[0045] The purpose, features and advantages of this application will be further described in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0046] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0047] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0048] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0049] At present, when a water dispenser or water purifier with cooling, heating or ice-making functions is pumping water internally, the water will absorb the odor of the insulation layer and the protective layer. At the same time, the compressor is also dissipating heat when working, which will accelerate the conduction of odor. For example, the internal temperature of the water dispenser can reach above 50°C. In such an environment, the odor volatilized by the insulation layer and the protective layer inside the water dispenser will be absorbed by the water body through the water tank or pipe, eventually causing the water body to have a peculiar smell. In particular, when the cold water in the cold water tank is not used for a long time, the water quality is worse. In the technical solution of the embodiment of the present application, the water in the cold water tank is refluxed, filtered again through the composite filter element, and then flows back into the pure water tank for use in the cold water tank for refrigeration or ice making to ensure the water quality and taste.

[0050] In order to overcome the above technical defects, the embodiment of the present application provides a water dispenser control method applied to a water dispenser, wherein the water dispenser includes a cold water tank, a composite filter element and a pure water tank interconnected by water pipes, forming a cold water return path composed of the cold water tank, the composite filter element and the pure water tank, Figure 1 , Figure 1 This is a flow chart of an embodiment of the water dispenser control method of the present application. The water dispenser control method includes:

[0051] Step S10, when the water dispenser triggers the cold water return instruction, the water in the cold water tank is controlled to flow to the pure water tank after being filtered by the composite filter element;

[0052] The water dispenser in the embodiment of the present application may be a water dispenser or a water purifier with heating, cooling and ice-making functions. The water dispenser control method of the present application may also be applied to a water purifier, which is a new type of drinking water equipment that integrates water purification, drinking, cooling and heating functions. Among them, the cold water tank is used to store cold water so that the refrigeration system and the ice-making system can use the cold water in the cold water tank for cooling and ice-making. In order to prevent the water in the cold water tank from deteriorating due to long-term non-use and affecting the taste of drinking water, in the embodiment of the present application, the water in the cold water tank can be controlled to reflux by triggering a cold water reflux instruction, so that the water in the cold water tank can be filtered through a composite filter element to eliminate the odor in the water and improve the water quality and taste.

[0053] The composite filter element can be the post-filter element of the water dispenser, that is, after the water enters from the outside, it is first filtered by the post-filter element, and then flows to the pure water tank and the cold water tank in sequence. When the water in the cold water tank needs to be filtered, it flows back to the post-filter element for secondary filtration to ensure the water quality and taste of the water body and improve the user's water experience.

[0054] Step S20, controlling the water in the pure water tank to flow to the cold water tank.

[0055] The pure water tank is used to store filtered clean water and supply filtered clean water to the cold water tank, so that the water in the cold water tank remains flowing and clean, and the water quality in the cold water tank is prevented from deteriorating due to long-term use of the water in the cold water tank. It should be noted that the cold water tank, the composite filter element and the pure water tank in the water dispenser of the embodiment of the present application are connected to each other through water pipes, and the flow direction of the water is the composite filter element, the pure water tank, the cold water tank, and the composite filter element in sequence, forming a complete closed reflux path, and the power of the water flow is provided by a water pump arranged on the water pipe to ensure the water circulation inside the water dispenser.

[0056] Furthermore, in a feasible embodiment, before the step of controlling the water in the cold water tank to flow to the pure water tank after being filtered by the composite filter element, the method may further include:

[0057] Step A10, when the water dispenser meets the preset conditions, the state of the water dispenser is switched to the preset mode;

[0058] An embodiment of the present application provides a method for switching the state of a water dispenser to a preset mode. Specifically, when certain preset conditions are met, the state of the water dispenser is switched to the preset mode. The preset mode indicates that the water dispenser is in a state capable of executing a cold water reflux cycle, and can trigger a cold water reflux instruction or automatically trigger a cold water reflux instruction in response to a control instruction input by a user.

