[0030] 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.

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

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

[0033] It can be understood that in this embodiment of the present invention, the water stored in the cold water tank 300 after being refrigerated by the refrigeration device 100 is heat exchanged with the water supply in the water supply pipeline to ensure that the drinking water equipment can stably provide cold water to the user. At the same time, the water stored in the cold water tank 300 is stirred by the stirring device 200, which can effectively prevent freezing from occurring during the refrigeration process, so that the drinking water equipment can achieve the best performance effect and water output experience.

[0034] Optionally, in the above embodiment of the present invention, the drinking water device 1000 may be an instant cooling water dispenser.

[0035] More specifically, in some embodiments of the present invention, Figure 2As shown, the refrigeration device includes a variable frequency compressor and a built-in heat exchanger, and the stirring device includes a stirring motor and stirring blades. The variable frequency compressor is suitable for driving the built-in heat exchanger to cool the water in the cold storage water tank, and the stirring motor is suitable for driving the stirring blades to stir the water in the cold storage water tank.

[0036] It is understandable that in this embodiment of the present invention, the variable frequency compressor is used to pump circulating refrigerant to the built-in heat exchanger, so that a large amount of heat is exchanged with the water in the cold water tank through the built-in heat exchanger, so that the temperature of the water in the cold water tank is gradually reduced. At the same time, the stirring blade is controlled by the stirring motor to rotate to stir the water in the cold water tank, so that the temperature of the water in the cold water tank is evenly distributed. In this way, while ensuring that the drinking water equipment can stably provide cold water to users, it can also effectively prevent ice from occurring during the refrigeration process, so that the drinking water equipment can achieve the best performance effect and water output experience.

[0037] Optionally, in the above-mentioned embodiment of the present invention, the variable frequency compressor realizes heat exchange between the refrigerant and the outside world through a microchannel condenser, and an auxiliary heat exchange device is also arranged under the microchannel condenser to quickly cool and liquefy the refrigerator in the microchannel condenser, and the outer shell of the cold storage water tank is filled with thermal insulation material to further improve the thermal insulation capacity of the cold storage water tank.

[0038] In addition, other structures and functions of the drinking water device in the embodiment 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 4 is a flow chart of an energy-saving control method for a drinking water device according to an embodiment of the present invention.

[0040] Specifically, in some embodiments of the present invention, Figure 3 As shown, the energy-saving control method of the drinking water equipment includes:

[0041] S101, obtaining an operation mode of a drinking water device, wherein the operation mode includes a normal cooling operation mode and an ECO cooling operation mode.

[0042] It can be understood that in this embodiment of the present invention, the normal refrigeration operation mode focuses on making the refrigeration device operate efficiently, thereby quickly cooling the water stored in the cold water tank and promptly responding to the user's water demand. The ECO refrigeration operation mode focuses on making the refrigeration device operate with low power consumption, thereby reducing the energy consumption of drinking water equipment while achieving precise temperature control of the water stored in the cold water tank.

[0043] It should be noted that, in the above-mentioned embodiment of the present invention, the operation mode of the drinking water device can be switched between the normal cooling operation mode and the ECO cooling operation mode based on the actual working scenario of the drinking water device.

[0044] S102, obtaining the water temperature in the cold water storage tank, and determining the operating parameters of the refrigeration device and the stirring device according to the operation mode and the water temperature.

[0045] It can be understood that in this embodiment of the present invention, a cold water NTC is set in the cold water tank to monitor the water temperature in the cold water tank in real time. Then, combined with the operation mode of the drinking water equipment and the water temperature in the cold water tank, the working parameters of the refrigeration device and the stirring device are dynamically adjusted 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.

[0046] S103, controlling the refrigeration device and the stirring device to operate according to the operating parameters of the refrigeration device and the stirring device.

[0047] It can be understood that in this embodiment of the present invention, the cooling of the water stored in the cold water tank is achieved by controlling the refrigeration device to operate with corresponding working parameters, and the stirring of the water stored in the cold water tank is achieved by controlling the stirring device to operate with corresponding working parameters.

[0048] Furthermore, in some embodiments of the present invention, the operating mode of the drinking water equipment is obtained, including: if a water usage signal is detected, determining the operating mode of the drinking water equipment to be a normal refrigeration operating mode; and if no water usage signal is detected and continues for a first preset time, determining the operating mode of the drinking water equipment to be an ECO refrigeration operating mode.

