Description

Technical Field

[0001] This utility model relates to the field of clothing washing equipment technology, and in particular to the exhaust structure of a small washing and drying machine. Background Technology

[0002] With the continuous development of laundry equipment technology and the increasing demands of users for quality of life, washing machines of various functions and sizes have emerged on the market to meet diverse needs, such as washer-dryer combos and hosiery washing machines. To reduce the spread of bacteria between inner and outer garments, and between adult and baby clothing during the washing process, washing machine manufacturers have specifically produced small washing machines for washing underwear and baby clothes to meet user needs.

[0003] To meet users' needs for quick clothes drying, a drying device is installed inside the washing machine. For example, Chinese invention patent CN112481961A discloses a washer-dryer combo machine, in which a drying module (2) is installed on the top of the washing machine, and the air outlet of the drying module (2) is wholly or partially submerged in the housing (1). A flexible sealing ring (3) is provided between the housing (1) and the washing tub (4) to prevent hot air from escaping. The washer-dryer combo machine of this patent is equipped with a drying module, which realizes the function of drying clothes after washing. However, the hot airflow generated by the drying module of the washer-dryer combo machine of this patent enters the washing tub to dry the clothes. At the same time, the gap between the housing and the washing tub is sealed by the flexible sealing ring, and the interior of the washing tub is basically a closed space. The moisture on the clothes turns into water vapor after drying. The water vapor cannot be discharged in the closed space, resulting in poor drying effect. Utility Model Content

[0004] In view of this, the present invention aims to provide an exhaust structure for a small washer-dryer combo. It employs an airflow channel on the washing tub, connecting the tub to the outside. Hot airflow is discharged from the tub through the airflow channel to the outside of the washing machine. The tub and the shell assembly are flexibly connected to eliminate vibrations during washing. The airflow channel is connected to the shell assembly via a corrugated pipe, preventing damage to the airflow channel from tub shaking. The ends of the corrugated pipe are fixed to the liner vent with seals. The vent on the shell body is sealed by a vent end cap with ventilation holes connected to ventilation pipes that extend into the corrugated pipe. This solves problems such as poor drying effect and hot airflow flowing between the tub and the shell assembly, leading to temperature increases.

[0005] To solve the above problems, this utility model provides an exhaust structure for a small washer-dryer combo. The combo includes a washing tub and a shell assembly. The shell assembly is fitted over the outside of the washing tub. An airflow channel is provided on the wall of the washing tub.

[0006] The airflow channel includes a corrugated pipe, and the port of the corrugated pipe is fixed to the exhaust port.

[0007] The housing assembly includes a housing body and an inner liner. The housing body is fitted over the outer side of the inner liner. The exhaust port includes a body air vent on the housing body and a liner air vent on the inner liner.

[0008] The opening of the corrugated pipe is fixed to the air outlet of the inner lining body by a sealing element. An air outlet end cap is provided on the air outlet of the main body. The air outlet end cap has a ventilation hole, which is connected to the corrugated pipe.

[0009] Furthermore, the bellows is provided with a bellows boss at the pipe opening, and the size of the boss is larger than the size of the air inlet of the inner liner and the through hole of the sealing element.

[0010] The corrugated pipe passes through the air inlet of the inner liner and the seal, and the corrugated pipe is tightly fitted with the seal.

[0011] Furthermore, the sealing element has a plurality of fixing pins on the surface opposite to the inner liner, and fixing holes that cooperate with the fixing pins are provided around the air vent of the inner liner, with the fixing pins and fixing holes being interference fit.

[0012] Furthermore, the fixing pin has a gap that extends axially from the end of the fixing pin.

[0013] Furthermore, a ventilation pipe is provided on the side of the air outlet end cap opposite to the inner liner, the inner diameter of the ventilation pipe is not less than the diameter of the ventilation hole, and the outer diameter of the ventilation pipe is interference-fitted with the inner diameter of the corrugated pipe.

[0014] Furthermore, the air vent end cap is fastened to the air vent of the main body.

[0015] Furthermore, the ventilation holes are mesh-like.

[0016] Furthermore, the airflow channel also includes an airflow pipe, which is connected to the washing tub and the corrugated pipe.

