Description

[Technical Field]

[0001] The present invention relates to a dehumidifying structure and a dehumidifier arrangement structure for a building in which a pipe space is arranged adjacent to an indoor space. [Background technology]

[0002] In business hotels, the air conditioning and ventilation design often uses room air conditioners and a Type 3 ventilation system (natural air intake from the guest room walls, mechanical exhaust from the bathroom). In this case, the humidity in the indoor space of the guest room becomes constant, and during the rainy season and summer (hereinafter referred to as "summer"), the indoor environment can become uncomfortable with a relative humidity of 70% or more.

[0003] Common countermeasures include installing an outdoor air conditioning unit (supplying dehumidified air) or using a room air conditioner with a reheat dehumidification function, but because these have issues such as being expensive, a simpler measure such as placing a small household dehumidifier in each indoor space is sometimes adopted.

[0004] From the viewpoint of storing a small dehumidifier, there is a technique of installing a dehumidifier on the back panel of a wooden storage device such as a chest of drawers (Japanese Patent Laid-Open Publication No. 2002-10840 (Patent Document 1)). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-10840 Summary of the Invention [Problem to be solved by the invention]

[0006] The interior space of a business hotel guest room is narrow, with the entrance space adjacent to the entrance and the bed space integrated into one space, so it can be difficult to find space to install a dehumidifier, even if it is a small one. Also, if a dehumidifier is installed in the interior space, consideration must be given to its operating noise.

[0007] Furthermore, in the summer, humidity can rise not only in the indoor space but also in the attic space. In such cases, if the indoor space is air-conditioned at a low temperature, there is a risk of condensation and mold forming on the ceiling. The above-mentioned measures to dehumidify the indoor space cannot dehumidify the attic space. Therefore, installing a commercial dehumidifier in the attic space is one option, but the specifications are excessive for the size of the guest room, and consideration must also be given to the operating noise.

[0008] The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a dehumidification structure and a dehumidifier placement structure that can cheaply and easily dehumidify both the indoor space and the attic space without narrowing the indoor space. [Means for solving the problem]

[0009] A dehumidifying structure according to one aspect of the present invention is a dehumidifying structure for a building in which a pipe space is arranged adjacent to an indoor space, and includes a dehumidifier installed in a dehumidifier accommodating space formed in the pipe space and communicating with the attic space, an intake port provided in a first partition wall separating the pipe space from the indoor space for taking in air from the indoor space into the dehumidifier accommodating space, and an outlet port provided in the first partition wall for blowing air dehumidified by the dehumidifier into the indoor space.

[0010] Preferably, the dehumidifying structure further includes a first shielding member capable of opening and closing an opening that connects the dehumidifier accommodating space and the attic space, and a second shielding member capable of opening and closing the air outlet.

[0011] It is desirable that the first shielding member and the second shielding member are integrally formed by a slide cover that is continuously movable in the vertical and depth directions when viewed from the indoor space.

[0012] Preferably, the pipe space is disposed adjacent to the water-related space. In this case, it is desirable that the dehumidifying structure be provided in a second partition wall that separates the pipe space from the water-related space, and further include a drain port for discharging drainage water from the dehumidifier into the water-related space.

[0013] Preferably, the first partition wall includes a first wall portion facing the bed space of the indoor space and provided with an intake port, and a second wall portion facing the entrance space of the indoor space and provided with an outlet port.

[0014] It is also desirable to provide an air conditioner intake on the ceiling of the entrance space.

[0015] A dehumidifier placement structure according to one aspect of the present invention is a dehumidifier placement structure in a building in which a pipe space communicating with the attic space is placed adjacent to an indoor space, and is characterized in that a dehumidifier storage space is partitioned within the pipe space, and an intake port for taking air from the indoor space into the dehumidifier storage space and an outlet port for blowing air dehumidified by the dehumidifier into the indoor space are drilled in the partition wall separating the pipe space from the indoor space, making it possible to place a dehumidifier in the dehumidifier storage space. [Effects of the Invention]

[0016] According to the present invention, it is possible to inexpensively and easily dehumidify both the indoor space and the attic space without narrowing the indoor space. [Brief explanation of the drawings]

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals and description thereof will not be repeated.

