Detailed Implementation

[0026] 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.

[0027] The following description, with reference to the accompanying drawings, describes the cooling water circuit system and the drinking water equipment of this utility model embodiment.

[0028] Figure 1 This is a block diagram of the cooling water circuit system of the drinking water equipment according to the example of this utility model.

[0029] Specifically, in some examples of this utility model, such as Figure 1 As shown, the cooling water system 1000 includes: a cold water storage tank 10, an outlet water pipe 20, a cooling component 30, a stirring component 40, a temperature detection component 50, an outlet water detection component 60, and a control component 70.

[0030] The water outlet pipe 20 is installed inside the cold water storage tank 10; the refrigeration component 30 is connected to the cold water storage tank 10; the stirring component 40 is connected to the cold water storage tank 10; the temperature detection element 50 is configured to detect the water storage temperature of the cold water storage tank 10; the water outlet detection element 60 is configured to detect the water outlet flow rate of the water outlet pipe 20; the control component 70 is connected to the temperature detection element 50, the water outlet detection element 60, the refrigeration component 30 and the stirring component 40 respectively, and the control component 70 is configured to adjust the working state of the refrigeration component 30 and the stirring component 40 according to the temperature detected by the temperature detection element 50 and the flow rate detected by the water outlet detection element 60 respectively.

[0031] It is understood that in this example of the present invention, the control component 70 can dynamically adjust the working state of the cooling component 30 and the stirring component 40 according to the water storage temperature detected by the temperature detection component 50 and the water flow rate detected by the water outlet detection component 60, so that the working state of the cooling component 30 and the stirring component 40 is adapted to the current water flow rate and the current water storage temperature. Thus, the cooling component 30 cools the water stored in the cold water storage tank 10, so that the stored water can exchange heat with the water outlet in the water outlet pipe 20 in real time. And the stirring component 40 stirs the water stored in the cold water storage tank 10, so that the stored water can be uniformly cooled. In this way, while preventing freezing during the cooling process, the energy consumption of the drinking water equipment is reduced.

[0032] Optionally, in the above examples of this utility model, the cold water tank 10 can be other forms of cold storage tank, and the stored water can be other forms of cold storage liquid, such as brine solution or eutectic salt solution. In addition, this utility model does not specifically limit the selection of cold storage tank and cold storage liquid.

[0033] Specifically, in some examples of this utility model, the control component 70 transmits signals to the temperature detection element 50, the water outlet detection element 60, the refrigeration component 30, and the stirring component 40. The control component 70 is configured to adjust the operating speed of the refrigeration component 30 and the operating frequency of the stirring component 40 in real time based on the detected temperature of the temperature detection element 50 and the detected flow rate of the water outlet detection element 60. For example, the temperature detection element 50 detects the water temperature in the cold water storage tank 10 in real time, and the water outlet detection element 60 detects the water flow rate of the water outlet pipe 40 in real time. Based on the water temperature and the water flow rate, they generate corresponding electrical signals and transmit them to the control component 70. At this time, the control component 70 controls the operating speed of the refrigeration component 30 and the operating frequency of the stirring component 40 according to the acquired electrical signals, and dynamically adjusts the working state of the refrigeration component 30 and the stirring component 40 so that the working state of the refrigeration component 30 and the stirring component 40 is adapted to the current water flow rate and the current water temperature.

[0034] For example, when the water temperature in the cold water storage tank 10 is greater than the first preset temperature threshold and the water flow rate in the outlet pipe 20 is greater than the preset flow rate threshold, the control component 70 controls the refrigeration component 30 to operate at the first working speed (high frequency), thereby prioritizing the cold water temperature during the water outlet process. The first preset temperature threshold can be set according to the cold storage capacity of the cold water storage tank 10, for example, the first preset temperature threshold can preferably be 10℃. The first working speed can be set according to the refrigeration capacity of the refrigeration component 30, for example, the first working speed can preferably be 4200 rpm. The preset flow rate threshold can be set according to the pipe diameter of the outlet pipe 20.