[0059] Exemplarily, the preset mode may be "smart fresh water mode", which means that the water dispenser has the function of intelligently keeping the water fresh and odorless, preparing for the subsequent triggering of the cold water return instruction, and the preset conditions may be pre-set conditions for automatically entering the "smart fresh water mode" or manually controlled conditions for entering the "smart fresh water mode", which may be set according to actual needs.

[0060] In a feasible embodiment, the preset condition may be receiving an ice-making instruction or a cooling instruction, or receiving a mode switching instruction when the water dispenser is in a standby state and the cold water tank is in a water supply state. The ice-making instruction or the cooling instruction may be input by the user by clicking the corresponding function button on the water dispenser, the cold water tank being in a water supply state means that the cold water tank is not in a water shortage state, and the amount of water stored inside can be supplied normally, and the mode switching instruction may be a preset pressing method of the user for the corresponding button of the "smart fresh water mode", such as long pressing for 3 seconds.

[0061] That is, when the user turns on the ice-making or refrigeration function of the water dispenser, the water dispenser automatically enters the "smart fresh water mode"; or, when the water dispenser is in standby and the chiller is not short of water, the "smart fresh water mode" is in the off state, and the user presses and holds the "smart fresh water" button for 3s to enter the "smart fresh water mode".

[0062] Step A20, when the water dispenser is in the preset mode, if a reflux start instruction is received, a cold water reflux instruction is triggered;

[0063] Or, step A30, when the water dispenser is in a preset mode, triggering a cold water reflux instruction based on a preset trigger frequency.

[0064] The embodiment of the present application provides at least two ways of triggering the cold water reflux instruction when the water dispenser is in a preset mode. Step A20 and step A30 are parallel technical solutions, which are two different ways of triggering the cold water reflux instruction.

[0065] For example, when the water dispenser is in the "smart fresh water mode", if a reflux start command is received (such as a short press of the "smart fresh water" button), the cold water reflux command is immediately triggered, so that the water in the cold water tank flows back to the composite filter element for re-filtration. In another case, when the water dispenser is in the "smart fresh water mode", the cold water reflux command is automatically triggered based on a preset trigger frequency. For example, when the water dispenser enters the "smart fresh water mode", the timing starts, and the cold water reflux command is triggered every 3 hours to reflux and filter the water in the cold water tank, wherein the preset trigger frequency can be customized by the user.

[0066] For example, a "smart fresh water" button or icon is provided on the water dispenser, and its specific control method is as follows: after the water dispenser turns on the ice-making or cooling mode and is in the "smart fresh water mode", the icon is fully lit; when the water dispenser turns on the ice-making or cooling mode and does not enter the "smart fresh water mode", the icon is half lit; when the ice-making and cooling modes are not turned on, the icon is off; after the water dispenser enters the "smart fresh water mode", when the cold water reflux operation is in progress inside the water dispenser, the icon flashes. In this way, the user can know the current status of the water dispenser in a timely and accurate manner according to the display status of the icon.

[0067] In one possible embodiment, referring to Figure 2 The schematic diagram of the water circuit principle of the water dispenser, in addition to the water pipe 10, the cold water tank 11, the composite filter element 12 and the pure water tank 13, the water dispenser also includes a water inlet solenoid valve 14 and a first water pump 15. The water inlet solenoid valve 14 is located on the water pipe between the composite filter element 12 and the pure water tank 13, and the first water pump 15 is located on the water pipe between the cold water tank 11 and the composite filter element 12;

[0068] Specifically, the step of controlling the water in the cold water tank to flow to the pure water tank after being filtered by the composite filter element may include:

[0069] Step S11, opening the water inlet solenoid valve;

[0070] Step S12, after the water inlet solenoid valve is opened for a first preset time, the first water pump is turned on to control the water in the cold water tank to flow back to the composite filter element, and the filtered water flows to the pure water tank.

