan 5 can effectively pass through the gaps between the heat dissipation fins 31; the liquid container 2 is arranged on the housing 1 close to the air outlet side 302, so that the air flow from the air outlet side 302 flows through the liquid container 2. The air flow from the heat dissipation fan 5 has a higher temperature than air after passing through the heat dissipation device 3, but is still lower than the temperature of the liquid container 2 and the liquid in the liquid container. By arranging the liquid container 2 in this way, the air flow from the air outlet side 302 can play a supplementary cooling role. The housing 1 has an air outlet 11 arranged between the air outlet side 302 and the liquid container 2, and the air outlet 11 is in a honeycomb network shape to balance the appearance and good air flow. Correspondingly, an air inlet 12 is arranged at the bottom of the housing 1, and preferably, a filter screen can be arranged at the air inlet 12 to prevent dust from being sucked into the interior of the housing 1 by the heat dissipation fan 5.

[0040] As shown in Figures 5-7 , since the heat dissipation device 3 is generally long and rectangular, one heat dissipation fan 5 is not enough to cover the surface of the entire air inlet side 301, and one heat dissipation fan 5 cannot meet the heat dissipation requirements of the heat dissipation pipes 32, therefore, the heat dissipation fan 5 is preferably configured with at least two. According to the actual needs of the size and heat dissipation rate of the heat dissipation device 3, more heat dissipation fans 5 can also be configured, and at the same time, the size of the heat dissipation device 3 should be adapted to the number and size of the heat dissipation fans 5, to ensure that two or more heat dissipation fans 5 can basically completely cover the air inlet side 301. Further, the liquid container 2 is configured with a temperature measuring probe 22 that can measure the temperature of the liquid, thereby generating a temperature feedback signal, and can cooperate with the control circuit to control the start and stop of the heat dissipation fan 5.

[0041] As shown in Figures 2-4As shown, as a preferred, the liquid container 2 is provided with a water outlet 23 and a backwater outlet 24, when the circulating water pump 4 is running, the liquid in the liquid container 2 flows out from the water outlet 23 and returns to the liquid container from the backwater outlet 24. The water outlet 23 and the backwater outlet 24 are preferably arranged at the bottom of the liquid container 2 to facilitate the liquid extraction by the circulating water pump 4. It should be understood that the arrangement position of the water outlet 23 and the backwater outlet 24 is not limited thereto, as long as the liquid can be extracted and circulated, for example, the water outlet can also be arranged at the side of the liquid container 2 close to the lower part, and the backwater outlet is arranged at the top of the liquid container 2. In addition, the water outlet 23 and the backwater outlet 24 are preferably provided with one-way valves 25, 26, which are opened only when the liquid container 2 is coupled with the coupler 21, thereby preventing the liquid from leaking out of the water outlet and the backwater outlet when the liquid container 2 is lifted, causing inconvenience to the use.

[0042] As shown in the drawings, Figures 3-5 As a preferred, the water outlet 23 is arranged at the center of the bottom of the liquid container 2, and in the embodiment, the water outlet 23 is at the through hole in the center of the coupler 21, so that the structure of the water drinking device is compact. In addition, the backwater outlet 24 should be arranged at a distance from the water outlet 23 to prevent the cold flow at the backwater outlet 24 from being sucked into the water outlet 23 again, causing a local circulation and affecting the cooling effect.

[0043] As shown in the drawings, Figure 1 、 Figure 5 、 Figure 6 The shell 1 is also provided with a drinking water pump 41 and a drinking water outlet 13, specifically, the drinking water pump 41 is in fluid communication with the drinking water outlet 13 and the water outlet 23 through a silica gel pipe, and the drinking water pump 41 extracts the liquid in the liquid container 2 from the water outlet 23 and discharges it to the drinking water outlet 13 for the user to drink.

[0044] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
