Detailed Implementation

[0042] The technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0043] In the description of the present application, it should be understood that the terms "center", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the scope of protection of the present application.

[0044] In the related art, the roof unit is usually provided with a selectable air inlet for realizing different air outlet and return modes, so as to meet different installation requirements of users. However, due to the difference in position and orientation of different air inlets, the air volume of air outlet and return is greatly different, resulting in great difference in refrigeration effect of the roof unit under different air outlet and return modes.

[0045] Based on this, the present application provides an air conditioner, which can include a roof unit. By improving the installation mode of the fan in the air conditioner, the difference in refrigeration or heating effect of the air conditioner under different air outlet and return modes can be reduced, and the user experience can be improved.

[0046] Reference Figure 1 and Figure 2 In some embodiments, the air conditioner includes a bottom plate 1, a cabinet and a fan 3. The bottom plate 1 is provided with a first air outlet 101. The cabinet is covered on the bottom plate 1 to form an installation space 100a between the cabinet and the bottom plate 1. The cabinet includes a side plate 2 connected at an angle with the bottom plate 1, and the side plate 2 is provided with a second air outlet 201. The fan 3 is arranged in the installation space 100a, the first air outlet 101 and the second air outlet 201 are configured to selectively output the airflow output by the fan outlet of the fan 3, and the first included angle between the air outlet direction of the fan outlet and the air outlet direction of the first air outlet 101 and the second included angle between the air outlet direction of the fan outlet and the air outlet direction of the second air outlet 201 are both less than 90 degrees.

[0047] In the embodiment of the utility model, first air outlet 101 and second air outlet 201 are used to send air to output the airflow that is heated or cooled to the target position (for example, the indoor area of a building). By designing the first included angle between the air outlet direction of the fan air outlet of fan 3 and the air outlet direction of first air outlet 101 and the second included angle between the air outlet direction of the fan air outlet of fan 3 and the air outlet direction of second air outlet 201 to be within 90 degrees, it is helpful to reduce the airflow fluctuation or energy loss caused by direction change or collision with the air duct structure when the airflow output by fan 3 flows to first air outlet 101 or second air outlet 201, thereby improving the stability and consistency of the airflow output by first air outlet 101 or second air outlet 201. Further, by reasonably setting the size of the first included angle and the second included angle, the air outlet flow of first air outlet 101 and second air outlet 201 can be brought to a similar state, the difference in air outlet effect of first air outlet 101 and second air outlet 201 is reduced, and it is helpful to reduce the difference in refrigeration or heating effect of the air conditioner under different air outlet modes. It is also convenient to achieve similar refrigeration or heating effect under the same control program under different air outlet modes.

[0048] As an example, reference is made to Figure 2 The first included angle is shown as α, and the second included angle is shown as β.

[0049] The size of the first included angle α and the second included angle β can be designed based on comprehensive consideration of factors such as the overall height of the air conditioner, the cabinet volume, and the installation convenience of fan 3.

[0050] In the process of designing the size of the first included angle α and the second included angle β, in order to more clearly explore the influence of the size of the first included angle α and the second included angle β in the air conditioner on the air volume distribution in the air outlet and return process of the air conditioner, the inventors simulated and calculated the in-machine air field of the air conditioner with the first included angle α being 60 degrees, 75 degrees and 90 degrees respectively under the condition that the bottom plate 1 is perpendicular to the side plate 2 and the second included angle is complementary to the first included angle. The working conditions of air outlet from first air outlet 101 and air return from first air return 102 (bottom-out bottom-return), and air outlet from second air outlet 201 and air return from second air return 202 (side-out side-return) are simulated and calculated respectively, and the corresponding air return volume is counted. The arrangement of first air return 102, second air return 202 and related air ducts will be introduced later.

[0051] In some embodiments, fan 3 in the utility model can be a centrifugal fan.

[0052] Reference is made to Figure 3 , Figure 4 and Figure 5 , which respectively show the air field simulation diagram with the first included angle α being 60 degrees, 75 degrees and 90 degrees.