[0071] Among them, the water inlet solenoid valve 14 is located on the water pipe between the composite filter element 12 and the pure water tank 13, and is used to control the flow of water flowing out of the composite filter element 12 and the pure water tank 13. After the water inlet solenoid valve 14 is turned on, the passage between the composite filter element 12 and the pure water tank 13 is opened, so that the water in the cold water tank 11 can flow normally into the composite filter element 12, avoiding excessive pressure and inability of water to be injected into the composite filter element.

[0072] The first water pump 15 is located on the water pipe between the cold water tank 11 and the composite filter element 12, and is used to pump out the cold water in the cold water tank 11 and send it to the composite filter element 12 to filter the cold water again to obtain filtered water. At this time, the water inlet solenoid valve 14 has been opened, so the water filtered by the composite filter element 12 can flow to the pure water tank 13 for storage, so that the clean water in the pure water tank 13 can be sent to the cold water tank 11 later, thereby realizing automatic renewal of the water in the cold water tank 11 and improving the water quality.

[0073] It should be noted that the first preset time length can be a shorter time interval, such as 1s, mainly to enable the water inlet solenoid valve and the first water pump to open successively to avoid excessive pressure after water enters the composite filter element, causing damage to the device or inability to inject water.

[0074] In a possible embodiment, Figure 2 As shown, the cold water tank 11 also includes a water level float 49 and UVC (ultraviolet C band sterilization) 50; the cold water tank 11 is connected to the ice storage bin 47, and can receive the cold water flowing out of the ice storage bin 47. The ice storage bin 47 includes a screw 48 for discharging the made ice cubes from the ice outlet 53; the ice storage bin 47 is connected to the ice making bin 45, and the ice making bin 45 includes an ice making module 46; the composite filter element 12 also includes a front carbon rod 27 and a rear carbon rod 28; and a proximity switch 22 is provided in the pure water tank 13.

[0075] Furthermore, the water dispenser further comprises a second water pump 16, and the second water pump 16 is located on the water pipe between the pure water tank 13 and the cold water tank 11;

[0076] Specifically, the step of controlling the water in the pure water tank to flow to the cold water tank includes:

[0077] Step S21, after the water inlet solenoid valve is opened for a first preset time, the second water pump is turned on to pump the water in the pure water tank to the cold water tank.

[0078] like Figure 2As shown, the second water pump 16 is located on the water pipe between the pure water tank 13 and the cold water tank 11 , and is used to pump water in the pure water tank 13 to the cold water tank 11 .

[0079] Specifically, after the water inlet solenoid valve is turned on for a first preset time (e.g., 1 second), the second pump can be turned on to pump the filtered water in the pure water tank to the cold water tank to renew the water in the cold water tank. The second pump can be turned on at the same time as the first pump to realize the water circulation of the cold water return circuit of the cold water tank-composite filter element-pure water tank-cold water tank. Figure 2 The direction of the arrow in the figure indicates the flow direction of water in the circuit.

[0080] In addition, Figure 2 As shown, the water dispenser also includes the following components: a raw water tank 20, a waste water tank 21, a proximity switch 22 and a float 23 in the raw water tank 21, an RO (Reverse Osmosis) filter element 30, a waste water solenoid valve 24 disposed between the waste water tank 21 and the RO filter element 30, a self-priming pump 26, and a TDS (Total Saturation Direct Current) between the raw water tank 21 and the self-priming pump 26. The present invention also includes a flow chart of the ice making device and the ice making device. The present invention also includes a flow chart of the ice making device and the ice making device. The flow chart of the ice making device and the ice making device are provided with a plurality of channels. The flow chart of the ice making device and the ice making device are provided with a plurality of channels. The flow chart of the ice making device and the ice making device are provided with a plurality of channels.

[0081] Combined with the contents of the above embodiments, the execution process of step S11, step S12 and step S21 is as follows: Figure 3 The step S11 is first executed to open the water inlet solenoid valve, and after the water inlet solenoid valve is opened for a first preset time, the step S12 and the step S21 are simultaneously executed.

