[0041] The mobile air conditioner 1 according to an embodiment of the present utility model will be described below with reference to the drawings.

[0042] As Figures 1-10 , the mobile air conditioner 1 according to an embodiment of the present utility model includes: a chassis 100, a housing 200, a refrigerant circulation circuit, an electrical box 700, and a power cord 10.

[0043] The housing 200 is installed on the chassis 100 to form a receiving space. A refrigerant circulation circuit is disposed in the receiving space and includes a compressor 300, a condenser 400, and an evaporator 600 connected end to end. One of the condenser 400 and the evaporator 600 is an outdoor heat exchanger, and the other is an indoor heat exchanger. The compressor 300 is installed on the chassis 100. An electric control box 700 is disposed in the receiving space, and an electric control board is installed in the electric control box 700. One end of a power cord 10 is connected to the electric control board.

[0044] The chassis 100 includes a bottom plate 102 and a chassis side plate 101 extending upward along the periphery of the bottom plate 102. Among them, the chassis side plate 101 is configured with an inclined plate portion 110 extending obliquely upward and inward. The housing 200 and the inclined plate portion 110 form a wire passing channel 112, and the power cord 10 passes through the wire passing channel 112 and extends out of the housing 200.

[0045] For example, the housing 200 is installed on the chassis 100. The housing 200 is provided with an outdoor air inlet 201, an outdoor air outlet 202, an indoor air inlet 203, and an indoor air outlet (not shown in the figure). The condenser 400 is fixed to the chassis 100 and corresponds to the position of the outdoor air inlet 201. An air duct member 500 is installed above the condenser 400. The evaporator 600 is installed above the air duct member 500 and corresponds to the position of the indoor air inlet 203. The electric control box 700 is installed on the chassis 100. The power cord 10 can be fixed to the inclined plate portion 110 through a wire clip or directly extend out of the housing 200 from the wire passing channel 112. The inclined plate portion 110 provides a guiding function for the power cord 10, and the power cord 10 extends out of the housing 200 from the wire passing channel 112 in an inclined direction.

[0046] The electric control box 700 is installed adjacent to the side of the inclined plate portion 110 of the chassis 100. The indoor air inlet 203, the outdoor air outlet 202, and the outdoor air inlet 201 face the same side of the housing 200. The chassis side plate 101 is disposed around the bottom surface of the chassis 100. The housing 200 is cooperatively limited and installed with the chassis side plate 101 through fasteners. The bottom of the housing 200 is provided with a wire passing hole or a wire passing notch suitable for the power cord 10 to pass through. When assembling the mobile air conditioner 1, the power cord 10 is first installed and fixed to the inclined plate portion 110 of the chassis 100, and the power cord 10 extends obliquely downward along the inclined plate portion 110. Then, the housing 200 and the chassis 100 are assembled. At this time, the chassis 100 and components such as the electric control box 700 thereon are covered by the housing 200. The bottom of the chassis 100 is configured with moving wheels, and the moving wheels space the chassis 100 from the ground and can drive the entire mobile air conditioner 1 to move.

[0047] According to the mobile air conditioner 1 of the embodiment of the present utility model, a sloping plate portion 110 inclined relative to the ground is constructed by a chassis apron 101. The sloping plate portion 110 can support a power cord 10 and guide the power cord 10 to extend out of a housing 200 along a direction inclined to the ground. The sloping plate portion 110 provides a fixed carrier for the power cord 10, so that the power cord 10 is fixed at the position where it extends out of the housing 200. When a user pulls the power cord 10, the power cord 10 can still be fixed to the chassis 100, avoiding loosening and power-off of the power cord 10.

[0048] And since the power cord 10 is inclined at a certain angle relative to the ground, the power cord 10 can extend substantially horizontally by relying on its own deformation outside the housing 200. Compared with the power cord 10 extending vertically downward, for the power cord 10 of the embodiment of the present utility model, when the user pulls the power cord 10, the portion of the power cord 10 outside the housing 200 is more easily pulled to a horizontal state, and the probability of the power cord 10 contacting the ground is smaller, reducing the risk of damage caused by wear of the power cord 10. Even when the power cord 10 contacts the ground when the bending radius is large, the force of the power cord 10 contacting the ground is smaller, the wear is smaller, and it will not be worn and skinned due to friction with the ground, thereby improving the service life and electrical safety.

