Description

Technical Field

[0001] The invention belongs to the field of washing equipment, and in particular relates to a waterproof device for a vibration-damping component of a washing machine and an adjustment method thereof. Background Art

[0002] The current washing machine vibration reduction system uses a suspension rod equipped with a damping spring for vibration reduction, and the vibration reduction system uses a waterproof cap structure, which can effectively block the condensed water sliding down the suspension rod, but cannot provide good protection against the condensed water splashing in from all sides. At the same time, during the washing and dehydration process of the washing machine, the inner drum of the washing machine rotates at high speed, and the waterproof cap cannot prevent the condensed water from being thrown off the outer drum of the washing machine and dripping onto the vibration reduction suspension rod, causing the condensed water to slide from the suspension rod between the waterproof cap and the support seat into the inside of the casing, causing the vibration reduction component to fail.

[0003] The Chinese patent application number 201910734546.2 discloses a vibration reduction device for a washing machine and a washing machine. The vibration reduction device includes a suspension rod and an upper support assembly sleeved on the outside of the suspension rod. A waterproof cap is also provided on the outside of the suspension rod. The waterproof cap cooperates with the upper support assembly to prevent water from entering the inside of the suspension rod along the suspension rod. It can provide good protection for the condensed water that condenses and slides down the suspension rod, but it cannot provide good protection for the condensed water that splashes out during the use of the washing machine. This part of the condensed water usually flows into the vibration reduction component through two parts, causing the vibration reduction component to rust inside, resulting in increased friction, increased damping force, and loss of vibration reduction effect, which makes the whole machine noisier during use.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The first aspect of the present invention provides a waterproof device for a vibration-damping component of a washing machine. The waterproof cap is adsorbed on a support seat through the magnetic attraction between magnetic suction units, thereby effectively solving the problem of failure of the vibration-damping component caused by splashing of condensed water during operation of the washing machine.

[0006] A second aspect of the present invention provides a method for adjusting a waterproof device of a vibration-damping component of a washing machine.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A waterproof device for a vibration-damping component of a washing machine comprises a waterproof cap and a support seat, wherein magnetic units are arranged inside the waterproof cap and the support seat; the waterproof cap is adsorbed on the support seat by the suction force between the magnetic units.

[0009] Furthermore, a first magnetic unit is provided in the waterproof cap; a second magnetic unit is provided in the support seat; and at least one of the first magnetic unit and the second magnetic unit is an electromagnet.

[0012] Furthermore, a surface of the water retaining portion opposite to the support seat is a water guiding surface inclined from the center to the periphery; the diameter of the water retaining portion is larger than the diameter of the support seat, and is used to be buckled on the support seat.

[0013] Advantageously, the inclined water guide surface can ensure that the water is better guided downward to prevent it from entering the interior of the vibration-damping component.

[0014] Furthermore, the support seat and the waterproof cap are both integrally injection molded.

[0015] Furthermore, the waterproof device for the vibration-damping component of the washing machine also includes: an adjusting unit for adjusting the magnetic force of the electromagnet.

[0016] Furthermore, the adjustment unit includes: a sensor for detecting the bearing force of the inner and outer barrels and outputting a current value; and a control motor for receiving the current value output by the sensor and transmitting the current value to the electromagnet.

[0017] A second aspect of the present invention provides a method for adjusting a waterproof device of a vibration-damping component of a washing machine, comprising:

[0018] S1, sensor detects the load-bearing capacity of the inner and outer barrels of the washing machine;

[0019] S2, calculate the current value according to the formula F=nILB, and transmit the current value to the control motor;

[0020] Among them: n is the number of turns of the coil (quantitative), L is the length of the wire perpendicular to the direction of the magnetic field (quantitative), B is the magnetic induction intensity (quantitative), I is the current (controllable variable), and F is the load-bearing capacity of the inner and outer drums when the washing machine is running (uncontrollable variable).

