The drinking water equipment includes a cold water tank, a water supply pump and a refrigeration device.

[0008] The water drinking equipment includes a cold water tank, a water supply pump and a refrigerating device.

[0012] In some embodiments of the present application, the water drinking equipment further comprises an ice storage tank, a circulating pump and an ice making box. The ice storage tank is arranged above the cold water tank, the ice making box is arranged above the ice storage tank, the evaporator is arranged in the ice making box, the ice making box is provided with a flow guide groove, and the circulating pump is arranged between the cold water tank and the ice making box.

[0013] In some embodiments of the present invention, the method further includes: continuously acquiring the cold water temperature of the cold water tank when the refrigeration device is in the heat preservation operation mode; and controlling the refrigeration device and the circulation pump to operate when the cold water temperature is greater than a third preset temperature, until the cold water temperature is less than or equal to the second preset temperature, wherein the third preset temperature is greater than or equal to the second preset temperature.

[0014] In some embodiments of the present invention, the method further includes: when the water drinking device starts the cooling water operation, controlling the compressor to start operation after a third preset time delay.

[0015] To achieve the above objectives, a second aspect of the present invention provides a computer-readable storage medium storing a control program for a drinking water device thereon. When the control program for the drinking water device is executed by a processor, it implements the control method for the drinking water device described in any of the above embodiments.

[0016] The computer-readable storage medium of this invention executes the control program of the water drinking device stored thereon through a processor, which can ensure the smooth operation of the cooling water condition, improve the user's water experience, and at the same time ensure that the function of the water drinking device is not affected and extend the service life of the water drinking device.

[0017] To achieve the above objectives, a third aspect of the present invention provides a control device for a drinking water device.

Detailed Implementation

[0023] 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.

[0024] The following description, with reference to the accompanying drawings, describes the control method and apparatus for the drinking water equipment, the storage medium, and the drinking water equipment according to embodiments of the present invention.

[0025] Figure 1 This is a schematic diagram of a drinking water device according to an embodiment of the present invention.

[0026] like Figure 1 As shown, the drinking water equipment includes a water supply pump, an ice storage tank, a cold water tank, and a refrigeration unit, wherein, for example... Figure 2 As shown, the refrigeration unit includes an evaporator and a refrigerant solenoid valve. It should be noted that the water dispenser also includes other components, such as an ice maker, a circulation pump, an ice-making motor, and an ice-storage motor. For details, please refer to [link to relevant documentation]. Figure 1 The relevant description is provided, and the refrigeration unit may also include a condenser, compressor, capillary tube, dryer filter, cooling fan, etc. For details, see [link to relevant documentation]. Figure 2 After the high-temperature, high-pressure refrigerant generated by the compressor enters the condenser, it is cooled and condensed into a high-pressure liquid refrigerant by the cooling fan and airflow. This high-pressure liquid refrigerant is then processed through a dryer filter and capillary tube, causing a rapid pressure drop to form a low-temperature, low-pressure refrigerant that enters the evaporator. In the evaporator, the low-temperature, low-pressure refrigerant absorbs heat to complete the refrigeration operation before flowing back into the compressor to form a cycle. During this process, if the refrigerant solenoid valve is closed, the high-temperature, high-pressure refrigerant generated by the compressor will flow directly into the evaporator through the branch containing the refrigerant solenoid valve, thereby increasing the evaporator's temperature. See also... Figure 1The drinking water equipment contains room temperature drinking water in its water tank. A water pump can pump the room temperature drinking water in the water tank to a warm water tank. The warm water tank is equipped with a level sensor to detect the warm water level. When the warm water tank is full, the water in the warm water tank will be directed to a cold water tank. The cold water tank is also equipped with a level sensor to detect the cold water level. The warm water tank is also connected to a hot water tank. Gravity is used to guide the water in the warm water tank into the hot water tank. The hot water tank has a heating device (not shown in the figure) to perform heating operations. The steam generated by heating in the hot water tank can be discharged into the warm water tank. When the hot water valve is opened, the hot water in the hot water tank is also sent out through the hot water valve. When the cold water valve is opened, cold water from the cold water tank is also supplied through the valve. A circulation pump is installed between the cold water valve and the cold water tank to ensure the smooth supply of cold water. The circulation pump also pumps cold water from the cold water tank to the ice maker. The evaporator is located above the ice maker and cools the water in it. The cold water is then guided to the cold water tank through a guide channel on the ice maker. An ice storage tank is located below the ice maker. During the ice-making process, the ice-making motor controls the rotation of the ice maker, allowing the ice condensed on the evaporator to fall into the ice storage tank. A microswitch is used to position the ice maker accurately, ensuring smooth ice making and unfreezing. A water outlet is located at the bottom of the ice storage tank to guide the ice water into the cold water tank. The ice dispensing machine then dispenses the ice from the storage tank.

