Description

Technical Field

[0001] The present invention relates to a clothes dryer having a structure in which a door port is mounted on a cylindrical flange portion of a drum bracket of a clothes removal port. Background Art

[0002] The clothes dryer has the following structure: a drum bracket made of a metal plate and provided with a warm air outlet is arranged on the inner side surface of the front plate of the main body provided with a clothes outlet, a cylindrical door port made of resin is assembled to the cylindrical flange portion formed in the opening of the drum bracket, and the door port is attached to the clothes outlet (Japanese Patent Application No. 2018-7827, Figure 1 The door port protects the cylindrical flange of the drum holder made of sheet metal from being exposed to the clothing removal port, preventing direct contact with the hands. The lower portion of the door port has a trumpet-shaped portion that expands toward the rear surface of the drum to facilitate the removal of clothing from the drum.

[0003] In the clothes dryer, a gap is provided between the cylindrical flange portion of the drum bracket and the door port to facilitate smooth installation and removal of the door port during assembly or maintenance. To facilitate assembly on the drum bracket, the horn portion of the door port is formed only within a certain range at the lower portion of the door port. Therefore, as the horn portion of the door port expands into a horn shape, the gap between the cylindrical flange portion of the drum bracket and the door port narrows. There are cases where clothing may become caught in the narrowed gap portion of the horn portion due to the rotation of the drum. In this case, there are problems such as warm air continuing to locally contact clothing or making it difficult to remove clothing. Summary of the Invention

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a clothes dryer having a structure capable of preventing clothes from being caught on a horn portion of a door port.

[0005] The clothes drying machine involved in the present invention,

[0006] A drum bracket made of a metal plate is provided on the inner side surface of the front plate of the main body provided with the clothing removal outlet. The drum bracket rotatably supports the front surface opening edge of the drum and is provided with a warm air outlet. A cylindrical door port made of resin is assembled with a gap on the inner peripheral side of the cylindrical flange portion formed in the opening of the drum bracket and is installed on the clothing removal outlet.

[0007] The lower part of the door port is formed with a trumpet portion that expands in diameter toward the rear surface side of the drum.

[0008] In the gap, a barrier portion extending in the direction of the central axis of the gate port is provided near a circumferential end portion of the flared portion located on the rear side in the drum rotation direction.

[0009] With this structure, the obstruction prevents clothing from entering the gap in the horn due to the rotation of the drum. This prevents clothing from getting caught in the horn at the door opening. This prevents clothing from getting caught in the gap in the horn, causing warm air to locally and continuously contact clothing and making it difficult to remove clothing.

[0010] The obstruction is set at a height extending radially along the door port, allowing the door port to be attached and detached from the drum holder. This prevents the obstruction from hindering attachment and detachment of the door port from the drum holder, allowing for smooth assembly and maintenance of the door port. This prevents clothing from snagging on the bell portion of the door port, while ensuring smooth assembly and operability of the door port. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Hereinafter, with reference to the accompanying drawings, embodiments of the present invention will be described. Figure 1 While explaining.

[0047] like Figure 1 As shown, the clothes dryer 1 of the embodiment comprises a rectangular box-shaped main body 10 and a door 13 that freely opens and closes over a clothes removal opening 12 provided on a front panel 11 of the main body 10. In this specification, the side facing the door 13 is referred to as the front surface of the clothes dryer 1. The depth direction of the main body 10 when viewing the clothes dryer 1 from the front surface is referred to as the front-to-back direction. The direction that intersects the front-to-back direction in the horizontal direction is referred to as the left-to-right direction. The direction perpendicular to the front-to-back direction and the left-to-right direction in the height direction is referred to as the up-down direction.

[0048] A cylindrical drum 2 with an opening 21 on its front surface and housing laundry M is disposed horizontally within the main body 10. An exhaust port 23 is formed on the rear surface 25 of the drum 2, and an exhaust duct 14 is provided at the rear of the main body 10, communicating with the exhaust port 23 of the drum 2. An air supply port 15 with a filter is formed on the bottom plate of the lower surface of the main body 10. An air supply and exhaust fan 3 is disposed at the rear of the drum 2. The air supply and exhaust fan 3 exhausts air from the drum 2 through the exhaust port 23 into the exhaust duct 14, and supplies air from the air supply port 15 into the drum 2. While the drum 2 and the air supply and exhaust fan 3 are driven by a shared motor (not shown) via separate belts, they may alternatively be driven by separate motors. Furthermore, a burner 4, serving as a heating unit, is disposed within the main body 10 in the air supply passage from the air supply port 15 to the drum 2. Thus, the exhaust gas from the burner 4 is supplied into the drum 2 as warm air along with the air. Furthermore, the heating means is not limited to the burner 4, and may be an electric heater, a heat exchanger for circulating warm water, or the like.

[0049] Reference Figure 1 as well as Figure 2 A drum holder 5 made of sheet metal is disposed on the inner side of the front panel 11 of the main body 10, which is provided with a clothing outlet 12. The drum holder 5 comprises a circular plate portion 51 with an opening 53 at the center; a short cylindrical drum receiving portion 52 protruding forward from the outer periphery of the plate portion 51; and a short cylindrical flange portion 54 protruding forward from the opening 53 of the plate portion 51.

