When the RV is driving uphill or downhill, the air volume at the first air inlet decreases due to the tilt of the first air inlet relative to the horizontal plane. When the first air volume sensor detects that the air volume at the first air inlet is too small, it controls the first drive device to drive the first cover plate to widen the opening of the first air inlet. When the first air volume sensor detects that the air volume at the first air inlet is too large, it controls the first drive device to drive the first cover plate to narrow the opening of the first air inlet. This ensures that the air entering the condenser from the first air inlet is always maintained at a suitable air volume, thereby keeping the condenser in an optimal heat exchange state, enabling the RV air conditioner to exert its optimal cooling capacity and optimize energy efficiency.

Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] First, existing RV air conditioners are described. The size and direction of the air inlet for the outdoor unit's heat exchange is usually fixed. If the RV is traveling on uneven road conditions, such as climbing or descending slopes, the air inlet angle of the outdoor unit will tilt, affecting the airflow and consequently the heat exchange of the condenser inside. This results in incomplete heat exchange, underutilization of the condenser's performance, low energy efficiency, and a reduced user experience. Therefore, improving the user experience of RV air conditioners when traveling on uneven road conditions is a pressing technical problem that needs to be solved. The following implementation method is proposed to address this issue.

[0028] Example 1

[0029] like Figure 1 As shown, to address the problem that the air inlet of the outdoor unit 1 tilts and affects the air intake when the RV is climbing or descending a slope, resulting in poor heat exchange performance of the condenser, the RV air conditioner of this invention includes an outdoor unit 1. The outdoor unit 1 includes a first air inlet 11, which is located on a first side of the outdoor unit 1, facing the front of the RV. Figure 1(In the direction indicated by the middle arrow), a movable first cover plate (not shown in the figure) is provided at the first air inlet 11. The first cover plate is connected to a first driving device (not shown in the figure). The first cover plate is used to adjust the opening size of the first air inlet 11. The outdoor unit 1 also includes a first air volume sensor 16. The first air volume sensor 16 is used to obtain the air volume at the first air inlet 11. The first driving device and the first air volume sensor 16 are both communicatively connected to the controller 15 of the air conditioner so that the outdoor unit 1 can control the opening size of the first air inlet 11 based on the air volume at the first air inlet 11.

[0030] The outdoor unit 1 also includes a second air inlet 12, which is located on the second side of the outdoor unit 1, facing the side of the RV. A movable second cover (not shown in the figure) is provided at the second air inlet 12, and the second cover is connected to a second drive device (not shown in the figure). The second cover is used to adjust the opening size of the second air inlet 12. The outdoor unit 1 also includes a second airflow sensor 16, which is used to acquire the airflow at the second air inlet 12. Both the second drive device and the second airflow sensor 16 are communicatively connected to the air conditioner's controller 15, so that the outdoor unit 1 can control the opening size of the second air inlet 12 based on the airflow at the second air inlet 12. Additionally, the outdoor unit 1 also includes an air outlet 13, which is located on the top surface or a third side of the outdoor unit 1, facing the rear of the RV.

[0031] When the RV of the present invention is traveling on a hill or downhill road, the first air inlet 11 of the outdoor unit 1 of the RV air conditioner will tilt upward or downward, affecting the air intake of the outdoor unit 1. At this time, the first air volume sensor 16 obtains the air intake at the first air inlet 11. When the first air volume sensor 16 detects that the air intake at the first air inlet 11 is too small, it controls the first drive device to drive the first cover plate to widen the opening of the first air inlet 11. When the first air volume sensor 16 detects that the air intake at the first air inlet 11 is too large, it controls the first drive device to drive the first cover plate to narrow the opening of the first air inlet 11, so that the air entering the condenser from the first air inlet 11 is always kept at a suitable air intake. When the RV travels on a curve, the air intake volume of the two second air inlets 12 on the two second sides of the outdoor unit 1 will differ. The air intake volume of the second air inlet 12 located on the inside of the curve will increase, while the air intake volume of the second air inlet 12 located on the outside of the curve will decrease. At this time, the second air volume sensor 16 acquires the air intake volume at the two second air inlets 12. When it detects that the air intake volume at the second air inlet 12 is too small, it controls the second drive device to drive the second cover plate to widen the opening of the second air inlet 12. When it detects that the air intake volume at the second air inlet 12 is too large, it controls the second drive device to drive the second cover plate to narrow the opening of the second air inlet 12, so that the air entering the condenser from the first air inlet 11 is always kept at a suitable intake volume. In addition, those skilled in the art can set the air outlet 13 on the top surface of the outdoor unit 1 (e.g., Figure 1 Alternatively, the air outlet 13 can be located on the third side of the outdoor unit 1 facing the rear of the vehicle to reduce the air pressure of the air outlet 13. These changes are all within the protection scope of this invention.

