This invention has the process of drying a laundry by blowing a warm air in an inner tank, and relates to the laundry dryer which can carry out from washing to drying collectively.

Conventionally, this kind of laundry dryer is comprised as shown in FIG. The configuration will be described below.

As shown in FIG. 8, the main body 1 hangs the outer jaw 2 by the suspension mechanism 3, and prevents and supports the vibration. The motor 4 is provided below the outer jaw 2. The motor 4 is provided with an external jaw through a washing / dehydration shaft 5 having a two-axis hollow structure and a clutch 6 for switching the transmission of rotational force to the washing and dehydration shaft 5 during washing or dehydration. The inside of 2) is connected to the inner jaw 7 rotatably provided with the rotation center axis in a perpendicular direction.

A fluid balancer 8 is provided above the inner jaw 7. The rotary blade 9 is rotatably attached to the inner bottom of the inner jaw 7. The drain valve 10 drains the water in the outer tank 2. The drying blower 11 which blows warm air in the inner tank 7 is installed in the substantially lower part of the main body 1. The blower 11 is comprised so that the warm air heated by the heater 13 through the heat exchange part 12 may blow warm air in the inner tank 7. The heat exchange part 12 is provided with a water supply part 14 for dehumidifying by water cooling.

The upper surface of the outer jaw 2 is covered by the outer jaw cover 15, and an inner cover 16 that can be opened and closed is provided at a substantially central portion of the outer jaw cover 15. Between the main body 1 and the outer jaw cover 15, a stretchable upper corrugated hose 18 communicating with the air passage 17 is provided in the substantially vertical direction. The lower part of the outer tank 2 and the drying blower 11 are connected with the lower crimping hose 19. As shown in FIG. Into the inner jaw (7) is put clothing.

The circulating air by the drying blower 11 passes through the heat exchange part 12 and the heater 13 from the air passage 17 to the upper corrugated hose 18, inside the inner jaw 7, and around the inner jaw 7. Through a small hole (not shown), a lower portion of the outer jaw 2, and a lower corrugated hose 19 installed at the lower portion of the outer jaw 2, the water is circulated to the drying blower 11 again.

The operation of the above conventional example will be described below. First, the washing process will be described. Clothing and detergent are put into the inner tank 7 and cold or hot water is supplied to a predetermined level. The clutch 6 of the transmission mechanism portion transmits the power of the motor 4 to the rotary blade 9 via the washing and dewatering shaft 5 to rotate the rotary blade 9. As a result, the garment is stirred and washed in water.

When the washing process is completed, the drain valve 10 is opened to drain the water in the inner tank 7, and water is supplied again to drive the rotary blade 9 to rinse.

After completion of the rinsing step, in the dewatering step, the water in the inner tank 7 is drained by opening the drain valve 10. Thereafter, the clutch 6 of the transmission mechanism portion is switched to the dehydration side, the power of the motor 4 is transmitted to the inner tub 7 via the washing and dehydration shaft 5, and rotated to apply centrifugal force to the clothes. As a result, water is separated from the clothes and passed through the drain valve 10 to the outside.

In the drying step, the rotary blade 9 is slowly rotated first to remove the clothing attached to the inner wall of the inner jaw 7 by centrifugal force during dehydration. Thereafter, the rotary blade 9 is instantaneously rotated strongly in the direction of normal and reverse, and the clothes are unwound upward in the inner jaw 7 and stirred.

At the same time, the warm air heated by passing the heater 13 by the drying blower 11 is sent to the inside of the inner tank 7 via the upper corrugated hose 18. This warm air warms the clothes in the inner tank 7 to evaporate its moisture, and is cooled by the water supplied from the water supply unit 14 when passing through the heat exchange unit 12. As a result, the warm air is dehumidified, and the dehumidified water is drained from the dehumidification drain 20.

In the conventional laundry dryer, when the water supply valve (not shown) supplied in the inner tank 7 breaks down and the water supply continues, the water level in the inner tank 7 is increased to reach the outer tank cover 15. In addition, when the water level rises, it enters the upper corrugated hose 18.

On the other hand, although the heater 13 is provided in the upper part of the heat exchange part 12 is shown, it is not specified about the mounting position, and it is feared that it is submerged by the water which entered the upper corrugation hose 18. If submerged in water, there is a possibility of carrying a risk of a safety problem such as a decrease in insulation resistance.

In this solution, the heater 13 is provided in the air passage 17 at the upper part of the main body 1, disposed in the upper part of the main body 1, and is not shown, but the air passage 17 is covered with the panel. In the case of the configuration, when the water supply valve for supplying water in the inner tank 7 is disposed in the panel, the water supply valve has a problem that needs to be solved in configuration because the external shape of the water supply valve is smaller than that of the air passage 17 incorporating the heater 13. .

