Description

[0002] At present, the washing machine has become an indispensable household appliance for every family, which can clean clothes, bedding and other daily necessities conveniently and quickly, and brings great convenience to people's life. During the use of the washing machine, the weight of the washing object needs to be weighed before water is added, and then the appropriate water quantity is determined according to the weight of the washing object. The existing pulsator washing machine usually adopts the method of motor weighing, which drives the load to rotate by controlling the motor, and monitors the comparison result of the motor current and the no-load rotation current, and obtains the load weight according to the conversion formula. This weighing method is affected by factors such as bearing resistance and eccentricity. For the full load washing condition of the pulsator washing machine, the weighing error is small, but for the weighing of small weight washing objects, the error is often large. Thus, the water quantity of the pulsator washing machine cannot be accurately corresponding to the washing object, which affects the washing effect and wastes resources. In the related art, a weighing sensor is installed between the shell and the washing drum of the pulsator washing machine to reduce the weighing error of the pulsator washing machine.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0004] The weighing method for reducing the weighing error of the pulsator washing machine in the related art has a long load time of the weighing sensor, and the weighing error becomes larger as the use time of the washing machine increases.

The upper part of the shell 100 is provided with a cover 600 which covers the shell 100, and the shell 100 and the cover 600 constitute a closed containing space, which ensures the operation safety of the pulsator washing machine during use and also prevents the washing water from splashing out. The cover 600 has a certain containing space inside, which can be used to install components such as a main control module and a display module. The lower part of the shell 100 is provided with a disc seat 700 which is used to support the shell 100, the disc seat 700 can play a role of isolating water vapor, and part of the components are also installed inside the disc seat 700. The lower part of the disc seat 700 is provided with a plurality of feet 800, which can support the entire upper component and also can be used to level the pulsator washing machine on the placement surface.

[0050] The embodiment of the present disclosure does not limit the number of the hangers 410 and the weighing assemblies, for the convenience of understanding, taking the number of the hangers 410 as four as an example, the four hangers 410 are respectively hung on the four corners of the upper part of the inner wall of the shell 100, and taking one group of the weighing assemblies 500 as an example, one of the hangers 410 is connected to the weighing assembly 500.

[0051] In some embodiments, the pulsator washing machine comprises a shell 100, a washing tub 200, a tub driving member 300, a suspension assembly and a weighing assembly 500. The shell 100 is defined as a containing space. The washing tub 200 is installed in the containing space and is used to carry and wash the articles to be washed. The suspension assembly is arranged between the washing tub 200 and the inner wall of the shell 100 and is used to suspend the washing tub 200. The suspension assembly comprises a hanger 410, one end of the hanger 410 is movably connected to the inner wall of the shell 100, and the other end is connected to the lower part of the washing tub 200. The weighing assembly 500 is used to detect the weight of the articles to be washed. The weighing assembly 500 comprises a weighing driving part and a detection part, the weighing driving part is arranged on the inner wall of the shell 100, the detection part is arranged between the hanger 410 and the inner wall of the shell 100, and the weighing driving part and the detection part are in transmission connection. The weighing driving part can drive the detection part to switch between a load state in which the detection part is subjected to the pressure applied by the hanger 410 and a non-load state in which the detection part is unloaded from the pressure applied by the hanger 410.

[0052] The washing machine provided by the embodiment of the present disclosure can keep good weighing precision for a long time. The washing machine provided by the embodiment of the present disclosure comprises a shell 100, a washing tub 200, a suspension assembly and a weighing assembly 500. The shell 100 defines a containing space, and the washing tub 200 is installed in the containing space and used to carry and wash articles to be washed. The suspension assembly is used to suspend the washing tub 200 in the containing space in the shell 100. The suspension assembly comprises a hanger rod 410, one end of the hanger rod 410 is movably connected to the inner wall of the shell 100, and the other end is connected to the lower part of the washing tub 200, so that the washing tub 200 is stably suspended in the shell 100. The weighing assembly 500 is arranged between the suspension assembly and the inner wall of the shell 100 and is used to detect the weight of the articles to be washed. The weighing assembly comprises a weighing driving part and a detection part. The weighing driving part in the weighing assembly can drive the detection part to switch between a loaded state in which the detection part is subjected to the pressure applied by the hanger rod 410 and an unloaded state in which the detection part is not subjected to the pressure applied by the hanger rod 410, thereby reducing the loading time of the detection part, so that the washing machine can keep good weighing precision for a long time.

