DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0044] In the related art, rooftop units are usually provided with selectable air outlets to achieve different air outlet and return modes, so as to meet different installation requirements of users. However, due to the differences in the positions and directions of different air outlets, the air volume of the air outlet and return varies greatly, resulting in large differences in the cooling effect of the rooftop units under different air outlet and return modes.

[0045] Based on this, the present invention provides an air conditioner, which may include a rooftop unit or a rooftop unit. By improving the installation method of the fan in the air conditioner, the difference in cooling or heating effects of the air conditioner under different air outlet and return modes can be reduced, thereby improving user experience.

[0046] refer to Figure 1 and Figure 2 In some embodiments, the air conditioner includes a base plate 1, a housing and a fan 3. The base plate 1 is provided with a first air outlet 101. The housing cover is provided on the base plate 1 to form an installation space 100a between the housing and the base plate 1. The housing includes a side panel 2 connected to the base plate 1 at an angle, and a second air outlet 201 is provided on the side panel 2. The fan 3 is arranged in the installation space 100a, and 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 angle between the air outlet direction of the fan outlet and the air outlet direction of the first air outlet 101 and the second angle between the air outlet direction of the fan outlet and the second air outlet 201 are both less than 90 degrees.

[0047] In the embodiment of the present invention, the first air outlet 101 and the second air outlet 201 are used for air supply to output heated or cooled airflow to a target location (e.g., an indoor area of ​​a building). By designing the first angle between the air outlet direction of the fan outlet of the fan 3 and the air outlet direction of the first air outlet 101, and the second angle between the air outlet direction of the fan outlet of the fan 3 and the air outlet direction of the second air outlet 201 to be within 90 degrees, it is helpful to reduce the airflow fluctuation or energy loss caused by the change of direction or collision with the air duct structure when the airflow output by the fan 3 flows to the first air outlet 101 or the second air outlet 201, thereby improving the stability and consistency of the airflow output by the first air outlet 101 or the second air outlet 201. Furthermore, by reasonably setting the size of the first angle and the second angle, the air flow rate of the first air outlet 101 and the second air outlet 201 can be made similar, reducing the difference in the air outlet effect of the first air outlet 101 and the second air outlet 201, which helps to reduce the difference in the cooling or heating effect of the air conditioner under different air outlet modes. It is also convenient to use the same set of control programs to achieve similar cooling or heating effects under different air outlet modes.

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

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

[0050] In the process of designing the size of the first angle α and the second angle β, in order to more clearly explore the influence of the size of the first angle α and the second angle β in the air conditioner on the air volume distribution during the air outlet and return process of the air conditioner, the inventor simulated and calculated the wind field conditions inside the air conditioner with the first angle α of 60 degrees, 75 degrees and 90 degrees respectively, when the bottom plate 1 is perpendicular to the side plate 2 and the second angle is complementary to the first angle. The working conditions of air outlet from the first air outlet 101, air return from the first return air outlet 102 (bottom outlet and bottom return), air outlet from the second air outlet 201, and air return from the second return air outlet 202 (side outlet and side return) were simulated and calculated, and the corresponding return air volume was counted. Among them, the arrangement of the first return air outlet 102, the second return air outlet 202 and the related air ducts will be introduced in the following.

[0051] In some embodiments, the fan 3 in the present invention may be a centrifugal fan.

[0052] refer to Figure 3 , Figure 4 and Figure 5 , respectively show the wind field simulation diagrams when the first angle α is 60 degrees, 75 degrees and 90 degrees.

[0053] According to the simulation results, when the first angle α is 60 degrees, the difference in return air volume between bottom-out and bottom-return and side-out and side-return is 3.1%; when the first angle α is 75 degrees, the difference in return air volume between bottom-out and bottom-return and side-out and side-return is 16.3%; when the first angle α is 90 degrees (that is, the commonly used scheme in the relevant technology), the difference in return air volume between bottom-out and bottom-return and side-out and side-return is 23.1%.

[0054] It can be seen that, among the above three solutions, the solution in which the first angle α is 60 degrees has the best effect in reducing the difference in return air volume under different air outlet and return modes.

