[Technical field]

[0001] The present invention relates to an all-in-one air conditioner and a soundproof room, and more particularly to a portable soundproof room that can be installed and used indoors or outdoors, and an all-in-one air conditioner used therein. [Background technology]

[0002] Soundproof rooms that have soundproofing properties to keep the room quiet have been installed in various places such as homes and companies and used for various purposes. In recent years, in response to the growing interest in teleworking in various companies, portable soundproof rooms for teleworkers have been developed and put into operation. In these soundproof rooms, an integrated air conditioner with a refrigeration cycle for cooling is installed in a cabinet, and a comfortable air environment for users can be easily realized (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2022-61598 A Summary of the Invention [Problem to be solved by the invention]

[0004] The soundproof room described in Patent Document 1 has an integrated air conditioner installed under the table and blows out cold or warm air from a front air outlet, and the temperature setting of the indoor space is achieved by interaction with a ventilation fan installed on the ceiling. However, because the cold air blown out from the air outlet is heavier than the air in the room and the warm air is lighter than the air in the room, it takes time for the cold or warm air to be conveyed to the user as a change in the thermal environment (a feeling of coolness, warmth, airflow, etc.), and there is a problem that the warm air does not reach the area around the feet of the seat sufficiently, especially during heating operation in winter.

[0005] SUMMARY OF THE PRESENT EMBODIMENTS The present invention aims to provide an integrated air conditioner that can directly notify users of changes in the thermal environment in an office space within a short period of time, and a soundproof room equipped with the same. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the integrated air conditioner of the present invention is an integrated air conditioner that houses a refrigeration cycle for cooling and a heater for heating within a cabinet, and is characterized in that the front of the cabinet is provided with an upper air outlet and a front air outlet whose opening directions are perpendicular to each other, the upper air outlet is provided with an upper air outlet that is rotatably connected around a rotation axis extending in a vertical direction and opens at an angle to the rotation axis extending in the vertical direction, and the front air outlet is provided with a front air outlet that is rotatably connected around a rotation axis extending in a horizontal direction and opens at an angle to the rotation axis extending in the horizontal direction.

[0007] The cabinet has a front air intake on the front side, a rear air intake on the rear side, and an exhaust port on one side, and within the cabinet, a first partition plate that divides the cabinet in the front-to-back direction is provided, thereby defining a rear heat exchange chamber on the rear side, and a second partition plate that further divides the cabinet in the up-down direction is provided on the front side, thereby defining an air blower chamber on the upper side and a front heat exchange chamber on the lower side, and the rear heat exchange chamber has a compressor that drives the refrigeration cycle arranged therein, a condenser arranged corresponding to the position of the rear air intake and a condenser fan arranged corresponding to the position of the exhaust port, the front heat exchange chamber has an evaporator arranged corresponding to the position of the front air intake and an evaporator fan arranged corresponding to the position of the ventilation port of the second partition, and the ventilation chamber has the heater arranged corresponding to the position of the ventilation port.

[0008] Furthermore, a drain water treatment unit is provided at the bottom of the cabinet, and the drain water treatment unit includes a tank for collecting water droplets generated in the evaporator, and an atomization device for atomizing the drain water stored in the tank, and the drain water atomized by the atomization device is guided to the rear heat exchange chamber.

[0009] In addition, the soundproof room of the present invention is a portable soundproof room in which the integrated air conditioner is installed, the soundproof room comprising a housing that forms an office space into which a user can enter and a door connected to the housing, the office space being divided into a table-side space and a seat-side space with a table and a seat paired with the table as the boundary, the integrated air conditioner being arranged such that one side of the cabinet is aligned with the inner wall surface of the housing and across both the table-side space and the seat-side space, and the top-side outlet pipe and front-side outlet pipe are provided in the seat-side space. Effect of the Invention

[0010] According to the soundproof room of the present invention, an integrated air conditioner is installed on the floor on one side of an office space, and is arranged across a table side space and a seat side space that are formed by dividing the office space at the table end position, and an upper surface air outlet and a front surface air outlet whose opening directions are perpendicular to each other are provided at the front of the cabinet located in the seat side space on one side, and an upper surface air outlet is connected to the upper surface air outlet and rotatable around a vertical axis of rotation, opening at an angle to the axis of rotation, and a front surface air outlet is connected to the front surface air outlet and rotatable around a horizontal axis of rotation, opening at an angle to the axis of rotation. Therefore, it is possible to provide the upper surface air outlet and the front surface air outlet within reach of a user seated at the table, and each air outlet can be rotated as desired by operating the air outlet at hand while seated, allowing the air to reach the user's face or feet. In other words, the refreshing feeling of cool air and the warmth of warm air in the office space are directly transmitted to the user in a short time, and particularly during heating operation in winter, warm air can be sufficiently distributed around the feet of the seat.

