[0002] As one of the most commonly used electrical appliances, air conditioners play an important role in the field of air conditioning, especially in the field of commercial large air conditioners. For super-large spaces such as office buildings and hospitals, the power of conventional household small air conditioners cannot meet the demand, and it is necessary to install large commercial air conditioners to achieve indoor air temperature regulation. Large commercial air conditioners have a large size and thus a high cost. Therefore, how to adjust the structure of commercial air conditioners to reduce the cost has been the direction of continuous improvement for manufacturers.
[0003] Correspondingly, there is a need for a new outdoor unit for an air conditioner to solve the above problems.
[0004] Application Content
[0005] The present application aims to solve the above technical problems, i.e., to solve the problem of high production cost of existing commercial air conditioners.
[0006] In a first aspect, the present application provides an outdoor unit for an air conditioner, which comprises a heat exchange unit, the heat exchange unit comprising a mounting bracket and a heat exchanger arranged in the mounting bracket; a support frame is arranged at the top of the mounting bracket, and a mounting hole is arranged on the support frame, wherein the heat exchanger is arranged in the mounting hole; a water pan is arranged at the bottom of the mounting bracket, and a guide protrusion is arranged in the water pan; and the projection area of the mounting hole in the vertical direction is greater than or equal to the area of the guide protrusion.
[0007] In a preferred embodiment of the outdoor unit for an air conditioner of the present application, the outer edge of the support frame is polygonal.
[0008] In a preferred embodiment of the outdoor unit for an air conditioner of the present application, the top of the mounting bracket is rectangular, and the polygonal support frame is arranged inside the rectangular mounting bracket.
[0009] In a preferred embodiment of the outdoor unit for an air conditioner of the present application, the outer edge of the polygonal support frame is higher than the middle part.
[0010] In a preferred embodiment of the outdoor unit for an air conditioner of the present application, the mounting hole is a circular hole, and the heat exchanger is a cylindrical heat exchanger; and / or the guide protrusion is welded in the water pan.
[0011] In the preferred embodiment of the outdoor unit for an air conditioner of the present application, the guide protrusion is arranged inside the projection of the mounting hole in the vertical direction.
[0012] In the preferred embodiment of the outdoor unit for an air conditioner of the present application, the guide protrusion is formed by the leftover material of the corner of the mounting hole.
[0013] In the preferred embodiment of the outdoor unit for an air conditioner of the present application, the inner side of the support frame is further provided with a first limiting member for fixing the heat exchanger.
[0014] In the preferred embodiment of the outdoor unit for an air conditioner of the present application, the water pan is provided with a second limiting member for fixing the heat exchanger.
[0015] The utility model also provides a kind of air conditioner, and the air conditioner includes the outdoor unit for air conditioner of above-mentioned embodiment.
[0016] As can be understood by those skilled in the art, the outdoor unit of the present application includes a heat exchange unit, which includes a mounting bracket and a heat exchanger arranged in the mounting bracket; the top of the mounting bracket is provided with a support frame, and a mounting hole is arranged on the support frame, and the heat exchanger is arranged in the mounting hole; a water pan is arranged at the bottom of the mounting bracket, and a guide protrusion is arranged in the water pan; the projection area of the mounting hole in the vertical direction is greater than or equal to the area of the guide protrusion.
[0017] In the production process of the factory, the mounting hole of the support frame is usually cut and blanked on a steel plate, and the blanking is treated and recycled as leftover material. The blanking cannot be used usually, and the waste treatment also needs cost investment. In the case of a large commercial air conditioner, the size of the blanking is not small, and it is still a considerable amount of material. If it is not used, it will lead to an increase in product cost. In the structure design of the present application, since the projection area of the mounting hole in the vertical direction is greater than or equal to the area of the guide protrusion, the size of the blanking generated from the mounting hole is greater than or equal to the size of the guide protrusion, which can be directly used for the processing and manufacturing of the guide protrusion on the water pan. In this way, the guide protrusion can be formed on the water pan, and when the outdoor rain or condensate water of the condenser falls into the water pan, it will be guided along the guide protrusion to the side of the water pan, and finally discharged or stored through the preset drain.
[0018] The present application not only utilizes waste materials, reduces waste treatment procedures, saves the cost of the support frame, and reduces the production cost of the water pan.
[0019] The polygonal support frame of the present application can combine with the mounting bracket to become multiple edges, and form multiple auxiliary triangular fixing structures.
[0020] The design of the outer edge height being higher than the middle part of the present application can form the pleated reinforcing structure, and when the exhaust fan is installed on the top of the support frame, the exhaust fan only makes sealing contact with the edge of the support frame, which is easier to seal, and the flatness requirement of the support frame is also reduced, so that the overall air leakage rate is reduced, and the processing cost is also reduced.