[0055] Based on the above simulation calculation results, the inventors have designed the following feasible design schemes for the size of the first angle by comprehensively considering the overall height of the air conditioner, the amount of cabinets installed, and the convenience of installing the fan 3. The size of the second angle can be further calculated and designed based on the size of the first angle, the structure of the box, and the layout of the internal environment of the box, and is not limited here.

[0056] For example, in some embodiments, the first angle α is 60-80 degrees.

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

[0058] In some other embodiments, the first angle α is 65-75 degrees.

[0059] This angle range helps to further ensure that the air flow rates of the first air outlet 101 and the second air outlet 201 are within a reasonable range and the difference in flow rates between the two air outlets is within an acceptable range.

[0060] In a specific example, the first angle α is 71 degrees.

[0061] In practical applications, the required first angle and second angle can be obtained by carrying out 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 arranged. Alternatively, the relative angle between the bottom plate 1 and the side plate 2 can be designed in a targeted manner. For another example, the installation position and angle of the fan 30 as a whole 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 angle is complementary to the first angle.

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

[0064] In some embodiments, the air conditioner also includes a mounting portion, the fan 3 is installed on the mounting portion, the mounting portion has a bottom mounting plane, the mounting portion is installed on the base plate 1 and there is an angle less than 90 degrees between the bottom mounting plane and the base plate 1, so that the first angle is less than 90 degrees.

[0065] Here, the bottom mounting plane of the mounting portion is arranged tilted relative to the base plate 1 so that the fan outlet of the fan 3 is also tilted relative to the base plate 1, thereby forming a first 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 part can load and support the fan 3, and the fan 3 can be installed by mounting the mounting part on the bottom plate 1. The mounting part actually plays a protective role for the fan, and can effectively reduce the damage that may be caused by directly installing and disassembling the fan 3, especially the damage to the moving parts in the fan.

[0067] Furthermore, during the manufacturing process of the air conditioner, the installation part and the fan 3 can be integrated to form a module that can be separately installed and disassembled, thereby helping to simplify the transportation, installation and other processes. Specifically, the user does not need to install the fan 3 and the installation part separately, but can directly install the entire integrated module, which can save the time and labor costs required for installation. In particular, when it is necessary to quickly deploy or replace equipment, it can improve work efficiency.

[0068] There are many options for the structural form of the installation part, such as a support plate structure, a box structure, a frame structure, etc.

[0069] refer to Figure 2 and Figure 6 As shown, in some embodiments, the mounting portion includes a mounting frame 4 , the fan 3 is mounted in the mounting frame 4 , and the mounting frame 4 is mounted on the base plate 1 .

[0070] The frame-shaped installation frame 4 has the characteristics of large ventilation area, stable structure, light weight, etc. It can not only provide a sufficiently large air outlet and return air space for the fan 3, but also provide good support. At the same time, its lightness also makes it convenient to carry and install.

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

[0072] refer to Figure 2 As shown, in some embodiments, the air conditioner also includes a mounting plate 5 and a motor 6 for driving the fan 3, the box body also includes a top plate 7 parallel to the bottom plate 1, the mounting plate 5 is connected to the top of the mounting portion and is located above the volute of the fan 3, and the mounting plate 5 is inclined relative to the top plate 7 to form a receiving space between the top plate 7 and the mounting plate 5, and the motor 6 is mounted on the mounting plate 5 and is located in the receiving space.

[0073] The mounting plate 5 plays a role in supporting the motor 6. And through 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, which effectively utilizes the available space inside the box. Such a setting helps to reduce the volume of the air conditioner, making the overall layout of the air conditioner more compact, so that it can better adapt to complex or limited installation environments. In addition, during the transportation of the air conditioner, the fan 3 and the motor 6 can also be compactly packaged, for example, uniformly installed in the box for transportation, which can effectively save storage space, increase installed capacity, and help reduce transportation costs.

[0074] You can refer to Figure 7 , shows the layout of the fan 30a and the motor 60a in the related art. Under this layout, the motor 60a is relatively high relative to the base plate 10a, and even protrudes from the top of the box, which will significantly reduce the installed capacity during transportation and is not convenient for arranging the air duct in the effective space of the installation.

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

[0076] The mounting portion is embedded in the base plate 1, which, on the one hand, makes the combination between the base plate 1 and the mounting portion tighter and enhances the stability of the installation; on the other hand, it also helps to reduce the occupation of the mounting portion in the installation space 100a and further optimizes the space utilization efficiency in the box.

