Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a refrigerator, and the refrigerator can be a two refrigerator that open the door, and the refrigerator also can be a single refrigerator that opens the door or a three refrigerator that opens the door, and this application embodiment does not do the restriction to this.

Referring to fig. 1, fig. 1 is a schematic view of a partial structure of a refrigerator according to an embodiment of the present application. The refrigerator includes a cabinet 100 and an ice making device 300. A refrigerating compartment 11 such as a refrigerating compartment 11a, a freezing compartment 11b, or a wide temperature changing compartment is provided in the case 100, and the ice making device 300 is provided in the refrigerating compartment 11.

Referring to fig. 2, the ice making device 300 includes a housing assembly and an ice making mechanism 32. The housing assembly is provided with an ice making chamber, an ice making mechanism 32 is disposed in the ice making chamber, and the ice making mechanism 32 is used for containing water and making the water carried by the water into ice cubes.

In the embodiment of the present application, as shown in fig. 2, the refrigerating compartment 11 includes a refrigerating compartment 11a and a freezing compartment 11b, the ice making device 300 is disposed in the refrigerating compartment 11a, and the ice making compartment is communicated with the refrigerating compartment 11a, and a first passage 12 communicating the freezing compartment 11b and the refrigerating compartment 11a is disposed in the box 100, so that the refrigerator can directly blow cold air in the freezing compartment 11b into the ice making compartment to freeze water carried by the ice making mechanism 32 in the ice making compartment to form ice cubes.

For example, the ice making mechanism 32 may include an ice making compartment 321, the ice making compartment 321 is provided with a receiving compartment for receiving water, a water injection pipe may be disposed above the ice making compartment 321, so that water conveyed by the water injection pipe can directly flow into the receiving compartment, and the water in the receiving compartment can be frozen to form ice cubes under the effect of cold air blown from the freezing compartment 11b to the ice making compartment 321.

The ice making mechanism 32 may further include a torsion motor for driving the rotation of the ice making housing 321 to pour out the ice cubes made in the receiving groove.

It is understood that the refrigerator may include the first ice bank 13 to receive the ice cubes discharged from the ice making mechanism 32.

With continued reference to fig. 2, the first ice bank 13 is disposed in the freezing chamber 11b and opens toward the first passage 12, so that the ice cubes discharged from the ice making mechanism 32 can directly fall into the first ice bank 13 along the first passage 12 under its own weight. Meanwhile, since the temperature in the freezing chamber 11b is low, it is also possible to ensure that the ice cubes in the first ice bank 13 do not melt by the low temperature in the freezing chamber 11 b.

The first ice bank 13 may include a drawer provided to the freezing chamber 11b, and the drawer may be drawn out of the freezing chamber 11b to take ice during use by a user.

Referring to fig. 3, in the embodiment of the present application, the ice making apparatus 300 may further include a second ice bank 312 and an ice transporting mechanism 33. The second ice bank 312 may be located at an upper side of the ice making mechanism 32 in a gravity direction, and the ice transporting mechanism 33 serves to transport at least a portion of the ice cubes discharged from the ice making mechanism 32 to the second ice bank 312 to store a small amount of ice cubes for a short period of time.

Further, at least a portion of the ice cubes discharged from the ice making mechanism 32 may be transported to the top of the ice making device 300 by the ice transporting mechanism 33, so that the parts inside the ice making device 300 may be more flexibly set, or so that the ice making device 300 may be flexibly mounted to various locations on the refrigerator.

In addition, when the refrigerator further includes the first ice bank 13, that is, when the refrigerator includes two ice banks, ice cubes discharged from the ice making mechanism 32 may be transported into the second ice bank 312 by the ice transporting mechanism 33, or may be directly dropped into the first ice bank 13 by its own weight. It will be appreciated that the two ice banks configuration can greatly increase the ice storage capacity of the refrigerator on the one hand, and on the other hand, different ice banks can be used for different processing of ice pieces, such as the first ice bank 13 can be designed to have a larger volume to store a larger amount of ice pieces, while the second ice bank 312 can be used to movably interface with the automatic ice discharging mechanism 34 to automatically deliver the ice pieces in the second ice bank 312 to the outside of the refrigerator through the automatic ice discharging mechanism 34.

