Description

Duct structure of drawer type washing machine

The present invention relates to a washing machine, and more particularly, to a technology in which a drawer function for allowing the outer and outer draws of the washing machine to the washing machine is added, and a flow path structure for securing the connection and fixing of the flow path part during the withdrawal is added.

In general, a washing machine is a device that peels contaminants by applying energy such as impact to laundry, and may be divided into a pulsator type washing machine and a drum type washing machine according to a method of applying energy to laundry. That is, the laundry is impacted by the pulsator, or the laundry is dropped by rotating the drum to impact the laundry. And the action of the detergent is added to this is done washing.

On the other hand, the above-mentioned washing machine is a situation that is installed in the porch or toilet that is less noticeable from the vibration of the washing tank and the place where the damage is less noticeable to the person who is a particular place.

In other words, the pulsator type washing machine has a structure in which an inner tank, which is a washing tank, is placed perpendicular to the ground, in which the washing machine has a certain height to satisfy the washing capacity. Due to the opening and closing structure, it is not aesthetically pleasing to use in a general kitchen or living room other than the specific place (porch or toilet) mentioned above, and other equipment such as a microwave oven or a TV cannot be placed on top of the washing machine. It was difficult to harmonize with each other and there was a concern that the space of kitchen or living room would be reduced.

In other words, the best place to install a pulsator type washing machine in the kitchen is to be installed in the sink in harmony with other devices. It is very vulnerable to use with dishwasher or cutting board. This fragile structure is the same even when the pulsator type washing machine is installed in the living room. As a result, as the pulsator type washing machine takes such a weak structure, unbalanced space arrangement with other devices is induced, which may not be aesthetically sound and the space after installation may be narrowed. Accordingly, the pulsator type washing machine is installed and used in an inconspicuous place such as a toilet or a veranda.

On the other hand, the drum type washing machine takes a structure in which the inner tank of the washing tank is placed in a horizontal state with the horizontal structure having a low height, and also takes the front opening and closing type structure in which laundry can be put into the front part. Although it can solve the aesthetics and the inefficiency of space utilization, which is a concern of the pulsator washing machine, the washing capacity is smaller than that of the pulsator type washing machine. As the rotational force is transmitted, excessive vibration such as conical mode vibration is caused, which makes it unsuitable for equipping it in the kitchen sink or living room. Not suitable for

Accordingly, there is a limitation (specificity) of the installation space to be installed and used in the bathroom or the veranda, which can reduce the damage from the vibration and the noise generated by the rotation of the inner tank, which is a washing tank.

Therefore, in general, a washing machine having a larger washing capacity, better washing ability, and less vibration than a drum type washing machine has been required.

In other words, it is required to develop a pulsator type washing machine with a new method to achieve aesthetics, efficiency of space utilization and diversity (non-limiting) of installation space.

By the necessity described above, it is an object of the present invention to provide a washing machine having a drawer function that can take advantage of the installation space efficiently and aesthetically good even after installation and can be pulled out in the lateral direction so that it can be installed in various places.

In addition, another object of the present invention is to secure the connection and fixing of the flow path portion during the withdrawal.
