Description

Technical Field

[0001] The utility model belongs to the technical field of washing machines, and in particular relates to a washing machine drain valve and a washing machine with the same. Background Art

[0002] As a common device for washing clothes, washing machines are widely used in people's daily lives. At present, when washing clothes, washing machines realize water inlet and water discharge functions through electric control.

[0003] As people's requirements for quality of life and comfort of life are also increasing, washing machines are an important part of people's lives. While meeting the needs of washing, washing machines must also be able to better protect clothes. Washing machines with circulating water flow function can fully dissolve detergents and flush clothes. The water flow not only improves washing, but also has the effect of dispersing clothes and reducing clothing entanglement. Washing machines with circulating water flow function rotate the water-dispensing ribs at the bottom of the barrel to continuously pump water from the inner barrel to between the water tub and the inner barrel, so that the water level between the water tub and the inner barrel rises, and the rising water flows through the barrel cover and flows into the inner barrel to form a circulating water flow. In conventional washing machines, the dehydration state of the clutch and the opening state of the water tub drain port are linked. When the clutch of a conventional washing machine is in the dehydration state, the drain port of the water tub is in the open state. When the washing machine with circulating water flow function is in the circulating water flow operation, when the clutch is in the dehydration state, the drain port of the water tub needs to remain sealed. Therefore, for washing machines with circulating water flow function, it is generally necessary to set a motor that controls the opening and closing of the drain separately to control the clutch and the drain port separately.

[0004] However, in the prior art, the clutch is generally controlled by a traction device pulling the brake arm of the clutch through a traction rod. The bottom space of the washing machine is limited. If a separately controlled motor is installed at the bottom of the washing machine, the space available for the components at the bottom of the washing machine will be reduced during installation, which may cause interference between the components at the bottom of the washing machine, thereby affecting the reliability of the washing machine. Utility Model Content

[0005] In view of this, the utility model provides a washing machine drain valve and a washing machine having the same, which can solve the problem that when a separately controlled drain valve motor is added to the bottom of the washing machine, due to limited space, components at the bottom of the washing machine may interfere with each other.

[0006] In order to solve the above problems, the utility model mainly provides the following technical solutions:

[0007] On the one hand, the utility model provides a washing machine drain valve, which includes a water inlet pipe, a motor valve plug mounting pipe and a drain pipe, wherein the water inlet pipe, the motor valve plug mounting pipe and the drain pipe are connected to form a three-way valve, and an overflow pipe is opened on the side wall of the drain pipe to the outside;

[0008] The axis of the water inlet pipe is coplanar with the axis of the motor valve plug mounting pipe; the axis of the water inlet pipe, the axis of the overflow pipe and the axis of the drain pipe are coplanar;

[0009] With the cross section of the drain pipe as the projection plane, there is an angle between the axis of the motor valve plug mounting pipe and the axis of the overflow pipe.

[0010] In some embodiments, the angle is no greater than 30°.

[0011] In some embodiments, the axis of the motor valve plug mounting tube is skewed and perpendicular to the axis of the drain pipe, and / or the axis of the overflow pipe is perpendicular to the axis of the drain pipe.

[0012] In some embodiments, the axis of the water inlet pipe is perpendicular to the axis of the motor valve plug mounting tube.

[0013] In some embodiments, a drain valve motor is also included. The drain valve motor is connected to an end of the motor valve plug mounting tube away from the water inlet pipe, and the drain valve motor is used to control the switch of the water inlet.

[0014] In some embodiments, the water inlet pipe, the motor valve plug mounting pipe and the drain pipe are integrally formed.

[0015] In some embodiments, a connecting piece is further included, the connecting piece is connected to the outer side wall of the motor valve plug mounting tube, and the connecting piece includes a mounting through hole.

[0016] In some embodiments, the connector is integrally formed with the motor valve plug mounting tube.

[0017] On the other hand, the utility model further provides a washing machine, which includes the above-mentioned washing machine drain valve.

[0018] In some embodiments, a mounting hole group is provided at the bottom of the washing machine at the position of the drain port, and the mounting hole group is used to install a drain valve of the washing machine.