For the convenience of the user, in the embodiment of the present application, the ice making device 300 further includes an ice discharging mechanism 34, and the ice discharging mechanism 34 is used for delivering the ice cubes in the second ice bank 312 to the outside of the refrigerator, so that the user can take the ice without opening the refrigerator door 200.

Referring to fig. 7, the refrigerator is provided with an ice outlet 21 and an ice outlet valve 35, the ice outlet 21 is used for communicating the ice making device 300 with the outside of the refrigerator, and the ice outlet valve 35 is rotatably disposed at the ice outlet 21 to open or close the ice outlet 21. When the user takes ice, the ice outlet valve 35 opens the ice outlet 21 to enable the ice outlet mechanism 34 to deliver ice cubes from the ice outlet 21 to the outside of the refrigerator; after the ice is taken out, the ice outlet valve 35 closes the ice outlet 21 to isolate the inside of the refrigerator from the outside of the refrigerator, so that the temperature inside the refrigerator is prevented from rising due to the heat outside the refrigerator entering the inside of the refrigerator.

For example, in the embodiments of the present application, please refer to fig. 4, 5 and 6 in combination, the ice discharging mechanism 34 includes an ice pushing assembly and an ice crushing assembly. The housing assembly comprises an ice storage chamber 312a and an ice crushing chamber 314 communicated with the ice storage chamber 312a, the ice pushing assembly comprises an ice pushing motor 341 and an ice pushing screw 342 arranged in the ice storage chamber 312a, and the ice pushing motor 341 is used for driving the ice pushing screw 342 to drive so as to push ice cubes in the ice storage chamber 312a into the ice crushing chamber 314. The ice crushing assembly includes an ice crushing motor 343 and an ice blade structure disposed in the ice crushing chamber 314, and the ice crushing motor 343 is configured to drive the ice blade structure to rotate to discharge ice cubes from the ice crushing chamber 314 in a whole ice form or a crushed ice form.

Wherein, the ice storage chamber 312a may be an ice storage space formed by the second ice bank 312, the ice pushing screw 342 is disposed in the second ice bank 312, and a sidewall of the second ice bank 312 is provided with a first outlet 312b for communicating with the ice crushing chamber 314. Specifically, during the pushing of ice, the ice pushing motor 341 drives the ice pushing screw 342 to apply a force to the ice cubes inside the second ice bank 312 to push the ice cubes to move from the first outlet 312b into the ice crushing chamber 314.

Wherein, the wall body of the ice crushing chamber 314 is provided with a second outlet 313a for communicating with the ice outlet 21, and an ice inlet passage 313b for communicating with the ice storage chamber 312a is connected. The ice blade structure may include a rotating shaft 346, a moving ice blade 344 and a fixed ice blade 345, the rotating shaft 346 is connected with an output shaft of the ice crushing motor 343 (either directly or through a transmission structure), the moving ice blade 344 is fixedly connected with the rotating shaft 346, one end of the fixed ice blade 345 is fixed on the inner wall of the ice crushing chamber 314, and the other end is sleeved on the rotating shaft 346.

Specifically, taking the initial ice pieces entering the ice crushing chamber 314 as whole ice as an example, when the rotation shaft 346 rotates in the first direction, the movable ice blade 344 may push the whole ice to be directly discharged from the second outlet 313a, so that the ice blade structure can discharge the whole ice from the ice crushing chamber 314. When the rotating shaft 346 rotates in the second direction, the movable ice blade 344 may push the whole ice toward the fixed ice blade 345 first, so that the movable ice blade 344 and the fixed ice blade 345 cooperate to cut the whole ice into crushed ice, and then the movable ice blade 344 continues to push the crushed ice, so that the crushed ice is discharged from the second outlet 313 a. Furthermore, in the ice discharging process, the function of ice making or ice crushing can be realized through the matching of the movable ice blade 344 and the fixed ice blade 345, so as to meet different ice taking requirements of users.

Since different users have different installation requirements on the refrigerator, some users tend to install the refrigerator in the cabinet in an embedded manner, and some users tend to arrange the refrigerator in an open manner, in order to ensure that the user can conveniently take ice in any assembled state of the refrigerator, in one embodiment, the ice outlet 21 is preferably disposed on the door 200 of the refrigerator.

