Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an integrated DC inverter household air conditioner without an outdoor unit. Background Technology

[0002] Air conditioners without outdoor units integrate the functions of a traditional outdoor unit (such as the compressor and condenser) into the indoor unit, eliminating the need for a separate outdoor unit. Currently, split-type air conditioners require separate installation of indoor and outdoor units, resulting in complex installation, long refrigerant piping, and high maintenance costs. While existing window air conditioners have a single, integrated structure, they generally suffer from drawbacks such as high noise levels, low heat dissipation efficiency, and bulky appearance.

[0003] In practical use, existing integrated DC inverter household air conditioners without outdoor units typically install condenser tubes inside the condenser. As the high-pressure gaseous refrigeration fluid flows along the condenser tubes, it combines with the fins installed inside the condenser to achieve a cooling effect. However, traditional condenser tubes are thick, which is not conducive to heat exchange. Moreover, the fins are distributed around the condenser tubes and usually adopt a non-contact installation structure, which makes it difficult for the condenser tubes to exchange heat with the external hot air quickly, significantly reducing the heat dissipation efficiency. Therefore, this application proposes an integrated DC inverter household air conditioner without outdoor units that can improve heat dissipation efficiency. Utility Model Content

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0016] like Figures 3-6 As shown, this utility model proposes an integrated DC inverter household air conditioner without an outdoor unit, including a housing 1. A compressor 7 and an evaporator 8 are fixedly installed inside the housing 1, connected as a single unit via conduits. An inclined condenser 6 is also fixedly installed inside the housing 1. This inclined installation allows for a larger condenser 6 to be installed within the limited space inside the housing 1, increasing the overall heat exchange area of ​​the condenser 6, compared to a flat installation. The condenser 6 is fixedly connected to the compressor 7 and evaporator 8 via two sets of conduits, respectively. The compressor 7 then delivers high-pressure... Gaseous refrigerant is pressed into the condenser tube 61 inside the condenser 6 to facilitate heat exchange with the indoor hot air. When liquid refrigerant enters the evaporator 8, it begins to absorb heat and vaporize, lowering the indoor air temperature. The vaporized refrigerant returns to the compressor 7 along the conduit, achieving the purpose of recycling. The outer wall of the condenser tube 61 is provided with several annular grooves 611. These annular grooves 611 can reduce the local thickness of the condenser tube 61, which is beneficial for heat exchange. Several annular fins 63 are fixedly installed at the annular grooves 611, tightly connecting the annular fins 63 to the condenser tube 61 as one unit, which is beneficial for heat conduction and improves the heat dissipation effect.

[0017] like Figures 4-6 As shown, in order to improve the protection effect of the condenser tube 61, several cylindrical protective covers 62 are fixedly installed on the outer wall of the condenser tube 61. The protective covers 62 cover the outside of the annular groove 611. Since the annular groove 611 reduces the thickness of the condenser tube 61, the structural strength of this part is weakened. By protecting this weak part through the protective covers 62, the protection effect of the condenser tube 61 is effectively improved.

[0018] Furthermore, in order to avoid the protective cover 62 from hindering heat exchange, annular fins 63 are installed inside the protective cover 62 to increase the heat exchange area. Heat conduction holes 621 are provided on the protective cover 62 to ensure that the cold air after heat exchange is gathered in the inner area of ​​the protective cover 62 and then discharged outward from the heat conduction holes 621, effectively ensuring the discharge of cold air.

[0019] Secondly, several connecting pieces 631 are fixedly installed between two adjacent annular fins 63. The connecting pieces 631 can not only connect multiple annular fins 63 into one, increasing the overall strength of the fin structure, but also the large number of connecting pieces 631 are distributed in a ring shape on the outside of the condenser tube 61, which can increase the heat exchange area and effectively improve the heat exchange efficiency between indoor hot air and cold air inside the condenser tube 61.

[0020] like Figures 1-3 As shown, in order to ensure that indoor hot air can enter the air conditioner and that the cooled air after heat exchange is discharged into the room, an air outlet 3 is provided on the outer casing 1. After the indoor hot air has undergone heat exchange, the cooled air inside the air conditioner is discharged from the air outlet 3, which can cool the room. A grid plate is fixedly installed at the air outlet 3. The grid plate can reduce the probability of dust entering the air conditioner and effectively improve the dustproof performance of the air conditioner. An air inlet 4 is provided on the outer casing 1. The fan 5 fixed inside the outer casing 1 is located above the air inlet 4. The fan 5 draws the indoor hot air into the air conditioner for subsequent heat exchange.

[0021] like Figure 1 and Figure 3 As shown, in order to ensure that the compressor 7 and evaporator 8 can operate normally, an external power cord 2 is fixedly installed on the outer casing 1. The external power cord 2 is electrically connected to the control circuit board installed inside the outer casing 1. By plugging the plug of the external power cord 2 into the external socket, power can be supplied to the compressor 7 and evaporator 8. The control circuit board is equipped with a wireless transceiver, and the user can control the air conditioner with a remote control. Both the compressor 7 and evaporator 8 are electrically connected to the control circuit board through wires. When the user operates the remote control, the compressor 7 and evaporator 8 can be controlled, which is convenient to use.

[0022] like Figure 2 As shown, in order to improve the convenience of air conditioner installation, an installation socket 11 is fixedly installed on the outer casing 1. The installation socket 11 is integrally formed with the outer casing 1. The installation socket 11 is provided with a large number of snap-fit ​​grooves and snap-fit ​​structures. When installing the air conditioner, first install a wall mounting plate on the wall, and then fit the above-mentioned snap-fit ​​grooves and snap-fit ​​structures onto the wall mounting plate to fix the air conditioner to the wall, which effectively improves the convenience of its installation.

[0023] In this embodiment, the fan 5 first draws indoor hot air into the air conditioner, and then the compressor 7 pressurizes high-pressure gaseous refrigerant into the condenser 61 to facilitate heat exchange with the indoor hot air. When the liquid refrigerant enters the evaporator 8, it begins to absorb heat and vaporize, lowering the indoor air temperature. The vaporized refrigerant returns to the compressor 7 along the duct, achieving the purpose of recycling. After the hot air exchanges heat with the refrigerant inside the condenser 61, the generated cold air is discharged from the air outlet 3, thus cooling the room. During the heat exchange process, the numerous annular grooves 611 on the outer wall of the condenser 61 reduce the thickness of the condenser 61, which is beneficial for heat exchange between the cold and hot air inside and outside the condenser 61. Combined with the annular fins 63 that are in close contact with the condenser 61, the heat exchange area and heat conduction efficiency are increased, effectively improving the heat dissipation effect of the air conditioner.

[0024] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
