Embodiment

As shown in Figure 1, a kind of fresh air purifier on the window, including host 2 and it is generally rectangular tabular knot The stent 1 of structure, as shown in Fig. 2, host 2 includes shell, display screen 202 and control button 203 are provided with its front panel 22, Side is provided with enabling 201, and enabling 201 is mainly used for closing filter core and picks and places mouth, is convenient for changing and cleans filter core.As shown in figure 3, Wind exhausting outlet 205 and fresh inlet 206 are provided with the backboard 21 of host, wind exhausting outlet 205 and fresh inlet 206 are grid Hole, can enter host to avoid foreign matters such as winged insects.The top of host 2 is provided with fresh-air fan 209 and fresh air outlet 204, fresh air Export the deflector 210 for being set at 204 and carrying inclined back plate.

As Figure 4-Figure 6, host 2 is internally provided with heat exchanger 3, and heat exchanger 3 includes two groups of heat exchange pipes 31, lower seat 32 With the seat of honour 33, heat exchange pipe 31 is arranged vertically, and faces fresh inlet 206, and the quantity of certain heat exchange pipe can also be more than Two groups, but need to meet the requirement that adjacent row heat exchanger tube is staggered, host inner space is made full use of to reach, is increased as far as possible The purpose of heat exchange efficiency.

Lower seat 32 and the seat of honour 33 are hollow structure, are connected respectively with the wind exhausting outlet 205 on host, air draft import 207. The seat of honour 33, lower seat 32, heat exchange pipe 31 and backboard 21 define filtering chamber 211 closed at both ends, so-called closed at both ends to be Referring to air will not appear from filtering chamber 211, can only advance from fresh inlet 206 to heat exchange pipe 31, which not only simplifies Structure, and reduce energy loss.

The inside filling filter core (not shown) of filtering chamber 211, filter core were mainly used for the particulate matter in air filtering And other harmful substances matter, for ease of replacing and safeguarding, set in the side of filtering chamber and pick and place mouth.Filter core is generally tied in the form of sheets Structure, is provided with multilayer, the nuisance of every layer of absorption is different, so as to achieve the purpose that integrated treatment.

To achieve the purpose that sealing, the seat of honour 33 blocks the gap between backboard 21 and heat exchange pipe 31, as shown in fig. 6, under Seat 32 includes hypomere 321 and epimere 322, and epimere 322 blocks the gap between heat exchange pipe 31 and front panel 22, hypomere 321 Block the gap between front panel 22 and backboard 21.31 both ends of heat exchange pipe are separately fixed on the seat of honour 33 and epimere 322.

As shown in fig. 6, hypomere 321 is internally provided with centrifugal blower 323, realizes and force air draft, improve heat exchange efficiency, hypomere The position of 321 bottom surface face centrifugal blower 323 is equipped with inlet scoop 324, has at inlet scoop 324 and inwardly prolongs secondary venturi Pipe, can improve air draught efficiency., can will be cold in addition, the periphery of inlet scoop is provided with osculum 325, and external drainpipe 329 Condensate is discharged in time.

The side of hypomere 321 is equipped with return air inlet 326, and as shown in Figures 3 and 4, backboard 21 is provided with gate at return air inlet 326 327,327 both sides of gate and the sliding slot of 326 both sides of return air inlet coordinate, and can move up and down, drive rod 328 passes through pin and gate 327 connect, and the bar-shaped trough being slidably matched with pin is provided with drive rod 328, and by driving stepper motor.When drive rod 328 When being rotated around motor output shaft, pin slides along bar-shaped trough, and gate is upwardly opened or closed downwards.

As shown in figure 4, backboard 21 is hollow structure, inner cavity is connected with return air inlet 326.When Outdoor Air Quality is too low, newly Wind clarifier can be to circulate in opening section, and gate 327 moves up, and return air inlet 326 is opened, room air through lower seat 32 from Heart wind turbine 322 aspirates, and enters from return air inlet 326 in the inner cavity of stent 1, then returns to filtering chamber again with extraneous air 211.The interior of backboard 21 can certainly be only entered, returns filtering chamber 211.

As shown in FIG. 7 and 8, stent is the epimere 12 and hypomere 11 for including mutually being socketed, both are hollow platy structure, Wherein, hypomere 11 has air inlet 110, air outlet 111 and return air inlet 112, and front is provided with hook 113.Internal stent Gas spring 14 is equipped between hypomere 11 and epimere 12, both can be made to be restored automatically after compressing, in addition to gas spring, certainly Other resetting-mechanisms such as helical spring can also be used.The top of epimere 12 is additionally provided with end cap 13, by the end part seal of epimere 12.

As shown in fig. 7, when stent is compressed to ultimate attainment, end cap 13 is connected with hypomere 11, and whole stent 1 is rectangle, and Surfacing.In order to allow stent to keep the state, the present embodiment is also provided with through the latch of epimere 12 and hypomere 11 (in figure not Show), prevent stent 1 from restoring automatically, be easily installed.

As figs 11-13, the C-type steel at fixed 14 both ends of gas spring is separately provided for inside epimere 12 and hypomere 11 121 and C-type steel 114, the limit hole coordinated with 14 end of gas spring is equipped with C-type steel, biside plate is closed with rack inner wall face paste, And it is bolted.

As shown in figs. 9-10, be connected to C-type steel 131,115 in the upper and lower ends of stent 1, respectively as with window sliding The sliding slot that rail 4 coordinates, the width of C-type steel 131,115 and the thickness of stent are basically identical.As shown in figure 5, in C-type steel 131,115 Bottom surface there is elastomeric pad 132, elastomeric pad is generally made of resin energy elastic material.The present embodiment is on elastomeric pad surface There is provided multiple grooves set along bracket slide direction, during slip, the slide of window can block in the trench, prevent stent 1 Sway forwards and backwards.

As shown in FIG. 7 and 8, hook 113 is made up of the panel of stent 1 of punching and punching press, is integrally formed with stent. Hook number on stent 1 has four, and point two rows of arrangements, correspond with the hanging hole 212 at 2 back side of host and set.

Utility model works principle is as follows：

After stent is compressed, the C-type steel 115 of bottom is stuck in through on the slide of lower edge, then takes out latch, allows stent 1 Automatic to restore, the C-shaped channel 131 on top is stuck on window on the slide on edge, then by 2 carry of host on stent 1, that is, completes peace Dress.Can certainly be in advance by 2 carry of host on stent 1, then mounting bracket 1 again.

During work, fresh air enters the inner cavity of backboard 21 from fresh inlet 206, subsequently into filtering chamber 311, filter core By heat exchange pipe 31 after filtering, heat exchange is carried out with the outdoor air of discharge, then is delivered up from 204 discharge of fresh air outlet. Due to the effect of centrifugal blower 323, indoor air enters host from air draft import 207, then in turn through lower seat 32, heat exchange Comb 31, the seat of honour 33, outdoor is discharged to from wind exhausting outlet, by heat exchange occurs with fresh air outside during heat exchange pipe 31.

When outside air quality is not high, interior circulation can be opened, opens gate 327, air draft just enters from return air inlet 326 props up The inner cavity of frame 11, enters back into filtering chamber 311 and filters again, also has the entrance of portion of external fresh air at this time certainly.To carry High indoor air quality, the cavity 308 of filling filtering material is also provided with the inner side of air draft import 307.
