[0051] The mobile air conditioner 1 according to the embodiments of the present application is described below with reference to the drawings.

[0052] As shown in Figures 1-11 According to the embodiments of the present application, the mobile air conditioner 1 can include a casing 100, the casing 100 is provided with an indoor air inlet 110 and an indoor air outlet 120, indoor air can enter the casing 100 through the indoor air inlet 110 and flow back to the indoor through the indoor air outlet 120.

[0053] In addition, the casing 100 can also be provided with an outdoor air inlet 130 and an outdoor air outlet 140, outdoor air can enter the casing 100 through the outdoor air inlet 130 and flow back to the outdoor through the outdoor air outlet 140.

[0054] The mobile air conditioner 1 can include an indoor heat exchanger 200, the indoor heat exchanger 200 is arranged in the casing 100, after the indoor air enters the casing 100 through the indoor air inlet 110, the indoor air can exchange heat with the indoor heat exchanger 200, for example, the refrigerant flowing through the indoor heat exchanger 200 can absorb the heat of the air to reduce the temperature of the air, thereby cooling the indoor, or the refrigerant flowing through the indoor heat exchanger 200 can release heat to the air to increase the temperature of the air, thereby heating the indoor.

[0055] The mobile air conditioner 1 can include an indoor fan arranged in the casing 100, the indoor fan driving indoor air to flow into the casing 100 from the indoor air inlet 110 and flow back to the indoor environment from the indoor air outlet 120 after heat exchange with the indoor heat exchanger 200, the indoor fan can guide the flow of the indoor air to accelerate the flow rate of the indoor air flowing into the casing 100 from the indoor air inlet 110 and flowing back to the indoor environment from the indoor air outlet 120, thereby improving the heat exchange efficiency of the indoor air and the indoor heat exchanger 200.

[0056] The mobile air conditioner 1 can include an outdoor heat exchanger 300 arranged in the casing 100, outdoor air can enter the casing 100 through the outdoor air inlet 130 and exchange heat with the refrigerant of the outdoor heat exchanger 300. For example, when the mobile air conditioner 1 is indoor cooling, the high-temperature refrigerant flowing out of the compressor can first flow to the outdoor heat exchanger 300 and release heat to the outdoor air through the outdoor heat exchanger 300, and then flow to the indoor heat exchanger 200 after the temperature of the refrigerant is reduced, so as to absorb the heat of the indoor air through the indoor heat exchanger 200, thereby reducing the temperature of the indoor air and achieving indoor cooling. When the mobile air conditioner 1 is indoor heating, the high-temperature refrigerant flowing out of the compressor can first flow to the indoor heat exchanger 200, the high-temperature refrigerant releases heat to the indoor air through the indoor heat exchanger 200 to increase the indoor temperature, thereby achieving indoor heating, and then the refrigerant flows to the outdoor heat exchanger 300 after the temperature of the refrigerant is reduced, and absorbs the heat of the outdoor air through the outdoor heat exchanger 300, and then the temperature of the refrigerant is increased and flows back to the compressor, completing the heating cycle.

[0057] The mobile air conditioner 1 can include an air duct 400 arranged in the casing 100, and the air duct 400 is in communication with the outdoor air inlet 130 and the outdoor air outlet 140, respectively, and the air duct 400 can guide the outdoor air flowing into the casing 100 to flow more orderly in the casing 100.

[0058] The mobile air conditioner 1 can include an outdoor fan 510 arranged in the air duct 400, the outdoor fan 510 drives outdoor air to flow into the casing 100 from the outdoor air inlet 130 and flow back to the outdoor environment from the outdoor air outlet 140 after heat exchange with the outdoor heat exchanger 300, that is, the outdoor fan 510 can guide the flow of the outdoor air to accelerate the flow rate of the outdoor air flowing into the casing 100 from the outdoor air inlet 130 and flowing back to the outdoor environment from the outdoor air outlet 140, thereby improving the heat exchange efficiency of the outdoor air and the outdoor heat exchanger 300. The outdoor fan 510 can be a centrifugal fan.

