Detailed Description

The utility model is described in detail below by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The air conditioner includes an outdoor unit, which refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, and an indoor unit of the air conditioner including the indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

The indoor unit is connected to an outdoor unit installed in an outdoor space through a pipe. The outdoor unit may be provided therein with a compressor, an outdoor heat exchanger, an outdoor fan, an expander, and the like of a refrigeration cycle, and the indoor unit may be provided therein with an indoor heat exchanger and an indoor fan.

Referring to fig. 1 to 5, the indoor unit of an air conditioner in this embodiment includes a casing, a fresh air module 1, and a heat exchange module.

The cabinet is installed in the indoor space, in which a plurality of components constituting a refrigeration cycle are installed, and defines the overall appearance of the air conditioning indoor unit, including side surfaces defining a side configuration, a bottom surface defining a bottom configuration, and a top surface defining a top configuration.

Fresh air module 1 and heat exchange module all set up in the inside of casing, and fresh air module 1 sets up the one end in the spiral case is inside. The fresh air module 1 is used for sending outdoor fresh air to the indoor and conveying the fresh air to the indoor. The heat exchange module is used for exchanging heat of the indoor unit of the air conditioner to indoor air.

The fresh air module 1 is provided with a fresh air inlet 11 and a fresh air outlet 12. The fresh air outlet 12 is communicated to the indoor space.

The fresh air outlet 12 of the fresh air module 1 is provided with a filter screen 2, and the filter screen 2 is used for filtering air flowing through the fresh air outlet 12 and preventing impurities in outdoor air from flowing indoors.

Filter screen 2 can slide from top to bottom in new trend export 12 departments, and when filter screen 2 slided the below, filter screen 2 was in the closure state with new trend export 12, does not have the clearance between filter screen 2 and new trend export 12 promptly, and when the new trend was out of the wind, the new trend could flow to the interior space after filter of filter screen 2. When filter screen 2 slided the top, filter screen 2 broke away from new trend export 12, had the clearance between filter screen 2 and new trend export 12 promptly to when making the new trend air-out, the new trend need not pass through filter screen 2's filtration alright discharge to the interior space.

In this embodiment, be provided with slide 3 on the lateral wall of new trend module 1, slide 3 is connected with filter screen 2 net, and slide 3 can be followed the lateral wall of new trend module 1 and is up-and-down reciprocating motion to drive filter screen 2 and slide from top to bottom so that filter screen 2 breaks away from new trend export 12 or make filter screen 2 and new trend export 12 closed.

The sliding plate 3 is provided with a rack portion 31, the outside of the fresh air module 1 is provided with a gear 5 and a motor 4, the motor 4 is fixed on the outer side wall of the fresh air module 1, the output shaft of the motor 4 is fixedly connected with the center of the gear 5, and the gear 5 is meshed with the rack portion 31. When the motor 4 rotates, the gear 5 can be driven to synchronously rotate, and the gear 5 drives the rack part 31 to slide upwards or downwards through meshing, so as to drive the sliding plate 3 to slide upwards or downwards.

The air conditioner indoor unit can drive the filter screen 2 to do reciprocating motion through the sliding plate 3, so that when the outdoor air quality is good, the motor 4 rotates to enable the sliding plate 3 to drive the filter screen 2 to move, a gap is generated between the fresh air outlet 12 and the filter screen 2, outdoor fresh air can directly flow into an indoor space without passing through the filter screen 2, and therefore fresh air volume is improved.

Since the rack portion 31 is engaged with the gear 5, and is in a long-term stressed state, the slide plate 3 is provided with the reinforcing rib 32, and the reinforcing rib 32 is connected to the rack portion 31, so that the structural strength of the rack portion 31 is enhanced, and the service lives of the rack portion 31 and the slide plate 3 are prolonged. In this embodiment, the reinforcing rib 32 is provided perpendicular to the rack portion 31 to better enhance the structural strength of the rack portion 31.

In this embodiment, filter screen 2 is connected with water conservancy diversion structure 6, and water conservancy diversion structure 6 is used for the air-out of dispersion new trend. The water conservancy diversion structure 6 is connected in the one side of filter screen 2 back to the air-out direction, and water conservancy diversion structure 6 is connected in the one side that is close to the interior space of filter screen 2 promptly to when making new trend module 1 to indoor air-out, the new trend after filter screen 2 is dispersed through the water conservancy diversion effect of water conservancy diversion structure 6, makes the new trend wider at indoor air supply range.

In this embodiment, water conservancy diversion structure 6 sets up to hopper-shaped structure, and along the air-out direction of new trend, the opening 61 of water conservancy diversion structure 6 crescent to play the effect of better dispersion water conservancy diversion new trend. The minimum of opening 61 of water conservancy diversion structure 6 is in the middle part fixed connection of filter screen 2 to when the new trend is out of the wind, disperse the new trend from the middle part of filter screen 2 to all around evenly.

In other embodiments of the present invention, the filter screen 2 and the flow guiding structure 6 are integrally formed, so that the installation steps of the filter screen 2 and the flow guiding structure 6 can be reduced, and the connection strength between the filter screen 2 and the flow guiding structure 6 can be improved.
