BACKGROUND OF THE INVENTION
The present invention relates to a futon dryer for drying futons and the like with warm air.
[0002]
[Prior art]
A conventional futon dryer has a main body divided into two vertically by a partition, provided with an electrical part having a hot air generator on one side, and provided with a storage part for storing a drying bag on the other side, and communicated with the hot air generator.

[Problems to be solved by the invention]
The conventional futon dryer is configured so that after drying of the futon and the like, the drying bag and the connecting member connecting the drying bag and the main body are appropriately folded or folded to be stored in the storage unit. . However, when the drying of the futon or the like is completed, the fan motor and the heater of the hot air generator are turned off at the same time, so the fan stops in a state where the heater is not sufficiently cooled. For this reason, the remaining heat of the heater flows into the connecting member and the drying bag connected to the hot air outlet by the rising airflow, and the connecting member and the drying bag are exposed to a high temperature. As a result, the connecting member and the drying bag continue to be in a high temperature state even after drying is completed, and cannot be stored in the storage unit, and may be thermally deformed in some cases.
[0005]
Also, when an abnormality occurs such as when the fan of the hot air generator does not rotate during drying, only the heater is energized, although the heater is equipped with a safety device, but the temperature at which the safety device operates normally Since it is set to a high temperature, it takes a certain amount of time for the safety device to operate, during which air heated by the heater flows into the connection member and the drying bag by the rising airflow, and the connection member and There was a problem that the dry bag was thermally deformed.
[0006]
Therefore, it is conceivable to take the distance between the heater and the hot air outlet and cool the remaining heat (air) between them, but the overall structure of the futon dryer becomes large, which makes the handling expensive and inconvenient. There was a fear. If such a structure is used, there is a possibility that the structure will be further enlarged when the power consumption is increased to shorten the futon drying time.
[0007]
The present invention was made in order to solve the above-described problems, and is an easy-to-use futon drying that can suppress the enlargement of the entire structure and prevent the flow of residual heat to the connecting member side after the drying is completed. The purpose is to get a chance.
[0008]

A drying bag 18 is provided, and when not in use, the connection member 17 bent in an approximately L shape and a properly folded drying bag 18 are accommodated. The connecting member 17 is made of a thermoplastic material.
[0013]
In the first embodiment configured as described above, when drying the futon, first, the storage lid 19 is opened with the main body 1 of the futon dryer standing, and the connecting member 17 and the drying bag 18 in the storage chamber 5 are opened. And the dry bag 18 is placed between the futon and the hanging futon. Next, when the operation unit 21 provided on the main body 1 (the front case 2 side) is operated, the motor 7 and the heater 10 are energized, the outside air is taken into the blower generator 9 and sent to the heater case 12. The outside air is warmed in the heater case 12 to become warm air, and is sent to the connection member 17 from the warm air outlet 13 a of the warm air discharge pipe 13. At this time, each shutter piece 14a, 14b of the shutter 14 provided in the warm air discharge pipe 13 (warm air outlet 13a) is rotated by the wind pressure around the shutter shafts 15a, 15b until it hits the stopper 16, and the warm air blowing is performed. The outlet 13a is opened. Next, the warm air sent to the connection member 17 blows out from the entire surface of the drying bag 18 and passes through the quilt and the quilt to remove each moisture. This is performed for a predetermined time, and each futon is dried.
[0014]
When drying for a predetermined time is completed, the air blowing device 9 and the heater 10 are automatically turned off simultaneously. At this time, each shutter piece 14a, 14b of the shutter 14 that has been rotated upward by the wind pressure returns to its original state by its own weight, and the warm air outlet 13a is closed, and the remaining heat by the heater 10 that has not yet cooled down. Is prevented from flowing into the connecting member 17 side. Then, the drying bag 18 installed between the quilt and the quilt is taken out, and the connecting member 17 is folded in a substantially L shape while being stored in the storage chamber 5 while folding the drying bag 18 to an appropriate size. The storage lid 19 is closed.