[0053] According to the simulation results, when the first included angle a is 60 degrees, the difference in return air volume between the bottom return and the side return is 3.1%; when the first included angle a is 75 degrees, the difference in return air volume between the bottom return and the side return is 16.3%; and when the first included angle a is 90 degrees (i.e., the commonly used scheme in the related art), the difference in return air volume between the bottom return and the side return is 23.1%.

[0054] It can be seen that, in the above three schemes, the scheme with the first included angle a of 60 degrees achieves the best effect of reducing the difference in return air volume between different return air modes.

[0055] Based on the simulation calculation results described above and taking into account the overall height of the air conditioner, the cabinet volume, and the installation convenience of the fan 3, the inventor designed the following several feasible design schemes for the size of the first included angle. The size of the second included angle can be further calculated and designed based on the size of the first included angle, the structure of the cabinet, and the layout of the internal environment of the cabinet, and is not limited herein.

[0056] For example, in some embodiments, the size of the first included angle a is 60-80 degrees.

[0057] This angle range helps to make the air flow rates of the first air outlet 101 and the second air outlet 201 reach a reasonable range and the flow rate difference between the two air outlets be within an acceptable range.

[0058] In another embodiment, the size of the first included angle a is 65-75 degrees.

[0059] This angle range helps to further make the air flow rates of the first air outlet 101 and the second air outlet 201 reach a reasonable range and the flow rate difference between the two air outlets be within an acceptable range.

[0060] In a specific example, the size of the first included angle a is 71 degrees.

[0061] In actual applications, the required first included angle and second included angle can be obtained by specific structural design and layout of the air conditioner. For example, the position and orientation of the air outlet of the fan 30 in the installation space 100a are reasonably laid out. Alternatively, the relative angle of the bottom plate 1 and the side plate 2 can be designed. For another example, the installation position and angle of the fan 30 relative to the bottom plate 1 and the side plate 2 can also be set.

[0062] In some embodiments, the bottom plate 1 is perpendicular to the side plate 2, and the second included angle is complementary to the first included angle.

[0063] The bottom plate 1 and the side plate 2 are arranged perpendicularly to each other, so that the air conditioner has a simple and regular structure, facilitating installation and transportation. Correspondingly, the second included angle is complementary to the first included angle, and the bottom plate 1 and the side plate 2 can guide the airflow in the installation space 100a, which helps the first air outlet 101 and the second air outlet 201 to obtain stable air outlet effects.

[0064] In some embodiments, the air conditioner further comprises a mounting portion on which the fan 3 is mounted, the mounting portion has a bottom mounting plane, and the mounting portion is mounted on the bottom plate 1 and has an included angle less than 90 degrees between the bottom mounting plane and the bottom plate 1, so that the first included angle is less than 90 degrees.

[0065] Here, the bottom mounting plane of the mounting portion is arranged obliquely relative to the bottom plate 1, so that the fan outlet of the fan 3 is also oblique relative to the bottom plate 1, thereby forming the first included angle less than 90 degrees between the air outlet direction of the fan outlet of the fan 3 and the air outlet direction of the first air outlet 101.

[0066] The mounting portion can load and support the fan 3, and by mounting the mounting portion on the bottom plate 1, the installation of the fan 3 can be realized. The mounting portion actually plays a protective role for the fan, which can effectively reduce the damage caused by directly installing and dismounting the fan 3, especially the damage to the moving parts in the fan.

[0067] Further, during the production and manufacturing of the air conditioner, the mounting portion and the fan 3 can be integrated to form a module that can be separately mounted and dismounted, thereby facilitating the transportation, installation and other processes. Specifically, the user does not need to install the fan 3 and the mounting portion separately, but directly installs the entire integrated module, which can save the time and labor cost required for installation. Especially when rapid deployment or replacement of equipment is required, work efficiency can be improved.

[0068] Among them, the structure of the mounting portion has various options, such as support plate structure, box structure, frame structure, etc.

[0069] Reference Figure 2 and Figure 6 As shown in the drawings, in some embodiments, the mounting portion comprises a mounting frame 4, and the fan 3 is mounted in the mounting frame 4, and the mounting frame 4 is mounted on the bottom plate 1.

