Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multipurpose local air conditioner capable of cooling and dehumidifying, which can be easily used without installation work.

[0002]

2. Description of the Related Art A spot air conditioner having an integral structure in which a heat source side unit having a condenser and a use side unit having an evaporator are integrally incorporated in a casing is generally used to cool a person or an object by applying cool air. It is used for the purpose of cooling.
An air conditioner capable of locally blowing is, for example, Japanese Utility Model Publication No. 57-39.
As disclosed in Japanese Patent No. 705, cooling and heating can be performed by using warm air that has passed through the condenser and cold air that has passed through the evaporator.

In this air conditioner, although the function of dehumidifying is fulfilled for the time as a closed room as a whole, since cold air and warm air are separately blown out, the air blower outlet of the cool air and the vicinity of the air outlet are It is not preferable because wind may be blown onto the object to cause dew condensation.

Therefore, Japanese Utility Model Laid-Open No. 1-125932,
As disclosed in Japanese Unexamined Utility Model Publication No. 1-125933, the cool air that has passed through the evaporator is blown out to perform local cooling, and the dry cool air and the hot air that has passed through the condenser are mixed. There is an air conditioner that can be used as a dehumidifier by blowing out to prevent dew condensation and reducing the temperature change in the entire room.

[0005]

In the above air conditioner, an evaporator is arranged in the vicinity of one of the suction ports, and a condenser is arranged in the vicinity of the other of the suction ports. The outlet is opened and closed by a damper device to switch between cooling operation and dehumidifying operation. However, T
The structure does not take into consideration operability and reduction in size and weight so that it can be used easily according to PO.

In view of the above, the present invention has an object to provide an air conditioner having a simple structure that can be used for various purposes such that local cooling and dehumidification can be easily performed at a desired place. To do.

[0007]

A means for solving the problems according to the present invention is, in a housing, a first passage for guiding cold air passing through an evaporator to a first outlet, and a second passage for warm air passing through a condenser. A second passage that leads to the outlet and a damper device that connects the first passage and the second passage for mixing dehumidified cold air and warm air are provided, and the damper device includes the first passage and the second passage. A damper that can be switched between an independent posture that separates the passage and a mixing posture that connects the first passage and the second passage and blocks the passage to the first outlet, and a holding unit that holds the damper in each posture. It consists of

When the damper is switched to the independent posture, the first passage and the second passage become independent from each other, the cold air is blown out from the first outlet, and the warm air is blown out from the second outlet. By orienting the first outlet in the desired direction,
Can perform local cooling. Further, when the damper is switched to the mixing posture, the first passage and the second passage communicate with each other, and the cold air and the warm air dehumidified by the evaporator are mixed and blown out from the second outlet. By selecting this mixed posture,
Can dehumidify indoors and dry clothes.

Therefore, by a simple operation such as switching the damper, it can be used according to the purpose at any place. At this time, since the damper maintains its posture, the posture of the damper does not change even if an external force such as an impact is applied to the housing. Therefore, unintended balloons do not occur, do not cause discomfort, and can be used with confidence.

One side surface of the damper faces the first passage in the independent posture and is formed along the first passage, and the other side surface is
In the mixed posture, the curved surface shape faces the first passage and changes the flow of air toward the second passage. In this way, by forming the shapes of both side surfaces of the damper differently according to the shape of each passage, air can smoothly flow in each posture. Therefore, it is possible to prevent a decrease in wind speed and deliver the wind to a long distance. This allows
Even if the blower is downsized, a sufficient amount of air can be secured and the housing can be downsized.

The damper is rotatably supported around a support shaft, and an operating body for changing the posture is linearly movable on the damper, and the linear movement of the operating body is converted into rotational movement. A transmission mechanism for transmitting to the damper is provided.
The holding means is made of an elastic member that abuts on the operating body and restricts the movement of the operating body, and the elastic member is deformed when a force of a certain amount or more is applied to the operating body and the operation is performed. Allow movement of the body.

