Description

Technical Field

[0001] The utility model relates to the technical field of water dispensers, in particular to a fast water-cooled semiconductor refrigeration water dispenser refrigeration system. Background Art

[0002] The water dispenser cooling system is an important component responsible for providing cold water to the water dispenser.

[0003] Figure 1 The schematic diagram of a fast cooling semiconductor refrigerator refrigeration system in the prior art is shown. When drinking water at room temperature, the water purification component 1 and the water outlet faucet 2 are turned on to discharge water. After being filtered and purified by the water purification component 1, the municipal tap water flows through the cold end pipeline of the semiconductor refrigerator 4 and flows out from the water outlet faucet 2. Since the semiconductor refrigerator 4 is not powered on at this time, the semiconductor refrigeration sheet group does not refrigerate, so what is obtained from the water outlet faucet 2 is drinking water at room temperature.

[0004] When drinking low-temperature water is needed, the water purification component 1, the semiconductor refrigerator 4, the water tap 2, and the cooling water solenoid valve 3 are energized and work. At this time, the municipal tap water is filtered and purified by the water purification component 1 and enters the cold-end cooling water chamber 41 of the semiconductor refrigerator 4, and is cooled by the cold-end cooling heat conductive sheet 42 to become low-temperature water and flow out from the water tap 2; at the same time, the municipal tap water enters the hot-end cooling water chamber 43 of the semiconductor refrigerator 4 through the cooling water solenoid valve 3, and absorbs the heat of the hot-end heat dissipation heat conductive sheet 44, and then flows out from the upper end outlet of the semiconductor refrigerator 4 and is discharged into the sewer. In this way, low-temperature drinking water can be obtained by continuous operation.

[0005] Obviously, when drinking low-temperature water, the semiconductor refrigerator 4 of the fast-cooling water dispenser with the above-mentioned refrigeration system has to discharge cooling water when the semiconductor refrigerator 4 works, which not only causes a certain amount of water resource waste, but also the inconvenience of drainage will limit the use location of the water dispenser. Utility Model Content

[0006] The purpose of the utility model is to provide a fast water-cooled semiconductor refrigeration drinking water machine refrigeration system, aiming to at least solve the technical problems existing in the above-mentioned prior art. To achieve the above-mentioned purpose, the technical solutions adopted by the utility model are as follows:

[0007] The utility model proposes a fast water-cooled semiconductor refrigeration drinking water machine refrigeration system, including a water purification pump, a water purification component, a semiconductor refrigerator, a raw water tank, a cooling water pump, a cooling water return pipe, a water outlet faucet and a heat dissipation component;

[0008] Wherein, the water purification pump is arranged between the water inlet end of the water purification component and the No. 1 water inlet of the raw water tank;

[0009] Wherein, the water outlet of the water purification component is connected to the drinking water inlet of the semiconductor refrigerator;

[0010] Wherein, the drinking water outlet of the semiconductor refrigerator is connected to the water outlet faucet;

[0011] Wherein, the cooling water pump is arranged between the No. 1 water inlet of the raw water tank and the cooling water inlet of the semiconductor refrigerator;

[0012] Wherein, the cooling water return pipe is connected between the cooling water outlet of the semiconductor refrigerator and the heat dissipation water inlet of the heat dissipation component;

[0013] Wherein, the heat dissipation outlet of the heat dissipation component is connected to the No. 2 water outlet of the raw water tank.

[0014] As a further solution of the utility model: the heat dissipation component includes a fin-tube heat exchanger, the heat dissipation water inlet of the fin-tube heat exchanger is connected to the end of the cooling water return pipe away from the semiconductor refrigerator, and the heat dissipation water outlet of the fin-tube heat exchanger is connected to the No. 2 water outlet of the raw water tank.

[0015] As a further solution of the utility model: the raw water tank has an upper water storage chamber and a lower heat dissipation chamber, an air inlet is opened at the bottom of the lower heat dissipation chamber, and an air outlet is opened at the side of the lower heat dissipation chamber.

