For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The ceiling machines in the prior art are all designed for the simultaneous cooling and heating needs in the room, so that their air outlets need to be exposed to the outside to achieve the purpose of downward air discharge in the heating mode for rapid heating. The user can directly see the air sweeping plate of the air outlet from the bottom of the ceiling machine. When the ceiling machine is cooling, even if the air sweeping plate at the air outlet guides the airflow horizontally, there will still be some cold air flowing directly downward from the bottom of the air sweeping plate, which is equivalent to the cold air still being able to blow directly to the user, and the problem of cold wind blowing people cannot be avoided. In order to enable the ceiling machine to blow horizontally in the cooling mode so that the airflow flows against the wall, the technical solution adopted is to set the air outlet component as a liftable structure, and the main frame is fixedly set on the circumferential outer side of the air outlet component. When the ceiling machine is working, the air outlet component drops a certain height and forms a height difference with the main frame. The air outlet component and the main frame set on the outside of the air outlet component form an air outlet. The fan blows air from the inside of the ceiling machine through the air outlet, and uses the air guide plate at the air outlet to guide the airflow. In particular, when the air conditioner is in cooling mode, it is necessary to make the air outlet as parallel to the horizontal plane as possible to increase the air supply distance, thereby achieving waterfall cooling and improving user comfort. However, the existing ceiling machine is equipped with a lifting structure with a heavy panel weight, and after frequent use of the lifting function, the wear of the movement mechanism or the increase in the matching gap will cause the ceiling machine to produce condensation, noise, and the risk of reduced reliability of the movement mechanism, which seriously affects the user experience. To this end, the present application provides a method such as Figures 1 to 9 The ceiling machine shown includes: a main frame 1, in which an air outlet duct 11 is formed; a panel assembly, which is arranged on the main frame 1, and an air outlet 12 is arranged on the panel assembly, and the air outlet duct 11 is connected to the outside of the ceiling machine through the air outlet 12; a guide plate 2, which is movably arranged on the main frame 1 or on the panel assembly, and the guide plate 2 has a first state of being located at the lower side of the air outlet 12 so that the ceiling machine can discharge air horizontally, and the guide plate 2 also has a second state of avoiding the lower side of the air outlet 12 so that the ceiling machine can discharge air vertically. By adjusting the state of the guide plate 2, the horizontal and vertical air outlets of the ceiling machine can be adjusted, which effectively avoids the problem of wear of the moving mechanism and increased matching clearance caused by the need to set up a complex lifting structure in the prior art, improves the structural reliability of the ceiling machine, avoids the problems of condensation and noise in the ceiling machine, improves the user experience, and can also reduce the production difficulty and production cost of the ceiling machine, thereby improving the cost performance of the ceiling machine.

[0043] The panel assembly includes a return air grille 3, which is arranged on the main frame 1, and the guide plate 2 is movably arranged on the return air grille 3, and when the guide plate 2 is in the first state, the guide plate 2 protrudes from the return air grille 3, at which time the guide plate 2 can be moved to the bottom of the air outlet 12, and the airflow passing through the air outlet 12 can only flow horizontally under the restriction of the guide plate 2, thereby achieving the purpose of horizontal air outlet of the ceiling machine. When the guide plate 2 is in the second state, the guide plate 2 retracts into the return air grille 3, at which time the guide plate 2 cannot block the bottom of the air outlet 12, and the airflow can be blown downward or obliquely downward through the air outlet 12, thereby achieving the purpose of vertical air outlet of the ceiling machine. Moreover, when the guide plate 2 is in the first state, the guide plate 2 can form a visible surface of the ceiling machine together with the return air grille 3, further shielding the installation area of ​​the ceiling machine, especially shielding the air outlet 12, avoiding the internal structure of the ceiling machine directly through the air outlet 12, thereby improving the aesthetics of the ceiling machine.

[0044] An air inlet area is formed on the return air grille 3. When the guide plate 2 is in the second state, the guide plate 2 covers part of the air inlet area or the guide plate 2 is located outside the air inlet area, that is, the guide plate 2 will not block the air inlet area or can leave part of the air inlet area for air intake, thereby ensuring that the air intake of the ceiling machine is reliable and the ceiling machine can work normally.

