Fig. 7 is the partial perspective view that illustrates from the air-flow of discharging according to the indoor set of embodiment of the present invention.
Referring to Fig. 7, be provided with outlet at the downside of indoor set 1, lay out mouth and be equipped with and discharge grill unit 20.More specifically, carry out air discharged through discharge grill unit 20 and discharge to the right and left, and wide dispersion.
In addition, primary blades 18 and back blades 19 rotatably each other coupling join in outlet.Gap between front panel 12 and the outlet is blocked by contrary wind stopper section 17.
More specifically, if drive installation at the inner fan component of indoor set 1, so most of room airs suck from the upper surface of indoor set 1, yet also have little air to suck through the front surface of indoor set 1.Said little air sucks through the gap that is formed between front panel 12 and the outlet, and the part of air of discharging from outlet also can flow to the gap again.In order to prevent that this contrary wind phenomenon from taking place, stopper section 17 against the wind is installed on the bottom of moving framework 153.And, the gap between against the wind stopper section 17 is blocked the lower end that is formed on front panel 12 and exported.Therefore, bump against stopper section 17 against the wind because a part is discharged into the air of outlet, thereby prevent the phenomenon that air flows to indoor set inside again.
Simultaneously, primary blades 18 have fully the width that hides stopper section 17 against the wind and with the corresponding length of length of outlet.And the rear end of the rear end of primary blades 18 and back blades 19 rotatably is coupled to a side of discharging grill unit 20.If primary blades 18 is closed, then stopper section 17 is covered with back blades fully against the wind.And if the operational order of input indoor set 1, back blades 19 rotates to open outlet along opposite directions with primary blades 18 so.At this, back blades 19 can begin to rotate after primary blades 18 is opened fully.In other method, back blades can turn to just in primary blades 18 and begin after not receiving back blades view of disturbances scope to rotate.
In addition, can back blades 19 be set for according to refrigeration mode and heating mode and have the different rotation angle.For example in heating mode, the rotational angle of back blades 19 is set for relative to the rotational angle in the refrigeration mode, makes the warm air of discharging can be discharged into ground, room.On the contrary, in refrigeration mode, the rotational angle of back blades 19 is set for relative to the rotational angle in the heating mode, and air can be discharged in the space of room upside.Because summer, hot-air was distributed in upside and cold air is distributed in downside, therefore reach the purpose of rapid cooling thermal air and Fast Heating cold air like this.
To describe 19 the method for operating that joins relation and back blades with the coupling of back blades 19 in detail with reference to accompanying drawing.
Fig. 8 is the exterior perspective view of formation according to the central frame of the indoor set of embodiment of the present invention, and Fig. 9 is the face upwarding stereogram that the filter guiding structural that is arranged in the central frame is shown.
Referring to Fig. 8 and Fig. 9, central frame 13 is arranged in the indoor set 1, and wherein front panel 12 is coupled to the front surface of central frame 13 and underframe 11 is coupled to the back surface of central frame 13.
More specifically, central frame 13 comprises: grid body 131; Be arranged on the filter installation portion 133 on the front surface of grid body 131; And be formed on the last grid 132 on the upper surface of grid body 131.Upper surface and most of institute inhaled air that last grid 132 basically forms indoor set 1 pass grid 132.
In addition, on a lateral edges of grid body 131, be formed with control cabinet containing hole 136, wherein on the upper edge of control cabinet containing hole 136, be formed with panel rod guidance portion 134 and panel hinge hole 135.Panel hinge hole 135 is formed on the isolated position, top with panel rod guidance portion 134.And, on the bottom of two side surfaces, be formed with coupling and join hook 137 with predetermined elastic force.
In addition, filter guide ribs 138 is formed on the bottom surface of grid 132 and bends to and has predetermined curvature with the protrusion mode.And when extraction filter 16 is back to its initial position with it then, slide along filter guide ribs 138 in the top of filter 16.And, filter 16 is inserted into correct position by means of filter guide ribs 138.So the part of filter 16 is positioned at the downside of grid 132, and remainder is positioned on the front surface of filter installation portion 133.Therefore, filter to pass heat exchanger by filter 16 through the front surface portion of indoor set 1 and the room air of last grid 132 suctions.
Those of ordinary skills should be understood that, can easily utilize in the above description disclosed design to revise or design as the basis with the specific embodiment and be used to realize other embodiment identical with the object of the invention.Those of ordinary skills it is to be further understood that this embodiment that is equal to does not deviate from and likes the spirit and scope of the present invention that propose in the claim enclosed.