[0059] The mobile air conditioner 1 can include an electric control component 600 arranged in the casing 100 and located at the lower side of the outdoor fan 510. The electric control component 600 can be electrically connected with the compressor, the indoor fan and the outdoor fan 510.

[0060] Specifically, the electric control component 600 can include an electric control box 610 provided with a heat dissipation inlet 613 and a heat dissipation outlet 612, so that air can flow into the electric control box 610 through the heat dissipation inlet 613 and flow out of the electric control box 610 through the heat dissipation outlet 612. The air flow through the inside of the electric control box 610 can take away the heat in the electric control box 610, thereby reducing the temperature inside the electric control box 610 and avoiding the temperature of the electric control component 600 being too high.

[0061] The electric control component 600 can further include an electric control board 620 arranged in the electric control box 610. The electric control box 610 can provide a mounting position for the electric control board 620 and protect the electric control board 620. When the air flow flows through the inside of the electric control box 610, the heat of the electric control board 620 can be taken away, thereby avoiding the temperature of the electric control board 620 being too high and enabling the electric control board 620 to operate normally.

[0062] Specifically, when the mobile air conditioner 1 operates, the outdoor fan 510 rotates, thereby generating negative pressure in the negative pressure space 520, i.e. suction force is generated in the negative pressure space 520. The suction force can suck air flow from the outdoor heat exchanger 300 and the electric control box 610 into the air duct 400 and discharge the air flow outside. That is, the mobile air conditioner 1 can generate forced convection in the electric control box 610 by using the negative pressure in the negative pressure space 520, so that more air can flow into the electric control box 610 from the heat dissipation inlet 613 and then flow to the negative pressure space 520 from the heat dissipation outlet 612. The air flow through the inside of the electric control box 610 can be greater, thereby taking away the heat of the electric control board 620 by using the flowing air flow, avoiding the temperature of the electric control component 600 being too high and improving the heat dissipation effect of the electric control component 600.

[0063] Moreover, in the mobile air conditioner 1, the heat dissipation outlet 612 can be directly communicated with the negative pressure space 520, so that the heat dissipation outlet 612 is not blocked by other components, thereby more effectively generating forced convection in the electric control box 610 by using the suction force generated in the negative pressure space 520, further improving the air flow of the electric control box 610 and improving the heat dissipation effect of the electric control component 600 by the flowing air flow.

[0064] In addition, the heat of the electric control component 600 is taken away by the flowing air current, the heat dissipation effect of the electric control component 600 is good, and thus, too many heat dissipation holes do not need to be arranged on the electric control box 610, the electric control box 610 is convenient to process, the sealing property, the fireproof property and the rainproof property of the electric control box 610 are improved, and even if the electric control component 600 is on fire, the probability of fire spreading can be effectively reduced.

[0065] Therefore, the mobile air conditioner 1 can accelerate the air flow rate in the electric control box 610 by using the negative pressure formed by the negative pressure space 520, and then can form forced convection in the electric control box 610, so as to dissipate heat and cool the electric control component 600 by using the air current, and the heat dissipation effect of the electric control component 600 is improved.

[0066] In some specific embodiments of the utility model, as shown in Figure 3 The air duct piece 400 can include a first air duct piece 410, and the lower side of the first air duct piece 410 is mounted to the cabinet 100, that is, the first air duct piece 410 is arranged inside the cabinet 100 and adjacent to the lower part of the cabinet 100.

[0067] As shown in Figure 3 The air duct piece 400 can include a second air duct piece 420, and the second air duct piece 420 is arranged on one side of the first air duct piece 410, and the electric control component 600 is arranged on one side of the first air duct piece 410 and located on the lower side of the second air duct piece 420. For example, the second air duct piece 420 can be arranged on the side of the first air duct piece 410 away from the outdoor heat exchanger 300, and the electric control component 600 and the second air duct piece 420 can be located on the same side of the first air duct piece 410.

[0068] The second air duct piece 420 and the first air duct piece 410 are connected to form a cavity for mounting the outdoor fan 510.