[0011] In addition, a partition plate is provided inside the cabinet to separate two heat exchange chambers and one ventilation chamber, where various parts required for cooling and heating operations are functionally arranged, so that the refrigeration cycle (compressor) and heater can be selectively operated while sharing the ventilation function of the ventilation chamber. Furthermore, a drain water treatment unit that operates during cooling operation is provided, so that the drain water (mist) atomized by the atomization device can be carried by warm air and sent outside, resulting in a highly practical all-in-one air conditioner configuration that does not require draining work, thereby contributing to the proper operation of soundproof rooms.

[0013] 1 to 18 show an embodiment of the present invention. As shown in Fig. 1 to 6, the soundproof room 11 is formed by a housing 12 and a door 13, has a work space where a user can enter and work, and is installed in places where various people pass through, such as inside a station, an airport, a commercial facility, an exhibition hall, an outdoor plaza, inside a store, a hotel, an apartment building, or an office. The soundproof room 11 can also transmit and receive data to and from an external device via a network such as the Internet. A user who uses the soundproof room 11 can use a video conference terminal installed in the soundproof room 11 to hold a video conference with a user who uses an external device having a video conference function.

[0014] The housing 12 is made of materials such as metal, wood, or resin, and is formed as a rectangular parallelepiped with a large overall height, with an opening for users to enter and exit on one side, the front side (FIG. 1). Casters 14 are provided on the four corners of the bottom surface of the housing 12, and adjusters 15 are provided in the vicinity of the casters 14. After using the casters 14 to move the soundproof room 11 to the installation location, the installer of the soundproof room 11 can fix the soundproof room 11 in a fixed position by adjusting the length of the adjusters 15 so that it is equal to the distance between the bottom surface of the soundproof room 11 and the floor surface.

[0015] The door 13 is connected to the housing 12 so as to be able to close the opening of the housing 12, and is configured as an outward-opening door that can be opened and closed around the joint with the housing 12 by operating a handle 13a. The door 13 is provided with a door glass 13b, which makes it possible to view the inside of the soundproof room 11 from the outside.

[0016] The inside of the housing 12 is provided with a sound-absorbing material, so that the voice of the user inside the soundproof room 11 and the voice of the user using the external device are unlikely to leak out of the soundproof room 11. Therefore, even if the soundproof room 11 is installed in a public place where an unspecified number of people pass by, the user can safely talk about highly confidential information. In addition, the specifications of the flooring are a double-floor structure in which a space under the floor is formed between the upper and lower floorboards by interposing multiple beams inside the framed base material, and the strength required for people to enter and exit and to support the seats 16, etc. is ensured. Furthermore, from the viewpoint of disaster prevention, non-flammable materials are used for the sound-absorbing materials on the inner walls and the tiles laid on the floor.

[0017] The seat 16 is formed with a width sufficient for one adult to sit comfortably, and the backrest 16a is positioned adjacent to one of the inner wall surfaces 12a which face each other in the width direction of the housing 12 (the left-right direction in FIG. 6), and a table 17 which can be used while seated is attached in a cantilever fashion to the other inner wall surface 12b.

[0018] The table 17 extends in the depth direction of the housing 12 (the up and down direction in Figure 6), and in the range where it overlaps with a projection line 18 obtained by rotating and projecting the door 13 toward the inside of the room, the table end (edge) 19 is cut in a straight or curved shape, thereby forming a door separation portion 20 that is separated from the door 13 in the depth direction.

[0019] The office space has the dimensions of height, width, and depth set to form a rectangular parallelepiped that does not impede the entrance and exit of users and does not impair the convenience of users working in the office when a set of seats 16 and tables 17 are arranged. As shown in Fig. 6, the office space is divided into a table side space 21 where the table 17 is arranged and a seat side space 22 where the seat 16 is arranged, with the position of the table end 19 as the boundary. Both spaces 21, 22 are basically obtained by dividing the office space into roughly equal halves in the width direction.

[0020] A lock (not shown) is provided between the housing 12 and the door 13, and is switched between an unlocked state in which the door 13 can be opened and a locked state in which the door 13 cannot be opened under the control of a control unit (CPU) built into the housing 12. The lock is controlled to unlock or lock the soundproof room 11 by switching between the unlocked state and the locked state by a user's operation from inside the housing 12 or by switching by remote control.

