[0021] The present application is further described in detail below in conjunction with the accompanying drawings.

[0022] In view of the problem that mobile air conditioners in the prior art cannot provide a drainage-free function in a high humidity environment, the present application discloses a drainage-free structure of a mobile air conditioner and a mobile air conditioner, which improves the drainage-free efficiency, achieves the goal of eliminating the need for manual drainage in a high humidity environment, and increases the convenience of use.

[0023] like Figure 1 and Figure 2 As shown, the drainage-free structure of the mobile air conditioner includes a chassis 100 and a water pumping structure 200, wherein the chassis 100 includes a water pumping area 110 set at the lowest point and a plurality of flow channels 120 connected to the water pumping area 110, and the accumulated water at different positions of the chassis 100 is guided into the water pumping area 110 through the flow channels 120, wherein a plurality of baffles 111 are arranged around the water pumping area 110, and a water inlet notch 112 is formed on one side of the water pumping area 110, so that the accumulated water from different flow channels 120 can flow into the water pumping area 110 at different speeds; the water pumping structure 200 is fixed and arranged above the water pumping area 110, and the accumulated water in the water pumping area 110 is lifted upward to form water mist and evaporate, so as to realize the drainage-free function.

[0024] Furthermore, if Figure 6 and Figure 7 As shown, the water pumping area 110 is provided with an arc-shaped recess 113 corresponding to the water pumping structure 200, and the arc-shaped recess 113 forms the lowest point of the chassis 100; a first flow channel 121 connected to the arc-shaped recess 113 is formed in the water pumping area 110, and the first flow channel 121 is provided with a first slope to guide the condensed water falling from the top of the chassis 100 to flow into the arc-shaped recess 113. Furthermore, if Figure 2 and Figure 4 As shown, surrounding the water pumping area 110, the chassis 100 forms a second flow channel 122 outside the water pumping area 110, and the second flow channel 122 is provided with a second slope to guide the condensed water falling from above the chassis 100 to flow to the water inlet gap 112, and the second slope is smaller than the first slope.

The third flow channel 123 is provided with a third slope to guide the condensed water falling from the top of the chassis 100 to flow to the second flow channel 122, and then pass through the second flow channel 122 and enter the water pumping area 110 through the water inlet notch 112. The third slope is smaller than the second slope.

[0026] Furthermore, if Figure 2 and Figure 3 As shown, a guide plate 114 is provided at the water inlet notch 112 , and the guide plate 114 is disposed perpendicular to the baffle 111 and the bottom plate 100 to extend the distance of the condensed water from the second flow channel 122 into the water pumping area 110 .

[0027] Furthermore, if Figure 8 As shown, the water pumping structure 200 includes a motor 210 and a water pumping wheel 220. The motor 210 is fixed on the chassis 100; the water pumping wheel 220 is sleeved on the rotating shaft 211 of the motor 210 and is arranged above the water pumping area 110 corresponding to the arc-shaped recess 113. The water pumping wheel 220 rotates with the rotating shaft 211 to pump the accumulated water in the water pumping area 110 to both sides of the water pumping wheel 220.

[0028] Furthermore, if Fig. 9 As shown, the water wheel 220 includes a first wheel 221, a second wheel 222 and spokes 223. The first wheel 221 is arranged at the center of the water wheel 220 and sleeved on the rotating shaft 211 of the motor 210; the second wheel 222 is arranged around the outer side of the first wheel 221, and the second wheel 222 and the first wheel 221 are connected through a plurality of spokes 223, wherein the spokes 223 are extended and arranged corresponding to the involute of the first wheel 221, forming a water pumping structure of the water wheel 220, so as to lift the accumulated water in the water pumping area 110 to both sides of the water wheel 220.

[0029] Furthermore, if Fig.10 and Fig.11 As shown, the spoke 223 includes a water-splashing surface 2231 and a back-water surface 2232, the water-splashing surface 2231 includes a first water-splashing surface 22311 and a second water-splashing surface 22312 which are symmetrical with respect to the axial section of the water-splashing wheel 220, the back-water surface 2232 includes a first back-water surface 22321 and a second back-water surface 22322 which are symmetrical with respect to the axial section of the water-splashing wheel 220, and the angles between the first water-splashing surface 22311, the second water-splashing surface 22312, the first back-water surface 22321 and the second back-water surface 22322 and the axial section of the water-splashing wheel 220 are all greater than 90°, so as to lift the accumulated water in the water-splashing area 110 to both sides of the water-splashing wheel 220.