[0021] S3, control the motor to adjust the magnetic force of the electromagnet according to the current value.

[0022] Optionally, a method for using a sensor to detect the bearing capacity of inner and outer drums of a washing machine includes: powering on the washing machine; the sensor detecting the rotation speed of the washing machine; and detecting the bearing capacity of the inner and outer drums according to the rotation speed of the washing machine.

[0023] Optionally, the method of controlling the motor to adjust the magnetic force of the electromagnet according to the current value includes:

[0024] Control the motor to receive the current value transmitted by the sensor;

[0025] Control the motor to transmit the current value to the electromagnet;

[0026] The electromagnet generates a magnetic field according to the value of the current it receives.

[0027] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: a magnetic suction unit is arranged on the waterproof cap and the support seat, and the waterproof cap is adsorbed on the mounting seat through the adsorption effect of the magnetic suction unit, which can effectively prevent the splashing of condensed water from causing the failure of the vibration damping component, thereby solving the problem of rusting of the vibration damping component and reducing the problem of excessive noise during the operation of the machine due to the failure of the vibration damping component; in addition, the problem of shortening the service life of the vibration damping component due to rusting is avoided to a great extent.

[0037] 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.

[0038] In a first aspect of the present invention, a waterproof device for a vibration-damping component of a washing machine is provided. Figure 1 As shown, it includes a waterproof cap 1 and a supporting seat 2.

[0039] Furthermore, a first magnetic unit 111 is provided in the waterproof cap 1, and a second magnetic unit 21 is provided in the support base 2. The waterproof cap 1 and the support base 2 are adsorbed together by the attraction between the magnetic units.

[0040] Specifically, a first magnetic unit 111 is arranged inside the waterproof cap 1, and a second magnetic unit 21 is arranged inside the support seat 2. The first magnetic unit 111 and the second magnetic unit 21 are in relative positions. The waterproof cap 1 is adsorbed on the support seat 2 through the suction force between the first magnetic unit 111 and the second magnetic unit 21.

[0041] Furthermore, at least one of the first magnetic attraction unit 111 and the second magnetic attraction unit 21 is an electromagnet.

[0042] Advantageously, the electromagnet can be provided to adjust the magnitude of the magnetic force when necessary to ensure that the waterproof cap 1 is always adsorbed on the support seat 2.

[0043] Furthermore, the waterproof cap 1 includes a sealing sleeve 11 and a water retaining portion 12 extending outwardly from the sealing sleeve 11 , and the first magnetic attraction unit 111 is disposed in the sealing sleeve 11 .

[0044] Furthermore, a surface of the water retaining portion 12 opposite to the support seat 2 is a water guiding surface inclined from the center toward the periphery.

[0045] Advantageously, the water retaining portion 12 and the side opposite to the support seat 2 are arranged horizontally to ensure that when the two are adsorbed together, no gap is left, causing condensed water to enter the interior of the vibration-damping component; the opposite side is arranged as an inclined surface, which can better ensure that the water flows down and does not enter the interior of the vibration-damping component.

[0046] Specifically, the sealing sleeve 11 and the water retaining portion 12 cooperate to form an umbrella-shaped structure.

[0047] Furthermore, the diameter of the water retaining portion 12 is larger than the diameter of the support seat 2 , and is used to be buckled on the support seat 2 .

[0048] Furthermore, the support base 2 is formed by integral injection molding; the waterproof cap 1 is formed by integral injection molding.

[0049] Specifically, the second magnetic unit 21 is installed in the support base 2 , and then the support base 2 is moved to ensure that the second magnetic unit 21 does not fall off in the support base 2 .

[0050] Specifically, the first magnetic unit 111 is installed in the waterproof cap 1 , and then the waterproof cap 1 and the first magnetic unit 111 are injection molded at one time, which can ensure that the first magnetic unit 111 will not fall out of the waterproof cap 1 .

