It is an object of the present invention to provide a top-fed type drum type laundry dryer equipped with a stationary drying course using the technique of such a clothes dryer.

However, the clothes dryer is a so-called front loading type clothes dryer in which the front of the drum is opened, and the clothes dryer is fixed by using the rear end face and the front opening of the drum. Therefore, if the structure is to fix the auxiliary tool on the drum end face side, it is difficult to fix the auxiliary tool to the end face side. For example, in the case where the assisting tool is inserted into the cross section, if the assisting tool is too large, it is impossible to fill the stroke necessary for inserting the assisting tool from the upper side into the cross-section side. Can't.

An object of the present invention is to solve such a problem, and an object of the present invention is to make it possible to easily install a drying aid in a top-fed type drum type laundry dryer.

The drum type laundry dryer of the present invention, as described in claim 1, has a laundry inlet on the upper side of the basket, the outer tub disposed in the basket, and a rotation axis extending in the transverse direction into the interior of the outer tub so as to be freely rotated.

And a drying aid provided in the drum when the stop drying course is to be supplied, and for maintaining laundry in a state having a space between the drum bottom circumferential surfaces. And a shelf member on which laundry is placed, and a leg member extending downward from the shelf member and supporting the shelf member between the drum bottom main surface.

In addition, as in the invention described in claim 2, the drum is provided at a plurality of locations on the main surface of the drum, and has a baffle for lifting laundry, and the drying aid has a leg member to stop the drum in the stop drying course. As the position is determined by a baffle located near the bottom of the drum at this time, it is preferable that the shelf member is installed in a horizontal state.

In addition, as in the invention described in claim 3, the apparatus is provided with a detection device for detecting that the drying aid is installed in the drum, and the control unit is configured to perform the rotation when the drum other than the stop drying course is rotated. When it is detected by the detecting device that the drying aid is provided, it is preferable to stop the driving course and to set the drive motor to the stopped state.

In addition, as in the invention described in claim 4, it is preferable that the control unit is configured to operate the drying apparatus so as to lower the warm air temperature when the laundry dries during the stop drying course.

In the configuration of claim 1 of the present invention, the laundry is supported by the drying aid in a state having a space between the drum bottom circumferential surfaces, so that warm air can be supplied to the upper and lower surfaces of the laundry, The warm air can be passed through and the laundry can be dried without staining.

Further, the drying aid may be simply put into the drum at the laundry inlet, and the leg member may be placed on the drum bottom circumferential surface, and it can be easily installed in the drum.

That is, the hot air outlet into the drum is provided at the center of the cross section in one direction of the drum, and the exhaust port is installed at the center of the cross section in the other direction of the drum, and the warm air from the outlet is supplied to the upper and lower surfaces of the laundry ( It is preferable to be able to dry the laundry effectively by passing through the inside of the laundry and coming out through the air vent or the water passage hole of the drum main surface.

However, the drying aid is not preferable because the laundry member may slide or fall to one side if the shelf member on which the laundry is placed in the drum is not substantially level. However, in the drum laundry dryer, since the drying aid in the drum is viewed from above, the horizontal state of the shelf member is difficult to know, and there is a fear that the drying aid cannot be installed well.

In view of the above, in the second aspect, the drying aid is provided by placing the leg member of the drying aid on the drum bottom circumferential surface such that the leg member of the drying aid is in contact with, for example, the baffle side surface (the surface along the rotation axis direction). At this time, the shelf member is almost horizontal. According to the configuration as described above, the drying aid can be installed in a state where the shelf member is horizontal even by simply placing the leg member in a position determined by the buff, so that the drying aid can be easily installed in an appropriate state. Can be.

In addition, there is no need to provide a dedicated positioning member in the drum in order to position the drying aid, and there is no fear of damaging the laundry such that the positioning member is caught in the laundry during washing or drying.

In addition, in the case where the leg member of the drying aid is placed on the drum bottom circumferential surface and installed in the drum, when the user accidentally runs the drum or the driving course with the drying aid installed, the drying aid Is mixed inside the drum, and the drum or drying aid may be damaged.

In this regard, in the third aspect, when the driving course for rotating the drum is executed, if the detection aid is left in the installed state by the detection device, the operation is stopped and the drum is stopped. Therefore, it is possible to prevent the drying aids from being mixed inside the drum, thereby preventing damage to the drums and the drying aids.

Moreover, some garments which cannot be tumbled dry may cause felt shrinkage and severe shrinkage when the warm air temperature is relatively high while drying to some extent.