Since the posture of the damper can be switched by an operation such as moving the operating body, a complicated operation is not required and it becomes easy to use. Further, the dampers are switched mechanically, so that the structure can be simplified as compared with the case where electric parts such as a motor are used for electric drive.

Condensation occurs on the outer wall of the first passage through which the cool air flows. Therefore, a heat insulating space is formed between the first passage and the housing outer wall. The first passage has a double structure, the outer wall of the first passage is not exposed to the outside, and even if dew condensation occurs, it is only in the heat insulating space, and the dew condensation water does not leak to the outside of the housing.

A suction port is provided on a side surface of the housing, a first blowout port is provided on the other side face, and a second blowout port is provided on an upper surface of the housing. The first blowout port extends from the suction port to the first blowout port. One passage is formed, a second passage is formed from the suction port to the second outlet, and an evaporator in the first passage and a condenser in the second passage are arranged in parallel with the suction port. The structure should be

By sharing the suction port and arranging the evaporator and the condenser in parallel, a part of the first passage and a part of the second passage are formed side by side, and each passage is shortened. Therefore, the housing can be made thinner. Further, the distance between the evaporator and the condenser can be narrowed, and the housing can be made thin and compact.

BEST MODE FOR CARRYING OUT THE INVENTION An air conditioner according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the housing 1 is a vertically long type and has a small depth in the front-rear direction and a compact structure. The second outlets 4 are respectively formed on the upper surface. A drain tank 5 is provided at the lower part of the right side surface so that it can be taken in and out freely, an operation part 6 and a handle 7 for carrying are provided on the upper surface, and casters 8 are attached to the lower surface so that it can be easily moved. .

As shown in FIGS. 5 and 6, the interior of the housing 1 is divided by a partition plate 10 into two upper and lower spaces. As shown in FIGS. 6 and 7, the upper space is partitioned in the front-rear direction by middle partition plates 11 and 12, and an evaporator chamber A and a condenser 14 are provided in which the evaporator 13 is installed in order from the side closer to the back side.
A condenser chamber B in which a second fan 15 is installed
It is referred to as the blower room C. In addition, the lower space is the lower partition plate 1
It is divided in the left and right direction by 6 and has a machine room D and a tank room E.
It is said that

Above the evaporator chamber A and the condenser chamber B, a space defined by an upper partition plate 17 and communicating with the first outlet 2 is formed, and a first blower chamber F containing a first blower 18 is formed. To be done. As shown in FIG. 8, a second blower chamber C is arranged adjacent to the first blower chamber F so as to communicate with the second blower outlet 4. A damper device 20 for connecting the first blower chamber F and the second blower chamber C is provided near the first outlet 2.

The suction port 3 has an evaporator-side opening 3 inside.
a and a condenser side opening 3b, and an evaporator chamber A and a condenser chamber B are arranged facing each opening 3a, 3b. The area of the evaporator side opening 3a is equal to the condenser side opening 3a.
It is assumed to be larger than the area of b. The evaporator chamber A communicates with the suction port 3 and the first blower chamber F, and the evaporator 13 is arranged in parallel with the rear surface of the housing 1 in the vicinity of the evaporator chamber side opening 3 a of the suction port 3. To be done. The indoor air sucked from the suction port 3 is heat-exchanged (cooled / dehumidified) while passing through the evaporator 13, and the dry cold air after passing through the evaporator 13 is
It is sucked into the first blower room F.

In the first blower chamber F, the first blower 18 of the centrifugal fan faces the opening 21 of the upper partition plate 17 communicating with the evaporator chamber A, and is installed horizontally so that the motor is on the upper side. It The first blower 18 is made of a sirocco fan, and the outlet of the casing 22 communicates with the first outlet 2 and
The cold air sucked from below is discharged to the side, and the first outlet 2
From the outside.

