Description

Equipment for drying and disinfecting bedding and clothing

The present invention relates to a dry disinfection device that kills, removes, disinfects, and dries bedding and clothing pests.

Conventionally, a compression bag having an insect repellent effect has been proposed for compressing and preserving futons and clothes so as not to be bulky (see, for example, Patent Document 1).
Further, as a futon dryer for removing moisture from futons and clothes, a futon dryer having an insecticidal function has been proposed (see Patent Document 2, for example).

The air blower 16 is composed of a reversible flow fan (hereinafter simply referred to as "fan") 16a arranged in the flow path 19 and a motor 16b for driving the fan 16a. By rotating the fan 16a forward, the air inside the bag body 3 is sucked up to a vacuum state through the connection pipe 5a and taken into the main body 5, and the taken-in air is discharged from the flow path 19 through the duct 21 to the outside. can be discharged. Further, by rotating the fan 16a in reverse, the air outside the main body 5 can be taken in from the intake port 20, passed through the branch path 19a and the flow path 19 in order, and injected into the bag body 3 via the connection pipe 5a. The air blower 16 can change the rotational speed of the fan 16a based on instructions from the controller 11 to adjust the amount of air to be injected, the amount of suction, and the speed.

The heater section 17 is composed of a heater 17a for heating the air taken in from the intake port 20 and a negative ion generator 17b for supplying negative ions to the air. The heater 17a has the ability to heat the air in the flow path 19 to about 140° C., and the controller 11 detects the temperature (room temperature) of the air taken in from the intake port 20 by means of the temperature sensor 33 of the branch path 19a. Calculation is performed, and the controller 11 issues a command to the heater unit 17 to adjust the amount of heat emitted by the heater 17a to determine an appropriate heating temperature at any time.

The display unit 15 displays the currently selected mode, the current state ("sucking", "injecting high temperature air", "injecting room temperature air", "remaining time", "mite extermination mode", "mite extermination/ A display 26 (see FIG. 2) that displays various information such as the number of repetitions of suction and injection, temperature, humidity, etc., and a speaker (not shown). consists of

The operation unit 14 consists of a button group 27 (see FIG. 2) for the user to operate the main body 5. The button group 27 specifically includes a power button, a mode selection button, a button for setting the number of repetitions of suction and injection, a temperature setting button, an operation start button, an operation stop button, a timer setting button, a suction button, an injection button, and the like. consists of

The motor-operated valve 18 is a slide-type valve mechanism capable of opening and closing the passage 19 of the main body 5 in stages such as full opening (open), half opening, 1/3 opening, 1/5 opening, 1/10 opening, closing, etc. It is composed of a valve 18a made of heat-resistant rubber arranged in the flow path 19 and a motor 18b for driving the valve 18a.

Regarding the electric valve 18, when the main body 5 sucks the air in the bag body 3 and discharges it to the outside, the flow rate of the air in the flow path 19 is large, so the control unit 11 controls the motor 18b to fully open the valve 18a. Then, it is gradually closed to increase the degree of vacuum in the bag body 3, and when the inside of the bag body 3 is in a vacuum state, the valve 18a is closed. When the main body 5 injects air into the bag 3, the control unit 11 controls the motor 18b to open the valve 18a a little, so that the outside air is taken into the main body 5 and heated. (for example, 110° C.) is injected into the bag 3 . This is because when external air is taken in with the valve 18a fully open, a force to take in air acts on the bag body 3, which is in a vacuum state, and a large amount of the external air passes through the main body 5 and into the bag body. This is because the air at the target temperature cannot be properly injected into the bag body 3 because the air enters the inside of the bag body 3 . It should be noted that the valve 18a can change the degree of opening based on an instruction from the control unit 11 to adjust the suction amount, speed, and injection amount of air. It is not limited to the electric valve 18 described above, and a valve mechanism that performs a similar role may be employed.

In the drying and disinfecting apparatus 1 configured as described above, the control unit 11 drives the motor 18b of the electric valve 18 to control the valve 18a, and drives the motor 16b of the air blowing unit 16 to rotate the fan 16a forward. As a result, the air in the bag 3 and the air contained in the object 2 in the bag 3 are sucked into the main body 5 through the

connection pipes

3a and 5a, and are discharged outside through the duct 21 through the flow path 19. Then, the inside of the bag body 3 can be brought into a vacuum state, and then high temperature air such as 110° C. is injected into the bag body 3 . After a certain period of time has passed, the air inside the bag 3 is strongly sucked again, and the air inside the bag 3 is removed along with insects (for example, mites) hidden on the surface or inside the object 2, as well as insect feces and corpses. , dust, pollen, odors, etc. can be discharged outside from the duct 21 via the inside of the main body 5. - 特許庁The vacuum state is a state in which the air inside the bag 3 and the air contained in the object 2 inside the bag 3 are discharged to the outside of the bag 3 and the object 2 is strongly compressed.

