Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a closet dryer for drying the inside of a closet.

In general, closets tend to have closed doors and have extremely poor ventilation, so the inside of the closet tends to get damp and mold grows, and the same goes for the things stored there. For this reason, it is necessary to dry the inside of the closet regularly,
To date, there has been no dryer specifically designed for closets; therefore, there have been no dryers for drying the inside of closets, for example,
It is easy to think of using a so-called futon dryer comprising a warm air fan, a blower pipe, etc. as shown in Japanese Patent No. 5333, Japanese Patent No. 48-5334, and Japanese Patent No. 48-26236. However, when using such a futon dryer, if the hot air blower could be placed inside the closet, it would be possible to dry the futon by keeping the closet door closed and preventing hot air from escaping, but in reality, the futon dryer would not fill the closet completely. In many cases, futons, etc. are stored, and there is no room to store the hot air fan.Furthermore, there are problems such as lack of safety due to air exchange and the way it is used, so it is recommended to store the hot air fan in a closet. It is possible to use it by placing it outside. However, in this case, the tip of the hot air blower pipe is placed inside the closet to dry, so the blower pipe gets in the way and the closet door cannot be closed completely. It must be dried with the diameter of the container open. For this reason, even if hot air is desperately supplied into the closet, the hot air escapes through the half-opened part of the door before sufficiently removing moisture, making it impossible to dry the closet efficiently. Also, since the air inside a closet is inherently humid, even if you could store a warm air fan inside the closet and close the door completely, the humid air would be turned into hot air and the closet would simply be closed. Efficient drying cannot be expected just by circulating the inside.

The present invention has been made in view of the above-mentioned conventional circumstances, and an object thereof is to provide a closet dryer that can efficiently dry the inside of a closet.

Embodiments of the present invention will be described below with reference to the drawings. First, in FIGS. 1 to 5 showing the first embodiment, 1 is a dryer main body, and the outer shell of this dryer main body 1 is a flat outer shell whose rear opening is closed by a sealing plate 2.

Reference numeral 19 denotes an air volume adjustment device, which has an operating shaft 21 that passes through the outlet body 10 via a sealing member 20, and a penetrating protruding base portion of the operating shaft 21 is attached to the outlet body 10 with a bolt 18. The operating shaft 2 is
1, an adjustment plate 23 is fixedly located within the outlet body 10. In particular, 24 shown in Figures 2 and 3.
A spring support stand supports a V-shaped leaf spring 25, and an air volume adjustment lever 26 is fixed to the end of the operating shaft 21 facing the leaf spring 25.
An engaging portion 27 that engages and disengages from the top of the leaf spring 25 in stages is provided on the outer periphery of the base end side of the air volume adjustment lever 26.
For example, it is formed into three stages. Reference numeral 28 denotes an opening formed in the front surface of the outer box 3, and the tip of the air volume adjustment lever 26 projects through this opening 28.
Reference numeral 29 denotes an outside air intake port formed on the upper wall of the outer box 3. A holding frame 30 is supported by screws at the lower part of this upper wall so as to face the outside air intake port 29. is formed with openings 31, 31 and a connecting port 32, and the connecting port 3
A lower end portion of a return suction port body 33 bent into an L-shape is rotatably fitted and connected to 2. 34 is a filter, which is supported by rails 35, 35 (not shown in FIG. 1) and is connected to the outside air intake port 29.
are opposed to each other via the holding frame 30, and the handle 36
By sliding on the rails 35 by the operation, the outer box 3 can be put in and taken out through a long opening 37 formed on the front surface thereof. Reference numeral 38 denotes an L-shaped discharge port body, the upper end of which is fitted and connected to the lower end of the one 9 through a sealing member 39 . On the other hand, in FIGS. 4 and 5, 40 is a room wall, 41 is a wall of a closet 42, and 43 is a door such as a sliding door provided in a door frame 44 of the closet 42 to open and close it. The door frame 4 is a closet 42
The left and right pillars 4 form the opening for loading and unloading goods.
5 (only one of which is shown), a sill 46, and a lintel 47. Note that 48 is a ceiling plate of the closet 42, 49 is a floor plate, and 50 is a partition shelf that partitions the closet 42 into upper and lower parts. Now, 51 is a vertically long closing plate, and an air release port 52 is formed at the top of this to naturally release the air inside the closet 42, and this closing plate 51 has a substantially central part and a part near the bottom end. An upper hole 53 and a lower hole 54 are respectively formed in the
Further, on the back side of the closing plate 51, as shown in FIG. 5, a ventilation passage 56 is formed by a gutter plate 55. This ventilation passage 56 starts slightly below the air outlet 52 and extends to end at a position that includes the upper hole 53, and a large number of through holes 5 and 7 are formed in the upper part of the gutter plate 55. . Such a closing plate 51
is supported in an upright state by using the door grooves of the sill 46 and lintel 47 in the empty space on the pillar 45 side formed by slightly opening the door 43 in the door frame 44. Therefore, if the door frame 44 is moved until the door 43 comes into contact with the right side of the closing plate 51, the door 43 and the door frame 44 in the half-open state will be separated.
The space between the two is closed by the closing plate 51. On the other hand, as shown in FIG. 4, the dryer main body 1 is suspended from the chamber wall 40 adjacent to the closing plate 51.
Then, one end of the return hose 58 is connected to the inlet of the return suction port body 33, and the other end is connected to the upper hole 53 of the closing plate 51, thereby inserting the return suction port body 33 into the closet 42. It communicates. Further, one end of the discharge hose 59 is connected to the outlet of the discharge port body 38 and the other end is connected to the lower hole 54, thereby communicating the discharge port body 38 into the closet 42. still,
Reference numeral 60 is a power switch for controlling power on/off of the motor 7 and the positive temperature coefficient thermistor 14, and 61 is a pilot lamp, which are provided on the front surface of the outer box 3 of the dryer main body 1.