[0016] As a further solution of the utility model: the No. 1 water inlet and the No. 2 water inlet are arranged at the top of the lower heat dissipation chamber and are connected to the upper water storage chamber, and the fin tube heat exchanger is arranged in the lower heat dissipation chamber and is located directly above the air inlet.

[0017] As a further solution of the utility model: the heat dissipation component also includes a cooling electric fan, and the cooling electric fan is arranged in the lower heat dissipation chamber and directly faces the air outlet.

[0018] As a further solution of the utility model: the semiconductor refrigerator has a cold-end refrigeration water chamber, a cold-end refrigeration heat conductive sheet, a hot-end cooling water chamber and a hot-end heat dissipation heat conductive sheet, the cold-end refrigeration heat conductive sheet is connected to the hot-end heat dissipation heat conductive sheet by a heat conductor, the cold-end refrigeration water chamber is arranged on the cold-end refrigeration heat conductive sheet, and the hot-end cooling water chamber is arranged on the hot-end heat dissipation heat conductive sheet.

[0019] As a further solution of the utility model: the drinking water inlet and the drinking water outlet are both arranged on the cold-end refrigeration water chamber; the cooling water inlet and the cooling water outlet are both arranged on the hot-end cooling water chamber.

[0020] The utility model proposes a fast water-cooled semiconductor refrigeration drinking water machine refrigeration system, which includes at least the following two working modes:

[0021] Mode 1: Producing normal temperature drinking water

[0022] In this mode, the water purification pump, water purification component and water outlet faucet work. The water purification pump draws raw tap water from the raw water tank and sends it to the water purification component. The raw tap water is filtered and purified by the water purification component and then enters the semiconductor refrigerator from the drinking water inlet. Finally, it flows from the drinking water outlet to the water outlet faucet. What flows out of the water outlet faucet is only purified drinking water at room temperature.

[0023] Mode 2: Producing low-temperature drinking water

[0024] In this mode, the refrigeration system works normally. The water purification pump draws raw tap water from the raw water tank and sends it to the water purification component. The raw tap water enters the semiconductor refrigerator from the drinking water inlet after being filtered and purified by the water purification component. After the semiconductor refrigerator absorbs heat and cools, it becomes low-temperature drinking water. The low-temperature drinking water flows out from the drinking water outlet through the water outlet faucet.

[0025] At the same time, the cooling water pump draws tap water from the raw water tank and sends it into the semiconductor refrigerator from the cooling water inlet. This part of the tap water absorbs the heat in the semiconductor refrigerator and then flows out from the cooling water outlet, enters the heat dissipation component through the cooling water return pipe to dissipate part of the heat and then enters the raw water tank.

[0026] When the low-temperature drinking water is stopped, the semiconductor refrigerator, water purification pump, water purification component and water outlet faucet stop working, and the cooling water pump and heat dissipation component continue to work, and the tap water in the raw water tank and the semiconductor refrigerator continue to be cooled until the raw water temperature in the raw water tank is lower than the preset value and stops working.

[0027] Compared with the prior art, the utility model has at least the following beneficial effects:

[0028] The utility model sets up a fast water-cooled semiconductor refrigeration water dispenser refrigeration system, and the raw water volume of the tap water in the raw water tank is much larger than the amount of low-temperature drinking water taken each time. The tap water in the raw water tank is used to temporarily store the heat generated when the semiconductor refrigerator is working, and the water in the raw water tank is cooled for a long time by setting a heat dissipation component. Since the time of drinking low-temperature cold water is much shorter than the time of not drinking low-temperature cold water, the working time of the semiconductor refrigerator is much shorter than the downtime. Therefore, the heat generated by the semiconductor refrigerator can be dissipated and cooled for a long time through the heat dissipation component. The refrigeration system not only saves water resources, but also realizes the rapid refrigeration function on the water-adding countertop water dispenser, which greatly expands the application scenarios of the rapid refrigeration function and is completely suitable for places such as living rooms, rooms and offices.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Therefore, it should not be understood as a limitation on the present invention.

