Description

Technical Field

[0001] The invention belongs to the field of washing machines, and in particular relates to a washing machine. Background Art

[0002] A washing machine is designed as a device for washing clothes by using electricity, and generally includes: a tub for containing washing water; a rotating tub rotatably installed inside the tub; a pulsator rotatably installed at the bottom of the rotating tub; a motor and a clutch configured to rotate the rotating tub and the pulsator. When the rotating tub and the pulsator rotate in a state where clothes and detergent are introduced into the rotating tub, the pulsator stirs the washing water together with the clothes introduced into the rotating tub, thereby removing stains from the clothes.

[0003] In order to increase the washing capacity of the washing machine, a larger rotating tub is required, that is, the height or diameter of the rotating tub needs to be increased. If the rotating tub has a larger size, the outer tub accommodating the rotating tub and the housing accommodating the outer tub also need to be increased as the rotating tub increases.

[0004] For families with relatively smaller residential areas, the space for placing washing machines is even smaller. It is not realistic to increase the inner drum by adding an outer drum and a casing. How to increase the capacity of the rotating drum without increasing the casing of the washing machine has become a major problem that has troubled designers.

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

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing machine. By setting a water collecting structure, water is discharged into the water collecting structure during drainage and dehydration. During washing and rinsing, the inner barrel is a water barrel, so that no outer barrel is provided outside the inner barrel. The movable space of the inner barrel is increased, and the possibility of barrel collision is reduced. At the same time, due to the increase in the movable space of the inner barrel mouth, the volume of the inner barrel can be increased by increasing the diameter of the inner barrel without increasing the volume of the washing machine shell, thereby achieving effective capacity expansion. By making the upper edge of the water collecting structure lower than the upper opening of the inner barrel, the volume of the water collecting structure is expanded and the side wall of the water collecting structure does not hinder the shaking of the inner barrel, thereby reducing the probability of collision between the inner barrel and the water collecting structure.

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

[0008] A washing machine comprises a washing machine housing, an inner barrel arranged in the washing machine housing and a driving device for driving the inner barrel to rotate, wherein the inner barrel is a water storage tub; and further comprises a shock absorbing structure and a water collecting structure, wherein the water collecting structure is installed in the washing machine housing through the shock absorbing structure, and the water collecting structure is located outside the inner barrel, and during dehydration and / or drainage, water discharged from the inner barrel is discharged via the water collecting structure.

The suspension rod passes through the mounting portion and is suspended on the washing machine housing through the upper fixing seat. The shock absorption and buffering device is sleeved on the suspension rod, located between the mounting portion and the shock absorption sleeve, and covers the upper surface of the shock absorption sleeve.

[0015] The shock absorption structure includes a support shock absorber. One end of the support shock absorber is connected to the washing machine housing, and the other end is connected to the water collecting structure, supporting the water collecting structure and the inner barrel in the washing machine housing.

[0016] Preferably, the support shock absorber is inclined, and the end connected to the water collecting structure is located on the bottom wall of the water collecting structure.

[0017] The shock absorption structure further includes a horizontal shock absorber. The horizontal shock absorber is horizontally arranged between the water collecting structure and the washing machine housing and is respectively connected to the water collecting structure and the washing machine housing to reduce the vibration of the inner barrel and the water collecting structure in the horizontal direction.

[0018] Preferably, the horizontal shock absorber includes a shock absorption mechanism and a first shock absorption connecting member and a second shock absorption connecting member connected to the shock absorption mechanism. The first shock absorption connecting member and the second shock absorption connecting member are respectively connected to the side wall of the water collecting cavity and the inner wall of the washing machine housing.

[0019] The washing machine further includes a drainage structure for discharging the water in the water collecting structure out of the washing machine. The water inlet end of the drainage structure is communicated with the water collecting structure, and the water outlet end extends outside the washing machine.

[0020] Preferably, the whole drainage structure is located below the water collection structure, and the drainage structure is in a normally open state;

[0021] More preferably, the drainage structure includes a drainage channel. The water inlet end of the drainage channel is communicated with the water collection structure. The whole drainage channel is located below the water inlet end of the drainage channel, and the drainage channel is in a normally open state.

[0022] The drainage structure includes a drainage channel and a control mechanism for controlling the on / off of the drainage channel of the drainage structure. The control mechanism is arranged on the drainage channel and communicated with the drainage channel. The washing machine further includes a main control device. The control mechanism is electrically connected to the main control device 900 to control the opening / closing of the control mechanism, so as to realize the on / off of the drainage channel;

[0023] Preferably, the drainage structure further includes a detection device for detecting the water level height in the water collection structure. The detection device is electrically connected to the main control device. The detection device detects the water level in the water collection structure and transmits it to the main control device. The main control device controls the opening / closing of the control mechanism according to the detection result detected by the detection device;

[0024] More preferably, the detection device is a water level sensor or a pressure sensor arranged in the water collection structure, and the control mechanism is an electromagnetic valve.

[0025] It further includes a detected end and a detection end for detecting the position of the detected end. The detected end and the detection end are respectively arranged on the inner tub and the washing machine housing. The detection end is electrically connected to the main control device,

[0026] The detection end detects the distance between the detected end and the detection end, and the control device controls the washing machine according to the detection result of the detection end;

[0027] Preferably, the detected end is a magnetic part capable of generating a magnetic field, and the detection end is a magnetic sensitive element. When the magnetic part approaches the magnetic sensitive element, the magnetic sensitive element transmits a detection signal to the main control device, and the main control device controls the washing machine to act.

[0028] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: By setting the water collection structure, during drainage and dehydration, the water is drained into the water collection structure. During washing and rinsing, the inner tub serves as the water storage tub, realizing that there is no outer tub outside the inner tub, increasing the movable space of the inner tub, reducing the possibility of barrel collision. At the same time, since the movable space at the inner tub opening is increased, the volume can be effectively expanded by increasing the diameter of the inner tub; By making the upper opening of the water collection cavity located between the bottom wall of the inner tub and the inner tub opening, both the volume of the water collection cavity is enlarged and the side wall of the water collection cavity does not interfere with the swaying of the inner tub opening, reducing the probability of collision between the inner tub opening and the water collection cavity.

[0040] 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 reference to specific embodiments. Detailed implementation manners

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

[0042] Embodiment 1

[0043] As Figures 1-6 shown, a washing machine includes a washing machine housing 100, an inner tub 200 disposed within the washing machine housing 100, and a driving device 300 for driving the inner tub 200 to rotate. The inner tub 200 is a water storage tub, and further includes a shock-absorbing structure and a water collecting structure. The water collecting structure is installed within the washing machine housing 100 through the shock-absorbing structure, and the water collecting structure is located outside the inner tub.

[0044] During dehydration and / or drainage, the water discharged from the inner tub 200 is discharged via the water collecting structure.