Next, the operation of the above configuration will be explained. Now, when the power switch 60 is operated to energize the motor 7 and the PTC thermistor 14, the fan 8 is rotated by the motor 7, and the PTC thermistor 14 is rotated by the motor 7.
is generated. And when fan 8 is rotated,
Due to the suction action, the air in the closet 42 is introduced into the outer box 3 via the return hose 58, the return suction port 33, and the filter 34, and the outside air in the room 62 where the dryer main body 1 is placed. Air is also introduced through the outside air inlet 29, opening 31, and filter 34 of the outer box 3, and the air thus introduced into the outer box 3 is further sucked into the casing 5 via the intake port 6. After that, the suction port 1 of the casing 5
At this time, the discharged air is heated by the positive temperature coefficient thermistor 14 to become warm air, and this hot air is discharged from the other outlet body 9 and the outlet body 14. Outlet body 38
The liquid is then discharged and supplied to the space below the partition shelf 50 in the closet 42 via the discharge hose 59 . After this, the warm air is directed to the space below the partition shelf 50, especially to the floorboard 4.
9, move to the space above the partition shelf 50 as shown by the arrow 63 and remove the moisture around it, and then remove the moisture around the partition shelf 50 as shown by the arrow 64.
The air flows into the ventilation passage 56 through the through hole 57 formed in the hose 5, and descends within the ventilation passage 56 to form the return hose 5.
3 and is returned to the return suction port body 33 from this return hose 58 and returned to the outer box 3. The inside of the closet 42 is dried by this operation, and during this drying operation, a portion of the warm air with high absolute humidity after removing the moisture inside the closet 42 is transferred to the top of the closing plate 51. The outside air with low absolute humidity is naturally released into the room 62 from the air outlet 52 formed at
From there, it is sucked into the casing 5 through the intake port 6. Therefore, according to the above structure, even if the door 43 is in a half-open state during drying, the space between the door 43 and the door frame 44 is closed by the closing plate 51, so that the door cannot be closed as in the conventional case. Unlike those that had to dry with a gap left between the door frame and the door frame, I have never had a case where my clothes ran out of the closet 42 before the warm air had sufficiently removed the moisture. Moreover, since the hot air can be repeatedly heated and circulated between the inside of the closet 42 and the dryer main body 1, a flow of warm air can be reliably generated inside the closet 42 while effectively utilizing the hot air. As a result, the warm air can be brought into sufficient contact with the wall 41 of the closet 42 and the stored items (not shown). Moreover, in addition to circulating hot air between the dryer body 1 and the closet 42, a portion of the warm air with high absolute humidity inside the closet 42 is released from the air outlet 52 into the room 62,
Instead, outside air with low absolute humidity is introduced into the blower 4, warmed by the positive temperature coefficient thermistor 14, and supplied to the closet 42, thereby suppressing the absolute humidity of the circulating warm air from increasing excessively. In combination with the above-mentioned circumstances, the inside of the closet 42 can be efficiently dried and the drying time can be shortened.

According to this embodiment, if the inclination angle of the adjustment plate 23 is set as shown by the chain double-dashed line in FIG. 1 by rotating the air volume adjustment lever 26, the air is discharged from the outlet body 10. The amount of air can be set in accordance with the above-mentioned inclination angle, and the amount of hot air commensurate with the humidity of the closet 42 can be supplied. In this case, since the heat source is the PTC thermistor 14, its calorific value changes depending on the amount of air passing through it.
The temperature of the hot air can also be controlled by the rotation setting, and the temperature can be set according to the outside air or the humidity inside the closet 42.

