[0003] [Patent Document 1] Japanese Patent Publication No. 2023-018760 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] In homes with a central air conditioning system, the interior is always heated in winter, so laundry that is hung to dry indoors has the advantage of drying in a relatively short time.

[0005] On the other hand, in homes equipped with central air conditioning systems, drying laundry indoors in the summer can cause moisture from the laundry to spread widely throughout the house, raising the risk of the interior of the house becoming uncomfortable due to increased humidity. Furthermore, the increased humidity can increase the amount of latent heat processed by the air conditioner, which increases the frequency of operation of the air conditioner, resulting in a new problem of increased operating noise.

[0006] The present invention was devised in consideration of the above problems, and its main object is to provide a house that can reduce the discomfort caused by humidity and the operating noise of air conditioners even when drying laundry indoors in the summer. [Means for solving the problem]

[0007] The present invention is a house comprising a plurality of living rooms, a chamber box having a first inlet and having an air conditioner indoor unit inside, a duct having one end connected to the chamber box and the other end connected to the plurality of living rooms, a fan for pressurizing the conditioned air in the chamber box through the duct to the plurality of living rooms, and a drying chamber defining a drying space for hanging out laundry, the drying chamber having a second inlet for drawing in air and a second outlet directly connected to the first inlet of the chamber box. [Effects of the Invention]

[0008] By adopting the above-described configuration, the house of the present invention can reduce discomfort caused by humidity and operating noise of the air conditioner even when drying laundry indoors in summer. [Brief explanation of the drawings]

[0010] An embodiment of the present invention will now be described with reference to the drawings. The drawings include exaggerated representations and representations that differ from the dimensional ratios of the actual structures to facilitate understanding of the present invention. Furthermore, when there are multiple embodiments, identical or common elements are designated by the same reference numerals throughout the specification, and redundant explanations are omitted. Furthermore, the specific configurations shown in the embodiments and drawings are intended to aid in understanding the contents of the present invention, and the present invention is not limited to the specific configurations shown in the drawings.

[0011] 1 is a cross-sectional view conceptually illustrating a house 1 according to one embodiment of the present invention. The house 1 according to this embodiment includes an underfloor space 2 and an above-floor space 3, and is, for example, an industrialized house with high airtightness.

[0012] The underfloor space 2 is, for example, a space surrounded by a foundation 4 insulated with a heat insulating material. A plurality of living rooms 5 are provided in the above-floor space 3. In this embodiment, the plurality of living rooms 5 includes a living room 5A on the first floor and a living room 5B on the second floor. In other embodiments, the house 1 may be a single-story house or may have three or more floors.

[0013] The house 1 of this embodiment is provided with a central air-conditioning system 6.

[0014] The central air-conditioning system 6 of this embodiment includes, for example, a chamber box 7, a duct 8, a fan 9, and a control device 12.

[0015] [Chamber box] FIG. 2 is an enlarged cross-sectional view conceptually showing the chamber box 7. As shown in FIG. 2, the chamber box 7 is formed in a box shape that defines a space inside. The chamber box 7 of this embodiment has a side wall 71, an upper wall 72, and a lower wall 73, and is formed in a substantially rectangular parallelepiped shape. The chamber box 7 also has a first inlet 11, through which air inside the house 1 can be taken in. The first inlet 11 of this embodiment is formed, for example, in the upper part of the side wall 71 of the chamber box 7. The first inlet 11 may be provided with, for example, a louver or the like.

[0016] An indoor unit 10A of an air conditioner 10 is provided inside the chamber box 7. The air conditioner 10 of this embodiment is, for example, a heat pump inverter air conditioner for home use, and an outdoor unit (not shown) is provided outside the house 1. The air conditioner 10 communicates with a control device 12, and can perform a predetermined air conditioning operation by inputting information such as whether to cool or heat and the set temperature. In this embodiment, a partition wall 75 extending vertically is provided inside the chamber box 7, and the indoor unit 10A is fixed to the first inlet 11 side of this partition wall 75.

[0017] The indoor unit 10A of this embodiment includes an inlet 101 located on the upper side of its housing, an outlet 102 located on the lower side of the housing, a heat exchanger 103 therebetween, and an indoor unit fan 104 for blowing out the air that has undergone heat exchange in the heat exchanger 103 from the outlet 102. Therefore, the indoor unit 10A can draw in air taken in from the first inlet 11 of the chamber box 7 through the inlet 101, exchange heat in the heat exchanger 103, and blow out conditioned air Ac (hereinafter referred to as conditioned air Ac) from the outlet 102. As a result, the conditioned air Ac is supplied to the outlet 102 side of the indoor unit 10A (the space below the chamber box 7) within the chamber box 7. The chamber box 7 may be provided with a separate outside air inlet (not shown) or the like for taking in outside air.

