Description

INDUSTRIAL APPLICABILITY According to the present invention, an air conditioner outdoor unit capable of lowering the temperature of hot air (warm air) blown from an outlet of an outdoor unit of an air conditioner (hereinafter referred to as an air conditioner) for, for example, a household or an office as an air conditioner. The present invention relates to a blowout hot air temperature lowering device and an air conditioner outdoor unit equipped with the device.

Conventionally, for example, in a household air conditioner, an air conditioner indoor unit (hereinafter referred to as an indoor unit) installed on the upper part of an indoor wall surface and an air conditioner outdoor unit installed on the ground near the outdoor outer wall (hereinafter referred to as an outdoor unit). The air conditioner is heated and heated by transferring heat between the outdoor unit and the heat exchanger built in each of the indoor units using a refrigerant and a compressor.

The drain (drain) water generated when heat is exchanged by the heat exchanger of the indoor unit is stored in a drain pan (water tray) provided in the indoor unit, and the upper end (base end) of the drain hose is connected to this drain pan. By piping the lower end (tip) of the drain hose to the vicinity of the outdoor unit, the drain water is drained to a drainage ditch provided on the ground near the outdoor unit. As a publication relating to a drain hose of an air conditioner, for example, Patent Document 1 is disclosed.

Japanese Patent Application Laid-Open No. 2015-19441

However, in a conventional air conditioner having an outdoor unit and an indoor unit, the tip of the drain hose is installed in an open state on the ground, and the drain water in the drain hose is drained as it is on the ground near the outdoor unit. Therefore, not only the drain water itself is not effectively used, but also the following problems may occur in the drain hose.

That is, if the tip of the drain hose is simply installed (left) on the ground in an open state, cockroaches, insects, etc. will enter the drain hose from this opening when the air conditioner does not operate (especially when the air conditioner is not used frequently as in winter). It may settle down, which is not good for hygiene and may adversely affect the drainage performance when the air conditioner is operating. In addition, if the tip of the drain hose is open, when the outdoor wind is strong, the wind enters the drain hose from the opening and makes a "poco-poco sound". It is difficult to maintain the quietness of the room due to the state of occurrence, and for example, a member for preventing the ingress of wind is purchased separately and attached one by one.

Further, in the conventional air conditioner, the high temperature air exchanged by the outdoor unit is released as warm air (hereinafter referred to as hot air in the present invention) to the outside of the outdoor unit (in the atmosphere) by the rotation of the fan of the outdoor unit (heat dissipation). However, the actual situation is that this hot air is also blown out as it is to the outside through the air outlet provided on the front surface of the housing of the outdoor unit.

By the way, in recent years, the global warming has progressed, and abnormal weather such as an increase in outside temperature has occurred in various places, and countermeasures against it are being studied on a global scale. In particular, heat stroke has frequently occurred in recent years due to the rise in outside air temperature, and it has become indispensable to use air conditioners as a countermeasure. Under such circumstances, the applicant can set the temperature of the hot air blown (released) from the outdoor unit of the air conditioner during the cooling and dehumidifying operation of the household air conditioner that is widely used in almost all households. Based on the idea that if it can be lowered as much as possible without lowering the temperature, it may contribute to the reduction of the outside temperature as well as the measures against heat stroke. Research has led to the present invention.

BB line arrow view of FIG.

Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 and 2, the blown-out hot air temperature lowering device 1 according to the present invention is installed from the upper surface 2f to the front surface 2g of the housing of the outdoor unit 2 constituting the home air conditioner together with the indoor unit 3. ..

That is, as shown in FIGS. 4 and 5, the blown-out hot air temperature lowering device 1 has an installation member 4 mounted on the upper surface 2f of the outdoor unit 2 and a lower surface on one end side in the width (front-back) direction of the installation member 4. It has a pipe member 5 having a predetermined length arranged in the pipe member 5 and a breathable filter member 6 arranged on the lower surface (bottom surface portion) of the pipe member 5.