In the drying and disinfecting apparatus 1, the control unit 11 constantly grasps the temperature (room temperature) of the air taken in from the air inlet 20 by the temperature sensor 33 of the branch passage 19a, and performs precise calculations. to control the opening and closing degree of the valve, raise the heater 17a to a high temperature so that the air at the target temperature can be injected, and operate the negative ion generator 17b, while driving the motor 16b of the blower 16. Reverse the fan 16a. Note that the control unit 11 also causes the fan 16a to have an appropriate number of revolutions. As a result, indoor air is taken into the main body 5 from the intake port 20, heated to a predetermined temperature (for example, about 50 to 110° C.) by the heater unit 17 in the flow path 19, and negative ions are generated by the negative ion generator 17b. is supplied and injected into the bag body 3 through the

connection pipes

5a and 3a. Specifically, only high-temperature air is injected into the bag body 3, which is maintained in a vacuum state, and the bag body 3 can be filled in several seconds to several tens of seconds. As a result, the bag 3 can be filled with high-temperature air to the depths and edges of the object 2, which dries the object 2 and kills insect pests lurking on the surface and inside of the object 2. Viruses can be killed or inactivated (disinfected). This effect is enhanced by maintaining the state in which the bag 3 is filled with high-temperature air for a predetermined time (for example, several tens of seconds to several minutes).

For example, since live mites cling to the fibers of the object 2, they cannot be easily removed even if they are washed with a washing machine or sucked with a special vacuum cleaner that has excellent mites removal capability. .
On the other hand, the dry disinfection apparatus 1 repeats the above-described discharge of the air in the bag 3 and supply of high-temperature air into the bag 3 a plurality of times as necessary, thereby removing insects from the object 2. removal of feces and corpses, dust, pollen, various allergens, odors, etc., destruction and inactivation (disinfection) of molds, bacteria and viruses, and drying can be performed more efficiently and easily in a short time. In addition, the object 2 such as bedding and clothing can be made soft and warm in a short period of time. The predetermined temperature and the predetermined time of the high-temperature air are set by the user in consideration of the heat resistance of the target object 2, etc. is preferred.

In addition, in the dry disinfection apparatus 1, dead insects, sterilized or inactivated bacteria, viruses, and molds are removed by the supply of high-temperature air into the bag 3, and dust, pollen, and allergies are removed by discharging the air in the bag 3. It can be discharged directly to the outside through the duct 21 together with substances, moisture, odors and the like. Therefore, it is possible to prevent these substances from being left behind in the room and adversely affecting the human body. You can also prevent it from slipping.
In addition, since the dry disinfection apparatus 1 can supply negative ions to the object 2 by the negative ion generator 17b, it can be expected to improve the health of the user.

In the dry disinfection apparatus 1, the control unit 11 always monitors the temperature sensor 24 and the pressure sensor 23 for safety management. , the effect is displayed on the display 26 and output by the speaker, and the safety function mounted on the main body 5 quickly lowers the temperature and pressure to the normal level. With this configuration, the safety of the dry disinfection device 1 can always be ensured.

The dry disinfection apparatus 1 according to this embodiment can execute four modes, ie, a manual mode, an automatic mode, a cooling mode, and a drying mode, which will be described below.
Common to the four modes, the user stores the object 2 in a bag 3 having a size suitable for the size of the object 2 in advance, closes the

fasteners

7, 7 with the slider 8, and connects the bag 3 to the connecting pipe. 3a and the connection pipe 5a of the main body 5 are connected. In addition, the user lays an underlay plate 4 of a size suitable for the size of the bag body 3 under the bag body 3, fixes the duct 21 of the main body 5 to, for example, a ventilation fan 28 with a fixing member 21a, and secures the tip of the duct 21. It is arranged near the ventilation fan 28. - 特許庁1 and 2 show a normal ventilating fan as the ventilating fan 28, the ventilating fan is not limited to this, and a range hood type ventilating fan may be used.

(A-1) When the user presses the suction button, the controller 11 controls each part of the main body 5, and the main body 5 sucks air from the bag 3 and discharges it from the duct 21. This suction operation is performed while the user is pressing the suction button and is stopped when the user releases the suction button. Also, the suction operation is automatically stopped when the bag body 3 is in a vacuum state. Specifically, the control unit 11 stops the suction operation of the main body 5 when the pressure sensor 23 of the flow path 19 detects that the pressure of the flow path 19 has become equal to or less than the first predetermined value. The first predetermined value is the pressure value of the flow path 19 when the bag body 3 is in a vacuum state, and is stored in the storage unit 12 in advance.