[0045] By setting up a water collecting structure, during washing / rinsing, the inner tub 200 serves as the water receiving tub. During dehydration and / or draining, the water collecting structure collects the water discharged from the inner tub 200. Such a cooperation eliminates the outer tub. Without changing the volume of the washing machine housing 100, the available space of the inner tub 200 within the washing machine housing 100 is increased. The purpose of expanding the volume of the inner tub 200 can be achieved by increasing the diameter of the inner tub 200.

[0046] Through the shock absorption effect of the shock absorption structure, the vibrations of the inner tub 200 and the water collecting structure are reduced, preventing the inner tub 200 and the water collecting structure or the washing machine housing 100 from colliding, and reducing the possibility of damage to the inner tub 200, the water collecting structure, and the washing machine housing 100.

[0047] Furthermore, the water collecting structure includes a water collecting cavity 400 with an upper opening. The output shaft 303 of the driving device 300 passes through the water collecting cavity 400 and is connected to the inner tub 200. The upper opening of the water collecting cavity is arranged lower than the inner tub opening of the inner tub.

[0048] Furthermore, the inner tub 200 is arranged within the water collecting cavity 400. The output shaft 303 of the driving device 300 passes through the bottom wall of the water collecting cavity 400 and is connected to the inner tub 200 to drive the inner tub 200 to rotate. The output shaft 303 and the water collecting cavity can be hermetically connected through a bearing.

[0049] In current washing machines, an outer tub is generally arranged outside the inner tub 200, and the outer tub serves as the water receiving tub. During the laundry process, the output shaft 303 of the driving device 300 rotates to drive the inner tub 200 to rotate. When the rotational speed of the inner tub 200 reaches near the resonance point, it is very easy to cause strong shaking of the inner tub 200, and it is easy to lead to a collision between the inner tub 200 and the outer tub. Therefore, a safety distance needs to be set between the inner tub and the outer tub, which will limit the volume of the inner tub. Moreover, the collision between the inner tub and the outer tub mainly occurs at the inner tub opening part of the inner tub 200, and there is basically no collision at the lower part.

[0050] Based on the above considerations, in the present invention, no outer tub is arranged outside the inner tub 200, eliminating the space for installing the outer tub and the safety distance between the inner tub and the outer tub. Only the safety distance between the inner tub and the washing machine housing needs to be considered. By setting the edge of the upper opening to be higher than the bottom wall of the inner tub 200 and not higher than the inner tub opening, the upper edge of the water collecting structure is lower than the inner tub opening, increasing the space near the position (inner tub opening) where collisions are most likely to occur, making it difficult for the inner tub opening to collide with the washing machine housing, and achieving the purpose of expanding the capacity by appropriately increasing the diameter of the inner tub 200.

[0051] Further, the water collection structure includes a mounting plate 500 and a water retaining rib 501 disposed on the mounting plate 500. The mounting plate 500 and the water retaining rib 501 enclose the water collection cavity 400. The upper edge of the water retaining rib 501 is not higher than the inner barrel opening of the inner barrel 200. Preferably, the upper edge of the water retaining rib 501 is not higher than half of the height of the inner barrel 200. The mounting plate 500 and the water retaining rib 501 enclose the water collection cavity 400, which has a simple structure and is convenient for processing and forming.

[0052] When the rotation speed of the inner barrel 200 approaches the resonance point, since the shock absorption mechanism is connected to the water collection structure, the closer the inner barrel 200 is to the opening, the more violently it shakes. After the inner barrel 200 is enlarged, the water holding capacity of the inner barrel 200 increases. To save laundry time, the faster the drainage speed, the better. By setting the upper edge of the water retaining rib 501 not higher than half of the inner barrel 200, when the laundry water flows into the water collection cavity at a relatively fast speed, due to the relatively high setting of the water retaining rib 501 and the large water holding capacity, the laundry water is quickly discharged without overflowing, effectively preventing the laundry water from overflowing from the water collection structure to the electrical components at the bottom of the washing machine housing 100, and reducing the possibility of damage to the electrical components (such as the power board, etc.). The water retaining rib 501 is disposed on the upper plate surface of the mounting plate 500, and the water collection cavity is located in the middle of the mounting plate 500, making the center of gravity of the water collection device easier to coincide with the center and reducing the offset.

[0053] Further, a water collection channel communicating with the inner barrel is also provided on the inner barrel. The water collection channel communicates with the water collection cavity; when the washing machine is dehydrating, the water thrown out passes through the water collection channel into the water collection cavity and is discharged through the water collection structure.

[0054] The water collection channel includes a dehydration port 201 provided at the upper part of the barrel wall of the inner barrel 200 and a dehydration water channel 202 communicating with the dehydration port 201. The water outlet 203 of the dehydration water channel 202 is provided above the upper opening of the water collection cavity 400 to make the water collection channel communicate with the water collection cavity. Both the dehydration port 201 and the dehydration water channel 202 are multiple. Each dehydration port 201 corresponds to a corresponding dehydration water channel 202 respectively, or multiple dehydration ports 201 correspond to one dehydration water channel 202. When the washing machine executes the drying program, the water thrown out due to the centrifugal action of the inner barrel 200 enters the dehydration water channel 202 through the dehydration port 201 and is discharged into the water collection cavity 400 through the water outlet 203 of the dehydration water channel 202, preventing the water from overflowing everywhere.

[0055] The water outlet 203 of the dehydration water channel 202 is arranged in the water collection cavity 400. By connecting the water outlet 203 with the water collection structure, during dehydration, water enters the dehydration water channel 202 through the dehydration opening 201 and then is discharged through the water outlet 203 into the water collection cavity 400, preventing water from overflowing; the water outlet 203 is arranged in the water collection cavity 400, and the water discharged from the water outlet 203 directly falls into the water collection cavity 400. This structure is simpler, without the need to add other additional components, and has a better water collection effect. The water outlet is an opening formed at the lower part of the inner tub.

[0056] Furthermore, the inner tub 200 further includes a drain opening 204 for draining the water in the inner tub 200 into the water collection cavity 400 during drainage and / or dehydration. A blocking device 205 is arranged between the drain opening 204 and the water collection cavity 400. The blocking device 205 opens the drain opening 204 during drainage and / or dehydration, and a large amount of water in the inner tub 200 is discharged through the drain opening 204. During laundry, the drain opening 204 is blocked to retain the water in the inner tub 200 for laundry.

[0057] Furthermore, the drain opening 204 is arranged at the bottom of the inner tub, and the blocking device 205 is arranged below the drain opening 204. By arranging the drain opening 204, during dehydration and / or drainage, the blocking device 205 opens the drain opening 204 to directly discharge the water in the inner tub 200 into the water collection structure, and the water blocking rib 501 blocks the laundry water to prevent the laundry water from overflowing; when doing laundry, the blocking device 205 blocks the drain opening 204 to keep the water in the inner tub 200 for laundry. The washing machine can be a pulsator washing machine.

[0058] The blocking device 205 includes a valve plug 205-1 and an electromagnetic device 205-2 arranged under the valve plug 205-1. The electromagnetic device 205-2 is electrically connected to the control device of the washing machine. When the washing machine is in the laundry state, the valve plug 205-1 blocks the drain opening 204 to prevent the water in the inner tub 200 from being discharged. When the washing machine is in the drainage or dehydration state, the electromagnetic device 205-2 controls the valve plug 205-1 to move downward to open the drain opening 204 and discharge the laundry water into the water collection structure.