[0018] [duct] The duct 8 of this embodiment is a means for supplying the conditioned air Ac in the chamber box 7 to a plurality of rooms 5. In this embodiment, the duct 8 includes a first duct 8A that supplies the conditioned air Ac to a room 5A on the first floor, and a second duct 8B that supplies the conditioned air Ac to a room 5B on the second floor (these ducts 8A and 8B are collectively referred to simply as "duct 8"). One end of the duct 8 is connected to the chamber box 7. Specifically, one end of the duct 8 is located inside the chamber box 7. The other end of the duct 8 branches into multiple parts that are connected to the respective rooms 5. A damper (not shown) for adjusting the air volume is provided at the other end of the duct 8. The opening and closing degree of the damper is controlled by a control device 12.

[0019] [fan] The fan 9 is a means for pressurizing and sending the conditioned air Ac in the chamber box 7 to the multiple rooms 5 via the duct 8. In this embodiment, the fan 9 is housed in the chamber box 7, but is not limited to this configuration. The fan 9 in this embodiment includes a first fan 9A connected to the first duct 8A and a second fan 9B connected to the second duct 8B. These fans 9A and 9B are controlled to a predetermined rotation speed by the control device 12. In this way, the conditioned air Ac in the chamber box 7 is supplied to the multiple rooms 5.

[0020] [Drying room] 1 and 2, the house 1 of this embodiment is further provided with a drying room 20. The drying room 20 is a space for drying laundry 40 inside the house 1, i.e., a room that defines a drying space 23. The drying room 20 of this embodiment is defined by a partition wall 24. In one example, the drying room 20 is defined by the partition wall 24, an upper wall 25, and a lower wall 26.

[0021] 3 is a top perspective view of the chamber box 7 and the drying chamber 20. As shown in Fig. 3, the partition wall 24 is provided with, for example, an opening / closing door 27 for users to enter and exit. The size of the drying space 23 may be determined appropriately depending on the number of occupants, the amount of laundry 40, etc.

[0022] The drying chamber 20 has a second inlet 21 for drawing in air from within the house 1, and a second outlet 22 directly connected to the first inlet 11 of the chamber box 7. In this specification, the term "directly connected" is intended to include not only a mode in which the second outlet 22 and the first inlet 11 are directly connected without any separation between them (including a case in which the second outlet 22 serves as both the second outlet 22 and the first inlet 11), but also a mode in which the second outlet 22 and the first inlet 11 are connected so that air discharged from the second outlet 22 is supplied to the first inlet 11 without substantially mixing with other air within the house 1 (see FIG. 4 described below).

[0023] The drying chamber 20 of this embodiment is provided adjacent to the chamber box 7 so that the second outlet 22 of the drying chamber 20 also serves as the first inlet 11 of the chamber box 7. That is, as can be seen from Figures 2 and 3, in this embodiment, the side wall 71 of the chamber box 7 and the partition wall 24 of the drying chamber 20 have a shared side wall 50. Therefore, the drying chamber 20 of this embodiment is formed as a front room of the chamber box 7 of the central air-conditioning system 6, that is, as a room adjacent to the chamber box 7 on the upstream side in the air flow direction.

[0024] [Operation of this embodiment] When the central air conditioning system 6 is operated in the summer, conditioned air Ac (cooled air) is generated in the chamber box 7 by the indoor unit 10A of the air conditioner 10. This conditioned air Ac is supplied to each living room 5 via the fan 9 and the duct 8. In this way, each living room 5 is cooled.

[0025] Furthermore, operation of the fan 9 creates a negative pressure inside the chamber box 7, and air from inside the house 1 is taken into the chamber box 7 through the first inlet 11. At this time, since the first inlet 11 is directly connected to the second outlet 22 of the drying chamber 20, air that has passed through the drying space 23 is drawn into the first inlet 11 from the second inlet 21 of the drying chamber 20. This generates an airflow in the drying space 23 and helps to accelerate the drying of the laundry 40.

[0026] The humidity in the drying space 23 taken into the chamber box 7 is partially drained by the heat exchanger 103 of the indoor unit 10A. This allows the highly humid air in the drying space 23 to be dehumidified in the chamber box 7 and supplied to each living room 5. Therefore, according to the house 1 of this embodiment, the humidity released from the laundry 40 in the drying chamber 20 does not directly diffuse into the living rooms 5 and the like in the house 1, thereby preventing the interior of the house 1 from becoming uncomfortable due to humidity.

