Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a refrigeration liner and a drinking water device containing the refrigeration liner. Background Art

[0002] As people's quality of life improves, the purification and heating functions of drinking water devices can no longer meet people's water needs. At present, drinking water devices with cold water functions, or with purification, heating and cold water functions, have appeared on the market.

[0003] The realization of the cold water function is inseparable from the refrigeration module. At present, a common refrigeration module is the refrigeration tank, which has a simple structure and low cost. However, the common problem of the existing refrigeration tank is that the refrigeration speed is slow due to poor heat dissipation, which makes the refrigeration temperature not meet the standard; in addition, the problem of poor heat dissipation will also lead to an increase in the failure rate of the refrigeration tank. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect of poor heat dissipation of a refrigeration liner in the prior art, and to provide a refrigeration liner and a drinking water device containing the refrigeration liner.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A refrigeration liner comprises: a refrigeration liner body, a refrigeration assembly and a liquid cooling component; a refrigeration cavity is formed inside the refrigeration liner body; two ends of the refrigeration assembly are respectively a cold end and a hot end, the cold end of the refrigeration assembly extends into the interior of the refrigeration cavity, and the hot end of the refrigeration assembly is located outside the refrigeration cavity; the interior of the liquid cooling component is used to accommodate a liquid medium; the liquid cooling component is in contact with the hot end of the refrigeration assembly to cool the hot end of the refrigeration assembly.

[0007] In this solution, the refrigeration cavity inside the refrigeration tank body is the main place for cooling the water flow. The cold end of the refrigeration component extends into the refrigeration cavity, absorbs the heat of the water flow and cools the water flow. The heat absorbed by the cold end is then dissipated through the hot end located outside the refrigeration cavity (by air cooling). The liquid cooling component inside for accommodating the liquid medium is attached to the hot end. A liquid medium with a lower temperature is added to the liquid cooling component. Since the temperature of the liquid medium in the liquid cooling component is lower than the temperature of the hot end of the refrigeration component, the hot end can be cooled through heat exchange, which speeds up the heat dissipation speed of the hot end of the refrigeration component, thereby improving the heat dissipation efficiency of the refrigeration tank.

[0008] Preferably, the refrigeration component includes a refrigeration device, a heat exchanger and a radiator; the heat exchanger is located inside the refrigeration cavity to form a cold end of the refrigeration component; the radiator is located outside the refrigeration cavity to form a hot end of the refrigeration component; the refrigeration device is connected between the heat exchanger and the radiator; the radiator is formed with a accommodating cavity, and at least part of the liquid cooling component is arranged in the accommodating cavity.

[0009] In this solution, the heat exchanger is located inside the refrigeration chamber to facilitate heat exchange with the water flow; the refrigeration device is connected between the heat exchanger and the radiator, and is used to reduce the temperature of the heat exchanger itself to reduce the temperature of the water flow on the one hand, and to transfer the heat generated by the refrigeration process to the radiator and dissipate it through the radiator on the other hand. The radiator is formed with a receiving cavity, and at least part of the liquid cooling component is arranged in the receiving cavity. Not only does the receiving cavity provide a physical basis for the installation and setting of the liquid cooling component, but the form of the receiving cavity also increases the contact area between the liquid cooling component and the radiator, thereby improving the cooling effect of the radiator; in addition, the formation of the receiving cavity on the radiator avoids the liquid cooling component from occupying additional installation space, thereby improving the compactness of the overall structure of the refrigeration liner.

[0010] Preferably, the accommodating cavity is located on a side of the radiator close to the refrigeration device.

[0011] In the present solution, the temperature of the part of the radiator that is closer to the refrigeration device is higher. The accommodating chamber is opened on the side of the radiator close to the refrigeration device. The temperature difference between the liquid-cooling component and the radiator is large, which is conducive to the liquid-cooling component to cool the radiator in time and fully. Moreover, since the accommodating chamber is close to the side of the refrigeration device, the liquid-cooling component can also produce a certain cooling effect on the refrigeration device.

