Description

Clothes dryer

The present invention relates to a clothes dryer that can separate and dry clothes by using a basket.

In general, a clothes dryer is a device for drying clothes by blowing hot air into a drum into which wet clothes are put. The clothes dryer may be classified into an exhaust dryer and a condensation dryer according to a method of processing the humid air discharged from the drum in the process of drying the clothes.

In the exhaust dryer, the clothes heated by the heater are supplied into the drum to dry the clothes, and the humid air discharged from the drum is exhausted to the outside of the dryer. This method eliminates the need for a separate means to condense the moisture since the moisture removed from the garment is discharged out of the dryer together with the air.

The condensation dryer is circulated along a circulation passage configured to allow air heated by the heater to pass through the drum, in which the moisture contained in the air is condensed or removed.

In some cases, it is necessary for the user to optionally separate and dry these garments. For example, ordinary users do not prefer to mix sensitive clothing with other clothing in the case of sensitive clothing such as underwear or newborn baby items. However, the conventional clothes dryer separates the clothing because the space in which the clothing is accommodated is limited to the drum. It could not be dried. Therefore, there is a problem that only sensitive clothes are put into a drum and dried out, and then the clothes dryer is operated again to dry other clothes.

In addition, since the drying speed of clothes varies depending on the material, when the clothes of the drying material and the clothes of the late drying material are put together in the drum, drying of all the clothes in the drum is completed. Clothing made of a fast material may cause a problem of over-drying. Therefore, the clothes of the drying material is required to stop the operation of the dryer and take out before the drying operation is completed. However, in the conventional clothes dryer, since all the clothes are mixed in the drum, there is a hassle for the user to select and pull out the clothes which have been completely dried.

The problem to be solved by the present invention is provided with a basket that can separate and dry the clothing that needs to be separated and dried other clothing and the drum, the basket is rotated so that the position of the clothing can be changed in the basket To provide a clothes dryer. In particular, the rotation of the basket is linked with the rotation of the drum, to provide a clothes dryer does not need to install a separate motor for rotating the basket.

The present invention relates to a clothes dryer for supplying hot air into a drum rotatably provided to dry clothes put in the drum.

The clothes dryer includes a casing having a front panel in which the drum is disposed inward, a front panel having an inlet communicating with the inside of the drum, and a basket inserted into the inlet. The basket forms a space in which clothing is accommodated separately from the drum.

The basket may be supported by the front panel while being inserted into the inlet. The basket is provided with a plurality of through holes so that hot air supplied into the drum flows into the space.

A door is rotatably coupled to the front panel, and the entrance of the basket is opened and closed by the door.

The basket includes a receiver supporter detachably coupled to the circumference of the inlet, a receiver forming the space and rotatably coupled to the receiver supporter, and the radially spaced position from the center of rotation of the receiver. And a driven protrusion projecting outwardly of the receiver.

The receiver supporter may be fitted to the inlet, and may be separated from the inlet by a user's operation.

The drum is provided with a drive arm. The drive arm is rotated integrally with the drum. When the drum rotates, the receiver is rotated by contacting the driving arm with the driven protrusion.

Clothes dryer according to another aspect of the present invention, the basket is provided rotatably on the door. The basket is located at least partially in the drum with the door closed. The basket is provided with a plurality of through holes so that hot air supplied into the drum flows into the space.

The basket includes a driven protrusion projecting out of the space in which the garment is received at a position spaced from the center of rotation. The drum is provided with a drive arm. When the drum rotates, the basket is rotated by contacting the driving arm with the driven protrusion.

The clothes dryer of the present invention has an effect of being able to dry separately from clothes put into a drum by putting clothes (eg, underwear) that require separate drying into a basket. In particular, since the basket is rotated, there is an effect that the clothes contained in the basket can be evenly dried.

Rotation of the basket is linked with rotation of the drum, and in particular, since the basket is rotated by a driving arm that is integrally rotated with the drum, there is an advantage that there is no need to install a separate motor for rotating the basket.

In addition, the basket can be detachably coupled to the inlet formed in the casing, in this case, only when the clothes need to be separated and dried, the user can selectively install the basket, there is an effect that the convenience of use is formed. . In particular, in order to inject clothes into the drum, the inlet should be opened. In this case, by simply removing the basket, it is not inconvenient to use even during normal drying using the drum. In addition, since the basket can be separated from the casing, it is convenient to carry the basket in the state in which the clothes are put in place and move it as it is.

Alternatively, the basket may be provided in the door. In this case, opening the door improves the convenience of use because the basket is not an obstacle to feeding clothes into the drum.

In addition, in the clothes dryer of the present invention, when clothes are put into both the drum and the basket and dried, the clothes are put into the basket to be dried quickly and manually or a predetermined algorithm is completed before the drying operation is completed. As a result, the operation may be automatically paused, the clothes in the dried basket may be taken out, and the operation may be continued again to complete drying of the clothes in the drum. Such a method is overdrying the clothes (when the drying operation is set to complete drying of all the clothes) or undrying, as compared with a method of putting the fast drying clothes and the late drying clothes in the drum at once and drying them. There is an effect that can be prevented from occurring (when the drying operation is set corresponding to the clothes which dry quickly).

The electrode sensor may include an anode and a cathode spaced apart from each other. The positive electrode and the negative electrode are exposed into the baskets 50a and 50b. When clothes are in contact with the positive electrode and the negative electrode when the baskets 50a and 50b are rotated, both electrodes are connected by the moisture contained in the clothes to form a closed circuit. At this time, since the resistance value is changed according to the amount of moisture included in the clothes, the current value flowing through the circuit is different, and the controller (not shown) may calculate the dryness of the clothes based on the current value.

The control unit not only determines the degree of drying, but also controls various electrical appliances constituting the clothes dryer. The control unit may include a central processing unit (CPU) and a memory for storing data in a form readable by the central processing unit.
