Description

Pulsator type washing machine using convection and radiation

The present invention relates to a pulsator type washing machine, and more particularly, to a pulsator type washing machine capable of drying laundry by convection and radiation.

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, a drum type washing machine, and an agitator type washing machine according to a method of applying energy to laundry. That is, the laundry is impacted by a pulsator or agitator, or the laundry is dropped by dropping the laundry by the rotation of the drum to wash the laundry. And the action of the detergent is added to this is done washing.

The above-mentioned washing machines generally have only a function of washing laundry such as clothes. Therefore, the user of the washing machine should take out the laundry from the washing machine after the washing is completed and dry it in the sun.

In recent years, it has been required to be able to artificially dry laundry which has been widely washed in the apartments in a short time due to the widespread use of apartments and changes in living patterns, and a dryer has been developed in response to this demand. The development of a dryer makes it possible to dry laundry which has been washed in a washing machine simply and quickly.

However, in general, a dryer is almost the same size as a washing machine, and therefore, it takes up a lot of space to install each of the washing machine and the dryer, and it is inconvenient to use the laundry having to be removed from the washing machine and put back into the dryer.

Therefore, the development of a washing machine having a drying function has been required. Accordingly, in the drum type washing machine, a washing machine having a drying function capable of being dried directly from a drum without moving laundry after completion of washing has been proposed. In general, however, the washing machine of the pulsator type or agitator type washing machine having a better washing capacity than the drum type has no drying function.

Therefore, there has been a demand for the development of a pulsator type washing machine having good washing ability and capable of drying laundry.

In order to solve the above problems, it is an object of the present invention to provide a pulsator type dry washing machine capable of drying laundry with good washing function.

In order to achieve the above object, the present invention is one end is connected to the lower portion of the outer tank, the other end and the circulation duct located near the upper portion of the inner tank; A blowing fan installed at a predetermined position of the circulation duct and forcibly circulating air; A reflection plate coupled to the tip of the circulation duct; It is installed on the reflector, and provides a pulsator type dry washing machine including an auxiliary heater for heating the air discharged from the circulation duct and generating radiant heat.

According to another embodiment of the present invention, a heater is further provided in the circulation duct.

In addition, it is preferable that a radiation coating layer is formed on the inner wall of the inner tank.

Therefore, according to the present invention, it becomes possible to wash laundry with excellent washing efficiency and to dry it directly in the washing machine without moving the laundry.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the pulsator type dry washing machine according to the present invention will be described.

Referring to Figure 1, when describing the pulsator type dry washing machine according to the present invention.

First, the components for the washing function for washing laundry will be described as follows.

An inner tub 3 for storing the washing water is installed in the washing machine case 1, and an inner tub 5 in which a plurality of through holes 5a are formed is rotatably installed in the tub 3. The pulsator 7 is rotatably installed in the inside of (5). And the inner tank 5 and the pulsator 7 are rotated by the drive means 9 provided in the bottom face of the outer tank 3.

On the other hand, the upper part of the case 1 is provided with a water supply valve 10 for supplying water for washing and rinsing, the water supply valve 10 is a water supply duct (not shown) for supplying water to the inner tank (5) Connected. A drain duct 11 for discharging the dirty laundry water after the completion of washing to the outside of the washing machine is connected to the bottom of the outer tub 3, and a drain valve 13 is installed at a predetermined position of the drain duct 11. .

Next, the components for drying the laundry will be described.

Between the outer tub 3 and the case 1, a circulation duct 20 for supplying heated air for drying the laundry to the inner tub 5 is installed. That is, the lower end of the circulation duct 20 is connected to the lower end of the outer tank 3, the upper end is located near the upper portion of the inner tank (5).

Of course, a predetermined position of the circulation duct 20 is provided with a heater 15 for heating the air and a blowing fan 22 for forcibly circulating the air. Here, it is preferable that the heater 15 is provided in front of the blowing fan 22 (the discharge port direction of the circulation duct).

On the other hand, the air discharged from the discharge port of the circulation duct 20 to dry the clothes in the inner tank 5 and discharged again to the circulation duct 20 is in a humid state. Therefore, when the air in such a humid state is circulated as it is, the drying efficiency is lowered. Therefore, the moisture contained in the air must be removed during the air circulation. That is, the heater 15 performs some dehumidification functions, but it is of course possible to install a separate dehumidification device.

Meanwhile, a reflecting plate 26 is installed at the front end of the circulation duct 20 by penetrating the outer tub cover 50, and an auxiliary heater 15a is installed at the upper portion of the reflecting plate 26. The reason for this configuration is that the air discharged from the tip of the circulation duct 20 is further heated by the auxiliary heater 15a to be supplied to the inner tank 5 and radiant heat generated from the auxiliary heater 15a by using the reflector 26. This is because it can be multiplied by the inner circle (5). Therefore, the laundry in the inner tank 5 is dried by convection and radiant heat of the heating air, so that the laundry is dried in a short time.

On the other hand, it is preferable that the radiation coating layer (5a) is formed on the inner wall of the inner tank 5 in order to more effectively use the radiant heat. The coating layer (5a) can be used as long as it is a material that can effectively reflect without absorbing radiant heat. For example, a material of the same material as the reflective plate 26 may be coated.

Meanwhile, although the heater 15 is installed in the circulation duct 20 and the auxiliary heater 15a is installed in the reflecting plate 26 in the above-described embodiment, the present invention is not limited thereto. That is, if the amount of heat generated by the auxiliary heater 15a installed in the reflector 26 is properly adjusted, the circulation duct 20 may not be provided with the heater 15, but only the auxiliary heater 15a installed in the reflector 26 may be used. Heating and radiant heat can be generated at the same time.

Referring to the operation of the pulsator type dry washing machine according to the present invention described above is as follows.

First, the washing function will be described as follows. The washing function is substantially the same as the operation of a conventional washing machine. That is, the washing stroke, the rinsing stroke and the dehydrating stroke are sequentially performed to wash the laundry.

The drying process begins when washing and dehydration are complete. When the drying process is started, the blowing fan 22 is operated so that the air inside the inner tank 5 circulates through the circulation duct 20 and is supplied to the inner tank 5 again. At this time, the air is heated by the heater 15 is supplied to the inner tank (5). The heated air supplied to the inner tank 5 exchanges heat with the laundry to dry the laundry.

That is, the heated air circulates the inner tank 5 to dry the laundry in the inner tank 5, and the drying process is completed after a predetermined time cycle.

Meanwhile, in the present invention, the laundry is dried not only by the air heated by the heater 15 but also by the radiant heat generated from the auxiliary heater 15a, so that the laundry is dried more effectively.

In the above, the present invention has been described in only one embodiment, but as can be seen in the appended claims, those skilled in the art can make modifications without departing from the spirit of the present invention. It will be understood that it belongs to the scope of the invention.

Referring to the effect of the pulsator type dry washing machine according to the present invention described above are as follows.

First, in the present invention, washing the laundry in a pulsator method is good washing efficiency, and at the same time there is an advantage that the convenience of the user can be improved since the laundry after washing can be immediately dried in the inner tank.

Second, according to the present invention, the laundry in the inner tank is dried by the convection and radiant heat of the heating air has the advantage that the laundry can be dried more efficiently and quickly.