[0012] Preferably, the accommodating cavity is provided with an opening; the liquid cooling component is attached to the refrigeration device through the opening.

[0013] In this solution, the liquid cooling component can fit with the refrigeration device through the opening, so that the liquid cooling component can also directly cool the refrigeration device.

[0014] A drinking water device comprises the refrigeration liner as described above; the liquid cooling component comprises a liquid inlet, a liquid outlet and a body, and the liquid inlet and the liquid outlet are respectively connected to the interior of the body.

[0015] In the present scheme, the drinking water device including the refrigeration liner as described above can cool the hot end of the refrigeration component through the liquid cooling component, accelerate the heat dissipation speed of the hot end of the refrigeration component, thereby improving the heat dissipation efficiency of the refrigeration liner, making the refrigeration temperature of the drinking water device meet the standard, and reducing the failure rate of the drinking water device; in addition, the liquid cooling component includes a main body and a liquid inlet and a liquid outlet respectively connected to the interior of the main body, so that the liquid medium in the liquid cooling component can flow. On the one hand, the liquid medium can be continuously replenished through the liquid inlet to improve the cooling effect of the liquid cooling component, and on the other hand, the heated liquid medium can be drawn out through the liquid outlet and utilized.

[0016] Preferably, the drinking water device also includes a first pipeline and a heating element; one end of the first pipeline is connected to the liquid outlet of the liquid cooling component, and the other end of the first pipeline forms a first user end; the heating element is arranged on the first pipeline.

[0017] In this solution, the liquid medium in the liquid cooling component absorbs heat and rises in temperature before flowing out from the liquid outlet. Afterwards, the liquid medium flows into the first pipeline, is heated by the heating element, and flows out from the first user end for use by the user. Since the liquid medium has been heated to a certain extent after passing through the liquid cooling component, it is equivalent to being preheated before the heating element heats the liquid medium, thereby speeding up the heating efficiency of the liquid medium. That is, the liquid cooling component can not only improve the heat dissipation efficiency of the refrigeration tank, but also speed up the heating efficiency of the liquid medium, and the overall efficiency of the drinking water device is better.

[0018] Preferably, a first switch valve is also provided on the first pipeline; the first switch valve is located between the liquid outlet and the heating element; the drinking water device also includes a second pipeline connected to the first pipeline; the connection point between the second pipeline and the first pipeline is located between the liquid outlet and the first switch valve; and a second switch valve is provided on the second pipeline.

[0019] In this solution, the first switch valve or the second switch valve can be opened according to actual needs: when the second switch valve is closed and the first switch valve is opened, the liquid medium can be used by the user after heat exchange in the liquid cooling component and heating by the heating element; when the second switch valve is opened and the first switch valve is closed, the heated liquid medium in the liquid cooling component will be discharged through the second pipeline to promote the flow of new, lower temperature liquid medium into the liquid inlet, thereby increasing the cooling efficiency of the liquid cooling component.

[0020] Preferably, the heating element includes a first heating part and a second heating part; the first heating part and the second heating part are connected in series along the extension direction of the first pipeline, and the first heating part is located on a side of the second heating part away from the first user end.

[0021] In this solution, by providing two first heating parts and second heating parts connected in series, the power is greater and the heating effect is better.

[0022] Preferably, the drinking water device also includes a third pipeline; one end of the third pipeline is connected to the first heating part, and the other end of the third pipeline is connected to the liquid inlet of the liquid cooling component; a circulation part is arranged on the third pipeline to form a circulation pipeline between the third pipeline and the first pipeline.

[0023] In this solution, a circulation component is arranged on the third pipeline to form a circulation pipeline between the third pipeline and the first pipeline. As a result, the liquid medium heated by the liquid cooling component can enter the liquid cooling component again through the third pipeline after passing through the first heating part, so that the first heating part can heat the liquid medium multiple times to improve efficiency; at the same time, the utilization rate of the liquid medium is improved to avoid waste.