[0030] Furthermore, if Fig.12 and Fig.13As shown, the drainage-free structure further includes an evaporator 300 and a centrifugal fan 400. The evaporator 300 is fixed on the chassis 100 and is disposed above the water pumping structure 200, and the evaporator 330 sandwiches the water pumping wheel 220. The evaporator 330 heats the water mist raised by the water pumping structure 200 to increase the evaporation efficiency of the accumulated water; the centrifugal fan 400 is fixed on one side of the evaporator 300 to discharge the water vapor passing through the evaporator 300 out of the mobile air conditioner.

[0031] Furthermore, if Fig.12 and Fig.13 As shown, the drainage-free structure also includes a water level detector 500, which is fixed on the chassis 100 and is in communication connection with the evaporator 300. The water level detector 500 controls the power of the evaporator 300 according to the water level height in the chassis 100 to adjust the evaporation efficiency of the accumulated water.

[0032] Furthermore, if Figure 1 and Figure 2 As shown, the chassis 100 further includes an emergency drain port 130 , which is in communication with the flow channel 120 for emergency drainage. The water outlet of the emergency drain port 130 is flush with the side wall of the chassis 100 to avoid collision damage.

[0033] The present application sets a water pumping area at the lowest point of the chassis, and then sets a number of flow channels with different slopes to guide the accumulated water in the chassis to gather in the water pumping area, thereby ensuring that the water pumping structure can lift up all the accumulated water in the chassis and atomize it, and can still achieve the function of no drainage even in a high humidity environment. At the same time, in the present application, there are differences in the time when the accumulated water in different flow channels flows to the water pumping area, thereby preventing the accumulated water in the chassis from all gathering in the water pumping area at once, ensuring that the water pumping structure can maximize the water pumping effect, and even in a high humidity environment, the water pumping structure can still continue to pump water with high efficiency and achieve the function of no drainage.

[0034] In one embodiment of the present application, Fig.12 and Fig.13 As shown, the drainage-free structure of the mobile air conditioner includes a chassis 100, a water pumping structure 200, an evaporator 300, a centrifugal fan 400 and a water level detector 500, wherein the chassis 100 collects the accumulated water falling from above to the water pumping area 110, the water pumping structure 200 lifts the accumulated water in the water pumping area 110 to form water mist, and the evaporator 300 evaporates the water mist to form water vapor, and finally the centrifugal fan 400 draws the water vapor away and discharges it, thereby realizing the drainage-free function of the mobile air conditioner.

[0035] Specifically, Figure 2 and Figure 4As shown, the chassis 100 includes the water pumping area 110 and a plurality of flow channels 120 connected to the water pumping area 110. The water pumping area 110 is the lowest point of the chassis 100. Through the height difference of different positions on the chassis 100, the accumulated water falling into the chassis 100 is collected into the water pumping area 110 by the flow channels 120. However, if all the accumulated water in the chassis 100 is collected into the water pumping area 110 at one time, the water level in the water pumping area 110 may be too high, affecting the water pumping effect of the water pumping structure 200. Therefore, it is necessary to ensure that the water level in the water pumping area 110 is within a reasonable range, so as to ensure the water pumping efficiency of the water pumping structure 200.

[0036] Specifically, Figure 4 and Figure 5 As shown, a plurality of baffles 111 are arranged around the water-pumping area 110, and a water inlet notch 112 is formed on one side of the water-pumping area 110. The baffles 111 isolate the water-pumping area 110 from other positions of the chassis 100, so that the accumulated water in the chassis 100 can only enter the water-pumping area 110 through the water inlet notch 112, thereby preventing the accumulated water from being too quickly concentrated in the water-pumping area 110 and affecting the water-pumping efficiency of the water-pumping structure 200. Optionally, the water-pumping area 110 is arranged close to a side wall of the chassis 100, and the water inlet notch 112 corresponds to the side wall of the chassis 100, so that the paths between different positions of the chassis 100 and the water-pumping area 110 have different lengths, staggering the time for the accumulated water at different positions of the chassis 100 to flow to the water-pumping area 110, preventing too much accumulated water from being gathered in the water-pumping area 110, and allowing the water-pumping structure 200 to always maintain a high water-pumping efficiency.

