The present invention relates to a hot air circulation system of a dry washing machine, and in particular, by sucking the high temperature and high humidity in the washing tank under the driving of the blower during the drying administration of the dry washing machine and forcibly circulating it between the cold water pipes through which the cold water flows. It condenses the condensed water and drains the condensed water in the washing tank by supplying only high-temperature dry hot air to improve the drying efficiency of the laundry, and thus relates to a hot air-cleaning device of a dry washing machine that can reduce the drying time and power consumption.

1 is an overall cross-sectional view for showing the structure of a general dry washing machine, (100) is the main body of the washing machine, (200) is a drive unit for generating the power required for the washing machine, (300) and (400) the ball Receiving the driving force generated in the unit 200 is a stirrer and washing tank that rotates forward and reverse, 500 is a heating unit for heating and drying the laundry finished up to the dehydration stroke, 600 is a predetermined amount of water required for the washing administration It is a tank to be explored.

In the configuration, the driving unit 200 is intermittent by the motor 201 generating power, the clutch 203 intermitting the power of the motor 201 transmitted through the pulley 202, and the clutch 203. It consists of a power side 204 which transmits the power of the motor 201 to the stirrer 300 or the washing tank 400.

The heating unit 500 of the configuration is provided at one side between the water tank 600 and the washing tank 400 and is provided adjacent to the heating member 510 and the heating member 510 to generate heat by applying power. A thermostat 520 for preventing overheating of the member 510, a blower 530 provided at the rear of the heating member 510 to strongly circulate high heat generated by the heating member 150 under driving; The air blowing unit 530 is installed in communication with the lower side and the water tank 600 is composed of a blowing guide 540 for guiding the air in the water tank 600 to the air blowing unit 530.

In the drawing, reference numeral 610 is an overflow pipe which is installed in the washing tank and continues to supply the clean water after the drained water is completely drained, and 700 is a hydrant for supplying the washing water into the tank.

Therefore, when the laundry is put in the washing tank 400 and the washing machine is operated, the motor 201 is operated by the control program or the user's setting data, and the power of the motor 201 is transmitted to the clutch 203 through the pulley 202. do.

The clutch 203 transmits the power of the motor 201 transmitted through the pulley 202 according to washing or dehydration to the stirrer 300 or the washing tank 400 through the power shaft 204.

That is, during washing, the clutch 203 operates so that the power of the driving unit 200 is transmitted to the stirrer 300, and at the initial stage of washing, the driving unit 200 rotates the stirrer 300 from side to side to measure the washing amount.

When the washing amount is measured, the washing water according to the washing amount is supplied through the water supply by the water supply operation. When the other washing water is supplied to the washing amount, the driving unit 200 rotates the stirrer 300 to the left and right and rotates the stirrer 300 to the left and right. Washing is performed by the friction of the laundry and the washing water and the stirrer 300 and the washing tank 400 generated during.

When dehydration, the clutch 203 is transmitted to the power washing tub 400 of the motor 201 to rotate the washing tub 400 at high speed to perform the dehydrating stroke.

Of course, the drainage stroke is performed before the dehydration stroke.

When the dehydration stroke is completed, the stirrer rotates intermittently and at the same time rotates the laundry, and when the heating member 510 is heated, the blower 530 is driven and heats the heat generated by the heating member 510 to the water tank 600 and the laundry irradiator. Force circulation

Therefore, the forced high temperature heat is introduced into the laundry 400 through a plurality of through holes (not shown) provided in the washing tank 400, and the water evaporated when the laundry is heated and dried and heat exchanged in the water tank 600 overflows. It is discharged to the outside through the pipe, the drain valve and the duct.

According to this operation principle, the washing machine repeatedly performs water supply, washing, drainage, rinsing and dehydration drying operation according to a control program or user setting data.

However, the following problems are pointed out when performing the drying administration of laundry in such a conventional dry washing machine.

That is, when drying the laundry after dehydration, the stirrer 300 intermittently rotates the laundry in a wet state in the washing tank 400 intermittently and reversely, and at the same time, blows high heat emitted from the heating member 510. 530 is blown back into the washing tank 400 under forced suction through the blowing guide 540 to the high temperature is repeatedly introduced into the washing tank 400 through the through-hole formed in the washing tank 400 In order to dry the laundry, the air forced to be blown into the water tank through the blower 530 through the blower guide part 540 is in a humid hot air state, thereby reducing the drying efficiency of the laundry.

More specifically, the hot hot air introduced into the washing tank through the first blower 530 as shown in the dashed-dotted line of FIG. 1 becomes a wet hot air state after heat-exchanging with the wet laundry. Because it is not discharged to the air and forcedly blows it back into the washing tank under the driving of the blower, the drying is performed under the repeated circulation of wet hot air, resulting in a long heating time of the heating member, which delays the drying time and increases the power consumption accordingly. It became.

