[0035] Please refer to Figures 1 to 5As shown, the utility model proposes a motorhome air conditioner 100, which includes a shell 1, a condensing device 2 and an evaporating device 4. The shell 1 forms a condensing chamber 11 and an evaporating chamber 12 that are spaced apart. The condensing device 2 includes a condensing fan 22, a compressor 23 and a condenser 21 arranged in the condensing chamber 11. The condenser 21 has a first concave surface 211 and a first convex surface 212. The first concave surface 211 and the cavity wall of the condensing chamber 11 are combined to form a first installation cavity 111. The condensing fan 22 is arranged in the first installation cavity 111. The first convex surface 212 and the cavity wall of the condensing chamber 11 are combined to form a second installation cavity 112. The compressor 23 is arranged in the second installation cavity 112 and is connected to the condenser 21; the evaporating device 4 is arranged in the evaporating chamber 12 and is connected to the compressor 23.

[0036] In this embodiment, if Figure 1 and Figure 2 As shown, the condensing device 2 and the evaporating device 4 in the RV air conditioner 100 are respectively arranged in the condensing chamber 11 and the evaporating chamber 12 of the shell 1. The setting of the shell 1 can protect the condensing device 2 and the evaporating device 4 from erosion by the external environment, ensure the safety of the condensing device 2 and the evaporating device 4 when in use, and extend the service life of the condensing device 2 and the evaporating device 4. The condensing chamber 11 and the evaporating chamber 12 are separated to reduce the heat transfer between the condensing chamber 11 and the evaporating chamber 12, so as to avoid the condensing device 2 and the evaporating device 4 from affecting each other during operation, thereby reducing the cooling or heating efficiency of the RV air conditioner 100. The condensing device 2 includes a condensing fan 22 and a condenser 21. The coolant flows in the condenser 21. The condensing fan 22 is used to cool the coolant in the condenser 21. A circulation pipe is arranged in the condenser 21, and the circulation pipes are overlapped to increase the circulation length of the coolant in the condenser 21, so that the condensing fan 22 can fully dissipate the heat of the coolant.

[0037] The condenser 21 has a first concave surface 211 and a first convex surface 212 in the cooling cavity to increase the surface area of ​​the condenser 21, directly increase the contact area between the condenser 21 and the air, indirectly increase the flow length of the coolant in the condenser 21, and further improve the cooling efficiency of the condensing fan 22 on the coolant in the condenser 21, thereby improving the cooling and heating efficiency of the RV air conditioner 100. At the same time, the condenser 21 has a first concave surface 211, and the first concave surface 211 and the cavity wall of the condensing cavity 11 are enclosed to form a first installation cavity 111, and the condensing fan 22 is arranged in the first installation cavity 111, so as to make full use of the concave space of the condenser 21, and at the same time, the condensing fan 22 is arranged close to the condenser 21, so as to fully cool the condenser 21.

[0038] The convex part of the condenser 21 is arranged close to the evaporating device 4, and the first convex part of the condenser 21 and the cavity wall of the condensing chamber 11 are enclosed to form a second installation cavity 112. The compressor 23 is arranged in the second installation cavity 112 and connected to the condenser 21, and is used to compress the coolant flowing from the evaporating device 4 to the condensing device 2. The compressor 23 is arranged in the second installation cavity 112 and is located between the condensing device 2 and the evaporating device 4. In this way, the pipeline arrangement from the condensing device 2 to the compressor 23 to the evaporating device 4 is smoother and more compact. Therefore, the condenser 21 has a first concave surface 211 and a first convex surface 212, which can make the arrangement of the condensing device 2 and the evaporating device 4 inside the shell 1 more reasonable and compact, and can also provide higher cooling capacity and heating capacity when the size of the RV air conditioner 100 is small.

[0039] In actual implementation, the first concave surface 211 and the first convex surface 212 of the condenser 21 are respectively arranged on both sides of the condenser 21. The first concave surface 211 of the condenser 21 is arranged facing the condensing fan 22. When the condensing fan 22 is arranged in the first installation cavity 111, the first concave surface 211 is surrounded by the condensing fan 22, so that the effective area of ​​the condensing fan 22 is larger and the cooling effect on the condenser 21 is better. The condensing fan 22 can be a double-inlet centrifugal fan, and the two air inlets of the fan are both arranged beyond the first concave surface 211. Due to the setting of the first concave surface 211, there is a certain distance between the air inlet of the condensing fan 22 and the first concave surface 211, thereby achieving a better cooling effect on the condenser 21 and improving the cooling and heating efficiency of the RV air conditioner 100.

