The mobile air conditioner can be a single-cooling type air conditioner or a cooling and heating type air conditioner. For convenience of description, a single cooling type air conditioner is exemplified in the following description.

In an embodiment of the present invention, as shown in fig. 1 to 4, the chassis assembly 100 includes a chassis body 110, a water receiving tank 120, a water level detecting tank 130, and a drainage tank 140, wherein the water receiving tank 120 is disposed on the chassis body 110; the water level detection groove 130 is disposed on the chassis body 110 to provide a water level switch, and the drainage groove 140 communicates the water receiving groove 120 and the water level detection groove 130.

Specifically, the chassis body 110 has a groove structure. The base plate body 110 is provided with a water receiving groove 120, a water level detection groove 130 and a drainage groove 140, and the water receiving groove 120 is arranged in the middle of the base plate body 110 and can be used for collecting condensed water generated by a heat exchanger of the mobile air conditioner. The water level detection tank 130 is disposed at one side of the water receiving tank 120, the water level detection tank 130 may be disposed adjacent to the water receiving tank 120, and of course, the water level detection tank 130 may also be disposed away from the water receiving tank 120, and the specific position of the water level detection tank 130 is not limited herein. The water level detection tank 130 is mainly used for installing a water level switch, and the shape of the water level detection tank 130 is not particularly limited, for example, the water level detection tank 130 may be square, circular, trapezoidal, or other irregular shapes.

In the embodiment of the present invention, the water level detection groove 130 is communicated with the water receiving groove 120 through the drainage groove 140, on one hand, the drainage groove 140 can drain the water in the water receiving groove 120 into the water level detection groove 130, so that the water level switch can conveniently detect the water level; on the other hand, the drainage groove 140 can prevent dirt such as sludge in the water receiving groove 120 from flowing into the water level detection groove 130, so that the dirt such as sludge is effectively prevented from adhering to the float of the water level switch, and the detection sensitivity of the water level switch is improved. The drainage groove 140 may be disposed inside the water receiving groove 120, outside the water receiving groove 120, or both inside and outside the water receiving groove 120. The drainage groove 140 may be formed to communicate the water receiving groove 120 with the water level detection groove 130, and is not particularly limited herein.

The chassis assembly 100 of the present invention comprises a chassis body 110, a water receiving tank 120, a water level detecting tank 130 and a drainage tank 140, wherein the water receiving tank 120 is arranged on the chassis body 110; the water level detection groove 130 is formed in the chassis body 110 and is installed with a water level switch, and the drainage groove 140 communicates the water receiving groove 120 and the water level detection groove 130; therefore, by arranging the independent water level detection groove 130 to install the water level switch and simultaneously improving the communication between the drainage groove 140 and the water receiving groove 120 and the water level detection groove 130, on one hand, the position of the water level detection groove 130 can be flexibly selected, the space utilization rate of the chassis body 110 is improved, on the other hand, the phenomenon that the water level switch fails due to dirt adhered to a floater of the water level switch can be avoided, and the detection sensitivity of the water level switch is effectively improved.

Referring to fig. 1 to 4, in an embodiment, a communication port 131 communicated with the drainage groove 140 is formed on a groove wall of the water level detection groove 130. In this embodiment, the communication port 131 is formed in the wall of the water level detection groove 130, so that the condensed water in the drainage groove 140 can be easily introduced into the water level detection groove 130.

In order to prevent the drainage groove 140 from being clogged by the sludge or the like, the width d of the communication port 131 may be set to be 8mm or more (as shown in fig. 4), considering that the condensed water may be contaminated with the sludge or the like. Because if the width d of the communication port 131 is less than 8mm, dirt such as sludge is likely to block the communication port 131 to prevent the condensed water in the drainage groove 140 from flowing into the water level detection groove 130.

And/or, as shown in fig. 4, in order to prevent the drainage groove 140 from being blocked by the sludge and other dirt, the height h of the communication port 131 may be greater than or equal to 8mm and less than or equal to 12 mm.

