Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The following relationship exists between the air supply distance and the air outlet volume of the raise-boring machine in the prior art: when the air supply distance is far, the attenuation of the air outlet air quantity is larger, and when the air supply distance is near, the attenuation of the air outlet air quantity is smaller. Aiming at the problem that the air output is greatly attenuated when the air supply distance of the courtyard machine is far, the related parameters (the diameter and the rotating speed of the fan) of the fan are simply selected and increased to ensure the air output in the prior art, so that the whole size of the courtyard machine needs to be increased or the cost is increased. However, after the applicant researches the air outlet flow of the raise-frame machine and analyzes the air outlet flow through simulation experimental data, the technical scheme for increasing the relevant parameters of the fan is actually more advantageous, and is unfavorable for further development of industry, but the parameters related to the size of the air outlet and the size of the air channel in the raise-frame machine, which are ignored and ignored in the art, are improved points for effectively improving the matching degree of the air supply distance and the air outlet volume of the raise-frame machine.
Therefore, in order to ensure that the air supply distance and the air outlet volume of the raise-frame machine in the refrigeration mode reach the optimal degree as far as possible, the application provides the raise-frame machine with the refrigeration mode as shown in fig. 1 and 2, comprising a main body frame 1, wherein an air outlet duct 2 is arranged in the main body frame 1, and the air outlet duct 2 is provided with a first end 21 and a second end 22 along the air flow direction; the air outlet component 3 is arranged on the main body frame 1, when the courtyard machine is in a refrigerating mode, the air outlet component 3 and the main body frame 1 have a height difference, an air outlet 10 is formed between the air outlet component 3 and the main body frame 1, and the air outlet 10 is communicated with the second end 22 of the air outlet duct 2; the ratio of the height h1 of the air outlet 10 to the width h2 of the first end 21 of the air outlet duct 2 is in the range of 1/3.ltoreq.h1/h2.ltoreq.3/5.
The main body frame 1 is a main bearing structure of the courtyard machine, and when the courtyard machine is installed, the main body frame 1 is used for being installed on a ceiling, and other structures can be directly or indirectly installed on the main body frame 1 and fixed on the ceiling through the main body frame 1. The height h1 of the air outlet 10 is the height between the edge of the lowest point of the air outlet channel formed by the main body frame and the edge of the outermost side of the air outlet component in the direction that the air outlet component and the main body frame form a height difference. The courtyard machine has the interior machine part of installing in the ceiling, and main body frame 1 is connected with interior machine, and air-out subassembly 3 is connected on main body frame 1, and interior machine has interior machine air exit, and the first end 21 of the air-out wind channel 2 of main body frame 1 communicates with interior machine air exit, and the air flow route: the air is blown out from the air return opening, the evaporator, the air outlet of the internal fan, the first end 21 of the air outlet air duct 2, the second end 22 of the air outlet air duct 2 and the air outlet.
When the courtyard machine works, air flows from the first end 21 to the second end 22 of the air outlet air duct and finally is discharged out of the courtyard machine through the air outlet 10, and when the courtyard machine is designed, in order to ensure the balance between the air supply distance and the air outlet air quantity of the courtyard machine, a designer can determine specific parameters of the courtyard machine according to the range of the ratio of the height h1 of the air outlet to the width of the first end 21 of the air outlet air duct 2, so as to ensure that the air outlet effect of the produced courtyard machine reaches the preset requirement.
Taking 3 pieces of experimental data as an example, in the scheme, h2 is 60mm, the numerical value of h1 is adjusted to carry out simulation, and the simulation result is as follows:
| h1 | h1/h2 | air volume (m) 3 /h) | Distance of air supply |
| 15 | 0.25 | 667 | 3.3m |
| 20 | 0.33 | 834 | 3.5m |
| 28 | 0.47 | 1005 | 3.5m |
| 36 | 0.6 | 1112 | 2m |
| 45 | 0.75 | 1112 | 1.2m |
From the experimental results, when h1/h2 is 0.47, the air quantity attenuation is small, the air supply distance is far enough, and the air quantity attenuation is optimal (figure 3); when h1/h2 is increased to 0.6, the air quantity reaches the maximum, but the air supply distance is obviously shortened (figure 4); when h1/h2 is continuously increased to 0.75, the air supply distance is seriously shortened and is not acceptable (FIG. 5); when h1/h2 is reduced to 0.33, the air quantity is about 75% of the maximum value (FIG. 6); the air volume decay was severe and unacceptable as h1/h2 continued to decrease to 0.25 (FIG. 7).
The air outlet component 3 is arranged on the main body frame 1 in a lifting manner, the air outlet component 3 is provided with a working position which is lowered to a set height to form the height difference, and when the air outlet component 3 is positioned at the working position, the ratio of the height h1 of the air outlet 10 to the width h2 of the first end 21 of the air outlet air duct 2 is in a range of 1/3-3 h1/h 2-3/5. At this time, the height h1 of the air outlet 10 is the height between the edge of the lowest point of the air outlet duct formed by the main body frame and the edge of the outermost side of the air outlet assembly in the lifting direction of the air outlet assembly 3.
