Abstract

PURPOSE:To uniformize air volume over the entire sectional area of an outlet even where fan diameter is much smaller than the horizontal size of the outlet, by a construction wherein the vertical size of an outlet of a casing is smaller than the blade end-to-end size of a fan, and the horizontal size of the outlet is much greater than the fan diameter and smaller than the horizontal size of a portable main body. CONSTITUTION:An outlet 42 of a casing 43 has a vertical size A smaller than the blade end-to-end size B of a first fan 40 of eccentric multiblade type, and a horizontal size C much greater than the diameter D<phi> of the first fan 40 and approximate to the horizontal size of a front face of a main body 30. Cold air is fed to the very wide outlet 42 by the blowing action of the first fan 40, and the static pressure of the cold air is gradually raised in an air duct leading from the fan 40 to the outlet 42. The flow of cold air is dispersed in the width directions of the outlet 42, and the small vertical size of the outlet 42 ensures that the cold air is blown out at a uniform velocity. A uniform and wide blowing action is achieved, with the air volume being uniform throughout the sectional area of a cold-air outlet grille 36.

Description

Detailed Description of the Invention [Purpose of the Invention (Industrial Field of Application) The present invention is directed to, for example, housing all the equipment constituting a refrigeration cycle in the main body of an air conditioner so that the whole body of the air conditioner can be heated. The present invention relates to a portable air conditioner that can be placed at any position in an exchange room, and particularly to an improvement in a blowout structure for heat exchange air.

(Prior Art) For example, even though the area of the heat exchange chamber is relatively large, there are cases where the minimum required area of the heat exchange portion is small. Alternatively, the position of the required heat exchange site may change as appropriate.

Air conditioners used under these conditions are portable air conditioners that house all the equipment that makes up the refrigeration cycle inside the air conditioner body and can be placed in any position. It is more convenient to use a machine.

An example of this type of portable air conditioner is disclosed in, for example, Japanese Utility Model Publication No. 52-17969. Figure 22 (
The outline will be explained based on A) and the same figure (B).

The interior of the portable air conditioner main body 1 is divided by a partition wall 2 into a cooling room 3 and a machine room 4. The cooling room 3 is equipped with an evaporator 5, a cold air blower fan 6, etc., and an indoor air intake is provided on the front side. A grill 7 and a cold air blowing grill 8 are provided. The machine room 4 includes a compressor 9 and an air-cooled heat exchanger 1 which is a heating condenser.
0, a water sprinkler 11, a water-cooled heat exchanger 12 which is an evaporative condenser, a water tank 13, a pump 14, etc. are arranged, and - a heat exchange air suction grill 15 is provided on the side. The water-cooled heat exchanger 12, water sprinkler 11, air-cooled heat exchanger 10, etc. are surrounded by a wind collection cover 16. A casing 19 in which a blower 18 is disposed is connected to a discharge port 17 provided in the air collection cover 16 . The casing 19 is provided with an exhaust port body 20, to which a flexible discharge vibrator 21 communicating with the outside (not shown) is connected.

Thus, the high-temperature, high-pressure refrigerant discharged from the compressor 9 is first guided to the air-cooled heat exchanger 10, and then to the water-cooled heat exchanger 12, where it is condensed.

At the same time, the pump 14 is driven to apply pressure to the water in the water tank 13 and cause the water sprinkler 11 to spray water on the water-cooled heat exchanger 12. The sprinkled water vaporizes while taking away the heat of evaporation from the water-cooled heat exchanger 12, and is led to the air-cooled heat exchanger 10 and heated, where the temperature increases and the relative humidity decreases. The blower 18 is also driven, and the heat exchange air intake grill 1
The heat exchange air led from 5 into the machine room 4 exchanges heat with the water-cooled heat exchanger 12 and is air-cooled. Here, the water is sprinkled from the water sprinkler 11 and mixed with the evaporated water vapor to become highly humid air containing a large amount of water vapor, which is led to the air-cooled heat exchanger 10.

