Description

Technical Field

[0001] The present invention relates to the technical field of air duct machines, and in particular to an air duct machine. Background Art

[0002] The duct air conditioner has a return air inlet and an air outlet. After the duct air conditioner is disassembled, a high-pressure water gun can be inserted from the return air inlet to clean the evaporator in the shell. When the current duct air conditioner uses a high-pressure water gun to clean the evaporator from the return air side, water will pass through the fins and rush out of the air outlet of the fuselage and splash onto the user's ceiling panel, thereby causing environmental pollution around the ceiling panel. Summary of the invention

[0003] The problem solved by the invention is that when cleaning the evaporator inside the existing duct machine, water sprayed from the high-pressure water gun will splash from the air outlet onto the ceiling board used, causing environmental pollution of the ceiling board.

[0004] In order to solve the above-mentioned problem, the present invention provides an air duct dryer, comprising a shielding assembly, which is arranged at the air outlet of the air duct dryer, and the shielding assembly has a shielding position for completely closing the air outlet and an open position for opening the air outlet. When the shielding assembly is in the shielding position, the air outlet is completely closed to prevent cleaning water from splashing out of the air duct dryer from the air outlet during the cleaning process.

[0005] Optionally, the air duct machine further includes a driving mechanism, which is connected to the shielding assembly and is used to drive the shielding assembly to move so as to close or open the air outlet.

[0006] Thus, when the duct machine is in a normal working mode, the driving mechanism drives the shielding assembly to move to open the air outlet, and the air circulating inside the duct machine is discharged normally from the air outlet; when the duct machine is in a cleaning mode, the driving mechanism drives the shielding assembly to move to close the air outlet, thereby effectively preventing water from splashing from the air outlet to the outside of the duct machine during the cleaning operation of the evaporator, thereby avoiding environmental pollution outside the duct machine. Optionally, the shielding assembly includes a rotating shaft and a flexible cloth driven by the rotating shaft, wherein the flexible cloth includes a foldable canvas baffle.

[0007] Therefore, when the air duct machine is in a normal working mode, the rotating shaft is driven to rotate manually or by a driving mechanism to retract the flexible cloth to open the air outlet; when the air duct machine is in a cleaning mode, the rotating shaft is driven to rotate manually or by a driving mechanism to unfold the flexible cloth to close the air outlet.

[0008] Optionally, the shielding assembly includes an air guide plate, and the driving mechanism is connected to the air guide plate and is used to drive the air guide plate to rotate so as to close or open the air outlet.

[0009] That is, when the duct air conditioner is in normal working mode, the driving mechanism drives the air guide plate to rotate downward to expose the air outlet. At this time, the air outlet is in an open state, and the air circulating inside the duct air conditioner is discharged normally from the air outlet. When the evaporator in the duct air conditioner is cleaned, the driving mechanism drives the air guide plate to rotate upward until the air guide plate blocks the air outlet, effectively preventing water from splashing out of the air outlet.

[0010] Optionally, the duct machine further comprises a first side plate and a second side plate for fixing the evaporator, the driving mechanism is arranged on the first side plate, and a guide groove is provided on the second side plate for facilitating the rotation of the air guide plate.

[0011] Therefore, the driving mechanism is arranged on the first side plate, and a guide groove is provided on the second side plate corresponding to the first side plate, so as to guide and rotate the air guide plate.

[0012] Optionally, the driving mechanism includes a driving motor, a connecting piece and a support rod, the working end of the driving motor is connected to one end of the connecting piece, the other end of the connecting piece is vertically connected to the end of the support rod, the air guide plate is arranged on the support rod, and the other end of the support rod slides in the guide groove. The driving motor drives the connecting piece to drive the support rod to rotate, so that the support rod slides in the guide groove.

[0013] The drive motor thereby drives the connecting plate to rotate, thereby driving the support rod and the air guide plate to rotate upward or downward, so that the air guide plate switches between the blocking position and the open air outlet position, and the guide groove on the second side panel provides supporting force for the support rod to prevent the support rod from deforming.

[0014] Optionally, when the shielding component closes the air outlet, the lower edge of the shielding component is lower than the lowest end of the air outlet, and the distance between the two is not less than 3 mm;

[0015] Thus, after closing the air outlet, the lower edge of the shielding component is lower than the lowest end of the air outlet by more than 3 mm, and the shielding component effectively completely shields the air outlet to prevent water from splashing from the air outlet. Optionally, when the shielding component opens the air outlet, the lower edge of the shielding component is higher than the lowest end of the air outlet, and the distance between the two is not less than 3 mm.

