[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] Combination Figure 1 and Figure 2According to an embodiment of the present invention, a refrigeration device 100 for a drinking water equipment 1000 includes: a housing 20, a heat exchanger 30, and a water guide 10. The housing 20 is provided with a water storage chamber 201; the heat exchanger 30 is disposed in the water storage chamber 201 and configured to refrigerate the medium in the water storage chamber 201; the water guide 10 has a flow channel for liquid flow and is disposed in the water storage chamber 201 to exchange heat with the medium in the water storage chamber 201. Specifically, both the heat exchanger 30 and the water guide 10 are disposed in the water storage chamber 201, which can store the 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. This achieves the effect of cooling or lowering the liquid in the water guide 10 by the heat exchanger 30, allowing the water guide 10 to discharge cold water or cold water at a predetermined temperature. Furthermore, the water guide 10 and the heat exchanger 30 are spaced apart, allowing a cooling medium between them. This enables heat exchange using the cooling medium, improving the controllability and stability of cooling. It also prevents the heat exchanger 30 from being too close to the water guide 10, which could cause the temperature of the heat exchanger 30 to drop too low and the liquid in the water guide 10 to freeze.

[0038] According to the refrigeration device 100 of this utility model embodiment, by placing the heat exchanger 30 inside the water storage chamber 201, the heat exchange efficiency of the heat exchanger 30 can be improved, thus enhancing the cooling effect. However, since the heat exchanger 30 directly exchanges heat with the outlet water inside the water storage chamber 201, icing may occur, affecting the outlet water. Therefore, to prevent the outlet water from freezing, a water guide 10 can be installed inside the water storage chamber 201, through which the water requiring cooling flows. When cooling the water, the medium inside the water storage chamber 201 can indirectly cool the water inside the water guide 10, thereby improving the stability of the cooling process and preventing the outlet water from freezing.

[0039] Furthermore, the refrigeration device 100 also includes a temperature sensing 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 via the temperature sensing element 41, ensuring both cooling effect and preventing freezing due to excessively low cooling temperatures. Specifically, the temperature sensing element 41 detects the temperature of the medium in the water storage chamber 201 and transmits the temperature signal to a control element. The control element can compare the measured value from the temperature sensing element 41 with a preset value to determine the cooling effect of the heat exchanger 30 on the medium in the water storage chamber 201, and control the operation of the heat exchanger 30 to improve the cooling effect. During the cooling process, to prevent freezing 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 indicates that the medium temperature is too low and may freeze or cause the liquid in the water guide 10 to freeze. The signal can then be transmitted to the control element, which will stop the operation of the heat exchanger 30 or the refrigeration device 100. 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.

[0040] According to the present invention, the refrigeration device 100 for a drinking water device 1000 is provided with heat exchangers 30 and water guides 10 spaced apart in the water storage chamber 201. The heat exchangers 30 can cool the medium in the water storage chamber 201, and the water guides 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 guides due to the low temperature of the medium, improve the cold water output effect, and effectively control the output water temperature.

[0041] Combination Figure 2 In some embodiments of this utility model, the refrigeration device 100 also includes a water level detection element 42. The water level detection element 42 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, so as to achieve the heat exchange effect between the heat exchanger 30 and the water guide 10, thereby ensuring the refrigeration effect and improving the refrigeration efficiency. Specifically, the water level detection element 42 can transmit signals with the control element. In this way, after detecting the water level in the water storage chamber 201, the water level detection element 42 can determine whether water needs to be added to the water storage chamber 201, realize automatic water addition, and can also detect the position of the water level rise during the water addition process to control the amount of water added and prevent overflow.

[0042] In some embodiments of this utility model, the detection position of the water level detection element 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 cavity 201 to achieve the cooling effect on the medium.

[0043] In some embodiments of this utility model, the detection position of the water level detection element 42 is not lower than the upper edge of the water guide element 10, which can ensure that the water guide element 10 can fully contact the cooling medium in the water storage cavity 201 and realize the cooling effect of the cooling medium on the water guide element 10.

[0044] In some embodiments of this utility model, the water level detection element 42 is disposed inside the heat exchanger 30 or the water guide 10, facilitating 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 element 42 can be disposed inside the water guide 10, which extends spirally in the vertical direction, and the inner side of the water guide 10 has a space suitable for arranging the water level detection element 42. Of course, when the distance between the water guide 10 and the heat exchanger 30 is large, the water level detection element 42 can also be disposed inside the heat exchanger 30, or between the water guide 10 and the heat exchanger 30.