[0019] <Overview of the configuration> The general configuration of the dehumidifying structure according to this embodiment will be described with reference to Figures 1 to 3. Figure 1 is a plan view showing the general configuration of the dehumidifying structure. Figure 2 is a cross-sectional view showing the general configuration of the dehumidifying structure, taken along line II-II in Figure 1. Figure 3 is a perspective view showing the dehumidifier accommodating space 131 in the pipe space 130. Arrow A1 in Figure 1 etc. indicates the depth direction as seen from the entrance (doorway) of the guest room, and arrow A2 indicates the left-right direction of the guest room.

[0020] First, a brief description will be given of an example of the layout of a guest room in a business hotel to which the dehumidifying structure according to this embodiment is applied. As shown in Fig. 1, the guest room has an indoor space 110 and a wet area space 120. The planar shape of the guest room is typically rectangular, and in general, the wet area space 120 is located at the corner on the side of a common corridor 190, and the indoor space 110 is arranged in an L-shape so as to surround the wet area space 120.

[0021] The indoor space 110 is a space whose temperature can be adjusted by conditioned air from an air conditioner (air conditioner) 81. The indoor space 110 includes an entrance space 111 located in front of the entrance and a bed space 112 in which a bed is placed. The air conditioner 81 is installed, for example, on the side of a dropped ceiling, facing the bed space 112. The wet space 120 is typically a unit bath or bathroom. The indoor space 110 is typically ventilated by a type 3 ventilation system, in which outside air is supplied to the indoor space 110 through a natural air intake port provided in an exterior wall or the like, and is exhausted by an exhaust fan (not shown) provided in the wet space 120.

[0022] In this embodiment, a pipe space 130 is arranged between a water-related space 120 and an indoor space 110 that are adjacent to each other in the left-right direction. The pipe space 130 is surrounded by a wall on the side of the common corridor 190, an L-shaped partition wall (hereinafter referred to as the "first partition wall") 21 facing the indoor space 110, and a linear partition wall (hereinafter referred to as the "second partition wall") 22 facing the water-related space 120.

[0023] The first partition wall 21 is a wall that separates the pipe space 130 from the indoor space 110, and is composed of two wall portions 211, 212 that are perpendicular to each other. One wall portion 211 is parallel to the second partition wall 22 and faces the entrance space 111. The other wall portion 212 is perpendicular to the second partition wall 22 and is disposed facing the bed space 112. The second partition wall 22 is a wall that separates the pipe space 130 from the bathroom space 120.

[0024] As shown in Fig. 2, the pipe space 130 communicates with a ceiling space 140 in the guest room. Note that in Fig. 2, illustration of piping and wiring arranged in the pipe space 130 is omitted.

[0025] The main feature of the dehumidification structure of this embodiment is that a small (household) dehumidifier 5 is installed in the pipe space 130, and this dehumidifier 5 can dehumidify both the indoor space 110 and the attic space 140.

[0026] <Dehumidification structure> A specific example of a dehumidifying structure according to an embodiment of the present invention will be described.

[0027] As shown in Figure 3, the dehumidification structure of this embodiment includes a dehumidifier 5 installed in a dehumidifier accommodating space 131 formed in a pipe space 130, an intake port 41 provided in the first partition wall 21 for taking in air from the indoor space 110 into the dehumidifier accommodating space 131, and an outlet port 42 provided in the first partition wall 21 for blowing out the air dehumidified by the dehumidifier 5 into the indoor space 110.

[0028] The dehumidifier accommodating space 131 is preferably located closer to the bed space 112 in a plan view. The dehumidifier accommodating space 131 is a space partitioned by the wall portions 211, 212 of the first partition wall 21, the second partition wall 22, and a side partition member 31. The side partition member 31 is a plate-like member that divides the pipe space 130 into the dehumidifier accommodating space 131 and a space for piping and wiring. In the vertical direction, the dehumidifier accommodating space 131 is formed between the floor surface of the pipe space 131 and the upper partition member 32. The upper partition member 32 is typically a plate-like member that is arranged horizontally.

