[0033] 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.

[0034] The drinking water equipment and its control method and device, and storage medium according to the embodiments of the present invention are described below with reference to the accompanying drawings.

[0035] The drinking water equipment in the present invention can have the functions of purification, heating, cooling, ice making and the like, and requires the coordinated use of a booster pump and a variable frequency compressor, wherein the booster pump can pressurize the external water supply so that the water supply of the drinking water equipment is filtered through a water filtering device, while the variable frequency compressor can complete the functions of cooling and ice making and the like.

[0036] Figure 1 It is a flow chart of a control method of a drinking water device in one embodiment of the present invention.

[0037] like Figure 1 As shown, the present invention proposes a control method for a drinking water device, the method comprising the following steps:

[0038] S10, when the water level in the pure water tank is lower than the preset water level, the variable frequency booster pump is controlled to be in operation, so that the water inlet of the drinking water equipment is filtered by the water filtering device and then flows into the pure water tank.

[0039] Specifically, the pure water tank in this embodiment is used to store pure water filtered by the filter device. This pure water can be drunk directly and is also used for refrigeration and ice making of drinking water equipment. When the water level in the pure water tank is lower than the preset water level, it means that the amount of water in the pure water tank is less and needs to be replenished. Then, the variable frequency booster pump can be controlled to be in operation, so that the external water supply pump can be sent to the water filter device for filtering through the variable frequency booster pump. After that, the pure water after filtering flows into the pure water tank to be stored in the pure water tank for use. It should be noted that after the water level of the pure water in the pure water tank reaches the full water level, the variable frequency booster pump can be controlled to stop running.

[0040] S20, when the drinking water device performs an ice-making operation, the variable frequency compressor is controlled to be in an operating state, wherein the variable frequency booster pump and the variable frequency compressor are operated in a time-sharing manner.

[0041] Specifically, in this embodiment, the pure water in the pure water tank can be refrigerated or iced by a variable frequency compressor, so when the drinking water equipment performs the ice-making operation, the variable frequency compressor is controlled to be in operation. Among them, the variable frequency compressor and the variable frequency booster pump are controlled by a variable frequency chip, and the two variable frequency circuits are combined into one circuit, which can reduce the use of electronic components, reduce the circuit load, and reduce the circuit design cost. In this embodiment, the variable frequency booster pump and the variable frequency compressor are controlled in time by a variable frequency chip, that is, the variable frequency booster pump and the variable frequency compressor cannot run at the same time. When one is in operation, the other must be in shutdown. For example, when the drinking water equipment is taking in water, it cannot realize the refrigeration function, or when it is refrigerating, it cannot take in water. Obviously, these two will not reduce the user experience, but can fully reduce the manufacturing cost and circuit complexity of the drinking water equipment to improve the product's competitive ability.

[0042] In some embodiments of the present invention, Figure 2 As shown, the water filtering device includes a first filter element 11 and a second filter element 12, the first filter element 11 includes a first water inlet, a first water outlet, a second water inlet and a second water outlet, the second filter element 12 includes a water inlet and a water outlet, the drinking water equipment also includes a main water inlet valve and a pure water tank 21 water inlet valve, the water outlet of the main water inlet valve is connected to the first water inlet of the first filter element 11, the water inlet of the variable frequency booster pump M is connected to the second water outlet of the first filter element 11, the water outlet of the variable frequency booster pump M is connected to the water inlet of the second filter element 12, the water outlet of the second filter element 12 is connected to the second water inlet of the first filter element 11, the first water outlet of the first filter element 11 is connected to the water inlet of the pure water tank 21 water inlet valve, and the water outlet of the pure water tank 21 water inlet valve is connected to the pure water tank 21.

[0043] Specifically, the water filter device of this embodiment includes a first filter element 11 and a second filter element 12, wherein the first filter element 11 may include a pre-filter element and a post-filter element, and the second filter element 12 may be a RO (Reverse Osmosis) filter element, wherein the external water supply may enter the first filter element 11 through the main water inlet valve, wherein, if it is tap water, it may be directly supplied to the tap after passing through the first filter element 11, wherein the tap water is generally kitchen water, toilet water, etc., and at this time, it may not be filtered through the second filter element 12. If water is supplied to the pure water tank 21, the water filtered by the first filter element 11 may also be filtered through the second filter element 12 through the second water outlet, the second water inlet and the control of the variable frequency booster pump M, and then flow to the first filter element 11 after the filtration is completed, so as to flow to the pure water tank 21 through the first water outlet of the first filter element 11 and the water inlet valve of the pure water tank 21. A branch is provided in the filtration water circuit of the second filter element 12, and a reflux valve and a one-way valve are provided on the branch to reduce the water pressure of the circulating water circuit to ensure that the second filter element 12 can fully filter the water flow. A one-way valve and a water pressure switch are also provided in the water circuit between the first filter element 11 and the pure water tank 21 to prevent the backflow of water from affecting the operation of the first filter element 11.

[0044] In this embodiment, when the variable frequency booster pump M is in operation, the main water inlet valve and the pure water tank water inlet valve are controlled to be in an open state.

[0045] Specifically, in order to ensure successful water inflow into the pure water tank 21, when the variable frequency booster pump M starts to run, the present embodiment controls the main water inlet valve and the pure water tank water inlet valve to be in an open state, so that the pure water filtered by the first filter element 11 and the second filter element 12 can flow smoothly into the pure water tank 21.

[0046] In some embodiments of the present invention, the drinking water device further includes an ice making box, an ice making limit switch and an ice stripping limit switch. When the drinking water device performs an ice making operation, the drinking water device can specifically complete ice making in the ice making box through an evaporator, and then use a motor to control the ice making box to flip so as to pour out the ice water, and then export the remaining ice cubes into the ice storage box, and then use an export device to export the ice cubes according to the needs of the user. During the application of the drinking water device, it is very important that the ice making box can be flipped into place. If the ice making box fails to flip to the ice making position and starts to make ice, then the drinking water device cannot normally realize the ice making function. Obviously, the ice making box will correspond to different positions in different working states. The present invention uses an ice making limit switch and an ice stripping limit switch to limit the ice making box to determine that the ice making box is in a normal position, reduce the failure rate of the ice making operation, control the drinking water device to successfully complete the ice making operation, and improve product safety and user experience.

[0047] Figure 3 It is a flow chart of a control method for drinking water equipment in another embodiment of the present invention.

[0048] like Figure 3 As shown, the control method of the drinking water equipment in this embodiment includes the following steps:

[0049] S301, when the drinking water device performs an ice-making operation, obtaining status information of the ice-making operation.

[0050] S302: driving the ice-making box according to the status information.

