Description

TECHNICAL FIELD

[0001] The present invention relates to an air conditioning apparatus, and more particularly, to an air conditioning apparatus of a dual mode operation mode, which can selectively implement the use of an outdoor unit and an indoor unit in combination or separately according to the physical environment of a space requiring cooling, can not only obtain a stable cooling capacity by supplementing a refrigerant, but also can rapidly discharge condensed water generated in a cooling process to the outside through the outdoor unit. BACKGROUND

[0002] An air conditioner is a device that condenses a refrigerant in a gaseous state into a liquid state, and then restores it to a gaseous state inside an evaporator and performs heat exchange with the surrounding air to appropriately adjust the temperature and humidity of air in a specific space, and in particular, has been a necessity for residential or office spaces in summer with high temperature and humidity, and its demand has been increasing with global warming in recent years.

[0003] Generally, such an air conditioner is composed of an indoor unit located in an indoor space and performing heat exchange between indoor air and a refrigerant, and an outdoor unit located in an outdoor space and performing heat exchange between outdoor air and a refrigerant, and is classified into a separate type and a unitary type according to whether the indoor unit and the outdoor unit are configured in an integrated structure.

[0004] Although the former separate type has excellent cooling capacity, it is difficult to install because both the indoor unit and the outdoor unit need a relatively large volume in order to fully exhibit such an advantage. In contrast, although the latter unitary type has relatively weak cooling capacity compared to the former, it is very convenient to install because it is configured in a small structure in terms of structural characteristics.

[0005] Thus, the air conditioner configured in a unitary structure of the indoor unit and the outdoor unit is widely used in small spaces or simple facilities, etc. However, even though the air conditioner configured in a unitary structure is a small structure, it is not only difficult to use in a state of being installed in a fixed building, but also difficult for a user to easily carry and use in a desired place due to the relatively heavy characteristics of the outdoor unit assembly.

[0006] For this reason, as shown in an example of Figure 11 , various technologies for greatly reducing the overall weight and compactly arranging the assembly to improve the portability of a user are disclosed. However, technologies including Figure 11 have a problem in that the cooling efficiency is reduced because most of the currently disclosed technologies configure the indoor unit and the outdoor unit in a unitary structure and perform heat exchange between the outdoor unit and a cooling object through the air in the indoor space. SUMMARY

The housing body 13 can be integrally formed with the outdoor unit body 11, and a plurality of second external air suction holes 133 are formed in the left and right side portions thereof.

[0041] In this case, as shown in Figure 6 , the present application does not exclude the case where the upper portion of the housing body 13 is formed in an open structure. The housing body 13 is a portion into which the indoor unit portion 20 is inserted, as shown in Figure 2a , if the housing body 13 is formed in a passage structure, the indoor unit portion 20 can be slidably inserted or separated in the front and rear directions, as shown in Figure 6 , if formed in a structure in which the upper portion is open, the indoor unit portion 20 can be inserted and separated in the front and rear directions or the up and down directions as shown in the drawing.

[0042] The outdoor unit connector 15 is formed to protrude from the center portion of the partition 132 in the interior of the housing body 13 in the rear direction. In this case, the outdoor unit connector 15 can be formed in a structure in which a first outdoor unit refrigerant connection portion 151, a second outdoor unit refrigerant connection portion 153, an outdoor unit drain pipe connection portion 155, and an outdoor unit electric wire connection portion 157 are provided.

[0044] The compressor 12 is a portion that compresses refrigerant, and is provided in the interior front portion of the outdoor unit body 11. The compressor 12 is connected to the second outdoor unit refrigerant connection portion 153 through a connection pipe 154. The condenser 14, which is connected to the compressor 12, is a portion that cools the refrigerant compressed by the compressor 12 through high-pressure steam to change it into a liquid, and is provided in the interior rear portion of the outdoor unit body 11 at a predetermined interval from the first external air suction hole 111.