[0028] In this utility model, the descriptions involving "first," "second," "upper," and "lower," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," "upper," or "lower" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. Where the technical solutions of the embodiments can be combined, they are all within the protection scope claimed by this utility model.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 4 As shown, a small washer-dryer combo has an exhaust structure. The combo includes a washing tub 100 and a housing assembly 200. The housing assembly 200 is fitted over the washing tub 100. An airflow channel 400 is provided on the tub wall of the washing tub 100. One end of the airflow channel 400 communicates with the washing tub 100, and the other end is connected to the exhaust port of the housing assembly 200. The airflow channel 400 includes a corrugated pipe 410, and the port of the corrugated pipe 410 is fixed to the exhaust port. The housing assembly 200... Component 200 includes a housing body 210 and an inner liner 220. The housing body 210 is fitted over the inner liner 220. The exhaust port includes a main body air outlet on the housing body 210 and a liner air outlet on the inner liner 220. The opening of the corrugated pipe 410 is fixed to the air outlet of the inner liner 220 by a sealing member 500. An air outlet end cap 300 is provided on the main body air outlet. The air outlet end cap 300 is provided with a ventilation hole, which is connected to the corrugated pipe 410.

[0031] The basic structure of the washer-dryer combo of this application can adopt the same structure as a common small washing machine. That is, the washer-dryer combo includes a washing tub 100 and a lid. The washing tub 100 includes an inner tub and an outer tub, and a shell assembly 200 is provided on the outside. The shell assembly 200 includes a shell body 210 and an inner liner 220. The shell body 210 is fitted over the inner liner 220 and they are connected to each other. The washing machine of this application is a small washing machine. Although the washing machine is small, in order to have the same functions as a common washing machine, it needs to have the same various devices and components as a common washing machine. However, due to the limited internal space, an inner liner 220 is provided to support various devices, components, circuit boards, etc. Therefore, the inner liner 220 is provided with various accommodating structures for installing various devices, components, circuit boards, etc. The inner liner 220 has an inner liner top plate, and the shell body 210 has a body top plate. Both the body top plate and the inner liner top plate have top openings, and the two top openings are coaxially arranged. The washing tub 100 is flexibly connected to the inner lining top plate. The connection structure and components can adopt existing technologies and will not be described in detail here. The lid is a hollow box shape, and a control device is installed inside the box to control the operation of the washing machine. A hot air device is also provided. As one embodiment, the hot air device can be a PTC device, and the PTC device is connected to a fan device. An air inlet is provided on the lid, and external air is introduced through the fan device. After heat exchange through the PTC device, the hot air is introduced into the washing tub 100 to dry the clothes. The dried water vapor is discharged to the outside of the washing machine through the airflow channel 400 with the hot airflow. The airflow flows downward from the top of the washing tub 100 and is discharged through the airflow channel 400, forming an overall airflow path.

[0032] To prevent water vapor from entering between the washing tub 100 and the housing assembly 200, causing temperature increases and preventing the repeated intake of airflow mixed with lint, the exhaust port of the airflow channel 400 must be fixed to the housing assembly 200, forming a sealed channel between the interface of the airflow channel 400 and the washing tub 100 and the port connecting the airflow channel 400 and the housing assembly 200. The interface between the airflow channel 400 and the washing tub 100 is sealed, and the port between the airflow channel 400 and the housing assembly 200 is also sealed. Because the washing tub 100 and the inner liner 220 are flexibly connected, to prevent damage to the airflow channel 400 due to severe shaking and vibration of the washing tub 100 during operation, at least a portion of the airflow channel 400 uses a flexible corrugated pipe 410, the port of which is sealed and fixed to the housing assembly 200. As one embodiment, the corrugated pipe 410 can pass through the inner liner vent of the inner liner 220, with its port fixedly connected to the main body vent. However, for ease of assembly, as an alternative implementation, the port of the corrugated pipe 410 can be sealed and fixed to the inner lining vent. To prevent hot airflow from flowing between the washing tub 100 and the housing assembly 200, a vent end cap 300 is provided on the main body vent. The vent end cap 300 is provided with ventilation holes, and the ventilation holes are connected to the port of the corrugated pipe 410 to prevent airflow leakage and ensure that the hot airflow is completely discharged to the outside of the washing machine.