[0077] refer to Figure 8 and Fig. 9 As shown, in some embodiments, the air conditioner also includes a first bracket 8 installed on the upper surface of the base plate 1, and the first bracket 8 is provided with a first supporting surface 801 inclined relative to the upper surface of the base plate 1, and an end of the first supporting surface 801 away from the first air outlet 101 is higher than an end thereof close to the first air outlet 101, and the mounting portion is installed on the first bracket 8, and the bottom mounting plane is against the first supporting surface 801.

[0078] The first bracket 8 is used to provide stable support for the mounting portion and fix the mounting portion to the bottom plate 1. By providing a first supporting surface 801 inclined relative to the upper surface of the bottom plate 1 on the first bracket 8, the mounting portion can be installed inclined relative to the bottom plate 1. Further, by adjusting the inclination of the first supporting surface 801, the inclination of the mounting portion relative to the bottom plate 1 can be adjusted, and then the size of the first angle or the second angle can be adjusted.

[0079] refer to Figure 8 As shown, in some embodiments, the base plate 1 is provided with a mounting groove 103, and the air conditioner further includes a second bracket 10 installed in the mounting groove 103. Fig.11 As shown, the second bracket 10 is provided with a second supporting surface 1001 inclined relative to the upper surface of the base plate 1, and the end of the second supporting surface 1001 away from the first air outlet 101 is higher than the end close to the first air outlet 101, and the mounting portion is installed on the second bracket 10, and the bottom mounting plane is against the second supporting surface 1001.

[0080] The installation groove 103 provides a certain amount of space for installing the second bracket 10, which can accommodate and limit the second bracket 10, help fix the second bracket 10, and further ensure the installation stability of the installation portion. By providing a second support surface 1001 inclined relative to the upper surface of the bottom plate 1 on the second bracket 10, the installation portion can be installed inclined relative to the bottom plate 1. Further, by adjusting the inclination of the second support surface 1001, the inclination of the installation portion relative to the bottom plate 1 can be adjusted, and further the size of the first angle or the second angle can be adjusted.

[0081] Furthermore, the size and depth of the mounting groove 103 can be set so that the mounting portion can also be partially accommodated, 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 a part of the structure at 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 in the mounting space 100a, which is conducive to the layout of more other components in the mounting space 100a and improving space utilization.

[0082] In some examples where both the first bracket 8 and the second bracket 10 are provided, the inclination degrees of the first support surface 801 and the second support surface 1001 relative to the base 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 installed on the mounting portion, thereby improving the installation stability of the mounting portion and the fan 3.

[0083] In the embodiment of the present invention, there is no restriction on the number and arrangement position of the first bracket 8 or the second bracket 10. In the process of arranging and installing the mounting portion and the fan 3, the number and arrangement position of the required first bracket 8 or the second bracket 10 can be selected and adjusted according to factors such as their 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 bracket 8 or the second bracket 10 can also be adjusted according to actual needs. Figure 8 , Fig. 9 and Fig.10 As shown, the first bracket 8 and the second bracket 10 are both constructed as bent plate-shaped support structures, and their cross-sections can be square, trapezoidal, etc., to provide stable support.

[0085] refer to Fig.12 and Fig.13 As shown, in some embodiments, the bottom plate 1 includes a frame portion 1a and a cover portion 1b, and the cover 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 portion 1b. The frame structure of the frame portion 1a can provide stable support and can reserve sufficient space for installing and accommodating other related components.

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

[0087] During the installation of the air conditioner, the first bolt 14 and the second bolt 15 can be used to realize the overall installation of the mounting portion and the fan 3 on the bottom plate 1. 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 removing the first bolt 14 and the second bolt 15.

[0088] In some embodiments, reference Fig.12 As shown, the bottom plate 1 also includes a fixing portion 1c. The fixing portion 1c is connected to the space surrounded by the four beams of the frame portion 1a, and includes a plurality of baffles, which together form mounting grooves 103 for accommodating the second bracket 10 at both ends of the fixing portion 1c.