[0045] In some embodiments of this utility model, the water level detection element 42 is a float-type structure. The float structure can move synchronously with the water level of the medium, which helps to improve the detection accuracy and reliability, and the structure is simple and easy to construct.

[0046] For example, the water level detection element 42 can be a float, an ultrasonic level gauge, etc.

[0047] Optionally, the water level detection element 42 includes a float ball disposed in the water storage chamber 201 and used to detect or monitor the water level in the water storage chamber 201. The float ball 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 ball can trigger a valve to open and close the liquid inlet 210. The float ball can accurately track changes in the water level in the water storage chamber 201 and can avoid affecting the performance of the float ball when the temperature in the water storage chamber 201 decreases, making it easy for the float ball to stably detect the liquid level in the water storage chamber 201.

[0048] Furthermore, in some embodiments of this utility model, the temperature sensing probe 411 of the temperature sensing element 41 is disposed between the heat exchanger 30 and the water guide 10. In conjunction with the foregoing, 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, by disposing the temperature sensing element 41 between the heat exchanger 30 and the water guide 10, where the medium is simultaneously close to both the heat exchanger 30 and the water guide 10, the accuracy of temperature detection of the refrigeration medium can be improved. This allows the measured temperature to 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, thereby improving the refrigeration effect of the refrigeration device 100.

[0049] Combination Figure 2 and Figure 3In some embodiments of this utility model, the heat exchanger 30 is arranged around the water guide 10, which increases the contact area between the heat exchanger 30 and the water guide 10, thus improving refrigeration efficiency and effect. In the top-down projection, the temperature sensing probe 411 of the temperature sensing element 41 is located between the heat exchanger 30 and the water guide 10, which improves the accuracy of temperature detection of the refrigerant medium between the heat exchanger 30 and the water guide 10. Furthermore, when the detected temperature is too low, and the refrigeration device 100 or the refrigeration system stops working, the medium between the heat exchanger 30 and the water guide 10 can have a certain ice storage capacity. Thus, after 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. In other words, by reasonably setting the position of the temperature sensing element 41, it can not only be close to the heat exchanger 30 to improve the accuracy of detecting the cooling effect of the heat exchanger 30, but also allow the medium between the heat exchanger 30 and the water guide 10 to generate a certain amount of ice storage when the refrigeration device 100 is stopped, thereby increasing the cold water output.

[0050] Combination Figure 2 In some embodiments of this utility model, the temperature sensing probe 411 of the temperature sensing element 41 is not higher than the upper edge of the heat exchanger 30, so that the temperature sensing probe of the temperature sensing 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 making it easier to judge the cooling effect on the liquid in the water guide 10.

[0051] In some embodiments of this utility model, the temperature sensing probe 411 of the temperature sensing element 41 is not higher than the upper edge of the water guide 10. The temperature sensing probe of the temperature sensing element 41 can detect the temperature of the medium around the water guide 10, which is conducive to more accurately reflecting the cooling effect of the medium on the liquid inside the water guide 10.

[0052] In some embodiments of this utility model, the temperature sensing probe 411 of the temperature sensing element 41 is not higher than the highest liquid level in the water storage cavity 201, so that the temperature sensing probe of the temperature sensing element 41 can be inserted into the medium in the water storage cavity 201, thereby improving the accuracy of medium temperature detection.

[0053] In some embodiments of this invention, the temperature sensing element 41 is spaced a predetermined distance from the heat exchanger 30, which improves the accuracy of medium temperature detection. Since the temperature of the medium near the heat exchanger 30 is lower than the temperature of the medium in other areas, the predetermined distance between the temperature sensing element 41 and the heat exchanger 30 ensures that the detected medium temperature is closer to the temperature of the medium exchanging heat with the water guide 10. This improves the assessment of the heat exchange effect of the water guide 10 and prevents ice blockage in the water guide 10.

[0054] Combination Figure 2In some embodiments of this utility model, the temperature sensing probe 411 of the temperature sensing element 41 and the heat exchanger 30 both extend in the vertical direction. The lower end of the temperature sensing probe 411 of the temperature sensing element 41 is not lower than 1 / 2 to 2 / 3 of the vertical direction of the heat exchanger 30. This can improve the cooperation effect between the temperature sensing probe of the temperature sensing 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 single point, which is beneficial to improving the accuracy of temperature detection.

