In the embodiment of the invention, the water taking requirement of the water dispenser is preferentially considered by arranging the flowmeter at the water inlet of the multi-way water through valve, and the water taking of the water dispenser and the water injection of the ice maker are staggered in time sequence, so that the quantitative water taking of the water dispenser is realized, and the user experience is improved.

Referring to fig. 10, fig. 10 is a flowchart of a water supply control method for a refrigerator according to an embodiment of the present invention, which is implemented by a controller installed in the refrigerator.

The refrigerator 100 is provided with an ice maker 10, a water dispenser 20 is arranged on a door of the refrigerator 100, and the ice maker 10 is used for producing ice cubes; the water dispenser 20 is used for providing drinking water for users, a water tank (not shown in the figure) is also arranged in the chamber of the refrigerator, and the ice maker and the water dispenser are connected with the water tank through a water guide pipe and a multi-way water valve, and the water tank is used for supplying water for the ice maker and the water dispenser. Referring to the schematic diagram of the installation position of the conventional flowmeter shown in fig. 2, a flowmeter is usually arranged on the side of the ice maker to monitor the flow of the ice maker, but quantitative water taking of the water dispenser cannot be realized. Referring to the schematic diagram of the installation position of the flowmeter in the multiple-way water valve shown in fig. 3, the flowmeter 40 is disposed at the water inlet a of the multiple-way water valve 30 for detecting the water inflow, water flows in from the water inlet a of the multiple-way water valve 30, when the drinking water valve of the multiple-way water valve 30 is opened, water flows from the drinking water outlet b of the multiple-way water valve 30 to the drinking water machine for providing drinking water to the user, and when the ice making valve of the multiple-way water valve 30 is opened, water flows from the ice making outlet c of the multiple-way water valve 30 to the ice maker for making ice.

It should be noted that the multiple water-passing valve is not limited to three, and typically, a three-way valve is used.

The refrigerator comprises an ice maker, a water dispenser, a multi-way water through valve and a flowmeter for detecting water inflow, wherein the multi-way water through valve comprises a water inlet, a water drinking outlet connected with the water dispenser and an ice making outlet connected with the ice maker, and the flowmeter is arranged at the water inlet; the ice making control method of the refrigerator comprises the following steps of S1 to S2:

s1, responding to a quantitative water taking instruction, disabling a water filling function of the ice machine, opening a water drinking valve of a multi-way water through valve, closing the water drinking valve until the water inflow of the current quantitative water taking state reaches a preset water drinking threshold value, and relieving the disabling of the water filling function of the ice machine;

s2, responding to an ice making water injection command, opening an ice making valve of the multi-way water valve when the water injection function of the ice making machine is not disabled, and closing the ice making valve until the accumulated water inflow in the current water injection state reaches a preset water injection threshold or a quantitative water taking command is received.

Specifically, in the embodiment of the invention, the controller is used for controlling the water taking of the water dispenser and the water filling of the ice maker, so that it can be understood that the types of the received instructions comprise a quantitative water taking instruction and an ice making water filling instruction. The water taking priority of the water dispenser is higher than that of the ice maker to fill water, so when a quantitative water taking instruction of a user is received, the water filling function of the ice maker is temporarily disabled in response to the quantitative water taking instruction, the ice making valve is in a closed state when the water dispenser takes water, the water drinking valve of the multi-way water valve is opened, the quantitative water taking state is entered, and all water entering the water inlet of the multi-way water valve flows from the water drinking outlet to the water dispenser to provide drinking water for the user; when the water inflow in the current quantitative water taking state is detected to reach the preset water drinking threshold, the water drinking task of the water dispenser is finished, so that the water dispenser is closed, the disabling of the water filling function of the ice machine is released, and the ice machine can determine whether to fill water according to actual requirements.

Specifically, the ice maker is cycled and repeatedly operated, the ice maker is cycled and operated according to the sequence of water injection, ice making and ice turning until the ice is full, the generation of an ice making water injection command is generated in combination with the ice amount state at fixed time, the generation time of the ice making water injection command can be prejudged and not felt by a user, and the ice making water injection command can be delayed or suspended within a certain time, so that compared with the quantitative water taking of the water dispenser, the ice making flow monitoring priority is lower, when the ice making water injection command is received, if the water injection function of the ice maker is forbidden, the quantitative water taking of the water dispenser is performed at the moment, the water injection function of the ice maker is forbidden, the forbidden when the water injection function of the water dispenser is detected, the water inlet is not performed at the moment, the water drinking valve is in a closed state, and the ice making valve can be opened to enable water at the water inlet to flow from the ice making outlet to the ice maker; the water injection process of the ice machine is in the same water injection state, for example, the water injection process of the ice machine is supposed to be interrupted by the water dispenser, the water injection state before interruption and the water injection state after interruption are in the same water injection state, when the accumulated water inflow of the current water injection state reaches a preset water injection threshold value, the ice making valve is closed, the current water injection state is ended, or when a quantitative water taking instruction is received, the ice making valve is temporarily closed, the current water injection state at the moment is not ended, and the ice making machine is only in a pause state, so that the quantitative water taking function of the water dispenser is preferentially executed.

