It should be noted that the following examples are for the purpose of explaining the present invention and do not limit the scope of the present invention.

As shown in FIGS. 1 to 12, this embodiment includes an outer tub 1, a drainage device 4 for discharging water inside the outer tub 1 to the outside of the washing machine, and bubbles overflowing from the inside of the outer tub 1. A wall-mounted washing machine is disclosed that includes an overflow pipe 51 for discharging water to the exterior of the washing machine. The drain device 4 communicates with the outer tub 1 to forcibly drain the water in the outer tub 1, and communicates with the drain valve assembly 41 to wash the water discharged from the drain valve assembly 41. It includes a drain pipe 42 that discharges to the outside of the machine, and a mounting structure 43 for fixing and supporting the drain pipe 42 and the overflow pipe 51 to one end of the outer tub 1 near the wall.

In the above scheme, the wall-mounted washing machine differs from the normal drum washing machine in that it is installed on one plane. A wall-mounted washing machine is a washing machine that is hung on a wall. The wall-mounted washing machine of the present invention includes a drainage device 4 . The drainage device 4 includes a drainage valve assembly 41 for forcibly discharging the water in the outer tub 1 from the inside of the outer tub 1 to the outside in a proper cleaning step. is discharged to the outside of the washing machine through the drain pipe 42. In general, the hose that finally discharges water out of the washing machine out of the drain pipe 42 is susceptible to damage due to vibration, collision, and the like. In addition, the wall-mounted washing machine generally includes a ventilation device 5, which realizes air flow between the inside and outside of the outer tub 1, thereby preventing the danger of bursting of the outer tub 1 due to lack of ventilation. Said venting device 5 comprises an overflow pipe 51 . That is, the bubbles and water overflowing from the inside of the outer tub 1 can be discharged to the outside of the washing machine, and the inside of the outer tub 1 can be ventilated. The drain hose of a normal wall-mounted washing machine extends to the outside of the washing machine after penetrating the rear panel. In this case, the fixing action is achieved by penetrating the back plate, but the sharp edges and rib structures that can exist on the edge of the hole on the back plate damage the hose when it vibrates, so the hose damage rate is reduced. get higher Moreover, when the overflow pipe 51 directly communicates with the drain pipe 42, the drain pipe 42 is a hose. The drain device 4 of the wall-mounted washing machine described in the present invention further includes a mounting structure 43 for mounting and fixing the drain pipe 42 and the overflow pipe 51 in order to solve the above problems. The mounting structure 43 fixes and supports the drain pipe 42 and the overflow pipe 51 to one end of the outer tub 1 near the wall, draws water to the rear side of the outer tub 1, and smoothly discharges the water. As a result, when the drain pipe 42 is installed at the front end of the outer tank 1, the appearance of the drain pipe 42 is unsightly due to the exposure of the drain pipe 42, and the connection between the drain hose and the floor drain port cannot be fixed. Damage to the drain hose due to wobbling and vibration is prevented. In addition, by installing the mounting structure 43, the drain pipe 42 and the overflow pipe 51 are prevented from being wobbled or damaged due to vibration during drainage.

Further, a base is provided at one end of the outer tub 1 of the washing machine near the wall, and the drain pipe 42 and the overflow pipe 51 are fixed and supported by the base via a mounting structure 43 .

Furthermore, the tank wall of the outer tank 1 is provided with at least one suspension ear 2 projecting radially outward. The suspension ears 2 are tightly fixedly connected to the wall surface.

More preferably, the drain pipe 42 and the overflow pipe 51 are fixed and supported to one suspension ear 2 near the drain valve assembly 41 below the outer tub 1 via a mounting structure 43 .