The air-fuel mixture, which is high-humidity air, is heated by exchanging heat with the air-cooled heat exchanger 10, and as the temperature increases, the relative humidity decreases. The high-temperature, high-humidity air after heat exchange is guided from the air collection cover 16 to the casing 19, and is discharged to the outside via the air outlet body 20 and the discharge vibrator 21. The air-cooled heat exchanger 10 exchanges heat with high-humidity air, and the water-cooled heat exchanger 12 exchanges heat with the water and heat exchange air of the water sprinkler 11, thereby condensing the refrigerant.

In this way, all the heat emitted by the air conditioner is discharged to the outside via the discharge vibrator 21, so the main body 1 can be placed at any position indoors.

Furthermore, although the air discharged outdoors is heated by the air-cooled heat exchanger 10 and has a relatively low relative humidity, it is a high-temperature, high-humidity, thermally dense gas.

Therefore, water droplets do not condense on the inner surfaces of the casing 19, the exhaust port body 20, and the discharge vibrator 21 through which it passes.

(Problem to be Solved by the Invention) Incidentally, in such an air conditioner, a cold air blower fan 6 is used as a blower for blowing cold air into the heat exchanged room.
is used. The cold air blowing fan 6 is an eccentric multi-blade fan (so-called sirocco fan).
It is fitted onto the rotating shaft of a motor with its axis oriented horizontally.

When the motor rotationally drives the cold air blowing fan 6, indoor air is taken in from the axial direction through the indoor air intake grille 7 and blown out from the circumferential direction.

Then, the cold air is first applied to the evaporator 5 and is blown from the cold air blowing grill 8 to the heat exchange room.

In order to make the heat exchange area as wide as possible in the evaporator 5,
The width dimension is set to be substantially close to the width dimension of the main body 1 as well as a sufficient vertical dimension. The cold air blowing grill 8 has an evaporator 5
, and is formed to have a sufficient vertical dimension and a width substantially close to the width of the main body 1 . Therefore, it is desirable that the cold air blown out from the cold air blowing grille 8 be blown out evenly without localized unevenness in the amount of air blown.

However, the width of the cold air blowing grill 8 is extremely large compared to its vertical dimension, and the diameter of the cold air blowing fan 6 is extremely smaller than the width, so that the cold air blowing grill 8 has a large width not only in the vertical direction but also in the width direction. It is not possible to create a uniform, so-called wide blowout.

To this end, it is conceivable to make the diameter of the cold air blowing fan 6 equal to the width of the cold air blowing grille 8.
The motor that drives this must be made larger, which may lead to an increase in air blowing noise.

Alternatively, it is also conceivable to arrange cross-flow fans facing each other across the width direction of the evaporator 5. In this case, even if the air blowing in the width direction becomes uniform, there is a possibility that uneven air blowing will occur in the vertical direction.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to: Even if the diameter of the fan is extremely smaller than the width dimension of the air outlet, the present invention can be applied to the entire surface of the air outlet in the vertical and width directions. It is an object of the present invention to provide an air conditioner that achieves uniform, so-called wide air blowing over the air and improves air blowing efficiency.

[Structure of the Invention (Means and Effects for Solving the Problems) In other words, the present invention includes a motor disposed within the main body of an air conditioner with its axis oriented vertically, and an eccentric multi-blade type mounted on the rotation axis of the motor. The above fan is fitted with a casing that has an inlet in the axial direction and an outlet in the circumferential direction, and the outlet of the casing has a dimension in the vertical direction that is larger than the dimension between both ends of the blades of the fan. This air conditioner is characterized in that the air conditioner is formed to be narrow and its width is extremely larger than the diameter of the fan and slightly narrower than the width of the air conditioner main body.

As a result, the static pressure gradually rises in the air passage inside the casing from the fan to the outlet, and the air flow concentrates in the vertical direction of the outlet and is dispersed in the width direction. The amount of air blown is made uniform over the entire surface of the outlet.