(A-2) When the user presses the injection button, the controller 11 controls each part of the main body 5, heats the air taken in by the main body 5 from the intake port 20 to a predetermined temperature with the heater 17a, and generates the negative ion generator 17b. gives negative ions and injects them into the bag body 3. This injection action is performed while the user is pressing the injection button and is stopped when the user releases the injection button. Also, the injection operation is automatically stopped when an appropriate amount of air has been injected into the bag 3 . Specifically, when the pressure sensor 23 of the channel 19 detects that the pressure of the channel 19 has reached the second predetermined value, the controller 11 stops the injection operation of the main body 5 . The second predetermined value is the pressure value of the flow path 19 when the bag 3 is filled with an appropriate amount of air, and is stored in the storage unit 12 in advance.

(A-3) The control unit 11 causes the display to display the elapsed time from the end of the injection operation in (A-2) while the high-temperature air is being injected into the bag body 3 . After a predetermined period of time has elapsed, the control unit 11 causes the display to indicate that the pest killing, removal, disinfection, and drying of the target object 2 have been completed, and output to the speaker.
Note that the user repeats the above (A-1) to (A-3) as necessary in consideration of the state of the object 2 and the like.

Specifically, the control unit 11 stops the suction operation of the main body 5 when the pressure sensor 23 of the flow path 19 detects that the pressure of the flow path 19 has become equal to or lower than the third predetermined value. The third predetermined value is the pressure value of the channel 19 when the bag body 3 is in a semi-vacuum state, and is stored in the storage unit 12 in advance. A semi-vacuum state refers to a state in which the degree of vacuum is lower than the vacuum state described above. In this (D-1), if the suction operation is performed until a vacuum state is achieved as in the other modes, not only the air in the bag 3 but also the water adhering to the object 2 is directly sucked. This is to prevent dust from entering the main body 5 and causing a failure.

With the four modes described above, the dry disinfection apparatus 1 manually or automatically kills and removes pests from the object 2, disinfects and dries the object 2, cools the object 2 that has been heated to high temperature, and dries the object 2 that is wet. be able to.

The drying and disinfecting apparatus 1 is not limited to bedding and clothes, but can also be used as the object 2 such as cushions, cushions, carpets, curtains, etc. for drying, killing and removing pests, etc., and disinfecting. It suppresses the onset of respiratory diseases such as asthma and bronchitis, allergic rhinitis, conjunctivitis, dermatitis, etc., leads people and pets already suffering from these symptoms to remission, and helps maintain and improve the health of humans and animals. be able to contribute.

It is preferable that the user can freely select the length of the duct 21 of the main body 5 in accordance with the usage environment when purchasing the dry disinfection device 1 . This makes it possible to easily fix the tip of the duct 21 to, for example, a ventilation fan with the fixing member 21a or to expose it through a window. In addition, air containing mites, mites' feces and carcasses, dust, pollen, odors, mold, bacteria, viruses, etc. sucked from the bag 3, and high-temperature air can be discharged directly to the outside to keep the indoor air clean. can be kept in

The drying and disinfecting device 1 can significantly shorten the operating time compared to conventional futon dryers, so energy saving and reliable disinfection can be achieved.

As of 2015, it is said that about 29 million people in Japan suffer from allergic symptoms caused by dust mites. According to the information on the website of the Ministry of Health, Labor and Welfare, as of 2011, half of the population had some kind of allergy. It is said that an overwhelming number of people have allergies to dust and pollen, and bedding and clothes are in contact with the human body for a long time every day. expected to be effective.
Allergens that may cause anaphylactic shock and the novel coronavirus that is spreading all over the world are removed by the dry disinfection device 1 and discharged to the outside without leaving them indoors. can. In particular, the new coronavirus can be killed by heating at "100 ° C for 5 minutes" according to the website of Nippon Medical Shinposha, and "80 ° C for 10 minutes" according to the website of the Ministry of Health, Labor and Welfare. Also in this respect, the use of the dry disinfection apparatus 1 brings about a very large effect.