In this embodiment, the housing assembly includes a first housing 311 and a second housing 313, the first housing 311 is disposed in the refrigerating compartment 11a, and the second housing 313 is mounted to the door 200. The ice making mechanism 32 and the second ice bank 312 are disposed in the first housing 311, the ice pushing assembly of the ice discharging mechanism 34 is disposed in the first housing 311, the ice crushing assembly of the ice discharging mechanism 34 is disposed in the second housing 313, and the second housing 313 is provided with the ice crushing chamber 314.

Second housing 313 may include a first inner wall 315 that encloses ice debris chamber 314. The first inner wall 315 includes a first annular wall 316, and a center line of the first annular wall 316 is parallel to the gravity direction, or the first annular wall 316 is vertically disposed. The second outlet 313a is disposed on a side of the first inner wall 315 facing the door 200, and at least a portion of the second outlet 313a is disposed on the first annular wall 316. The rotating shaft 346 is arranged along the gravity direction, and the rotating shaft 346 can drive the ice blade 344 to drive the ice cubes in the ice crushing chamber 314 to rotate around the axial direction of the ice cubes to be discharged at the second outlet 313 a.

Specifically, when the door 200 is in the closed state, the second housing 313 is abutted with the first housing 311 so that the ice crushing chamber 314 can communicate with the first outlet 312b of the second ice bank 312 through the ice inlet passage 313b to enable the ice pushing assembly to push the ice pieces in the second ice bank 312 into the ice crushing chamber 314; when the door 200 is in the opened state, the second housing 313 is separated from the second housing 313, and the ice crushing chamber 314 is disconnected from the second ice bank 312.

The second housing 313 further includes an ice discharge passage 313c connected to the ice crushing chamber 314, and one end of the ice discharge passage 313c communicates with the second outlet 313a and the other end communicates with the ice outlet 21. In order to allow the ice cubes in the ice discharge passage 313c to be more smoothly discharged, the ice discharge passage 313c is inclined downward in the gravity direction along the inlet toward the outlet of the ice discharge passage 313 c. And then the whole ice or the crushed ice in the ice crushing chamber 314 can slide out under the action of the gravity of the ice crushing chamber when entering the ice outlet channel 313c, so that the ice blocks are prevented from being accumulated in the ice outlet channel 313c and cannot be discharged, and finally, the user can take the ice more conveniently.

In an embodiment of the present application, referring to fig. 2, the refrigerator further includes a water supply device 400, the water supply device 400 is disposed in the cabinet 100, the water supply device 400 is used to be connected to an external water source, and the water supply device 400 is connected to the ice making device 300 to supply water required for making ice cubes to the ice making device 300.

The water supply device 400 is arranged in the refrigerating chamber 11a and at one side of the refrigerating device, on one hand, the distance between the water supply device 400 and the ice making device 300 is closer, so that a pipeline for supplying water to flow between the water supply device 400 and the ice making device 300 can be shorter or even directly cancelled, so that the water route wiring in the refrigerating chamber 11 is simpler, and the installation difficulty of the refrigerator is further reduced; on one hand, the water supply device 400 is installed in the refrigerating chamber 11a following the ice-making device 300, and the water in the water supply device 400 can be pre-cooled through the refrigerating chamber 11a, thereby increasing the ice-making speed of the ice-making device 300.

For example, in the embodiment of the present application, referring to fig. 8, the water supply device 400 includes a water valve 41, the water valve 41 has a water inlet valve opening 411 and a water filling valve opening 412, the water inlet valve opening 411 is used for communicating with an external water source, and the water filling valve opening 412 is connected with the ice making device 300 to supply water to the ice making mechanism 32.

Then, drinking water such as tap water may be introduced into the water valve 41 through the water inlet valve opening 411, and then, may be injected into the ice making device 300 through the water filling valve opening 412, so that the ice making mechanism 32 may obtain water required for making ice cubes.

Specifically, the water inlet valve opening 411 may be in a normally open state, and the water filling valve opening 412 is controlled to be opened or closed according to a water filling signal, and when the water valve 41 receives a signal for filling water into the ice making device 300, the water filling valve opening 412 is controlled to be opened, so that an external water source enters the ice making device 300 through the water inlet valve opening 411 and the water filling valve opening 412.