[0036] In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0037] Figure 1A fast cooling semiconductor refrigerator refrigeration system in the prior art is shown. When low-temperature water is needed for drinking, the water purification component 1, the semiconductor refrigerator 4, the water tap 2, and the cooling water solenoid valve 3 are powered on and work. The municipal tap water is filtered and purified by the water purification component 1 and enters the cold-end cooling water chamber 41 of the semiconductor refrigerator 4, and is cooled by the cold-end cooling heat conductive sheet 42 to become low-temperature water and flow out from the water tap 2; at the same time, the municipal tap water enters the hot-end cooling water chamber 43 of the semiconductor refrigerator 4 through the cooling water solenoid valve 3, and absorbs the heat of the hot-end heat dissipation heat conductive sheet 44, and then flows out from the upper end outlet of the semiconductor refrigerator 4 and is discharged into the sewer. In this way, low-temperature drinking water can be obtained by continuous operation.

[0038] Obviously, when preparing drinking low-temperature water, the semiconductor refrigerator 4 works and needs to discharge cooling water, which not only causes a certain amount of water resource waste, but also the inconvenience of drainage will limit the use location of the water dispenser, making it unsuitable for use in living rooms, rooms, offices and other places.

[0039] Based on this, the embodiment of the utility model provides a fast water-cooled semiconductor refrigeration drinking water machine refrigeration system, which may at least include a clean water pump 5, a water purification component 1, a semiconductor refrigerator 4, a raw water tank 6, a cooling water pump 7, a cooling water return pipe 8, a water outlet faucet 2 and a heat dissipation component 9. Among them, the clean water pump 5 is arranged between the water inlet end of the water purification component 1 and the No. 1 water inlet 61 of the raw water tank 6, and the clean water pump 5 is used to extract the tap water in the raw water tank 6 from the No. 1 water inlet 61 and send it into the water purification component 1; the water outlet end of the water purification component 1 is connected to the drinking water inlet 45 of the semiconductor refrigerator 4, and the water purification component 1 is used to filter and purify the tap water to obtain normal temperature drinking water; the drinking water outlet 46 of the semiconductor refrigerator 4 is connected to the water outlet faucet 2, and the semiconductor refrigerator 4 is used to endothermally cool the normal temperature drinking water; the cooling water pump 7 is arranged between the No. 1 water inlet 61 of the raw water tank 6 and the cooling water inlet 47 of the semiconductor refrigerator 4; The pipe 8 is connected between the cooling water outlet 48 of the semiconductor refrigerator 4 and the heat dissipation inlet of the heat dissipation component 9; the heat dissipation outlet of the heat dissipation component 9 is connected with the No. 2 water inlet 62 of the raw water tank 6, and the cooling water pump 7 is used to extract the tap water in the raw water tank 6 from the No. 1 water inlet 61 and send it to the cooling water inlet 47. This part of the tap water enters the semiconductor refrigerator 4 and quickly absorbs the heat in the semiconductor refrigerator 4 to cool the semiconductor refrigerator 4. The tap water that has absorbed the heat flows into the cooling water return pipe 8 from the cooling water outlet 48, and finally flows back to the raw water tank 6 from the No. 2 water inlet 62 after dissipating the heat from the cooling water return pipe 8 through the heat dissipation component 9.