[0051] Specifically, the control method of the drinking water device in this embodiment is applied to the ice-making operation of the drinking water device. Since the ice cubes of the drinking water device are easily stuck, the ice-making box cannot be turned over in place. The control method of this embodiment can solve this problem, so that the drinking water device can effectively complete the ice-making and ice-discharging procedures and automatically eliminate the fault. For different status information in the ice-making operation, the ice-making box is in different positions. In this embodiment, the ice-making box can be driven by a stepper motor to ensure that the drinking water device successfully completes the ice-making operation.

[0052] S303, obtaining the switch status of the ice making limit switch and the switch status of the ice defrosting limit switch.

[0053] Specifically, after the ice-making box is driven, it can be further determined whether the ice-making box is flipped into place. Specifically, it can be determined by the states of the ice-making limit switch and the ice-defrosting limit switch. First, the switch states of the ice-making limit switch and the ice-defrosting limit switch are obtained by the sensor, wherein the switch states include an open state and a closed state. When the ice-making box is in the ice-making position, the ice-making limit switch is closed and the ice-defrosting limit switch is disconnected. When the ice-making box is in the ice-defrosting position, the ice-defrosting limit switch is closed and the ice-making limit switch is disconnected.

[0054] S304: adjusting the ice making box and the status information according to the switch state of the ice making limit switch and the switch state of the ice removing limit switch to reduce the failure rate of the ice making operation.

[0055] Specifically, the ice-making operation includes multiple ice-making states. After the ice-making box is driven by a stepper motor, the switch states of the two limit switches, the ice-making limit switch and the ice-removing limit switch, can be used to determine whether the ice-making box is successfully flipped to the specified position, and then the subsequent ice-making box and ice-making states can be adjusted, so that the drinking water equipment can be ready to successfully complete the ice-making operation and reduce the failure rate of the ice-making operation.

[0056] In this embodiment, the ice-making operation includes multiple state information, and the specific state information may include power-on standby state, power-on deicing state, standby state, variable frequency compressor forced protection state, ice-making state, ice-making pause state, deicing state, return fault deicing state, return fault standby state, dump fault deicing state and dump fault standby state. The following embodiments will describe in detail the specific operations of the drinking water device in different ice-making states.

[0057] The present invention starts with the drinking water device being powered on to perform the ice-making operation. After the drinking water device is powered on, it will be in a power-on standby state. In the power-on standby state, Figure 4 As shown, the control method includes:

[0058] S401, obtaining the duration of the power-on standby state.

[0059] S402: When the duration is greater than or equal to the first preset duration, the state information is adjusted to a power-on deicing state.

[0060] Specifically, after the drinking water device is in the power-on standby state, the timing starts, and the standby time of the drinking water device in the power-on standby state is continuously obtained. If the standby time reaches the first preset time, after the detection of various functions in the drinking water device is completed, the drinking water device can be controlled to enter the upper ice-defrosting state. The ice cubes remaining in the ice-making box after the last ice-making operation of the drinking water device can be cleaned up through the power-on ice-defrosting state to avoid affecting the current ice-making operation. Optionally, the first preset time of this embodiment can be two minutes, three minutes or four minutes, etc., and the first preset time can be set according to the specification parameters of the drinking water device, which is not specifically limited here.

[0061] It should be noted that when the drinking water equipment is in the power-on standby state, the load used for ice making can be set to a non-working state. For example, the variable frequency compressor, circulating water pump, refrigerant solenoid valve, etc. can all be set to a non-working state. Among them, the circulating water pump can pump the cold water tank storing cold water in the drinking water equipment into the ice box, and through the operation of the variable frequency compressor, refrigerant solenoid valve and other equipment, the water in the ice box is processed to make ice.

[0062] After the drinking water equipment is powered on and defrosting, Figure 5 As shown, the control method includes:

[0063] S501, obtaining temperature information of the environment in which the ice box is located, and determining the defrosting time according to the temperature information.

[0064] S502, after the ice-making box is turned back and forth from the ice-making position to the ice-defrosting position for a first preset number of times by controlling the stepper motor, the state information is adjusted to the standby state, wherein the duration of stay at the ice-making position or the ice-defrosting position each time is the defrosting duration.

[0065] Specifically, after the drinking water equipment enters the power-on deicing state, the ice cubes remaining in the ice box can be shoveled and sent to the ice storage box by flipping the ice box, so that the current ice making operation can be completed smoothly and the failure rate can be reduced. More specifically, the variable frequency compressor and the refrigerant solenoid valve can be controlled to open first, and the ice cubes attached to the evaporator can be deiced. It can be understood that the evaporator is arranged above the ice box, and the ice cubes removed from the evaporator can accurately fall into the ice box. After the evaporator is deiced, the stepper motor can control the ice box to flip to the deicing position for five seconds. If the deicing limit switch is closed, it means that the ice box has been flipped to the deicing position, and then the stepper motor can be controlled to stop. Then the stepper motor controls the ice box to flip to the ice making position for five seconds. If the ice making limit switch is closed, it means that the ice box has been flipped to the ice making position, and then the stepper motor is controlled to stop. The ice box is counted once when it flips back and forth. After repeating the above steps for the first preset number of times, the ice box is controlled to flip and stop at the ice making position. Then, it is detected that the ice making limit switch is in a closed state and the ice removing limit switch is in an open state, which means that the ice box has completed the power-on ice removing and the ice box has been flipped in place, and the drinking water device can be controlled to enter the standby state. It should be noted that the ice box will stay when it flips to the ice making position or the ice removing position, and the length of the stay can be determined according to the temperature of the environment in which the ice box is currently located, wherein the lower the temperature of the environment, the longer the stay time.

[0066] Optionally, the first preset number of times may be two times, or more times, with the purpose of ensuring that the ice cubes remaining in the drinking water device can be completely shoveled away.

[0067] In some embodiments of the present invention, the drinking water device includes a cold water tank, a refrigeration switch and an ice-making switch. The water stored in the cold water tank can be used for refrigeration or ice-making. When the drinking water device is in a standby state, Figure 6 As shown, the control method also includes:

[0068] S601, obtaining the water storage capacity of the cold water tank, the temperature of the cold water in the cold water tank, the switch status of the refrigeration switch, and the switch status of the ice-making switch.

[0069] S602, controlling the stepper motor according to the water storage amount, the temperature of the cold water, the on / off state of the refrigeration switch, and the on / off state of the ice-making switch.

[0070] S603, after the stepper motor has executed the different procedures of controlling the drinking water equipment to be in a standby state.

