Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses an air conditioner, as shown in figure 1, including heat exchanger and the electrically controlled device that the interval set up to and cover the air conditioner panel 100 on heat exchanger and electrically controlled device. An air inlet grill is provided at one side of the air-conditioning panel 100. The air conditioner panel 100 and the air inlet grille both belong to one part of an air conditioner external shell, the air conditioner panel 100 covers the heat exchanger and the electric control device, so that a relatively sealed structure is formed inside the air conditioner, when the air conditioner operates, air flow enters the air conditioner from the air inlet grille, then the air flow and the heat exchanger perform heat exchange, and the air conditioner performs heating or cooling. In order to increase the intake air volume, an air inlet 110 is opened and closed in the air conditioner panel 100. The openable and closable means that the air inlet 110 can be controlled to be opened or closed. When the air inlet 110 is in an open state, a part of air flow enters from the air inlet grille, and the other part of air flow enters from the air inlet 110, so that the air inlet amount is increased.

The air inlet 110 is located at the side of the heat exchanger and away from the side of the electric control device. That is, when the air current enters from the air inlet 110, the air current is directly blown to the position of the heat exchanger, and the air current is not blown to the electric control device, so that the air inlet can be kept smooth. Because a part of the front surface of the air conditioner panel 100 covers the heat exchanger, and another part covers the electric control device, if the air inlet 110 is located at a position facing the electric control device, and air flows directly blow on the electric control device when air is introduced from the air inlet 110, the electric control device will obstruct the air inlet, and the air inlet efficiency is affected to a certain extent. And through the above arrangement, the air inlet efficiency is improved to a certain extent.

Referring to fig. 1 to 5, an opening and closing device 200 is disposed at the air inlet 110, and when in use, the air inlet 110 can be opened or closed by the opening and closing device 200. The opening and closing device 200 includes an air inlet deflector 210 and a driving motor 220, the air inlet deflector 210 is rotatably connected to the air conditioner panel 100, and when the driving motor 220 works, the air inlet deflector 210 can be driven to rotate, so as to control the opening or closing of the air inlet 110. Wherein, the opening action here refers to: the air inlet deflector 210 is rotated at an angle to allow air flow from the air inlet 110. And shut down means: when the air inlet deflector 210 closes the air inlet 110, the air flow is substantially blocked by the air inlet deflector 210, and most of the air flow cannot enter from the air inlet 110, or the air flow is completely blocked by the air inlet deflector 210, and all the air flow cannot enter from the air inlet 110.

The air inlet deflector 210 is connected to the output shaft of the driving motor 220 through a connecting shaft 230, and the air inlet deflector 210 is detachably connected to the air conditioner panel 100. The detachable connection here means that the intake air guide plate 210 can be rotated by the driving motor 220 when in use, and the intake air guide plate 210 can be separated from the air conditioner panel 100 by manual operation when not in use. When the air inlet deflector 210 is disassembled, the air inlet deflector 210 can be cleaned and maintained independently. Meanwhile, maintenance can be performed on the internal local structure of the air conditioner, such as the internal heat exchanger, through the air inlet 110.

The air inlet deflector 210 is fixed with a driving plate 212 on one side surface close to the heat exchanger, and the air inlet deflector 210 is rotatably connected with the air conditioner panel 100 through the driving plate 212. The length direction of the driving plate 212 is parallel to the rotation axis of the air inlet guide plate 210. The two ends of the driving plate 212 are bent toward one side of the air inlet guide plate 210, and the whole driving plate 212 is in a "U" shape, and may be in other shapes, such as an "H" shape. The driving plate 212 comprises a linkage plate 212b at the middle part and an installation part 212c with two ends forming a vertical linkage plate 212b, wherein the installation part 212c is fixedly connected with the air inlet guide plate 210, the fixed connection can be integrally formed and connected, or fixed connection by using bolts and screws or other fixed connection modes, as long as the fixed connection of the two is realized. The connecting shaft 230 is connected to one of the mounting plates, thereby controlling the entire driving plate 212 to rotate to drive the intake air guide plate 210. The driving board 212 may have the above structure, or may be directly fixed to the air inlet guide plate 210 by using only one linkage board 212b, or fixed to the air inlet guide plate 210 by using only two mounting portions 212 c. The above structure has the advantage that when the driving motor 220 drives the driving plate 212 to rotate, the two ends of the air inlet guide plate 210 in the length direction can rotate synchronously.