In the configuration of claim 4, the drying apparatus is controlled so that the warm air temperature is lowered when the laundry is dried in the stop drying course. Thus, felt shrinkage can be prevented from occurring.

Inside the photoreceptor 1, the outer tank 10 in which the main surface is substantially cylindrical shape and the both end surfaces are occluded is arrange | positioned. The outer tub 10 is supported by two dampers 9 provided at its lower part in the front-rear direction, and the upper part thereof is supported by a plurality of springs (not shown). It is supported freely. Inside the outer tub 10, a horizontal drum 12 in which both end faces of a substantially cylindrical main surface on which a plurality of water passages 12a are drilled is almost colored as an inner tub for accommodating laundry therein. Rotation is provided freely about the horizontal axis C (rotational shaft) which extends. The drum 12 is made of stainless steel, for example.

The main shaft 13 fixed to the center of the left end face of the drum is supported by the bearing 15 held by the 1st bearing (shaft support) case 14 fixed to the left end face of the outer tub 10. On the other hand, the auxiliary shaft 16 fixed to the center of the right end surface of the drum 12 is supported by the second bearing 18 held by the second bearing case 17 fixed to the right end surface of the outer tub 10. It is. The horizontal axis C is formed by the main axis 13 and the auxiliary axis 16. At the tip of the main shaft 13 which protrudes laterally from the left end surface of the outer tub 10, the rotor 19 'of the outer rotor type motor 19 (corresponding to the original drive motor of the present invention) is fixed, and the motor support is The stator 19a of the motor 19 is fixed to the first shaft bearing case 14 which also serves. When a driving current is supplied to the stator 19a from a control circuit (not shown), the rotor 19k is rotated accordingly, and the drum 12 is rotationally driven at the same rotational speed as the rotor 19k via the main shaft 13. .

An outer tub opening 20 for entering and exiting laundry is provided at a position coinciding with the outer laundry inlet 3 from the upper surface inclined from the upper surface of the main surface of the outer tub 10, and the outer tub opening 20 is an outer tub door 21. Opening and closing is free. Moreover, the baffles 24 are provided in three places on the inner circumferential surface of the drum 12 for allowing laundry to enter and exit the main surface of the drum 12 at intervals of about 120 degrees. These buffles 24 are for lifting up laundry by the rotation of the drum 12, and are formed in a long mountain shape in the left-right direction (rotation axis direction). Two of the three baffles 24 are located near the drum opening 22 on both sides of the drum opening 22, and one buff 24 is located opposite the drum opening 22.

In order to make the drum 12 rotatable, there is a drum position fixing device below the stator 19a so that the drum 12 remains stationary at a position where the drum opening 22 coincides with the outer opening 20 in the radial direction. 25) (corresponding to the drum locking device of the present invention for locking the drum) is provided. When the drum 12 is stopped, the engagement convex portion projecting from the drum position fixing device 25 and the engagement recess formed in the rotor 19 'are engaged, and the stop position of the drum 12 is determined. At this time, the baffle 24 facing the drum opening 22 is located near the bottom of the drum 12, specifically, about 30 degrees back from the bottommost position of the drum 12.

Further, a drain port 26 is provided at the bottom of the outer tub 10, and the drain port 26 is connected to an external drain groove through a drain hose not shown through a drain valve 27.

In this way, during the rinsing of the laundry, the drum 12 is reversely rotated at a low speed, and the laundry is lifted and dropped by the baffle 24 to wash or rinse the laundry. At the time of dehydration, as the drum 12 is rotated at a high speed, detergent and water in the laundry are removed.

On the right outer side of the outer tub 10, hot air is supplied into the drum 12 at the time of drying, condensation and liquefaction of vapors taken from the laundry are removed, and then the air is heated again (the drying apparatus of the present invention). Corresponding to) is formed.

Referring to the configuration of the circulation air flow path in detail, the body member 10a constituting the outer tub 10 is an integrally molded product of a synthetic resin, the left end surface of which is almost occluded, the right end surface of which is generally open, and is generally centered in the horizontal axis C direction. The tubular conduit 30 which has the opening 29 which communicates inside the outer tub 10 in the lower part, and extends in the horizontal axis C direction from the said opening 29 to the right end surface is integrally formed. The opening 29 is an air outlet from the outer tub 10 and the conduit 30 is part of the air passage.