[0029] The dehumidifier accommodating space 131 may be large enough to accommodate the dehumidifier 5. As an example, it is assumed that the length and width of the dehumidifier accommodating space 131 are approximately 300 mm x 300 mm, and the height is approximately 800 mm. The height of the dehumidifier accommodating space 131 is set within the range of 500 mm to 1000 mm, for example.

[0030] 1 and 3, in this embodiment, the intake 41 is provided in the wall 212 on the bed space 112 side, and the outlet 42 is provided in the wall 211 on the entrance space 111 side. The walls on which the intake 41 and the outlet 42 are provided may be reversed, or they may be a common wall. Alternatively, the intake 41 and the outlet 42 may be realized by a common opening.

[0031] 2 and 3, an opening 43 is provided in the upper partition member 32, penetrating the upper partition member 32 in the thickness direction (vertical direction). The opening 43 is an outlet for blowing out the air dehumidified by the dehumidifier 5 into the indoor space 110.

[0032] It is desirable that the side partition members 31 extend above the installation height of the upper partition members 32. Specifically, it is desirable that the side partition members 31 are installed upright from floor height to ceiling height within the pipe space 131. This allows the dehumidified air blown out from the openings 43 to be efficiently guided into the attic space 140.

[0033] As described above, the dehumidifier accommodating space 131 communicates with the indoor space 110 via the intake port 41 and the outlet port 42 , and communicates with the attic space 140 via the opening 43 .

[0034] Inlet 41 is typically kept open at all times. On the other hand, outlet 42 and opening 43 are desirably selectively opened. The dehumidifying structure according to this embodiment further includes a first shielding member 43a that can open and close opening 43, and a second shielding member 42a that can open and close outlet 42 (see FIG. 2).

[0035] When the opening 43 is closed (fully closed) by the first shielding member 43a, the dehumidified air by the dehumidifier 5 is blown out (only) from the air outlet 42 into the indoor space 110. As shown in FIG. 2, when the air outlet 42 is closed by the second shielding member 42a, the dehumidified air by the dehumidifier 5 is blown out (only) from the opening 43 into the attic space 140. The blowing direction of the dehumidified air by the dehumidifier 5 can be switched by selectively operating the first shielding member 43a and the second shielding member 42a.

[0036] As shown in Fig. 4, the first shielding member 43a and the second shielding member 42a may be configured by a common sliding lid 45. The sliding lid 45 is disposed in the dehumidifier accommodation space 131, and a handle 450 that protrudes from the air outlet 42 toward the indoor space 110 is provided at the lower end of the sliding lid 45. By moving the handle 450 up and down within the height range of the air outlet 42, the sliding lid 45 can be continuously moved in the vertical direction and the depth direction as viewed from the indoor space 110. Specifically, the sliding lid 45 can be displaced between a first position shown in Fig. 4(A) and a second position shown in Fig. 4(B).

[0037] When the sliding lid 45 is in the first position, the air outlet 42 is fully open and the opening 43 is fully closed. When the sliding lid 45 is in the second position, the air outlet 42 is fully closed and the opening 43 is fully open. By employing such a sliding lid 45, the opening 43 formed at the back of the first partition wall 21 (pipe space 130) can be easily opened and closed from the indoor space 110 side. The sliding lid 45 may be operated by a cleaning staff member in the guest room or automatically by timer management.

[0038] As shown in Figures 2 and 3, the second partition wall 22 is provided with a drain outlet 44 for discharging wastewater from the dehumidifier 5 into the wet space 120. It is desirable that the dehumidifier 5 have a continuous drainage function, and a drain hose 50 of the dehumidifier 5 is inserted into the drain outlet 44. As shown in Figure 2, the floor of the wet space 120 is one step higher than the floor level of the indoor space 110 and the pipe space 130. The drain outlet 44 is provided at a position where it communicates with the drainage space 121 under the floor.