[0040] In actual implementation, the RV air conditioner 100 also includes a throttling device, which is also arranged in the second installation cavity 112 together with the compressor 23, and is respectively connected to the condenser 21 and the evaporating device 4. The throttling device is arranged between the condenser 21 and the evaporating device 4, which facilitates the setting of connecting pipelines between the throttling device and the condenser 21 and the evaporating device 4, so that the internal structure of the RV air conditioner 100 is arranged more compactly.

[0041] In actual implementation, the shell 1 also has a partition, which divides the internal space of the shell 1 into a condensation chamber 11 and an evaporation chamber 12. An opening is provided on the partition for connecting the compressor 23 with the evaporation device 4. The opening should be filled with insulation material to reduce the mutual influence between the condensation device 2 and the evaporation device 4 during operation.

[0042] In one embodiment, if Figure 1 and Figure 2 As shown, the condensation chamber 11 is provided with a condensation fixing frame along the chamber wall, the condensation fixing frame is connected to the shell 1, the condensation fixing frame is provided with two limiting grooves, and the condenser 21 has a first end and a second end connected to each other, and the first end and the second end are respectively limited in the two limiting grooves.

[0043] In this embodiment, a condensation fixing frame is provided in the condensation chamber 11, and the condensation fixing frame supports and fixes the condenser 21 to prevent the condenser 21 from shaking due to the bumpy driving of the vehicle and affecting the normal operation of the condenser 21. The condensation fixing frame is arranged along the cavity wall of the condensation chamber 11 to avoid affecting the arrangement of other components in the condensation chamber 11, so as to facilitate the compact arrangement of the components in the condensation chamber 11. The condensation fixing frame is provided with a limiting groove, and the first end and the second end of the condenser 21 are respectively limited in the two limiting grooves to limit the condenser 21 in the condensation chamber 11.

[0044] In actual implementation, the first and second ends of the condenser 21 have pipelines extending therefrom. When the first and second ends extend into the limiting grooves, there are partial virtual spaces, which can be filled with buffers or foaming glue, and no specific limitation is made here.

[0045] In one embodiment, if Figure 1 and Figure 2 As shown, the shell 1 is provided with a condensation air inlet 13 and a condensation air outlet 14. The condensation air inlet 13 and the condensation air outlet 14 are both arranged on the side wall of the shell 1 and arranged close to the bottom wall of the shell 1. The condensation air inlet 13 is connected to the second installation cavity 112, and the condensation air outlet 14 is connected to the first installation cavity 111.

[0046] In this embodiment, the shell 1 has a condensation air inlet 13 and a condensation air outlet 14 connected to the condensation chamber 11, the condensation air inlet 13 provides air inlet for the condensation fan 22, and the condensation air outlet 14 provides air outlet for the condensation fan 22, so as to form an air flow in the condensation chamber 11 to cool the condenser 21; the condensation air inlet 13 and the condensation air outlet 14 are both arranged on the side wall of the shell 1 to prevent fallen leaves or other debris on the top of the RV air conditioner 100 from covering the condensation air inlet 13 and the condensation air outlet 14, affecting the condensation chamber 11 Normal operation of internal components; the condensation air inlet 13 and the condensation air outlet 14 are arranged close to the bottom wall of the shell 1 to discharge rainwater entering the condensation chamber 11; the condensation air inlet 13 is connected to the second installation chamber 112, and the condensation air outlet 14 is connected to the first installation chamber 111, so that the air path from the condensation air inlet 13 to the condensation fan 22 to the condensation air outlet 14 can pass through the first convex surface 212 and the first concave surface 211, so as to fully dissipate heat and cool the condenser 21 to improve the refrigeration efficiency of the RV air conditioner 100.

[0047] In actual implementation, the condensation air inlet 13 and the condensation air outlet 14 are respectively arranged facing the first convex surface 212 and the first concave surface 211 to increase the area of ​​the air path passing through the condenser 21. Multiple condensation air inlets 13 and condensation air outlets 14 can be arranged, and no specific limitation is made here.

[0048] In one embodiment, if Figure 1 , Figure 2 and Figure 4As shown, there are two condensation air inlets 13 , which are respectively located at the two ends of the second installation cavity 112 . The RV air conditioner 100 also includes an electronic control component 3 , which is arranged in the second installation cavity 112 . The electronic control component 3 and the compressor 23 are respectively arranged close to the two condensation air inlets 13 .

[0049] In this embodiment, the first convex surface 212 has an arc, so that the cross-sectional area of ​​the second installation cavity 112 gradually increases from the middle to the shell 1 at both ends, so that the second installation cavity 112 is divided into two parts, and the electronic control component 3 and the compressor 23 are respectively arranged in these two parts to make full use of the space of the second installation cavity 112 and make the components in the second installation cavity 112 more compact. At the same time, the two condensation air inlets 13 are respectively arranged on the shell 1 on both sides of the second installation cavity 112, so that the wind entering from the condensation air inlet 13 can cover the second convex surface 412, thereby ensuring the cooling efficiency of the condenser 21.