The condenser chamber B has a suction port 3 and a second blower chamber C.
And the condenser 14 is arranged in parallel with the rear surface of the evaporator 13 and the housing 1. The indoor air sucked from the condenser side opening 3b of the suction port 3 is heat-exchanged (heated) while passing through the condenser 14, and the hot air after passing through the condenser 14 is the second blower on the front side. It is sucked into chamber C.

In the second blower chamber C, the second blower 15 of the centrifugal fan faces the opening of the partition plate 12 communicating with the condenser chamber B, and the motor is placed vertically so that the motor is located on the condenser chamber side. Is installed in. The second blower 15 is composed of a turbo fan, and the outlet 15a of the casing is directed upward.
It communicates with the air outlet 4. The second blower 15 discharges the warm air sucked from the side upward, and blows it out from the second outlet 4. Here, by arranging the first blower 18 and the second blower 15 separately from each other in the vertical direction, the width of the housing 1 in the front-rear direction can be made smaller than that in the case where the first blower 18 and the second blower 15 are arranged side by side in the horizontal direction.

The middle partition plate 11 for partitioning the evaporator chamber A and the condenser chamber B is erected on the partition plate 10 between the evaporator 13 and the condenser 14, and as shown in FIG. It is inclined so that one side is close to the evaporator 13 and the other side is close to the condenser 14.

The evaporator chamber A becomes a space that widens toward the other side in the left-right direction, and since the opening 21 communicating with the first blower chamber F is formed on the other side of the evaporator chamber A, the suction port 3
The air that has been sucked in from and passed through the evaporator 13 is guided by the intermediate partition plate 11 and smoothly flows toward the other side, improving the blowing efficiency. In the condenser chamber B, the condenser 1
The gap between the partition 4 and the partition plate 11 is wide on one side and narrow on the other side. The condenser side opening 3b of the suction port 3 is formed to be offset to one side, but the sucked air can be efficiently guided from one side to the other side, and the air can be passed over the entire surface of the condenser 14. You can

Therefore, the evaporator 13 and the condenser 14
Even if one air suction port 3 for both is used in common, the flow of each air can be made smooth and the heat exchange efficiency can be improved. Then, the distance between the evaporator 13 and the condenser 14 can be narrowed, and the width in the front-rear direction can be narrowed. Moreover, by sharing the suction port 3, the length of the air passage in the front-rear direction can be shortened. In this way, the housing 1 can be made smaller and thinner.

In the evaporator chamber A, the air cooled by passing through the evaporator 13 becomes cold air and flows toward the other side, and the side plate 25 forming the middle partition plate 11 and the other side of the evaporator chamber A. Since it hits, the dew condensation on the outer surface of the partition plate 11 and the side plate 25,
Water drops adhere. Therefore, the evaporator chamber A has a double structure, and the heat insulating space G is provided between the side plate 25 and the housing 1.
Is formed. By preventing the evaporator chamber A from directly contacting the outer wall of the housing 1, dew condensation on the outer wall of the housing 1 can be prevented.

In the machine room D, refrigeration equipment such as the compressor 27 and electric components (not shown) are installed. The drain chamber 5 is housed in the tank chamber E so that it can be taken in and out from the outside. The partition plate 10 is provided with a discharge port 28 for discharging drainage from the evaporator 13 and the condenser 14 and water droplets that have condensed and dropped to the drain tank 5, and is provided with a valve mechanism 29 for opening and closing the discharge port 28. There is. The valve mechanism 29 opens and closes the discharge port 28 in conjunction with the withdrawal of the drain tank 5.

In the air conditioner having the above structure,
As shown in FIG. 9, two air passages are formed. The first passage H is defined as the evaporator-side opening 3a of the suction port 3 → the evaporator 13 → the first blower 18 → the first blowout port 2 and blows out the dry cold air. The second passage I includes the condenser-side opening 3b of the suction port 3 → the condenser 14 → the second blower 15 → the second outlet 4
It is said that hot air is blown out.

