[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] Combination Figure 1 and Figure 2 According to an embodiment of the present invention, a refrigeration device 100 for a drinking water device 1000 comprises: a housing 20, a heat exchanger 30 and a water guide 10, wherein the housing 20 is provided with a water storage chamber 201; the heat exchanger 30 is provided in the water storage chamber 201 and is configured to refrigerate the medium in the water storage chamber 201; the water guide 10 has a flow channel for liquid circulation, and the water guide 10 is provided in the water storage chamber 201 and exchanges heat with the medium in the water storage chamber 201. Specifically, the heat exchanger 30 and the water guide 10 are both provided in the water storage chamber 201, and the water storage chamber 201 can store a refrigeration medium, or water for heat exchange with the heat exchanger 30 and the water guide 10. In this way, the heat exchanger 30 can exchange heat with the medium in the water storage chamber 201, and the medium in the water storage chamber 201 can then exchange heat with the water in the water guide 10, so that the heat exchanger 30 can cool or cool the liquid in the water guide 10, so that the water guide 10 can export cold water or cold water of a predetermined temperature. In addition, the water guide 10 and the heat exchanger 30 are arranged at intervals, so that there is a refrigerant medium between the water guide 10 and the heat exchanger 30, and the refrigerant medium can be used for heat exchange, thereby improving the controllability and stability of the refrigeration, and avoiding the heat exchanger 30 and the water guide 10 being too close to each other, resulting in the temperature of the heat exchanger 30 being too low and causing the liquid in the water guide 10 to freeze.

[0037] According to the refrigeration device 100 of the embodiment of the present invention, by arranging the heat exchanger 30 in the water storage chamber 201, the heat exchange efficiency of the heat exchanger 30 can be improved, and the refrigeration effect can be improved. However, the heat exchanger 30 directly exchanges heat with the outlet water in the water storage chamber 201, and ice may occur, thereby affecting the outlet water. Therefore, in order to prevent the outlet water from freezing, a water guide 10 can be arranged in the water storage chamber 201, and the water to be refrigerated flows in the water guide 10. When cooling the water, the water in the water guide 10 can be indirectly cooled by the medium in the water storage chamber 201, thereby improving the stability of the refrigeration and avoiding the problem of outlet water freezing.

[0038] Furthermore, the refrigeration device 100 further includes a temperature measuring element 41, which detects the temperature of the medium in the water storage chamber 201. The operation of the heat exchanger 30 can be controlled by the temperature measuring element 41, which can ensure the refrigeration effect and prevent the refrigeration temperature from being too low to cause ice. Specifically, the temperature measuring element 41 detects the temperature of the medium in the water storage chamber 201, and can transmit the temperature signal to the control element. The control element can compare the test value of the temperature measuring element 41 with a preset value to determine the refrigeration effect of the heat exchanger 30 on the medium in the water storage chamber 201, control the operation of the heat exchanger 30, and improve the refrigeration effect. During the refrigeration process, in order to prevent ice or ice blockage in the water guide 10, it can also be determined whether the medium temperature is lower than a preset value. If it is lower, it means that the medium temperature is too low and may freeze or cause the liquid in the water guide 10 to freeze, so that the signal can be transmitted to the control element, and the control element heat exchanger 30 or the refrigeration device 100 stops working, and the residual temperature of the medium in the water storage chamber 201 can continue to exchange heat with the liquid in the water guide 10.

[0039] According to the refrigeration device 100 for drinking water equipment 1000 of the embodiment of the present invention, by arranging the heat exchanger 30 and the water guide member 10 distributed at intervals in the water storage chamber 201, the heat exchanger 30 can cool the medium in the water storage chamber 201, and the water guide member 10 can exchange heat with the medium in the water storage chamber 201, thereby improving the refrigeration efficiency and refrigeration effect. In addition, the refrigeration device 100 also includes a temperature measuring element 41 for detecting the temperature of the medium in the water storage chamber 201, which can prevent ice blockage in the water guide member due to too low a medium temperature, improve the cold water outlet effect, and effectively control the outlet water temperature.