[0071] Specifically, the cold water tank of this embodiment can refer to the relevant description of the above embodiment. The cold water tank is specifically used to store cold water. The cold water can be directly provided to the user or pumped to the ice box through a circulating water pump for ice making. In addition, the drinking water device in this embodiment also includes a refrigeration switch and an ice making switch. After the drinking water device is powered on, refrigeration can be performed first, and then ice making can be performed. It should be noted that ice cubes may also be generated during the refrigeration process.

[0072] When the drinking water device is in a standby state, different programs in the standby state can be further judged. In the standby state, the drinking water device needs to be refrigerated first to meet the subsequent ice-making state requirements. Specifically, the stepper motor can be controlled according to the temperature of the cold water, the water storage volume, the refrigeration switch and the ice-making switch, so that the stepper motor can control the ice-making box, and then the drinking water device is controlled to enter different programs in the standby state according to the switch states of the ice-making limit switch and the ice-defrosting limit switch. In this embodiment, the standby state includes multiple programs, which can specifically include a refrigeration shutdown program, a refrigeration and heat preservation program, a refrigeration program, a refrigeration and ice-defrosting program, and a refrigeration and ice-defrosting waiting program.

[0073] In this embodiment, when the drinking water device is in a standby state, the water storage amount in the cold water tank can be determined first, such as Figure 7 As shown, the control method also includes:

[0074] S701, if it is determined that the cold water tank is in a water shortage state according to the water storage capacity, the drinking water device is controlled to enter a refrigeration shutdown program, and the ice box is flipped to the ice-removing position through a stepper motor.

[0075] S702: If it is determined based on the water storage capacity that the cold water tank is not short of water, the drinking water equipment is directly controlled to enter the refrigeration shutdown procedure.

[0076] Specifically, since the variable frequency booster pump and the variable frequency compressor cannot run at the same time, it is necessary to ensure that the cold water tank will not be short of water when the variable frequency compressor makes ice. Because the water used by the drinking water equipment for making ice is provided by the cold water tank, when the cold water tank is short of water, no refrigeration is performed, and the drinking water equipment is controlled to enter the refrigeration shutdown program, and the ice box is turned to the de-icing position by the stepper motor. It is understandable that turning the ice box to the de-icing position is equivalent to not placing the ice box directly below the evaporator. At this time, the circulating water pump cannot normally pump cold water to the ice box, and the water in the cold water box will flow back to the cold water tank after being pumped to the ice box. It should be noted that only the water flow direction between the cold water tank, the ice box, and the circulating water pump is described here, and the specific setting position of the embodiment may not be specifically limited. If the cold water tank is not short of water, then the refrigeration shutdown program can be directly entered without turning the ice box to the de-icing position, so that the ice making operation can be successfully completed when executing the subsequent steps.

[0077] During the refrigeration shutdown procedure, if Figure 8 As shown, the control method also includes:

[0078] S801, when the refrigeration switch is closed, the ice-making switch is opened, and the temperature of the cold water is higher than the refrigeration start temperature, the ice-making box is controlled by the stepper motor to flip to the ice-making position, and the drinking water equipment is controlled to enter the refrigeration program.

[0079] S802, when the refrigeration switch is closed, the ice-making switch is disconnected and the temperature of the cold water is lower than or equal to the refrigeration start temperature, the stepper motor is used to control the ice-making box to flip to the ice-removing position, and the drinking water equipment is controlled to enter the refrigeration and heat preservation program.

[0080] S803, when the refrigeration switch is turned off, the ice-making switch is turned on, and the temperature of the cold water is higher than the ice-cold start temperature, the ice-making box is turned to the ice-making position through the stepper motor, and the drinking water equipment is controlled to enter the refrigeration program.

[0081] S804, when the refrigeration switch is disconnected, the ice-making switch is closed and the temperature of the cold water is lower than or equal to the cold start temperature, the ice-making box is controlled by the stepper motor to flip to the ice-removing position, and the drinking water equipment is controlled to enter the refrigeration and heat preservation program.

[0082] S805, when the refrigeration switch is turned off and the ice-making switch is turned off, the ice-making box is turned to the ice-removing position by controlling the stepper motor.

[0083] Specifically, after the drinking water equipment enters the refrigeration shutdown program, the refrigeration switch and the ice-making switch are judged, and combined with the temperature of the cold water in the cold water tank, in this embodiment, the switch states of the refrigeration switch and the ice-making switch have three states, namely, the refrigeration switch is closed and the ice-making switch is disconnected, the refrigeration switch is disconnected and the ice-making switch is closed, and both the refrigeration switch and the ice-making switch are disconnected.

[0084] If the refrigeration switch is in the closed state and the ice-making switch is disconnected, and the temperature of the cold water in the cold water tank is higher than the refrigeration start temperature, the ice-making box can be controlled by the stepper motor to flip to the ice-making position. If the ice-making limit switch is closed, the stepper motor will not work. If the temperature of the cold water is lower than or equal to the refrigeration start temperature at this time, the ice-making box will be controlled by the stepper motor to flip to the ice-removing position, and the drinking water equipment will be controlled to enter the refrigeration and heat preservation program. If the ice-making limit switch is disconnected, the stepper motor will not work.

[0085] If the refrigeration switch is in the off state and the ice-making switch is closed, and the temperature of the cold water in the cold water phase is higher than the ice-cold starting temperature, the ice-making box can be controlled by the stepper motor to flip to the ice-making position. If the ice-making limit switch is closed, the drinking water equipment is controlled to enter the refrigeration program, and the stepper motor does not operate. If the temperature of the cold water is lower than or equal to the ice-cold starting temperature at this time, the ice-making box is controlled by the stepper motor to flip to the ice-defrosting position. If the ice-defrosting limit switch is closed, the drinking water equipment is controlled to enter the ice-making and insulation program, and the stepper motor does not operate.

[0086] If the refrigeration switch is in the off state and the ice-making switch is also in the off state, the ice-making box is turned to the de-icing position by the stepper motor, and after the de-icing limit switch is closed, the stepper motor stops rotating and does not move.

[0087] Optionally, in this embodiment, the refrigeration start-up temperature may be 9.5 degrees Celsius and the ice-cold start-up temperature may be 8.5 degrees Celsius.

[0088] In some embodiments of the present invention, during the refrigeration process, such as Fig. 9 As shown, the control method also includes:

[0089] S901, when the ice making limit switch is in the off state and the time when the drinking water device enters the refrigeration program exceeds the second preset time, the ice making box is flipped to the ice making position by the stepper motor.

[0090] S902: When the ice making limit switch is in a closed state, the ice removing limit switch is in an open state, and the time when the drinking water device enters the refrigeration program does not exceed a second preset time, water is poured into the ice making box.