In the above plan, the base is installed. The base is a medium that is mounted not only to occupy no space at the wall-side end of the outer tub 1 but also to facilitate fixing and supporting the mounting structure 43 to the wall-side end of the outer tub 1 . In addition, the base is installed because both the cost and the difficulty of operation increase when trying to mount it directly on the wall. As an embodiment, the base may be at least one suspension ear 2 that is installed on the wall of the outer tank 1 and protrudes radially outward, or the base and the suspension ear 2 may be separate means. good. The outer tub 1 of the present invention is suspended from the wall surface via the suspension tabs 2, and does not need to be supported by a member such as a damper. As a result, the number of parts of the washing machine is reduced, thereby further reducing the production cost and the difficulty of assembly of the washing machine. In addition, the overall size and weight of the washing machine is reduced, which optimizes the appearance of the washing machine and improves the reliability of the wall hanging of the washing machine. Also, the drain pipe 42 and the overflow pipe 51 are fixed and supported on the suspension ear 2 via mounting structures 43 . As a result, the drain pipe 42 and the overflow pipe 51 are installed on the rear side of the outer tank 1 and are fixed on the suspension ears 2. Therefore, the drain pipe 42 due to the absence of the back plate in the present invention is not installed. Problems that cannot be fixed are prevented. Therefore, problems such as wobbling, vibration, breakage, and splashing of water caused by the inability to fix the drain pipe 42 can be avoided. Said drain pipe 42 is detachably installed on the suspension ear 2 via a mounting structure 43 so that the operation of mounting, repairing, inspecting, replacing, etc. of the drain pipe 42 is facilitated.

Furthermore, a support member 3 extending in the direction of the outer tub 1 is provided on the wall surface. The support member 3 is inserted through the suspension ear 2 and abuts on the suspension ear 2 to support it. As a specific step of assembling the outer tub 1 in the present invention, the supporting member 3 is attached to the wall surface, and then the suspension tabs 2 are suspended from the supporting member 3 to temporarily fix the outer tub 1 . Finally, the nut is turned up to the support member 3 inserted through the suspension ear 2, and the suspension ear 2 is clamped and fixed on the support member 3 between the wall surface and the nut. As a result, the assembly of the outer tub 1 is achieved. In a preferred embodiment, damping pads are sandwiched and fixed between the wall surface and the suspension ear 2 and between the suspension ear 2 and the nut, respectively, to reduce the noise generated in the washing machine during operation. Further, the suspension lugs 2 may be fixedly connected to the wall surface by bolts, and the suspension lugs 2 may be clamped and fixed to the bolt threads between the nut of the bolt and the wall surface. In a preferred embodiment, a damping pad is clamped and fixed between the wall surface and the suspension ear 2 and between the suspension ear 2 and the nut of the bolt to reduce the noise generated by the washing machine during its operation. Said drain pipe 42 and overflow pipe 51 in the present invention are installed in one suspension ear 2 below the outer tub 1 via a mounting structure 43 . As a result, it is installed behind the outer tub 1 and below the outer tub 1, so that the water is more easily drained without remaining due to the action of gravity. Moreover, the drain pipe 42 and the overflow pipe 51 are fixed while ensuring the appearance. In a preferred embodiment, the drain pipe 42 and the overflow pipe 51 are installed in one suspension ear 2 near the drain valve assembly 41 below the outer tub 1 via a mounting structure 43 . This simplifies the device and also simplifies the installation method and structure of the drain pipe 42 by the mounting structure 43 .

Furthermore, the rear wall of the outer tub 1 is provided with an exhaust hole 53 that communicates with the inside of the outer tub 1 . The overflow pipe 51 is installed at the rear of the outer tub 1 , one end communicating with the inside of the outer tub 1 through an exhaust hole 53 , and the other end communicating with the drainage device 4 .

Preferably, one end of the overflow pipe 51 communicates with the highest water level inside the outer tub 1 through the exhaust hole 53 , and the other end is fixed and supported to one end of the outer tub 1 near the wall via the mounting structure 43 . be.