FIG. 6 shows a second embodiment of the present invention.
The same parts as those in the figure are given the same reference numerals. That is, the sixth
In the figure, there is only one opening 31 provided opposite the outside air intake port 29 of the outer box 3, and although detailed illustration is omitted, the switching plate 67 as a switching device 66 can be operated from the outside. A desiccant attachment plate 68 is provided in the air intake path of the blower 4, for example, on the filter 34, and is movably provided so as to selectively face and close the opening 31 and the lower end of the return suction port body 33. The configuration is such that it is provided integrally. According to this configuration, when the humidity inside the closet 42 is extremely high and the humidity of the outside air is extremely low, the return inlet body 33 is closed by the switching plate 67 and dry operation is performed, and ventilation is performed using dry warm air. So it's convenient. Furthermore, when the outside air is extremely humid, such as during the rainy season, if the opening 31 is closed off by the switching plate 67 and only the warm air is circulated between the closet 42 and the dryer body 1, it is possible to prevent the air from entering the dryer from outside. This eliminates the introduction of moisture, which is convenient when drying the closet 42 together with the futon inside. By changing the position of the switching plate 67, the ratio between the amount of return air from the return inlet body 33 introduced into the outer box 3 and the amount of outside air from the opening 31 can be set as appropriate. In addition, since the filter 34 has the desiccant attachment plate 68, the air introduced into the outer box 3 absorbs moisture by the desiccant included in the desiccant attachment plate 68.
You can expect even more effective drying.

Next, a third embodiment will be described with reference to FIGS. 7 and 8, in which the same parts as in FIG. 4 are denoted by the same reference numerals. In FIG. 7, reference numeral 69 denotes a drying reinforcement frame, which has a rectangular main body 70 with open upper and lower surfaces, and a large number of through holes 72 to form a warm air chamber 71 in the front of the frame. In addition to providing the perforated plate 73, a large number of partition plates 74 whose remaining spaces within the frame extend perpendicularly from the perforated plate 73 are provided intermittently to form a large number of air guide paths 75. 76 is a large number of through holes 7
7 is formed on the bottom plate and is laid on the upper surface of the main body frame 70 so as to cover the entire open part thereof. However, the portion of the bottom plate 76 facing the warm air chamber 71 should be made non-porous, or the upper surface of the hot air chamber 71 should be closed in advance with another non-porous plate. Place such a drying reinforcement frame 69 on a part of the closet 42 that you want to dry particularly well, for example, on the humid floorboard 49, and connect the lower hole 54 of the closing plate 51 to the connection port 71a led out from the warm air chamber 71. The discharge hose 59 of the dryer main body 1 introduced through is connected. Then, the hot air discharged from the dryer main body 1 through the discharge hose 59 and the connection port 71a is uniformly dispersed within the warm air chamber 71 of the drying reinforcement frame 69, and then passes through the through holes 72 of the perforated plate 73. is supplied into each air guide path 75 through the air guide path 75 .
Since the lower surface of the container is open, moisture is removed from the floor plate 49 of the closet 42 and discharged from the through hole 77 of the floor plate 76. After the discharged hot air removes the moisture in the closet 42, it is returned to the dryer main body 1 via the return hose 58. In this way, the forced drying of the closet 42, especially the portion near the floor, is performed. still,
The inner diameter of the perforated hole 72 of the perforated plate 73 increases as the distance from the connection 71a increases, and the inner diameter of the perforated hole 77 of the bottom plate 76 increases as the distance from the perforated plate 73 increases. It goes without saying that there is no harm in trying to make the values even more uniform.

FIG. 9 shows a fourth embodiment, in which the internal structure of the dryer main body 78 is similar to that of FIGS. 1 and 2, and a return suction port body 79 and A discharge port body 80 is formed in the outer box 81 by an opening means, and the dryer main body 78 is inserted into the closing plate 82 arranged in the door frame 44 so that its return suction port body 79 and discharge port body 80 are inserted into the closet 42. It is configured so that it is positioned and supported.
In FIG. 9, parts corresponding to those in FIG. 4 are given the same reference numerals.

As described above, in the present invention, even if the door is half-open during drying, the space between the door and the door frame is closed by the closing plate, so unlike the conventional method, warm air is sufficiently There has never been a time when I ran out of the closet before the moisture was absorbed. Moreover, since the hot air can be repeatedly heated and circulated between the inside of the closet and the main body of the dryer, it is possible to reliably generate a flow of warm air inside the closet while effectively using the hot air. This allows the hot air to come into sufficient contact with the walls and contents of the closet. Moreover, part of the warm air with high absolute humidity inside the closet is naturally released from the air outlet of the closing plate, and in its place, outside air with low absolute humidity is drawn in from the outside air intake of the dryer body. Since it is mixed with the circulating hot air, it is possible to prevent the absolute humidity of the circulating hot air from increasing excessively, and together with the above-mentioned circumstances, it is possible to efficiently dry the inside of the closet and shorten the drying time. It is possible to provide a closet dryer that exhibits excellent effects.
