Description

TECHNICAL FIELD The present invention relates to an apparatus for storing and drying a futon.

[Background Art] As a conventional futon dryer, an electric heater b, an electric heater c, and a fan d are installed in a dryer main body a as shown in FIG. 2, and the dryer main body a and an air mat e are connected to each other. There is something. When drying with this, an air mat e is sandwiched between the comforter 1a of the comforter 1 and the mattress 1b, and warm air is blown from the dryer main body a for drying. However, with this structure, it is easy to ignite due to dust or the like in the dryer main body a, and there is a risk that even the fire that is ignited due to dust or the like will easily burn to the dry futon 1. More specifically, it has the following drawbacks.

I). The dryer body a is provided with a filter f,
Very fine dust (nonflammable dust is fine, but fine flammable dust such as cotton is worn away) passes through the filter f, and the electric heater b also attaches to the electric motor c and the air passage, and ignites. To do. The temperature of the hot air is controlled to 70 to 80 ° C or lower, but the temperature of the surface of the electric heater b is around 200 ° C, and the carbonization of the attached dust progresses, which may cause a fire. There is Generally 100 cold fires
It is said to occur around ℃.

B). The electric motor c does not normally generate heat,
When an abnormality occurs, heat may be generated from the coil itself, the temperature may increase due to the wear heat of the bearing, and a fire (for a short time) may occur, or a low temperature fire may occur after a long time. Although a thermal fuse is often provided, it cannot be said to be 100% safe and reliable due to dust and other causes.

Further, as a futon dryer of the prior art considered by the present inventors, there is one shown in FIGS. 3 and 4. This is provided with a warm air circulation path 3 on the outer circumference of the futon drying chamber 2, a hot water heat exchanger 4 as a heat source in the warm air circulation path 3 and a fan 5 as an electric motor for driving the fan 5. Motor c
Is used. If you want to dry Futon 1 with this, comforter
A futon 1 such as 1a, a mattress 1b, and a blanket 1c is housed in a futon drying chamber 2, hot water is supplied to the hot water heat exchanger 4, and a fan 5 is driven by an electric heater c. Then, warm air is generated, and the upper air outlet 6 and the lower air outlet 7 are discharged from the warm air circulation path 3.
Hot air is blown to the futon 1 in the futon drying room 2 through
The warm air returns from the intake port 8 to the warm air circulation path 3, is heated again, and is sent into the futon drying chamber 2. In such a system, since the heat source is the hot water heat exchanger 4, the risk of a low-temperature fire is reduced, but the risk of a fire from the electric motor c, a control circuit, or a safety device remains 100%. This is not safe, and even if a filter is installed in the air duct because it is a recirculation type, more dust will be trapped in the air duct and there is a possibility of fire.

[Object of the Invention] The present invention has been made in view of the above-mentioned points, and an object of the present invention is to ignite an ignition source (electrical device) near a futon drying chamber containing a futon. Etc.) does not exist, so there is no need to worry about fire.

DISCLOSURE OF THE INVENTION In the futon dryer of the present invention, a warm air circulation path 3 is provided on the outer periphery of a futon drying chamber 2 in which the futon 1 is stored, and warm air is circulated through the warm air circulation path 3 and the futon drying chamber 2. In the case where the futon 1 is dried, a hot water heat exchanger 4 as a heat source is arranged in the warm air circulation passage 3 and a fan 5 using a fluid motor 9 as a motor is arranged in the warm air circulation passage 3. Therefore, the above-mentioned configuration solves the drawbacks of the conventional example. That is, since the hot water heat exchanger 4 as a heat source is arranged in the warm air circulation path 3 and the fan 5 using the fluid motor 9 as a motor is arranged in the warm air circulation path 3, it is possible to control the temperature without electrical means. Since there is no ignition source (electrical equipment etc.) that causes a fire in the vicinity of the futon drying chamber 2 due to the generation of wind, there is no fear of a fire at all.

Hereinafter, the present invention will be described in detail with reference to Examples.

As shown in FIG. 1, the futon drying chamber 2 is formed by a ceiling panel 11, a side panel 12, a bottom panel 13, and a rear panel, which are assembled into a rectangular box shape with a front opening, and a front opening is provided with an openable door. ing. The ceiling panel 11, side panel 12, and bottom panel 13 are hollow panels, and the hot air circulation path 3 is formed in the hollow portions. Bottom panel
A futon drying room 2 is provided in the center of the futon placing plate 14 which is the inner surface plate of 13.
A lower outlet 7 is provided for communicating the inside with the hot air circulation path 3. An upper outlet 6 is provided in the upper part of the futon drying chamber 2 so that the inside of the futon drying chamber 2 and the warm air circulation path 3 communicate with each other.
A bellows tube 15 is provided at the upper outlet 6, and a contact portion 15a is provided at the lower end of the bellows tube 15. In the bottom panel 13, the hot air circulation passage 3 has a hot water heat exchanger 4 as a heat source, a fan 5, and a fluid motor 9 serving as a motor for driving the fan 5.
Is decorated. A drive unit storage box body 16 formed of a non-combustible material such as metal is arranged at a position separated from the futon drying chamber 2, and in the drive unit storage box body 16, a fluid pressure pump 17, an electric motor 18, An electric control panel 19, a solenoid valve 20, etc. are installed inside. The hot water heat exchanger 4 is connected to the boiler via a hot water supply pipe 21, and hot water of about 80 ° C. is supplied to the hot water heat exchanger 4. Solenoid valve inside drive unit housing 16
20 is inserted in the hot water supply pipe line 21, and the solenoid valve 20 can be controlled by the electric control panel 19. The fluid motor 9 and the fluid pressure pump 17 are communicated with each other through a fluid supply line 22, and the fluid pressure pump 17 is driven by the electrical motor 18 under the control of the electrical control board 19 to fluidize a fluid such as water. Motor 9
The fan 5 can be driven.

Then, when the futon 1 is dried, the futon 1 such as the comforter 1a, the mattress 1b, and the blanket 1c is housed in the futon drying chamber 2, the electric motor 18 is driven, and the solenoid valve 20 is opened.
Then, hot water is supplied to the hot water heat exchanger 4 and the fluid is sent to the fluid motor 18 to rotationally drive the fan 5,
Hot air is generated. The warm air is blown from the warm air circulation path 3 into the futon drying chamber 2 through the upper blowing port 6 and the lower blowing port 7, passes through the futon 1, and then returns from the intake port 8 to the warm air circulating path 3 to be heated again. Being circulated as well.

The structure of the futon dryer according to the present invention can be used not only for drying the futon but also for drying clothes or those that may burn (for example, those containing an organic solvent).

[Advantages of the Invention] As described above, according to the present invention, a hot water heat exchanger as a heat source is arranged in the warm air circulation path, and a fan using a fluid motor as a motor is arranged in the warm air circulation path. There is no ignition source (electrical equipment, etc.) that causes a fire in the vicinity of the futon drying room, and there is no danger of fire, and hot water is used as the heat source. However, since the motor uses a normal temperature fluid, lint, dust, etc. adhere to it and carbonize it even after a long period of time.
There is no risk of the temperature rising above ℃.