A cross-sectional member (10) is almost attached to the right open end surface of the body member (10a) of the outer tub (10), but a cylindrical opening (31) is provided at a portion corresponding to the pipe (30). ) Is installed, and a heat exchanger cover 32 is mounted to cover the opening 31. The inside of the heat exchanger cover 32 is a part of the air flow path, which is a rear longitudinal passage 33 extending almost immediately along the right end surface of the outer tub 10. A water pipe through which a cooling water connected to a dehumidifying water supply valve (not shown), which is not shown, is connected to the upper water pipe connecting portion 32a of the heat exchanger cover 32, and a rear end cylinder is opened from this water pipe. By the water supplied into the furnace 33, the interior functions substantially as a heat exchanger 34.

The posterior longitudinal passage 33 is connected to the posterior transverse passage 35 extending horizontally or slightly inclined upward from the rear upper portion of the outer tub 10, and the posterior transverse passage 35 is connected to the brooder chamber 36. It is connected to the rear. The brower chamber 36 has a built-in brower fan (not shown) which is driven by a brower motor (not shown). The blower chamber 36, the blower fan, and the blower motor constitute a blower. In the right-hand direction of the brooder chamber 36, the horizontal ventilation path 37 extended | stretched substantially horizontally, bent toward the outer side of the cross section of the outer tub 10, and further bent upwards is connected. The end of the horizontal passage 37 is provided so that the opening 17a formed in the second bearing case 17 may be covered. In the transverse passage 37, heaters 38 made of sheath lines are provided side by side in two transverse directions, and this portion becomes a heating device that substantially heats air. A plurality of openings 10c are provided in the outer tub 10 inside the second bearing case 17, and the openings 10c serve as hot air supply holes into the outer tub 10.

In the above configuration, when the blower fan is rotationally driven by the blower motor, the blower fan discharges the air sucked from the rear side toward the side. Therefore, the air flow from the brower chamber 36 toward the transverse passage 37 is formed, and the air heated by the heater 38 while passing through the transverse passage 37 is hot air of the outer tub 10. It feeds into the outer tub 10 through the supply port 10c. The cross section on the side of the auxiliary shaft of the drum 12 has a plurality of openings 16a which are ejection openings around the auxiliary shaft 16, and heating air flows into the drum 12 mainly from the openings 16a. . When the wet laundry is accommodated in the drum 12, the heat-heated air passes through the gaps between the laundry or the fiber gap of the laundry, and then takes moisture from the laundry. The end face of the main shaft side with respect to the drum 12 has a plurality of exhaust holes 12 'that are discharge ports around the spindle 13, and air containing moisture is mainly supplied through the exhaust holes 12 or the water passages 23a. Exit out of 12 and through the gap between the drum 12 and the outer tub 10 to the air outlet 29. This flow of air in the circumferential direction is also accelerated as the drum 12 rotates. Thus, since air of temperature flows surrounding the drum 12 from the surroundings, the drum 12 is maintained at high temperature and high drying efficiency can be achieved.

The air containing a large amount of water vapor taken out from the air outlet 29 to the outside of the outer tub 10 passes through the conduit 30 and the rear end passage 33 to the heat exchanger 34 and is rapidly cooled. As a result, water vapor contained in the air condenses to become water. Accordingly, the air passing through the heat exchanger 34 becomes dry air, passes through the rear transverse passage 35, returns to the brower chamber 36, and circulates to be heated by the heater 38 again. The water condensed in the heat exchanger 34 flows down the inner wall of the heat exchanger cover 32 and is discharged from the drain hole not shown together with the water generated by the condensation.

By the way, when performing the above-mentioned stop drying process, as shown in FIG. 5, the drying aid 40 is provided in the drum 12. As shown in FIG. 7 is a front view of the drying aid, FIG. 8 is a plan view of the drying aid, and FIG. 9 is a side view of the drying aid. The detailed structure of the drying assist tool 40 is demonstrated based on FIG.

The drying aid 40 is made by processing a steel wire rod chromium-plated to prevent rust, and extends downwardly from the shelf member 41 and the shelf member 41 for placing laundry. It consists of the leg member 42 which supports the shelf member 41 between bottom main surfaces.

