[0002] When a mobile air conditioner operates, condensed water will be generated. A water storage tank and a water pumping member are arranged below the condenser. The water storage tank can receive and collect the condensed water, and the water pumping member can stir the condensed water and transport it to the outdoor heat exchanger to cool the outdoor heat exchanger. A float switch is arranged in the water storage tank to monitor the water level in the water storage tank, so that the water pumping member can automatically operate when the set water level is reached, or the water pumping member can stop operating when the water level is lower than the set water level.

[0003] The existing float switches are often fixed by means of screws and upper and lower nuts. Such fixation not only has cumbersome steps and is not convenient for disassembly, but also the condensed water will cause the screws to rust, affecting the accuracy of the float switch in monitoring the water level.

A protruding portion 401 is provided on the inner side surface of the limiting member 400, and the protruding portion 401 abuts against the upper side surface of the top cover plate 520.

[0052] Optionally, the chassis can be used in a mobile air conditioner. The mobile air conditioner includes a housing 10. The interior of the housing 10 is hollow, and the bottom end is provided as an open end. The disk body 100 of the chassis is arranged at the open end, and the chassis and the housing 10 jointly enclose a cavity for air flow. Among them, a middle partition is provided in the housing 10, and the middle partition, the chassis, and the housing jointly enclose a flow space for the air flowing through the outdoor heat exchanger 710. An indoor heat exchanger is provided on the middle partition, and an outdoor heat exchanger 710 is provided on the disk body 100 of the chassis.

[0053] In the cooling mode of a mobile air conditioner, a large amount of condensed water is generated by the indoor heat exchanger, and the outdoor heat exchanger 710 needs to dissipate heat as a condenser. A water storage tank 110 corresponding to the outdoor heat exchanger 710 is provided on the chassis. The condensed water generated by the indoor heat exchanger can be diverted into the water storage tank 110. The water storage tank 110 is communicated with the installation groove 200, and the water levels inside the two are the same. Optionally, a water splashing part 120 is provided in the water storage tank 110. When the water in the water storage tank 110 reaches a preset height, the water splashing part 120 can be started to stir the condensed water and splash it onto the outdoor heat exchanger 710 to cool the outdoor heat exchanger 710, improve the heat exchange efficiency of the outdoor heat exchanger 710, and extend the service life of the outdoor heat exchanger 710.

[0054] Optionally, the disk body 100 is placed horizontally, and an installation groove 200 is formed on the disk body 100, and condensed water can be stored in the installation groove 200. By arranging a float assembly 500 in the installation groove 200, the float assembly 500 can be used to detect the water levels in the installation groove 200 and the water storage tank 110.

[0055] Optionally, the float assembly 500 includes a guide rod 510 and a top cover plate 520.

The first float 530 is sleeved on the guide rod 510 and is located below the second float 540. The first float 530 moves up or down as the water level height in the installation groove 200 changes. When the first float 530 is in contact with the second float 540, a signal will be sent to the mobile air conditioner, so that the operation of the water splashing part 120 can be controlled to cool the outdoor heat exchanger 710 and improve the heat exchange efficiency of the outdoor heat exchanger 710.

[0056] Optionally, an installation assembly for the float assembly 500 is provided in the installation groove 200. The installation assembly includes a positioning part 300 and a limiting part 400.

[0096] Alternatively, the extension plate 551 is not provided.

[0097] In the alternative embodiment of the above chassis, it further includes a surrounding baffle 640. The surrounding baffle 640 is fixedly disposed at the top end of the fourth side wall of the groove 240 and is disposed close to the end portion in the length direction of the fourth side wall of the groove 240. The surrounding baffle 640 includes a first plate body 641 and a second plate body 642 which are bent and connected, and both the first plate body 641 and the second plate body 642 abut against the side cover plate 550.

[0098] By providing the surrounding baffle 640, the surrounding and limiting of the side end of the top cover plate 520 facing the fourth side wall of the groove and the side cover plate 550 can be realized, and the limiting effect on the top cover plate 520 and the side cover plate 550 can be improved.

[0099] Alternatively, the surrounding baffle 640 may not be provided.

[0100] Optionally, the surrounding baffle 640 may be fixedly connected to the positioning plate 310.

[0101] In the alternative embodiment of the above chassis, the support block 630 is fixedly connected to the first plate body 641, and / or, the support block 630 is fixedly connected to the second plate body 642.

[0102] In this way, through the fixed connection between the first plate body 641 and / or the second plate body 642 and the support block 630, the baffle 640 and the support block 630 can support each other, improving the structural stability.

[0103] Optionally, the support block 630 and the baffle 640 are integrally formed. Alternatively, the support block 630 and the baffle 640 are fixedly connected by means such as gluing.

[0104] Optionally, the support block 630 and the fourth side groove wall 240 are integrally formed. Alternatively, the support block 630 and the fourth side groove wall 240 are fixedly connected by means such as gluing.

[0105] The baffle 640 and the fourth side groove wall 240 are integrally formed. Alternatively, the baffle 640 and the fourth side groove wall 240 are fixedly connected by means such as gluing.

[0106] In a second aspect, the present utility model provides a mobile air conditioner, including a housing 10, the chassis as described above, and an outdoor heat exchanger 710. An opening is configured at the bottom end of the housing 10, the chassis is fixed to the opening, and a water storage tank 110 communicating with the installation groove 200 is further provided on the disk body 100 of the chassis; the outdoor heat exchanger 710 is arranged corresponding to the water storage tank 110 on the disk body 100.

[0107] In the case of adopting the above technical solution, the chassis is arranged at the opening at the bottom of the housing, and a water storage tank communicating with the installation groove is provided. The water storage tank and the outdoor heat exchanger are arranged corresponding to each other, and the water levels in the water storage tank and the installation groove are the same. The float assembly obtains the water level in the water storage tank by detecting the water level in the installation groove. By the support portion of the positioning member in the installation groove abutting against the lower side surface of the top cover plate, the installation positioning of the float assembly can be realized. At the same time, the protruding portion of the limiting member abutting against the upper side surface of the top cover plate can realize the limitation of the top cover plate. The support portion and the protruding portion can realize the clamping of the top cover plate, thereby realizing the installation of the float assembly. In this solution, it is only necessary to clamp the top cover plate between the support portion and the protruding portion, so that the installation difficulty of the float assembly can be reduced and the installation efficiency can be improved; and the problem of rusting caused by screw installation can be avoided, and the accuracy of the float assembly for monitoring the water level of the water storage tank provided corresponding to the outdoor heat exchanger can be ensured.
