Description

Technical Field

[0001] The utility model relates to the technical field of air processing equipment, in particular to a patio machine and an air conditioning unit. Background Art

[0002] The ceiling machines in the prior art are all designed for the simultaneous cooling and heating needs in the indoor environment, so that the air outlets thereof need to be exposed to the outside in order to achieve the purpose of downward air discharge for rapid heating in the heating mode. The user can directly see the wind sweeping plate of the air outlet from the bottom of the ceiling machine. When the ceiling machine is cooling, even if the wind sweeping plate at the air outlet guides the airflow horizontally, some cold air will still flow directly downward from under the wind sweeping plate, which means that the cold air can still blow directly to the user, and the problem of cold wind blowing on people cannot be avoided.

[0003] In order to enable the ceiling machine to blow horizontally in the cooling mode so that the airflow flows along the wall, the technical solution adopted in the prior art is to set the air outlet component to 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 to 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. Especially when the air conditioner is in the 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.

[0004] However, for the cooling-only air-conditioning markets in Southeast Asia, the Middle East, and Latin America, there is no demand for heating, only cooling operation is required. The solution of lifting and lowering the air outlet leads to a complex air-conditioning structure. The air outlet lifting function involves a heavy panel weight. Frequent lifting and lowering for a long time will cause certain wear and tear, resulting in an increase in the matching gap, causing condensation, noise, and reliability life risks. In addition, the cost is high, which seriously affects the user experience. Utility Model Content

[0041] The ceiling machines in the prior art are all designed for the simultaneous cooling and heating needs in the room, so that the 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 addition, 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 in the prior art is to set the air outlet component to 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. Especially 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, for the single-cooling air conditioner market in Southeast Asia, the Middle East, and Latin America, there is no demand for heating, only cooling operation is required. The solution of lifting the air outlet leads to a complex air conditioner structure. The air outlet lifting function involves a heavy panel. Frequent lifting for a long time will cause certain wear and tear, resulting in an increase in the matching gap, condensation, noise, and reliability life risks, and the cost is high, which seriously affects the user experience. To this end, the present application provides a method such as Figures 1 to 5The 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 arranged on the main frame 1 or on the panel assembly, and the guide plate 2 is located at the lower side of the air outlet 12, and the guide plate 2 can guide the airflow of the air outlet 12 so that the ceiling machine can exhaust air horizontally. The guide plate 2 is set to guide the airflow of the air outlet 12 horizontally, so that the guide plate 2 can block the air outlet 12 and the airflow of the air outlet 12, that is, it can prevent the user from directly observing the air outlet 12 and improve the aesthetics of the ceiling machine, and can ensure that the air outlet of the ceiling machine can only flow horizontally, thereby overcoming the problem that even if the air guide plate at the air outlet 12 in the prior art guides the air horizontally, part of the air flows downward and causes cold wind to blow people. At the same time, the ceiling machine is a single-cooling air conditioner, which does not need to heat. Therefore, the guide plate 2 can be directly fixed below the air outlet 12 for horizontal air outlet cooling, avoiding the use of the lifting structure in the prior art, thereby reducing the structural complexity of the ceiling machine, effectively avoiding the noise and condensation problems generated by the moving mechanism in the prior art, and improving the service life of the ceiling machine. At the same time, the user cannot directly observe the air outlet 12, and the air outlet 12 is hidden, thereby improving the user experience.

[0042] The panel assembly includes a return air grille 3, the return air grille 3 is arranged on the main frame 1, and the guide plate 2 is arranged on the return air grille 3. At this time, the guide plate 2 can form the 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, improving the aesthetics of the ceiling machine, and because the guide plate 2 is arranged on the return air grille 3, the guide plate 2 can be arranged along the shape of the return air grille 3, so that the visible surface of the ceiling machine is an overall planar structure, further improving the aesthetics, and the guide plate 2 and the return air grille 3 are also basically in the same plane (preferably a horizontal plane), which is convenient for processing the guide plate 2 and the return air grille 3, and reduces the production difficulty of the ceiling machine.