The above-mentioned conventional problems are caused by structural problems if the humid hot air in the washing tank is not discharged to the outside and continuously circulates repeatedly through the air blowing guide and the air blowing unit.

The present invention is conceived in view of the above-mentioned conventional technical shortcomings, and condenses moisture by condensing moisture by the temperature difference while forcibly circulating the hot and humid air in the washing tank during the operation of the blower and forcedly circulating it between the cold water pipes through which the cold water flows. The purpose of the present invention is to provide a hot air circulation system of a dry washing machine which can improve the drying efficiency of laundry and reduce the drying time and power consumption by supplying only high temperature dry hot air into the washing tank.

The present invention to achieve the above object is provided in the upper side of the water tank rear of the washing machine, and having a heating member on the other side and a heating member on the other side and the lower side is in communication with the water tank, respectively, while the drain pipe in communication with the drain valve in place And a condensing means installed in the casing, the condenser means being connected to a water supply valve for supplying the washing water, and condensing and liquefying heat and hot air, which is selectively supplied with the washing water, and sucked by the blower. It is achieved by providing a hot air circulation system of a dry washing machine.

Hereinafter, preferred embodiments of the present invention for achieving the above object will be described in detail by the accompanying drawings.

2 is an embodiment of a dry washing machine equipped with a hot air circulation device according to the present invention.

As shown, it is provided in the upper rear of the water tank 600A in the drying machine, and has a blower 530A in one side and a heating member 520A in the other side, and the lower side thereof is in communication with the water tank 600A, respectively, while the bottom surface is in place. A casing 10 having a drain pipe 10 communicating with the drain valve is installed in the casing 10.

Preferably, the casing is preferably configured to be bent downward toward the drain pipe 10 for smooth drainage of condensed liquefied water.

Condensing means (2) in one end of the casing (1) is in communication with the water supply valve for supplying the wash water is selectively supplied with the wash water to condense and liquefy the hot and humid air sucked by the blower 530A under heat exchange Is provided.

Preferably, the condensation means (2) is preferably installed so that the cold water is supplied through the water supply of the water supply unit.

More preferably, the condensation means (2) is easy to transfer heat and is composed of a metal tube wound in a spiral, and one end thereof is more preferably installed in communication with the drain pipe.

For convenience of explanation, the same parts and members as in the related art are denoted by the same member number with A added.

When the heating member 510A is heated in the drying stroke for drying the laundry in the wet state after the initial water supply, washing, draining, rinsing, and dehydrating in the present invention configured as described above, the blower 530A is driven and the heating member 510A High heat generated by heat is forcedly circulated likewise conventionally between the water tank 600A and the washing tank as shown by the dashed-dotted line in FIG.

However, the dominant feature of the present invention is that the high heat introduced into the washing tank is heat exchanged with the laundry in a humid state, and then becomes high temperature and high humidity air, which is then brought into the casing 1 by the suction force of the blower 530A. The air, which is introduced in a high temperature and humidity by the blowing guide part 530A, is condensed and liquefied downward by a temperature difference with the condensing means 2 in which washing water of cold water is supplied by a small amount to the inside by operation of the tap water. It is drained to the drain valve through the drain pipe 10 along the bottom surface of the casing (1).

More specifically, the hot and humid air in the water tank 600A introduced into the casing 1 by the suction force of the blower member 530A is moved to the heating member 510A side as shown by the dashed line in FIG. The hot and humid air is condensed by the relative temperature difference when condensing means (2) consisting of a metal tube in which the washing water of cold water is supplied by a small amount of water to the inside by operation of the tap water. Since the water is drained to the outside through the drain pipe 10 and the drain valve along the downwardly inclined slope of), substantially the air flowing into the washing tank 4000A becomes the hot and dry air, and the washing water flowing into the condensation means 2 is The drain pipe 10 communicated with one end is drained by a diesel drain valve.

Therefore, when the blower 530A is driven, the hot and humid air in the washing tank 400 cannot be discharged to the outside as in the prior art, and is continuously circulated by the blower 530, thereby heating the heating member 510 derived therefrom. The conventional problem of delay in time and drying administration time and thus increase in power consumption is actively solved.

As described above, the present invention inhales the high temperature and high humidity air in the washing tank under the driving of the blower during the drying operation of the dry washing machine and forcibly circulates it between the cold water pipes through which the cold water flows. By draining and supplying only high temperature dry hot air into the washing tank, the drying efficiency of the laundry can be improved, and the drying time and power consumption can be reduced, thereby improving the reliability of the product.
