Abstract

There is a demand to simplify a structure for switching between air supply and air discharge. This ventilation device comprises a ventilation fan, a jetting switching mechanism (33), a first switching mechanism (34), and a control unit. The jetting switching mechanism (33) is capable of switching between a first state in which a ventilation hose is allowed to communicate with the ventilation fan (32) but a second opening is not allowed to communicate with the ventilation fan (32), and a second state in which the second opening is allowed to communicate with the ventilation fan (32) but the ventilation hose is not allowed to communicate with the ventilation fan (32). The first switching mechanism (34) is capable of switching between a third state in which a third opening (31c) for allowing communication between a flow-through space and the ventilation hose in a manner that bypasses the ventilation fan (32) allows communication between the flow-through space and the ventilation hose, and a fourth state in which the third opening does not allow communication between the flow-through space and the ventilation hose. The control unit sets the jetting switching mechanism (33) in the first state and sets the first switching mechanism (34) in the fourth state to carry out an air supply operation. The control unit sets the jetting switching mechanism (33) in the second state and sets the first switching mechanism (34) in the third state to carry out an air discharge operation.

The ventilation fan draws air from the ventilation space through a suction opening formed in the support base, and blows the air toward the first opening or the second opening. The blowout switching mechanism is capable of switching between a first state and a second state. The first state is a state in which the blower fan and the ventilation hose are in communication with each other, and the blower fan and the second opening are not in communication with each other. The second state is a state in which the blower fan and the second opening are in communication with each other, and the blower fan and the ventilation hose are not in communication with each other. The first switching mechanism is capable of switching between a third state and a fourth state. The third state is a state in which the third opening for communicating the ventilation space and the ventilation hose without using the ventilation fan causes the ventilation space and the ventilation hose to communicate with each other. The fourth state is a state in which the third opening does not allow communication between the ventilation space and the ventilation hose. The control unit performs air supply operation. The air supply operation is an operation that supplies air into the room. The control unit performs air supply operation by setting the blow-off switching mechanism to the first state, setting the first switching mechanism to the fourth state, and driving the blower fan. The control unit performs exhaust operation. The exhaust operation is an operation that exhausts air from the room. The control unit performs exhaust operation by driving the blower fan with the blow-off switching mechanism in the second state and the first switching mechanism in the third state.
　第１観点の換気装置では、給気運転は、吹出切換機構を第１状態とし、第１切換機構を第４状態として、送風ファンを駆動することにより、室内に空気を供給する運転である。排気運転は、吹出切換機構を第２状態とし、第１切換機構を第３状態として、送風ファンを駆動することにより、室内から空気を排出する運転である。その結果、換気装置は、より簡素な構造により、給気と排気を切り換えることができる。 In the ventilation system of the first aspect, the air supply operation is an operation in which air is supplied into the room by setting the blow-off switching mechanism to the first state, setting the first switching mechanism to the fourth state, and driving the ventilation fan. The exhaust operation is an operation in which air is discharged from the room by setting the blow-off switching mechanism to the second state, setting the first switching mechanism to the third state, and driving the blower fan. As a result, the ventilation device can switch between supply and exhaust air with a simpler structure.
　第２観点の換気装置は、第１観点の換気装置であって、加湿ロータをさらに備える。加湿ロータは、空気中の水分を吸着する。ケーシングには、さらに第４開口が形成されている。第４開口は、室外に連通する。制御部は、加湿運転を行う。加湿運転は、第４開口から加湿ロータを介して通風空間に取り入れた加湿空気を、室内に供給する運転である。制御部は、吹出切換機構を第１状態とし、第１切換機構を第４状態として、送風ファンを駆動することにより、加湿運転を行う。 The ventilation device according to the second aspect is the ventilation device according to the first aspect, and further includes a humidification rotor. The humidifying rotor adsorbs moisture in the air. A fourth opening is further formed in the casing. The fourth opening communicates with the outside. The control unit performs humidification operation. The humidification operation is an operation in which humidified air taken into the ventilation space from the fourth opening via the humidification rotor is supplied into the room. The control unit performs humidification operation by setting the blow-off switching mechanism to the first state, setting the first switching mechanism to the fourth state, and driving the blower fan.
