Detailed description of the invention
The invention provides a kind of air-conditioning and indoor set air-inlet grille thereof, heating the heating effect of start-up phase to reach raising air-conditioning, avoiding air-conditioning uneven at this one-phase leaving air temp, improve the object of air conditioning comfortableness.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, the decomposition texture schematic diagram of the indoor apparatus of air conditioner air-inlet grille that Fig. 1 provides for the embodiment of the present invention; The front view of electric boiling plate in the indoor apparatus of air conditioner air-inlet grille that Fig. 2 provides for the embodiment of the present invention.
A kind of indoor apparatus of air conditioner air-inlet grille that the embodiment of the present invention provides, comprises mesh grille plate 1 and electric boiling plate 6.
Wherein, electric boiling plate 6 is arranged on mesh grille plate 1, mesh grille plate 1 is provided with fresh air inlet 2, electric boiling plate 6 is provided with exhaust vent 7, and fresh air inlet 2 is communicated with exhaust vent 7.
Compared with prior art, the indoor apparatus of air conditioner air-inlet grille that the embodiment of the present invention provides, in air-conditioning start-up phase, electric boiling plate 6 is opened and is heated, preheating is carried out to the air-conditioning air intake through mesh grille plate 1 fresh air inlet 2, thus raising air-conditioning is heating the leaving air temp of start-up phase, compared with electric heater unit being installed in prior art the mode of indoor set inside, electric heater unit and air-inlet grille are integrated together by the present invention, not only save space, be convenient to the installation of electric heater unit, and electric boiling plate 6 is directly installed on mesh grille plate 1, without the need to considering installation site and setting angle, can to the air intake homogeneous heating through mesh grille plate 1, thus ensure the uniformity of air-out, effectively can improve air-conditioning and heat the heating effect of start-up phase, improve air conditioning comfortableness.
Fresh air inlet 2 on mesh grille plate 1 both can align with the exhaust vent 7 on electric boiling plate 6 and arrange, also can be crisscross arranged with exhaust vent 7 on electric boiling plate 6, but when fresh air inlet 2 to align with exhaust vent 7 arrange time, air-conditioning air intake is when electric boiling plate 6, speed, less with the contact area of electric boiling plate 6, electric boiling plate 6 is caused to give full play to effect, finally cause pre-heat effect undesirable, therefore, in embodiments of the present invention, effect is given full play in order to make electric boiling plate 6, improve pre-heat effect, realize the object of rapidly pre-warming, in embodiments of the present invention, fresh air inlet 2 and exhaust vent 7 are crisscross arranged, and a fresh air inlet 2 is at least communicated with two exhaust vents 7, like this, air-conditioning air intake is after passing through the fresh air inlet 2 on mesh grille plate 1, first the position between two exhaust vents 7 on electric boiling plate 6 is bumped against, obtain deceleration to a certain extent, thus increase contact area and the time of contact of air-conditioning air intake and electric boiling plate 6, electric boiling plate 6 is made to give full play to effect, the temperature of rapid raising air-conditioning air intake, reach raising pre-heat effect, the object of rapidly pre-warming.
Fresh air inlet 2 and exhaust vent 7 are crisscross arranged, harmful effect may be caused to the intake of air-conditioning, affect heat pump performance, therefore, in order to optimize technique scheme further, in embodiments of the present invention, some first air-permeating holes 5 are offered, by offering the first air-permeating hole 5, under the prerequisite not affecting air-conditioning intake and serviceability between exhaust vent 7 adjacent on electric boiling plate 6, further add the heat exchange efficiency of electric boiling plate 6, realize the object of rapidly pre-warming.
During air conditioner refrigerating, when evaporator surface temperature is lower than space air dew-point temperature, steam in air can condense at evaporator surface, form condensed water, this part condensed water under gravity, fall into evaporimeter water-collecting tray, then by outside condensate pipe discharge chamber, because condensed water derives from evaporator surface, its temperature is lower, directly by outside its discharge chamber, not only can cause pollution to a certain degree to surrounding environment (as building wall), the residue cold in condensed water also can be caused to be fully utilized, cause the waste of the energy, therefore, in embodiments of the present invention, electric boiling plate 6 is provided with desuperheating coil 9, the outlet of desuperheating coil 9 is communicated with air conditioner condensation water pipe, import is connected with the water pump for pumping condensed water, like this, when air conditioner refrigerating, electric boiling plate 6 is closed, the condensed water of A/C evaporator is delivered in desuperheating coil 9 by water pump and carries out precooling to air-conditioning air intake, thus reduce indoor set leaving air temp, the residue cold in condensed water is utilized to improve the refrigeration of air-conditioning, improve air-conditioning efficiency.
Further, in embodiments of the present invention, the outlet of desuperheating coil 9 and import be all arranged at electric boiling plate 6 away from mesh grille plate 1 side on the surface.
In actual heating process, electric boiling plate 6 both can keep at a certain distance away with mesh grille plate 1 and arrange, also can fit with mesh grille plate 1 and arrange, in embodiments of the present invention, in order to save space, electric boiling plate 6 was both fitted with mesh grille plate 1, but because mesh grille plate 1 generally adopts plastic production, when electric boiling plate 6 is fitted with mesh grille plate 1, the heat of electric boiling plate 6 easily causes mesh grille plate 1 to damage, therefore, in order to optimize technique scheme further, in embodiments of the present invention, refer to Fig. 3, the front view of thermal insulation board in the indoor apparatus of air conditioner air-inlet grille that Fig. 3 provides for the embodiment of the present invention, thermal insulation board 3 is also provided with between electric boiling plate 6 and mesh grille plate 1, position corresponding with the exhaust vent 7 of electric boiling plate 6 on thermal insulation board 3 is provided with through hole, by arranging the high temperature injury mesh grille plate 1 that thermal insulation board 3 can effectively prevent electric boiling plate 6 from producing, ensure the service life of air-conditioning air-inlet grille.
Further; in order to improve the service life of each parts in indoor apparatus of air conditioner; in embodiments of the present invention; thermal insulation board 3 is also provided with the filter 4 for filtering air inlet; like this; thermal insulation board 3 can either play the function that the netted flase floor 1 of protection is not electrically heated plate 6 infringement, can filter again, effectively can protect the safety of each parts in running in air-conditioning to air-conditioning.
In order to avoid causing harmful effect to air-conditioning air intake, in embodiments of the present invention, offer some second air-permeating holes 8 between through hole adjacent on thermal insulation board 3, the second air-permeating hole 8 on thermal insulation board 3 is arranged with the first air-permeating hole 5 one_to_one corresponding on electric boiling plate 6.
Present invention also offers a kind of air-conditioning, refer to Fig. 4, the structural representation at the air-conditioner indoor unit panel place that Fig. 4 provides for the embodiment of the present invention, comprise indoor set, the panel 10 of indoor set is provided with air outlet 11 and air-inlet grille, wherein, air-inlet grille is the indoor apparatus of air conditioner air-inlet grille as above described in any one.