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

[0090] refer to Figure 8 As shown, in some embodiments, the air conditioner further comprises a partition plate 9, which is vertically mounted on the bottom plate 1 to separate the area above the bottom plate 1 into at least a first area and a second area, and the first air outlet 101 is located in the first area. Fig.10 As shown, a slot 802 is provided on one side of at least one first bracket 8 close to the base plate 1, and the slot 802 is constructed 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 area, and the end of the first bracket 8 close to the first air outlet 101 is located in the first area.

[0091] The partition plate 9 is used for partitioning, which is conducive to the reasonable layout of the components in the air conditioner and is convenient for maintenance and management. Alternatively, the first area and the second area can be areas respectively connected to the indoor area and the outdoor area of ​​the air conditioner. In this case, the partition plate 9 can effectively prevent rainwater or dust from the outdoor area from entering the indoor area, thereby ensuring the normal operation of the components in the indoor area.

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

[0093] Here, the evaporator 11 is vertically mounted 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] In addition, the vertical design of the evaporator 11 occupies less space, so that the installation space 100a can be efficiently utilized, thereby facilitating the arrangement of other components of the air conditioner in the installation space 100a. For example, the electrical box 12, the working fluid delivery pipeline 13, etc. Fig.15 Those skilled in the art can understand that the electrical box 12, the working fluid delivery pipeline 13 and other components are common components used in the refrigeration cycle of air conditioners or air conditioning units, and will not be described in detail here.

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

[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 port 102 or the second return air port 202, and the air further reaches the required temperature at the evaporator 11 for heat exchange, and then is sucked by the fan 3 and transported to the air outlet space 100b, and then 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 required states in different spaces, realizing efficient and stable airflow management.

[0097] Among them, air ducts can be set between the fan 3 and the first air outlet 101 and the second air outlet 201 for conveying airflow, so as to improve the conveying efficiency of the airflow.

[0098] In actual applications, different air outlet and return schemes can be selected according to user needs, such as returning air from the first return air port 102 and discharging air from the first air outlet 101, or returning air from the second return air port 202 and discharging air from the second air outlet 201, to adapt to different air supply needs or installation environments.

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

[0100] refer to Fig.16 , showing a schematic diagram of the structure of the air conditioner in some embodiments of the present invention.

[0101] It is understandable that the air conditioner may also include other components such as a condenser, an expansion valve, and an external fan for cooperating with the evaporator to realize a refrigeration cycle, which will not be described in detail here. The fan and evaporator may be installed in the indoor area of ​​the air conditioner, and the condenser, expansion valve, and external fan may be installed in the outdoor area of ​​the air conditioner, and they may be arranged reasonably according to the needs.

[0102] In the embodiment of the present invention, based on the setting that the first angle between the air outlet direction of the fan outlet of the fan and the air outlet direction of the first air outlet 101 and the second angle between the air outlet direction of the fan outlet and the second air outlet 201 are both less than 90 degrees, the air conditioner can provide different air outlet and return solutions, and the cooling or heating effects obtained by different air outlet and return solutions are similar. Users can flexibly select the air outlet direction according to their own needs to achieve different air supply requirements.

[0103] In order to further illustrate the selection of the air outlet and return air mode of the air conditioner, an air conditioner including a rooftop unit 100 is taken as an example for specific introduction.

[0104] refer to Figure 1 and Fig.16 As shown, a first air outlet 101 and a first air return outlet 102 are provided on the bottom plate 1 of the rooftop unit 100, and a second air outlet 201 and a second air return outlet 202 are provided on the side plate 2 of the box body, for a total of four air outlets.

[0105] When the rooftop unit 100 leaves the factory, the four air vents may be sealed using sheet metal.

[0106] During the installation process, if the user chooses the bottom-outlet and bottom-return solution, the sheet metal at the first air outlet 101 and the first return air outlet 102 is removed, and then the first air duct 110 and the second air duct 120 are connected, and the sheet metal at the second air outlet 201 and the second return air outlet 202 is retained. Fig.17 shown.

[0107] During the installation process, if the user chooses the side-outlet and side-return solution, the sheet metal at the second air outlet 201 and the second return air outlet 202 is removed, and the third air duct 130 and the fourth air duct 140 are connected, and the sheet metal at the first air outlet 101 and the first return air outlet 102 is retained. Fig.18 shown.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that without departing from the principles of the present invention, the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents, and these modifications and equivalent replacements should be included in the scope of the technical solution for protection of the present invention.
