Description

Technical Field

[0001] This utility model relates to a portable air conditioner, and more particularly to an integrated heat-insulating air cavity for a portable air conditioner. Background Technology

[0002] Compared to traditional air conditioners, portable air conditioners have no outdoor unit, require no professional installation, and feature an integrated design where the compressor, evaporator, and condenser are all combined. They can be used simply by plugging them in, eliminating the need for professional relocation. They won't disrupt the overall aesthetics of the room, and they won't be limited to cooling only a specific area. Equipped with omnidirectional casters, they can be moved at will, thus facilitating user needs and increasing the flexibility of air conditioning equipment.

[0003] Because portable air conditioners integrate the condenser and evaporator into the same housing, the overall design and insulation of the air duct are subject to high requirements in order to improve thermal efficiency and, in particular, avoid energy loss. In existing technologies, the air duct is poorly designed, resulting in low air delivery efficiency. At the same time, the air duct is made of plastic or sheet metal, which has no insulation function. Therefore, insulation material needs to be applied to the plastic or sheet metal, which not only increases material and assembly costs but also increases the overall weight, affecting the portability of the portable air conditioner. In addition, it is easy to generate resonance and noise. Utility Model Content

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] See Figures 1-9 This utility model provides an integrated heat preservation air cavity for a portable air conditioner, which includes a shell 1, a first volute assembly 3, an evaporator 51, a second volute assembly 4, and a condenser 52.

[0033] The housing 1 serves as an installation and support carrier for mounting other components. The housing 1 is a vertically arranged cuboid structure. Rollers are provided at the bottom of the housing 1 to facilitate overall movement. The interior of the housing 1 is hollow, forming an installation cavity. A horizontal partition 2 is provided in the installation cavity, which divides the housing 1 into an upper cavity and a lower cavity. A first air inlet is provided on the side wall of the upper cavity, and a first air outlet is provided at the top of the upper cavity. A second air inlet and a second air outlet are provided on the side wall of the lower cavity, and the second air inlet and the first air inlet are located on different side walls of the housing 1.

[0034] The first volute assembly 3 is installed in the upper cavity and is located between the first air inlet and the first air outlet, thus forming a first air duct. A first impeller 34 is provided in the first air duct. The first impeller 34, by rotating, can generate airflow within the first air duct, i.e., produce wind. The evaporator 51 is located on the first air inlet and is used to cool the passing airflow, thereby generating cold air. In this application, the first volute assembly is made of thermal insulation material, which is foamed plastic. Foamed plastic is a type of polymer material formed by dispersing a large number of gas micropores in solid plastic. It has characteristics such as light weight, heat insulation, sound absorption, and shock absorption, meeting the design concepts of heat insulation, noise reduction, and weight reduction in this application, reducing energy consumption, reducing operating noise (wind noise), and reducing overall weight. In this embodiment, the foamed plastic is expanded polystyrene, i.e., EPS, which is similar to... It has waterproof and moisture-proof functions, preventing condensation and mold growth. In this application, the expanded polystyrene has a density of 35-45 kg / m³, high hardness, and can achieve good connection and support, thereby improving the overall structural strength. By using foamed plastic to make the volute, the production cost is reduced. The mold can be made of aluminum mold, which has low mold opening cost and can be recycled, greatly reducing the production cost. At the same time, unlike the plastic plates or sheet metal in the prior art, there are no assembly gaps and impact noise during vibration, which greatly reduces the working noise and improves the user experience. In addition, after using the above materials, the thickness of the volute can be appropriately increased to further improve its structural strength. At the same time, it can effectively reduce the working noise, has heat insulation and sound insulation functions, and is lightweight and easy to assemble.

[0035] In this application, a bracket plate 32 is fixedly installed in the upper cavity by screws. The bracket plate 32 is a metal plate or a plastic plate and is used to install and fix the first volute assembly. The bracket plate 32 is generally rectangular, with its edges bent at 90 degrees to the same side to form a mounting part 321 for fixed connection with the inner wall of the housing and the horizontal partition 2. The first volute assembly 3 is fixed on the bracket plate 32. At the same time, a first drive motor 31 is fixed on the bracket plate 32. A hole 320 is opened on the bracket plate 32 to allow the first drive motor to pass through or to allow the output shaft of the first drive motor to pass through. In order to improve the installation and connection strength and avoid the generation of lever arm, in this application, the first drive motor is a fan motor, and its installation position is located in the middle position of the motor. Therefore, no lever arm will be generated after connecting with the bracket plate 32, the installation is reliable and stable, and no torsional force will be generated on the bracket plate. The output shaft of the first drive motor 31 is connected to the first impeller 34, which is located inside the first volute assembly 3, thereby generating airflow.

