Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dryer for futons and the like (hereinafter referred to as a futon dryer), which has both a dust mite repelling function and a dust collecting function.

0002

[Technical Background] Futon dryers have the function of exterminating dust mites in addition to their original function of drying futons and the like. In such a futon dryer, for example, a bag-like body approximately the same size as the futon is interposed between the futon and the futon,
Hot air at a predetermined temperature is sent into the bag-like body from the main body of the dryer for a predetermined period of time, and the hot air is discharged through holes provided on the surface of the bag-like body to dry the futon and exterminate dust mites. In order to send this heated air, the dryer body has a built-in heater and fan. By the way, in the above-mentioned futon dryer, in order to prevent allergies, it is necessary to remove dead dust mites, feces, etc. after drying the futon (specifically, to clean the futon and the bag-like body with a vacuum cleaner, etc.). ) is recommended in the instruction manual, etc. However, since it is cumbersome to take out the vacuum cleaner and clean the futon after using the futon dryer, there is a strong tendency to neglect the cleaning, and dead dust mites, etc., are not removed sufficiently. There was a problem.

0003

OBJECT OF THE INVENTION The present invention was made to solve the above-mentioned problems, and it is possible to easily clean dead mites, feces, etc. without the need for a separate vacuum cleaner, and to keep the dryer clean when using it. To provide a futon dryer that does not give a feeling of discomfort or discomfort and can be operated in an actually clean state.

0004

[Summary of the Invention] In order to achieve the above object, the present invention provides a futon dryer with a dust collecting section for storing dead mites, etc., so that the futon dryer can also function as a vacuum cleaner by replacing the attachment after drying the futon. That's what I do. Therefore, according to this configuration, dead mites and the like can be cleaned without using a separate vacuum cleaner. Considering the possibility that the futon dryer of the present invention may be used as a vacuum cleaner on a daily basis, when drying the futon, the warm heat is sent out through the dust collecting section that contains dust other than the dust that accompanies the futon drying. The futon will be dried by air, so if the dust collection capacity of the filter is not very high (if it allows fine dust to pass through)
Not only is it actually unclean, but it can also make the user feel even more unclean. Since futon dryers are originally used to make futons clean and comfortable, this situation may be difficult for consumers to accept. Therefore, in the present invention, a bypass passage is provided in which the air sucked in from the suction port is sent out from the outlet without passing through the dust collecting section, and this bypass passage is used when drying the futon. According to this configuration, since the air that does not pass through the dust collecting section is sent to the futon, it is actually clean and does not make the user feel unclean.

[0005] Furthermore, since the dust collecting part can be made detachable during normal use and can be removed when drying the futon, the user can dry the futon with air that does not pass through the dust collecting part. It can also improve the usability. Further, the first flow path has hot air discharge holes on the surface and is branched in a network or dendritic form, and has dust suction holes on the surface and has a network or dendritic branch and the first flow path. By using an air mat-like drying/dust collection bag that includes a second flow path that is isolated from and intersects with the flow path, drying and cleaning can be performed at once without replacing attachments.

[0006] In the dryer of the present invention, a dehumidifying device can also be built into the dryer. This dehumidifying device is used to remove moisture from the air taken in from the suction port of the dryer, and there are two types of dehumidifying devices: one that uses a dehumidifying/heating method, and one that uses a dehumidifying agent such as silica gel or calcium carbonate. Ru. The bag-like body used in this case is not provided with a dust suction hole, and the air inlet (connected to the dryer's outlet) or air outlet (connected to the dryer's outlet) of the bag-like body is not provided. The air inlet (connected to the suction port) has a structure that can be sealed with an appropriate sealing means (zipper, cap, etc.). After drying the futon, the air inlet is tightly closed with a zipper, etc., and the bag is removed from the suction port of the dryer. After sucking out the air, by sealing the air outlet with a zipper or the like, the futon can be vacuum-packed in a clean and dry state.

[0007]

Embodiment An embodiment of the present invention will be described with reference to FIG. In the figure, 100 indicates the main body of the dryer, and due to the suction force of the fan 2 driven by the motor 1, surrounding air is sucked in through the suction port 3 and blown out from the outlet port 4. During this time, the air is 5, the air is heated to a predetermined temperature. The switching valves 6 and 7 are located on the a side and the b side in the figure to switch the passage and selectively guide the air sucked in from the suction port 3 to the bypass passage 8 or the dust collection section 9. Dust sucked in through the suction port 3 is captured by the filter 10, and clean air is blown out from the outlet 4. As this cleaning filter 10, various filters used in vacuum cleaners can also be used.

Next, the operation of the dryer main body 100 constructed as described above will be explained. First, when drying a futon, the bag-like body 12 having a porous hole H1 for drying the futon is attached to the outlet 4 via the hose 11, and the switching valves 6 and 7 are operated to the side a. The bag-like body 12 can be the same as that attached to a conventional futon dryer. Air is sucked in from the suction port 3 in the direction shown by arrow F1. Here, since the switching valves 6 and 7 are located on the a side, the air passes through the bypass passage 8 from the suction port 3, is heated by the heater 5, and flows from the outlet port 4 to the direction indicated by the arrow F.
It is sent out as heated air in two directions. This hot air is sent to the bag-like body 12 via the hose 11, and the hole H1
The futon is heated by blowing air outwards. By continuing to heat the futon for an appropriate period of time, the moisture in the futon is removed, and living organisms such as mites living inside the futon crawl out to the surface of the futon, and some of them die on the surface.