[0019] Compared with the prior art, the washing machine drain valve and the washing machine having the same provided by the utility model have at least the following beneficial effects:

[0020] In the technical solution provided by the utility model, the utility model provides a washing machine drain valve, which includes a water inlet pipe, a motor valve plug mounting pipe and a drain pipe. The water inlet pipe, the motor valve plug mounting pipe and the drain pipe are connected to form a three-way valve, and the side wall of the drain pipe is opened outwardly with an overflow pipe; the axis of the water inlet pipe is coplanar with the axis of the motor valve plug mounting pipe; the axis of the water inlet pipe, the axis of the overflow pipe and the axis of the drain pipe are coplanar; with the cross section of the drain pipe as the projection surface, there is an angle between the axis of the motor valve plug mounting pipe and the axis of the overflow pipe. Based on this, the utility model designs the washing machine drain valve, and in order to make the space arrangement at the bottom of the washing machine more compact and non-interfering after installation, the drain valve plug mounting pipe is rotated by a certain angle so that the drain valve motor can give way to the clutch, traction device, etc. after the drain valve plug mounting pipe is connected to the drain valve motor, so that the position arrangement of each component is reliable. The utility model avoids the problem that the various components at the bottom of the washing machine are partially installed too compactly, which may cause unnecessary interference between the various components due to vibration, shaking, etc. when the washing machine is in operation. By adopting the washing machine drain valve of the utility model, the position of the original washing machine components can be kept basically unchanged, and the influence of the installation of the drain valve motor on other components can be avoided to a certain extent, thereby achieving the flexibility of the installation of the various components at the bottom of the washing machine and improving the reliability of the washing machine.

[0021] In some embodiments, the angle is no greater than 30°. The utility model limits the rotation angle of the drain valve plug mounting tube to avoid the possibility that the drain valve motor connected to the drain valve plug mounting tube and the clutch of the washing machine may be affected by the rotation angle on one side, or the drain valve plug mounting tube may be leaked out of the outer periphery of the bottom of the washing machine by the rotation angle on the other side, thereby adversely affecting the overall component layout of the bottom of the washing machine. Therefore, the utility model further improves the reliability of the installation of the bottom components of the washing machine through this angle design.

[0022] In some embodiments, the axis of the motor valve plug mounting pipe of the utility model is skewed and perpendicular to the axis of the drain pipe, and / or the axis of the overflow pipe is perpendicular to the axis of the drain pipe. The utility model considers the compatibility of the drain valve and the washing machine installation, and after the drain valve plug mounting pipe rotates a certain angle, the other pipe openings still maintain the original position relationship, and then after the washing machine drain valve of the utility model is installed on the washing machine, the position change of the connection between the washing machine drain valve and other components or pipelines can be avoided to a certain extent. Through the above design, the utility model improves the reliability of the washing machine while ensuring that the original connection position of the washing machine remains basically unchanged.

[0023] In some embodiments, the utility model further comprises a drain valve motor, which is connected to an end of the motor valve plug mounting tube away from the water inlet pipe, and the drain valve motor is used to control the switch of the water inlet. The utility model connects the drain valve motor to the motor valve plug mounting tube, and the drain valve motor controls the switch of the water inlet pipe by relying on the valve plug. When applied to a washing machine with a circulating water flow, the washing machine controls the traction device 8 to pull the brake arm of the clutch 7 to release the brake disc. At the same time, the drain valve motor controls the water inlet to close. The above two controls are provided so that the washing machine can enter the circulating water cleaning state.

[0024] In some embodiments, the water inlet pipe, the motor valve plug mounting pipe and the drain pipe of the utility model are integrally formed. The utility model avoids the problem that the connection of the integral components is easily damaged due to the connection design to a certain extent by designing the water inlet pipe, the motor valve plug mounting pipe and the drain pipe as an integrally formed one, and effectively improves the reliability of the washing machine drain valve of the utility model.

[0025] In some embodiments, the utility model further includes a connector, which is connected to the outer side wall of the motor valve plug mounting tube, and the connector includes a mounting hole. The utility model washing machine drain valve has a connector, and the connector has a mounting hole. The main function of the connector is to stably mount the washing machine drain valve on the washing machine, thereby improving the reliability of the installation of the washing machine components.