[0021] The present application also provides a new outdoor unit of a cylindrical heat exchanger, which further improves the heat exchange efficiency of the commercial air conditioner, reduces the overall land occupation, and reduces the overall size of the machine, thereby reducing the production cost and the installation land required by the user.
[0022] The guide protrusion is arranged inside the projection of the mounting hole in the vertical direction, which can quickly guide rainwater or condensed water to the preset position, and improve the drainage efficiency of the outdoor unit. BRIEF DESCRIPTION OF DRAWINGS

[0032] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art will understand that the embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application. Those skilled in the art can make adjustments as needed to adapt to specific application occasions. For example, although the drawings in the specification show that the outdoor unit contains eight heat exchange units as an example for description, the present application can obviously be provided with other numbers of heat exchange units, such as three, four, six, etc., and the number can be adjusted according to the actual power needs.

In addition, the terms "first", "second", "third" are only for the purpose of description and cannot be understood as indicating or implying relative importance.
[0034] In addition, it should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0035] As shown in Figures 1 to 4 The outdoor unit of the present application includes a heat exchange unit 1, which includes a mounting bracket 11 and a heat exchanger 12 arranged in the mounting bracket 11; the top of the mounting bracket 11 is provided with a support frame 111, and a mounting hole 1111 is arranged on the support frame 111, and the heat exchanger 12 is arranged in the mounting hole 1111; a water pan 112 is arranged at the bottom of the mounting bracket 11, and a guide protrusion 1121 is arranged in the water pan 112; the projection area of the mounting hole 1111 in the vertical direction is greater than or equal to the area of the guide protrusion 1121. Further, the guide protrusion 1121 is formed by cutting the corner at the mounting hole 1111.
[0036] In the production process of the factory, the mounting hole 1111 of the support frame 111 is usually cut from a steel plate, and the cut material will be treated and recycled as scrap material. The cut material usually cannot be reused, and in the case of a large commercial air conditioner, the size of the cut material is not small, and it is still a considerable amount of material. If it is not used, it will lead to an increase in product cost. In the structure of the present application, since the projection area of the mounting hole 1111 in the vertical direction is greater than or equal to the area of the guide protrusion 1121, the cut material generated from the mounting hole 1111 is larger than the size of the guide protrusion 1121, which can be directly used for the processing and manufacturing of the guide protrusion 1121 on the water pan 112. In this way, the guide protrusion 1121 can be formed on the water pan 112. When the outdoor rain or condensate water of the condenser falls into the water pan 112, it will be guided along the guide protrusion 1121 to the side of the water pan 112, and finally discharged or stored through the pre-set drain.
[0037] In addition, the conventional water pan 112 also needs a structure similar to the guide protrusion 1121. In the prior art, the water pan 112 is made by a stamping deformation process, and the bottom surface of the water pan 112 directly forms a guide structure. However, this stamping process requires a stamping machine, and increasing the stamping process will increase the production cost of the water pan 112. Especially in the field of commercial air conditioning technology, the water pan 112 is usually large, and a super large stamping machine is needed. The production cost and equipment cost are relatively high. Through the structure design of the present application, not only the waste material is utilized, the waste material treatment process is reduced, the cost of the support frame 111 is saved, but also the production cost of the water pan 112 is reduced. It can be directly obtained by welding without preparing a stamping machine, achieving two goals at once.
[0038] Further, the outer edge of the support frame 111 is polygonal, the top of the mounting bracket 11 is rectangular, the polygonal support frame 111 is arranged inside the rectangular mounting bracket 11, and the height of the outer edge of the polygonal support frame 111 is higher than the height of the middle part.
[0039] The heat exchanger 12 of the outdoor unit of the air conditioner is relatively large in size, and needs sufficient support to make it stable, so the stability of the support structure is particularly important. The outer edge of the support frame 111 is designed to be polygonal, for example Figure 4The outer edge of the support frame 111 is designed as an octagon, four edges of which can be directly attached and fixedly connected with the mounting bracket 11 of the outermost quadrilateral, and the other four edges form four triangles with the mounting bracket 11 of the quadrilateral to assist in stabilization. Compared with the conventional circular support structure, the four-point support can be changed to four-edge support, and four auxiliary triangles are formed to further stabilize, so that the top support structure is strong enough to prevent the heat exchanger 12 from tilting and deforming. Moreover, the outer edge of the polygonal support frame 111 is higher than the height of the middle part, further forming an octagonal fold, which acts as a reinforcing rib and further increases the support strength of the top. In addition, due to the large size of the top, the support frame 111 is not designed to be concave in the prior art. In actual use, due to the actual situation of large size, it is difficult to completely flatten the support frame 111 during processing. After the top exhaust fan is installed and attached and fixed, it is inevitable that the unevenness of the support frame 111 will cause air leakage at the protrusions, so that the exhaust fan cannot fully function, that is, there is air leakage. The design of the present application, in which the outer edge height is higher than the middle part, when the exhaust fan is installed on the top of the support frame 111, the exhaust fan only contacts and seals with the edge of the support frame 111, which is easier to seal, and the flatness requirement of the support frame 111 is also reduced. The overall air leakage rate is reduced, and the processing cost is also reduced, achieving two goals at once.