[0040] According to analysis, drinking low-temperature water is intermittent in places such as living rooms, rooms and offices. The raw water volume of the tap water in the raw water tank 6 of the water-adding countertop water dispenser with the refrigeration system is much larger than the amount of low-temperature drinking water taken each time. The tap water in the raw water tank 6 of the water-adding countertop water dispenser is used to temporarily store the heat generated by the semiconductor refrigerator 4 when it is working, and the water in the raw water tank 6 is cooled for a long time by setting the heat dissipation component 9. Since the time of drinking low-temperature cold water is much shorter than the time of not drinking low-temperature cold water, the working time of the semiconductor refrigerator 4 is much shorter than the downtime. Therefore, the heat generated by the semiconductor refrigerator 4 is cooled for a long time through the heat dissipation component 9. The technical solution is feasible. The refrigeration system not only saves water resources, but also realizes the rapid cooling function on the water-adding countertop water dispenser, greatly expanding the application scenarios of the rapid cooling function, and is completely suitable for places such as living rooms, rooms and offices.

[0041] See also Figure 2 As shown, in one embodiment, the raw water tank 6 has an upper water storage chamber 63 and a lower heat dissipation chamber 64, an air inlet 65 is provided at the bottom of the lower heat dissipation chamber 64, and an air outlet 66 is provided at the side of the lower heat dissipation chamber 64, so as to realize the heat dissipation cycle in the lower heat dissipation chamber 64. The heat dissipation assembly 9 includes a fin tube heat exchanger 91, the heat dissipation water inlet of the fin tube heat exchanger 91 is connected to the end of the cooling water return pipe 8 away from the semiconductor refrigerator 4, and the heat dissipation water outlet of the fin tube heat exchanger 91 is connected to the No. 2 water inlet 62 of the raw water tank 6, the No. 1 water inlet 61 and the No. 2 water inlet 62 are arranged at the top of the lower heat dissipation chamber 64 and are connected to the upper water storage chamber 63, and the fin tube heat exchanger 91 is arranged in the lower heat dissipation chamber 64 and is located directly above the air inlet 65. The tap water raw water that absorbs the heat of the semiconductor refrigerator 4 flows from the cooling water return pipe 8 into the fin tube heat exchanger 91 to dissipate part of the heat first, and then flows into the raw water tank 6 from the No. 2 water inlet 62.

[0042] Furthermore, the heat dissipation component 9 also includes a cooling electric fan 92 . The cooling electric fan 92 is disposed in the lower heat dissipation chamber 64 and directly faces the air outlet 66 . The cooling electric fan 92 can continuously dissipate heat for the raw water tank 6 .

[0043] See also Figure 2 As shown, in one embodiment, the semiconductor refrigerator 4 has a cold end cooling water chamber 41, a cold end cooling heat conductive sheet 42, a hot end cooling water chamber 43 and a hot end heat dissipation heat conductive sheet 44, the cold end cooling heat conductive sheet 42 and the hot end heat dissipation heat conductive sheet 44 are connected by a heat conductor, the cold end cooling water chamber 41 is arranged on the cold end cooling heat conductive sheet 42, and the hot end cooling water chamber 43 is arranged on the hot end heat dissipation heat conductive sheet 44. Among them, the drinking water inlet 45 and the drinking water outlet 46 are both arranged on the cold end cooling water chamber 41; the cooling water inlet 47 and the cooling water outlet 48 are both arranged on the hot end cooling water chamber 43.

[0044] The room-temperature drinking water obtained after purification enters the cold-end refrigeration water chamber 41 from the drinking water inlet 45, and the cold-end refrigeration heat conducting sheet 42 absorbs the heat of the room-temperature drinking water in the cold-end refrigeration water chamber 41, so that it is quickly cooled to obtain low-temperature drinking water, and the low-temperature drinking water then flows out from the drinking water outlet 46. In this process, the cooling water pump 7 draws the tap water from the raw water tank 6 and sends it into the hot-end cooling water chamber 43 from the cooling water inlet 47. The tap water in the hot-end cooling water chamber 43 absorbs the heat of the hot-end heat dissipating sheet 44. The heat on the hot-end heat dissipating sheet 44 comes from the heat transferred by the cold-end refrigeration heat conducting sheet 42. The tap water in the hot-end cooling water chamber 43 that has absorbed the heat flows into the cooling water return pipe 8 from the cooling water outlet 48, and circulates from the cooling water return pipe 8 to the fin-tube heat exchanger 91, and flows back to the raw water tank 6 after preliminary heat dissipation in the fin-tube heat exchanger 91.