[0059] A positioning device is provided on the mounting plate 500, and a mating portion matching the positioning device is provided on the bottom wall of the inner tub 200. The mating portion can be a positioning groove. When dehydrating and / or spin-drying, the positioning device disengages from the mating portion, and the inner tub 200 rotates with the output shaft 303. When the washing machine is in the washing state, the positioning device cooperates with the mating portion to clamp the inner tub 200 on the mounting plate 500. The valve plug 205-1 is exactly opposite to the drain port 204 to block the drain port 204 and prevent the water in the inner tub 200 from draining. The output shaft drives the agitator in the inner tub to rotate. Further, the mounting plate 500 is disposed between the inner tub 200 and the driving device 300, and the driving device 300 is fixedly installed at the lower part of the mounting plate 500. By disposing the mounting plate 500 between the inner tub 200 and the driving device 300, on the one hand, the water in the inner tub 200 can flow down by its own weight and automatically flow into the water collecting structure. On the other hand, the mounting plate 500 is disposed above the driving device 300 to isolate the washing water from the driving device 300 and prevent damage to the driving device 300 caused by the washing water.

[0060] The driving device 300 includes a motor 301. A speed reduction and clutch device 302 is provided above the motor 301. The lower part of the mounting plate 500 is fixedly connected to the speed reduction clutch or the housing of the motor 301.

[0061] The connection manner between the mounting plate 500 and the driving device 300 can also be: The mounting plate 500 and the output shaft 303 of the driving device 300 are connected by a bearing.

[0062] Further, the output shaft 303 of the speed reduction clutch passes through the mounting plate 500 and is connected to the inner tub 200 to drive the rotation of the inner tub 200. The mounting plate 500 and the output shaft 303 of the driving device 300 are connected by a bearing.

[0063] Embodiment Two:

[0064] As Figures 1-6 shown, this embodiment further limits Embodiment One. The shock absorption structure includes a suspension shock absorber 600. One end of the suspension shock absorber 600 is connected to the upper part of the washing machine housing 100, and the other end is connected to the water collecting structure to reduce the vibration of the inner tub and the water collecting structure.

[0065] The output shaft 303 of the driving device 300 passes through the bottom wall of the collection chamber 400 and is connected to the inner tub 200, so that the driving device 300, the inner tub 200 and the water collecting structure form an inner tub assembly.

[0066] One end of the suspension shock absorber 600 is connected to the upper part of the washing machine housing 100, and the other end is connected to the water collection structure. When the motor drives the inner barrel to rotate and the rotation speed of the inner barrel reaches near the resonance point, violent shaking occurs, driving the overall shaking of the inner barrel assembly. By connecting the suspension shock absorber to the water collection structure, the shaking of the water collection mechanism is reduced, thereby reducing the vibration of the inner barrel assembly. It is also possible that the suspension shock absorber suspends the inner barrel assembly in the washing machine housing to achieve a better shock absorption effect.

[0067] The suspension shock absorber includes a suspension rod 602, an upper fixing seat, and a shock absorption sleeve 2 at the lower end of the suspension rod. A shock absorption unit 601 for generating a damping force is provided in the shock absorption sleeve 2. An installation part is provided on the water collection structure, preferably on the side wall. The shock absorption sleeve is placed below the installation part. One end of the suspension rod 602 passes through the installation part 701 and is fixed to the washing machine housing 100 through the upper fixing seat. The shock absorption sleeve 2 is located below the installation part.

[0068] As Figures 7-8 shown, an installation part 701 for hanging the shock absorption sleeve 2 is provided at the lower part of the water collection structure of the washing machine. The shock absorption sleeve 2 is placed below the installation part 701. The suspension rod 602 passes through the installation part 701 and is suspended on the washing machine housing of the washing machine. The shock absorption and buffering device 3 is sleeved on the suspension rod 602, located between the installation part 701 and the shock absorption sleeve 2, and covers the upper end surface of the shock absorption sleeve 2 to reduce vibration.

[0069] The washing machine suspension shock absorber is installed at the four corners of the washing machine. An installation part 701 is provided at the bottom of the water collection structure of the washing machine. The lower end of the suspension rod 602 assembly is installed in the installation part 701 at the bottom of the water collection structure of the washing machine, and the other end is hung on the corresponding corner of the washing machine housing.

[0070] A shock absorption unit is provided inside the shock absorption sleeve 2. The shock absorption unit includes a spring group 5 and a spring seat for fixing the spring group 5. The suspension rod 602 plays a connecting role. The installation part 701 is generally a suspension seat with a suspension hole. The suspension rod 602 passes through the suspension hole and is hung on the washing machine housing at the corresponding position. The shock absorption sleeve 2 at the lower end of the suspension rod 602 is stuck below the suspension hole. In this way, when the washing machine vibrates, the suspension rod 602 assembly can play a role in reducing the vibration of the inner barrel and the washing machine.

[0071] The shock absorption and buffering device 3 provided on the suspension shock absorber of this embodiment is located between the installation part and the shock absorption sleeve 2 and covers the upper end surface of the shock absorption sleeve 2. Compared with the existing shock absorption pads, the contact area with the shock absorption sleeve 2 and the installation part is increased. Therefore, when the washing machine vibrates and the suspension shock absorber moves up, down, left, and right, the area covered by the flexible material between the installation part of the water collection structure and the shock absorption sleeve 2 increases, and the pressure and vibration generated by the collision and vibration between the two are reduced, resulting in a good shock absorption effect and can assist in reducing the vibration of the washing machine.

[0072] In addition, the contact areas of the shock absorption and buffering device 3 with the shock absorption sleeve 2 and the mounting part are both increased, which can not only better reduce the vibrations of the suspension shock absorber and the washing machine, but also reduce the pressure and impact on the shock absorption and buffering device 3 itself. The force received is dispersed, making it not easily damaged, prolonging its service life, and saving the replacement cost.

[0073] In a further solution, the shock absorption sleeve 2 includes a bracket 21 and a sleeve 22 formed integrally. The bracket 21 seals the upper opening of the sleeve 22. The bracket 21 includes a tubular flange 21-1 extending axially upward along the suspension rod 602 and a transition structure 21-2 extending from the tubular flange 21-1 to the upper opening of the sleeve 22. The shock absorption and buffering device 3 is provided with a sleeving part 31 and a shock absorption part 32. The sleeving part 31 is sleeved on the tubular flange 21-1, and the shock absorption part 32 covers the outer surface of the transition structure 21-2.