It is understood that the refrigerator determines whether the ice making device 300 needs to be filled with water by determining whether the ice making mechanism 32 (in the ice making compartment) has ice cubes, for example, a sensor may be disposed inside the ice making device 300 to detect whether the ice making mechanism 32 has ice cubes, and when the ice making mechanism 32 has no ice cubes, a water filling signal is output to control the water supply device 400 to fill the ice making mechanism 32 with water, that is, the water filling signal is automatically input to the sensor inside the refrigerator without manual input of a user.

The refrigerator may be provided with a detection device to detect whether the water level in the ice cube tray reaches a preset water level during the water injection of the ice making mechanism 32. For example, the detection device may be a water level sensor, and when the water level sensor detects that the water level in the ice cube tray reaches a preset water level, the water filling valve port 412 is controlled to be closed.

In the embodiment of the present application, the water inlet valve opening 411 is directly connected to a household tap water pipe, the tap water has a certain water pressure, and when the water inlet valve opening 412 is opened, the tap water can be automatically injected into the ice making mechanism 32 under the action of the water pressure.

Since the pressure of the domestic tap water is usually constant, the time for filling water to one ice making mechanism 32 is constant each time, so that the opening time of the water filling valve port 412 can be set, and in the process of filling water to the ice making mechanism 32, when the water filling time length is equal to the opening time, the water filling valve port 412 is controlled to be closed, and at this time, the ice making mechanism 32 just obtains the water required for making ice cubes.

It should be noted that, when the number of the ice making mechanisms 32 is multiple, the number of the water filling valve ports 412 is multiple, and the multiple water filling valve ports 412 are in one-to-one correspondence with the multiple ice making mechanisms 32, that is, each water filling valve port 412 is used for separately filling water to the corresponding ice cube tray, that is, the water filling process of each ice making mechanism 32 is independent.

In order to further enrich the use function of the refrigerator, in the embodiment of the present application, the water supply device 400 further includes a water storage tank 42 and a dispenser 43. The water valve 41 further has a water intake valve port 413, the water storage tank 42 is communicated with the water intake valve port 413 to contain water supplied from the water valve 41, and the water storage tank 42 is connected with the dispenser 43 to output water in the water storage tank 42.

Then, the drinking water such as tap water can enter the water valve 41 through the water inlet valve opening 411, and then enter the water storage tank 42 through the water outlet valve opening 413, and is outputted to the outside of the refrigerator through the dispenser 43. It can be understood that since the water storage tank 42 can contain a certain amount of water and be placed in the refrigerating chamber 11a for a sufficient time to form ice water, and the ice making device 300 does not need to take ice water from the water storage tank 42, a user can take sufficient ice water from the water storage tank 42 through the dispenser 43.

So, the user not only can obtain whole ice or garrulous ice through ice making device 300, can also obtain frozen water through water supply installation 400 to make the user directly obtain the frozen water mixture through the refrigerator, further satisfy user's user demand, enrich the service function of refrigerator, promote user's use and experience.

The distributor 43 is mounted on the box door 200, the distributor 43 is provided with a water outlet 422, and the water outlet 422 is communicated with the water storage tank 42 through a first water pipe 423. For the convenience of the user, the ice outlet 21 may be directly disposed on the dispenser 43, that is, the water outlet 422 and the ice outlet 21 are both disposed on the dispenser 43, so that the user can take ice and water through the dispenser 43, further facilitating the user.

As shown in fig. 2, the water supply device 400 is disposed on a side of the first housing 311 opposite to the opening of the refrigerating chamber 11a, so that the water supply device 400 can be blocked by the housing, and the inside of the refrigerating chamber 11a is neater and more beautiful after the door 200 is opened.

Referring to fig. 8, a closed installation cavity 311a is defined by a side of the first housing 311 away from the opening of the refrigerating compartment 11a and an inner surface of the inner container of the box 100, the installation cavity 311a is independent from the ice making compartment, and the water supply device 400 is accommodated in the installation cavity 311 a. Thus, cold air entering the ice making chamber can exchange heat with the mounting cavity 311a through the first shell 311 to a certain extent, so that the temperature in the mounting cavity 311a is reduced, the water supply device 400 in the mounting cavity 311a is refrigerated, and a user can obtain ice water; meanwhile, cold air entering the ice making chamber can be prevented from directly blowing to the water supply device 400, so that the water in the water supply device 400 is prevented from being frozen due to the fact that the temperature in the mounting cavity 311a is too low.