[0040] Furthermore, in some embodiments of the present invention, the temperature sensing probe 411 of the temperature measuring element 41 is disposed between the heat exchanger 30 and the water guide 10. In combination with the above, during the refrigeration process, the heat exchanger 30 exchanges heat with the medium in the water storage chamber 201, and the medium then exchanges heat with the liquid in the water guide 10. Therefore, the temperature measuring element 41 is disposed between the heat exchanger 30 and the water guide 10, where the medium is close to both the heat exchanger 30 and the water guide 10, which can improve the accuracy of the temperature detection of the refrigeration medium, so that the measured temperature can reflect the refrigeration effect of the heat exchanger 30 on the medium and the heat exchange effect of the medium on the water guide 10, which is conducive to improving the refrigeration effect of the refrigeration device 100.

[0041] Combination Figure 2 and Figure 3 In some embodiments of the present invention, the heat exchanger 30 is arranged around the water guide 10, which can increase the area of ​​the heat exchanger 30 and the water guide 10, which is conducive to improving the refrigeration efficiency and refrigeration effect. In the top-down projection, the temperature sensing probe 411 of the temperature measuring element 41 is arranged between the heat exchanger 30 and the water guide 10, which can improve the accuracy of the temperature detection of the refrigerant medium between the heat exchanger 30 and the water guide 10. In addition, when the detected temperature is too low and the refrigeration device 100 or the refrigeration system is controlled to stop working, the medium between the heat exchanger 30 and the water guide 10 can have a certain amount of ice storage. In this way, after the shutdown, the refrigerant medium can continue to exchange heat with the liquid in the water guide 10, thereby increasing the cold water output of the water guide 10 and improving the refrigeration effect of the refrigeration system. That is to say, by reasonably setting the position of the temperature measuring element 41, it can not only be close to the heat exchanger 30 to improve the accuracy of detecting the refrigeration effect of the heat exchanger 30, but also the medium between the heat exchanger 30 and the water guide member 10 can generate a certain amount of ice storage when the refrigeration device 100 is shut down, thereby increasing the cold water output.

[0042] Combination Figure 2 In some embodiments of the present invention, the temperature sensing probe 411 of the temperature measuring element 41 is not higher than the upper edge of the heat exchanger 30, so that the temperature sensing probe of the temperature measuring element 41 can detect the temperature of the medium around the heat exchanger 30, which is conducive to more accurately reflecting the cooling effect of the heat exchanger 30 on the medium, thereby facilitating the judgment of the cooling effect on the liquid in the water guide 10.

[0043] In some embodiments of the present invention, the temperature sensing probe 411 of the temperature measuring element 41 is not higher than the upper edge of the water guiding member 10. The temperature sensing probe of the temperature measuring element 41 can detect the temperature of the medium surrounding the water guiding member 10, which is conducive to more accurately reflecting the cooling effect of the medium on the liquid in the water guiding member 10.

[0044] In some embodiments of the present invention, the temperature sensing probe 411 of the temperature measuring element 41 is not higher than the highest liquid level in the water storage chamber 201, so that the temperature sensing probe of the temperature measuring element 41 can extend into the medium in the water storage chamber 201, thereby improving the accuracy of medium temperature detection.

[0045] In some embodiments of the present invention, the temperature measuring element 41 is separated from the heat exchanger 30 by a predetermined distance, which can improve the accuracy of medium temperature detection. Since the temperature of the medium close to the heat exchanger 30 is lower than the temperature of the medium in other areas, the temperature measuring element 41 is separated from the heat exchanger 30 by a predetermined distance, so that the detected medium temperature is closer to the temperature of the medium exchanging heat with the water guide 10, thereby improving the judgment of the heat exchange effect of the water guide 10, thereby preventing the water in the water guide 10 from ice blockage.