The shelf member 41 combines the both ends of each of the eight wire rods arranged in parallel with each other at predetermined intervals with the wire rods orthogonal to them. The left and right sides of the shelf member 41 are coupled to the wire rod end of the frontmost row and the wire rod end of the rearmost row constituting the shelf member 41, and stand at a predetermined angle, for example, about 30 degrees from the horizontal direction. The guide 43 which consists of a substantially inverted-shaped wire rod is provided. The shelf member 42 is installed in four places of front, rear, left and right. The left and right shelf members 42 on the front side are made of substantially U-shaped wire rods whose ends are joined to the wire rod end of the second row and the wire rod end of the fourth row, which constitute the shelf member 41, and the rear left and right legs. The member 42 consists of a substantially U-shaped wire rod whose both ends are coupled to the wire rod end of the fifth row and the wire rod end of the seventh row, which constitute the shelf member 41.

The height H of the leg member 42 of the drying aid 40 is as shown in FIG. In the state provided in the drum 12, the position of the shelf member 41 is the height which becomes about half of the center of the drum 12. As shown in FIG. In addition, the depth D of the shelf member 41 is much smaller than the width inside the drum 12. Furthermore, in the state where the leg member 42 placed inside the drum abuts against the base of the side surface 24a (the surface along the horizontal axis) of the drum inner side of the baffle 24, the center of the shelf member 41 is the drum ( The width 의 of the shelf member 41 and the angle R between the shelf member 41 and the leg member 42 are determined so as to coincide with the center of 12). In this embodiment, the angle R of the shelf member 41 and the leg member 42 is set to 90 degrees, and the width Ｗ of the shelf member 41 is the side surface 24a of the baffle 24 from the center of the drum 12. The length should be twice the horizontal distance to the base of the head.

Fig. 10 is an electric system block diagram of the drum laundry dryer. The control unit 50 is mainly composed of a microcomputer including a CPU, a ROM, a RAM, a timer and the like, and based on a control program stored in the ROM, operation operation of each round trip distance related to washing described later. Various controls are performed. The control unit 50 includes an operation key 7, a display unit 8, a water level sensor 52 for detecting the level of water accumulated in the outer tub 10, a temperature sensor 53 for detecting the temperature of water or air, and an operation. The buzzer 54 etc. which inform the completion | finish and an abnormality are connected. In addition, a load driver 51 is connected to the controller 50, and the motor 19, the blower motor 55, the heater 38, the water supply valve 56, and the dehumidification are provided via the load driver 51. The operation of the water supply valve 57 and the drain valve 27 is controlled.

Next, the stop drying course operation performed based on the above configuration will be described.

When performing a stop drying course, a user first installs a drying aid in the drum 12. At this time, a baffle 24 located near the bottom of the drum 12 is used for positioning the drying aid 40. That is, the user puts the drying aid 40 in the drum 12 from the laundry inlet 3, in a state that the leg member 42 on one side is in contact with the drum inner side 24a of the baffle 24, The drying aid 40 is placed on the bottom major surface of the drum 12. In this state, the shelf member 41 of the drying aid 40 is almost horizontal. In this way, installation of the drying aid 40 is completed. When the drying aid 40 is installed, the drum 12 is locked by the drum position fixing device 25. Therefore, even if the drying aid 40 strongly hits the baffle 24, there is no fear that the baffle 24 moves and the position is missed. When the installation of the drying aid 40 is finished, the user places the laundry to be dried on the shelf member 41. At this time, since the guide 43 exists in the circumferential direction of the drum 12, the clothing placed on the shelf member 41 is hard to fall off.

In this way, when the laundry is put in, the user selects the stop drying course by using the drying course key 7e. The driving end of this course is determined by time, and the user sets a desired driving time from the driving time which can be set in 10 minute intervals from 10 minutes to 90 minutes by the time setting key which is not shown in figure.

When the start key (7ｂ) is pressed, operation starts. The controller 50 continues to lock the drum by the drum position fixing device 25, and while the motor 19 (drum 12) is stopped, the heater 38, the blower motor 55, and the dehumidifying agent are used. The water supply valve 57 is turned on. The warm air blown into the drum 12 from the outlet 16a abuts on the upper and lower surfaces of the laundry, passes through the inside of the laundry, and goes out of the drum 12 from the exhaust port 12b and the water passage 12a. In this way, the laundry is dried without staining. During the drying, the control unit 50 turns on only one heater 38 to be in the [weak] state so that the temperature inside the drum 12 is 60 ° C. or less. This prevents the adhesive used for the shoe from falling even when the shoe (shoes) is dried. The higher the rotation speed of the brower motor 55 is, the lower the temperature of the warm air is. However, the initial stage of operation causes the brower motor 55 to rotate at a relatively low speed, for example, 3400 rpm. As a result, the temperature in the drum 12 is quickly increased. For example, when 5 minutes have elapsed from the start of operation, the blower motor 55 is rotated at a relatively medium speed, for example, 4000-4500 rpm, thereby slightly lowering the warm air temperature. In addition, when the drying rate of the laundry is about 90%, the blower motor 55 is rotated at a relatively high speed, for example, 4700 rpm to further reduce the warm air temperature. In this way, when the laundry is almost dry, by reducing the warm air temperature, it may be difficult to shrink even in laundry that is likely to cause felt shrinkage. In this manner, when the set operation time is reached, the control unit 50 turns off the heater 38, cools down by cold wind, and ends the operation when the temperature in the drum 12 decreases.