[0053] Optionally, the weighing driving part drives the detection part to rise, so that the detection part is in the loaded state in which the detection part is subjected to the pressure applied by the hanger rod 410 and is used to detect the tension borne by the hanger rod 410; or the weighing driving part drives the detection part to descend, so that the detection part is in the unloaded state in which the detection part is not subjected to the pressure applied by the hanger rod 410.

[0054] In this way, the weighing assembly 500 comprises the weighing driving part, the detection part and a main control part. One end of the detection part is connected to the weighing driving part, and the other end is connected to the hanger rod 410. When the washing machine needs to be weighed, the weighing driving part drives the detection part to rise, so that the detection part is in the loaded state in which the detection part is subjected to the pressure applied by the hanger rod 410 and is used to detect the tension borne by the hanger rod 410. When the washing machine does not need to be weighed, the weighing driving part drives the detection part to descend, so that the detection part is in the unloaded state in which the detection part is not subjected to the pressure applied by the hanger rod 410.

[0055] Optionally, the weighing driving part comprises a weighing driving piece 510 and a driving shaft 520. The weighing driving piece 510 is fixedly installed on the inner wall of the shell 100. One end of the driving shaft 520 is connected to the weighing driving piece 510, and the other end is connected to the detection part. The weighing driving piece 510 drives the driving shaft 520 to rotate and drive the detection part to rise to bear the pressure applied by the hanger rod 410, or the weighing driving piece 510 drives the driving shaft 520 to rotate and drive the detection part to descend to unload the pressure applied by the hanger rod 410.

[0056] The weighing driving part comprises a weighing driving member 510 and a driving shaft 520. The weighing driving member 510 is fixedly installed on the inner wall of the shell 100, the first end of the driving shaft 520 is connected to the weighing driving member 510, and the second end is drivingly connected to the detection part. In this way, the weighing driving member 510 can drive the driving shaft 520 to rotate to drive the detection part to detect the tension of the boom 410. For example, the detection part is lifted by forward rotation of the weighing driving member 510, and the detection part is lowered by reverse rotation of the weighing driving member 510. The forward rotation of the weighing driving member 510 drives the driving shaft 520 to rotate to drive the detection part to rise to load the pressure applied by the boom 410, so as to detect the tension of the boom 410, and the reverse rotation of the driving shaft 520 drives the driving shaft 520 to drive the detection part to descend to unload the pressure applied by the boom 410, so as to be in a non-loaded state.

[0057] Specifically, the weighing driving member 510 can be a driving motor. The inner wall of the shell 100 is provided with a support 511, and the weighing driving member 510 is installed on the support 511.

[0058] Optionally, the detection part comprises a first support plate 530, a second support plate 540 and a detection sensor 550. The first support plate 530 is drivingly arranged on the driving shaft 520 of the weighing driving part. The second support plate 540 is arranged on the boom 410. The detection sensor 550 is arranged between the first support plate 530 and the second support plate 540. Under the driving of the weighing driving part, the first support plate 530 can move upward to drive the detection sensor 550 to rise and synchronously drive the second support plate 540 to rise, so that the tension of the boom is applied to the second support plate 540, so that the detection part is loaded with the pressure applied by the boom 410, and is used for detecting the tension of the boom 410, or under the driving of the weighing driving part, the first support plate 530 moves downward to drive the detection sensor 550 to descend to unload the pressure applied by the boom 410.