[0046] Combination Figure 2 In some embodiments of the present invention, the temperature sensing probe 411 of the temperature measuring element 41 and the heat exchanger 30 both extend in the up-down direction, and the lower end of the temperature sensing probe 411 of the temperature measuring element 41 is not lower than 1 / 2 to 2 / 3 of the up-down direction of the heat exchanger 30, which can improve the coordination effect between the temperature sensing probe of the temperature measuring element 41 and the heat exchanger 30, so that the temperature sensing probe can measure the temperature of the medium in a certain area around the heat exchanger 30, rather than just the temperature of a point, which is conducive to improving the accuracy of temperature detection.

[0047] More specifically, the temperature sensing probe of the temperature measuring element 41 extends between the heat exchanger 30 and the water guide 10 and extends downward for a certain distance to improve the accuracy of temperature detection. For example, the heat exchanger 30 and the water guide 10 extend in the up-down direction. At a position far from the heat exchanger 30, the temperature of the medium will be slightly higher than the temperature of the medium at a position close to the heat exchanger 30. If the temperature sensing probe is arranged at the upper end or the lower end of the heat exchanger 30 or the water guide 10, the detection value will be affected by the medium far from the heat exchanger 30, which may result in a higher measured temperature.

[0048] Furthermore, the temperature sensing probe of the temperature measuring element 41 may include multiple sections connected in the up-down direction, wherein each section can detect the temperature separately. Figure 2 The temperature sensing probe includes a first section and a second section, the outer diameter of the first section is larger than the outer diameter of the second section, the first end 31 is located at the upper part of the heat exchanger 30 or the water guide 10, and the second section is located at the middle or lower part of the heat exchanger 30 or the water guide 10. Therefore, the multi-section temperature sensing probe can detect the temperature of the medium in different areas of the heat exchanger 30 and the water guide 10, which is conducive to more accurately reflecting the temperature of the medium in the water storage chamber 201, so that the operation of the refrigeration device 100 or the refrigeration system can be reasonably controlled according to multiple temperature values.

[0049] It should be noted that the up and down direction may be the height direction of the refrigeration device 100, see Figure 1BB direction in.

[0050] Combination Figure 3 and Figure 4 In some embodiments of the present invention, the water guide 10 includes an inlet pipe 11, an outlet pipe 12 and a heat exchange structure 13, one end of the inlet pipe 11 is connected to the upper end of the heat exchange structure 13 and the other end is connected to the upper end of the box 20; one end of the outlet pipe 12 is connected to the lower end of the heat exchange structure 13 and extends upward to the upper end of the box 20. Thus, water that needs to be refrigerated can enter the water guide 10 from the inlet pipe 11 and flow through the flow channel of the heat exchange structure 13 before being discharged from the outlet pipe 12, wherein the inlet pipe 11 is located at the upper end of the heat exchange structure 13, and the water can naturally flow to the heat exchange structure 13 after entering, and the outlet pipe 12 at the lower end of the heat exchange structure 13 allows the water to fully exchange heat in the heat exchange structure 13, which is beneficial to increase the heat exchange area and improve the heat exchange efficiency. The outlet pipe 12 extends upward from the lower end of the heat exchange structure 13, which can facilitate the arrangement of the water outlet and extend the distance of the liquid flow channel, thereby improving the stability of the outlet water and the stability of the outlet water temperature.

[0051] Exemplarily, the medium can be water, and the water guide 10 can be used to transport water, that is, the medium in the water storage chamber 201 and the liquid transported in the water guide 10 can be the same fluid, and the drinking water equipment 1000 may include a water inlet component, through which the medium can be introduced into the water storage chamber 201 and the fluid can be supplied to the water guide 10, which is conducive to simplifying the pipeline and structure of the drinking water equipment 1000.

