[0002] During the refrigeration and heating operations of a roof-mounted RV air conditioner, a large amount of condensate is generated on both the evaporator assembly and condenser assembly sides of the outdoor unit. Since the outdoor unit is installed on the roof of the RV, the common drainage method in the industry is to open a large number of overflow holes of different sizes and irregular shapes on the chassis of the outdoor unit for real-time drainage.

[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0035] As Figures 1 to 8 shown, the present invention provides a chassis assembly, including: a chassis 100, an inner air duct base 200 and an outer air duct base 300 that are arranged at intervals along a predetermined direction on the chassis 100. The inner air duct base 200 is used to install an evaporator assembly 400. The position of the chassis 100 between the inner air duct base 200 and the outer air duct base 300 is used to install a compressor 500. The outer air duct base 300 is used to install a condenser assembly 600; water storage tanks are arranged on the inner air duct base 200 and the outer air duct base 300, and drain holes for draining water to the chassis 100 are arranged in the water storage tanks; the upper surface of the chassis 100 includes a plurality of diversion grooves connected in sequence, and a water outlet communicating with the lower side of the chassis 100 is arranged on the bottom surface of one of the plurality of diversion grooves.

[0036] In this way, the present invention solves the problem in the prior art that the overall strength of the chassis of the outdoor unit of the overhead RV air conditioner is reduced due to excessive drainage holes opened on the chassis by the method of centralized drainage at the water outlet, and the water outlet can be connected to an external water storage component to collect condensed water for secondary utilization, which can effectively utilize water resources, solves the problem of waste of water resources caused by direct external discharge of a large amount of condensed water, and solves the problem that the discharged water will directly pour on the top of the RV and flow down along the RV body, thus soiling the appearance of the RV and forming obvious dirt marks after a long time.

[0037] As Figures 1 to 6 shown, the plurality of diversion grooves include a first diversion groove 110, a second diversion groove 120, and a third diversion groove 130 sequentially arranged in a predetermined direction. The first diversion groove 110 is located below the evaporator assembly 400, and the second diversion groove 120 is located below the compressor 500 and the condenser assembly 600; the minimum height of the bottom surface of the first diversion groove 110 is greater than the maximum height of the bottom surface of the second diversion groove 120, and the first diversion groove 110 and the second diversion groove 120 are connected by a first transition groove 112; the minimum height of the bottom surface of the second diversion groove 120 is greater than the maximum height of the bottom surface of the third diversion groove 130, and the second diversion groove 120 and the third diversion groove 130 are connected by a second transition groove 123; wherein, a first water outlet is provided at the third diversion groove 130.

[0038] Specifically, the bottom surface of the first transition groove 112 is a first inclined surface arranged at a predetermined angle with the horizontal direction, and the bottom surface of the second transition groove 123 is a second inclined surface arranged at a predetermined angle with the horizontal direction.

[0039] In this way, the height difference inside the chassis 100 can be used to smoothly discharge the condensed water in the first diversion groove 110 into the second diversion groove 120 below the compressor to realize the intermediate water storage function of the second diversion groove 120, and the condensed water in the second diversion groove 120 can be smoothly discharged into the third diversion groove 130 to be uniformly discharged at the first water outlet of the third diversion groove 130.

[0040] Specifically, the second diversion groove 120 includes a first groove section 121 and a second groove section 122. The first groove section 121 and the second groove section 122 are sequentially connected in a predetermined direction, and the width of the first groove section 121 in the direction perpendicular to the predetermined direction is greater than the width of the second groove section 122 in the direction perpendicular to the predetermined direction; and / or the chassis assembly includes a plurality of seals located on the lower side of the chassis 100; and / or a water level detection component and a drain valve are provided at the first water outlet to detect the water level in the third diversion groove 130 through the water level detection component and control whether the first water outlet discharges water and control the water discharge amount of the first water outlet.

[0041] AsFigure 2 and Figure 6 As shown in Figure 6 , the second diversion channel 120 includes a first channel segment 121 and a second channel segment 122. The first channel segment 121 and the second channel segment 122 are sequentially connected along a predetermined direction, and the width of the first channel segment 121 in the direction perpendicular to the predetermined direction is greater than the width of the second channel segment 122 in the direction perpendicular to the predetermined direction, so as to form a "T"-shaped second diversion channel 120.

[0042] Among them, considering that there is a risk of corrosion to the housing of the compressor 500 after being soaked in water for a long time, therefore, the highest position of the bottom surface of the second diversion channel 120 is lower than the lowest position of the housing of the compressor 500, so as to prevent accumulated water from contacting the housing of the compressor 500.

[0043] As Figure 2 shown, the chassis assembly includes a plurality of seals located on the lower side of the chassis 100. The plurality of seals include a first seal 700 and a second seal 800 sequentially arranged along a predetermined direction. The present invention utilizes the gap in the height direction between the lower surface of the chassis 100 formed by the seals installed on the lower side of the chassis 100 when installing the outdoor unit of the air conditioner of the RV and the top of the RV. While making the thickness of the chassis 100 uniform, the chassis 100 is set as a stepped diversion channel, ensuring the stability and reliability of the installation of the outdoor unit.

