Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, in particular to a washing machine outer barrel front cover and a washing machine comprising the outer barrel front cover. Background Art

[0002] Wall-mounted washing machines, as miniature drum washing machines, are popular because of their compact size, small footprint, and flexible use. The drying structure design of existing wall-mounted washing machines generally involves blowing heated hot air into the inner drum to heat the clothes. The hot air is then converted into hot air with a high water content and discharged from the inner drum. This air then enters the condenser tube inside the housing connected to the outer drum for heat exchange, forming condensed water before being discharged. In this structure, on the one hand, the hot air inlet is located on the sealing ring between the outer drum and the front cover of the outer drum. To ensure the air intake, the size of the air inlet is dictated by the design requirements of the sealing ring width, requiring the sealing ring to be appropriately widened, which increases the processing and installation complexity. On the other hand, the condensation system not only increases the structural complexity of the wall-mounted washing machine, but is also economically impractical for wall-mounted washing machines with relatively small laundry volumes.

[0003] Based on this, the present application proposes an outer drum front cover and a wall-mounted washing machine with a changed hot air inlet structure to solve the current practical problems. Utility Model Content

[0004] The utility model provides a washing machine outer drum front cover and a washing machine including the outer drum front cover. Hot air is conveniently introduced, and the hot air inlet structure is directly integrated into the outer drum front cover, avoiding the design requirement of widening the sealing ring. The installation and use are more flexible and convenient, the condensation system is omitted, and the overall structure of the wall-mounted washing machine is simplified. It is economical and practical, and can solve the problems existing in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A front cover of a washing machine outer drum comprises a front cover body in the shape of an annulus, the front cover body comprising a central annular side wall and a mounting portion arranged on the outer periphery of the rear end of the annular side wall, an air inlet is arranged on the annular side wall, an air inlet duct protruding outward from the annular side wall is connected to the outside of the air inlet, an air inlet duct entrance is arranged on the rear side of the air inlet duct, and an air inlet duct outlet is arranged on the side where the air inlet duct is connected to the annular side wall; the front cover body and the air inlet duct are integrally formed.

[0007] Furthermore, the air inlet duct includes a rear cover and a front cover assembled with the rear cover, and the annular side walls at both ends of the air inlet extend outward along the front side of the mounting portion and close to form the rear cover; the air inlet duct inlet is arranged on the rear side of the rear cover, and the air inlet duct outlet is formed on the right side of the assembled front cover and rear cover, and the air inlet duct outlet is sealed and connected to the air inlet accordingly.

[0008] Furthermore, the front cover body is sealed and connected to the front end of the washing machine outer tub; and the hot air duct is detachably connected to the rear end of the air inlet. The air transported by the hot air duct is transported into the air inlet through the air inlet inlet, and then discharged into the washing machine outer tub through the air inlet outlet and the air inlet.

[0009] Furthermore, the air inlet is an air inlet of a certain length arranged along the circumference of the annular side wall.

[0010] Furthermore, the air inlet is arranged corresponding to the air inlet duct outlet.

[0011] Furthermore, the aforementioned mounting portion is a mounting plate, which is used to assemble the outer barrel front cover and the outer barrel, the casing and the door seal.

[0012] The utility model also provides the following technical solutions:

[0013] A washing machine comprises the above-mentioned washing machine outer drum front cover.

[0014] Furthermore, it includes a casing, an outer barrel and a front cover of the outer barrel arranged at the front end of the outer barrel. A drying mechanism is arranged on the casing above the outer barrel, and the drying mechanism is connected to the air inlet of the air inlet duct through the air duct; an exhaust outlet is arranged on the casing above the rear of the outer barrel; and a door seal is installed on the front side of the front cover of the outer barrel.

[0015] Furthermore, the drying mechanism includes a fan, a heater, and an air duct arranged between the fan and the heater, and the heater outlet is connected to the air duct.

[0016] Furthermore, an exhaust pipe is connected to the outer end of the exhaust port.

[0017] Furthermore, the washing machine is a wall-mounted washing machine.

