Abstract
The invention relates to an air conditioner, in particular to a structure used for reducing resonance and noise of a cabinet-typed air conditioner indoor machine; the structure solves the problems that the rear wall of a casing of the existing cabinet-typed air conditioner indoor machine used for fixing the fan motor is easy to generate the resonance and noise when the fan motor runs owning to large area and thin material. The structure comprises a chassis, a cabinet-shaped casing consisting of a front casing and a rear casing and a top cover which are arranged at the upper side of the chassis, a front panel which is arranged in front of the front casing, grids, a filter and a plasma dust collector which are arranged at the center of the front panel and air inlets at the lower part of the two sides, grids and grilles which are arranged at the center of the front panel and the exhaust outlet at the upper part of the two sides, a heat exchanger which is obliquely arranged in the water receiving disc at the upper part of the rear casing, a centrifugal fan wind guide cover which is arranged on the lower surface of the water receiving disc, and a fan motor which is arranged on the rear wall of the casing behind the wind guide cover. In order to eliminate the resonance and noise generated when the fan motor runs, the rear wall of the casing is also provided with radial reinforced ribs.
Description
Technical field
The invention relates to air regulator, particularly a kind of structure for reducing resonance noise of cabinet air conditioner indoor unit.
Background technology
Generally, for comfortable environment more is provided to the user, refrigerant compression, release cycle loop that the air-conditioner utilization is made of compressor, condenser, expansion valve, evaporimeter to indoor cooling and warming or purify air, and roughly are divided into split type and monoblock type.
Split type identical on function with monoblock type, still, split type is that cooling or heat-releasing device are set in indoor set, and heat release or cooling and compression set are set in off-premises station; Monoblock type is with cooling or heat release function integration, burrows on the wall in room or directly installation on window.
Existing split cabinet type air conditioner indoor set STRUCTURE DECOMPOSITION figure as shown in Figure 1, it includes chassis 73, vertical synthetic cabinet shape casing 66 and the top cover 65 of front and back casing that be provided with of 73 upside on the chassis, the front and the top, two sides that are combined in casing 66 are formed with front exhaust outlet 104a and two side exhaust outlet 104c separately, adjust the direction of the air of discharging by side exhaust outlet 104c when opening and closing side exhaust outlet 104c, two upper lateral parts of plate 104 are installed the left and right blinds that can rotate up and down in front.
In order to suck air in front between plate 104 central lower and the chassis 73, design has installs grid 47,74 and filter 75, plasma dust arrester 78 assemblies on front air inlet 41 and bottom air inlet 77 and front air inlet 41 and the bottom air inlet 77.
In the existing indoor apparatus of air conditioner of above-mentioned formation, if feed electric power then fan electromotor 68, and fan 69 drive, the air of indoor flow into indoor set inside by above-mentioned following grid 74 and air cleaner 75, and air by plasma dust arrester 78 time foreign substances such as dust be ionized and assembled and have in one's care, air is delivered to heat exchanger 52 by fan 69 afterwards.
Be sent to that the air of heat exchanger 52 carries out heat exchange with refrigerant wherein and after being cooled or heating, be expelled back into again by front exhaust outlet 104a and side exhaust outlet 104c and indoorly carry out indoor refrigeration or heat.
But fan 69, the fan electromotor 68 of existing indoor apparatus of air conditioner are fixed on the rear wall of casing 66, the running vibration of fan electromotor can cause the resonance of casing, and the resonance of casing produces bigger resonance noise, resonance can cause air-conditioner to damage, noise can influence people's health, thereby has also reduced the product image degree and the market competitiveness.
Summary of the invention
The present invention is in order to solve existing existing the problems referred to above of cabinet type air conditioner indoor set, and a kind of structure for reducing resonance noise of cabinet air conditioner indoor unit is disclosed, its technical scheme includes: chassis, cabinet shape casing and the top cover be made up of front housing and back cabinet that are provided with at the chassis upside; The front panel that front housing is provided with previously; The grid, filter, the plasma dust arrester that are provided with on front panel central authorities and the two side lower part air inlets; Grid and blinds that front panel central authorities and both sides upper air vent are provided with; Be obliquely installed the heat exchanger in the drip tray of back cabinet top; Be arranged at the centrifugal fan wind scooper below the drip tray, be installed on fan electromotor on the casing rear wall of wind scooper back with screw; On the resonance that produces when eliminating fan motor runs and its casing rear wall of noise also design the radiation ribs is arranged.
Above-mentioned radiation ribs can be designed as M shape, Ж font.
The center of above-mentioned radiation ribs is consistent with fan electromotor shell center, bubbling inwardly or external mold be pressed into.
Clamped concavo-convex, the corresponding elastic damping pad of shape between said machine casing rear wall and fan electromotor.
Advantage and good effect: the present invention is in casing rear wall fan electromotor mounting center position, design radiation ribs, the thin casing rear wall stiffness of material is strengthened, when fan motor runs, no longer produce resonance, therefore reduced the damage of resonance to air-conditioner, noise has improved the product image degree and the market competitiveness to the harmful effect of human body.