[0032] In addition, the present invention also provides a motorhome, including the motorhome air conditioner described in any of the above embodiments.

[0033] Example 2

[0034] This invention also provides a control method for a motorhome air conditioner. The motorhome air conditioner includes an outdoor unit with a first air inlet disposed on a first side of the outdoor unit, facing the front of the motorhome. A movable first cover is provided at the first air inlet, and the first cover is connected to a first driving device. The first cover is used to adjust the opening size of the first air inlet. The outdoor unit also includes a first airflow sensor for acquiring the airflow at the first air inlet. Both the first driving device and the first airflow sensor are communicatively connected to the air conditioner's controller. Figure 2 As shown, the control methods include:

[0035] S1. Control the first air volume sensor to obtain the air volume at the first air inlet;

[0036] S2. Compare the air volume at the first air inlet with the first preset air volume;

[0037] S3. Based on the comparison result, control the first drive device to drive the first cover plate to extend or retract to adjust the opening size of the first air inlet.

[0038] In the above steps, step S3 further includes:

[0039] S31. If the air volume at the first air inlet is less than the first preset air volume, control the first drive device to drive the first cover plate to retract and increase the opening of the first air inlet.

[0040] S32. If the air volume at the first air inlet is greater than the first preset air volume, control the first driving device to drive the first cover plate to extend and reduce the opening of the first air inlet.

[0041] S33. If the air volume at the first air inlet is equal to the first preset air volume, then the opening size of the first air inlet will not be adjusted.

[0042] In the above-described implementation, the first air volume sensor is controlled to acquire the air volume at the first air inlet. The air volume at the first air inlet is compared with the first preset air volume. If the air volume at the first air inlet is less than the first preset air volume, the first drive device is controlled to drive the first cover plate to retract, thereby increasing the opening of the first air inlet and increasing the air volume. If the air volume at the first air inlet is greater than the first preset air volume, the first drive device is controlled to drive the first cover plate to extend, thereby decreasing the opening of the first air inlet and reducing the air volume. If the air volume at the first air inlet is equal to the first preset air volume, the opening size of the first air inlet is not adjusted. This ensures that the air entering the condenser from the first air inlet is always kept at a suitable intake volume, thereby keeping the condenser in an optimal heat exchange state, enabling the RV air conditioner to exert its optimal cooling capacity and optimize energy efficiency.

[0043] Example 3

[0044] Based on the aforementioned Embodiment 2, the outdoor unit further includes a second air inlet, which is located on the second side of the outdoor unit facing the side of the RV. A movable second cover is provided at the second air inlet, and the second cover is connected to a second driving device. The second cover is used to adjust the opening size of the second air inlet. The outdoor unit also includes a second airflow sensor, which is used to acquire the airflow at the second air inlet. Both the second driving device and the second airflow sensor are communicatively connected to the air conditioner's controller. The outdoor unit also includes a tilt sensor, which is used to acquire the tilt angle of the outdoor unit. The tilt sensor is communicatively connected to the air conditioner's controller. Figure 3 , Figure 4 As shown, the control method also includes:

[0045] S4. Control the tilt sensor to obtain the tilt angle of the outdoor unit;

[0046] S5. Control the second air volume sensor to obtain the air volume at the second air inlet;

[0047] S6. Compare the air volume at the second air inlet with the second preset air volume;

[0048] S7. Based on the comparison results and the tilt angle of the outdoor unit, control the first drive device and / or the second drive device to extend or retract the first cover plate and / or the second cover plate to adjust the opening size of the first air inlet and / or the second air inlet.

[0049] Of the above steps, step S7 further includes:

[0050] S71. If the outdoor unit is tilted towards the front of the RV and the air intake at the first air inlet is less than the first preset air intake, then control the first drive device to drive the first cover to retract and increase the opening of the first air inlet.

[0051] S72. If the outdoor unit is tilted towards the front of the RV and the air intake at the first air inlet is greater than the first preset air intake, then control the first drive device to drive the first cover plate to extend and reduce the opening of the first air inlet.

[0052] S73. If the outdoor unit is tilted towards the front of the RV and the air intake at the first air inlet is equal to the first preset air intake, then the opening size of the first air inlet will not be adjusted.