The installation member 4 is formed of, for example, a plate-like body such as wood or resin having a heat-shielding (heat-insulating) effect, and is arranged in a mounted state so as to cover substantially the entire surface of the upper surface 2f of the outdoor unit 2. At this time, as the installation member 4, a plate-like body of an appropriate material and color that can obtain an effect of protecting the upper surface 2f of the outdoor unit 2 and a design effect on the upper surface 2f is used in addition to the heat shielding effect. .. Further, at a predetermined position of the installation member 4, an opening 4a used for fixing and supporting the tip end portion of the drain hose 9, which will be described later, is provided.

Further, the pipe member 5 is made of resin, for example, and is formed of a circular pipe having a length corresponding to substantially the left-right width direction of the outdoor unit 2, and is fixed to the lower surface of one end side (front end side) of the installation member 4 by an appropriate fixing means. Has been done. Both ends of the pipe member 5 are closed, and as shown in FIGS. 6 and 7, the partition wall plate 7 is fixedly arranged at the center position of the inside, so that the internal space has an upper and lower two-layer structure, that is, an upper space. It has a structure having two spaces, 5a1 and a lower space 5a2.

Then, at the central portion of the uppermost portion of the pipe member 5 in the longitudinal direction, one opening 5b formed of a circular hole as an inflow port (supply port) for drain water, which will be described later, is formed, and the opening of the pipe member 5 is described. A predetermined number of openings 5c formed of circular holes or elliptical holes as drain water outlets (outlets) are formed along the longitudinal direction of the circular pipe on the bottom surface portion facing 5b in the vertical and vertical radial directions. ..

Further, at a predetermined position of the partition plate 7 built in the pipe member 5, the drain water flowing into the upper space 5a1 of the pipe member 5 is used as a flow port composed of a large number of circular holes for flowing into the lower space 5a2. The opening 7a is formed. At this time, the opening 7a of the partition plate 7 and the opening 5c of the bottom surface portion are set so that their opening positions do not coincide with each other in the longitudinal direction and the diametrical direction of the circular pipe 5a when viewed from the upper surface.

The breathable filter member 6 is fixed to the bottom surface of the pipe member 5 by an appropriate fixing means so as to extend downward in a substantially vertical state, and has a rectangular outer frame 6a made of resin, for example. The filter material 6b arranged in the outer frame 6a is provided. At this time, the filter material 6b is formed of, for example, a thick non-woven fabric, a resin or metal mesh-like member, a honeycomb-like member, or the like, and has a predetermined thickness to ensure sufficient air permeability. There is. In the drawings, for convenience of explanation, a mesh-like member having a large mesh is shown.

Further, on the upper side of the outer frame 6a of the breathable filter member 6, an opening 6a1 (see FIG. 7) that communicates with the opening 5c at the bottom surface of the pipe member 5 in the vertical direction is formed in a predetermined form. Since the breathable filter member 6 is exposed to the hot air blown from the outlet 2e of the outdoor unit 2 when the air conditioner is operated, a material having excellent heat resistance is used. Further, the filter material 6b is removable from the outer frame 6a, for example, and can be cleaned or replaced.

As described above, the filter material 6b is not limited to the mesh-like member in which the illustrated thread material 6b1 is regularly connected, and for example, the non-woven fabric or the thread material 6b1 is irregularly (randomly) connected in a mesh-like shape. It is possible to use an appropriate material having predetermined air permeability and allowing drain water to flow naturally, such as a member or a honeycomb-shaped member in which a large number of spaces are regularly or irregularly formed.

Further, the shape such as the size of the installation member 4 is set according to the shape of the outdoor unit 2. However, when the installation member 4 is installed in the outdoor unit 2 as described later, the breathable filter member 6 blows the outdoor unit 2. Since the size that covers almost the entire area in front (outside) of the outlet 2e is appropriate in terms of the effect of lowering the temperature of the hot air, for example, there are a plurality of types depending on the outer shape of the existing outdoor unit 2 and the size of the outlet 2e. It is preferable to set it.

By the way, as shown in FIG. 1, in the outdoor unit 2, a heat exchanger 2a, a fan 2b, a compressor 2c and a valve 2d are arranged inside the housing, and the outdoor unit 2 is located on the upper part of the inner surface of the outer wall 12 of a building 11 such as a house. It is connected to the installed indoor unit 3 by two pipes 8a and 8b for circulating a refrigerant and an electric wiring 8c shown in FIG. Further, as shown in FIG. 3, the indoor unit 3 has a heat exchanger 3a, a fan 3b, and a drain pan 3c arranged in the housing thereof, and water droplets 15 generated in the heat exchanger 3a are below the heat exchanger 3a. It is naturally dropped and accommodated in the drain pan 3c arranged in the drain pan 3c, and drained to the outdoor unit 2 side via the drain hose 9 whose base end is connected to the drain pan 3c.