[0050] In actual implementation, the electronic control component 3 is electrically connected to the compressor 23, the condensing fan 22 and the evaporating device 4, and is used to control the operation and gear position of the compressor 23, the condensing fan 22 and the evaporating device 4. The RV air conditioner 100 also has a four-way valve, which is connected to the evaporating device 4 and the compressor 23. The four-way valve can be arranged in the second installation cavity 112, and is used to control the flow direction of the refrigerator in the condensing device 2, the compressor 23 and the evaporating device 4, so as to perform cooling or heating.

[0051] In one embodiment, if Figures 1 to 3 As shown, the electric control component 3 includes an electric control bracket 31, an electric control box 32 and a heat sink 33. The electric control bracket 31 is connected to the shell 1. The electric control box 32 is arranged on the electric control bracket 31 and is located between the condensation air inlet 13 and the top wall of the shell 1. The heat sink 33 is connected to one side of the electric control box 32 close to the condensation air inlet 13.

[0052] In this embodiment, the electric control component 3 is composed of an electric control bracket 31, an electric control box 32 and a heat sink 33. The electric control bracket 31 is detachably connected to the shell 1, and the electric control box 32 is arranged on the electric control bracket 31, so that the electric control box 32 is located between the condensation air inlet 13 and the top wall of the shell 1, that is, the electric control box 32 is located above the condensation bracket. In this way, when the RV is washed, the lateral car washing water cannot be poured from the condensation air inlet 13 to the electric control box 32, thereby improving the waterproof reliability of the electric control box 32 and avoiding water damage to the electric control box 32, which affects the normal operation of the RV air conditioner 100; the heat sink 33 is arranged close to the condensation air inlet 13 to achieve better heat dissipation effect.

[0053] In actual implementation, the electric control bracket 31 is connected to the shell 1 by screws or a snap-on structure. The electric control bracket 31 and the bottom wall of the shell 1 enclose a hollow space to avoid blocking the condensation air inlet 13 and reduce the resistance of the condensation air inlet 13 to the air entering.

[0054] In one embodiment, if Figure 1 and Figure 4 As shown, the condensing fan 22 has an air outlet channel 221 and a fan outlet connected to the air outlet channel 221, the fan outlet is connected to the condensing air outlet 14, and the cross-sectional area of ​​the air outlet channel 221 gradually increases from the end far from the fan outlet to the end close to the fan outlet.

[0055] In this embodiment, the fan outlet of the condensing fan 22 is connected to the condensing outlet 14, that is, the fan outlet is arranged toward the side wall of the housing 1, so that the outlet channel 221 of the condensing fan 22 is almost directly connected to the outside, thereby improving the air outlet efficiency of the condensing fan 22. At the same time, the fan outlet is arranged close to the bottom wall of the housing 1, so that when rainwater enters from the condensing outlet 14, the rainwater will be naturally discharged from the fan outlet and will not accumulate in the condensing fan 22, thereby avoiding the rainwater from causing corrosion or short circuit to the condensing fan 22 and affecting the normal operation of the condensing fan 22. The outlet cross-sectional area of ​​the outlet channel 221 gradually increases toward the fan outlet, thereby increasing the area of ​​the fan outlet. At the same time, the gradual increase in the cross-sectional area of ​​the outlet channel 221 can also reduce the flow resistance of air in the outlet channel 221, further increasing the air outlet efficiency of the condensing fan 22.

[0056] In actual implementation, the condensing fan 22 can be fixed in the first installation cavity 111 by means of a limiting structure and screws. The bottom wall of the air outlet channel 221 is arranged close to the bottom wall of the shell 1, and the top wall of the air outlet channel 221 is tilted toward the top wall of the shell 1, so that the cross-sectional area of ​​the air outlet channel 221 gradually increases toward the fan outlet. The tilting angle is between 0° and 30°, which is not specifically limited here. If the tilting angle of the air outlet channel 221 is too large, a larger setting space is required, which is not conducive to the small size requirement of the RV air conditioner 100.

[0057] In one embodiment, if Figure 1 and Figure 2 As shown, the evaporation device 4 includes an evaporation fan 42 and an evaporator 41. The evaporator 41 has a second concave surface 411 and a second convex surface 412. The second concave surface 411 and the cavity wall of the evaporation chamber 12 are enclosed to form a third installation cavity 121. The evaporation fan 42 is arranged in the third installation cavity 121. The second convex surface 412 and the cavity wall of the condensation chamber 11 are enclosed to form a fourth installation cavity 122 for accommodating pipelines.

