Technical Field

The invention relates to the technical field of air conditioners, in particular to a chassis assembly for an air conditioner, the air conditioner and a motor home.

Background

With the continuous improvement of living standard, the requirements of people on living environment are higher and higher. In order to obtain a comfortable temperature and humidity environment, an air conditioner has become one of essential devices in human life. According to the difference of the structure, the air conditioner can be divided into an integrated air conditioner and a split air conditioner. Among them, the integrated air conditioner is to arrange functional components such as a compressor, a condenser, an expansion device, and an evaporator in a single housing. The split type air conditioner includes an indoor unit and an outdoor unit spaced apart from each other, an indoor heat exchanger and an indoor fan associated therewith being disposed in the indoor unit, and a compressor, an outdoor heat exchanger, an outdoor fan, an expansion device, and the like being disposed in the outdoor unit.

The compressor is a core component of both the integrated air conditioner and the split air conditioner. The compressor is typically fixed to the chassis. The chassis can be the chassis of the shell of the integrated air conditioner, and can also be the chassis of the shell of the outdoor unit of the split air conditioner. When the integrated air conditioner or outdoor unit is transported or falls for a long time, the chassis is easily deformed under the influence of the gravity of the compressor, so that the stability of the shell is affected. When the chassis is seriously deformed, the compressor is easily damaged, and the normal operation of the air conditioner is greatly influenced.

Therefore, there is a need in the art for a new solution to the above-mentioned problems.

In one or more embodiments, the air conditioner 1 further includes a four-way valve (not shown in the figure) capable of controlling the direction change of the refrigerant medium, so that the air conditioner 1 can perform cooling and heating according to actual needs.

With continued reference to FIG. 1, in one or more embodiments, the compressor 11 is a rotary compressor. Alternatively, the compressor 11 may be a reciprocating compressor, an axial compressor, a centrifugal compressor, or other suitable compressor. In one or more embodiments, 3 mounting feet 111 are formed at the bottom of the compressor 11, evenly spaced from each other. Each mounting foot 111 is configured to be secured to the chassis assembly 2 by suitable fasteners (e.g., bolts, nuts, etc.). Alternatively, the number of the mounting feet 111 may be set to other suitable numbers more or less than 3, such as 2, 4, etc.

An embodiment of the base plate assembly 2 for the air conditioner 1 of the present invention will be described in detail with reference to fig. 1 to 11.

As shown in fig. 1, in one or more embodiments, the chassis assembly 2 includes a chassis 20, a back plate 30, and diagonal draw bars 40. The base plate 20 is used for mounting the compressor 11 and the like. A back panel 30 is secured to the rear of the chassis 20 for covering and protecting the components. In one or more embodiments, the diagonal draw bars 40 include a left diagonal draw bar 40a and a right diagonal draw bar 40b located on the left side and the right side of the chassis 20, respectively. In one or more embodiments, the left and right

diagonal braces

40a and 40b are symmetrically arranged with respect to the chassis 20 such that the chassis 20 is more evenly stressed. Each of the left and right

diagonal draw bars

40a, 40b has opposite upper and lower ends. Wherein the lower end is connected to the chassis 20 and the upper end is connected to the back plate 30. Alternatively, the diagonal member 40 may include only one of the left diagonal member 40a and the right diagonal member 40b, for example, only the left diagonal member 40a or only the right diagonal member 40b.

FIG. 6 is a schematic front view of an embodiment of a base pan assembly for an air conditioner of the present invention; fig. 7 is a rear view schematically illustrating the construction of an embodiment of a base pan of the base pan assembly for an air conditioner according to the present invention; fig. 8 is a partial enlarged view of part C of the embodiment of the base pan assembly for an air conditioner of the present invention shown in fig. 7. As shown in fig. 6-8, in one or more embodiments, the chassis 20 includes a chassis body 21 and a chassis flange 22 formed on the chassis body 21. The chassis body 21 and the chassis flange 22 may be manufactured by a machining process using a suitable metal material (e.g., stainless steel, etc.). The chassis body 21 has a substantially rectangular plate-like structure to provide a suitable installation space and strong support for mounting the compressor 11, a heat exchanger (not shown), a heat exchanger fan (not shown), and the like.

With continued reference to FIG. 6, in one or more embodiments, 3 mounting projections 211 are provided on the right side of the chassis body 21, spaced apart from one another. Alternatively, the mounting projection 211 may be provided on the left side of the chassis body 21 or other suitable position. Each of the mounting projections 211 is configured to extend vertically upward from the chassis body 21. The mounting protrusion 211 may be formed by a stamping process. A corresponding mounting hole 2112 is also provided in each mounting boss 211 for mating with a suitable fastener (e.g., bolt, nut, etc.) to securely fasten the mounting foot 111 of the compressor 11 to the chassis body 21. Alternatively, the number of the mounting projections 211 may be set to other suitable number more or less than 3, for example, 2, 4, etc., as long as it can be fitted with the mounting base 111 of the compressor 11. The installation of the installation protrusion 211 can enhance the strength of the region of the chassis body 21 for installing the compressor 11, and ensure the installation reliability of the compressor 11. It should be noted that, during long-term transportation or use of the air conditioner 1, the chassis body 21 is easily deformed under the influence of gravity of the compressor 11 because the weight of the compressor 11 is heavy. The installation of the installation protrusion 211 can effectively improve the bending resistance of the chassis body 21 in the region where the compressor 11 is installed, and prevent the deformation. In one or more embodiments, a reinforcing mounting protrusion 2111 extending vertically upward is also provided on the mounting protrusion 211, and a mounting hole 2112 is provided on the reinforcing mounting protrusion 2111. With the above arrangement, the strength and the bending resistance of the chassis body 21 can be further improved.