As a result, the air conditioner is configured by the outdoor unit 2 and the indoor unit 3, and as shown in FIG. 1, a refrigerant and a compressor 2c are inserted between the outdoor unit 2 and the indoor unit 3 having built-in heat exchangers 2a and 3a. By using it to transfer heat, it is designed to cool (dehumidify) and heat.

Next, the installation method of the blown-out hot air temperature lowering device 1 and its operation will be described. First, in the blown hot air temperature lowering device 1, the installation member 4 is placed on the upper surface 2f of the existing outdoor unit 2 installed on the ground 13 via the installation table 17 (see FIGS. 1 and 2). Therefore, the outdoor unit 2 is mounted and installed in front of the outlet 2e with a predetermined interval d (see FIG. 5). At the time of this installation, the pipes 8a and 8b and the electrical wiring 8c connected to the indoor unit 3 are left as they are (current state), and only the predetermined length portion of the drain hose 9 on the outdoor unit 2 side can be repositioned. It is in a state of being.

Then, the tip of the free portion of the drain hose 9 is attached to the opening 4a of the installation member 4 and the opening 5b of the pipe member 5 which are installed on the upper surface 2f of the outdoor unit 2 and communicate with each other in the vertical direction. 6 and 7 are connected (connected) by inserting from above as shown by the two-dot chain line. Further, the tip portion of the drain hose 9 located on the upper surface 2f of the outdoor unit 2 is connected to the installation member 4 with a binding band by using, for example, an opening (not shown) provided in the installation member 4, so that the installation member 4 can be connected to the installation member 4. Place it fixedly on top.

The free portion of the drain hose 9 on the outdoor unit 2 side is set at a position at least higher than the height position of the installation member 4 of the blown hot air temperature lowering device 1 from the ground 13 to completely cover the entire length of the drain hose 9. It is preferable to pipe so that a smooth water gradient is formed. As a result, the drain water discharged from the drain pan 3c of the indoor unit 3 is satisfactorily supplied to the blown hot air temperature lowering device 1 installed via the drain hose 9.

As shown in FIG. 5, in the blown-out hot air temperature lowering device 1 installed in the outdoor unit 2, the breathable filter member 6 has a predetermined interval d in front of the blowout port 2e of the outdoor unit 2 and is in a hanging state. Although it is arranged, it is preferable that this interval d is as small as possible within a range that does not adversely affect the blowing performance of hot air, but this interval d is positioned in the front-rear direction according to the blowing capacity of the outdoor unit 2 and the like. It may be arranged so that the dimensions) can be adjusted. Further, in order to prevent the blowout hot air temperature lowering device 1 from shaking due to the outdoor wind, as shown by the alternate long and short dash line in FIG. For example, the air outlet 2e or the slit of the louver provided at the air outlet 2e may be used for fixed support.

The blown-out hot air temperature lowering device 1 installed in this way operates as follows. That is, when the air conditioner, for example, the air conditioner is operated by operating the remote controller in the room, the indoor unit 3 takes in the high temperature air in the room into the indoor unit 3 as shown by the arrow C in FIG. 1 and rapidly cools it by the heat exchanger 3a. This chilled air is discharged into the room as cold air as shown by the arrow d. At this time, as shown in FIG. 3, the moisture contained in the air becomes water droplets 15, which adhere to the heat exchanger 3a and fall downward, are housed in the drain pan 3c, and are housed in the drain hose 9 via the indoor unit 3 It is drained from the room to the indoor unit 2 side by natural flow.

On the other hand, the outdoor unit 2 supplies the indoor unit 3 as cold air by exchanging heat with the heat exchanger 2a and compressing the high-temperature air taken in by the indoor unit 3 with the compressor 2c. At this time, the high-temperature air generated during heat exchange by the heat exchanger 2a of the outdoor unit 2 is generated by the rotation of the fan 2b provided in front of the heat exchanger 2a, as shown by the arrow a in FIG. It is discharged (heated) as hot air from the outlet 2e to the outside of the outdoor unit 2 (in the atmosphere), that is, blown out.

