The embodiment of the application provides an air conditioner, and aims to solve one or more technical problems of unsatisfactory heat dissipation effect, low energy utilization rate and easy chassis icing caused by unreasonable structural design of the existing air conditioner.

As shown in fig. 1 to 7, the air conditioner provided in the embodiment of the present application may be a window air conditioner, or may be other types of air conditioners, which is not limited herein.

An air conditioner, i.e., an air conditioner (room air conditioner), is used to provide a unit for treating air temperature changes in a space region (typically, a closed space). The function of the device is to adjust the parameters of temperature, humidity, cleanliness, air flow rate and the like of the air in the room (or the closed space or the area) so as to meet the requirements of human comfort or the technological process.

In some embodiments of the present application, referring to fig. 1 to 3, an air conditioner 100 includes a chassis 10, a compressor 80, a water pan 20, a throttling device 30, a first supercooling pipe 41, a second supercooling pipe 42, a radiating pipe 51, an evaporator 60, and a condenser 70. The chassis 10 is used for mounting and carrying functional modules such as a compressor 80, an air duct assembly (not shown), an evaporator 60, and a condenser 70. It should be noted that the throttle device 30 may be a throttle valve, and this structure is advantageous in simplifying the structure of the air conditioner 100. The specific structure of the functional modules such as the compressor 80, the air duct assembly, the water pan 20, the throttling device 30, the evaporator 60, and the condenser 70 in the present application is not a major improvement of the present application, and those skilled in the art may select an adaptive structure according to specific needs, which is not limited herein.

In this application, the chassis 10 includes an indoor side 12 and an outdoor side 11, and the outdoor side 11 of the chassis 10 is provided with a drain hole (not shown). Specifically, the indoor side 12 of the chassis 10 is higher than the outdoor side 11, and this structure is provided to facilitate drainage of the accumulated water of the indoor side 12 to the outdoor side 11. The outdoor side 11 of the base pan 10 can store a certain volume of water so that the outdoor fan can radiate heat by using condensed water when rotating. The air conditioner 100 further includes a drain valve (not shown) for opening or closing the drain hole, that is, controlling the drain hole to be opened or closed by changing the position of the drain valve. Illustratively, a drain valve is rotatably disposed on the chassis 10 and is rotatable over the drain hole to close the drain hole.

In the present application, the first supercooling pipe 41, the second supercooling pipe 42, and the condenser 70 are disposed at the outdoor side 11. The evaporator 60 and the water pan 20 are disposed on the indoor side 12, and the water pan 20 is used for receiving condensed water and draining the condensed water in the water pan 20 to the outdoor side 11. Specifically, the water pan 20 is located above the indoor side 12 of the chassis 10 for receiving and draining condensate on the indoor side evaporator 60 into the outdoor side 11 chassis 10. The first and second supercooling pipes 41 and 42 spiral on the chassis 10 of the outdoor side 11. The first and/or second supercooling pipes 41 and 42 are at least partially disposed adjacent to the drain hole. Illustratively, the first supercooling pipe 41 is disposed to fit the chassis 10, and the first supercooling pipe 41 is disposed at least partially adjacent to the drain hole. The second supercooling pipe 42 is disposed to fit the chassis 10, and the second supercooling pipe 42 is disposed at least partially adjacent to the drain hole. Thereby being beneficial to improving the heat exchange effect of the first and second supercooling pipes 41 and 42 and accumulated water (condensed water or chilled water) on the chassis 10.

It can be appreciated that when the air conditioner 100 operates in the cooling mode, more condensed water is generated on the evaporator 60, the water pan 20 is disposed below the evaporator 60, and the condensed water on the evaporator 60 can drop into the water pan 20 under the action of gravity, so that the condensed water on the water pan 20 is drained to the outdoor side 11 of the chassis through the drainage structure on the water pan 20. The accumulated water on the outdoor side 11 can be discharged out of the chassis 10 through the drain hole. Specifically, when the drain hole is opened, the accumulated water on the outdoor side 11 of the bottom chassis 10 may be drained out of the bottom chassis 10 through the drain hole. When the drain holes are closed, the accumulated water on the outdoor side 11 of the chassis 10 cannot drain out of the chassis 10 through the drain holes.

In this application, referring to fig. 1, both ends of the first supercooling pipe 41 are respectively communicated with the outlet of the condenser 70 and the inlet of the radiating pipe 51, and configured to exchange heat with condensed water flowing into the outdoor side 11; both ends of the second supercooling pipe 42 are respectively communicated with the outlet of the radiating pipe 51 and the inlet of the throttling device 30, and configured to be heat-exchanged with the condensed water flowing into the outdoor side 11; the outlet of the throttle device 30 communicates with the inlet of the evaporator 60, and the outlet of the evaporator 60 communicates with the inlet of the condenser 70. It should be noted that, in the present application, communication may be direct communication or indirect communication through one or more media, which is not limited herein.