The rotation shaft 213 is fixed to one of the mounting portions 212c, and may be integrally formed with the mounting portion 212c, or the rotation shaft 213 and the mounting portion 212c may be connected by using a bolt so that the rotation shaft 213 and the mounting portion 212c do not rotate relative to each other. A boss 130 is fixed to the air conditioner panel 100, and the boss 130 is located on one side surface of the air conditioner panel 100 close to the inside of the air conditioner. The boss 130 is formed with a positioning hole 131, the rotation shaft 213 is inserted into the positioning hole 131, and the rotation shaft 213 is rotatable with respect to the positioning hole 131, that is, a gap is formed between the rotation shaft 213 and an inner wall of the positioning hole 131, and the rotation shaft 213 is rotatable, and the rotation shaft 213 is disengaged from the positioning hole 131 when a force is applied in a length direction of the rotation shaft 213.

At the end remote from the rotation axis 213, the driving plate 212 is detachably connected to the connection axis 230, wherein the detachable connection here is: when the air conditioner is used, the connecting shaft 230 can drive the driving plate 212 to rotate, when the air conditioner is not rotated, external force is applied along the axial direction of the connecting shaft 230, the connecting shaft 230 and the driving plate 212 can be separated, and after separation, the rotating shaft 213 can be separated from the positioning hole 131, so that the whole air inlet air deflector 210 is separated from the air conditioner panel 100.

An axis hole 212a is opened on the mounting part 212c of the driving plate 212 far from the end of the rotating shaft 213, an inserting shaft 231 is integrally formed at one end of the connecting shaft 230, the inserting shaft 231 can be inserted into the axis hole 212a, and the inserting shaft 231 and the axis hole 212a are detachably connected. When the plug shaft 231 rotates, the driving plate 212 can be driven to rotate synchronously. One of the implementation modes is as follows: the cross section of the insertion shaft 231 is circular, and the insertion shaft 231 and the shaft position hole 212a are in interference fit, where the interference fit means that static friction force exists between the insertion shaft 231 and the shaft position hole 212a, and when the insertion shaft 231 rotates, relative rotation does not occur between the shaft position hole 212a and the insertion shaft 231 under the action of the static friction force. When an external force is applied in the length direction of the insertion shaft 231, the shaft hole 212a and the insertion shaft 231 may be separated. In a better mode, the section of the insertion shaft 231 is polygonal, and the section of the axis hole 212a is also polygonal, so that when the insertion shaft 231 is inserted into the axis hole 212a, the insertion shaft 231 cannot rotate relative to the axis hole 212a due to the polygonal section, and the driving plate 212 can be better driven to rotate. Similarly, the insertion shaft 231 is in interference fit with the shaft hole 212a, where the interference fit means that there is static friction between the insertion shaft 231 and the shaft hole 212a, and in the axial direction, when no external force is applied, the position between the shaft hole 212a and the insertion shaft 231 is relatively fixed, and when the external force is applied, the two can be separated.

The above-mentioned center line of the axis hole 212a and the axis of the rotating shaft 213 coincide with each other, and the coincidence means that the center line of the axis hole 212a and the axis of the rotating shaft 213 are aligned on the same line. If the two are not collinear, i.e., the two ends of the drive plate 212 rotate along different axes of rotation, the drive plate 212 cannot rotate.

The connecting shaft 230 is close to one end of the driving motor 220 along the axis direction, namely, the end far away from the inserting shaft 231 along the axis direction is provided with a shaft connecting hole 232, the output shaft of the driving motor 220 is detachably connected with the shaft connecting hole 232, the detachable connection here means that when the connecting shaft is in normal operation, the output shaft of the driving motor 220 is positioned in the shaft connecting hole 232 and can drive the connecting shaft 230 to rotate, when the connecting shaft does not work, external force is applied, and the output shaft of the driving motor 220 can be separated from the shaft connecting hole 232.

