Description

Technical Field

[0001] This utility model relates to water-using equipment, and more particularly to a drinking water device. Background Technology

[0002] Some existing drinking water systems can rapidly cool boiled water and output warm water for direct consumption. These systems include a base, a hot water supply mechanism, a cooling water supply mechanism, and a heat exchange component. The heat exchange component uses a double-layered tube system, consisting of an inner and outer tube arranged coaxially. A cooling channel is formed between the inner and outer tubes. The inner tube carries hot water, while the cooling channel carries cooling water. The cooling water supply mechanism supplies cooling water to the cooling channel. The hot water output from the hot water supply mechanism flows through the inner tube before being output. During this process, the hot water indirectly exchanges heat with the cooling water in the cooling channel through the inner tube, thus cooling the water and allowing it to directly output warm water for drinking. However, to rapidly cool the hot water, the double-layered tube system usually needs to be quite long, making its manufacturing and assembly difficult and resulting in high production costs for the drinking water system.

[0030] Reference Figures 1 to 4 This invention relates to a drinking water device, which includes a base 100, a hot water supply mechanism 200, a coolant supply mechanism 300, and a heat exchange component 400. A hot water supply mechanism 200 is installed on the base 100, and the hot water supply mechanism 200 is provided with a hot water outlet 211; a coolant supply mechanism 300 is installed on the base 100, and the coolant supply mechanism 300 is provided with a cold liquid outlet 311; a heat exchange assembly 400 is installed on the base 100, and the heat exchange assembly 400 includes a tube body 410 and two plates 420. The tube body 410 has a heat exchange section 411, and the two plates 420 are stacked and form a cooling channel 430. The heat exchange section 411 is located between the two plates 420 and within the cooling channel 430; wherein the inlet end of the tube body 410 is connected to the hot water outlet 211 of the hot water supply mechanism 200, the outlet end of the tube body 410 is used to output drinking water, and the inlet end of the cooling channel 430 is connected to the cold liquid outlet 311.

[0031] The hot water supply mechanism 200 outputs hot water to the pipe body 410 through the hot water outlet 211, and the coolant supply mechanism 300 outputs coolant to the cooling channel 430 through the coolant outlet 311. During the flow of hot water through the pipe body 410, it indirectly exchanges heat with the coolant in the cooling channel 430 at the heat exchange section 411, thereby being rapidly cooled, and finally, warm water flows out at the output end of the pipe body 410. Since the heat exchange section 411 of the pipe body 410 of the heat exchange component 400 is located between two plates 420, the two plates 420 can be stacked to form the cooling channel 430. The heat exchange section 411 is located in the cooling channel 430. Compared with the method of manufacturing nested tubes, the manufacturing and assembly difficulty of the heat exchange component 400 can be significantly reduced, thereby reducing the production cost of the drinking water device.

[0032] It should be understood that the pipe body 410 and the cooling channel 430 can also be interchanged. For example, the inlet end of the cooling channel 430 is connected to the hot water outlet 211 of the hot water supply mechanism 200, the outlet end of the cooling channel 430 is used to output drinking water, and the inlet end of the pipe body 410 is connected to the coolant outlet 311. That is, the cooling channel 430 is used to transport drinking water, and the pipe body 410 is used to transport coolant.

[0033] Specifically, in this embodiment, the coolant is water, which has low usage costs and is relatively easy to replenish. It is understood that in other embodiments, the coolant may also be, for example, cooling oil, and this is not limited here.

[0034] In this embodiment, the cooling channel 430 is arranged along the length of the heat exchange section 411, which is bent, and the central axes of the heat exchange section 411 are all located in the same plane. The bent arrangement of the heat exchange section 411 increases its length between the two plates 420, resulting in a longer cooling channel 430 and thus better cooling of boiling water. Since the two plates 420 are stacked to form the cooling channel 430, when the central axes of the heat exchange section 411 are in the same plane, the structure of the two plates 420 can be relatively simple to form the cooling channel 430, reducing the manufacturing difficulty of the plates 420 and the tube 410.

[0035] In this embodiment, the heat exchange section 411 is arranged in a serpentine bend, forming multiple straight sections 4111 and at least two bent sections 4112. Each straight section 4111 is arranged in the left-right direction, and all straight sections 4111 are arranged in the up-down direction. All straight sections 4111 are connected in series through the bent sections 4112 to form a whole. The two plates 420 are placed on the front and rear sides of the heat exchange section 411. The corresponding cooling channel 430 also has a similar shape. The heat exchange section 411, which is similar to a serpentine bend, can make good use of the length and width dimensions of the plate 420 to form a longer cooling channel 430 as much as possible, so that the volume between the heat exchange section 411 and the plate 420 is smaller, reducing material costs.