[0055] More specifically, the temperature sensing probe of the temperature sensing element 41 extends between the heat exchanger 30 and the water guide 10, and extends downwards a certain distance to improve the accuracy of temperature detection. For example, the heat exchanger 30 and the water guide 10 extend vertically. At positions away from the heat exchanger 30, the temperature of the medium will be slightly higher than the temperature of the medium closer to the heat exchanger 30. If the temperature sensing probe is located at the upper or lower end of the heat exchanger 30 or the water guide 10, the detected value will be affected by the medium away from the heat exchanger 30, which may result in a higher measured temperature.

[0056] Furthermore, the temperature sensing probe of the temperature sensing element 41 may include multiple segments connected in the vertical direction, each of which can detect temperature independently. Combined with... Figure 2 The temperature sensing probe includes a first segment and a second segment. The outer diameter of the first segment is larger than that of the second segment. The first end 31 is located at the upper part of the heat exchanger 30 or the water guide 10, and the second segment is located at the middle or lower part of the heat exchanger 30 or the water guide 10. Therefore, the multi-segment temperature sensing probe can detect the temperature of the medium in different areas of the heat exchanger 30 and the water guide 10, which facilitates a more accurate response to the temperature of the medium in the water storage chamber 201. This allows for reasonable control of the operation of the refrigeration device 100 or the refrigeration system based on multiple temperature values.

[0057] It should be noted that the up and down direction can be the height direction of the refrigeration unit 100, see [reference]. Figure 1 The BB direction in the middle.

[0058] Combination Figure 3 and Figure 4In some embodiments of this utility model, 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 housing 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 housing 20. Thus, water requiring cooling can enter the water guide 10 through the inlet pipe 11, flow through the flow channel of the heat exchange structure 13, and then exit through the outlet pipe 12. The inlet pipe 11 is located at the upper end of the heat exchange structure 13, allowing water to flow naturally into the structure and then through the outlet pipe 12 at the lower end of the structure, ensuring sufficient heat exchange within the structure and facilitating increased heat exchange area and efficiency. The outlet pipe 12 extends upward from the lower end of the heat exchange structure 13, facilitating the arrangement of the outlet and extending the liquid flow channel distance, thus improving the stability of the water output and the temperature.

[0059] For example, 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. The drinking water device 1000 may include a water inlet assembly, 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 helps to simplify the piping and structure of the drinking water device 1000.

[0060] Combination Figure 3 In some embodiments of this utility model, the heat exchanger 30 surrounds the heat exchange structure 13, and the temperature sensing probe of the temperature sensing element 41 is located 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 sensing element 41 detects the temperature of the medium between the heat exchanger 30 and the heat exchange structure 13, which is beneficial for judging the cooling 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. This can prevent the liquid in the heat exchange structure 13 or the water guide 10 from freezing, and the ice-storage 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 cooling effect of the refrigeration device 100.

[0061] In some embodiments of this invention, the heat exchange structure 13 extends spirally from top to bottom, which can effectively utilize the vertical space within the water storage cavity 201, increase the heat exchange area of ​​the heat exchange structure 13, and improve the heat exchange capacity and efficiency. Specifically, the heat exchange structure 13 is constructed as a heat exchange tube extending spirally from top to bottom, with liquid flowing inside the heat exchange tube. Alternatively, the heat exchange structure 13 can be sheet-like or plate-like, filled with liquid, with the liquid flowing out from the outlet pipe 12 after heat exchange through the heat exchange structure 13 from the inlet pipe 11.

[0062] Combination Figure 3 and Figure 4 In some embodiments of this utility model, the heat exchanger 30 includes a first end 31, a second end 32, and a plurality of heat exchange sections 33 distributed in a vertical direction. The plurality of heat exchange sections 33 surround the outside of the water guide 10 in a vertical direction, which helps to increase the contact area between the heat exchanger 30 and the water guide 10 and improve the cooling effect. Specifically, the plurality of heat exchange sections 33 can cool the surrounding medium. Since the plurality of heat exchange sections 33 are arranged around the outside 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 energy and improving the cooling efficiency. Further, the first end 31 and the second end 32 are respectively located at opposite ends of the plurality of heat exchange sections 33 and above the plurality of heat exchange sections 33, which can prevent the medium from accumulating on the end surfaces on both sides of the heat exchanger 30, thereby protecting the inlet and outlet of the heat exchanger 30 and facilitating spatial arrangement. Specifically, the heat exchanger 30 can be an evaporator, the first end 31 can be the evaporation end, and the second end 32 can be the outlet end. The evaporation end and the outlet end are located at the top, which can prevent the medium from stagnating on the surface of the evaporator. The outlet end is located at the top, which facilitates the discharge of air bubbles and avoids the impact of air bubble rupture on the inner wall of the evaporator, thus reducing mechanical damage.

