Detailed Description

In the indoor unit of the air conditioner provided by the related art, one driving part is connected with only one air inlet plate, and only one air inlet plate can be driven by one driving part to open or close the air inlet. The existing indoor unit is provided with at least two air inlets for the multidirectional air inlet. Because the number of the air inlet plates is consistent with that of the air inlets, the existing indoor unit needs to be provided with a plurality of driving parts to drive the plurality of air inlet plates respectively. Not only causes an increase in the weight of the indoor unit, but also causes a large energy consumption of the air conditioner.

In view of this, according to the panel and the air conditioner provided by the embodiments of the present invention, through the driving plate disposed between the two air inlet plates, the two sets of connecting rod assemblies disposed between the driving plate and the two air inlet plates, and the driving portion for sliding the driving plate, one driving portion can synchronously drive the two air inlet plates to rotate, so that the two air inlets are synchronously opened or closed.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

For convenience of description, the present embodiment takes the direction indicated by the arrow X in the drawings as the left, and the direction opposite to the X direction as the right; taking the direction indicated by an arrow Y as front and the direction opposite to the Y direction as back; the direction indicated by the arrow Z is up, and the direction opposite to the Z direction is down.

The air conditioner provided by the embodiment of the utility model comprises an indoor unit and an outdoor unit. The outdoor unit may be installed on the ceiling of a room or may be installed outdoors. As shown in fig. 1, the indoor unit can be hung from the ceiling of a room by means of a cross member 8. The indoor unit realizes circulation of indoor air through the fan, and regulates and controls the temperature of the indoor air through the evaporator. Fig. 1 is a perspective view of an indoor unit of an air conditioner according to an embodiment of the present invention, and fig. 2 is a sectional view of the indoor unit of the air conditioner shown in fig. 1, wherein fig. 1 and 2 show a state in which an air intake panel 1 is closed. As shown in fig. 1 and 2, the indoor unit includes a casing 3 and a panel 1. The housing 3 and the panel 1 enclose an accommodating space for installing the fan 32 and the evaporator 33.

With continued reference to fig. 2, in particular, the housing 3 may comprise a hollow prism body with an open bottom end, and the prism body may comprise a top wall and a side wall connected to the outer periphery of the top wall and extending downward. The panel 1 may be disposed at the bottom end of the prism and may close the opening of the prism, so that the panel 1 and the housing 3 may enclose an accommodating space.

Specifically, the panel 1 may include a base 11, and the base 11 may include a bottom wall and a side wall. The side wall of the base 11 is connected to the outer periphery of the bottom wall of the base 11 and extends upward. The lateral wall setting of shell 3 is in the outside or the inboard of the lateral wall of base 11, and the lateral wall of shell 3 is connected with the lateral wall accessible block connection of base 11, detachable modes such as fastening connection to the maintenance of the spare part in the accommodation space that shell 3 and base 11 and surround.

Arrows in fig. 2 indicate flow paths of indoor air. In fig. 2, the panel 1 is provided with an air inlet 112 and an air outlet 113. A fan shell 31 is arranged in the accommodating space, an air outlet channel 7 communicated with an air outlet 113 of the panel 1 is formed on the inner side of the fan shell 31, and an air inlet channel 6 communicated with an air inlet 112 of the panel 1 is formed between the outer side of the fan shell 31 and the inner side of the shell 3.

Specifically, the air outlet 113 of the panel 1 is disposed on the bottom wall of the base 11, and the air inlet 112 of the panel 1 is disposed on the bottom wall of the base 11 and/or the side wall of the base 11. To increase the intake of air from the panel 1, the side walls and bottom wall of the base 11 may be provided with air intakes 112 (as shown in fig. 2). In addition, the above-mentioned fan case 31 is disposed in the accommodating space and extends in the vertical direction. The upper end of the fan shell 31 is provided with an air inlet, and the lower end of the fan shell 31 is provided with an air outlet. The evaporator 33 is covered outside the air inlet of the fan housing 31, and the fan 32 is arranged in the fan housing 31. The lower end of the fan shell 31 is embedded in the air outlet 113 of the panel 1, or the lower end of the fan shell 31 is sleeved outside the air outlet 113 of the panel 1, so that the air outlet at the lower end of the fan shell 31 is communicated with the air outlet 113 of the panel 1. Fig. 2 shows an example in which the lower end of the fan case 31 is fitted in the air outlet 113 of the panel 1.

