Abstract

PURPOSE:To uniformize indoor temperature, by a method wherein a blast fan is situated in the middle of a regulated air flow passage, and an air suction position and an air discharge position are selectively and respectively set to either a high or a low level in working environment. CONSTITUTION:A circulator 1 is provided with a blast fan 5 situated in the middle of the interior of a cylindrical body 2, and through drive of the blast fan 5, an air flow is generated. Namely, in the interior of the cylindrical body 2, a portion running between a suction port 3 and a discharge port 4 forms a substantially regulated air flow passage 6. The air flow passage is formed sufficiently long, the suction port 3 is situated in the upper part of the indoor and the discharge port 4 in the lower part thereof, or inversely the suction port 3 in the lower part and the discharge port 4 in the upper part. As noted above, since an air suction position and an air discharge position are selectively set in either a high or a low level in working environment of a device, indoor temperature can be effectively uniformized.

Description

DETAILED DESCRIPTION OF THE INVENTION <<Object of the Invention>><<Industrial Application Field>> The present invention relates to a circulator that equalizes indoor temperature, etc.

<<Background of the Invention>> Air conditioning equipment is widely used to control indoor temperature to suit the purpose. However, due to the nature of air, the temperature distribution tends to be higher in the upper part of the room and lower in the lower part. Of course, some types of air conditioning equipment and heating and cooling equipment take this into account and blow hot air downward, while some cool air is blown upward. However, in reality, desks, chairs, other furniture, and office equipment are installed in rooms equipped with these facilities, so ideal air circulation may not always be achieved.

(Technical matters attempted to be developed) The present invention was made in view of this background,
This is an attempt to develop a new circulator that can more effectively equalize indoor temperature.

(Structure of the Invention) <Means for Achieving the Object> That is, the circulator of the present invention provides a blower fan in the middle of a substantially regulated air flow path, and drives the blower fan to blow air into the air flow path. In a device that circulates air by sucking it in from one end and blowing it out from the other end, the regulated air flow path is formed sufficiently long, and the air suction position and the air blowout position are mutually within the operating environment of the device. It is characterized by being selectively set at either a high or a low position, thereby achieving the above object.

(Example) The present invention will be specifically described below based on the illustrated example. Reference numeral 1 designates a circulator according to the present invention, which is composed of a cylindrical main body 2 as an outer shell member.

The upper part of this cylindrical main body 2 is opened to form a suction port 3, and the lower part thereof is also opened to form a blow-off port 4. Figure 1~
1) In the embodiment shown in Figure 1, the suction port 3 and the blowout port 4 are cut out diagonally, and some slits are formed on the sides so that air can be sucked in or blown out. do. A blower fan 5 is provided midway inside the cylindrical body 2, and by driving the blower fan 5, an air flow is generated. That is, the space between the suction port 3 and the blowout port 4 inside the cylindrical body 2 becomes a substantially regulated air flow path 6, and in many cases, the suction port 3 is connected to a room where the device is placed, etc. An air outlet 4 is provided below in the operating environment of the air conditioner. However, it is of course possible to provide the suction port 3 at the bottom and the outlet 4 at the top. Each of the above members will be explained in more detail below. First, the cylindrical main body 2 is composed of a back plate 10 having sufficient strength as a frame, and a front plate 1) placed in front of the back plate 10.
Similarly, the front plate 1) has a nearly U-shaped horizontal cross section.
It is constructed into a cylindrical body.

Note that since both the back plate 10 and the front plate 1) have a sufficiently long overall length in the height direction, in this embodiment, they are divided in the middle and combined.

Of course, these structures can be constructed to meet appropriate manufacturing requirements, such as by combining shapes that are further divided. Reference numeral 12 denotes a bracket fixed to the back plate 10, and the circulator 1 can be installed at a predetermined position indoors by hooking one end of this bracket 12 to another member fixed to the wall surface W, for example. Ru. Furthermore, an upper louver unit 13 is attached to the upper suction port 3 of the cylindrical body 2 so as to be fitted therein, and has a large number of louver fins 14 whose guiding direction is set in the vertical direction. Incidentally, the upper louver unit 13 and the cylindrical main body 2 are assembled using screws or rib lifts as appropriate.

