Description

[Technical Field]

[0001] The present invention relates to a spot air conditioning booth consisting of a main housing and a sub-housing, and more specifically, to a spot air conditioning booth in which the main housing and the sub-housing are connected via an air supply duct and a circulation duct, and temperature-controlled air from a spot air conditioner installed in the sub-housing is guided into the main housing via the air supply duct, and part of the air in the main housing is returned to the sub-housing via the circulation duct to exchange heat with the air in the sub-housing, thereby making it possible to suppress fluctuations in the temperature in the sub-housing due to use of the spot air conditioner. [Background technology]

[0002] The present applicant has developed and provided an air conditioning booth that allows components to be easily assembled and disassembled, significantly improving loading capacity and transportation costs, etc. (Patent Publication No. 7030346 (Patent Document 1)).

[0003] After filing the above application, the applicant has developed and provided a spot air conditioning booth that has a sub-casing on the side of the main casing that can house a portable spot air conditioner, allowing the air flow from the spot air conditioner to be efficiently guided into the main casing (Patent Application No. 2023-61840 (Patent Document 2)).

[0004] These spot air conditioning booths can be placed outdoors or inside factory buildings, allowing people to avoid the extreme heat or cold outdoors or indoors.Since the casing is compact and portable, they are also increasingly being used as simple rest areas. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 7030346 [Patent Document 2] Patent Application No. 2023-61840 Summary of the Invention [Problem to be solved by the invention]

[0006] In the spot air conditioning booth developed by the present applicant, as described in Patent Document 2, the spot air conditioner is housed in a dedicated sub-casing, which makes it possible to efficiently send the temperature-controlled air flow from the spot air conditioner into the inside of the main casing, while also improving the freedom of placement of the spot air conditioner relative to the main casing, protecting the spot air conditioner from external environments such as direct sunlight, and enabling it to be operated efficiently.

[0007] However, by housing the spot air conditioner in a sub-housing in this way, there is a possibility that a problem will arise in terms of heat or cold dissipation within the sub-housing due to the heat exchange action in the spot air conditioner main body.

[0008] In other words, when a spot air conditioner is used for cooling, for example, hot air will be blown out of the exhaust port of the spot air conditioner main body in addition to the temperature-controlled air, and the temperature of the main body will also rise, which may cause the temperature inside the sub-housing to rise.

[0009] Therefore, when the temperature inside the sub-housing rises in this way, the efficiency of sending cool air to the main housing decreases, and there is a problem that the cool air capacity decreases drastically, especially when the temperature inside the sub-housing exceeds 50°C.

[0010] Therefore, the present invention aims to solve the above-mentioned problems and relates to a spot air conditioning booth in which a sub-casing capable of storing a portable spot air conditioner is placed on the side of a main cabinet, and which can efficiently blow airflow such as cold air from the spot air conditioner into the main cabinet, and its object is to suppress temperature changes of the spot air conditioner in the sub-casing and efficiently guide the airflow of cold or warm air from the spot air conditioner into the main cabinet. [Means for solving the problem]

[0011] In order to solve the above problems, the present invention provides a spot air conditioning booth comprising a main housing and a sub-housing, the main housing and the sub-housing being connected by a cylindrical air supply duct and a circulation duct made of a flexible material, the air supply duct functions as a passage for supplying temperature-controlled air from the spot air conditioner housed in the sub-housing to the main housing side, the circulation duct functions as a passage for supplying air from the main housing to the sub-housing, the main housing and the sub-housing being made of a frame for maintaining the shape of the main housing and the sub-housing in a rectangular column shape, and a film material covering the frame, and one side of the main housing has an entrance / exit section and a semi-transparent or transparent film. a window made of a transparent material is formed, at least one of the other side surfaces is formed with at least one main housing-side intake duct opening and one main housing-side exhaust duct opening, a shape-retaining band is formed at the bottom end of the main housing, a carry-in / out section is formed on one side surface of the sub-housing, and an air supply duct opening, an sub-housing-side intake duct opening, and a sub-housing-side exhaust duct opening are formed on the other side surface, the air supply duct is provided between the air supply duct opening of the sub-housing and the main housing-side intake duct opening, and the circulation duct is provided between the main housing-side exhaust duct opening and the sub-housing-side intake duct opening.