Then, as shown in FIG. 10, the first passage H
The second passage I and the second passage I are joined together by a damper device 20. The air that has passed through the evaporator 13 in the first passage H and the air that has passed through the condenser 14 in the second passage I are mixed and blown out from the second outlet 4, thereby lowering the temperature of warm air and drying. The breeze can be blown indoors.

The damper device 20 comprises a switchable damper 30 for restricting the flow of air, an operating body 31 for switching the damper 30, and an elastic member 32 for holding and fixing the operating body 31. The damper 30 has an independent posture that partitions the passage by blocking the branch opening 33 between the first passage H and the second passage I shown in FIG. 8 and the first passage H opened by opening the branch opening 33 shown in FIG. And the second passage I are communicated with each other to switch to a mixing posture in which the passage to the first outlet 2 is blocked.

The damper 30 has a support shaft 34 attached to the upper partition plate 17.
It is rotatably supported by, and the front and back sides have different shapes. That is, the damper 30 becomes a part of the wall surface of the first passage H in the independent posture, and one side surface 30a of the damper 30 facing the first passage H is a flat surface and is continuous with the casing 22 of the first blower 18. The shape is along the first passage H. The other side surface 30b opposite to the one side surface 30a is a curved surface, and changes the flow of the cool air discharged from the first blower 18 in the mixing posture to change the branch port 33.
To the second passage I. In this way, by making the shape of the damper 30 different depending on its posture, the air flow can be made smooth.

As shown in FIGS. 12 and 13, the operating body 31 is supported on the upper surface of the casing 22 of the first blower 18 so as to be movable in the left-right direction. The operation body 31 is connected to the damper 30 via the pin 35. The posture is switched by rotating the damper 30 in conjunction with the movement of the operation body 31. The pin 35 is provided on the upper surface of the damper 30 and penetrates the circular arc groove 36 formed on the casing 22 to form a substantially elongated concave groove 3 formed on the lower surface of the operating body 31.
7 is engaged. The linear movement of the operating body 31 is converted into rotational movement and transmitted to the damper 30 by the transmission mechanism including the pins 35 and the grooves 36 and 37.

A knob 38 is projectingly provided on the upper surface of the operating body 31, and the knob 38 is exposed to the outside through a lateral hole formed in the operating portion 6 on the upper surface of the housing 1. By operating the knob 38 to move the operating body 31 left and right, the posture of the damper 30 is switched.

The elastic member 32 contacts the operating body 31,
By restricting its movement, the damper 30 is held in each posture, and it is a leaf spring long in the left-right direction and is arranged so as to face the operating body 31. Both ends of the elastic member 32 are locked to the casing 22, and a locking portion 39 that is curved in a semicircular shape toward the operating body 31 is formed to project in the central portion. A convex portion 40 is formed in the vicinity of the center of the side surface of the operating body 31, and when the convex portion 40 contacts the locking portion 39, the movement of the operating body 31 is restricted. Then, when the locking portion 39 is strongly pushed by the operating body 31, the elastic member 32 is elastically deformed and bent, and the convex portion 40 can move over the locking portion 39 and move, and the posture of the damper 30 can be switched. .

In the air conditioner having the above structure, the cool dry operation is started by the switch of the operation section 6. In the cool dry operation, the knob 38 is operated to operate the operation body 3
When 1 is moved to the right position, the damper 30 becomes an independent posture. As shown in FIG. 9, from the evaporator 13 to the first blower 1
The first passage H leading to the first outlet 2 via 8 and the condenser 1
No. 4 through the second blower 15 to the second outlet 4
The passage I is reliably separated.