[0059] In this way, the detection part comprises the first support plate 530, the second support plate 540 and the detection sensor 550. The first support plate 530 is arranged on the lower part of the driving shaft 520, the second support plate 540 is arranged on the boom 410, and the detection sensor 550 is arranged between the first support plate 530 and the second support plate 540. In this way, the detection sensor 550 can be used as a force arm, so that the detection sensor 550 can detect the load with higher precision. The weighing driving member 510 drives the driving shaft 520 to rotate, and drives the first support plate 530, the detection sensor 550 and the second support plate 540 to move upwards, so that the second support plate 540 and the boom 410 generate a force, and the tension of the boom 410 is detected. For example, the weighing driving member 510 drives the driving shaft 520 to rotate in the forward direction, the first support plate 530 moves upwards and drives the detection sensor 550 and the second support plate 540 to move upwards, so that the detection sensor 550 is loaded with the pressure applied by the boom 410, and the detection sensor 550 detects the tension of the boom 410. Alternatively, the weighing driving member 510 drives the driving shaft 520 to rotate in the reverse direction, the first support plate 530 moves downwards and drives the detection sensor 550 and the second support plate 540 to move downwards, so that the detection sensor 550 is unloaded with the pressure applied by the boom 410.

[0060] Specifically, the first support plate 530 further comprises a reinforcing plate 523 arranged on the lower part of the first support plate 530. In this way, the strength of the first support plate 530 is better.

[0061] Optionally, the detection sensor 550 comprises a load sensor, and the load sensor comprises an elastic deformation detection part and a signal transmission part arranged on the elastic deformation detection part. The first end of the elastic deformation detection part is fixedly connected to the first support plate 530, and the second end of the elastic deformation detection part is fixedly connected to the second support plate 540. When the detection part is loaded with the pressure applied by the boom 410, the elastic deformation detection part deforms under the action of the pressure applied by the boom 410, and the signal transmission part obtains the deformation amount of the elastic deformation detection part, and further obtains the pressure applied by the boom 410.

[0062] Optionally, the elastic deformation detection part comprises a deformation block, and the signal transmission part comprises a deformation sheet. The deformation sheet is arranged (for example, pasted) on the side of the deformation block. The first end of the deformation block is fixedly connected to the upper surface of the first support plate 530, and the second end of the deformation block is fixedly connected to the lower surface of the second support plate 540. The deformation sheet is arranged on the deformation block. When the detection part is loaded with the pressure applied by the boom 410, the deformation block deforms under the action of the pressure applied by the boom 410, and the deformation sheet obtains the deformation amount of the deformation block, so as to obtain the tension of the boom 410.

[0063] In this way, the first support plate 530 and the second support plate 540 are fixedly connected through the deformation block of the detection sensor 550, so that the first support plate 530 and the second support plate 540 can be driven to move together under the driving of the driving part. When the detection part is loaded with the pressure applied by the boom 410, the tension of the boom 410 acts on the upper surface of the second support plate 540, so that the deformation block of the detection sensor 550 is deformed, and the deformation piece obtains the deformation amount of the deformation block, thereby obtaining the tension of the boom 410. The deformation block is electrically connected to the weighing controller of the impeller washing machine. When the weighing controller controls the weighing driving part to drive the detection part to be in a load state of the pressure applied by the load boom 410, the deformation piece obtains the deformation amount of the deformation block, and transmits the deformation amount to the weighing controller. The weighing controller obtains the tension of the boom 410 according to the deformation amount, thereby obtaining the weight of the laundry.

[0064] Optionally, the weighing controller is configured to obtain a first weighing value according to the tension of the boom obtained by the detection part. According to the first weighing value, the weight of the laundry is obtained.

[0065] Optionally, the calculation formula of the weight of the laundry is: W=W1*n-W0. Wherein, W is the weight of the laundry, W1 is the first weighing value, W0 is the weight of the known components of the impeller washing machine, and n is the number of booms.