[0045] The panel assembly also includes an air outlet frame 4, and there is a second spacing between the guide plate 2 and the main frame 1. The air outlet frame 4 is arranged within the second spacing, and the air outlet 12 is formed on the air outlet frame 4. The second spacing allows the air outlet 12 to be arranged on the side wall of the air outlet frame 4 for horizontal air outlet. At the same time, a horizontal air supply duct with a certain size can be formed between the guide plate 2 and the main frame 1. The air outlet of the air outlet duct 11 can first flow horizontally through this horizontal air supply duct, and then flow to the air outlet 12 for air outlet after the horizontal flow, and finally achieve the purpose of horizontal air outlet of the ceiling machine.

[0046] The air outlet frame 4 includes an air outlet side plate 5, on which the air outlet 12 is arranged, wherein the upper edge of the air outlet side plate 5 is sealed with the main frame 11, and the lower edge is sealed with the return air grille 3, and the upper edge of the air outlet side plate 5 is inclined relative to the lower edge in a manner away from the middle of the ceiling machine, and when the guide plate 2 is in the first state, the projection of the air outlet 12 on the plane where the guide plate 2 is located is completely located on the guide plate 2. At this time, the airflow blowing out of the air outlet 12 that flows obliquely downward can all hit the guide plate 2, and then can only flow horizontally under the guiding effect of the guide plate 2, thereby ensuring the reliability of the horizontal air outlet of the ceiling machine.

[0047] The ceiling machine also includes an air guide plate 6, which is movably disposed at the air outlet 12, and the air guide plate 6 can adjust the airflow direction of the air outlet 12. The air guide plate 6 is used to guide the airflow of the air outlet 12, thereby improving the air outlet effect of the ceiling machine. Since the ceiling machine has an air outlet 12, dust and some small animals will enter the interior of the ceiling machine through the air outlet 12, causing the possibility of damage to the ceiling machine. For this reason, the ceiling machine can also use the air guide plate 6 to open and close the air outlet 12. When the ceiling machine is in use, the air guide plate 6 is switched to the open state to ensure the air outlet effect. When the ceiling machine is not in use, the air guide plate 6 closes the air outlet 1212, thereby preventing dust and some small animals from entering the interior of the ceiling machine through the air outlet 12, thereby ensuring the reliability of the ceiling machine.

[0048] When the guide plate 2 is in the first state, the guide plate 2 will guide the airflow of the air outlet 12 horizontally, that is, the ceiling machine needs to discharge air horizontally at this time, so the guide plate 6 and the guide plate 2 are parallel to each other. At this time, the guide plate 6 will not hinder the airflow, and can also guide part of the airflow of the air outlet 12, thereby improving the horizontal air outlet effect of the ceiling machine and improving the heat exchange efficiency of the ceiling machine.

[0049] When the guide plate 2 is in the second state, the guide plate 2 is retracted and will not affect the airflow direction of the air outlet 12. In order to further improve the tendency of the airflow at the air outlet 12 to flow vertically downward, the air guide plate 6 is parallel to the vertical direction. The air guide plate 6 can guide the airflow at the air outlet 12 to flow vertically downward, especially when the ceiling machine is heating, the vertically downward flowing airflow can be used to achieve the purpose of rapid heating.

[0050] The ceiling machine has a wind sweeping mode. When the ceiling machine is in the wind sweeping mode, the guide plate 2 is in the second state, and the guide plate 2 will not hinder the airflow of the air outlet 12. The air guide plate 6 swings up and down to guide the airflow of the air outlet 12 in different directions to achieve the wind sweeping effect.

[0051] The patio machine has a cooling mode and a heating mode;

[0052] When the ceiling machine is in the cooling mode, the guide plate 2 is in the first state, and the guide plate 2 can guide the cold air from the air outlet 12 to flow horizontally, thereby increasing the flow distance of the cold air in the horizontal direction, thereby enabling the ceiling machine to achieve the purpose of waterfall cooling;

[0053] When the ceiling machine is in the heating mode, the guide plate 2 is in the second state. At this time, the guide plate 2 is separated from the bottom of the air outlet 12, and the hot air from the air outlet 12 can flow downward or diagonally downward, thereby increasing the rate at which the hot air reaches the ground, thereby enabling the ceiling machine to achieve the purpose of rapid heating.