[0012] The above problem is solved by sewing one end of the air supply duct to the main housing side intake duct port and sewing one end of the circulation duct to the main housing side exhaust duct port, or by providing duct port fasteners at the main housing side intake duct port and the main housing side exhaust duct port, and the sub-housing side air supply duct port and the sub-housing side intake duct port, and by providing a cover portion to close unused duct ports, and by providing duct side fasteners at at least one end side of the air supply duct and the exhaust duct that engage with the duct port fasteners, or by A roof unit can be connected to the sub-housing, and the roof unit has a roof unit engagement portion that engages with the engagement portion at the upper end of the frame, and a support cable can be connected to the roof unit. Alternatively, the door stop and opening / closing portion of the door section of the entrance / exit section are each provided with a plurality of hook-and-loop fastener portions that engage with each other, and the hook-and-loop fastener portions are provided with at least four sets of hook-and-loop fasteners, two arranged above and two below, and one or more of the four sets of hook-and-loop fasteners can be selected and engaged to adjust the engagement strength or to deal with deterioration over time, thereby achieving even more effective results. [Effects of the Invention]

[0013] According to the present invention having the above-described configuration, by returning a portion of the temperature-controlled air in the main housing to the sub-housing, it is possible to suppress temperature changes caused by the temperature of the spot air conditioner in the sub-housing rising or falling, thereby preventing a decrease in the operating efficiency of the spot air conditioner and efficiently directing the air flow of cool or warm air from the spot air conditioner into the main housing.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The spot air conditioning booth according to the present invention will be described in more detail below with reference to the drawings. In the following description, the same symbols may be used for the same components even if they may take different forms, and some of the explanations and symbols for overlapping components may be omitted. Furthermore, the size and relative proportions of the components shown in the drawings may be enlarged or exaggerated from their actual size for the sake of convenience, and some parts of the drawings may be omitted for clarity.

[0016] 1 or 2, the spot air conditioning booth according to the present invention is basically composed of a main housing 100 and a sub-housing 300 arranged adjacent thereto, and the main housing 100 and the sub-housing 300 are configured to be able to communicate with each other on their side surfaces via an air supply duct 500 and a circulation duct 700, and the sub-housing 300 can accommodate a spot air conditioner 900, which will be described later. These components will be described in order below.

[0017] First, among the components of the present invention, the main housing 100, as illustrated in FIG. 1 and other figures, is a compartment that separates an area to be temperature-controlled from the external environment. In the example of the main housing 100 illustrated in FIG. 1 and other figures, the main housing 100 has, for example, a rectangular prism shape overall and is basically composed of a frame that supports each side of the rectangular prism shape from the inside to stabilize the shape, and a film material that forms each surface of the rectangular prism shape. However, in the present invention, no film material is used in the portion corresponding to the floor. The main housing 100 can be placed directly in the installation location, or a separate floor board can be placed on top of the main housing 100. Furthermore, although the main housing 100 in the above example is rectangular prism-shaped, it may also be cylindrical or have other shapes as long as it can accommodate entrances and exits, intake ducts, and the like, as described below.

[0018] There are no particular limitations on the frame, so long as it functions as a framework that can maintain the shape of main housing 100. For example, a combination of a pipe or a pipe-like, extendable frame and engaging members that connect multiple such frames may be used, or a framework or connecting members such as those described in Patent Documents 1 and 2 may be used.

[0019] Furthermore, the membrane material that constitutes main housing 100 is not particularly limited as long as it can constitute the outer surface of main housing 100, and it is possible to use canvas, which is commonly used as tent fabric, or a sheet made of synthetic resin with heat-insulating properties, etc. Such membrane material may be made by combining and connecting multiple parts with zippers, hook-and-loop fasteners, or the like, to form such a rectangular prism-shaped space (excluding the floor), or it may be a material that is formed in advance as an outer wall of main housing 100 and is then fitted over the outside of a pre-assembled frame.