[0016] Therefore, after the air outlet is opened, the lower edge position of the shielding assembly is higher than the lowest end position of the air outlet by more than or equal to 3 mm, so that when the air duct machine works normally, the air circulating inside the air duct machine can be discharged normally from the air outlet.

[0017] Optionally, the shielding assembly includes a shutter, and the driving mechanism is connected to the shutter driving the shutter, whereby, when the duct air conditioner is working normally, the driving mechanism drives the shutter to rotate open, thereby opening the air outlet; when the duct air conditioner is in a cleaning mode, the driving mechanism drives the shutter to rotate closed, thereby closing the air outlet.

[0018] Optionally, the venetian blinds include a frame, a connecting plate, an active window panel and a driven window panel, the active window panel and the driven window panel are both rotatably arranged in the frame, and the driving mechanism is drivingly connected to the active window panel; the connecting plate connects the active window panel and the driven window panel in series; thus, when the cleaning mode is performed, the driving motor works to drive the active window panel to rotate and close, and through the connecting action of the connecting plate, it synchronously drives a plurality of driven window panels to rotate and close, thereby effectively controlling the active window panel and the driven window panel of the venetian blinds to rotate and close synchronously, thereby closing the air outlet; when the air duct machine is in the working mode, the driving motor works to drive the active window panel to rotate and open, and through the connecting action of the connecting plate, it synchronously drives a plurality of driven window panels to rotate and open, thereby effectively controlling the active window panel and the driven window panel of the venetian blinds to rotate and open synchronously, thereby opening the air outlet.

[0019] Optionally, the shutter further includes an active sleeve, a first vertical plate, multiple pairs of second vertical plates and multiple pairs of driven sleeves, the active sleeve is arranged at the end of the active window plate through the first vertical plate, and the multiple pairs of driven sleeves are respectively installed at the ends of multiple driven window plates through multiple pairs of the second vertical plates.

[0020] Therefore, the active sleeve plays a connecting role between the active window panel and the frame, so that the active window panel can be set in the frame through the active sleeve, and the driven sleeve plays a connecting role between the driven window panel and the frame, so that the driven window panel can be set in the frame through the driven sleeve.

[0021] Optionally, the shielding assembly further includes an active shaft sleeve and a driven shaft sleeve, and the active shaft sleeve is adaptably connected to the active sleeve to install the active window panel in the frame, and the driven shaft sleeve is adaptably connected to the driven sleeve to install the driven window panel in the frame.

[0022] Therefore, after the working end of the driving mechanism passes through the active shaft sleeve and extends into the active sleeve, the driving mechanism drives the active sleeve to drive the active window plate to rotate, that is, the active shaft sleeve is used to provide the driving mechanism with the transmission power for the rotation of the active window plate; the driven shaft sleeve is adaptively connected to the driven sleeve, thereby providing rotational support force for the driven window plate.

[0023] Optionally, the shutter further includes a first clamp and multiple pairs of second clamps, the first clamp is vertically arranged on the first vertical plate, and the multiple pairs of second clamps are respectively and vertically arranged on multiple pairs of the second vertical plates; and the connecting plate is provided with clamping grooves matching the first clamp and the second clamp.

[0024] Therefore, the connecting plate is connected with the first clamping rib and the second clamping rib through the clamping groove. When the driving mechanism works to drive the active window panel to rotate, the connecting action of the connecting plate enables the active window panel and multiple driven window panels to be linked, thereby realizing synchronous rotation to close or open, so as to realize the closing or opening of the air outlet.

DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] In the drawings of the embodiments of the present invention, a coordinate system XYZ is provided, wherein the positive direction of the X axis represents the left, the negative direction of the X axis represents the right, the positive direction of the Y axis represents the back, the negative direction of the Y axis represents the front, the positive direction of the Z axis represents the top, and the negative direction of the Z axis represents the bottom.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; the term "adaptation" should be understood in a broad sense, for example, it can be a socket connection, or it can be a plug connection, that is, the two can achieve relative motion or synchronous motion; the drive connection should be understood in a broad sense, for example, it can be one component driving another component to rotate, or it can be one component driving another component to rotate. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the description of this specification, "first" and "second" do not constitute a limitation on specific quantities, but are only for the convenience of distinction and description.

