This paper relates to a hot air circulation system of a dry washing machine. More specifically, even when hot air in the washing tank is introduced through the air duct during the operation of the blower according to the drying operation of the dry washing machine, the driving motor side is not reached. The heating member is put into the washing tank again while being heated again to a high temperature via diesel, preventing hot air loss, thereby increasing drying efficiency and shortening the operating time of the heating member and the driving motor, thereby extending the service life. It relates to a circulator.

1 is an overall cross-sectional view for showing the structure of a general dry washing machine, 100 is a main body of the washing machine, 200 is a drive unit for generating power required for the washing machine, 300 and 400 are the drive unit (200) is a stirrer and a washing tank receiving the driving force generated in the forward and reverse rotation, (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.

In the configuration, the driving unit 200 is a motor 201 for generating power, a clutch 203 for regulating the power of the motor 201 transmitted through the pulley 202, and an interruption by the clutch 203. Consists of a power shaft 204 for transmitting the power of the motor 201 to the stirrer 300 or the washing tank 400.

The heating unit 500 of the configuration is provided in the upper rear of the water tank 600 inside the main body 100, the heating member 510 for generating heat by receiving power, and in the lower place adjacent to the heating member 510 It is provided with a thermostat 520 to prevent overheating of the heating member 510, and is provided at the rear of the heating member 510 is driven to receive the driving force of the motor 540 and generates high heat generated by the heating member 510 It is composed of a blower 530 for forced circulation into the water tank (600).

In the drawings, reference numeral 700 denotes a drain valve, and 800 denotes a duct that communicates with the drain valve to evaporate moisture generated when the laundry is dried. Therefore, when the washing machine is operated after putting the laundry into the washing tank 400, 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 is supplied according to the washing amount by manipulation of the water supply side. When the washing water is supplied according to the washing amount, the driving unit 200 rotates the stirrer 300 left and right, and occurs when the stirrer 300 rotates left and right. Washing is performed by the friction of the laundry and wash water and the stirrer 300 and the washing tank 400.

When dewatering, the clutch 203 transmits the power of the motor 201 to the washing tub 400 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 rotates the laundry, and when the heating member 510 is heated, the blower 530 is driven and heats the high heat generated by the heating member 510 to the water tank 600 and the washing chamber. Force circulation

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

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

However, the following problems are pointed out in the general drying, water supply of laundry in a washing machine, and washing administration.

That is, when the washing amount is measured, washing water of cold and hot water according to the washing amount is supplied by the operation of the water supply side. When the washing water is supplied, 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 carried out by the friction of the laundry and the washing water and the stirrer 300 and the washing tank 400 generated during the time, the hot hot air introduced into the washing tank through the first blower 530 as shown by the dashed line in FIG. After the heat exchange with the wet laundry becomes a hot air in the wet state, the wet hot air in the washing tank is not discharged to the outside and is forced to be blown back into the washing tank under the driving of the blower, so the drying is performed under the repeated circulation of the wet hot air, thus eventually heating. The problem is that the heating time of the member is delayed and thus the power consumption increases.

In order to solve such a problem, the present applicant has proposed a utility model registration application 93-7659, which is pending.

In other words, it sucks the high temperature of the humid state and the external cold air in the washing tank at the time of driving the blower at the same time, condensing the moisture by the temperature difference in the area where the high temperature of the humid state and the cold wind intersect, drains the condensed water and the high temperature into the washing tank. By supplying only the dry hot air, the drying efficiency of the laundry is increased to relatively reduce the drying time and power consumption.

However, the problem here is that the blower sucks the air in the air and unilaterally introduces it into the washing tank, so that the hot air in the washing tank is naturally exhausted through the drain valve, so the continuous operation of the heating member due to the loss of hot air and the life of the heating member due to it. Another problem of shortening is pointed out.

It is not limited to this, and the performance of natural exhaust by the drain valve is not remarkable. Therefore, the hot air in the washing tank flows back to the blower motor through the blower duct, resulting in lowering of drying efficiency and shortening of life due to overheating of the motor. .

Therefore, this proposal does not reach the driving motor even when the hot air in the washing tank flows through the blowing duct when the blower is driven, and the hot air is put into the washing tank again by heating the heating element to high temperature again to prevent hot air loss. The purpose of the present invention is to provide a hot air circulation system of a dry washing machine that can increase the drying efficiency and thereby shorten the operating time of the heating member and the driving motor.

