2. Description of the Related Art Generally, there is a conventional bedding dryer disclosed in, for example, JP-A-7-80051. In the bedding processing apparatus described in this publication, a futon is hung in a folded state on a futon hanging device, housed in a closed drying room, and hot air heated by a burner is sent into the drying room to dry the room. Is held in a dry atmosphere for a predetermined time to dry the futon. Also,
In the dryer disclosed in Japanese Patent Publication No. 6-73591, a cylindrical drum having a large number of ventilation holes on the peripheral wall is used, and the futon stored in the drum is rotated.
Hot air is blown into the drum from the ventilation holes, and the bedding in the drum is dried while stirring.

[0003]

By the way, in the above-mentioned bedding processing apparatus in which a futon is hung on a futon hanger and the temperature of the atmosphere in the drying room is raised to dry the futon, the urethane foam of the batting or mattress is used. Itself has the same effect as thermal insulation, so the surface temperature of the futon or mattress rises and dries, but the hot air in the drying room does not easily reach the interior of the futon or mattress, and the internal temperature is unlikely to rise. As a result, there was a problem that the drying of the inside became insufficient or that the drying required a long time and could not be efficiently dried. In the case of a dryer that dries the bedding while stirring the bedding, the rotation of the drum causes the bedding to be violently agitated, whereby the filling of the bedding is likely to lose its shape and the cloth cover is liable to be damaged. There was a problem that the service life of the kind was shortened. The present invention relates to a bedding dryer and solves the above-mentioned problems. It is an object of the present invention to provide a bedding dryer that can efficiently dry bedding such as a futon or a mattress in a short time. .

According to the first aspect of the present invention, there is provided a bedding dryer for storing bedding such as futons and mattresses in a box-shaped drying chamber in a stationary state and drying the bedding. Drying air supply means for supplying drying air into the drying chamber, and supporting means for supporting the bedding so that the drying air can be dried by passing the drying air into the bedding using the air permeability provided by the bedding. It is provided with. According to this configuration, since the drying air actively passes from the surface to the inside of the bedding, the temperature inside the bedding is sufficiently increased, and the inside of the bedding can be dried firmly.

[0005] In the invention described in claim 2, the dry air supply means includes an outside air suction port, a heating means for heating the outside air taken in from the outside air suction port, and an air heated by the heating means. A discharge port for charging the drying chamber; a suction port for exhaust provided in the drying chamber; and a blower for sucking air taken into the drying chamber from the discharge port through the suction port and discharging the air to the outside. And with. According to this configuration, when the air is sucked by the blower, the drying chamber has a negative pressure, and the outside air heated by the heater is supplied to the drying chamber. Further, in the invention according to claim 3, the support means is made of a member having air permeability,
The bedding is placed on the support means so as to block dry air flowing into the drying chamber. According to this configuration, since the supporting means is made of a member having air permeability, the drying air that reaches the bedding is not blocked by the supporting member, and the drying is favorably performed. Further, in the invention described in claim 4, the support means can be a plate-shaped member bent and formed in a substantially inverted U-shape. According to this configuration, when the bedding is placed on the support means, the bedding does not easily wrinkle, so that the finish after drying is improved. Claim 5
In the invention described in (1), the drying air supply means is provided with the discharge port above the bedding and the suction port below the bedding.

According to this configuration, since the drying air supplied from the discharge port into the drying chamber is directly blown to the bedding, the drying air passes through the support member or the ventilation path before the drying air reaches the bedding. In addition, the heat of the drying air is not deprived, and the heating efficiency is further improved. In the invention according to claim 6,
The drying air supply means is provided with the discharge port below the bedding and the suction port above the bedding so that air passing through the bedding flows in a direction opposite to gravity. According to this configuration, when the dry wind passes through the bedding,
Since the fluid flows in the opposite direction to the gravity, the pressure applied to the bedding is reduced, and the inside of the bedding after drying becomes soft and finished. In the invention according to claim 7, the support means is provided so as to be able to protrude and retreat from the drying chamber in a substantially horizontal direction. According to this configuration, since the support member can be put in and taken out of the drying chamber, it becomes easy to set and remove the bedding to and from the support member.

Thereby, the placing member 11 can be pulled out of the drying chamber 2 through the access port of the drying chamber 2, and the placing member 11 is pulled out of the drying chamber 2, and the bedding 13 is placed thereon. It becomes possible to set it on the placing member 11 or take out the bedding 13 after the drying is completed. On the upper surface of the base 15, an opening 15a communicating with the internal space 11a of the placing member 11 is provided. An introduction hole 15b communicating with the opening 15a is provided on both side walls of the base 15, and when the base 15 is set at a predetermined position in the drying chamber 2, the suction of the drying chamber 2 is performed. The introduction hole 15b is located at a position facing the mouth. Reference numeral 18 denotes a sealing member made of, for example, felt, which is interposed between the side surface of the base 15 and the inner wall surface of the drying chamber 2 to increase the airtightness of a connection portion between the suction port 4 and the introduction hole 15b. The inside of the bedding 13 is not discharged without passing through the inside of the bedding 13. still,
In the present embodiment, two placing members 11 are provided side by side, and two beddings 13 are provided on each placing member 11, one by one.
However, the present invention is not limited to this, and one or three or more mounting members 11 may be provided. Next, the operation will be described. After the door 5 of the drying chamber 2 is opened and the placing member 11 is pulled out from the drying chamber 2 forward, the bedding 13 is set on the placing member 11 described above. After the placing member 11 is returned into the drying chamber 2 and the door body 5 is closed, the user performs a predetermined operation to start the drying operation.