With continued reference to FIG. 6, in one or more embodiments, 1 bracket mounting boss 212 is provided at the middle of the chassis body 21. The bracket mounting projection 212 is configured to extend vertically upward from the chassis body 21. The bracket mounting boss 212 may be formed by a stamping process. Bracket mounting holes 2121 are formed in the bracket mounting bosses 212 to mate with suitable fasteners (e.g., bolts, nuts, etc.) to secure the bracket 50 (see fig. 1) to the chassis body 21. The bracket mounting protrusion 212 can enhance the structural strength of the chassis body 21, and prevent the chassis body 21 from being deformed due to a large pressure applied to the region where the bracket 50 is mounted. In one or more embodiments, a reinforcing bracket mounting boss 2122 is also formed on the bracket mounting boss 212 to extend vertically upward to further enhance the structural strength and bending resistance of the chassis body 211 in the area of the mounting bracket 50.

With continued reference to fig. 6, in one or more embodiments, 4 support projections 213 are provided spaced apart from one another at a location proximate to the circumferential edge at the rear of the chassis body 21. Each of the support protrusions 213 is configured to extend vertically upward from the chassis body 21. The support protrusions 213 may be formed using a stamping process. Each support protrusion 213 is configured to abut against the backplate flange 32 of the backplate 30 to support the backplate 30. The support protrusion 213 can reduce the contact area between the base plate 20 and the back plate 30, and prevent the compressor 11 from generating large vibration and noise during operation. Alternatively, the number of the support protrusions 213 may be set to other suitable numbers more or less than 4, such as 3, 5, and the like.

With continued reference to fig. 6-8, in one or more embodiments, symmetrically disposed restraining protrusions 214 are formed on the left and right sides of the chassis body 21, respectively. The stopper projection 214 is positioned near the circumferential edge of the chassis body 21 and is configured to extend vertically upward from the chassis body 21. That is, the lower surface 215 of the chassis body 21 is the lower surface of the restricting projection 214. The position-limiting protrusion 214 may be formed by a stamping process. The arrangement of the limiting protrusion 214 can enhance the structural strength and bending resistance of the joint of the chassis body 21 and the diagonal draw bar 40. In addition, the limiting protrusion 214 may also be provided to form a limiting cavity 2141 on the downward-facing lower surface 215 of the chassis body 21 for receiving the lower mounting plate 43 of the diagonal member 40, so as to improve the assembly efficiency and the assembly accuracy of the lower mounting plate 43. That is, the downwardly facing lower surface of the stopper protrusion 214 forms the bottom surface of the stopper cavity 2141. In one or more embodiments, a generally rectangular through hole 2142 is formed on the restriction protrusion 214, and a positioning flange 2143 vertically extending downward from the restriction protrusion 214 is formed on one edge of the through hole 2142. During assembly, the positioning flange 2143 can be easily abutted against the lower mounting plate 43, thereby further improving the assembly efficiency and the assembly accuracy of the lower mounting plate 43. Alternatively, the positioning flange 2143 may take other suitable configurations, such as being welded directly to the lower surface of the retention tab 214.

As shown in fig. 6, in one or more embodiments, the chassis flange 22 is configured to extend vertically upward along the peripheral edge of the chassis body 21 to enhance the structural strength and bending resistance of the chassis body 21, and also to facilitate forming a fixed connection with the diagonal draw bars 40. Chassis coupling grooves 221 for mounting the left and right

diagonal members

40a and 40b are formed on both left and right sides of the chassis flange 22, respectively. As shown in fig. 8, the chassis connecting groove 221 is formed by bending the chassis flange 22 inward, so that the diagonal member body 41 of the diagonal member 40 can be conveniently abutted against the chassis connecting groove 221, thereby facilitating the positioning and installation of the diagonal member 40. On the chassis coupling groove 221 are formed 2 chassis coupling holes 2211 arranged spaced apart from each other. Each chassis attachment hole 2211 has a substantially regular hexagonal shape. Alternatively, the chassis attachment holes 2211 may be provided in a circular or other suitable shape. Each chassis attachment hole 2211 may be fitted with suitable fasteners (e.g., bolts, nuts, etc.) to secure the diagonal draw bar 40 to the chassis flange 22. Alternatively, the number of chassis attachment holes 2211 may be provided in other suitable numbers, such as 1, 3, etc., more or less than 2.