[0033] The exhaust structure of the small washer-dryer combo with the above-described structure improves airflow and drying effect, and avoids temperature rise caused by hot airflow flowing between the washing tub 100 and the shell assembly 200.

[0034] Furthermore, the bellows 410 has a bellows 410 boss at its opening, the size of which is larger than the size of the air vent of the inner liner 220 and the through hole of the sealing member 500; the bellows 410 passes through the air vent of the inner liner 220 and the sealing member 500, and the bellows 410 is tightly fitted with the sealing member 500.

[0035] The bellows 410 and the seal 500 are tightly fitted together to achieve a seal between the air outlet of the inner liner 220 and the bellows 410. After the protrusion of the bellows 410 passes through the air outlet of the inner liner 220 and the seal 500, it is engaged with the surface of the seal 500 facing the housing body 210 to prevent the bellows 410 from falling off.

[0036] Furthermore, the sealing element 500 has a plurality of fixing pins on the surface opposite to the inner liner 220, and fixing holes that cooperate with the fixing pins are provided around the air vent of the inner liner 220, with the fixing pins and fixing holes being interference fit.

[0037] The seal 500 is securely connected to the inner liner 220 by the interference fit between the retaining pin and the retaining hole. Alternatively, the seal 500 can be secured by other methods, such as bonding.

[0038] Furthermore, the fixing pin has a gap that extends axially from the end of the fixing pin.

[0039] The gap in the fixing pin allows for a smaller diameter of the fixing pin, facilitating the installation and removal of the seal 500.

[0040] Furthermore, the air outlet end cap 300 is provided with a ventilation pipe on the side opposite to the inner liner 220, the inner diameter of the ventilation pipe is not less than the diameter of the ventilation hole, and the outer diameter of the ventilation pipe is interference-fitted with the inner diameter of the corrugated pipe 410.

[0041] The air outlet end cap 300 and the bellows 410 are sealed together by the interference fit between the ventilation pipe and the bellows 410, preventing air leakage at the interface.

[0042] Furthermore, the air vent end cap 300 is fastened and connected to the main air vent.

[0043] A locking element is provided on the side surface of the air vent end cover 300 relative to the housing body 210, and a locking groove is provided on the edge of the air vent of the body to cooperate with the locking element. The air vent end cover 300 is fixed by the locking element and the locking groove.

[0044] Furthermore, the ventilation holes are mesh-like.

[0045] Alternatively, the ventilation holes can be made into a grille shape.

[0046] Furthermore, the airflow channel 400 also includes an airflow pipe 420, which is connected to the washing tub 100 and is also connected to the corrugated pipe 410.

[0047] The airflow channel 400 can be entirely made of a bellows 410. However, the longer the bellows 410, the greater its flexibility. Small washing machines have compact internal structures, and to prevent interference between the bellows 410 and other components, it needs to be fixed. Therefore, preferably, a portion of the airflow channel 400 is made of a rigid structure. In this embodiment, the airflow channel 400 is formed by connecting the bellows 410 to a rigid airflow pipe 420.

[0048] Furthermore, the airflow duct 420 is integrally formed with the washing tub 100.

[0049] The airflow duct 420 is preferably integrally formed with the washing tub 100. Specifically, a duct connected to the washing tub 100 is formed on the outside of the washing tub 100 using the same material.

[0050] Furthermore, the all-in-one machine also includes a hot air device, which has an air outlet located at the opening of the washing tub 100. The airflow duct 420 is connected to the washing tub 100 below it.

[0051] As described above, the hot airflow after heat exchange through the hot air device enters the washing tub 100 from above and passes over the clothes to dry the moisture in the clothes. This causes the moisture to form water vapor, which enters the airflow channel 400 from below the washing tub 100 and is discharged to the outside of the washing machine with the airflow. This avoids the water vapor flowing backward or irregularly, which would cause the clothes to become wet again, thus improving the drying effect of the clothes.

[0052] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