[0052] Combination Figure 3 In some embodiments of the present invention, the heat exchanger 30 surrounds the heat exchange structure 13, and the temperature sensing probe of the temperature measuring element 41 is arranged between the heat exchange structure 13 and the heat exchanger 30. Since the heat exchange structure 13 is the main part of the water guide 10 for heat exchange, the temperature sensing probe of the temperature measuring element 41 detects the temperature of the medium between the heat exchanger 30 and the heat exchange structure 13, which is conducive to judging the refrigeration state of the liquid in the heat exchange structure 13. In addition, when the detected temperature reaches the preset temperature value, the refrigeration system is controlled to stop working. The preset temperature value can be set to make the medium between the heat exchanger 30 and the heat exchange structure 13 or the water guide 10 in an ice storage state, thereby avoiding ice blockage of the liquid in the heat exchange structure 13 or the water guide 10, and the ice storage amount of the medium between the heat exchanger 30 and the heat exchange structure 13 or the water guide 10 can continue to exchange heat with the liquid in the heat exchange structure 13 or the water guide 10, thereby increasing the water output and improving the refrigeration effect of the refrigeration device 100.

[0053] In some embodiments of the present invention, the heat exchange structure 13 extends in a spiral from top to bottom, which can effectively utilize the vertical space in the water storage chamber 201, and can also increase the heat exchange area of ​​the heat exchange structure 13, thereby improving the heat exchange capacity and heat exchange efficiency. Specifically, the heat exchange structure 13 is configured as a heat exchange tube extending in a spiral from top to bottom, and the liquid flows in the heat exchange tube. Alternatively, the heat exchange structure 13 is in the form of a sheet or plate, and is filled with liquid. The liquid flows from the water inlet pipe 11 through the heat exchange structure 13 for heat exchange and flows out from the water outlet pipe 12.

[0054] Combination Figure 3 and Figure 4 In some embodiments of the present invention, the heat exchanger 30 includes a first end 31, a second end 32, and a plurality of heat exchange sections 33 distributed in the up-down direction. The plurality of heat exchange sections 33 surround the outer side of the water guide 10 in the up-down direction, which is conducive to increasing the matching area of ​​the heat exchanger 30 with the water guide 10 and improving the refrigeration effect. Specifically, the plurality of heat exchange sections 33 can refrigerate the surrounding medium. Since the plurality of heat exchange sections 33 are arranged around the outer side of the water guide 10, the medium exchanging heat with the plurality of heat exchange sections 33 can surround the water guide 10 and exchange heat with the liquid in the water guide 10, thereby reducing the loss of cold and improving the refrigeration efficiency. Furthermore, the first end 31 and the second end 32 are respectively arranged at the opposite ends of the plurality of heat exchange sections 33 and are located above the plurality of heat exchange sections 33, which can prevent the medium from being retained on the end surfaces on both sides of the heat exchanger 30, play the effect of protecting the inlet and outlet of the heat exchanger 30, and facilitate spatial arrangement. Specifically, the heat exchanger 30 can be an evaporator, the first end 31 can be an evaporation end, and the second end 32 can be an outlet end. The evaporation end and the outlet end are located at the upper part, which can prevent the medium from being retained on the surface of the evaporator. The outlet end is located at the upper part to facilitate the discharge of bubbles, avoid the impact of bubble burst on the inner wall of the evaporator, and reduce mechanical damage.

[0055] Combination Figure 2 In some embodiments of the present invention, the refrigeration device 100 further includes a water level detection member 42, which is used to detect the water level in the water storage chamber 201 to ensure that there is an appropriate amount of medium in the water storage chamber 201, and to achieve the heat exchange effect of the medium between the heat exchanger 30 and the water guide member 10, thereby ensuring the refrigeration effect and improving the refrigeration efficiency. Specifically, the water level detection member 42 can transmit signals with the control element, so that after the water level detection member 42 detects the water level in the water storage chamber 201, it can determine whether water needs to be added to the water storage chamber 201, and realize automatic water addition. It can also detect the position of the water level rise during the water addition process, control the amount of water added, and prevent overflow.