[0020] Next, an entrance / exit section 110 for entering and exiting the main housing 100 is formed in the front portion of the main housing 100, and the entrance / exit section 110 further has a semi-transparent or transparent window section 130 formed therein.

[0021] Of these, the entrance / exit section 110 is the part that corresponds to a door for entering and exiting the main housing 100, and a door section 111 is formed near the side that constitutes the entrance / exit section 110, and the door section 111 is formed with an opening / closing section 111K and a door stop section 111T.

[0022] The side surfaces of the opening / closing section 111K and the side surfaces of the door stop section 111T are designed to overlap with each other when viewed from the front, and in the overlapping portion, one or more door engagement sections 111J are provided on the opening / closing section 111K side of the door stop section 111T and the opening / closing section 111K side of the door stop section 111T, which are made of hook-and-loop fasteners BT that engage with each other, or a magnetic sheet and a magnet sheet, etc.

[0023] Therefore, when entering or exiting the main housing 100 through such an entrance / exit section 110, for example, by pulling the handles 110H provided on the inside and outside of the opening / closing section 111K, the engagement of the hook-and-loop fasteners and the like that make up the door engagement section 111J is released, and the opening / closing section 111K of the door section 111 is opened or closed, thereby making it possible to enter or exit the main housing 100 through such an entrance / exit section 110.

[0024] The configuration of the entrance / exit section 100 is not limited to the above configuration as long as it can reduce the leakage of temperature-controlled air inside and allow people to enter and exit. Therefore, the entrance / exit section 110 may be configured in a manner such that the opening / closing section 111K is rolled up, for example.

[0025] Alternatively, if the opening / closing section 111K and the door stop section 111T are assumed to be about 2 m high, the top 1 m 50 cm or so can be a zipper and the bottom 50 cm or so can be a combination of magnetic material and a magnetic sheet, and the handle 110H can also be provided or not, depending on the need.

[0026] In addition, as shown in Figure 3, the door engagement portion 111J can be provided with two rows of hook-and-loop fasteners, one above the other, on each of the opening / closing portion 111K and the door stop portion 111T, allowing one or more hook-and-loop fasteners BT to be selectively used, thereby adjusting the engagement force between the opening / closing portion 111K and the door stop portion 111T and responding to cases where the engagement force has deteriorated.

[0027] That is, for example, as shown in Figure 3, by covering some (two in the figure) of the four hook-and-loop fasteners BT1 to BT4 with covers BTC2 and BTC3 (white areas in the figure), it is possible to adjust the engagement force at the engagement portion.If the engagement force of hook-and-loop fasteners BT1 and BT2 decreases due to deterioration over time, etc., it is possible to remove covers BTC2 and BTC3, etc., so that the hook-and-loop fasteners BT2 and BT3 that were not in use can be used, thereby maintaining or restoring the engagement force at door engagement portion 111J.

[0028] Next, the window portion 130 of the main housing 100 is a portion constituting a window made of any translucent or transparent material that allows for some degree of visibility into the interior. Such a window portion 130 is provided for the purposes of checking whether or not a user is present in the room through the main housing 100, checking the usage status and safety of the interior of the main housing 100 from the outside of the main housing 100, or labor management. Therefore, in the examples of Figures 2 and 3, the window portion 130 constitutes the upper half of the entrance / exit portion 110, but is not limited to this, and it is also possible to provide a window on another side of the main housing 100, and the size and number of the window portion 130 can also be set as desired.

[0029] Next, an air supply duct 500 and a circulation duct 700 can be arranged or connected to the side surface of the main housing 100.

[0030] Of these, the air supply duct 500 is a part that functions as a passage for supplying temperature-controlled air from a spot air conditioner 900 disposed inside the sub-housing 300 (described later) into the main housing 100 .