[0024] Preferably, the drinking water device also includes a water purification component, a fourth pipeline and a fifth pipeline; the water purification component includes a first water inlet, a clean water outlet and a waste water outlet; the cold tank body is provided with a second water inlet and a water outlet respectively connected to the refrigeration chamber; one end of the fourth pipeline is connected to the clean water outlet, and the other end of the fourth pipeline forms a second user end; one end of the fifth pipeline is connected to the clean water outlet, and the other end of the fifth pipeline is connected to the second water inlet; the waste water outlet is connected to the liquid inlet.

[0025] In this solution, water flows into the water purification component from the first water inlet, and the purified water flows out from the water purification outlet and is divided into two paths. One path flows out from the fourth pipeline to the second user end for direct drinking by the user; the other path flows from the fifth pipeline through the second water inlet into the cooling tank body for cooling, and then the cold water flows out from the water outlet. The wastewater generated after the purification component purifies the water flows flows out from the wastewater outlet and enters the liquid cooling component through the liquid inlet, that is, the wastewater is used to cool the cooling tank (the cooling component), thereby improving the water flow utilization rate of the drinking water device.

[0026] The positive and progressive effects of the utility model are:

[0027] In the present invention, the refrigeration cavity inside the refrigeration tank body is the main place for cooling the water flow. The cold end of the refrigeration component extends into the refrigeration cavity to absorb the heat of the water flow and cool the water flow. The heat absorbed by the cold end is then dissipated through the hot end located outside the refrigeration cavity (by air cooling). Since the liquid cooling component used to accommodate the liquid medium is attached to the hot end, by adding a liquid with a lower temperature into the liquid cooling component, the hot end of the refrigeration component can be cooled by the liquid cooling component, accelerating the heat dissipation speed of the hot end of the refrigeration component, thereby improving the heat dissipation efficiency of the refrigeration tank.

[0076] The present invention will be described more clearly and completely below through embodiments in conjunction with the accompanying drawings.

[0077] Example 1

[0078] like Figure 1 , Figure 6-Figure 10As shown, this embodiment provides a drinking water device, including a refrigeration tank 100, a water purification component 700, a fourth pipeline 800 and a fifth pipeline 820.

[0079] The refrigeration liner 100 includes: a refrigeration liner body 110, a refrigeration assembly 120 and a liquid cooling component 130; a refrigeration cavity 114 is formed inside the refrigeration liner body 110; the two ends of the refrigeration assembly 120 are respectively a cold end and a hot end, the cold end of the refrigeration assembly 120 extends into the interior of the refrigeration cavity 114, and the hot end of the refrigeration assembly 120 is located outside the refrigeration cavity 114; the interior of the liquid cooling component 130 is used to accommodate a liquid medium; the liquid cooling component 130 is attached to the hot end of the refrigeration assembly 120 to cool the hot end of the refrigeration assembly 120.

[0080] The refrigeration cavity 114 inside the refrigeration tank body 110 is the main place for cooling the water flow. The cold end in the refrigeration component 120 extends into the refrigeration cavity 114 to absorb the heat of the water flow and cool the water flow. The heat absorbed by the cold end is then dissipated through the hot end located outside the refrigeration cavity 114 (by air cooling). The liquid cooling component 130 for accommodating the liquid medium is attached to the hot end. By adding a liquid medium with a lower temperature into the liquid cooling component 130, since the temperature of the liquid medium in the liquid cooling component 130 is lower than the temperature of the hot end of the refrigeration component 120, the hot end of the refrigeration component 120 can be cooled through heat exchange, and the heat dissipation speed of the hot end of the refrigeration component 120 is accelerated, thereby improving the heat dissipation efficiency of the refrigeration tank 100.

[0081] In this embodiment, the refrigeration component 120 includes a refrigeration device 121, a heat exchanger 122 and a radiator 123; the heat exchanger 122 is located inside the refrigeration cavity 114 to form a cold end of the refrigeration component 120; the radiator 123 is located outside the refrigeration cavity 114 to form a hot end of the refrigeration component 120; the refrigeration device 121 is connected between the heat exchanger 122 and the radiator 123; the radiator 123 is formed with a accommodating cavity 124, and at least part of the liquid cooling component 130 is arranged in the accommodating cavity 124.