[0049] In addition, the power cord 10 is installed on the sloping plate portion 110 through a wire clip 120. The installation surface of the wire clip 120 and the sloping plate portion 110 is inclined towards the outside of the housing 200. When the wire clip 120 and the sloping plate portion 110 are installed through fasteners, the installation tool for installing the fasteners can be installed obliquely outside the chassis 100 without vertically touching other components on the chassis 100. The installation process of the power cord 10 through the wire clip 120 is more in line with the ergonomic design, providing convenience for the installation of the wire clip 120 and the power cord 10.

[0050] Therefore, the mobile air conditioner 1 according to the embodiment of the present utility model has the advantages of firm fixation of the power cord 10, convenient assembly, reduced wear, etc.

[0051] In some specific embodiments of the present utility model, such as Figure 2As shown, the electrical box 700 is installed on one side of the chassis 100 adjacent to the inclined plate portion 110. The bottom of the electrical box 700 is supported by the bottom plate 102, thus preventing shaking and having better stability. For example, the electrical box 700 can be installed on the chassis enclosure 101. In this way, the electrical box 700 is relatively close to the inclined plate portion 110, and the routing distance of the power cord 10 can be shortened. Among them, the position of the electronic control board connected to one end of the power cord 10 is higher than the position of the wire passing channel 112. After the power cord 10 extends out of the electrical box 700 from the electronic control board, it first extends downward, then inclines along the inclined plate portion 110, and finally extends out of the housing 200. During the process of the power cord 10 leading out from the electronic control board of the electrical box 700 to the outside of the housing 200, there will be no large-angle bending, and the routing is relatively smooth.

[0052] As Figure 2 shown, the condenser 400 and the electrical box 700 are respectively located on adjacent side surfaces of the housing 200. There is a gap between the electrical box 700 and the condenser 400 to allow the power cord 10 to pass through, and the inclined plate portion 110 corresponds to the position of the gap between the electrical box 700 and the condenser 400.

[0053] For example, the electrical box 700 is configured as a box-shaped structure with a relatively thin thickness. Components such as capacitors and PCB boards are installed inside the electrical box 700. The condenser 400 is arranged parallel to one side surface of the housing 200, and the electrical box 700 is arranged parallel to another side surface of the housing 200. Thus, the condenser 400 and the electrical box 700 are arranged perpendicular to each other on adjacent sides of the chassis 100. In this way, there can be a relatively large space at the center of the chassis 100 for arranging the compressor 300, and the space utilization is more reasonable.

[0054] Moreover, the condenser 400 and the electrical box 700 are respectively located on adjacent sides of the chassis 100 and are perpendicular to each other. The condenser 400 and the electrical box 700 have the same height, and can play a certain supporting role for the air duct member 500 and the evaporator 600 above. Specifically, the compressor 300 and the electrical box 700 are supported at three corners of the chassis 100. Columns are provided for support at the positions of the chassis 100 where there is no support from the compressor 300 and the electrical box 700. Thus, while the condenser 400 and the electrical box 700 meet the heat exchange and power consumption requirements, they also form an auxiliary installation and support structure, reducing the use of additional structural parts and reducing the weight of the mobile air conditioner 1. In addition, due to the gap between the electrical box 700 and the condenser 400, space can be provided for the routing of the power cord 10, and the power cord 10 will not be squeezed or worn by other components, and the routing arrangement is more reasonable.

[0055] In some specific embodiments of the present invention, as Figure 6 shown, the chassis enclosure 101 is configured with a enclosure recess 111 recessed towards the center of the chassis 100 at the position of the inclined plate portion 110, and the inclined plate portion 110 is connected inside the enclosure recess 111.

