The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, the present invention relates to a washing machine, which comprises an inner tub 1 and a water collecting device 2, wherein the bottom of the inner tub 1 is provided with a drain hole 11, the side wall of the inner tub 1 is provided with a circle of dewatering holes only at the top, during dewatering, the inner tub rotates to drain the residual water in the inner tub 1 through the dewatering holes at the top, and the water flows into the water collecting device 2 and is discharged out of the machine body.
In the prior art, a valve plug is arranged at a drain hole, the valve plug is arranged on a water collecting device, the opening and closing of the drain hole are realized through up-and-down movement, and the valve plug is stopped at the drain hole in the washing process, so that the inner barrel can not rotate in the washing process. Therefore, the valve plug is arranged to limit the movement of the inner barrel, and the water sealing device is arranged at the water discharge hole 11 of the inner barrel and is in a normally closed state so as to ensure that the inner barrel can contain water and rotate when water enters for washing and provide power for washing.
As shown in fig. 2, fig. 2 is a partial enlarged view of a portion a in fig. 1, and the structure of a water sealing device and the like can be more clearly shown, and the water sealing device is a mechanical structure and can be pushed open by a push rod 4 arranged at the water collecting device 2.
As shown in fig. 2, the lower part of the top rod 4 is provided with a driving device capable of driving the top rod 4 to move up and down, when the inner barrel 1 needs to contain water, the top rod 4 is far away from the water sealing device to enable the water sealing device to be in a closed state, and when the water sealing device needs to be opened, the top rod 4 moves up to be capable of being stopped against the water sealing device.
The washing machine also comprises a water level detection device 6, wherein the water level detection device 6 is provided with an air chamber, the air chamber is communicated with the bottom of the water container, the water pressure in the water container compresses the gas in the air chamber, and the corresponding water level data is obtained by measuring the pressure of the gas in the air chamber.
The washing machine of the invention is also provided with a communicating pipeline 5, when the ejector rod 4 pushes the water sealing device open, the water in the inner barrel 1 can be communicated with a water level detection device 6 through the communicating pipeline 5, thereby realizing the detection of the water level in the inner barrel 1.
As shown in fig. 2, the push rod 4 is disposed inside the communication pipe 5, and when the push rod 4 pushes the water sealing device open, the water from the water discharge hole 11 can directly enter the communication pipe 5 and then communicate with the water level detecting device 6.
One end of the communication pipeline is communicated with the water level detection device 6, namely the communication air chamber, and the other end of the communication pipeline is an open opening and is used for surrounding the drain hole 11 after movement, so that water in the drain hole 11 flows out along the communication pipeline 5 and enters the water level detection device 6. The open type opening needs to surround the drain hole 11, so the arrangement position should correspond to the position of the drain hole 11, namely, the communication pipeline 5 is aligned with the position of the drain hole 11, after the water sealing cover 31 arranged at the drain hole 11 is opened, the communication pipeline 5 can seal and surround the drain hole 11, so that the water in the inner barrel 1 can not leak into the water collecting device 2, but flows into the communication pipeline 5 for detecting the water level.
Because the communicating pipeline 5 also moves up and down, under the sealing state of the water sealing device, the communicating pipeline 5 retracts and cannot influence the rotation of the inner barrel 1, the communicating pipeline 5 can be set to be a hard pipeline, so that the whole pipeline can move, a telescopic pipeline can be set at a position close to the drain hole 11, and the sealing and the separation of the drain hole 11 are realized by arranging the telescopic section 52. When the communication pipeline 5 moves upwards, the water drainage pipe can stop against the bottom of the inner barrel 1, and the position of the water drainage hole 11 is completely surrounded, so that the water in the inner barrel 1 only flows along the communication pipeline 5.
Because the ejector rod 4 and the communicating pipeline 5 need to move upwards when the water level needs to be detected, one end of the communicating pipeline 5 can be fixedly connected with the ejector rod 4 and integrally move, but due to different drainage arrangements, the communicating pipeline 5 and the ejector rod 4 can also be separately arranged and respectively driven, so that water in the inner barrel 1 can be drained into the water collecting device 2 after the ejector rod 4 is jacked open and sealed.