[0044] A water level detection component and a drain valve are provided at the first water outlet of the present invention, so as to detect the water level in the third diversion channel 130 through the water level detection component, and control whether the first water outlet discharges water and the water discharge volume of the first water outlet through the drain valve. The drain valve can be externally connected to a water storage component. When the water level in the third diversion channel 130 reaches a certain height (i.e., the height difference D3 between the bottom surface of the second diversion channel 120 and the bottom surface of the third diversion channel 130) or the water storage volume reaches a certain volume, the user can be prompted to perform multi-purpose and multi-form drainage by the indicator light flashing on the control panel of the indoor unit, so as to realize the centralized drainage function of the outdoor unit and effectively utilize water resources.

[0045] Specifically, the water level detection component is a water level switch.

[0046] As Figures 1 to 3 and Figure 7As shown in the figure, on the inner base 200 of the air duct, there is a first water storage tank 210 at least partially located below the evaporator assembly 400. A first drain hole 220 for draining water to the chassis 100 is provided in the first water storage tank 210. Among them, the first water storage tank 210 includes a third tank section 211 and a fourth tank section 212 that are perpendicular to each other and communicate with each other. The first drain holes 220 are provided on the bottom surfaces of the ends of the third tank section 211 away from the fourth tank section 212 and the bottom surfaces of the ends of the fourth tank section 212 away from the third tank section 211. The first water storage tank 210 discharges the condensed water generated by the evaporator assembly 400 into the first diversion groove 110 of the chassis 100 through a plurality of first drain holes 220.

[0047] As Figure 3 shown in the figure, the inner base 200 of the air duct includes a first horizontal plate body for enclosing the first water storage tank 210 and two first vertical plate bodies respectively located on opposite sides of the first horizontal plate body. A second horizontal plate body is connected to the side of each first vertical plate body away from the other first vertical plate body. The height difference D4 between the lower surface of the second horizontal plate body and the bottom surface of the first diversion groove 110 ranges from 10 mm to 20 mm.

[0048] Specifically, considering the possible water accumulation inside the inner base 200 of the air duct, it is necessary to make D4≥10 mm. At the same time, considering the limitations of other structures inside the inner base 200 of the air duct, it is necessary to make D4≤20 mm.

[0049] Preferably, the height difference D4 between the lower surface of the second horizontal plate body and the bottom surface of the first diversion groove 110 is 16 mm.

[0050] Specifically, the inner base 200 of the air duct includes a convex portion, and a drain groove 230 is provided on the convex portion. The chassis 100 includes a second water outlet 140 that communicates with the drain groove 230 and is located below the drain groove 230. Among them, the convex portion is located on the side of the first water storage tank 210 away from the outer base 300 of the air duct, and the second water outlet 140 is located on the side of the first diversion groove 110 away from the second diversion groove 120; and / or the height difference D1 between the upper surface of the convex portion and the bottom surface of the first diversion groove 110 ranges from 30 mm to 40 mm.

[0051] Among them, considering that the evaporator of the air conditioner of the RV is located directly above the indoor unit, and there are through holes for installing the air inlet and outlet channels on the roof of the RV, the condensed water generated by the evaporator assembly 400 will accumulate on the chassis 100 of the outdoor unit. However, excessive condensed water accumulation may leak into the interior of the RV through the through holes or air inlet and outlet channels on the roof. Therefore, a raised portion including a drain groove 230 is provided on the inner base 200 of the air duct, and a second water outlet 140 communicating with the drain groove 230 and located below the drain groove 230 is provided on the chassis 100, so as to discharge the condensed water in the chassis 100 to the outside of the outdoor unit through the drain groove 230 and the second water outlet 140 when there is more condensed water in the chassis 100, thereby forming a secondary anti-overflow structure.

[0052] Combined with the possible water accumulation situation inside the chassis 100, it is necessary to make D1≥30mm. At the same time, considering the limitations of other structures inside the chassis 100, it is necessary to make D1≤40mm.

[0053] Preferably, the height difference D1 between the upper surface of the raised portion and the bottom surface of the first diversion groove 110 is 35mm.

[0054] As Figure 7 shown, the first drain hole 220 is rectangular.

[0055] As Figure 1 、 Figure 2 、 Figure 5 and Figure 8 shown, a second water storage tank 310 is provided on the outer base 300 of the air duct, at least part of which is located below the condenser assembly 600. A second drain hole 320 for draining water to the chassis 100 is provided in the second water storage tank 310; among them, the second water storage tank 310 is a rectangular tank, and the second drain hole 320 is provided on the wall surface of the tank on the side of the second water storage tank 310 far from the inner base 200 of the air duct.