As shown in FIG. 18, a control circuit 93 consisting of a microcomputer included in this air conditioner includes switches 81 and lamps 82 on the operation panel 80, a float switch 57 provided on the tray 56, and a refrigerator. It is electrically connected to the compressor 63, the motor 39, and the alarm buzzer 94 that make up the cycle.

Next, the operation of the air conditioner constructed in this way will be explained.

As shown in FIGS. 1 to 3 again, the compressor 63 is driven to compress the refrigerant and discharge it in a high temperature and high pressure state. At the same time, the motor 39 is energized to drive the first fan 40, the second fan 50, and the sprinkler 58 all at once. The refrigerant is guided from the air-cooled heat exchanger 45 to the water-cooled heat exchanger 53, where it exchanges heat and condenses. Further, it is led to a capillary tube 65, where the pressure is reduced, and then led to an evaporator 38, where it is evaporated. Heat exchange air from the heat exchange chamber is guided to the evaporator 38, where it exchanges heat with the refrigerant and removes latent heat of vaporization.

The temperature of the heat exchange air is lowered, and the cooled air is blown out again into the heat exchange room to perform this cooling effect.

On the other hand, the first fan 40 takes in heat exchange air from the suction grill 37 into the cooling room 33 . This heat exchange air is filtered by the air filter 46 and then passes through the evaporator 38, where it exchanges heat with the refrigerant and loses its latent heat of vaporization, becoming cold air and flowing into the casing 43 through the upper and lower suction ports 41a and 41b. It gets sucked in. Then, the air is again blown from the air outlet 42 of the casing 43 to the heat exchange room via the cold air blowing grille 36. This cooling effect is achieved from the point where cold air is blown into the heat exchanged room.

As shown again in FIGS. 4 and 5, the vertical dimension A of the air outlet 42 of the casing 43 is set to the first dimension A of the eccentric multi-blade type.
The width dimension C of the air outlet 42 is set to be considerably wider than the diameter Dφ of the first fan, and the width dimension C of the air outlet 42 is set substantially close to the front width dimension of the main body 30. The static pressure of the cool air sent out to the outlet 42 having an extremely wide width by the blowing action of the first fan 40 gradually increases in the air passage from the fan 40 to the outlet 42 . As a result, the wind flow is dispersed in the width direction of the air outlet 42, and since the vertical dimension is narrow, the wind speed is averaged when the air is blown to the outside. As a result, a wide and even air blowing effect is achieved with a substantially uniform air volume over the entire surface not only in the vertical direction but also in the width direction of the cold air blowing grille 36.

As shown again in FIGS. 1 and 4, the first fan 4
0, the second fan 50 is driven to rotate, and heat exchange air is taken into the machine room 34 from the heat exchange air intake grille 44. At this time, the heat exchange air is filtered by the integrated air filter 46, and the air-cooled heat exchanger 45 is free from dirt. Furthermore, since this air-cooled heat exchanger 45 is disposed close to the evaporator 38 via the partition wall 32, the air filter 46 is able to separate the indoor air guided to the evaporator 38 from the air-cooled heat exchanger 45. An integrated type can be constructed that filters both the heat exchange air and the heat exchange air. Since the partition wall 32 is interposed between the evaporator 38 and the air-cooled heat exchanger 45, there is no problem in their respective heat exchange operations. Since the air-cooled heat exchanger 45 is arranged at an angle, a sufficient amount of heat exchange air can be ensured even if the vertical dimensions of the heat exchange air intake grille 44 are reduced.

At times other than startup, the air-cooled heat exchanger 45 exchanges heat with the relatively low-temperature, low-humidity heat exchange air in the heat exchange room, which is already being cooled, so the temperature of the refrigerant introduced here is The temperature difference is large, and therefore the heat exchange efficiency is large.

The air that has passed through the air-cooled heat exchanger 45 for heat exchange is guided into the interior of the casing 47 through the upper suction port 48, and is discharged from the air outlet 51 to the outside of the heat exchanged room via the discharge hose 64.