In the embodiment of the present application, the water storage tank 42 includes a water inlet 421 and a water outlet 422, the water inlet 421 is communicated with the water intake valve port 413, the water outlet 422 is connected with the dispenser 43 through a first water pipe 423, and then the water in the water storage tank 42 can be output to the dispenser 43.

Specifically, the water inlet valve 411 is in a normally open state, the water outlet valve 413 is controlled to open or close according to a water outlet signal, and when the water valve 41 receives a water outlet signal, the water outlet valve 413 is controlled to open, so that an external water source enters the water storage tank 42 through the water inlet valve 411 and the water outlet valve 413, and ice water in the original water storage tank 42 is pressed out under the action of water pressure, and is conveyed to the distributor 43 through the first water pipe 423 for output.

The embodiment of the application provides a control method of a refrigerator. Specifically, the control method is applied to a refrigerator having an ice making function therein, and the embodiment of the present application will explain the control method of the refrigerator by taking the refrigerator based on the inventive concept as an example.

Referring to fig. 9, fig. 9 is a flowchart of a control method of a refrigerator according to an embodiment of the present disclosure, and as shown in fig. 9, the control method of the embodiment includes the following steps:

101: and if the refrigerator obtains an ice taking signal, controlling the ice pushing motor and the ice crushing motor to be started, wherein the ice pushing motor is used for pushing ice blocks to the ice crushing motor, and the ice crushing motor is used for pushing the ice blocks out of the refrigerator in a whole ice form or an ice crushing form.

The ice-fetching signal comprises a whole ice-fetching signal and a crushed ice-fetching signal, and the ice-fetching signal obtained by the refrigerator can be obtained by means of external input, for example, the refrigerator can be provided with a button, and when a user presses the button, the ice-fetching signal can be input to a control system of the refrigerator. For example, the buttons may include a first button and a second button, and the control system of the refrigerator outputs a ice-leveling signal when the user presses the first button for a long time and outputs a ice-breaking signal when the user presses the second button for a long time.

The refrigerator comprises a controller, wherein when the controller receives the ice taking signal, the controller determines the type of ice to be taken out according to the received ice taking signal, and then the controller controls the refrigerator to execute corresponding operation.

In the refrigerator provided above as an example, specifically, when the ice fetching signal is to fetch ice, the controller controls the ice pushing motor 341 to rotate forward, and controls the ice crushing motor 343 to drive the rotating shaft 346 to rotate in the first direction, in this process, the ice pushing motor 341 drives the ice pushing screw 342 to transmit, so that the ice cubes in the ice storage chamber 312a are pushed by the ice pushing screw 342 to move toward the first outlet 312b until entering the ice crushing chamber 314 from the first outlet 312b, and at this time, the rotating shaft 346 drives the movable ice blade 344 to rotate in the first direction, so that the movable ice blade 344 discharges the ice cubes directly from the second outlet 313a, thereby discharging the ice.

When the ice fetching signal is to fetch crushed ice, the controller controls the ice pushing motor 341 to rotate forward, and controls the ice crushing motor 343 to drive the rotating shaft 346 to rotate in a second direction, which is opposite to the first direction, in the process, the ice pushing motor 341 drives the ice pushing screw 342 to transmit, so that the ice cubes in the ice storage chamber 312a are pushed by the ice pushing screw 342 to move towards the first outlet 312b until the ice cubes enter the ice crushing chamber 314 from the first outlet 312b, at this time, the rotating shaft 346 drives the movable ice blade 344 to rotate in the second direction, so that the movable ice blade 344 pushes the ice cubes to the fixed ice blade 345, so that the movable ice blade 344 and the fixed ice blade 345 cooperate to cut the whole ice into crushed ice, and then the movable ice blade 344 continues to push the crushed ice to discharge the crushed ice from the second outlet 313a, thereby discharging the crushed ice.

102: and if the refrigerator obtains an ice taking finishing signal, controlling the ice pushing motor and the ice crushing motor to stop rotating.

The ice-taking-over ending signal obtained by the refrigerator may be obtained by an external input, for example, a user inputs the ice-taking-over signal to the refrigerator by pressing a long button, and when the user releases the pressing of the button, the ice-taking-over ending signal is input to the refrigerator.

It can be understood that the ice-taking ending signal is obtained in the mode, and compared with the mode of setting ice-taking time, the ice-taking amount can be controlled according to the subjective requirements of users, the use requirements of different users can be met, and the use experience of the users is improved.