[0058] In this embodiment, the evaporation device 4 is composed of an evaporation fan 42 and an evaporator 41. The evaporator 41 is used to circulate the cooled refrigerant. The provision of the second concave surface 411 and the second convex surface 412 increases the contact area between the evaporator 41 and the air, and improves the cooling efficiency of the evaporator 41 on the air, thereby improving the refrigeration efficiency of the RV air conditioner 100. The evaporation fan 42 delivers the air cooled by the evaporator 41 into the vehicle to achieve a refrigeration effect. The second concave surface 411 and the cavity wall of the evaporation chamber 12 are enclosed to form a third installation cavity 121. The evaporation fan 42 is arranged in the third installation cavity 121, so as to make full use of the space in the evaporation cavity 12, so that the evaporator 41 and the evaporation fan 42 are compactly installed, which is conducive to the small size requirement of the RV air conditioner 100. At the same time, the evaporation fan 42 is arranged in the concave part of the evaporator 41, so that the evaporator 41 surrounds the evaporation fan 42, and there is a certain distance between the evaporator 41 and the second concave surface 411, thereby improving the efficiency of the evaporation fan 42 in transmitting cold air. The second convex surface 412 and the wall of the condensing chamber 11 are combined to form a fourth installation chamber 122 . The fourth installation chamber 122 can be used to install wires, pipes or other components.

[0059] In actual implementation, the evaporating fan 42 is a double-inlet centrifugal fan, so as to increase the air intake efficiency of the evaporating fan 42. Due to the setting of the second concave surface 411, the two air inlets of the evaporating fan 42 are both set toward the evaporator 41, thereby improving the efficiency of the evaporating fan 42 in transmitting cold air.

[0060] In one embodiment, if Figure 1 , Figure 2 and Figure 5 As shown, the shell 1 is provided with an evaporation air inlet 16 and an evaporation air outlet 15, and the evaporation air inlet 16 and the evaporation air outlet 15 are both arranged on the bottom wall of the shell 1, the evaporation air outlet 15 is connected to the third installation cavity 121, and the evaporation air inlet 16 is connected to the fourth installation cavity 122, and is arranged along the edge of the evaporator 41.

[0061] In this embodiment, the evaporative air inlet 16 and the evaporative air outlet 15 are both arranged on the bottom wall of the shell 1. When the RV air conditioner 100 is installed on the roof of the RV, the evaporative air inlet 16 and the evaporative air outlet 15 are connected with the interior space of the vehicle. The evaporative air inlet 16 is used to allow the air in the vehicle to enter the evaporative chamber 12, and the evaporative air outlet 15 is used to allow the cooled air to enter the vehicle to achieve refrigeration; the evaporative air inlet 16 is connected to the fourth installation cavity 122, and the evaporative air outlet 15 is connected to the third installation cavity 121, so that the air in the vehicle entering from the evaporative air inlet 16 can fully contact with the evaporator 41 and be cooled, and then enter the vehicle from the evaporative air outlet 15.

[0062] In actual implementation, the evaporation air inlet 16 can be set along the edge of the evaporator 41, that is, the second convex surface 412, so as to maximize the area of ​​the evaporation air inlet 16 and improve the air intake efficiency of the evaporation air inlet 16; the air outlet of the evaporation fan 42 is directly connected to the evaporation air outlet 15 to ensure the efficiency of the evaporation fan 42 in blowing out cold air.

[0063] In one embodiment, if Figure 1 As shown, the condenser 21 and the evaporator 41 are connected to the shell 1 by EPP or screws; and / or, the condenser 21 and the evaporator 41 are arranged in a V shape to expand the contact area with the air; and / or, the setting angles of the condenser 21 and the evaporator 41 are both between 80 degrees and 100 degrees; and / or, the size of the evaporation air inlet 16 is 360mm*360mm.

[0064] In this embodiment, the condenser 21 and the evaporator 41 are arranged in a V shape to expand the contact area with the air and improve the cooling or heating effect of the air conditioner. At the same time, the condensing chamber 11 is divided into a first installation chamber 111 and a second installation chamber 112, and the evaporating chamber 12 is divided into a third installation chamber 121 and a fourth installation chamber 122. The setting angle of the condenser 21 and the evaporator 41 can be between 80° and 100°. Preferably, the setting angle of the condenser 21 and the evaporator 41 are both 90°.

[0065] In actual implementation, the condenser 21 and the evaporator 41 are detachably and obliquely connected to the shell 1 through EPP or screws.
