Description

[Technical field]

[0001] The present disclosure relates to air conditioning technology, and more particularly to an air conditioner that performs heating and cooling operations. [Background technology]

[0002] Considering the natural flow of air with a temperature difference, in cooling operation, it is preferable to blow out cold air from above and allow the cold air to naturally fall to cool the room, and then suck in air from below to circulate. In addition, in heating operation, it is preferable to blow out warm air from below to warm the feet while allowing the warm air to rise and then suck in air from above to circulate. In order to perform such operations with one air conditioner, a duct D1 extending upward and a duct D2 extending downward are connected to the air conditioner. In cooling operation, the air conditioner sucks in air from the duct D2 and blows out air from the duct D1. In heating operation, the air conditioner sucks in air from the duct D1 and blows out air from the duct D2 (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-44434 Summary of the Invention [Problem to be solved by the invention]

[0004] Connecting two ducts to an air conditioner makes the configuration complicated. Even to perform cooling and heating operations appropriate for the air flow, it is necessary to keep the configuration from becoming too complicated.

[0005] The present disclosure has been made in consideration of these circumstances, and has as its objective to provide a technology that suppresses the complexity of the configuration while performing operation suited to the air flow. [Means for solving the problem]

[0006] In order to solve the above problems, an air conditioner according to an embodiment of the present disclosure includes a main body case formed of a bottom surface, a top surface facing the bottom surface, and a plurality of side surfaces connected to the bottom surface and the top surface, an air conditioner built into the internal space of the main body case, a single shaft air passage provided on the opposite side of the main body case from the internal space and having a hollow space extending vertically in a portion corresponding to the one side surface, and a control device. The main body case includes a first intake port provided on the top surface side of the one side surface for sucking in air transported from the vertically upward direction of the hollow space, a first outlet port provided on the bottom surface side of the one side surface for transporting the air sucked in from the first intake port vertically downward of the hollow space, a second intake port provided on the top surface side of the one side surface for sucking in air transported from the vertically downward direction of the hollow space, and a second outlet port provided on the bottom surface side of the one side surface for transporting the air sucked in from the second intake port vertically upward of the hollow space. The shaft air passage includes a dividing section that divides the hollow space into an upper air passage and a lower air passage. The upper air passage is connected to the first suction port and the second air outlet to communicate the hollow space with the internal space, and the lower air passage is connected to the second suction port and the first air outlet to communicate the hollow space with the internal space. The control device controls opening or closing of the first suction port, the first air outlet, the second suction port, and the second air outlet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Before specifically describing the embodiments of the present disclosure, an overview of the embodiments will be described. This embodiment relates to an air conditioner that is installed in a facility such as a house and performs whole-building air conditioning for the facility. Warm air rises from the bottom to the top, and cold air falls from the top to the bottom. Considering such air flow, it is desirable that air warmed by the air conditioner be blown out from the bottom of the facility, and air cooled by the air conditioner be blown out from the top of the facility. It is desired to realize such air conditioning while suppressing the complexity of the configuration.

[0011] In this embodiment, a hollow shaft extending in the vertical direction is provided in the facility, and a main body case housing an air conditioner is attached to the shaft. The main body case is provided with a first suction port, a second suction port, a first air outlet, and a second air outlet that can be opened and closed, and by opening at least one of these, the inside of the main body case and the inside of the shaft are communicated. In addition, the inside of the shaft is divided into an upper air duct and a lower air duct by a dividing part. The first suction port and the second air outlet are arranged in the upper air duct, and the second suction port and the first air outlet are arranged in the lower air duct. When performing heating operation, by opening only the first suction port and the first air outlet, the air conditioner warms the air sucked in from the upper air duct and blows the warmed air out from the lower air duct. When performing cooling operation, by opening only the second suction port and the second air outlet, the air conditioner cools the air sucked in from the lower air duct and blows the cooled air out from the upper air duct.

[0012] The examples described below each show a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, the arrangement and connection of the components, as well as the steps (processes) and the order of the steps shown in the following examples are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following examples, those components that are not described in the independent claims showing the highest concept of the present disclosure are described as optional components. In addition, in each figure, the same reference numerals are given to substantially the same configurations, and duplicated descriptions are omitted or simplified.