The present invention, which achieves the above object, is integrally protruded in communication with one side of the water tank cover inside the washing machine, and an exhaust guide unit for guiding the hot air in the washing tank during the drying administration of the washing machine, and coincides with the center line of the exhaust guide unit. The suction guide part is installed in communication with the lower end of the air blowing duct and suction guides the hot air passing through the exhaust guide part, and is installed inside and outside of the air blowing duct in accordance with the center line of the suction guide part and sucked through the suction guide parts. It is achieved by providing a hot air circulator of a dry washing machine including a hot air guide unit for preventing hot air upward and forcibly blowing air to one side.

Subsequently, preferred embodiments of the present invention which achieve the above object will be described in detail with reference to the accompanying drawings.

FIG. 2 is a cross-sectional configuration diagram of a dry washing machine provided with a hot air circulation system according to the present invention, and FIG. 3 is an enlarged view of portion A of FIG.

As shown in the drawing, on one side of the water tank cover 3 inside the washing machine 1, the exhaust guide unit 30 for guiding the hot air in the washing tank 2 during the drying administration of the washing machine 1 is communicated integrally. It is installed, the suction guide portion for expanding the suction guide to the hot air passing through the exhaust guide portion 30 is installed in the lower side of the upper side of the exhaust guide portion 30 in communication with the center line of the exhaust guide portion (30) A blowing duct 4 having 40 is provided.

Preferably, the diameter of the suction guide portion 40 should be larger than the diameter of the exhaust guide portion 30.

In addition, a heating member 41 is provided inside the blowing duct 4, and the other end thereof is installed in communication with the water tank cover 3 as a flexible connecting pipe 42, which is similar to the conventional configuration.

In this case, however, the flexible connecting pipe 42 provided at one end of the blowing duct 4 should be installed to be located inside the washing tub 2.

In addition, the hot air guide for forcibly blowing hot air passing through the suction guide unit 40 toward the connection pipe 42 at one end of the blower duct 4 in the inner and outer sides of the blower duct 4 so as to match the center line of the suction guide unit 40. Part 5 is installed.

The hot air guide unit 5 is installed on one side of the blower duct 4 to provide a driving force, and a suction fan 51 built up above the drive motor 50 to suck outside air into the inside. ) And a blower configured to be located under the driving motor 50 so as to be positioned inside the blower duct 4 and forcibly blowing hot air introduced into the suction guide unit 40 toward the connecting pipe 42 of the blower duct 4. The fan 52 is comprised.

Preferably the blowing fan 52 is preferably composed of a blower fan. In this configuration configured as described above, when washing → rinsing → drainage → dehydration stroke is completed in sequence by a control program or user setting data, the stirrer rotates intermittently, and when the heating member 41 is heated at the same time as the laundry is rotated, it is driven. The blower fan 52 is driven under the driving of the motor 50, and performs a drying operation similarly to the conventional one, forcibly circulating high heat generated by the heating member 41 to the water tank and the laundry irrigator.

However, the dominant feature of this paper is that when the heating member 41 is heated during the drying stroke, the driving motor 50 is driven and at the same time the suction fan 51 built up above the driving motor 50 rotates to suck in the outside air. In addition, the suction fan 52 formed in the lower side of the driving motor 50 is rotated and the air duct 4 having the exhaust guide part 30 and the blower fan 52 of the water tank cover 3 is rotated. The hot air in the washing tank 2 introduced into the 40 is forcedly blown into the washing tank 2 through the connecting pipe 42 provided at one end of the blowing duct 4 as shown by the arrow in FIG. More specifically, the hot air in the washing tank 2 introduced into the driving motor 50 via the exhaust guide 30 and the suction guide 40 is rotated by the suction fan 51 installed above the driving motor 50. By repeating the circulation into the washing tank (2) through the connecting pipe 42 of the blower duct (4) in the state of being heated to a higher temperature by the heating member 41 by the flow into the drive motor (50). Therefore, in the drying administration of the conventional washing machine, the blower sucks air in the air and unilaterally introduces it into the washing tank. As the hot air in the washing tank is naturally exhausted through the drain valve, the continuous operation of the heating member due to the loss of the hot wind and the heating caused by it The conventional problem which shortened the lifetime of a member, and thereby the fall of drying efficiency and shortened the lifetime by overheating of a motor is actively solved.

As described above, the present proposal does not reach the driving motor even when the hot air in the washing tank is introduced through the air duct during the operation of the blower according to the drying administration of the washing machine, and the hot air is heated to high temperature again via the heating member. As it is put into the washing tank again, it prevents hot air loss, thereby increasing drying efficiency and shortening the heating time of the heating member and the driving motor, thereby extending the service life, thereby improving the reliability of the product.
