Description

[Technical field]

[0001] The present invention relates to a blower installed in a residence such as a detached house or an apartment building, and a residential air conditioning system equipped with the blower. [Background technology]

[0002] In recent years, air conditioners are used in many houses, and in some houses, indoor units constituting the air conditioner are installed in each of the main rooms such as the living room and bedroom, and outdoor units corresponding to each indoor unit are installed outside. On the other hand, in order to increase the thermal efficiency of such air conditioners and reduce the burden of energy costs, houses with high airtightness and high insulation performance are also becoming popular. However, as mentioned above, when installing multiple air conditioners in a house, not only the multiple indoor units but also the corresponding outdoor units must be installed outdoors, which increases the initial cost, and in consideration of the housing situation in small areas such as urban areas, it is not uncommon to be unable to install multiple outdoor units. In addition, when the neighboring house is close to the outdoor unit, the outdoor unit cannot secure sufficient air inflow space due to the fence or wall constructed on the boundary with the neighboring land, and further, the driving sound of the multiple outdoor units may become noise and develop into trouble with the neighboring house.

[0003] In order to solve these problems, a technology has been developed that can handle multiple indoor units with one outdoor unit. For example, the technology disclosed in JP-A-7-190415 (Patent Document 1) is a multi-configuration in which indoor units of an air-conveying air conditioner are installed on each floor of a house or in each zoning area, and one outdoor unit is used. This technology also has a configuration in which air is discharged through an outlet into each room via a duct, and air is sucked in by the indoor unit body, allowing air conditioning for the entire building. This technology can reduce the number of outdoor units used up to now to just one, and if we focus only on this point, it can be evaluated as contributing to cost reduction.

[0004] Also, conventionally, an air conditioning system has been proposed as disclosed in JP 2021-148382 A (Patent Document 2). This air conditioning system conveys air discharged from an indoor unit installed in a first zone such as a hallway to a second zone such as a living room via a blower without using a duct as in Patent Document 1 described above. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 7-190415 [Patent Document 2] JP 2021-148382 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, even with the technology disclosed in the above Patent Document 1, the number of indoor units installed in a house remains multiple, and not only is it not possible to reduce costs to that extent, but the distance between the single outdoor unit and the multiple indoor units increases, which results in an increase in the length of the refrigerant pipes, and when considering the overall installation cost including the labor and costs involved in installation, it does not contribute much to cost reduction compared to installing multiple outdoor units corresponding to multiple indoor units. Furthermore, since this technology is based on a basic structure in which one outdoor unit serves multiple indoor units, the capacity and burden required of the outdoor unit are large, and the outdoor unit has to operate at full capacity, which inevitably results in a high noise level.

[0007] Recently, a whole-house air-conditioning system has been proposed in which a single air conditioner consisting of one outdoor unit and one indoor unit is installed. However, this whole-house air-conditioning system also has various problems, which will be described below, and lacks appropriateness. First, this system uses one indoor unit to provide heating and cooling for the entire house, and therefore requires the installation of ducts to move the air discharged from the indoor unit to multiple rooms. The more rooms to be cooled or heated, the more ducts there are, and the farther the rooms to be cooled or heated are from the outdoor unit, the longer the ducts are, which inevitably results in higher construction costs. In addition, in order to move and transport heat from the indoor unit to each room using air with a low specific heat, a large air volume is required, and as a result, the diameter of the duct must be large. Considering that there is no space for piping such a large-diameter duct other than above the ceiling, construction costs required to lower the overall or partial ceiling height are also unavoidable. Furthermore, even if the duct used is large in diameter, multiple ducts are installed, and the driving noise of the fan that constitutes the outdoor unit becomes loud, greatly hindering the realization of a comfortable living space.

