Description

  The present invention relates to a structure in which an integrated air conditioner having a refrigeration cycle is provided with a function of a dedicated cold air machine and a function of a dedicated dehumidifying machine.

  A compressor, a condenser, a decompressor, and an evaporator are provided in the frame to constitute a refrigeration cycle. Air cooled by the cold air fan through the evaporator is blown out from the cold air outlet and passed through the condenser by the hot air fan. There is known a cold air blower configured to blow out heated air from a hot air outlet.

  The cool air blower is also used as a dehumidifier by utilizing the dehumidification function that exists as a refrigeration cycle, but its dehumidifying capacity is lower than that of a dehumidifier, so it has traditionally not been used as a full-scale dehumidifier. It was not suitable. Therefore, recently, there is a demand to use the cold air fan as a full-scale dehumidifier, and it has a bypass channel that connects the discharge port of the cold air fan and the air intake port of the hot air fan, and can switch the direction of the cold air blowing. When used as a dehumidifier, it is possible to improve the efficiency of the refrigeration cycle by sending cool air that has passed through the evaporator to the condenser to improve the efficiency of the refrigeration cycle, and to obtain a dehumidifying capacity comparable to that of a dedicated dehumidifier did it.

In addition, since the cooling air capacity of the cooling air fan increases as the cooling efficiency of the refrigerant of the condenser increases, the cooling water efficiency is improved by spraying the drain water generated by the evaporator into the condenser and cooling the condenser with the drain water. This function allows the drain water to evaporate due to the heat of the condenser, so that the amount of drain water can be reduced. However, in this case, the dehumidifying function is sacrificed, so that it is not suitable for dehumidifying the room. For this reason, the drain pan in the frame is equipped with two drainage channels that look into the condenser and drain tank, and the drainage drainage channel can be arbitrarily changed between the condenser side and the drain tank side. There is one that can switch only the operation.

  By providing the above-mentioned two functions in the frame body, it is possible to realize a combined use of a cold air blower and a dehumidifier. However, in order to share these two functions, the operation means for switching the blowing direction of the cold wind and the drain water drainage are switched. When each of the operation means is configured, there is a possibility of selecting the drain side on the condenser side when the dehumidifying operation is selected, and the moisture dehumidified by the evaporator will evaporate in the condenser. Decreases and the function as a dedicated dehumidifier cannot be exhibited.

  For this reason, the operation means for switching the blowing direction of the cold air and the operation means for switching the drain water drainage channel are interlocked, and the drain water drainage channel operating means is forcibly positioned on the drain tank side during the dehumidifying operation, On the other hand, when the drain side on the condenser side is selected, it is necessary to prevent the misuse by adopting a configuration for forcibly switching to the cold air operation. However, the configuration in which these operations are performed by two operation means has a drawback that the operation switching operation becomes complicated and the operation state becomes difficult to understand.

  In addition, since the operation means is securely held at the switching position in order to surely switch the operation, a large operating force is required when operating the operation means. When the other operating means is driven simultaneously with the operation, a large force is required, and there is a problem in terms of operability.

  The present invention solves the above-described problems. In a frame 1 of an air conditioner, a compressor 2 for compressing a refrigerant, a capacitor 3 to which a high-temperature gaseous refrigerant is sent, and a liquefied refrigerant are decompressed. 4, an evaporator 5 that is sent via 4 is provided, and a refrigerant that is vaporized by the evaporator 5 constitutes a refrigeration cycle that is returned to the compressor 2, and a hot air fan 3 a that blows air to the condenser 3 and cold air that blows air to the evaporator 5. In the air conditioner in which the drain pan 6 is disposed below the evaporator 5 and the condenser 3 and the drain tank 7 are disposed below the drain pan 6, a cool air blow provided in the frame body 1 is provided. A bypass passage 10 communicating with the air intake 9 of the hot air fan 3a is attached to the fan case 5b of the cold air fan 5a connected to the outlet 8, and the fan case 5b and the fan case 5b are connected to the fan case 5b. The connection port 11 with the path flow path 10 is provided with a blowing path switching means for changing the blowing direction of the cold air between the cold air outlet 8 and the bypass flow path 10, and the drain pan 6 is generated by the evaporator 5. The lower drainage channel 6a for guiding the drain water to the drain tank 7, the upper drainage channel 6b for guiding it to the condenser 3, and the drainage channel for changing the drainage direction of the drain water between the lower drainage channel 6a and the upper drainage channel 6b Switching means, and the ventilation path switching means and the drainage path switching means are attached to the operating means 14 provided on the side surface of the frame 1, and the ventilation path switching means and the drainage path switching means driven by this one operating means 14. The drainage path switching means selects the lower drainage path 6a when the ventilation path switching means opens the connection port 11, and the drainage path switching means closes the lower drainage when the ventilation path switching means closes the connection port 11. It is characterized in that the road 6a and the upper drain passage 6b arranged so as to arbitrarily selected.