As described above, in the drum type dryer of the present embodiment, since the laundry is kept in a state having a space between the bottom main surface of the drum 12 by the drying aid 40, the warm air can be supplied to the upper or lower surface of the laundry. At the same time, the warm air can be passed through the inside, and the laundry can be dried without staining.

Furthermore, the drying aid 40 may be put into the drum 12 at the laundry inlet 3, and the leg member 42 may be placed on the bottom circumferential surface of the drum 12. Can be installed.

Furthermore, the user simply contacts the leg member 42 of the drying aid 40 with the side surface 24a of the baffle 24 and places it on the bottom circumferential surface of the drum 12 so that the shelf member 41 becomes horizontal. Furnace drying aids 40 can be installed. Therefore, the drying aid 40 can be easily installed in an appropriate state.

In addition, in order to determine the position of the drying aid 40, there is no need to provide a dedicated positioning member in the drum 12, and there is a fear that the laundry may be damaged such that the positioning member is caught in the laundry during washing or drying. none.

Furthermore, a drum type laundry dryer as a second embodiment of the present invention will be described. Fig. 11 is a side sectional longitudinal sectional view showing the internal structure of the drum type laundry dryer of the second embodiment. In this second embodiment, the same components as those in the first embodiment will be denoted by the same reference numerals and the description thereof will be omitted.

In the present embodiment, the detection aid 60 is provided for detecting that the drying aid 40 is provided in the drum 12. That is, the magnet 61 is located at the lower end of one leg member 42 which becomes the front side of the drum 12 when installed in the drum 12 among the leg members 42 at four places of the drying aid 40. On the other hand, a hall IC 62 for generating a signal corresponding to the magnet 61 is mounted on the outer bottom surface of the outer tub 10. The hall IC 62 is electrically connected to the controller 50.

In this way, when the driving | operation course which rotates the drum 12 other than the stop drying course was started by the control part 50, the drying auxiliary | assistance tool 40 is made to the drum 12 according to the signal from the hall IC 62. When it is detected that it is installed, the operation is stopped and the drum 12 is stopped. Then, the abnormal alarm is performed in accordance with the error display on the information display section 8b and the buzzer sound by the buzzer 54.

Next, in the second embodiment, only the configuration different from the drum type laundry dryer of the third embodiment in which the detection device 60 of the drying aid 40 is different will be described with reference to FIG. Fig. 12 is a side sectional longitudinal sectional view showing the internal construction of the drum type laundry dryer of the third embodiment.

The drying aid 40 of the third embodiment extends downward from the predetermined position of the shelf member 41, and drills through the bottom peripheral surface of the drum 12 when the drying aid 40 is installed into the drum 12. As shown in FIG. In the vicinity of the front and rear side surfaces of the recess 63 provided at the bottom of the outer tub 10, two detection wires 44 are provided which hold the tip portion. These detection wires 44 are connected and reinforced by one wire 45 extending in the horizontal direction.

In this way, a driving course for rotating the drum 12 with the drying aid 40 installed in the drum 12 is performed. When the drum 12 rotates, the tip of the detection wire 44 is the outer tub 10. It hits the front wall or the back wall of the recessed part 63 of the. As a result, rotation of the drum 12 is prevented. When the control unit 50 detects that the motor 19 is not rotating from a rotation sensor (not shown) for detecting the rotation speed of the motor 19, the drying aid 40 is installed. It is determined that 12) is locked, and the motor 19 is stopped to stop operation. Then, the abnormality alarm is performed by the error display on the information display section 8b and the buzzer sound by the buzzer 54.

As described above, according to the drum type laundry dryers of the second and third embodiments, when the detection aid 60 detects that the drying aid 40 is in the installed state, the operation is stopped and the drum 12 is stopped. It is stopped. Therefore, it is possible to prevent the drying aid 40 from being mixed inside the drum 12, thereby preventing damage to the drum 12 and the drying aid 40.