Specifically, the height h of the communication port 131 may be 8mm, 9mm, 10mm, 11mm, 12mm, or any value therebetween. If the height h of the communication port 131 is less than 8mm, the communication port 131 is too small, and dirt such as sludge is likely to block the communication port 131 to prevent the condensed water in the drainage groove 140 from flowing into the water level detection groove 130. If the height h of the communication port 131 is greater than 12mm, the communication port 131 is oversized, so that water may fly out of the communication port 131 when the paddling wheel 180 is used for fetching water, and a problem of water flying occurs, so that the water stored in the chassis body 110 may even fly out of the mobile air conditioner. Therefore, by setting the height h of the communication port 131 to be 8mm or more and 12mm or less, clogging of the communication port 131 by dirt such as sludge can be prevented and water can be prevented from flying out of the communication port 131 when the water pouring wheel 180 pours water.

Alternatively, the width of the drainage groove 140 may be the same as the width of the communication port 131. The width of the drainage groove 140 is greater than or equal to 8 mm. Also, if the width of the drainage groove 140 is less than 8mm, dirt such as sludge is easily deposited on the bottom of the drainage groove 140, resulting in poor drainage. Therefore, in order to ensure that the condensed water in the water receiving tank 120 can smoothly flow in the drainage groove 140 and flow into the water level detection groove 130, the width of the drainage groove 140 may be greater than or equal to 8 mm.

Referring to fig. 1 and 2, in an embodiment, the water level detection groove 130 is disposed adjacent to the water receiving groove 120, a bottom surface of the water level detection groove 130 is lower than a bottom surface of the water receiving groove 120, and the drainage groove 140 is a groove formed at a bottom of the water receiving groove 120.

In this embodiment, since the bottom surface of the water receiving tank 120 is higher than the bottom surface of the water level detection tank 130, the drainage groove 140 is formed at the bottom of the water receiving tank 120, and the water receiving tank 120 and the water level detection tank 130 are communicated through the drainage groove 140, so that the condensed water in the water receiving tank 120 can flow into the drainage groove 140 and then flow into the water level detection tank 130 through the drainage groove 140. Here, the bottom of the drainage groove 140 may be flush with the bottom of the water level detection groove 130, but the bottom of the drainage groove 140 may be slightly higher than the bottom of the water level detection groove 130, and is not particularly limited.

It should be noted that, if the bottom of the drainage groove 140 is flush with the bottom of the water level detection groove 130, when the condensed water in the water receiving groove 120 and the water level detection groove 130 needs to be drained, the drainage hole on the water receiving groove 120 may be opened, and at this time, the condensed water in the water level detection groove 130 may flow into the water receiving groove 120 through the drainage groove 140 and finally be drained through the drainage hole of the water receiving groove 120. If the bottom of the drainage groove 140 is slightly higher than the bottom of the water level detection groove 130, a drainage hole may be formed in the water level detection groove 130, so that when the condensed water in the water level detection groove 130 needs to be drained, the drainage hole in the water level detection groove 130 may be directly opened.

Considering that the drainage groove 140 is a groove formed at the bottom of the water receiving groove 120, the bottom of the drainage groove 140 is lower than the bottom of the water receiving groove 120, so that the condensed water in the water receiving groove 120 can flow into the drainage groove 140. The diversion inclined plane 141 may be a plane structure or a curved structure, and is not particularly limited. By arranging the diversion inclined plane 141, the condensed water in the water receiving groove 120 can smoothly flow into the diversion groove 140, the noise is reduced, and meanwhile, the water drops are prevented from splashing everywhere.

Further, a notch groove 142 is formed in a wall of the water receiving groove 120, and the notch groove 142 extends in the vertical direction and is communicated with the drainage groove 140. The notch groove 142 is formed in the wall of the water receiving groove 120, so that the mold stripping is facilitated, and the condensed water in the drainage groove 140 can be facilitated to better flow to the communication port 131 and flow into the water level detection groove 130 through the communication port 131.

Referring to fig. 1, 2, and 3, in an embodiment, the drainage groove 140 extends along a width direction of the water receiving groove 120, a water collecting groove 150 is disposed at a bottom of the water receiving groove 120, and the water collecting groove 150 extends along a length direction of the water receiving groove 120 to communicate with the drainage groove 140.