[0069] The first air duct piece 410 is provided with a communication hole 413, and the heat dissipation outlet 612 communicates with the negative pressure space 520 through the communication hole 413. In this way, the first air duct piece 410 does not cut off the negative pressure space 520 and the heat dissipation outlet 612, so that the suction force generated in the negative pressure space 520 can act on the electric control box 610 through the communication hole 413 and the heat dissipation outlet 612, thereby generating forced convection in the electric control box 610 to take away the heat of the electric control board 620, and the heat dissipation efficiency of the electric control component 600 is improved.

[0070] In some specific embodiments of the utility model, as shown in Figure 8 And Figure 9As shown, the electric control box 610 is provided with an air outlet ring platform 611 which protrudes from the side of the electric control box 610 facing the first air duct piece 410, and a heat dissipation outlet 612 is configured on the air outlet ring platform 611, and the air outlet ring platform 611 extends into the communication hole 413.

[0071] The air outlet ring platform 611 can extend along the circumference of the communication hole 413, and the outer contour of the air outlet ring platform 611 can be matched with the outer contour of the communication hole 413, so as to facilitate the extension of the air outlet ring platform 611 into the communication hole 413, and the relative positioning of the electric control box 610 and the first air duct piece 410 can be realized through the cooperation of the air outlet ring platform 611 and the communication hole 413.

[0072] Moreover, the outer side wall of the air outlet ring platform 611 can be matched with the inner wall of the communication hole 413, which is conducive to improving the sealing performance of the heat dissipation outlet 612 and the communication hole 413, avoiding air leakage, so that the negative pressure in the negative pressure space 520 can be more effectively utilized to generate suction force in the electric control box 610 to generate flowing air in the electric control box 610, thereby improving the heat dissipation effect of the electric control component 600. Of course, in order to facilitate the assembly of the electric control box 610 and the first air duct piece 410, the outer side wall of the air outlet ring platform 611 and the inner wall of the communication hole 413 can also be matched with a gap.

[0073] In some specific embodiments of the present application, as shown in Figures 3-6 The mobile air conditioner 1 can further include a water collecting tray 700.

[0074] The water collecting tray 700 is arranged on the lower side of the outdoor heat exchanger 300, and the side of the first air duct piece 410 facing the outdoor heat exchanger 300 is provided with a wind guide rib 411 which extends along the circumference of the communication hole 413, and the wind guide rib 411 and the water collecting tray 700 jointly define a wind guide channel 710 which is in communication with the communication hole 413 and the negative pressure space 520 respectively.

[0075] By arranging the wind guide rib 411, the structural strength of the first air duct piece 410 around the communication hole 413 can be improved by the wind guide rib 411, and the wind guide channel 710 is defined by the wind guide rib 411 and the water collecting tray 700, which is simple in structure and can guide the air through the wind guide channel 710, so as to facilitate the flowing air in the electric control box 610 to flow into the negative pressure space 520.

[0076] Specifically, when the mobile air conditioner 1 is working, the outdoor fan 510 is running, and negative pressure is generated in the negative pressure space 520, and under the action of the negative pressure, the flowing air current is forced to be generated in the electric control box 610, that is, the air can flow into the electric control box 610 from the heat dissipation inlet 613, and then flow into the negative pressure space 520 through the heat dissipation outlet 612, the communication hole 413 and the air guide channel 710 in sequence after flowing through the electric control panel 620 and taking away the heat of the electric control panel 620, and finally can be driven to be discharged to the outside through the outdoor fan 510, so that the heat dissipation efficiency of the electric control panel 620 can be improved.

[0077] In some specific examples of the utility model, as shown in

[0078] That is, the communication hole 413 and the negative pressure space 520 can be communicated through the air guide pipe, that is, one end of the air guide pipe is connected with the communication hole 413, and the other end of the air guide pipe is communicated with the negative pressure space 520, so that the communication hole 413 and the negative pressure space 520 can be communicated through the air guide pipe, and the sealing effect and the air guide effect can be better, so that the flowing air current in the electric control box 610 can flow into the negative pressure space 520 smoothly, and the heat dissipation efficiency of the electric control component 600 can be improved.