[0056] In some embodiments of the present invention, the detection position of the water level detection member 42 is not lower than the upper edge of the heat exchanger 30, which can ensure that the heat exchanger 30 can fully contact the medium in the water storage chamber 201 to achieve a cooling effect on the medium.

[0057] In some embodiments of the present invention, the detection position of the water level detection member 42 is not lower than the upper edge of the water guide member 10, which can ensure that the water guide member 10 can fully contact the refrigerant medium in the water storage chamber 201 to achieve the cooling effect of the refrigerant medium on the water guide member 10.

[0058] In some embodiments of the present invention, the water level detection member 42 is disposed inside the heat exchanger 30 or the water guide 10, so as to facilitate the measurement of the medium water level in the water storage chamber 201, and the relative relationship between the medium water level and the heat exchanger 30 or the water guide 10. Specifically, the water level detection member 42 can be disposed inside the water guide 10, the water guide 10 extends spirally in the up-down direction, and the inside of the water guide 10 has a space suitable for arranging the water level detection member 42. Of course, when the interval between the water guide 10 and the heat exchanger 30 is large, the water level detection member 42 can also be disposed inside the heat exchanger 30, or between the water guide 10 and the heat exchanger 30.

[0059] In some embodiments of the present invention, the water level detection member 42 is a float structure, which can move synchronously with the medium water level, thereby improving the detection accuracy and reliability, and has a simple structure and is easy to construct.

[0060] Exemplarily, the water level detection member 42 may be a float, an ultrasonic level meter, or the like.

[0061] Optionally, the water level detection member 42 includes a float, which is disposed in the water storage chamber 201 and is used to detect or monitor the water level of the water storage chamber 201. The float can float up and down as the water level in the water storage chamber 201 rises and falls. For example, the position of the float can trigger a valve to open and close the liquid inlet 210. The float can accurately track the change of the water level in the water storage chamber 201, and can avoid affecting the performance of the float when the temperature in the water storage chamber 201 decreases, so that the float can stably detect the liquid level in the water storage chamber 201.

[0062] In some embodiments of the present invention, the refrigeration device 100 further includes an agitator, which is configured to move the medium in the water storage chamber 201. The agitator is arranged in the up and down directions to increase the stirring range.

[0063] Combination Figure 4 In some embodiments of the present invention, the heat exchanger 30 includes a plurality of heat exchange sections 33 distributed in the up-down direction, the heat exchange sections 33 extend in the direction surrounding the agitator, and the plurality of heat exchange sections 33 are connected, so as to increase the contact area between the heat exchanger 30 and the medium, and improve the cooling efficiency and uniformity of the heat exchanger 30 for the medium, and the heat exchange sections 33 extend in the direction surrounding the agitator, and the heat exchanger 30 cooperates with the agitator to further improve the temperature uniformity of the medium in the water storage chamber 201.

[0064] In some embodiments of the present invention, Figure 1 and Figure 2 The box body 20 includes a barrel body 22 and a cover body 21. The cover body 21 is covered on the upper end of the barrel body 22. The cover body 21 is covered on the barrel body 22. The cover body 21 is provided with a liquid inlet 210 for injecting a medium into the water storage chamber 201, and the barrel body 22 is provided with a liquid outlet 220 for discharging the medium. The liquid inlet 210 is provided at the upper end of the box body 20, and the liquid outlet 220 is provided at the lower end of the box body 20, so as to facilitate the introduction of the medium into the water storage chamber 201 through the liquid inlet 210 and the discharge of the medium in the water storage chamber 201 through the liquid outlet 220.

[0065] Specifically, the water inlet pipe 11 of the water guide member 10 is connected to the water inlet joint 110, and the water outlet pipe 12 is connected to the water outlet joint 120. The water inlet joint 110 extends out of the cover body 21 to facilitate connection with the water inlet assembly, and the water outlet joint 120 extends out of the cover body 21 to facilitate connection with the water outlet structure.

[0066] The upper end of the water level detection member 42 is provided with a connection terminal, which extends out of the cover body 21.