[0074] The bracket 21 and the sleeve 22 of the shock absorption sleeve 2 are integrally formed to seal the upper port of the sleeve 22. The lower port of the sleeve 22 is sealed by a sealing cover 6, and a closed chamber is formed inside the shock absorption sleeve 2. The spring group 5 is wrapped in the shock absorption sleeve 2 to avoid being corroded and damaged. The bracket 21 has a tubular flange 21-1 extending axially upward along the suspension rod 602, and a fixing seat for fixing the spring seat is formed by extending downward along the axial direction of the suspension rod 602. Since the diameter of the tubular flange 21-1 is smaller than the diameter of the sleeve, the lower end of the tubular flange 21-1 needs to extend outward and downward gradually until it is integrated with the upper opening of the sleeve 22, thus forming the transition structure 21-2.

[0075] The shock absorption and buffering device 3 of this embodiment is made of a flexible material. The sleeving part 31 is sleeved on the tubular flange 21-1, and the outside is stuck under the mounting part on the water collecting structure. Therefore, it can play the role of sliding damping, increasing the friction force of the up and down movement of the suspension rod 602 assembly and reducing vibrations. The shock absorption sleeve 2 and the mounting part are generally made of plastic material. When the shock absorption sleeve 2 vibrates up and down, it is easy to collide with the mounting part. The shock absorption part 32 covers the outer surface of the transition structure 21-2, which is equivalent to the entire upper end of the shock absorption sleeve 2 being covered by a flexible material, with a large area. There is a shock absorption and buffering device 3 between the shock absorption sleeve 2 and the mounting part for buffering, reducing the collision and vibration between the shock absorption sleeve 2 and the mounting part, and further reducing the vibration of the washing machine.

[0076] Preferably, the length of the sleeving part 31 is the same as the length of the tubular flange 21-1, completely wrapping the tubular flange 21-1, which can increase the contact area and enhance the sliding damping.

[0077] In a further solution, the sleeving part 31 is sleeved outside the tubular flange 21-1 and keeps in contact with the outer wall of the tubular flange 21-1 to generate sliding damping. The sleeving part 31 is not fixed to the outer peripheral wall of the tubular flange 21-1. It can be in close contact or have a certain gap but still keep in contact. When relative movement occurs, sliding damping can be generated to reduce vibration.

[0078] In a further solution, a protrusion is provided inside the sleeving part 31 and contacts the outer wall of the tubular flange 21-1 to increase the sliding damping. The sleeving part 31 is tubular. Protrusions protruding towards the suspension rod 602 can be provided on the inner wall. Multiple dot-like protrusions can be provided, or strip-like, spiral-like protrusions or the like that can increase the friction force can be provided. They can be arranged regularly or irregularly.

[0079] Preferably, the protrusions are annular ribs arranged at intervals along the circumferential direction of the suspension rod 602. The annular ribs can further increase the sliding damping and reduce vibration.

[0080] In a further solution, the diameter of the tubular flange 21-1 is smaller than the diameter of the sleeve 22. The lower edge of the tubular flange 21-1 extends outward to the upper end opening of the sleeve 22 to form a transition structure 21-2. The outer surface of the transition structure 21-2 is a plane or a curved surface inclined outward from the axial center of the suspension rod 602. The shock-absorbing part 32 is matched with the outer surface of the transition structure 21-2, covers the outside of the transition structure 21-2 and is in contact with it.

[0081] Since the diameter of the tubular flange 21-1 is smaller than the diameter of the sleeve, the lower end of the tubular flange 21-1 needs to extend outward and downward gradually until it becomes integral with the upper end opening of the sleeve 22. The outer surface of the transition structure 21-2 is inclined from the inside to the outside. It can be stuck in the installation part at the upper end of the shock-absorbing sleeve 2. When vibrations occur in the up, down, left and right directions, the extrusion force can be reduced to avoid damage. The shock-absorbing part 32 covers the outside of the inclined transition structure 21-2, and can further reduce the vibration of the impact.

[0082] In a further solution, the lower edge of the sleeving part 31 extends outward to form a shock-absorbing part 32. The inner surface of the shock-absorbing part 32 is matched with the outer surface of the transition structure 21-2. The shock-absorbing part 32 covers the transition structure 21-2 and is in smooth transition with the outer surface of the sleeve 22. Preferably, the inner surface of the shock-absorbing part 32 and the outer surface of the transition structure 21-2 are arc surfaces that match each other.

[0083] The size and shape of the shock-absorbing portion 32 are matched with the transition structure 21-2 of the bracket 21. The transition structure 21-2 is a plane or a curved surface that slopes outward from the axial center of the suspension rod 602. Correspondingly, the shock-absorbing portion 32 is also a plane or a curved surface that slopes outward from the lower edge of the sleeving portion 31, and can wrap and cover the outer surface of the transition structure 21-2 and contact it. In this way, the covering area of the flexible material is greatly increased, and they cooperate with each other and are not easily displaced. When the shock-absorbing sleeve 2 collides with the installation portion, the force can be reduced and the vibration can be reduced. The shock-absorbing portion 32 is smoothly transitioned with the outer surface of the sleeve 22. First, it is beneficial to aesthetics. Second, the edge of the shock-absorbing portion 32 will not be squeezed, or there will be no situation where the upper edge of the shock-absorbing sleeve 2 is not covered by the shock-absorbing portion 32, which is beneficial to reducing vibration. The inner surface of the shock-absorbing portion 32 and the outer surface of the transition structure 21-2 are arc surfaces that match each other, which can further reduce the force during impact and avoid being damaged by extrusion.

[0084] In a further solution, a circumferential annular concave platform 4 is provided at one end of the transition structure 21-2 close to the sleeve 22. The edge of the shock-absorbing portion 32 is matched with the annular concave platform 4. When the shock-absorbing and buffering device 3 is sleeved and installed on the suspension rod 602, the edge of the shock-absorbing portion 32 is stuck in the annular concave platform 4.

[0085] A circumferential annular concave platform 4 is provided at the lower end of the transition structure 21-2, and the edge of the shock-absorbing portion 32 is cooperatively arranged and inserted into the annular concave platform 4, which can better prevent the shock-absorbing and buffering device 3 from shifting in position, ensuring that the upper end of the shock-absorbing sleeve 2 can still be completely covered during the vibration process, reducing the impact between the shock-absorbing sleeve 2 and the installation portion, and further reducing the vibration.

[0086] In a further solution, the edge of the shock-absorbing portion 32 extends along the axial direction of the suspension rod 602, its thickness is matched with the annular concave platform 4, and it is smoothly transitioned to the outer surface of the sleeve 22.

[0087] The outer surface of the shock-absorbing portion 32 extends from the center to the outside, changes direction at the edge, and extends along the axial direction of the suspension rod 602, and can be buckled on the upper end of the shock-absorbing sleeve 2 to prevent the shock-absorbing and buffering device 3 from shifting in position during the vibration process. At the same time, the edge of the vibrating portion is smoothly transitioned to the outer surface of the sleeve 22, which can protect the outer edge and avoid damage to the corners by the impact during vibration.