[0027] It should be noted that, Figure 1 The black arrows indicate the flow of drinking water during normal water use, while the red arrows indicate the flow of high-temperature water during high-temperature sterilization. See the arrow directions for details. Also see... Figure 3 and Figure 4 As shown, the drinking water device in this embodiment can also have other design configurations. The black arrows also indicate the direction of water flow. The usage of each component can be found in [reference needed]. Figure 1 The relevant descriptions will not be repeated here. It is understandable that... Figure 1 , Figure 3 and Figure 4 The water dispenser is also equipped with a door control switch, which can detect whether the lower door of the water dispenser is open. Specifically, the lower door can be opened when changing or adding water to the water bottle. At this time, the water dispenser can be put into standby mode to prevent the water dispenser's cooling water, ice making and other functions from malfunctioning.

[0028] Figure 5 This is a flowchart of a control method for a drinking water device in one embodiment of the present invention.

[0029] like Figure 5 As shown, the present invention proposes a control method for a drinking water device, which includes the following steps: S10: When the drinking water equipment starts the cooling water operation, obtain the cold water level in the cold water tank and the ambient temperature.

[0030] Specifically, after being powered on, the water dispenser in this embodiment can receive specific function commands. These commands can be received via buttons, control panels, remote control, etc. Upon receiving a cooling water command, the dispenser activates the cooling water mode. In cooling water mode, the water level information of the cold water tank and the ambient temperature can be acquired. Specifically, the water level information can be used to determine whether the cold water tank is full. More specifically, the water level information can be obtained via a float. Since ambient temperature affects the freezing rate of ice, this embodiment also acquires the ambient temperature to determine the freezing rate of ice on the evaporator, enabling more precise control in subsequent operations.

[0031] S20 controls the water supply pump to start when the cold water level is lower than the preset level, and controls the opening and closing of the refrigerant solenoid valve according to the ambient temperature. When the refrigerant solenoid valve is started, the high temperature and high pressure refrigerant generated by the compressor is directed to the evaporator, so that the ice attached to the evaporator melts and falls off.

[0032] Specifically, after obtaining the water level information, it can be determined whether the cold water in the cold water tank has completed the cooling operation. See details... Figure 1 , Figure 3 or Figure 4 As can be seen, the ice-making box is located above the ice storage tank. This embodiment does not need to describe the ice storage situation in the ice storage tank; specifically, it is sufficient to limit the condensation of large ice blocks on the evaporator during the cooling water process, thus preventing it from affecting the generation of cold water. Therefore, in this embodiment, when the water level in the cold water tank is determined to be lower than the preset water level based on the cold water level, the water supply pump is started to pump water from the water tank to the warm water tank, and then from the warm water tank to the cold water tank. At this time, the temperature in the cold water tank will increase due to the addition of warm water, requiring further cooling water operation. During the cooling water operation, it is also necessary to prevent ice blocks from condensing on the evaporator, or to prevent the ice blocks condensing on the evaporator from becoming too large. Therefore, this embodiment also incorporates the ambient temperature to control the opening and closing of the refrigerant solenoid valve, allowing the high-temperature, high-pressure refrigerant generated by the compressor to flow to the evaporator to heat the evaporator, thereby melting the ice blocks condensed on the evaporator and preventing large ice blocks from condensing on the evaporator, which would affect the evaporator's cooling water operation. In this embodiment, the opening and closing control of the refrigerant solenoid valve is combined with the ambient temperature, which can improve the control accuracy. When the ambient temperature is high, the freezing time is long, so the opening and closing control frequency of the refrigerant solenoid valve can be lower. When the ambient temperature is low, the freezing time is short, so the opening and closing control frequency of the refrigerant solenoid valve can be higher.