  Further, the connection port 11 is disposed on the side surface of the fan case 5b of the cold air fan 5a, and a closing plate 12 that is driven by the operation means 14 to open and close the connection port 11, and an open / close switch 15 that detects opening and closing of the connection port 11. And an opening / closing means 13 for opening and closing the cold air outlet 8 in response to a signal from the opening / closing switch 15. When the closing plate 12 opens the connection port 11, the opening / closing means 13 closes the cold air outlet 8 and closes the connection port 11. Sometimes the opening / closing means 13 opens the cold air outlet 8, and the drain pan 6 is provided with a communication hole 6 c communicating between the lower drainage path 6 a and the upper drainage path 6 b, and the movable end of the closing means 12 communicates with the movable end. An opening / closing valve 12a for opening and closing the hole 6c is provided. When the closing plate 12 opens the connection port 11, the opening / closing valve 12a opens the communication hole 6c to select the lower drainage channel 6a, and when the connection port 11 is closed, the opening / closing valve 12 is provided. Is driven between a first closing position for opening the communication hole 6c and a second closing position for closing the communication hole 6c, so that the lower drainage path 6a and the upper drainage path 6b can be switched. Only the opening / closing operation of the closing plate 12 is performed by the operation means 14, so that the operation can be switched, and the operability of the operation means 14 can be improved.

  Further, a louver 16 is movably attached to the cold air outlet 8, and the louver 16 is provided with the cold air outlet 8 so as to be openable and closable to constitute the opening / closing means 13. When the connection port 11 is opened, the louver 16 is cooled by the louver 16. The air outlet 8 is closed, and the louver 16 can also serve as the opening / closing means 13.

  The connection port 11 is disposed at the lower side of the fan case 5b, the bypass channel 10 is formed in a space between the frame 1 and the fan case 5b, and the closing plate 12 is laterally inserted into the space. It is slidably attached, and the parts can be efficiently arranged using the space between the frame 1 and the lower side of the fan case 5b.

  Further, since the caster 19 is provided on the bottom surface of the frame 1 and at least the rotation direction of the caster 19 on the side where the operation means 14 is arranged is arranged in a direction different from the drive direction of the operation means 14, the operation means 14 is arranged. Even in the configuration in which the slide operation is performed in the lateral direction, the product does not easily move when the operation means 14 is operated.

  In the air conditioner according to the present invention, the cold air that has passed through the evaporator 5 is blown out from the cold air outlet 8 in normal cold air operation, and the cold air that has passed through the evaporator 5 is sent to the condenser 3 as a full-scale dehumidifier. In addition to being usable as a cold air blower, the drain water that is normally sent to the drain tank 7 is sent to the condenser 3 to enable the operation that improves the refrigeration cycle and reduces the amount of drain water.

  And when the ventilation path switching means which changes the blowing direction of cold air and the drainage path switching means which changes the drainage direction of drain water are attached to one operation means 14, and the ventilation path switching means closes the connection port 11 Only the lower drainage path 6a and the upper drainage path 6b can be selected by the drainage path switching means, and the drainage path switching means always selects the lower drainage path 6a when the blowing path switching means opens the connection port 11. Since the configuration is adopted, it is possible to prevent an erroneous operation by the user, and it is possible to perform the operation switching by the single operation means 14, so that the operation switching operation is simplified and the usability can be improved.

  Further, a closing plate 12 for opening and closing the connection port 11 and an opening and closing means 13 for opening and closing the cold air outlet 8 are provided, and the opening and closing means 13 that is operated by a signal of an opening and closing switch 15 that detects the opening and closing of the connection port 11 includes: When the connection port 11 is opened, the cold air outlet 8 is closed, and when the connection port 11 is closed, the cold air outlet 8 is opened to switch the direction of blowing the cold air, and when the connection port 11 is opened, it is provided at the movable end of the closing plate 12. When the closing valve 12a opens the communication hole 6c to select the lower drainage channel 6a and the connection port 11 is closed, the on-off valve 12a opens the communication hole 6c at the first closed position and communicates at the second closed position. The hole 6c is closed so that the lower drainage channel 6a and the upper drainage channel 6b can be selected, and the operation of the air conditioner can be switched by switching the position of the operating means 14 formed in the closing means 12. Because it became With switching operation of the converter is simple, easily becomes what can confirm the operation in switching position of the operating means 14, could be improved usability.