[0036] Specifically, there can be three, four or more straight segments 4111, and two, three or more corresponding bent segments 4112, which are not limited here. It should be understood that if the number of straight segments 4111 in this embodiment is N, then the number of bent segments 4112 is N-1.

[0037] It should be understood that the central axis of the heat exchange section 411 can also be located on a horizontal plane. In this case, the heat exchange section 411 can be bent back and forth on the horizontal plane to form an approximately serpentine bend, which can also have the same function of cooling drinking water. In this case, the two plates 420 are placed on the upper and lower sides of the heat exchange section 411 respectively.

[0038] Specifically, each straight section 4111 of the heat exchange section 411 has the same length, and each bent section 4112 has the same bending radius, so that all the straight sections 4111 are evenly arranged, which facilitates processing and manufacturing.

[0039] In this embodiment, the plate 420 is arranged vertically, with the inlet of the heat exchange section 411 located at its lower part and the outlet of the heat exchange section 411 located at its upper part. Similarly, the inlet of the cooling channel 430 is located at its lower part, and the outlet of the cooling channel 430 is located at its upper part. This layout not only facilitates a stable and smooth flow of drinking water but also ensures that the drinking water flowing from the outlet of the pipe 410 is at a temperature close to warm rather than too low, making it more suitable for direct consumption.

[0040] It is conceivable that in other embodiments, the heat exchange section 411 may also have other shapes, such as a planar spiral bend or other irregular bends, as long as the central axis of the heat exchange section 411 is located in the same plane.

[0041] In this embodiment, both plates 420 are provided with strip grooves 421. The openings of the two strip grooves 421 are joined together to form a cooling channel 430. The method of forming the cooling channel 430 is relatively simple and easy to implement. Specifically, the cross-section of the strip groove 421 is semi-circular, and the cooling channel 430 is circular. It is conceivable that in some other embodiments, one plate 420 may be provided with a strip groove 421, and the other plate 420 may be a flat plate. When the two are stacked, the flat plate covers the opening of the strip groove 421, which can also form a cooling channel 430.

[0042] In this embodiment, the hot water supply mechanism 200 includes a hot water bottle 210, a heater 220, and a hot water pump 230. The heater 220 is connected to the hot water bottle 210, which has a hot water outlet 211. The hot water outlet 211 is connected to the inlet of the pipe body 410 via the hot water pump 230. Users can directly fill the hot water bottle 210 with water, which is then boiled by the heater 220. The water in the hot water bottle 210 flows through the hot water outlet 211 to the hot water pump 230 and is pumped into the pipe body 410, ultimately producing warm water. This method is relatively convenient to use.

[0043] Specifically, heater 220 can be a heating element or heating plate, etc., and is not limited here. Water pump 230 can be a conventional fluid pump.

[0044] In this embodiment, the hot water outlet 211 is located at the bottom of the hot water bottle 210, the heater 220 is located at the bottom of the hot water bottle 210, and the hot water pump 230 is located below the hot water bottle 210, so that the water in the hot water bottle 210 can flow smoothly into the hot water pump 230 after it is fully boiled, and the drinking water device has a compact structure.

[0045] In this embodiment, the coolant supply mechanism 300 includes a cold water tank 310 and a cold water pump 320. The cold water tank 310 is provided with a cold water outlet 311 and a return port 312. The cold water outlet 311 is connected to the inlet of the cooling channel 430 through the cold water pump 320, and the return port 312 is connected to the outlet of the cooling channel 430. Cooling water in the cold water tank 310 is transported to the inlet of the cooling channel 430 by the cold water pump 320 through the cold water outlet 311. Subsequently, the cooling water flows back to the cold water tank 310 through the outlet of the cooling channel 430 and the return port 312, thereby enabling the recycling of cooling water, reducing damage to the cooling water, and saving energy and protecting the environment.

[0046] Specifically, the chilled water pump 320 can be an existing fluid pump.

[0047] In this embodiment, the coolant outlet 311 is located at the bottom of the cold water tank 310, the cold water pump 320 is located below the cold water tank 310, and the return port 312 is located at the top of the cold water tank 310, which makes the circulation of cooling water smoother and the cooling effect better.

[0048] In this embodiment, the cold water tank 310 and the hot water bottle 210 are arranged side by side, with the heat exchange section 411 and the plate 420 located between the cold water tank 310 and the hot water bottle 210, making the structure of the drinking water device more compact. It is understood that the heat exchange section 411 and the plate 420 could also be located in other positions within the drinking water device, and this is not limited here.

[0049] Specifically, the water inlet of the cooling channel 430 is connected to the cold water tank 310 via a connecting pipe, and the water outlet of the cooling channel 430 is connected to the cold water tank 310 via a connecting pipe.

[0050] Specifically, the thermos 210 is detachably connected to the base 100 via a coupler, making it convenient to directly take out the thermos 210 to fill with drinking water for boiling.