[0033] In some embodiments of the present invention, the refrigerant solenoid valve is controlled to open and close according to the ambient temperature, including: when the ambient temperature is greater than or equal to a first preset temperature, the refrigerant solenoid valve is controlled to open every first preset time interval, and the refrigerant solenoid valve is controlled to close after the ice attached to the evaporator is removed; when the ambient temperature is less than the first preset temperature, the refrigerant solenoid valve is controlled to open every second preset time interval, and the refrigerant solenoid valve is controlled to close after the ice attached to the evaporator is removed, wherein the first preset time interval is longer than the second preset time interval.

[0034] Specifically, taking a first preset temperature of 20 degrees Celsius, a first preset duration of 30 minutes, and a second preset duration of 15 minutes as an example, when the ambient temperature is greater than or equal to 20 degrees Celsius, it indicates a high ambient temperature and a longer evaporator freezing time. Therefore, the refrigerant solenoid valve can be opened every 30 minutes, while simultaneously checking whether the ice on the evaporator has fallen off. Once the ice on the evaporator melts and falls off, the refrigerant solenoid valve can be closed, and the cooling water operation can continue. Conversely, when the ambient temperature is less than 20 degrees Celsius, it indicates a low ambient temperature and a shorter evaporator freezing time. Therefore, the refrigerant solenoid valve can be opened every 15 minutes, while simultaneously checking whether the ice on the evaporator has melted and fallen off. If so, the refrigerant solenoid valve can be closed, and the cooling water operation can continue. It should be noted that the 20 degrees Celsius, 30 minutes, and 15 minutes in this embodiment are specific examples and are not practically limited. The specific values ​​can be determined based on actual operating conditions and the specifications of the water supply equipment.

[0035] In some embodiments of the present invention, the control method of the drinking water equipment further includes: obtaining the cold water level and cold water temperature of the cold water tank; controlling the water supply pump to stop running when the cold water level reaches a preset level; and controlling the refrigeration device to be in heat preservation operation mode when the cold water temperature is less than or equal to a second preset temperature.

[0036] Specifically, during the cooling process, the water level and temperature information of the cold water tank can be acquired. When the cold water level in the tank has not reached the preset level, it indicates that more cold water needs to be supplied. Therefore, the water supply pump can be controlled to supply water to the tank. If the cold water level in the tank reaches the preset level, it indicates that the tank is full, and the water supply pump can be stopped. Simultaneously, the water temperature in the tank can be monitored. If the water temperature is less than or equal to a second preset temperature, the cooling operation is complete, and further cooling is unnecessary. If the water temperature is greater than the second preset temperature, further cooling is required. In this case, the cooling unit and circulation pump can be controlled to operate until the water temperature is less than or equal to the second preset temperature. Optionally, the second preset temperature can be 5 degrees Celsius. It should be noted that since warm water is added to the cold water tank when the cold water level is insufficient, which will affect the cold water temperature, this embodiment can first determine the cold water level, and then determine the cold water temperature only when the cold water level meets the requirements. Of course, in other embodiments, to ensure the user's water temperature, the cold water temperature can be determined first, and then the cold water level can be determined only after the cold water temperature meets the requirements. When both the cold water level and the cold water temperature meet the requirements, the cold water device can be controlled to enter the heat preservation operation mode to keep the cold water in the cold water tank warm, ensuring that the cold water provided to the user reaches the second preset temperature, thus improving the user's cold water experience.

[0037] In some embodiments of the present invention, the drinking water device further includes a cooling water indicator light, and the control method further includes: when the drinking water device starts cooling water operation, controlling the cooling water indicator light to flash at a preset frequency; and when the cooling device is in heat preservation operation mode, controlling the cooling water indicator light to stay on.