  Further, when the opening / closing means 13 is configured to open and close the cold air outlet 5c with the louver 16 attached so that the cold air outlet 8 can be opened and closed, the operating state of the cold air / dehumidification depends on the switching position of the operating means 14 and the opening / closing of the louver 16. In addition to being easy to confirm, the louver 16 also serves as the opening / closing means 13, whereby an increase in the number of parts and an increase in cost can be suppressed.

  In addition, a space is formed in the lower part of the side surface of the fan case 5b of the cool air fan 5a in the frame 1, and this space has conventionally been a wasteful space, but in the present invention, this space is used to bypass the flow. Since the path 10 and the closing plate 12 of the air path switching means are disposed, the components can be efficiently disposed in the frame body 1 and can be realized without increasing the shape of the frame body 1.

  When the operation means 14 is slid in the horizontal direction, the caster 19 attached to the bottom surface of the frame 1 is turned in a direction different from the slide direction of the operation means 14, so that the caster 19 is operated when the operation means 14 is operated. Therefore, even if the operation means 14 is operated in the horizontal direction, the product can be easily operated without moving.

Reference numeral 3b denotes a fan case that covers the outer periphery of the hot air fan 3a. The air that has passed through the condenser 3 and has reached a high temperature is guided to the hot air outlet 3c by the fan case 3b and is discharged from the hot air outlet 18.

  Reference numeral 8 denotes a cold air outlet provided in the upper front portion of the frame 1, and 5 c denotes a cold air outlet of a cold air fan 5 a continuous to the cold air outlet 8. The liquid refrigerant decompressed by the decompressor 4 is sent to the evaporator 5.

Reference numeral 5b denotes a fan case that covers the outer periphery of the cold air fan 5a, and air that has passed through the evaporator 5 and has become low temperature is guided to the cold air outlet 5c by the fan case 5b and blown out from the cold air outlet 8.

  6 is a drain pan provided below the evaporator 5, 7 is a drain tank provided in the lower part of the frame 1, 1 a is a tank outlet located on the side of the drain tank 7, and is used for air cooled by the evaporator 5. The contained water is condensed on the surface of the evaporator 5 to form drain water and is dripped onto the drain pan 6. The drain water dripped onto the drain pan 6 is accumulated in the drain tank 7, and the drain tank 7 opens the tank outlet 1a and is taken out from the frame 1 and discarded.

  Reference numeral 19 denotes a caster attached to the bottom plate of the frame 1, and an integrated air conditioner such as a cool air blower or a dehumidifier is used by moving to an arbitrary place. Therefore, when moving the air conditioner, the air conditioner Even if the machine is not lifted, it can be easily moved by the caster 19 and the convenience of handling is improved.

  In the embodiment shown in FIG. 1, 9 is an air intake port of the hot air fan 3a that allows air to pass through the condenser 3, 10 is a bypass flow path that connects the fan case 5b of the cold air fan 5a and the air intake port 9, and 11 is The connection port 10a between the fan case 5b and the bypass flow path 10 is an outlet of the bypass flow path 10 that opens to the flow path from the air intake 9 to the condenser 3, and passes through the evaporator 5 in the frame 1. Blowing path switching means for switching the cold air blowing direction between the cold air outlet 8 side and the bypass flow path 10 side is provided.

  In this configuration, when the cooling air outlet 5c of the cold air fan 5a is opened by the air blowing path switching means and the connection port 11 is closed, the cold air that has passed through the evaporator 5 by the air blowing fan 5a is guided to the cold air outlet 5c and is cooled. It blows out into the room from the wind outlet 8 and can be used as a cold wind machine.

  On the other hand, when the cooling air outlet 5c of the cold air fan 5a is closed and the connection port 11 is opened by the air blowing path switching means, the cold air that has passed through the evaporator 5 by the air blowing fan 5a is guided to the bypass flow passage 10 and is bypassed. It flows between the air inlet 9 and the condenser 3 from the outlet 10a of the passage 10, and is mixed with the room air taken in from the air inlet 9 by the blower fan 3a and sent to the condenser 3. Since the low-temperature air cooled by the evaporator 5 is allowed to pass through the cooling air to the cooling air from the cold air outlet 8 and the refrigerant sent to the condenser 3 can be efficiently cooled, a dedicated high dehumidifying ability Can be used as a dehumidifier.