[0082] The heat exchanger 122 is located inside the refrigeration chamber 114 so as to exchange heat with the water flow; the refrigeration device 121 is connected between the heat exchanger 122 and the radiator 123, and is used to reduce the temperature of the heat exchanger 122 itself to reduce the temperature of the water flow on the one hand, and to transfer the heat generated by the refrigeration process to the radiator 123 and dissipate it through the radiator 123 on the other hand. The radiator 123 is formed with a receiving chamber 124, and at least part of the liquid cooling component 130 is arranged in the receiving chamber 124. Not only does the receiving chamber 124 provide a physical basis for the installation and setting of the liquid cooling component 130, but the form of the receiving chamber 124 also increases the contact area between the liquid cooling component 130 and the radiator 123, thereby improving the cooling effect of the radiator 123; in addition, the receiving chamber 124 is formed on the radiator 123 to avoid the liquid cooling component 130 from occupying additional installation space, thereby improving the compactness of the overall structure of the refrigeration liner 100.

[0083] like Figure 6 As shown, the radiator 123 in this embodiment adopts a plate structure to increase the contact area with the air; in order to further enhance the air cooling effect, a fan 126 is also installed outside the radiator 123.

[0084] The refrigeration device 121 is an existing structure and will not be described in detail.

[0085] Specifically, the accommodating cavity 124 is located at a side of the radiator 123 close to the refrigeration device 121 .

[0086] The temperature of the part of the radiator 123 that is closer to the refrigeration device 121 is higher. The accommodating chamber 124 is opened on the side of the radiator 123 close to the refrigeration device 121. The temperature difference between the liquid cooling component 130 and the radiator 123 is large, which is beneficial for the liquid cooling component 130 to cool the radiator 123 in time and fully. Moreover, since the accommodating chamber 124 is close to the side of the refrigeration device 121, the liquid cooling component 130 can also produce a certain cooling effect on the refrigeration device 121.

[0087] The specific structure of the liquid cooling component 130 can be selected in many ways, such as Figure 8 As shown, in this embodiment, the liquid cooling component 130 is a box-shaped structure with a simple structure and a large capacity. To match it, the accommodating cavity 124 can be set as a whole through groove or blind groove inside the radiator 123; Fig.10 As shown, the liquid cooling component 130 can also be set as a multi-section folded tubular structure, which has a larger specific surface area and a better heat exchange effect. To match this, the accommodating cavity 124 can be set as a row of through-hole structures inside the radiator 123.

[0088] like Fig. 9As shown, the accommodating cavity 124 may further be provided with an opening 125 , and the liquid cooling component 130 is attached to the refrigeration device 121 through the opening 125 , so that the liquid cooling component 130 can directly cool the refrigeration device 121 .

[0089] Understandably, Fig. 9 The opening 125 shown in the figure is opened on the side of the accommodating chamber 124 close to the refrigerating device 121 (or the cooling tank body 110), and is realized by eliminating the wall surface of the accommodating chamber 124 close to the refrigerating device 121. In other optional embodiments, the opening 125 can also be opened at any position of the accommodating chamber 124 according to actual conditions, and the liquid cooling component 130 and the refrigerating device 121 can be made to fit together by changing the structure and setting position of the liquid cooling component 130 and the refrigerating device 121.

[0090] Furthermore, the liquid cooling component 130 includes a liquid inlet 131, a liquid outlet 132 and a main body 133. The liquid inlet 131 and the liquid outlet 132 are respectively connected to the interior of the main body 133, so that the liquid medium in the liquid cooling component 130 can flow. On the one hand, the liquid medium can be continuously replenished through the liquid inlet 131 to improve the cooling effect of the liquid cooling component 130. On the other hand, the heated liquid medium can also be drawn out through the liquid outlet 132 and utilized.