[0038] Specifically, the water dispenser in this embodiment is also equipped with a cooling water indicator light. This indicator light can show the status information of the water dispenser. When the water dispenser is in cooling water mode, the cooling water indicator light can be controlled to flash at a preset frequency. Optionally, this preset frequency can be once per second, indicating that the water dispenser is in cooling water mode. When the cooling device is in heat preservation mode, the cooling water indicator light can be controlled to remain on, indicating that the current cooling water operation is complete and the cold water in the cold water tank meets the user's drinking water temperature requirements, thus allowing the user to easily understand the status of the water dispenser.

[0039] In some embodiments of the present invention, the control method of the drinking water equipment further includes: continuously acquiring the cold water temperature of the cold water tank when the refrigeration device is in the heat preservation operation mode; and controlling the refrigeration device and the circulation pump to operate when the cold water temperature is greater than a third preset temperature, until the cold water temperature is less than or equal to a second preset temperature, wherein the third preset temperature is greater than or equal to the second preset temperature.

[0040] Specifically, when the chilled water device is in heat preservation mode, the refrigeration unit and circulating pump can be started and controlled according to the chilled water temperature in the chilled water tank. Specifically, when the chilled water temperature exceeds the third preset temperature, it indicates that the chilled water in the tank has cooled due to heat dissipation from prolonged stagnation, thus the circulating pump and refrigeration unit can be controlled to operate. The circulating pump pumps the chilled water from the tank to the ice maker, where an evaporator cools the water. After cooling by the evaporator, the water flows back to the chilled water tank through a guide channel on the ice maker, maintaining the chilled water temperature in the tank below or equal to the second preset temperature. Optionally, the third preset temperature in this embodiment can be 7 degrees Celsius, 7.5 degrees Celsius, 8 degrees Celsius, etc. It should be noted that when the chilled water temperature in the tank returns to or falls below the second preset temperature, the refrigeration unit and circulating pump can be controlled to stop operating.

[0041] In some embodiments of the present invention, the control method for the drinking water equipment further includes: when the drinking water equipment starts the cooling water operation, controlling the compressor to start operation after a third preset time delay.

[0042] Specifically, when the water dispenser is in cooling mode, the compressor needs to be delayed for a third preset time before starting. This is to prevent pressure imbalance on the high and low pressure sides after the compressor is shut down. If it starts immediately, the compressor will face huge starting resistance, which may damage the motor or circuit. Therefore, to improve the compressor's service life, this embodiment also sets a third preset time as the compressor's delayed start-up time to ensure pressure balance on the high and low pressure sides when the compressor starts. Optionally, the third preset time in this embodiment can be 3 minutes.

[0043] In summary, the control method for the drinking water equipment in this embodiment of the invention can ensure the smooth operation of the cooling water condition, improve the user's water experience, and at the same time ensure that the function of the drinking water equipment is not affected, thereby extending the service life of the drinking water equipment.

[0044] Furthermore, the present invention proposes a computer-readable storage medium storing a control program for a drinking water device. When the control program for the drinking water device is executed by a processor, it implements the control method for the drinking water device according to any of the above embodiments.

[0045] The computer-readable storage medium of this invention executes the control method of the water drinking device stored thereon through a processor, which can ensure the smooth operation of the cooling water condition, improve the user's water use experience, and at the same time ensure that the function of the water drinking device is not affected and extend the service life of the water drinking device.

[0049] In some embodiments of the present invention, the control module 602 is further configured to: control the refrigerant solenoid valve to open every first preset time interval when the ambient temperature is greater than or equal to a first preset temperature, and control the refrigerant solenoid valve to close after the ice attached to the evaporator is removed; control the refrigerant solenoid valve to open every second preset time interval when the ambient temperature is less than the first preset temperature, and control the refrigerant solenoid valve to close after the ice attached to the evaporator is removed, wherein the first preset time interval is longer than the second preset time interval.
