DETAILED DESCRIPTION OF THE EMBODIMENTS

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, 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 here are only used to explain the present invention and are not used to limit the present invention.

[0038] [Embodiment 1]

[0039] This embodiment provides a laundry treatment device, which includes a housing and a drum. The drum is used to hold clothes and is connected to a motor. By starting the motor, the drum rotates and vibrates to treat the clothes. As an example, the laundry treatment device includes, but is not limited to, washing machines, shoe washing machines, dryers, washer-dryers, and combined washing machines, etc.

[0040] Furthermore, in the laundry treatment device provided in this embodiment, a counterweight portion is provided on at least one side wall of the housing. The counterweight portion has a cavity. By injecting or discharging a counterweight fluid into the cavity of the counterweight portion, the weight of the laundry treatment device can be increased or decreased. In this way, when the laundry treatment device leaves the factory, the counterweight portion can be in an empty state to reduce the overall weight and transportation cost. After the laundry treatment device is delivered to the installation location, such as the user's home, after installation, the counterweight fluid is injected into the counterweight portion to increase the weight of the machine and reduce the vibration that may occur during operation.

[0041] Furthermore, the housing of the laundry treatment device generally has a rectangular parallelepiped shape as a whole, and the drum is cylindrical. Its opening is upward or forward and is arranged inside the housing. Correspondingly, the door for taking in and out clothes is arranged on the top or the front side of the housing. To ensure the balance of the laundry treatment device, preferably, the counterweight portion is symmetrically arranged on the housing of the laundry treatment device, such as on the left and right side walls.

[0042] It should be noted that symmetrically arranging the counterweight portion on the side wall of the housing is more conducive to weight dispersion compared to arranging the counterweight inside the laundry treatment device, and it is less likely to cause the body to shake, and the effect of shock absorption and noise reduction is better.

[0043] Furthermore, the counterweight fluid can be a liquid such as water or oil, or a solid such as sand or gravel. The counterweight portion is provided with an inlet and an outlet to facilitate the injection and discharge of the counterweight fluid. The positions of the inlet and outlet are set by those skilled in the art according to the actual situation. It should be noted that there are also air holes on the counterweight portion. When injecting or discharging the counterweight fluid, the air in the wall body is discharged through the air path or the outside air enters, making the injection and discharge process of the counterweight fluid smoother.

[0044] Furthermore, the process of adding the counterweight fluid into the counterweight portion can be manually performed by the user or the installer, or it can be automatically performed by the laundry treatment device by connecting an external container or pipeline containing the counterweight fluid and injecting the counterweight fluid into the counterweight portion through a pump or the pressure of the counterweight fluid.

[0045] In some embodiments, the counterweight part is suspended on the side wall of the outer shell. This way has a simpler structure and lower cost. Using this solution can also achieve the transformation of old equipment. By adding connection structures such as hooks, or by pasting, welding, etc., the counterweight part is added to the side wall of the laundry treatment equipment, and the connection of the pipeline and circuit can be adjusted adaptively. Preferably, the counterweight part is arranged inside the outer shell, and the counterweight part can be hidden inside the laundry treatment equipment to take into account the aesthetics.

[0046] In some embodiments, a sandwich structure is provided in the side wall of the outer shell, and the counterweight part is arranged in the sandwich. In this way, on the one hand, the integrity of the outer shell is better and more solid, and the arrangement of the pipeline and circuit is also more free. There is no need to consider avoiding the internal structure of the laundry treatment equipment, and it is also more beautiful; on the other hand, the air in the sandwich and the counterweight part can also play a certain role in absorbing vibration and noise. Further, the counterweight part can also be directly formed by the sandwich, and the cavity in the sandwich is used to accommodate the counterweight fluid.

[0047] In a preferred embodiment, the counterweight part is a tubular structure. Specifically, the tubular counterweight part is arranged in the sandwich of the side wall of the outer shell, arranged in an S shape, or extended in a snake shape, spiral, etc., and its pipe diameter, size, etc. are not limited. Further, the shape of the counterweight part and the volume of its cavity can be set according to the shape, volume of the laundry treatment equipment and the required counterweight weight.