[0031] The circulation duct 700 is a part that functions as a passage for sending the air inside the main housing 100 into the sub-housing 300 .

[0032] Therefore, the air supply duct 500 and the circulation duct 700 have a cylindrical shape made of a flexible material, and the material may be the same as the membrane material that forms the main housing 100 and the sub-housing 900, or may be made of a lightweight material with high thermal insulation properties that is different from the membrane material. Also, a reinforcing material may be provided inside to maintain a certain degree of shape.

[0033] The air supply duct 500 and the circulation duct 700 are basically connected to the upper side of the main housing 100, and the circulation duct 700 is connected to the lower side, but as long as the above-mentioned purpose can be achieved, it basically does not matter how they are arranged or connected to the main housing 100 and the sub-housing 300.

[0034] Therefore, for example, as a method of connecting the air supply duct 500, or the circulation duct 700, or both, to the main housing 100, etc., it is possible to adopt a configuration in which one end is sewn to the side of the main housing 100 or the side of the sub-housing 300.

[0035] As an example of this, for example, as shown in FIG. 4, it is possible to sew an air supply duct 500 around the main housing side intake duct opening 150 of the main housing 100.

[0036] Here, Figure 4(A) is a partial cross-sectional view showing an example in which one end of the air supply duct 500 is sewn around the main housing side intake duct opening 150 of the main housing 100, and Figure 4(B) is a side view including a partial cross-sectional view showing an example in which the other end of the air supply duct 500 connected to the main housing 100 in this manner is inserted into the air supply duct opening 350 of the sub-housing 300, and the air supply opening 920 of the spot air conditioner 900 inside the sub-housing 300 is inserted inside the cylindrical shape formed by the air supply duct 500.

[0037] In the example shown in Figure 4, the other end of the air supply duct 500 that is not sewn to the main housing 100 is a free end 500F, which can be inserted into the sub-housing 300 and used.

[0038] Furthermore, when such a free end 500F is provided, as shown in FIG. 5(A), a tube T with a notch in one part can be provided near the end of the free end 500F so as to surround the air supply duct 500, and a string C can be passed through the inside of the tube T, and both ends of the string C can be taken out from the notch to create a binding section Cp for binding.As shown in FIG. 5(B), the air supply port 920 of the spot air conditioner inserted inside the air supply duct 500 can be fixed by narrowing the diameter on the free end 500B side.

[0039] Similarly, when one end of air supply duct 500 or circulation duct 700 is formed as a free end in this way, it is also possible to provide a cutout (500FC or 700FC) parallel to the axial direction of the cylindrical shape that constitutes these ducts in part of free end 500F or 700F, and to provide a hook-and-loop fastener BT on the outer circumferential surface of this cutout. In this case, by providing a hook-and-loop fastener BT that can be engaged with each duct opening in main housing 100 or around each duct opening in sub-housing 300, it is possible to stably fix the free end to the side surface of main housing 100 or sub-housing 300.

[0040] 6 shows an example in which a notch 700FC is provided at the free end 700F of the circulation duct 700, and a hook-and-loop fastener BT is provided on the outer peripheral surface of the notch 700FC. Therefore, by adopting such a configuration, even if a free end (500F, 700F) is provided at one end of the air supply duct 500 or the circulation duct 700, it is possible to stably hold one end of the air supply duct 500 or the circulation duct 700 on the side surface of the main housing 100 or the sub-housing 300. Note that although FIG. 6 shows a duct with a rectangular cross section, the present invention does not particularly limit the shape of the duct as long as the interior is cylindrical and has ventilation.

[0041] Furthermore, in the example of FIG. 6, a locking device LDA is provided on the other end side of the circulation duct 700 that is different from the free end 700F side.