[0026] On the other hand, the utility model further provides a washing machine, which includes the above-mentioned washing machine drain valve. The bottom of the washing machine is provided with a mounting hole group at the position of the drain port, and the mounting hole group is used to install the washing machine drain valve. The washing machine is processed with an adaptive mounting hole group for the washing machine drain valve of the utility model, and combined with the structural design of the washing machine drain valve of the utility model, under the premise of ensuring that the original connection position remains basically unchanged, the reasonable arrangement of the bottom components of the washing machine can be effectively realized, and mutual interference between the components can be avoided, thereby improving the reliability and stability of the washing machine.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0040] The utility model provides a washing machine drain valve, which comprises a water inlet pipe 1, a motor valve plug mounting pipe 2 and a drain pipe 3. The water inlet pipe 1, the motor valve plug mounting pipe 2 and the drain pipe 3 are connected to form a three-way valve, and an overflow pipe 5 is opened on the side wall of the drain pipe 3 to the outside; the axis of the water inlet pipe 1 is coplanar with the axis of the motor valve plug mounting pipe 2; the axis of the water inlet pipe 1, the axis of the overflow pipe 5 and the axis of the drain pipe 3 are coplanar; with the cross section of the drain pipe 3 as a projection plane, an angle is formed between the axis of the motor valve plug mounting pipe 2 and the axis of the overflow pipe 5.

[0041] In some embodiments, Figure 1 and Figure 4 As shown, the pipeline of the washing machine drain valve of the utility model comprises a water inlet pipe 1, a motor valve plug mounting pipe 2, a drain pipe 3 and an overflow pipe 5, and a connector 4 is mounted on the motor valve plug mounting pipe 2. When the valve plug is not closed, the water inlet pipe 1, the motor valve plug mounting pipe 2, the drain pipe 3 and the overflow pipe 5 can form a pipe passage. In the prior art, the axes of the water inlet pipe 1, the motor valve plug mounting tube 2, the drain pipe 3 and the overflow pipe 5 are designed to be in the same plane. The utility model keeps the water inlet pipe 1, the drain pipe 3 and the overflow pipe 5 unchanged, and rotates the motor valve plug mounting tube 2 around the axis of the water inlet by a certain angle through structural design according to actual working conditions, while the water inlet pipe 1, the drain pipe 3 and the overflow pipe 5 still maintain the same plane. In this way, after the drain valve of the washing machine of the utility model is installed on the washing machine, the motor valve plug mounting tube 2 forms a certain angle with the plane of the water inlet pipe 1, the drain pipe 3 and the overflow pipe 5 after rotation, so that the drain valve motor 7 connected to the motor valve plug mounting tube 2 can make way for other components at the bottom of the washing machine, such as (clutch 11, traction device 12, etc.), to avoid cross-installation of various components at the bottom of the washing machine and improve the stability of the washing machine during operation. Moreover, the utility model can flexibly design the rotation angle of the motor valve plug mounting tube 2 as needed, so that the position arrangement of various components at the bottom of the washing machine is relatively reasonable, the spatial arrangement of various components is more compact, and the degree of mutual interference is reduced, thereby improving the reliability of the washing machine as a whole.

[0042] In some embodiments, the utility model controls the angle between the axis of the motor valve plug mounting tube 2 and the axis of the overflow pipe 5 to be no more than 30° based on the actual structural considerations of the washing machine. The purpose of designing this angle is to enable the motor valve plug mounting tube 2 to be connected to the drain valve motor 7, and the drain valve motor 7 to avoid the clutch 11 and the tractor 12 along two opposite angles, and on this basis, it is necessary to ensure that the drain valve motor 7 does not interfere with or contact the clutch 11, and to ensure that the drain valve motor 7 does not leak out of the bottom of the washing machine. The specific angle design is of course not limited to the above angles, and can be determined according to the overall structure of the washing machine, the structure and size of the components, and the installation position. The purpose is to maintain the stability of the washing machine and the role of giving way. In this way, by controlling the structural design of the washing machine drain valve of the utility model, the avoidance effect of the washing machine drain valve of the utility model after installation is improved while ensuring that the washing machine itself maintains its original structure, thereby improving the stability and reliability of the washing machine.

