BACKGROUND OF THE INVENTION
The present invention relates to a circulator that circulates indoor air and uniformizes the temperature distribution in the room in order to improve the efficiency of indoor air conditioning by an air conditioner such as an air conditioner.
[0002]
[Prior art]
When the room is cooled and heated by the air conditioner, warm air is collected near the ceiling and cold air is collected near the floor, so that the efficiency of indoor air conditioning by the air conditioner decreases.
[0003]
In order to solve this problem, there is known a circulator that circulates warm air near the ceiling in the room and cold air near the floor to equalize the temperature distribution in the room and improve the efficiency of room air conditioning by the air conditioner. Yes.
[0004]
For example, circulators disclosed in Japanese Utility Model Laid-Open Nos. 57-139126 and 56-148530 are known. This circulator is equipped with a blower inside a long box-shaped or cylindrical main body, and vents are formed in the upper and lower parts of the main body. By driving the blower, the air near the ceiling and the air near the floor are It is a structure that circulates through the inside.
[0005]
According to this circulator, the indoor air temperature can be made uniform by mixing warm air near the ceiling and cold air near the floor, thereby improving the indoor air conditioning efficiency of the air conditioner.
[0006]
[Problems to be solved by the invention]
There are times when the room is ventilated when the room is cooled or heated by an air conditioner. In particular, in the case of a heater that burns oil, gas, or the like, combustion gas accumulates in the room, and therefore the window is opened at regular intervals to ventilate the room. The room is also ventilated when the indoor air becomes dirty due to smoking or sweating.
[0007]
As mentioned above, it is very troublesome to open the window and ventilate the room, so it is conceivable to install a ventilation fan to automatically ventilate the room, but for that purpose, a ventilation fan should be installed outside the air conditioner and circulator. It must be installed, and air conditioning equipment becomes expensive.
[0008]
In addition, when a ventilation fan is installed, the ventilation fan can be seen from the room and the appearance is deteriorated. In particular, in the case of a Japanese-style room or the like, the room has a Japanese-style feeling, and if a ventilation fan is seen, the Japanese-style feeling is weakened and the occupant feels uncomfortable.
[0009]
Therefore, an object of the present invention is to provide a circulator that can solve the above-mentioned problems.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1, 2, and 3, an upper main body 1 and a lower main body 2 are connected to each other by an intermediate main body 3 so as to expand and contract to form a main body 4. The upper main body 1 has a long hollow shape having a rectangular cross section and an opening at the lower portion of an upper plate 5, a front plate 6, a rear plate 7, and left and right side plates 8, 8.
[0020]
An opening 9 is formed in the upper portion of the front plate 6, and a plurality of fins 10 are attached to the opening 9 at intervals in the vertical direction. Thereby, the upper vent 11 is formed.
[0021]
An exhaust port 12 is formed near the upper portion of the back plate 7. An exhaust duct 13 is fixed along the periphery of the exhaust port 12.
[0022]
A blower 14 is attached inside the upper and lower middles of the upper body 1. This blower 14 is a sirocco fan blower provided with a casing 15, a fan 16 and an electric motor 17. The casing 15 is fixed to the plate 18, and air is discharged from the hole 19 of the plate 18.
[0023]
The lower body 2 has a long hollow shape with a rectangular cross section at the front plate 20, the back plate 21, the left and right side plates 22, 22, and the lower plate 23, and has the same cross-sectional shape as the upper body 1. It is as a size.
[0024]
The lower portion of the front plate 20 is bent in a substantially square shape to have an obliquely downward portion 20a, and an opening 24 is formed in the obliquely downward portion 20a to form a lower vent 26.
[0025]
A dust removing filter 27 is attached to the lower vent 26. In addition, you may combine the deodorizing filter 28 with the filter 27 for dust removal as shown by the virtual line in FIG.
[0026]
The intermediate body 3 has a cylindrical shape having a rectangular cross section and an upper portion and a lower portion opened by a front plate 30, a rear plate 31, and left and right side plates 32, 32. The upper portion of the intermediate body 3 is slidably fitted into the upper body 1, and the lower portion of the intermediate body 3 is slidably fitted into the lower body 2.
[0027]
Thereby, the main body 4 is adjustable in length.
[0028]
As shown in FIGS. 2 and 3, the main body 4 is disposed along the wall 33, the upper surface plate 5 is in contact with the ceiling 34, and the lower surface plate 23 is in contact with the floor 35. The exhaust duct 13 protrudes from the hole 36 of the wall 33 to the outside and is covered with a weather cover 37.
[0029]
Thus, when the blower 14 is driven, the air in the vicinity of the floor 35 is sucked from the lower vent 26 as shown by the arrow a, and a part of the air is discharged from the exhaust vent 12 and the exhaust duct 13 to the outside. . The remaining air is discharged from the upper vent 11 near the ceiling 34 as indicated by the arrow b. Thereby, the air near the floor 35 and the air near the ceiling 34 circulate through the inside of the main body 4 and the room can be ventilated.
[0030]
In addition, dust that has accumulated on the floor 35 or has risen from the floor 35 due to walking or the like is collected by the dust filter 27, so that the dust is not discharged again from the upper vent 11 into the room and is hygienic. .