[0048] Since water is relatively easy to obtain in daily life, and its injection, discharge, storage and transportation are relatively easy, it is an ideal choice for the counterweight fluid. The following counterweight fluid takes water as an example for further description.

[0049] When the laundry treatment equipment is a dryer or other equipment that does not need to be connected to tap water itself, a channel for injecting and discharging the counterweight fluid can be separately provided for the counterweight part. For example, a connecting pipe connecting the counterweight part to a faucet and a sewer is provided.

[0050] When the laundry treatment equipment is a washing machine or other equipment that needs to be connected to tap water, it includes a water circuit system, including a water inlet pipe and a drain pipe.

[0051] Specifically, taking a washing machine as an example, the water inlet end of the water inlet pipe is connected to a faucet arranged outside the washing machine or a direct connection tap water pipeline without a faucet, and the water outlet end is connected to the water inlet of the drum. An inlet valve is arranged in the water inlet pipe. When the washing machine needs to fill water, the inlet valve is opened, and the water in the tap water pipeline enters the drum through the water inlet pipe under the action of its own water pressure.

[0052] The inlet end of the drain pipe is connected to the laundry tub, generally connected to the bottom of the laundry tub to fully drain the water in the laundry tub during drainage, avoiding water accumulation in the laundry tub; the outlet end of the drain pipe is connected to the sewer, and the water used for washing or rinsing is discharged through the drain pipe. Some washing machines are provided with a drain valve in the drain pipe to drain water by opening the drain valve. Some washing machines are also provided with a drain pump to improve the drainage efficiency, and the drain pump is started to drain the water faster and more thoroughly.

[0053] Furthermore, the counterweight part is connected to the water circuit system, and the counterweight fluid is water to realize water injection into the counterweight part during the water inlet or drainage process of the washing machine.

[0054] In some embodiments, the counterweight part can be connected in series or in parallel to the water inlet pipe or the drain pipe, which will be specifically described in Embodiments 2-5 below.

[0055] In some embodiments, the water inlet and the drain outlet of the counterweight part are respectively connected to the water inlet pipe and the drain pipe, which will be specifically described in Embodiment 6 below.

[0056] In some embodiments, the laundry treatment device has the function of spray water inlet. In addition to the water inlet of the laundry tub, spray heads are also arranged at other positions of the laundry treatment device. At this time, the spray heads can be connected to the counterweight part through a spray pipeline, and the water in the counterweight part is used for spraying. At this time, it is required that the water in the counterweight part is unused clean water.

[0057] [Embodiment 2]

[0058] As Figure 1 shown, in this embodiment, the counterweight part 4 is connected in series to the water inlet pipe 2.

[0059] When the washing machine intakes water, the water inlet valve is opened, and the water flows along the water inlet pipe 2, enters the cavity of the counterweight part 4 through the water inlet of the counterweight part 4, then flows out through the water outlet of the counterweight part 4, and finally enters the laundry tub 1 through the water inlet of the laundry tub 1.

[0060] In this way, the counterweight part 4, as a part of the water inlet pipe 2, can be filled with water during the water inlet process to increase the counterweight of the washing machine, and the vibration and noise can be reduced during the washing or drying steps.

[0061] Preferably, the position of the water outlet of the counterweight part 4 should be at least higher than the lowest point of the counterweight part 4, so as to avoid the situation that water directly flows out of the counterweight part 4 from the water outlet without accumulating in the counterweight part 4 during water inlet, making the liquid injection of the counterweight part 4 more sufficient and effective.

[0062] Further, the counterweight portion 4 is also connected to the drain pipe 3 or the sewer through a drain branch, and a solenoid valve is provided in the drain branch to control the opening and closing of the drain branch. When moving or transporting the washing machine or other situations where weight reduction is required, the solenoid valve is opened, and the water in the counterweight portion 4 is discharged through the drain branch.

