By providing two limiting structures 500 and enabling the rotating handle 230 to be connected with the first limiting portions 510 of the two limiting structures 500, when the handle 230 is rotated, the two first limiting portions 510 can be driven to rotate between their respective first positions and second positions. Because the two limiting structures 500 are arranged along the extending direction of the rotating shaft 432 of the first limiting portion 510 and are respectively disposed at two opposite sides of the liquid storage box 200, when the liquid storage box 200 is pulled, the two opposite sides of the liquid storage box 200 are both pulled up, so that the liquid storage box 200 can be lifted up or put down more stably.

Illustratively, the turning handle 230 may include a first connection plate, a second connection plate, and a third connection plate. The first connection plate extends in a direction parallel to the rotation axis of the first limiting portion 510, the second connection plate is connected to one end of the first connection plate in the extending direction, the second connection plate is connected to the first limiting portion 510 in one of the two limiting structures 500, and the second connection plate is rotatably connected to the outer wall of the box 220.

The third connecting plate is connected to the other end of the first connecting plate in the extending direction, the third connecting plate is connected to the first limiting portion 510 in the other one of the two limiting structures 500, the third connecting plate is rotatably connected to the outer wall of the box 220, and the second connecting plate is parallel to the third connecting plate.

Through above-mentioned setting for first connecting plate, second connecting plate and third connecting plate form door frame type or "worker" style of calligraphy, and this shape is regular, the processing of being convenient for. When the user is operating, the first connecting plate can be held by hand to rotate, so that the second connecting plate and the third connecting plate are converted into vertical or inclined states, and then the first connecting plate is lifted upwards, and the liquid storage box 200 is driven to move through the second connecting plate and the third connecting plate.

Wherein, the first connecting plate, the second connecting plate and the third connecting plate can be an integrally formed structure, so that the overall structural strength of the rotary handle 230 can be increased.

Or the first connecting plate, the second connecting plate and the third connecting plate can also be of split structures, namely the first connecting plate, the second connecting plate and the third connecting plate are respectively processed, and then the three connecting plates are fixed together by utilizing the technologies of screw fastening or gluing and the like.

In addition, the turning handle 230 may have other shapes, such as a curved shape or an irregular shape, which is not particularly limited.

Of course, only one limit structure 500 may be provided, that is, the rotation handle 230 is connected to only the first limit portion 510 of the one limit structure 500.

On this basis, in order to adapt the rotation of the rotation handle 230 to the operation habit of the user, when the box 220 needs to be taken out from the slot 110, that is, when the first limiting portion 510 is at the second position, the extending direction of the first connecting plate and the extending direction of the second connecting plate are parallel to the extending direction of the slot 110, so that the user can hold the first connecting plate and pull up, thereby driving the box 220 to move outside the slot 110. So that it is suitable for the conventional pulling habit of the user.

When the box 220 needs to be clamped in the slot 110, i.e. the first limiting portion 510 is at the first position, the box 220 is first disposed in the slot 110, and then the first connecting plate is held and rotated, so that the extending direction of the second connecting plate and the extending direction of the third connecting plate are perpendicular to the extending direction of the slot 110. This prevents the turning knob 230 from taking up too much space in the extending direction of the tub 110.

In other embodiments, the first stop 510 may also be movable between a first position and a second position relative to the second stop 520. I.e., by the movement of the first stopper 510, the cartridge 200 is clamped or unclamped.

It can be appreciated that the first limiting portion 510 may move relative to the second limiting portion 520 in a linear direction, or may also move in a curved direction, as long as the first limiting portion 510 can be moved between the first position and the second position. The specific moving manner should be provided with the first limiting portion 510 and the second limiting portion 520 corresponding to the moving manner, for example, the second limiting portion 520 may be a protrusion, a groove, or the like. This is not listed here.

On this basis, in order to facilitate the communication between the second end of the pipe 300 and the liquid storage cavity, and in order to avoid the pipe 300 being exposed to the outside, as shown in fig. 10, the pipe 300 provided by the present application is disposed in the tank 110, for example, on the bottom of the tank 110, and is located between the liquid storage box 200 (not shown in fig. 10) and the fixing member 100.