[0035] When the water temperature in the cold water storage tank 10 is greater than the second preset temperature threshold and less than or equal to the first preset temperature threshold, and the water flow rate in the outlet pipe 20 is greater than the preset flow rate threshold, the control component 70 controls the refrigeration component 30 to operate at the second working speed (medium frequency) and controls the stirring component 40 to operate at the first working frequency, thereby prioritizing the cold water temperature during the water outlet process. The second working speed is less than the first working speed. In addition, the second preset temperature threshold can be set according to the cold storage capacity of the cold water storage tank 10. For example, the second preset temperature threshold can preferably be 5℃. The second working speed can be set according to the cooling capacity of the refrigeration component 30. For example, the second working speed can preferably be 3500 rpm. The first working frequency can be set according to the stirring capacity of the stirring component 40. For example, the first working frequency can preferably be set synchronously with the start and stop of the refrigeration component 30.

[0036] When the water temperature in the cold water storage tank 10 is greater than the third preset temperature threshold and less than or equal to the second preset temperature threshold, and the water flow rate in the outlet pipe 20 is greater than the preset flow rate threshold, the refrigeration component 30 is controlled by the control component 70 to operate at the third operating speed (medium-low frequency), and the stirring component 40 is controlled to operate at the second operating frequency. This prioritizes ensuring the cold water temperature during the water outlet process. The third operating speed is less than the second operating speed, and the second operating frequency is less than the first operating frequency. Furthermore, the third preset temperature threshold can be set according to the cold storage capacity of the cold water storage tank. For example, the third preset temperature threshold can preferably be 1℃. The third operating speed can be set according to the cooling capacity of the refrigeration component 30. For example, the third operating speed can preferably be 2800 rpm. The second operating frequency can be set according to the stirring capacity of the stirring component 40. For example, the second operating frequency can preferably be 4 minutes on and 1 minute off.

[0037] When the water temperature in the cold water storage tank 10 is greater than the fourth preset temperature threshold and less than or equal to the third preset temperature threshold, and the water flow rate in the outlet pipe 20 is greater than the preset flow rate threshold, the control component 70 controls the refrigeration component 30 to operate at the fourth working speed (low frequency) and controls the stirring component 40 to operate at the third working frequency, thereby prioritizing the maintenance of the cold water temperature during the water outlet process. The fourth working speed is less than the third working speed, and the third working frequency is less than the second working frequency. Furthermore, the fourth preset temperature threshold can be set according to the cold storage capacity of the cold water storage tank 10. For example, the fourth preset temperature threshold can preferably be -2.5℃. The fourth working speed can be set according to the cooling capacity of the refrigeration component 30. For example, the fourth working speed can preferably be 2000 rpm. The third working frequency can be set according to the stirring capacity of the stirring component 40. For example, the second working frequency can preferably be 2 minutes on and 1 minute off.

[0038] In addition, when the water flow rate of the outlet pipe 20 is less than the preset flow rate threshold for a continuous period of time, and the water temperature in the cold storage tank 10 is greater than or equal to the upper limit threshold of the energy-saving temperature, the control component 70 controls the refrigeration component 30 to operate at the fifth operating speed (low frequency), thereby prioritizing the reduction of the power consumption of the drinking water equipment. The upper limit threshold of the energy-saving temperature can be set according to the cold storage capacity of the cold storage tank 10. For example, the upper limit threshold of the energy-saving temperature can preferably be 4°C. The fifth operating frequency can be set according to the cooling capacity of the refrigeration component 30. For example, the fifth operating frequency can preferably be 2000 rpm.

[0039] Furthermore, when the water flow rate of the outlet pipe 20 is less than the preset flow rate threshold for a continuous period of time, and the water temperature in the cold storage tank 10 is less than or equal to the lower limit threshold of the energy-saving temperature, the refrigeration component 30 can be controlled to stop working, so that the cold storage tank 10 enters the heat preservation state, thereby prioritizing the reduction of the power consumption of the drinking water equipment. The lower limit threshold of the energy-saving temperature can be set according to the cold storage capacity of the cold storage tank. For example, the lower limit threshold of the energy-saving temperature can preferably be 1℃.

