Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioners, and in particular to an outdoor unit and an air conditioning unit. BACKGROUND

[0002] Different models of air conditioning units have different capacities and weights. For a traditional small-capacity unit, the unit itself is light in weight. The support mode of the small-capacity unit is to install two supporting legs at the bottom of the base. The weight of a super-large-capacity, super-large-weight unit is several times that of a small-capacity unit, so the support mode of the small-capacity unit cannot meet the support requirements of the super-large-capacity, super-large-weight unit.

[0003] The present application relates to the field of air conditioners, and in particular to an outdoor unit and an air conditioning unit. SUMMARY

[0038] The following is combined with Figures 1-6 The technical solution provided by this invention will be described in more detail below.

[0039] See Figure 1The outdoor unit provided by the embodiment of the present application comprises a compressor 1, a heat exchanger 2, a bottom plate 3 and a foot assembly 4. The heat exchanger 2 is communicated with the compressor 1. The bottom plate 3 supports the compressor 1 and the heat exchanger 2. The foot assembly 4 is fixed to the bottom of the bottom plate 3. At least three foot assemblies 4 are distributed along the length direction of the bottom plate 3.

[0040] The compressor 1 is used for compressing refrigerant. The height dimension of the compressor 1 is smaller than the height dimension of the heat exchanger 2, and the length dimension of the bottom plate 3 occupied by the compressor 1 is also smaller than the length dimension occupied by the heat exchanger 2.

[0041] The foot assembly 4 is fixed to the bottom of the bottom plate 3 by bolt connection. If the point welding is used for connection and fixation, the material properties of the bottom plate 3 and the foot assembly 4 at the point welding position will be changed, so that the strength at the point welding position is weakened. For the super large capacity and super large weight unit targeted by the present technical solution, the strength weakening caused by the point welding position is very obvious, which makes it difficult to meet the use requirement of the support strength at the connection position of the bottom plate 3 and the foot assembly 4, and there is a risk of fracture at the connection position of the bottom plate 3 and the foot assembly 4.

[0042] The bolt connection provided by the embodiment of the present application is mainly used for connecting the screw itself, and the bolt will not change the material properties of the bottom plate 3 and the foot assembly 4, so that the reliability and strength of the bolt connection are higher than those of the point welding connection.

[0043] In some embodiments, at least two foot assemblies 4 are installed at the bottom of the region of the bottom plate 3 corresponding to the heat exchanger 2. In some embodiments, at least one foot assembly 4 is installed at the bottom of the region of the bottom plate 3 corresponding to the compressor 1.

[0044] Specifically, two foot assemblies 4, i.e. the first foot assembly 4a and the second foot assembly 4b introduced hereinafter, are arranged in the lower region of the bottom plate 3 occupied by the heat exchanger 2. One foot assembly 4, i.e. the third foot assembly 4c, is arranged in the lower region of the bottom plate 3 occupied by the compressor 1.

[0045] Referring to Figure 1 The bottom of the compressor 1 is provided with a plurality of support portions which are dispersedly arranged along the circumferential direction of the compressor 1. The plurality of support portions jointly bear the weight of the compressor 1 and stably fix the compressor 1 to the top of the bottom plate 3. A buffer pad can be arranged between each support portion and the compressor 1 to reduce the impact force received by the compressor 1 during transportation and operation.

[0046] In Figure 1In the shown embodiment, the compressor 1 is located at one side of the chassis 3 in the length direction, and the heat exchanger 2 is located at the other side of the chassis 3 in the length direction. The compressor 1 and the chassis 3 are detachably fixedly connected, and the heat exchanger 2 and the chassis 3 are also detachably fixedly connected, which can be achieved by using bolts and other components.

[0047] Referring to Figure 2 and Figure 3 , the length direction of each foot assembly 4 is perpendicular to the length direction of the chassis 3. This supporting manner plays a supporting role at multiple positions of the chassis 3 in the length direction, so that the supporting effect of the foot assembly 4 is more balanced.

[0048] Referring to Figure 2 and Figure 3 , in some embodiments, the length dimension L of the foot assembly 4 is greater than the width dimension W of the chassis 3, and both ends of the foot assembly 4 are located outside the chassis 3. Specifically, in the width direction of the chassis 3, the length of the two parts of the foot assembly 4 located outside the chassis 3 is the same. In this way, the structure of the entire outdoor unit is more symmetrical and stable, and the load bearing of the foot assembly 4 in its length direction is more balanced.

[0049] As introduced above, the number of foot assemblies 4 is three: the first foot assembly 4a, the second foot assembly 4b, and the third foot assembly 4c. The second foot assembly 4b is located between the first foot assembly 4a and the third foot assembly 4c. The distance between the first foot assembly 4a and the side edge of the chassis 3 is the first distance A, the distance between the first foot assembly 4a and the second foot assembly 4b is the second distance B, the distance between the second foot assembly 4b and the third foot assembly 4c is the third distance C, and the distance between the third foot assembly 4c and the other side edge of the chassis 3 is the fourth distance D. Among them, A:B:C:D = 1:2.8~3.3:1~1.5:1.