[0045] The outdoor unit blower fan 16 is a portion that discharges heated air, which is generated in the compression process, to the outside after being sucked through the first external air suction hole 111, and is provided in the interior rear portion of the outdoor unit body 11 at a predetermined interval from the heated air discharge hole 113.

[0046] The indoor unit portion 20 is a portion that is connected to the outdoor unit portion 10 and performs refrigeration on a specific space, as shown in Figure 2a andFigure 5 As shown, the indoor unit 20 can include an indoor unit body 21, an operation panel 23, an evaporator 22, an indoor unit blower fan 24, and an indoor unit connector 25.

[0047] The indoor unit body 21 is internally formed with a receiving space of a prescribed size, and is formed with a plurality of indoor unit suction holes 211 at left and right side portions, and a cooling air discharge hole 213 at an upper side portion of a front surface. Preferably, the indoor unit suction holes 211 are in communication with the second outdoor unit external air suction hole 133 of the outdoor unit portion 10, and the indoor unit body 21 is formed in a shape corresponding to the shape of the internal space of the receiving body 13.

[0048] The operation panel 23 refers to a portion for controlling the operation of the indoor unit portion 20, and is provided at a lower side portion of the front surface of the indoor unit body 21. A power source, an air volume adjustment, a temperature adjustment, and the like, which are related to the operation of a general air conditioning device, can be provided as control buttons or control switches on the operation panel 23, and such buttons or switches can also be implemented in a touch screen manner.

[0049] The evaporator 22 is spaced apart from one of the indoor unit suction holes 211 by a prescribed interval, and is provided at one side portion of the internal space of the indoor unit body 21, and is connected to the first indoor unit refrigerant connection portion 251 described later. An expansion valve, not shown, is provided at the evaporator 22. The indoor unit blower fan 24 is provided at the other side portion of the internal space of the indoor unit body 21, and can discharge air, which has been cooled after flowing in through the indoor unit suction holes 211, through the cooling air discharge hole 213.

[0050] The indoor unit connector 25 is formed to protrude from a central portion of the rear surface of the indoor unit body 21. In this case, similarly to the outdoor unit connector 15, the first indoor unit refrigerant connection portion 251, the second indoor unit refrigerant connection portion 253, the indoor unit drain pipe connection portion 255, and the indoor unit electric wire connection portion 257 are provided at the indoor unit connector 25. The first indoor unit refrigerant connection portion 251 and the second indoor unit refrigerant connection portion 253 correspond to the first outdoor unit refrigerant connection portion 151 and the second outdoor unit refrigerant connection portion 153, respectively, the indoor unit drain pipe connection portion 255 corresponds to the outdoor unit drain pipe connection portion 155, and the indoor unit electric wire connection portion 257 corresponds to the outdoor unit electric wire connection portion 157.

[0051] On the other hand, as shown in FIG. 2, the operation panel 23 of the indoor unit portion 20 can be provided at a central portion of the upper surface of the indoor unit body 21. Figure 8a Figure 8b As shown, the indoor unit 20 can include an indoor unit body 21, an operation panel 23, an evaporator 22, an indoor unit blower fan 24, and an indoor unit connector 25.

[0052] ​As described below, in the present application, the indoor unit 20 can also be used in a state of being inserted into the outdoor unit 10 or in a state of being separated from the outdoor unit 10. In this operation structure, if the indoor unit 20 is used in a state of being inserted into the outdoor unit 10, the indoor unit connector 25 of the indoor unit 20 needs to be tightly combined with the outdoor unit connector 15 of the outdoor unit 10.

