Abstract
The present invention discloses a ceiling indoor machine of an air conditioner, which comprises a casing, a blowing fan, an evaporator and a motor, wherein the casing is fixed in a room ceiling, the blowing fan is arranged in the cabinet, and the motor drives the blowing fan. Cold air flowing spaces are formed among two side walls of the casing and the evaporator, and the lower ends of the cold air flowing spaces are respectively provided with a discharge port. The lower parts of the two side walls of the casing respectively incline outwards, and the longitudinal section of the casing forms a trapezoid of which the upper part is narrow and the lower part is wide. Thereby, the cross section area of the cold air flowing space formed between the evaporator and the outer wall of the cabinet gradually increases from top to bottom. The present invention has the advantages that the ceiling indoor machine enlarges cold air quantity, decreases the flow rate of cold air, lowers noise and fast and evenly diffuses the cold air so as to provide comfort and cool indoor environment.
Description
Technical field
The present invention relates to a kind of air-conditioner, particularly relate to a kind of indoor machine of air-conditioner.
Background technology
Common separation formula air-conditioner generally comprises indoor set and off-premises station two parts, indoor set by evaporimeter to the room air cooling that circulates; Off-premises station is by the refrigerant of condensing machine cooled flow in above-mentioned evaporimeter and pipeline.Several forms such as that indoor set has is wall-hanging, vertical type and ceiling type.
As shown in Figure 1, the ceiling type indoor machine of air-conditioner comprises: be inserted and secured on casing 10 in the room ceiling, be arranged on blowing fans 12 in the casing 10, be arranged on blowing fan 12 the next door evaporimeter 14 and drive the drive motors 16 of blowing fan 12.
Said fan 12 is a kind of centrifugal type electric fan, is made up of wind deflector 121 and a plurality of fan blade 122 of being assemblied on the above-mentioned wind deflector 121.The lower central position of described casing 10 is provided with suction inlet 10a, forms horn mouth 101 between above-mentioned wind deflector 121 and the suction inlet 10a.
Above-mentioned evaporimeter 14 is located at the left and right sides of blowing fan 12, is respectively equipped with an outlet 10b between two sidewalls of casing 10 and the evaporimeter 14.After suction inlet 10a inhaled air process evaporimeter 14 coolings that are positioned at above-mentioned horn mouth 101 centers, discharge by outlet 10b.
Above-mentioned outlet 10b links to each other with the port of cold air flow space 10c, and transversal basal area and the outlet 10b of cold air flow space 10c are roughly the same.
The course of work of common air-conditioning device ceiling type indoor machine is, blowing fan 12 rotates under the driving of drive motors 16, indoor warm air is inhaled in the casing 10 by suction inlet 10a, through evaporimeter 14 coolings, cooled air is discharged outside casing 10 by outlet 10b through cold air flow space 10c, suitably the temperature in the conditioning chamber.
From the installation site of above-mentioned ceiling type indoor machine as can be seen, the cold air of discharging to the outside of casing 10 is than the low and diffusion downwards naturally of external air temperature of normal temperature, and the discharge pressure that need not to improve blowing fan 12 also can relatively reduce indoor temperature with producing effect.
According to above-mentioned prior art as can be seen, because the air that is drawn in the casing 10 by suction inlet 10a disperses to the left and right by blowing fan, after evaporimeter 14 coolings, discharge by the less outlet 10b of cross-sectional area again, therefore, it is big to form mobile other form indoor set cold air flow velocity under the identical situation of air quantity of one-way air than those in casing 10.
Therefore, above-mentioned common ceiling type indoor machine has following defective: the cold air flow velocity is too fast, and noise is big during startup, simultaneously because the deficiency in draught of discharging can't spread cold air equably very soon in the interior space.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cross-sectional area of cold gas exhausting outlet big, reduce the air-conditioner ceiling type indoor machine that noise also can spread cold air quickly and evenly.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: comprising: be inserted and secured on casing in the room ceiling, be installed in the drive motors of blowing fan, evaporimeter and driving blowing fan in the casing.
Described blowing fan is a kind of centrifugal type electric fan, is made up of wind deflector and a plurality of fan blade of being assemblied on the above-mentioned wind deflector.The lower central position of described casing is provided with suction inlet, forms horn mouth between above-mentioned wind deflector and the suction inlet.
Form the cold air flow space between two sidewalls of described casing and the evaporimeter, the lower end in cold air flow space is respectively equipped with an outlet.After the suction inlet inhaled air process evaporator cools that is positioned at above-mentioned horn mouth center, discharge by outlet.
The bottom of two sidewalls of described casing is outward-dipping respectively, and it is up-narrow and down-wide trapezoidal that the longitudinal section of casing is.
Thereby make the cross-sectional area in the cold air flow space that forms between evaporimeter and the casing outer wall increase gradually from top to bottom.
Advantage of the present invention is: increased the cross-sectional area of cold gas exhausting outlet, the cold air air quantity is strengthened, reduced the flow velocity of cold air, both can reduce noise, can spread cold air equably again, so that comfortable nice and cool indoor environment to be provided.

The specific embodiment
Below in conjunction with the drawings and specific embodiments this present invention is described in further detail:
As shown in Figure 2, the ceiling type indoor machine of air-conditioner of the present invention comprises: be arranged on casing 10 on the room ceiling, be installed in blowing fan 12, evaporimeters 14 in the casing 10 and be used for driving the drive motors 16 of blowing fan 12.
Described blowing fan 12 is a kind of centrifugal type electric fan, is made up of wind deflector 121 and a plurality of fan blade 122 of being assemblied on the above-mentioned wind deflector 121.The lower central position of described casing 10 is provided with suction inlet 10a, forms horn mouth 101 between above-mentioned wind deflector 121 and the suction inlet 10a.
Form cold air flow space 10d between two sidewalls of described casing and the evaporimeter, the lower end of cold air flow space 10d is respectively equipped with outlet 10b.After suction inlet 10a inhaled air process evaporimeter 14 coolings that are positioned at above-mentioned horn mouth 101 centers, discharge by outlet 10b.
The bottom of two sidewalls of described casing 10 is outward-dipping respectively, and it is up-narrow and down-wide trapezoidal that the longitudinal section of casing 10 is.
Thereby make the cross-sectional area of the cold air flow space 10d that forms between evaporimeter 14 and casing 12 outer walls increase gradually from top to bottom.
After the air-conditioner ceiling type indoor machine of the specific embodiment of the invention was activated, blowing fan 12 was drawn into room air in the casing 10, after evaporimeter 14 coolings, flow to cold air flow space 10d, discharged from outlet 10b then.Cold air in flowing space 10d in outlet 10b moving process, reduced noise on outlet 10b because of flow velocity slows down,, made the cold air air quantity increase simultaneously because cold air flow space 10d is up-narrow and down-wide, come thereby Quilt with air conditioning is spread quickly and evenly, improved freezing capacity.
