Problems solved by technology

Therefore, in order to realize the miniaturization of product size and performance improvement, in the aspect of the product design that needs to set the fan diameter to the maximum, especially near the central part of the upper side of the blowing grille, the sealing member protrudes toward the air passage side and obstructs Blowing out by the fan causes noise and hinders aerodynamic performance

Embodiment approach 1

[0024] figure 1 It is an external perspective view of the outdoor unit of the air-conditioning apparatus according to Embodiment 1 of the present invention, figure 2 means removed figure 1 A perspective view of the state of the top panel, image 3 From figure 2 A perspective view viewed obliquely from the opposite side, Figure 4 yes figure 1 top view. In addition, in the following description, the front side of a drawing is called a front side, the back side is called a back side, the left side is called a left side, and the right side is called a right side.

[0025] exist Figure 1 ~ Figure 4 Among them, 1 represents the casing of the outdoor unit, which consists of a bottom plate with legs 2a on the lower surface, a substantially L-shaped front panel 3 provided from the front side to the left side, and a side panel 4 provided from the right side to a part of the back side. , and the substantially L-shaped heat exchanger 5 provided from the back side to the inside ...

Embodiment approach 2

[0039] Figure 7 It is a perspective view which shows the state which removed the top panel of the outdoor unit of the air-conditioning apparatus concerning Embodiment 2 of this invention. In addition, the same code|symbol is attached|subjected to the part which is the same as Embodiment 1, or has the same function.

[0040] In Embodiment 1, the case where the eaves 16 are provided on the edge of the portion corresponding to the blowing grill 8 on the front side of the top panel 15 is shown, but in this embodiment, the top panel 15 is provided on the front side. The edge part of the whole is provided with the eaves part 16.

[0041] Also in this embodiment, substantially the same effects as in the case of Embodiment 1 can be obtained.

Embodiment approach 3

[0043] In this embodiment, the outdoor unit in Embodiment 1 or 2 is connected to an indoor unit installed indoors through refrigerant piping and electrical wiring, thereby constituting an air-conditioning apparatus.

[0044] Also in this embodiment, substantially the same effects as in the case of Embodiment 1 can be obtained.

Abstract

In the outdoor unit including: a casing (1) having a substantially parallelepiped shape opened on top; a top panel (15) configured to close the opening on the top of the casing (1); a bell mouth (7) provided at an outlet opening of a propeller fan (30) formed on a front panel (3) which constitutes the casing (1); an outlet grill (8) attached on the front side of the outlet opening; and an appentice (16) provided at an end portion of the top panel (3) at a portion corresponding to the outlet grill (8) on the front side of the top panel (3) so as to be overhung to the front from the edge portion.

Description

technical field [0001] The present invention relates to an outdoor unit of an air conditioner and an air conditioner including the outdoor unit. Background technique [0002] In the outdoor unit of the air conditioner, during heating operation, water droplets formed by rain, snow, etc. adhering to the front panel, and water droplets formed by melting snow accumulated on the outdoor unit fall along the surface of the front panel and soak into the horn. between the port and the fan. [0003] Moreover, when the outside air temperature is low, the temperature of the air blown out by the fan may become below the freezing point. In this case, the water droplets immersed between the bell mouth and the fan freeze, and when the amount of water droplets is large, the formed ice grows and contacts with the fan. There are problems such as abnormal noise generated by the contact of the fan, or disturbance of rotation, thereby causing abnormal stop of the outdoor unit. [0004] In order...