[0036] The first volute assembly 3 in this application is made of foam plastic. To facilitate manufacturing and subsequent assembly, especially the installation of the first impeller, the first volute assembly 3 is formed by splicing a first volute 33 and a second volute 35. A volute cavity is formed between the first volute 33 and the second volute 35. An air inlet 350 is provided at the end of the volute cavity, serving as the air inlet and facing the first air inlet. An air outlet 350 is provided at the top of the volute cavity, serving as the air outlet and facing the first air outlet. To facilitate rapid positioning and assembly, a first positioning structure is provided between the first volute 33 and the second volute 35. This first positioning structure consists of a positioning groove and a positioning protrusion. For details, please refer to [link to relevant documentation]. Figures 6-8 The first volute 33 includes a first plate 33a and a first arc-shaped half-shell 33b disposed on the first plate 33a. A central hole 330 is provided on the first plate 33a, which can accommodate the drive motor or drive shaft of the first impeller. Several lugs are provided on the edge of the first plate 33a, and a first mounting hole 322 is provided on the lug for fixed connection with the support plate 32. The end face of the first arc-shaped half-shell 33b is flat, forming a first mounting surface. A first positioning groove 333 is provided on the outer side of the first mounting surface. There are multiple first positioning grooves 333, which are arranged sequentially along the contour direction of the first arc-shaped half-shell 33b. The first volute is integrally formed.

[0037] The second volute 35 includes a second plate 35a and a second arc-shaped half-shell 35b disposed on the second plate 35a. The second plate 35a is parallel to the first plate 33a. A hole is formed in the second plate 35a to form an air inlet 350. The end face of the second arc-shaped half-shell 35b is flat, forming a second mounting surface. The second mounting surface can fit with the first mounting surface to form a complete volute cavity. A first positioning protrusion 353 is provided on the outer side of the second mounting surface. The first positioning protrusion 353 corresponds to the first positioning groove 333 and can be interlocked to form a complete volute cavity structure. The first volute and the second volute can be fixedly connected by adhesive or tape.

[0038] The second plate 35a is rectangular, and its edges are bent outward, that is, bent at 90 degrees away from the direction of the volute, forming an air inlet 354. This air inlet 354 can be connected to the evaporator. Furthermore, the upper edge of the air inlet 354 extends towards the evaporator to form a shielding part, which covers the upper end of the evaporator, improving the air inlet and guiding effect, avoiding air leakage, improving the cooling effect, and effectively reducing wind noise. The above-mentioned second volute is integrally formed.

[0039] In this application, the first volute assembly 3 further includes an air outlet 36, the shape of which is the same as that of the air outlet hole. It is fitted onto the upper part of the first volute and aligned with the air outlet hole. Its upper end connects to the first air outlet hole on the top of the housing, guiding airflow to the first air outlet for discharge. This reduces or prevents air leakage, increases air outlet pressure, increases air outlet distance, and effectively reduces wind noise, resulting in good performance. The air outlet 36 is fitted onto the air outlet hole, and a second positioning structure is provided between its contact surfaces with the first and second volute housings. The positioning structure includes a second positioning groove I 3310 on the top of the first volute, a second positioning groove II 3510 on the top of the second volute, and a second positioning protrusion 361 at the bottom of the air outlet. The second positioning protrusion 361 corresponds to the second positioning groove I 3310 and the second positioning groove II 3510 and can be inserted into the second positioning groove I 3310 and the second positioning groove II 3510 to achieve positioning. In this application, the air outlet 36 is fixed to the top surface 331 of the first volute and the top surface 351 of the second volute by adhesive or tape.

[0040] The second volute assembly 4 is located in the lower cavity, between the second air inlet and the second air outlet, forming a second air duct. A second impeller is located in the second air duct, and a second drive motor is located in the lower cavity. The motor is connected to the second impeller and is used to drive the second impeller to rotate, thereby generating airflow in the second air duct. The condenser is located at the air inlet of the second air duct, i.e., at the second air inlet. The condenser is connected to the evaporator 51 through a pipeline and is used to release heat from the internal medium, i.e., to dissipate heat. Therefore, the air outlet of the second air duct is hot air.

[0041] This utility model features an integrated insulated air chamber for portable air conditioning. It employs an upper and lower air duct design, increasing the volute space, improving air intake and exhaust volume, extending air delivery distance, and enhancing performance. The volute is made of foam plastic, offering excellent shaping capabilities, low mold and manufacturing costs, and can be manufactured using aluminum molds.