[0088] The shock-absorbing sleeve 2 is located at the lower part of the mounting plate 500, so that the shock-absorbing unit 601 does not occupy the space between the washing machine housing 100 and the laundry tub 206 in the horizontal direction, further reducing the obstruction caused by the shock-absorbing unit 601 to the expansion of the laundry tub 206. Moreover, the height of the end of the suspended shock-absorbing member 600 connected to the water collection structure in the longitudinal direction is reduced as much as possible, so that the inclination angle θ between the installed suspended shock-absorbing member and the side wall of the washing machine housing is reduced, and then the occupied space of the suspended shock-absorbing member 600 is reduced, and the available space of the inner tub 200 is increased. When this structure is suspended between the inner tub 200 and the washing machine housing 100, it is possible to increase the diameter of the inner tub 200 without increasing the volume of the washing machine housing 100, achieving the purpose of expansion.

[0089] Further, the edge of the mounting plate protrudes outward to form a mounting portion 701. The lower part of the suspended shock-absorbing member is connected to the mounting portion, and the upper part is connected to the washing machine housing.

[0090] Among them, the mounting portion can also be formed by turning up the edge of the upper opening of the water collection chamber to form the mounting portion 701. In this way, the suspension is more stable;

[0091] Or, the outer wall of the water collection chamber protrudes outward to form a mounting portion.

[0092] Further, the suspended shock-absorbing member can be a suspended suspension rod.

[0093] Embodiment III

[0094] On the basis of Embodiment I and Embodiment II, as Figure 3 shown, in this embodiment, the shock-absorbing structure includes a support shock-absorbing member 800. One end of the support shock-absorbing member 800 is connected to the lower part of the washing machine housing 100, and the other end is connected to the water collection structure, supporting the water collection structure and the inner tub 200 inside the washing machine housing.

[0095] The support shock-absorbing member 800 provides a support force for the water collection structure, supporting the inner tub assembly inside the washing machine housing. When the inner tub assembly vibrates, the vibration of the inner tub assembly is reduced. When it is used in cooperation with the suspended shock-absorbing member, the shock-absorbing effect is greatly improved by the combined action of one up and one down.

[0096] Further, the support shock-absorbing member is inclined, and the end of the support shock-absorbing member connected to the water collection structure is located on the bottom wall of the water collection structure.

[0097] Further, one end of the support shock-absorbing member 800 is movably connected to the water collection structure, and the other end is movably connected to the bottom of the washing machine housing 100. The connection parts of the support shock-absorbing member with the washing machine housing 100 and the water collection structure may twist during vibration. By the way of movable connection, the damage of the connection parts is reduced.

[0098] Furthermore, in order to achieve a better supporting effect, the supporting and damping member 800 is inclined. The supporting and damping member 800 deflects inward from the side wall of the washing machine housing 100 from bottom to top at a certain angle, and the supporting effect of the base is better.

[0099] When both the supporting and damping member 800 and the suspension damping member 600 are provided in the washing machine, during vibration of the water collecting structure and the inner tub 200, a better damping effect is achieved through the combined action of the two.

[0100] Preferably, one end of the supporting and damping member 800 connected to the water collecting structure is located on the bottom wall of the water collecting structure, that is, the lower part of the mounting plate. This setting method is particularly suitable for a structure with both a suspension damping member 600 and a supporting and damping member 800. This setting method disperses the installation positions and reduces damage to the water collecting structure. The supporting and damping member is arranged at the lower part of the mounting plate and is circumferentially evenly distributed around the driving device, so that the stress points are dispersed.

[0101] The described supporting and damping member 800 is preferably a damping spring or a damper. Further, as Figures 3-4 shown, the damping structure further includes a horizontal damping member 11. The horizontal damping member 11 is horizontally arranged between the water collecting structure and the washing machine housing 100 and is respectively connected to the water collecting structure and the washing machine housing 100 to reduce the vibration of the inner tub and the water collecting structure in the horizontal direction.

[0102] During the laundry process, when the rotation speed of the inner tub 200 decreases to a certain range (generally near the resonance point), the inner tub 200 shakes severely in the horizontal direction, and it is very easy to cause the inner tub to collide with the washing machine housing, resulting in damage to the inner tub 200 and / or the washing machine housing 100. However, both the supporting and damping member and the suspension damping member are inclined. Limited by the setting angle, they mainly balance the vibration in the vertical direction, and the damping effect in the horizontal direction is relatively poor. In order to reduce the shaking of the inner tub 200 in the horizontal direction, the present invention provides a horizontal damping member 11 to reduce the vibration during the laundry process, enhance the anti-deviation ability of the inner tub 200 and the driving device 300, especially reduce the vibration when the rotation speed of the washing machine reaches the resonance point, and reduce the possibility of the inner tub 200 and / or the driving device 300 hitting the washing machine housing 100. By providing a horizontal damping member, the damping ability in the horizontal direction is improved.

[0103] Furthermore, the horizontal damping member is arranged between the outer wall of the water collecting cavity and the inner wall of the washing machine housing and is respectively connected to the outer wall of the water collecting cavity and the inner wall of the washing machine housing.

[0104] Further, the horizontal shock absorber 11 includes a shock absorption mechanism (not shown in the figure), a first shock absorption connector 12 and a second shock absorption connector 13 connected to the shock absorption mechanism. The first shock absorption connector 12 and the second shock absorption connector 13 are respectively connected to the installation assembly and the inner wall of the washing machine housing 100.

[0105] By connecting the first shock absorption connector 12 and the second shock absorption connector 13 to the inner wall of the water collection structure and the washing machine housing 100 respectively, the horizontal shock absorber 11 is horizontally installed between the two, enhancing the anti-deviation ability of the inner tub 200 and the drive device 300 and reducing the possibility of hitting the washing machine housing.

[0106] Further, the shock absorption mechanism, the first shock absorption connector 12 and the second shock absorption connector 13 are all arranged in the horizontal direction. The first shock absorption connector 12 and the second shock absorption connector 13 are respectively connected to the outer wall of the water collection cavity 400 and the inner wall of the washing machine housing 100.

[0107] The shock absorption mechanism, the first shock absorption connector 12 and the second shock absorption connector 13 are coaxial, and the axis is arranged in the horizontal direction. The first shock absorption connector 12 and the second shock absorption connector 13 move relative to each other, triggering the shock absorption mechanism to act, achieving a better horizontal shock absorption effect.

[0108] Further, the horizontal shock absorber 11 is movably connected to the water collection structure and / or the washing machine housing 100. During the washing process, the inner tub 200 and the water collection structure will generate compound vibrations in the longitudinal and horizontal directions, generating torsional forces. Therefore, by movably connecting the horizontal shock absorber 11 to the water collection structure and / or the washing machine housing 100, the torsional force of the horizontal shock absorber 11 on the water collection structure and the washing machine housing 100 is overcome, reducing damage to the inner tub 200, the water collection structure and the washing machine housing 100. Further, the first shock absorption connector 12 and the second shock absorption connector 13 are respectively rotatably connected to the outer wall of the water collection cavity 400 and the inner wall of the washing machine housing 100. Through the rotational connection method, the connection part absorbs the torsional force and reduces damage to each component.

[0109] Furthermore, the first shock absorption connector 12 is hinged to the outer wall of the water retaining rib 501, and the second shock absorption connector 13 is hinged to the inner wall of the washing machine housing 100.