[0050] Specifically, A:B:C:D = 1:3:1.3:1.

[0051] The use of the above ratio makes the maximum deformation area of the chassis 3 smaller than that in the prior art, and the maximum deformation Max is relatively small, effectively improving the strength and reliability of the chassis 3 during transportation and operation.

[0052] For comparison Figure 4 , Figure 5 and Figure 6 , among them, Figure 4 is the load simulation effect of the ratio range defined by the above embodiments of the present application, Figure 5 is a comparison effect diagram using A:B:C:D = 1:2.7:1.5:1, Figure 6For the contrast effect diagram, A:B:C:D = 1:3.4:0.9:1.

[0053] wherein, Figure 4 The maximum deformation region is marked as Max1, and the maximum deformation amount is marked as U1. Figure 5 The maximum deformation region is marked as Max2, and the maximum deformation amount is marked as U2. Figure 6 The maximum deformation region is marked as Max3, and the maximum deformation amount is marked as U3.

[0054] Figure 5 In the embodiment, when the size ratio (A:B:C:D) of the first distance A, the second distance B, the third distance C, and the fourth distance D is 1:2.7:1.6:1, the size of the maximum deformation region Max2 is obviously larger than that of the maximum deformation region Max1 with the size ratio (A:B:C:D) of 1:3:1.3:1, and the ratio is Max1=0.125*Max2. In addition, U1=0.8*U2. It can be seen that when the ratio range provided by the embodiment is used, the overall deformation region of the chassis is smaller, the deformation amount is smaller, the overall strength of the chassis of the unit is stronger, and the reliability is better.

[0055] Figure 6 In the embodiment, when the size ratio (A:B:C:D) of the first distance A, the second distance B, the third distance C, and the fourth distance D is 1:2.7:1.6:1, the size of the maximum deformation region Max2 is obviously larger than that of the maximum deformation region Max1 with the size ratio (A:B:C:D) of 1:3:1.3:1, and the ratio is Max1=0.125*Max2. In addition, U1=0.8*U2. It can be seen that when the ratio range provided by the embodiment is used, the overall deformation region of the chassis is smaller, the deformation amount is smaller, the overall strength of the chassis of the unit is stronger, and the reliability is better.

[0056] If the technical solution provided by the embodiment is compared with the solution with only two legs, the technical effect of the embodiment is better. The maximum deformation region of the technical solution provided by the embodiment is about 0.6 times that of the two-leg solution, and the maximum deformation amount is about 0.25 times that of the two-leg solution.

[0057] In some embodiments, the first distance is 180mm-220mm. Taking the first distance of 200mm as an example, the second distance is 600mm, the third distance is 260mm, and the fourth distance is 200mm.

[0058] In some embodiments, the center of gravity of the outdoor unit is located between the first leg assembly 4a and the second leg assembly 4b. The first leg assembly 4a and the second leg assembly 4b are specifically located in the region of the corresponding chassis 3 below the heat exchanger 2.

[0059] The position of the center of gravity of the outdoor unit corresponds to the area of the chassis 3 where the deformation is the largest. In the embodiment of the present application, the first leg assembly 4a and the second leg assembly 4b are arranged in the above-mentioned manner, which can effectively enhance the supporting effect on the heat exchanger 2.

[0060] Referring to Figure 2 and Figure 3 , the third leg assembly 4c is located below the compressor 1 and corresponds to the area of the chassis 3. Most of the weight (the compressor 1, oil, gas, pipelines, etc.) of the air conditioning unit is arranged on the right side of the chassis 3 (for example, the left and right directions shown in Figure 1 and Figure 2 ), so the third leg assembly 4c is placed below the right weight center of gravity, that is, below the compressor 1.

[0061] Referring to Figure 3 , each leg assembly 4 can adopt the same structure. Each leg assembly 4 specifically includes a support plate 41, a support frame 42, and a reinforcing plate 43. The support plate 41 is fixedly connected with the chassis 3 and is in surface-to-surface contact, which can be full surface-to-surface contact or partial surface-to-surface contact. The support frame 42 is fixed to the side of the support plate 41 away from the chassis 3. The reinforcing plate 43 is fixed to the inside of the support frame 42 to increase the strength of the support frame 42.

[0062] The shape of the support plate 41 matches the shape of the bottom surface of the chassis 3 to form more surface-to-surface support. The shape of the support plate 41 is generally rectangular. The support frame 42 is a generally rectangular frame, and the support frame 42 is fixedly connected with the support plate 41 or integrally formed. The reinforcing plate 43 plays a role in reinforcing support, and the reinforcing plate 43 can be fixedly connected with the support frame 42 and the support plate 41.

[0063] The height of each leg assembly 4 is relatively low, and only needs to lift the chassis 3 away from the ground, without the need to lift it relatively high. This makes the center of gravity of the entire outdoor unit relatively low, which is beneficial to improve the stability of the outdoor unit during transportation and use.

[0064] The embodiment of the present application also provides an air conditioning unit, which includes the outdoor unit provided by any of the technical solutions of the present application.