[0039] <Dehumidification method> A dehumidification method using the dehumidification structure according to the embodiment of the present invention will be described.

[0040] When the guest room is in use (during an overnight stay) in the summer, the air outlet 42 is opened as shown in FIG. 4(A), and the dehumidified air from the dehumidifier 5 is blown toward the indoor space 110. In this case, moist air from the indoor space 110 is taken into the dehumidifier accommodating space 131 through the air inlet 41 (indicated by the solid black arrow in FIG. 1), and the dehumidified air from which moisture has been removed by the dehumidifier 5 is blown out from the air outlet 42 into the indoor space 110 (indicated by the hollow arrow in FIG. 1). This makes it possible to reduce the humidity in the indoor space 110. Note that in order to effectively dehumidify the indoor space 110, the air inlet of the dehumidifier 5 and the air inlet 41 may be connected by a pipe or the like.

[0041] When the guest room is not in use (for example, during cleaning), opening 43 is opened as shown in FIG. 4(B), and the dehumidified air from dehumidifier 5 is blown out toward attic space 140. In this case, moist air from indoor space 110 is taken into dehumidifier housing space 131 through intake 41 (indicated by the solid black arrow in FIG. 2), and the dehumidified air from which moisture has been removed by dehumidifier 5 is blown out upward from opening 43 (indicated by the hollow arrow in FIG. 2). Because pipe space 130 and attic space 140 are in communication with each other without a partition, the dehumidified air blown out from opening 43 can efficiently reduce the humidity in attic space 140.

[0042] As described above, the dehumidification structure according to this embodiment makes it possible to prevent condensation and mold not only in the indoor space 110 but also in the attic space 140 using the common dehumidifier 5. Furthermore, since the dehumidifier 5 is installed in the dehumidifier accommodating space 131 in the pipe space 130, the indoor space 110 can be made spacious and the impact of the operating noise of the dehumidifier 5 can be reduced. This improves the comfort of guests.

[0043] Furthermore, the drain hose 50 of the dehumidifier 5 is pulled out to the wet space 120 side, allowing for continuous drainage, eliminating the need to remove water accumulated in the drain tank and allowing the dehumidifier 5 to operate constantly in the summer. As shown in Figure 3, it is desirable to provide an inspection door 46 on the first partition wall 21 to enable inspection of the dehumidifier 5 from the indoor space 110 side.

[0044] Furthermore, in this embodiment, since the air outlet 42 is provided on the entrance space 111 side, it is also possible to remove moisture from the storage cabinet 82 (for example, a clothes rack or a shoe box) installed in the entrance space 111 by using the dehumidified air blown out from the air outlet 42. This is expected to improve the drying speed of the clothes and shoes stored in the storage cabinet 82 and reduce the risk of mold growth.

[0045] Furthermore, in the summer, the temperature of the air dehumidified by the dehumidifier 5 becomes high, but in this embodiment, the air outlet 42 is provided on the entrance space 111 side so that the air is not blown directly into the bed space 112. Therefore, it is possible to reduce the humidity of the entire indoor space 110 while maintaining a good temperature environment in the bed space 112.

[0046] Generally, air can be dehumidified by operating air conditioner 81, so as shown in Fig. 5, air conditioner 81 (or the air intake of air conditioner 81) may be installed on the ceiling near outlet 42 to increase the intake air temperature of air conditioner 81. In this case, the load factor of air conditioner 81 increases, and it can also be expected that the dehumidification capacity of air conditioner 81 will be improved.

[0047] The dehumidifying structure according to the above embodiment can be applied to places other than guest rooms in business hotels, such as employee dormitories and private rooms in nursing homes.

[0048] It is also possible to provide a structure for arranging the dehumidifier 5 that allows the dehumidifier 5 to be installed in the dehumidifier accommodating space 131 in the pipe space 130.

[0049] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims.