[0008] In addition, the air conditioning system disclosed in the above Patent Document 2 transports air from the indoor unit installed in the first zone to the second zone by the blower as described above, but the first zone is provided with an outdoor air intake port that meets the required ventilation air volume of the target floor and an indoor exhaust port that exhausts air equivalent to the intake air volume to the outdoors, and specifically, a heat exchange type ventilator that uses a heat exchange element to recover heat and humidity from the outdoor air intake through the outdoor air intake port and the indoor exhaust air through the indoor exhaust port to ventilate while saving energy, and the heat exchange type ventilator is installed in the attic above the ceiling. However, since the outdoor air supply port and the indoor exhaust port are formed in the same first zone, the outdoor air and the exhaust air mix with each other, and it is not possible to avoid the occurrence of insufficient ventilation and energy loss. In addition, Patent Document 2 discloses an example of providing a chamber space in the ceiling as a means to avoid the above energy loss, and a structure in which an exhaust chamber space is provided in the ceiling space, and the exhaust air passes through the exhaust chamber space and is sent to the heat exchange type ventilator and exhausted to the outdoors. However, with this type of structure, depending on the location (floor plan) of the second zone to which air is transported from within the first zone, the entire area above the ceiling of the first zone may become the chamber space or exhaust chamber space, which not only significantly lowers the ceiling height and creates a feeling of oppression in the entire living space (living space), but also requires much effort and costs in construction.

[0009] Therefore, the present invention has been proposed to solve the various problems associated with conventional residential air conditioning systems as described above, and aims to provide a residential air conditioning system and a blower for use in said system which not only reduces the number of indoor units and outdoor units that make up the air conditioner, but also does not require the use of ducts as a means of moving air from the indoor units to each room, and further reduces the effort required for construction by not lowering the ceiling height of spaces such as corridors where the indoor units are located, thereby significantly reducing the introduction costs, including construction expenses. [Means for solving the problem]

[0010] In order to achieve the above-mentioned object, the first invention (the invention described in claim 1) relates to a blower which is installed in a specific space such as a hallway or dining room constituting a residence, and blows air discharged from an indoor unit constituting an air conditioner, to a room adjacent to the specific space and having an exhaust port for exhausting the air inside, the blower being characterized in that it is installed in a partition wall separating the specific space from the adjacent room, and has a fan which blows air from the specific space in the direction of the adjacent room.

[0011] The blower according to the first invention is installed in a specific space such as a hallway or dining room constituting a house, and blows air discharged from an indoor unit constituting an air conditioner to a room adjacent to the specific space, and is installed on a partition wall separating the specific space from the adjacent room. The specific space may be any space in which the indoor unit is installed, and may include various spaces depending on the layout of the house, such as the hallway or dining room listed as examples, the entrance hall, living room, etc. For example, if there is no hallway and the living / dining room is adjacent to the entrance hall and occupies a large area, the living / dining room is preferably the specific space. In addition, if the house is two stories high, it is preferable to install the indoor unit in a hall that is connected to the staircase space leading from the first floor to the second floor as the specific space. On the other hand, the adjacent rooms constituting the first invention are rooms as spaces adjacent to the specific room, and when the corridor is the specific space in which the indoor unit is installed, if a living / dining room, study, bedroom, Japanese-style room, dressing room, or walk-in closet is adjacent to the corridor, these rooms correspond to the adjacent rooms. Also, when the above-mentioned corridor does not exist and the living / dining room, which is the specific space, is directly adjacent to the entrance hall, and the living / dining room is adjacent to the study, bedroom, Japanese-style room, dressing room, etc., the study, bedroom, Japanese-style room, dressing room, etc. correspond to the adjacent rooms. Also, in a two-story house, when the hall is the specific space, if the hall is adjacent to the study, bedroom, Japanese-style room, walk-in closet, etc., the study, bedroom, Japanese-style room, dressing room, etc. correspond to the adjacent rooms. In addition, an exhaust port for discharging the air inside is provided in the adjacent rooms. This exhaust port may be provided on the ceiling or side wall of the adjacent rooms.

[0012] Therefore, with the blower of the first aspect of the invention, there is no need to install indoor units in each room and corresponding outdoor units outside the house, which allows for a significant reduction in the number of air conditioners to be installed throughout the house, and there is no need for ducts as a means of transporting hot and cold air discharged from the indoor units directly to the adjacent rooms. As a result, the introduction costs, including the construction costs for piping the ducts, can be significantly reduced, and noise generation can be sufficiently suppressed, as well as there is no need to lower the ceiling height, which greatly contributes to the realization of a comfortable living space.

[0013] The second invention (the invention described in claim 2) relates to the same blower as the first invention, and is a blower that is installed in a specific space such as a hallway or dining room that constitutes a house, and blows air discharged from an indoor unit that constitutes an air conditioner into an adjacent room that is able to communicate with the specific space via an entrance and exit and in which an exhaust port for exhausting the air inside is disposed, wherein the blower is disposed in a partition wall that is formed above an entrance fitting such as a door or sliding door attached to the entrance and that separates the specific space from the adjacent room, and has a fan that blows air from the specific space in the direction of the adjacent room.