[0053] S74. If the outdoor unit is tilted towards the vehicle body and the air intake at the second air inlet is less than the second preset air intake, then control the second drive device to drive the second cover to retract and increase the opening of the second air inlet.

[0054] S75. If the outdoor unit is tilted towards the vehicle body and the air intake at the second air inlet is greater than the second preset air intake, then control the second drive device to drive the second cover plate to extend and reduce the opening of the second air inlet.

[0055] S76. If the outdoor unit is tilted towards the vehicle body and the air intake at the second air inlet is equal to the second preset air intake, then the opening size of the second air inlet will not be adjusted.

[0056] In the above implementation method, the tilt sensor is first controlled to obtain the tilt angle of the outdoor unit. If the outdoor unit tilts towards the front of the RV, the first drive device is controlled to drive the first cover plate to extend or retract to adjust the opening size of the first air inlet. The specific control method for driving the first cover plate to extend or retract is consistent with the logic of steps S31, S32 and S33 in the above embodiment two, and will not be repeated here. If the outdoor unit is tilted towards the RV or the RV enters a curve, the air intake volume of the two second air inlets on the two second sides of the outdoor unit will differ. The air intake volume of the second air inlet located on the inside of the curve will increase, while the air intake volume of the second air inlet located on the outside of the curve will decrease. At this time, the second air volume sensor will obtain the air intake volume at the two second air inlets and compare it with the second preset air intake volume. When the air intake volume at the second air inlet is less than the second preset air intake volume, the second drive device will be controlled to drive the second cover plate to increase the opening of the second air inlet. When the air intake volume at the second air inlet is greater than the second preset air intake volume, the second drive device will be controlled to drive the second cover plate to decrease the opening of the second air inlet. When the air intake volume at the second air inlet is equal to the second preset air intake volume, the opening size of the second air inlet will not be adjusted, so that the air entering the condenser from the second air inlet is always kept at a suitable intake volume.

[0057] Example 4

[0058] A photovoltaic panel is installed on the first cover of the outdoor unit. The photovoltaic panel is electrically connected to the RV's energy storage box 14. Figure 1 , Figure 5 As shown, the control method also includes:

[0059] S8. Obtain the remaining power information of the energy storage box 14;

[0060] S9. Compare the remaining power of the storage box 14 with the first preset power.

[0061] S10. Based on the comparison result, control the first driving device to drive the first cover plate to extend or retract.

[0062] Of the above steps, step S10 further includes:

[0063] S10a. If the remaining power of the storage box 14 is less than or equal to the first preset power, then control the first drive device to drive the first cover plate to extend.

[0064] S10b If the remaining power of the energy storage box 14 is greater than the first preset power, then control the first drive device to drive the first cover plate to retract.

[0065] In the above-described implementation, the remaining power information of the energy storage box 14 is first obtained. The remaining power of the energy storage box 14 is compared with a first preset power level. If the remaining power of the energy storage box 14 is less than or equal to the first preset power level, the first driving device is controlled to extend the first cover and charge the energy storage box 14. If the remaining power of the energy storage box 14 is greater than the first preset power level, the first driving device is controlled to retract the first cover to stop charging. Thus, by installing a photovoltaic panel on the first cover, automatic charging of the RV's energy storage box 14 is achieved, reducing the risk of power outages in the RV. Furthermore, those skilled in the art will understand that a photovoltaic panel can also be installed on a second cover and the above logic applied to charge the RV's energy storage box 14. These modifications do not exceed the technical principles of this invention and are therefore also included within the scope of protection of this invention.

[0066] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0067] Those skilled in the art will understand that the aforementioned RV air conditioner also includes other known structures, such as processors, controllers, and memories. These memories include, but are not limited to, random access memory (RAM), flash memory, read-only memory (ROM), programmable read-only memory (PROM), volatile memory, non-volatile memory, serial memory, parallel memory, or registers. Processors include, but are not limited to, CPLD / FPGA, DSP, ARM processors, and MIPS processors. To avoid unnecessarily obscuring the embodiments of this disclosure, these known structures are not shown in the accompanying drawings.

[0068] Although the steps in the above embodiments are described in the above order, those skilled in the art will understand that in order to achieve the effect of this embodiment, different steps do not need to be executed in such order. They can be executed simultaneously (in parallel) or in reverse order. For example, steps S4 and S5 can be executed simultaneously or in sequence. These simple variations are all within the protection scope of this invention.

[0069] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