　第３観点の換気装置は、第２観点の換気装置であって、第２切換機構をさらに備える。第２切換機構は、第５状態と、第６状態と、を切り換え可能である。第５状態は、加湿ロータと送風ファンとを連通させる状態である。第６状態は、加湿ロータと送風ファンとを連通させない状態である。制御部は、第２切換機構を第５状態として、給気運転および加湿運転を行う。制御部は、第２切換機構を第６状態として、排気運転を行う。 The ventilation device according to the third aspect is the ventilation device according to the second aspect, and further includes a second switching mechanism. The second switching mechanism is capable of switching between a fifth state and a sixth state. The fifth state is a state in which the humidifying rotor and the ventilation fan are communicated with each other.

The control unit sets the second switching mechanism to the fifth state and performs air supply operation and humidification operation. The control unit sets the second switching mechanism to the sixth state and performs the exhaust operation.
　第３観点の換気装置では、制御部は、第２切換機構を第６状態として、排気運転を行う。第６状態は、加湿ロータと送風ファンとを連通させない状態である。その結果、換気装置は、送風ファンが加湿ロータ側から空気を吸い込まないため、より効果的に室内の空気を吸い込む（室内から排気する）ことができる。 In the ventilation system according to the third aspect, the control unit sets the second switching mechanism to the sixth state and performs the exhaust operation. The sixth state is a state in which the humidifying rotor and the blower fan are not communicated with each other. As a result, since the ventilation fan does not suck in air from the humidifying rotor side, the ventilation device can more effectively suck in indoor air (exhaust air from the indoor room).
　第４観点の換気装置は、第１観点から第３観点のいずれかの換気装置であって、制御部は、再生運転を行う。再生運転は、加湿ロータに吸着した水分を放出させる運転である。制御部は、吹出切換機構を第２状態とし、第１切換機構を第４状態として、再生運転を行う。 The ventilation device according to the fourth aspect is any one of the ventilation devices according to the first to third aspects, and the control unit performs a regeneration operation. The regeneration operation is an operation in which moisture adsorbed by the humidification rotor is released. The control unit performs regeneration operation with the blow-off switching mechanism in the second state and the first switching mechanism in the fourth state.
　第４観点の換気装置は、このような構成により、第２開口を、排気運転と再生運転の両方に用いることができる。 With such a configuration, the ventilation device according to the fourth aspect can use the second opening for both exhaust operation and regeneration operation.
　第５観点の換気装置は、第３観点の換気装置であって、制御部は、第１切換機構の状態の切り換えに連動して、吹出切換機構および第２切換機構の状態を切り換える。または、制御部は、第２切換機構の状態の切り換えに連動して、吹出切換機構および第１切換機構の状態を切り換える。 The ventilation device according to the fifth aspect is the ventilation device according to the third aspect, in which the control unit switches the states of the blow-off switching mechanism and the second switching mechanism in conjunction with switching the state of the first switching mechanism. Alternatively, the control unit switches the states of the blow-off switching mechanism and the first switching mechanism in conjunction with switching the state of the second switching mechanism.
　第５観点の換気装置は、このような構成により、切換機構の制御を、単純化することができる。 With such a configuration, the ventilation device according to the fifth aspect can simplify control of the switching mechanism.

　図３に示すように、加湿ロータ３６は、円盤状の部材である。加湿ロータ３６には、例えば、ゼオライト、シリカゲル、およびアルミナ等が用いられる。ヒータ３７によって加熱されていない室外ＯＴの空気が、加湿ロータ３６を通過するとき、加湿ロータ３６は空気中の水分を吸着する（水分を吸着された空気は、乾燥空気となる）。一方、ヒータ３７によって加熱された室外ＯＴの空気が、水分を吸着した加湿ロータ３６を通過するとき、加湿ロータ３６から水分が放出され、加熱された空気に水分が供給される（水分が供給された空気は、加湿空気となる）。加湿ロータ３６は、加湿ロータモータ３６ｍによって、回転軸３６ｃを中心に回転する。加湿ロータモータ３６ｍの回転数は、インバータにより制御可能である。 (2-3-6) Humidifying Rotor As shown in FIG. 3, the humidifying rotor 36 is a disc-shaped member. The humidifying rotor 36 is made of, for example, zeolite, silica gel, alumina, or the like. When outdoor OT air that has not been heated by the heater 37 passes through the humidifying rotor 36, the humidifying rotor 36 adsorbs moisture in the air (the air that has absorbed moisture becomes dry air). On the other hand, when outdoor OT air heated by the heater 37 passes through the humidifying rotor 36 that has adsorbed moisture, moisture is released from the humidifying rotor 36 and moisture is supplied to the heated air (moisture is not supplied). air becomes humidified air).

