Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of air treatment equipment, in particular to a ceiling machine and air conditioner with same. BACKGROUND

[0002] The ceiling machine is an air conditioning equipment capable of being embedded and installed on an indoor ceiling. The air supply direction of the ceiling machine is downward, which causes the user to be easily subjected to direct blowing of the air conditioner air in the room, resulting in poor user experience. Since the current air deflector of the ceiling machine is usually a straight plate, the air deflector directly deflects the air outlet by a large angle (for example, the air outlet direction is deflected to an angle of 10°-20° with the horizontal direction), which causes a large included angle between the air deflector and the downward blown air flow, and the air flow directly impacts on the air deflector, resulting in large air loss of the air outlet, and thus reducing the air volume of the air outlet of the ceiling machine. Therefore, how to make the air outlet of the ceiling machine not directly blow the user and also ensure that the ceiling has a large air volume becomes a problem to be solved. SUMMARY

[0003] In view of the above problems, the utility model is proposed to provide a ceiling machine and air conditioner with same which overcome the above problems or at least partially solve the above problems.

[0004] An object of the utility model is to make the air outlet of the ceiling machine not directly blow the user and simultaneously ensure that the ceiling has a large air volume.

[0005] Specifically, the utility model provides a ceiling machine, which comprises: a shell defining a downwardly open air outlet; an air deflector rotatably arranged at the air outlet; and a windward surface of the air deflector comprising: an air inlet curved surface section recessed toward a leeward surface of the air deflector; an air outlet curved surface section recessed toward the leeward surface of the air deflector; and a transition section smoothly connected between the air inlet curved surface section and the air outlet curved surface section.

[0006] In some embodiments, an included angle between a tangent plane of an air inlet end of the air inlet curved surface section and a tangent plane of an air outlet end of the air outlet curved surface section is 120°-130°.

[0007] In some embodiments, the ceiling machine further comprises: a driving device installed in the shell, the driving device being configured to drive the air deflector to rotate and to drive the air deflector to rotate to at least a position at which an included angle between the tangent plane of the air outlet end of the air outlet curved surface section and a horizontal plane is 9°-11°.

[0008] In some embodiments, the ceiling machine further comprises: a temperature detection device configured to detect an indoor temperature to control the driving device according to the indoor temperature.

[0009] In some embodiments, the air outlet is multiple, and the corresponding air deflector and the driving device are multiple, and the multiple driving devices are independently controlled.

[0010] In some embodiments, the included angle between the section of the air inlet end of the air inlet curved section and the transition section is smaller than the included angle between the section of the air outlet end of the air outlet curved section and the transition section.

[0011] In some embodiments, the air deflector comprises a plate body, the plate body comprises a first curved section, a straight plate section and a second curved section connected in sequence, the inner surface of the first curved section forms the air inlet curved section, the inner surface of the second curved section forms the air outlet curved section, and the inner surface of the straight plate section forms the transition section.

[0012] In some embodiments, the air deflector further comprises a mounting member rotatably arranged at the air outlet, and the first curved section, the straight plate section and the second curved section are connected with the mounting member.

[0013] In some embodiments, the shell comprises a face cover, the air outlet is arranged on the face cover, the face cover has an attached wall portion arranged at the air outlet, and the inner edge of the attached wall portion is connected with the air outlet; the attached wall portion is arranged obliquely, and the inner edge of the attached wall portion is located below the outer edge of the attached wall portion.

[0014] The air conditioner comprises the ceiling machine according to any one of the preceding embodiments.

[0015] The air deflector of the ceiling machine has an air inlet curved section, a transition section and an air outlet curved section connected in sequence, and the air inlet curved section and the air outlet curved section are both arc surfaces recessed towards the leeward surface of the air deflector. In order to prevent the blown air conditioner air from directly blowing on the user, when the air deflector is rotated to offset the air outlet direction in the horizontal direction, for example, the included angle between the tangent line of the air outlet end of the air deflector and the horizontal direction is 10°-20°, at least part of the airflow of the air outlet will flow through the air inlet curved section, the transition section and the air outlet curved section in sequence, and then be blown into the indoor room by the air outlet curved section. Therefore, the airflow can be smoothly guided by the air inlet curved section and the air outlet curved section to change the blowing direction of the airflow, and the air loss of the air outlet is reduced. Especially when the airflow flows through the air inlet curved section, the included angle between the tangent line of the air inlet end of the air inlet curved section and the vertical direction is small, which avoids the direct impact of the airflow on the air deflector, thereby greatly reducing the air loss of the air outlet. Therefore, the ceiling machine can prevent the air outlet of the ceiling machine from directly blowing on the user, and at the same time ensure a large air outlet air volume.

