Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a portable air conditioning device. Background Technology

[0002] During operation, portable air conditioners cool and dehumidify the indoor air. Moisture in the air condenses on the low-temperature evaporator coils, forming condensate that collects in a drip tray or tank at the bottom. This condensate buildup requires users to manually empty it periodically, which is inconvenient. Furthermore, if the drip tray becomes too full, the safety switch will shut down the device, interrupting cooling. To improve the user experience, traditional portable air conditioners now allow the condensate to evaporate, eliminating the need for regular manual emptying.

[0003] In existing portable air conditioning equipment, the condensate evaporation method has low evaporation efficiency, the condensate cannot be completely treated, and the reliability of operation is low under high ambient humidity. Utility Model Content

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] In one embodiment, such as Figure 1As shown, a portable air conditioning device is provided, including an air conditioning body, a collection container 20, an atomizer 30, and a control module 40. The air conditioning body includes a housing 110 and a refrigeration component 120, which is disposed inside the housing 110. The collection container 20 is disposed below the refrigeration component 120 and is used to collect condensate generated by the refrigeration component 120. The atomizer 30 is disposed in the collection container 20, and the mist outlet of the atomizer 30 is disposed corresponding to the condensation inlet side of the refrigeration component 120. The control module 40 is disposed in the housing 110 and is connected to both the atomizer 30 and the refrigeration component 120. The control module 40 is configured to control the atomizer 30 to operate, so that the atomizer 30 atomizes the condensate in the collection container 20 and transmits the atomized water mist to the condensation inlet side of the refrigeration component 120.

[0035] The portable air conditioner can be a compressor-type portable air conditioner, which can be installed indoors or outdoors. The air conditioner body has a housing 110, which can be square or cylindrical in shape; alternatively, the housing 110 can be described as a modular shape. A moving component, such as four casters, is located below the housing 110. The housing 110 is based on a receiving cavity, which can be divided into a first receiving area and a second receiving area. The first receiving area is located above the second receiving area. The first receiving area is used to house the cooling component 120, and the second receiving area is used to collect and house the contents. The control module 40 can be located in either the first or second receiving area.

[0036] The refrigeration component 120 can be a compressor-type refrigeration component 120. The refrigeration component 120 is used to cool the input air and output the cooled airflow, thereby reducing the temperature of the local environment where the air outlet of the portable air conditioner is located. During operation, if the humidity of the input air reaches a preset value, the refrigeration component 120 will produce condensate. The collection container 20 can be a container made of plastic or metal, such as a shallow dish molded from a durable polymer. The collection container 20 is used to collect the condensate produced by the refrigeration component 120. The collection container 20 can be square or cylindrical in shape, and has an opening facing the condensate discharge end of the refrigeration component 120. Therefore, when the refrigeration component 120 produces condensate, the condensate can be collected in the collection container 20 through the opening.

[0037] The atomizer 30 can be installed on the side wall of the collecting container 20. The input end of the atomizer 30 is close to the bottom of the collecting container 20, and the output end of the atomizer 30 is close to the condensation inlet side of the cooling component 120. When the atomizer 30 is activated, it can atomize the condensate in the collecting container 20 and discharge the atomized water mist to the condensation inlet side of the cooling component 120, thereby achieving atomization and evaporation of the condensate and avoiding excessive condensate in the collecting container 20 that would require manual drainage by the user.

[0038] Since the control module 40 is electrically connected to the refrigeration component 120, the control module 40 can control the refrigeration component 120 to start working, enabling the refrigeration component 120 to regulate the air cooling. Since the control module 40 is connected to the atomizer 30, the control module 40 can control the atomizer 30 to work, thereby atomizing the condensate in the collection container 20 and outputting the atomized water mist to the condenser intake side of the refrigeration component 120. This water mist is transported with the condenser intake airflow of the refrigeration component 120, achieving efficient discharge of the collected condensate into the exhaust airflow of the refrigeration component 120 and pre-cooling the air entering the condenser, thereby improving the thermodynamic efficiency of the air conditioner.

[0039] In the above embodiments, the air conditioner body includes a housing 110 and a refrigeration component 120, which is disposed inside the housing 110. A collection container 20 is disposed below the refrigeration component 120 and is used to collect the condensate generated by the refrigeration component 120. An atomizer 30 is disposed in the collection container 20, with the mist outlet of the atomizer 30 corresponding to the condensation inlet side of the refrigeration component 120. A control module 40 is disposed in the housing 110 and is connected to both the atomizer 30 and the refrigeration component 120. The control module 40 is configured to control the atomizer 30 to operate, so that the atomizer 30 atomizes the condensate in the collection container 20 and transmits the atomized water mist to the condensation inlet side of the refrigeration component 120, thereby achieving efficient evaporation of the condensate generated by the portable air conditioner. This application collects the condensate generated by the refrigeration component 120 through the collection container 20, and controls the atomizer 30 through the control module 40 to atomize the condensate in the collection container 20, and discharges the generated water mist to the condensation air intake side of the refrigeration component 120, so as to introduce the water mist into the airflow of the condenser, thereby realizing the evaporation of the condensate, improving the evaporation efficiency of the condensate, and enhancing the reliability of the mobile air conditioning equipment under high ambient humidity.

