Description

Technical Field

[0001] The invention belongs to the technical field of water valves, and in particular relates to an electric water valve and a washing device thereof. Background Art

[0002] As the functions of washing equipment increase, it has brought great convenience to people's daily life and has become one of the indispensable electrical appliances in people's lives. Water valves are often used for water inlet to washing equipment, and the water flow is controlled by the internal valve core. Existing water valves are generally equipped with a filter to filter out large solid particles in the water. Since the water generally contains impurities such as mud and rust in the pipes, once these impurities enter the washing machine, they will not only damage the clothes, but also damage the washing machine; in addition, the existing water valves cannot automatically process and select the water valve according to the water quality of the inlet water.

[0003] A Chinese patent application numbered CN107676495B discloses a valve system for detecting water quality, including a top cover and a transparent shell at the bottom of the top cover, a valve body at the bottom of the transparent shell, an inlet pipe on one side of the valve body, and an outlet pipe on the other side. The inlet pipe is provided with a vortex flowmeter, and the outlet pipe is provided with a conductivity sensor and a temperature sensor.

[0004] In the above technical solution, the data information of the detected water is sent to the controller through the conductivity sensor, and the controller sends the information located by the GPS locator, the information calculated by the data calculation module and the data information detected by the conductivity sensor to the monitoring module. The monitoring module sends the information to the data analysis and collation module, and the data analysis and collation module compares the information with the data in the database. The lower the conductivity, the purer the water. It mainly detects the incoming water, but cannot filter the incoming water with poor water quality. More importantly, each time the water enters, the valve system for detecting the water quality is used to distinguish different incoming water qualities, and different incoming water qualities are discharged through one outlet. The user cannot control the drainage of different water qualities, which affects the user experience.

[0005] In view of this, the present invention is proposed. Summary of the invention

The valve assembly and the water outlet are movably arranged in the valve cavity in a one-to-one correspondence, and the control unit is used to control the corresponding valve assembly to act according to the water quality information detected by the water quality detection unit. When the detected water quality is poor, the control unit controls the corresponding valve assembly to connect the waterway between the valve cavity and the water outlet, and the inlet water is discharged after filtering through the outlet provided with a filtering structure, thereby filtering the inlet water; the inlet water with better water quality is directly discharged through the outlet without a filtering structure, thereby realizing that the inlet water can be controlled to be discharged from different water outlets, thereby realizing automatic processing of the inlet water.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] like Figures 1 to 3 As shown, the electric water valve of the present invention, taking the application in a washing machine as an example, comprises a valve body 1 and a valve cavity 10 in the valve body 1, a water inlet 16 and at least two water outlets 18 are provided on the valve body 1, the water inlet 16 and the water outlets 18 are respectively connected to the valve cavity 10, at least one water outlet 18 is provided with a filtering structure, and at least one water outlet 18 is not provided with a filtering structure. The electric water valve also comprises a water quality detection unit arranged in the valve cavity 10 or the water inlet 16, a valve assembly 2 movably arranged in the valve cavity 10 corresponding to the water outlet 18 in a one-to-one correspondence, and a control unit. The water quality detection unit is used to detect the quality of the incoming water, and the control unit controls the corresponding valve assembly 2 to move according to the water quality information detected by the water quality detection unit, thereby controlling the connection and disconnection of each water outlet 18 with the valve cavity 10. On the one hand, the incoming water with poor water quality is filtered and discharged through the water outlet 18 with a filtering structure, thereby filtering the incoming water and preventing impurities such as mud, rust, etc. in the water inlet pipe from entering the washing equipment and affecting the washing equipment and the clothes in the washing equipment; on the other hand, the incoming water with good water quality is discharged through the water outlet 18 without a filtering structure, so that the incoming water can be discharged from different water outlets 18 in a controllable manner, thereby realizing automatic processing of the incoming water.

[0045] The electric water valve of the present invention takes the setting of two water outlets 18 as an example, including a first water outlet 181 and a second water outlet 182, wherein the first water outlet 181 is provided with a filtering structure, and the second water outlet 182 is not provided with a filtering structure, and the valve assembly 2 includes a first valve assembly 23 that controls the opening and closing of the first water outlet 181 and a second valve assembly 24 that controls the opening and closing of the second water outlet 182.

[0046] In the embodiment of the present invention, when the electric water valve is started, the control unit first controls the first valve assembly 23 corresponding to the first water outlet 181 to operate, so that the water path between the first water outlet 181 and the valve chamber 10 is connected, and the incoming water flows through the water quality detection unit. If the incoming water quality detected by the water quality detection unit is poor and lower than the preset value, the first valve assembly 23 is controlled to keep the first water outlet 181 open, so that the incoming water is always discharged from the first water outlet 181 after filtering. If the detected incoming water quality is good, the control unit controls the first valve assembly 23 to close the first water outlet 181, and then controls the second valve assembly 24 to open the second water outlet 182, and the incoming water with better water quality is directly discharged from the second water outlet 182.