[0049] It can be understood that in this embodiment of the present invention, when a water usage signal is detected, it can be judged that the user currently has a water demand. At this time, the operation mode of the drinking water equipment is determined to be the normal refrigeration operation mode to control the refrigeration device to operate with high efficiency. Moreover, when no water usage signal is detected and it lasts for the first preset time, it can be judged that the user currently has no water demand. At this time, the operation mode of the drinking water equipment is determined to be the ECO refrigeration operation mode to control the refrigeration device to operate with low power consumption.

[0050] Optionally, in the above-mentioned embodiment of the present invention, the first preset time may be set accordingly according to actual needs. For example, the first preset time may preferably be 24 hours.

[0051] Further, in some embodiments of the present invention, Figure 4 As shown, after the operation mode of the drinking water equipment is determined to be the normal refrigeration operation mode, the working parameters of the refrigeration device and the stirring device are determined according to the operation mode and the water storage temperature, including:

[0052] S201: If the water temperature in the cold water storage tank is greater than a first preset temperature threshold, determining that the operating parameter of the variable frequency compressor is a first operating frequency.

[0053] It can be understood that in this embodiment of the present invention, when the drinking water equipment is operating in the normal cooling operation mode, when the water storage temperature in the cold water tank is greater than the first preset temperature threshold, it can be considered that the water in the cold water tank needs to be quickly cooled. At this time, the working parameter of the variable frequency compressor is determined to be the first operating frequency. Specifically, when the water storage temperature in the cold water tank is greater than the first preset temperature threshold, the variable frequency compressor is controlled to operate at the first operating frequency (high frequency).

[0054] Optionally, in the above-mentioned embodiments of the present invention, the first preset temperature threshold can be set accordingly according to the cold storage capacity of the cold storage water tank. For example, the first preset temperature threshold can be preferably 10°C, and the first operating frequency can be set accordingly according to the refrigeration capacity of the refrigeration device. For example, the first operating frequency can be preferably 4200rpm.

[0055] S202, if the water temperature in the cold water tank is greater than the second preset temperature threshold and less than or equal to the first preset temperature threshold, the working parameters of the variable frequency compressor are determined to be the second operating frequency, and the working parameters of the stirring motor are determined to be the first operating frequency, wherein the second operating frequency is less than the first operating frequency.

[0056] It can be understood that in this embodiment of the present invention, during the operation of the drinking water equipment in the normal refrigeration operation mode, when the water storage temperature in the cold water 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 water storage in the cold water tank has completed the initial cold storage. At this time, the working parameters of the variable frequency compressor are determined to be the second operating frequency, and the working parameters of the stirring motor are determined to be the first operating frequency. Specifically, when the water storage temperature in the cold water 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.

[0057] 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 drinking water equipment and achieve energy conservation and emission reduction.

[0058] Optionally, in the above-mentioned embodiments of the present invention, the second preset temperature threshold can be set accordingly according to the cold storage capacity of the cold storage water tank, for example, the second preset temperature threshold can be preferably 5°C, and the second operating frequency can be set accordingly according to the refrigeration capacity of the refrigeration device, for example, the second operating frequency can be preferably 3500rpm, and the first operating frequency can be set accordingly according to the stirring capacity of the stirring device, for example, the first operating frequency can be preferably started and stopped synchronously with the variable frequency compressor.

[0059] Further, in some embodiments of the present invention, Figure 4 As shown, according to the operation mode and the water storage temperature, the working parameters of the refrigeration device and the stirring device are determined, and also include:

[0060] 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, the working parameters of the variable frequency compressor are determined to be the third operating frequency, and the working parameters of the stirring motor are 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.

[0061] It can be understood that in this embodiment of the present invention, during the operation of the drinking water equipment in the normal refrigeration operation mode, when the water storage 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, it can be considered that the water storage in the cold water tank has completed moderate refrigeration. At this time, the working parameters of the variable frequency compressor are determined to be the third operating frequency, and the working parameters of the stirring motor are determined to be the second operating frequency. Specifically, when the water storage 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, the variable frequency compressor is controlled to operate at the third operating frequency (medium and low frequency), and the stirring motor is controlled to operate at 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.