In addition, heat exchange air is sucked into the machine room 34 from the auxiliary suction grill 59 by the action of the second fan 50, and the water tray 56 passes through the gap between the upper end circumferential surface of the water sprinkling cover 55 and the circumferential surface of the dish 56. Guided within. The heat exchange air exchanges heat with the water-cooled heat exchanger 53 disposed inside the water sprinkler cover 55,
The air is guided into the casing 47 from the lower suction port 49, joins with the air that has exchanged heat with the air-cooled heat exchanger 45, and is discharged from the discharge hose 64.

The water sprinkler 58 rotates as the motor 39 is driven, and the water receiver sucks up the water in the dish 56 along the inner peripheral surface from the lower end opening due to centrifugal force. The water that reaches the water sprinkling hole 58b and the water sprinkling window 58c flies out toward the surroundings and is sprayed. The water-cooled heat exchanger 53 arranged along the periphery of the water sprinkler 58 directly receives water from the water sprinkler 58,
Alternatively, water droplets that hit the water sprinkling cover 55 bounce back and are indirectly sprinkled. Further, water droplets received by the upper end of the water-cooled heat exchanger 53 flow down along the lower end thereof. The blades 58a provided on the outer peripheral surface of the sprinkler 58 agitate the air inside the sprinkler cover 55 as it rotates, thereby assisting in heat exchange with the water-cooled heat exchanger 53. At the same time, it receives the water droplets that have bounced off the water-cooled heat exchanger 53 and sprays water onto the water-cooled heat exchanger 53 again.

The water-cooled heat exchanger 53 receives sufficient water spraying action from the water sprinkler 58 and exchanges heat with the refrigerant introduced therein. Most of the water droplets that wet the water-cooled heat exchanger 53 flow down into the water tray 56 and are collected, and are again sprinkled with water by the water sprinkler 58. Some of the water droplets evaporate, are introduced into the sprinkler cover 55, and mix with the air that has exchanged heat with the water-cooled heat exchanger 53, becoming highly humid air. The air is introduced into the interior of the casing 47 through the lower suction port 49 and mixed with heat exchange air that has been exchanged with the air-cooled heat exchanger 45 and sucked in through the lower suction port 48 .

The highly humid air guided from the sprinkler cover 55 side exchanges heat with the air-cooled heat exchanger 45 and is then heated to relatively high temperature air.
On the way from the second fan 50 to the discharge hose 64, the air turns into low-humidity air and is discharged to the outside. Therefore, water droplets do not adhere to the second fan 50 and the discharge hose 64.

In the end, the machine room 34 includes a heat exchange air suction grill 44, an air-cooled heat exchanger 45, a lower suction port 48, and a second fan 50.
, an A ventilation path 95 leading to the air outlet 51 and the discharge hose 64;
From the auxiliary suction grill 59 to the inside of the water sprinkling cover 55, the lower suction port 4
9, the second fan 50, the air outlet 51, and eight ventilation passages 96 leading to the discharge hose 64 are formed.

The air-cooled heat exchanger 45 is arranged on the suction side of the A ventilation passage 95, and the water-cooled heat exchanger 53 is arranged on the suction side of the 8 ventilation passage 96. Since water droplets sprayed by the water sprinkler 58 do not adhere to the air-cooled heat exchanger 45, corrosion does not occur and water droplets do not clog the air-cooled heat exchanger 45, so that a reliable heat exchange effect can be obtained. The water-cooled heat exchanger 53 receives water sprinkled by the water sprinkler 58 and also comes into contact with the heat exchange air guided to the eight ventilation passages 96, so that a reliable heat exchange effect can be obtained.

Note that such high-pressure side heat exchange jlQ is expressed by the following equation.