[0045] On the other hand, the embodiment of the utility model also proposes a working method of a fast water-cooled semiconductor refrigeration water machine refrigeration system, which includes at least the following two modes:

[0046] Mode 1: Producing normal temperature drinking water

[0047] In this mode, the water purification pump 5, the water purification component 1 and the water outlet faucet 2 are working. The water purification pump 5 draws raw tap water from the raw water tank 6 and sends it into the water purification component 1. The raw tap water is filtered and purified by the water purification component 1 and then enters the semiconductor refrigerator 4 from the drinking water inlet 45, and finally flows from the drinking water outlet 46 to the water outlet faucet 2. What flows out of the water outlet faucet 2 is only purified drinking water at room temperature.

[0048] Mode 2: Producing low-temperature drinking water

[0049] In this mode, the refrigeration system works normally. The water purification pump 5 extracts the tap water in the raw water tank 6 and sends it to the water purification component 1. The tap water enters the cold end refrigeration water chamber 41 of the semiconductor refrigerator 4 from the drinking water inlet 45 after being filtered and purified by the water purification component 1. After absorbing heat and cooling by the cold end refrigeration heat conducting sheet 42 of the semiconductor refrigerator 4, it becomes low-temperature drinking water. The low-temperature drinking water flows out from the drinking water outlet 46 through the water outlet faucet 2.

[0050] At the same time, the cooling water pump 7 draws the tap water in the raw water tank 6 and sends it into the hot end cooling water chamber 43 of the semiconductor refrigerator 4 through the cooling water inlet 47. The tap water in the hot end cooling water chamber 43 absorbs the heat transferred from the cold end refrigeration heat conductive plate 42 to the hot end heat dissipation heat conductive plate 44, and then flows out from the cooling water outlet 48, enters the heat dissipation component 9 through the cooling water return pipe 8 to dissipate part of the heat, and then enters the raw water tank 6.

[0051] It should be noted that when producing low-temperature drinking water, in order to obtain the function of quickly producing low-temperature water, the cooling power of the semiconductor refrigerator 4 is designed to be relatively large, generally around 1500W or more, and the heat brought out by the cooling water during operation is relatively large. However, due to the limited structural size of the countertop water purifier, the heat dissipation of the designed air-cooled fin-tube heat exchanger 91 and the cooling fan 92 is far less than 1500W. Therefore, when producing low-temperature drinking water, the temperature of the tap water in the raw water tank 6 continues to rise as the working time increases.

[0052] In order to solve this problem, when the low-temperature drinking water is stopped, the semiconductor refrigerator 4, the water purification pump 5, the water purification component 1 and the water outlet faucet 2 stop working, and the cooling water pump 7 and the heat dissipation component 9 continue to work, and the tap water in the raw water tank 6 and the semiconductor refrigerator 4 continue to be cooled down until the raw water temperature in the raw water tank is lower than the preset value and stops working.

[0053] The utility model cleverly utilizes the fact that the amount of raw water in the raw water tank 6 is much larger than the amount of low-temperature drinking water used each time and that the use of low-temperature drinking water is intermittent. The larger volume of raw water in the raw water tank 6 is used to temporarily store the heat released by the semiconductor refrigerator 4 for a short time. A high-efficiency air-cooled fin-tube heat exchanger 91 and a cooling electric fan 92 are designed to cool the raw water in the raw water tank 6 through long-term heat dissipation, thereby achieving a stable total heat of the raw water in the raw water tank 6, solving the problem of short-term high-power heat dissipation difficulty of the semiconductor refrigerator 4, realizing the rapid cooling function of the water-adding countertop water purifier, and saving water resources.

[0054] The above detailed description of the preferred embodiments of the utility model should not be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