[0079] In some specific examples of the utility model, as shown in Figures 7-11 The heat dissipation inlet 613 is adjacent to the lower side of the electric control box 610, and the heat dissipation outlet 612 is adjacent to the upper side of the electric control box 610.

[0080] Therefore, the air can flow into the electric control box 610 through the heat dissipation inlet 613 on the lower side, and then flow out of the electric control box 610 from the heat dissipation outlet 612 on the upper side, that is, the air can keep the flowing direction of "entering from the lower side and flowing out from the upper side", so that the flowing air current in the electric control box 610 can flow through the electric control panel 620 better, the contact area between the flowing air current and the electric control panel 620 can be larger, so that the heat of the electric control panel 620 can be taken away more effectively by the flowing air current, and the heat dissipation effect of the electric control panel 620 can be improved.

[0081] In some specific examples of the utility model, as shown in Figure 3 And Figure 4 The first air duct part 410 is provided with a ventilation grille 412, the first air duct part 410 and the shell 100 define a heat dissipation air inlet channel 160, the ventilation grille 412 is communicated with the outdoor air inlet 130 through the heat dissipation air inlet channel 160, and the heat dissipation inlet 613 is communicated with the ventilation grille 412.

[0082] That is, the ventilation grating 412 is in communication with the heat dissipation inlet 613 and the outdoor air inlet 130 respectively, so that the first air duct member 410 does not completely cover the heat dissipation inlet 613, and outdoor air can flow to the heat dissipation inlet 613 through the heat dissipation air inlet channel 160 and the ventilation grating 412, so that outdoor air can flow into the electric control box 610, and then the outdoor air can be used to heat dissipation and cooling of the electric control board 620 in the electric control box 610.

[0083] Specifically, the outdoor air can enter the electric control box 610 through the outdoor air inlet 130, the heat dissipation air inlet channel 160, the ventilation grating 412 and the heat dissipation inlet 613 in turn, and then the outdoor air can flow upward along the up-down direction and flow out of the electric control box 610 through the heat dissipation outlet 612, and finally flow to the negative pressure space 520 through the air guide channel 710 and be discharged to the outside under the drive of the outdoor fan 510.

[0084] In some specific examples of the present application, as shown in Figure 6 and Figure 7 The electric control component 600 can further include a heat sink 630 connected to the electric control board 620, and the heat sink 630 is exposed from the heat dissipation inlet 613 and adjacent to the ventilation grating 412.

[0085] In this way, the heat sink 630 can be close to the ventilation grating 412, and when the outdoor air flows to the heat dissipation inlet 613 through the ventilation grating 412, it can ensure that part of the airflow can flow through the heat sink 630, and then the flowing air can carry away the heat on the heat sink 630, thereby improving the heat dissipation efficiency of the heat sink 630 on the electric control board 620.

[0086] In some specific examples of the present application, as shown in Figure 7 and Figure 8 The heat dissipation inlet 613 can include a first inlet 614, and the first inlet 614 is arranged on the side of the electric control box 610 facing the first air duct member 410, and the first inlet 614 is adjacent to the ventilation grating 412, and the heat sink 630 is exposed from the first inlet 614.

[0087] That is, the first inlet 614 can be in communication with the outdoor air inlet 130 through the ventilation grating 412, so that outdoor air can flow into the electric control box 610 through the first inlet 614 to heat dissipation and cooling of the electric control component 600.

[0088] In addition, the heat dissipation inlet 613 can include a second inlet 615, and the second inlet 615 is arranged on one side of the electric control box 610 in the width direction, and the second inlet 615 is adjacent to the air inlet grating 150. For example, the first inlet 614 and the second inlet 615 can be arranged on two adjacent sides of the electric control box 610.

[0089] In this way, the indoor air can flow into the electric control box 610 in sequence through the air inlet grille 150 and the second inlet 615, so as to use the indoor air to cool the electric control components 600.

[0090] Therefore, by arranging the first inlet 614 and the second inlet 615, the air inlet amount of the electric control box 610 can be increased, and more flow air current can be generated in the electric control box 610, which is beneficial to improve the heat dissipation efficiency of the flow air current on the electric control components 600, and the heat dissipation effect is better.