[0013] 1 shows the configuration of a house 10. The house 10 is a two-story building, and includes an underfloor space 12, a floor surface 14, a first floor room 16, a floor 18, a second floor room 20, a ceiling surface 22, and a small roof 24. In the house 10, the underfloor space 12, the first floor room 16, the second floor room 20, and the small roof 24 are arranged in this order from bottom to top. In addition, the underfloor space 12 and the first floor room 16 are separated by the floor surface 14, the first floor room 16 and the second floor room 20 are separated by the floor 18, and the second floor room 20 and the small roof 24 are separated by the ceiling surface 22.

[0014] A box-shaped main body case 200 is installed in a second floor room 20 of the house 10. An air conditioner (not shown) is arranged inside the main body case 200. The house 10 is provided with a shaft 300 that extends vertically from under the floor 12 to penetrate the small roof 24. The main body case 200 and the shaft 300 are included in the air conditioner 100.

[0015] The shaft 300 is a hollow pipe with a rectangular cross section. For example, in the shaft 300, a heat insulating material is attached to the inner surface of a wooden pipe with a rectangular cross section. The configuration of the shaft 300 is not limited to this. A lower opening 302 at the lower end portion of the shaft 300 is disposed in the underfloor 12, and an upper opening 304 at the upper end portion of the shaft 300 is disposed in the small roof 24. With this configuration, air flows between the underfloor 12 and the small roof 24 through the shaft 300.

[0016] The underfloor space 12 is a hollow space and has a heat insulating material on the inner surface. The underfloor space 12 is connected to the first floor room 16 through an opening (not shown) provided in a part of the floor surface 14. Alternatively, a duct (not shown) may be installed in the underfloor space 12. The duct extends from the lower opening 302 to the floor surface 14 and opens in a part of the floor surface 14.

[0017] The small roof 24 is a hollow space and has a heat insulating material on the inner surface. The small roof 24 is connected to the second floor room 20 through an opening (not shown) provided in a part of the ceiling surface 22. Alternatively, a duct (not shown) may be installed in the small roof 24. The duct extends from the upper opening 304 to the ceiling surface 22 and opens in a part of the ceiling surface 22.

[0018] A staircase (not shown) is provided between the first floor room 16 and the second floor room 20 so as to penetrate the floor 18. With this configuration, air flows between the underfloor space 12 and the small roof 24 through the floor surface 14, the first floor room 16, the floor 18, the second floor room 20, and the ceiling surface 22.

[0019] Air (hereinafter referred to as "first air 600") blown out from the main body case 200 by the operation of the air conditioner flows downward through the shaft 300 and is blown out from the lower opening 302 to the underfloor 12. The first air 600 flows from the underfloor 12 through the floor surface 14, the first floor room 16, the floor 18, and the upper room 20 to the small roof 24. The first air 600 in the small roof 24 is sucked into the shaft 300 from the upper opening 304, flows downward through the shaft 300, and is sucked into the main body case 200. In this way, the first air 600 rises from the underfloor 12 toward the small roof 24.

[0020] Air blown out from the main body case 200 by the operation of the air conditioner (hereinafter referred to as "second air 602") flows upward through the shaft 300 and is blown out from the upper opening 304 onto the small roof 24. The second air 602 flows from the small roof 24 through the ceiling surface 22, the second floor room 20, the floor 18, the first floor room 16, and the floor surface 14 into the underfloor 12. The second air 602 in the underfloor 12 is sucked into the shaft 300 from the lower opening 302, flows upward through the shaft 300, and is sucked into the main body case 200. In this way, the second air 602 descends from the small roof 24 towards the underfloor 12.

[0021] As described above, since warm air rises from bottom to top, the flow of the first air 600 is suitable for heating operation of the air conditioner. Also, since cold air falls from top to bottom, the flow of the second air 602 is suitable for cooling operation of the air conditioner. The configuration and operation of the air conditioner 100 for realizing such air flows will be described below.

[0022] 2(a)-(b) show the configuration of the air conditioner 100. FIG. 2(a) is a cross-sectional view of the main body case 200 and the shaft 300 in FIG. 1. The main body case 200 and the shaft 300 in FIG. 2(a) are shown from the same direction as in FIG. 1. The main body case 200 has a box shape as described above. The main body case 200 is formed of a bottom surface 202 disposed on the lower side, a top surface 204 disposed on the upper side, and a first side surface 206a, a second side surface 206b, a third side surface 206c (not shown), and a fourth side surface 206d (not shown) connected to the bottom surface 202 and the top surface 204. The first side surface 206a to the fourth side surface 206d are collectively referred to as side surfaces 206. The bottom surface 202 and the top surface 204 face each other and are both rectangular. Each side surface 206 is also rectangular. The first side surface 206a is disposed on the shaft 300 side, and the second side surface 206b is disposed opposite the first side surface 206a. The third side surface 206c and the fourth side surface 206d face each other.