[0037] Furthermore, if Figure 3 As shown, a diversion guide plate 114 is further provided at the water inlet gap 112, and the diversion guide plate 114 is arranged perpendicularly to the baffles 111 on both sides of the water inlet gap 112, and the diversion guide plate 114 is vertically fixed on the chassis 100, thereby forming an additional extension at the water inlet gap 112, so that the distance of the accumulated water entering the water pumping area 110 is further extended by the diversion guide plate 114, so that when the accumulated water converges to the water pumping area 110 at a steady speed, there will be a time difference when the accumulated water at a different relative position from the diversion guide plate 114 enters the water pumping area 110, so as to avoid all the accumulated water from being gathered in the water pumping area 110 at one time, thereby ensuring that the water pumping structure 200 always maintains a high water pumping efficiency.

[0038] Furthermore, if Figure 6 and Figure 7As shown, an arc-shaped depression 113 is provided in the water-pumping area 110, and the arc-shaped depression 113 forms the lowest point of the chassis 100, and the accumulated water in the chassis 100 eventually gathers in the arc-shaped depression 113. By arranging the water-pumping structure 200 above the arc-shaped depression 113, the accumulated water in the arc-shaped depression 113 is continuously lifted up, so that the accumulated water in the chassis 100 can be efficiently and stably discharged, and the drainage-free function in a high humidity environment can be achieved. Optionally, the water-pumping structure 200 matches the shape of the arc-shaped depression 113, and a gap is left between the water-pumping structure 200 and the arc-shaped depression 113 to ensure that the water-pumping structure 200 can lift up the accumulated water in the arc-shaped depression 113 to achieve the drainage-free function.

[0039] Further, in this embodiment, if Figure 1 and Figure 2As shown, the flow channel 120 includes a first flow channel 121, a second flow channel 122 and a third flow channel 123. The first flow channel 121 is arranged in the water-pumping area 110 and connected to the arc-shaped recess 113, so as to guide the accumulated water falling from the water-pumping area 110 to the arc-shaped recess 113. Further, the second flow channel 122 is arranged outside the water-pumping area 110 and surrounds the water-pumping area 110, so as to guide the accumulated water falling from the chassis 100 to the water inlet notch 112 and enter the water-pumping area 110. Optionally, the second flow channel 122 is arranged on a side of the water-pumping area 110 away from the water inlet notch 112, so as to guide all the accumulated water around the water-pumping area 110 to the water inlet notch 112, so as to avoid the accumulation of water around the water-pumping area 110. Further, the third flow channel 123 is arranged in other areas of the chassis 100, wherein the third flow channel 123 is connected with the second flow channel 122, and the accumulated water in other areas of the chassis 100 is guided to the second flow channel 122, and then guided by the second flow channel 122 to the water inlet notch 112 to enter the water pumping area 110. Optionally, part of the third flow channel 123 is directly connected with the water inlet notch 112, and the accumulated water in other areas of the chassis 100 is directly guided to the water inlet notch 112 to enter the water pumping area 110, so that the accumulated water in different areas enters the water pumping area 110 through different paths, so that the accumulated water in different areas of the chassis 100 enters the water pumping area 110 at different times, so as to avoid too much accumulated water in the water pumping area 110 to affect the water pumping efficiency of the water pumping structure 200, and ensure the working efficiency of the water pumping structure in a high humidity environment, so as to achieve the drainage-free function. Furthermore, the diversion guide plate 114 is arranged at the water inlet notch 112 to perform additional separation within the second flow channel 122 and the third flow channel 123, extending the distance of a specific position (perpendicular to the diversion guide plate 114) in the second flow channel 122 and the third flow channel 123 entering the water pumping area 110, thereby avoiding excessive water accumulation depth in the water pumping area 110 affecting the water pumping effect.