[0066] Specifically, taking a group of weighing assemblies 500 as an example, the number of booms 410 is 4. The detection sensor 550 obtains the tension of one boom 410, and the first weighing value is obtained through the conversion of the weighing controller. Then, the first weighing value is multiplied by four and subtracted by the weight of the known components of the impeller washing machine, thereby obtaining the weight of the laundry. In this way, the weight of the detection part is smaller, and the detection load precision of the detection part is higher.

[0067] Optionally, the lower part of the driving shaft 520 includes a threaded segment 521. The first support plate 530 is provided with a threaded hole 531. The first support plate 530 is arranged on the threaded segment 521 through the threaded hole 531, and under the rotary driving of the driving shaft 520 of the weighing driving part, the first support plate 530 can move along the driving shaft 520 to realize the rising or falling.

[0068] In this way, the threaded section 521 is arranged at the lower part of the driving shaft 520, the first supporting plate 530 is provided with the threaded hole 531, and the first supporting plate 530 is arranged on the threaded section 521 through the threaded hole 531. In this way, when the weighing driving member 510 drives the driving shaft 520 to rotate, the second supporting plate 540 cannot rotate but can only move upward or downward due to the resistance of the boom 410 to the second supporting plate 540 in the horizontal direction under the action of the threaded section 521 and the threaded hole 531. In this way, the first supporting plate 530, the detection sensor 550 and the second supporting plate 540 can all move upward or downward, so as to realize the rising or falling of the detection sensor. Specifically, the stopper 522 is arranged at the end of the threaded section 521, so as to prevent the first supporting plate 530 from being separated from the driving shaft 520 during the movement, thereby affecting the action of the entire weighing assembly 500.

[0069] Optionally, the pulsator washing machine further comprises a suspension structure 110. The suspension structure 110 is arranged on the inner wall of the upper part of the shell 100, and the suspension structure 110 comprises a suspension opening 111. The boom 410 is movably arranged in the suspension opening 111.

[0070] In this way, the suspension structure 110 is arranged on the inner wall of the upper part of the shell 100, so that the suspension assembly can be more stably and conveniently suspended on the inner wall of the upper part of the shell 100. The boom 410 is movably arranged in the suspension opening 111, so that the movement of the boom 410 is not limited, and the detection of the tension borne by the boom 410 by the detection part is more accurate. Specifically, the lug 112 is further arranged at the suspension opening 111, so as to increase the strength of the suspension opening 111 and reduce the noise during the operation of the pulsator washing machine.

[0071] Optionally, the suspension assembly further comprises a first blocking member 420 and a second blocking member 430. The first blocking member 420 is arranged at the upper part of the boom 410 and close to the second supporting plate 540. The second blocking member 430 is arranged at the upper end of the boom 410 and above the suspension structure 110. The second supporting plate 540 is movably arranged in the boom 410. When the detection part rises, the second supporting plate 540 rises and contacts the first blocking member 420 to load the pressure applied by the boom 410 on the detection sensor, or when the detection part falls, the second supporting plate 540 is separated from the first blocking member 420 to unload the pressure applied by the boom 410 on the detection sensor.

[0072] The suspension assembly further comprises a first blocking member 420 and a second blocking member 430 arranged on the hanger 410. The first blocking member 420 is arranged close to the second support plate 540 and is configured to interact with the second support plate 540 to enable the detection unit to bear the pressure applied by the hanger 410. The second blocking member 430 is arranged on the upper end of the hanger 410 and is located above the suspension structure 110, so that the hanger 410 can be movably suspended on the suspension structure 110.