[0023] The space inside the main body case 200, that is, the space surrounded by the bottom surface 202, the top surface 204, and the multiple side surfaces 206, is the internal space 210. Although details will be described later, the first air 600 or the second air 602 from the shaft 300 is sucked into the internal space 210 through the upper part of the first side surface 206a. In the internal space 210, a filter 400 is disposed below the upper part of the first side surface 206a. The filter 400 is, for example, a HEPA (High Efficiency Particulate Air) filter. The HEPA filter is an air filter that removes dirt, dust, and the like from the first air 600 or the second air 602 sucked into the internal space 210, and outputs the purified first air 600 or the second air 602.

[0024] An air conditioner 410 is disposed below the filter 400. The air conditioner 410 is an air conditioner and controls the air conditioning of the internal space 210. The air conditioner 410 heats or cools the air that has flowed into the internal space 210 so that the temperature of the air (first air 600, second air 602) in the internal space 210 becomes a set temperature (hereinafter referred to as "set temperature"). Here, when the operation mode of the air conditioner 410 is a heating operation mode, the air conditioner 410 heats the first air 600 that has been sucked into the main body case 200. Also, when the operation mode of the air conditioner 410 is a cooling operation mode, the air conditioner 410 cools the second air 602 that has been sucked into the main body case 200. Therefore, it can be said that the first air 600 is air heated in the air conditioner 410, and the second air 602 is air cooled in the air conditioner 410. The air conditioner 410 blows out heated first air 600 or cooled second air 602, that is, conditioned air, downward.

[0025] A blower 420 is disposed below the air conditioner 410. The blower 420 blows the first air 600 or the second air 602 from the air conditioner 410 downward. The blowing of air by the blower 420 forms the flow of the first air 600 or the flow of the second air 602 in FIG. 1. The blower 420 is surrounded by a sound absorbing material 422. The sound absorbing material 422 is, for example, glass wool, and absorbs the sound generated by the rotation of the fan in the blower 420. The blower 420 is also supported from below by a vibration absorbing material 424. The vibration absorbing material 424 is, for example, rubber, and absorbs the vibration generated by the rotation of the fan in the blower 420. The sound absorbing material 422 and the vibration absorbing material 424 are also called a sound absorbing section for suppressing the generation of noise in the internal space 210.

[0026] The humidification / hypochlorous acid spraying device 430 is disposed below the blower 420. The humidification / hypochlorous acid spraying device 430 humidifies the first air 600 or the second air 602 from the air conditioner 410, or sprays hypochlorous acid to the first air 600 or the second air 602 from the air conditioner 410. A known technique may be used for the process for humidification or hypochlorous acid spraying in the humidification / hypochlorous acid spraying device 430, and therefore a description thereof will be omitted here. The first air 600 or the second air 602 humidified or sprayed with hypochlorous acid by the humidification / hypochlorous acid spraying device 430 is blown out to the shaft 300 through the lower portion of the first side surface 206a.

[0027] The air conditioner 410, the blower 420, and the humidification / hypochlorous acid spraying device 430 can communicate with the control device 500 by wireless communication or wired communication. The control device 500 controls the operation of the air conditioner 410, the blower 420, and the humidification / hypochlorous acid spraying device 430. For example, the control device 500 communicates with an air conditioning controller (not shown) outside the main body case 200, and receives information such as the operation mode, set temperature, set air volume, and the presence or absence of humidification or hypochlorous acid spraying input by the user from the air conditioning controller. Based on the received information on the operation mode, the control device 500 determines the heating operation mode or the cooling operation mode as the operation mode of the air conditioner 410, and transmits an instruction of the determined operation mode to the air conditioner 410 and transmits the set temperature to the air conditioner 410. The control device 500 also transmits the set air volume to the blower 420. Furthermore, the control device 500 transmits the presence or absence of humidification or hypochlorous acid spraying to the humidification / hypochlorous acid spraying device 430. The operation mode, the set temperature, the set air volume, the presence or absence of humidification or hypochlorous acid spraying, etc. may be automatically determined by the control device 500.