[0042] 7, the locking device LDA can be selectively provided at one or both ends of the circulation duct 700 or the air supply duct 500, and by providing a locking device (duct opening locking device) LDB that can lock with the locking device LDA at various duct openings of the main housing 100 or the sub-housing 300, it is possible to easily connect each duct to the main housing 100 or the sub-housing 300. The structure of such locking devices (LDA, LDB) is not particularly limited as long as they can perform their functions, and so, for example, they may be of a type that is screwed in while rotating, as exemplified by the dotted arrow in Fig. 7(A), or they may have a mutually fitting structure, as exemplified by the dotted arrow in Fig. 7(B).

[0043] Furthermore, when the fastening device LDA is provided on the main housing 100 or the sub-housing 300 in this way, or when, for example, an air supply duct 500 or a circulation duct 700 that is sewn to the main housing 100 is inserted into the sub-housing, or when main housing side intake duct openings 150 and main housing side exhaust duct openings 170 are provided on multiple sides of the main housing 100 as described below, there is a possibility that unused openings will occur depending on the usage situation.

[0044] Therefore, if there is a possibility that an opening may not be used depending on the usage conditions, it is possible to provide an opening cover UUC as shown in Figure 8, for example, to seal the unused opening.

[0045] Here, FIG. 8(A) is a perspective view showing an example of use of the opening cover UUC, and FIG. 8(B) is a cross-sectional view thereof.

[0046] The opening cover UUC has a shape and area large enough to cover the various duct openings of the main housing 100 (or sub-housing 300), and is provided with hook-and-loop fasteners BT around its periphery. Therefore, if hook-and-loop fasteners BT that engage with the opening cover UUC are provided around the various duct openings of the main housing 100 (or sub-housing 300), when there are unused duct openings, the hook-and-loop fasteners can be engaged with each other to seal off the duct openings.

[0047] Next, as described above, main housing side air supply duct opening 150 and main housing side exhaust duct opening 170 are provided on at least one side of main housing 100, but these duct openings are not limited to being provided on one side, and can also be provided on each side of main housing 100, as illustrated in FIG. 9.

[0048] Here, Figure 9 shows an example in which a main housing side air supply duct port 150 and a main housing side exhaust duct port 170 are provided on each side of the main housing, Figure 9(A) is a top view including a partial perspective view, Figure 9(B) is a front view including a partial perspective view, and Figure 9(C) is a side view including a partial perspective view.

[0049] That is, although the present invention has a basic configuration in which sub-housing 300 is placed adjacent to main housing 100, depending on the environment in which they are placed, if main housing side air supply duct opening 150 and main housing side exhaust duct opening 170 are provided on only one side, the degree of freedom in placement may be limited, and it may not be possible to place them. Also, since a single spot air conditioner is generally placed inside sub-housing 300, in some cases it may be desired to connect multiple sub-housings 300 to main housing 100 to improve the temperature control capacity of main housing 100.

[0050] Therefore, in order to deal with such a case, the present invention can also employ a configuration in which a plurality of sub-housings 300 can be connected to the main housing 100, as described above.

[0051] Therefore, although the sub-housing 300 is arranged on the right side of the main housing 100 illustrated in Figure 1 or Figure 2, it is also possible to arrange the sub-housing 300 by providing a main housing side air supply duct opening 150 and a main housing side exhaust duct opening 170 on the left side or back of the main housing 100, as shown in Figures 9(A) and (B), for example.

[0052] Although Figures 9(B) and (C) show an example in which there are two main housing side air supply duct openings 150, one above the other, in the present invention, it is also possible to provide multiple main housing side air supply duct openings 150 in this manner depending on the type of spot air conditioner to be placed inside the sub-housing 300.

[0053] Next, a description will be given of the shape-retaining band 190 of the main housing 100. The shape-retaining band 190 is a strip-shaped region formed on the lower end side of the film material that constitutes the main housing 100.

[0054] In the spot air conditioning booth of the present invention, the lower end of the main housing 100 is an open end, but such an open end generally causes some of the air introduced into the main housing 100 to leak out. As a result, some of the leaking air may vibrate or flutter the lower end of the main housing 100, and if this phenomenon occurs, the appearance and usability of the spot air conditioning booth may be impaired.