[0027] The indoor unit 10A of the air conditioner 10 has an increased amount of latent heat processed from the high-humidity air from the drying space 23, which increases the frequency of operation of the indoor unit 10A and may result in increased operating noise. However, because the first inlet 11 of the chamber box 7 and the second outlet 22 of the drying chamber 20 are directly connected, some of the operating noise generated inside the chamber box 7 is absorbed by the drying space 23 and the laundry 40 hung out to dry there before being transmitted to the living rooms 5, etc. This reduces the operating noise of the indoor unit 10A of the air conditioner 10 heard in each living room 5.

[0028] As described above, the house 1 of this embodiment can reduce discomfort caused by humidity and reduce the operating noise of the air conditioner 10 even when drying laundry indoors in summer.

[0029] [Preferred embodiment] Preferred embodiments of the present invention will be described below. All of the following embodiments should be understood as optional configurations.

[0030] The effective opening area of ​​the second inlet 21 of the drying chamber 20 is not particularly limited, but if it is too small, pressure loss will increase when air is taken into the chamber box 7, which may impair the air conditioning function of the central air conditioning system 6. In order to suppress such pressure loss, it is desirable that the effective opening area of ​​the second inlet 21 be at least twice the effective opening area of ​​the first inlet 11 of the chamber box 7. There is no particular upper limit to the effective opening area of ​​the second inlet 21, but it may be, for example, four times or less the effective opening area of ​​the first inlet 11 of the chamber box 7.

[0031] The position of the second inlet 21 of the drying chamber 20 is not particularly limited, but is desirably located lower than the second outlet 22, as shown in FIG. 2. In this embodiment, the second inlet 21 is provided below the drying chamber 20, while the second outlet 22 (first inlet 11) is provided at the top of the chamber box 7. By providing the second inlet 21 below the first inlet 11, an airflow F directed from bottom to top as indicated by the arrow in FIG. 2 can be generated in the drying space 23. This rising airflow F collides with the bottom of the laundry 40, thereby effectively drying moisture that tends to accumulate at the bottom of the laundry 40 due to gravity.

[0032] As shown in FIG. 3 , in a top perspective view of the drying chamber 20, a clothes drying device 30 for drying laundry 40 is preferably provided on a line L connecting the second entrance 21 and the second exit 22 of the drying chamber 20. Here, line L is a line connecting the centroid C1 of the second entrance 21 and the centroid C2 of the second exit 22. Here, "drying laundry 40 on line L" means that the line L intersects with the laundry 40 in the top perspective view of FIG. 3 . This arrangement allows the airflow to effectively collide with the laundry 40 in the drying space 23, which ultimately helps to dry the laundry 40 quickly. The clothes drying device 30 of this embodiment consists of a clothes drying bar extending horizontally above the drying space 23, on which laundry 40 can be hung via hangers. As the clothes drying fixture 30, various devices can be used instead of a clothes drying bar, as long as they can hang out laundry 40 hung on hangers.

[0033] It is desirable to provide a humidity-regulating material 29 on at least a portion of the partition wall 24 of the drying chamber 20 on the drying space 23 side. The humidity-regulating material 29 can absorb and remove moisture generated in the drying space 23, thereby further reducing the discomfort caused by high humidity associated with indoor drying and the operating noise associated with an increase in the latent heat processing capacity of the air conditioner 10. For example, the humidity-regulating material 29 may be a porous material such as diatomaceous earth, as well as building materials or sheet materials using wood, plaster, tempered gypsum, etc. The humidity-regulating material 29 as described above may also be used on the upper wall 25 and lower wall 26 of the drying chamber 20.

[0034] It is desirable that at least a portion of the partition wall 24 of the drying chamber 20 be formed from a building material having a sound transmission loss rating of Rr-35 or higher according to JIS A1419-1. Forming at least a portion of the partition wall 24 of the drying chamber 20 from such a building material improves the sound insulation of the drying chamber 20. As a result, sound propagated from the chamber box 7 to the drying chamber 20 is effectively prevented from leaking to the outside, further reducing the operating noise of the indoor unit 10A.

[0035] FIG. 4 is an enlarged cross-sectional view conceptually illustrating the chamber box 7 and the drying chamber 20 as another embodiment of the house 1 of the present invention. In this embodiment, the chamber box 7 and the drying chamber 20 are not directly adjacent to each other, but the second outlet 22 of the drying chamber 20 is connected to the first inlet 11 of the chamber box 7 via a connecting duct 60. In this embodiment, when the central air-conditioning system is operated, air inside the house 1 is sucked in through the second inlet 21 of the drying chamber 20 via the drying space 23, the second outlet 22, and the connecting duct 60 before being taken into the chamber box 7 through the first inlet 11 of the chamber box 7. Therefore, the highly humid air in the drying space 23 can be supplied to the first inlet 11 without substantially mixing with other air inside the house 1, and the same functions and effects as those of the previous embodiment can be expected.

[0036] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above specific disclosure, and can be implemented in various modified forms within the scope of the technical idea described in the claims.