In the above scheme, the overflow pipe 51 is installed at the rear of the outer tub 1, so that the side space of the outer tub 1 is saved as compared with the case where it is installed at the side of the outer tub 1, and the wall-mounted washing The volume of the machine becomes smaller. In addition, since the overflow pipe 51 can be installed between the rib structures of the rear wall of the outer tub 1 , it does not occupy a large space on the rear wall of the outer tub 1 . The rear wall of the outer tub 1 includes an exhaust hole 53 that communicates with the interior of the outer tub 1 . Since the exhaust hole 53 is provided on the rear wall of the outer tank 1 , the overflow pipe 51 can be easily connected to the rear wall of the outer tank 1 . One end of the overflow pipe 51 communicates with an exhaust hole 53 provided above the rear wall of the outer tank 1, and the other end communicates with the drainage device 4. and water is discharged to the outside of the washing machine through the drain device 4. In a preferred embodiment, the overflow pipe 51 communicates with the highest water level inside the outer tank 1 through the exhaust hole 53, so that unexpected overflow of bubbles and water that occurs when the exhaust hole 53 is installed at a low position , the problem of not being able to wash cleanly due to this is avoided. Also, the other end of the overflow pipe 51 is fixed and supported to one end of the outer tank 1 near the wall via a mounting structure 43 . As a result, the overflow pipe 51 is extended from the bottom of the outer tub 1 toward the drain valve assembly 41 to the front end of the outer tub 1, and then drained through the drain pipe 42, preventing the water from stagnation. be. Alternatively, when the overflow pipe 51 directly communicates with the drain pipe 42, the drain pipe 42 and the overflow pipe 51 vibrate to loosen the connection, thereby preventing overflow.

In the above scheme, the support part 432 supports the drain pipe 42 and the overflow pipe 51 at one end of the outer tub 1 near the wall. That is, one end of the drain pipe 42 and one end of the overflow pipe 51 on the drain side are supported by one end of the outer tub 1 near the wall. By supporting the drain pipe 42 and the overflow pipe 51, and further supporting the drain valve assembly 41 to make the mounting more solid, the drain pipe 42 and the overflow pipe 51 are prevented from wobbling, falling off, or breaking due to the action of vibration. the danger of Normally, the drain valve assembly 41 cannot be installed on the rear side of the outer tank 1 due to elemental limits such as shape and drainage position. Therefore, when the drain pipe 42 is pulled out directly from the drain port of the drain valve assembly 41, the position of the drain pipe 42 is shifted forward, and wobble is likely to occur. In addition, the appearance is poor, and the drain pipe 42 pulled out from the washing machine cannot be fixed. Therefore, by installing the support portion 432 , the drain pipe 42 and the overflow pipe 51 are supported at one end of the outer tank 1 near the wall. By mounting the drain pipe 42 and the overflow pipe 51 on one end of the outer tank 1 near the wall, the mounting portion 431 further realizes the purpose of fixing the drain pipe 42 and the overflow pipe 51, and is capable of prevent danger. In one embodiment, the mounting part 431, the drain pipe 42 and the overflow pipe 51 are integrally molded. In this case, the cost can be saved, and processing and molding can be facilitated, but the degree of difficulty during mounting increases. In another embodiment, the mounting part 431, the drain pipe 42 and the overflow pipe 51 are detachably connected. In this case, attachment and detachment are easy and convenient. In a preferred embodiment, the mounting portion 431 and the support portion 432 are integrally molded.

This guides the water in the drain valve assembly 41 to the drain pipe 42 and supports the drain valve assembly 41 . Further, by supporting the drain pipe 42 and the overflow pipe 51 at one end near the wall of the outer tank 1, the other end of the drain pipe 42 can be easily extended and fixed. In addition, the overflow pipe 51 communicates with the drain pipe 42 through the support part 432 to discharge overflowing water and foam to the outside of the washing machine. In a preferred embodiment, the support 432 is a rigid tube to provide support for the drain tube 42 , overflow tube 51 and drain valve assembly 41 . In the case of soft tubes, on the other hand, no supporting action can be realized. The support part 432 is installed on the same horizontal plane as the drain valve assembly 41 . The structure is simple, does not occupy much space, and is easy to install and repair. In a more preferred embodiment, the support part 432 extends from the drain valve assembly 41 toward one end of the outer tank 1 near the wall while being inclined so as to be gradually lowered. As a result, the water in the support portion 432 flows out from the drain pipe 42 without remaining completely, and the water does not flow back. Also, the bubbles and water discharged from the overflow pipe 51 to the support portion 432 do not flow back. The communication point between the drain pipe 42 and the support portion 432 is lower than the communication point between the support portion 432 and the drain valve assembly 41. This is to prevent backflow.