The outdoor OT air sucked in through the fourth opening 31d and the fifth opening 31e passes through the heater 37 and then the humidification rotor 36. When the outdoor OT air heated by the heater 37 passes through the humidifying rotor 36 that has adsorbed moisture, the passed air becomes humidified air. The heater 37 can change the output, and the temperature of the air passing through the heater 37 can be changed depending on the output. Within a specific temperature range, the higher the temperature of the air passing through the humidifying rotor 36, the greater the amount of moisture desorbed from the humidifying rotor 36.

The sucked air passes through the left half disk portion of the humidifying rotor 36 and flows above the humidifying rotor 36. At this time, the humidifying rotor 36 adsorbs moisture in the air. The air flowing above the humidifying rotor 36 flows above the suction fan 38. The air flowing above the suction fan 38 is sucked by the suction fan 38 through the suction opening 52a.

　本実施形態の換気装置３０では、給気運転は、吹出切換機構３３を第１状態とし、第１切換機構３４を第４状態として、換気ファン３２を駆動することにより、室内ＲＭに空気を供給する運転である。排気運転は、吹出切換機構３３を第２状態とし、第１切換機構３４を第３状態として、換気ファン３２を駆動することにより、室内ＲＭから空気を排出する運転である。その結果、換気装置３０は、より簡素な構造により、給気と排気を切り換えることができる。 In the ventilation device 30 of this embodiment, air supply operation is performed by setting the blow-off switching mechanism 33 in the first state, setting the first switching mechanism 34 in the fourth state, and driving the ventilation fan 32 to supply air to the indoor RM. This is a driving style. The exhaust operation is an operation in which air is discharged from the indoor RM by setting the blow-off switching mechanism 33 to the second state, setting the first switching mechanism 34 to the third state, and driving the ventilation fan 32. As a result, the ventilation device 30 can switch between supply and exhaust air with a simpler structure.
　（３－２）
　本実施形態の換気装置３０は、加湿ロータ３６をさらに備える。加湿ロータ３６は、空気中の水分を吸着する。ケーシング３１には、さらに第４開口３１ｄが形成されている。第４開口３１ｄは、室外ＯＴに連通する。制御部６０は、加湿運転を行う。加湿運転は、第４開口３１ｄから加湿ロータ３６を介して通風空間ＳＰ２に取り入れた加湿空気を、室内ＲＭに供給する運転である。制御部６０は、吹出切換機構３３を第１状態とし、第１切換機構３４を第４状態として、換気ファン３２を駆動することにより、加湿運転を行う。 (3-2)
The ventilation device 30 of this embodiment further includes a humidification rotor 36. The humidifying rotor 36 adsorbs moisture in the air. The casing 31 further has a fourth opening 31d formed therein. The fourth opening 31d communicates with the outdoor OT. The control unit 60 performs humidification operation. The humidification operation is an operation in which humidified air taken into the ventilation space SP2 from the fourth opening 31d via the humidification rotor 36 is supplied to the indoor room RM. The control unit 60 performs humidification operation by driving the ventilation fan 32 with the blowout switching mechanism 33 in the first state and the first switching mechanism 34 in the fourth state.
　（３－３）
　本実施形態の換気装置３０は、第２切換機構３５をさらに備える。第２切換機構３５は、第５状態と、第６状態と、を切り換え可能である。第５状態は、加湿ロータ３６と換気ファン３２とを連通させる状態である。第６状態は、加湿ロータ３６と換気ファン３２とを連通させない状態である。制御部６０は、第２切換機構３５を第５状態として、給気運転および加湿運転を行う。制御部６０は、第２切換機構３５を第６状態として、排気運転を行う。 (3-3)
The ventilation device 30 of this embodiment further includes a second switching mechanism 35. The second switching mechanism 35 is capable of switching between a fifth state and a sixth state. The fifth state is a state in which the humidifying rotor 36 and the ventilation fan 32 are communicated with each other. The sixth state is a state in which the humidifying rotor 36 and the ventilation fan 32 are not communicated with each other. The control unit 60 sets the second switching mechanism 35 to the fifth state and performs the air supply operation and the humidification operation. The control unit 60 sets the second switching mechanism 35 to the sixth state and performs the exhaust operation.