Because the pipeline 300 is located in the tank 110 and between the liquid storage box 200 and the fixing member 100, the pipeline 300 can be prevented from being exposed to the outside, and the pipeline 300 can be better protected from being damaged.

Meanwhile, since the pipe 300 is located in the tank 110 and the liquid storage box 200 is at least partially located in the tank 110, the pipe 300 is very close to the liquid storage box 200, so that the second end of the pipe 300 can be more conveniently communicated with the liquid storage cavity.

In this case, in order to improve the stability of the fixing of the pipe 300, the pipe 300 may be fixed in the tank 110, so that the pipe 300 may be stably fixed in the tank 110, preventing movement thereof, thereby ensuring that the detergent can stably move in the pipe 300 when the detergent is added, and thus ensuring that the detergent is stably added into the cavity.

On this basis, in order to allow the first end of the pipe 300 to communicate with the cavity, a through hole may be formed in the fixing member 100 such that one end of the through hole communicates with the first end of the pipe 300 and the other end of the through hole communicates with the cavity, thus allowing the detergent to enter the cavity through the pipe 300.

Alternatively, as shown in fig. 11, a flow passage 210 may be provided in the washing chamber along the extending direction of the tub 110 such that the flow passage 210 penetrates the detergent box such that one end of the flow passage 210 communicates with the first end of the duct 300 such that the other end of the flow passage 210 communicates with the chamber. This allows detergent to enter the cavity through the pipe 300, the flow passage 210.

Of course, the pipe 300 may be disposed outside the tank 110.

On this basis, in order to realize the communication between the second end of the pipe 300 and the liquid storage chamber, as shown in fig. 12, a groove 240 is formed on the outer wall of the liquid storage box 200, as shown in fig. 13, a channel 250 is opened on the side wall of the groove 240, a first end of the channel 250 is communicated with the groove 240, a second end of the channel 250 is communicated with the liquid storage chamber (space on the right side of the channel 250 in fig. 13), and the second end of the pipe 300 can move between a third position and a fourth position along the groove depth direction of the groove 240.

As shown in fig. 13, the automatic adding assembly 10 includes an elastic member 600 and a sealing member 700. The elastic member 600 is disposed in the groove 240, and one end of the elastic member 600 is connected with the inner wall of the groove 240; the sealing member 700 is sealingly disposed in the groove 240, and the other end of the elastic member 600 is connected to the sealing member 700.

In the third position, as shown in fig. 14, the second end of the tube 300 extends into the groove 240 and abuts the seal 700, the first end of the channel 250 communicates with the second end of the tube 300, and the resilient member 600 is in an elastically deformed state.

In the fourth position, as shown in fig. 15, the seal 700 is moved by the resilient member 600 to isolate the first end of the passage 250 from the second end of the pipe 300.

Through the above arrangement, when the liquid storage box 200 containing the detergent is required to be communicated with the second end of the pipeline 300, the pipeline 300 is moved, so that the second end of the pipeline 300 stretches into the groove 240 and contacts with the sealing member 700 to drive the sealing member 700 to move, so that the sealing member 700 avoids the first end of the channel 250, and meanwhile, the first end of the channel 250 is communicated with the second end of the pipeline 300, so that the liquid storage cavity is communicated with the second end of the pipeline 300 through the channel 250, and the detergent can enter the pipeline 300, thereby ensuring the normal implementation of the automatic detergent adding function of the dish washer.

When less detergent is needed to be added in the liquid storage box 200, the pipe 300 is pulled out, and the sealing member 700 cuts off the first end of the channel 250 and the second end of the pipe 300 under the action of the elastic member 600, so that when the channel 250 is located at the bottom of the liquid storage box 200, the residual liquid in the liquid storage cavity can be prevented from leaking to the outside through the channel 250.

It will be appreciated that when the cartridge 200 includes the rotatable handle 230 and the housing 220, the recess 240 should be formed in the housing 220.