Therefore, it does not occupy space and does not impair the distribution of the ribs. In a preferred embodiment, the overflow pipe 51 extends downward along the circumferential direction near the axial center of the rear wall of the outer tank 1, so that the length of the overflow pipe 51 is shortened and the bubbles and water are more easily removed. Can be discharged quickly. This avoids the situation in which foam builds up and overflows. In addition, the closer to the axis, the greater the vibration received, so the bubbles are more easily broken and easily flowed out. In a more preferred embodiment, one end of the overflow pipe 51 extends vertically downward from the exhaust hole 53 by a certain distance, and then extends downward along the axial direction near the axis of the rear wall of the outer tank 1 . Stretch. A vertically downwardly extending overflow pipe 51 allows foam and water to flow towards the drainage device 4 more easily.

Moreover, the mounting housing 411 includes a first housing 4111 and a second housing 4112 . The first housing 4111 and the second housing 4112 are detachably connected. The sealing structure 412 is installed at a connection point between the first housing 4111 and the second housing 4112 .

In the above scheme, the mounting housing 411 includes a first housing 4111 and a second housing 4112 that are detachably connected to facilitate mounting and repair of the motor. However, since there is always a gap between the two housings, water/steam can enter the cavity of the mounting housing 411 through the gap and damage the motor. Therefore, by installing the sealing structure 412 at the connecting portion between the first housing 4111 and the second housing 4112, the inadequacy of water/steam entering between the two housings is resolved.

Further, the sealing structure 412 includes a sealing portion 4121 installed at the connecting portion of the first housing 4111/second housing 4112 and an engaging portion 4122 installed at the connecting portion of the second housing 4112/first housing 4111. include. The connecting portion between the first housing 4111 and the second housing 4112 is sealed by the engagement between the sealing portion 4121 and the engaging portion 4122 .

In the above scheme, the sealing structure 412 includes a sealing portion 4121 and an engaging portion 4122 . Engagement of these facilitates installation and repair, and provides a good sealing effect.

Further, the connection point of the first housing 4111/second housing 4112 includes a connection end 5211 surface that engages and contacts each other. The sealing part 4121 is a protrusion projecting from the connection end 5211 of the first housing 4111 /second housing 4112 . The engaging part 4122 is a groove part installed on the connection end 5211 of the second housing 4112 /first housing 4111 .

Further, the protrusion extends into the groove to positionally restrict and seal the connection end 5211 surfaces of the first housing 4111 and the second housing 4112 .

In the above scheme, the sealing part 4121 is a protrusion projecting from the surface of the connection end 5211 , and the engaging part 4122 is a groove installed on the surface of the connection end 5211 . The protrusion extends into the groove to positionally regulate and seal the connection end 5211 surface of the first housing 4111 and the second housing 4112 . Therefore, the sealing effect is excellent, and the risk of water entering the inside of the mounting housing 411 is completely eliminated. When water vapor attempts to enter the interior of the mounting housing 411, it must first bypass the protrusions and grooves. During this process, the water vapor collides with the wall many times and condenses into water, which prevents it from entering the cavity of the mounting housing 411 . In other words, water and steam form an N-type labyrinth seal, which greatly reduces the risk of water and steam entering the cavities of the mounting housing 411, resulting in an excellent sealing effect. In addition, since the projecting portion extends into the recessed groove portion, positional regulation and attachment are achieved, so attachment of the first housing 4111 and the second housing 4112 is greatly facilitated.

Further, the protrusion is a continuous protrusion-like structure installed on the connecting end 5211 surface of the first housing 4111/second housing 4112, and the groove is a continuous groove-like structure that engages with the protrusion. is.

In the above solution, the protrusion has a continuous protrusion-like structure, which seals the entire surface of the connection end 5211, so that the sealing effect is excellent.

Furthermore, the projection has a rectangular cross section in the extending direction, and the groove has the same shape and size as the projection. Preferably, the sides and corners of the rectangle apart from the plane of the connection end 5211 are chamfered.

In the above solution, the protrusion has a rectangular cross-section in the extending direction, and the groove has the same shape and size as the protrusion, so that the sealing effect is excellent. In a preferred embodiment, the sides and corners of the rectangle away from the surface of the connection end 5211 are chamfered so that the recessed groove is not damaged during the mounting or dismounting process.