　本実施形態の換気装置３０では、制御部６０は、第２切換機構３５を第６状態として、排気運転を行う。第６状態は、加湿ロータ３６と換気ファン３２とを連通させない状態である。その結果、換気装置３０は、換気ファン３２が加湿ロータ３６側から空気を吸い込まないため、より効果的に室内ＲＭの空気を吸い込む（室内ＲＭから排気する）ことができる。 In the ventilation device 30 of this embodiment, the control unit 60 sets the second switching mechanism 35 to the sixth state and performs the exhaust operation. The sixth state is a state in which the humidifying rotor 36 and the ventilation fan 32 are not communicated with each other. As a result, since the ventilation fan 32 does not suck in air from the humidifying rotor 36 side, the ventilation device 30 can more effectively suck in air from the indoor RM (exhaust air from the indoor RM).
　（３－４）
　本実施形態の換気装置３０では、制御部６０は、再生運転を行う。再生運転は、加湿ロータ３６に吸着した水分を放出させる運転である。制御部６０は、吹出切換機構３３を第２状態とし、第１切換機構３４を第４状態として、再生運転を行う。 (3-4)
In the ventilation device 30 of this embodiment, the control unit 60 performs a regeneration operation. The regeneration operation is an operation in which moisture adsorbed by the humidifying rotor 36 is released. The control unit 60 performs regeneration operation with the blow-off switching mechanism 33 in the second state and the first switching mechanism 34 in the fourth state.
　その結果、換気装置３０は、第２開口３１ｂを、排気運転と再生運転の両方に用いることができる。 As a result, the ventilation device 30 can use the second opening 31b for both exhaust operation and regeneration operation.
　（４）変形例
　（４－１）変形例１Ａ
　制御部６０は、第１切換機構３４の状態の切り換えに連動して、吹出切換機構３３および第２切換機構３５の状態を切り換えてもよい。また、制御部６０は、第２切換機構３５の状態の切り換えに連動して、吹出切換機構３３および第１切換機構３４の状態を切り換えてもよい。 (4) Modification (4-1) Modification 1A
The control unit 60 may switch the states of the blow-off switching mechanism 33 and the second switching mechanism 35 in conjunction with switching the state of the first switching mechanism 34 . Further, the control unit 60 may switch the states of the blow-off switching mechanism 33 and the first switching mechanism 34 in conjunction with switching the state of the second switching mechanism 35.
　その結果、換気装置３０は、切換機構の制御を、単純化することができる。 As a result, the ventilation device 30 can simplify the control of the switching mechanism.
　（４－２）変形例１Ｂ
　本実施形態では、室外機２０と、換気装置３０とは、一体化されていた。しかし、室外機２０と、換気装置３０とは、別体であってもよい。このとき、換気装置３０は、例えば、室外機２０の横に設置される。 (4-2) Modification 1B
In this embodiment, the outdoor unit 20 and the ventilation device 30 are integrated. However, the outdoor unit 20 and the ventilation device 30 may be separate bodies. At this time, the ventilation device 30 is installed next to the outdoor unit 20, for example.
　（４－３）変形例１Ｃ
　本実施形態では、吹出切換機構３３は、回転軸３３ｂを中心に切換部材３３ａを回転させることにより、第１状態と、第２状態と、を切り換えた。しかし、これに限定されず、第１状態と、第２状態と、を切り換えることができれば、吹出切換機構３３の切換構造は任意である。 (4-3) Modification example 1C
In this embodiment, the blowout switching mechanism 33 switches between the first state and the second state by rotating the switching member 33a around the rotating shaft 33b. However, the present invention is not limited to this, and the switching structure of the blowout switching mechanism 33 is arbitrary as long as it can switch between the first state and the second state.
　本実施形態では、第１切換機構３４は、回転軸３４ｂを中心に切換部材３４ａを回転させることにより、第３状態と、第４状態と、を切り換えた。しかし、これに限定されず、第３状態と、第４状態と、を切り換えることができれば、第１切換機構３４の切換構造は任意である。 In the present embodiment, the first switching mechanism 34 switches between the third state and the fourth state by rotating the switching member 34a around the rotating shaft 34b. However, the present invention is not limited to this, and the switching structure of the first switching mechanism 34 is arbitrary as long as it can switch between the third state and the fourth state.