[0091] The mobile air conditioner 1 according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0092] As shown in the drawings, Figures 1-11 The mobile air conditioner 1 can include a cabinet 100, the cabinet 100 is provided with an indoor air inlet 110 and an indoor air outlet 120, the indoor air can enter the cabinet 100 through the indoor air inlet 110 and flow back to the indoor through the indoor air outlet 120.

[0093] In addition, the cabinet 100 can also be provided with an outdoor air inlet 130 and an outdoor air outlet 140, the outdoor air can enter the cabinet 100 through the outdoor air inlet 130 and flow back to the outdoor through the outdoor air outlet 140.

[0094] The mobile air conditioner 1 can include an indoor heat exchanger 200, the indoor heat exchanger 200 is arranged in the cabinet 100, and the indoor air can exchange heat with the indoor heat exchanger 200 after entering the cabinet 100 through the indoor air inlet 110, for example, the refrigerant flowing through the indoor heat exchanger 200 can absorb the heat of the air to reduce the temperature of the air, thereby cooling the indoor, or the refrigerant flowing through the indoor heat exchanger 200 can release heat to the air to increase the temperature of the air, thereby heating the indoor.

[0095] The mobile air conditioner 1 can include an indoor fan, the indoor fan is arranged in the cabinet 100, the indoor fan drives the indoor air to enter the cabinet 100 from the indoor air inlet 110, and the indoor air flows back to the indoor through the indoor air outlet 120 after exchanging heat with the indoor heat exchanger 200, the indoor fan can guide the flow of the indoor air to accelerate the flow rate of the indoor air flowing into the cabinet 100 from the indoor air inlet 110 and flowing back to the indoor from the indoor air outlet 120, thereby improving the heat exchange efficiency of the indoor air and the indoor heat exchanger 200.

[0096] The mobile air conditioner 1 can include an outdoor heat exchanger 300 arranged in the casing 100, and outdoor air can enter the casing 100 through the outdoor air inlet 130 and exchange heat with the refrigerant of the outdoor heat exchanger 300. For example, when the mobile air conditioner 1 is used for indoor cooling, the high-temperature refrigerant flowing out of the compressor can first flow to the outdoor heat exchanger 300, and release heat to the outdoor air through the outdoor heat exchanger 300, so that the temperature of the refrigerant is reduced, and then the refrigerant flows to the indoor heat exchanger 200 to absorb heat from the indoor air through the indoor heat exchanger 200, so that the temperature of the indoor air is reduced, thereby achieving indoor cooling. When the mobile air conditioner 1 is used for indoor heating, the high-temperature refrigerant flowing out of the compressor can first flow to the indoor heat exchanger 200, and the high-temperature refrigerant releases heat to the indoor air through the indoor heat exchanger 200, so that the indoor temperature is increased, thereby achieving indoor heating, and then the temperature of the refrigerant is reduced, and then the refrigerant flows to the outdoor heat exchanger 300 to absorb heat from the outdoor air through the outdoor heat exchanger 300, so that the temperature of the refrigerant is increased, and then the refrigerant flows back to the compressor, thereby completing the heating cycle.

[0097] The mobile air conditioner 1 can include an air duct 400 arranged in the casing 100, and the air duct 400 is in communication with the outdoor air inlet 130 and the outdoor air outlet 140, respectively. The air duct 400 can guide the outdoor air to flow more orderly in the casing 100.

[0098] The mobile air conditioner 1 can include an outdoor fan 510 arranged in the air duct 400. The outdoor fan 510 drives the outdoor air to flow from the outdoor air inlet 130 into the casing 100, and the outdoor air flows back to the outdoor air after exchanging heat with the outdoor heat exchanger 300 through the outdoor air outlet 140. That is, the outdoor fan 510 can guide the flow of outdoor air to increase the flow rate of outdoor air flowing from the outdoor air inlet 130 into the casing 100 and flowing back to the outdoor air from the outdoor air outlet 140, thereby improving the heat exchange efficiency between the outdoor air and the outdoor heat exchanger 300. The outdoor fan 510 can be a centrifugal fan.