[0031]
When the deodorizing filter 28 is attached, the odor of the inhaled air is deodorized by the deodorizing filter 28, so that odorless air can be discharged from the upper vent 11 into the room.
[0032]
Further, since the lower vent 26 is inclined downward, air near the floor 35 can be efficiently sucked. Further, by adjusting the length of the main body 4, the upper surface plate 5 can be pressed against the ceiling 34 and the lower surface plate 23 can be pressed against the floor 35, so that the main body 4 can be installed stably.
[0033]
As shown in FIGS. 4, 5, and 6, a first air passage 42 that communicates with the upper vent 11 by attaching a horizontal partition plate 40 and an L-shaped vertical partition plate 41 inside the upper portion of the upper body 1, A second air passage 43 communicating with the exhaust port 12 is formed.
[0034]
The horizontal partition plate 40 has a first hole 45 communicating the first air passage 42 with the discharge side chamber 44 of the blower 14 and a second hole communicating the second air passage 43 with the discharge side chamber 44 of the blower 14. 46 is formed. The chamber 44, the first hole 45, and the first air passage 42 form a circulation air passage, and the chamber 44, the second hole 46, and the second air passage 43 form a ventilation air passage.
[0035]
A plate 47 is slidably provided by a guide 48 on the lower surface of the horizontal partition plate 40. An L-shaped arm 49 is fixed to the plate 47, and the arm 49 protrudes from the long hole 50 of the front plate 6 and has a knob 51 attached thereto. Thus, the switching damper 52 is configured.
[0036]
If the plate 47 is at the intermediate position shown in FIG. 6, the opening areas of the first hole and the second hole 46 are the same as shown in FIG. 7A, and the first air passage 42 and the second air passage 43 are the same. Air volume flows.
If the plate 47 is moved to one side (left side) in FIG. 6 with the knob 51, the opening area of the first hole 45 increases and the opening area of the second hole 46 decreases. When the plate 47 is moved to the maximum stroke in one direction, the opening area of the first hole 45 is maximum and the second hole 46 is closed as shown in FIG.
[0037]
If the plate 47 is moved to the other side (right side) in FIG. 6 with the knob 51, the opening area of the second hole 46 increases and the opening area of the first hole 45 decreases. When the plate 47 is moved to the other maximum stroke, the opening area of the second hole 46 is maximum and the first hole 45 is closed as shown in FIG. 7C.
[0038]
Thus, the ratio of the circulating air volume and the ventilation air volume can be changed by the switching damper 52, and only the circulation or the ventilation can be performed.
[0039]
Therefore, the indoor ventilation air volume can be set arbitrarily.
For example, the required ventilation air volume per resident varies depending on the activity state of the resident, but 20 to 30 m ³ / h is appropriate. When this is a normal use state and indoor air is contaminated by indoor smoking or sweating, etc., the first hole 45 is closed and the second hole 46 is closed to ventilate 100% (at this time indoor circulation) Can be 0%). In addition, ventilation air volume can be increased when smoking.
[0040]
The plate 47 may be automatically moved using an electric motor, a feed screw and a nut.
[0041]
Next will be described a second embodiment of the present invention.
As shown in FIGS. 8 and 9, an intermediate vent 60 is formed at a position below the blower 14 in the front plate 6 of the upper body 1. The deodorizing filter 28 is attached to the intermediate portion vent 60.
[0042]
If it does in this way, the air of the indoor part of the up-down direction in the room will be sucked in from the middle part vent 60 by driving blower 14. Since the odor in the sucked air is deodorized by the odor filter 28, air without odor can be discharged into the room.
[0043]
Therefore, it is possible to efficiently deodorize the odor of cigarettes, which is a typical odor. In other words, when you smoke in the living room, you usually smoke while sitting on the floor or chair. At this time, the position of the smoker's cigarette and the position of the smoke outlet are almost the same height, and further the smoke of the cigarette rises, so the middle vent 60 is located in the middle of the indoor height direction. This makes it possible to efficiently deodorize the smell of tobacco.
[0044]
【The invention's effect】
According to the first invention, by driving the blower 14, indoor air is sucked from the lower vent 26 , a part of the air is discharged to the outside through the exhaust vent 12, and the remaining air is discharged to the upper vent 11. To the room.
[0045]
As a result, the air near the floor in the room and the air near the ceiling can be circulated through the inside of the main body 4, and the room air can be ventilated by discharging the air outside the room.
[0046]
Therefore, simply installing a circulator can improve the air-conditioning efficiency of the room by using the air-conditioning equipment, and it can ventilate the room.Therefore, troublesome ventilation operation is unnecessary, the air-conditioning equipment is inexpensive, and the room looks good. Become.
[0047]
In addition, since the ratio of the ventilation airflow and the circulation airflow can be changed by the switching damper 52, the ventilation airflow is usually reduced and the circulation airflow is increased to improve the cooling / heating efficiency. The room can be well ventilated.
[0049]
According to the second aspect of the invention, since the smoke when smoked indoors is intensively sucked from the middle vent 60, the smell of the cigarette is efficiently deodorized by the deodorizing filter 28, and the air without the smell of the cigarette. Can be discharged into the room.