As shown in FIGS. 1 to 12, the present embodiment includes an outer tank 1 and is further installed at the rear of the outer tank 1 to allow air flow between the inside of the outer tank 1 and the outside of the outer tank 1. A wall-mounted washing machine is disclosed that includes a venting device 5 that provides flow. The aeration device 5 has an exhaust hole formed in the rear wall of the outer tub 1 and communicated with the inside of the outer tub 1 , and one end connected to the exhaust hole and the other end connected to the exhaust vent to remove bubbles and water overflowing from the inside of the outer tub 1 . and an overflow pipe 51 that discharges to the outside of the washing machine, one end communicating with the overflow pipe 51, the other end extending to a position higher than the exhaust hole, and the other end overflowing to the point a vent tube 52 provided with defoaming structures 521 for breaking up foam into a liquid and guiding it to the overflow tube 51;

In the above scheme, the wall-mounted washing machine differs from the normal drum washing machine in that it is installed on one plane. A wall-mounted washing machine is a washing machine that is hung on a wall. Since the wall-mounted washing machine described in the present invention includes the ventilation device 5 that realizes air flow between the inside and outside of the outer tub 1, the risk of bursting of the outer tub 1 due to lack of ventilation is prevented. In addition, since the ventilation device 5 is installed at the rear of the outer tub 1, the side space of the outer tub 1 is saved compared to the case where it is installed at the side of the outer tub 1, and the volume of the wall-mounted washing machine is reduced. become smaller. In addition, since the ventilation device 5 can be installed between the rib structures on the rear wall of the outer tub 1, it does not occupy a large space on the rear wall of the outer tub 1. The aeration device 5 includes an exhaust hole communicating with the interior of the outer bath. Since the exhaust hole is provided on the rear wall of the outer tub 1, the overflow pipe 51 can be easily connected to the rear wall of the outer tub 1. The ventilation device 5 further includes an overflow pipe 51 for discharging foam and water overflowing from the outer tub 1 to the outside of the washing machine. One end of the overflow pipe 51 communicates with an exhaust hole provided above the rear wall of the outer tank 1, and the other end communicates with the drainage device 4. Water is discharged outside the washing machine through the drain device 4 . The ventilation device 5 further includes a ventilation pipe 52 for flowing air between the inside and outside of the outer tub 1 . One end of the vent pipe 52 communicates with the overflow pipe 51 , the inside of the outer tank 1 through the overflow pipe 51 , and the other end communicates with the outside of the outer tank 1 . Thereby, air flow is realized between the inside and the outside of the outer tub 1 . Since the other end of the vent pipe 52 extends to a position higher than the exhaust hole, the bubbles are prevented from directly overflowing from the vent pipe 52 . Since the other end of the vent pipe 52 extends to a position higher than the exhaust hole, a larger pressure is required for the bubbles to overflow from the vent pipe, and the possibility of the bubbles overflowing is greatly reduced. The other end of the vent pipe 52 is further provided with a defoaming structure 521 that destroys the foam that has overflowed up to the point to turn it into a liquid and guides it to the overflow pipe. The defoaming structure 521 prevents bubbles from overflowing from the washing machine through the ventilation pipe 52 and does not interfere with the ventilation function of the ventilation pipe 52 .

Furthermore, the exhaust hole is installed at the highest water level portion inside the outer tank 1 . Preferably, the exhaust hole is located on the diameter of the axis vertically penetrating the rear wall of the outer tub 1 and communicates with the highest water level inside the outer tub 1 .

In the above scheme, the exhaust hole is installed at the highest water level inside the outer tank 1, so if the installation position of the exhaust hole is low, unexpected overflow of bubbles and water may occur, resulting in clean cleaning. Problems such as being unable to do so are avoided. In a preferred embodiment, the vent holes are located on the diameter of the axis that vertically penetrates the rear wall of the outer tub 1, so that it is easier to find and identify the highest water level. Therefore, compared to exhaust holes installed in other positions, it is more difficult to overflow the bubbles, and if the bubbles and water are excessive, it is possible to realize the function to overflow the bubbles and water. is.