[0099] The mobile air conditioner 1 can include an electric control component 600 arranged in the casing 100 and located below the outdoor fan 510. The electric control component 600 can be electrically connected with the compressor, the indoor fan and the outdoor fan 510.

[0100] Specifically, the electric control component 600 can include an electric control box 610 provided with a heat dissipation inlet 613 and a heat dissipation outlet 612. In this way, air can flow into the electric control box 610 through the heat dissipation inlet 613, and flow out of the electric control box 610 through the heat dissipation outlet 612. The air flowing through the inside of the electric control box 610 can carry away the heat in the electric control box 610, thereby reducing the temperature inside the electric control box 610 and avoiding the temperature of the electric control component 600 being too high.

[0101] The electric control component 600 can further include an electric control board 620 arranged in the electric control box 610, the electric control box 610 can provide a mounting position for the electric control board 620 and protect the electric control board 620. When the air flow flows through the inside of the electric control box 610, the heat of the electric control board 620 can be taken away, so that the temperature of the electric control board 620 can be prevented from being too high, so that the electric control board 620 can normally operate.

[0102] The side of the air duct piece 400 facing the outdoor heat exchanger 510 is provided with an air duct air inlet 430, and the heat dissipation outlet 612 is in communication with the air duct air inlet 430. In this way, when the mobile air conditioner 1 operates, the outdoor fan 510 rotates, and then negative pressure can be generated at the air duct air inlet 430, that is, suction can be generated at the air duct air inlet 430. This part of the suction can suck the air flow from the outdoor heat exchanger 300 and the electric control box 610 into the air duct piece 400 and discharge it outdoors, that is, the utility model can utilize the negative pressure generated at the air duct air inlet 430 to generate forced convection in the electric control box 610, so that more air can flow into the electric control box 610 from the heat dissipation inlet 613, and then flow to the air duct air inlet 430 from the heat dissipation outlet 612. The air flow rate flowing through the inside of the electric control box 610 can be larger, and then the heat of the electric control board 620 can be taken away by the flowing air flow, the temperature of the electric control component 600 can be prevented from being too high, and the heat dissipation effect of the electric control component 600 is better.

[0103] Moreover, in the utility model, the heat dissipation outlet 612 can be directly in communication with the air duct air inlet 430, the heat dissipation outlet 612 will not be blocked by other components, so that the suction generated at the air duct air inlet 430 can be more effectively utilized to generate forced convection in the electric control box 610, further improving the air flow rate of the electric control box 610, and the heat dissipation effect of the electric control component 600 by the flowing air flow is better.

[0104] In addition, in this way, the heat of the electric control component 600 can be taken away by the flowing air flow, the heat dissipation effect of the electric control component 600 is better, so that too many heat dissipation holes do not need to be arranged on the electric control box 610, not only facilitating the processing of the electric control box 610, but also improving the sealing property, fireproof property and rainproof property of the electric control box 610, and even if the electric control component 600 catches fire, the probability of fire spreading can be effectively reduced.

[0105] Therefore, the mobile air conditioner 1 according to the utility model embodiment can generate negative pressure at the air duct air inlet 430, and the negative pressure at the air duct air inlet 430 can be utilized to accelerate the air flow rate in the electric control box 610, and then forced convection can be formed in the electric control box 610, so that the electric control component 600 can be cooled by the air flow, and the heat dissipation effect of the electric control component 600 is improved.

[0106] Other configurations and operations of the mobile air conditioner according to the embodiments of the present application are known to those of ordinary skill in the art, and thus will not be described in detail.

[0107] The mobile air conditioner 1 in the present application performs a refrigeration cycle of the mobile air conditioner 1 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 adjusted and heat-exchanged.

[0108] 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.

[0109] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state 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 heat-exchanging with a material to be cooled using latent heat of evaporation of the refrigerant. Throughout the cycle, the mobile air conditioner 1 can adjust the temperature and humidity of the indoor space.
