Description

Garment treatment device including filter cover

[0001] The present invention relates to a filter cover and a garment treatment device including the same. More specifically, the invention relates to a garment treatment device including a filter cover.

[0002] A garment treatment device is a device that can treat garments, such as a washing machine or dryer.

[0003] In general, a washing machine is a device that uses the driving force of a driving motor to agitate laundry, washing water, and detergent placed inside a drum together to wash them through friction between them. There are two types of washing machines: a drum washing machine that washes laundry by lifting the laundry upward along the inner surface of the rotating drum and dropping it when the rotating drum is rotated forward and backward about a horizontal axis by arranging the rotating drum horizontally, and a vertical axis washing machine that washes laundry by utilizing the water current generated by the pulsator when the rotating drum having a pulsator inside is rotated forward and backward about a vertical axis by arranging the rotating drum vertically.

[0004] Drum-loading or vertical-axis washing machines are equipped with filters to filter out foreign substances such as lint generated during the washing process. The filters may be covered by filter covers for user replacement.

[0005] These filter covers are usually made of injection molded parts and colored steel plates attached to match the housing (counterpart).

[0006] However, the filter cover, which is composed of injection parts and attachments such as color steel plates, has durability problems such as the color steel plates falling off.

[0007] One aspect of the present disclosure provides a garment treatment device including a filter cover using a thermal transfer method.

[0008] One aspect of the present disclosure provides a garment treatment device with an improved filter cover. Another aspect of the present disclosure provides a garment treatment device that can enhance the aesthetic appeal of the exterior and diversify the design by applying a thermal transfer process to the filter cover.

[0009] One aspect of the present disclosure provides a clothing treatment device capable of preventing thermal deformation so as to apply a thermal transfer method to a filter cover.

[0010] One aspect of the present disclosure provides a clothing treatment device capable of improving durability so that the cover does not come off or the like even when subjected to external impacts that may occur when opening or closing the filter cover.

[0011] The technical problems to be achieved in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0012] A clothing treatment device according to the invention comprises a housing having a laundry inlet for loading or unloading laundry, a door for opening and closing the laundry inlet, a tub provided inside the housing to store washing water, a drum that rotates inside the tub and performs respective operations according to washing, rinsing, and dehydration processes for the laundry, and a filter cover provided to cover a filter through an opening formed in at least a portion of the housing, wherein the filter cover comprises a first member provided by injection molding, and a second member attached to the first member by a heat transfer method and provided to be exposed to the outside.

[0013] For example, by applying a heat transfer method to the filter cover, the aesthetics of the appearance can be improved and the design can be diversified.

[0014] For example, by applying a thermal transfer method to a filter cover, the number of parts can be reduced and the process can be shortened.

[0015] For example, durability can be improved to prevent the cover from being peeled off or other damage that may occur when opening or closing the filter cover.

[0016] For example, thermal deformation can be prevented to prevent warping of injection molded parts during a thermal transfer process.

[0017] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

[0176] The above jig device (900) is preheated before the pressing process of the roller (700). The jig device (900) heats the jig device (900) that touches the rear surface (111b) of the first member (110) to a temperature of 30 degrees.

[0177] In this way, by heating the jig device and increasing the temperature of the jig device, warping, shrinkage and appearance defects caused by pressure from the high-temperature roller during the heat transfer process can be prevented, and the amount of deformation can be minimized.

[0178] The manufacturing method of the above clothing treatment device is such that the first member (110) is formed by an injection device, the first member (110) is installed in a jig device (900), the jig device (900) is heated, and a second member (120) is attached to the front surface (111a) of the first member (110) by a heat transfer method to form a filter cover (100).

[0179] By applying a heat transfer technique to a filter cover, the aesthetics of the exterior can be enhanced and the design can be diversified. According to the present disclosure, a filter cover has a structure that can prevent thermal deformation so that the heat transfer technique can be applied, and durability can be improved so that the cover does not peel off or otherwise become damaged by external impacts that may occur when opening and closing the filter cover.

[0180] The first member (110) includes a plate-shaped first member body (111) including a rear surface (111b) opposite the front surface (111a) and a connecting surface (111c) connecting the front surface (111a) and the rear surface (111b) to form a side surface, and a protrusion (200) provided so as to protrude at least a portion from the rear surface (111b) of the first member body (111).