[0091] Specifically, in the refrigeration program, the ice-making limit switch is first judged, and the time when the drinking water device enters the refrigeration program is counted. When the ice-making limit switch is disconnected and the drinking water device enters the refrigeration program for a time period exceeding the second preset time period, it means that the ice box is not in the ice-making position, and the stepper motor can be used to control the ice box to flip to the ice-making position. If the ice-making limit switch is in a closed state, the ice-removing limit switch is in an open state, and the drinking water device has not entered the refrigeration program for a time period exceeding the second preset time period, it means that the ice box is in the ice-making position, so water can be added to the ice box, that is, the variable frequency compressor and the circulating water pump are turned on.

[0092] Optionally, in this embodiment, the second preset duration may be 5 minutes.

[0093] Furthermore, in the refrigeration process, the control method further includes:

[0094] When the refrigeration switch is closed and the ice-making switch is disconnected and the temperature of the cold water is lower than the refrigeration and insulation temperature, or the refrigeration switch is disconnected and the ice-making switch is closed and the temperature of the cold water is lower than the icing and insulation temperature, or the refrigeration switch is disconnected and the ice-making switch is disconnected, if the ice box is not full of ice, the drinking water equipment is controlled to enter the refrigeration and defrosting program, and the ice box is flipped to the defrosting position through the stepper motor; if the ice box is full of ice, the drinking water equipment is controlled to enter the forced protection state of the variable frequency compressor, and the ice box is flipped to the defrosting position through the stepper motor, and after the third preset time, the drinking water equipment is controlled to enter the refrigeration and defrosting waiting program.

[0095] Specifically, among the three conditions described above, namely, the refrigeration switch is closed, the ice-making switch is disconnected, and the temperature of the cold water is lower than the refrigeration and heat preservation temperature, the refrigeration switch is disconnected, the ice-making switch is closed, and the temperature of the cold water is lower than the ice-cooling and heat preservation temperature, and the refrigeration switch is disconnected and the ice-making switch is disconnected, if any of the three conditions is met, the next step of judgment can be performed, specifically judging whether the ice box is full of ice. It should be noted that de-icing when the ice box is not full of ice can improve the success rate of de-icing, while if the ice box is full of ice, the success rate of de-icing is low, and ice cubes may stick together, and the ice box cannot be de-iced well. Therefore, this embodiment stipulates that if the ice box is full of ice, the drinking water equipment is controlled to enter the forced protection state of the variable frequency compressor, and the ice box is controlled to flip to the ice-defrosting position through the stepper motor until the ice-defrosting limit switch is in the closed state, then the stepper motor is controlled to stop rotating, and after a third preset time, the drinking water equipment is controlled to enter the refrigeration defrosting waiting program; and if the ice box is full of ice, the drinking water equipment is controlled to enter the refrigeration defrosting program, and the ice box is flipped to the ice-defrosting position through the stepper motor, and after the ice-defrosting limit switch is closed, the stepper motor is controlled to stop rotating.

[0096] Optionally, in this embodiment, the refrigeration insulation temperature is 6 degrees Celsius, the ice insulation temperature is 7 degrees Celsius, and the third preset time length is 3 minutes.

[0097] In some embodiments of the present invention, after the drinking water device enters the refrigeration and defrosting process, Fig.10 As shown, the control method includes:

[0098] S1001, controlling the ice-making box to flip back and forth from the ice-making position to the ice-removing position by a stepper motor for a second preset number of times and then being in the ice-making position, and detecting the states of the ice-making switch and the ice-making box.

[0099] S1002, when the ice-making switch is turned off and the ice box is not full of ice, the drinking water device is controlled to enter the ice-making state. If the ice-making limit switch is in the closed state and the ice-defrosting limit switch is in the open state, water is injected into the ice-making box; if the ice-making limit switch is in the open state and the ice-defrosting limit switch is in the closed state, the ice-making box is flipped to the ice-defrosting position by the stepper motor.

[0100] S1003, when the ice-making switch is turned off or the ice-making box is full of ice, the ice-making box is turned over to the ice-removing position by the stepper motor.

[0101] Specifically, after the drinking water device enters the refrigeration and deicing program, the refrigerant valve can be controlled to open for deicing operation, wherein the variable frequency compressor is always in the open state to reduce the number of starts and stops of the variable frequency compressor, thereby increasing the service life of the variable frequency compressor, and then the ice box is controlled by the stepper motor to flip to the ice making position for five seconds. During the flipping process, the variable frequency compressor and the refrigerant solenoid valve are continuously opened. After the ice making limit switch is closed, the ice box is flipped to the deicing position for another five seconds. After the deicing limit switch is closed, the stepper motor can repeat the above steps for a second preset number of times, and finally the ice box needs to be flipped to the ice making position. Optionally, the second preset number of times can be twice.

[0102] After the ice box is turned over, the switch state of the ice-making switch and the state of the ice box are detected. If the ice-making switch is in the closed state and the ice box is not full of ice, the drinking water device is controlled to enter the ice-making state, and then the following judgment is made: if the ice-making limit switch is closed and the ice-removing limit switch is disconnected, water is poured into the ice box, otherwise the ice box is controlled by the stepper motor to tilt to the ice-removing position until the ice-removing limit switch is closed, and then the stepper motor is controlled to stop rotating. If the ice-making switch is disconnected or the ice box is full of ice, the ice box is controlled by the stepper motor to turn to the ice-removing position until the ice-removing limit switch is closed, and then the stepper motor is controlled to stop rotating.

[0103] In some embodiments of the present invention, after the drinking water device enters the cooling and heat preservation program, the control method includes:

[0104] When the ice-making switch is disconnected, or the ice-making switch is closed and the ice box is full of ice, if the refrigeration switch is closed and the temperature of the cold water is higher than the refrigeration start temperature, then when the ice-making limit switch is in the disconnected state, the ice-making box is controlled to flip to the ice-making position through the stepper motor, and the drinking water equipment is controlled to enter the refrigeration program; when the ice-making limit switch is not in the disconnected state, the drinking water equipment is directly controlled to enter the refrigeration program; if the refrigeration switch is disconnected, the drinking water equipment is controlled to enter the refrigeration shutdown program, and the ice-making box is controlled to flip to the ice-removing position through the stepper motor.