[0055] Therefore, in the present invention, a shape-retaining band 190 is provided to prevent vibrations and the like from occurring at the bottom end of the main housing 100.

[0056] In accordance with the above-mentioned purpose, shape-retaining band 190 is formed by folding a film material at the bottom end of main housing 100, forming folded portion 191 and sewing it with thread TH or the like, as shown in FIG. 10(A), or by folding a film material multiple times at the bottom end of main housing 100, forming multi-folded portion 193 and sewing it with thread TH or the like, as shown in FIG. 10(B), to stabilize the bottom end. In some cases, it is also possible to employ a configuration in which a plastic plate or the like is inserted inside such a folded portion. Therefore, in the present invention, by providing such shape-retaining band 190, it is possible to effectively prevent vibrations and flapping that occur at the bottom end of main housing 100.

[0057] As described above, the circulation duct 700 is basically provided below the air supply duct 500 and below the main housing 100 to the sub-housing 300, but a part or all of the circulation duct 700 may be connected to the shape-retaining band 190. In that case, the presence of the circulation duct 700 serves to damp vibrations in that area.

[0058] Next, a roof unit 400 that can be connected to the main housing 100 or the sub-housing 300 of the present invention will be described.

[0059] In the present invention, the shapes of the main housing 100 and the sub-housing 300 are basically polygonal prisms such as quadrilaterals, and the shape of the ceiling (or roof) portion may be configured to be flat, or in some cases, it is possible to configure a roof shape in advance in which the upper part of the front side where the entrance / exit section 110 and the loading / unloading section 310 are provided is high and the rear side is low, with the ceiling portion formed as a slope.

[0060] Furthermore, when the spot air conditioning booth according to the present invention is used indoors, rainfall or the like is not expected on the ceiling, so such a roof structure is not particularly necessary, and therefore a roof structure with such a slope is not necessarily required.

[0061] On the other hand, however, depending on the location of normal use and the usage conditions, it may be beneficial to provide a roof structure, and even if the ceiling portion is formed horizontally, if a roof shape can be added as needed, it is possible to further improve convenience in use.

[0062] Therefore, in the present invention, it is also possible to configure the roof unit 400 so that it can be connected to the ceiling portion of the main housing 100 or the sub-housing 300.

[0063] Such a roof unit 400 is a lid body having a frame body of a height such that an inclined surface is formed on the upper surface 410 and the side surface 430 forms the inclined surface with respect to the horizontal plane, as illustrated in FIG. 11, and is configured to be connectable to the top of the main housing 100 (or sub-housing 300).

[0064] Here, Figure 11 is an oblique view illustrating an example of engaging and positioning the roof unit 400 on the main housing 100, where Figure 11(A) shows the state before the roof unit is connected, and Figure 11(B) is an oblique view showing the state after the roof unit 400 has been lowered as indicated by the dotted arrow in Figure 11(A) and engaged with the respective engaging portions of the roof unit 400 and main housing 100.

[0065] As illustrated in Figure 12, roof unit side engagement portions 430J are provided at the corners of the frame body 430 of the roof unit 400, and frame side engagement portions FJ are provided at the upper end of the frame of the main housing 100 corresponding to these.These can be engaged by lowering the roof unit 400 as indicated by the dotted arrow in the figure, and the roof unit 400 can be connected to the top of the main housing 100 (or sub-housing 300) as shown in Figure 11(B).

[0066] The shape of the two engaging portions (430J, FJ) for the roof unit 400 is not particularly limited, and any type can be adopted. For example, in the case of a type in which the convex portion of the roof unit side engaging portion 430J engages with the concave engaging portion FJ on the top of the frame of the main housing 100, etc., as shown in Figure 12, it is also possible to form in advance a lid portion 193 using a part of the membrane material that constitutes the main housing 100 and a hook-and-loop fastener BT.

[0067] In addition, the roof unit 400 may be provided with a connector 450 for connecting a support cable SC to the roof unit side engagement portion 430J or any other location.In such a case, as illustrated in Figure 13, it is also possible to use an appropriate peg P or the like to stably hold the main housing 100 (or sub-housing 300) on the ground surface GL via the roof unit 400 using the support cable SC.