Referring to fig. 2, air is guided by the blower 32 and enters the air intake passage 6 through the air inlet 112 of the panel 1. The air in the air inlet channel 6 passes through the evaporator 33 and exchanges heat with the evaporator 33, and then enters the air outlet channel 7, namely the inside of the fan casing 31. Finally, the air flows out from the air outlet 113 of the panel 1.

It should be noted that, in order to increase the intake air amount and the intake air range of the panel 1, a plurality of intake openings 112 may be provided, and a plurality of intake openings 112 may be distributed on the periphery of the outlet 113. The at least two air intakes 112 may be symmetrical about a first imaginary plane. The first imaginary plane is an imaginary plane, which refers to a line or plane of symmetry between two adjacent air inlets 112. I.e. the first imaginary plane can bisect the line connecting the symmetry points of the two air inlets 112. In addition, after the two air inlets 112 symmetrically arranged are folded in half with respect to the first imaginary plane, the two air inlets 112 may completely coincide, or one of the air inlets 112 is inside the other air inlet 112, or the two air inlets 112 partially coincide.

Each intake vent 112 is rotatably mounted with an intake panel 14. In order to reduce the number of driving parts for driving the air inlet panel 14 to rotate, the driving parts may be disposed on a first imaginary plane between the two symmetrical air inlets 112, so that the driving parts can synchronously drive the two symmetrical air inlet panels 14 to rotate to synchronously open or close the two air inlets 112.

It should be noted that the number of the air inlets 112 may be two, or may exceed two. Fig. 2 illustrates that the intake ports 112 are provided in two, and the two intake ports 112 are respectively provided symmetrically with respect to the axial plane of the outlet port 113 so as to fit the arrangement of the evaporator 33 mentioned below. The axial plane of the outlet 113 refers to a plane that can bisect the outlet 113 into a left part and a right part. That is, the axial surface of the outlet 113 is a plane that can bisect the front wall surface and the rear wall surface of the outlet 113.

When three air inlets 112 are provided, the three air inlets 112 may be arranged in a triangle, that is, the three air inlets 112 may be disposed at three vertices of the triangle. At least two of the air inlets 112 are each rotatably equipped with an air inlet plate 14, which will be described later. In order to reduce the number of the above-mentioned driving portions for driving the rotation of the air inlet panel 14, two adjacent air inlets 112, in which the air inlet panel 14 is respectively disposed, may be symmetrical with respect to a first imaginary plane, and the driving portion may be disposed on the first imaginary plane between the two adjacent air inlets 112. In addition, the third air inlet 112 of the three air inlets 112 may be provided with the air inlet plate 14 or not provided with the air inlet plate 14. When the third air inlet 112 is provided with the air inlet plate 14, it can be driven by a separate driving part.

When four air inlets 112 are provided, the four air inlets 112 may be arranged in a quadrilateral manner, that is, the four air inlets 112 are respectively provided at four vertices of the quadrilateral. The four intake vents 112 may each be provided with an air intake panel 14, or two of the four intake vents 112 may be provided with an air intake panel 14, or three of the four intake vents 112 may be provided with an air intake panel 14. When the four air inlets 112 are provided with the air inlet plates 14, connecting lines among the four air inlets 112 can form a parallelogram, two of the four air inlets 112 are symmetrical, and the symmetrical axes are diagonal lines of the parallelogram. The two driving parts are respectively arranged at two ends of the diagonal line, and each driving part can synchronously drive the air inlet plates 14 at two sides of the driving part to rotate.

Of course, the number and arrangement of the air inlets 112 may be other various types, which are only illustrated and not specifically limited herein. However, it is desirable that at least two of the air inlets 112 are symmetrical with respect to the first imaginary plane so that the driving portions are synchronized such that the two symmetrical air inlets 112 are opened or closed simultaneously.

As shown in fig. 2, since the evaporator 33 is covered on the air inlet 112 of the fan housing 31, the width of the air inlet 112 of the fan housing 31 should be as large as possible to increase the heat exchange rate of the evaporator 33. In fig. 2, the width of the air inlet 112 of the fan housing 31 is larger than the width of the air outlet 113 of the fan housing 31, so as to increase the air inlet amount and increase the air outlet rate. The width of the air inlet 112 of the fan housing 31 refers to a distance between two ends of the air inlet 112 of the fan housing 31 in the direction of the X axis. Similarly, the width of the air outlet 113 of the fan housing 31 refers to the distance between two ends of the air outlet 113 of the fan housing 31 in the direction of the X axis. Optionally, at least a portion of the evaporator 33 is located within the intake vent 112 of the panel 1 in projection with respect to the panel 1, so as to reduce the intake path of the air. Exemplarily, in fig. 2, the two air inlets 112 are symmetrical about the axis of the air outlet 113, the left and right sides of the evaporator 33 are located outside the fan housing 31, and the projections of the left and right sides of the evaporator 33 are respectively inside the left and right two air inlets 112. In addition, optionally, a filterable member 4 is provided in the air intake passage 6 to purify the indoor air.