[0040] In one embodiment, such as Figure 2 As shown, the control module 40 includes a water level sensor 410 and a controller 420; the water level sensor 410 is installed in the collecting container 20, and the controller 420 is connected to the water level sensor 410 and the atomizer 30 respectively.

[0041] The water level sensor 410 is installed inside the collection container 20. The water level sensor 410 is used to detect whether the water level in the collection container 20 has reached a preset water level threshold. For example, when the water level sensor 410 detects that the water level in the collection container 20 has reached the preset water level threshold, it sends a detection signal to the controller 420. The controller 420 triggers the atomizer 30 to start working based on the detection signal. The atomizer 30 then atomizes the condensate in the collection container 20 and outputs the atomized water mist to the condensation inlet side of the refrigeration component 120. This achieves efficient discharge of the collected condensate into the exhaust gas flow of the refrigeration component 120, preventing excessive condensate from overflowing from the collection container 20, and eliminating the need for manual drainage of the condensate by the user.

[0042] In one example, the water level sensor 410 is a non-contact water level sensor 410 or a solid-state water level sensor 410. For example, the water level sensor 410 is an optical level switch. When the optical level switch detects that the condensate level in the collecting container 20 is too high, it transmits a corresponding detection signal to the controller 420. The controller 420 then triggers the atomizer 30 to start working, thus accurately detecting the condensate level in the collecting container 20 and promptly triggering the atomizer 30 to atomize the condensate.

[0043] In one embodiment, such as Figure 2 As shown, a mounting port is provided on one side of the housing 110; the control module 40 also includes a touch display 430, which is located in the mounting port and connected to the controller 420.

[0044] The mounting port can be located on the top or front surface of the housing 110. The shape of the mounting port matches the shape of the touch display 430. For example, if the touch display 430 is square, then the mounting port is also square. The touch display 430 can be mounted in the mounting port of the housing 110 by means of snap-fit ​​or screw connection.

[0045] The controller 420 is connected to the touch display 430. The controller 420 can control the touch display 430 to display the water level status of the collecting container 20 (such as low water level, high water level, etc.) and the working status of the atomizer 30 (such as sleep mode, atomization mode, etc.). The touch display 430 can also be used to display the user interface, allowing users to select the corresponding operating mode by touch operation. It should be noted that the operating modes of the portable air conditioning device can include air conditioning fan operation mode, evaporative cooling mode, and adaptive control mode as follows: When the user selects evaporative cooling mode, the portable air conditioning device operates normally, and the controller 420 continuously monitors the water level sensor 410; when the user selects air conditioning fan operation mode, the controller 420 disables the compressor of the refrigeration component 120 and runs the fan of the refrigeration component 120. If the water level sensor 410 detects that the condensate in the collection container 20 reaches the preset water level threshold, the controller 420 activates the atomizer 30 to introduce mist into the indoor airflow, thereby providing a comfortable and low-energy-consumption evaporative cooling effect; when the user selects adaptive control mode, the controller 420 can automatically switch between evaporative cooling mode and air conditioning fan operation mode according to the ambient humidity and the condensate level in the collection container 20.

[0046] In one embodiment, the refrigeration assembly 120 includes a compressor, a condenser, an expansion valve, and an evaporator, which are respectively disposed within the housing 110; the compressor, condenser, expansion valve, and evaporator are connected in sequence; the compressor and expansion valve are respectively connected to the control module 40; the collecting container 20 is disposed below the evaporator; and the mist outlet end of the atomizer 30 is disposed corresponding to the condenser inlet side of the condenser.

[0047] The system consists of a compressor, condenser, expansion valve, and evaporator connected in sequence, with the compressor linked to the evaporator to form a refrigeration cycle. The compressor compresses the low-temperature, low-pressure refrigerant gas from the evaporator into a high-temperature, high-pressure gas, providing power for the refrigeration cycle. By compressing and transporting refrigerant vapor, it ensures the refrigerant circulates within the refrigeration cycle. The condenser cools and condenses the high-temperature, high-pressure refrigerant gas discharged from the compressor into a liquid, releasing heat. The expansion valve depressurizes the high-pressure refrigerant liquid to a low-temperature, low-pressure liquid state before it enters the evaporator. The evaporator absorbs heat at low temperatures, causing the refrigerant to evaporate into a gaseous state, thus lowering the temperature of the object being cooled.

[0048] The opening of the collecting container 20 faces the direction of condensate dripping from the evaporator, and the collecting container 20 is used to collect the condensate produced by the evaporator. The condenser inlet side refers to the airflow path into the condenser. The control module 40 is connected to the compressor and expansion valve, and the control module 40 controls the compressor and expansion valve to start working, allowing the evaporator to cool and regulate the incoming air. The condensate generated on the evaporator surface drips into the collecting container 20. When the water level in the collecting container 20 reaches a preset water level threshold, the control module 40 triggers the atomizer 30 to work. The atomizer 30 then atomizes the condensate in the collecting container 20 and outputs the atomized water mist to the condenser inlet side of the condenser. This water mist is transported with the condenser inlet airflow of the refrigeration component 120, achieving efficient discharge of the collected condensate into the exhaust airflow of the refrigeration component 120 and pre-cooling the air entering the condenser, thereby improving the thermodynamic efficiency of the air conditioner, increasing the condensate evaporation efficiency, and enhancing the operational reliability of the portable air conditioning equipment.

[0049] In one embodiment, such as Figure 2 As shown, an airflow channel is provided on the condenser air intake side, and a grid structure 132 is provided on the airflow channel. The mist outlet end of the atomizer 30 is connected to the grid structure 132.

[0050] The airflow channel is used to discharge exhaust gas. A grid structure 132 is provided on the side of the airflow channel facing the mist outlet end of the atomizer 30. The grid structure 132 has multiple spaced through holes. When the atomizer 30 starts atomizing, the water mist generated by atomization can enter the airflow channel through the through holes, effectively discharging the water mist into the airflow of the condenser. This achieves efficient evaporation of the condensate. Furthermore, the efficient evaporative pre-cooling of the condenser intake significantly reduces the condensation temperature and pressure of the refrigerant, alleviating the workload of the compressor and thus greatly improving the coefficient of performance (COP) of the equipment, and correspondingly reducing energy consumption.

[0051] In one embodiment, such as Figure 2 As shown, the control module 40 also includes an ambient humidity sensor 440 and an ambient temperature sensor 450; the ambient humidity sensor 440 and the ambient temperature sensor 450 are respectively connected to the controller 420.

[0052] Among them, the ambient humidity sensor 440 is used to detect the humidity of the environment in which the portable air conditioner is located; the ambient temperature sensor 450 is used to detect the temperature of the environment in which the portable air conditioner is located.

[0053] For example, an ambient humidity sensor 440 and an ambient temperature sensor 450 can be installed on one side of the housing 110. The controller 420 is connected to the ambient humidity sensor 440 and the ambient temperature sensor 450 respectively. The controller 420 can control whether the atomizer 30 is activated based on the ambient humidity detected by the humidity sensor 440 and the ambient temperature detected by the temperature sensor 450. If the ambient humidity is lower than a set point, the controller 420 triggers the atomizer 30. The water mist pre-cools the condenser air, thereby improving the energy efficiency of the equipment. If the ambient humidity is higher than the set point, the controller 420 will keep the atomizer 30 closed to avoid introducing more moisture into the already saturated airflow, thus preventing equipment malfunction. This allows for adjustment or disabling of the atomizer 30 under high humidity conditions (when the exhaust gas cannot absorb more moisture), preventing oversaturation of the air and improving the reliability of the portable air conditioning equipment.

[0054] In one embodiment, the controller 420 is located above the collection container 20, and an isolator is provided between the controller 420 and the collection container 20.

[0055] The isolator can be plate-shaped and can be installed at the opening of the collection container 20 by snap-fit ​​or screw-fit. Since the isolator is installed between the controller 420 and the collection container 20, it can prevent the condensate dripping into the collection container 20 from splashing and avoid the controller 420 from coming into contact with the condensate, which could lead to circuit failure.

[0056] In one embodiment, such as Figure 1 As shown, the portable air conditioning unit also includes an alarm 50, which is mounted on the housing 110 and connected to the control module 40.

[0057] The alarm 50 may be a buzzer and / or an LED flashing light.

[0058] Based on the connection of the control module 40 to the alarm 50, when the control module 40 detects a system abnormality, the alarm 50 is triggered to issue an alarm, reminding the user to check the abnormal situation in time.

[0059] In one embodiment, the atomizer 30 is an ultrasonic atomizer 30.

[0060] The ultrasonic atomizer 30 can be set to a frequency greater than 100kHz. The power consumption of the ultrasonic atomizer 30 can be less than 10W, and the median particle size of the water mist produced by the ultrasonic atomizer 30 is less than 100 micrometers.

[0061] The ultrasonic atomizer 30 includes an ultrasonic atomizing transducer composed of a piezoelectric ceramic plate. When a voltage is applied to the ultrasonic atomizing transducer, the piezoelectric ceramic plate vibrates at a high frequency, and this vibration is transmitted to a metal diaphragm with micropores. In a preferred embodiment, the ultrasonic atomizing transducer operates in the range of 100-500 kHz. For example, an operating frequency of 112 kHz can produce extremely fine mist with a median particle size of approximately 50-60 micrometers, and its evaporation efficiency is far higher than that of large water droplets produced by conventional mechanical systems.

[0062] The atomizer 30 has extremely low power consumption, typically around 2W, and its operation has a negligible impact on the overall energy consumption of the device. The atomizer 30 does not require significant feed pressure and generates low-velocity aerosols, facilitating the entrainment of water mist into the condenser's airflow without causing overspray or requiring a complex demister, thus achieving efficient evaporation of condensate.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