Furthermore, the washing machine includes a drainage device 4 . The overflow pipe 51 has one end connected to the exhaust hole and the other end extending downward along the circumferential direction of the rear wall of the outer tank 1 and connected to the drainage device 4 . Preferably, the overflow pipe 51 extends downward along the circumferential direction near the axis of the rear wall of the outer tub 1 . More preferably, one end of the overflow pipe 51 extends vertically downward from the exhaust hole by a certain distance, and then extends downward along the circumferential direction near the axis of the rear wall of the outer tub 1 .

In the above solution, the washing machine further includes a draining device 4 for discharging washing water in the outer tub 1 from the washing machine. One end of the overflow pipe 51 is connected to an exhaust hole to realize air flow between the inside of the outer bath and the outside of the outer bath. Also, the other end is connected to the drain device 4, and the bubbles and water overflowing from the exhaust hole are discharged to the outside of the washing machine through the drain device 4. - 特許庁The other end of the overflow pipe 51 is extended downward along the circumferential direction of the rear wall of the outer tub 1 so that the ribs on the rear wall of the outer tub 1 are not excessively disturbed. is placed between Therefore, it does not occupy space and does not impair the distribution of the ribs. In a preferred embodiment, the overflow pipe 51 extends downward along the circumferential direction near the axial center of the rear wall of the outer tank 1, so that the length of the overflow pipe 51 is shortened and the bubbles and water are more easily removed. Can be discharged quickly. This avoids the situation in which foam builds up and overflows. In addition, the closer to the axis, the greater the vibration received, so the bubbles are more easily broken and easily flowed out. In a more preferred embodiment, one end of the overflow pipe 51 extends vertically downward from the exhaust hole by a certain distance, and then extends downward along the axial direction near the axis of the rear wall of the outer tank. . A vertically downwardly extending overflow pipe 51 allows foam and water to flow towards the drainage device 4 more easily.

Furthermore, one end of the vent pipe 52 communicates with the overflow pipe 51, and the other end extends upward along the rear wall of the outer tank 1 to a position higher than the exhaust hole. Preferably, the vent pipe 52 is close to the overflow pipe 51 and the other end of the vent pipe 52 extends upward along the circumferential direction of the rear wall of the outer tub 1 . More preferably, the other end of the vent pipe 52 extends along the circumferential direction of the rear wall of the outer tub 1 and then vertically extends upward to a position higher than the exhaust hole.

In the above scheme, the ventilation pipe 52 extends upward along the rear wall of the outer tub 1 . As a result, the ventilation pipe 52 is installed on the rear wall of the outer tank 1, but since the vibration of the rear wall of the outer tank 1 is relatively large, the vibration of the ventilation pipe 52 installed on the rear wall of the outer tank 1 also increases. It becomes relatively large, and the bubbles are more likely to break and become liquid due to the action of vibration. In addition, since the ventilation pipe 52 extends upward along the rear wall of the outer tub 1, the space on the side wall of the outer tub 1 is saved as compared with the case where it is installed on the side wall of the outer tub 1. Volume becomes smaller. Also, when installed on the rear wall of the outer tub 1, the vent pipe 52 can be fitted between the ribs of the rear wall of the outer tub 1, thus saving space. In addition, since the other end of the vent pipe 52 extends to a position higher than the exhaust hole, a higher pressure is required for the bubbles to overflow from the vent pipe 52, and the possibility of the bubbles overflowing is greatly increased. to In a preferred embodiment, the vent pipe 52 is close to the overflow pipe 51 and the other end of the vent pipe 52 extends upward along the circumferential direction of the rear wall of the outer tub 1 . As a result, the rib arrangement on the rear wall of the outer tank 1 is not excessively disturbed and the ribs are installed between the ribs, so that the space is not occupied and the distribution of the ribs is not spoiled. Also, the vent pipe 52 is adjacent to the overflow pipe 51 . That is, it is close to the axis of the rear wall of the outer tub 1 . Since the vibration increases as it gets closer to the axis, the bubbles in the ventilation pipe 52 are more likely to break due to the vibration, and are even less likely to overflow from the ventilation pipe 52 . In a more preferred embodiment, the other end of the vent pipe 52 extends along the circumferential direction of the rear wall of the outer tub 1 and then vertically extends upward to a position higher than the exhaust hole. Since it extends in the circumferential direction, the bubbles disappear when the vibration increases. In addition, by continuing to extend upward along the vertical direction, the resistance against rising bubbles is increased, and the tip of the other end of the vent pipe 52 can be easily installed higher than the exhaust hole.