[0021] In addition, an operation reception unit 23 that receives user operations is provided on the front side of the housing 12. The operation reception unit 23 is, for example, a display with a touch panel, and receives one of 30 minutes, 60 minutes, and 90 minutes as the planned use time input by the user. Furthermore, a reservation can be made by specifying the date and time in advance from an information terminal such as a smartphone. When the reserved time arrives, the user touches the operation reception unit 23 of the soundproof room 11 that he or she has reserved, and reads the QR code (registered trademark) displayed on the screen with the information terminal. Then, when the necessary authentication based on the user identification information is completed in a management device (server) on the network, the soundproof room 11 is unlocked and the room becomes available for entry. The fee to be paid is determined according to the planned use time, and power is supplied to the electronic devices provided inside the soundproof room 11 from the completion of the payment until the planned use time has elapsed.

[0022] The electronic devices function by receiving power from a power supply unit built into the housing 12, and include permanently installed video conference equipment 24, lighting 25, security cameras 26, speakers 27, and air conditioning equipment installed on the ceiling 12c of the housing 12, as well as computers or mobile terminals brought in by users. The air conditioning equipment ventilates the interior space of the soundproof room and adjusts the internal temperature, and examples of such equipment include an integrated air conditioner 28 for heating and cooling installed on the floor 12d, and a ventilation fan 29 installed on the ceiling 12c. The specific configuration of the integrated air conditioner 28 will be described later.

[0023] When the control unit receives an instruction from a management device that has completed user authentication while the power supply unit is connected to an external power outlet, the control unit controls the power supply unit to start supplying power to various electronic devices such as air conditioning equipment. In other words, these devices operate under the control of the control unit from the completion of payment until the scheduled time of use has elapsed. In addition, the user can If necessary, power can be supplied using a connection port 30 for electronic devices installed in the room (FIG. 4).

[0024] An automatic fire extinguisher 31 is provided on the ceiling 12c of the soundproof room 11 as one of the disaster prevention facilities. The automatic fire extinguisher 31 is a downward discharge type fire extinguisher (sprinkler) that does not require a power source, and is integrally provided with an extinguishant container 32 filled with an extinguishant, and a discharge nozzle 33 that is provided at the center of the lower end of the extinguishant container 32 and can discharge the extinguishant into the room when detected by a built-in heat detector. A low melting point metal is used for the heat detector, and in the event of an emergency when a fire occurs, when a heat collecting plate at the lower end of the discharge nozzle 33 detects heat from the fire source, the low melting point metal melts and the pressurized gas in the container blows off the sealing plug and the heat collecting plate, and the discharge of the extinguishant begins.

[0025] The automatic fire extinguishing device 31 is installed in a position that takes into consideration the placement of the lighting 25, speaker 27, ventilation fan 29, various cover members 34, etc., so as not to impair the functionality of the soundproof room 11 (Fig. 3). In particular, the position of the discharge nozzle 33, i.e., the position of the heat detector and the position of the ventilation fan 29, are arranged side-by-side so that the rising air current formed by the operation of the ventilation fan 29 will promote the rise of heat from the fire source.

[0026] Meanwhile, in the soundproof room 11, air conditioning that can provide a comfortable air environment without causing thermal discomfort to users working in the room under normal use conditions is desired. In particular, when considering that the soundproof room 11 is installed in a public facility such as a train station, the temperature in the room will be higher than the outside air temperature in summer, while in winter, the heat will quickly rise to the ceiling 12c, causing the floor near the floor 12d to be cold. For this reason, an integrated air conditioner 28 that prepares the room for cooling or heating is installed on the floor of the soundproof room 11.

[0027] 7 to 18 show an all-in-one air conditioner 28 applied to the soundproof room 11 of the present invention. The all-in-one air conditioner 28 houses a refrigeration cycle for cooling and a PTC (Positive Temperature Coefficient) heater, which is a heating element, in the same cabinet, and by operating the attached operation panel, it is possible to select the operation mode (cooling or heating) and input the set temperature.

