Description

[Detailed description of the invention] [Industrial application field] This invention relates to a hot air supply device that can dry futons and tatami mats, for example.

[Conventional technology]

FIG. 4 is a sectional view showing a conventional hot air supply device disclosed in, for example, Utility Model Publication No. 60-30659, in which 1 is the main body of the hot air supply device, and 2 is the interior of the main body 1 of the hot air supply device. 3 is a ventilation path for the air sent out from the blower 2; 4 is an electric heater that is installed in the ventilation path 3 and supplies heat to the air to make it hot air; 5 is a main body frame of the hot air supply device; , 6 is a cylindrical connecting pipe that communicates the ventilation path 3 with the opening 5A at one end of the hot air supply device main body 1, and 7 is a cylindrical connecting pipe that is slidable inside the connecting pipe 6, and has one end on the 5A side of the connecting pipe 6. A flexible stretchable hose to be inserted, 8 a stopper ring provided on the inner peripheral surface of the opening 5A side of the connecting pipe 6, and 9 a bag having an opening for storing and connecting the other end of the hose 7. It is made of mesh cloth or the like with appropriate breathability. 11 is a controller that manually adjusts the output of the electric heater 4 and is made of a casing separated from the hot air supply device main body 1; 12 is a recess in the main body frame 5 formed so that the controller 11 can be attached and detached; 13 is a concave portion of the controller 11; An output switching device 14 is provided in the main body 1 of the hot air supply device, which simultaneously switches the strength of the output of the blower 2 and the electric heater 4 in a stepwise manner by attaching and detaching the output. The adjustment dial 15 provided is a power switch provided at the upper part of the main body frame 5 in the drawing.

A conventional hot air supply device is configured as described above.
When the bag 9 is placed between the mattress A and the comforter B and the power switch 15 is turned on, the blower 2 and the electric heater 4 are energized, the blower 2 blows air into the air passage 3, and the air flow is generated by the electric heater 4. It receives heat and becomes warm air. This hot air flows through the connecting pipe 6 and the hose 7, flows into the bag 9, and flows out from almost the entire surface of the bag 9, thereby warming and drying the mattress A and the comforter B.

Furthermore, FIGS. 5 and 6 are, for example,
128059 is a perspective view showing a simple futon dryer shown in the publication, and a vertical cross-sectional view showing the usage state of the futon dryer, in which 101 is a futon; 103 is a futon dryer;
105 is a large number of air bags made of a soft plastic sheet with a large number of air outflow holes 102; an air supply bag communicating with one end of the air bag 103; 120 is a tongue piece provided at the outer end of the air bag 103;
1 is a fixture attached to this tongue piece 120. The dryer D is constituted by these.

How to use this dryer D will be explained.

As shown in Figure 6, two horizontal supports 12
2 and erect two pillars 123 perpendicular to pillar 1.
Futon frame 1 with a stand 124 placed horizontally on the upper end of 23
26, with the air supply bag 105 of the dryer D facing downward and the tongue piece 120 of the air bag 103 facing upward, place the fixture 1 on the stand 124 at the upper end of the futon frame 126.
21 to fix both sides of the air bag 103, and fold the dryer D into two. Then, the futon 101 is folded in two and placed on the folded dryer D, and hot air is sent into the air supply bag 105 from the air supply hose 107, and the hot air blown out from the air outflow small hole 102 is used. You can dry the Tsute Futon 101,
Alternatively, laundry or the like can be hung around the dryer D to dry it.

[Problem that the invention attempts to solve]

Conventional hot air supply devices and dryers such as those described above can warm and dry futons and blankets with warm air, and can kill dust mites living on futons and blankets. It is not suitable for heating and drying tatami mats, and has the problem of not being able to kill the mites that live inside the tatami mats.

This idea was made to solve this problem, and it warms not only the surface of the tatami but also the inside.
To obtain a hot air supply device capable of easily killing mites living in tatami mats by drying them.

[Means for solving problems]

The hot air supply device according to this invention has a ventilation sheet, and the ventilation sheet has a ventilation section made of mesh cloth or the like having appropriate ventilation, and the edges of the tatami mat are placed on two opposite sides of the ventilation sheet. A thin insert plate that is inserted into the gap formed in the section is fixed.

[Operation of the means to solve the problem] The ventilation sheet in this invention is made by inserting a board between the tatami and the sill or between the tatami and the sill, and creating a bag between the surface of the tatami and the ventilation part. Since the hot air can be used to heat and dry the tatami and even the futon placed on the ventilation sheet, it is possible to kill dust mites on the tatami and the futon.

〔Example〕

FIG. 1 is a diagram showing an embodiment of this invention.
Nos. 1 to 8 and 11 to 15 are exactly the same as the above-mentioned conventional device. Reference numeral 20 indicates a ventilation section 21 formed of mesh cloth or the like having appropriate breathability;
A plurality of thin insert plates 22 fixed to the end face of
and a hot air inlet 23.

The capacity of the electric heater 4 and the blower 2 are designed so that the temperature of the hot air is around 70°C.

In the hot air supply device configured as described above, as shown in FIG. 21 forms a bag-like opening in which the other end of the hose 7 is housed, and as shown in Figure 3, the other end of the hose 7 is housed in the opening at the top, a futon is placed on top of the vent, and the power source is Turn on the switch
Then, warm air of around 70℃ flows from the hose 7 to the ventilation section 2.
Air is blown out between the tatami and the tatami mat, and the ventilation section swells due to the wind pressure, effectively warming the tatami mat and even the futon.The tatami is heated not only from the surface, but also from the surface to the center of the tatami due to heat conduction. , resulting in high temperatures of 50° to 60°C.

Generally, dust mites are easily killed in an atmosphere of about 50 degrees Celsius or higher, so any living dust mites in futons or even tatami mats will die. Furthermore, both futons and tatami mats can be dried thoroughly.

〔Effect of the invention〕

As explained above, this idea consists of a ventilated sheet made of breathable vents, and a thin insert plate that is inserted into the gap formed at the edge of the tatami mat attached to two opposing sides of the ventilated sheet. With a simple structure, the tatami can be dried without shifting from the tatami, and the mites living inside the tatami can be killed.
Furthermore, if you cover the futon on top, you can dry the futon and tatami at the same time and kill dust mites.