[0091] The cooling tank body 110 is provided with a second water inlet 111 and a water outlet 112 which are respectively connected to the refrigeration chamber 114, so that the water to be cooled can enter the refrigeration chamber 114 and flow out from the water outlet 112 after cooling for use by users.

[0092] In addition, the refrigeration tank body 110 is also provided with a drain port 113 communicating with the refrigeration chamber 114 so that the water in the refrigeration chamber 114 can be drained during maintenance and inspection. When the refrigeration tank 100 operates normally, the drain port 113 is closed.

[0093] like Figure 1 As shown, the water purification assembly 700 includes a first water inlet 710 , a purified water outlet 720 , and a waste water outlet 730 .

[0094] One end of the fourth pipeline 800 is in communication with the purified water outlet 720 , and the other end of the fourth pipeline 800 forms a second user end 810 .

[0095] One end of the fifth pipeline 820 is connected to the clean water outlet 720 , and the other end of the fifth pipeline 820 is connected to the second water inlet 111 ; the waste water outlet 730 is connected to the liquid inlet 131 .

[0096] Through the above-mentioned connection method, water flows into the water purification component 700 from the first water inlet 710, and the purified water flows out from the water purification outlet 720 and is divided into two paths. One path flows out from the fourth pipeline 800 to the second user end 810 for direct drinking by the user; the other path flows from the fifth pipeline 820 through the second water inlet 111 into the refrigeration chamber 114 in the cold tank body 110 for cooling, and then the cold water flows out from the water outlet 112 to meet the user's diverse needs for drinking water temperature.

[0097] It can be understood that in order to control the on-off of the fourth pipeline 800 and the fifth pipeline 820, solenoid valves 902 can be respectively set on the fourth pipeline 800 and the fifth pipeline 820 to allow users to choose between normal temperature pure water and low temperature pure water; in order to provide power for the flow of water, a pump 620 can be further set outside the water outlet 112 of the cold tank body 110 or on other pipelines.

[0098] The wastewater generated after the purification component purifies the water flow flows out from the wastewater outlet 730, enters the main body 133 of the liquid cooling component 130 through the liquid inlet 131, and cools the refrigeration liner 100 (the refrigeration component 120) through the wastewater, thereby accelerating the heat dissipation speed of the hot end of the refrigeration component 120, thereby improving the heat dissipation efficiency of the refrigeration liner 100, making the refrigeration temperature of the drinking water device meet the standard, and reducing the failure rate of the drinking water device.

[0099] In addition, this embodiment makes full use of wastewater, using wastewater as the liquid cooling medium in the liquid cooling component 130, thereby improving the utilization rate of the overall water flow of the drinking water device; in other optional implementations, other types of liquids can also be selected as liquid cooling media.

[0100] Example 2

[0101] In this embodiment, the structure of the refrigeration liner 100 is the same as that in Embodiment 1, and the difference from Embodiment 1 is that:

[0102] like Figure 2 As shown, the drinking water device also includes a first pipeline 200 and a heating element 300 ; one end of the first pipeline 200 is connected to the liquid outlet 132 of the liquid cooling component 130 , and the other end of the first pipeline 200 forms a first user end 210 ; the heating element 300 is arranged on the first pipeline 200 .

[0103] Thus, the liquid medium in the liquid cooling component 130 absorbs heat and rises in temperature before flowing out from the liquid outlet 132 . Thereafter, the liquid medium flows into the first pipeline 200 , is heated by the heating element 300 , and flows out from the first user end 210 for use by the user.

[0104] Since the liquid medium has been heated to a certain extent after passing through the liquid cooling component 130, it is equivalent to being preheated before the heating element 300 heats the liquid medium, thereby accelerating the heating efficiency of the liquid medium and increasing the flow rate of the heated liquid medium flowing out of the first user end 210. Therefore, the liquid cooling component 130 can not only improve the heat dissipation efficiency of the refrigeration liner 100, but also accelerate the heating efficiency of the liquid medium, and the overall effect of the drinking water device is better.

