Description

Detergent case of washing machine

The present invention relates to a detergent case of a washing machine, and more particularly, to a detergent case of a washing machine in which a guide and a spring are installed on the sidewall of the detergent case so that the detergent case is smoothly and elastically drawn out.

In general, detergents, or surfactants, act to change the surface tension of water, fibers, and dirts so that they can fall off the fibers. This detergent removal process specifically involves the penetration of water into the fiber while lowering the surface tension of the detergent, and the detergent molecules having the lipophilic and hydrophilic groups that surround it to loosen the grease. Detergents are removed by emulsification, by dispersing the detergent molecules by wrapping them away from the fibers, preventing them from reattaching to the surface of the fibers, and by subdividing the floating particles in the action of the detergent molecules.

However, it takes a considerable time to remove the time with these detergents alone, so it is necessary to rub the laundry with each other or mechanical strength, such as a washing machine.

In order to prevent the clothing from being damaged, it is better to wash the clothes effectively in a short time, but various conditions such as the degree of dirt of the laundry, the temperature of the washing liquid, the hardness, and the ratio of the washing liquid to the laundry should be appropriate.

Such detergents are generally stored separately from the washing machine, but there is also a washing machine that allows the detergent to be stored inside the washing machine while the detergent is accommodated in the detergent case.

As an example, the conventional detergent case will be described with reference to the accompanying drawings.

As shown in FIG. 1, the conventional detergent case 10 is configured to be inserted into and withdrawn from the case collection 14 formed at the rear of the upper cover 12 of the washing machine.

The washing machine has a washing tank 16 installed therein and a box-shaped outer box covered with an outer box. The upper cover 12 is mounted above the outer box, and the washing tank 16 is disposed on the upper rear end of the upper cover 12. A door 18 for opening and closing the door is provided.

The rear of the upper cover 12 is formed with a case house 14 is concave indented inwardly is inserted into the case house 14 is provided with a detergent case 10 that can be taken out.

The detergent case 10 is open to the upper side and the front of the handle (10a) is formed to accommodate the detergent in a rectangular box shape.

In the prior art of the above configuration, the detergent case 10 is accommodated in the detergent case 10 and then inserted into the case collection 14 of the upper cover 12, and when the detergent is put into the laundry, the detergent case 14 is partially withdrawn. You can get the detergent out.

However, since the detergent case 10 does not have a separate guide device, when the detergent case 10 is inserted and withdrawn, there is a lot of play left and right, and it is also inconvenient to close the detergent case 10. There was a problem such that the detergent (10) was released to the outside and the detergent was poured out.

The present invention has been made to solve the above problems, so that the insertion and withdrawal of the detergent case is soft, and also pull out and release the detergent case at the same time so as not to be released to the outside even if you pull the detergent case quickly It is an object of the present invention to provide a detergent case of a washing machine that can be automatically inserted into the case house by elasticity.

The present invention for achieving the above object is a guide rail formed in the longitudinal direction on both side walls of the detergent case, a guide groove coupled to the guide rail on the side wall of the case house, the case side wall and the case house side wall It is characterized in that the detergent case of the washing machine provided with a spring that is supported by the elastically withdraw the case.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2 to FIG. 4B, the present invention has a case house 24 formed on the top cover 22 of the washing machine, and the spring 26 is elastically drawn out of the case house 24. It is an installed configuration.

The case collection 24 is a shape in which the rectangular space concave inwards in the rear of the upper cover 22 is formed in the first, second guide grooves 24a formed long upward and downward to guide the detergent case 20 on both sides. 24b) is provided, and at the rear of the side wall of the case housing 24 located between the guide grooves 24a and 24b, annular second locking portions 24c into which one end of the spring 26 is fitted are formed on both sides, respectively. have.

The detergent case 20 has a rectangular box shape with an open upper side, and a handle 20a is formed at the front to draw the detergent case 20, and springs 26 are fitted to the second catching portions 24c on both side walls. The first locking portion 20b is formed to be fitted with the other end of the support portion, and a side pulley groove 20c is provided at the side thereof and the support pulley 28 is moved back and forth along the pulley groove 20c. Is installed to support the expansion and contraction of the spring (26). The first and second guide rails 20d and 20e guided along the guide grooves 24a and 24b of the case collection 24 are laterally disposed on both side walls of the detergent case 20. It protrudes sufficiently beyond the thickness of the spring 26.

The second guide rail 20e is cut out by the thickness of the spring 26 at the position where the spring 26 is installed.

The spring 26 has a shape in which three characters form a circle in the center thereof, and both ends thereof are caught by the first and second locking portions 20b and 24c, respectively, and the central portion is in close contact with the lower side of the support pulley 28. It is provided so that the spring 26 may be extended by drawing out the 20.

The support pulley 28 is cylindrically installed to protrude to both sides with the pulley groove 20c interposed therebetween, and moves back and forth along the pulley groove 20c to support the spring 26.

The present invention of such a configuration is that one end of the spring 26 is fitted to the second catching portion 24c formed on both side walls of the case collection 24 and the other end of the spring 26 is formed on the sidewall of the detergent case 20. The spring 26 is installed by fitting the first catching portion 20b and bringing the center portion of the spring 26 into close contact with the lower end portion of the support pulley 28. In this case, the first and second guide rails 20d and 20e of the detergent case 20 are inserted along the first and second guide grooves 24a and 24b of the case collection 24.

After the detergent is accommodated in the detergent case 20 in this state, the detergent case 20 is inserted into the case collection 24, and the handle 20a of the detergent case 20 when the detergent is put into the laundry. Pull out the detergent case 20. Then, as the springs 26 installed on both side walls extend, the detergent case 20 is smoothly drawn out to the outside along the guide grooves 24a and 24b of the side walls by the guide rails 20d and 20e. When the detergent is dispensed as much as used, and then release the handle 20a of the detergent case 20, the spring 26 in the extended state is contracted to its original state, and the detergent case 20 is sucked into the case collection 24.

As described above, the detergent case of the washing machine according to the present invention is not convenient to insert and withdraw because the detergent case does not have any guide facility in the related art, and the detergent case because there is no separate fixing means between the detergent case and the case collection. Unlike the case in which there is a risk of leaving the outside, by providing a guide rail in the detergent case and allowing the detergent case to be withdrawn elastically by a spring, the detergent case is smoothly inserted and withdrawn, and the detergent case is supported by the spring. It is possible to obtain an effect that can prevent the departure to the outside.