[0040] Furthermore, the first flow channel 121, the second flow channel 122 and the third flow channel 123 are all arranged as inclined surfaces, and are all inclined toward the water pumping area 110, so as to ensure that the water pumping area 110 is the lowest point of the chassis 100. The first flow channel 121 is provided with a first slope, the second flow channel 122 is provided with a second slope, and the third flow channel 123 is provided with a third slope, and the first slope> the second slope> the third slope, so that the accumulated water falling on the first flow channel 121 flows at the fastest speed, and the accumulated water falling on the third flow channel 123 flows at the slowest speed. At the same time, according to the different path settings of the first flow channel 121, the second flow channel 122 and the third flow channel 123 to the water pumping area 110, the accumulated water in the chassis 100 enters the water pumping area 110 in sequence, so as to avoid the rapid accumulation of too much accumulated water in the water pumping area 110, ensure the pumping efficiency of the water pumping structure 200, and realize the drainage-free function in a high humidity environment. Optionally, the first slope is 22°-26°, the second slope is 18°-22°, and the third slope is 16°-20°, and the first slope>second slope>third slope is ensured, so that the accumulated water in the chassis 100 enters the water pumping area 110 in sequence, avoiding the rapid accumulation of excessive water in the water pumping area 110, ensuring the water pumping efficiency of the water pumping structure 200, and realizing the drainage-free function in a high humidity environment.

[0041] Furthermore, if Fig.12 and Fig.13 As shown, the chassis 100 is also provided with an emergency drain port 130, which is arranged on the side wall of the chassis 100 and communicates with the flow channel 120, so as to allow the user to manually drain the water when the drainage-free structure fails and the water in the mobile air conditioner is too high. Specifically, the outlet of the emergency drain port 130 is flush with the side wall of the chassis 100, that is, the emergency drain port 130 will not protrude from the chassis 100, thereby avoiding collision with the emergency drain port 130 during movement or installation to cause damage, thereby improving the user experience.

[0042] Furthermore, if Fig.12As shown, the water pumping structure 200 is fixed on the chassis 100, and the water pumping structure 200 is arranged above the water pumping area 110. Specifically, the water pumping structure 200 includes a motor 210 and a water pumping wheel 220, wherein the motor 210 is fixed on the chassis 100, and the water pumping wheel 220 is sleeved on the rotating shaft 211 of the motor 210 and can rotate synchronously with the rotating shaft 211. After the water pumping wheel 220 is sleeved on the rotating shaft 211, the water pumping wheel 220 is arranged corresponding to the water pumping area 110, so that the accumulated water in the water pumping area 110 is pumped up when the water pumping wheel 220 rotates with the rotating shaft 211. Specifically, the water pumping wheel 220 is arranged above the arc-shaped depression 113 and matches the arrangement of the arc-shaped depression 113, so that the accumulated water in the arc-shaped depression 113, which is the lowest point of the chassis 100, is continuously pumped up and atomized, so as to realize the function of no drainage. Specifically, Figure 7 As shown, the water wheel 220 is matched with the arc structure of the arc recess 113, and a uniform gap is left between the water wheel 220 and the arc recess 113, so that the water wheel 220 can continuously raise the accumulated water in the arc recess 113 when rotating. Figure 3 and Figure 5 As shown, two guide plates 114 are provided at the water inlet notch 112, and the guide plates 114 are symmetrically arranged relative to the water wheel 220. Optionally, the spacing between the guide plates 114 is twice the width of the water wheel 220, so as to ensure that the condensed water will not affect the rotation of the water wheel 220 when entering the water pumping area 110 through the water inlet notch 112, and ensure that the water wheel 220 can continue to pump water. Optionally, the spacing between the guide plates 114 is 8-10 mm, and the width of the water wheel 220 is 4-5 mm.

