Description

Technical Field

[0001] The present invention belongs to the technical field of shock absorption devices, and particularly relates to a shock absorption device, a laundry treatment device, and a control method for a laundry treatment device. Background Art

[0002] Laundry treatment devices such as washing machines, dryers, or shoe washing machines will inevitably vibrate during operation, thereby generating noise and even damaging the components inside the device. Therefore, shock absorption devices are often provided in existing laundry treatment devices to reduce the vibration of the laundry treatment device.

[0003] For example, a Chinese patent with the application number CN201110042695.6 discloses a fluid variable damping shock absorber, including: a shock absorber cylinder body composed of a damping cavity and a buffer cavity; a piston rod inserted into the cylinder body; a piston fixedly arranged on the piston rod in the damping cavity, and the buffer cavity communicates with the outside; a damping medium is filled in the damping cavity, and a fluid passage for the damping medium to flow through is provided in the piston. Two groups of one-way valves with opposite directions and unequal numbers are arranged on the piston. When the shock absorber moves in different directions, only one group of one-way valves in the same direction can be kept open, and the throttling effect of the one-way valves on the damping medium flowing in different directions is used to generate different damping forces when the shock absorber reciprocates.

[0004] However, when the damping medium in the shock absorber, such as grease, has a low temperature, the damping force is large and the shock absorption effect is not good. When the load eccentricity is large, problems such as noise generation, hitting the box body, or the whole machine shifting are likely to occur. The above problems are particularly likely to occur when the laundry treatment device is just started, seriously affecting the user experience.

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

[0006] The main purpose of the present invention is to solve the above technical problems, and provide a shock absorption device, a laundry treatment device, and a control method for a laundry treatment device that can quickly increase the temperature of the damping medium and reduce its damping force, achieve a better shock absorption effect, and improve the user experience.

[0007] The present invention provides the following three technical solutions to achieve the above purpose:

[0008] The first technical solution provided by the present invention is a shock absorption device, including,

[0009] A sheath, which has a chamber inside;

[0010] A moving part that reciprocates in the chamber;

[0011] A damping medium is filled between the sheath and the moving part;

[0012] It further includes:

[0013] A heating device for heating at least a part of the shock absorption device to increase the temperature of the damping medium.

[0014] Furthermore, the chamber is composed of a movement chamber and a damping chamber. The moving part reciprocates in the movement chamber, and the damping chamber is filled with a damping medium.

[0015] The heating device heats the damping part.

[0016] Furthermore, the heating device includes a PCT heating component.

[0017] Furthermore, the shock absorption device further includes a temperature sensor for detecting the temperature of the damping medium.

[0018] The second technical solution provided by the present invention is a laundry treatment device, including the shock absorption device as described above, and the shock absorption device is connected to the control system of the laundry treatment device.

[0019] The third technical solution provided by the present invention is a control method for a laundry treatment device as described above, including: controlling the opening and closing and temperature of the heating device according to the state of the damping medium in the shock absorption device.

[0020] Furthermore, obtain the current temperature of the damping medium to determine the state of the damping medium, and control the opening and closing and temperature of the heating device according to the current temperature of the damping medium.

[0021] Furthermore, when the current temperature of the damping medium is lower than the set temperature, start the heating device to heat the damping part and / or the damping medium until the current temperature of the damping medium reaches the set temperature.

[0022] Furthermore,

[0023] Adjust the motor speed of the laundry treatment device according to the current temperature of the damping medium;

[0024] When the current temperature of the damping medium is lower than the set temperature, the motor of the laundry treatment device runs at a low speed. When the current temperature of the damping medium reaches the set temperature, the motor speed of the laundry treatment device is increased to the normal speed.

