[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 the present invention, and should not be construed as limiting the present invention.

[0031] The following description, with reference to the accompanying drawings, describes a control method for a drinking water device, a computer-readable storage medium, a control device for a drinking water device, and a drinking water device according to embodiments of the present invention.

[0032] Specifically, in some embodiments of the present invention, such as Figure 1 As shown, the drinking water equipment 1000 includes a refrigeration device 100, a stirring device 200, and a cold water storage tank 300. The refrigeration device 100 is used to refrigerate the water stored in the cold water storage tank 300, and the stirring device 200 is used to stir the water stored in the cold water storage tank 300.

[0033] It is understood that in this embodiment of the present invention, the water stored in the cold storage tank 300 after being cooled by the refrigeration device 100 exchanges heat with the water supplied in the water supply pipeline to ensure that the drinking water equipment provides users with a stable supply of cold water. At the same time, the water stored in the cold storage tank 300 is stirred by the stirring device 200, which can effectively prevent freezing during the refrigeration process, so that the drinking water equipment can achieve the best performance and water dispensing experience.

[0034] Optionally, in the above embodiments of the present invention, the drinking water device 1000 can be an instant cold water dispenser.

[0035] More specifically, in some embodiments of the present invention, such as Figure 2 As shown, the refrigeration device includes a variable frequency compressor and an internal heat exchanger, and the stirring device includes a stirring motor and stirring blades. The variable frequency compressor is adapted to drive the internal heat exchanger to cool the water stored in the cold water storage tank, and the stirring motor is adapted to drive the stirring blades to stir the water stored in the cold water storage tank.

[0036] It is understood that in this embodiment of the invention, a variable frequency compressor pumps circulating refrigerant to the internal heat exchanger, allowing for extensive heat exchange between the refrigerant and the water in the cold water storage tank. This gradually lowers the temperature of the water in the tank. Simultaneously, a stirring motor controls the rotation of the stirring blades to agitate the water in the tank, ensuring a uniform temperature distribution. Therefore, while ensuring a stable supply of cold water to users, the water supply system effectively prevents icing during the cooling process, achieving optimal performance and a superior water dispensing experience.

[0037] Optionally, in the above embodiments of the present invention, the variable frequency compressor achieves heat exchange between the refrigerant and the outside through a microchannel condenser. An auxiliary heat exchange device is also provided below the microchannel condenser to enable the refrigerant in the microchannel condenser to be rapidly cooled and liquefied. In addition, the outer shell of the cold water storage tank is filled with insulation material to further improve the insulation capacity of the cold water storage tank.

[0038] Furthermore, other components and functions of the drinking water device in the embodiments of the present invention are known to those skilled in the art, and will not be described in detail here to reduce redundancy.

[0039] Figure 3 This is a flowchart illustrating the control method for a drinking water device according to an embodiment of the present invention.

[0040] Specifically, in some embodiments of the present invention, such as Figure 3 As shown, the control methods for the water dispenser include:

[0041] S101, obtain the water temperature in the cold water storage tank.

[0042] It is understood that, in this embodiment of the present invention, the water temperature in the cold water tank is monitored in real time by installing a cold water NTC in the cold water tank.

[0043] S102, determine the operating parameters of the refrigeration device and the stirring device based on the water temperature in the cold water storage tank.

[0044] It is understood that in this embodiment of the present invention, the operating parameters of the refrigeration device and the stirring device are dynamically adjusted by the water temperature in the cold water tank, so as to achieve precise control of the refrigeration device and the stirring device for different water temperatures, thereby improving the stability of the water outlet temperature of the drinking water equipment.

[0045] S103 controls the operation of the refrigeration unit and the stirring unit according to their operating parameters.

[0046] It is understood that in this embodiment of the present invention, the cooling device is controlled to operate with corresponding parameters to cool the water stored in the cold water tank, and the stirring device is controlled to operate with corresponding parameters to stir the water stored in the cold water tank. Therefore, while ensuring that the drinking water equipment provides users with a stable supply of cold water, it can also effectively prevent icing during the cooling process, enabling the drinking water equipment to achieve optimal performance and water dispensing experience.

[0047] It should be noted that, in the above embodiments of the present invention, after the water dispenser is powered on and the cooling function is turned on, the cooling device can be controlled to start cooling after waiting for a preset protection time, thereby improving the service life of the cooling device and ensuring the stability and reliability of the water dispenser.

[0048] Furthermore, in some embodiments of the present invention, such as Figure 4 As shown, based on the water temperature in the cold water tank, the operating parameters of the refrigeration unit and the stirring unit are determined, including:

[0049] S201, if the water temperature in the cold water tank is greater than the first preset temperature threshold, then the operating parameter of the variable frequency compressor is determined to be the first operating frequency.

[0050] It is understood that in this embodiment of the present invention, when the water temperature in the cold storage tank is greater than the first preset temperature threshold, it can be considered that the water in the cold storage tank needs to be cooled quickly. At this time, the operating parameter of the variable frequency compressor is determined to be the first operating frequency. Specifically, when the water temperature in the cold storage tank is greater than the first preset temperature threshold, the variable frequency compressor is controlled to work at the first operating frequency (high frequency).