When the drying operation is started, the heater 6 and the fan 8 start operating. A temperature sensor, a humidity sensor, and the like (not shown) for detecting the temperature and humidity of the air are provided in the drying chamber 2, and a control unit (not shown) receives a signal from each sensor and controls the inside of the drying chamber 2 The heater 6 and the fan 8 are controlled so that the temperature and humidity of the drying air are in a predetermined state.

When the fan 8 rotates, the air flows out of the drying chamber 2 through the suction port 4 and is discharged to the outside through the ventilation path 9, while the air is taken in from the outside air suction port 7 and passes through the heater 6. Drying room 2 through discharge port 3
Flows into. The air flowing into the drying chamber 2 is heated by the heater 6 to become hot air, and reaches the upper surface of the bedding 13 stored in the drying chamber 2. The warm air blown to the surface of the bedding 13 passes through the interior of the bedding 13 due to the air permeability of the bedding 13 and passes through the through hole 1 formed in the placing member 11.
2 flows into the internal space 11 a of the mounting member 11 through the second member 2.
When the bedding 13 passes, the warm air heats the inside of the bedding 13 and evaporates the moisture of the bedding 13. The vaporized water mixes with the warm air passing through the bedding 13, flows into the internal space of the mounting member 11, passes through the inside of the base 15 through the opening 15 a of the base 15, and passes through the introduction hole of the base 15. 15b, the air is sent to the fan 8 through the suction port 4 of the drying chamber 2 and the ventilation path 9, and then discharged from the exhaust duct 10.

As described above, the control means (not shown) controls the heater 6 and the fan 8 according to the control signals from the respective sensors, and ends the drying operation when a predetermined time has elapsed from the start of the operation. At this time, if necessary, a so-called cool-down operation of stopping the heater and supplying cool air to the drying chamber may be performed to cool the bedding to a predetermined temperature. As described above, according to the embodiment, the bedding 13
Is provided so as to be able to block the warm air, so that the warm air actively passes through the inside of the bedding 13 and evaporates and removes the moisture of the bedding 13, so that the drying of the bedding 13 is effective. Will be performed. In addition, since the outlet 3 for hot air is provided above the bedding 13, the hot air supplied from the outlet 3 into the drying chamber 2 is directly blown onto the bedding 13.
Therefore, since the hot air does not pass through the placing member 11 and the ventilation path 9 before reaching the bedding 13, the heat of the hot air is not taken away by the placing member 11 and the return path 9, so that the heating efficiency is improved. In addition, since the placing member 11 is bent in a substantially inverted U-shape (the bent portion is curved), when the bedding 13 is set on the placing member 11, a force is applied to a local portion of the bedding 13. Since wrinkles and wrinkles are prevented, the finish after drying is improved.

Further, the placing member 11 protrudes from the drying chamber 2,
Since it is configured to be retractable, it is easy to set and remove the bedding 13 on the placing member 11. Next, FIG. 5 is a front sectional view showing another embodiment of the bedding dryer according to the present invention. In this embodiment, the hot air passing through the bedding 13 is configured to flow upward. That is, in this configuration, the outlet 19 for the warm air is formed at the lower part of both side walls of the drying chamber 2, and the suction port 20 for exhausting the drying chamber 2 is provided on the upper wall of the drying chamber 2. . Therefore, when the drying operation is started and the heater 6 and the fan 8 are driven, the air in the drying chamber 2 is sucked upward through the suction port 20 as shown by the arrow in the figure, and
While being discharged through the exhaust duct 10, the outside air heated by the heater 6 is sent downward through the ventilation passage 9 formed between both side walls of the drying chamber 2 and both side walls of the housing 1. The hot air is supplied from the hot air outlets 19 at the bottoms on both sides of the drying chamber 2 to the internal space 11 a of the mounting member 11 via the base 15. The hot air supplied to the internal space 11a of the mounting member 11 increases the pressure of the internal space 11a,
Hot air uniformly flows through the bedding 13 and flows into the drying chamber 2 through the through holes 12 of the placing member 11. When the hot air passes through the beddings 13, the inside of the beddings 13 is sufficiently heated to evaporate the moisture of the beddings 13, so that the beddings 13 are securely dried to the inside. Then, in this embodiment, the hot air passing through the bedding 13 flows upward. That is, when the hot air passes through the bedding 13, it flows in the opposite direction to the gravity, so that the pressure in the same direction as the gravity is not applied to the batting of the bedding 13. Act), and the bedding 13 after drying is finished softly to the inside.

[0012]

As described above, according to the bedding dryer of the present invention, since the drying air actively passes through the bedding such as a futon or a mattress, the drying air is blown to the inside of the bedding. Finally, the inside of the bedding can be sufficiently dried. Further, the time required for drying is short, and time and operating costs can be saved. Further, since the bedding is placed on the supporting means and drying is performed, the bedding does not lose its shape. Further, by forming the support means in an inverted U shape, wrinkles and the like can be prevented without applying excessive force to the bedding placed on the support means, and the finish after drying becomes good. Further, by providing the outlet for the warm air above the bedding, the dry air flowing into the drying chamber from the outlet is directly supplied to the bedding. Accordingly, heating efficiency is improved, and time and operating costs can be further reduced.

Furthermore, when the drying wind passes through the bedding, the structure is made to flow in the direction opposite to the gravity, so that the pressure in the same direction as the gravity is not applied to the batting of the bedding, and the bedding after the drying is applied to the bedding. It will be finished to the inside softly.