The room air sucked from the suction port 3 is heat-exchanged by the evaporator 13, and the cooled and dehumidified air is supplied to the room from the first outlet 2. The drain water generated by the dehumidification drops downward from the evaporator 13, and the drain tank 5
Stored in. Further, a part of the indoor air sucked from the suction port 3 is heat-exchanged by the condenser 14, and the heated air is discharged from the second outlet 4 toward the lower part of the room. By moving the housing 1 and changing the blowing direction of the first outlet 2, cold air can be blown in a desired direction, and local cooling can be easily performed.

Further, as shown in FIG. 10, when it is desired not to blow the cooled air from the first outlet 2, that is, to give priority to the dry function, the cold air in the first passage H and the temperature in the second passage I are cooled. The wind is mixed and blown out from the second outlet 4. By operating the knob 38, the operating body 31 is moved to the left position, and the damper 30 is switched to the mixing posture. Then, the passage of the first passage H to the first outlet 2 is blocked, the branch port 33 is opened, and the first passage H communicates with the second passage I.

The air that has been heat-exchanged and cooled and dehumidified in the evaporator 13 changes its flow along the other side surface 30b of the curved shape of the damper 30 via the first blower 18 and flows into the second passage I. The dry cool air is mixed with the warm air flowing through the second passage H, and the dry air having an appropriate temperature is discharged from the second outlet 4 upward in the room and spreads inside the room. Therefore, it is possible to dehumidify without lowering the indoor temperature.

In this way, the blowing direction can be easily changed only by operating the knob 38 to perform local cooling or dehumidification. Here, the movement of the damper device 20 at the time of switching will be described. For example, when the damper 30 is switched from the independent posture to the mixed posture, the knob 38 is moved from right to left. The damper 3 is moved along with the movement of the operating body 31.
The 0 pin 35 moves along the concave groove 37 of the operating body 31 and the circular arc groove 36 of the casing 22 while drawing a circular arc from the rear surface side to the front surface side. The damper 30 rotates in the clockwise direction around the support shaft 34 to open the branch port 33 and block the passage to the first outlet port 2.

When the damper 30 is in each posture, the convex portion 40 of the operating body 31 is in contact with the base of the locking portion 39 of the elastic member 32, and the movement of the operating body 31 in one direction is restricted. It Moreover, since the pin 35 of the damper 30 is located at each end of the concave groove 37 and the circular arc groove 36,
Movement of the operating body 31 in the other direction is restricted. Operating body 31
Is restricted from moving in either the left or right direction, and the operating body 31 cannot be moved unless force is applied to the knob 38, and the posture of the damper 30 is maintained. Therefore, even if an external force such as an impact is applied to the housing 1, the operation body 31 does not move, and the damper 30
Does not change its attitude.

In order to switch the posture of the damper 30 from this state, for example, the knob 38 is moved from left to right while applying a certain force or more. As the convex portion 40 of the operating body 31 slides from the root side of the locking portion 39 of the elastic member 32 to the top, the elastic member 32 is pushed to the side opposite to the operating body 31, and the convex portion 40 is locked. The operating body 31 moves over the portion 39. When the knob 38 reaches the right end, the elastic member 32 returns to its original position due to the elastic force, and the convex portion 40 of the operating body 31 is positioned at the base of the locking portion 39 of the elastic member 32. The operating body 31 is fixed in this state, and the damper 30 is held in an independent posture.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention. The operating body is not limited to the slide type, but may be a rotary type and adapted to the movement of the rotating damper. Further, the amount of movement of the damper may be adjustable so that the amount of air blown from each of the air outlets can be varied.

[0043]

As is apparent from the above description, according to the present invention, an air conditioner can be realized which can switch between local cooling and dehumidification with a simple operation and can be easily used according to TPO. . Also, even if external force such as impact is applied to the housing, the position of the damper is maintained,
There is no fear that the air flow will change, and you can use it comfortably without any trouble. Moreover, considering the arrangement of the evaporator and the condenser, forming the two passages makes it possible to make the housing compact and easily move it, so that it can be used in a familiar place.