[0009] After the futon is dried, connect the hose 1 from the outlet 4.
1 and the bag-like body 12 are removed, and an attachment (not shown) such as a vacuum cleaner hose (usually a T-shaped suction tool with a brush) is attached to the suction port 3. In addition, the switching valves 6 and 7 are
side, and switch the air passage to the dust collecting section 9 side. Then, the futon, the bag-like body 12, etc. are cleaned using the attachment. In this case, the power to the heater 5 is turned off. Dead mites and dust sucked in from the suction port 3 are collected in the dust collection section 9.
The dead mites and the like remain in the filter 10, and only clean air is sent out from the outlet 4. Therefore,
According to this embodiment, without using a separate vacuum cleaner,
After the futon has been dried, dead mites attached to the surface of the futon and the bag-like body 12 can be cleaned, and when the futon is drying, the dust collection section 9 is sealed by the switching valves 6 and 7, which is sanitary and convenient for the user. It will not make you feel unclean. Although the operating mechanism of the switching valves 6 and 7 will not be described in detail, either a manual mechanism or an electromagnetic mechanism may be employed. Further, in the above embodiment, when the dryer 100 is used for drying futons and when used for cleaning, the arrow F1 is
, F2, but by changing the rotation direction of the fan 2, air can be flowed in the opposite direction to the arrows F1 and F2 to dry or clean the futon ( Note that when the futon dryer is used as a vacuum cleaner, the filter 10 needs to be shaped so that it can capture dust and be attached to the dust collector 9 in accordance with the direction of air flow.

FIG. 2 shows an embodiment of a dryer using a dust cassette 21 instead of the filter 10. In the dryer main body 200 shown in the figure, the housing of the dust cassette 21 is molded from plastic, and the housing is provided with openings 22 and 23. Inside the dust cassette 21, the filter 10 shown in FIG. 1 is provided, although not shown. Further, in this embodiment, both futon drying and cleaning can be performed without providing the switching valves 6 and 7 of FIG. 1. When using the dryer main body 200 as a futon dryer, the dust cassette 21 is removed from the main body 200. Note that the opening 23
For hygiene reasons, it is preferable to provide the dust cassette 21 with, for example, a spring-loaded sliding lid (not shown) so that the removed dust cassette 21 is automatically sealed. After the futon has been dried, when operating the dryer as a vacuum cleaner, the dust cassette 21 is attached to the dryer main body 200. At this time, the sliding lid of the opening 23 may be provided with a claw, for example, so that the claw catches on a part of the dryer main body 200 and the lid is automatically opened. Dead mites, dust, etc. sucked in through the suction port 3 enter the filter 9 through the opening 23, and only clean air is sent out from the opening 22 to the outside of the dust cassette 21. According to this embodiment, the main body 20
When the 0 is used as a dryer, the dust cassette 21 is taken out to the outside, so it has a structure as a normal dryer. Therefore, even when used also as a vacuum cleaner, cleanliness can be ensured and the user's impression of uncleanliness is reduced compared to the above-described embodiments.

Furthermore, as shown in Figure 3, the air passage when used as a vacuum cleaner and the air passage when used as a dryer are completely separate, further improving cleanliness. You can also do it. Dryer main body 30 in the same figure
0, the fans 2 and 2' are provided in the air passage when used as a dryer and in the air passage when used as a vacuum cleaner, respectively, and when used as a dryer, the air flows in the direction of arrow F2'. When used as a vacuum cleaner, air is sucked in from the direction of the arrow F1, heated by the heater 5, and blown out in the direction of F2.
It is ejected in the direction of F2. In the embodiment shown in FIG. 3, a dust cassette 21 is used as in the embodiment shown in FIG. Also,
Although not shown, the connection between the motor 1 and the fans 2, 2' can be switched by gears, etc., so that both can be rotated at the same time, or when one fan rotates, the other fan can be stopped. .