[0062] It should be noted that the operating frequency of the variable frequency compressor is adjusted from the second operating frequency to the third operating frequency, and the operating frequency of the stirring motor is adjusted from the first operating frequency to the second operating frequency, which can further reduce the power consumption of the drinking water equipment and achieve energy conservation and emission reduction.

[0063] Optionally, in the above embodiments of the present invention, the third preset temperature threshold can be set accordingly according to the cold storage capacity of the cold storage water tank, for example, the third preset temperature threshold can be preferably 1°C, and the third operating frequency can be set accordingly according to the refrigeration capacity of the refrigeration device, for example, the third operating frequency can be preferably 2800rpm, and the second operating frequency can be set accordingly according to the stirring capacity of the stirring device, for example, the second operating frequency can be preferably turned on for 4 minutes and stopped for 1 minute.

[0064] 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, the working parameters of the variable frequency compressor are determined to be the fourth operating frequency, and the working parameters of the stirring motor are 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.

[0065] It can be understood that in this embodiment of the present invention, during the operation of the drinking water equipment in the normal refrigeration operation mode, when the water storage 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, it can be considered that the water storage in the cold water tank has completed high-level refrigeration. At this time, the working parameters of the variable frequency compressor are determined to be the fourth operating frequency, and the working parameters of the stirring motor are determined to be the third operating frequency. Specifically, when the water storage 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, 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, wherein the fourth operating frequency is less than the third operating frequency, and the third operating frequency is less than the second operating frequency.

[0066] It should be noted that the operating frequency of the variable frequency compressor is adjusted from the third operating frequency to the fourth operating frequency, and the operating frequency of the stirring motor is adjusted from the second operating frequency to the third operating frequency, which can further reduce the power consumption of the drinking water equipment and achieve energy conservation and emission reduction.

[0067] Optionally, in the above embodiments of the present invention, the fourth preset temperature threshold can be set accordingly according to the cold storage capacity of the cold storage water tank, for example, the fourth preset temperature threshold can be preferably -2.5°C, and the fourth operating frequency can be set accordingly according to the refrigeration capacity of the refrigeration device, for example, the fourth operating frequency can be preferably 2000rpm, and the third working frequency can be set accordingly according to the stirring capacity of the stirring device, for example, the second working frequency can be preferably turned on for 2 minutes and stopped for 1 minute.

[0068] Furthermore, in some embodiments of the present invention, the method further includes: if the water temperature in the cold storage water tank reaches a fourth preset temperature threshold, controlling the variable frequency compressor to stop.

[0069] It can be understood that in this embodiment of the present invention, when the water temperature in the cold water tank reaches the fourth preset temperature threshold, it can be considered that the water in the cold water tank has completed cooling. At this time, the variable frequency compressor can be controlled to stop, so that the cold water tank enters the insulation state.

[0070] Further, in some embodiments of the present invention, Figure 5As shown, after the operation mode of the drinking water equipment is determined to be the ECO refrigeration operation mode, the working parameters of the refrigeration device and the stirring device are determined according to the operation mode and the water storage temperature, including:

[0071] S301: If the water temperature in the cold water storage tank is greater than or equal to the energy-saving temperature upper limit threshold, determine that the working parameter of the variable frequency compressor is a fifth operating frequency.

[0072] It can be understood that in this embodiment of the present invention, when the drinking water equipment is operating in the ECO refrigeration operation mode, when the water storage temperature in the cold water tank is greater than or equal to the energy-saving temperature upper limit threshold, it can be considered that the water storage temperature of the cold water tank has risen to a state where cold storage is required. At this time, the working parameter of the variable frequency compressor is determined to be the fifth operating frequency.

[0073] Optionally, in the above-mentioned embodiments of the present invention, the energy-saving temperature upper limit threshold can be set accordingly according to the cold storage capacity of the cold storage water tank. For example, the energy-saving temperature upper limit threshold can be preferably 4°C, and the fifth operating frequency can be set accordingly according to the refrigeration capacity of the refrigeration device. For example, the fifth operating frequency can be preferably 2000rpm.

[0074] S302: If the water temperature in the cold water storage tank is less than or equal to the lower limit threshold of the energy-saving temperature, the variable frequency compressor is controlled to stop.

