[Industrial applications]

 The present invention relates to an underfloor dehumidification / ventilation device for dehumidifying and ventilating air under a building floor by using exhaust air from a cleaner body in a central cleaner, thereby preventing termites from being generated.

[0002]

[Prior art]

 Generally, as a method for repelling termites, a pesticide for organophosphorus pesticides is often sprayed under the floor, and it is left to a specialist. However, this pesticide may cause poisoning symptoms such as coughing, nausea, diarrhea, and headache, and is serious only for air pollution that persists for a long time. In addition, recently, there are an increasing number of cases where exhaust fans are attached to several underfloor ventilation openings per house for the purpose of controlling termites and removing moisture under the floor. As a result, air containing pesticides is released to the outside, and the neighbors rather than the termite-controlled house will be harmed. By the way, the following measures can be taken as measures against termites that replace pesticides. As a base material, hinoki, hiba, larch, and other heart-preserving materials with excellent decay resistance are used. Apply wood vinegar (a vinegar that is a by-product of charcoal burning and is used by organic farmers in place of pesticides) as a basis. This is applied not only at the time of construction, but also once a year on the base around the base. Install a central cleaner to exhaust underfloor. Exhaust for a certain period of time every day keeps the underfloor dry. In addition, recently, there is also provided an automatic ventilation means for detecting the humidity under the floor and controlling the start and stop of the intake fan and the exhaust fan by a computer.

Although the above-mentioned means and the means in combination with or are preferable, the implementation thereof must be entrusted to a professional company and is not easily performed by the resident. However, the above-mentioned means does not only reduce the damage of termites by itself, but also makes it easy to apply them to existing structures, and allows residents to perform ventilation operations. It has the advantage that it does not have to be done.

By the way, in the central cleaner, suction panels (inlets) are arranged at respective required places such as each room or passage of a building, and a plug plug provided at the hose end of the dust suction tool is installed. Although the cleaner is started and stopped by fitting and operating the switch, the cleaner is installed either below the floor of the building or inside or outside the floor. However, in the latter case, it is impossible to ventilate under the floor.

Further, the automatic ventilation means 60, as described in detail in FIG. 6, includes a specific ventilation opening 43 a among a plurality of ventilation openings 43 arranged at required locations on the underfloor side wall 42 of the building 40. The outside air is sucked into the underfloor 41 by the intake fan 61 installed in the above and is installed in the other specific ventilation port 43b through the partition wall ventilation hole 45 that communicates several sections 46 divided by the underfloor partition wall 44, respectively. The exhaust fan 62 is configured to exhaust the air to the outside, and these fans 61 and 62 are automatically activated when the humidity sensor 63 arranged at an appropriate location detects that the humidity exceeds a predetermined humidity. It is set to stop. The ventilation openings 43c other than the specific ventilation openings 43a and 43b are closed so that a constant air passage is formed under the floor 41. Further, an air purifier 64 may be additionally installed in front of the intake fan 61.

[Problems to be solved by the device]

 However, in the central cleaner of the above means, even when a vacuum cleaner is installed under the floor, there is no idea to utilize the exhaust gas for the underfloor ventilation, and it happens to have a ventilation function. Therefore, the exhaust gas ejected from the exhaust port of the vacuum cleaner body only raises dust on the ground due to the rapid wind force, and it does not provide efficient ventilation under the floor. Moreover, since the automatic ventilation means of 1 sucks and discharges outside air under the floor, it introduces high-humidity air in the rainy season or the rainy season, which rather increases the humidity under the floor. In addition, it requires a permanent electricity usage fee, and the initial cost of equipment is extremely expensive.

The present invention has been made in view of the above circumstances and does not require a special operation by a resident, and discharges the by-product exhaust from the cleaner to the upper part of the floor under the operation of the cleaning work. Underfloor dehumidification ventilation that can naturally and efficiently dehumidify and ventilate the underfloor air without causing dust on the ground to prevent the occurrence of termites, and can be easily applied to existing buildings. The purpose is to obtain the device.