[0040] Furthermore, in some examples of this utility model, such as Figure 2 As shown, the control component 70 includes a motor controller 71 and a signal controller 72. The signal controller 72 is connected to the temperature detection element 50 and the water outlet detection element 60, respectively, and is configured to determine the operating parameters of the refrigeration component 30 and the stirring component 40 based on the detected temperature of the temperature detection element 50 and the detected flow rate of the water outlet detection element 60. The motor controller 71 is connected to the signal controller 72 and is configured to control the refrigeration component 30 based on the operating parameters of the refrigeration component 30 and to control the stirring component 40 based on the operating parameters of the stirring component 40.

[0041] Specifically, in some examples of this utility model, the signal controller 72 can receive electrical signals from the temperature detection element 50 and the water outlet detection element 60. Then, based on the electrical signals fed back by the two, it calculates the required operating speed of the refrigeration component 30 and the required operating frequency of the stirring component 40, and generates corresponding operating parameters to achieve precise motion control. The motor controller 71 can control the movement of the refrigeration component 30 and the stirring component 40 respectively according to the operating parameters, thereby controlling the operating speed of the refrigeration component 30 and the operating frequency of the stirring component 40. Thus, by setting the motor controller 71 and the signal controller 72 to work together, the operating speed of the refrigeration component 30 and the operating frequency of the stirring component 40 can be precisely controlled and adjusted, so that the working state of the refrigeration component 30 and the stirring component 40 is adapted to the current water outlet flow rate and the current water storage temperature. In this way, while preventing icing during the refrigeration process, the energy consumption of the drinking water equipment is reduced.

[0042] Optionally, in the above embodiments of this utility model, the motor controller 71 and the signal controller 72 can transmit data via a CAN bus. The signal controller 72 can send instructions to the motor controller 71 to control the refrigeration component 30 and the stirring component 40. At the same time, the motor controller 71 can feed back the status information of the refrigeration component 30 and the stirring component 40 to the signal controller 72 via the CAN bus, so that the signal controller 72 can adjust the control strategy accurately and efficiently, thereby improving the reliability of the control component 70.

[0043] Furthermore, in some examples of this utility model, such as Figure 3As shown, the refrigeration assembly 30 includes: a microchannel condenser 31, a built-in evaporator 32, and a variable frequency compressor 33.

[0044] The microchannel condenser 31 is configured to exchange heat with the outside environment; the built-in evaporator 32 is arranged around the axis of the cold water storage tank 10 and is configured to exchange heat with the water stored in the cold water storage tank 10; the variable frequency compressor 33 is connected to the microchannel condenser 31 and the built-in evaporator 32 respectively, and the variable frequency compressor 33 is configured to drive the microchannel condenser 31 and the built-in evaporator 32 to cool the water stored in the cold water storage tank 10.

[0045] It is understood that in this example of the present invention, the microchannel condenser 31, the built-in evaporator 32, and the variable frequency compressor 33 are interconnected. The variable frequency compressor 33 can drive the microchannel condenser 31 and the built-in evaporator 32 to cool the water stored in the cold water tank 10. Specifically, the refrigerant is compressed in the variable frequency compressor 33 and then flows to the microchannel condenser 31. After being compressed, the refrigerant exchanges heat with the outside through the microchannel condenser 31 (heat dissipation and cooling) and then flows to the built-in evaporator 32 to provide cooling capacity. The built-in evaporator 32, which is arranged around the axis of the cold water tank 10, exchanges heat with the water stored in the cold water tank 10 to reduce the water temperature in the cold water tank 10, thereby realizing the cooling of the water stored in the cold water tank 10.

[0046] Furthermore, in some examples of this utility model, the refrigeration assembly further includes a throttling element disposed between the microchannel condenser 31 and the built-in evaporator 32.

[0047] It is understood that in this example of the present invention, a throttling element is also provided between the microchannel condenser 31 and the built-in evaporator 32. The throttling element can be used to adjust the refrigerant flow rate, thereby adjusting the heat exchange capacity of the microchannel condenser 31 and the built-in evaporator 32.

[0048] Optionally, in the above examples of this utility model, the throttling element can be a capillary tube.