[0028] The shaft 300 is provided on the opposite side of the first side surface 206a of the main body case 200 from the internal space 210. As shown in FIG. 1, the upper end of the shaft 300 extends vertically upward from the top surface 204, and the lower end of the shaft 300 extends vertically downward from the bottom surface 202. As described above, the shaft 300 is hollow and forms one shaft air passage. In addition, a hollow space 310 extending vertically in the up-down direction is defined in a portion of the inside of the shaft 300 corresponding to the first side surface 206a. The lower end of the hollow space 310 is the hollow bottom surface 312, and the upper end of the hollow space 310 is the hollow top surface 314. The hollow bottom surface 312 is located at the same height as the bottom surface 202, and the hollow top surface 314 is located at the same height as the top surface 204.

[0029] FIG. 2(b) shows the first side surface 206a and the shaft 300 as viewed from the shaft 300 side of FIG. 2(a). The second suction port 220b and the first suction port 220a are arranged side by side in the left-right direction on the top surface 204 side of the first side surface 206a, and the first air outlet 222a and the second air outlet 222b are arranged side by side in the left-right direction on the bottom surface 202 side of the first side surface 206a. Here, the second suction port 220b and the first air outlet 222a are arranged side by side in the up-down direction, and the first suction port 220a and the second air outlet 222b are arranged side by side in the up-down direction. Each of the first suction port 220a, the second suction port 220b, the first air outlet 222a, and the second air outlet 222b is a through hole. In addition, first air inlet 220a, second air inlet 220b, first air outlet 222a, and second air outlet 222b are each provided with an openable / closable cover. The opening / closing mechanism of each cover can communicate with control device 500 in Fig. 2(a) wirelessly or by wire, and when an instruction is received from control device 500, the cover is opened or closed in accordance with the instruction.

[0030] A dividing section 320 is provided in the hollow space 310 of the shaft 300, and the dividing section 320 includes a dividing plate 322, an upper extension 324, and a lower extension 326. The dividing plate 322 extends in the vertical direction so as to penetrate between the combination of the second suction port 220b and the first blowing port 222a and the combination of the first suction port 220a and the second blowing port 222b, and is inscribed in the inner wall of the shaft 300. The upper extension 324 extends in the left-right direction from the upper end of the dividing plate 322 above the second suction port 220b, and the extending tip is inscribed in the inner wall of the shaft 300. The lower extension 326 extends in the left-right direction from the lower end of the dividing plate 322 below the second blowing port 222b, and the extending tip is inscribed in the inner wall of the shaft 300 air passage. In other words, the split portion 320 has a substantial Z-shape in side view as shown in FIG. 2(b), and can be realized by simply inserting three plates into the shaft 300, for example.

[0031] Such a dividing section 320 divides the inside of hollow space 310 into an upper air passage 330 and a lower air passage 332. Upper air passage 330 includes first suction port 220a and second air outlet 222b, is an air passage that opens to the upper side of hollow space 310, and exchanges air above main body case 200. Upper air passage 330 is connected to first suction port 220a and second air outlet 222b, and communicates hollow space 310 with internal space 210. Lower air passage 332 includes second suction port 220b and first air outlet 222a, is an air passage that opens to the lower side of hollow space 310, and exchanges air below main body case 200. Further, lower air passage 332 is connected to second air inlet 220b and first air outlet 222a, and connects hollow space 310 and internal space 210 together.

[0032] With this configuration, in order to form a flow of first air 600, first suction port 220a sucks in air carried from vertically above hollow space 310, and first outlet 222a transports the air sucked from first suction port 220a vertically downward into hollow space 310. In addition, in order to form a flow of second air 602, second suction port 220b sucks in air carried from vertically below hollow space 310, and second outlet 222b transports the air sucked from second suction port 220b vertically upward into hollow space 310.

[0033] At this time, the opening or closing of each of the first suction inlet 220a, the first outlet 222a, the second suction inlet 220b, and the second outlet 222b is controlled by the control device 500. FIG. 3 is also used to explain the control of the opening or closing by the control device 500. FIG. 3 shows the data structure of a table stored in the control device 500. For the heating operation mode, the "opening" of the first suction inlet 220a and the first outlet 222a and the "closing" of the second suction inlet 220b and the second outlet 222b are defined. For the cooling operation mode, the "closing" of the first suction inlet 220a and the first outlet 222a and the "opening" of the second suction inlet 220b and the second outlet 222b are defined. Return to FIG. 2(a)-(b).