As shown in fig. 2, a water sealing ring 51 is further disposed at the opening of the communication pipeline 5, the water sealing ring 51 may be made of rubber, and the purpose of the water sealing ring 51 is to prevent water in the inner tub 1 from leaking out through the connection part and entering the water collecting device 2 when the communication pipeline 5 is communicated with the inner tub 1, thereby causing inaccurate water level detection result. Therefore, the water sealing ring 51 is arranged, so that when the communication pipeline 5 is stopped against the bottom of the inner barrel 1, a sealing structure is formed, water leakage can be guaranteed, and the accuracy of a detection result can also be guaranteed.
The diameter of the water seal ring 51 needs to be larger than that of the drain hole 11, and if the water seal ring 51 and the drain hole 11 are not circular, the water seal ring 51 needs to be sized to surround the drain hole 11 completely to obtain a sealing effect.
In addition, the time when the communication pipeline 5 is communicated with the water discharge hole 11 and the time when the ejector rod 4 is contacted and opened with the water sealing device have a certain time difference, namely the communication pipeline 5 is arranged in place, after the sealed environment is ensured, the ejector rod 4 is contacted with the water sealing device again to jack the water sealing device, so that the water in the inner barrel 1 enters the communication pipeline 5. Preferably, the position of the water sealing ring 51 is higher than the top of the top rod 4, so that the water sealing ring 51 contacts the inner barrel 1 first to form a sealing structure, and the top rod 4 can still move upwards to push the water sealing device after the water sealing ring 51 contacts the inner barrel 1 due to the contractibility of both rubber and pipelines.
The water sealing device comprises a water sealing cover 31, the top of the water sealing cover 31 is an arc spherical surface as shown in figure 2, so that the acting force of water on the water sealing cover is reduced when the ejector rod 4 is jacked up, the water sealing cover 31 is matched with the drain hole 11, and structures such as a sealing ring and the like are arranged to prevent water leakage.
As shown in fig. 2, the water sealing cover 31 extends from the lower end of the water sealing cover 31 to form a jack portion, which is a position matched with the push rod 4, besides the water sealing surface, the push rod 4 aligns with the jack portion to jack the whole water sealing cover 31, so that the water sealing cover 31 is separated from the inner barrel 1, and the water in the inner barrel 1 flows out from the water drainage hole 11.
The water sealing device is normally closed, so that a return spring 32 is further arranged, and when no external force such as the ejector rod 4 acts, the water sealing device is in a normally closed state under the action of the return spring 32, so that the bottom of the inner barrel 1 is ensured to be sealed.
The reset spring 32 is installed at the periphery of the jacking portion, one end of the reset spring 32 is abutted against the water sealing cover 31, and the other end of the reset spring is abutted against a fixed position and is limited in a cavity through a screw.
The bottom of the inner barrel is generally provided with a drainage hole which can be generally communicated with a water collecting device and is used for draining water in the inner barrel out of the machine body through the water collecting device. However, since the present invention provides the communication pipe 5 capable of communicating with the water level detecting device 6 at the water discharge hole 11 of the inner tub, the inner tub may be used in two embodiments for water discharge.
Example one
The drainage of the inner barrel is also drained through the communication pipeline.
The communication pipeline 5 is provided with a three-way structure at one end of the water level detection device 6, so that water in the communication pipeline 5 can flow into the water level detection device 6 to detect the water level and can flow into the drainage pipeline to drain water. The water level detection and drainage functions can be respectively realized by controlling the water level detection and drainage functions through the arrangement of the valve and other structures.
The drainage pipeline is provided with a drainage valve, and the functions can be realized through the on-off of the drainage valve.
As shown in fig. 3 and 4, fig. 3 shows a control method in which water level detection is required in the above-described installation, and fig. 4 shows a control method in which water discharge is required in the above-described installation.
Because the inner tub 1 of the washing machine can be configured to rotate during the washing process to realize dual power washing, the top rod 4 and the communication pipe 5 cannot contact with the inner tub 1 during the rotation of the inner tub 1 so as not to obstruct the rotation of the inner tub, and when the inner tub 1 stops rotating, the inner tub stops at a designated position which enables the water sealing device to be aligned with the top rod 4 and the communication pipe 5 for the purpose of opening and communication.