[0070] The frame-shaped mounting frame 4 has the characteristics of large ventilation area, stable structure, light weight, etc., which can provide sufficient air outlet and return space for the fan 3, and also provide good support, and its lightness also facilitates transportation and installation.

[0071] Here, the fan 3 is mounted in the space surrounded by the frame of the mounting frame 4, and the bottom mounting plane of the mounting frame 4 refers to the plane where the bottom edges of the frames at both ends of the fan 3 are located.

[0072] Reference Figure 2 As shown in some embodiments, the air conditioner further comprises a mounting plate 5 and a motor 6 for driving the fan 3, the cabinet further comprises a top plate 7 parallel to the bottom plate 1, the mounting plate 5 is connected to the top end of the mounting portion and located above the volute of the fan 3, and the mounting plate 5 is inclined relative to the top plate 7 to form an accommodation space between the top plate 7 and the mounting plate 5, and the motor 6 is mounted on the mounting plate 5 and located in the accommodation space.

[0073] The mounting plate 5 plays a role in supporting the motor 6. And by the inclined design of the mounting plate 5, the motor 6 is installed in the accommodation space formed between the top plate 7 and the mounting plate 5, effectively utilizing the available space inside the cabinet. Such a setup helps to reduce the volume of the air conditioner, making the overall layout of the air conditioner more compact, so as to better adapt to complex or limited installation environments. In addition, during transportation of the air conditioner, the fan 3 and the motor 6 can also be compactly packaged, for example, uniformly packaged in the cabinet for transportation, which can effectively save storage space, improve the installation capacity, and help reduce transportation costs.

[0074] Reference Figure 7 As shown in the related art, the layout of the fan 30a and the motor 60a is shown, in which the height of the motor 60a relative to the bottom plate 10a is high, even protruding from the top of the cabinet, which will significantly reduce the installation capacity during transportation, and it is not convenient to arrange the air duct in the effective space of the installation.

[0075] In some embodiments of the present application, the mounting portion is at least partially embedded in the bottom plate 1.

[0076] The mounting portion is embedded in the bottom plate 1, on the one hand, making the combination between the bottom plate 1 and the mounting portion more compact, enhancing the stability of the installation, on the other hand, it also helps to reduce the occupation of the mounting portion to the installation space 100a, further optimizing the space utilization efficiency inside the cabinet.

[0077] Reference Figure 8 and Figure 9 As shown in some embodiments, the air conditioner further comprises a first bracket 8 mounted on the upper surface of the bottom plate 1, the first bracket 8 is provided with a first support surface 801 inclined relative to the upper surface of the bottom plate 1, the end of the first support surface 801 away from the first air outlet 101 is higher than the end close to the first air outlet 101, the mounting portion is mounted on the first bracket 8, and the bottom mounting plane abuts against the first support surface 801.

[0078] The first support 8 is used to provide stable support for the mounting portion and fix the mounting portion to the bottom plate 1. By arranging the first support surface 801 on the first support 8 to be inclined relative to the upper surface of the bottom plate 1, the inclined installation of the mounting portion relative to the bottom plate 1 can be achieved. Further, by adjusting the inclination of the first support surface 801, the inclination of the mounting portion relative to the bottom plate 1 can be adjusted, and thus the size of the first included angle or the second included angle can be adjusted.

[0079] Referring to Figure 8 As shown in some embodiments, the bottom plate 1 is provided with a mounting groove 103, and the air conditioner further comprises a second support 10 mounted in the mounting groove 103. Referring to Figure 11 As shown, the second support 10 is provided with a second support surface 1001 inclined relative to the upper surface of the bottom plate 1, and the end of the second support surface 1001 away from the first air outlet 101 is higher than the end of the second support surface 1001 close to the first air outlet 101. The mounting portion is mounted on the second support 10, and the bottom mounting plane abuts against the second support surface 1001.