(Example 1)

As shown in FIG. 1, the main body 21 hangs the outer jaw 22 by the suspension mechanism 23, and prevents and supports the vibration. The motor 24 is provided below the outer jaw 22. The motor 24 has an outer jaw (via a two-axis hollow washing / dehydration shaft 25 and a clutch 26 for switching the transmission of rotational force to the washing and dehydration shaft 25 when washing or dewatering). It is connected to the inner jaw 27 rotatably installed in 22 inside. The central axis of rotation of the inner jaw 27 is vertical.

A fluid balancer 28 is provided above the inner jaw 27. The rotary blade 29 is rotatably attached to the inner bottom of the inner jaw 27. The rotary blade 29 is formed in a substantially pot shape having an inclined surface which becomes high in the circumferential direction.

The drying blower (blowing means) 30 blows warm air into the inner tank 27 for drying. The blower 30 is configured to blow the warm air heated by the heater (heating means) 31 into the inner tank 27. The blowing path 32 which guides the blowing by the drying blower 30, the heater 31, and the drying blower 30 into the inner tank 27 comprises the hot air blower 33. As shown in FIG. Here, the blowing path 32 is formed in an inverted U shape. The heater 31 is arrange | positioned in the upper flat part 32a of the ventilation path 32. As shown in FIG. In addition, as shown in FIG. 2, the ventilation path 32 has the inclined surface 32b inclined gently from the lowest surface in the upper flat part 32a formed in reverse U shape.

One end of the heat exchange part 34 is connected to the bottom of the outer tank 22 via the connecting duct 35, and the other end thereof is connected to the hot air blower 33. In the drying process, the heat exchange part 34 cools and dehumidifies the hot air of high humidity passing through the inside by air cooling or water cooling.

The upper surface of the outer jaw 22 is covered by an outer jaw cover 36 fixed to the outer jaw 22. The outer jaw cover 36 is sealed with the outer jaw 22 by a sealing material, an adhesive (not shown), or the like. As a result, the warm air is prevented from escaping to the atmosphere. In addition, although not shown, the outer jaw cover 36 is provided with a clothes inlet for entering and leaving the clothes, and an inner cover for closing the clothes inlet is provided to be opened and closed.

In addition, the outer jaw cover 36 is provided with a hot air blowing port 37 and a water supply port 38. The hot air blower 37 is connected to the air blower path 32 through the flexible corrugated hose 39, and the water supply port 38 is connected to the water supply member 41 through the flexible corrugated hose 40. As a result, the corrugated hoses 39 and 40 expand and contract even when the outer tub 22 vibrates in the washing step, the dewatering step, and the like, so that the water supply member 41 and the hot air blower 33 and the hot air blower 37 are separated. Watertightness is maintained between the water inlets 38.

The water supply member 41 is provided with a detergent dispenser 42 so as to be withdrawn. Water supplied from the water supply valve (water supply means) 43 to the detergent inlet 42 through the water supply duct 44 dissolves the detergent introduced into the detergent inlet 42. The water in which the detergent is dissolved is supplied from the water supply port 38 into the inner tank 27 through the pleated hose 40. Here, the water supply member 41 is disposed in a space below the blowing path 32 formed in an inverted U shape, that is, below the heater 31.

The check valve 45 provided at the tip of the water supply port 38 is configured to open with water pressure from the water supply valve 43 and close when the water pressure disappears. And the check valve 45 is formed of a flexible member in order to close the water supply port 38 securely. The drain valve 46 discharges the water in the inner tank 27 out of the machine. The drainage path 47 is formed on the side of the outer jaw 22 by discharging water stored in the upper portion of the outer jaw cover 36 out of the machine in the event of an abnormality.

The lower panel 48 is mounted on the upper portion of the main body 21. The upper surface of the lower panel 48 is covered by the upper panel 49. The above-mentioned hot air blower 33, the water supply valve 43, and the like are disposed in the panel space 50 surrounded by the lower panel 48 and the upper panel 49. The hose connecting portion 43a of the water supply valve 43 is projected on the upper surface of the upper panel 49 so as to connect a water supply hose (not shown) from the outside.