103: and controlling the ice pushing motor and the ice crushing motor to reversely rotate for a first time.

Specifically, after the rotation of the ice pushing motor 341 and the ice crushing motor 343 is stopped, the adjacent ice pieces in the ice storage chamber 312a near the first outlet 312b are easily frozen together, and when the ice pushing motor 341 and the ice crushing motor 343 are operated next time, the frozen ice pieces are not smoothly pushed out from the first outlet 312b, so that the first outlet 312b is blocked, and the ice pieces are in contact with the ice pushing screw 342, so that a large resistance is generated to the ice pushing screw 342 when the ice pushing motor 341 is started next time, and the ice pieces are easily burned out due to overload. The ice crushing chamber 314 is prone to have ice clamped between the movable ice blade 344 and the fixed ice blade 345 or between the movable ice blade 344 and the inner wall of the ice crushing chamber 314, so that the ice crushing blade is in a stressed state, and the ice crushing motor 343 is in a stressed state.

In this step, after the rotation of the ice pushing motor 341 and the ice crushing motor 343 is stopped, the ice pushing motor 341 and the ice crushing motor 343 are controlled to rotate reversely, so that the ice pushing screw 342 will drive a part of ice cubes to move away from the first outlet 312b (i.e. move backwards), so that the ice cubes close to the first outlet 312b are away from the first outlet 312b, and the ice cubes close to the first outlet 312b are prevented from being condensed together, and further, since the retracted ice cubes are located at the rear side of the ice pushing screw 342, there is no blocking of the ice cubes at the front side of the ice pushing screw 342, when the ice pushing screw 342 is started next time, one side of the ice pushing screw 342 in the transmission direction will not be subjected to the resistance of the ice cubes, so as to avoid the situation that the ice pushing motor 341 is overloaded and burned due to an excessive starting current; meanwhile, when the ice crushing motor 343 rotates reversely, the movable ice blade 344 rotates in a direction away from the ice blocks, so that the ice blocks are prevented from being clamped between the movable ice blade 344 and the fixed ice blade 345, and the ice blocks are prevented from being clamped between the movable ice blade 344 and the inner wall of the ice crushing chamber 314, so that the movable ice blade 344 is in an unstressed state, and the movable ice blade 344 does not have resistance when being started next time because the ice blocks are not in contact with the movable ice blade 344, so that the situation that the ice crushing motor 343 is overloaded and burnt due to overlarge starting current of the ice crushing motor 343 is avoided.

It should be noted that, the reverse rotation of the ice-crushing motor 343 refers to controlling the rotation of the ice-crushing motor 343 in the direction opposite to the rotation direction in the previous operation, for example, when the ice-crushing motor 343 performs the ice-trimming operation in the previous operation, since the ice-crushing motor 343 rotates in the first direction, the ice-crushing motor 343 is controlled to rotate in the direction opposite to the first direction (i.e. the second direction) in the reverse rotation; when the ice-crushing operation is performed by operating the ice-crushing motor 343 last time, since the ice-crushing motor 343 is rotated in the second direction, the ice-crushing motor 343 is controlled to rotate in the direction opposite to the second direction (i.e., the first direction) when the reverse rotation is performed.

Wherein the first time period may be between 0.2 seconds and 1 second.

In order to facilitate the user to take ice without opening the refrigerator door 200, the refrigerator includes an ice outlet passage 313c and an ice outlet valve 35, the ice outlet passage 313c has an ice inlet and an ice outlet 21 opposite to each other, the ice inlet communicates with the ice crushing chamber 314, the ice outlet 21 communicates with the outside of the refrigerator, and the ice outlet valve 35 is rotatably disposed at the ice outlet 21 to open or close the ice outlet 21.

Therefore, in the control method of the refrigerator provided by the embodiment of the present application, before the refrigerator obtains the ice fetching signal and controls the ice pushing motor 341 and the ice crushing motor 343 to be started, the ice outlet valve 35 is controlled to be opened, so that the ice outlet valve 35 communicates the outside of the refrigerator with the ice crushing chamber 314, and the ice cubes in the ice storage chamber 312a can be discharged sequentially through the ice crushing chamber 314 and the ice outlet channel 313 c; after the refrigerator is controlled by the ice-fetching signal to stop the rotation of the ice-pushing motor 341 and the ice-crushing motor 343, the ice-discharging valve 35 is controlled to be closed, so that the ice-discharging valve 35 isolates the outside of the refrigerator from the ice-crushing chamber 314, and the heat of the outside is prevented from entering the refrigerator through the ice-discharging passage 313c, thereby preventing the ice cubes from melting due to the temperature rise in the refrigerator.