[0110] Since the water collection cavity 400 is a cavity structure, by connecting the first shock absorption connector 12 and the second shock absorption connector 13 to the inner wall of the water retaining rib 501 and the washing machine housing 100 respectively, on the one hand, the horizontal shock absorber 11 reduces the possibility of the inner tub 200 and the water collection structure hitting the washing machine housing 100 during the washing process, enhancing the anti-deviation ability of the inner tub 200 and the water collection structure. On the other hand, the water retaining rib has high strength, and the first shock absorption connector 12 is hinged to the outer wall of the water retaining rib 501, which is not easily damaged.

[0111] Specifically, a first mounting seat 14 is provided on the outer wall of the water retaining rib 501, and a second mounting seat 15 is provided on the inner wall of the washing machine housing 100. The first mounting seat 14 and the second mounting seat 15 are at the same height in the vertical direction. The horizontal shock absorber includes a shock absorption mechanism, a first shock absorption connecting member 12 and a second shock absorption connecting member 13. The shock absorption mechanism, the first shock absorption connecting member 12 and the second shock absorption connecting member 13 are coaxial and this axis passes through the first mounting seat 14 and the second mounting seat 15. The first shock absorption connecting member 12 is hinged to the first mounting seat 14, and the second shock absorption connecting member 13 is hinged to the second mounting seat 15. The suspension shock absorber 600, the support shock absorber 800 and the horizontal shock absorber 11 are all connected to the water collecting structure, and each type of shock absorber is evenly distributed around the water collecting structure, making the force received by the water collecting structure more balanced. When the shock absorption structure includes at least two of the suspension shock absorber 600, the support shock absorber 800 and the horizontal shock absorber 11, while satisfying the uniform distribution of each type of shock absorber, different types of shock absorbers are staggered, so that the shock absorbers with the same acting force on the water collecting structure are evenly dispersed, achieving a better shock absorption effect.

[0112] Embodiment 4

[0113] As Figures 1-6 shown, on the basis of Embodiments 1-3, the washing machine of this embodiment further includes a drainage structure for draining the water in the water collecting structure out of the washing machine. The water inlet end of the drainage structure is communicated with the water collecting structure, and the water outlet end extends outside the washing machine.

[0114] By providing the drainage structure, the water in the water collecting structure can be drained while water is being inlet, which can further reduce the height of the water inlet structure, provide a larger space when the inner tub shakes / vibrates, and further reduce the possibility of barrel collision.

[0115] Solution 1: The entire drainage structure is located below the water collecting structure, and the drainage structure is in a normally open state, that is, the highest point of the drainage structure is lower than the water collecting structure. The drainage structure is in a normally open state, and the water in the water collecting structure automatically drains through the drainage structure under the action of gravity.

[0116] Further, the drainage structure includes a drainage channel 401. The water inlet end of the drainage channel 401 communicates with the water collection cavity 400 of the water collection structure. The entire drainage channel 401 is located below the water inlet end of the drainage channel 401, and the drainage channel 401 is in a normally open state. Since the drainage channel 401 is in a normally open state and the entire drainage channel is located below the water inlet end of the drainage channel, when the water in the inner tub enters the water collection structure, due to the normally open state of the drainage channel, the water directly drains out from the drainage channel 401. Further, the drainage channel 401 is directly connected to the bottom wall of the water collection cavity 400 and remains in a normally open state, enabling all the water in the water collection cavity 400 to be drained without residue, which will not affect the performance of the water collection cavity 400. At the same time, the normally open state allows the water to be drained at all times.

[0117] Further, the height of the drainage channel 401 gradually decreases from the water inlet end to the water outlet end, reducing the parts where the water flow changes direction and gradually decreasing the potential energy, making the water drainage smoother.

[0118] Solution two: The drainage structure includes a drainage channel 401 and a control mechanism 802 for controlling the on / off of the drainage structure. The control mechanism 802 is arranged on the drainage channel 401 and communicates with the drainage channel 401. The washing machine includes a main control device 900. The control mechanism 802 is electrically connected to the main control device 900 to control the opening / closing of the control mechanism 802, so as to make the drainage channel 401 conduct / block.

[0119] When the washing machine drains / dehydrates, the control mechanism 802 is in an open state and the drainage channel 401 is in a conducting state. The water in the water collection structure can be drained from the drainage channel 401 at all times under the action of gravity.

[0120] When the washing machine fails or is not suitable for drainage or the laundry is finished, the main control device 900 controls the control mechanism to close, blocking the drainage channel and preventing the water from flowing out.

[0121] Among them, the control mechanism 802 is a normally open solenoid valve. The normally open solenoid valve communicates with the drainage channel 401 and is electrically connected to the main control device 900. The main control device 900 controls the opening / closing of the normally open solenoid valve to control the conduction / blockage of the drainage channel 401.

[0122] Further, the drainage structure further includes a detection device 801 for detecting the water level height in the water collection structure. The detection device 801 is electrically connected to the main control device 900. The detection device 801 detects the water level in the water collection structure and transmits it to the main control device 900. The main control device 900 controls the opening / closing of the control mechanism 802 according to the result detected by the detection device 801.

[0123] The detection device 801 detects the water level in the water collection structure and transmits it to the main control device 900. When the water level in the water collection structure is higher than a preset value, the control mechanism 802 is controlled to open, and the water in the water collection structure is discharged.

[0124] When the water level in the water collection structure is higher than a preset value, the control mechanism 802 is controlled to open, and the water in the water collection structure is discharged. When the water level in the water collection structure is lower than a preset value, the control mechanism 802 is controlled, such as changing the position of the washing machine.

[0125] The detection device 801 is a water level sensor or a pressure sensor arranged in the water collection structure, and the control mechanism 802 is a solenoid valve.

[0126] Embodiment Five

[0127] As Figures 5-6 As shown, on the basis of Embodiment One - Embodiment Four, the washing machine of this embodiment further includes a detected end and a detection end for detecting the position of the detected end. The detected end and the detection end are respectively arranged on the inner tub 200 and the washing machine housing 100. The detection end is electrically connected to the main control device. The detection end detects the distance between the detected end and the detection end, and the control device controls the washing machine according to the detection result of the detection end.

[0128] During dehydration, the inner tub rotates to discharge the water in the inner tub through the dehydration port 201. When the rotation speed of the inner tub is near the resonance point, it is easy to cause a collision between the inner tub 200 and the washing machine housing 100. If a collision occurs, since the inner tub is in a high-speed rotation state, the generated impact force is very large, and it is easy to cause damage or even damage to the inner tub and / or the washing machine housing.

[0129] By respectively arranging a mutually cooperating detection end and a detected end on the washing machine housing and the inner tub, the detection end detects the position of the detected end. When the inner tub approaches the washing machine housing and exceeds the safe distance, the detection end detects that the detected end is too close to it, and transmits the detection signal to the main control device. This safe distance means that if the distance between the inner tub and the washing machine housing is less than or equal to this safe distance, there will be a barrel collision, and measures need to be taken to prevent the barrel collision. If the distance between the inner tub and the washing machine housing is greater than this safe distance, there will be no barrel collision and the washing machine operates normally.