As shown in fig. 3, when the water level in the inner tub 1 needs to be detected, the communication pipe 5 is simultaneously communicated with the water level detecting device 6 and the drainage pipe, so that whether the drainage valve is closed needs to be judged, otherwise, the water in the inner tub 1 flows out along the drainage pipe, and the water level detection cannot be realized. When the drain valve is an opening device, the washing machine controls the drain valve to be closed and then carries out subsequent operation. When the drainage valve is in a closed state, the top rod 4 and the communication pipeline 5 move upwards (can move simultaneously or are driven respectively), the water sealing ring 51 on the communication pipeline 5 is abutted against the bottom of the inner barrel 1 to realize the sealing and surround of the drainage hole 11, after the sealing connection is formed, the top rod 4 continues to move upwards to push open the water sealing cover 31, at the moment, water in the inner barrel 1 can flow out from the drainage hole 11 and is communicated with the water level detection device 6 through the communication pipeline 5, the water pressure in the inner barrel 1 acts on gas in the air chamber, the water level in the inner barrel 1 is reacted through the air pressure in the air chamber, the water level detection device 6 feeds data back to the washing machine, and the water level detection process is completed.
In this embodiment, the driving devices of the rod 4 and the connecting pipe 5 can be driven separately to satisfy the operation of sealing the drain hole 11 and then pushing the water sealing device open.
When the inner barrel 1 needs to drain water, the drainage valve of the drainage pipeline needs to be ensured to be opened, the ejector rod 4 and the communication pipeline 5 move upwards, the water sealing ring 51 of the communication pipeline 5 and the inner barrel 1 are abutted to surround the drainage hole 11 to form sealing connection, then the ejector rod 4 jacks up the water sealing device, so that the inner barrel 1 is communicated with the water supply and drainage pipeline, and the water in the inner barrel is drained.
Above-mentioned setting up mode can be so that the drainage process, and the water in the interior bucket need not to get into water-collecting device, has avoided having in the water-collecting device to remain the washing water and breed the bacterium and be unfavorable for cleanly.
Example two
The ejector rod and the communication pipeline are respectively driven, and the water is still drained through the water collecting device.
The top rod 4 and the communication pipeline 5 have different functions respectively, the top rod 4 is used for jacking the water sealing device to realize the communication between the inner barrel 1 and the outside, and the communication pipeline 5 is used for surrounding the water discharge hole 11 to realize the communication between the inner barrel 1 and the water level detection device 6 to realize the water level detection. Therefore, the top rod 4 can be provided with a first driving device, the communication pipeline 5 is provided with a second driving device, the first driving device and the second driving device can be respectively driven, when the inner barrel 1 needs to be drained, only the top rod 4 is driven to push the water sealing device open, so that water in the inner barrel 1 flows into the water collecting device 2, the washing machine discharges the water in the water collecting device 2 to realize drainage, when the water level of the inner barrel 1 needs to be detected, the top rod 4 and the communication pipeline 5 are both driven, the communication pipeline 5 can be driven to realize sealing, and the top rod 4 is driven to open the water sealing device to enable the water in the inner barrel 1 to enter the water level detection device 6 through a closed flow channel.
Fig. 5 and 6 show the control method of the above arrangement, where fig. 5 shows the control method of the present embodiment requiring water level detection, and fig. 6 shows the control method of the present embodiment requiring water discharge.
As shown in fig. 5, when the inner tub 1 needs to detect the water level, the top rod 4 and the communication pipe 5 move upward, the water sealing ring 51 of the communication pipe 5 abuts against the bottom of the inner tub 1 and surrounds the water discharge hole 11 to form a sealing structure, the top rod 4 continues to move upward to open the water sealing cover 31, the inner tub 1 is communicated with the communication pipe 5, the water in the inner tub 1 flows into the water level detection device 6 through the communication pipe 5, the water level detection device 6 feeds back the water level data to the washing machine after detecting the water level data, and the detection is finished.
As shown in fig. 6, when the inner tub 1 needs to be drained, only the top rod 4 moves the top unsealing water cap 31 upward, at this time, the inner tub 1 is communicated with the water collecting device 2, and the washing water in the inner tub 1 enters the water collecting device 2 and is drained through the drainage pipeline provided in the water collecting device 2.