[0043] In some embodiments, the axis of the motor valve plug mounting pipe 2 of the utility model is perpendicular to the axis of the drain pipe 3, and / or the axis of the overflow pipe 5 of the utility model is perpendicular to the axis of the drain pipe 3. Figure 1 and Figure 6As shown, after the motor valve plug installation tube 2 is rotated, the utility model is set so that the axis of the overflow pipe 5 remains perpendicular to the axis of the drain pipe 3, and the connection position with the overflow pipe 6 of the original washing machine can be maintained, thereby maintaining the original installation method of the washing machine for the two pipes, avoiding the problem of affecting the stability of the washing machine due to changes in the pipeline or position. The utility model is designed so that the axis of the motor valve plug installation tube 2 and the axis of the drain pipe 3 are skewed and perpendicular, so that the drain pipe 3 can adapt to the discharge pipe in the vertical direction of the washing machine (the discharge pipe is connected to the drain pipe 3), further maintaining the original installation method of the washing machine for the drain pipe, and maintaining the stability of the washing machine. On this basis, the axis of the water inlet pipe 1 of the utility model is perpendicular to the axis of the motor valve plug installation tube 2, which is also to ensure that the utility model washing machine drain valve can adapt to the overall structure of the washing machine after being installed on the washing machine, and will not cause the position of other components of the washing machine to change and affect the stability of the washing machine. In the actual design, as a preferred embodiment, in the actual working conditions, the connection between the axis of the water inlet pipe 1 and the motor valve plug mounting pipe 2 can be designed as an arc-shaped elbow to improve the smoothness of the water flow through this part. It should be noted that when modifying the structure, it is generally necessary to maintain the unnecessary improved structure and connection relationship, because the power of the washing machine in the working stage, such as water inlet, drainage and rotation, is relatively large, and it is necessary to design the angles and lengths of the overall accessories, connecting pipes, etc., so as to ensure the stability of the washing machine during operation. After adjustment, the washing machine has its own stable structure. On this basis, after we change a part of the structure, we need to try to maintain the original connection angle and position of the pipe, etc., so as to reduce the adverse effects on the overall washing machine caused by the change of the angle position of other structural components. Therefore, the utility model proposes the above-mentioned washing machine drain valve, which improves the stability of the washing machine while avoiding the bottom components of the washing machine to reduce the interference between the bottom components.

[0044] In some embodiments, Figure 4 As shown, the motor valve plug mounting pipe 2 of the utility model is connected to the drain valve motor 7. The drain valve motor 7 of the utility model can independently control the drainage function of the washing machine drain valve of the utility model, so that the washing machine drain valve can be applied to washing machines with circulating water function.

[0045] As an example, Figure 4 and Figure 6As shown, after the drain valve of the washing machine of the utility model is installed on the washing machine with the function of circulating water, the operating principle of the washing machine is as follows: on the basis of the structure of the washing machine, the drain valve motor 7 which is controlled separately is connected to the motor valve plug mounting pipe 2 of the drain valve of the washing machine, and the switching of different washing modes of the washing machine is controlled by the coordinated control of the drain valve motor 7 and the tractor 12. Compared with the motor configured for the drain valve of the prior art, the drain valve motor 7 of the utility model is located at a farther end of the tractor 12 and the clutch 11, so that the movement area of ​​the tractor 12 and the clutch 11 can be effectively avoided during the operation of the washing machine. Because the tractor 12 has a traction rod 14 and the clutch 11 has a brake arm 13, the movement trajectory of the connection part between the two is an arc, which will occupy more space at the bottom of the washing machine. Therefore, the utility model, through the design of the drain valve of the washing machine, enables the drain valve motor 7 connected thereto to give way to the tractor 12 and the clutch 11, thereby improving the problem of reduced reliability of the washing machine caused by the mutual influence between the tractor 12 and the clutch 11 and the drain valve motor 7.