[0032] The ceiling machine 10 of the embodiments of the present application is described below with reference to the drawings.

[0033] As Figures 1-7 shown, the ceiling machine 10 of the embodiment of the utility model includes a shell 100 and a guide vane 200.

[0034] The ceiling machine 10 of the embodiment of the utility model is arranged on the ceiling in the room, the shell 100 defines the air outlet 110 that opens downward, and the air outlet 110 is arranged at the lower part of the shell 100.When the ceiling machine 10 blows air, the air outlet 110 blows cold air or hot air downward, thereby adjusting the temperature in the room. Since the ceiling machine 10 of the embodiment of the utility model can be embedded on the ceiling in the room, the active area of the user in the room is not occupied, and the use experience of the user is better.

[0035] The guide vane 200 is rotatably arranged at the air outlet 110, and the rotation of the guide vane 200 makes the guide vane 200 form a certain included angle with the air outlet direction, thereby making the guide vane 200 guide the air outlet of the air outlet 110 to blow out at different angles.

[0036] The windward surface 210 of the guide vane 200 includes an air inlet curved surface section 230, a transition section 250 and an air outlet curved surface section 240, that is, the side surface of the guide vane 200 close to the inner end of the air outlet 110 is formed with the air inlet curved surface section 230, the transition section 250 and the air outlet curved surface section 240 connected in sequence, and the air inlet curved surface section 230 and the air outlet curved surface section 240 are both arc surfaces. The air inlet curved surface section 230 is recessed toward the leeward surface 220 of the guide vane 200, and the air outlet curved surface section 240 is recessed toward the leeward surface 220 of the guide vane 200. The transition section 250 is smoothly connected between the air inlet curved surface section 230 and the air outlet curved surface section 240, that is, the air inlet end of the transition section 250 is smoothly connected with the air outlet end 232 of the air inlet curved surface section 230, and the air inlet end of the transition section 250 is smoothly connected with the air outlet curved surface section 240.

[0037] The air inlet curved surface section 230 and the air outlet curved surface section 240 are both arc surfaces recessed toward the leeward surface 220 of the guide vane 200, the tangent line of the air inlet end 231 of the air inlet curved surface section 230 and the tangent line of the air outlet end form a certain included angle, for example, 150°. The tangent line of the air inlet end 241 of the air outlet curved surface section 240 and the tangent line of the air outlet end also form a certain included angle, for example, 140°. That is, in the process that the air outlet of the air outlet 110 flows from the air inlet end 231 of the air inlet curved surface section 230 to the air outlet end 242 of the air outlet curved surface section 240, the flow of the airflow can be smoothly guided by the air inlet curved surface section 230 and the air outlet curved surface section 240, thereby changing the blowing direction of the airflow. In order to realize that the air outlet of the ceiling machine 10 does not blow directly to the user, the airflow needs to be guided to change the angle greatly. Since the outlet airflow is smoothly guided through the air inlet curved surface section 230 and the air outlet curved surface section 240, the wind loss of the outlet airflow is greatly reduced, and the air volume of the ceiling machine 10 of the embodiment of the utility model is ensured to be large.

[0038] Compared with the related art, the air outlet deflector 200 of the ceiling air conditioner 10 has the air inlet curved surface section 230, the transition section 250 and the air outlet curved surface section 240 which are sequentially and smoothly connected, wherein the air inlet curved surface section 230 and the air outlet curved surface section 240 are both arc surfaces which are recessed towards the leeward surface 220 of the air outlet deflector 200. In order to prevent the air conditioner air from directly blowing to the user, when the air outlet deflector 200 is rotated to offset the air outlet direction of the air outlet 110 to the horizontal direction, for example, the tangent of the air outlet end of the air outlet deflector 200 and the horizontal direction forms an angle of 10°-20°, at least part of the airflow of the air outlet 110 will flow through the air inlet curved surface section 230, the transition section 250 and the air outlet curved surface section 240 in sequence, and then the air is blown into the indoor by the air outlet curved surface section 240. Therefore, the airflow can be smoothly guided by the air inlet curved surface section 230 and the air outlet curved surface section 240 to change the blowing direction of the airflow, and the air loss of the air outlet is reduced. Especially when the airflow flows through the air inlet curved surface section 230, the tangent of the air inlet end 231 of the air inlet curved surface section 230 and the vertical direction forms a small angle, which avoids the airflow from directly impacting on the air outlet deflector 200, thereby greatly reducing the air loss of the air outlet. Therefore, the ceiling air conditioner 10 can prevent the air outlet of the ceiling air conditioner 10 from directly blowing to the user, and at the same time ensure a large air outlet air volume.