Q ” Q+ + Q2Q, −
Kc (Tc-Ta) ...Amount of heat exchanged by the air-cooled heat exchanger 45 Q2 mcu
-G...Amount of heat exchanged by the water-cooled heat exchanger 53 c - Heat exchange coefficient of the air-cooled heat exchanger 45 (Kcal/h・℃;
c - Average refrigerant temperature in the air-cooled heat exchanger 45 (°C) Ta - Suction air temperature in the air-cooled heat exchanger 45 (°C) Cu - Latent heat of water (K cal/K g ) G - Water consumption ( Kg/h
) Assuming that the amount of heat exchange Q on the high pressure side is constant, by arranging the air-cooled heat exchanger 45 on the ventilation path 95 separate from the water-cooled heat exchanger 53, Tc-Ta increases and Ql increases. increase Instead, Q2 becomes smaller, and G decreases while Cu remains constant. That is, water consumption is reduced, the continuous operation time is significantly extended compared to the conventional system, and the interval between refilling the water tank 60 is lengthened, reducing the effort involved.

As shown again in FIGS. 12 and 13, the rib 71, which is integrally provided with the water tray 56, is connected to the water sprinkler 58.
It is divided and formed on a concentric circle with the water sprinkler 58, surrounding the water sprinkler 58 and being higher than the liquid level of the water collected here. Therefore, even if the water surface ripples as the water sprinkler 58 sucks up water collected in the dish 56, the ribs 71 act as a breakwater and do not ripple the inside thereof. Also, since there are no ripples, there is no ripple noise, and no noise leaks outside. The lower end of the water sprinkler 58 inside the rib 71 is always immersed in water, and always sucks up a predetermined amount of water and sprinkles water without uneven watering.

As shown again in FIGS. 17 and 18, the water receptacle flows into the water tank 6 through the dish 56 due to the water sprinkling action of the water sprinkler 58.
When the water in 0 is consumed and the float switch 57 detects that the liquid level is below a predetermined level, a detection signal is sent to the control circuit 93. From here, a signal is sent to the water tank remaining amount lamp 90 on the operation panel 80 to turn it on or blink for a certain period of time.

Alternatively, the alarm buzzer 94 is activated for a certain period of time to notify the user. This allows the user to move the water tank 60 to the main body 3.
16(A) and (C) from the water tank 60. Then, water is supplied into the water tank 60 using the water supply hose 75, and the device is again installed at a predetermined position within the main body 30. This series of operations needs to be done fairly quickly. That is, if the amount of water sprinkled on the water-cooled heat exchanger 53 decreases, the heat exchange efficiency will decrease, leading to the lighting of the abnormality lamp 89 and the stopping of the cooling operation.

If the water tank 60 is quickly replenished with water, there is no need to stop the cooling operation each time, the temperature of the heat exchanged room does not rise, and comfortable air conditioning continues.

Furthermore, if the timer switch 86 is turned on or off without knowing that the amount of water remaining in the water tank 60 is low, the water tank remaining amount lamp 90 will turn on before the set time. Even in such a case, if the water is immediately replenished, the cooling operation will continue, so the timer effect can be ensured.

As shown again in FIG. 16(C), the water supply hose 75 is wound around the hose attachment portion 60a provided along the water tank 60, and both connection portions 75a are connected.

Since the water supply hoses 75b are attached by fitting each other, the storage process of the water supply hose 75 becomes easy. In addition, water tank 60
When supplying water to the above-mentioned connecting portion 75a.

75b are removed from the water tank 60, and one of the connection parts 75b, for example, is removed from the lid body 78 and connected to the water supply port body 77.
, and the other connecting portion 75a may be connected to a water supply source such as a water faucet. That is, the work of supplying water to the water tank 60 can be easily performed.

As shown again in FIG. 11, except when draining the water collected in the dish 56, such as during maintenance, the water receiver is connected to the drain hose 70 at its midpoint, as shown by the two-dot chain line. Bend it upward at a right angle, and insert the tip into the drain hose storage section 66.

The opening at the tip of the water receptacle is raised higher than the water level in the dish 56, so that the water receptacle can collect the water in the dish 56 as it is, making it easy to store the drain hose 70.