[0073] Specifically, when the drum washing machine needs to be weighed, the weighing drive 510 drives the drive shaft 520 to rotate to drive the first support plate 530, the detection sensor 550 and the second support plate 540 to move upward, and the second support plate 540 interacts with the first blocking member 420 to enable the detection sensor 550 to bear the pressure applied by the hanger 410. When the second blocking member 430 is supported to be separated from the suspension structure 110, it indicates that the hanger 410 is completely lifted, and the pressure borne by the detection unit no longer changes, which indicates that the weight of the drum washing machine can be obtained. For example, the weighing drive 510 drives the drive shaft 520 to rotate forward, the first support plate 530 moves upward to drive the detection sensor and the second support plate 540 to rise to contact the first blocking member 420 to enable the detection sensor to bear the pressure applied by the hanger 410, so that the detection sensor detects the tension borne by the hanger 410. Alternatively, the weighing drive 510 drives the drive shaft 520 to rotate reversely, the first support plate 530 moves downward to drive the detection sensor and the second support plate 540 to descend to separate from the first blocking member 420 to enable the detection sensor to unload the pressure applied by the hanger 410.

[0074] Optionally, the size of the suspension opening 111 is a first length. The maximum cross-sectional length of the second blocking member 430 is a second length. The cross-sectional length of the hanger 410 is a third length. The first length is smaller than the second length and larger than the third length.

[0075] Optionally, the size of the suspension opening 111 is a first length. The maximum cross-sectional length of the second blocking member 430 is a second length. The cross-sectional length of the hanger 410 is a third length. The first length is smaller than the second length and larger than the third length.

[0076] Specifically, the shape of the second blocking member 430 is not limited, and the maximum cross-sectional shape of the second blocking member 430 can be circular or elliptical.

[0077] Optionally, the second support plate 540 is provided with a through hole 541, and the second support plate 540 is arranged on the hanger 410 through the through hole 541. The diameter of the through hole 541 is a fourth length. The maximum cross-sectional length of the first blocking member 420 is a fifth length. The fourth length is larger than the third length and smaller than the fifth length.

[0078] Thus, the second support plate 540 is provided with a through hole 541, the second support plate 540 is arranged to pass through the through hole 541 of the hanger 410, and the diameter of the through hole 541 is greater than the cross-sectional length of the hanger 410 and less than the maximum cross-sectional length of the first blocking piece 420. In this way, the second support plate 540 can move in the vertical direction of the hanger 410, and when interacting with the first blocking piece 420, the pressure on the hanger 410 can be detected. Further, after the second support plate 540 is driven away from the first blocking piece 420 by the weighing driving piece 510, the hanger 410 is not in contact with the second support plate 540, so that the detection sensor 550 is not forced in the non-weighing state.

[0079] Specifically, the shape of the first blocking piece 420 is not limited, and the maximum cross-section of the first blocking piece 420 can be circular or elliptical.

[0080] Optionally, the first blocking piece 420 is detachably arranged at the upper portion of the hanger 410. The first blocking piece 420 and the hanger 410 can be connected by threads.

[0081] Optionally, the second blocking piece 430 is detachably arranged at the upper end of the hanger 410. The second blocking piece 430 and the hanger 410 can be connected by threads.

[0082] Optionally, the pulsator washing machine further comprises a weighing controller. When it is necessary to weigh the to-be-washed articles, the weighing controller controls the weighing driving part to drive the detection part to be in a load state in which the pressure applied by the load hanger 410 is detected, so as to detect the tension borne by the hanger 410, or when it is not necessary to weigh the to-be-washed articles, the weighing controller controls the weighing driving part to drive the detection part to be in an unload state in which the pressure applied by the load hanger 410 is not detected.

[0083] For example, in combination with Figure 3 and Figure 4 As shown, when the pulsator washing machine does not need to weigh the to-be-washed articles, the weighing assembly 500 and the suspension assembly are both in an initial reset state. As shown in Figure 3 , the weighing driving piece 510 is not running, the first support plate 530 is located at the lower end of the threaded section 521 of the driving shaft 520, the second support plate 540 is a certain distance away from the first blocking piece 420, the second blocking piece 430 at the end of the hanger 410 is completely in contact with the suspension opening 111 of the suspension structure 110, and the detection sensor 550 is in an undetected state. For the case that the second support plate 540 is movably arranged on the hanger 410 through the through hole and the diameter of the through hole is greater than the cross-sectional length of the hanger 410, the hanger 410 is located at the center position of the through hole 541 of the second support plate 540 and is not in contact with the inner wall of the through hole 541, as shown in Figure 4 .