[0025] Furthermore, when the current temperature of the damping medium is lower than the set temperature, the motor speed of the laundry treatment device is positively correlated with the current temperature of the damping medium.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. In the shock absorption device, clothing treatment device, and control method of a clothing treatment device provided by the present invention, the shock absorption device includes a heating device that can increase the temperature of the damping medium. By controlling the temperature of the heating device, the temperature of the damping medium can be adjusted. The temperature of the damping medium can be controlled by adjusting the temperature of the heating device to achieve the damping force required by the current device and realize the required shock absorption effect.

[0028] 2. In the shock absorption device, clothing treatment device, and control method of a clothing treatment device provided by the present invention, the shock absorption device includes a temperature sensor for detecting the temperature of the damping medium. By obtaining the current temperature of the damping medium, the state of the damping medium can be monitored in real time, and the temperature of the damping medium can be adjusted by the heating device, which can ensure that the damping medium works within an appropriate temperature range and improve the performance and stability of the shock absorption device.

[0029] 3. In the shock absorption device, clothing treatment device, and control method of a clothing treatment device provided by the present invention, when the current temperature of the damping medium is lower than the set temperature, the heating device is started to heat until the current temperature of the damping medium reaches the set temperature, which can enable the damping medium to quickly reach an appropriate temperature range and improve the performance and stability of the shock absorption device.

[0030] 4. In the shock absorption device, clothing treatment device, and control method of a clothing treatment device provided by the present invention, when the current temperature of the damping medium is lower than the set temperature, the motor speed of the clothing treatment device is adjusted and reduced, so that when the clothing treatment device is just started, it will not cause excessive vibration and noise due to the high damping force of the damping medium in the shock absorption device and the high-speed rotation of the motor, thus improving the user experience.

[0035] 200, moving part;

[0036] 300, heating device.

[0037] It should be noted that these drawings and textual descriptions are not intended to limit the scope of the concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Embodiments

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] [Embodiment 1]

[0040] As Figure 1 shown, this embodiment provides a shock absorption device, which is applicable to any equipment that needs to install a shock absorption device, such as household appliances like washing machines and dryers, or various large industrial equipment.

[0041] Furthermore, the shock absorption device includes a sheath 100 and a moving part 200. Among them, the interior of the sheath 100 has a chamber, and the moving part 200 makes reciprocating movements in the chamber. When the equipment equipped with this shock absorption device vibrates, the reciprocating movement of the moving part 200 is used to absorb vibration energy, preventing displacement, noise, etc., and improving the stability and safety performance of the equipment.

[0042] In a preferred embodiment, a damping medium is filled between the sheath 100 and the moving part 200. On the one hand, it plays a lubricating role to enable the moving part 200 to perform reciprocating movements more smoothly. On the other hand, it provides damping to improve the shock absorption effect of the shock absorption device.

[0043] Among them, the damping medium is preferably grease.

[0044] It should be noted that the melting range of organic substances such as grease is not a single temperature point, but a temperature interval, which is called the melting range interval. The two limits are respectively called the initial melting temperature and the final melting temperature. The initial melting temperature is the temperature at which the substance begins to melt, and the final melting temperature is the temperature at which the substance is completely melted. When the temperature of the grease is within the melting range interval, its state is a softened state between solid and liquid, and its fluidity increases and viscosity decreases as the temperature rises.

[0045] The melting ranges of commonly used greases are basically within the daily temperature range of the human living environment. Therefore, when the temperature is relatively low, the grease will be in a softened state, its damping force increases, and the shock absorption effect of the shock absorption device will decrease. At even lower temperatures, the grease may solidify, further hindering the movement of the moving part 200.

[0046] During the operation of the device, over time, under the action of friction, the temperature of the damping medium gradually rises, the damping medium gradually melts, the viscosity gradually decreases, the damping force gradually decreases, and the damping effect of the damping device gradually improves. Therefore, when the device is just started, vibrations occur particularly frequently, especially in the case of low temperatures.

[0047] Therefore, in a preferred embodiment, the damping device further includes a heating device 300 for heating at least a part of the damping device to rapidly increase the temperature of the damping medium.