[0068] Next, we will explain the sub-housing 300 that constitutes the present invention. As shown in Figures 1 and 2, etc., the sub-housing 300 is another small room connected to the main housing 100 via an air supply duct 500 and a circulation duct 700, and inside it, for example, a spot air conditioner 900 as shown in Figure 14 is placed and stored.

[0069] As shown in FIG. 14, the spot air conditioner 900 has an intake port 910 for taking in outside air, an air outlet 930 for sending out temperature-controlled air, and an exhaust port 950 for expelling heat exchanged with the temperature-controlled air inside. Some models have multiple air outlets, and are generally relatively small and portable.

[0070] Therefore, the sub-housing 300 for housing such a spot air conditioner 900 is smaller than the main housing 100, but has basically the same configuration as the main housing 100, and is formed from a frame that holds each side of the sub-housing 300 from the inside and a membrane material that is provided on the outer surface of the frame.

[0071] An entrance / exit section 310 is provided on the front side of the sub-housing 300 for carrying the spot air conditioner 900 into or out of the sub-housing 300, and the entrance / exit section 310 can also be formed by an opening / closing section 311K or a door section 311, etc., similar to the entrance / exit section 110 of the main housing 100.

[0072] In addition, an air supply duct opening 350 and a sub-housing side air intake duct opening 370 are provided on the side of the sub-housing 300 (for example, the left side as illustrated in Figure 1, etc.) to connect to the main housing 100 via an air supply duct 500 and a circulation duct 700.

[0073] Of these, air supply duct opening 350 is a portion that connects air supply duct 500 that functions as a passage for supplying temperature-controlled air from air supply opening 910 of the spot air conditioner to the main housing 100 side.

[0074] Therefore, when the air supply duct 500 is connected to the main housing 100, the connection between the air supply duct opening 350 and the air supply opening 910 of the spot air conditioner can be determined according to the shape of the air supply duct 500 on the sub-housing 300 side. Therefore, for example, when the air supply duct 500 has a free end 500F, the tip of the air supply opening 930 of the spot air conditioner can be passed through the inside of the free end 500F for connection. When a fastener LDA is formed at the end of the air supply duct 500, the air supply opening 910 of the spot air conditioner can be inserted through the inside of the fastener LDB on the sub-housing side to introduce temperature-controlled air into the main housing. Alternatively, when the air supply duct 500 is sewn to the air supply duct opening 350 on the sub-housing 300 side, the air supply opening 910 of the spot air conditioner can be inserted inside the air supply duct 500 to introduce temperature-controlled air into the main housing.

[0075] The height and position of the air supply duct 350 provided in the sub-housing 300 are determined with an eye to the surface adjacent to the main housing 100, such as the left side of the sub-housing 300, taken into consideration, and are determined taking into account the shape of the spot air conditioner 900 that is expected to be placed in the sub-housing 300. Therefore, the main housing-side intake duct opening 150 of the main housing 100 and the air supply duct opening 350 of the sub-housing 300 are basically arranged to face each other, but since the main housing 100 and the sub-housing 300 are connected via the air supply duct openings, there is a degree of freedom in their placement, and therefore, for example, as illustrated in Fig. 15, the positions of the main housing-side intake duct opening 150 of the main housing 100 and the air supply duct opening 350 of the sub-housing 300 may be offset in the vertical direction.

[0076] In addition, the sub-housing side intake duct port 370, which is provided on the side of the sub-housing 300 (for example, the left side as illustrated in Figure 1, etc.) in the same manner as the air supply duct port 350, is a part that connects to a circulation duct 700 that functions as a passage for supplying temperature-controlled air from inside the main housing 100 to the sub-housing 300 side.