[0046] As an example, Figure 4 and Figure 6 As shown, the utility model washing machine drain valve is installed after the washing machine with circulating water function. When the washing machine is in the normal washing mode, the drain valve motor 7 and the tractor 12 are both in standby state, the pipe of the drain valve is sealed by the valve plug and the brake disc of the clutch 11 is locked. When the washing machine is in the circulating water washing state, the tractor 12 pulls the brake arm 13 of the clutch 11 through the traction rod 14 to release the brake disc, and the inner drum and the impeller (not shown in the figure) synchronously move at high speed to drive the washing water level to rotate along the outer drum 9 to the outer drum cover 10, and the outer drum cover 10 blocks the water flow and sprays downward, and the washing water is combined with the rotation of the inner drum and the impeller to realize circulating water cleaning in the outer drum 2. When the washing machine is in the drainage state, the tractor 12 is in standby state, and the drain valve motor 7 works to open the valve plug and drain pipe 2 to open the washing water through the drain pipe 3. When the washing machine is in the dehydration state, the traction device 12 pulls the brake arm 13 of the clutch 11 to release the brake disc, and the drain valve motor 7 works to open the valve plug so that the drain pipe 3 is opened. The inner drum and the impeller (not shown in the figure) move synchronously at high speed to spin dry the clothes, and the dried water is discharged through the drain pipe 3, thereby realizing the dehydration operation of the washing machine.

[0047] In some embodiments, Figure 1As shown, the water inlet pipe 1, the motor valve plug mounting tube 2, and the drain pipe 3 are integrally formed. The purpose of its design is mainly to ensure the sealing and stability of the washing machine drain valve of the utility model. The angle and position can be designed before processing, and the leakage problem that may be caused by the connection part can be avoided to a certain extent through integral processing. On this basis, the connector 4 of the utility model is connected to the outer wall of the motor valve plug mounting tube 2, and the connector 4 includes two mounting through holes 41. The connector 4 can be selected to have a trapezoidal structure to improve stability, and the upper bottom part of the trapezoidal structure is matched with the outer wall of the motor valve plug mounting tube 2 or integrally formed. The utility model fixes the washing machine drain valve to the bottom of the washing machine by designing the connector 4. The mounting through hole 41 corresponds to the mounting hole group at the bottom of the washing machine. Thereby achieving the stable installation of the washing machine drain valve of the utility model.

[0048] The utility model also provides a washing machine, which includes the above-mentioned washing machine drain valve. The washing machine is a washing machine with a circulating water flow function, which has an inner drum and an outer drum 9, an outer drum cover 10, an overflow port 8, and an overflow pipe 6. The washing machine drain valve of the utility model is arranged at the bottom of the washing machine, the water inlet pipe 1 of the washing machine drain valve is connected to the drain port at the bottom of the washing machine, the overflow pipe 5 is connected to the overflow pipe 6, the motor valve plug mounting pipe 2 is installed with a drain valve motor 7, the drain pipe 3 is connected to the drain pipe, and the overflow pipe 5 is directly connected to the drain pipe 3, which is not controlled by the drain valve motor 7. After the washing machine of the utility model is installed with the washing machine drain valve, the structure of the bottom thereof is compact, the arrangement of each component is reasonable, the mutual interference degree is small, and it has better stability.

[0049] like Figure 5 As shown, the bottom of the washing machine is provided with a mounting hole group at the position of the drain port, and the mounting hole group is used to install the washing machine drain valve. The mounting hole group of the utility model includes two first mounting holes 15, and the two first mounting holes 15 correspond to the two mounting through holes 41. It should be noted that the opening positions of the two first mounting holes 15 of the utility model and the rotation angle of the motor valve plug mounting tube 2 are determined after simultaneous consideration during the design, so that after the washing machine drain valve is installed, its various pipe openings can be adapted to the position layout and connection of various components of the washing machine. At the same time, the washing machine of the utility model is also provided with two second mounting holes 16 suitable for conventional drain valves to adapt to the installation of conventional drain valves. In this way, the two first mounting holes 15 are used for the installation of the washing machine drain valve with water circulation function of the utility model, and the two second mounting holes 16 are used for the installation of conventional washing machine drain valves. The bottom of the washing machine of the utility model is reserved with different mounting holes to adapt to the installation of different washing machine drain valves, so that the bottom installation of the washing machine of the utility model can be universal for conventional washing machine drain valves and washing machine drain valves of the utility model. The applicability of the washing machine of the utility model is improved.

[0050] The above is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