The construction of the air inlet panel 14 will now be described.

When the air inlet 112 is closed by the air inlet panel 14, the air inlet 112 can be completely closed by the air inlet panel 14, and part of the air inlet 112 can also be closed by the air inlet panel 14. Illustratively, fig. 2 is a schematic view of the intake vent 112 in a closed state, and in fig. 2, a part of the intake vent 112 is disposed on the bottom wall of the base 11, and another part of the intake vent 112 is disposed on the side wall of the base 11. When the air inlet 112 is closed by the air inlet panel 14, the air inlet panel 14 is in a horizontal position to close a portion of the air inlet 112 located in the bottom wall of the base 11. While the portion of the intake vent 112 located on the side wall of the base 11 is still open, so as to provide the smallest intake vent 112 of the panel 1. In addition, in order to smooth the air flow when the air inlet panel 14 is rotated to open the partial air inlets located on the bottom wall, as shown in fig. 1 and 2, the partial air inlets 112 located on the side wall of the base 11 communicate with the partial air inlets 112 located on the bottom wall of the base 11, that is, when the air inlet panel 14 closes the partial air inlets 112 located on the bottom wall, that is, when the air inlet panel 14 is in the horizontal position, the lower ends of the partial air inlets 112 located on the side wall are formed by the air inlet panel 14.

Since the plurality of air inlets 112 are disposed around the air outlet 113, in order to prevent air entering from the air inlets 112 and air flowing out of the air outlet 113 from interfering with each other, an end of each of the air inlet plates 14 remote from the air outlet 113 is rotated toward the air outlet 113 when the air inlets 113 are opened. That is, the air inlet panel 14 can always rotate between the air inlet 112 and the air outlet 113 to block air crosstalk. For example, in fig. 2, the air outlet is disposed between the two air inlets, and the rotation directions of the two air inlet plates are opposite. For example, the air inlet panel 14 on the left side can be rotated counterclockwise, i.e., the left end of the air inlet panel 14 on the left side is rotated downward to open the air inlets 112 on the left side; the right side air inlet panel 14 can be rotated clockwise, i.e., the right end of the right side air inlet panel 14 is rotated downward to open the right side air inlet 112.

The arrangement of the driving portion will be described below with reference to fig. 2 showing the arrangement of the two air inlets 112, i.e., the two air inlets 112 are symmetrical with respect to the axial plane of the air outlet 113. For other arrangement manners of the air outlet 113, the arrangement manner of the driving portion can be found below, and is not described herein again.

Fig. 3 is a perspective view of the panel 1 shown in fig. 1, and fig. 4 is an exploded view of the panel 1 shown in fig. 3. As shown in fig. 2 to 4, in order to make the outer wall of the panel 1 flat, the length of the outlet 113 in the Y direction is smaller than the length of the inlet 112 in the Y direction. The driving portion is provided between the front and/or rear end of the outlet 113 and the side wall of the base 11 so that the driving portion is closer to the middle of the air inlet panel 14 than the front and rear ends of the air inlet panel 14. In addition, a swing blade may be disposed in the air outlet 113, so that a user can adjust a flow direction of air flowing out of the air outlet.

When a set of driving parts is provided, the driving parts are disposed between the front end of the air outlet 113 and the front side wall of the base 11, or between the rear end of the air outlet 113 and the rear side wall of the base 11; when the driving parts are provided in two sets as mentioned below, the two sets of driving parts may be provided at the front and rear sides of the air outlet 113, respectively, as shown in fig. 3 and 4.