[0053] In a state of the indoor unit 20 being inserted into the outdoor unit 10, if the indoor unit 20 is separated from the outdoor unit 10, an external force needs to be applied to pull the indoor unit 20, as shown in Figure 8a A handle groove 29 is formed at a front surface portion of the indoor unit body 21, by which the indoor unit 20 can be further easily separated from the outdoor unit 10. As described above, in the case where the handle groove 29 is formed at the front surface portion of the indoor unit body 21, the device can be operated by touching the operation panel 23 during the process of separating the indoor unit 20 from the outdoor unit 10 through the handle groove 29. Therefore, it is preferable that the operation panel 23 be formed at a front portion of the upper surface of the indoor unit body 21.

[0054] Also, as shown in Figure 7a and Figure 7b The present application does not exclude a case where an auxiliary outdoor unit connector 150 is provided at the other side surface portion of the outdoor unit body 11. Like the outdoor unit connector 15, in addition to the outdoor unit wire connection portion and the outdoor unit wire connection portion, the auxiliary outdoor unit connector 150 is also provided with an outdoor unit drain pipe connection portion and an outdoor unit wire connection portion. Reference numeral 151, which is not described, is a cover.

[0055] If the auxiliary outdoor unit connector 150 is provided at the other side surface portion of the outdoor unit body 11, even if the indoor unit 20 is separated from the outdoor unit 10, one end portion of the connection pipe 40 can be connected to the auxiliary outdoor unit connector 150 and the other end portion of the connection pipe 40 can be connected to the indoor unit connector 25 to operate the air conditioning device in a similar manner to the example shown in Figure 2b

[0056] Like the embodiment shown in Figure 2b , the indoor unit of the present embodiment can also be used in a state of being separated from the outdoor unit, and since the outdoor unit connector connected to one end portion of the connection pipe is exposed to the outer surface of the outdoor unit, the connection work between the outdoor unit and the connection pipe can be further easily performed.

[0057] ​As described above, when the auxiliary outdoor unit connector is provided on the outer surface of the outdoor unit body, not only the outdoor unit connector 15 provided on the center portion of the partition 32 at the rear of the outdoor unit body 11 can be omitted, but also a structure that operates independently of the outdoor unit connector 15 can be configured. In this case, the former is a structure in which the outdoor unit portion 10 is provided with only one outdoor unit connector, and the latter is a structure in which the outdoor unit portion 10 is provided with two outdoor unit connectors.

[0058] Also, as shown in Figure 1 and Figure 5 , the present application is provided with an opening and closing door 19 at a side portion of the housing body 13, and a pressurizing ring 27 is provided at an outer surface portion of the indoor unit connector 25. In this case, it is preferable that a screw-engaging portion is formed at an inner surface portion of the pressurizing ring 27, so that the pressurizing ring 27 is combined with the outer surface portion of the indoor unit connector 25 in a rotatable manner.

[0059] As described above, in a state in which the opening and closing door 19 is provided at a side portion of the housing body 13, when the opening and closing door 19 is opened, as shown in Figure 2a , the outdoor unit connector 15 is exposed to the outside. In this state, as the indoor unit portion 20 is inserted into the housing space 131 of the housing body 13, the indoor unit connector 25 of the indoor unit portion 20 combined with the pressurizing ring 27 is directed toward the outdoor unit connector 15.

[0060] As the indoor unit connector 25 is directed toward the outdoor unit connector 15, as shown in Figure 3 , if the pressurizing ring 27 is rotated in one direction, the indoor unit connector 25 can be tightly and stably combined with the outdoor unit connector 15. In a state in which the indoor unit portion 20 is combined with the outdoor unit portion 10, if it is necessary to separate the indoor unit portion 20, the pressurizing ring 27 can be rotated in the other direction to easily separate the indoor unit portion 20 from the outdoor unit portion 10.

[0061] The battery 30 is electrically connected to the outdoor unit portion 10 and the indoor unit portion 30, respectively, and is built in at a lower portion of the outdoor unit portion 10. In this case, as shown in Figure 1 , the battery 30 can also be configured to be inserted in a sliding manner from the front or rear lower portion of the outdoor unit body 11. In this case, the inspection work, replacement work, or charging work of the battery can become very simple.