[0028] The cabinet 35 has a sheet metal structure excellent from the viewpoint of disaster prevention, and as shown in Fig. 7 to Fig. 15, when viewed from the seat side space 22 facing the front surface 35a (Fig. 8), it is formed in a rectangular box shape with a narrow width from left to right, and the right side surface 35b is aligned with the door side and the opposite housing inner wall surface 12e, and is arranged across both the table side space 21 and the seat side space 22 (front-rear space). As a result, the integrated air conditioner 28 is supported horizontally by four support legs 36 provided at the bottom of the cabinet 35 as shown in Fig. 4 to Fig. 6, and about 2 / 3 of the front-rear direction length of the cabinet 35 is placed in a state where it is appropriately accommodated under the table 17. In this way, the cabinet 35 arranged under the table 17 at the back of the work space leaves a space on the left side surface 35c side, ensuring a wide foot space for the seat 16.

[0029] The front part of the cabinet 35 located in the seat side space 22, that is, the front upper corner part mainly formed by the top surface 35d and the front surface 35a, is provided with an upper surface air outlet 37 and a front surface air outlet 38, which are circular openings and have opening directions perpendicular to each other, as shown in Fig. 14. Here, as shown in Fig. 15, the upper surface air outlet 37 is provided with an upper surface side outlet pipe (e.g., a 45-degree elbow pipe) 40 that is rotatably connected to a rotation shaft 39 extending in the vertical direction and opens in an oblique direction (in the direction of arrow A) relative to the rotation shaft 39 extending in the vertical direction. Meanwhile, the front surface air outlet 38 is provided with a front surface side outlet pipe (e.g., a 45-degree elbow pipe) 42 that is rotatably connected to a rotation shaft 41 extending in the horizontal direction and opens in an oblique direction (in the direction of arrow B) relative to the rotation shaft 41 extending in the horizontal direction.

[0030] The upper surface side blowing pipe 40 and the front surface side blowing pipe 42 are made of common parts, and have an intersection P where their rotation axes 39, 41 intersect at a right angle (FIG. 15). The specific configuration of each blowing pipe 40, 42 is centered on a cylinder 43 formed with a bending angle of, for example, 45 degrees, and is provided at both end openings of the cylinder 43 with annular plate-shaped flanges 44 assembled concentrically with the air outlets 37, 38, and a disk-shaped lid 45 with multiple slit holes for releasing the airflow guided by the cylinder 43.

[0031] The flange 44 engages with an annular groove (not shown) formed by multiple rubber plates, and is elastically pressed from the outside by a metal plate 46. In this attached state, the blow-out pipes 40, 42 are disposed within reach of a user seated facing the table 17, in other words, within reach by simply bending and straightening the arms, and when rotated manually, the flange 44 slides and rotates relative to the rubber plate, changing the oblique opening direction, i.e., the direction in which the airflow is discharged from the air outlets 37, 38.

[0032] The cover 45 is formed slightly larger than the outer diameter of the cylinder 43, and has a shape that is convenient for hanging the fingers, that is, a shape that prevents slipping and improves the ease of holding (grip) when rotating the blow-off pipes 40, 42. In addition, since continuous slit holes are provided, there is no need to worry about objects falling from the table surface getting into the inside of the blow-off pipes 40, 42, and the design is excellent.

[0033] Here, a front air intake port 47 for taking in indoor air is provided on the front surface 35a of the cabinet 35 (FIG. 8). A rear air intake port 48 for taking in indoor air is also provided on the rear surface 35e of the cabinet 35 (FIG. 11). As shown in FIG. 9, the right side surface 35b of the cabinet 35 is provided with an exhaust port 49 at a position corresponding to the table side space 21. A cylindrical exhaust duct (e.g., a straight pipe) 50 is airtightly connected to the exhaust port 49, ensuring ventilation of the hot air from the exhaust port 49. Furthermore, as shown in FIGS. 4 and 6, the tip of the exhaust duct 50 is inserted into a discharge portion formed by fitting a duct cover 51 into a wall hole of the housing 12.

[0034] 13 and 14, a first partition plate 52 is provided inside the cabinet 35 to define a rear heat exchange chamber 53 on one rear side in the front-to-rear direction (the left side in FIG. 13), and a second partition plate 54 is provided on the other front side to define an air blower chamber 55 on the upper side in the up-down direction and a front heat exchange chamber 56 on the lower side. Also, a drain water treatment unit 57 that operates during cooling operation is provided at the bottom of the cabinet 35.

[0035] As main components, a compressor 58 is disposed in the rear heat exchange chamber 53, and a condenser 59 and a condenser fan 60 are disposed in correspondence with the position of the rear intake port 48 and the position of the exhaust port 49, respectively, in a direction that takes proper ventilation into consideration. Meanwhile, an evaporator 61 and an evaporator fan 62 are disposed in correspondence with the position of the front intake port 47 and the position of the ventilation port 54a of the second partition plate 54, respectively, in the front heat exchange chamber 56, respectively, in a direction that takes proper ventilation into consideration (FIG. 14).