General conventional futon dryers that continuously supply hot air by inserting a nozzle between the futon or mattress and the quilt are effective in exterminating and inactivating harmful substances such as mites, mold, pollen, bacteria, and viruses. takes a long time or is not feasible. Furthermore, since the hot air, humidity, and various harmful substances drift in the room, air pollution, rise in room temperature, and rise in humidity cannot be avoided, which causes health hazards to humans and animals, and adverse effects on electronic devices, etc. There is a risk.
On the other hand, the drying and disinfecting apparatus 1 can reliably discharge the air containing harmful substances sucked from the bag 3 in a short period of time to the outside through the ventilation fan or the window as described above. Further, since the configuration is such that high-temperature air is injected into the bag body 3 in a vacuum state, it takes only several seconds to several tens of seconds to inject the high-temperature air. Since all the high-temperature air is stored in the bag 3, indoor air pollution, room temperature rise and humidity rise can be avoided. can be secured and maintained.

The dry disinfection device 1 has a simple configuration and can be manufactured at low cost in a small size and light weight. For this reason, it can be sold at a low price, and global spread can be greatly expected. In addition, since the dry disinfection apparatus 1 has a simple structure, it is less likely to break down, and the cost of repairs in the event of a breakdown can be reduced.

As described above, according to the present embodiment, the object 2 such as bedding and clothing can be effectively killed, removed, disinfected, and dried in a short period of time while preventing an increase in indoor temperature and humidity and air pollution. It is possible to realize the dry disinfection device 1 that can be used. Therefore, the user can continue to use the object 2 in an extremely hygienic condition with the dry disinfection device 1, and can compress and store the object 2 in the bag 3 in an extremely hygienic condition.

Furthermore, the drying and disinfecting apparatus 1 may be configured to include a fan such as a turbo fan that is capable of sucking air in one direction (hereinafter referred to as a "normal fan") instead of the reversible flow fan 16a (this configuration is referred to as another configuration). Of course, a normal fan should have sufficient heat resistance.

In another configuration, the control unit 11 opens the slide-type electric valve 18 and rotates the normal fan forward. As a result, the air in the bag 3 is sucked into the main body 5 via the

connection pipes

3a and 5a, and is discharged to the outside from the duct 21 through the flow path 19. 3 can be evacuated. Next, the controller 11 once closes the electric valve 18, stops the normal fan, and activates the heater 17a and the negative ion generator 17b. When the electric valve 18 is opened, the bag body 3, which has been compressed in a vacuum state, sucks in air and tries to restore its original state. That is, the bag body 3 takes only the high-temperature air in the flow path 19, which is taken in from the intake port 20 of the main body 5, heated by the heater section 17, and given negative ions by the negative ion generator 17b, through the

connection pipes

3a and 5a. through which a certain amount of hot air injection into the bag 3 is achieved. Therefore, by using a normal fan, an effect similar to that obtained by using the reversible flow fan 16a can be obtained.

Also, in another configuration, each valve is a slide-type valve mechanism with sufficient heat resistance, and the flow path 19 is opened (fully opened), half-opened, 1/3-opened, 1/5-opened, 1/10-opened. It has a specification that can be closed in stages such as opening, closing, etc. When sucking the air in the bag body 3, the control unit 11 fully opens the electric valve 18 and rotates the normal fan forward to start sucking. do. Next, the control unit 11 monitors the pressure of the air in the bag 3 from the output of the pressure sensor 23 in the flow path 19, and gradually reduces the degree of opening of the flow path 19 with the motor-operated valve 18. Since the suction force can be increased stepwise, the suction time required to create a vacuum state or a semi-vacuum state can be shortened.
On the other hand, when high-temperature air is injected into the bag body 3, if the temperature of the indoor air taken into the flow path 19 from the intake port 20 of the main body 5 is high, the heater 17a is set at a predetermined temperature (for example, 50 to 110°C). ) in a short time, the controller 11 opens the motor-operated valve 18 to ⅓ or the like. When the temperature of the room air taken into the flow path 19 from the intake port 20 is low, it takes time to heat the room air to a predetermined temperature by the heater 17a. /10, etc. As a result, even when the temperature of the indoor air is low, high-temperature air having reached the target temperature can be injected into the bag body 3 .

All of the members described above have heat resistance that can withstand high temperatures of 150°C or higher, and each part of the main body 5 functions normally even at high temperatures of 200°C.

The above-mentioned "vacuum state (first predetermined value)" is the same as the pressure value that can be achieved using a high-performance compression bag for futons and clothes that are widely available on the market and a household vacuum cleaner. "Semi-vacuum state (third predetermined value)" is a degree of vacuum that is 1/3 of the vacuum state, and the second predetermined value is equal to or greater than the pressure value at the time of starting suction from the compression bag. This is the pressure value at which (appropriate amount) of air is contained in the bag body 3 .

The above-described "appropriate adjustment of the opening/closing degree of the valve, the heating degree of the heater 17a, and the rotation speed of the fan 16a" by the control unit 11 is always carried out during the operation of each of the above-mentioned modes, and any purpose can be accurately achieved. achievable.
