Description

The present invention relates to an indoor unit and a refrigerating cycle device including a panel in which a first suction port and a second suction port provided inside the first suction port are formed.

Conventionally, for example, in an indoor unit of a ceiling-embedded air conditioner, a suction panel, which is a central member, is installed in the center of a suction port formed in the lower part of a housing. By covering the suction port, the suction panel makes it difficult to see the inside of the housing and blocks the sound generated from the inside of the housing. As described above, conventionally, an indoor unit of an air conditioner that reduces noise while ensuring designability has been proposed. However, by installing the suction panel, the area of the suction port is reduced, and a dead water area is generated on the inner surface of the housing of the suction panel due to the separation of the air flow, and the ventilation resistance is increased. Therefore, the input power of the fan motor increases, and the energy saving property deteriorates.

For the purpose of ensuring energy saving, Patent Document 1 discloses a ceiling-embedded indoor unit in which an auxiliary opening is formed in a suction panel provided at the center of an annular suction port. As a result, the indoor unit of Patent Document 1 aims to expand the suction area and reduce the dead water area, reduce the ventilation resistance, and suppress the increase in the input power of the fan motor.

However, since the indoor unit disclosed in Patent Document 1 is provided with an auxiliary opening for ensuring energy saving, the sound generated from the blower or the like is likely to leak to the outside through the auxiliary opening. Therefore, in Patent Document 1, the sound insulation of the suction panel is lowered, and the low noise effect cannot be sufficiently obtained.

The present invention has been made to solve the above-mentioned problems, and provides an indoor unit and a refrigerating cycle device having improved sound insulation while ensuring energy saving.

In the indoor unit according to the present invention, an opening is formed on the air-conditioned space side, and the main body attached to the attached portion, the first suction port for sucking air, and the central side of the main body from the first suction port. A second suction port that is formed to suck in air, a first suction port, and an outlet that blows out the air sucked from the second suction port are formed, and a panel that covers the opening of the main body and a first suction port are formed. It is provided with a blower forming a flow of air sucked in from the mouth and the second suction port and blown out to the outlet, and a wind guide wall provided so as to cover at least a part of the second suction port of the panel. The panel was provided inside the decorative panel and the decorative panel covering the edge of the opening, and formed a first suction port between the decorative panel and the decorative panel, and a second suction port was formed in the central portion. It has a suction panel, and the air guide wall is provided on the blower side of the panel.

According to the present invention, since the air guide wall is provided in the second suction port, it is possible to suppress the sound inside the main body from leaking to the outside through the second suction port. Therefore, even if the second suction port is formed in the panel in order to reduce the ventilation resistance and secure the energy saving, the sound insulation can be improved. That is, the indoor unit can improve the sound insulation while ensuring energy saving.

Further, since a dead water area is generated on the inner surface of the main body 20 of the suction panel 7 due to the separation of the air flow and the ventilation resistance is increased, the input power of the fan motor 2 may be increased and the energy saving property may be deteriorated. Therefore, in the first embodiment, the frame-shaped suction panel 7 is adopted, whereby the second suction port 22 inside the frame-shaped suction panel 7 is formed, the suction area is expanded, and the dead water area is expanded. Is reduced. As a result, the ventilation resistance is reduced, and the increase in the input power of the fan motor 2 is suppressed. However, in this state, the sound generated from the blower 18 or the like may leak to the outside through the second suction port 22. Therefore, in the first embodiment, by providing the air guide wall 23 at the second suction port 22, the sound inside the main body 20 is directly radiated to the outside through the second suction port 22. It can be suppressed. As described above, the first embodiment can achieve both the improvement of energy saving and the improvement of sound insulation.

Further, the air guide wall 23 has an area equal to or larger than the opening area of the second suction port 22, and is installed so as to cover the second suction port 22 in a plan view from below the indoor unit 200. ..