[0048] It should be noted that the purpose of setting the heating device 300 is not limited to rapidly melting the solidified or softened damping medium into a liquid state. Because for different devices or different working states of the same device, the damping requirements for the damping device are different. The temperature of the damping medium can be controlled by adjusting the temperature of the heating device 300 to achieve the damping force required for the current device and realize the required damping effect.

[0049] Furthermore, the damping device further includes a temperature sensor for detecting the temperature of the damping medium. By controlling the temperature of the heating device 300, the temperature of the damping medium can be adjusted, which can ensure that the damping medium works within an appropriate temperature range and improve the performance and stability of the damping device.

[0050] In a preferred embodiment, the heating device 300 includes a PCT heating component disposed outside the protective sleeve 100. After the heating device 300 is activated, the PCT heating component generates heat, and the heat is transferred through the protective sleeve 100 to the damping medium inside the protective sleeve 100 to achieve rapid temperature increase.

[0051] Furthermore, the heating device 300 can be arranged to cover the entire stroke range of the reciprocating movement of the moving part 200, so that the damping medium can be rapidly heated up in the shortest time;

[0052] The heating device 300 can also be arranged to cover a part of the stroke range of the reciprocating movement of the moving part 200. Under the drive of the reciprocating movement of the moving part 200, the heat is transferred and dispersed, and the damping medium is gradually heated up, which can reduce the power consumption and the cost of the heating device 300.

[0053] In a preferred embodiment, the protective sleeve 100 and / or the moving part 200 of the damping device are made of materials with strong thermal conductivity to accelerate the heat transfer process of the heating device 300 and accelerate the temperature increase rate of the damping medium.

[0054] [Embodiment 2]

[0055] This embodiment provides a shock absorption device. The difference from Embodiment 1 is that in the shock absorption device of this embodiment, its chamber is composed of a movement chamber and a damping chamber. The moving part 200 makes reciprocating movements in the movement chamber, the damping chamber is filled with a damping medium, and the heating device 300 is arranged outside the damping part to heat the damping part.

[0056] The shock absorption device in this embodiment includes a damping chamber. By controlling the internal temperature of the damping medium therein through the heating device 300, its damping force can be adjusted more effectively, realizing the variable damping function of the shock absorber to adapt to different working conditions.

[0057] [Embodiment 3]

[0058] This embodiment provides a laundry treatment device, in which the shock absorption device provided in the foregoing embodiment is provided, and the shock absorption device is connected to the control system of the laundry treatment device.

[0059] Among them, the laundry treatment device includes, but is not limited to, washing machines, dryers, washer-dryers, small underwear washing machines, shoe washing machines, and the like.

[0060] [Embodiment 4]

[0061] This embodiment provides a control method for the laundry treatment device provided in the foregoing embodiment. Specifically, the control method includes: controlling the opening and closing of the heating device and its temperature according to the state of the damping medium in the shock absorption device.

[0062] In a preferred implementation manner, the state of the damping medium is determined by obtaining the current temperature of the damping medium. Exemplarily, when the current temperature of the damping medium is lower than the initial melting temperature of its melting range, it indicates that its current state is solid; when the current temperature is higher than the final melting temperature of its melting range, it indicates that it is currently liquid; when the current temperature is within the melting range, its state is a softened state between solid and liquid.

[0063] Further, when the damping medium is solid, the heating device is turned on to increase the temperature of the damping medium. When the damping medium is liquid or in a softened state, whether to turn on the heating device is selected according to the magnitude of the required damping force, and the temperature of the heating device is controlled to adjust the temperature of the damping medium. That is to say, the opening and closing of the heating device and its temperature are controlled according to the current temperature of the damping medium.

[0064] In a preferred implementation manner, when the current temperature of the damping medium is lower than the set temperature, the heating device is started to heat until the current temperature of the damping medium reaches the set temperature.