[0043] As an embodiment, the edge of the return air grille 3 extends away from the center direction of the return air grille 3 to form the guide plate 2. That is, the size of the return air grille 3 is increased to form the guide plate 2, which can facilitate the processing of the guide plate 2 and ensure the connection and sealing effect between the guide plate 2 and the return air grille 3, avoiding air leakage from the connection gap between the guide plate 2 and the return air grille 3. The airflow sent out of the air outlet duct 11 cannot contact the indoor gas or return air through the connection gap when it is about to flow to the air outlet 12, so that the airflow will not produce condensation due to heat exchange, and will not produce noise due to flowing through the connection gap, thereby avoiding the problems of condensation and noise, and the guide plate 2 in the present application does not need to be moved by a motion mechanism, so that the noise generated during the movement of the motion mechanism can be reduced, and the user experience of the ceiling machine is improved.

[0044] Since the ceiling machine needs to suck the indoor air into the main frame 1 through the return air grille 3 for processing, the return air grille 3 is arranged at the return air port 31 of the ceiling machine, and an air inlet area is formed on the return air grille 3 to allow the indoor air to flow into the main frame 1 through the return air port 31, and the air outlet of the ceiling machine needs to be guided by the guide plate 2. In order to avoid interference between the air outlet and return air of the ceiling machine, the minimum spacing d between the air inlet area and the guide plate 2 has a numerical range of d≥5mm. This minimum spacing d is used to further increase the distance between the return air and the air outlet of the ceiling machine, avoiding the problem of air outlet backflow in the ceiling machine, and this minimum spacing d can also provide an installation position for the structure (such as a partition, etc.) used to separate the return air and the air outlet inside the ceiling machine, so that the ceiling machine can smoothly take in and out air, thereby ensuring the reliable operation of the ceiling machine. Preferably, d is 10mm.

[0045] The panel assembly also includes an air outlet frame 6, and there is a second spacing between the guide plate 2 and the main frame 1. The air outlet frame 6 is arranged within the second spacing, and the air outlet 12 is formed on the air outlet frame 6. The second spacing allows the air outlet 12 to be arranged on the side wall of the air outlet frame 6 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 from the air outlet duct can first flow horizontally through the horizontal air supply duct, and then flow to the air outlet 12 for air outlet after the horizontal flow, finally achieving the purpose of horizontal air outlet of the ceiling machine.

[0046] In order to ensure the aesthetics of the ceiling machine, the guide plate 2 and the return air grille 3 are arranged in the same plane, and the surface of the ceiling machine observed by the user is a flat surface, which can effectively improve the aesthetics of the ceiling machine and improve the user experience. To this end, a return air port 31 is also formed on the air outlet frame 6, and the return air grille 3 is arranged at the return air port 31, and there is also a second distance between the return air grille 3 and the main frame 1. The return air grille 3 needs to deliver the indoor gas into the main frame 1. In order to avoid the return air flowing through the return air grille 3 and the air outlet 12 delivered by the main frame 1 from interfering with each other, the air outlet frame 6 also has a partition 4. The partition 4 is arranged between the return air port 31 and the air outlet duct 11 to ensure that there is no interference between the air inlet and the air outlet of the ceiling machine, thereby ensuring the working reliability of the ceiling machine. Figure 1 As shown in the figure, an air inlet channel is formed in the middle of the ceiling machine, and an air outlet channel 11 is formed on the outer peripheral side of the air inlet channel. At this time, a partition plate 4 is arranged between the air inlet channel and the air outlet channel 11 to separate the air inlet channel and the air outlet channel 11, thereby realizing the separation of the air inlet and air outlet of the ceiling machine.

[0047] Preferably, the numerical range of the second spacing h is h≥10mm. When h<10mm, the distance between the guide plate 2 and the main frame 1 is too small, and the flow area of ​​the air duct formed for horizontal air supply is small, resulting in an increase in wind resistance between the air outlet duct 11 and the air outlet 12, which affects the air outlet effect of the ceiling machine. Only when h≥10mm can the second spacing be prevented from generating resistance to the airflow discharged from the air outlet duct 11, thereby ensuring reliable air outlet of the ceiling machine.