[0043] Specifically, Figure 8 and Fig. 9 As shown, the water wheel 220 includes a first wheel 221, a second wheel 222, spokes 223 and a connecting portion 224. The first wheel 221 is arranged at the center of the water wheel 220 and is arranged in a round pancake shape as a whole, and is arranged coaxially with the rotating shaft 211, so that after the water wheel 220 is sleeved on the rotating shaft 211, the water wheel 220 can rotate synchronously and uniformly with the rotating shaft 211. Furthermore, the edge of the first wheel 221 is widened in the axial direction to match the setting of the spokes 223, so as to ensure the stable connection between the spokes 223 and the first wheel 221.

[0044] Furthermore, if Fig. 9As shown, one end of the spoke 223 is fixed on the outer side of the first wheel 221 and is extended along the involute direction of the first wheel 221. In other words, the contour of the first wheel 221 forms the involute of the spoke 223. Specifically, the first wheel 221 is a circular structure, and the spoke 223 intersects with all tangents of the first wheel 221 at right angles, so that the shape of the spoke 223 can minimize noise while maximizing the water pumping efficiency. Specifically, the extension direction of the spoke 223 corresponds to the direction in which the water wheel 220 rotates following the rotating shaft 211, so as to ensure the water pumping effect of the water wheel 220. Furthermore, a plurality of spokes 223 are evenly and evenly spaced on the outer side of the first wheel 221, and all of the spokes 223 are extended corresponding to an involute of the first wheel 221. Optionally, 20-30 spokes 223 are arranged on the outer side of the first wheel 221, which not only improves the overall water-pumping effect of the water-pumping wheel, but also avoids affecting the water-pumping effect of a single spoke due to too dense spokes.

[0045] Furthermore, if Fig.10 and Fig.11 As shown, the spoke 223 includes a water-spraying surface 2231 and a water-receiving surface 2232, wherein the axis of the spoke 223 corresponds to the involute extension of the first wheel 221, and the water-spraying surface 2231 and the water-receiving surface 2232 are arranged parallel to the axis of the spoke 223, and the water-spraying surface 2231 faces the rotation direction of the water-spraying wheel 220 following the rotation of the rotating shaft 211 to realize the water-spraying air power of lifting the accumulated water, while the water-receiving surface 2232 faces away from the rotation direction of the water-spraying wheel 220 following the rotation of the rotating shaft 211. Specifically, Fig.11 As shown, the water-pumping surface 2231 includes a first water-pumping surface 22311 and a second water-pumping surface 22312 symmetrical with respect to the axial section of the water-pumping wheel 220, and the angle between the first water-pumping surface 22311 and the second water-pumping surface 22312 and the axial section of the water-pumping wheel 220 is greater than 90°; the back water surface 2232 includes a first back water surface 22321 and a second back water surface 22322 symmetrical with respect to the axial section of the water-pumping wheel 220, and the angle between the first back water surface 22321 and the second back water surface 22322 and the axial section of the water-pumping wheel 220 is greater than 90°. By setting the angles of the water-pumping surface 2231 and the back water surface 2232 on the spokes 223, it is ensured that when the water-pumping wheel 220 rotates following the rotating shaft 211, the accumulated water below can be lifted to both sides of the water-pumping wheel 220, thereby cooperating with the evaporator to achieve the function of free drainage. Optionally, an angle between the first water-spraying surface 22311 , the second water-spraying surface 22312 , the first back water surface 22321 , the second back water surface 22322 and the axial cross section of the water-spraying wheel 220 is 92°-94°.

[0046] Furthermore, if Fig. 9 As shown, the second wheel 222 is a wheel-shaped structure, and the second wheel 222 is arranged around the outer side of the first wheel 221, the second wheel 222 is coaxial with the first wheel 221, and the second wheel 222 and the first wheel 221 are fixedly connected by the spokes 223. Specifically, the axial width of the second wheel 222 is equal to the axial width of the outer edge of the first wheel 221, the two ends of the spokes 223 are respectively fixed to the outer side of the first wheel 221 and the inner side of the second wheel 222, and the width of the spokes 223 remains uniform. When the water-pumping wheel 220 rotates synchronously with the rotating shaft 211, the first wheel 221, the second wheel 222 and the spokes 223 rotate synchronously, thereby avoiding vibration and noise during the water-pumping process and providing the required water-pumping effect.