[0056] The enclosure recess 111 is formed by the chassis enclosure 101, and the inclined plate portion 110 is connected inside the enclosure recess 111, so that the wire clamp 120 and the inclined portion are kept inside the outer contour of the chassis 100. Thus, when the housing 200 is covered, the housing 200 can hide the wire clamp 120 inside the housing 200, and the bending point of the power cord 10 is also inside the outer contour of the chassis enclosure 101. The part of the power cord 10 extending out of the housing 200 can extend in a more horizontal direction, which is more neat and beautiful. In addition, since the bending point of the power cord 10 is prone to wear, by fixing the power cord 10 inside the enclosure recess 111, it can also play a certain protective role for the power cord 10.

[0057] In some specific embodiments of the present utility model, as Figure 5 shown, the included angle between the inclined plate portion 110 and the bottom plate 102 is 30° to 70°. Within this range, on the one hand, installation tools such as screwdrivers can be tilted at an appropriate angle to disassemble and assemble the wire clamp 120, avoiding interference with other components on the chassis 100 during the disassembly and assembly process. On the other hand, it can provide an appropriate guiding angle for the power cord 10, and the power cord 10 extends downward out of the housing 200 at an appropriate inclined angle, preventing the power cord 10 from having an excessive bending radius and contacting and wearing the ground.

[0058] In some specific embodiments of the present utility model, as Figure 7 shown, the power cord 10 is installed on the inclined plate portion 110 through the wire clamp 120. The wire clamp 120 includes: a surrounding portion 121, a first mounting edge 122, and a second mounting edge 123.

[0059] The surrounding portion 121 surrounds the power cord 10. The first mounting edge 122 is connected to one end of the surrounding portion 121, and the second mounting edge 123 is connected to the other end of the surrounding portion 121. The first mounting edge 122 and the second mounting edge 123 are stacked and jointly penetrated by a fastener to be fixed to the inclined plate portion 110.

[0060] Among them, the wire clamp 120 is an elastic member, and the surrounding portion 121 adapts and fits power cords 10 with different diameters through its own elastic deformation. The first mounting edge 122 and the second mounting edge 123 are connected to the same side of the surrounding portion 121 and are fixed to the inclined plate portion 110 by penetrating a fastener, so that the wire clamp 120 clamps the power cord 10 tightly on the inclined plate portion 110.

[0061] For example, the second mounting edge 123 can be pre-fixed to the inclined plate portion 110 by one of the fasteners. Relying on the surrounding portion 121 to clamp the power cord 10 tightly, and making the first mounting edge 122 stacked above the second mounting edge 123. The first mounting edge 122 and the second mounting edge 123 jointly penetrate a fastener to be fixed to the inclined plate portion 110, so that the power cord 10 is fixed to the chassis 100.

[0062] Further, as Figure 7 shown, one of the first mounting edge 122 and the second mounting edge 123 is configured with a circular hole 124 and the other is configured with an oblong hole 125. The circular hole 124 and the oblong hole 125 are adapted to jointly pass through a fastener and be fixed to the inclined plate portion 110.

[0063] For example, the second mounting edge 123 is configured with a circular hole 124, and the first mounting edge 122 is configured with an oblong hole 125. When installing the wire harness, the oblong hole 125 and the circular hole 124 are aligned with each other, and the position is adjusted by adjusting the surrounding portion 121 to adapt to the diameter of the power cord 10. At the same time, the first mounting edge 122 and the second mounting edge 123 are adjusted in the mounting position along the adjustment direction, so that the oblong hole 125 of the first mounting edge 122 can jointly pass through the fastener with the circular hole 124 of the second mounting edge 123 at different positions, thereby adapting to the installation of power cords 10 with different diameters.

[0064] In some specific embodiments of the present utility model, as Figure 8 shown, the mobile air conditioner 1 further includes: a water pumping assembly 800. The water pumping assembly 800 is fixed to the chassis 100. The water pumping assembly 800 includes a water pumping motor 810 and an impeller 820. The water pumping motor 810 is electrically connected to the electrical box 700. The chassis 100 is configured with a water collecting tank 12 and a water receiving pool 11 communicating with the water collecting tank 12. The condenser 400 is installed in the water collecting tank 12, and the impeller 820 extends into the water collecting tank 12.