It can be appreciated that, when the pipe 300 is pulled out of the groove 240, in order to ensure that the sealing member 700 can be quickly moved by the elastic member 600 to separate the first end of the channel 250 from the second end of the pipe 300, the elastic member 600 should have a proper elasticity, so that the elastic member 600 is ensured to be properly elastically deformed under the action of force, and the sealing member 700 can be quickly moved.

The elastic member 600 may include a spring, may include a rubber rod, or may be any other suitable elastic body.

When the elastic member 600 includes a spring, in order to stably fix the spring on the sealing member 700, a fixing column may be disposed on the sealing member 700, so that the spring is partially sleeved on the fixing column, and thus the fixing column may provide support for the spring, and prevent the spring from moving in a large range in other directions except in a groove depth direction along the groove 240 when the spring is elastically deformed, thereby ensuring stability of fixing the spring.

In addition, the elastic member 600 may be disposed between the sealing member 700 and the bottom of the groove 240, so that when the second end of the pipe 300 extends into the groove 240 and abuts against the sealing member 700, the sealing member 700 may drive the elastic member 600 to compress and deform.

Alternatively, the elastic member 600 may be disposed between the sealing member 700 and the sidewall of the groove 240, so that when the second end of the pipe 300 extends into the groove 240 and abuts against the sealing member 700, the sealing member 700 drives the elastic member 600 to stretch and deform.

In some embodiments, as shown in fig. 16, the sealing member 700 includes a moving block 710 and a first sealing ring 720, the first sealing ring 720 is sleeved on the moving block 710, and the first sealing ring 720 is sealed between the moving block 710 and an inner wall of the groove 240, so that a second end of the pipe 300 can abut against the moving block 710, and the elastic member 600 is fixedly connected with the moving block 710.

By the above arrangement, the first sealing ring 720 has a sealing effect, and leakage of the detergent can be prevented. The moving block 710 may be made of a hard material, so that the elastic member 600 can be easily fixed. The sealing and fixing of the elastic member 600 is achieved by the cooperation of the first sealing ring 720 and the moving block 710.

On this basis, in order to increase the stability of the seal between the pipe 300 and the side wall of the groove 240, as shown in fig. 17, the automatic adding assembly 10 further includes a sealing body 800, a sealing groove 251 is formed on the outer wall of the pipe 300, and in the case of the third position, the sealing groove 251 is located in the groove 240, and the sealing body 800 is disposed in the sealing groove 251 and sealed between the pipe 300 and the inner wall of the groove 240.

By providing the sealing body 800 between the pipe 300 and the inner wall of the groove 240, the gap between the pipe 300 and the inner wall of the groove 240 is sealed by the sealing body 800, thereby preventing the detergent from oozing out from between the pipe 300 and the inner wall of the groove 240.

The seal groove 251 may or may not be an annular groove surrounding the circumference of the pipe 300.

In addition, when the seal groove 251 is an annular groove, the sealing body 800 may include a second seal ring, which is disposed in the annular groove, so that the second seal ring may provide sealing for the inner wall of the groove 240 and the pipe 300 everywhere in the circumferential direction of the pipe 300, so that the sealing effect is better.

Alternatively, seal body 800 may include a plurality of sealing blocks that fill seal groove 251 to provide a seal between conduit 300 and the inner wall of groove 240.

In order to drive the detergent to flow in the pipe 300 using the driving device 400, as shown in fig. 18, the pipe 300 includes an elastic tube 310. The driving device 400 includes a rotating disc 410, a pressing member 420 and a driving member 430, wherein the elastic tube 310 extends at least partially along the circumferential direction of the rotating disc 410, and the rotating disc 410 rotates relative to the elastic tube 310; the pressing member 420 is connected to one side of the rotating disc 410, and the pressing member 420 abuts against the outer wall of the elastic tube 310 for pressing the liquid in the pipe 300 from the first end of the pipe 300 to the second end of the pipe 300; the driving member 430 is used to drive the rotation disk 410 to rotate.

Through the above arrangement, the driving member 430 is utilized to drive the rotating disc 410 to rotate, and then the extrusion member 420 is driven to rotate, and as the extrusion member 420 is abutted against the outer wall of the elastic tube 310, the elastic tube 310 is extruded in the process of the movement of the extrusion member 420, so that the detergent in the elastic tube 310 is extruded into the cavity, and the automatic addition of the detergent is realized.

