Abstract
The present invention discloses a ventilation arrangement for indoor unit of cabinet air-conditioner comprising an air intake grille for air intake arranged on lower part of the positive surface of the shell, an air exhaust grille for exhausting heat exchanged air arranged on upper part of the positive surface of the shell; an air feeding fan for forcing circulation of air indoors arranged on lower part inside the shell; a heat exchanging device is arranged on the air feeding fan, a cool air reflecting plate is arranged at right angle corner position on rear part of the hollow chamber inside of the shell, a second heat exchange device is arranged in front of the cool air reflecting plate upside of the heat exchanging device. The invention has available effect of: when cool air generated by heat exchanging device flows to cool air reflecting plate having concave column face by the air feeding fan, the cool air reflecting plate guiding the cool air to air exhaust grille and the cool air is exhausted into chamber, which improves the refrigeration efficiency.
Description
Technical field
The present invention relates to a kind of air-conditioner, particularly relate to a kind of exhaust structure of cabinet type air conditioner indoor machine.
Background technology
As everyone knows, air-conditioner has the household electrical appliance of refrigeration, pyrogenicity function, can create a comfortable indoor environment for the user.According to its mounting means, air-conditioner can be divided into several types such as window air conditioner, wall-hanging air conditioner, ceiling-mounted air conditioner and cabinet air conditioner.Wherein cabinet air conditioner is by indoor set and off-premises station two large divisions, and its indoor set is installed on the indoor floor, and off-premises station is installed in outdoor.
As shown in Figure 1, the structure of existing cabinet type air conditioner indoor machine is generally: the bottom of outer casing frontispiece is provided with the suction grille 2 that is used for sucking room air; The top of outer casing frontispiece is provided with and is used for to the air discharge grille 3 of indoor discharging through the air of heat exchange; Shell
The bottom of inside be provided with and be used for the blowing fan 4 of forced circulation room air; Be provided with heat exchanger 5 above the blowing fan 4.
The refrigeration course of work to above-mentioned existing cabinet type air conditioner indoor machine is illustrated below: after the air-conditioner energising started, blowing fan 4 began rotation, and room air is inhaled in the shell by suction grille 2 under the suction that blowing fan 4 produces; Meanwhile, compressor (not shown) in the off-premises station is started working, to be compressed also, condensed refrigerant flows to heat exchanger 5 by the refrigerant pipe, refrigerant evaporates in heat exchanger 5 and carries out heat exchange with the room air that is inhaled into, the cold air that produces through heat exchange is discharged into indoor from air discharge grille 3 under the effect of blowing fan 4, said process moves in circles, and finally makes indoor temperature keep suitable temperature.
The shortcoming of above-mentioned existing cabinet type air conditioner indoor machine is: be inhaled into the room air of shell and heat exchanger 5 and carry out the cold air that produces after the heat exchange, under the effect of blowing fan 4, at first upwards flow, the cuboid that is shaped as owing to shell 1, there is the right angle corner position in the last rear portion of shell 1 internal cavities, cold air can produce eddy current when upwards flowing to this right angle corner position, make cold air can not be successfully from air discharge grille 3 to indoor discharging, influenced the freezing capacity of air-conditioner.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of above-mentioned existing cabinet type air conditioner indoor machine, and a kind of cold air drainage exhaust structure of cabinet type air conditioner indoor machine smoothly is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the exhaust structure of cabinet type air conditioner indoor machine of the present invention is: the bottom of outer casing frontispiece is provided with the suction grille that is used for sucking room air; The top of outer casing frontispiece is provided with and is used for to the air discharge grille of indoor discharging through the air of heat exchange; The bottom of the inside of shell is provided with and is used for the blowing fan of forced circulation room air; Be provided with heat exchanger above the blowing fan, the right angle corner position at the last rear portion of enclosure cavity is provided with the cold air reflecting plate, and the place ahead of the top cold air reflecting plate of heat exchanger is provided with second heat exchanger.
Described cold air reflecting plate is the concave cylindrical face towards the surface of air discharge grille.
The invention has the beneficial effects as follows: simple in structure, easy to make; Because the right angle corner position at the last rear portion of enclosure cavity is provided with the cold air reflecting plate, the cold air that produces through heat exchange upwards flows under the effect of blowing fan, when cold air flow is the cold air reflecting plate of concave cylindrical face to the surface, no longer produce eddy current, the reflex of cold air reflecting plate is with the cold air air discharge grille that leads swimmingly, then through air discharge grille to indoor discharging, improved the freezing capacity of air-conditioner.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
The exhaust structure of cabinet type air conditioner indoor machine of the present invention is: the bottom of outer casing frontispiece is provided with the suction grille 2 that is used for sucking room air; The top of outer casing frontispiece is provided with and is used for to the air discharge grille 3 of indoor discharging through the air of heat exchange; The bottom of the inside of shell is provided with and is used for the blowing fan 4 of forced circulation room air; Be provided with heat exchanger 5 above the blowing fan 4, the right angle corner position at the last rear portion of enclosure cavity is provided with cold air reflecting plate 8, and the place ahead of the top cold air reflecting plate 8 of heat exchanger 5 is provided with second heat exchanger 7.
Described cold air reflecting plate 8 is the concave cylindrical face towards the surface of air discharge grille 3.
The course of work to the exhaust structure of cabinet type air conditioner indoor machine of the present invention is illustrated below: after the air-conditioner energising started, blowing fan 4 began rotation, and room air is inhaled in the shell by suction grille 2 under the suction that blowing fan 4 produces; Meanwhile, compressor (not shown) in the off-premises station is started working, to be compressed also, condensed refrigerant flows to heat exchanger 5 by the refrigerant pipe, refrigerant evaporates in the heat exchanger 5 and second heat exchanger 7 and carries out heat exchange with the room air that is inhaled into, the cold air that produces through heat exchange upwards flows under the effect of blowing fan 4, when cold air flow is the cold air reflecting plate 8 of concave cylindrical face to the surface, no longer produce eddy current, the reflex of cold air reflecting plate 8 is with the cold air air discharge grille 3 that leads swimmingly, then through air discharge grille 3 to indoor discharging, improved the freezing capacity of air-conditioner.