[0047] Furthermore, if Fig.11 As shown, the inner side of the second wheel 222 is provided with a first surface 2221 and a second surface 2222 which are symmetrical with respect to the axial section of the water-pumping wheel, and the angle between the first surface 2221 and the second surface 2222 and the axial section of the water-pumping wheel 220 is greater than 90°, so that when the water-pumping wheel 220 rotates synchronously with the rotating shaft 211, the inner side surface of the second wheel 222 cooperates with the water-pumping surface 2231 and the water-repelling surface 2232 of the spoke 223 to lift the accumulated water to the two sides of the water-pumping wheel 220, and cooperates with the evaporators on both sides of the water-pumping wheel 220 to evaporate the lifted water mist, thereby ensuring the evaporation efficiency without increasing the lift of the accumulated water, and providing a low-noise and high-efficiency drainage-free function. Optionally, the angle between the first surface 2221 and the second surface 2222 and the axial cross-section of the water-spraying wheel 220 is 91°-93°, and is smaller than the angle between the first water-spraying surface 22311, the second water-spraying surface 22312, the first back water surface 22321 and the second back water surface 22322 and the axial cross-section of the water-spraying wheel 220.

[0048] Furthermore, if Figure 8As shown, the water wheel 220 is fixed on the rotating shaft 211 of the motor 210 through the connecting portion 224. Further, the connecting portion 224 is arranged on the central axis of the water wheel 220 and is arranged perpendicular to the water wheel 220. A through holding space 225 is formed in the connecting portion 224. The holding space 225 is adapted to the rotating shaft 211 to achieve the water wheel 220 being mounted on the rotating shaft 211. Further, the top end of the rotating shaft 211 is a semi-cylindrical setting, and the holding space 225 is a semi-cylindrical setting, so that the user can easily position the water wheel 220 and the motor 210 during the installation process to achieve quick installation. At the same time, when the motor 210 starts working, since the rotating shaft 211 is connected to the holding space 224 through a semi-cylindrical structure, the water-pumping wheel 220 and the rotating shaft 211 will not rotate relative to each other, ensuring that the water-pumping wheel 220 rotates synchronously with the rotating shaft 211 to achieve the water-pumping function.

[0049] Furthermore, in this embodiment, a corresponding thread is provided on the rotating shaft 211. After the water-pumping wheel 220 is mounted on the rotating shaft 211 through the clamping space 224, the water-pumping wheel 220 and the rotating shaft 211 are fixedly clamped by fixing screws in cooperation with the thread, thereby ensuring that after the motor 210 starts working, the water-pumping wheel 220 can continue to rotate synchronously with the rotating shaft 211 to achieve continuous water pumping work, ensuring that the accumulated water in the chassis 100 can be continuously lifted and atomized in a high humidity environment, thereby achieving a drainage-free function.

[0050] Furthermore, the evaporator 300 in the drainage-free structure of the mobile air conditioner described in the present application is fixed on the chassis 100 and is arranged above the water pumping area 110 and the water pumping structure 200. Specifically, Fig.12 and Fig.13 As shown, the evaporator 300 is disposed above the water wheel 220 to heat and evaporate the accumulated water raised by the water wheel 220 to form water vapor for easy discharge. Furthermore, the evaporator 300 is a compressor and a condenser, which provides a cooling or heating function for the mobile air conditioner. The accumulated water raised by the water wheel 220 is heated and evaporated by the waste heat generated by the evaporator 300 during operation, and the drainage-free function can be achieved without the need for additional energy, which is energy-saving and environmentally friendly. Furthermore, as Fig.14As shown, the evaporator 300 includes two rows of condensing tubes, and the water wheel 220 is sandwiched between the two rows of condensing tubes, so as to cooperate with the structural design of the water wheel 220 to ensure that the accumulated water lifted by the water wheel 220 can evaporate quickly to form water vapor. Specifically, through the structural design of the spokes 223 on the water wheel 220, it is ensured that the accumulated water is lifted to both sides of the water wheel 220 when the water wheel 220 rotates, so as to maximize the use of the evaporator 300 on both sides, and the evaporation efficiency of the lifted water mist can be guaranteed without increasing the head of the accumulated water, so as to achieve water lifting and evaporation with lower power, and provide a drainage-free function under silent conditions.