[0051] In this embodiment, the waterproof device of the vibration-damping component of the washing machine further includes a sleeve 3 , the support base 2 is installed above the sleeve 3 , and the diameter of the support base 2 is smaller than the diameter of the sleeve 3 .

[0052] Specifically, the water retaining part 12 has a larger diameter than the support seat 2 and is snapped onto the support seat 2 . The water retaining part 12 also has a larger diameter than the sleeve 3 , which can effectively prevent water on the water retaining part 12 from flowing into the sleeve 3 .

[0053] Furthermore, the waterproof device for the vibration-damping component of the washing machine also includes a suspension rod 4 , and the sleeve 3 , the support seat 2 and the waterproof cap 1 are sleeved on the outside of the suspension rod 4 .

[0054] Advantageously, the sleeve 3, the support seat 2 and the waterproof cap 1 are sleeved on the outside of the suspension rod 4, which can ensure that the three are on the same axis.

[0055] Furthermore, the waterproof device for the vibration-damping component of the washing machine also includes an adjusting unit for adjusting the magnetic force of the electromagnet.

[0056] Furthermore, the adjustment unit includes a sensor for detecting the bearing force of the inner and outer barrels and outputting a current value; a control motor for receiving the current value output by the sensor and transmitting the current value to the electromagnet.

[0057] Specifically, the set sensor first determines whether the speed of the washing machine is low or high, then obtains the bearing capacity of the inner and outer barrels of the washing machine, calculates the required current value through the basic formula of electromagnetic force, and outputs the current value.

[0058] Specifically, the control motor communicates with the sensor and is electrically connected to the electromagnetic coil. When the sensor obtains the current value based on the bearing force of the inner and outer barrels, the obtained current value signal is transmitted to the control motor. The control motor obtains the current value signal, obtains the required current value, and transmits the current value to the electromagnetic coil. The electromagnetic coil obtains the current value, and then generates a corresponding magnetic force.

[0059] A second aspect of the present invention provides a method for adjusting a waterproof device of a vibration damping component of a washing machine, such as Figure 2 shown.

[0060] In step S1, the sensor detects the bearing capacity of the inner and outer tubs of the washing machine.

[0061] Before detecting the bearing capacity of the inner and outer barrels of the washing machine, steps S11 to S13 are included.

[0062] In step S11, the washing machine is powered on and starts to operate.

[0063] In step S12, the sensor detects the rotation speed of the washing machine.

[0064] In step S13, the bearing capacity of the inner and outer tubs of the washing machine is detected according to the rotation speed of the washing machine.

[0065] In step S2, the current value is calculated according to the formula F=nILB, and the current value is transmitted to the control motor.

[0066] It should be noted that n is the number of coil turns (quantitative), L is the length of the wire perpendicular to the direction of the magnetic field (quantitative), B is the magnetic induction intensity (quantitative), I is the current (controllable variable), and F is the load-bearing capacity of the inner and outer drums when the washing machine is running (uncontrollable variable).

[0067] In step S3, the motor is controlled to adjust the magnetic force of the electromagnet according to the current value.

[0068] The method for controlling the motor to adjust the magnetic force of the electromagnet according to the current value specifically includes S31 to S33.

[0069] In step S31 , the motor is controlled to receive the current value transmitted by the sensor.

[0070] In step S32, the motor is controlled to transmit the current value to the electromagnet.

[0071] In step S33, the electromagnet generates a corresponding magnetic field according to the received current value.

[0072] In this embodiment, the washing machine applies the above-mentioned washing machine vibration reduction component waterproof device and adjustment method.

[0073] In this embodiment, the washing machine includes a housing, an outer tub and a vibration reduction device, and the vibration reduction device applies the above-mentioned waterproof device.

[0074] In this embodiment, the vibration-damping component waterproof device includes a suspension rod 4, one end of which is connected to the outer barrel of the washing machine, and the other end is connected to the washing machine body. During the washing or dehydration process of the washing machine, the vibration-damping component realizes the vibration-damping effect between the outer barrel and the body.

