It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

The market for air conditioners has been expanding year by year, and recently, mobile air conditioners for single person space have been developed. The mobile air conditioner has the feature that key components constituting the refrigeration system, such as a condenser and an evaporator, are all mounted on the same housing. In such a mobile air conditioner, a part of the product can be made to do without treating dew generated by an evaporator. The drainless technology can be roughly classified into two types, one is a technology of adjusting the evaporation temperature so that condensation is not generated in sensible heat exchange; another technique is to dehumidify the evaporator in advance by using a desiccant or the like, and to exchange only sensible heat in the evaporator. Both of these techniques limit the necessary evaporation capacity of the sensible heat exchanger and therefore the use is often limited. However, in the heating operation, the condenser and the evaporator are replaced, and the heat removal technology cannot be used at this time, so that the heating capacity can only be limited in the heating process, and the evaporator is prevented from generating condensation. Therefore, the drainless mobile air conditioner is generally a single chiller, or generally has only a function of assisting heating.

Referring to fig. 1 to 5, the present embodiment provides a mobile air conditioner 100, and the mobile air conditioner 100 according to the embodiment of the present invention can solve the above-mentioned problems, and will be described in detail.

Referring to fig. 1, the mobile air conditioner 100 includes: a housing 110, a vaporizing heat exchanger 120, a water tank 130, and an exhaust blower 140; the vaporizing heat exchanger 120, the water tank 130 and the exhaust fan 140 are all disposed in the housing 110, and the water tank 130 is located between the vaporizing heat exchanger 120 and the exhaust fan 140.

In the above technical scheme, the water tank 130 is used for collecting the condensation water generated during working, the exhaust fan 140 is used for sucking air flow, so that the air flow is heated by the vaporization heat exchanger 120, and then passes through the water tank 130, so that the condensation water is vaporized and evaporated, and then the gas obtained after the vaporization of the condensation water is discharged by the exhaust fan 140, so that the technical effect of no drainage is achieved.

Referring to fig. 1, the mobile air conditioner 100 further includes an exhaust heat exchanger 150, an exhaust chamber 112 is formed inside the housing 110, and the exhaust heat exchanger 150, the vaporization heat exchanger 120, the water tank 130, and the exhaust fan 140 are all disposed in the exhaust chamber 112.

In the above technical solution, by providing the exhaust chamber 112, the gas generated after the heat exchange between the exhaust heat exchanger 150 and the vaporization heat exchanger 120 is conveniently and simultaneously exhausted.

It should be noted that the exhaust heat exchanger 150 may be disposed on the upper side of the water tank 130, and a water receiving tray (not shown) is installed below the exhaust heat exchanger 150, and is used for collecting condensed water generated during operation of the exhaust heat exchanger 150 and conveying the condensed water into the water tank 130 through a conveying pipeline (not shown). Because the water tank 130 is positioned at the lower side of the exhaust heat exchanger 150, the condensed water can flow to the water tank 130 by itself under the action of gravity, so that a power element is not required to drive the condensed water to move, thereby helping to reduce the energy consumption of the mobile air conditioner 100.

In addition, the housing 110 includes an air intake side (not shown), an air outlet side (not shown), and an air exhaust side (not shown), where the air outlet side and the air exhaust side are disposed opposite to each other, and the air intake side is two, and both air intake sides are disposed between the air outlet side and the air exhaust side.

Of course, in other embodiments of the present invention, the exhaust gas heat exchanger 150 and the vaporization heat exchanger 120 may be an integrated heat exchange coil structure (not shown), where the upper portion of the integrated heat exchange coil is the exhaust gas heat exchanger 150 and the lower portion is the vaporization heat exchanger 120.

Referring to fig. 1, an air outlet chamber 114 is further formed inside the housing 110, and the air outlet chamber 114 is spaced apart from the air discharge chamber 112.

In the above technical solution, the air outlet cavity 114 is provided to guide out the corresponding cold air flow or warm air flow during cooling or heating.

It should be noted that, by separating the air outlet chamber 114 from the air exhaust chamber, the air flows with different temperatures flowing out can be prevented from being mixed, so as to ensure the cooling or heating effect of the mobile air conditioner 100.

Referring to fig. 1, the mobile air conditioner 100 further includes an air-out heat exchanger 170 and an air-out fan 180, and the air-out heat exchanger 170 and the air-out fan 180 are disposed in the air-out cavity 114.

In the above technical solution, the air outlet fan 180 is configured to suck the air flow, so that the air flow exchanges heat through the air outlet heat exchanger 170, and then the air flow after heat exchange is led out.

Referring to fig. 1, the mobile air conditioner 100 further includes a filter screen 194, and the filter screen 194 is disposed at a side of the vaporizing heat exchanger 120 remote from the water tank 130.

In the above technical solution, the filter screen 194 is provided to filter the airflow passing through the vaporization heat exchanger 120.

It is noted that, on the side of the air-out heat exchanger 170 away from the air-out fan 180 and the side of the exhaust heat exchanger 150 away from the air-out fan, a filter screen 194 is also provided, so as to filter all the air flows entering the inner cavity of the housing 110, avoid mixing excessive impurities, avoid damaging each fan, and prevent reducing the heat exchange efficiency of each heat exchanger.