It can be appreciated that in order to prevent the detergent in the storage chamber from entering the chamber when the detergent is not required to be added, the pressing member 420 should be abutted against the outer wall of the elastic tube 310 and the flow of the detergent in the elastic tube 310 should be blocked when the driving member 430 stops operating, i.e., the rotating disc 410 does not rotate.

As shown in fig. 19, a plurality of pressing members 420 may be provided, and a plurality of pressing members 420 may be spaced apart around the rotation axis 432 of the rotation disk 410. The elastic tube 310 is compressed by the plurality of pressers 420, so that the liquid in the liquid storage cavity can quickly enter the cavity, and the speed of adding the detergent is increased.

In addition, the rotating disk 410 may be provided as a circular disk, and the plurality of pressing members 420 may be uniformly disposed around the rotation axis 432 of the rotating disk 410, so that the rotation speed of the rotating disk 410 may be controlled by controlling the driving member 430, thereby controlling the amount of detergent entering the cavity.

Alternatively, only one extrusion 420 may be provided.

On the basis, as shown in fig. 20, the extrusion piece 420 comprises a support column 421 and a rolling piece 422, wherein the support column 421 is connected to one side of the rotating disc 410, and an included angle A is formed between the axial direction of the support column 421 and the plane of the rotating disc 410, and the included angle A is more than 0 degrees and less than or equal to 90 degrees; the rolling element 422 is sleeved on the supporting column 421 and is abutted with the outer wall of the elastic tube 310, and the rolling element 422 can rotate around the supporting column 421.

In this way, since the rolling member 422 can rotate around the supporting column 421, the rotation of the rolling member 422 can reduce the friction between the rolling member 422 and the outer wall of the elastic tube 310 during the pressing of the elastic tube 310 by the rolling member 422, thereby reducing the abrasion of the elastic tube 310. The service life of the elastic tube 310 is improved.

In order to stably set the rolling element 422 on the supporting column 421, a clamping groove may be formed on a side wall of the supporting column 421, a through hole is formed on the rolling element 422, the rolling element 422 is sleeved on the supporting column 421 through the through hole, and a part of the rolling element 422 extends into the clamping groove, so that the rolling element 422 is abutted to the elastic tube 310, and friction force between the rolling element 422 and the elastic tube 310 drives the rolling element 422 to rotate along with the rotation of the rotating disc 410. Due to the limiting effect of the clamping groove, the rolling element 422 can stably rotate on the supporting column 421.

Alternatively, as shown in fig. 21, the driving device 400 further includes a cover plate 440, and the cover plate 440 is disposed on a side of the pressing member 420 away from the rotating disc 410, so that the support column 421 is fixedly connected with the rotating disc 410. The rolling member 422 is restrained therebetween by the rotating disk 410 and the cover plate 440 to ensure stable rotation of the rolling member 422.

Of course, the extrusion 420 may also include only the support posts 421, i.e., the support posts 421 abut the outer wall of the elastomeric tube 310.

In order to drive the rotating disc 410 to rotate by using the driving member 430, as shown in fig. 22, the driving member 430 includes a first gear 431, a rotation shaft 432, a second gear 433, and a power member 434, the first gear 431 is sequentially disposed with the rotating disc 410 along the rotation shaft 432 direction of the rotating disc 410, and the central axis of the first gear 431 coincides with the rotation shaft 432 of the rotating disc 410; one end of the rotation shaft 432 is connected to the first gear 431, the other end of the rotation shaft 432 is connected to the rotation disc 410, and the axis of the rotation shaft 432 coincides with the rotation shaft 432 of the rotation disc 410; the second gear 433 is in transmission connection with the first gear 431; the power member 434 is coupled to the second gear 433 for driving the second gear 433 to rotate.

