In addition, the fixing method between the upper plate of the motor housing and the middle pump housing (Fig. 1) is also to extend a plurality of lugs (Fig. 21) outward from the motor housing, and a plurality of take-up parts (Fig. 12) outward from the pump housing, and bolts are passed through the lugs to lock the take-up parts, thereby fixing the motor to the pump housing.

[0004] Japanese Patent No. 5934515 also discloses a drainage pump for air conditioning devices, the overall shell of which is a housing for a motor and some motor components, and the motor (Figure 60) is accommodated in the upper part of the housing, and the motor components (drive shaft (Figure 110) and water baffle (Figure 30)) are accommodated in the middle part of the housing. This case has three fixing feet on the top edge of the housing, which can be used to install on the air conditioning device. In addition, the case Figure 4 It can be seen that the motor housing is also provided with a convex portion to be combined with the access hole of the shell.

[0005] It can be seen from the above-mentioned prior art that when setting the fixing feet on the drain pump, it is also necessary to consider the configuration relationship of the motor set on the top of the shell, so there are the above-mentioned different implementation methods. Summary of the invention

[0006] In the above-mentioned prior art, if the fixing foot is set on the cover at the top of the housing or on the top of the motor housing, the lower housing is connected to the upper cover or motor housing by a connecting piece, so the overall structure will be loose, and it is easier to generate noise or vibration during operation due to the assembly gap. In the above-mentioned prior art, if the fixing foot is set on the housing, there is a problem of matching the protrusion and the access hole when the motor housing and the housing are assembled.

[0007] The present invention provides a drainage pump for an air conditioner with a mounting structure, wherein the fixing feet are arranged on the main housing and there is no problem of assembling the motor housing and the housing, which is different from the current prior art in structure.

[0008] In order to solve the above problems, the present invention proposes a drainage pump for an air conditioner with an installation structure, comprising: a lower shell, a water suction port formed at the bottom, and a drainage port formed on the side; a main shell, which is cylindrical and arranged above the lower shell, and a drainage chamber is formed between the main shell and the lower shell, the water suction port and the drainage port are both spatially connected to the drainage chamber, and the main shell has a motor chamber and an overflow chamber; a drainage blade is arranged in the drainage chamber, a motor is arranged in the motor chamber, the overflow chamber is located below the motor chamber, and the bottom has a through hole and The main housing is spatially connected to the drainage chamber, and the drainage blade is connected to the driving shaft of the motor through the through hole; and a cover body is covered on the main housing to cover the motor housing; the outer circumference of the main housing is upward and a plurality of fixing legs extend obliquely outward, and some of the fixing legs are fixed to the outer circumference of the main housing, and the rest are higher than the top of the main housing by a predetermined length, each of the fixing legs has a plate-shaped body and two reinforcing ribs located on both sides of the plate-shaped body, and the two reinforcing ribs of each of the fixing legs are parallel to each other; each of the fixing legs has a platform on the top, and the platform has a fixing hole.

[0009] Wherein: the plate-shaped body of each of the fixing legs is formed integrally with the main shell body, and extends obliquely upward and outward from the bottom of the outer peripheral surface of the main shell body.

[0010] Among them: in the interval from the bottom to the top of the outer peripheral surface of the main shell, the plate-like body of each fixing foot gradually becomes thicker from the bottom to the top; in the part higher than the top of the main shell, the thickness of the plate-like body of each fixing foot is the same from bottom to top.

[0011] Wherein: the thickness of the two reinforcing ribs of each of the fixing legs gradually increases upward along the bottom end of the surface of the plate-shaped body, and the plate surface of the plate-shaped body is lower than the surface of the two reinforcing ribs.

[0012] The cover body has a plurality of hooks extending outward and downward, and a plurality of clamping blocks are arranged on the outer surface of the main shell body. The cover body is fixed to the main shell body by the plurality of hooks hooking the plurality of clamping blocks.

[0013] Wherein: the range enclosed by the plate-shaped body of the plurality of fixing legs at the top of the main shell is larger than the cover body, and when the cover body is covered on the main shell, the plurality of fixing legs do not interfere with the cover body.

[0014] Wherein: the plurality of fixing legs do not interfere with the top edge of the main shell, and the cover body covers the top edge of the main shell.

[0035] In order to explain the technical features of the present invention in detail, the following preferred embodiments are given and described with reference to the accompanying drawings, wherein:

[0036] like Figures 1 to 6 As shown, a drainage pump 10 for an air conditioner with an installation structure provided by a preferred embodiment of the present invention is mainly composed of a lower shell 11, a main shell 21 and a cover 31, wherein:

[0037] The lower shell 11 has a water inlet 12 formed at the bottom and a water outlet 14 formed at the side.

[0038] The main housing 21 is cylindrical and is disposed above the lower housing 11. A drainage chamber 18 is formed between the main housing 21 and the lower housing 11. The water inlet 12 and the drainage port 14 are both connected to the drainage chamber 18 in space. The main housing 21 has a motor chamber 22 and an overflow chamber 24. A drainage blade 19 is disposed in the drainage chamber 18. A motor 23 is disposed in the motor chamber 22. The overflow chamber 24 is located below the motor chamber 22. The main housing 21 has a plurality of overflow holes 241 on the side of the overflow chamber 24 for the water in the overflow chamber 24 to be discharged outward. The bottom of the main housing 21 has a through hole 26 that is connected to the drainage chamber 18 in space. The drainage blade 19 is connected to the driving shaft of the motor 23 through the through hole 26. The outer surface of the main housing 21 is provided with a plurality of blocks 28.

