[0028] DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0033] For example, a drum washing machine uses a return air mechanism to maintain pressure balance when the water pipe fills the drum during the wash cycle. This mechanism typically consists of a return air bellows, one end of which is fixed to the drum and the other to the water tank to prevent splashing. This mechanism requires multiple materials and requires installation at both ends, making installation and connection complex.

[0034] To this end, combined Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the embodiment of the present application provides an outer tub 10 for washing equipment, comprising:

[0035] The barrel body 100 has an exhaust port 110 at its upper portion;

[0036] The exhaust pipe 200 includes a first pipe section 210 and a second pipe section 220; the first pipe section 210 and the second pipe section 220 are connected and extend in different directions; the first pipe section 210 is arranged at the exhaust port 110 to be connected to the interior of the barrel body 100 through the exhaust port 110; the second pipe section 220 is connected to the atmospheric environment, and the outlet 221 of the second pipe section 220 is set upward.

[0037] In the technical solution of the embodiment of the present application, the first pipe section 210 of the exhaust pipe 200 is arranged at the exhaust port 110, so that when the washing equipment starts to fill water into the barrel, the gas inside the barrel body 100 is guided into the exhaust pipe 200, and then discharged into the atmospheric environment through the outlet 221 of the second pipe section 220; since the first pipe section 210 and the second pipe section 220 extend in different directions, and the outlet 221 of the second pipe section 220 is arranged upward, it can be avoided that water splashes out of the barrel when the washing equipment is dehydrating; therefore, the technical solution of the embodiment of the present application does not require the second pipe section 220 to be installed on the water box, which can reduce the complexity of the installation of the exhaust pipe 200 and simplify the installation.

[0038] like Figure 1 and Figure 5 As shown, since the outlet 221 of the second pipe section 220 is directly connected to the outside air, it does not need to be connected to the water box, so there is no need to set up structures such as bellows, which reduces the number of parts and reduces investment costs.

[0039] As an optional implementation of the above embodiment, the first pipe section 210 is arranged away from the barrel body 100 along a first direction, and the second pipe section 220 extends along a second direction; the first direction and the second direction are arranged at an obtuse angle. It is easy to understand that when water is poured into the barrel body 100, the gas flows upward, and therefore the exhaust port 110 of the outer barrel 10 is arranged in the upper area of the barrel body 100 to facilitate exhaust. In this embodiment, the first pipe section 210 is arranged away from the barrel body 100 along the first direction, and the extension direction of the second pipe section 220 is arranged at an obtuse angle to the first direction, so that during washing and dehydration, water splashed into the exhaust pipe 200 can flow back into the barrel body 100 under the action of gravity, avoiding water splashing.

[0040] As an optional implementation of the above embodiment, Figure 4 and Figure 8 As shown, the first direction is the vertical direction. That is, the first direction extends away from the entire body in the opposite direction of gravity, while the second direction is set at an obtuse angle α thereto, so that the second pipe section 220 extends upwardly and tiltedly. This allows water splashed into the exhaust pipe 200 to flow back into the barrel body 100 under the action of gravity during washing and dehydration, thereby preventing water from splashing out.

[0041] In an embodiment, the obtuse angle between the first direction and the second direction is preferably set between 120° and 165°.

[0042] As an alternative to the above embodiment, the exhaust pipe 200 further includes a third pipe segment 230, the opposite ends of which connect the first pipe segment 210 and the second pipe segment 220. In this embodiment, the third pipe segment 230 serves to transition between the first pipe segment 210 and the second pipe segment 220. When water splashes into the exhaust pipe 200, the third pipe segment 230 can prevent the water from entering the second pipe segment 220, thereby preventing water from splashing out.

[0043] In an embodiment, the exhaust pipe 200 is a structural component.

[0044] As an optional implementation of the above embodiment, Figure 1 and Figure 5 As shown, the barrel body 100 is provided with a mounting joint 300 communicating with the exhaust port 110, and the first pipe section 210 is detachably connected to the mounting joint 300. The mounting joint 300 is detachably connected to the first pipe section 210, making it easy to install the first pipe section 210 on the barrel body.

[0045] As an optional implementation of the above embodiment, Figure 6 、 7 and Figure 8As shown, an elastic clip 250 is provided on the outside of the first pipe section 210; the mounting joint 300 has a mounting channel and a slot or hole 320 formed on the wall of the mounting channel. The first pipe section 210 is inserted into the mounting channel, and the elastic clip 250 is snapped into the slot or hole 320. With this structure, the installer can insert the first pipe section 210 into the mounting channel. Once the elastic clip 250 enters the mounting channel, pressure is applied. When the elastic clip 250 aligns with the slot or hole 320, the elastic clip 250 snaps into place due to its elastic force, securing the exhaust pipe 200 to the barrel 100. To remove and clean the exhaust pipe 200, the installer can press the elastic clip 250 to disengage it from the slot or hole 320, allowing the exhaust pipe 200 to be removed. This structure facilitates both removal and installation.

[0046] As an optional implementation of the above embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, the first pipe section 210 is sleeved onto the mounting joint 300. In some embodiments, the exhaust port 110 and the mounting joint 300 can be connected via a flange connection, a threaded connection, or other connection structure. In some embodiments, a sealing ring can be provided within the first pipe section 210. The assembly force of the first pipe section 210 and the mounting joint 300 causes the sealing ring to deform, thereby increasing the tightening force and preventing water from leaking out between the two.

[0047] As an optional implementation of the above embodiment, a first connecting hole 240 is provided on the outer side of the first pipe section 210, and a second connecting hole 310 is provided on the outer side of the mounting joint 300; the first connecting hole 240 and the second connecting hole 310 are connected by a connecting piece. Figure 4 As shown, in this embodiment, the first pipe section 210 is sleeved onto the mounting joint 300; the connecting piece is connected to the first connecting hole 240 outside the first pipe section 210 and the second connecting hole 310 outside the mounting joint 300, so that the exhaust pipe 200 is fixed.

[0048] In this embodiment, a first protrusion is provided on the outside of the first pipe section 210, and a first connection hole 240 is provided on the first protrusion. A second protrusion is provided on the outside of the mounting joint 300, and a second connection hole 310 is provided on the second protrusion. The connecting member can be a threaded member, and the first connection hole 240 and the second connection hole 310 are connected by the threaded member.

[0049] As an alternative embodiment to the above embodiment, a reinforcement column is provided on the outside of the mounting adapter 300, extending from the barrel body 100 away from the barrel body 100. In this embodiment, the reinforcement column provided on the outside of the mounting adapter 300 can improve the stability of the mounting adapter 300. In this embodiment, there can be multiple reinforcement columns, each of which is axially arranged on the outside of the mounting adapter 300.

[0050] In an embodiment, the mounting joint 300 and the barrel body 100 are integrally formed.

[0051] The present application also provides a washing machine comprising an outer tub 10. The outer tub 10 utilizes some or all of the technical solutions of the aforementioned embodiments, and thus, the washing machine possesses some or all of the technical advantages of the aforementioned embodiments. In the embodiments, the washing machine is typically a drum-type washing machine, a shoe washer, or a washer-dryer. The washing machine also includes an inner tub, which is disposed within the outer tub 10.

[0052] The above description is merely an optional embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the contents of the present application specification and drawings under the application concept of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