[0063] [Embodiment 3]

[0064] As Figure 2 shown, the difference from the foregoing embodiment is that in this embodiment, the counterweight portion 4 is connected in parallel to the water inlet pipe 2.

[0065] When the washing machine is filling with water, the water flows in two paths:

[0066] One path flows along the water inlet pipe 2;

[0067] The other path flows along the water inlet path of the counterweight portion 4, enters the cavity of the counterweight portion 4 through the water inlet of the counterweight portion 4, and in case of need, the water in the counterweight portion 4 can flow out through the water outlet;

[0068] Finally, the two water flows converge, or separately, and enter the drum 1 through the water inlet of the drum 1. Optionally, the two water flows can also enter the drum 1 through different water inlets.

[0069] Preferably, a first solenoid valve and a second solenoid valve are respectively provided at the connections of the water inlet and the water outlet of the counterweight portion 4 with the water inlet pipe 2, and the opening and closing of the water inlet pipe 2 and / or the water inlet path of the counterweight portion 4 are controlled by controlling the two solenoid valves, and the function of filling water into the drum 1 alone or filling water into the counterweight portion 4 alone can be achieved.

[0070] Further preferably, a flow sensor or a weight sensor can also be provided in the counterweight portion 4 to monitor the water volume in the counterweight portion 4. When the water volume in the counterweight portion 4 reaches the set amount, the first solenoid valve and the second solenoid valve are controlled to close the water inlet path and the water outlet path of the counterweight portion 4, and the water volume in the counterweight portion 4 will no longer change, realizing the quantitative control of the weight of the counterweight portion 4.

[0071] [Embodiment 4]

[0072] As Figure 3 shown, the difference from the foregoing embodiment is that in this embodiment, the counterweight portion 4 is connected in series to the drain pipe 3.

[0073] When the washing machine is draining, the drain valve and / or the drain pump is opened, the water flows along the drain pipe 3, enters the cavity of the counterweight portion 4 through the water inlet of the counterweight portion 4, then flows out through the water outlet of the counterweight portion 4, and finally is discharged from the washing machine.

[0074] In this way, the counterweight part 4, as a part of the drain pipe 3, can be filled with water during the drainage process to increase the counterweight of the washing machine, achieving the secondary utilization of the waste water and having the technical effect of saving water. It should be noted that in this embodiment, the drain valve and / or the drain pump can also be opened simultaneously during the water inlet process to fill the counterweight part 4 with water during the water inlet process.

[0075] For the other solutions of this example, reference can be made especially to Embodiment 2.

[0076] [Embodiment 5]

[0077] As Figure 4 shown, the difference from the foregoing embodiments is that in this embodiment, the counterweight part 4 is connected in parallel to the drain pipe 3.

[0078] When the washing machine drains water, the water flows in two paths:

[0079] One path flows along the drain pipe 3;

[0080] The other path flows along the water inlet path of the counterweight part 4, enters the cavity of the counterweight part 4 through the water inlet of the counterweight part 4, and in case of need, the water in the counterweight part 4 can flow out through the water outlet; [[ID=2l]]

[0081] Finally, the two paths of water flow converge, or separately, and are discharged from the washing machine through the drain pipe 3.

[0082] In this embodiment, the drain valve and / or the drain pump can also be opened simultaneously during the water inlet process of the drum 1 to fill the counterweight part 4 with water during the water inlet process.

[0083] For the other solutions of this example, reference can be made especially to Example 3.

[0084] [Embodiment 6]

[0085] As Figure 5 shown, in this embodiment, the water inlet and the water outlet of the counterweight part 4 are respectively connected to the water inlet pipe 2 and the drain pipe 3.

[0086] When the washing machine intakes water, the water flows in two paths:

[0087] One path flows along the water inlet pipe 2;

[0088] The other path flows along the water inlet path of the counterweight part 4, enters the cavity of the counterweight part 4 through the water inlet of the counterweight part 4, and then flows out through the water outlet of the counterweight part 4;

[0089] Finally, the two paths of water flow converge, or separately, and are discharged from the washing machine through the drain pipe 3, or are drained separately by controlling the solenoid valve.