In the above embodiment, the dryer main body 100, 2
First, attach a dryer attachment (hose 11, bag 12) to 00 or 300 and use it as a dryer.
Thereafter, the attachments 11 and 12 are removed and a vacuum cleaner attachment is attached to use the vacuum cleaner. For this reason, it is necessary to replace the attachment each time the futon is dried or cleaned, which may be somewhat troublesome for the user. FIG. 4 shows an example of a bag-like body (drying/dust collection bag) that eliminates this complexity. In FIG. 4, the bag-like body 12' is configured in the shape of an air mat, and the first flow path (thermal air duct 30) is
- It becomes a path for hot air from the dryer main body 100, 200 or 300 in FIG. This air duct 30 is provided in a network-like or dendritic-like branching manner. In FIG. 4, a plurality of hollow passages extend in parallel at predetermined intervals inside the bag-like body 12'. The communication duct 31 constitutes a communication path for each air duct 30. Bag-like body 12 in FIG.
' has a double structure, and the space between the air duct 30 (or the communication duct 31) and the outer material 33 forms a second flow path (dust flow path 32). Like the air duct 30, the dust flow path 32 is branched into a network or dendritic structure. The air duct 30 (or the communication duct 3
1) and the dust flow path 32 are isolated, and the air duct 3
0 has a large number of exhaust holes H1 through the outer material 33, and a dust flow path 3.
Similarly, a large number of suction holes H2 are provided on the outer material 33 side of No. 2. Although not shown, the bag-like body 12'
is provided with a pair of hoses, one hose communicating with the air duct 30 and the communication duct 31, and the other hose communicating with the dust flow path 32. Note that the configuration of the air duct 30 and dust passage 32 of the bag-like body 12' is not limited to the configuration shown in FIG. 4, but may be as shown in FIG. 5, for example.

Next, the function of this bag-shaped body 12' will be explained. This bag-like body 12' is the main body 10 of the dryer shown in FIG.
Used in combination with 0,200 or 300. A hose (not shown) leading to the hot air duct 30 is attached to the outlet 4 of FIGS. 1-3, and a hose (also not shown) leading to the dust flow path 32 is attached to the suction port 3 of FIGS. 1-3. For example, in FIG. 1, the main body 100 is operated as a dryer with the switching valves 6 and 7 located on the a side, and the outlet port 4 is operated as a dryer.
From there, heated air flows into the heated air duct 30 in the direction of arrow G1 in FIG. Then, hot air is blown out in the direction shown by arrow G2 through the outer fabric 33 covering the hot air duct 30, thereby heating the futon and the like in contact with the bag-like body 12'. As a result, the futon, etc. dries, but at the same time, living organisms such as mites living in the futon, etc. are expelled to the surface of the futon (especially near the unheated holes H2), and some of them die. After a predetermined period of time has elapsed, the switching valves 6 and 7 shown in FIG. 1 are moved to the b side to operate as a vacuum cleaner. In this case, mites (including both living ones and dead ones) pass through the mat surface material 33 and are guided to the dust flow path 32 as shown by arrow G3, and are carried in the direction of arrow G4. The mites are eventually housed within the filter 10 of FIG. 1, for example. Note that switching from operation as a dryer to operation as a vacuum cleaner can also be performed using a timer. In addition, when using the dryer shown in Figure 2 or Figure 3,
It can also function as a dryer and a vacuum cleaner at the same time. In this case, in FIG.
, 2' are driven simultaneously. When the drying operation and the cleaning operation are performed at the same time, living things such as mites are easily guided to the hole H2 in an attempt to escape from the hot air blown out from the hole H1, so it is possible to capture the mites with a high probability. can. According to the embodiments shown in FIGS. 4 and 5, the dryer main body (
100, 200 or 300), it is possible to continuously dry futons, catch mites, or clean mite carcasses without changing the attachment. Further, for example, the bag-like body 12' can be washed completely or by pouring tap water or the like into the dust passage 32. In this case, for example, if a hose leading to the dust passage 32 is attached to the outlet 4 and heated air is sent into the dust passage 32, the bag-shaped body 12
′ becomes easier to dry. In each of the embodiments shown in FIGS. 1 to 3, the main body of the dryer is described as being of a portable type, but the main body of the dryer may be installed outdoors and the hose may be brought into the room for drying and cleaning. can.

Next, an embodiment of a futon dryer with a built-in dehumidifying device will be described with reference to FIG. In this embodiment, a bag without pores (indicated by 12'' in the figure) is used as the bag.This bag 12'' has an air outlet (
The air suction port 13 (connected to the suction port 3 of the dryer) or the air suction port 14 (connected to the discharge port 4 of the dryer) can be sealed with an appropriate sealing means (such as a zipper or a cap). In the figure, a zipper (not shown) is opened and a futon 16 placed on a tray 15 having a ventilation section 15' is shown.
is placed into the bag-like body 12'' together with the cage 15.Then, the zipper is closed, hot air is forced into the bag-like body 12'' through the air intake port 14, and air is sucked through the air outlet 13. At this time, make sure that the air pressure in the closet is greater than the suction air pressure. As a result, the bag-like body 12
'' can be maintained in an expanded state.Futon 16
After removing dead mites, etc., and removing moisture with a dehumidifier, open the zipper, take out only the screen 15, seal the air intake port 14 with a cap, etc., and suck the air inside the bag-like body 12''. After the futon 16 is vacuum-packed with the bag-like body 12'', the air inlet 14 is tightly plugged. In this way, the futon can be vacuum packed in a clean and dry state.

[0015]

[Effects of the Invention] As detailed above, according to the present invention,
It is possible to easily clean the dead mites after the futon has been dried without preparing a separate vacuum cleaner. In addition, if the dryer is also used as a vacuum cleaner, which may impede hygiene and cause a feeling of uncleanness or discomfort to the user, the hot air can be sent out without going through the dust collection part. Hygiene can be ensured and the sense of cleanliness is not compromised.