[0049] Furthermore, in some examples of this utility model, such as Figure 3 As shown, the refrigeration assembly 30 also includes an axial fan 34, which is disposed below the microchannel condenser 31.

[0050] It is understood that, in this example of the present invention, as Figure 3As shown, the refrigeration assembly 30 also includes an axial fan 34 disposed below the microchannel condenser 31. The air outlet of the axial fan 34 is directed toward the microchannel condenser 31. The axial fan 34 generates airflow by rotating its blades to rapidly cool and liquefy the gaseous refrigerant in the microchannel condenser 31, thereby achieving auxiliary heat dissipation for the microchannel condenser 31.

[0051] Furthermore, in some examples of this utility model, such as Figure 3 As shown, the stirring assembly 40 includes: stirring blades 41 and stirring motor 42.

[0052] The stirring blade 41 is configured to stir the water stored in the cold water tank 10; the stirring motor 42 is connected to the stirring blade 41 and is configured to drive the stirring blade 41 to rotate.

[0053] It is understood that, in this example of the present invention, as Figure 3 As shown, the stirring assembly 40 is installed inside the cold storage tank 10 and stirs the water stored in the cold storage tank 10 to make the water store cold evenly. The stirring assembly 40 includes stirring blades 41 for stirring the water stored in the cold storage tank 10 and stirring motor 42 for driving the stirring blades 41 to rotate.

[0054] Specifically, in some examples of this utility model, such as Figure 3 As shown, the stirring assembly 40 includes a stirring motor 41 and stirring blades 42. During the operation of the stirring assembly 40, the stirring motor 41 drives the stirring blades 42 to rotate at a preset frequency so that the stirring blades 42 stir the water stored in the cold water storage tank 10. This achieves uniform cooling of the stored water and effectively prevents local freezing caused by rapid cooling in the cold water storage tank 10.

[0055] Furthermore, in some examples of this utility model, the water outlet pipe 20 is arranged around the axis of the stirring motor 42.

[0056] It is understood that, in this example of the present invention, as Figure 4 As shown, the built-in evaporator 32 is arranged around the axis of the cold water storage tank 10, and the water outlet pipe 20 is arranged around the axis of the stirring motor 42. This achieves uniform cold storage of the water stored in the cold water storage tank 10 and uniform cooling of the water outlet pipe 20. Thus, while ensuring that the drinking water equipment provides cold water to users, it effectively prevents icing during the cooling process, enabling the drinking water equipment to achieve the best performance and water dispensing experience.

[0057] Furthermore, in some examples of this utility model, the cooling water system 1000 further includes a water level detection component 80, which is configured to detect the water level of the cold water storage tank 10.

[0058] Specifically, in this embodiment, the cooling water system 1000 further includes a water level detection component 80, which is disposed in the cold water storage tank 10. The water level detection component 80 is configured to detect the water level in the cold water storage tank 10. The water level detection component 80 is preferably a float ball, which can detect the water level in the cold water storage tank 10 to ensure that the water level is always maintained at an appropriate level. This ensures that the drinking water equipment can stably provide cold water to users. In addition, it can prevent damage to related equipment and improve the safety of the drinking water equipment. Furthermore, this utility model does not impose specific limitations on the selection of the water level detection component 80.

[0059] Furthermore, in some examples of this utility model, the cold water storage tank 10 includes a tank body 11 and an outer shell 12, with a thermal insulation medium 13 filling the space between the tank body 11 and the outer shell 12.

[0060] Specifically, in this embodiment, a thermal insulation medium 13 is filled between the outer shell 11 and the inner tank 12 of the cold water storage tank 10. The thermal insulation medium 13 can be thermal insulation foam, rock wool board, or glass wool board, etc. Furthermore, this invention does not impose specific limitations on the selection of the thermal insulation medium 13. This improves the thermal insulation performance of the cold water storage tank 10, achieving the goal of energy saving and consumption reduction.

[0061] In summary, the cooling water circuit system of the drinking water equipment according to this utility model example controls the cooling component and the stirring component to work in corresponding working states according to the temperature detected by the temperature detection element and the flow rate detected by the water outlet detection element, thereby preventing icing during the cooling process and reducing the energy consumption of the drinking water equipment.
