The mobile air conditioner is provided with universal wheels at the bottom of its shell, so that it can be moved within a certain range; the window air conditioner is an air conditioner that can be installed on the window; and the desktop air conditioner is usually placed on the desktop for personal use.

The following text will describe the mobile air conditioner in some embodiments with reference to the drawings in the specification. It should be noted that although the following description takes a mobile air conditioner as an example, it does not exclude the possibility that its technical solution is applied to all other types of integral air conditioners including window air conditioners or desktop air conditioners.

Figure 1 and Figure 2 are schematic diagrams of the exploded structure of the mobile air conditioner (without the air supply volute assembly located inside the housing). 1 and 2, the mobile air conditioner 10 includes a housing 100, an air supply volute assembly 200 (the air supply volute assembly 200 is not shown in Figures 1 and 2, please understand in conjunction with Figures 4 and 5), a row The wind volute assembly 300, the middle partition 400 and the electric control box assembly 500 (the electric control box assembly 500 is not shown in FIGS. 1 and 2, please understand in conjunction with FIGS. 4 and 5).

The housing 100 shown in FIGS. 1 and 2 includes a front housing 130 and a rear housing 140. The upper part of the front case 130 has a front panel structure. The front housing 130 and the rear housing 140 are assembled through screw holes or other connection methods to form a complete structure of the housing 100. It is understandable that the housing 100 may also be composed of a front housing, a side housing and a rear housing, or be processed by an integral molding process.

The air supply volute assembly 200, the exhaust volute assembly 300, the middle partition 400, and the electric control box assembly 500 are all located inside the housing 100, and the center partition 400 divides the space inside the housing 100 into upper and lower parts as a whole. Floor installation space. The air supply volute assembly 200 is provided in the upper installation space, and the exhaust volute assembly 300 is provided in the lower installation space. In other words, the air supply volute assembly 200 is located above the center partition 400 and the exhaust volute assembly 300 is located below the center partition 400.

Figures 1 to 5 all show the reference direction coordinate system of the embodiments of the present disclosure. With reference to the directions shown in the drawings, the air supply volute assembly 200 and the central partition 400 define an accommodation space in the front and rear direction, and the electrical control box assembly 500 is located in the accommodation space.

In the traditional mobile air conditioner, the electric control box assembly is usually placed on the side of the casing, so the width direction of the entire mobile air conditioner cannot be compact. In the above-mentioned embodiment, the air supply volute assembly and the exhaust volute assembly of the mobile air conditioner are arranged in two upper and lower layers, and the two are separated by a central partition. The air supply volute assembly defines an accommodation space with the middle partition in the front and rear direction, and the electric control box assembly is placed under the air supply volute assembly and the accommodation space above the center partition, reducing the body of the mobile air conditioner The width effectively utilizes the space at the lower part of the air supply volute assembly and improves the space utilization rate.

Fig. 3 is a schematic diagram of the external structure of the mobile air conditioner from a left perspective. In some embodiments, specifically, as shown in FIG. 3, the outer contour of the blower volute assembly 200 is inclined from top to bottom to the rear of the entire mobile air conditioner 10, so that the front end of the blower volute assembly 200 The accommodating space is formed below. The accommodating space is a space jointly defined by the middle partition 400, the blower volute assembly 200, and the casing. It is understandable that the accommodating space can also be arranged below the rear end of the air supply volute assembly, and the electric control box assembly can be arranged below the rear end of the air supply volute assembly; the formation of the accommodation space is not limited to the air supply volute assembly. The way in which the outer contour of the shell component is inclined to transition downward, and the accommodating space can be constructed through stepped or recessed structural design. It can be understood that those skilled in the art may also choose to construct a receiving space below the rear end of the blower volute assembly 200.

4 and 5 are schematic diagrams of the internal structure of the mobile air conditioner. 4 and 5, in some embodiments, the air supply volute assembly 200 includes an evaporator 220 and an air supply volute 240. The two ends of the evaporator 220 are bent relative to the middle part, and the shape of the evaporator 220 is The air supply volute 240 is compatible. If the evaporator 220 is cut along a vertical cross section perpendicular to the left and right direction, a strip-shaped cross-sectional structure in which the upper and lower ends are bent relative to the middle portion can be obtained.

The evaporator 220 adopts a structure design with two ends bent. Compared with the straight row evaporator structure design, the height of the evaporator is reduced, and the height of the mobile air conditioner is also reduced; it is the same as the straight row evaporator of the same height. In comparison, the structure design with the upper and lower ends bent, in fact, increases the surface area of the evaporator, that is, increases the heat exchange area of the evaporator. Furthermore, the evaporator 220 is shaped to match the air supply volute 240. , The overall structure of the mobile air conditioner is compact, and the space utilization rate inside the mobile air conditioner is improved.

Referring to FIGS. 6 and 7, in some embodiments, the air supply volute assembly 200 has a first air inlet air passage and a first air outlet air passage, and a first air inlet 600 is provided on the rear side of the housing 100. The top of the body is provided with a first air outlet 700, the first air inlet is communicated with the first air inlet duct, and the first air outlet 700 is communicated with the first air outlet duct. Specifically, the first air inlet is provided on the upper part of the rear side of the housing 100, corresponding to the area of the upper installation space where the air blowing volute assembly is located.