[0051] Furthermore, if Fig.12 and Fig.13 As shown, the centrifugal fan 400 in the drainage-free structure of the mobile air conditioner described in the present application is fixed to one side of the evaporator 300. Specifically, the centrifugal fan 400 is provided with an air inlet toward the evaporator 300, and an air outlet is provided at the top of the centrifugal fan 400. The centrifugal fan 400 forms a volute air duct, and the air passing through the evaporator 300 is drawn into and discharged from the mobile air conditioner, so that the accumulated water raised by the water wheel 220 is continuously discharged from the mobile air conditioner through the water vapor formed by the evaporator 300, thereby realizing the drainage-free function.

[0052] Furthermore, if Fig.12 and Fig.13 As shown, the water level detector 500 in the drainage-free structure of the mobile air conditioner of the present application is fixed on the chassis 100 and is arranged corresponding to the flow channel 120. Specifically, the water level detector 500 is in communication connection with the evaporator 300, and controls the power of the evaporator 300 according to the water level of the accumulated water in the chassis 100, so as to adjust the evaporation efficiency of the accumulated water. Specifically, the water level detector 500 is provided with a corresponding upper and lower limit of the water level. When the accumulated water in the chassis 100 is too high and exceeds the upper limit of the water level, it indicates that the current environmental humidity is high and the power of the evaporator 300 is not matched. At this time, the water level detector 500 controls the evaporator 300 to increase the temperature, so that the accumulated water raised by the water wheel 220 can evaporate faster to form water vapor, and then be discharged from the mobile air conditioner through the centrifugal fan 400; when the accumulated water in the chassis 100 is too low to below the lower limit of the water level, it indicates that the current environmental humidity is low and the power of the evaporator 300 is too high. At this time, the water level detector 500 controls the evaporator 300 to appropriately lower the temperature, so that the accumulated water raised by the water wheel 220 forms water vapor at a relatively slow speed, and then is discharged from the mobile air conditioner through the centrifugal fan 400. In this way, the drainage-free effect is guaranteed, and the overall power consumption can be adjusted according to the actual situation, so as to achieve the dual effects of energy saving and environmental protection and drainage-free.

[0053] In this embodiment, by specifically configuring the chassis 100 and the water pumping structure 200, it is ensured that the accumulated water in various places in the chassis 100 gathers to the water pumping area 110 at different speeds, thereby avoiding excessive accumulation of water in the water pumping area 110, so that the water pumping structure 200 can always maintain a high water pumping efficiency and achieve a uniform and lasting water pumping atomization effect. Even in a high humidity environment, the accumulated water in the chassis 100 can still be continuously lifted and atomized, thereby discharging the mobile air conditioner, achieving a drainage-free effect.

[0054] The present application also discloses a mobile air conditioner, comprising any of the above-mentioned drainage-free structures, so as to realize the drainage-free function of the mobile air conditioner.

[0055] In summary, the present application discloses a drainage-free structure of a mobile air conditioner and a mobile air conditioner, wherein the drainage-free structure includes a chassis and a water pumping structure, wherein the chassis includes a water pumping area set at the lowest point and a plurality of flow channels connected to the water pumping area, and the accumulated water at different positions of the chassis is guided to the water pumping area through the flow channels. Among them, a plurality of baffles are arranged around the water pumping area, and a water inlet gap is formed on one side of the water pumping area, so that the accumulated water from different flow channels flows into the water pumping area at different speeds. The water pumping structure is fixed and arranged above the water pumping area, and the accumulated water in the water pumping area is lifted upward to form water mist and evaporate, so as to realize the drainage-free function. By setting the water pumping area at the lowest point of the chassis, and setting a plurality of flow channels connected to the water pumping area to guide the accumulated water at other positions of the chassis to the water pumping area, it is ensured that the water pumping structure can lift and atomize all the accumulated water from different positions of the chassis, thereby realizing the drainage-free function in a high humidity environment.