[0015]
Further, when the main body 1 of the futon dryer is laid down and used, first, after opening the storage lid 19 and taking out the connecting member 17 and the drying bag 18, as shown in FIG. The rear case 3 is slowly lowered so that the rear case 3 faces the floor surface F with the protrusion 22 provided at the lower part as a fulcrum, and the main body 1 is inclined by a handle 23 formed in a front arc shape used when carrying the main body 1. Support the state. At this time, since the first and second shutter shafts 15a and 15b are substantially parallel to the floor surface F, as shown in FIG. 6, the first and second shutter shafts 15a and 15b are located on the floor surface F side (lower side). The second shutter pieces 14a and 14b are opened by their own weights (the lower half of the hot air outlet 13a is opened), and the first and second shutter pieces 14a and 14b are located on the side away from the floor F (upper side). The shutter pieces 14a and 14b are closed by their own weights (a state where the upper half of the hot air outlet 13a is closed).
[0016]
Next, when the operation unit 21 is operated by placing the drying bag 18 between the futon and the hanging futon as in the case of using the main body 1 in a standing state, the motor 7 and the heater 10 are energized to dry the hot air. It is sent to the bag 18 and each futon is dried. At this time, the first and second shutter pieces 14a and 14b located on the upper side closed by their own weight are also rotated by the wind pressure, and the warm air outlet 13a is fully opened. Then, when the drying is finished and the air blowing device 9 and the heater 10 are automatically turned off simultaneously, the first and second shutter pieces 14a and 14b located on the upper side are brought into their original states ( Returning to the closed state, the upper half of the hot air outlet 13a is closed to make it difficult for the remaining heat from the heater 10 that has not yet cooled down to flow into the connecting member 17 side. The first and second shutter pieces 14a and 14b located on the lower side open the lower half of the hot air outlet 13a by their own weights, but the first and second shutter pieces 14a and 14b located on the upper side are opened. 14b makes it difficult for the remaining heat to flow, and it is possible to earn time for flowing in, so that it can be cooled during that time.
[0017]
Then, the drying bag 18 installed between the quilt and the quilt is taken out, the main body 1 is raised and brought to the original state, and the drying bag 18 is folded into an appropriate size and stored in the storage chamber 5. The connecting member 17 is bent in an approximately L shape while the storage lid 19 is closed.
[0018]
Thus, since the shutter 14 for opening and closing the hot air outlet 13a by the wind pressure is provided in the hot air discharge pipe 13, immediately after the drying is finished, the air blowing generator 9 and the heater 10 are turned off at the same time as the air flow is turned off. Each of the shutter pieces 14a and 14b returns to its original state by its own weight, and the hot air outlet 13a can be closed. Thereby, it is possible to prevent the remaining heat from flowing into the connecting member 17 side by the heater 10 which has not been cooled immediately after the drying is finished, and it is possible to prevent thermal deformation of the connecting member 17 and the drying bag 18. In addition, since the distance between the heater 10 and the hot air outlet 13a can be shortened as much as possible, the structure of the main body 1, that is, the futon dryer as a whole can be made compact, and a convenient futon dryer that is easy to handle while reducing costs. Obtainable.
[0019]
Further, even when the main body 1 is used in the state where the main body 1 is laid down, the shutter pieces 14a and 14b located on the upper side reliably close half of the hot air outlet 13a, so that it is difficult for the remaining heat from the heater 10 to flow into the connecting member 17 side. In addition to being able to gain time to flow into the connecting member 17 side, it is possible to cool the remaining heat during that time, prevent thermal deformation of the connecting member 17 and the drying bag 18, and prevent an increase in the overall structure. Can do. Further, even if the main body 1 is turned over and an abnormality of the air blowing generator 9 (fan 8 stops) occurs, the shutter pieces 14a and 14b located on the upper side reliably close half of the hot air outlet 13a, so that the same as above The effect of can be obtained.
