Described off-premises station 30 also comprises the top panel 39 that forms the top outward appearance, and top panel 39 utilizes the screw (not shown) to be fixed on the backplate 45.
Fig. 3 is the STRUCTURE DECOMPOSITION schematic diagram of the fire proof construction specific embodiment of the control panel of air-conditioner outdoor unit of the present invention.
As shown in Figure 3, the fire proof construction of the control panel of air-conditioner outdoor unit of the present invention comprises: demarcation strip 33, control panel 41 and flameproof enclosure 51,55; As indicated above, described demarcation strip 33 is arranged on the chassis 31 of off-premises station 30, is used for dividing the inner space of off-premises station 30; Described control panel 41 is arranged in the inner space of off-premises station 30 of demarcation strip 33 1 sides, and control panel 41 is provided with electronic unit 42,43; Control panel 41 generally adopts injection molding process to make by the synthetic resin material; The effect of described electronic unit 42,43 is the control signals that are used for receiving from the control part (not shown) of air conditioner room unit, and controls the duty of off-premises station 30 according to the control letter that receives.
Described flameproof enclosure 51,55 is arranged on the control panel 41, described electronic unit 42,43 is enclosed in its inside, its effect is when preventing electronic unit 42,43 at work because of overheated catching fire flame to be delivered to the miscellaneous part of indoor set 30 inside, and can prevent electronic unit 42,43 to be subjected to external impact and damage.
Described flameproof enclosure 51,55 usefulness metal materials are made, and roughly are the cuboid box-shape of bottom surface opening.But, as long as will be delivered to flame the miscellaneous part of indoor set 30 inside in the time of can preventing electronic unit 42,43 at work because of overheated catching fire, and can prevent parts 42,43 to be subjected to external impact and damage, described flameproof enclosure 51,55 can be made with other material, also can form other shapes.
The lower edge of described flameproof enclosure 51,55 is formed with two respectively and connects lugs 52,54, and the effect that connects lug 52,54 is to be fixed on the control panel 41 being used for the flameproof enclosure 51,55 of electronic unit 42,43; Described connection lug 52,54 preferably is arranged on respectively on the opposed facing edge of flameproof enclosure 51,55 lower ends in couples.
Be formed with connecting hole 53,56 respectively on the described connection lug 52,54; Be formed with the connecting hole 53,56 that corresponds respectively to the connecting hole 53,56 that connects lug 52,54 on the described control panel 41; Respectively screw Sa, Sb are run through the connecting hole 53,56 that connects lug 52,54 and the connecting hole 53,56 of control panel 41, and tighten screw Sa, Sb, just described flameproof enclosure 51,55 has been fixed on the control panel 41.
Effect to the fire proof construction of the control panel of air-conditioner outdoor unit of the present invention is illustrated below:
At first, after the air-conditioner energising starts, the control part of indoor set transmits control signal according to the electronic unit 42,43 of operation signal on the control panel 41 that is arranged on off-premises station 30 of user's input, and electronic unit 42,43 is according to the duty of these signal of telecommunication control off-premises stations 30.
Specifically, under the control of electronic unit 42,43, described compressor 39 is compressed into the HTHP gaseous coolant with the gaseous coolant in the coolant circulating system of air-conditioner, Air Blast fan 37 flows into the off-premises station space with outdoor air from suction hole 45a, and makes the outdoor air that is inhaled into and the refrigerant of outdoor heat converter 35 inside carry out heat exchange.
In said process, described electronic unit 42,43 can produce certain heat, and the working time has been grown or electronic unit 42,43 when itself having defective, and electronic unit 42,43 can be because overheated and catch fire.
Because described control panel 41 generally makes with the synthetic resin material, thus when electronic unit 42,43 when overheated and on fire, control panel 41 is easy to be lighted.But, because the flameproof enclosure 51,55 that is arranged on the control panel 41 is closed electronic unit 42,43, thereby the propagation of flame that has prevented electronic unit 42,43 and control panel 41 has been played good flameproof effect to the miscellaneous part of off-premises station 30 inside.
As mentioned above, basic fundamental of the present invention is contemplated that, comes for the propagation of flame that causes of catching fire of the electronic unit on the control panel that prevents to be arranged on air-conditioner outdoor unit, and control panel is provided with the flameproof enclosure with the electronic unit sealing.
According to above-mentioned basic fundamental design; those of ordinary skill in the art need not can associate change and modification to the specific embodiment of the invention through creative work; perhaps associate some other specific embodiment, these all belong to protection scope of the present invention.