[0105] In addition, the liquid inlet 131 of the liquid cooling component 130 in this embodiment can be connected to the wastewater outlet 730 as in Example 1, so that the wastewater can be heated and used as non-drinking hot water; however, as part of a drinking water device, the liquid inlet 131 of the liquid cooling component 130 is better to flow in ordinary water flow (that is, ordinary water flow is used as the liquid cooling medium), and after heat exchange and temperature rise in the liquid cooling component 130 and then heating by the heating element 300, hot water for the user to drink flows out from the first user end 210.

[0106] Of course, in this embodiment, the water purification component 700 and the fourth pipeline 800 may not be provided, one end of the fifth pipeline 820 is connected to the second water inlet 111 of the refrigeration tank body 110, and the other end of the fifth pipeline 820 may flow into ordinary water.

[0107] Furthermore, if Figure 3 As shown, a first switch valve 220 may also be provided on the first pipeline 200; the first switch valve 220 is located between the liquid outlet 132 and the heating element 300; the drinking water device also includes a second pipeline 400 connected to the first pipeline 200; the connection point between the second pipeline 400 and the first pipeline 200 is located between the liquid outlet 132 and the first switch valve 220; a second switch valve 410 is provided on the second pipeline 400.

[0108] Thus, the first switch valve 220 or the second switch valve 410 can be opened according to actual needs: when the second switch valve 410 is closed and the first switch valve 220 is opened, the liquid medium can be used by the user after heat exchange through the liquid cooling component 130 and heating by the heating element 300; when the second switch valve 410 is opened and the first switch valve 220 is closed, the heated liquid medium in the liquid cooling component 130 will be discharged through the second pipeline 400 to promote the flow of new, lower temperature liquid medium into the liquid inlet 131, thereby increasing the cooling efficiency of the liquid cooling component 130.

[0109] The heating element 300 may use an existing heating device such as a heating tube; in addition, in order to better monitor temperature changes and adjust the heating temperature of the heating element 300 , a temperature sensor 901 may be provided upstream and downstream of the heating element 300 on the first pipeline 200 .

[0110] Example 3

[0111] The structure of the drinking water device of this embodiment is basically the same as that of the embodiment 2, and the difference from the embodiment 2 is that:

[0112] like Figure 4 As shown, in this embodiment, the heating element 300 includes a first heating part 310 and a second heating part 320; the first heating part 310 and the second heating part 320 are connected in series along the extension direction of the first pipeline 200, and the first heating part 310 is located on the side of the second heating part 320 away from the first user end 210.

[0113] By providing two first heating parts 310 and second heating parts 320 connected in series, the power is greater and the heating effect is better.

[0114] In this embodiment, the first heating part 310 is configured as a preheating tank with a certain water storage capacity, and the second heating part 320 is configured as a heating pipe.

[0115] Furthermore, if Figure 5 As shown, the drinking water device can also include a third pipeline 500; one end of the third pipeline 500 is connected to the first heating part 310, and the other end of the third pipeline 500 is connected to the liquid inlet 131; a circulation part is arranged on the third pipeline 500 to form a circulation pipeline between the third pipeline 500 and the first pipeline 200.

[0116] By arranging a circulation part on the third pipeline 500, a circulation pipeline is formed between the third pipeline 500 and the first pipeline 200, so that the liquid medium heated by the liquid cooling component 130 can re-enter the liquid cooling component 130 through the third pipeline 500 for heat exchange and re-enter the first heating part 310 after passing through the first heating part 310, so that the first heating part 310 can heat the liquid medium multiple times to improve efficiency; at the same time, the setting of the circulation pipeline reduces the amount of liquid medium required for the liquid cooling component 130, improves the utilization rate of the liquid medium, and avoids waste.

[0117] The circulation component may be a one-way valve 610 , a pump 620 for guiding the flow of water, or a combination of the two, so that the water flows from the first heating part 310 through the third pipeline 500 to the liquid inlet 131 of the liquid cooling component 130 .

[0118] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims.