[0047] In an embodiment of the present invention, the water quality detection unit includes a light emitting unit 12, a light receiving unit 13 and a processing unit. The light emitting unit 12 is arranged between the water inlet 16 and the valve assembly 2 close to the water inlet 16, and is used to emit a specific light source. The light source illuminates the incoming water entering the valve body 1. The light emitting unit 12 emits a specific light source through the incoming water to illuminate the light receiving unit 13. The processing unit judges the information received by the light receiving unit 13 that the light source illuminates the incoming water, and feeds the information back to the control unit.

[0048] The light receiving part 13 can be a photoresistor, and the information of the incoming water irradiated by the light source includes the resistance of the photoresistor. When the resistance of the photoresistor is lower than the preset resistance, so that the transmittance of the incoming water is higher than the preset transmittance, the water quality is good; on the contrary, if the resistance of the photoresistor is not lower than the preset resistance, so that the transmittance of the incoming water is not higher than the preset transmittance, the water quality is poor.

[0049] In the embodiment of the present invention, the valve assembly 2 reciprocates in the valve cavity 10 to move away from or close to the water outlet 18, and the water path between the valve cavity 10 and the water outlet 18 is connected by controlling the valve assembly 2 in the valve cavity 10 to move away from the water outlet 18, or the water path between the valve cavity 10 and the water outlet 18 is disconnected by controlling the valve assembly 2 in the valve cavity 10 to move close to the water outlet 18, so as to quickly respond to control the on and off of water inlet. The two valve assemblies 2 of the present invention can work together or independently.

[0050] In the embodiment of the present invention, the valve body 1 includes a first adsorption portion 14 and a reset portion 15, wherein the first adsorption portion 14 is used to provide a first force to drive the valve assembly 2 to move in a direction away from the water outlet 18, so that the water outlet 18 is connected to the valve cavity 10, and at the same time, the water path between the water inlet 16 and the water outlet 18 in the valve cavity 10 is connected, and the incoming water flows into the valve cavity 10. The reset portion 15 is used to provide a second force opposite to the first force, and the second force drives the valve assembly 2 to move in a direction close to the water outlet 18 to block the water outlet 18, so that the water outlet 18 is separated from the valve cavity 10, and at the same time, the water path between the water inlet 16 and the water outlet 18 of the valve cavity 10 is cut off.

[0051] In the embodiment of the present invention, the valve body 1 is provided with a hollow protrusion 17, and the first adsorption portion 14 and the reset portion 15 can be arranged in the protrusion 17 or in the valve cavity 10 in the valve body 1. Alternatively, the first adsorption portion 14 is arranged outside the valve body 1.

[0052] In the embodiment of the present invention, the valve assembly 2 includes a blocking portion 21 and a second adsorption portion 22. The blocking portion 21 is movably arranged in the direction from the water outlet 18 to the inside of the valve cavity 10. The blocking portion 21 is arranged in the direction from the water outlet 18 to the inside of the valve cavity 10, so that the water path between the water inlet 16 and the water outlet 18 in the valve cavity 10 is connected; the blocking portion 21 is arranged in the direction from the water outlet 18 to the inside of the valve cavity 10, so that the water path between the water inlet 16 and the water outlet 18 in the valve cavity 10 is disconnected. One end of the second adsorption portion 22 is connected to the blocking portion 21. After receiving the force applied by the first adsorption portion 14, the blocking portion 21 is driven to move in the valve cavity 10 in the direction away from the water outlet 18. The reset portion 15 is cooperatively connected with the other end of the second adsorption portion 22 to guide the direction of the reciprocating movement of the valve assembly 2, and always keep the valve assembly 2 moving on the predetermined moving trajectory.

[0053] In the embodiment of the present invention, further, the blocking portion 21 is a ball valve, the second adsorption portion 22 is a column protruding from the ball valve, the second adsorption portion 22 is radially arranged on the ball valve, and is connected with the reset portion 15. The reset portion 15 is a spring sleeved on the second adsorption portion 22, one end of the spring is connected to the valve body 1, and the other end can abut against the ball valve. Since the spring is sleeved on the outer periphery of the second adsorption portion 22, it can provide a guiding effect during the movement of the valve assembly 2. When the water inlet stops, the first adsorption portion 14 is controlled to stop providing the first force. At this time, the spring provides a reverse elastic force to drive the ball valve to drive the second adsorption portion 22 to move in the direction of the water outlet 18, blocking the water outlet 18, and completing the reset to disconnect the water outlet waterway.