Embodiment 4.
FIG. 10 is a circuit diagram showing a refrigeration cycle device 1000 according to a fourth embodiment of the present invention. In the fourth embodiment, the refrigeration cycle apparatus 1000 having the indoor units 200 of the first to third embodiments will be described. As shown in FIG. 10, the refrigerating cycle device 1000 is, for example, an air conditioner that adjusts the air in the air-conditioned space 17, and includes an outdoor unit 100 and an indoor unit 200. The outdoor unit 100 and the indoor unit 200 are connected by a gas pipe 300 through which a gas refrigerant flows and a liquid pipe 400 through which a liquid refrigerant or a gas-liquid two-phase refrigerant flows. The outdoor unit 100 is provided with a compressor 101, a flow path switching device 102, an outdoor heat exchanger 103, an outdoor blower 104, and an expansion unit 105. The indoor unit 200 is provided with a heat exchanger 3 and a blower 18.

A compressor 101, a flow path switching device 102, an outdoor heat exchanger 103, an expansion unit 105, and a heat exchanger 3 are connected by a connecting pipe to form a refrigerant circuit. The compressor 101 sucks in a refrigerant in a low temperature and low pressure state, compresses the sucked refrigerant into a refrigerant in a high temperature and high pressure state, and discharges the sucked refrigerant. The compressor 101 is provided with, for example, an inverter device or the like, and the capacity of the compressor 101 is finely changed by arbitrarily changing the operating frequency. Here, the capacity of the compressor 101 is the amount of the refrigerant delivered per unit time. The flow path switching device 102 switches the direction in which the refrigerant flows in the refrigerant circuit based on an instruction from the control device (not shown), and is, for example, a four-way valve. The outdoor heat exchanger 103 exchanges heat between, for example, outdoor air and a refrigerant. The outdoor heat exchanger 103 acts as a condenser during the cooling operation and as an evaporator during the heating operation.

The outdoor blower 104 is a device that sends outdoor air to the outdoor heat exchanger 103. The outdoor blower 104 may be, for example, a centrifugal fan 1 or the like similar to the blower 18. The outdoor blower 104 may arbitrarily change the operating frequency of the motor by an inverter device or the like to finely change the rotation speed of the centrifugal fan 1.

It exchanges heat with the outdoor air sent by 104 to form a condensed liquefaction. The condensed liquid-state refrigerant flows into the expansion unit 105 and is expanded and depressurized in the expansion unit 105 to become a low-temperature and low-pressure gas-liquid two-phase state refrigerant. Then, the refrigerant in the gas-liquid two-phase state flows into the heat exchanger 3 acting as an evaporator, and in the heat exchanger 3, heat is exchanged with the indoor air sent by the blower 18 to be converted into evaporative gas. At this time, the indoor air is cooled, and cooling is performed indoors. The evaporated low-temperature and low-pressure gas-state refrigerant passes through the flow path switching device 102 and is sucked into the compressor 101.

(Operation mode, heating operation)
Next, the heating operation will be described. In the heating operation, the refrigerant sucked into the compressor 101 is compressed by the compressor 101 and discharged in a high temperature and high pressure gas state. The high-temperature and high-pressure gas-state refrigerant discharged from the compressor 101 passes through the flow path switching device 102, flows into the heat exchanger 3 acting as a condenser, and is sent by the blower 18 in the heat exchanger 3. It exchanges heat with the indoor air to be condensed and liquefied. At this time, the indoor air is warmed and heating is performed in the room. The condensed liquid-state refrigerant flows into the expansion unit 105 and is expanded and depressurized in the expansion unit 105 to become a low-temperature and low-pressure gas-liquid two-phase state refrigerant. Then, the refrigerant in the gas-liquid two-phase state flows into the outdoor heat exchanger 103 that acts as an evaporator, and in the outdoor heat exchanger 103, heat is exchanged with the outdoor air sent by the outdoor blower 104 to become evaporative gas. The evaporated low-temperature and low-pressure gas-state refrigerant passes through the flow path switching device 102 and is sucked into the compressor 101.

As described above, by configuring the outdoor unit 100 with the blowers 18 of the first to third embodiments as the outdoor blowers 104, it is possible to realize an efficient outdoor unit 100.

The indoor unit 200 may be an indoor unit 200 of the refrigeration cycle device 1000, for example, an indoor unit 200 of an air conditioner. Further, the indoor unit 200 as a blower device without the heat exchanger 3 may be used.
