Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem that intermittent noise is generated due to an increase of draft resistance and the fostering of turbulence of a flow when the suction resistance of a panel end of a suction opening is increased by an influence of a sidewall, and suction performance is deteriorated. <P>SOLUTION: This air conditioner is equipped with a body 1 including a heat exchanger 2, and a blow fan 3 blowing out air heat-exchanged by the heat exchanger 2 from a blowout opening. By having a panel 5 covering the heat exchanger 2 in a front face of the body 1, moving the panel 5 forward to form suction parts 10a, 10b in an upper part and a lower part, and enlarging the lower suction part 10b at both ends 7 in a longitudinal direction of the body 1, even if both ends 7 are common areas with large draft resistance, draft performance can be improved by mitigating the draft resistance, and the intermittent abnormal noise caused by the turbulence of the flow generated due to the draft resistance of both ends 7 being large can be suppressed. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an air conditioner.

A conventional air conditioner of this type includes an air inlet, a heat exchanger, and a blower fan that takes in indoor air from the air inlet and blows out the air heat-exchanged by the heat exchanger from the air outlet. The air intake port has a configuration in which the front surface of the main body is covered with a panel and can be sucked from the upper and lower portions of the panel. Alternatively, as shown in FIG. 7, due to the movement of the panel, the lower intake port is closed when stopped, and the lower intake port is opened during operation (see, for example, Patent Document 1). .
Japanese Patent No. 3897804

  However, in the structure of the conventional air conditioner, since the suction port at the lower part of the panel is the same in the longitudinal direction, the suction resistance at the end increases due to the influence of the side wall, and the suction performance is deteriorated. Furthermore, the ventilation resistance is increased and the flow disturbance is promoted, so that intermittent noise may be generated. In addition, if the suction from the central portion in the longitudinal direction, which is the mainstream, is not sufficient, a large air flow performance cannot be improved.

  The present invention provides an air conditioner that solves the above-described conventional problems, changes the suction port at the bottom of the panel in the longitudinal direction, suppresses the generation of intermittent abnormal noise, and has excellent airflow performance. Objective.

  In order to solve the conventional problems, an air conditioner of the present invention includes a main body with a built-in heat exchanger, and a blower fan that blows out air that has been heat-exchanged by the heat exchanger from an outlet. A panel that covers the heat exchanger on the front surface of the front panel, the panel is moved forward, and suction portions are provided in the upper and lower portions, and the suction portions from the lower portion are enlarged at both longitudinal ends of the main body. It is characterized by that.

  By the means described above, even in a region where the airflow resistance is generally large at both ends, the airflow resistance is relaxed and the blowing performance can be improved. Furthermore, the intermittent abnormal sound due to the flow turbulence generated due to the large ventilation resistance at both ends can be suppressed.

  A first invention includes a main body with a built-in heat exchanger, and a blower fan that blows out air heat-exchanged by the heat exchanger from a blow-out port, and has a panel that covers the heat exchanger on the front surface of the main body. Then, the panel is moved forward, suction portions are provided at the upper and lower portions, and the suction portions from the lower portion are enlarged at both longitudinal ends of the main body. For example, the suction part is enlarged by making the position of the lower part of the panel of both ends higher than the center part. Thereby, even in a region where the airflow resistance is generally large at both ends, the airflow resistance is relaxed and the airflow performance is improved. Furthermore, the intermittent abnormal sound due to the flow turbulence generated due to the large ventilation resistance at both ends can be suppressed.

2nd invention is comprised with the main body which incorporated the heat exchanger, the ventilation fan which blows off the air heat-exchanged with the said heat exchanger from a blower outlet, a stabilizer, and a rear guider, The said heat exchange is carried out in the front of the said main body. A suction cover is provided at the upper and lower parts by moving the panel forward, and the suction part from the lower part is enlarged at the central part in the longitudinal direction of the main body. For example, the suction performance is improved by making the position of the lower portion of the center panel higher than both ends. As a result, the suction resistance is reduced at the central portion of the main blower, and the air flow performance can be further improved.

  According to a third invention, in the first invention, the central portion in the longitudinal direction of the panel is formed in a concave shape so that the suction portions at both ends in the longitudinal direction of the main body are enlarged. With this configuration, the suction height at the bottom of the panel as viewed from the front is kept constant, so that the design can be maintained. In general, even in a region where the airflow resistance at both ends is large, the airflow resistance is relaxed and the airflow performance is improved. Furthermore, the intermittent abnormal sound due to the flow turbulence generated due to the large ventilation resistance at both ends can be suppressed.

  According to a fourth aspect, in the second aspect, the central portion in the longitudinal direction of the panel is convex so that the suction portion in the central portion in the longitudinal direction of the main body is enlarged. With this configuration, the suction height at the bottom of the panel as viewed from the front is kept constant, so that the design can be maintained. As a result, the suction resistance is reduced at the central portion of the main blower, and the air flow performance can be further improved.

  According to a fifth invention, in the first to fourth inventions, a partition plate is provided inside so that the heat exchanger cannot be seen from the suction portion at the lower part of the panel. For example, by increasing the height of the flange of the water tray, the heat exchanger is made invisible even when looking up from the suction port at the bottom of the panel. With this configuration, design properties can be improved.