[0046] Related technology, a duct machine, including a partition, which divides the interior of the duct machine into a heat exchange chamber and a return air chamber, an evaporator 2 is installed on the left and right plates inside the heat exchange chamber, a water receiving tray 5 is arranged at the bottom of the evaporator 2 in the heat exchange chamber, an air outlet 1 is opened at a position corresponding to the bending part of the evaporator 2 on the front side of the duct machine, and a volute is arranged in the return air chamber to generate circulating air; a high-pressure water gun penetrates from one side of the return air chamber to clean the evaporator 2, and water will pass through the fins of the evaporator 2 and splash out from the air outlet 1 of the duct machine.

[0047] To this end, the present invention designs a duct air conditioner, wherein a shielding component 4 is provided at the air outlet 1 of the front side panel of the duct air conditioner to prevent water from splashing out of the air outlet 1; when the duct air conditioner is working normally, the shielding component 4 moves to the air outlet or open position of the air outlet 1 to open the air outlet 1; when the evaporator 2 of the duct air conditioner is cleaned, the shielding component 4 moves to the front side of the air outlet 1 to completely shield the entire air outlet 1, so that when the evaporator 2 is cleaned with a high-pressure water gun, the water is blocked by the shielding component 4 and flows downstream to be caught by the water receiving tray 5, thereby preventing the water from rushing out of the body of the duct air conditioner and polluting the ceiling; wherein, the shielding component 4 can be moved by manual operation or by electric control, and the air outlet 1 can be closed or opened.

[0048] It should be noted that the shielding component does not include the air guide plate installed at the air outlet of the duct machine in the prior art; that is, in the prior art, an air guide plate is installed at the air outlet of the duct machine, but the air guide plate does not completely close the air outlet, that is, there is a gap between the air guide plate and the air outlet of the duct machine. When cleaning the evaporator of the duct machine, the water sprayed by the high-pressure water gun will pass through the evaporator and splash out from the gap; therefore, when it is necessary to clean the evaporator in the duct machine, in order to truly and effectively prevent the water from the high-pressure water gun from passing through the evaporator and splashing out from the air outlet, the shielding component needs to completely close the air outlet, and the complete closure means that when cleaning the evaporator, the shielding component can completely block the splashing water and prevent it from spraying out from the air outlet, but the shielding component can maintain a certain gap with the air outlet; the advantage of such a setting is that during the cleaning process, the shielding component can completely block the water from splashing out of the duct machine from the air outlet, thereby avoiding environmental pollution.

[0049] like Figure 1 and Figure 2As shown, when the shielding component 4 closes the air outlet 1, the lower edge position of the shielding component 4 is lower than the lowest end of the air outlet 1, and the distance between the two is not less than 3 mm. At this time, the shielding component 4 effectively and completely blocks the air outlet 1 to prevent water from splashing out of the air outlet 1, and because the lower edge of the shielding component 4 is lower than the lowest position of the air outlet 1 by more than 3 mm, it prevents water from blowing toward the shielding component 4 when cleaning the evaporator 2, causing the lower part of the shielding component 4 to rotate or tilt outward, thereby failing to block water.

[0050] In one embodiment of the present invention, when the shielding component 4 opens the air outlet 1, the lower edge position of the shielding component 4 is higher than the lowest end of the air outlet 1, and the distance between the two is not less than 3 mm, so that when the air duct machine is working normally, the wind inside the air duct machine is discharged from the air outlet 1; when the air duct machine is working normally, the lower edge position of the shielding component 4 is higher than the lowest end of the air outlet 1 by more than 3 mm, thereby not affecting the wind inside the air duct machine from blowing outward.

[0051] In one embodiment of the present invention, the duct machine also includes a driving mechanism 3, which is electrically controlled, that is, controlled by a motor assembly; the driving mechanism 3 is drivingly connected to the shielding component 4, and is used to drive the shielding component 4 to move so as to close or open the air outlet 1.

[0052] In one embodiment of the present invention, Figures 3 to 5 As shown, the shielding assembly 4 includes a rotating shaft and a flexible cloth 40 driven by the rotating shaft, and one end of the flexible cloth 40 is fixed on the rotating shaft.