[0054] In the embodiment of the present invention, further, the end portion of the water outlet 18 extending into the valve cavity 10 is trumpet-shaped, which is adapted to the shape of the ball valve. On the one hand, the contact surface between the ball valve and the end trumpet mouth is matched, and the ball valve is reset under the elastic force of the spring, and when the water outlet 18 is blocked, it cooperates with the end trumpet mouth to seal the water outlet 18, thereby improving the sealing performance of the ball valve and the trumpet-shaped end water outlet 18; on the other hand, when the ball valve is driven by the elastic force of the spring, the end trumpet mouth also plays a guiding role for the ball valve during the reset process.

[0055] Furthermore, the water outlet 18 is arranged on the inner wall of the valve cavity 10, and the inner wall of the valve cavity 10 around the water outlet 18 cooperates with the water outlet 18 to form a trumpet shape, which is adapted to the shape of the ball valve. The ball valve is reset under the elastic force of the spring, and when the water outlet 18 is blocked, it abuts against the inner wall of the valve cavity 10 to seal the water outlet 18.

[0056] Furthermore, the portion of the ball valve corresponding to the sealing water outlet 18 is made of elastic material, or a rubber layer is provided on the partial spherical surface of the ball valve corresponding to the sealing water outlet 18; preferably, the ball valve is a rubber ball or a sphere wrapped with a rubber layer, and when the spring provides elastic force to drive the ball valve to seal the water outlet 18, the ball valve can seal the water outlet 18.

[0057] Furthermore, the first adsorption part 14 in the present invention can be an electromagnet, and the second adsorption part 22 can be a permanent magnet or an iron block. Taking the permanent magnet as an example, the valve assembly 2 is driven to move by utilizing the principle of magnetic attraction. When the washing machine needs to take in water, the electromagnet is energized, and the permanent magnet is enhanced due to the magnetism of the electromagnet, and the attraction is increased. The attraction overcomes the combined force of the spring elastic force, the gravity of the ball valve and the water pressure in the valve body 1 on the ball valve, and the second adsorption portion 22 drives the ball valve to move in the direction away from the water outlet 18 until the permanent magnet and the electromagnet are adsorbed, and at the same time the water outlet 18 is connected to the valve cavity 10, that is, the water path between the water inlet 16 and the water outlet 18 is connected, and the washing machine starts to take in water; when the water inlet stops, the control electromagnet is de-energized, and the ball valve descends in the radial extension direction of the permanent magnet under the combined force of gravity, water pressure and the elastic force provided by the spring, and moves toward the water outlet 18. When the ball valve abuts and blocks the water outlet 18, the water outlet 18 is separated from the valve cavity 10, and the water path between the water inlet 16 and the water outlet 18 is disconnected, and the washing machine stops taking in water.

[0058] In the embodiment of the present invention, the filtering structure includes a filter screen 11, filter cotton 19 and activated carbon 20. The filter screen 11 is arranged in the water inlet 16, at the end away from the ball valve, the filter cotton 19 and the activated carbon 20 are also arranged in the water inlet 16, at the end close to the ball valve, and the activated carbon 20 is arranged between the two filter cottons 19, that is, the water flow at the water inlet 16 is initially filtered through the filter screen 11 to filter out large particles of solid impurities in the water flow, and then the inlet water is finely filtered through the filter cotton 19 to filter out impurities such as rust and sand in the water inlet pipe, and the activated carbon 20 is used to remove the odor in the inlet water.

[0059] When the electric water valve of the present invention is working, the control unit first controls the first valve assembly 23 corresponding to the first water outlet 181 to move, so that the water path between the first water outlet 181 and the valve cavity 10 is connected, the incoming water flows through the filter screen 11 in the water inlet 16 to complete preliminary filtration, and then flows into the valve cavity 10, flows through the water quality detection unit, and the light emitting part 12 in the water quality detection unit emits a specific light source to illuminate the incoming water. The light source shines on the photoresistor after passing through the incoming water. If the processing unit determines that the resistance value of the photoresistor is lower than the preset value, it is determined that the incoming water quality is poor, and the first valve assembly 23 is controlled to keep the first water outlet 181 open, so that the incoming water is always discharged from the first water outlet 181 after filtering. If the processing unit determines that the resistance value of the photoresistor is not lower than the preset value, it is determined that the incoming water quality is good, and the control unit controls the first valve assembly 23 to close the first water outlet 181, and then controls the second valve assembly 24 to keep the second water outlet 182 open. The incoming water with good water quality is directly discharged from the second water outlet 182.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention.