Referring to fig. 2, the exhaust chamber 112 includes a first cavity 1121 and a second cavity 1122 which are separately provided, the exhaust blower 140 includes a first exhaust blower 141 and a second exhaust blower 142, the exhaust heat exchanger 150 and the first exhaust blower 141 are provided in the first cavity 1121, and the vaporizing heat exchanger 120, the water tank 130, and the second exhaust blower 142 are provided in the second cavity 1122.

In the above technical solution, by setting the first cavity 1121, the second cavity 1122, the first exhaust fan 141 and the second exhaust fan 142, the gas after heat exchange of the exhaust heat exchanger 150 and the vaporization heat exchanger 120 is not mixed in the exhaust process, so as to avoid re-forming condensation when the low-temperature gas after heat exchange of the exhaust heat exchanger 150 and the high-temperature gas after heat exchange of the vaporization heat exchanger 120 are gathered in the heating process.

When the mobile air conditioner 100 is in refrigeration operation, the external air flow is changed into low-temperature air after heat exchange by the exhaust heat exchanger 150, and the external air flow is changed into high-temperature air after heat exchange by the vaporization heat exchanger 120, so that new cold dew is easily generated after the two gases are mixed, and the two gases are prevented from contacting by separating the flow paths of the two gases, thereby preventing new dew from being formed in the gas discharging process.

Referring to fig. 3 and 4, the mobile air conditioner 100 further includes a compressor 190, the vaporizing heat exchanger 120, the air-out heat exchanger 170, and the exhaust heat exchanger 150 are sequentially communicated and form a closed circuit.

In the above technical solution, the compressors 190 and the heat exchangers are orderly arranged, so that the heat exchange medium circularly flows in the closed loop, and heat exchange operations under different conditions are further realized.

It should be noted that a four-way valve 196 is also provided in the closed circuit, and different connectors of the four-way valve 196 are connected to different components in different operation modes (cooling or heating). Further, an expansion valve 192 is provided between the exhaust heat exchanger 150 and the outlet heat exchanger 170, and the expansion valve 192 is provided to control the flow rate and pressure of the medium flowing therethrough.

During cooling operation, the flow path of the heat exchange medium in the mobile air conditioner 100 system is: compressor 190→vaporizing heat exchanger 120→air outlet heat exchanger 170→expansion valve 192→exhaust heat exchanger 150→compressor 190, wherein exhaust heat exchanger 150 acts as an evaporator in the process and air outlet heat exchanger 170 acts as a condenser in the process.

During heating operation, the flow path of the heat exchange medium in the mobile air conditioner 100 system is: compressor 190→vaporizing heat exchanger 120→exhaust heat exchanger 150→expansion valve 192→exhaust heat exchanger 170→compressor 190, wherein exhaust heat exchanger 150 acts as a condenser in the process and exhaust heat exchanger 170 acts as an evaporator in the process.

Referring to fig. 1 and 5, the mobile air conditioner 100 further includes an evaporation element 160, and the evaporation element 160 is disposed in the water tank 130.

In the above technical solution, by disposing the evaporation element 160 in the water tank 130, the evaporation element 160 is convenient to directly evaporate and evaporate the condensed water in the water tank 130, which is helpful for improving the evaporation efficiency of the condensed water.

It should be noted that the evaporation element 160 may be an electric heating element, a gas heating element, or a hydraulic heating element, and generates heat by self-heating, thereby evaporating and vaporizing the condensed water in the water tank 130.

Referring to fig. 5, a limiting plate 132 is connected to the inside of the water tank 130, a limiting cavity is formed between the limiting plate 132 and the side wall of the water tank 130, the evaporation element 160 is located in the limiting cavity, and ventilation holes 134 are formed in both the water tank 130 and the limiting plate 132.

In the above technical solution, the limiting plate 132 is used for limiting the evaporation element 160, so as to avoid the position of the evaporation element 160 in the water tank 130 from being easily changed, and facilitate the aggregation of the gas evaporated by the evaporation element 160, so as to avoid the too fast heat dissipation, and further improve the evaporation efficiency of the condensed water around the evaporation element 160.

By providing the ventilation holes 134, the heated air flow enters the water tank 130 to evaporate and vaporize the condensed water. And the ventilation holes 134 are disposed on two sides of the evaporation element 160, the evaporated gas of the evaporation element 160 is generally accumulated in the limiting cavity, and when the gas heated by the evaporation heat exchanger 120 flows through the ventilation holes 134, the gas flow in the limiting cavity can be carried out, so as to avoid long-time accumulation of the evaporated gas in the limiting cavity.

Referring to fig. 5, a vaporization gap 136 is formed between the stopper 132 and the top wall of the water tank 130.

In the above technical solution, by providing the vaporization notch 136, the heated air flow and the air flow formed after the condensate water is vaporized by evaporation can flow out of the water tank 130 through the vaporization notch 136.

In addition, a liquid level sensor 138 is connected to the inner side of the water tank 130, and the liquid level sensor 138 is used to detect the real-time water output in the water tank 130, and once the water storage amount exceeds a set value, the mobile air conditioner 100 stops running. After stopping the operation, the control for improving the evaporation temperature is performed, so that the generation of condensation is prevented; or continuously operate the exhaust fan 140.