The air-out subassembly 3 includes aviation baffle 4 and air-out frame, and the air-out frame sets up on main body frame 1, and aviation baffle 4 rotatable setting is on the air-out frame, and when air-out subassembly 3 is in the working position, and aviation baffle 4 can adjust the height of air outlet 10. At this time, the height of the air outlet is the height between the edge of the lowest point of the air outlet channel formed by the main body frame and the edge of the outermost side of the air deflector in the lifting direction of the air outlet assembly.
The air deflector 4 is provided with a first position for enabling the height h1 of the air outlet 10 to reach the minimum value, the ratio range of the minimum value of the height h1 of the air outlet 10 to the width of the first end 21 of the air outlet air duct 2 is 1/3-1/h 2-3/5, and the air outlet effect of the courtyard machine is ensured by determining the rotation range of the air deflector through the ratio range.
The air deflector 4 can guide the air outlet at the air outlet 10, when the raise-boring machine is in a refrigerating mode, in order to achieve the effect of waterfall type refrigeration, the angle range of the included angle a between the plane of the air deflector 4 and the horizontal plane is-10 degrees, and when a=0 degrees, the plane of the air deflector 4 is parallel to the horizontal plane. At this time, the air outlet at the air outlet 10 can flow along the wall (attached to the ceiling) as far as possible under the limitation of the air deflector 4, and then the waterfall refrigeration effect is formed by virtue of the downward flowing characteristic of cold air.
Preferably, when the raise boring machine is in the refrigerating mode, the angle range of the included angle a is 10 degrees or more and a is more than 0 degrees, and when a is more than 0 degrees, the air deflector 4 is inclined upwards relative to the horizontal plane, namely, the air deflector 4 is always in a state of being inclined upwards relative to the horizontal plane, so that the wall attaching effect of the air outlet 10 is increased, and the air supply distance and the refrigerating effect of the raise boring machine are increased.
The air outlet assembly is provided with a closing position matched with the main body frame 1 to close the air outlet 10, the air deflector 4 is provided with a first edge 41 and a second edge 42, when the air outlet assembly 3 is in the closing position, the first edge 41 is in sealing arrangement with the corresponding position of the main body frame 1, and the second edge 42 is in sealing arrangement with the corresponding edge of the air outlet frame. Through the corresponding seal of the first edge 41 and the main body frame 1 and the corresponding seal of the second edge 42 and the air outlet frame, when the air outlet assembly is in the closed position, the air deflector 4 can seal the corresponding position of the air outlet 10, so that the performance of the courtyard machine is prevented from being influenced by dust and other impurities entering the courtyard machine from the position of the air outlet 10.
When the air outlet assembly 3 is in the closed position, the air outlet frame and the air deflector 4 are sealed together in a matched manner with the main body frame 1. At this moment, the air-out subassembly is laminated with the main part frame, and the opening on the main part frame is covered up by the air-out subassembly completely to make the courtyard machine have good outward appearance effect.
The second edge 42 is provided with a first step structure, and the air outlet frame is provided with a second step structure matched with the first step structure, so that when the air outlet assembly 3 is in the closed position, the first step structure and the second step structure are in sealing fit. The first step structure and the second step structure can ensure that the sealing between the air deflector 4 and the air outlet frame is reliable, and meanwhile, the structural interference between the air deflector 4 and the air outlet assembly 3 can not be generated in the rotating process of the air deflector 4, so that the structural reliability of the air outlet assembly 3 is affected.
The first step structure is provided with a sealing member, and when the air outlet assembly 3 is in the closed position, the sealing member is arranged between the first step structure and the second step structure. That is, the sealing piece moves together with the air deflector, and when the air deflector and the air outlet frame are sealed relatively, the sealing piece can seal a gap between the air deflector and the air outlet frame, so that the sealing effect between the air deflector and the air outlet frame is improved.
The courtyard machine further comprises a rotating mechanism, the rotating mechanism is arranged on the air outlet frame, and the air deflector 4 is arranged on the rotating mechanism.
The rotating mechanism comprises a rotating arm 5, one end of the rotating arm 5 is hinged to the air outlet frame, and the other end of the rotating arm 5 is arranged on the air deflector 4.

The rotating mechanism further comprises a driving piece, the driving piece is arranged on the air outlet frame, and the driving piece directly or indirectly drives the rotating arm 5 to rotate. Wherein one end of the rotating arm 5 is arranged on the driving piece, and the air deflector 4 is arranged on the other end of the rotating arm 5, when the rotating arm 5 rotates with the end part arranged on the driving piece, the air deflector 4 can move together with the end part of the rotating arm 5, so that the rotation of the air deflector 4 is realized, wherein the driving piece can be a stepping motor.