[Action]

 In the underfloor dehumidifying ventilation device of the present invention, when a resident uses a central cleaner having a vacuum cleaner body installed under the floor to clean the room indoors, the indoor air sucked by the dust suction device is After being filtered by, it is discharged from its exhaust port, reaches the exhaust diffusion diffuser through the exhaust pipe, and is dispersed to weaken the wind force. And, it is discharged in the height direction above the horizontal plane, that is, toward the upper part under the floor, and then is discharged to the outside from the ventilation hole of the side wall of the base through the partition ventilation hole. At this time, the clean indoor air dried by the air conditioner is warmed to some extent by passing through the dust collection and suction pipes and the dust bag, but the motor and exhaust fan of the vacuum cleaner further raise the temperature and dry it. Since it is in a state, underfloor materials are heated to dehumidify and ventilate the underfloor air to prevent the occurrence of termites. When a jet pump is installed in the exhaust system, the circulation of air in the compartment in which it is installed is promoted, so that the efficiency of ventilation is significantly improved. In addition, although the efficiency of ventilation decreases slightly, even if an exhaust diffusion emitter is directly attached to the exhaust port of the vacuum cleaner body without using an exhaust pipe, dust on the ground will rise to the underfloor air. The effect of dehumidification ventilation can be given without.

The main components are a wiring (not shown) provided along with the dust collection suction tool 56 detachably connected to the suction panel 57.

As shown in FIG. 3, the cleaner body 51 is formed by partitioning a dust collection chamber 52 and a power chamber 53 by a partition wall 54. The dust collecting chamber 52 has a dust collecting cylinder 52a into which the end of the dust collecting and sucking pipe 58 is fitted and which penetrates the end surface, and has a built-in special paper collecting bag 55 connected to the dust collecting cylinder 52a. It Further, an opening / closing lid 52b for replacing the dust collecting bag 55 is provided on the upper surface, and a secondary filter 52c for exhausting air sucked into the power chamber 53 can be attached to the partition wall 54 side. . The dust collecting bag 55 is a paper bag formed by providing a dust suction port 55a that is fitted to the inner end of the dust suction cylinder 52a that projects and is fixed to the inner surface of the dust collecting chamber 52. It has a double structure and can filter up to 99% of fine dust, mites, and allergic bronchitis source dust, creating a very hygienic and comfortable environment for environmental hygiene, which can be applied to clean room systems. It is an American product with ultra-high performance and international patents. The bottom paper of the two-layer manufacturing method uses the vibration during suction to eliminate the clogging of fine particles, so the filtration function is permanent. Next, the power chamber 53 is internally provided with a motor 53a for passing the further cleaned exhaust gas through the secondary filter 52c, and an exhaust fan 53b combined with the motor 53a. 53c is provided.

Therefore, a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. The underfloor dehumidification / ventilation apparatus 1 of this embodiment has a rear end of an exhaust pipe 30 connected to the exhaust port 53c. The exhaust diffusion emitter 10 is connected to the. As shown in FIG. 2, the exhaust diffusion emitter 10 is formed in a substantially cubic box body, has an inlet 11 on one end plate 10d, and has an emission slot 1 on the front face 10a. 2 is opened over the entire length, and the edge of the bottom plate 10b forming the discharge elongated hole 12 is a curved portion 10c which is warped upward. In addition, a plurality of partition plates 13 are radially arranged between the inlet 11 and the elongate hole 12 in order to evenly discharge the exhaust gas that has been sent into the box body. It is installed. A rotatable wind direction control plate 15 that can set the discharge direction of the exhaust gas is connected to the tip of the partition plate 13 that faces the discharge elongated hole 12.

If the room air dried by an air conditioner is warmed by passing through the dust collection suction pipe 58 and the special dust collection bag 55, it becomes clean room or aseptic room air. Be cleaned. Then, the degree of cleanliness is further increased through the secondary filter 52c and passes through the motor 53a and the exhaust fan 53b at about 20,000 rpm, and when passing, the air is decomposed to generate a re-dried state and a heat source (35 to 40 ° C). Then, it is ejected and sent into the exhaust pipe 30. This powerful exhaust diffuses by the exhaust diffusion emitter 10 to weaken the wind force, and is emitted from the emission slot 12 in the height direction above the horizontal plane, so that dust on the ground inside the underfloor 41 rises. It is filled without being filled, and is expelled to the outside from the ventilation opening 43 of the underfloor side wall 42 through the partition ventilation hole 45. Therefore, the air in the underfloor 41 replaces dry and clean air to prevent the generation of termites. In particular, the air supplied to the underfloor 41 is indoor air, which is completely different from the type that introduces outside air, so there is no effect even in the case of high humidity during rainy weather or rainy season. is there. The operation for dehumidifying and ventilation does not need to start a special fan or the like, and since it is performed in association with daily cleaning work, it does not require time and electricity.