Since some users tend to install the refrigerator in the cabinet in an embedded manner, if the ice outlet 21 is formed in the sidewall of the refrigerator body 100, the refrigerator cannot be used for taking ice, in order to improve the universality of the refrigerator, the refrigerator can be conveniently used for taking ice in any assembling state, so that the use requirements of most users are met, the refrigerator comprises a refrigerator door 200, and the ice outlet 21 is formed in the refrigerator door 200.

In the control method of the refrigerator provided in this embodiment, if the refrigerator obtains the ice-fetching signal, the controlling the ice pushing motor 341 and the ice crushing motor 343 to be started includes:

if the box door 200 is in the open state, the ice pushing motor 341 and the ice crushing motor 343 are controlled not to be started;

if the door 200 is in the closed state, the ice pushing motor 341 and the ice crushing motor 343 are controlled to be activated.

In this way, when the door 200 is in the opened state, the ice storage chamber 312a and the ice crushing chamber 314 are in the separated state, and the first outlet 312b of the ice storage chamber 312a is not communicated with the first inlet of the ice crushing chamber 314, the control method of the refrigerator of this embodiment can prevent ice cubes from directly falling from the first outlet 312b of the ice storage chamber 312a by controlling the ice pushing motor 341 and the ice crushing motor 343 to be inactivated.

Also, it should be noted that, when the refrigerator is in the ice-taking state, if the user opens the door 200 by accident, the ice pushing motor 341 and the ice crushing motor 343 are controlled to be immediately stopped at this time, thereby preventing ice cubes from falling from the first outlet 312b of the ice storage compartment 312 a.

It is understood that the refrigerator may be provided with a sensor to detect whether the door 200 is in the opened state or the closed state. For example, the refrigerator may be provided with a laser sensor or an infrared sensor.

Referring to fig. 10, fig. 10 is another flowchart of the control method of the refrigerator provided in the present application, the control method of the refrigerator includes steps 201 to 206, wherein steps 202 and 204 are the same as steps 102 and 103 of the control method of the refrigerator, and are not repeated herein. The rest steps are as follows:

201: and if the refrigerator obtains an ice taking signal, controlling the ice pushing motor to start, and controlling the ice crushing motor to start after waiting for a third time.

Then, the starting time of the ice crushing motor 343 is later than the starting time of the ice pushing motor 341, that is, the ice pushing motor 341 is started first and the ice crushing motor 343 is started later. By the arrangement, the situation that the starting current is overlarge due to the fact that the two motors are started simultaneously can be avoided, and the circuit can be protected.

Wherein the third time period may be between 0.2s and 1 s.

202: and if the refrigerator obtains an ice taking finishing signal, controlling the ice pushing motor and the ice crushing motor to stop rotating.

203: and stopping the ice pushing motor and the ice crushing motor for waiting for a second time.

It can be understood that, before the ice pushing motor 341 and the ice crushing motor 343 are controlled to rotate reversely for a first time period, the ice pushing motor 341 and the ice crushing motor 343 are controlled to stop for a second time period, that is, by stopping the ice pushing motor 341 and the ice crushing motor 343 for the second time period, and then controlling the ice pushing motor 341 and the ice crushing motor 343 to rotate reversely, instead of controlling the two motors to rotate reversely immediately after the ice pushing motor 341 and the ice crushing motor 343 are stopped, the ice pushing motor 341 and the ice crushing motor 343 can be protected, and the service lives of the ice pushing motor 341 and the ice crushing motor 343 can be prolonged.

Wherein the second time period may be between 0.1 second and 0.5 second.

204: and controlling the ice pushing motor and the ice crushing motor to reversely rotate for a first time.

205: and controlling the ice outlet valve to be closed after waiting for the fourth time.