[0090] A first solenoid valve and a second solenoid valve are respectively arranged at the water inlet and the water outlet of the counterweight part 4 and the connection parts of the water inlet pipe 2 and the drain pipe 3. By controlling the two solenoid valves, the opening and closing of the water circuits of the water inlet pipe 2 and / or the counterweight part 4 can be controlled, and the functions of separately filling water into the drum 1 or separately filling water into the counterweight part 4 can be realized.

[0091] [Embodiment 7]

[0092] The difference from the foregoing embodiment is that in this embodiment, the counterweight part includes a plurality of counterweight sub - zones.

[0093] In some embodiments, different counterweight sub - zones are connected in series with each other. Specifically, different counterweight sub - zones are interconnected, and a switch assembly for opening or closing the communication channel is provided between adjacent counterweight sub - zones.

[0094] Exemplarily, the counterweight part includes N counterweight sub - zones connected end to end, which are the first to the Nth counterweight sub - zones respectively. N - 1 solenoid valves are provided between the N counterweight sub - zones. The water inlet of the first counterweight sub - zone is connected to the water inlet pipe of the washing machine. Opening the first M (M is between 1 and N - 1) solenoid valves can make the first M counterweight intervals be connected, and counterweight fluid can be injected into these M counterweight intervals.

[0095] Furthermore, when the counterweight part is connected in series to the water inlet pipe or the drain pipe, each counterweight sub - zone is provided with a second water outlet, which is independently connected to the water inlet of the drum or the drain pipe. Each counterweight sub - zone is provided with a solenoid valve at the second water outlet to control the opening and closing of the second water outlet, or a three - way solenoid valve is provided to simultaneously control the on - off of the second water outlet and the water outlet. When only the first M counterweight intervals need to be filled with water, control the solenoid valves at the water outlets between the first M counterweight sub - zones to open, and close the solenoid valves at the water outlets between the subsequent counterweight sub - zones. Open the second water outlet of the Mth counterweight interval. In this way, when filling water or draining water, one or more of the multiple counterweight sub - zones can be filled with counterweight fluid simultaneously, thereby adjusting the total filling amount of the counterweight fluid and adjusting the total counterweight.

[0096] In some embodiments, different counterweight sub - zones are connected in parallel with each other. Specifically, different counterweight sub - zones are independent of each other. Each counterweight sub - zone is provided with an independent inlet and outlet, and an inlet valve and an outlet valve are independently provided. According to the filling amount of the counterweight fluid, the inlet valves of any number of counterweight sub - zones can be selected to be opened. Subsequently, according to the water inlet situation of the laundry treatment device and whether the counterweight part needs to drain water, any number of the outlet valves of the above - mentioned counterweight sub - zones can be selected to be opened.

[0097] [Embodiment 8]

[0098] This embodiment provides a control method for a laundry treatment device provided in the foregoing embodiment, including: before executing a laundry treatment program, injecting a counterweight fluid into the counterweight portion until it is not less than a set amount.

[0099] Exemplarily, for a washing machine, the laundry treatment program mainly refers to a program in which the drum rotates to wash, rinse, or spin-dry the laundry. During the above laundry treatment program, the motor runs, and the laundry in the drum moves, making it easier for the drum to vibrate or generate noise. Especially when spinning the laundry, the motor needs to reach a very high speed, and a larger counterweight is particularly needed to control the vibration and prevent the laundry treatment device from shifting or the like. Before executing the above laundry treatment program, water can be added to the counterweight portion during the water inlet process or during the drainage process after washing or rinsing to increase the counterweight.

[0100] Generally speaking, the set amount represents the minimum amount of counterweight fluid required for the current load. For some devices with relatively simple control, it can be set to directly fill the counterweight portion with water during water inlet or drainage. In this case, the volume of the counterweight portion can be set such that the amount of counterweight fluid corresponding to when the counterweight portion is full is greater than or equal to the amount of counterweight fluid required for the maximum load of the laundry treatment device, so as to ensure that the laundry treatment device operates under sufficient counterweight within the set load range.