　本実施形態では、第２切換機構３５は、切換部材３５ａを上下にスライドさせることにより、第５状態と、第６状態と、を切り換えた。しかし、これに限定されず、第５状態と、第６状態と、を切り換えることができれば、第２切換機構３５の切換構造は任意である。 In the present embodiment, the second switching mechanism 35 switches between the fifth state and the sixth state by sliding the switching member 35a up and down. However, the present invention is not limited to this, and the switching structure of the second switching mechanism 35 is arbitrary as long as it can switch between the fifth state and the sixth state.
　（４－４）変形例１Ｄ
　本実施形態では、支持台５０には、開口５０ｂと、吹出切換機構３３が第２状態である場合の切換部材３３ａと、の間に、第３開口３１ｃが形成されていた。しかし、第３開口３１ｃは、ケーシング３１の側面であって、通風空間ＳＰ２と直接連通する箇所に形成されてもよい。図１４は、本変形例における第３開口３１ｃ’の位置を示す図である。図１４では、第３開口３１ｃ’は、ケーシング３１の右方側面であって、第５開口３１ｅを構成する孔の下方に形成されている。第３開口３１ｃ’は、通風空間ＳＰ２と直接連通する箇所に形成されている。図１４では、換気ホース７０の換気装置３０側の端を２つに分岐させることにより、換気ホース７０を第１開口３１ａと第３開口３１ｃ’に連通させている。 (4-4) Modification example 1D
In this embodiment, the third opening 31c is formed in the support base 50 between the opening 50b and the switching member 33a when the blowout switching mechanism 33 is in the second state. However, the third opening 31c may be formed in a side surface of the casing 31 at a location that directly communicates with the ventilation space SP2. FIG. 14 is a diagram showing the position of the third opening 31c' in this modification. In FIG. 14, the third opening 31c' is formed on the right side surface of the casing 31 below the hole that constitutes the fifth opening 31e. The third opening 31c' is formed at a location that directly communicates with the ventilation space SP2. In FIG. 14, the ventilation hose 70 is made to communicate with the first opening 31a and the third opening 31c' by branching the end of the ventilation hose 70 on the side of the ventilation device 30 into two parts.
　このとき、第１切換機構３４’の切換部材３４ａ’は、例えば、ケーシング３１内の右方側面に設置される。切換部材３４ａ’は、モータによって前後にスライドする。第１切換機構３４’は、切換部材３４ａ’を前後にスライドさせることにより、第３開口３１ｃ’を開閉することができる。言い換えると、第１切換機構３４’は、切換部材３４ａ’を前後にスライドさせることにより、第３状態と、第４状態と、を切り換え可能である。 At this time, the switching member 34a' of the first switching mechanism 34' is installed, for example, on the right side surface inside the casing 31. The switching member 34a' is slid back and forth by a motor. The first switching mechanism 34' can open and close the third opening 31c' by sliding the switching member 34a' back and forth. In other words, the first switching mechanism 34' can switch between the third state and the fourth state by sliding the switching member 34a' back and forth.
　例えば、制御部６０が排気運転を行う場合、換気ファン３２が駆動すると、第１切換機構３４’が第３状態であるため、室内ＲＭの空気は、換気ホース７０を通じて、第１開口３１ａと第３開口３１ｃ’に吸い込まれる。第１開口３１ａに吸い込まれた空気は、吹出切換機構３３が第２状態であるため、遮断される。第３開口３１ｃ’に吸い込まれた空気は、直接、通風空間ＳＰ２に流入する。言い換えると、第３開口３１ｃ’は、換気ファン３２を介さずに通風空間ＳＰ２と換気ホース７０とを連通させるための孔である。 For example, when the control unit 60 performs exhaust operation, when the ventilation fan 32 is driven, the first switching mechanism 34' is in the third state, so the air in the room RM flows through the ventilation hose 70 to the first opening 31a and the first opening 31a. 3 opening 31c'. The air sucked into the first opening 31a is blocked because the blowout switching mechanism 33 is in the second state. The air sucked into the third opening 31c' directly flows into the ventilation space SP2. In other words, the third opening 31c' is a hole for communicating the ventilation space SP2 and the ventilation hose 70 without using the ventilation fan 32.