It can be understood that, when the ice crushing motor 343 operates in reverse rotation, there is a situation where the ice cubes that have not been discharged from the second outlet in the ice crushing chamber are pushed again and discharged from the second outlet, and the method of this step controls the ice discharging valve to be closed after the ice crushing motor stops rotating in reverse rotation and waits for a certain time, so that the ice cubes discharged from the second outlet can be smoothly discharged, and the ice discharging valve is prevented from being closed too early and falling onto the ice discharging valve.

Referring to fig. 11, fig. 11 is another flowchart of a control method of a refrigerator provided in the present application, in the control method of the refrigerator provided in the embodiment of the present application, the control method further includes:

301: if the refrigerator obtains a water getting signal, the water getting valve port 413 is controlled to be opened.

The water intake means that the user takes ice water through the water storage tank 42 of the water supply device 400 of the refrigerator. For example, the refrigerator may be provided with a third button, and when the user presses the third button for a long time, the water getting signal can be input to the control system of the refrigerator, and when the user releases the pressing of the third button, the water getting signal is input to the refrigerator and is ended.

302: if the refrigerator obtains a water filling signal, the water filling valve port 412 is controlled to be opened.

The water filling means that the refrigerator fills water into the ice making device 300 through the self water supply device 400. The water filling signal is input through a sensor built in the refrigerator, and when the sensor detects that no ice cubes exist in the ice making cells, the water filling signal is input to a control system of the refrigerator, so that the water supply device 400 fills water into the ice making device 300.

303: if the refrigerator obtains the water taking signal and the water injection signal at the same time, the water taking valve port 413 is controlled to be opened, and after the water taking is finished, the water injection valve port 412 is controlled to be opened.

Because the water intaking signal carries out the input through the user, and the water injection signal is that the inside sensor of refrigerator carries out the input, the condition that water intaking signal and water injection signal coexisted takes place for being difficult to avoid, because water supply device 400's water inlet valve port 411 and domestic water pipe connection, water supply device 400 all relies on water pressure to realize for ice making device 300 water supply and supply the user's water intaking, if water injection process and water intaking process go on simultaneously, then can cause two way water pressure to reduce, lead to the water yield of injecting into to the ice cube tray in the water injection time of settlement and can not reach the water level requirement of making the ice-cube, lead to making the ice-cube incomplete, and the water yield of water intaking in-process output is less and unstable, influence user's water intaking experience.

In the control method for the refrigerator provided by this embodiment, when the refrigerator obtains the water taking signal and the water injection signal at the same time, the water taking valve port 413 is controlled to be opened first, and after the water taking by the user is finished, the water injection valve port 412 is controlled to be opened, so that the water injection process is performed independently in the water taking process, the reduction of water pressure is avoided, a large and stable water volume is obtained when the user takes water, and the water taking experience of the user is ensured; moreover, the water quantity injected into the ice cube tray within the set water injection time can reach the water level requirement required by the ice cube manufacturing, so that the integrity of the manufactured ice cube is ensured; moreover, the water taking valve 41 is opened firstly through control, namely the water taking process is carried out firstly, and then the water injection process is carried out, so that a user can obtain ice water immediately when taking water, the water injection is not required to be finished, and the use experience of the user is further improved.

304: if the refrigerator obtains a water intake signal during the water injection process, the water filling valve port 412 is controlled to be closed, the water intake valve port 413 is controlled to be opened, and after the water intake is finished, the water filling valve port 412 is opened.

Similarly, since the water intake signal is input by the user and the water injection signal is input by the sensor inside the refrigerator, the situation that the user needs to take water when the water supply device 400 is supplying water to the ice making device 300 inevitably occurs, and in order to avoid reducing the water pressure, in this situation, the control method of the embodiment closes the water injection valve port 412 by controlling the water intake valve port 413 to be opened, and opens the water injection valve port 412 after the water intake is finished, i.e. the water injection is stopped first, the user takes water preferentially, and the water injection to the ice making device 300 is continuously performed after the water intake is finished.

In this application embodiment, the refrigerator has a plurality of ice cube tray, and if the refrigerator received the signal to a plurality of ice cube tray water injection, control water injection valve mouth 412 carries out the water injection to a plurality of ice cube tray in proper order.

Similarly, the ice making cells are sequentially injected with water by controlling, namely the water injection process of each ice making cell is independent, the water pressure cannot be reduced, and the water injected into each ice making cell is ensured to reach the water level requirement required by the ice making cell.