Furthermore, the ventilation pipe 52 is provided with a bent portion 522 . The bent portion 522 is provided at one end of the side communicating with the overflow pipe 51 . Preferably, one end of the vent pipe 52 that communicates with the overflow pipe 51 is provided below the horizontal line of the axis penetrating the rear wall of the outer tank 1 .

In the above scheme, one end of the side communicating with the overflow pipe 51 is provided with a bent portion 522 that has the effect of breaking the overflowing bubbles and preventing the overflow. Interposing the extension of vent tube 52 by bend 522 provides sufficient space for vent tube 52 to extend upwardly. This prevents the vent pipe 52 from exceeding the range of the rear part of the outer tank 1 in the process of extending upward, thereby preventing the space for continued extension from being insufficient. Also, the bent portion 522 breaks the bubble. The bubble is partially destroyed due to the increased pressure at the bend in the conduit. In addition, since the bent portion 522 also increases the pressure against the advancement of the bubbles in the vent pipe 52, the bubbles are more difficult to flow in the vent pipe 52. FIG. In other words, the bent portion 522 serves as an intermediary as well as preventing overflow and breaking bubbles. In addition, since one end of the vent pipe 52 on the side communicating with the overflow pipe 51 is provided below the horizontal line of the axis penetrating the rear wall of the outer tank 1, the difficulty of overflowing the foam into the overflow pipe 51 is reduced. get higher Since the resistance received by the bubbles while continuing downward is smaller than the resistance received by the bubbles while traveling upward from the vent tube 52, the overflow of the bubbles can be effectively reduced.

Further, the bent portion 522 is a protrusion that protrudes outward along the radial direction of the rear wall of the outer tub 1 . Preferably, the projection is arc-shaped. More preferably, at least part of the protrusion is provided below the horizontal line of the axis penetrating the rear wall of the outer tub 1 .

In the above scheme, the bent portion 522 is a protrusion that protrudes outward along the radial direction of the rear wall of the outer tub 1 . The foam overflows upward from the overflow pipe 51 into the vent pipe 52, but the projections projecting radially outward extend the path of the foam and increase the complexity of the path. Increases resistance while continuing to overflow toward Further, the protruding portion that protrudes radially outward includes a first extending portion that extends radially outward and a second extending portion that extends radially inward. The action of vibration that the bubble receives at the first extension changes from greater to lesser, and the action of vibration that it receives at the second extension changes from lesser to greater. In the process of rising from the first extension to the second extension, the bubble gradually collapses under the action of changing vibrations. In addition, in the process of rising from the first extending portion to the second extending portion, the bubbles fluctuate due to the action of vibration, resistance to rising, and changes in the rising path, and the bubbles collide with each other to make it easier to move. to disappear. In a preferred embodiment, the projection is arc-shaped. The arcuate protrusion forms a structure similar to a semicircle and can serve as a bent portion. In addition, this degree of bending facilitates molding. Alternatively, a hose can be easily bent. Therefore, the molding cost does not increase, and mounting is easy. In a more preferred embodiment, at least a portion of the protrusion is provided below the horizontal line of the axis penetrating the rear wall of the outer tub 1, so that the foam overflows into the overflow pipe 51 more difficultly. Since the resistance received by the bubbles while continuing downward is smaller than the resistance received by the bubbles while traveling upward from the vent tube 52, the overflow of the bubbles can be effectively reduced.

Moreover, the defoaming structure 521 is detachably installed at the other end of the vent tube 52 .

In the above scheme, the defoaming structure 521 is detachably installed at the other end of the ventilation pipe 52, so that the defoaming structure 521 can be easily installed, repaired and cleaned. As a result, it is possible to avoid a situation in which foreign matter such as cotton is clogged due to the defoaming structure 521 being installed at the other end of the ventilation pipe 52, thereby hindering ventilation.