With continued reference to FIG. 6, in one or more embodiments, a reinforcement flange 222 is also provided forward of the chassis flange 22. The reinforcing flange 222 is formed at a position close to the compressor 11 and is configured to extend vertically upward (toward a direction away from the chassis body 21) from the chassis flange 22. In other words, the height of the pan flange 22 (i.e., the reinforcement flange 222) near the compressor 11 is higher than the pan flange 22 at other positions. With the above arrangement, the structural strength and bending resistance of the pan flange 22 in the region near the compressor 11 can be further enhanced.

With continued reference to FIG. 6, in one or more embodiments, 4 back plate securing holes 223 are formed in the rear portion of the chassis flange 22, evenly spaced from one another. Each of the back plate fixing holes 223 has a substantially circular shape. Alternatively, the back plate fixing holes 223 may be provided in a regular hexagon or other suitable shape. Each back plate securing aperture 223 is configured to mate with a suitable fastener (e.g., bolt, nut, etc.) such that the chassis flange 22 conveniently forms a secure connection with the back plate 30. Alternatively, the number of the back plate fixing holes 223 may be set to other suitable numbers more or less than 4, such as 3, 5, etc. In one or more embodiments, each back plate fixing hole 223 is positioned above the corresponding support protrusion 213, so that the support protrusion 213 can correspondingly enhance the structural strength of the chassis flange 22, and weaken the effect of the strength reduction caused by the opening of the through hole on the chassis flange 22.

Fig. 9 is a rear view showing the structure of the back panel of the base plate assembly for an air conditioner according to the embodiment of the present invention. As shown in FIG. 9, in one or more embodiments, the backplate 30 includes a backplate body 31 and a backplate flange 32 formed on the backplate body 31. The backplate body 31 and the backplate flange 32 may be manufactured by a machining process using a suitable metal material (e.g., stainless steel, etc.). The back plate body 31 has a substantially rectangular plate-like structure. Based on the orientation shown in fig. 1, the backplate flange 32 is configured to extend perpendicularly from the peripheral edge of the backplate body 31 toward the front of the chassis 20. As shown in fig. 1, in the assembled state, the back plate 30 is fixed to the rear of the chassis 20, and the back plate body 31 is substantially perpendicular to the chassis body 21. The backplate flange 32 abuts against the chassis body 21. In one or more embodiments, the backplate flange 32 abuts against the support protrusions 213 of the backplate body 21 to prevent the compressor 111 fixed to the backplate body 21 from generating large vibration and noise during operation.

With continued reference to FIG. 9, in one or more embodiments, a grill (not identified) having vent holes is formed on the back plate body 31. The grill is positioned to be opposite to the heat exchanger installed on the base plate body 21 so that the heat exchanger can conveniently exchange heat with the external environment, improving the heat exchange efficiency of the air conditioner 1.

With continued reference to FIG. 9, in one or more embodiments, 2 bracket mounts 312 for securing the bracket 50 are also provided at the middle of the back plate body 31. The 2 bracket mounts 312 are spaced apart from each other in the up-down direction. At each bracket mounting portion 312, 3 fixing holes (not shown) are formed to be spaced apart from each other. Each of the fixing holes 313 is configured to mate with a suitable fastener (e.g., a bolt, a screw, etc.) to secure the backplate mounting portion 52 of the bracket 50 to the backplate body 31. Alternatively, the fixing holes may be provided in other suitable numbers, such as 2, 4, etc., more or less than 3.

With continued reference to fig. 9, in one or more embodiments, 4 chassis fixing holes 313 spaced apart from each other in the left-right direction are formed at the bottom of the backboard body 31. Each chassis securing hole 313 may be opposite a corresponding back plate securing hole 223 on the chassis flange 22 so that the back plate body 31 can be conveniently secured to the chassis flange 22 by suitable fasteners (e.g., bolts, nuts, etc.). Alternatively, the number of the chassis fixing holes 313 may be set to other suitable number more or less than 4.

Fig. 10 is a D-part enlarged view of an embodiment of a back plate of a base plate assembly for an air conditioner of the present invention shown in fig. 9. As shown in fig. 9 and 10, in one or more embodiments, the back plate body 31 is provided with clamping protrusions 311 symmetrically arranged on the left and right sides. Each catching protrusion 311 is configured to extend perpendicularly from the back plate body 31 toward the front of the chassis body 21. The catching projections 311 are positioned near the circumferential edge of the back plate body 31 so as to be fitted with the upper mounting plates 42 of the diagonal draw bars 40. The engaging protrusion 311 may be formed by a stamping process. The arrangement of the clamping protrusions 311 can enhance the structural strength and bending resistance of the connection between the backboard body 31 and the diagonal draw bar 40. In addition, the clamping protrusion 311 can be provided to form a clamping cavity 3111 located on the rear surface 314 of the back plate body 31 and used for receiving the upper mounting plate 42, so as to improve the assembly efficiency and the assembly precision of the upper mounting plate 42. That is, rear surface 314 of back plate body 31 forms a rear surface of clamping protrusion 311, and a rear surface of clamping protrusion 311 forms a bottom surface of clamping cavity 3111.