[0036] Here, the first partition plate 52 and the second partition plate 54 are assembled in the cabinet 35 with a plate bent part having a bending angle of about 45 degrees from the plate surface, and the air outlet of the evaporator fan 62 is located in a space 63 that is triangular in side view and provided between the plate surfaces. As a result, the evaporator fan 62 is set in an installed state so that the air blowing direction is diagonally upward so as to target a corner part 64 of the blower chamber 55.

[0037] The air blowing chamber 55 forms an internal space in the front upper corner of the cabinet 35, and a PTC heater 65 is disposed in correspondence with the position of the ventilation opening 54a of the second partition plate 54. In addition, two rectifying plates 66 are provided to guide the air blown from the evaporator fan 62, more specifically, the air blown through the PTC heater 65, to the upper surface side blowing pipe 40 and the front surface side blowing pipe 42 (FIG. 13). The air blown passes through a rectangular cross-sectional ventilation path formed by the plates on the left and right side surfaces 35b, 35c of the cabinet 35 and the upper and lower rectifying plates 66, and is sent out to the air blowing openings 37, 38 on the upper surface and the front surface.

[0038] Although not shown, the drain water treatment unit 57 includes a tank that collects water droplets generated in the evaporator 61, and an atomization device that atomizes the drain water stored in the tank. For example, when the water level in the tank reaches a set value, an energized transducer generates ultrasonic waves to atomize the drain water. This atomized drain water (mist) rises and is guided to the rear heat exchange chamber 53. By providing multiple transducers, it is possible to atomize the drain water even if one transducer breaks down.

[0039] [Cooling operation] When the integrated air conditioner 28 thus constructed is used, during cooling operation, the circuit of the PTC heater 65 is in an off state, and the refrigeration cycle is operated by driving the compressor 58. As a result, the refrigerant is made into a high-pressure state by the compressor 58 and sent to the condenser 59, where it is condensed and dissipates heat. Furthermore, the low-temperature refrigerant that has passed through the expansion valve is sent to the evaporator 61, where it absorbs heat (cooling effect), becomes in a low-pressure state, and is returned to the compressor 58.

[0040] Here, the air (room air) taken in from the rear air intake 48 by the operation of the condenser fan 60 is heated in the condenser 59, becomes warm air and is blown out from the condenser fan 60, passes through the exhaust port 49 and the exhaust duct 50, and is sent out to the external space (outdoors) of the housing 12.

[0041] The air (room air) taken in from the front air intake 47 by the operation of the evaporator fan 62 is cooled by the evaporator 61, becomes cold air, and is blown out from the evaporator fan 62. In the air blowing chamber 55, the air is divided into an upward air flow and a forward air flow. The upward air flow passes through the upper air outlet 37 and is guided to the upper air outlet pipe 40, and is deflected diagonally by the bending action of the upper air outlet pipe 40 before being sent out to the office space (room). On the other hand, the forward air flow passes through the front air outlet 38 and is guided to the front air outlet pipe 42, and is deflected diagonally by the bending action of the front air outlet pipe 42 before being sent out to the office space (room). In this way, the integrated air conditioner 28 performs cooling operation.

[0042] When the air taken in from the front air intake 47 is cooled by the evaporator 61, water droplets are generated in the evaporator 61. The water droplets that accumulate in a tray (not shown) in the evaporator 61 flow from a drain outlet (not shown) into the tank of the drain water treatment unit 57. When the water level in the tank reaches a set value, the drain water is atomized to generate mist. The generated mist rises from an opening in the bottom of the rear heat exchange chamber 53 and is sent outside together with the warm air sent to the external space (outdoors) described above. This eliminates the need to drain the drain water during cooling operation.

[0043] [Heating operation] During heating operation, the refrigeration cycle is stopped and the circuit of the PTC heater 65 is turned on. As a result, the air taken in from the front air intake 47 is heated by the operation of the evaporator fan 62, which is also used in heating operation, and after flowing into the blower chamber 55 as warm air, it is sent out to the office space (room) through the upper and front outlet pipes 40, 42. In this way, the heating operation of the integrated air conditioner 28 is performed. The PTC heater 65 is a heater that utilizes the PTC characteristic that the resistance value increases as the temperature increases, so once a certain temperature is reached, the temperature does not increase any further, preventing overheating and ensuring energy saving and safety.