[0105] Specifically, after the drinking water device enters the refrigeration and heat preservation program, the corresponding operation can be performed by judging whether the ice-making switch, the refrigeration switch and the ice-making box are full of ice. When the ice-making switch is disconnected, or the ice-making switch is closed and the ice-making box is full of ice, it is judged whether the refrigeration switch is closed. If the refrigeration switch is closed, the temperature of the cold water is further judged. If the temperature of the cold water is also higher than the refrigeration start temperature, when the ice-making limit switch is disconnected, the ice-making box is turned to the ice-making position by the stepper motor, and when the ice-making limit switch is closed, the stepper motor is controlled to stop rotating to enter the refrigeration program. If the ice-making limit switch is not in the disconnected state, the drinking water device can be directly controlled to enter the refrigeration program, and then the stepper motor stops rotating. If it is judged that the refrigeration switch is disconnected, the drinking water device can be controlled to enter the refrigeration shutdown program, and the ice-making box is controlled to flip to the ice-removing position by the stepper motor until the ice-removing limit switch is in the closed state, and then the stepper motor is controlled to stop rotating. It should be noted that the refrigeration shutdown program can be specifically referred to the relevant description of the above embodiment, and will not be repeated here.

[0106] Optionally, in this embodiment, the refrigeration start temperature is 9.5 degrees Celsius.

[0107] In some embodiments of the present invention, during the refrigeration defrosting waiting procedure, Fig.11 The control method further comprises:

[0108] S1101, when the ice box is not full of ice, control the drinking water device to enter a refrigeration and ice-defrosting program, and control the ice box to flip to the ice-defrosting position through a stepper motor and continue for a fourth preset time period.

[0109] S1102, when the ice box is full of ice, if the refrigeration switch is closed and the temperature of the cold water is higher than the refrigeration start temperature, or the refrigeration switch is disconnected and the ice switch is closed and the temperature of the cold water is higher than the ice start temperature, the ice limit switch is detected.

[0110] S1103, when the ice making limit switch is in the off state, the ice making box is turned to the ice making position by controlling the stepper motor.

[0111] S1104, when the ice making limit switch is not in the disconnected state, the drinking water device is controlled to enter the refrigeration and heat preservation program, and the ice making box is controlled by the stepper motor to flip to the ice removing position.

[0112] Specifically, after the drinking water device enters the refrigeration and de-icing waiting program, the following operations can be performed by detecting the states of the ice box and the ice making limit switch. First, when the ice box is not full of ice, the drinking water device is controlled to enter the refrigeration and de-icing state, and then the ice box is controlled by the stepper motor to flip to the de-icing position and last for a fourth preset time. After the de-icing limit switch is closed, the stepper motor can be controlled to stop rotating. If the ice box is full of ice, it can be determined whether one of the two conditions, that is, the refrigeration switch is closed and the temperature of the cold water is greater than the refrigeration start temperature, and the refrigeration switch is disconnected and the ice making switch is closed and the temperature of the cold water is greater than the ice cold start temperature, is met. If one of the two conditions is met, the drinking water device is controlled to enter the refrigeration program. At the same time, if it is determined that the ice making limit switch is disconnected, the ice box is controlled by the stepper motor to flip to the ice making position until the ice making limit switch is closed, and the motor is controlled to stop rotating. If the ice making limit switch is not in the disconnected state, the drinking water device is controlled to enter the refrigeration and heat preservation program, and the ice box is controlled by the stepper motor to flip to the de-icing position.

[0113] Optionally, in this embodiment, the refrigeration start temperature is 9.5 degrees Celsius, the cold start temperature is 8.5 degrees Celsius, and the fourth preset time length is 5 seconds.

[0114] In some embodiments of the present invention, when the drinking water equipment is in the variable frequency compressor forced protection state, the method further includes: controlling the load of the drinking water equipment to stop working, and controlling the drinking water equipment to enter a standby state after a fifth preset time.

[0115] Specifically, the forced protection state of the variable frequency compressor is the state that needs to be entered when the ice box is full of ice in the refrigeration program. After the drinking water equipment enters the forced protection state of the variable frequency compressor, the load of the drinking water equipment can be controlled to stop working, for example, the variable frequency compressor, the circulating water pump, and the refrigerant solenoid valve all do not work, and then the drinking water equipment is in this state for a fifth preset time period, and then the drinking water equipment is controlled to enter the standby state. The specific description of the standby state can be referred to the description of the above embodiment, and will not be repeated here.

[0116] Optionally, the fifth preset duration in this embodiment may be 3 minutes.

[0117] In some embodiments of the present invention, the ice-making state of the drinking water device includes an ice box dumping program, an ice box returning program, an ice box water replenishing program and an ice making program.

[0118] Specifically, before the drinking water device guides the made ice to the ice storage box during the ice-making process, it is necessary to control the ice box to tilt so as to pour out the water in the ice box, and then guide the ice cubes into the ice storage box while controlling the ice box to return to its original position, and then replenish water in the ice box, and continue the ice-making procedure after replenishing water. The specific operations of different procedures of the drinking water device in the ice-making state are described below.

[0119] In some embodiments of the present invention, when the drinking water equipment is in the ice box dumping program, the control method also includes: when controlling the ice box to flip to the ice-defrosting position through a stepper motor, if the stepper motor flips into place and the ice-defrosting limit switch is in the disconnected state, the number of abnormal dumping times of the ice box is controlled to increase by one, otherwise the number of abnormal dumping times is cleared to zero; if the stepper motor flips into place, the drinking water equipment is controlled to enter the ice box return program.

[0120] Specifically, in the ice box dumping procedure, the ice box is first turned to the ice-removing position by controlling the stepper motor. In the process of controlling the ice box to turn by the stepper motor, the stepper motor can be controlled according to the preset step. Under normal circumstances, after the motor turns to the right position, the corresponding limit switch will also be in a closed state, or the turning time is set, and after the default stepper motor runs normally for the turning time, it means that the ice box has turned to the right position. For example, after the stepper motor is controlled to turn to the ice making position, the ice making limit switch will be in a closed state, and if the ice making limit switch is not closed, it means that there is an abnormality.

[0121] In this embodiment, the ice box flipping from the ice making position to the ice removing position can be defined as tipping, and the ice box flipping from the ice removing position to the ice making position can be defined as returning. In the process of the stepper motor controlling the ice box to flip from the ice making position to the ice removing position, if the stepper motor has completed the flipping according to the instruction, but the ice removing limit switch is still in the disconnected state at this time, it means that the ice box has not been flipped to the ice removing position, but the stepper motor has completed the control, so there is a tipping abnormality, and the number of tipping abnormalities of the ice box can be controlled to increase by one. If the stepper motor flips to the right position and the ice removing limit switch is also in the closed state, it means that the ice box can complete the tipping normally, so the number of tipping abnormalities can be cleared, and the drinking water device can be controlled to enter the ice box return program.

