Description

Saddle type window machine

Technical Field

The utility model relates to the technical field of air conditioners, in particular to a saddle type window machine.

Background

The saddle type window machine comprises an indoor unit, an outdoor unit and a saddle bridge, wherein the saddle bridge connects the indoor unit with the outdoor unit, and the indoor unit is separated from the outdoor unit through the saddle bridge so as to separate the indoor unit from the outdoor unit, effectively reduce indoor noise, and enable the saddle bridge to be located at a window to realize installation of the saddle type window machine at the window.

In the fixed-frequency saddle type window machine, an electric cabinet is arranged in a saddle bridge, and the inner space of the saddle bridge is fully utilized. However, in the variable-frequency saddle window machine, the electric cabinet is larger than the electric cabinet in the fixed-frequency saddle window machine due to the fact that the electric cabinet is larger in size, so that the electric cabinet in the variable-frequency saddle window machine cannot be installed in the saddle bridge, and the electric cabinet can be installed in the outdoor unit. When the variable frequency window machine works, the electric cabinet generates a large amount of heat, and electric components in the electric cabinet need to be rapidly cooled so as to ensure the reliable operation of the electric cabinet. The electric cabinet in the existing window machine is only provided with a single ventilation heat dissipation opening on the shell, and is not effectively combined with the air path in the outdoor machine, so that the heat dissipation effect is poor.

In some embodiments of the present application, the heat dissipation air path of the electric cabinet 400 is combined with the heat dissipation air path of the outdoor unit 200 on the basis of the improvement of the back air inlet and the bottom air outlet of the heat dissipation air path of the electric cabinet 700, so as to further improve the heat dissipation effect of the electric cabinet 400.

Specifically, as described above, referring to fig. 1 and 2, the back plate 250 of the outdoor unit 200 is provided with the outdoor rear air inlet 213, and the front side of the outdoor unit 200 is provided with the heat exchanger and the outdoor front air outlet 211. The electric cabinet 400 is disposed near the rear backplate 250, and a gap is formed between the bottom of the electric cabinet 400 and the bottom chassis 270 of the outdoor unit 200.

External air flows into the outdoor unit 200 from the outdoor rear air inlet 213, and as the electric cabinet 400 is closely arranged on the rear back plate 250, and the air inlets (specifically, the first air inlet 451 and the second air inlet 452) are arranged at the rear part of the electric cabinet 400, part of cold air entering from the outdoor rear air inlet 213 directly enters the electric cabinet 400 through the air inlets (specifically, the first air inlet 451 and the second air inlet 452), then flows out from the air outlet 460 at the bottom of the electric cabinet 400, heat in the electric cabinet 400 is taken away, and hot air flowing out from the bottom of the electric cabinet 400 is discharged out of the outdoor unit along with heat dissipation airflow of the outdoor unit 200, so that the discharge of the heat dissipation airflow of the electric cabinet 400 is further improved, and the heat dissipation efficiency is improved.

The first air inlet 451 is arranged opposite to the outdoor rear air inlet 213, and the cold air flowing in from the outdoor rear air inlet 213 directly flows into the first air inlet 451, so that the cold air inflow of the electric cabinet 400 is improved, and the heat dissipation effect is improved.

A gap is arranged between the bottom of the electric cabinet 400 and the chassis 270, and the air flowing out from the air outlet 460 at the bottom of the electric cabinet 400 is discharged through the gap, so that the chassis 270 is prevented from blocking the discharge of the heat dissipation air.

The heat dissipation air flow of the electric cabinet 400 is combined with the heat dissipation air flow of the outdoor unit 200, so that on one hand, outdoor cool air can quickly enter the electric cabinet 400 in a large amount, and on the other hand, hot air discharged from the bottom of the electric cabinet 400 can be quickly discharged along with the heat dissipation air flow of the outdoor unit 200 without being blocked by the chassis 270, thereby achieving the effect of quick heat dissipation of the electric cabinet 400.

In some embodiments of the present application, the top wall, the left side wall, and/or the right side wall of the outdoor unit 200 are/is provided with an outdoor side air inlet, and as described above, the air inlets on the left side wall, the right side wall of the outdoor unit 200 are referred to as an outdoor side air inlet 212, and the air inlet on the top wall of the outdoor unit 200 is referred to as an outdoor top air inlet 214.

The outdoor unit 200 adopts a four-side air inlet mode, increases the air inlet quantity, and is beneficial to improving the heat dissipation effect of the outdoor unit 200 and the electric cabinet 400.

In some embodiments of the present application, referring to fig. 4, the heat dissipating fins 490 on the electric cabinet 400 extend toward the front side of the outdoor unit 200, the top sides of the heat dissipating fins 490 communicate with the outdoor top air inlet 214 without obstruction, and the side portions of the heat dissipating fins 490 communicate with the outdoor side air inlet 212 without obstruction.

The heat radiating fins 490 absorb heat of the circuit board 471, and cold air flowing in through the outdoor top air inlet 214 and the outdoor side air inlet 212 directly acts on the heat radiating fins 490, which helps to improve heat radiating efficiency of the heat radiating fins 490, thereby improving heat radiating effect of the electric cabinet 400.