[0044] During heating operation, the operation of the refrigeration cycle is stopped, and therefore no drain water is generated because there is no condensation by the evaporator 61. Therefore, during heating operation, the drain water treatment unit 57 does not operate.

[0045] In the soundproof room 11 thus formed, after starting the integrated air conditioner 28 by operating the operation panel, the air outlet pipes 40, 42 can be rotated as desired by hand while seated, and cool or hot air can be concentrated around the user's face or feet. For example, as shown in Figs. 16 and 17, at the start of use, the upper air outlet pipe 40 is positioned in front of the table edge 19 and blows air in a diagonal upward direction along a vertical plane including the table edge 19. As a result, as can be imagined from Figs. 4 to 6, the air blown directly hits the user's face, which promotes the evaporation of sweat and provides a high feeling of coolness, especially during cooling operation in summer.

[0046] Looking at the orientation of the front air outlet pipe 42, in the state shown in Figures 16 and 17, air is blown out horizontally toward the seat 16. When the front air outlet pipe 42 is rotated counterclockwise in this state, as shown in Figure 18, by setting the rotation angle θ from the horizontal to, for example, 60 degrees, air is blown out obliquely downward so as to get under the seat 16. This makes it easier for the air to reach the vicinity of the floor, and the feeling of warmth at the feet (calf area) can be sustained, particularly in heating operation in winter.

[0047] In this way, according to the soundproof room 11 of the present invention, the integrated air conditioner 28 installed on the floor on one side of the office space is arranged across the table side space 21 and the seat side space 22 which are formed by dividing the office space at the table end 19 position, and an upper surface air outlet 37 and a front surface air outlet 38 whose opening directions are perpendicular to each other are provided at the front of the cabinet 35 located in the seat side space 22 on one side, and an upper surface side outlet pipe 40 which is connected to the upper surface outlet 37 and can rotate around a vertical rotation axis 39 opens at an angle to the rotation axis 39, and a front surface side outlet pipe 42 which is connected to the front surface outlet 38 and can rotate around a horizontal rotation axis 41 opens at an angle to the rotation axis 41, so that the upper surface side outlet pipe 40 and the front surface side outlet pipe 42 can be provided within reach of a user seated facing the table 17, and each outlet pipe 40, 42 can be rotated as desired by operating it by hand while in a seated position to deliver air to the face or around the feet. That is, the refreshing feeling of cool air and the warm feeling of warm air in the office space are directly transmitted to the user in a short time, and particularly during heating operation in winter, warm air can be sufficiently distributed around the feet of the seat 16.

[0048] Also, by providing partitions 52, 54 within cabinet 35 to define two heat exchange chambers 53, 56 and one ventilation chamber 55, and functionally arranging various parts necessary for cooling and heating operations there, it is possible to share the ventilation function of ventilation chamber 55 while selectively operating refrigeration cycle (compressor 58) and heater 65. Furthermore, by providing drain water treatment unit 57 that operates during cooling operation, it becomes possible to send drain water (mist) atomized by the atomization device to the outside of the room on hot air, and a highly practical all-in-one air conditioner 28 configuration that does not require draining work is obtained, thereby contributing to the proper operation of soundproof room 11.

[0049] The present invention is not limited to the above-mentioned embodiment, and the soundproof room can be equipped with various necessary equipment in addition to air conditioning and disaster prevention equipment. The shape of the housing is not limited to a rectangular parallelepiped, but may be a cylindrical shape, and can be formed with a space that can accommodate not only one person but also two or more people, as long as the advantages of a mobile, portable soundproof room are not lost. In this case, the configuration and arrangement of the equipment and air conditioning equipment can be changed as long as the user does not feel thermal discomfort and the office space can be used comfortably.

[0050] Furthermore, various specifications of the all-in-one air conditioner can be adopted as long as it has two blow-out pipes arranged at right angles to the front upper corner of the cabinet, and the sheet metal structure of the cabinet (including the shape and arrangement of the partition plate, the straightening plate, etc.) and the arrangement of the devices housed in the cabinet can also be changed as appropriate. In addition, the shape and size (outer diameter, bending angle, etc.) of the blow-out pipes are optional, and for example, they may be formed using flexible pipes such as flexible ducts. In addition, the orientation of each blow-out pipe on the upper and front sides is not particularly limited in use, and they can be rotated as necessary to adjust the blow-out direction of the air to the optimal direction for the user.