[0053] It should be noted that by controlling the rotation of the rotating shaft, the flexible cloth is driven to rotate, fold or unfold, thereby opening or closing the air outlet. The flexible cloth 40 includes but is not limited to a baffle made of foldable canvas, and can also be a foldable flexible baffle made of other materials, which will not be described in detail here.

[0054] In this embodiment, the folding or unfolding of the flexible cloth can be achieved by manual control; that is, the two ends of the rotating shaft are installed on the left plate and the right plate through bearing seats, and a rotating handle is provided after one end of the rotating shaft extends out of the left plate or the right plate, and the rotating handle is manually operated to drive the rotating shaft to rotate, thereby realizing the rotation, folding or unfolding of the flexible cloth, so as to realize the opening or closing of the air outlet.

[0055] In this embodiment, the folding or unfolding of the flexible cloth can be automatically controlled by a driving mechanism; that is, the driving mechanism 3 includes a driving motor 30, which is drivingly connected to one end of the rotating shaft. When the cleaning mode is performed, the driving motor 30 drives the rotating shaft along the attached Figure 3 The flexible cloth 40 is rotated in the direction of A to unfold and lower the flexible cloth 40 until the entire air outlet 1 is covered; when the cleaning is completed, before the air duct machine enters the working mode, the driving motor 30 drives the rotating shaft along the attached Figure 4 The flexible cloth 40 is retracted in the direction of B until the entire air outlet 1 is exposed; the fixed end of the driving motor 30 is mounted on the left side panel or the right side panel of the evaporator 2. For example, when the fixed end of the driving motor 30 is mounted on the left side panel, the working end of the driving motor 30 passes through the left side panel and is drivingly connected to one end of the rotating shaft. The other end of the rotating shaft can be mounted on the right side panel through a bearing seat. The bearing seat provides support for the rotating shaft and the flexible cloth 40, wherein the fixed end of the bearing seat is mounted on the right side panel, and the other end of the rotating shaft is fixedly embedded in the center position of the bearing seat.

[0056] In one embodiment of the present invention, Figures 6 to 10 As shown, different from the above embodiment, the shielding assembly 4 includes an air guide plate 41, and the driving mechanism 3 is drivingly connected to the air guide plate 41 for driving the air guide plate 41 to rotate so as to close or open the air outlet 1.

[0057] It should be noted that the duct machine also includes a first side panel 61 and a second side panel 62 for fixing the evaporator 2, wherein the first side panel 61 is the left side panel of the evaporator 2, and the second side panel 62 is the right side panel of the evaporator 2, and the driving mechanism 3 includes but is not limited to being arranged on the left side panel, that is, when the driving mechanism 3 is arranged on the first side panel 61, a guide groove 63 is provided on the second side panel 62 for facilitating the rotation of the air guide plate 41; that is, the driving mechanism 3 drives the air guide plate 41 to rotate when it works, that is, the air guide plate 41 rotates and switches between the shielding position and the open position to realize closing or opening the air outlet 1.

[0058] It should be noted that the driving mechanism 3 includes a driving motor 30, a connecting member 31 and a support rod 32, the fixed end of the driving motor 30 is installed on the first side panel 61, the working end of the driving motor 30 is connected to one end of the connecting member 31, the other end of the connecting member 31 is vertically connected to the end of the support rod 32, the air guide plate 41 is arranged on the support rod 32, and the other end of the support rod 32 slides in the guide groove 63; wherein, the driving motor 30 is not limited to being installed on the first side panel 61, that is, the fixed end of the driving motor 30 can be installed on the right side panel of the evaporator 2, and at this time, the left side panel of the evaporator 2 is provided with a guide groove 63, and the other end of the support rod slides in the guide groove 63 on the left side panel.

Since the air guide plate 41 is fixedly arranged on the support rod 32, the air guide plate 41 rotates together with the support rod 32 until the air guide plate 41 is between the evaporator 2 and the water receiving tray 5, and the entire air outlet 1 is exposed. Since the air guide plate 41 is arranged in an arc structure, the wind blown to the water receiving tray 5 through the evaporator 2 in the working state of the air duct machine can be effectively guided out to change the wind field structure in the heat exchange chamber. The guide slot 63 on the second side plate 62 provides a rotation support force for the support rod 32 and the air guide plate 41, that is, the guide slot 63 is a sliding track for the support rod 32, which effectively prevents the support rod 32 from deforming.