[0050] The drum 2 is rotatably supported by the fixed wall 16 in the main body 10, while the drum shaft 24 fixed to the rear surface 25 is rotatably supported by the front surface opening edge 22 of the drum holder 5. A plurality of warm air outlets 55 communicating with the air supply passage are provided within a certain range at the lower portion of the plate surface 51 of the drum holder 5. Warm air is supplied from the warm air outlets 55 into the drum 2. As a result, the drum holder 5 is heated by the warm air. The opening 53 of the drum holder 5 has an opening diameter that is substantially the same as the clothing removal outlet 12 of the front plate 11 of the main body 10 and is arranged concentrically with the clothing removal outlet 12.

[0051] A cylindrical door port 6 made of resin is assembled on the inner circumference of a cylindrical flange portion 54 formed in an opening 53 of the drum holder 5. The front portion of the door port 6 is attached to the clothing removal opening 12 of the front plate 11. The door port 6 is provided to protect the cylindrical flange portion 54 of the drum holder 5 made of sheet metal from being exposed at the clothing removal opening 12 so as to prevent direct contact with hands.

[0052] To facilitate smooth installation and removal during assembly and maintenance, the door port 6 is mounted with a gap c relative to the cylindrical flange 54 of the drum holder 5. Furthermore, the lower portion of the door port 6 is formed into a trumpet portion 61, which expands in diameter toward the rear surface 25 of the drum 2 in a trumpet-like manner to facilitate removal of the laundry M from the drum 2. This trumpet portion 61 is formed only within a certain range of the lower portion to facilitate assembly of the door port 6 to the drum holder 5.

[0053] However, as the trumpet portion 61 of the door port 6 expands into a trumpet shape, the gap c between the cylindrical flange portion 54 of the drum holder 5 and the door port 6 narrows. Consequently, the clothing M may become caught in the narrowed gap c of the trumpet portion 61 due to the rotation of the drum 2. In this case, the warm air may continue to contact the clothing M locally, or it may be difficult to remove the clothing M.

[0054] In this embodiment, if Figure 3 、 Figure 4 As shown, at the door port 6, a rib 7 is provided as an obstruction portion at the circumferential end portion 61a of the trumpet portion 61 located on the rear side in the drum rotation direction A. The rib 7 is provided on the outer peripheral surface of the door port 6 in such a manner as to extend along the central axis direction of the door port 6 at a position circumferentially near the front of the trumpet portion 61 when viewed from the rear side in the drum rotation direction A. The rib 7 is provided at the gap c between the cylindrical flange portion 54 of the drum bracket 5 and the door port 6. In addition, the position where the rib 7 is provided is not limited to the position circumferentially near the front of the trumpet portion 61. Figure 5 As shown, the position of the circumferential end portion 61a ( Figure 5 The rib 7a in the middle) or the circumferential position of the circumferential end portion 61a close to the flared portion 61 side ( Figure 5 The rib 7 can be provided near the circumferential end 61a, as in the rib 7b in FIG. Furthermore, the rib 7 only needs to be provided near the circumferential end 61a. Therefore, the width of the rib 7, i.e., the width of the rib 7 in the drum rotation direction A, can be formed to be a wide width extending from the circumferential front position, including the circumferential end 61a, to the circumferential position near the flared portion 61a. Furthermore, the width of the rib 7 can be formed to be an appropriate width within the range from the circumferential front position to the circumferential position near the flared portion 61a. Setting the rib 7 to a wide width improves the strength of the rib 7.

[0055] According to the above structure, the ribs 7 can prevent the clothes M from entering the gap c of the trumpet portion 61 due to the rotation of the drum 2. Therefore, the clothes M can be prevented from being caught on the trumpet portion 61 of the door port 6. As a result, the clothes M can be prevented from being caught in the gap c of the trumpet portion 61, which would cause the warm air blown out from the warm air outlet 55 at the bottom of the drum holder 5 to partially and continuously contact the clothes M, or make it difficult to remove the clothes M.

[0056] Reference Figure 4 The rib 7 is provided at the rear of the door port 6 within a range overlapping the cylindrical flange portion 54 of the roller holder 5. The rib 7 is formed to extend forward from a position slightly forward of the rear end of the door port 6, but may alternatively be formed to extend forward from the rear end of the door port 6. The height of the rib 7 is set to extend radially in the door port 6 and to be equal to or slightly lower than the dimension of the gap c. The length of the rib 7 is set to be shorter than the protruding length of the cylindrical flange portion 54 of the roller holder 5, but may alternatively be equal to or shorter than the protruding length of the cylindrical flange portion 54.

[0057] Thus, the door port 6 can be smoothly attached and detached from the drum bracket 5 without being obstructed by the ribs 7, and the door port 6 can be smoothly attached and detached during assembly or maintenance of the door port 6. Therefore, it is possible to prevent clothing M from getting caught on the horn portion 61 of the door port 6, and to ensure good assembly operability of the door port 6.

[0058] In addition, the present invention is not limited to the above-described embodiment, and various modifications can be implemented within the scope of the claims.

[0059] For example, the rib 7 serving as the obstruction portion may be provided so as to protrude from the inner circumferential surface of the cylindrical flange portion 54 of the roller bracket 5 rather than from the door port 6. The rib 7 (obstruction portion) is not limited to being provided integrally with the door port 6 or the roller bracket 5, but may be provided so as to be attachable and detachable using various coupling methods.

[0060] In addition, in devices in which the drum 2 rotates forward and reverse, the ribs 7 (obstructions) can be provided near the left and right circumferential ends 61a and 61b of the flared portion 61. Furthermore, even if the drum 2 rotates only in one direction, the ribs 7 (obstructions) can be provided near the left and right circumferential ends 61a and 61b of the flared portion 61.