[0130] Solution One: The detection end can continuously detect the position of the detected end and transmit the detection signal to the main control device 900. The main control device 900 judges whether the distance between the detected end and the detection end is less than a preset value (safe distance). If it is less than or equal to this preset value, it means that the inner tub 200 may collide with the barrel, and the main control device 900 controls the washing machine to perform corresponding operations.

[0131] For example, the detection end is an infrared receiving end, and the detected end is an infrared transmitting end. Distance measurement is performed through infrared rays, and the detection signal is transmitted to the main control device 900. The main control device 900 calculates the distance A between the inner tub 200 and the washing machine housing 100. When A is less than or equal to the preset value, it indicates that the inner tub 200 and the washing machine housing 100 may collide, and then the washing machine is controlled to pause or stop or decelerate or the alarm device is controlled to give an alarm.

[0132] Solution 2: When the detected end is too close to the detection end, the detection end detects the detected end and transmits the signal to the main control device 900. When the distance between the detection end and the detected end is large, the detection end cannot detect the detected end. When the distance between the detection end and the detected end is less than the safe distance, the detection end can only detect the detected end. At this time, the inner tub 200 and the washing machine housing 100 may collide. The detection end transmits the signal that it has detected the detected end to the main control device 900, and the main control device 900 controls the washing machine to perform corresponding operations.

[0133] Based on Solution 2, the detected end is a magnetic member 901 that can generate a magnetic field, and the detection end is a magnetic sensitive element 903. When the magnetic member 901 approaches the magnetic sensitive element 903 and triggers the magnetic sensitive element 903 to act, the magnetic sensitive element 903 transmits the detection signal to the main control device 900.

[0134] The magnetic sensitive element 903 is an element that can be triggered under a certain magnetic force and can be a magnetic sensitive switch.

[0135] Since the magnetic member 901 and the magnetic sensitive element 903 are respectively arranged on the inner tub 200 and the washing machine housing 100, when the inner tub 200 is far from the washing machine housing 100, the magnetic member 901 and the magnetic sensitive element 903 are also far apart. The magnetic sensitive element 903 is not affected by the magnetic force or is affected by a small magnetic force and cannot trigger the magnetic sensitive element 903 to act. When the distance between the inner tub 200 and the washing machine housing 100 is less than the safe distance, the magnetic sensitive element 903 acts under the magnetic force of the magnetic member 901, triggering the magnetic sensitive element 903 to transmit the signal to the main control device 900, and the main control device 900 controls the washing machine to act.

[0136] Among them, the magnetic member 901 is a magnet 902. The magnet 902 can be a permanent magnet 902 or an electromagnet 902. The magnetic sensitive element 903 is a magnetic sensitive switch, and the magnetic sensitive switch can be a reed switch 904. When using the electromagnet 902, the power source of the electromagnet 902 can be a dry battery, such as an electromagnet 902 with a battery, or the power supply device of the washing machine.

[0137] Since the magnet 902 and the reed switch 904 are respectively arranged on the inner drum 200 and the washing machine housing 100, when the inner drum 200 is far away from the washing machine housing 100, the magnet 902 and the reed switch 904 are also far apart, and the reed switch 904 is not affected by the magnetic force or the magnetic force it receives is small, and the two reed leaves of the reed switch 904 cannot be triggered to be magnetized and attracted under the action of the magnetic force. When the distance between the inner drum 200 and the washing machine housing 100 is less than the safe distance, the reed switch 904 is attracted under the magnetic force of the magnet 902, triggering the circuit between the reed switch 904 and the main control device 900 to be energized, and the main control device 900 receives the signal to control the operation of the washing machine.

[0138] Furthermore, a fixing part 905 is provided on the outer wall of the inner barrel 200 or the inner wall of the washing machine housing 100, and the fixing part 905 is fixedly connected to the inner barrel 200 or the washing machine housing 100 to form a closed chamber, and the magnetic part 901 is located in the closed chamber, so as to fix the magnetic part 901 on the inner barrel 200 or the washing machine housing 100.

[0139] Furthermore, the magnetic member 901 is in surface contact with the wall of the closed chamber.

[0140] The above structure is particularly suitable for setting the magnetic part 901 on the inner barrel 200. Since the inner barrel 200 is basically in a rotating state during the washing process, if it is simply plugged in or connected with screws, the plug-in part or the screw-in part of the inner barrel 200 may easily loosen or fall off when it rotates or vibrates, causing serious problems such as jamming. By setting the magnetic part 901 in a closed chamber, the magnetic part 901 is in surface contact with the closed chamber, the force is evenly distributed, it is not easy to be damaged, and it is safer.

[0141] Furthermore, the fixing member 905 is a fixing plate, the middle portion of which is recessed in a direction away from the inner barrel 200 to form a concave cavity 906, the magnetic member 901 is located in the concave cavity 906, and the fixing member 905 is fixedly connected to the inner barrel 200 to close the opening position of the concave cavity 906 to form a closed chamber, and the magnetic member 901 is covered in the concave cavity 906.

[0142] By setting the cavity 906 on the fixing part 905, on the one hand, the manufacturing process is simple and the cost is lower. On the other hand, it can be directly installed on the existing inner barrel 200 without modifying the structure of the inner barrel 200, which is simple and convenient to operate. On the other hand, there is no need to groove the inner barrel 200, which will not reduce the strength of the inner barrel 200.

[0143] Among them, the concave cavity 906 can also be formed by a partial inward depression of the outer wall of the inner tub 200. The fixing member 905 is a plate-shaped member covering the concave cavity and fixedly connected to the inner tub. Although this structure requires improvement of the inner tub 200, it does not occupy the space between the inner tub 200 and the washing machine housing 100, does not affect the increase in the diameter of the inner tub 200, and does not affect the capacity expansion of the washing machine. Of course, it is also possible to provide the concave cavity 906 on both the fixing member 905 and the outer wall of the inner tub 200, and the two parts of the concave cavity 906 are closed to form a closed chamber.

[0144] Further, the closed chamber formed by the sealed connection between the fixing member 905 and the inner tub 200 is a sealed chamber, and the magnetic member 901 is sealed in the sealed chamber.

[0145] During the laundry process, the inner tub 200 will inevitably get wet, and water may seep into the closed chamber. If it is a permanent magnet 902, the interference is relatively small. However, if the magnetic member 901 is an electromagnet 902 and the closed chamber is not a sealed chamber, it may cause damage to the electromagnet 902 and result in the loss of magnetism. Therefore, a sealed chamber is required.

[0146] Further, a sealing gasket is provided at the connection part between the fixing member 905 and the inner tub 200 to achieve better sealing. The fixing member 905 is detachably connected to the inner tub 200, which can be a screw connection or a snap connection.

[0147] Further, a mounting seat 907 for mounting the magnetic sensor element 903 is provided on the inner wall of the washing machine housing 100 or the outer wall of the inner tub 200. The mounting seat 907 is electrically connected to the main control device 900, and the magnetic sensor element 903 is assembled on the mounting seat 907 to energize the magnetic sensor element 903 and the main control device 900.