The operation in the above configuration will be described. Detergent inlet portion which is connected to the water supply hose connected to the faucet to the hose connecting portion 43a of the water supply valve 43, injects clothing and detergent into the inner tank 27, and is provided to be pulled out of the water supply member 41 ( 42) Add detergent to start operation. In the washing process, the water supply valve 43 is opened to supply tap water to the water supply member 41. The tap water is internally supplied from the water supply port 38 via the pleated hose 40 while dissolving the detergent in the detergent inlet 42. Water is supplied into the tank 27. At this time, the check valve 45 is opened by the water supply water pressure.

When water is supplied to a predetermined level, the power of the motor 24 is transmitted to the rotary blade 29 through the washing and dehydration shaft 25 by the clutch 26 of the transmission mechanism part. As the rotary blade 29 rotates, the garment is agitated and washed in water. When the washing process is completed, the drain valve 46 is opened, the water in the inner tank 27 is drained, water is supplied again, and the rotary blade 29 is driven to rinse.

In the dehydration step, after the rinsing step is completed, the drain valve 46 in the inner tank 27 is opened and drained, and then the clutch 26 of the transmission mechanism part is switched to the dehydration side, and the power of the motor 24 is washed and dehydrated. By transmitting to centrifugal force to the clothes by rotating and transmitting to the inner tank 27 through 25), the water is separated from the clothes and passed through the drain valve 46 to the outside.

In the drying process, the rotary blade 29 is slowly rotated first to remove the clothing attached to the inner wall of the inner tank 27 by centrifugal force during dehydration. Thereafter, the rotary blade 29 is instantaneously rotated strongly in the direction of forward and reverse to unwind the garment upwards in the inner jaw 27 and stir.

At the same time, the warm air heated by passing the heater 31 by the drying blower 30 is sent from the warm air blower 37 into the inner tank 27 via the corrugated hose 39. At this time, since the check valve 45 is closed, the warm air does not escape from the water supply member 41 into the atmosphere.

The warm air sent from the hot air blower opening 37 into the inner tank 27 warms the clothes in the inner tank 27 to evaporate its moisture, and then comes out between the inner tank 27 and the outer tank 22 to form the outer tank ( The path back to the warm air blower 33 is circulated through the connection duct 35 from the bottom of 22 through the heat exchange part 34. The warm air is dehumidified because it is cooled when passing through the heat exchange part 34. Water condensed at that time is drained from the drain valve 46.

In addition, the water condensed on the inner wall surface of the hot air blower 33 is not stored around the heater 31, and the inner tank (from the hot air blower 37 is formed along the inclined surface 32b formed on the air blower path 32). 27) flow into. Therefore, as the dew condensation water is stored, the insulation resistance does not decrease, and safety can be ensured.

Next, the operation in the case where the water supply valve 43 is broken and water supply is continued into the inner tank 27 will be described. In this case, the check valve 45 is opened by water supply water pressure. Water supply continues in the inner tank 27, and the water level in the inner tank 27 is increased, and the water level reaches the water supply port 38. Here, the outer jaw cover 36 forming the water supply port 38 seals with the outer jaw 22. Therefore, since the warm air is prevented from escaping to the atmosphere, the water which has risen above the water supply port 38 penetrates to the water supply member 41 as indicated by the arrow in FIG. 3.

At this time, the water penetrates into the hot air blower 37 as shown by the arrow in FIG. 3 and also penetrates through the heat exchanger 34 from the bottom of the outer tank 22.

As shown in FIG. 3, the water filled up to the water level P overflows water from the gap between the water supply member 41 and the detergent inlet 42, and the overflowed water falls on the upper surface of the outer tank cover 36 so that the outer tank 22 It is discharged to the outside of the machine from the drainage path 47 formed on the side surface. At this time, since the heater 31 is above the water supply member 41, the water does not rise to the position of the heater 31, and the heater 31 is not submerged in the water. Therefore, the insulation resistance of the heater 31 does not fall, and safety can be ensured.

Moreover, since the heater 31 is arrange | positioned in the upper flat part 32a of the ventilation path 32, and the water supply member 41 is arrange | positioned in the space below the heater 31, the heater 31 is reliable. It may be disposed at a position higher than the water supply member 41. Moreover, the heater 31 can be arrange | positioned on the upper part of the water supply member 41, and the water supply member 41 and the heater 31 can be arrange | positioned in order to save space.

In addition, since the blowing path is inclined downward from the lowermost part in the upper flat portion formed in an inverted U shape and is connected to the hot air blowing hole facing the inner tank, the hot air is cooled and generated by touching the inner wall surface of the blowing path. The condensation water to be discharged is not stored in the upper flat portion formed in the inverted U shape, but flows through the inclined surface and is discharged into the inner tank from the hot air jet port. Therefore, as the dew condensation water is stored, the insulation resistance does not decrease, and safety can be ensured.