Through the above arrangement, the power member 434 may drive the second gear 433 to rotate, and since the second gear 433 is in transmission connection with the first gear 431, the second gear 433 may drive the first gear 431 to rotate, and since the first gear 431 is connected with the rotating disc 410 through the rotating shaft 432, the rotation of the first gear 431 may drive the rotating disc 410 to rotate. The rotating disc 410 is driven to rotate by gear transmission, and the gear transmission is stable and reliable.

It can be understood that the power element 434 drives the second gear 433 to rotate means that the output shaft of the power element 434 coincides with the rotation axis 432 of the second gear 433, so that the output shaft of the power element 434 can drive the second gear 433 to rotate when rotating.

The first gear 431 and the second gear 433 are in transmission connection, and the first gear 431 may be directly meshed with the second gear 433 to perform transmission.

Alternatively, as shown in fig. 22, at least one third gear may be disposed between the first gear 431 and the second gear 433, where the third gear is meshed with the first gear 431 and is meshed with the second gear 433, and the third gear is used as a transmission member, so that the main power on the second gear 433 is transmitted to the first gear 431 and then to the rotating disc 410, so as to drive the rotating disc 410 to rotate.

In addition, the power member 434 may include an electric motor, or may also include a motor.

Illustratively, the driving member 430 may also include a connecting shaft, a power member 434, and a belt, wherein the connecting shaft is connected to the rotating disc 410, and the axis of the connecting shaft coincides with the rotational axis 432 of the rotating disc 410; a belt drive is connected between the connecting shaft and the output shaft of the power member 434.

Through the above arrangement, the belt is driven to rotate by the power member 434, so that the connecting shaft is driven to rotate, and the rotating disc 410 is driven to rotate, so that the liquid in the elastic tube 310 is driven to flow.

Illustratively, the driving member 430 may also include a push rod motor and a crankshaft, one end of which is connected to a side of the rotating disc 410, and the other end of which is connected to an output shaft of the push rod motor. The movement of the output shaft of the push rod motor drives the crankshaft to move, and thus drives the rotating disc 410 to rotate, thereby driving the liquid in the elastic tube 310 to flow.

In other embodiments, the driving device 400 may also include a solenoid pump, where the solenoid pump is connected to the pipe 300, and the solenoid pump is directly used to pump the detergent in the liquid storage chamber into the chamber.

In this case, a flow rate monitoring device may be provided on the pipe, and the flow rate in the pipe 300 is detected using the flow rate monitoring device, thereby controlling the amount of detergent added to the chamber.

The volume of the reservoir is limited and for detecting the amount of detergent in the reservoir, the automatic adding assembly 10 further includes a liquid level detecting device 900 for detecting the liquid level in the reservoir 200, as shown in fig. 23.

By arranging the liquid level detection device 900 to detect the liquid level of the liquid in the liquid storage cavity, the too small amount of the detergent in the liquid storage cavity is avoided, and therefore normal addition of the detergent can be ensured each time.

In order to facilitate reminding a user, the detection result of the liquid level detection device 900 may be displayed on a display screen of the dishwasher, so as to remind the user.

Or, can also install the warning light on dish washer, the liquid volume in the stock solution intracavity reduces at a certain amount, and the warning light can start, and the suggestion user needs to add the detergent.

Illustratively, as shown in FIG. 24, the fluid level detection apparatus 900 includes a magnetic float 910 and a magnetic switch 920. The magnetic floater 910 is disposed in the liquid storage cavity, the magnetic switch 920 is disposed on the fixing member 100, and the magnetic floater 910 and the magnetic switch 920 are sequentially arranged along the descending direction of the liquid in the liquid storage cavity.

In this way, when the liquid level of the detergent in the liquid storage cavity drops to a certain level, the magnetic floater 910 is close to the magnetic switch 920, so that the magnetic switch 920 is turned off or turned on, and then information is sent to the controller of the dishwasher, so that the information of the lack of the liquid in the liquid storage cavity is displayed on the display panel, and a user is prompted to supplement the detergent in the liquid storage cavity.

Wherein, the magnetic switch 920 may be composed of a reed switch.

The foregoing is merely illustrative of specific embodiments of the present application, and the scope of the present application is not limited thereto, but any changes or substitutions within the technical scope of the present application should be covered by the scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