[0040] Further, the mounting hole 1111 is a circular hole, the heat exchanger 12 is a cylindrical heat exchanger 12, the guide protrusion 1121 is welded in the water pan 112, the guide protrusion 1121 is arranged inside the projection of the mounting hole 1111 in the vertical direction, and the inner side of the support frame 111 is further provided with a first limiting member 1112 for fixing the heat exchanger 12, and the water pan 112 is provided with a second limiting member 1122 for fixing the heat exchanger 12.
[0041] In the prior art, the heat exchanger of the outdoor unit of a large commercial air conditioner is usually CV-shaped or V-shaped. Such air conditioners are already conventional prior art. For example, a CV-shaped air conditioner has a heat exchanger inside the outdoor unit that is similar to an inverted truncated cone, and the longitudinal section thereof is an inverted trapezoid. For another example, a V-shaped heat exchanger has a heat exchanger inside the outdoor unit that is similar to an inverted cone, and the longitudinal section thereof is V-shaped. The overall heat exchange effect of these two types of air conditioners is acceptable, and they have been widely used. However, the heat exchange efficiency still has room for improvement. Based on this, the applicant proposes a new outdoor unit for an air conditioner, which changes the conventional CV-shaped or V-shaped design and proposes a new heat exchanger 12. The heat exchanger 12 is changed to a cylindrical shape, i.e., a cylindrical heat exchanger 12, and the longitudinal section thereof is a rectangle. Compared with the heat exchanger of the conventional structure, the heat exchange efficiency of this heat exchanger is better, which exceeds the original CV-shaped or V-shaped heat exchanger, further improves the heat exchange efficiency of the commercial air conditioner, and after the cylindrical heat exchanger 12 is used, the spacing between the adjacent two groups of heat exchange units 1 at the optimal heat exchange efficiency becomes smaller, thereby reducing the overall floor area of the outdoor unit, and the reduction in the overall size of the machine also reduces the production cost, and the user needs to provide less installation land.
[0042] The guide protrusion 1121 is arranged inside the projection of the mounting hole 1111 in the vertical direction, so that the guide protrusion 1121 can face the circular mounting hole 1111 directly. When it is raining outside, the rainwater outside falls into the water pan 112 through the circular mounting hole 1111 and directly falls on the guide protrusion 1121, and then quickly guides to the preset position. Compared with the scheme without being arranged inside the projection or the scheme partially arranged inside the projection, the technical scheme of the present application has faster guiding speed and better drainage effect.
[0043] In order to further realize the stable fixation of the heat exchanger 12, as shown in Figure 3 , Figure 4 The first limiting member 1112 is designed on the inner side of the support frame 111, and the second limiting member 1122 is arranged in the water pan 112, so that the heat exchanger 12 can be completely fixed and not moved, and the overall strength of the outdoor unit is higher.
[0044] In summary, by the structural design of the present application, not only the waste material is utilized, the waste material processing procedure is reduced, the cost of the support frame 111 is saved, and the production cost of the water pan 112 is also reduced. The polygonal support frame 111 can be combined with the mounting bracket 11 to become multiple edges in length, and multiple auxiliary triangular fixing structures are formed. The design of the outer edge height being higher than the middle part of the present application forms the wrinkled reinforcing structure, and when the exhaust fan is installed on the top of the support frame 111, the exhaust fan only seals and contacts the edge of the support frame 111, which is easier to seal, and the flatness requirement of the support frame 111 is also reduced. The overall air leakage rate is reduced, and the processing cost is also reduced. The present application also provides a new cylindrical heat exchanger 12 outdoor unit, which further improves the heat exchange efficiency of the commercial air conditioner, reduces the overall land area, and reduces the size of the whole machine, which also reduces the production cost, and the user needs to provide less installation land. The guide protrusion 1121 is arranged inside the projection of the mounting hole 1111 in the vertical direction, which can quickly guide the rainwater or condensed water to the preset position, and strengthen the drainage efficiency of the outdoor unit.
[0045] In addition, the present application also provides an air conditioner, which has the outdoor unit for the air conditioner described in any of the above embodiments.
[0046] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will all fall within the protection scope of the present application.