[0122] During the ice tray return procedure, Fig.12 As shown, the control method also includes the following steps:

[0123] S1201, when the ice making limit switch is in a closed state, the ice removing limit switch is in an open state, and the number of abnormal dumping is zero, the drinking water device is controlled to enter the ice box water replenishment program.

[0124] S1202, when the ice making limit switch is not in the closed state, or the ice removing limit switch is not in the open state, or the number of abnormal tipping is non-zero, the ice making box is flipped to the ice removing position by controlling the stepper motor.

[0125] S1203, when the stepper motor is turned over to the position and the ice-removing limit switch is in the disconnected state, the abnormal return count of the ice box is performed.

[0126] S1204, when the number of abnormal dumping and the number of abnormal ice box return are both less than the third preset number, the drinking water equipment is controlled to enter the ice box dumping program; when the number of abnormal dumping or the number of abnormal ice box return exceeds the third preset number, the drinking water equipment is controlled to enter the return fault ice-removing state.

[0127] Specifically, after the stepper motor controls the ice box to flip back to its original position, it can be further determined whether the ice making limit switch is in a closed state. If the ice making limit switch is in a closed state and the ice removing limit switch is in an open state, and the number of abnormal tipping is zero, the drinking water device can be further controlled to enter the ice box water replenishment program, and the motor will not operate. If the ice making limit switch is not in a closed state, or the ice removing limit switch is not in an open state, or the number of abnormal tipping is not zero, the ice box can be first controlled by the stepper motor to flip to the ice removing position, and then the stepper motor can be used to control the ice box to return to its original position. The relevant description of the above-mentioned tipping control can be referred to. During the return process, if the stepper motor flips to the original position, but the ice removing limit switch is in an open state, it means that the ice box has not reached the ice removing position, so the ice box will be abnormal during the return process, and then the number of abnormal return of the ice box is controlled to increase by one.

[0128] If the number of dumping abnormalities and the number of returning abnormalities do not exceed the third preset number, the drinking water device can be controlled to enter the ice box dumping program, otherwise the drinking water device can be controlled to enter the return fault de-icing state. In this embodiment, when the ice box has dumping abnormalities and return abnormalities, it may be that there are frozen ice cubes in the flipping circuit of the ice box, which cannot be shoveled during the flipping process of the ice box, so the stepper motor is used to control the ice box to flip back and forth, and the frozen ice cubes in the flipping circuit are shoveled as much as possible. During the flipping process of the ice box, dumping abnormality judgment and return abnormality judgment are still performed on it. When the number of dumping abnormalities exceeds the third preset number, it can be determined that the drinking water device has a fault, and the type of the fault is a dumping fault, that is, it is determined that the drinking water device is in a dumping fault de-icing state, and when the number of returning abnormalities exceeds the third preset number, it can be determined that the drinking water device has a fault, and the type of the fault is a return fault, that is, it is determined that the drinking water device is in a return fault de-icing state.

[0129] Optionally, in this embodiment, the third preset number of times may be set to three. Of course, this embodiment may not impose any specific limitation on its specific value.

[0130] When the drinking water device is in the ice box water filling program, Fig.13 As shown, the control method also includes the following steps:

[0131] S1301: When the ice making limit switch is in a closed state and the ice removing limit switch is in an open state, water is injected into the ice making box, and the water injection time of the ice making box is obtained.

[0132] S1302: When the water injection time reaches a sixth preset time, the drinking water device is controlled to enter an ice making program.

[0133] Specifically, in the process of replenishing water to the ice box, it is necessary to determine whether the ice box is in the ice making position. If the ice box is not in the ice making position, the water replenishment may not be completed normally. For example, if the ice box is in the ice stripping position, the water replenished to the ice box may continue to flow and flow into the cold water tank. Therefore, the present embodiment also specifically judges the ice making limit switch and the ice stripping limit switch. If the ice making limit switch is in a closed state and the ice stripping limit switch is in an open state, it can be indicated that the ice box is in the ice making position, so water can be added to the ice box. In the process of replenishing water to the ice box, the water filling time of the ice box can be obtained. If the water filling time reaches the sixth preset time, it means that the water filling has been completed, so the drinking water device can be controlled to enter the ice making program. It should be noted that the ice box can be set above the cold water tank, so that the value of the sixth preset time length can be increased, because even if the water replenishment time increases and causes cold water to overflow from the ice box, the overflowing water will flow into the cold water tank. Of course, if the ice box is not set above the cold water tank, the value of the sixth preset time length can be smaller.

[0134] After the ice box completes the water replenishment program, the control method includes: when the ice box is full of ice, if the refrigeration switch and the ice-making switch are both closed and the temperature of the cold water is higher than the refrigeration start temperature, or the refrigeration switch is disconnected and the ice-making switch is closed and the temperature of the cold water is higher than the ice-cold start temperature, then the drinking water device is controlled to enter a standby state, otherwise the drinking water device is controlled to enter an ice-making pause state; when the time when the drinking water device is in the ice-making program reaches the target ice-making time, the ice-making box is controlled to flip to the ice-defrosting position through a stepper motor, and then the drinking water device is controlled to enter an ice-defrosting state.

[0135] Specifically, in this embodiment, an ice-making time can be set first. The ice-making time is preset. When the drinking water device enters the ice-making program, the timing starts. When the ice-making time of the drinking water device has not reached the ice-making time, if it is detected that the ice-making box is full of ice, it is determined whether the following conditions are met, and the conditions include the refrigeration switch is closed, the ice-making switch is closed, and the temperature of the cold water is higher than the refrigeration start temperature, and the refrigeration switch is disconnected, the ice-making switch is closed, and the temperature of the cold water is higher than the ice-cold start temperature. When any of the above two conditions is met, the drinking water device is controlled to enter the standby state, specifically the refrigeration program in the standby state; when the above two conditions are not met, the drinking water device is controlled to enter the ice-making pause state, and the ice-making pause state will be described in detail in the following embodiment. When the ice-making time of the drinking water device has reached, the stepper motor is turned to the de-icing position, and the de-icing limit switch is judged. If the de-icing limit switch is in a closed state, the stepper motor is controlled to rotate and enter the de-icing state, and the de-icing state will be described in detail in the following embodiment.

[0136] It should be noted that the variable frequency compressor is in working condition during the whole ice making process of the drinking water equipment. In addition, the refrigeration start temperature can be selected as 9.5 degrees Celsius, and the ice cold start temperature can be selected as 8.5 degrees Celsius.

[0137] When the drinking water device is in the ice-making pause state, the control method also includes the following steps: after the drinking water device enters the ice-making pause state for the seventh preset time period, if the ice box is not full of ice, the ice box is flipped to the ice-removing position by controlling the stepper motor; if the ice box is full of ice, and the refrigeration switch is closed and the temperature of the cold water is higher than the refrigeration start temperature, or the refrigeration switch is disconnected and the temperature of the cold water is higher than the refrigeration start temperature, the drinking water device is controlled to enter the standby state.