The air enters the first air inlet duct of the air supply volute assembly from the rear side of the fuselage, and then flows out from the top of the fuselage through the first air outlet air duct. The air flow direction of the blower volute assembly can be summarized as the air entering at the rear side of the housing and the air exiting at the upper part of the housing. It can be understood that the first air inlet duct is connected to the first air outlet duct. In the traditional mobile air conditioner, air is supplied from the front side (usually the front panel) of the housing, that is, cool air is output from the front side of the housing to the room. In this embodiment, the cool air is output from the upper part of the housing to the room. Compared with the traditional air supply structure design, the front part of the housing leaves a space to accommodate other components, such as electrical control box components. This structural design not only makes the air flow reasonable, but also makes the overall structure compact.

Please continue to refer to FIGS. 1, 2 and 4. In some embodiments, the mobile air conditioner 10 further includes an air guide plate 720, and the air guide plate 720 is rotatably disposed at the first air outlet 700. After the mobile air conditioner is turned on and running, the air deflector 720 rotates and no longer blocks the first air outlet 700, and cool air is output to the room from this; when the mobile air conditioner is no longer running, the air deflector 720 rotates to block the first air outlet again. With an air outlet 700, there is no more air flow to the room.

Referring to FIGS. 4 and 5, in some embodiments, the mobile air conditioner 10 further includes a compressor 340, and the exhaust volute assembly 300 includes a condenser 320 and an exhaust volute 360. The bottom of the housing 100 is provided with a chassis 120. The exhaust volute 360, the condenser 320 and the compressor 340 are all located between the chassis 120 and the middle partition 400, and the exhaust volute 360, the condenser 320 and the compressor 340 are located between the chassis 120 and the central partition 400. The shells are sequentially arranged in the left-right direction. The exhaust volute, the condenser and the compressor are arranged closely in the space between the chassis and the middle partition, which not only makes the internal components of the exhaust volute assembly tidy and orderly but also facilitates disassembly and assembly, and further makes the entire mobile air conditioner The structure is compact.

In some embodiments, the exhaust volute assembly 300 further includes an exhaust motor (not shown in the figure). Please refer to FIG. 4, the condenser 320 is placed perpendicular to the axis of the exhaust motor. The exhaust motor is used to generate driving air pressure and promote the circulation of air in the exhaust volute. If the condenser is placed obliquely to the exhaust motor shaft, it occupies some space in the width direction of the housing. The condenser is placed perpendicular to the shaft of the exhaust motor, which makes the structure more compact in the width direction of the housing (that is, the left and right directions shown in FIG. 1 and FIG. 2).

Referring to FIG. 1, in some embodiments, the exhaust volute assembly 300 has a second air inlet air passage and a second air outlet air passage, and the rear side of the housing 100 is provided with a second air inlet 800 and a second air outlet 900, the second air inlet 800 is communicated with the second air inlet duct, and the second air outlet 900 is communicated with the second air outlet duct. It is understandable that the second air inlet duct is connected to the second air outlet duct.

The air enters the second air inlet duct of the exhaust volute assembly from the rear side of the fuselage, and then flows out from the rear side of the fuselage again through the second air outlet air duct. The air flow direction of the exhaust volute assembly can be summarized as the wind in one place on the rear side of the casing and the wind out in the other place on the rear side of the casing. The opening position of the second air outlet is used to connect accessories such as an exhaust duct, and the air in the exhaust volute is discharged to the outside through the exhaust duct. The air inlets and air outlets related to the exhaust volute assembly are uniformly arranged on the rear side of the shell, which is neat and orderly and has a compact structure and is convenient to install related accessories. This structural design not only makes the air flow reasonable, but also makes the overall structure compact.

In some embodiments, the opening of the second air outlet duct is extended to the position where the second air outlet 900 is located. It should be noted that the second air outlet 900 is different from the opening of the second air outlet. The second air outlet 900 is opened in the housing 100 of the mobile air conditioner, and the opening of the second air outlet is the end of the second air outlet of the exhaust volute 360, and the exhaust volute 360 is installed on the housing 100's interior.

In the traditional mobile air conditioner, the opening position of the second air outlet is a certain distance away from the position of the second air outlet. From the flow direction of the discharged air, the air discharged from the exhaust volute has not yet reached the second air outlet, but has already flowed out of the opening of the second air outlet. The position where the second air outlet of the mobile air conditioner is located usually requires an exhaust duct to be installed so that the air inside the mobile air conditioner is discharged to the outside through the exhaust duct. However, the air discharged from the exhaust volute of the traditional mobile air conditioner has not yet reached the second air outlet, and has already flowed out of the opening of the second air outlet. A complicated sealing structure has to be used to ensure that the exhaust volute is discharged. The air will not flow into the room. In this embodiment, the opening of the second air outlet (equivalent to the air outlet of the exhaust volute) extends and extends into the second air outlet on the rear side of the casing, so that the opening of the second air outlet is in line with Exhaust ducts and other exhaust accessories are in direct contact, reducing the path length that may leak air, without additional sealing structure, and less air leakage at the second air outlet.

Please continue to refer to Figures 4 and 5, in some embodiments, the air supply volute assembly 200 includes an evaporator 220 and an air supply volute 240. Both the evaporator 220 and the air supply volute 240 are located above the central partition and evaporate. The fan 220 and the blower volute 240 are sequentially arranged in the front-rear direction of the housing 100. The evaporator and the air supply volute are arranged tightly in sequence on the middle partition, which not only makes the internal components of the air supply volute assembly tidy and orderly and facilitates disassembly and assembly, but also further makes the structure of the entire mobile air conditioner compact.

Although the embodiments of the present disclosure have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and modifications can be made to these embodiments without departing from the principle and purpose of the present disclosure. The scope of the present disclosure is defined by the claims and their equivalents.