The fan 32 of the indoor unit may be a cross-flow fan 32 or a centrifugal fan 32. When the cross flow fan 32 is selected, in order to increase the intake of the cross flow fan 32, the cross flow fan 32 having a longer axial length is generally selected. Since the fan housing 31 disposed outside the cross flow fan 32 communicates with the air outlet 113 of the panel 1, the air outlet 113 of the panel 1 is long in the axial direction of the cross flow fan 32, that is, the front end and the rear end of the air outlet 113 are far apart. The air inlets 112 disposed at the left and right sides of the air outlet 113 are long. In order to prevent the two longitudinal ends (the front and rear ends of the air inlet plate 14) of the air inlet plate 14 for opening and closing the air inlet 112 from being incapable of rotating synchronously due to being too long, two sets of driving parts for driving the air inlet plate 14 to rotate may be provided, and the two sets of driving parts may be respectively provided at two sides of the air outlet 113 in the longitudinal direction, that is, the two sets of driving parts are respectively provided at the front end and the rear end of the air outlet 113. The driving part at the front end can drive the front end of the left air inlet plate 14 and the front end of the right air inlet plate 14 to synchronously rotate. The driving part at the rear end can drive the rear end of the left air inlet plate 14 and the rear end of the right air inlet plate 14 to synchronously rotate. The two sets of driving portions may share one driving source 23, or two driving sources 23 as in fig. 3 and 4 may be employed. When two drive sources 23 are used, the two drive sources 23 may be triggered by the same signal source to enable the two drive sources 23 to operate synchronously.

Fig. 5 is a partial schematic view of the drive plate 21 and link assembly 22 shown in fig. 4. As shown in fig. 5, the driving portion includes a driving plate 21, two sets of link assemblies 22, and a driving source 23. The driving plate 21 is located between the two air inlet plates 14 and is slidably disposed on the base 11. The driving plate 21 can slide on the base 11 in the vertical direction due to the vertical displacement of the air inlet plate 14. Two sets of link assemblies 22 are provided, each set of link assemblies 22 being disposed between the drive plate 21 and each of the intake plates 14. Since the two air inlets 112 are symmetrical with respect to the first imaginary plane, the two sets of link assemblies 22 are also arranged symmetrically with respect to the first imaginary plane. Two ends of each group of connecting rod assemblies 22 are respectively in transmission connection with the driving plate 21 and the corresponding air inlet plate 14. That is, in fig. 5, the two air inlets 112 are symmetrical with respect to the axial plane of the air outlet 113, the two air inlet plates 14 are symmetrical with respect to the axial plane of the air outlet 113, and the two sets of link assemblies 22 are also symmetrical with respect to the axial plane of the air outlet 113. The air inlet plate 14 on the left side is in transmission connection with the connecting rod assembly 22 on the left side, and the air inlet plate 14 on the right side is in transmission connection with the connecting rod assembly 22 on the right side. It should be noted that the above mentioned transmission connection can refer to a rotation connection, a sliding connection, or both.

According to the panel 1 provided by the utility model, the driving plate 21 and the two groups of connecting rod assemblies 22 which are symmetrically arranged are arranged between the two air inlet plates 14, and the driving plate 21 slides on the base 11 by operating the driving part, so that the two groups of connecting rod assemblies 22 connected with the driving plate 21 are synchronously driven, and further the two air inlet plates 14 respectively connected with the two groups of connecting rod assemblies 22 are synchronously rotated, so that the two air inlets 112 are synchronously opened or closed, one driving part can respectively drive the two air inlet plates 14, the weight of the panel 1 assembly is favorably reduced, and the energy consumption is favorably saved.

Fig. 5 is a schematic view of the driving part and the air inlet plate 14 at the front end of the panel 1, and as shown in fig. 4 and 5, a fixing seat 13 is provided between the front end of the air outlet 113 and the side wall of the base 11, and the fixing seat 13 may include a housing 131 for fixing the driving source 23, a fixing plate 132, and a rear cover 138. The fixing plate 132 and the driving plate 21 may be disposed in a receiving space surrounded by the housing 131 and the rear cover 138. The rear cover 138 may be provided with slide rails disposed in a vertical direction, in which the drive plate 21 may slide so as to define a sliding direction of the drive plate 21. The driving source 23 may be a motor connected to an external power source or an internal battery, and the motor includes a motor shaft.

The driving source 23 drives the driving plate 21 to slide on the fixing seat in the vertical direction in the following manner:

in one possible implementation, as shown in fig. 5, the motor shaft can pass through the housing 131 and a gear 24 is fixedly connected, i.e. the gear 24 can rotate with the rotation of the motor shaft. Fig. 6 is a schematic view of the drive plate 21 of fig. 4. in conjunction with fig. 4-6, the drive plate 21 may be provided with a rack 212 that engages the gear 24. The driving source 23 may rotate by driving the gear 24 to move the rack 212 up and down in a length direction thereof. The gear 24, the drive plate 21, and the fixing plate 132 are disposed in the housing space.