[0062] Hereinafter, the operation structure of the present application will be briefly described based on the embodiment in which the opening and closing door 19 and the pressurizing ring 27 are provided.

[0063] First, the indoor unit portion 20 is configured to operate in a state in which it is inserted into the outdoor unit portion 10. As shown in Figure 3As shown, with the door 19 open or closed, the indoor unit 20 slides toward the housing body 13 of the outdoor unit 10. If it is inserted to a predetermined depth into the housing space 131, the indoor unit connector 25 provided in the indoor unit 20 and the outdoor unit connector 15 provided in the outdoor unit 10 are positioned facing each other.

[0064] That is, the first indoor unit refrigerant connection part 251, the second indoor unit refrigerant connection part 253, the indoor unit drain pipe connection part 255, and the indoor unit wire connection part 257 of the indoor unit connector 22 can be positioned relative to the first outdoor unit refrigerant connection part 151, the second outdoor unit refrigerant connection part 153, the outdoor unit drain pipe connection part 155, and the outdoor unit wire connection part 157 of the outdoor unit connector 15, respectively.

[0065] In this state, as shown in the figure, if the pressure ring 27 is rotated in one direction (refer to the solid line direction), the first indoor unit refrigerant connection 251, the second indoor unit refrigerant connection 253, the indoor unit drain pipe connection 255, and the indoor unit wiring connection 257 of the indoor unit connector 22 will be tightly connected to the first outdoor unit refrigerant connection 151, the second outdoor unit refrigerant connection 153, the outdoor unit drain pipe connection 155, and the outdoor unit wiring connection 157, respectively. If the pressure ring 27 makes the indoor unit connector 22 tightly connected to the outdoor unit connector 15, the open door 19 will be closed, and the device will be operated using the control panel 23 to cool the space.

[0066] Even when it is difficult to place the outdoor unit 10 in additional space, this structure, in which the indoor unit 20 is inserted into the outdoor unit 10 for operation, can be easily used. Furthermore, this structure can also be implemented when the air conditioning unit is not in operation and is stored or used as a portable air conditioning unit such as a car, because the indoor unit 20 is inserted into the outdoor unit 10 and forms an integrated structure.

[0067] Next, the operation of the indoor unit 20 with the outdoor unit 10 detached will be explained. First, as shown in Figure 2, the opening / closing door 19 is opened. Figure 3 As shown, if the opening and closing door 19 is opened, the pressure ring 27 is rotated in the other direction (refer to the direction of the dotted line) to separate the indoor unit connector 25 from the outdoor unit connector 15.

[0068] like Figure 2a As shown, if the indoor unit connector 25 and the outdoor unit connector 15 are separated, the indoor unit section 20 can be slid along the rear to remove it from the housing body 13 of the outdoor unit section 10. Figure 2bAs shown, if the indoor unit part 20 is removed, both end portions of the connection pipe 40 are connected to the indoor unit connector 25 of the indoor unit part 20 and the outdoor unit connector 15 of the outdoor unit 10, respectively. In this case, the connection pipe 40 is provided with a first connection refrigerant pipe, a second connection refrigerant pipe, a connection drain pipe, and a connection electric wire.

[0069] If the indoor unit part 20 is connected to the outdoor unit part 10 through the connection pipe 40, the opened opening and closing door 19 is closed and the device is operated by the operation panel 23, so that the space is refrigerated. This operation structure can be used in the case where the outdoor unit part 10 is positioned at a place separated from the air (positioning space of the indoor unit part 20) to be refrigerated, in which case the refrigerating capacity can be greatly increased as desired. Even in the case where the outdoor unit part 10 and the indoor unit part 20 are positioned in the same space, if the outdoor unit part 10 is positioned at the peripheral portion to the maximum, the refrigerating capacity can be increased compared to the case where the outdoor unit part 10 is positioned in the center of the space. Figure 1 The operation structure shown is improved.