[0075] It can be understood that in this embodiment of the present invention, when the drinking water equipment is operating in the ECO refrigeration operation mode, when the water storage temperature in the cold water tank is greater than or equal to the energy-saving temperature upper limit threshold, it can be considered that the water storage in the cold water tank has completed cooling. At this time, the variable frequency compressor can be controlled to stop, so that the cold water tank enters the insulation state.

[0076] Optionally, in the above embodiment of the present invention, the lower limit threshold of the energy-saving temperature may be set accordingly according to the cold storage capacity of the cold storage water tank. For example, the lower limit threshold of the energy-saving temperature may preferably be 1°C.

[0077] Combine the following Figure 6 In accordance with the specific embodiment of the present invention, the energy-saving process of the energy-saving control method of the drinking water equipment in the embodiment of the present invention is described accordingly. For example, Figure 6 As shown, after the drinking water device is powered on and the cooling function is turned on, step S1 is executed.

[0078] S1, controls the variable frequency compressor to restart after 3 minutes of protection.

[0079] S2, when the water storage temperature is greater than 10℃, the variable frequency compressor runs at a high-frequency speed of 4200rpm; when 5℃<water storage temperature≤10℃, the variable frequency compressor runs at a medium-frequency speed of 3500rpm, and the stirring motor and the variable frequency compressor start and stop synchronously; when 1℃<water storage temperature≤5℃, the variable frequency compressor runs at a medium-low frequency speed of 2800rpm, and the stirring motor runs at a frequency of starting for 4 minutes and stopping for 1 minute; when -2.5℃<water storage temperature≤1℃, the variable frequency compressor runs at a low-frequency speed of 2000rpm, and the stirring motor runs at a frequency of starting for 2 minutes and stopping for 1 minute.

[0080] S3, when the water storage temperature = -2.5℃, the variable frequency compressor stops and the cold water storage tank enters the insulation state.

[0081] S4, when the water storage temperature is greater than 1°C, determine whether no water use signal is received and whether it lasts for 24 hours. If yes, execute step S5; if not, return to execute step S2.

[0082] S5, when the water storage temperature is ≥4°C, the variable frequency compressor runs at a low frequency speed of 2000rpm, and when the water storage temperature is ≤1°C, the variable frequency compressor stops. When a water use signal is received, it returns to step S2.

[0083] It should be noted that, in some embodiments of the present invention, if no water usage signal is detected during the operation of the drinking water equipment in the normal refrigeration operation mode and the signal lasts for a first preset time, the operation mode of the drinking water equipment is switched from the normal refrigeration operation mode to the ECO refrigeration operation mode to reduce the energy consumption of the drinking water equipment. In addition, if a water usage signal is detected during the operation of the drinking water equipment in the ECO refrigeration operation mode, the operation mode of the drinking water equipment is switched from the ECO refrigeration operation mode to the normal refrigeration operation mode to timely respond to the user's water needs.

[0084] In addition, in some other embodiments of the present invention, the drinking water equipment can be controlled to first achieve complete cooling of the water stored in the cold water tank in normal refrigeration operation mode, and then the water usage signal detection can be started. Thus, after the cold storage demand of the cold water tank is preferentially met, the energy consumption of the drinking water equipment can be further reduced.

[0085] In summary, according to the energy-saving control method of the drinking water equipment according to the embodiment of the present invention, the operation mode of the drinking water equipment is obtained, wherein the operation mode includes the normal refrigeration operation mode and the ECO refrigeration operation mode, and then the water storage temperature in the cold water storage tank is obtained, and the working parameters of the refrigeration device and the stirring device are determined according to the operation mode and the water storage temperature, and the refrigeration device and the stirring device are controlled to work according to the working parameters of the refrigeration device and the stirring device. Therefore, by combining the operation mode of the drinking water equipment with the water storage temperature in the cold water storage tank, the dynamic adjustment of the working parameters of the refrigeration device and the stirring device is realized, so that the energy consumption of the drinking water equipment is reduced while realizing the precise temperature control of the water storage temperature in the cold water storage tank.

[0086] Based on the energy-saving control method for drinking water equipment of the aforementioned embodiment of the present invention, the embodiment of the present invention proposes a computer-readable storage medium, on which a control program for drinking water equipment is stored. When the control program for drinking water equipment is executed by a processor, the energy-saving control method for drinking water equipment of the aforementioned embodiment of the present invention is implemented.