It should be noted that, when the two driving portions share one driving source 23 and the driving source 23 is a motor, two driving portions may be provided, and the two driving portions are respectively disposed at the front end and the rear end of the air outlet 113. That is, the drive plate 21 and the gear 24 may be provided in two numbers, respectively. Two gears 24 may be respectively disposed at the front and rear ends of the intake vent 112, and the rack 212 of each driving plate 21 is engaged with the gear 24. A motor shaft of the driving source 23 may be connected with a rotating shaft, a front end of which is connected with a gear 24 located at the front end, and a rear end of which is connected with the gear 24 located at the rear end.

In another possible implementation, a screw rod disposed in a vertical direction may be connected to the driving source 23. The screw rod can be arranged on the driving plate 21 and is in threaded connection with the driving plate 21. The driving source 23 rotates by driving the screw to realize the lifting of the driving plate.

The structure of the fixing seat and the link assembly will be described below by taking as an example the driving manner of the driving plate 21 shown in fig. 5, i.e., the manner of moving the driving plate 21 by the engagement of the gear 24 with the rack 212. The manner in which the screw is used to move the drive plate 21 can be seen below and will not be described in detail here.

Fig. 7 is a front view of the fixing plate 132 in fig. 5. As shown in fig. 4, 5 and 7, the fixing plate 132 is provided with a mounting hole 136, and the above-mentioned gear 24 is rotatable with respect to the mounting hole 136. The fixing plate 132 may be provided with mounting posts 134, and fasteners may pass through the housing 131 and be threadedly coupled with the mounting posts 134 to achieve fixation between the fixing plate 132 and the housing 131. The fixing plate 132 may have two first slide rails 133 symmetrically disposed thereon, and the two first slide rails 133 may be symmetrical with respect to an axial plane of the air outlet 113. As shown in fig. 6, the driving plate 21 is symmetrically provided with two second slide rails 211, and the two second slide rails 211 may be symmetrical with respect to an axial plane of the air outlet 113. Alternatively, the first slide rail 133 and the second slide rail 211 may both be slide grooves to facilitate processing.

In addition, fig. 8 is a front view of the drive plate 21 and the link assembly 22 shown in fig. 5, and fig. 9 is a rear view of the drive plate 21 and the link assembly 22 shown in fig. 5. As shown in fig. 5-9, each link assembly 22 includes a first link 221 and a first slider 222 hinged to a first end of the first link 221. The first slide rail 133 is opposite to the second slide rail 211, so that each first slide block 222 is slidably disposed in the corresponding first slide rail 133 and the second slide rail 211. The second end of each first connecting rod 221 is hinged with the corresponding air inlet plate 14. The middle portion of each first link 221 makes a circular motion with respect to the fixed plate 132.

In order to hide the driving portion, the driving portion may be disposed in a receiving space surrounded by the housing 3 and the base 11, and the driving plate 21 may be disposed above the air inlet plate 14 (the upper portion refers to an oblique upper portion). Each first slide rail 133 can be inclined downward toward the corresponding air inlet panel 14, and each second slide rail 211 can be inclined upward toward the corresponding air inlet panel 14. Specifically, in fig. 9, of the two first slide rails 133, the left end of the first slide rail 133 on the left side is inclined downward toward the air inlet panel 14 on the left side, and the right end of the first slide rail 133 on the right side is inclined downward toward the air inlet panel 14 on the right side. In fig. 8, of the two second slide rails 211, the left end of the second slide rail 211 positioned on the left side is inclined upward toward the left air inlet panel 14, and the right end of the second slide rail 211 positioned on the right side is inclined upward toward the right air inlet panel 14.