The shaft connection hole 232 and the section of the output shaft of the driving motor 220 may be polygonal, or a rib may be formed in the shaft connection hole 232 toward one side of the center in the radial direction, and a groove may be formed on the output shaft of the driving motor 220 in the axial direction, the groove being engaged with the rib, so that when the output shaft of the driving motor 220 rotates, the connecting shaft 230 may be driven to rotate.

In addition to the above, the output shaft and the shaft connecting hole 232 may be connected by forming a key groove and using a key, so as to prevent the output shaft and the shaft connecting hole 232 from rotating relatively.

In the use, in order to guarantee the stability of output shaft and hub connection hole 232, interference fit between output shaft and the hub connection hole 232, there is static friction between output shaft and the hub connection hole 232 promptly, and in the use, relative movement can not appear in the two, and when applying certain external force, the output shaft can overcome static friction along the axis direction and remove.

The output shaft and the shaft connecting hole 232 can also be fixed along the direction perpendicular to the phase axis by using a pin shaft, so that relative rotation between the output shaft and the shaft connecting hole 232 cannot occur, and meanwhile, the position movement cannot occur along the axis direction.

There is a space between the shaft connecting hole 232 and the shaft end of the output shaft, and the space between the two should satisfy the condition that the insertion shaft 231 can be disengaged from the positioning hole 212a while the rotation shaft 213 is disengaged from the positioning hole 131 when the connection shaft 230 is moved to the output shaft side by the external force. At this time, the driving plate 212 can be detached from the air-conditioning panel 100.

The driving plate 212 is located on a side of the air inlet deflector 210 relatively far away from the air inlet grille of the air conditioner. When driving motor 220 drives drive plate 212 and rotates, driving motor 220 rotates same angle, and rotation that the air inlet aviation baffle 210 is parallel to the axis of rotation one side, and rotation that can be more angle is to keeping away from air intake 110 one side, compares in setting up drive plate 212 in air inlet aviation baffle 210 middle part position, and air intake 110 department opens the area bigger, and the air current is great relatively during the air inlet, and air inlet efficiency is higher.

The air-conditioning panel 100 is provided with a mounting base 140, the mounting base 140 is located on the side of the electric control device, and the driving motor 220 is fixed to the mounting base 140. The mounting base 140 is provided with a mounting hole for mounting the driving motor 220, and when mounting, the driving motor 220 is first placed in the mounting hole, and then the driving motor 220 is fixed to the mounting hole by using bolts.

The driving motor 220 is arranged on one side close to the electric control device, wiring can be more convenient after installation, and a circuit of the driving motor 220 can be directly connected with a PCB (printed circuit board) on the electric control device to supply power to the driving motor 220. When the air conditioner is started, the driving motor 220 is controlled to rotate for a certain angle and then stops, the air inlet guide plate 210 opens the air inlet 110 and keeps the state, and the air inlet 110 assists the air inlet grille in ventilation. When the air conditioner is turned off, the driving motor 220 rotates in a reverse direction by a certain angle, and the air inlet guide plate 210 closes the air inlet 110.

Referring to fig. 6 and 7, taking the air inlet duct 210 as an example for closing the air inlet 110, a first step 211 is integrally formed at one side of the air inlet duct 210, a second step 120 is integrally formed at one side of the air inlet 110, the length directions of the first step 211 and the second step 120 are respectively parallel to the rotation axis direction of the air inlet duct 210, and a group of the first step 211 and the second step 120 is respectively arranged at one side close to the line of the connecting shaft 230 or one side far away from the connecting shaft 230. When the air inlet guide plate 210 rotates to close the air inlet 110, the first step 211 and the second step 120 are buckled with each other. When the air inlet 110 is closed by the air inlet deflector 210 after the first step 211 and the second step 120 are provided, the gap between the air inlet deflector 210 and the air inlet 110 is blocked by the first step 211 and the second step 120, and the black seam does not occur, so that the process requirement of the air inlet deflector 210 is reduced to a certain extent. The processing is easier, and the air conditioner panel 100 is more beautiful because there is no black line on the air conditioner panel 100 and at the air inlet 110.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