[0084] As shown in Figure 5 and Figure 6 When the drum washing machine needs to weigh the laundry, the weighing controller controls the weighing driving part to drive the detection part to be in a load state of the pressure applied by the load hanger 410, so as to detect the tension applied by the hanger 410, thereby obtaining the weight of the laundry.

[0085] Alternatively, the weighing controller controls the weighing driving part to be forward driven, the first support plate 530 moves upward to drive the detection sensor 550 to rise and synchronously drive the second support plate 540 to rise, so that the tension applied by the hanger 410 is applied to the second support plate 540, thereby making the detection part load the pressure applied by the hanger, for detecting the tension applied by the hanger.

[0086] In the case that the second support plate 540 is movably arranged on the hanger 410 through the through hole and the diameter of the through hole is greater than the cross-sectional length of the hanger 410, in combination with Figure 6 As shown in Figure 5 the weighing driving part is forward driven, the threaded hole 531 on the first support plate 530 interacts with the threaded section 521 of the driving shaft 520, so that the second support plate 540 moves a distance in the horizontal direction and contacts with the inner wall of one side of the through hole 541 on the second support plate 540. Under the resistance of the hanger 410, the second support plate 540 cannot be horizontally rotated, but can only start to move upward. In combination with Figure 5 the weighing driving part is forward driven, the threaded hole 531 on the first support plate 530 interacts with the threaded section 521 of the driving shaft 520 of the weighing driving part, under the resistance of the hanger 410, so that the first support plate 530 moves upward, and in turn drives the detection sensor 550 and the second support plate 540 to move upward. When the second support plate 540 starts to contact the first blocking piece 420, under the action of the first blocking piece 420, the hanger 410 is lifted upward. When the second blocking piece 430 completely leaves the suspension opening 111 of the suspension structure 110, it indicates that the weight in the drum washing machine has been weighed, and at this time the detection sensor 550 detects the pressure applied by the hanger 410, thereby obtaining the weight of the laundry.

[0087] As shown in Figure 7 and Figure 8 When the drum washing machine weighing is completed, the weighing controller controls the weighing driving part to drive the detection part to be in an unload state of the pressure applied by the hanger 410. The weighing driving part 510 is reversely rotated, and in turn the suspension assembly and the weighing assembly 500 return to the initial position.

[0088] Optionally, the weighing controller controls the weighing drive to reverse drive, the first support plate 530 moves downward to drive the detection sensor 550 to descend and synchronously drive the second support plate 540 to descend, so that the second support plate 540 is separated from the first blocking piece 420 to unload the pressure applied by the boom 410 on the detection sensor 550.

[0089] In combination Figure 8 As shown, in the case that the second support plate 540 is movably arranged on the boom 410 through the through hole and the diameter of the through hole is greater than the cross-sectional length of the boom, the weighing drive 510 reversely rotates, and in the process that the second support plate 540 returns to the initial position, the boom 410 is in contact with the inner wall of the other side of the through hole 541 on the second support plate 540, and the detection sensor 550 is in a loaded state. For this case, the controller is further configured to: in the case that the weighing drive is reversely driven to the first support plate 530 returns to the initial height, control the weighing drive to forward drive to a set angle, so that the second support plate 540 reversely moves a certain distance in the horizontal direction, and then the boom 410 is in the center position of the through hole 541 on the second support plate 540. So that the boom 410 is not in contact with the inner wall of the through hole 541, so that the detection sensor 550 is in an undetected state, and ensures that it is not affected by the boom in the undetected state, and maintains the non-loaded state. In this way, the load time of the detection sensor 550 can be reduced, so that the drum washing machine can maintain good detection accuracy for a long time.