  A condenser 3 is disposed below the drain pan 6, a drain tank 7 is disposed below the condenser 3, 6 a is a lower drainage channel that guides drain water from the drain pan 6 to the drain tank 7, and 6 b is a drain pan 6. The drain pan 6 is provided with drain path switching means for switching the drain water drain direction between the lower drain path 6a and the upper drain path 6b.

  In this configuration, when the lower drainage channel 6a is opened by the drainage channel switching means and the upper drainage channel 6b is closed, the drain water generated by the evaporator 5 and dripped onto the drain pan 6 is discharged from the lower drainage channel 6a to the drain tank. 7, all drain water generated in the evaporator 5 is accumulated in the drain tank 7, and the indoor air can be dehumidified.

  On the other hand, when the upper drainage channel 6b is opened by the drainage channel switching means and the lower drainage channel 6a is opened, the drain water that has dropped on the drain pan 6 is guided from the upper drainage channel 6b to the capacitor 3, so that the capacitor 3 The refrigerant cooled by the drain water and efficiently sent to the condenser 3 can be efficiently cooled, and the drain water evaporates by the heat of the condenser 3, so that it is possible to improve the cold air capacity and reduce the amount of the drain water. . In this operation mode, the moisture in the air dehumidified by the evaporator 5 evaporates by the condenser 3, so that dehumidification in the room is not performed, but cold air operation with improved cold air capability becomes possible.

  If the air conditioner satisfying both cold air and dehumidifying performance can be realized by providing both the cold air blowing direction and the drain water draining direction in the frame 1, the added value that can be used throughout the year. Although a high air conditioner can be provided, in the method of operating these two selection functions, the treatment of drain water when used as a dehumidifier becomes a problem. For this reason, it is necessary to link the selection function of the cold air blowing direction and the drain water draining direction that are respectively operated, but the method of operating the two selection functions complicates the switching operation and makes it difficult to understand the operating state. There were drawbacks.

  In the present invention, the two selection functions can be operated at the same time so as to realize a structure that simplifies operability and facilitates confirmation of the operation state. In the embodiment shown in FIG. The connection port 11 is disposed on the side surface of the fan case 5b of the blower fan 5a, 12 is a closing plate attached to the connection port 11 so as to be slidable, and 14 is an operation means constituted by an operation knob attached to the closing plate 12. The connection plate 11 can be opened and closed by directly driving the closing plate 12 by operating the operation means 14.

  13 is an opening / closing means provided movably at the cold air outlet 8, 15 is an opening / closing switch for detecting opening / closing of the connection port 11 by the closing plate 12, 12b is a switch operating portion provided on the closing plate 12, and the opening / closing means 13 is The cool air outlet 8 is opened and closed by being driven by a driving means such as a motor or a solenoid (not shown). When the closing plate 12 closes the connection port 11, the opening / closing means 13 opens the cold air outlet 8, and when the closing plate 12 opens the connection port 11, the switch operating portion 12 b of the closing plate 12 is an opening / closing switch. 15 is switched and the opening / closing means 13 is driven to close the cold air outlet 8.

  12a is a closing valve attached to the movable end of the closing plate 12, 6d is a partition plate that partitions the lower drainage channel 6a and the upper drainage channel 6b of the drain pan 6, and 6c is a lower drainage channel 6a that is partitioned by the partition plate 6d and the upper part When the drainage port of the upper drainage channel 6b is arranged at a position higher than the drainage port of the lower drainage channel 6a and the shutoff valve 12a opens the communication hole 6c. The drain water dripped from the evaporator 5 flows into the lower drainage channel 6a through the communication hole 6c, and when the shutoff valve 13a closes the communication hole 6c, the water level of the drain pan 6 rises to the upper drainage channel 6b side. Flows in.

  FIG. 1 shows a state in which the operating means 14 is set at the dehumidifying cold air operating position. At the position of the operating means 14, the closing plate 12 is driven to the first closing position to close the connection port 11. At the position, the shut-off valve 12a opens the communication hole 6c, and the opening / closing means 13 opens the cold air outlet 5c. Water is sent to the drain tank 7 from the lower drainage channel 6a, and indoor cold air and dehumidification can be performed.

  FIG. 2 shows a state in which the operating means 14 is set at the dehumidifying operation position. In this position, the closing plate 12 and the closing valve 12a are driven in the direction opposite to the drain pan 6, and the connection port 11 and the communication hole 6c are opened. Since the opening / closing switch 15 is switched by the switch operating portion 12b of the closing plate 12 and the opening / closing means 13 closes the cold air outlet 5c, the cold air having passed through the evaporator 5 is sent from the connection port 11 to the bypass passage 10 and is supplied to the air intake port. The drain water mixed with the indoor air taken in from 9 and sent to the condenser 3 and dropped onto the drain pan 6 from the evaporator 5 is sent to the drain tank 7 from the lower drainage channel 6a, so that the room can be dehumidified.