[0075] In this embodiment, the waterproof device of the vibration-damping component includes: a waterproof cap 1, which has a first magnetic unit 111 disposed therein; a support base 2, which has a second magnetic unit 21 disposed therein; the waterproof cap 1 and the support base 2 are fastened together by magnetic attraction.

[0076] Specifically, the waterproof cap 1 is buckled on the support base 2. In order to prevent the waterproof cap 1 from being separated from the support base 2 due to shaking of the washing machine, a first magnetic unit 111 is set in the waterproof cap 1, and a second magnetic unit 21 is set in the support base 2. The waterproof cap 1 is adsorbed on the support base 2 through the suction force between the first magnetic unit 111 and the second magnetic unit 21 to prevent the waterproof cap 1 from being separated from the support base 2, causing condensed water to enter the vibration damping component along the suspension rod 4.

[0077] In this embodiment, at least one of the first magnetic unit 111 and the second magnetic unit 21 is an electromagnet.

[0078] In this embodiment, the waterproof cap 1 includes a sealing portion and a water retaining portion 12 extending from the sealing portion to the periphery, and the first magnetic unit 111 is arranged inside the sealing portion. The side of the water retaining portion 12 opposite to the support seat 2 is a water guide surface inclined from the center to the periphery. The caliber of the water retaining portion 12 is larger than the caliber of the support seat 2, which can ensure that the water retaining portion 12 is buckled on the support seat 2 to prevent condensed water from entering the vibration damping component.

[0079] In this embodiment, the vibration reduction component of the washing machine further includes a sleeve 3 , and the sleeve 3 , the support seat 2 and the waterproof cap 1 are all arranged on the outside of the suspension rod 4 .

[0080] In this embodiment, the support seat 2 is installed on the sleeve 3, and the support seat 2, the sleeve 3 and the second magnetic unit 21 are integrally injection molded; the waterproof cap 1 is injection molded once, and at the beginning of the injection molding of the waterproof cap 1, the first magnetic unit 111 is first installed on the sealing part of the waterproof cap 1.

[0081] In this embodiment, the vibration reduction component waterproofing device also includes a sensor and a control motor. The sensor transmits a current value to the control motor, and the control motor transmits the received current value to the electromagnet to ensure that it generates a corresponding magnetic force.

[0082] The specific adjustment method of the waterproof device of the vibration-damping component is that when the washing machine is not powered on, the waterproof cap 1 and the support seat 2 are adsorbed together by the suction force between the first magnetic unit 111 and the second magnetic unit 21, ensuring that the waterproof cap 1 will not detach from the support seat 2.

[0083] When the washing machine is powered on, the sensor first determines the operating state of the washing machine, whether it is low speed or high speed, and calculates the load-bearing capacity of the inner and outer barrels of the washing machine based on the speed of the washing machine, and then calculates the current value based on the basic formula: F=nILB.

[0084] It should be noted that in the formula F=nILB, n is the number of coil turns (quantitative), L is the length of the wire perpendicular to the direction of the magnetic field (quantitative), B is the magnetic induction intensity (quantitative), I is the current (controllable variable), and F is the load-bearing capacity of the inner and outer drums when the washing machine is running (uncontrollable variable).

[0085] The sensor transmits the calculated current value to the control motor. After receiving the current value, the control motor transmits it to the electromagnet. The electromagnet generates a corresponding electromagnetic force according to the size of the received current value. The waterproof cap 1 is adsorbed on the support seat 2 through the electromagnetic force and the magnetic force between the second magnetic unit 21 and the first magnetic unit 111. This can effectively prevent the washing water from splashing from the side into the inside of the sleeve 3 and the water vapor condensing into the inside, thereby preventing the vibration reduction component from rusting due to the water vapor condensing and flowing into the inside, thereby ensuring the stability of the damping force.