On the other hand, a lower louver unit 16 is provided on the side of the air outlet 4 in the cylindrical body 2, and this also has a shape almost similar to the shape of the area near the air outlet 4 below the cylindrical body 2, It is attached so that it is fitted inside. A guide plate 17 is obliquely installed above the lower louver unit 16 to guide the air that has moved downward through the air flow path 6 so as to further bring it closer to the back plate 10 side of the cylindrical main body 2. Horizontal guide louvers 18 are provided in several stages sequentially from near the lower end of the guide plate 17 along the diagonally cut out outlet 4. Further in contact with this horizontal guide looper 18, an expansion guide looper 19 is provided on the air blowing side to expand the air in the horizontal direction and blow it out. The blower fan 5 is provided between the upper and lower ends of the cylindrical body 2, and is attached to the output shaft of a motor M supported by a motor mount bracket 21. . Although the main structure of the circulator 1 of the present invention is as described above, the following members are further provided to perform auxiliary functions or auxiliary functions. First, code 2
Reference numeral 3 denotes an air filter, which is one of the air quality improvers, and is made of various members that purify the air, such as filter paper, wet steel wool, or activated carbon, formed into a plate shape, for example. Further, the reference numeral 24 is a fragrance agent which is another air quality improving agent. These air filters 23 and air fresheners 2
4 may be provided upstream of the blower fan 5 in the air flow path 6 formed by the cylindrical body 2, but of course, it may be provided downstream of the blower fan 5 in the air flow path 6.
Alternatively, each may be provided separately on the upstream side and the downstream side. Reference numeral 25 denotes an opening/closing hood, which is installed on the front panel 1) in consideration of maintenance and inspection when an air quality improver such as the air filter 23 or air freshener 24 is installed in the air flow path 6. This is a part that can be opened and closed freely. Of course, the opening/closing form of the opening/closing hood 25 may be, for example, as shown in FIG. 8(a), by using the upper part of the cylindrical body 2 as a hinge point, and opening and closing the hood 25 so that the lower part protrudes, or as shown in FIG. 8(b). As shown, it may be a so-called side-opening door, or it may be configured so that the entire door can be removed forward, as shown in FIG. 3(C). Furthermore, the embodiment shown in FIG. 9 is an embodiment equipped with a stand 26 to provide independence so that the circulator 1 can be easily moved from one place to another when the circulator 1 is installed.

Therefore, in the case of the embodiment shown in FIG. 9, the installation position is not limited, and the installation position can be selected and changed to suit the indoor situation. Further, the embodiment shown in FIG. 10 is an embodiment in which the circulator 1 is fixed to a wall surface W, etc., but in order to make the installation work easier, for example, fixing pieces 27 are provided on the upper and lower sides, and these are attached to the fixing pieces 27. A male screw is carved into the rod integrally formed with the rod, so that the length of the fixed piece 27 can be adjusted. This is what I decided to do. Incidentally, the shape of the cylindrical body 2 is not limited to the above-mentioned embodiment, and in short, the shape of the cylindrical body 2 is not limited to the above-described embodiment.
Since it is sufficient that air is sucked in from above and blown out from below, for example, as shown in Fig.
A blower outlet 4 may also be provided.

The present invention has the specific structure as described above, and its use is carried out as follows. First, if the circulator 1 is to be fixed to a wall surface W or the like, it is attached by appropriate construction, and if it is provided with a stand 26 or the like, it is appropriately installed at a desired position. Thereafter, when the motor M is started, the blower fan 5 rotates, and the inside of the cylindrical main body 2 is used as an air flow path 6 to suck in air through the suction port 3 and discharge the air through the blowout port 4.

When doing this, warm air from above is sucked in through the suction port 3 and blown out from the air outlet 4 below, so, for example, in the case of heating, warm air is blown out from below in a concentrated manner, creating a more comfortable indoor environment. can be obtained. Of course, if the air filter 23 and the aromatic agent 24 are provided at this time, the air is also purified, and a pleasant scent from the aromatic agent 24 is supplied into the room. In particular, in this embodiment, the lower louver unit 16 in the air outlet 4 that blows out air smoothly guides the air flowing downward from above in the horizontal direction, and actively guides the air so that it spreads in at least three directions from there. As a result, the air from the outlet 4 is not concentrated at one point, and a preferable dispersed state is obtained. Of course, even during cooling, there is warm air at least on the ceiling side, so by sucking this in and sending it downward, the room temperature becomes more uniform, and it is possible to prevent only the feet from being excessively cooled. Although not shown in the figure, for such operation, for example, a thermostat or the like may be installed in this device or in the room in which it is installed, and this may be used to control the operating state of the blower fan 5, or a temperature sensor may be connected to the floor surface. Appropriate countermeasures can be taken, such as placing them both nearby and near the ceiling, detecting the temperature difference, and activating when the temperature difference exceeds the allowable range. The above explanation is for the most common case of so-called top suction and bottom blow-off, but in the case of top blow-off and bottom suction, the easiest way is to install the circulator 1 upside down. Of course, without reversing the entire circulator 1, the mounting positions of the upper louver unit 13 and lower louver unit 16 with respect to the cylindrical body 2 are reversed, and the blowing direction of the ventilation fan 5 is also changed by reversing the mounting positions. You may. Alternatively, it may be supplied as a specialized machine for upper blowing and lower suction from the beginning of manufacture.

(Effects of the Invention) Since the present invention has the configuration described above, it can be used in rooms where the temperature cannot be sufficiently uniformed by conventional air conditioning equipment, for example, by sucking warm air from above and blowing it out from below. This made it possible to make the temperature of the indoor air more uniform.