[0077] In the present invention, the temperature-controlled air in main housing 100 is returned to sub-housing 300 and circulated, thereby preventing the temperature of spot air conditioner 900 in sub-housing 300 from rising, enabling efficient operation. This movement of air from main housing 100 to sub-housing 300 is achieved by operating spot air conditioner 900 located in sub-housing 300, which draws air from air inlet 910 of the spot air conditioner, creating a negative pressure inside sub-housing 300.

[0078] In addition, the connection between the circulation duct 700 at the sub-housing side intake duct port 370 is basically the same as when connecting the air supply duct 500 to the air supply duct port 350, and various options are possible depending on the type of end of the circulation duct 700 to be connected.

[0079] Furthermore, it is desirable that the positions of the intake duct port 370 on the sub-housing side and the exhaust duct port 170 on the main housing side be configured so that they are basically opposite each other, but as mentioned above, these are connected via the circulation duct 700, so it is possible to ensure a certain range of freedom.

[0080] Next, the sub-housing 300 is configured to have a sub-housing exhaust duct port 390 on a side surface opposite to the side surface on which the air supply duct port 350 and the sub-housing intake duct port 370 are provided.

[0081] The secondary housing side exhaust duct opening 390 is a part that has the function of guiding and discharging the exhaust heat from the exhaust opening of the spot air conditioner 900, and a duct opening cover 393 or the like can be provided on the outer surface of the secondary housing side exhaust duct opening 390 to improve exhaust efficiency and protect from wind and rain.

[0082] The connection between the sub-housing side exhaust duct opening 390 and the exhaust opening of the spot air conditioner 900 can be made by extending the exhaust opening 950 portion of the spot air conditioner 900 in the direction of the sub-housing side exhaust duct opening 390.

[0083] Furthermore, as shown in FIG. 16, the air supply port 930 and the air exhaust port 950 of the spot air conditioner 900 arranged in the sub-housing 300 may be provided with an air vent 330 inside the air supply duct port 350 of the sub-housing 300 or the air exhaust duct port 390 on the sub-housing side, or inside both of these, and the air may be circulated by inserting each of them into the air vent 330.

[0084] 16 is a front view including a partial perspective view that schematically shows the connection relationship between the air supply port 930 and the exhaust port 950 of the spot air conditioner when the air supply duct 330 is provided inside the sub-housing 300.

[0085] The air supply duct 330 illustrated in FIG. 16 is basically cylindrical, similar to the air supply duct 500 illustrated in FIGS. 4 and 5, and as illustrated in FIGS. 4 and 5, one end can be sewn to the inside of the membrane material constituting the sub-housing 300, or a fastener LDA or LDB can be provided inside the sub-housing 300 or at the end of the air supply duct 330 as appropriate. Therefore, by adopting such a configuration, it is possible to store the ends of the air supply port 930 or the air exhaust port 950 of a spot air conditioner inside the cylindrical shape of the air supply duct 330, tie them with string C or the like to reduce the diameter, seal the ends, and prevent leakage of the air flowing through. Therefore, by using such an air supply duct 330, it is possible to ensure the necessary air movement path.

[0086] With the spot air conditioning booth of the present invention having the above-mentioned configuration, by returning a portion of the temperature-controlled air in the main housing to the sub-housing, it is possible to suppress temperature changes caused by rises and falls in the temperature of the spot air conditioner in the sub-housing, prevent a decrease in the operating efficiency of the spot air conditioner, and efficiently guide the airflow of cool or warm air from the spot air conditioner into the main housing, making it even easier to control the temperature in the main housing using the spot air conditioner.

[0087] The above configuration is an example of the configuration of the spot air conditioning booth according to the present invention, and the configuration can be changed as desired within the scope of the spirit of the present invention.

[0088] Therefore, for example, the appearances of the main housing 100 and the sub-housing 300 can be selected arbitrarily within the scope of the spirit of the present invention, and the configurations described for the main housing 100 can also be applied to the sub-housing 300 as appropriate.The shape of the end or both ends of the air supply duct 500 can also be reflected in the configurations of the circulation duct 700, ventilation duct 330, etc. as appropriate, or vice versa.