[0039] As shown in Figures 1-7 The shell 100 of the ceiling air conditioner 10 includes a face cover 120, and the face cover 120 is provided with the air outlet 110. The air outlet 110 and the air outlet deflector 200 are both multiple, and the multiple air outlets 110 are distributed in the circumferential direction of the face cover 120. The multiple air outlet deflectors 200 correspond to the multiple air outlets 110 one by one, and each air outlet deflector 200 guides the direction of the air outlet of the corresponding air outlet 110.

[0040] The air outlet deflector 200 includes a plate body 260, and the plate body 260 includes a first curved section 261, a straight plate section 262 and a second curved section 263 which are sequentially connected. The inner surface of the first curved section 261 forms the air inlet curved surface section 230, the inner surface of the second curved section 263 forms the air outlet curved surface section 240, and the inner surface of the straight plate section 262 forms the transition section 250. Therefore, the air inlet curved surface section 230 and the air outlet curved surface section 240 are respectively formed by the first curved section 261 and the second curved section 263, which not only can smoothly guide the air outlet airflow, but also has a simple structure.

[0041] Further, as shown in Figures 2-5As shown, the air deflector 200 further comprises a mounting piece 270 rotatably arranged at the air outlet 110. The first curved section 261, the straight plate section 262 and the second curved section 263 are connected with the mounting piece 270, so that the structure of the air deflector 200 is more stable by connecting the lower end of the mounting piece 270 with the first curved section 261, the straight plate section 262 and the second curved section 263, and the service life of the air deflector 200 is prolonged.

[0042] Specifically, the ceiling machine 10 comprises four air outlets 110 and four air deflectors 200. Two air outlets 110 are arranged at intervals in a first horizontal direction and extend in a second horizontal direction perpendicular to the first horizontal direction. The other two air outlets 110 are arranged at intervals in the second horizontal direction and extend in the first horizontal direction. The four air deflectors 200 are arranged one by one at the four air outlets 110 respectively.

[0043] In some embodiments of the utility model, as shown in Figure 6 As shown, the included angle between the tangent plane of the air inlet end 231 of the air inlet curved section 230 and the tangent plane of the air outlet end 242 of the air outlet curved section 240 is 120-130°. Wherein, the included angle between the tangent plane of the air inlet end 231 of the air inlet curved section 230 and the tangent plane of the air outlet end 242 of the air outlet curved section 240 is α, and the included angle between the tangent plane of the air inlet end 231 of the air inlet curved section 230 and the vertical plane is β.

[0044] Optionally, the included angle α is 120-130°; or the included angle α is 122-128°; or the included angle α is 124-126°.

[0045] Wherein, the included angle α includes but is not limited to 120°, 121°, 122°, 123°, 124°, 125°, 126°, 127°, 128°, 129° or 130°.

[0046] The inventor found that when the tangent plane of the air outlet end 242 of the air outlet curved section 240 is rotated to an included angle of 10° with the horizontal plane, the air outlet 110 is easy to adhere to the ceiling, and forms a wall-attached jet, and then reaches the bottom area of the indoor through the ceiling and the vertical wall surface connected with the ceiling. Especially when the air outlet of the ceiling machine 10 is hot air, the wind loss of the hot air is greatly reduced, so as to not only achieve the purpose that the hot air cannot blow directly to the user, but also make the hot air fall better, and make the indoor temperature more uniform.

[0047] The included angle between the tangent plane of the air inlet end 231 of the air inlet curved surface section 230 and the tangent plane of the air outlet end 242 of the air outlet curved surface section 240 is 120° to 130°, so that the included angle between the tangent plane of the air inlet end 231 of the air inlet curved surface section 230 and the vertical plane is 20° to 30° when the tangent plane of the air outlet end 242 of the air outlet curved surface section 240 is rotated to an angle of 10° with the horizontal plane. That is, the included angle between the tangent plane of the air inlet end 231 of the air inlet curved surface section 230 and the vertical plane is 20° to 30° when the tangent plane of the air outlet end 242 of the air outlet curved surface section 240 is rotated to an angle of 10° with the horizontal plane, that is, the included angle between the tangent plane of the air inlet end 231 of the air inlet curved surface section 230 and the downward flowing air flow is 20° to 30°, so that the air flow is not directly impacted on the air deflector 200, thereby greatly reducing the wind loss of the air outlet.