In this embodiment, by providing the water collecting groove 150 at the bottom of the water receiving groove 120, the condensed water in the water receiving groove 120 is collected in the water collecting groove 150, flows into the drainage groove 140 along the water collecting groove 150, and finally flows into the water level detection groove 130 through the drainage groove 140. Optionally, the water collection groove 150 is disposed in the middle of the water receiving groove 120, so that the condensed water on both sides of the water receiving groove 120 flows into the water collection groove 150 in the middle thereof.

In one embodiment, a filter screen is disposed at the communication port 131 to filter the condensed water flowing from the drainage groove 140 to the water level detection groove 130. The mesh number of the filter screen can be 22-25, so that the filter screen can filter large particles such as flocks and hairs in water, the filtered water flows to the water level detection groove 130, and the communication opening 131 can be prevented from being blocked by the flocks and the hairs.

Optionally, the filter screen is a stainless steel filter screen. Therefore, the filter screen can be effectively prevented from rusting or mildewing, the service life of the filter screen is prolonged, and the filtering performance of the filter screen is improved. The filter net is detachably provided at the communication port 131 to facilitate replacement of the filter net, and may be detachably provided on a side wall of the water level detection tank 130 using, for example, a bolt or the like.

Referring to fig. 3 to 6, in an embodiment, the chassis assembly 100 further includes a water level switch installed in the water level detection tank 130 for detecting a water level in the water level detection tank 130, so as to determine a water level condition in the water receiving tank 120.

The number of the water level switches may be one, two or more, and is not particularly limited. For the sake of detailed description, the two level switches include a first level switch 160 and a second level switch 170, wherein a first preset water level of the first level switch 160 is higher than a second preset water level of the second level switch 170. The first preset water level line of the first water level switch 160 is higher than the second preset water level line of the second water level switch 170, so that the water level of condensed water in the chassis is monitored secondarily, frequent alarming and frequent starting and stopping of the mobile air conditioner caused by the influence of factors such as a working environment on the single water level switch are avoided, the service life of the mobile air conditioner is prolonged, and the use stability of the mobile air conditioner is improved.

In particular, the first and second water level switches 160 and 170 may be floating water level switches. The first water level switch 160 is responsible for alarming and emergency braking, so that the mobile air conditioner is prevented from overflowing condensed water or being damaged by the condensed water in a severe environment; the second water level switch 170 is responsible for reducing the condensed water generating speed of the mobile air conditioner, so that the mobile air conditioner can automatically adjust the output power in a severe environment to ensure the normal operation of the mobile air conditioner.

When the water level line of the condensed water in the water level detection tank 130 reaches the second preset water level line of the second water level switch 170, the second water level switch 170 generates a second action signal, and the controller of the mobile air conditioner can control the mobile air conditioner to reduce the generation speed of the condensed water according to the second action signal; for example, the fan is controlled to reduce the wind speed to realize the reduction of the generation speed of the condensed water, and/or the water beating speed is accelerated by controlling the water beating motor to increase the consumption speed of the condensed water. When the water level line in the water level detection tank 130 reaches the first preset water level line of the first water level switch 160, the first water level switch 160 generates a first action signal, and the controller of the mobile air conditioner can control the mobile air conditioner to stop generating the condensed water according to the first action signal; for example, the compressor may be controlled to stop operating.

In an embodiment, a dirt storage tank is disposed at the bottom of the water level detection tank 130, and the dirt storage tank is located below the water level switch. The number of the dirt storage tanks is equal to that of the water level switches, and the dirt storage tanks and the water level switches are arranged in a one-to-one correspondence mode. By providing the dirt storage tank at the bottom of the water level detection tank 130, dirt such as sludge in the water level detection tank 130 can be deposited in the dirt storage tank, and thus the dirt such as sludge in the water level detection tank 130 can be prevented from adhering to the float of the water level switch. Specifically, the dirt storage groove is formed by a groove bottom recess of the water level detection groove 130.