[0065] Further, the set temperature can be a fixed value pre-stored in the control system of the laundry treatment device at the time of factory shipment, corresponding to the temperature of the damping medium when the shock absorption device has the best shock absorption effect during the daily use of the device, generally a value higher than the initial melting temperature of the damping medium.

[0066] Furthermore, the set temperature can also be an adjustable value. Specifically, the adjustment methods include, but are not limited to:

[0067] Adjust according to the instructions of the user or staff, and,

[0068] Automatically adjust according to the load of the laundry treatment device or the eccentricity value of its washing tub.

[0069] Generally speaking, a high load or a high eccentricity value corresponds to a lower damping force of the damping medium and a higher corresponding temperature.

[0070] In a preferred embodiment, the control method of the laundry treatment device further includes: controlling the opening and closing and temperature of the heating device according to the ambient temperature. Specifically, the opening and closing and temperature of the heating device can be controlled according to the difference between the ambient temperature and the set temperature.

[0071] Further, the positive or negative of the difference can be used to determine whether the ambient temperature is higher or lower than the set temperature, as a judgment condition for the heating device to start. When the ambient temperature is greater than or equal to the set temperature, the heating device does not start, and when the ambient temperature is less than the set temperature, the heating device will start.

[0072] Furthermore, the magnitude of the difference can be used to adjust the temperature of the heating device. When the difference is small, the normal heating temperature is sufficient to quickly heat the damping medium; when the difference is large, it means that the ambient temperature is much lower than the set temperature, and at this time the temperature of the heating device is increased to more quickly increase the temperature of the damping medium.

[0073] In a preferred embodiment, the magnitude of the difference between the ambient temperature and the set temperature is also used to control the heating duration of the heating device.

[0074] When the difference is small, the ambient temperature is close to the set temperature. During the reciprocating movement of the moving parts, the heat generated by friction is sufficient to support the damping medium to maintain the temperature until the operation ends. When the damping medium is heated to the set temperature, the heating device stops working, and the current temperature of the damping medium will not drop rapidly.

[0075] When the difference is large, it indicates that the ambient temperature is much lower than the set temperature, and the heat generated by friction is insufficient. If the heating device stops working, the current temperature of the damping medium will drop rapidly. At this time, after the damping medium is heated to the set temperature, the heating device keeps working at a heat preservation temperature to keep the damping medium warm, avoiding the rapid attenuation of the service life caused by the repeated start-up and stop of the heating device.

[0076] [Embodiment 5]

[0077] Based on Embodiment 4, this embodiment provides a control method for a laundry treatment device, including: adjusting the motor speed of the laundry treatment device according to the current temperature of the damping medium.

[0078] Specifically, when the current temperature of the damping medium is lower than the set temperature, the temperature of the damping medium in the shock absorber is too low to effectively absorb shock. At this time, the motor speed of the laundry treatment device is reduced to operate at a low speed, that is, lower than the normal speed set in the normal operation program; when the current temperature of the damping medium reaches the set temperature, the motor speed of the laundry treatment device is increased to the normal speed. The laundry treatment device will not have situations such as excessive vibration and noise caused by the high damping force of the damping medium in the shock absorber and the high-speed rotation of the motor, improving the user experience.

[0079] Further, when the current temperature of the damping medium is lower than the set temperature, the motor speed of the laundry treatment device is positively correlated with the current temperature of the damping medium. Especially when the current temperature is close to the set temperature, the viscosity of the damping medium decreases with the increase of the current temperature. Therefore, the motor speed gradually increases with the increase of the current temperature of the damping medium. On the one hand, it is beneficial to the smooth operation of the laundry treatment device, and on the other hand, it promotes the reciprocating movement of the moving parts, promotes heat generation by friction to assist in heating up, and enables the uniform and rapid transfer of the heat generated by the heating device and the heat generated by friction in the damping medium.