[0051] Optionally, in the above embodiments of the present invention, the first preset temperature threshold can be set according to the cold storage capacity of the cold water tank. For example, the first preset temperature threshold can preferably be 10°C, and the first operating frequency can be set according to the cooling capacity of the refrigeration device. For example, the first operating frequency can preferably be 4200 rpm.

[0052] S202, if the water temperature in the cold water storage tank is greater than the second preset temperature threshold and less than or equal to the first preset temperature threshold, then the operating parameter of the variable frequency compressor is determined to be the second operating frequency, and the operating parameter of the stirring motor is determined to be the first operating frequency, wherein the second operating frequency is less than the first operating frequency.

[0053] It is understood that in this embodiment of the present invention, when the water temperature in the cold storage tank is greater than the second preset temperature threshold and less than or equal to the first preset temperature threshold, it can be considered that the initial cold storage in the cold storage tank has been completed. At this time, the operating parameters of the variable frequency compressor are determined to be the second operating frequency and the operating parameters of the stirring motor are determined to be the first operating frequency. Specifically, when the water temperature in the cold storage tank is greater than the second preset temperature threshold and less than or equal to the first preset temperature threshold, the variable frequency compressor is controlled to operate at the second operating frequency (medium frequency) and the stirring motor is controlled to operate at the first operating frequency, wherein the second operating frequency is less than the first operating frequency.

[0054] It should be noted that adjusting the operating frequency of the variable frequency compressor from the first operating frequency to the second operating frequency can further reduce the power consumption of the water dispenser, thereby achieving energy conservation and emission reduction.

[0055] Optionally, in the above embodiments of the present invention, the second preset temperature threshold can be set according to the cold storage capacity of the cold water tank. For example, the second preset temperature threshold can preferably be 5°C. The second operating frequency can be set according to the cooling capacity of the refrigeration device. For example, the second operating frequency can preferably be 3500 rpm. The first operating frequency can be set according to the stirring capacity of the stirring device. For example, the first operating frequency can preferably be started and stopped synchronously with the variable frequency compressor.

[0056] Furthermore, in some embodiments of the present invention, such as Figure 4 As shown, the operating parameters of the refrigeration unit and the stirring unit are determined based on the water temperature in the cold water storage tank, and also include:

[0057] S203, if the water temperature in the cold water tank is greater than the third preset temperature threshold and less than or equal to the second preset temperature threshold, then the operating parameter of the variable frequency compressor is determined to be the third operating frequency, and the operating parameter of the stirring motor is determined to be the second operating frequency, wherein the third operating frequency is less than the second operating frequency, and the second operating frequency is less than the first operating frequency.

[0058] It is understood that in this embodiment of the present invention, when the water temperature in the cold storage tank is greater than the third preset temperature threshold and less than or equal to the second preset temperature threshold, it can be considered that the water in the cold storage tank has completed medium-level cooling. At this time, the operating parameters of the variable frequency compressor are determined to be the third operating frequency and the operating parameters of the stirring motor are determined to be the second operating frequency. Specifically, when the water temperature in the cold storage tank is greater than the third preset temperature threshold and less than or equal to the second preset temperature threshold, the variable frequency compressor is controlled to operate at the third operating frequency (medium-low frequency) and the stirring motor is controlled to operate at the second operating frequency. The third operating frequency is less than the second operating frequency and the second operating frequency is less than the first operating frequency.

[0059] It should be noted that adjusting the operating frequency of the variable frequency compressor from the second operating frequency to the third operating frequency, and adjusting the operating frequency of the stirring motor from the first operating frequency to the second operating frequency, can further reduce the power consumption of the water supply equipment and achieve energy conservation and emission reduction.

[0060] Optionally, in the above embodiments of the present invention, the third preset temperature threshold can be set according to the cold storage capacity of the cold water tank. For example, the third preset temperature threshold can preferably be 1°C. The third operating frequency can be set according to the cooling capacity of the refrigeration device. For example, the third operating frequency can preferably be 2800 rpm. The second operating frequency can be set according to the stirring capacity of the stirring device. For example, the second operating frequency can preferably be 4 minutes on and 1 minute off.

[0061] S204, if the water temperature in the cold water tank is greater than the fourth preset temperature threshold and less than or equal to the third preset temperature threshold, then the operating parameter of the variable frequency compressor is determined to be the fourth operating frequency, and the operating parameter of the stirring motor is determined to be the third operating frequency, wherein the fourth operating frequency is less than the third operating frequency, and the third operating frequency is less than the second operating frequency.

[0062] It is understood that in this embodiment of the present invention, when the water temperature in the cold storage tank is greater than the fourth preset temperature threshold and less than or equal to the third preset temperature threshold, it can be considered that the water in the cold storage tank has completed high-level cooling. At this time, the operating parameter of the variable frequency compressor is determined to be the fourth operating frequency, and the operating parameter of the stirring motor is determined to be the third operating frequency. Specifically, when the water temperature in the cold storage tank is greater than the fourth preset temperature threshold and less than or equal to the third preset temperature threshold, the variable frequency compressor is controlled to operate at the fourth operating frequency (low frequency), and the stirring motor is controlled to operate at the third operating frequency. The fourth operating frequency is less than the third operating frequency, and the third operating frequency is less than the second operating frequency.