[0039] The cover 31 is disposed on the main housing 21 to cover the motor housing 22. In this embodiment, the cover 31 extends outward and downward to form a plurality of hooks 38, and the cover 31 is fixed to the main housing 21 by hooking the plurality of blocks 28 with the plurality of hooks 38. In this embodiment, the number of the plurality of hooks 38 is three.

[0040] Among them, the outer circumference of the main shell 21 extends upward and outward obliquely three fixing legs 29, and the three fixing legs 29 are partially fixed to the outer circumference of the main shell 21, and the rest of the three fixing legs 29 are higher than the top of the main shell 21 by a predetermined length. Each of the fixing legs 29 has a plate-shaped body 291 and two reinforcing ribs 292 respectively located on both sides of the plate-shaped body 291, and the two reinforcing ribs 292 of each of the fixing legs 29 are parallel to each other. In addition, each of the fixing legs 29 has a platform 294 on the top, and the platform 294 has a fixing hole 295, and the fixing hole 295 can be passed through by a bolt 99 to lock the platform 294 on an air conditioning device 91. The three hooks 38 and the three fixing legs 29 are arranged alternately, and one of the hooks 38 is located between two of the fixing legs 29, and one of the fixing legs 29 is located between the two hooks 38. The aforementioned fixing legs 29 are three in number for example. In actual implementation, the number can also be two or four as needed, and is not limited to three.

[0041] In actual implementation, the three aforementioned fixing legs 29 are integrally formed with the main shell 21, that is, the plate-like body 291 and the reinforcing ribs 292 of each fixing leg 29 are integrally formed with the main shell 21. Moreover, the plate-like body 291 of each fixing leg 29 extends obliquely upward and outward from the bottom of the outer circumference of the main shell 21. It can be seen from the various figures of this case that each fixing leg 29 mainly extends upward and is slightly inclined outward. In the interval from the bottom to the top of the outer circumference of the main shell 21, the plate-like body 291 of each fixing leg 29 gradually thickens from the bottom to the top. The thickness here refers to the thickness increased radially outward from the outer circumference of the main shell 21 as the bottom. Its state can be referred to. Figure 6 In the portion above the top of the main housing 21, the thickness of the plate-shaped body 291 of each fixing leg 29 is the same from bottom to top. The thickness of the two reinforcing ribs 292 of each fixing leg 29 gradually increases upward along the bottom of the surface of the plate-shaped body 291, and the plate surface of the plate-shaped body 291 is lower than the surface of the two reinforcing ribs 292.

[0042] In addition, the three fixing legs 29 do not interfere with the top edge of the main shell 21, and the range enclosed by the plate-shaped body 291 of the three fixing legs 29 at the top of the main shell 21 is larger than the cover body 31. Therefore, when the cover body 31 is covered on the main shell 21, it can directly cover the top edge of the main shell 21 without being interfered by the three fixing legs 29, thereby making the assembly of the cover body 31 and the main shell 21 easier.

[0043] The above describes the architecture of this embodiment. Next, the usage of this embodiment will be described.

[0044] See also Figure 7 Cooperate Figure 6 As shown, before use, the present invention is installed on an air conditioning device 91, and is mainly locked on the air conditioning device 91 by passing a plurality of bolts 99 through the fixing holes 295 of the three fixing legs 29. When in use, since the three fixing legs 29 of the present invention extend upward from the bottom of the outer peripheral surface of the main housing 21, the three fixing legs 29 being fixed are equivalent to directly pulling the main housing 21, and the fixing effect formed is more stable than the structure in the prior art where the fixing legs are arranged on the cover body, and the structure where the three fixing legs 29 extend upward from the bottom of the main housing 21 is equivalent to the bottom of the main housing 21 being fixed by the three fixing legs 29, so it can provide a better fixing effect than the current prior art. In addition, since the three fixed legs 29 have a predetermined length at the top of the main shell 21, the main shell 21 is suspended below the air-conditioning device 91. When the motor 23 is running, the vibration generated by the rotation of the drainage blades 19 can be absorbed by the suspension relationship of the three fixed legs 29, thereby reducing vibration and noise.

[0045] In addition, since there is no connection between the three fixing feet 29 and the cover body 31, and only the cover body 31 is directly covered with the main shell 21, the motor 23 only needs to be directly placed in the motor chamber 22 in the main shell 21, and then the cover body 31 is covered to complete the assembly of the motor 23. There is no need to consider the assembly problem between the motor housing and the shell in the prior art, which also solves the problems of the aforementioned prior art.

[0046] In summary, the fixing foot 29 of the present invention is disposed on the main housing 21, rather than on the cover 31, thus solving the problem of loose structure caused by the fixing foot disposed on the cover in the prior art. In addition, the present invention disposes the fixing foot 29 on the main housing 21, so that the cover 31 can be covered on the main housing 21 without interfering with the fixing foot 29, thus eliminating the problem of motor housing installation in the prior art, and solving the problem of assembly between the motor housing and the housing in the prior art, which has an improvement in function and is different in structure from the current prior art.

[0047] It should be added that if Figure 3 As shown, the lower housing 11 and the main housing 21 are fixed by a plurality of bolts 99. Figure 8 As shown, the lower housing 11 and the main housing 21 can also be hooked and fixed together by a combination of a plurality of hooks 118 and clamping blocks 28 .

[0048] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims of the present invention.