[0138] Specifically, after the drinking water device enters the ice-making pause state, it can first wait for the seventh preset time length, which can be three minutes. After three minutes, it is determined whether the ice box is full of ice. If the ice box is not full of ice, the drinking water device can be controlled to enter the de-icing state, specifically by controlling the ice box to flip to the de-icing position through the stepper motor until the de-icing limit switch is closed, and then the stepper motor is controlled to stop rotating. If the ice box is full of ice, it is determined whether one of the following two conditions is met, that is, the refrigeration switch is closed and the temperature of the cold water is higher than the refrigeration start temperature, and the refrigeration switch is disconnected and the temperature of the cold water is higher than the ice-cold start temperature. If one of the above conditions is met, the drinking water device is controlled to enter the standby state. If none of the above conditions are met, the drinking water device is still in the current ice-making pause state.

[0139] Optionally, in this embodiment, the refrigeration start-up temperature may be 9.5 degrees Celsius, and the ice-cold start-up temperature may be 8.5 degrees Celsius.

[0140] In some embodiments of the present invention, when the drinking water device is in a de-icing state, the control method further comprises the following steps:

[0141] When the defrosting load starts and the defrosting time reaches the target defrosting time, if the defrosting limit switch is in the disconnected state, the defrosting fault count is performed, and when the defrosting fault count reaches the fourth preset number of times, it is determined that an ice box defrosting fault has occurred in the drinking water equipment; if the defrosting limit switch is not in the disconnected state, the ice box is first flipped to the ice making position by the stepper motor, and then flipped to the ice defrosting position to enter the normal defrosting waiting return procedure.

[0142] Specifically, the drinking water equipment includes an ice-removing load, which can be a variable frequency compressor and a refrigerant valve load. When the drinking water equipment is defrosting, the defrosting time is first counted. If the defrosting time reaches the target defrosting time, the state of the defrosting limit switch can be determined. If the defrosting limit switch is in the disconnected state, it means that the current ice box is not in the de-icing position, so it is necessary to count the de-icing faults. When the de-icing fault count is less than two times, the stepper motor will continue to flip to the de-icing position, and when the de-icing fault is three times, the drinking water equipment will be controlled to enter the ice box de-icing fault. It should be noted that three times in this example are examples of the fourth preset number of times, and the fourth preset number of times can also be other positive integer values. If the de-icing limit switch is not in the disconnected state, the ice box can be flipped to the ice making position by the stepper motor first, and de-icing is performed once, and then the ice box is flipped to the de-icing position to enter the normal de-icing waiting return program.

[0143] In the normal defrosting waiting return procedure, the control method also includes: when the conditions that the ice-making switch is disconnected, or the ice-making switch is closed and the ice-making box is full of ice and the temperature of the cold water is lower than the ice-cold starting temperature are met, and the conditions that the refrigeration switch is disconnected, or the refrigeration switch is closed and the temperature of the cold water is lower than the refrigeration starting temperature are also met, the drinking water equipment is controlled to enter the variable frequency compressor forced protection state, and the ice-making box is controlled to flip to the defrosting position through the stepper motor; when the conditions that the ice-making switch is disconnected, or the ice-making switch is closed and the ice-making box is full of ice and the temperature of the cold water is lower than the ice-cold starting temperature are not met, or the refrigeration switch is disconnected, or the refrigeration switch is closed and the temperature of the cold water is lower than the refrigeration starting temperature are not met, the drinking water equipment is controlled to enter the standby state.

[0144] Specifically, in the normal defrosting waiting return procedure, if the following conditions are met, the drinking water equipment needs to be controlled to enter the variable frequency compressor forced protection state, the conditions include the ice making switch is disconnected, or the ice making switch is closed and the ice making box is full of ice and the temperature of the cold water is lower than the ice cold start temperature, and the refrigeration switch is disconnected, or the refrigeration switch is closed and the temperature of the cold water is lower than the refrigeration start temperature. If the above conditions are met at the same time, the drinking water equipment enters the variable frequency compressor forced protection state, and controls the ice making box to flip to the defrosting position through the stepper motor, and if the above conditions are not met at the same time, the drinking water equipment can be controlled to enter the standby state.

[0145] It should be noted that, in the forced protection state and standby state of the variable frequency compressor, the specific operation of the drinking water device can refer to the relevant description of the above embodiment, and will not be repeated here to avoid redundancy. Optionally, in this embodiment, the ice-cold start temperature can be 8.5 degrees Celsius, and the refrigeration start temperature can be 9.5 degrees Celsius.

[0146] In some embodiments of the present invention, Fig.14 As shown, when the drinking water equipment is in a dumping fault de-icing state, the method further includes:

[0147] S1401, obtaining the ambient temperature when the drinking water equipment is in a dumping fault de-icing state.

[0148] S1402, controlling the drinking water equipment to defrost.

[0149] S1403, obtaining the defrosting time of the drinking water equipment and the preset defrosting time corresponding to the ambient temperature.

[0150] S1404, when the defrosting time is a preset multiple of the preset defrosting time, the ice-making box is flipped to the defrosting position by controlling the stepper motor, and after the stepper motor is flipped into place, if the ice-making limit switch is in the open state and the defrosting limit switch is in the closed state, it is determined that the drinking water equipment is in the normal defrosting waiting return state, and the ice-making box is flipped to the ice-making position by controlling the stepper motor.

[0151] S1405: If the ice making limit switch is in a closed state or the ice removing limit switch is in an open state, it is determined that the drinking water equipment is in a dumping fault standby state.

[0152] Specifically, in the process of deicing, the drinking water device of the present invention can first control the variable frequency compressor and the refrigerant solenoid valve to open, so that the evaporator that originally made ice can generate heat, and the ice cubes attached to the original evaporator fall into the ice box, and then control the ice box to be dumped to pour out the water in the ice box. In the process of controlling the drinking water device to deicing, the embodiment needs to obtain the ambient temperature and the deicing time of the drinking water device, and then determine the corresponding preset deicing time according to the ambient temperature. The preset deicing time can be pre-stored in the memory and directly queried and obtained according to the ambient temperature.