Further, the defoaming structure 521 includes a tubular body. The tubular body includes a connecting end 5211 located at one end of the tubular body. Said tubular body is removably installed at the other end of the vent tube 52 via a connecting end 5211 . Preferably, both the outside of the connecting end 5211 and the inside of the other end of the vent tube 52 are provided with screws. The tubular body is connected to the inside of the other end of the vent tube 52 by turning the screw.

A defoaming end 5212 is located at the other end of the tubular body. The inner diameter of the tube of the connecting end 5211 is smaller than the inner diameter of the tube of the defoaming end 5212 .

In the above scheme, the connecting end 5211 is mainly used to detachably install the defoaming structure 521 on the other end of the ventilation tube 52 . The connection end 5211 can be connected to the other end of the vent tube 52 by engagement, screw connection, or the like. In the case of the screw connection method, there are two methods of providing screws inside the connecting end 5211 and the other end of the vent pipe 52, or providing screws outside the connecting end 5211 and inside the other end of the vent pipe 52. There is a screw connection method. In a preferred embodiment, both the outside of the connecting end 5211 and the inside of the other end of the vent pipe 52 are provided with screws, and the tubular body can be pulled inside the other end of the vent pipe 52 by turning the screws. connected to Since the connecting end 5211 is installed inside the other end of the vent pipe 52, the inner diameter of the connecting end 5211 is small, and this also has a certain effect of preventing foam from overflowing. The fact that the inner diameter of the tube of the connecting end 5211 is smaller than the inner diameter of the tube of the defoaming end 5212 corresponds to the emergence of a constricted portion of the connecting end 5211 in the vent pipe 52 . When the bubble reaches the constricted portion of the connecting end 5211, it is pressured by the constriction. This causes some of the bubbles to break under the action of pressure and no more progress to defoamer end 5212 . Also, the remaining portion of the foam continues to defoaming edge 5212 and is intercepted by defoaming edge 5212 and broken.

Further, at least one antifoam plate 5213 is included inside the antifoam end. The defoaming plate 5213 extends into the defoaming end 5212 along radial and axial directions, respectively. Between the defoaming plate 5213 and the inner wall of the tubular body and/or between the defoaming plate 5213 there is a gap for ventilation. Preferably, the defoaming plate 5213 extends from the interface between the connecting end 5211 and the defoaming end 5212 toward the end of the defoaming end 5212 . More preferably, the antifoam plate 5213 is integrally molded inside the antifoam end 5212 .

In the above solution, the antifoaming plate 5213 is included inside the antifoaming end to prevent foam from overflowing. The antifoaming plate 5213 is located in the center of the antifoaming end 5212 in the radial direction and extends along the axial direction. In a preferred embodiment, the antifoaming plate 5213 extends to the boundary between the antifoaming end 5212 and the connecting end 5211 along the axial direction. When the foam overflows from the connecting end 5211 toward the defoaming end 5212, it is first pressed by the constricted portion of the connecting end 5211 and partly broken, and the remaining portion is pressed again by the defoaming plate 5213 after being pressed. destroyed by Therefore, bubbles do not overflow from the defoaming end 5212 . In addition, since the gap between the antifoaming plate 5213 and the inner wall is a gap for ventilation, the antifoaming structure 521 can also prevent bubbles from overflowing on the premise that the ventilation function of the vent pipe 52 is realized. is. The anti-flood part includes at least two antifoam plates 5213 . The defoaming plates 5213 are installed parallel to or cross each other. Between the defoaming plates 5213 and between the defoaming plate 5213 and the inner wall of the defoaming end 5212, there are gaps for ventilation. When the foam overflows from the connecting end 5211 toward the defoaming end 5212, it is first pressed by the constricted portion of the connecting end 5211 and partly broken, and the remaining portion is pressed again by the defoaming plate 5213 after being pressed. destroyed by Therefore, bubbles do not overflow from the defoaming end 5212 . The integrally molded antifoam plate 5213 eliminates machining and mounting procedures, saves cost, and is easy to use.