Fig. 10 is a simplified view of the air inlet panel 14 closing the air inlet 112 according to the embodiment of the present invention, and fig. 11 is a simplified view of the air inlet panel 14 opening the air inlet 112 according to the embodiment of the present invention, wherein fig. 10 and 11 are both views illustrating the rotation of the air inlet panel 14 on the left side. The movement of the left side air inlet panel 14 by the left side linkage assembly 22 will now be described with reference to fig. 9-11. When the air inlet panel 14 is in the position for closing the air inlet 112, i.e., in the horizontal position, one end of the first slider 222 is located at the top of the first slide rail 133. When the air inlet plate 14 moves from the position shown in fig. 10 to the position shown in fig. 11, the driving plate 21 moves downward relative to the fixing plate 132 under the action of the driving source 23, and the first slider 222 slides downward along the first slide rails 133 within the first slide rails 133. The first link 221 hinged with the first slider 222 has a tendency to move downward. Since the middle portion of the first link 221 makes a circular motion with respect to the fixed plate 132, the first link 221 positioned at the left side rotates counterclockwise, so that the air inlet panel 14 positioned at the left side hinged to the first link 221 rotates counterclockwise.

Fig. 12 is a schematic view of another connecting rod assembly 22 according to an embodiment of the present invention, and fig. 13 is a schematic view of another connecting rod assembly 22 according to an embodiment of the present invention. In order to realize the circular motion of the middle portion of the first link 221 with respect to the fixed plate 132, as shown in fig. 12, a rocking bar 26 may be disposed between the middle portion of the first link 221 and the fixed plate 132, one end of the rocking bar 26 may be hinged to the first link 221, and the other end of the rocking bar 26 may be hinged to the lower end of the fixed plate 132. The joint of the rocker 26 and the first link 221 can move circularly along with the movement of the driving plate 21. It should be noted that, in addition to the rocker 26, as shown in fig. 13, an arc-shaped slide way 137 may be disposed on the fixed plate 132, the middle portion of the first link 221 is connected with a third slide block 27, and the third slide block 27 can slide in the arc-shaped slide way 137, so as to realize that the middle portion of the first link 221 makes a circular motion relative to the fixed plate 132.

Optionally, at least a portion of the first link 221 is arc-shaped so as to improve the strength of the first link 221. Illustratively, in fig. 10 and 11, the first link 221 includes an arcuate segment hingedly connected to the first slider 222 and a linear segment hingedly connected to the air inlet panel 14, and the aforementioned rocker 26 may be hingedly connected to the junction of the arcuate segment and the linear segment.

It should be noted that the first link 221 positioned on the left side can be hinged to the right end of the air inlet panel 14 positioned on the left side, and the first link 221 positioned on the left side can also be hinged to the middle of the air inlet panel 14. When the first link 221 at the left side is hinged with the right end of the air inlet panel 14 at the left side, there is an advantage in that an area where the air inlet 112 can be opened is large. When the first connecting rod 221 positioned at the left side can also be hinged with the middle part of the air inlet plate 14, the advantage that the stress at the hinged part of the first connecting rod 221 and the air inlet plate 14 is small is provided.

In order to obtain a larger opening area of the intake vents 112 and to reduce the force applied to the hinge of the first link 221 with the air inlet panel 14, the first link 221 located on the left side may be hinged with the right end of the air inlet panel 14 located on the left side, as shown in fig. 9-11. The mounting seat 141 may be installed on the air inlet plate 14, and the mounting seat 141 may be provided with a third slide rail 142. The connecting rod assembly 22 further includes a second connecting rod 223, the second connecting rod 223 on the left side is hinged to the middle portion of the first connecting rod 221 on the left side, and the second connecting rod 223 is further hinged to a second sliding block 224, and the second sliding block 224 is slidably disposed on the third sliding rail 142. In this way, the second link 223 can share the stress of the hinge of the link assembly 22 and the air inlet panel 14, and the openable area of the air inlet 112 is not affected.

In addition, as shown in fig. 9, a first end of the second link 223 may be hinged to the fixed plate 132, a middle portion of the second link 223 may be hinged to a middle portion of the first link 221, and a second end of the second link 223 may be hinged to the second slider 224. That is, the above-mentioned rocker 26 may have the first end of the second link 223 serving as the first end. In order to simplify the connecting-rod assembly 22. The left and right sides of the lower end of the fixed plate 132 in fig. 7 may be respectively provided with a hinge hole 135 for the second link 223 at the left and right sides to hinge with the fixed plate 132.

Optionally, in order to improve the strength of the second link 223, at least a portion of the second link 223 is arc-shaped. The second link 223 may include a first linear section hinged to the fixed panel 132, a second linear section hinged to the air inlet panel 14, and an arc-shaped section disposed between the first and second linear sections. The middle of the second link 223 in fig. 9 is where the first straight line segment connects with the arc segment.

Alternatively, for convenience of processing, the third slide rail 142 may also be a slide slot, and the second slide block 224 can slide in the slide slot.