This hot air passes (ventilates) the filter material 6b of the breathable filter member 6 of the blowout hot air temperature lowering device 1 installed in front of the blowout port 2e by a predetermined distance d, and passes through (ventilates) the outside of the blowout hot air temperature lowering device 1. Is released to. At the same time, the drain water generated during the cooling or dehumidifying operation of the air conditioner flows down the drain hose 9 and is supplied into the pipe member 5 of the blown hot air temperature lowering device 1. At this time, the drain water in the drain pan 3c in the indoor unit 3 is satisfactorily supplied into the pipe member 5 because the water gradient is set in the entire area of the drain hose 9.

Then, as shown in FIGS. 6 and 7, the drain water supplied into the pipe member 5 of the blown hot air temperature lowering device 1 is first supplied (inflowed) into the upper space 5a1 from the opening 5b of the pipe member 5. This flows down from the opening 7a of the wall plate 7 into the lower space 5a2. At this time, by providing the opening 7a of the partition plate 7 at, for example, the center of the partition plate 7 in the width direction and both ends thereof, the drain water supplied into the upper space 5a1 is downward from the central opening 7a of the partition plate 7. The outside of the pipe member 5, that is, the drain water is indicated by the arrow in the figure. It will flow down as in (b) and be supplied to the upper part of the breathable filter member 6.

The drain water supplied through the opening 6a1 on the upper side of the outer frame 6a of the breathable filter member 6 slowly and naturally flows downward while adhering to the surface of the thread material 6b1 of the filter material 6b. The drain water adhering to the thread material 6b1 of the filter material 6b at the time of flow cools the hot air of the outdoor unit 2 passing through the gap 16 between the thread materials 6b1, that is, the hot air of the outdoor unit 2 drains. When passing through the gap 16 of the filter material 6b containing water, the drain water evaporates, the heat of vaporization is taken away, the temperature of the filter material 6b drops, and the wind passing through the filter material 6b is outside. As a result, the temperature of the hot air blown from the outdoor unit 2 is lowered by being discharged toward the side.

Although it is affected by the temperature of the outside air (the temperature inside the indoor unit 3), the drain water is drained substantially continuously during the cooling operation and the dehumidifying operation of the air conditioner, so that the temperature of the blown hot air drops. By using this drain water by the device 1, it becomes possible to lower the temperature of the hot air cooked from the outdoor unit 2 by a predetermined temperature. That is, the blown-out hot air temperature lowering device 1 makes it possible to lower the temperature of the hot air of the outdoor unit 2 for which no measures have been taken in the past by effectively using the drain water which was conventionally in the draining state. Therefore, considering the number of existing air conditioners installed, it can be highly expected as a measure against global warming.

As described above, according to the blown-out hot air temperature lowering device 1, the installation member 4, the pipe member 5, and the breathable filter member 6 are provided, and the breathable filter is provided from the opening 5c provided in the bottom surface portion of the pipe member 5 in a predetermined form. Since the temperature of the hot air blown from the outlet 2e of the outdoor unit 2 can be lowered by flowing the drain water through the member 6, the drain water drained from the drain hose 9 of the air conditioner can be effectively used. Therefore, the temperature of the hot air from the outdoor unit 2 can be lowered, which can contribute to the suppression of the rise in the outdoor air temperature by the outdoor unit 2.

At the same time, it is no longer necessary to drain the drain water drained from the drain hose 9 onto the ground 13 as it is, and the opening at the tip of the drain hose 9 is abbreviated by the blowout hot air temperature lowering device 1 (pipe member 5 and breathable filter member 6). Since it can be in a closed state, it is possible to reliably prevent deterioration in hygiene and deterioration in drain water discharge performance when the air conditioner is operated. In addition, it is possible to prevent the outdoor wind from entering the drain hose 9, and it is possible to prevent the generation of abnormal noise when the air conditioner is operating, such as "poco-poco noise", and to maintain sufficient quietness in the room, or to prevent the ingress of wind. It is possible to solve various conventional problems related to the drain hose 9 at once, such as eliminating the need to install a member or the like for prevention.