[0070] On the other hand, the present application is as shown in Figure 2a and Figure 4 In the housing body 13 of the outdoor unit part 10, a refrigerant supplement injection end 17 is protrusively formed at a partition 131 side portion behind the housing space 131.

[0071] The refrigerant supplement injection end 17 refers to a portion for supplementing refrigerant from the outside, is preferably separated from the outdoor unit connector 15 by a predetermined interval, and preferably constitutes a structure for communicating with the connection pipe 154 for connecting the condenser 14 and the second outdoor unit refrigerant connection part 153 through a bypass pipe 171. A non-illustrated check valve can be separately provided in the refrigerant supplement injection end 17.

[0072] If the indoor unit part 20 is frequently separated from the outdoor unit part 10 due to long-term use of the present application, it is possible that a predetermined amount of refrigerant is leaked to the outside during this process, thereby reducing the refrigeration efficiency. In this case, as shown in Figure 9 in a state where the opening and closing door 19 is opened, after connecting the refrigerant supplement pipe 53 to the refrigerant supplement injection end 17, if the refrigerant stored in the refrigerant tank 51 is supplemented, stable refrigeration can be achieved.

[0073] In addition, as shown in Figure 5 the present application does not exclude the case where a condensate water storage platform 26 is provided at the inner lower side of the indoor unit body 21 and the condensate water storage platform 26 and the indoor unit drain pipe connection part 255 are connected to each other through a connection hose 28. In this case, the evaporator 22 and the indoor unit supply fan 24 are preferably provided at the upper surface portion of the condensate water storage platform 26, respectively.

[0074] As shown in Figure 4As shown, preferably, when the indoor unit body 21 is provided with a condensate water storage platform 26, the drain hose 18 is provided in the outdoor unit part 10. One end of the drain hose 18 is connected to the outdoor unit drain pipe connection part 155, and the other end extends through from the rear surface of the outdoor unit body 11.

[0075] After compression and condensation in the outdoor unit 10, if the refrigerant is supplied to the indoor unit 20 and evaporated by the evaporator 22, a large amount of condensate is generated in this process. The condensate storage platform 26 serves as a temporary storage area for the condensate generated during the refrigeration process. The condensate temporarily stored in the condensate storage platform 26 is discharged to the outside of the unit through the connecting hose 28, the indoor unit drain pipe connection 255, the outdoor unit drain pipe connection 155, and the drain hose 18.

[0076] As described above, if a condensate reservoir 26 is installed in the indoor unit 20 and the generated condensate is discharged sequentially to the outside of the device, the phenomenon of generated condensate flowing into the cooling space through the indoor unit 20 can be fundamentally prevented even if the device is running for a long time. In this case, if an additional pump or motor is installed in the outdoor unit 10, the condensate can be further and easily discharged through the drain hose 18.

[0077] And, as Figure 10 As shown, the present invention provides a support plate 215 on the lower surface of the indoor unit body 21. As shown in the figure, preferably, when the support plate 215 is folded, it is provided on the lower surface of the indoor unit body 21. Preferably, the vertical width (height) of the front part of the support plate 215 is greater than the vertical width (height) of the rear part.

[0078] Because fluids such as air undergo convection, rising with increasing temperature and falling with decreasing temperature, supplying cooling air upwards is beneficial for effectively cooling a specific space. Therefore, this invention utilizes the support plate 215 to discharge cooling air at a predetermined angle to the front surface of the indoor unit 20, thereby improving the cooling efficiency of the space.

[0079] While the above description defines the preferred embodiments of the present invention, it is obvious that this is merely an example, and the present invention is not limited thereto. It can be implemented in various ways, and additional technical features can be added based on the disclosed technical ideas.

[0080] Industrial availability

[0081] The present application is a small air conditioner, so it is convenient to store and can be carried by the user. It can also be installed in a small car and used in the state of being connected to or separated from the outdoor unit.