[0018] Beneficial effects of the utility model:

[0019] The front cover of the outer drum of the washing machine of the present invention has an air inlet opened on the annular side wall and connected to the air inlet duct. The air inlet duct and the front cover body are designed as an integrated whole, which is flexible in processing and manufacturing and easy to install and use. The existing air inlet which is generally set on the sealing ring is replaced by being opened on the front cover of the outer drum, avoiding the additional requirement of widening the design of the sealing ring connected to the air inlet, and the structure is more reasonable.

[0020] Based on the consideration of the small size and capacity of the wall-mounted washing machine and the usage environment, in addition to home use, it is also necessary to install it in outdoor facilities such as ships and RVs. The condensation system is eliminated, and the hot air that heats the clothes enters the inner drum through the aforementioned air inlet to heat the clothes. After heating, the water-containing hot air is directly discharged to the outside through the exhaust port, which makes the structure more streamlined and the economic and practicality improved.

[0030] Example 1

[0031] like Figure 1-4As shown, the front cover of the washing machine's outer drum comprises an annular front cover body 1, which includes a central annular sidewall 101 and a mounting portion 102, or mounting plate, located on the outer periphery of the rear end of the annular sidewall. An air inlet 2 is provided on the upper left side of the annular sidewall. The air inlet is an opening extending a certain length along the circumference of the annular sidewall, and is connected to an air inlet duct 103 protruding from the annular sidewall on its outer side. The air inlet duct is formed by a rear cover 3 and a front cover 4 connected thereto. An air inlet inlet 5 is provided on the rear side of the air inlet duct, and an air inlet outlet 6 is provided on the side where the air inlet duct connects to the annular sidewall.

[0032] The above-mentioned air inlet duct includes a rear cover and a front cover assembled with the rear cover. The outer sides of the annular side walls 101 at both ends of the air inlet extend along the front side surface of the mounting portion and close to form the rear cover; the air inlet duct inlet 5 is on the rear side of the rear cover, and the air inlet duct outlet 6 is formed on the right side of the assembled front cover and rear cover, and the air inlet duct outlet is correspondingly sealed and connected to the air inlet 2.

[0033] The front cover is sealed and attached to the front end of the washing machine's outer tub. A hot air duct is detachably connected to the rear end of the air inlet. Air from the hot air duct is transported through the air inlet into the air inlet, and then discharged into the washing machine's outer tub through the air inlet outlet and air inlet.

[0034] The outer barrel front cover of the above structure replaces the existing hot air inlet located on the sealing ring between the outer barrel front cover and the outer barrel with a hot air inlet directly opened on the annular side wall of the outer barrel front cover. On the one hand, it avoids the need for widening the sealing ring required in the existing technology, and on the other hand, it ensures a more stable structure of the air inlet duct and the air inlet, is more convenient to connect with the drying system, and is easy to manufacture and install.

[0035] See also Figure 5 , shows the specific connection between the outer drum front cover and the drying system. Specifically, fan 7 is connected to heater 9 via air duct 8. The air outlet of heater 8 is connected to the air inlet 5 of the air inlet duct via air duct 10. Hot air entering the air inlet duct enters the air inlet through the air inlet outlet, heating the clothing in the inner drum.

[0036] Example 2

[0037] See also Figure 6 A wall-mounted washing machine includes the outer tub front cover of Example 1. Specifically, the wall-mounted washing machine includes a housing 11, an outer tub 12, and an outer tub front cover 13 disposed at the front end of the outer tub. A drying mechanism is disposed above the outer tub, comprising a fan, a heater, an air duct, and the like. An exhaust vent 14 is disposed on the housing at the rear top of the outer tub 12. A door seal is mounted on the housing in front of the outer tub front cover.

[0038] The working principle of this utility model:

[0039] The hot air blown out by the drying system of the wall-mounted washing machine enters the air inlet 103 through the air inlet inlet 5, and is blown into the outer tub 12 through the air inlet outlet 6 and the air inlet 2 provided on the annular side wall 101, and then heats the clothes in the inner tub through the opening on the inner tub wall. After heating, the hot air with high water content is directly discharged through the exhaust port 14 at the top of the outer tub or discharged to the outside through the external exhaust pipe connected to the exhaust port.

[0040] The above specific implementation methods cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or transformation made to the implementation methods of the present utility model falls within the protection scope of the present utility model.