[0048] The air outlet frame 6 includes an air outlet side plate 7, and the air outlet 12 is arranged on the air outlet side plate 7, wherein the upper edge of the air outlet side plate 7 is sealed with the main frame 1, and the lower edge is sealed with the guide plate 2 or with the connection position of the guide plate 2 and the return air grille 3, and the plane where the air outlet side plate 7 is located has an angle with the vertical plane;

[0049] When the angle is greater than 0°, the upper edge of the air outlet side plate 7 is inclined relative to the lower edge in a manner away from the middle of the ceiling machine, and the air outlet direction of the air outlet 12 will also flow obliquely downward as the air outlet side plate 7 is inclined. In order to ensure that the ceiling machine can have reliable horizontal air outlet, the relationship between the width a of the projection of the air outlet 12 on the plane where the guide plate 2 is located and the width L of the guide plate 2 is L≥a. At this time, the obliquely downward airflow blown out of the air outlet 12 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. When L<a, there will be some airflows at the air outlet 12 that cannot hit the guide plate 2. This part of the airflow will still maintain the ability to flow diagonally downward, causing the ceiling machine to still have air outlets flowing diagonally downward, and the horizontal air outlet effect of the ceiling machine cannot be guaranteed, especially for some air outlets 12 that are farther away from the guide plate 2. The airflow will flow to the front of the guide plate 2 and continue to flow diagonally downward. Moreover, since this part of the airflow is in the upper layer of the airflow at the air outlet 12, the ability of this part of the airflow to flow diagonally downward will also affect the airflow at the lower layer, which will also flow diagonally downward under the influence of this part of the airflow, causing the ceiling machine to be unable to have reliable horizontal air outlet. At this time, the user can still observe the part of the air outlet 12 that is not blocked by the guide plate 2 under the ceiling machine, affecting the aesthetics of the ceiling machine. Preferably, L=a. On the basis of ensuring that the guide plate 2 can reliably guide the airflow, the size of the guide plate 2 is reduced as much as possible to reduce the space occupied by the ceiling machine, reduce the strength requirement of the guide plate 2, and reduce the production cost. In addition, the guide plate 2 can also properly cover the air outlet 12 to prevent the user from directly observing the air outlet 12 from the bottom of the ceiling machine, thereby improving the aesthetics of the ceiling machine. Figure 1 As shown in the figure, the air outlet side plates 7 are distributed in a ring shape, and the upper edge of each air outlet side plate 7 is inclined away from the middle of the ceiling machine, so that the shape surrounded by the air outlet side plates 7 at this time is a trumpet shape with the opening upward. At this time, the airflow blown out by the air outlet 12 on each air outlet side plate 7 can directly hit the guide plate 2 and flow horizontally. On the basis of realizing multi-directional air outlet of the ceiling machine, the horizontal air outlet of the ceiling machine is guaranteed to be reliable.

[0050] When the angle is equal to 0°, the air outlet direction of the air outlet 12 is horizontal, and the numerical range of the width L of the guide plate 2 is L>0; at this time, the width L of the guide plate 2 does not need to be too large, and it only needs to carry the lower airflow of the air blown out of the air outlet 12 to a certain extent to ensure the horizontal air outlet effect of the ceiling machine. At the same time, the guide plate 2 can also block the air outlet 12 to prevent users from directly observing the air outlet 12 from the bottom of the ceiling machine, thereby improving the aesthetics of the ceiling machine.

[0051] The ceiling machine has at least two side surfaces, and each side surface is provided with an air outlet 12. The ceiling machine is used to discharge air horizontally in different directions by using multiple side surfaces, further improving 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 outlet of the corresponding air outlet 12, ensuring that each air outlet 12 can discharge air horizontally, thereby ensuring the horizontal air outlet effect of the ceiling machine.

[0052] like Figure 1 As shown, air inlet is provided in the middle of the bottom surface of the ceiling machine, air outlets 12 are arranged on the four sides for air outlet, return air grille 3 is arranged in the middle of the bottom surface of the ceiling machine, and a guide plate 2 is arranged on each of the four side walls of the ceiling machine, so that each guide plate 2 is located below the corresponding air outlet 12, thereby ensuring that the ceiling machine can discharge air horizontally reliably on the basis of discharging air to all directions, thereby improving the air outlet effect of the ceiling machine.