[0054] The ceiling machine has at least two side surfaces, each of which is provided with an air outlet 12, and a guide plate 2 is provided at each air outlet 12. The ceiling machine is provided with air in different directions by using multiple side surfaces, so as to further improve the heat exchange efficiency of the ceiling machine, and each air outlet 12 is provided with a guide plate 2, each guide plate 2 can guide the air out of the corresponding air outlet 12, so as to ensure that each air outlet 12 can discharge air horizontally, thereby ensuring the air outlet effect of the ceiling machine.

[0055] The skylight machine also includes a driving mechanism 7, which is arranged on the main frame 1 or the panel assembly. The guide plate 2 is connected to the driving mechanism 7, and the driving mechanism 7 can drive the guide plate 2 to switch between the first state and the second state. The driving mechanism 7 is set to drive the guide plate 2 to move, so that reliable adjustment of the state of the guide plate 2 is achieved. The guide plate 2 can be directly adjusted through the electrical signal obtained by the driving mechanism 7, thereby improving the user experience.

[0056] As an embodiment, the driving mechanism 7 includes a motor and a telescopic bracket, the telescopic bracket is connected to the motor, and the motor can adjust the length of the telescopic bracket, and the guide plate 2 is connected to the telescopic bracket. The motor can obtain an electrical signal to work, and when the motor is working, the rotation of the motor can drive the telescopic bracket to adjust the length, thereby driving the guide plate 2 set on the telescopic bracket to move, so as to achieve the purpose of adjusting the state of the guide plate 2.

[0057] As another embodiment, the driving mechanism 7 includes a motor and a rack, a driving gear is provided on the output shaft of the motor, the driving gear and the rack are meshed with each other, and the guide plate 2 is connected to the rack. The motor can obtain an electrical signal to work, and when the motor is working, the rotation of the motor can drive the driving gear to rotate, and the driving gear can drive the rack to move, thereby driving the guide plate 2 connected to the rack to move, so as to achieve the purpose of adjusting the state of the guide plate 2.

[0058] As another embodiment, the driving mechanism 7 includes a motor and a connecting rod transmission mechanism, one end of the connecting rod transmission mechanism is hinged on the output shaft of the motor, and the other end of the connecting rod transmission mechanism is connected to the guide plate 2. The motor can obtain electrical signals to work. When the motor is working, the rotation of the motor can be transmitted to the guide plate 2 through the connecting rod transmission mechanism, and because the connecting rod transmission mechanism can convert the rotation of the motor into a linear movement of the guide plate 2, the purpose of adjusting the state of the guide plate 2 is achieved. Fig. 9 As shown, the number of motors in the figure is 1, the connecting rod transmission mechanisms correspond to the guide plates 2 one by one, and all the connecting rod transmission mechanisms are connected to the motors. The rotation of the motors can synchronously drive all the guide plates 2 to move.

[0059] In order to ensure the reliable movement of the guide plate 2, a limiting groove 13 is provided on the main frame 1 or the panel assembly, and at least part of the guide plate 2 is arranged in the limiting groove 13. The limiting groove 13 is used to limit the movement of the guide plate 2 to ensure that the guide plate 2 can only move along the set direction, thereby ensuring the reliability of the ceiling machine.

[0060] Due to the setting of the guide plate 2, the cooling airflow of the ceiling machine will flow horizontally along the guide plate 2. At this time, the cooling airflow will flow in the direction away from the ceiling machine, resulting in a lack of cold air in the space near the ceiling machine. For this reason, an air hole 21 is set on the guide plate 2. When the airflow flows through the guide plate 2, part of the airflow can pass through the guide plate 2 through the air hole 21 and flow downward. Since the flow area of ​​the air hole 21 is small, the airflow will slow down when flowing through the air hole 21 and form a breeze around the ceiling machine. The wind speed of this breeze is small, which is equivalent to a feeling of no wind or a feeling of breeze. On the basis of being able to cool the surrounding space of the ceiling machine, it will not cause the problem of high wind speed blowing directly on the human body and affecting the user experience. Therefore, on the basis of ensuring horizontal air supply, the cooling effect of the ceiling machine on the space where the ceiling machine is located can be improved.

[0061] An air conditioning unit comprises the above-mentioned patio unit.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