[0056] As Figure 5 shown, a water baffle 330 is provided on the outer base 300 of the air duct, and the water baffle 330 is located on the side of the outer base 300 of the air duct close to the chassis 100; the water baffle 330 is located on the side of the second drain hole 320 far from the tank body of the second water storage tank 310 and is spaced from the second drain hole 320 to form a first drainage channel 340; the side of the water baffle 330 close to the chassis 100 is spaced from the chassis 100 to form a second drainage channel 350. In this way, the condensed water generated by the condenser assembly 600 can be discharged into the third diversion groove 130 along the second drain hole 320, the first drainage channel 340 and the second drainage channel 350 for centralized water storage and drainage.

[0057] Among them, one side of the water baffle 330 close to the second drain hole 320 is the stop side 331. The stop side 331 is perpendicular to the bottom surface of the second water storage tank 310 and is spaced from the second drain hole 320 to form the first drainage channel 340. The bottom surface of the second transition groove 123 is a second inclined surface arranged at a predetermined angle with the horizontal direction, and the surface of the water baffle 330 close to the chassis 100 is a diversion inclined surface 332 corresponding to the second inclined surface. Among them, the second inclined surface and the diversion inclined surface 332 are parallel and spaced from each other to form the second drainage channel 350. In this way, the setting of the water baffle 330 with a wedge-shaped lower end avoids the phenomenon of condensate backflow in the third diversion groove 130 due to different road conditions of the RV, so that the condensate can smoothly flow into the third diversion groove 130. Among them, the lower end of the water baffle 330 should be as close as possible to the second inclined surface.

[0058] As Figure 4 and Figure 5 shown, considering the sheet metal mold and stamping process for processing the chassis 100, as well as the structural strength, installation levelness, and drainage effect of the chassis 100 comprehensively, the value range of the height difference D2 between the bottom surface of the first diversion groove 110 and the bottom surface of the second diversion groove 120 is 10 mm to 13 mm; and / or the value range of the height difference D3 between the bottom surface of the second diversion groove 120 and the bottom surface of the third diversion groove 130 is 10 mm to 14 mm.

[0059] Preferably, the height difference D2 between the bottom surface of the first diversion groove 110 and the bottom surface of the second diversion groove 120 is 11 mm; the height difference D3 between the bottom surface of the second diversion groove 120 and the bottom surface of the third diversion groove 130 is 12 mm.

[0060] Specifically, aiming at the problem that the overall strength of the chassis of the outdoor unit of the existing rooftop RV air conditioner is reduced due to too many drain holes opened on the chassis, in order to better prove the structural strength of the chassis of the chassis assembly of the present invention, a finite element simulation qualitative comparative analysis was carried out. Finally, it was obtained that the overall strength of the chassis of the chassis assembly of the present invention is increased by 10 - 15% compared with the overall strength of the chassis in the prior art.

[0061] The present invention provides an outdoor unit, including the above-mentioned chassis assembly. The outdoor unit further includes: an evaporator assembly 400, arranged on the inner base 200 of the air duct of the chassis assembly; a condenser assembly 600, arranged on the outer base 300 of the air duct of the chassis assembly; and a compressor 500, arranged on the chassis 100 and located between the evaporator assembly 400 and the condenser assembly 600.

[0062] The present invention provides an air conditioner, including the above-mentioned outdoor unit.

[0063] The present invention provides a vehicle, including the above-mentioned air conditioner.

[0064] Specifically, the above-mentioned vehicle is a recreational vehicle. The outdoor unit of the air conditioner is installed on the outer side of the roof of the recreational vehicle. The outdoor unit includes a housing (including an outer cover and a chassis assembly), and an evaporator assembly 400, a compressor 500, and a condenser assembly 600 located inside the housing. When the air conditioner is operating, both the evaporator assembly 400 and the condenser assembly 600 will generate condensed water.

[0065] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0066] The chassis assembly of the present invention includes: a chassis 100, an inner duct base 200 and an outer duct base 300 which are arranged at intervals along a predetermined direction on the chassis 100. The inner duct base 200 is used for installing the evaporator assembly 400, the position of the chassis 100 between the inner duct base 200 and the outer duct base 300 is used for installing the compressor 500, and the outer duct base 300 is used for installing the condenser assembly 600; water storage tanks are arranged on the inner duct base 200 and the outer duct base 300, and drain holes for draining water to the chassis 100 are arranged in the water storage tanks; the upper surface of the chassis 100 includes a plurality of flow guide grooves connected in sequence, and a water outlet communicating with the lower side of the chassis 100 is arranged on the groove bottom surface of one of the plurality of flow guide grooves. In this way, the present invention solves the problem that the overall strength of the chassis of the outdoor unit of the roof-mounted recreational vehicle air conditioner in the prior art is reduced due to too many drain holes opened on the chassis by the way of centralized drainage at the water outlet, and the water outlet can be connected to an external water storage component to collect condensed water for secondary utilization, which can effectively utilize water resources, solves the problem of waste of water resources caused by direct external discharge of a large amount of condensed water, and solves the problem that the discharged water will directly pour on the top of the recreational vehicle and flow down along the body of the recreational vehicle, thus soiling the appearance of the recreational vehicle and forming obvious dirt marks after a long time.