[0080] The mounting groove 103 provides a certain space inside for mounting the second support 10, which can accommodate and limit the second support 10, helping to fix the second support 10, and thus ensuring the installation stability of the mounting portion. By arranging the second support surface 1001 on the second support 10 to be inclined relative to the upper surface of the bottom plate 1, the inclined installation of the mounting portion relative to the bottom plate 1 can be achieved. Further, by adjusting the inclination of the second support surface 1001, the inclination of the mounting portion relative to the bottom plate 1 can be adjusted, and thus the size of the first included angle or the second included angle can be adjusted.

[0081] Further, the size and depth of the mounting groove 103 can also be set to partially accommodate the mounting portion, so that the mounting portion can be at least partially embedded in the bottom plate 1. For example, when the mounting portion is a frame structure, the mounting groove 103 can accommodate part of the structure of the bottom of the frame, so that the frame is partially embedded in the bottom plate 1, thereby reducing the occupation of the mounting portion to the mounting space 100a, facilitating the layout of more other components in the mounting space 100a, and improving the space utilization.

[0082] In some examples provided with both the first support 8 and the second support 10, the inclinations of the first support surface 801 and the second support surface 1001 relative to the bottom plate 1 can be set to be consistent, so that the first support surface 801 and the second support surface 1001 jointly provide support for the mounting portion and the fan 3 mounted on the mounting portion, improving the installation stability of the mounting portion and the fan 3.

[0083] In the embodiments of the utility model, the number and arrangement position of the first support 8 or the second support 10 are not limited. In the process of arranging and installing the mounting portion and the fan 3, the number and arrangement position of the required first support 8 or second support 10 can be selected and adjusted according to factors such as weight, size, shape and installation position, so that the mounting portion and the fan 3 can be stably installed on the bottom plate 1.

[0084] The structure of the first support 8 or the second support 10 can also be adjusted according to actual needs. For example, in some embodiments, as shown in Figure 8 、 Figure 9 and Figure 10 , the first support 8 and the second support 10 are both configured as plate-shaped support structures with bending, and the cross section can be square, trapezoidal, etc., to provide stable support.

[0085] As shown in Figure 12 and Figure 13 , in some embodiments, the bottom plate 1 includes a frame portion 1a and a cover plate portion 1b, and the cover plate portion 1b is covered on the frame portion 1a. The upper surface of the bottom plate 1 is formed on the surface of the cover plate portion 1b. The frame structure of the frame portion 1a can provide stable support and can reserve enough space for installing and accommodating other related components.

[0086] As shown in Figure 14 , the first support 8 can be fixed to the cover plate portion 1b by the first bolt 14. The second support 10 can be fixed into the mounting groove 103 by the second bolt 15. The first bolt 14 and the second bolt 15 can be the same or different bolts, which can be selected according to the connection strength and installation convenience.

[0087] In the installation process of the air conditioner, the mounting portion and the fan 3 can be integrally installed on the bottom plate 1 through the first bolt 14 and the second bolt 15. When the fan 3 needs to be maintained or replaced later, the mounting portion and the fan 3 in the mounting portion can be quickly disassembled by disassembling the first bolt 14 and the second bolt 15.

[0088] In some embodiments, as shown in Figure 12 , the bottom plate 1 further includes a fixed portion 1c. The fixed portion 1c is connected in the space surrounded by the four cross beams of the frame portion 1a, and the fixed portion 1c includes a plurality of baffles which together surround the mounting grooves 103 for accommodating the second supports 10 at both ends of the fixed portion 1c.

[0089] As an example, the bottom of the mounting groove 103 is fixedly connected with a second bolt 15, such as a spot-welded bolt, so that the second bracket 10 can be fixedly connected to the fixing part 1c by the first bolt 14. The multiple baffles of the fixing part 1c play a protective role, and the mounting groove 103 formed by it can prevent the second bracket 10 and the mounting part or fan 3 connected to the second bracket 10 from being affected by moisture or dust from other parts of the base plate 1.

[0090] refer to Figure 8 As shown, in some embodiments, the air conditioner further includes a partition 9, which is vertically mounted on the base plate 1 to divide the area above the base plate 1 into at least a first area and a second area, with the first air outlet 101 located in the first area. (Reference) Figure 10 As shown, at least one first bracket 8 has a slot 802 on the side near the base plate 1. The slot 802 is configured to engage with the partition plate 9 so that the end of the first bracket 8 away from the first air outlet 101 is located in the second region, and the end of the first bracket 8 near the first air outlet 101 is located in the first region.