[0063] It should be noted that adjusting the operating frequency of the variable frequency compressor from the third operating frequency to the fourth operating frequency, and adjusting the operating frequency of the stirring motor from the second operating frequency to the third operating frequency, can further reduce the power consumption of the drinking water equipment and achieve energy conservation and emission reduction.

[0064] Optionally, in the above embodiments of the present invention, the fourth preset temperature threshold can be set according to the cold storage capacity of the cold water tank. For example, the fourth preset temperature threshold can preferably be -2.5℃. The fourth operating frequency can be set according to the cooling capacity of the refrigeration device. For example, the fourth operating frequency can preferably be 2000rpm. The third operating frequency can be set according to the stirring capacity of the stirring device. For example, the second operating frequency can preferably be 2 minutes on and 1 minute off.

[0065] Furthermore, in some embodiments of the present invention, the first operating frequency range is [4000rpm, 4400rpm], the second operating frequency range is [3300rpm, 3700rpm], the third operating frequency range is [2600rpm, 3000rpm], and the fourth operating frequency range is [1800rpm, 2200rpm].

[0066] It is understood that, in this embodiment of the present invention, any operating frequency can be selected from the high frequency range [4000rpm, 4400rpm] as the first operating frequency, any operating frequency can be selected from the mid frequency range [3300rpm, 3700rpm] as the second operating frequency, any operating frequency can be selected from the mid-low frequency range [2600rpm, 3000rpm] as the third operating frequency, and any operating frequency can be selected from the low frequency range [1800rpm, 2200rpm] as the fourth operating frequency.

[0067] Furthermore, in some embodiments of the present invention, the method further includes: if the water temperature in the cold water tank reaches a fourth preset temperature threshold, then controlling the variable frequency compressor to stop.

[0068] It is understood that in this embodiment of the present invention, when the water temperature in the cold storage tank reaches the fourth preset temperature threshold, it can be considered that the water in the cold storage tank has completed cooling. At this time, the variable frequency compressor can be stopped to allow the cold storage tank to enter the heat preservation state.

[0069] Furthermore, in some embodiments of the present invention, after controlling the variable frequency compressor to stop, the method further includes: if the water temperature in the cold water tank is greater than a third preset temperature threshold, then controlling the variable frequency compressor to start running.

[0070] It is understood that in this embodiment of the present invention, after the variable frequency compressor is stopped, when the water in the cold storage tank stably recovers to above the third preset temperature threshold, it can be considered that the water temperature in the cold storage tank has risen to the state required for cold storage. At this time, the variable frequency compressor can be started to run, so that the water in the cold storage tank enters a new round of cold storage.

[0071] The following is combined with Figure 5 With reference to specific embodiments of the present invention, the frequency conversion and stirring / mixing water cooling process of the control method for the drinking water equipment of the present invention will be described accordingly. For example, as follows: Figure 5 As shown, after the water dispenser is powered on and the cooling function is turned on, step S1 is executed.

[0072] S1 controls the variable frequency compressor to restart after a 3-minute protection period.

[0073] S2, when the water storage temperature is >10℃, the variable frequency compressor runs at a high frequency of 4200rpm; when 5℃ < water storage temperature ≤10℃, the variable frequency compressor runs at a medium frequency of 3500rpm, and the stirring motor starts and stops synchronously with the variable frequency compressor; when 1℃ < water storage temperature ≤5℃, the variable frequency compressor runs at a medium-low frequency of 2800rpm, and the stirring motor runs at a frequency of 4 minutes on and 1 minute off; when -2.5℃ < water storage temperature ≤1℃, the variable frequency compressor runs at a low frequency of 2000rpm, and the stirring motor runs at a frequency of 2 minutes on and 1 minute off.

[0074] S3, when the water storage temperature is -2.5℃, the variable frequency compressor stops and the cold water tank enters the heat preservation state.

[0075] S4. If the water storage temperature is >1℃, return to step S2.

[0076] In summary, the control method for the drinking water equipment according to embodiments of the present invention obtains the water temperature in the cold water storage tank, then determines the operating parameters of the refrigeration device and the stirring device based on the water temperature in the cold water storage tank, and controls the refrigeration device and the stirring device to operate based on the operating parameters of the refrigeration device and the stirring device. Therefore, by dynamically adjusting the operating parameters of the refrigeration device and the stirring device, precise temperature control of the water temperature in the cold water storage tank is achieved. This ensures that the drinking water equipment provides a stable supply of cold water to users while effectively preventing icing during the refrigeration process, thus enabling the drinking water equipment to achieve optimal performance and water dispensing experience.

[0077] Based on the control method of the drinking water device in the foregoing embodiments of the present invention, the present invention proposes a computer-readable storage medium storing a control program for the drinking water device thereon. When the control program for the drinking water device is executed by a processor, it implements the control method of the drinking water device in the foregoing embodiments of the present invention.