[0048] Further, the included angle between the tangent plane of the air inlet end 231 of the air inlet curved surface section 230 and the transition section 250 is smaller than the included angle between the tangent plane of the air outlet end 242 of the air outlet curved surface section 240 and the transition section 250. Thus, the deflection angle of the air flow at the air inlet curved surface section 230 is further reduced, thereby further reducing the wind loss of the air outlet.

[0049] In some embodiments of the present application, as shown in Figure 2 and Figure 3 The ceiling machine 10 of the present application further comprises a driving device 300 installed in the housing 100, and the driving device 300 is configured to drive the air deflector 200 to rotate, and is configured to drive the air deflector 200 to rotate to at least a position where the tangent plane of the air outlet end 242 of the air outlet curved surface section 240 is at an angle of 9° to 11° with the horizontal plane. Thus, the driving device 300 is used to control the rotation of the air deflector 200, so that the air deflector 200 can be rotated to a position where the tangent plane of the air outlet end 242 of the air outlet curved surface section 240 is at an angle of 9° to 11° with the horizontal plane, so that the ceiling machine 10 of the present application has a simple structure and is easy to manufacture.

[0050] Further, the ceiling machine 10 of the present application further comprises a temperature detection device 400 configured to detect the indoor temperature, so as to control the driving device 300 according to the indoor temperature, thereby rotating the air deflector 200 to a position where the tangent plane of the air outlet end 242 of the air outlet curved surface section 240 is at an angle of 9° to 11° with the horizontal plane when the indoor temperature reaches a preset temperature.

[0051] The ceiling machine 10 directly blows air downward before the indoor temperature reaches the preset value, so that the indoor temperature quickly reaches the preset temperature, for example, 25 degrees. After the indoor temperature reaches the preset temperature, the driving device 300 controls the deflector 200 to rotate to a position where the angle between the tangent plane of the air outlet end 242 of the air outlet curved section 240 and the horizontal plane is 9-11 degrees, thereby ensuring the indoor temperature and preventing the air from directly blowing on the user, thereby further improving the user experience.

[0052] Further, in the case of multiple air outlets 110, the corresponding deflectors 200 and driving devices 300 are also multiple, and the multiple driving devices 300 are independently controlled. Thus, the air outlet directions of the multiple air outlets 110 are independently controllable, thereby facilitating the user to adjust according to the user's own needs and improving the user experience.

[0053] In some embodiments of the present application, as shown in Figure 2 and Figure 3 The face cover 120 has an attached wall portion 121, which is arranged at the air outlet 110, and the inner edge 122 of the attached wall portion 121 is connected to the air outlet 110. The attached wall portion 121 is inclinedly arranged, and the inner edge 122 of the attached wall portion 121 is located below the outer edge 123 thereof.

[0054] When the air outlet 110 blows air into the room, at least part of the airflow will adhere to the attached wall portion 121 and form an attached wall jet. Since the attached wall portion 121 extends outwardly and is inclinedly arranged upwardly, the jet adhering to the attached wall portion 121 will flow along the attached wall portion 121 to the ceiling area, thereby reducing the energy loss of the air outlet 110 during the air outlet 110 flowing to the ceiling, i.e., further reducing the wind loss of the air outlet.

[0055] The air conditioner of the present application comprises the ceiling machine 10 of any one of the above embodiments.

[0056] The air conditioner has the air outlet 110 of the ceiling machine 10, and the air outlet 110 is provided with the air deflector 200. The air deflector 200 comprises the air inlet curved section 230, the transition section 250 and the air outlet curved section 240 which are sequentially and smoothly connected. The air inlet curved section 230 and the air outlet curved section 240 are both arc surfaces which are concave to the leeward surface 220 of the air deflector 200. In order to prevent the blown air conditioner air from directly blowing the user, when the air deflector 200 is rotated to offset the air outlet 110 to the horizontal direction, at least part of the airflow of the air outlet 110 will flow through the air inlet curved section 230, the transition section 250 and the air outlet curved section 240 in sequence, and then the air is blown into the indoor by the air outlet curved section 240. Therefore, the airflow can be smoothly guided by the air inlet curved section 230 and the air outlet curved section 240, so as to change the blowing direction of the airflow and reduce the air loss. Therefore, the ceiling machine 10 can prevent the air outlet of the ceiling machine 10 from directly blowing the user, and ensure a large air volume at the same time.

[0057] At this point, those skilled in the art should recognize that, although the present application has been shown and described in detail in this paper, many other variants or modifications conforming to the principles of the present application can be directly determined or deduced according to the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variants or modifications.