[0063] In some embodiments of this utility model, the refrigeration device 100 further includes a stirrer, which is configured to move the medium in the water storage chamber 201. The stirrer is arranged in the vertical direction to increase the stirring range.

[0064] Combination Figure 4 In some embodiments of this utility model, the heat exchanger 30 includes a plurality of heat exchange sections 33 distributed in the vertical direction. The heat exchange sections 33 extend in the direction surrounding the stirrer, and the plurality of heat exchange sections 33 are connected to each other, which facilitates increasing the contact area between the heat exchanger 30 and the medium, improving the cooling efficiency and uniformity of the medium by the heat exchanger 30. In addition, the heat exchange sections 33 extend in the direction surrounding the stirrer, and the heat exchanger 30 and the stirrer cooperate to further improve the temperature uniformity of the medium in the water storage chamber 201.

[0065] In some embodiments of this utility model, combined with Figure 1 and Figure 2The housing 20 includes a barrel 22 and a cover 21. The cover 21 covers the upper end of the barrel 22 and has an inlet 210 for injecting a medium into the water storage chamber 201. The barrel 22 has an outlet 220 for discharging the medium. The inlet 210 is located at the upper end of the housing 20, and the outlet 220 is located at the lower end of the housing 20, facilitating the introduction of a medium into the water storage chamber 201 through the inlet 210 and the discharge of a medium from the water storage chamber 201 through the outlet 220.

[0066] Specifically, the inlet pipe 11 of the water guide 10 is connected to the inlet connector 110, and the outlet pipe 12 is connected to the outlet connector 120. The inlet connector 110 extends out of the cover 21 to be connected to the inlet assembly, and the outlet connector 120 extends out of the cover 21 to be connected to the outlet structure.

[0067] The upper end of the water level detection element 42 is provided with a wiring terminal, which extends out of the cover 21. The wiring terminal of the temperature measuring element 41 also extends out of the cover 21. This facilitates electrical connection or signal transmission between the water level detection element 42 and the temperature measuring element 41.

[0068] More specifically, the tank 22 includes an inner tank 221 and an outer tank 222. The inner tank 221 is located inside the outer tank 222. A first insulation layer 23 is provided between the inner tank 221 and the outer tank 222. The first insulation layer 23 can prevent the loss of cold air in the box 20 and prevent external heat from entering the box 20, so as to maintain a low temperature environment in the water storage chamber 201 and improve the cooling efficiency.

[0069] In addition, the cover 21 includes an inner cover 211 and an outer cover 212, which are stacked together. The inner cover 211 covers the barrel 22, and a second insulation layer 24 is provided between the inner cover 211 and the outer cover 212.

[0070] In some embodiments of this utility model, the heat exchanger 30 is disposed in the water storage cavity 201 and spaced apart from the inner surface of the water storage cavity 201. The medium can flow in the gap between the heat exchanger 30 and the water storage cavity 201, which can improve the cooling efficiency of the heat exchanger 30 on the medium and avoid the loss of cooling capacity due to direct contact between the heat exchanger 30 and the inner surface of the water storage cavity 201.

[0071] Furthermore, combined Figure 2The inner circumferential surface of the water storage cavity 201 is provided with multiple ribs 25, which are distributed along the circumference of the water storage cavity 201. The ribs 25 separate the heat exchanger 30 from the inner surface of the water storage cavity 201. The multiple ribs 25 on the inner circumferential surface of the water storage cavity 201 can improve the structural strength of the water storage cavity 201, enabling it to adapt to temperature changes. On the other hand, it facilitates the separation of the heat exchanger 30 from the inner surface of the water storage cavity 201, allowing the medium to flow between the inner surface of the water storage cavity 201 and the heat exchanger 30, thereby improving the cooling efficiency of the heat exchanger 30 for the medium.