[0065] Wherein, the compressor 300, the condenser 400 and the electrical box 700 are arranged around the water pumping motor 810. The condenser 400 is installed in the water collecting tank 12. When the mobile air conditioner 1 operates in the cooling mode, the upper evaporator 600 generates condensed water, which flows along the evaporation pipeline to the lower chassis 100. During the operation of the lower condenser 400, a relatively high heat is generated. The water pumping assembly 800 drives the impeller 820 to rotate through the water pumping motor 810, and conveys the condensed water in the water collecting tank 12 to the condenser 400. By using the heat of the condenser 400, the condensed water at the chassis 100 can be quickly evaporated, ensuring that the condensed water at the chassis always remains at a relatively low water level and avoiding too high a water level.

[0066] Further, as Figure 3 shown, the chassis 100 is configured with a water receiving pool 11. The water receiving pool 11 includes: a first water receiving pool 13 and a second water receiving pool 14.

[0067] The first water receiving pool 13 is located on the side of the compressor 300 facing the electrical box 700. The impeller 820 extends into the first water receiving pool 13. The first water receiving pool 13 communicates with one side of the water collecting tank 12. The second water receiving pool 14 is located on the side of the compressor 300 facing away from the electrical box 700. The second water receiving pool 14 communicates with the other side of the water collecting tank 12.

[0068] By separating the water receiving tank 11 into at least two parts, the condensed water on the chassis 100 can be dispersed, preventing the condensed water from concentrating on one side of the chassis 100. Moreover, the first water receiving tank 13 and the second water receiving tank 14 are respectively connected to both sides of the water collecting tank 12. This can prevent the condensed water from concentrating too much when the air conditioner is tilted. In addition, the first water receiving tank 13 and the second water receiving tank 14 are arranged around the compressor 300, making full use of the space of the chassis 100 to collect the condensed water, and the water pumping assembly 800 pumps water to the condenser 400 to evaporate the condensed water in the water receiving tank 11 in time, improving the evaporation efficiency of the condensed water.

[0069] Furthermore, as Figure 9 and Figure 10 shown, a downward extending flanging 701 is constructed on the outer side of the bottom of the electrical box 700. The flanging 701 is installed on the inner side of the chassis enclosing plate 101 of the chassis 100 and the bottom surface of the electrical box 700 is located above the first water receiving tank 13.

[0070] The electrical box 700 is constructed with the flanging 701, which can keep the bottom surface of the electrical box 700 above the first water receiving tank 13 and at an interval from the first water receiving tank 13. The first water receiving tank 13 can make full use of the space at the bottom of the electrical box 700 and has a larger capacity. Moreover, the bottom surface of the electrical box 700 is kept above the first water receiving tank 13, preventing the condensed water in the first water receiving tank 13 from affecting the electrical components in the electrical box 700 and ensuring the electrical safety.

[0071] In some specific embodiments of the present utility model, as Figure 4 , Figure 8 shown, the mobile air conditioner 1 further includes: a water level switch 900. The chassis 100 is constructed with a water level switch bracket 901 above the second water receiving tank 14. The water level switch 900 is installed on the water level switch bracket 901, and the water level switch 900 extends into the second water receiving tank 14 to measure the water level height.

[0072] Since both the first water receiving tank 13 and the second water receiving tank 14 are communicated with the water collecting tank 12, the water level heights of the first water receiving tank 13, the second water receiving tank and the water collecting tank 12 are the same. And there is an electrical box 700 above the first water receiving tank 13. By constructing a water level switch extending into the second water receiving tank 14 above the second water receiving tank 14, the water level information can be obtained in time, the water level height can be measured in time, and the machine can be stopped when the water level is too high, ensuring the safety of using the mobile air conditioner 1.

[0073] Other constitutions and operations according to the embodiments of the present utility model are known to those of ordinary skill in the art and will not be described in detail here.

[0074] In this application, the air conditioner performs a refrigeration cycle by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0075] The compressor compresses the refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0076] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to perform a heat exchange with the material to be cooled. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0077] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger. The indoor unit of the air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0078] The indoor heat exchanger and the outdoor heat exchanger serve as condensers or evaporators. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in the heating mode. When the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in the cooling mode.