[0101] In some embodiments, the set amount of the counterweight fluid injected into the counterweight portion is determined according to the load of the laundry treatment device. Further, the higher the load, the higher the counterweight required for the laundry treatment device to reduce vibration. Therefore, in this embodiment, the laundry treatment device determines the set amount of the counterweight fluid according to its own current load, and the load and the set amount are positively correlated.

[0102] Further, after the user adds laundry to the laundry treatment device, the laundry treatment device weighs the laundry and determines the set amount of the counterweight fluid according to the weighing result.

[0103] Further, in some embodiments, the counterweight fluid does not need to be discharged every time a laundry treatment program is executed. Therefore, after weighing the laundry each time, the laundry treatment device executes a counterweight detection program to detect the current amount of the counterweight fluid in the counterweight portion, and determines whether to supplement the counterweight fluid to the counterweight portion according to the detection result. Further, the timing of executing the counterweight detection program can be before each program operation of the laundry treatment device, or regularly, or after the laundry treatment device has run a set number of times.

[0104] Specifically, if it is detected that the current weight is greater than or equal to the set amount, it indicates that the counterweight is sufficient and there is no need to inject counterweight fluid into the counterweight part; if it is detected that the current weight is less than the set amount, it indicates that the counterweight is insufficient, and then counterweight fluid is added to the counterweight part until the set amount is reached. In some embodiments, if it is detected that the current weight is greater than or equal to the set amount, the excess counterweight fluid can also be discharged to reduce the amount of counterweight fluid to the set amount to achieve the best clothing treatment effect.

[0105] In some embodiments, especially when the counterweight fluid in the counterweight part is used sewage, in order to avoid generating odors, when the storage time of the counterweight fluid in the counterweight part reaches the set time, it will be forcibly discharged. Preferably, after the counterweight fluid is forcibly discharged, a cleaning program is also executed to introduce a small amount of clean water into the counterweight part to clean the cavity of the counterweight part.

[0106] Exemplarily, during the transportation of the clothing treatment device, its counterweight part is in an empty state to reduce the weight of the whole machine and lower the transportation cost. After arriving at the user's home and being installed, the clothing treatment device is started, and the control system executes the counterweight detection program. If it is detected that the current counterweight is insufficient, counterweight fluid is added to the counterweight part. Of course, it can also be to send a prompt to the customer for the customer to manually add it. After the clothing treatment device executes the clothing treatment program, the counterweight fluid in the counterweight part can be discharged, or it can be stored in the counterweight part for a long time and replenished when the counterweight is insufficient.

[0107] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0108] 1. The clothing treatment device and its control method provided by the present invention, by setting a counterweight part on the outer shell of the clothing treatment device, the counterweight fluid can be discharged to reduce the weight when moving the clothing treatment device. The structure is simple, effectively reducing the weight of the whole machine at the factory stage and lowering the transportation cost. After arriving at the user's home, when needed, counterweight fluid is injected into it to increase the weight of the clothing treatment device and improve its shock absorption effect. It is flexible and convenient to use, enhancing the user experience.

[0109] 2. The clothing treatment device and its control method provided by the present invention set a sandwich layer in the outer shell and set the counterweight part in the sandwich layer. The setting of pipelines and lines is more free, without considering avoiding the internal structure, and it is also more beautiful.

[0110] 3. The clothing treatment device and its control method provided by the present invention connect the counterweight part to the water system of the clothing treatment device, and further through pipeline connection, the counterweight part can be filled and drained as the clothing treatment device intakes and discharges water, and the control is more smooth and convenient. Using water as the counterweight fluid, the cost is low and it is easy to operate.

[0111] 4. The laundry treatment device and its control method provided by the present invention are such that the set amount of the counterweight fluid is related to the load of the laundry treatment device, and the most suitable counterweight is determined according to the load condition to achieve the best shock absorption and noise reduction effects.