[0014] In comparison, the blower according to the first invention is arranged on a partition wall separating the specific space from the adjacent room in the first invention, whereas the blower according to the second invention is arranged on a partition wall formed above an entrance fitting such as a door or sliding door attached to the entrance and separating the specific space from the adjacent room in the second invention. Even with the blower according to the second invention, the same effects as those of the blower according to the first invention can be achieved.

[0015] Furthermore, the blower of the second invention is not limited in any way in shape, size, number of fans, or location, so long as it is placed on the partition wall formed at least above the entrance / exit fitting and blows air from within the specific space to the adjacent room.

[0016] Furthermore, the third invention (the invention described in claim 3) relates to a residential air conditioning system, and is installed in a house having a specific space such as a hallway or dining room, and an adjacent room via a partition wall formed between the specific space and the room, the room having an exhaust port for exhausting the air inside, wherein an indoor unit constituting an air conditioner is installed in the specific space, and a blower equipped with a fan for blowing the air within the specific space to the adjacent room is installed in the partition wall, and the air discharged from the indoor unit into the specific space is blown into the adjacent room by driving the fan, and the air within the adjacent room is exhausted to the outside of the house through the exhaust port.

[0017] The residential air conditioning system according to the third aspect of the present invention is a residential air conditioning system equipped with the blower according to the first aspect of the present invention, and has the same effects as the blower according to the first aspect of the present invention.

[0018] The fourth invention (the invention described in claim 4) relates to the same residential air conditioning system as the third invention, and is a residential air conditioning system installed in a house having a specific space such as a hallway or dining room, an adjacent room via a partition wall formed between the specific space and the adjacent room, the room having an exhaust port for exhausting the air inside, an entrance formed in the partition wall to allow communication between the specific space and the adjacent room, and an entrance fitting such as a door or a sliding door attached to the entrance, wherein an indoor unit constituting an air conditioner is installed in the specific space, and a blower equipped with a fan for blowing air from the specific space to the adjacent room is arranged above the partition wall and the entrance fitting, and the air discharged from the indoor unit into the specific space is blown into the adjacent room by driving the fan, and the air from the adjacent room is exhausted to the outside of the house through the exhaust port.

[0019] The residential air conditioning system according to the fourth aspect of the present invention is a residential air conditioning system equipped with the blower according to the second aspect of the present invention, and has the same effects as the blower according to the second aspect of the present invention described above.

[0020] The fifth invention (the invention described in claim 5) is characterized in that, in either the third or fourth invention, next to the adjacent room, another adjacent room having an exhaust port for exhausting the air inside is provided via another partition wall having another entrance / exit formed therein, allowing communication between the adjacent room and the other adjacent room, and another entrance / exit fitting such as a door or sliding door is attached to the other entrance / exit, and another fan is arranged on the other partition wall above the other entrance / exit fitting.

[0021] In the residential air conditioning system according to the fifth aspect of the invention, another adjacent room is formed to the adjacent room, another partition wall is formed between the adjacent room and the other adjacent room, and another entranceway is formed in the other partition wall to allow communication between the adjacent rooms. Then, another entranceway fixture such as a door or a sliding door is attached to the other entranceway, and another fan is disposed in the other partition wall above the other entranceway fixture.

[0022] Therefore, according to the residential air conditioning system of the fifth aspect of the invention, the air discharged from the indoor unit into the specific space is blown from the specific room to the adjacent room by driving the fan that constitutes the blower, and the air in the adjacent room is also blown to the other adjacent room by the other blower, making it possible to achieve air conditioning by the indoor unit over an even wider area.