  FIG. 3 shows a state in which the operating means 14 is set at the cold air operation position. In this position, the closing plate 12 and the closing valve 12a are driven in the direction of the drain pan 6 to be driven to the second closing position, and the connection port 11 is connected. Since the communication hole 6c is closed and the on-off valve 13 opens the cold air outlet 5c, the cold air that has passed through the evaporator 5 is blown from the cold air outlet 8, and the drain water that has fallen from the evaporator 5 to the drain pan 6 is the upper drainage channel. It is sent to the condenser 3 from 6b, and it is possible to improve the cold air capacity and perform the cold air operation with the drain saving.

  As described above, the drain water drainage path can be selected by the closing valve 12a only when the connection port 11 is closed by the closing plate 12, and the dehumidifying operation is selected and the closing plate 12 opens the connection port 11. Since the stop valve 12a always opens the communication hole 6c when opened, it is possible to reliably prevent misuse when the dehumidifying operation is selected.

  When operating means are provided for each of the air flow path switching means and the drainage path switching means as in the prior art, it is necessary to check the operation state by looking at the positional relationship between the operation means. However, in this invention, the user can select the operation by switching operation of one operation means 14 and can easily change the operation state depending on the position of the operation means 14. Since it can be confirmed, the user only has to set the operating means 14 to the desired driving position, and the switching operation of the driving and the checking of the driving state can be performed very easily, and the usability can be improved. .

  In addition, when each of the operation means is provided in the air supply path switching means and the drainage path switching means, a structure for restricting the position of each other operation means is necessary to prevent misuse, and the two operation means are operated simultaneously. However, in the product in which the caster 19 is attached, the main body moves and the operation is difficult to perform. However, in the present invention, only one operation means 14 is operated. Since the operating means 14 only drives the closing plate 12, it is possible to operate with a very light operating force, and the operability can be improved without moving the main body even with a product to which the caster 19 is attached.

  Reference numeral 16 denotes a louver movably attached to the cold air outlet 8. In the embodiment of the present invention, the cold air blowing direction can be arbitrarily changed by the louver 16 during the cold air operation. When 14 is set to the dehumidifying operation position, the open / close switch 15 is operated by the switch operating portion 12b of the closing plate 12, the louver 16 is driven to close the cold air outlet 8, and the cold air outlet 5c is blocked by the louver 16. Can be done. For this reason, the louver 16 can also be used as the opening / closing means 13 to suppress the increase in the number of parts, and when the user selects the dehumidifying operation, the user can confirm the operation switching by driving the louver 16. When 16 is closed, it can be easily confirmed that the dehumidifying operation is being performed, and the operation state can be easily confirmed.

  By the way, in the air conditioner equipped with the casters 19, it is more effective to prevent the product from moving during operation of the operation means 14 when the operation means 14 is slidably attached in the vertical direction, but the fan case 5b. Since a space for disposing the closing plate 12 and the bypass flow path 10 is required between the frame body 1 and the frame body 1, the shape of the frame body 1 becomes large. On the other hand, since the fan case 5b of the blower fan 5a is curved at the lower side, a space is formed at the lower side of the fan case 5b in the frame 1, and nothing has been placed in this space in the past. It was a dead space.

  In the present invention, the connection port 11 is arranged at the lower side of the side surface of the fan case 5b, the bypass channel 10 is formed using the space between the frame body 1 and the fan case 5b, and the closing plate 12 is placed in this space. Is slidable horizontally. By arranging the bypass flow path 10 and the closing plate 12 in the space in the frame 1 that has become a dead space in this way, the arrangement efficiency of the components in the frame 1 is improved. It can be realized without changing.

  Further, when the operation unit 14 is configured to slide in the horizontal direction as described above, there is a concern that the main body may move when the operation unit 14 is operated. In the present invention, the frame body in which the operation unit 14 is disposed. Since the caster 19 is attached so that the side surface of 1 is moved in the front-rear direction, the rotation direction of the caster 19 is different from the sliding direction of the operation means 14, and the operation means 14 can be operated with a light force. Even if a lateral force is applied to the product during operation of the operation means 14, the caster 19 does not rotate, and even if the operation means 14 is slid in the lateral direction, the product is not moved when the operation means 14 is operated. It became possible to operate.