[0153] After obtaining the preset defrosting time and the actual defrosting time, the two times can be judged. Under normal circumstances, the two times should be equal. If a defrosting failure occurs in the drinking water equipment, when the defrosting time reaches a preset multiple of the preset defrosting time, the ice box can be turned over by the stepper motor, and after the stepper motor is turned over, the switch status of the ice making limit switch and the defrosting limit switch is obtained. Since the stepper motor is controlling the ice box to turn over to the defrosting position at this time, the defrosting limit switch should be in a closed state under normal circumstances, while the ice making limit switch is in an open state. When it is detected that the ice making limit switch and the defrosting limit switch meet the state corresponding to the above normal situation, it is determined that the drinking water equipment is in a normal defrosting waiting return state, and the ice box is turned over to the ice making position by the stepper motor. However, if it is detected that the ice making limit switch and the defrosting limit switch do not meet the state corresponding to the above normal situation, it can be determined that the drinking water equipment cannot perform a normal dumping operation, so the drinking water equipment can be controlled to enter a dumping fault standby state.

[0154] In this embodiment, when the drinking water device is in a dumping fault standby state, the control method further includes:

[0155] The ice box is controlled by a stepper motor to flip to the ice-defrosting position, and after the stepper motor flips into position, if the ice-making limit switch is in a closed state and the ice-defrosting limit switch is in an open state, it is determined that the drinking water equipment is in a dumping fault ice-defrosting state again; if the ice-making limit switch is in an open state or the ice-defrosting limit switch is in a closed state, the ice box is controlled by a stepper motor to flip to the ice-making limit switch in a closed state, and it is determined that the drinking water equipment is in a normal ice-defrosting waiting to return state.

[0156] Specifically, after the drinking water device enters the dumping fault standby state, the ice box can continue to be controlled to flip, and after the stepper motor flips into place, the states of the ice making limit switch and the ice removing limit switch can be further judged to determine whether the ice box has flipped into place. If the ice making limit switch is in a closed state and the ice removing limit switch is in an open state, it means that there is a fault in the flipping of the ice box, so the drinking water device can be controlled to re-enter the dumping fault ice removing state. Of course, if the ice making limit switch is in an open state or the ice removing limit switch is in a closed state, it means that the current ice making limit switch and ice removing limit switch can work normally, and the ice box cannot be flipped normally to the ice making position or the ice removing position is because the flipping path is blocked, so the ice box can be further flipped until the ice making limit switch is in a closed state, that is, the obstacles in the flipping path are removed, and then it is determined that the drinking water device is in a normal ice removing waiting return state.

[0157] In some embodiments of the present invention, Fig.15 As shown, when the drinking water equipment is in a return failure deicing state, the control method further includes the following steps:

[0158] S1501, obtaining the ambient temperature when the drinking water equipment is in a return failure de-icing state.

[0159] S1502, controlling the drinking water equipment to defrost.

[0160] S1503, obtaining the defrosting time of the drinking water equipment and the preset defrosting time corresponding to the ambient temperature.

[0161] S1504, when the defrosting time is a preset multiple of the preset defrosting time, the ice-making box is flipped to the ice-making position by controlling the stepper motor, and after the stepper motor flips to the position, if the ice-making limit switch is in a closed state and the defrosting limit switch is in an open state, it is determined that the drinking water equipment is in a standby state.

[0162] S1505, if the ice making limit switch is in the open state or the ice removing limit switch is in the closed state, the ice making box is flipped to the ice removing position by controlling the stepper motor, and the drinking water equipment is determined to be in the return fault standby state.

[0163] Specifically, in the process of deicing the drinking water device in the present invention, the variable frequency compressor and the refrigerant solenoid valve are also in the open state, so that the evaporator that originally made ice can generate heat, and the ice cubes attached to the original evaporator fall into the ice box, and then the ice box is controlled to be tilted to pour out the water in the ice box, and then the ice box is flipped from the deicing position to the ice making position. In the process of controlling the drinking water device to deicing, this embodiment needs to obtain the ambient temperature and the deicing time of the drinking water device, and then the corresponding preset deicing time can be determined according to the ambient temperature. The preset deicing time can be pre-stored in the memory and directly queried and obtained according to the ambient temperature.

[0164] After obtaining the preset defrosting time and the actual defrosting time, the two times can be judged. Under normal circumstances, the two times should be equal. If a defrosting failure occurs in the drinking water equipment, when the defrosting time reaches a preset multiple of the preset defrosting time, the ice box can be turned over by the stepper motor, and after the stepper motor is turned over, the switch status of the ice making limit switch and the defrosting limit switch is obtained. Since the stepper motor is controlling the ice box to turn over to the ice making position at this time, the ice making limit switch should be in a closed state under normal circumstances, while the defrosting limit switch is in an open state. When it is detected that the ice making limit switch and the defrosting limit switch meet the state corresponding to the above normal situation, the drinking water equipment can be controlled to enter the standby state. However, if it is detected that the ice making limit switch and the defrosting limit switch do not meet the state corresponding to the above normal situation, it can be determined that the drinking water equipment cannot perform a normal return operation, so the ice box can be turned over to the defrosting position, and the drinking water equipment can be controlled to enter the return fault standby state.

[0165] Optionally, the specific value of the preset multiple in the above embodiment may be five times. Of course, in other embodiments, it may also be other values, and the specific value of the preset multiple is not limited here.

[0166] In this embodiment, when the drinking water device is in a return fault standby state, the control method further includes:

[0167] The ice-making box is controlled by a stepper motor to flip to the ice-making position, and after the stepper motor flips into position, if the ice-making limit switch is in a closed state and the ice-defrosting limit switch is in an open state, it is determined that the drinking water equipment is in a standby state; if the ice-making limit switch is in an open state or the ice-defrosting limit switch is in a closed state, the ice-making box is controlled by a stepper motor to flip to the ice-defrosting limit switch in a closed state, and it is determined that the drinking water equipment is in a return fault ice-defrosting state.

[0168] Specifically, after the drinking water device enters the return fault standby state, the ice box can continue to be controlled to flip, and after the stepper motor flips into place, the states of the ice making limit switch and the ice removing limit switch can be further judged to determine whether the ice box has flipped into place. If the ice making limit switch is in a closed state and the ice removing limit switch is in an open state, it means that the ice box can return to its position normally, and then the drinking water device can be controlled to enter the standby state. Of course, if the ice making limit switch is in an open state or the ice removing limit switch is in a closed state, it means that there are still some faults in the current ice box return operation, usually the flipping path of the ice box is blocked, so the ice box can be further flipped until the ice removing limit switch is in a closed state, that is, the obstacles in the flipping path are removed, and then the drinking water device is controlled to re-enter the return fault ice removing state.

[0169] It should be noted that, in the above embodiment, the defrosting time can be determined according to the ambient temperature through the following Table 1, and the speed of the variable frequency compressor can be determined according to the ambient temperature through the following Table 2.