[0148] Since the magnetic sensor element 903 is easily damaged and loses its function during a collision, by providing the mounting seat 907 and mounting the magnetic sensor element 903 on the mounting seat 907, on the one hand, it plays a fixing role, enabling it to form a good electrical connection relationship with the main control device 900, reducing the phenomena of exposure and water contact short circuit, and on the other hand, it plays a protective role for the magnetic sensor element 903 to prevent it from being damaged by collision.

[0149] Further, an anti-collision part is provided on the mounting seat 907 to prevent the inner tub 200 from colliding with the washing machine housing 100 and damaging the magnetic sensor element 903. By providing the anti-collision part on the mounting seat 907, the safety of the magnetic sensor element 903 is improved and its service life is extended.

[0150] Specifically, the mounting seat 907 is arranged on the inner wall of the washing machine housing and protrudes from the inner wall of the washing machine housing 100. The outer edge of the mounting seat 907 is larger than the outer circumference of the magnetic sensor element 903, and the magnetic sensor element 903 is completely wrapped within the mounting seat 907. This structure is the simplest and has the best effect.

[0151] Furthermore, the anti-collision part is a boss 908 formed by the local outward protrusion of the inner wall of the washing machine housing 100. The outer edge of the boss 908 is larger than the outer circumference of the magnetic sensor element 903. When the inner tub 200 collides with the washing machine housing 100, due to the supporting effect of the boss 908, it cannot contact the magnetic sensor element 903, thus achieving the effect of protecting the magnetic sensor element 903.

[0152] The magnetic sensor element 903 can be assembled on the upper part of the boss 908 for convenient installation and replacement, or can be installed on the lower part of the boss 908. Since the inner tub generally contacts the boss first at the upper part, this structure can design the volume of the boss 908 to be relatively small without affecting the expansion of the inner tub 200.

[0153] Among them, the mounting seat 907 can also be a groove arranged on the inner wall of the washing machine housing 100. The side wall of the groove forms an anti-collision part to protect the magnetic sensor element 903. The magnetic sensor element 903 is snapped into the groove, and the opening of the groove is small or inclined upward.

[0154] Furthermore, the detected end and the detection end are relatively arranged at the upper parts of the inner tub 200 and the washing machine housing 100 and both surround the inner tub 200 for one week. Since the barrel collision generated during the rotation of the inner tub 200 may occur in all directions, therefore, in order to achieve a better anti-barrel-collision effect, both the detected end and the detection end are arranged for one week to detect the possibility of barrel collision in all directions.

[0155] Specifically, Scheme 1: The detected end is a permanent magnet 902. The permanent magnet 902 is annular to form a magnetic ring. The magnetic ring is sleeved on the outer wall of the inner tub 200 and surrounds the outer wall of the inner tub 200 for one week. The magnetic sensor element 903 is a reed switch 904 arranged on the inner wall of the washing machine housing 100. A plurality of reed switches 904 are arranged, and the plurality of reed switches 904 are all relatively arranged with the magnetic ring and surround the inner tub 200 for one week. Each reed switch 904 is electrically connected to the main control device 900 respectively, and the reed switches are preferably evenly distributed.

[0156] During the laundry process, if the center of gravity of the inner tub 200 shifts, causing the inner tub 200 to approach the inner wall of the washing machine housing 100, when the distance between the inner tub 200 and the inner wall of the washing machine housing 100 is less than or equal to the safety distance, the magnetic field intensity of the magnet 902 magnetizes the two reeds of the reed switch 904 and causes them to attract and close, enabling the circuit between the reed switch 904 and the main control device 900 to conduct, thus transmitting this signal to the main control device 900. The main control device 900 controls the washing machine to perform corresponding operations, such as stopping the drive device 300 that drives the inner tub 200 to rotate or controlling the alarm device to give an alarm.

[0157] Solution Two:

[0158] The detected end is composed of multiple permanent magnets 902. The multiple permanent magnets 902 are connected end to end to surround the outer wall of the inner tub 200 for one week. There are multiple reed switches 904 provided on the washing machine housing 100. The adjacent reed switches 904 are attached and arranged in a circle. Each reed switch 904 is electrically connected to the main control device 900 respectively to achieve monitoring.

[0159] Alternatively, multiple permanent magnets 902 are arranged at intervals on the outer wall of the inner tub 200 and surround the inner tub 200 for one week. The permanent magnets 902 are evenly distributed. There are multiple reed switches 904 provided on the washing machine housing 100. The multiple reed switches 904 are connected to form a circle. Each reed switch 904 is electrically connected to the main control device 900 respectively to achieve monitoring.

[0160] The permanent magnet 902 is preferably arranged at the upper end of the side wall of the inner tub 200. If a balance ring is provided on the upper part of the inner tub 200, the permanent magnet 902 can be arranged on the balance ring. Since the balance ring is the upper part of the inner tub 200, it is a more vulnerable part to impact.

[0161] Furthermore, the washing machine further includes an actuator. The actuator is electrically connected to the main control device 900. The detected end approaches the detection end, and the detection end transmits the signal to the main control device 900. The main control device 900 controls the actuator to act.

[0162] For example, when the inner tub 200 collides with the washing machine housing 100, the permanent magnet 902 approaches the reed switch 904. The magnetic field generated by the permanent magnet 902 magnetizes and attracts the two reeds of the reed switch, and the circuit connecting the reed switch 904 and the main control device 900 conducts, transmitting the signal that the inner tub 200 is too close to the washing machine housing 100 to the main control device 900. The main control device 900 determines whether the inner tub collides with the washing machine housing or whether there is a possibility of colliding with the washing machine housing based on whether the reed switch conducts. If so, it controls the actuator to act. If not, the washing machine continues to operate normally.

[0163] Specifically, if the reed switch is turned on, the distance between the inner tub and the washing machine housing is less than or equal to the safe distance, indicating that barrel collision has occurred or is likely to occur. The main control device controls the actuator to act and prevent the inner tub 200 from hitting the washing machine housing 100. If not, the distance between the inner tub and the washing machine housing is greater than the safe distance, and the washing machine operates normally.

[0164] For washing machines of different models or types, the safe distance is different. By selecting magnets with different magnetic strengths and reed switches with different magnetization and attraction capabilities, the attraction and separation of the reed can be adjusted to match the corresponding washing machine.

[0165] Among them, the actuator is an alarm or a driving device 300 that drives the inner tub 200 to rotate.

[0166] For example, when the two reeds of the reed switch 904 are attracted, the circuit connecting the reed switch 904 to the main control device 900 is turned on, and the signal that the inner tub 200 is too close to the washing machine housing 100 is transmitted to the main control device 900. The main control device 900 controls the alarm to sound an alarm or controls the motor 301 to stop rotating.

[0167] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the technical solution of the present invention, can make some changes or modifications using the technical content prompted above to form equivalent embodiments with equivalent changes. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the present invention.