[0053] The ends of two adjacent flow guide plates 2 are connected to each other. At this time, there is no gap or spacing between the two adjacent flow guide plates 2, and the user can see the overall planar structure, which further improves the appearance of the ceiling machine. Figure 1 As shown, four guide plates 2 are arranged on the ceiling machine, and the return air grille 3 is located in the middle of the air outlet frame 6. The four guide plates 2 are connected in sequence, and the guide plates 2 and the return air grille 3 are arranged on the same plane. At this time, the surface of the ceiling machine seen by the user is a flat plate structure with the return air grille 3, which is aesthetically pleasing and provides a good user experience.

[0054] The width L of the guide plate 2 is obtained by the following formula:

[0055]

[0056] Among them, V is the design wind speed of the air outlet 12 (that is, the wind speed at the air outlet 12 when the ceiling machine is discharging the maximum air volume); H is the maximum distance between the guide plate 2 and the air outlet 12; g is the acceleration of gravity. After blowing out of the air outlet 12, it moves downward in a horizontal parabolic motion, which is equivalent to the airflow blown out of the air outlet 12 undergoing horizontal motion and free falling motion, blowing a horizontal distance x=ν*t, and the free fall height y=0.5*g*t2. Since the maximum distance between the guide plate 2 and the air outlet 12 (the distance between the guide plate 2 and the top of the air outlet 12) is H, if it can achieve the wind-guiding effect, it is equivalent to the wind that has to at least fall on the guide plate 2 to achieve the purpose of guiding the wind. Then it can be calculated that Then, within the time t, the wind blown out of the air outlet 12 will also flow in the horizontal direction, so the width of the guide plate 2 needs to be at least greater than the flow distance of the airflow in the horizontal direction, that is, L ≥ ν * t, and Therefore, in order to ensure that the guide plate 2 reliably guides the airflow of the air outlet 12, it can be concluded that the design requirement for the width L of the guide plate 2 is:

[0057] The numerical range of the maximum spacing H between the guide plate 2 and the air outlet 12 is 10mm≤H≤80mm. By limiting the numerical value of the maximum spacing H, it is ensured that the width of the guide plate 2 can be within a reasonable range, and it is also ensured that the size of the air outlet 12 meets the air outlet requirements of the ceiling machine. When H is less than 10mm, the size of the air outlet 12 is too small, and the air volume of the ceiling machine cannot meet the demand. When H is greater than 80mm, the width of the guide plate 2 is too large, causing the size of the ceiling machine to increase and affecting its space occupancy. At the same time, an overly large guide plate 2 will also reduce the appearance of the ceiling machine. Only when H is within the range of 10mm to 80mm can the width of the guide plate 2 be within an appropriate range while ensuring that the air volume of the ceiling machine meets the requirements, thereby reducing the occupied space of the ceiling machine and improving the aesthetics of the ceiling machine.

[0058] 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.

[0059] Since the skylight machine has an air outlet 12, dust and some small animals may enter the interior of the skylight machine through the air outlet 12, which may cause damage to the skylight machine. For this reason, the skylight machine also includes an air guide plate 5, which is movably arranged at the air outlet 12, and the air guide plate 5 has a closed state for closing the air outlet 12 and an open state for opening the air outlet 12. The air guide plate 5 is used to open and close the air outlet 12. When the skylight machine is in use, the air guide plate 5 is switched to the open state to ensure the air outlet effect. When the skylight machine is not in use, the air guide plate 5 closes the air outlet 12, thereby preventing dust and some small animals from entering the interior of the skylight machine through the air outlet 12, thereby ensuring the reliability of the skylight machine.

[0060] Specifically, the air guide plate 5 is rotatably disposed at the air outlet 12. When the air guide plate 5 is in the closed state, the edge of the air guide plate 5 is sealed with the edge of the air outlet 12, thereby achieving reliable closure of the air outlet 12 by the air guide plate 5; when the air guide plate 5 is in the open state, the air guide plate 5 and the guide plate 2 are parallel to each other. At this time, the air guide plate 5 will not hinder the airflow, and can also guide part of the airflow of the air outlet 12, thereby further improving the horizontal air outlet effect of the ceiling machine and improving the heat exchange efficiency of the ceiling machine.

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

[0062] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. 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. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