[0034] When the control device 500 determines the heating operation mode, it refers to the table in FIG. 3 and determines whether the first air inlet 220a and the first air outlet 222a are to be "opened" and whether the second air inlet 220b and the second air outlet 222b are to be "closed." The control device 500 transmits an instruction to open the first air inlet 220a to the opening / closing mechanism. When the opening / closing mechanism of the first air inlet 220a receives the instruction to open from the control device 500, the opening / closing mechanism of the first air inlet 220a opens the first air inlet 220a by not covering the first air inlet 220a with a lid. When the control device 500 transmits an instruction to open the first air outlet 222a to the opening / closing mechanism, the first air outlet 222a is opened. When the control device 500 transmits a closing instruction to each of the opening / closing mechanisms of the second air inlet 220b and the second air outlet 222b, the second air inlet 220b and the second air outlet 222b are closed.

[0035] 4(a)-(b) show heating and cooling operations by the air conditioner 100. FIG. 4(a) shows heating operation. The first air 600 flows downward through the shaft 300 and enters the upper air passage 330. Since the first suction port 220a is open in the upper air passage 330, the first air 600 is sucked into the internal space 210 of the main body case 200 from the first suction port 220a. In the internal space 210, the first air 600 flows through the filter 400, the air conditioner 410, the blower 420, and the humidification / hypochlorous acid spraying device 430 in this order in FIG. 2(a), and is blown out from the first blowing port 222a, which is open, into the lower air passage 332. The first air 600 in the lower air passage 332 flows downward through the shaft 300. This forms the flow of the first air 600 in FIG. 1. Figure 4(b) will be discussed later, and we return to Figures 2(a)-(b).

[0036] When the control device 500 determines the cooling operation mode, it refers to the table in Fig. 3 and determines whether the first air inlet 220a and the first air outlet 222a are "closed" and whether the second air inlet 220b and the second air outlet 222b are "opened." The control device 500 transmits a command to close the first air inlet 220a to the opening / closing mechanism. When the opening / closing mechanism of the first air inlet 220a receives the command to close from the control device 500, it closes the first air inlet 220a by covering the first air inlet 220a with a lid. When the control device 500 transmits a command to close the first air outlet 222a to the opening / closing mechanism of the first air outlet 222a, the first air outlet 222a is closed. When the control device 500 transmits an instruction to open to the opening / closing mechanisms of the second air inlet 220b and the second air outlet 222b, the second air inlet 220b and the second air outlet 222b are opened.

[0037] FIG. 4(b) shows cooling operation. The second air 602 flows from the bottom to the top of the shaft 300 and enters the lower air passage 332. Since the second suction port 220b is open in the lower air passage 332, the second air 602 is sucked into the internal space 210 of the main body case 200 from the second suction port 220b. In the internal space 210, the second air 602 flows through the filter 400, the air conditioner 410, the blower 420, and the humidification / hypochlorous acid spraying device 430 in this order in FIG. 2(a), and is blown out from the open second blowing port 222b to the upper air passage 330. The second air 602 in the upper air passage 330 flows from the bottom to the top of the shaft 300. This forms the flow of the second air 602 in FIG. 1.

[0038] The air conditioner 100 described above is installed in a two-story house 10 as shown in Fig. 1. However, the house in which the air conditioner 100 is installed may be a house other than two stories. Fig. 5 shows the configuration of a house 30 according to a modified example. The house 30 is a single-story building, and includes an underfloor space 12, a floor surface 14, a first-floor room 16, a ceiling surface 22, and a small roof 24. In the house 30, the underfloor space 12, the first-floor room 16, and the small roof 24 are arranged in this order from bottom to top. In addition, the underfloor space 12 and the first-floor room 16 are separated by the floor surface 14, and the first-floor room 16 and the small roof 24 are separated by the ceiling surface 22.

[0039] A box-shaped main body case 200 is installed in a first floor room 16 of a house 30. The main body case 200 and the shaft 300 are configured in the same manner as before. Therefore, when the air conditioner 100 is in heating operation, a flow of first air 600 is formed, and when the air conditioner 100 is in cooling operation, a flow of second air 602 is formed.