It should be noted that, the preset water intake threshold is set by the user, the user inputs the target water intake, the controller receives the target water intake input by the user and sets the target water intake as the preset water intake threshold, where the user may input the target water intake through a display screen provided on the refrigerator, or the refrigerator manufacturer may preset a plurality of water intake, the user selects the preset water intake, the controller receives the selection ice making input by the user to determine the preset water intake threshold, and it is understood that the setting of the preset water intake threshold is not limited to the specific setting mentioned above, but is not limited thereto.

It should be noted that, the preset water injection threshold is preset by the refrigerator manufacturer according to the ice making function of the ice maker when the ice maker is designed.

In the embodiment of the invention, the flowmeter is arranged at the water inlet of the multi-way water through valve and is used for detecting the water inflow, and the water inflow obtained by monitoring the flowmeter is only the water inflow of the water dispenser or the water inflow of the ice maker by taking the water of the water dispenser and staggering the quantitative water taking of the water dispenser and the water inflow of the ice maker by giving priority to water taking of the water dispenser, so that the multi-way water flow is monitored by one flowmeter, the quantitative water taking of the water dispenser and the quantitative water inflow of the ice maker are both considered, and the user experience is improved.

Specifically, regarding the quantitative water taking of the water dispenser and the control of water injection of the ice maker, the quantitative water taking of the water dispenser is performed by responding to a quantitative water taking instruction, the water injection of the ice maker is performed by responding to an ice making water injection instruction, the ice maker circularly and repeatedly works, and the water injection time is not more than 12 seconds each time (specific time is only referred); the quantitative drinking water is operated by a user, for example, 500ml of water can exceed 1 minute, if the user continuously takes water, and can take a plurality of minutes, the water taking requirement of the water dispenser and the water filling requirement of the ice maker are likely to occur simultaneously, so that the response of the instruction needs to be controlled, and the specific control process is as follows.

S103, when the ice maker is in a water injection state, closing an ice making valve of the multi-way water through valve, disabling a water injection function of the ice maker, and recording water inflow under the current water injection state; and opening the drinking water valve to enable water entering from the water inlet to flow from the drinking water outlet to the water dispenser, closing the drinking water valve until the water inflow in the current quantitative water taking state reaches the preset drinking water threshold value, and removing the disabling of the water injection function of the ice machine.

It can be appreciated that the water injection condition of the ice machine includes a water injection state indicating that the ice machine is injecting water and a water injection stop state indicating that the ice machine is not injecting water at this time.

Specifically, when a user inputs a quantitative water taking instruction, the water inlet valve is detected to be not filled by the ice machine, the water filling function of the ice machine is immediately started, the water filling function of the ice machine is forbidden, the ice machine is not allowed to fill water, the quantitative water taking state is entered, at the moment, all water entering from the water inlets of the multi-way water inlet valve flows to the water dispenser from the water outlet, water is supplied to the user, and as the water in the quantitative water taking state flows to the water dispenser, the water inflow monitored by the flowmeter is the actual water intake of the water dispenser, when the water inflow in the current quantitative water taking state reaches a preset water drinking threshold value, the quantitative water taking is finished, the water drinking valve is closed, the current quantitative water taking state is exited, the forbidden of the water filling function of the ice machine is released, and the ice machine is allowed to fill water. When a user inputs a quantitative water taking instruction, the ice maker is just filled with water, the ice making valve is closed, the water filling function of the ice maker is disabled, the water filling of the ice maker is paused, the water inflow in the current water filling state is recorded and stored, and then the water drinking valve is opened so that water entering from the water inlets of the multi-way water drinking valve flows to the water drinking machine from the water drinking outlet to supply water for the user.

In this embodiment, it can be understood that the quantitative water intake of the water dispenser is active and random for the user, and in order to ensure the user experience, the quantitative water intake instruction input by the user is immediately responded after the quantitative water intake instruction is received, so that quantitative water supply is preferentially performed for the user.

In one embodiment, the water injection of the ice maker is controlled specifically through steps S201 to S202:

Specifically, the states of the ice maker water injection function include disabled and disabled, ice maker water injection is not allowed when the ice maker water injection function is disabled, and ice maker water injection is allowed when the ice maker water injection function is not disabled. When the water injection requirement of the ice machine exists, whether the water injection function of the ice machine is forbidden or not is judged first, and when the water injection function is forbidden, the water taking of the water dispenser is performed at the moment, and the water injection of the ice machine can be performed only after the forbidden water injection function of the ice machine is released after the water taking of the water dispenser is waited to be completed. The water injection of the ice machine is continuously performed until the water inflow of the current water injection state reaches a preset water injection threshold value, or the water injection of the ice machine is interrupted in the water injection process, the water injection quantity of the ice machine is recorded at the moment, and after the water injection of the water machine is completed, the water injection of the ice machine is continuously performed, and the water injection quantity recorded during the interruption of the water injection of the ice is continuously accumulated until the accumulated water inflow reaches the preset water injection threshold value, so that the current water injection state is exited.

In this embodiment, through setting up the flowmeter in the water inlet department of multichannel water valve, be used for detecting the inflow, can understand, the ration water intaking of water dispenser is initiative and random for the user, and the ice maker water injection opportunity can prejudge and the user can not feel, consequently, through taking water into the water dispenser in priority, just carry out the water injection of ice maker when making ice water injection function not forbidden, stagger water dispenser ration water intaking and ice maker water injection, realize that a flowmeter carries out multichannel discharge's monitoring, compromise the ration water intaking of water dispenser and the ration water injection of ice maker, user experience has been improved.