[0091] The partition 9 is used for partitioning, which facilitates the rational layout of various components in the air conditioner and makes maintenance and management easier. Alternatively, the first and second zones can be areas that connect the indoor and outdoor zones of the air conditioner, respectively. In this case, the partition 9 can effectively prevent rainwater or dust from the outdoor zone from entering the indoor zone, thereby ensuring the normal operation of various components in the indoor zone.

[0092] In some embodiments, reference Figure 15 The air conditioner also includes an evaporator 11 disposed in the installation space 100a. The air intake direction of the fan 3 is parallel to the base plate 1. The evaporator 11 is vertically mounted on the base plate 1 so that the air outlet direction of the evaporator 11 is parallel to the air intake direction of the fan 3.

[0093] Here, the evaporator 11 is mounted vertically on the base plate 1, that is, the ventilation surface of the evaporator 11 is perpendicular to the base plate 1. By setting the air inlet direction of the fan 3 to be parallel to the base plate 1 and the ventilation surface of the evaporator 11 to be perpendicular to the base plate 1, the airflow passing through the evaporator 11 can flow into the fan 3 quickly and directly. The heat exchange efficiency of the airflow is high and the transmission path is continuous, which helps to provide sufficient air volume.

[0094] Furthermore, the vertical design of the evaporator 11 occupies less space, allowing for efficient use of the installation space 100a, which in turn facilitates the arrangement of other air conditioning components within the installation space 100a. These components include, for example, the electrical box 12 and the refrigerant delivery piping 13. Figure 15 As shown. Those skilled in the art will understand that components such as the electrical box 12 and the working fluid delivery pipeline 13 are commonly used components in the refrigeration cycle of air conditioners or air conditioning units, and will not be described in detail here.

[0095] Reference Figure 1 and Figure 16 As shown in FIG. 1, in some embodiments, a first return air inlet 102 is further arranged on the bottom plate 1, and a second return air inlet 202 is further arranged on the side plate 2. Referring to FIG. 2, the evaporator 11 divides the installation space 100a into an air outlet space 100b and a return air space 100c, and the fan 3 is located in the air outlet space 100b. The first air outlet 101 and the second air outlet 201 are both in communication with the air outlet space 100b, and the first return air inlet 102 and the second return air inlet 202 are both in communication with the return air space 100c. Figure 15

[0096] Here, the evaporator 11 is arranged between the air outlet space 100b and the return air space 100c, and the air enters the return air space 100c through the first return air inlet 102 or the second return air inlet 202, and then further exchanges heat at the evaporator 11 to reach the required temperature, and is then sucked into the air outlet space 100b by the fan 3 and is delivered to the air outlet space 100b, and then is output through the first air outlet 101 or the second air outlet 201. Based on this, the air realizes continuous flow in a limited space and reaches different states in different spaces, realizing efficient and stable air flow management.

[0097] Here, the fan 3 and the first air outlet 101 and the second air outlet 201 can be provided with air ducts for delivering air flow to improve the delivery efficiency of the air flow.

[0098] In actual application, different air return and air outlet schemes can be selected according to user needs, for example, a scheme of returning air from the first return air inlet 102 and outputting air from the first air outlet 101, or a scheme of returning air from the second return air inlet 202 and outputting air from the second air outlet 201, to adapt to different air supply needs or installation environments.

[0099] In the embodiments of the present application, the number and position of the air outlets and the return air inlets are not limited. In addition to arranging two groups of air outlets and return air inlets as in the above embodiments, three groups, four groups or even more groups of air outlets and return air inlets can be adaptively arranged according to different air supply needs. Correspondingly, the number of the fan 3 can also be adjusted. One fan can correspond to one group of air outlets and return air inlets, or one fan can correspond to multiple groups of air outlets and return air inlets, as long as the air ducts are reasonably arranged.
