The water tank area is communicated with the water absorption area and the water pumping area, the water tank area is used for buffering water on the chassis, the water in the water pumping area can be pumped to the condenser fin for evaporation through the water pumping wheel, and the water in the water absorption area is pumped out through the pump. In the in-service use process, water in the water tank area should flow into the water-beating area preferentially, normal work of the water-beating wheel is guaranteed at first, and in the prior art, the water in the water tank is easy to flow into the water-beating area directly, so that insufficient water flow in the water-beating area is caused, water on the chassis cannot be reasonably distributed, unnecessary action waste is caused, functions of the water-beating area cannot be effectively exerted, and meanwhile, when the water quantity on the chassis is too much, reasonable planning is needed to be carried out on the water flow, and shutdown is avoided.

Disclosure of Invention

In view of the above, the present invention aims to provide a chassis structure to reasonably plan the flow direction of water on the chassis and to improve the use efficiency of condensed water.

In order to achieve the above purpose, the technical scheme of the invention is realized as follows:

a chassis structure comprising: the area of absorbing water, basin district, area of beating water, water level control area still include:

the water retaining ribs are used for isolating the water absorbing area from the water tank area;

the converging part is positioned between the water pumping area and the water tank area and is close to a converging port of the water pumping area; a supporting rib is arranged in the water tank area;

the bottom of the water level control area is provided with a water storage tank, and at least one liquid level switch is arranged above the water storage tank;

the water in the water tank area flows to the water pumping area preferentially, then flows to the water absorbing area, and finally flows to the water level control area.

Further, the converging part is of a concave structure with a low middle and high periphery; the concave structure of the converging part is formed by combining a plurality of converging surfaces, and all the converging surfaces are intersected at a converging point.

Furthermore, a connecting channel is further arranged between the water absorbing area and the water tank area, and the water retaining ribs are parallel to the cross section of the connecting channel and are arranged at any axial position of the connecting channel.

Further, the converging surface is formed by combining and splicing a converging surface I, a converging surface II, a converging surface III and a converging surface IV which are all obliquely arranged, and the adjacent splicing surfaces all present an included angle with the degree of 174-178 degrees.

Further, the inclination directions of the first converging surface and the third converging surface incline from high to low from the water tank area to the converging part.

Further, the liquid level switch includes: the first-stage liquid level switch is suspended and fixed above the first water storage tank and is used for monitoring the water level of the first water storage tank; the second-stage liquid level switch is suspended and fixed above the second water storage tank and is used for monitoring the water level of the second water storage tank; when the water level of the water stored in the first water storage tank rises and the floater of the first-stage liquid level switch rises to reach a first-stage alarm position, a first-stage alarm signal is triggered; when the water level of the water stored in the second water storage tank rises and the floater of the secondary liquid level switch floats upwards to reach a secondary alarm position, a secondary alarm signal is triggered.

Further, the first water storage tank and the second water storage tank are different in depth.

Further, a groove is formed in the bottom of the water absorption area, and a filter assembly connected with the water pump is installed at the groove.

Further, a water blocking block is arranged between the converging part and the water beating area and separates the converging part from the water beating area, and the water blocking block is provided with a converging port which is staggered with the converging point, so that accumulated water is prevented from directly flowing into the water beating area from the converging point.

Compared with the prior art, the chassis structure has the following advantages:

(1) The water-absorbing area is isolated from the water tank area by the water retaining ribs, so that certain accumulated water can be stored in the water tank area, and when the condenser works, the accumulated water in the water tank area can be preferentially gathered to the water-spraying area and is sprayed onto fins of the condenser by the water-spraying wheels. On the other hand, by adopting the design of the water retaining ribs, the accumulated water can be effectively prevented from flowing backwards to the water absorption area, so that the phenomenon of insufficient condensed water in the water absorption area is caused when the water absorption wheel works, and unnecessary waiting time is generated; the collecting part is arranged, and before the accumulated water enters the water taking area, the accumulated water is preferentially introduced into the collecting part; the water retaining ribs are matched with the converging parts, so that the water on the chassis can be guided, and the water flows to the water spraying area preferentially; (2) The inclination directions of the first convergence surface and the third convergence surface incline from high to low from the water tank area to the convergence part, so that water at the water tank area is preferentially guided to the convergence part, and water on the chassis is preferentially flowed to the water taking area; (3) By adopting the secondary alarm mode, the problem that the air conditioner cannot be stopped in time when accumulated water is full can be effectively avoided, and potential safety hazards caused when the air conditioner is stopped suddenly from high-power operation can be avoided. The two-stage water level switch gives an alarm to control, so that the intelligent degree of movement control is increased, and the safety is enhanced;

(5) Through manger plate muscle, the portion of gathering, water storage tank, recess isotructure that set up on the chassis, can carry out reasonable planning to the water on the chassis, effectively schedule the comdenstion water and preferentially flow to the district of beating water from the basin district, secondly flow to water level control area, flow to the district of absorbing water at last to when the water yield is too much, carry out hierarchical warning, extension live time reduces down time.

Another object of the present invention is to provide a mobile air conditioner, which includes the chassis structure described above.

The air conditioner and the chassis structure have the same advantages as those of the prior art, and are not described in detail herein.

the water retaining rib 3926 is disposed at any axial position of the connecting channel 3925 parallel to the cross section of the connecting channel, and is used for isolating the water absorbing area 321 from the water tank area 322.

Furthermore, the concave structure of the converging portion 332 presents a round bottom pot-shaped structure, so that a part of accumulated water can be buffered in the converging portion 332 before the accumulated water enters the water pumping area 330; at the same time, the rate at which the accumulated water flows into the water-beating area 330 can be slowed. In addition, the round bottom design also avoids sediment accumulation at a point and is difficult to clean.

Preferably, a water blocking structure 3310 is arranged around the converging portion 332, the water blocking structure 3310 separates the water tank area 322 from the converging portion 332, the water blocking structure 3310 is provided with a plurality of water inlets 334, the water inlet 334 is arranged at a position of the converging portion 332 where the water level is higher than the converging point 333, the water inlet 334 is staggered from the converging point 333, and the water inlet 334 is staggered from the converging port 331.