The courtyard machine further comprises a lifting mechanism, the lifting mechanism is arranged on the main body frame 1, and the air outlet assembly 3 is arranged on the lifting mechanism. The air outlet assembly 3 can extend out of or retract into the main body frame 1 by a lifting mechanism, so that the air outlet assembly 3 can freely move between a working position and a closing position.
The air outlet assembly 3 comprises an air outlet frame, an air outlet is formed between the air outlet frame and the main body frame, and the air outlet frame is independently lifted.

As shown in fig. 8 and 9, another embodiment of the raise-boring machine is provided, at least one second air outlet 13 is provided on the air outlet assembly 3, and the second air outlet 13 is communicated with the second end 22 of the air outlet duct 2. The second air outlet 13 is arranged, so that the raise boring machine can meet the requirements of obliquely downward air outlet and even vertically downward air outlet. And the air outlet mode of the courtyard machine can be increased through the cooperation of the air outlet 10 and the second air outlet 13, so that the air outlet effect of the courtyard machine, the accuracy of temperature adjustment and the speed of adjustment are increased.
When the air outlet assembly 3 forms the air outlet 10 by descending with the main body frame 1, a space is formed between the air outlet assembly 3 and the main body frame 1, the space forms an air supply duct 14, one end of the air supply duct 14 is communicated with the air outlet duct 2, and the other end of the air supply duct 14 forms the air outlet 10. The air flow in the air outlet air duct 2 is blown out from the air outlet 10 after being guided by the air supply air duct 14, and the air flow vertically downward in the air outlet air duct 2 is guided into the direction which is approximately horizontally far away from the courtyard machine and even is upwards inclined relative to the horizontal plane by the air supply air duct 14, so that the horizontal air outlet to the courtyard machine is realized.
In the prior art, all the patio machines are provided with air outlets on the surface facing the ground for air outlet, in order to change the air outlet direction, air deflectors are arranged at the air outlets for guiding, but on the installation plane of the patio machine, the projection of the air deflectors is not overlapped with the projection of the panel of the patio machine, so that the guiding effect of the air deflectors on the air flow is poor, and finally the air supply distance of the patio machine is reduced. When the projection of the air outlet component 3 is overlapped with the projection part of the frame 15, the air outlet component is substantially prolonged relative to the prior art, so that the horizontal blowing effect of the courtyard machine is good, the air supply distance is increased, when the courtyard machine opens the air outlet 10, the air outlet component 3 is gradually far away from the main body frame 1 to form the air supply air duct 14, at the moment, the corresponding part of the air outlet component 3 forms the lower side surface of the air supply air duct 14, and when the air flow flows through the air supply air duct 14, the air flow flows along the horizontal direction and is blown out even along the upward inclined direction under the flow guiding effect of the lower side surface of the air supply air duct, so that the air supply distance of the courtyard machine is increased, and the effect of horizontal air outlet is realized.
As another embodiment, the projection of the air outlet assembly 3 and the projection of the frame 15 completely coincide, in this case, the air outlet assembly can be further prolonged compared with the case where the projection of the air outlet assembly 3 and the projection of the frame 15 partially coincide, so that the horizontal blowing effect of the raise-lift unit is better, and the air supply distance is further increased. Meanwhile, when the courtyard machine is in a stop state, the air outlet assembly 3 is attached to the main body frame 1, the corresponding part of the air outlet assembly 3 is attached to the frame 15, and when people observe the courtyard machine from the ground, only the air outlet assembly 3 can be seen, but the main body frame 1 cannot be seen, so that the attractiveness of the courtyard machine is effectively improved.
As another embodiment, the projection of the air outlet assembly 3 exceeds the projection of the frame 15, in this case, the air outlet assembly can be further prolonged compared with the case that the projection of the air outlet assembly 3 completely coincides with the projection of the frame 15, so as to further increase the horizontal blowing effect and the blowing distance of the raise-boring machine.
Preferably, the projection of the air outlet assembly 3 exceeds the projection of the main body frame 1, so that the air outlet assembly 3 effectively increases the air guide size relative to the prior art, and the purpose of increasing the air supply distance of the courtyard machine is achieved.
The courtyard machine further comprises an air deflector 4, the air deflector 4 is rotatably arranged at the second air outlet 13, and the air deflector 4 can close or open the second air outlet 13. When the second air outlet 13 needs to be opened, the air deflector 4 gradually rotates, so that the second air outlet 13 is communicated with the air outlet air duct 2, the air flow in the air outlet air duct 2 can be blown out by the second air outlet 13, and the air deflector 4 can adjust the air outlet direction and/or the air outlet air quantity of the second air outlet 13 according to actual needs by adjusting the inclination angle of the air deflector; when the second air outlet 13 needs to be closed, the air deflector 4 is reset to be in sealing fit with the air outlet assembly 3, so that the second air outlet 13 is closed, and at the moment, the air flow in the air outlet air duct 2 can be blown out from the air outlet 10 only under the common guiding action of the air outlet assembly 3 and the air deflector 4.
The foregoing examples illustrate only a few embodiments of the application and are described in detail herein without thereby limiting the scope of the application. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