When cleaning the inside of the dish 56, the water receptacle is installed on the rear panel 30a by pulling out the drain hose 70 from the drain hose storage section 66.
Extends outward from. The opening at this end allows the water receptacle to be located at a lower level than the bottom surface of the dish 56, allowing all of the collected water to be discharged.

In other words, the water receptacle makes it easy to drain the inside of the dish 56.

As shown again in FIGS. 14 and 15, the integrated air filter 46 is connected to the suction grill 37 on the evaporator 38 side.
and a heat exchange air intake grill 44 on the air-cooled heat exchanger 45 side.
They face each other across both sides, and both filter the air sucked into them. To perform cleaning to prevent clogging,
It can be removed only once from the back panel 30a.

After completing the necessary work, the air filter 46 is reinstalled into the rear panel 30a. At this time, the air filter 46
The lower end of the drain pan 139 slides on and is guided by an air filter guide 74 provided in the drain pan 139. That is, the air filter guide 74 assists in the smooth installation of the air filter 46.

With the air filter 46 attached to a predetermined location, this midway portion is pressed against a predetermined location of the back panel 30a by the air filter guide 74. Therefore, even if there is vibration due to operation, the air filter 46
It does not rattle and prevents chattering noise.

As shown again in FIG. 6, since a fan guard 97 consisting of a plurality of wires 96 is provided on the cold air blowing grille 36, insertion of foreign matter can be prevented.

As shown again in FIGS. 7, 8, and 8, a wire fixing hole 98 is provided in the side wall 36a of the cold air blowing grille 36, and the wire fixing hole 98 is formed by connecting a tapered hole 98a and a hole 98b.
6 can be inserted and fixed securely.

Further, a wire 9 is attached to an end 99a having a large radius of curvature of a wire insertion hole 99 provided in a side wall 36b of the cold air blowing grill 36.
6, it is easy to insert the wire 96. The front end 99b with a small radius of curvature is formed slightly smaller than the diameter of the wire 96, and the wire 96 is forcibly inserted and fixed at the end 99b with a small radius of curvature. It is securely fixed without shifting the position.

In the above embodiment, the flexible discharge hose 64 was inserted into the hole provided in the wall of the heat exchange chamber, but the invention is not limited to this. For example, as shown in FIG. Good too. That is, the window fixture 103 is installed and fixed between the window frame 01 and the sash portion 102a of the window 102,
The discharge hose 64 extending from the air conditioner main body 30 is inserted into the mounting hole 104 provided in the window fixture 103 .

As shown in FIG. 20, the window fixture 103 consists of a pair of left and right mounting plates 105, 105, which can be adapted to the width dimension of the window frame 101 by slidably combining their ends. It has become. mutual mounting plates 105,
The upper end 105a of 105 is bent into a substantially U-shape, and the lower end 105b is bent into a substantially U-shape.

As shown in FIG. 21, the window fixture 103 is placed on the window frame 103 at its lower end 105a which is bent into a substantially U-shape, and is mounted and fixed via a fixing device 106 such as a fixing screw. be done. A window 10 is provided at the upper end portion 105b that is bent into an abbreviated shape.
The second sash portion 102a is mounted and fixed via a fixture 106 such as a fixing screw. That is, the indoor side and lower surfaces of the sash portion 102a are connected to the window fixture 10.
It comes into contact with the side and bottom surface of 3 and is fixed.

Therefore, the sash portion 102a of the window 102 and the window fixture 103 come into contact with each other on two sides, and the installation strength is high. This prevents intrusion and improves sealing performance.

[Effects of the Invention] As explained above, according to the present invention, the vertical dimension of the air outlet of the casing is made narrower than the dimension between both ends of the fan blades, and the width dimension is made extremely larger than the diameter of the fan, so that the air Since it is formed to be slightly narrower than the width of the harmonizer main body, uniform so-called wide air blowing can be performed over the entire surface of the air outlet, resulting in an effect of improving air blowing efficiency.