[0082] In a feasible embodiment, the water dispenser control method may further include:

[0083] Step B10, when the water dispenser triggers the cold water reflux command, the preset indicator light is turned on, the water outlet function, the water temperature adjustment function and the water volume adjustment function are turned off, and the ice making system and the refrigeration system of the water dispenser are locked in the off state.

[0084] The preset indicator light may be a "cleaning" indicator light, indicating that cold water is currently being refluxed inside the water dispenser. In addition, when the indicator light is on, the water outlet function and water temperature / water volume adjustment function of the water dispenser are turned off and cannot be used normally, but other buttons can be used normally.

[0085] In addition, in order to ensure the operational stability of the ice-making system and the refrigeration system, when the "cleaning" indicator light is on (that is, when the water dispenser is in the internal cold water return cycle), the ice-making system and the refrigeration system of the water dispenser are locked in the closed state, that is, the ice-making system and the refrigeration system are kept in the deactivated state. For example, if the ice-making / refrigeration system is running when the cold water return command is triggered, it will stop running; if it is not in the running state, it will remain in the closed state during the cold water return period and is prohibited from starting.

[0086] The embodiment of the present application provides a method for disabling other functions while the cold water in the cold water tank of the water dispenser is circulating and filtering, thereby ensuring the stability and normal operation of the water dispenser.

[0087] In a feasible embodiment, the water dispenser control method may further include:

[0088] Step C10, when the water dispenser is in the preset mode, if a mode exit command is received, the water dispenser is controlled to exit the preset mode;

[0089] In an embodiment of the present application, a method for exiting a preset mode (e.g., smart fresh water mode) is provided. That is, when the water dispenser is in the preset mode, if a mode exit command input by the user is received at this time (e.g., long pressing the "smart fresh water" button for 3s), the preset mode can be turned off and exited, and the water dispenser can be restored to normal working state.

[0090] Among them, there are two situations for exiting the preset mode in C10. One is the state of being in the preset mode but not triggering the cold water reflux instruction, and directly exiting the preset mode after receiving the mode exit instruction; the other is the state of being in the preset mode and having triggered the cold water reflux instruction, and executing steps S10 to S20. After receiving the mode exit instruction, the cold water reflux process is stopped and the preset mode is exited at the same time.

[0091] Step C20, when the accumulated time after the water dispenser triggers the cold water reflux instruction reaches a second preset time, the cold water reflux in the water dispenser is stopped.

[0092] An embodiment of the present application provides a method for automatically stopping the cold water reflux in a water dispenser, that is, after the water dispenser triggers the cold water reflux instruction and executes step S10 and step S20, if the cumulative duration of the cold water reflux process has reached a second preset duration (such as 8 minutes), the cold water reflux process of the water dispenser is automatically stopped and the normal working state is restored.

[0093] It should be noted that after the accumulated time reaches the second preset time and the cold water reflux is stopped, the water dispenser is still in the preset mode and restarts the timing until the accumulated time reaches the time corresponding to the preset trigger frequency, and the cold water reflux instruction is triggered again. For example, when the preset trigger frequency is 3 hours, the cold water reflux instruction is triggered again 3 hours after the cold water reflux in the water dispenser is stopped, and steps S10 to S20 are executed to circulate and update the cold water in the cold water tank.

[0094] Furthermore, in a feasible embodiment, the water dispenser control method may further include:

[0095] Step C30, after stopping the cold water reflux in the water dispenser, the working states of the ice-making system and the refrigeration system of the water dispenser are restored to the working states before the cold water reflux instruction is triggered.

[0096] It should be noted that, since the refrigeration system and the ice-making system are both in a closed state during the cold water return process of the water dispenser, the working state of the refrigeration system and the ice-making system is restored after the cold water return in the water dispenser is completed.

[0097] The embodiment of the present application provides a control method for automatically returning cold water to a water dispenser to purify the cold water in a cold water tank. It can automatically or allow the user to manually exit a preset mode and the cold water return process, thereby meeting the user's personalized needs in actual usage scenarios and improving the user experience.

[0118] In one embodiment, the backflow stopping module is further configured to:
