Abstract
Description
Technical Field
[0001] This invention relates to the field of cooling equipment technology, specifically a portable air conditioner. Background Technology
[0002] In the hot summer, air conditioning can be installed in offices or sealed workshops to cool them down. However, for some large workshops with overhead cranes, the environment is not suitable for air conditioning installation. Generally, large fans can only be used to blow air, which is not ideal for cooling. At present, some companies have designed handheld portable air conditioners that can be placed on the ground or workbench and blow cool air directly at the operator. However, they have the defects of traditional air conditioners. Due to the presence of compressors and other components inside, they cannot be tilted during use and can only blow air in a fixed direction. They are also inconvenient to move, and it is necessary to ensure that they do not tilt, which has significant limitations. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention provides a portable air conditioner that can be angled to meet different airflow direction requirements without affecting the internal compressor.
[0004] The technical solution is as follows: a portable air conditioner includes an air conditioner casing, characterized in that a rotatable condenser box is installed inside the air conditioner casing, a compressor and a condenser are provided inside the condenser box, an evaporator and an exhaust fan are installed at the air outlet of the air conditioner casing, and the evaporator is connected to the compressor and the condenser through an air conditioner hose that passes through the condenser box.
[0005] A further feature is that the condenser box is composed of the outer shell of the condenser, a front baffle and two side baffles, and the two side baffles are rotatably connected to the two side walls of the air conditioner shell through a rotating shaft and bearings. A condenser fan is installed on one of the side baffles of the condenser box, and side air vents are opened on both the side baffle and the side wall of the air conditioner casing on that side. A compressor base plate is installed inside the condenser box, and the compressor is fixedly installed on the compressor base plate; The front baffle of the condenser box is provided with a first through groove corresponding to the air conditioning hose. The first through groove extends along the rotation direction of the condenser box, and a first shielding brush is provided in the first through groove. A water collection plate is provided below the evaporator, and a swingable hanging basket water box is provided next to the water collection plate. The water outlet of the water collection plate extends into the hanging basket water box. A water pump is provided in the hanging basket water box. The water pump is connected to the water tank in the condenser box through a return water hose that passes through the front baffle of the condenser box. An ultrasonic atomizer is provided in the water tank. The front baffle of the condenser box is provided with a second through groove corresponding to the return water hose. The second through groove extends along the rotation direction of the condenser box, and a second shielding brush is provided in the second through groove. Both the first and second shielding brushes are provided with upper and lower layers; The air conditioner casing is equipped with a negative ion dust reduction module. A gap channel is left between the condenser box and the inner wall of the air conditioner casing. On the side near the evaporator, the top and bottom of the inner wall of the air conditioner casing are respectively equipped with an upper baffle and a lower baffle that abut against the outer wall of the condenser box.
[0006] By adopting this invention, components such as the compressor are integrated into a refrigeration box. The condenser box and the outer shell are not fixed structures, but are connected in a way that allows them to rotate. When the outer shell is tilted, the condenser box can always be kept in a horizontal state, which will not damage the internal compressor. The air outlet on the outer shell can be adjusted to adjust the air outlet direction at will according to the angle of the outer shell. During the movement, the back and forth shaking of the outer shell will not affect the compressor, thus improving the practicality of the product. Attached Figure Description

Detailed Implementation
[0008] See Figures 1 to 5 As shown, a portable air conditioner includes an air conditioner housing 1, inside which a rotatable condenser box 2 is installed. The condenser box 2 contains a compressor 8 and a condenser 9. The condenser box 2 is composed of a condenser 9 housing 9-1, a front baffle 2-1, and two side baffles 2-2. The two side baffles 2-2 are rotatably connected to the two side walls of the air conditioner housing 1 via a rotating shaft 24 and bearings 25. A compressor base plate 2-3 is installed inside the condenser box 2, and the compressor 8 is fixedly installed on the compressor base plate 2-3. The state shown in the figure is the natural state, with the center of gravity located directly below the rotation center of the condenser box 2, ensuring that the compressor 8 is in a vertical position. Without external force, the condenser box 2 will not rotate.
[0009] An evaporator 6 and a fan 7 are installed at the air outlet 5 of the air conditioner casing 1. The air inlet 4 of the air conditioner casing 1 is located at the top of the air conditioner casing 1. The evaporator 6 is connected to the compressor 8 and the condenser 9 through an air conditioning hose 10 that passes through the front baffle 2-1 of the condenser box 2. 24 in the figure is an expansion valve, which works in conjunction with the evaporator 6, compressor 8, and condenser 9 to achieve the air conditioning cooling effect. It is generally fixed to the air conditioner casing 1 together with the evaporator 6.
[0010] A condenser fan 18 is installed on one of the side baffles of the condenser box 2, and both the side baffle and the side wall of the air conditioner casing 1 on that side are provided with side air vents 19. During the cooling process, the condenser fan 18 exhausts the heat generated by the condenser 9 through the side air vents 19.
[0011] A water collection plate 17 is provided below the evaporator 6, and a swingable hanging basket water box 12 is provided next to the water collection plate 17. The water outlet of the water collection plate 17 extends into the hanging basket water box 12. A flared channel 13 is provided between the evaporator 6 and the air outlet fan 7. The flared channel 13 is fixed to the air conditioner housing 1. The hanging basket water box 12 is connected to the outer wall of the flared channel 13 by a pin. When the air conditioner housing 1 is tilted, the hanging basket water box 12, like the condenser box 2, can remain in place, so that the condensate will not pour out. A water pump 14 is provided in the hanging basket water box 12. The water pump 14 is connected to the water tank 16 in the condenser box 2 through a return water hose 15 that passes through the condenser box 2. An ultrasonic atomizer is provided in the water tank 16. The condensate in the hanging basket water box 12 can be recycled into the water tank 16 and then atomized by the ultrasonic atomizer to cool the inside of the condenser box 2.
[0012] To ensure smooth relative rotation between the condenser box 2 and the air conditioner casing 1, i.e., to prevent the air conditioning hose 10 and return water hose 15 from affecting the condenser box 2 when moving with the air conditioner casing 1, a first through groove 2-4 corresponding to the air conditioning hose 10 and a second through groove 2-5 corresponding to the return water hose 15 are provided on the front baffle 2-1 of the condenser box 2. A first shielding brush 11 and a second shielding brush are installed in the first through groove 2-4 and the second through groove 2-5, respectively. The first shielding brush 11 and the second shielding brush have identical structures. Figure 7 Only the structure of the first shielding brush is shown. The first shielding brush 11 is mounted on the brush mounting plate 11-1, which is connected to the front baffle 2-1 by screws. In order to better block the airflow, both the first shielding brush 11 and the second shielding brush are provided with two layers, upper and lower, arranged staggered left and right.
[0013] A gap channel is left between the condenser box 2 and the inner wall of the air conditioner casing 1. A corresponding heat dissipation grille 22 is opened on the air conditioner casing 1, near the evaporator 6. The top and bottom of the inner wall of the air conditioner casing 1 are respectively equipped with an upper baffle 20 and a lower baffle 21 that abut against the outer wall of the condenser box 2. The upper baffle 20 and the lower baffle 21 are both installed by hinges 23 with torsion springs. Under the action of the torsion springs, they can be tightly attached to the outer wall of the condenser box 2 to achieve isolation. When the air conditioner casing 1 is rotated, the positions of the upper baffle 20 and the lower baffle 21 also change, but they are always tightly attached to the condenser box 2.
[0014] The outer wall of the air conditioner casing 1 is provided with a horizontal contact surface 1-1, an inclined contact surface 1-2, and a vertical direct contact surface 1-3. When the horizontal contact surface 1-1 is in contact with the table or the ground, the air is discharged horizontally. When the inclined contact surface 1-2 is in contact with the table or the ground, the air outlet is tilted upwards to achieve oblique air discharge. When the vertical direct contact surface 1-3 is in contact with the table or the ground, the air outlet is vertically upwards to achieve vertical air discharge. The air outlet can be adjusted according to the placement of the air conditioner casing 1. The tilt angle of the inclined contact surface 1-2 can be adjusted according to the actual situation, and multiple inclined contact surfaces 1-2 can be designed if conditions permit.
[0015] In addition to cooling, the device of this invention can also reduce dust. It is equipped with a negative ion dust reduction module, which includes an air concentration sensor, a negative ion generator, and a control module. The air concentration sensor is generally installed at the air outlet, which can be located below the evaporator 6, to detect the air quality at the air outlet. The control module controls the negative ion generator to generate negative ions based on the detected parameters, so that when the cold air coming out of the air outlet comes into contact with the dust, the dust becomes charged, thus achieving the effect of dust reduction.