[0023] Further, a sixth invention (invention described in claim 6) is any one of the third, fourth or fifth inventions, wherein a residential ventilation device is disposed within the house, and the residential ventilation device includes an outside air inlet duct for introducing outside air into the house, an outside air supply duct for supplying the outside air that has flowed in from the outside air inlet duct into the specific space, an indoor air suction duct for sucking in air within the adjacent room or the other adjacent room, an indoor air exhaust duct for exhausting the indoor air that has flowed into the indoor air exhaust duct to the outside of the house, a heat exchange element for exchanging heat between air from the outside air inlet duct to the outside air supply duct and air from the indoor air suction duct to the indoor air exhaust duct, and a heat exchange element that is driven so that the air that has flowed in from the outside air inlet duct reaches the outside air supply duct. and a second ventilation fan which is driven to guide air flowing in from the indoor air suction duct to the indoor air exhaust duct, an air intake port which is connected to the outdoor air supply duct is formed in a ceiling formed in the specific space, and the outdoor air is supplied into the specific space through the air intake port which is connected to the outdoor air inflow duct and the outdoor air supply duct by driving the first ventilation fan, and air discharged from an indoor unit installed in the specific space is blown into the adjacent room through the blower, and the air in the adjacent room or the other adjacent room is discharged to the outside of the house through the indoor air suction duct which is connected to the exhaust port and the indoor air exhaust duct by driving the second ventilation fan.

[0024] The residential air conditioning system according to the sixth aspect of the present invention utilizes (as a component) a residential ventilation device arranged in a house. The residential ventilation device includes an outside air inlet duct for introducing outside air into the house, an outside air supply duct for supplying the outside air introduced from the outside air inlet duct into the specific space, an indoor air suction duct for sucking in air in the adjacent room or the other adjacent room, an indoor air exhaust duct for exhausting the indoor air introduced into the indoor air suction duct to the outside of the house, a heat exchange element for exchanging heat between the air from the outside air inlet duct to the outside air supply duct and the air from the indoor air suction duct to the indoor air exhaust duct, a first ventilation fan for driving the air introduced from the outside air inlet duct to the outside air supply duct, and a second ventilation fan for driving the air introduced from the indoor air suction duct to the indoor air exhaust duct. When the first and second ventilation fans constituting the residential ventilation device are driven, the outside air is supplied into the specific space through the air supply port communicating with the outside air inlet duct and the outside air supply duct by the driving of the first ventilation fan. The air discharged from the indoor unit installed in the specific space is blown into the adjacent room through the blower, and the air in the adjacent room or the other adjacent room is discharged outside the house through the indoor air suction duct and the indoor air exhaust duct communicating with the exhaust port by the driving of the second ventilation fan. That is, in the residential air conditioning system according to the sixth invention, when the blower blows air from the specific space to the adjacent room or other adjacent rooms, the adjacent room or other adjacent rooms are brought into negative pressure by the driving of the second ventilation fan. The residential ventilation device may be arranged in a space other than the ceiling, for example, in a closet or a space formed next to a closet, or a space formed next to a toilet room.

[0025] Therefore, according to the residential air conditioning system of the sixth aspect of the invention, the fan constituting the blower and the motor constituting the fan can be small or low-power, and the generation of noise can be sufficiently suppressed. Furthermore, the outdoor air supplied into the house through the outdoor air inlet duct, outdoor air supply duct, and air inlet is heat-exchanged with the air (air in the adjacent room) moving from the indoor air suction duct to the indoor air exhaust duct by the heat exchange element, and then supplied into the specific space in which the indoor unit is installed, so that an extremely efficient air conditioning effect can be achieved not only in the specific space but also in the adjacent rooms. This is also true in a house where the adjacent room is adjacent to the other adjacent rooms. In other words, according to the residential air conditioning system of the sixth invention, in which the blower is disposed between the specific space and an adjacent room and the air discharged from the indoor unit is supplied to the adjacent room, there is no need to use ducts as in the conventional art, which are troublesome, costly, and reduce the ceiling height. In addition, the blower itself can be small or low-output, which greatly reduces the cost of installing the air conditioning equipment, including the air conditioner, or the construction cost of the house including this, and can also greatly contribute to shortening the construction period of the house.

[0026] Furthermore, the seventh invention (the invention described in claim 7) is characterized in that, in the sixth invention described above, there is one indoor unit that is installed in the specific space and that constitutes the air conditioner for the entire house, and there is also one outdoor unit installed outside the house corresponding to this indoor unit.

[0027] According to the residential air conditioning system of the seventh aspect of the present invention, the air conditioning system can be introduced at even lower cost. Effect of the Invention

[0028] The blower of the present invention and a residential air conditioning system equipped with this blower not only make it possible to significantly reduce the number of indoor units and outdoor units that make up the air conditioner, but also eliminate the need for ducts at all to move air from the indoor units to each room, and further reduce the effort required for construction without lowering the ceiling height of spaces (specific spaces) such as corridors where the indoor units are located, thereby significantly reducing the introduction costs, including construction costs.