Further, since the installation member 4 is formed of a substantially flat plate-shaped body that can be installed on the upper surface 2f of the outdoor unit 2, the pipe member 5 is arranged in a substantially horizontal state at the front end portion of the plate-shaped body. The blowout hot air temperature lowering device 1 can be easily installed by using the upper surface 2f or the like of the outdoor unit 2, for example, and can be easily attached and detached. Further, since the plate-shaped body as the installation member 4 has at least one function of heat shielding function, protection function, or appearance improving function, by using a predetermined plate-shaped body, the indoor unit 2 does not have a conventional shielding function. It is possible to obtain a thermal effect, a protective effect, a design effect, and the like.

Further, by disposing the partition plate 7 having an opening 7a in the entire longitudinal direction inside the pipe member 5, the inside of the pipe member 5 is composed of an upper and lower two-layer structure of an upper space 5a1 and a lower space 5a2. Since the positions of the opening 7a of the partition plate 7 and the opening 5c of the pipe member 5 are set so as to be different from each other in the vertical direction or the like, the drain water supplied in the upper space 5a1 of the pipe member 5 is placed in the lower space 5a2. While flowing down in a dispersed state, the drain water can be satisfactorily flowed down from the bottom surface portion of the lower space 5a2 to the entire upper surface of the breathable filter member 6 below, and the temperature lowering efficiency of the hot air can be further improved.

Further, since the filter material 6b of the breathable filter member 6 is formed of, for example, a thick non-woven fabric, a stitch-shaped member, a honeycomb-shaped member, or the like, by using a predetermined filter material 6b, it flows down from the pipe member 5. The passage time of the drain water through the breathable filter member 6 can be lengthened, and the efficiency of lowering the temperature of the hot air can be further improved.

By the way, in the above description, an example in which the blown-out hot air temperature lowering device 1 can be attached and installed (retrofitted) to the existing outdoor unit 2 has been described, but the present invention is not limited to this, and the above description is made at the manufacturing stage of the outdoor unit 2. Of course, it is also possible to integrate the blowout hot air temperature lowering device 1 by incorporating the blowout hot air temperature lowering device 1, that is, by incorporating the blowout hot air temperature lowering device 1 in the outdoor unit 2. In this case, the blown-out hot air temperature lowering device 1 is composed of the pipe member 5 and the breathable filter member 6, and this is placed between the fan 3c in the housing of the outdoor unit 2 and the inner surface of the housing in front of the fan 3c. , It may be attached by an appropriate attachment device or the like corresponding to the installation member 4, or may be directly attached to the front surface 2g of the housing by an appropriate attachment device or the like.

Even with this configuration, the blowout hot air temperature lowering device 1 can be integrally arranged on at least one of the inner surface and the outer surface (outside the front surface 2 g) of the outlet 2e in front of the fan 2b of the outdoor unit 2. Similar to the embodiment, the drain water can be effectively used to lower the temperature of the hot air blown from the outdoor unit 2, and various problems caused by the drain hose 9 can be solved at once.

Further, the blown hot air temperature lowering device 1 is composed of a pipe member 5 and a breathable filter member 6, and these are arranged in the housing of the outdoor unit 2 or are closely fixed to the front surface 2g and integrated into the outdoor unit 2. Therefore, the blown-out hot air temperature lowering device 1 can be built in while being compactly formed, and the outdoor unit 2 can be prevented from becoming larger and the appearance of the outdoor unit 2 being deteriorated, and the blown-out hot air temperature lowering device 1 is integrated in the housing in advance. Since it is assembled in a specific manner, the installation work of the outdoor unit 2 and the like can be performed substantially in the same manner as in the conventional case.

In the above embodiment, the installation member 4 is placed horizontally on the upper surface 2f of the outdoor unit 2, but for example, the installation member 4 is placed in a front-rear inclined state in which the front surface 2g side of the outdoor unit 2 is lowered, and drain water flows in. May be further promoted, or a flange portion extending downward is provided at both ends of the installation member 4 in the longitudinal direction and covered with three sides of the upper surface of the outdoor unit 2 to stabilize the installation state of the installation member 4. It may be in the form.