The first supercooling pipe 41 is configured to exchange heat with the condensed water flowing into the outdoor side 11, that is, the refrigerant in the first supercooling pipe 41 can exchange heat with the condensed water. Specifically, at least part of the first supercooling pipe 41 is located in the condensed water. When the refrigerant flows through the first supercooling pipe 41, it must pass through the portion of the first supercooling pipe 41 located in the condensed water, so that the refrigerant in the first supercooling pipe 41 can exchange heat with the condensed water. Similarly, the second supercooling pipe 42 is configured to exchange heat with the condensed water flowing into the outdoor side 11, that is, the refrigerant in the second supercooling pipe 42 can exchange heat with the condensed water. Specifically, at least a portion of the second superheat tube 42 is located within the condensate. When the refrigerant flows through the second supercooling pipe 42, it must pass through a portion of the second supercooling pipe 42 located in the condensed water, so that the refrigerant in the second supercooling pipe 42 can exchange heat with the condensed water. Further, the first and second supercooling pipes 41 and 42 are disposed in parallel, and the second supercooling pipe 42 is located at a side of the first supercooling pipe 41 near the indoor side 12, thereby being beneficial to further improving the heat exchanging effect of the first and second supercooling pipes 41 and 42. Further, the distance between the second supercooling pipe 42 and the drain hole is smaller than that between the first supercooling pipe 41 and the drain hole, that is, the second supercooling pipe 42 is closer to the drain hole than the first supercooling pipe 41, which is advantageous in further avoiding the drain Kong Jiebing.

Specifically, one end of the first supercooling pipe 41 is connected to the outlet end of the condenser 70, so that the refrigerant in the condenser 70 can flow into the first supercooling pipe 41 through the outlet of the condenser 70. The other end of the first supercooling pipe 41 is connected to the inlet end of the radiating pipe 51, so that the refrigerant in the first supercooling pipe 41 can enter the radiating pipe 51 through the inlet end of the radiating pipe 51. Similarly, one end of the second supercooling pipe 42 is connected to the outlet end of the radiating pipe 51, and the other end of the second supercooling pipe 42 is connected to the inlet end of the throttling device 30, so that the refrigerant in the radiating pipe 51 can flow out through the outlet end of the radiating pipe 51 and into the second supercooling pipe 42, and then flows into the throttling device 30 through the second supercooling pipe 42. In the present application, the outlet (or outlet) and the inlet (or inlet) are named according to the flow direction of the refrigerant in the cooling mode. Taking the condenser 70 as an example, when the air conditioner 100 operates in the cooling mode, the refrigerant flows into the condenser 70 through the inlet end of the condenser 70, and the refrigerant in the condenser 70 flows into the first supercooling pipe 41 through the outlet end of the condenser 70. When the air conditioner 100 operates in the cooling mode, the refrigerant flows into the condenser 70 through the first supercooling pipe 41, that is, the flow direction of the refrigerant is changed when the air conditioner 100 operates in the cooling mode, the refrigerant in the first supercooling pipe 41 enters the condenser 70 through the outlet end of the condenser 70, and then flows out of the condenser 70 through the inlet end of the condenser 70.

The outdoor side 11 of the chassis 10 is provided with the first supercooling pipe 41 and the second supercooling pipe 42, and the first supercooling pipe 41 and the second supercooling pipe 42 are communicated through the radiating pipe 51, and the first supercooling pipe 41 and the second supercooling pipe 42 are both configured to exchange heat with condensed water flowing into the outdoor side 11. When the air conditioner operates in the cooling mode, the refrigerant sequentially flows through the condenser 70, the first cooling pipe 41, the heat dissipation pipe 51, the second cooling pipe 42, the throttling device 30 and the evaporator 60, and the condensed water on the outdoor side 11 of the chassis 10 cools the refrigerant flowing through the first cooling pipe 41, so that the refrigerant with lower temperature enters the heat dissipation pipe 51, and more heat can be taken away when the refrigerant flows through the heat dissipation pipe 51, thereby being beneficial to improving the heat dissipation effect of the air conditioner 100; in addition, the refrigerant heated by the heat dissipating tube 51 flows through the second supercooling tube 42 to be cooled again by the condensed water of the outdoor side 11, and flows into the evaporator 60 after being cooled again, which is beneficial to improving the refrigerating effect and improving the energy utilization rate.

The outdoor side 11 of the chassis 10 is provided with the first supercooling pipe 41 and the second supercooling pipe 42, and the first supercooling pipe 41 and the second supercooling pipe 42 are communicated through the radiating pipe 51, and the first supercooling pipe 41 and the second supercooling pipe 42 are both configured to exchange heat with condensed water flowing into the outdoor side 11. During the air conditioning operation heating mode, the refrigerant flows through the evaporator 60, the throttling device 30, the second cooling pipe 42, the heat dissipating pipe 51, the first cooling pipe 41 and the condenser 70 in this order. The temperature is risen after the refrigerant flows through the radiating pipe 51, and the refrigerant with higher temperature can heat the chilled water on the outdoor side 11 of the chassis 10 when flowing through the first supercooling pipe 41, thereby effectively preventing the chilled water on the chassis 10 from freezing, ensuring that the drainage hole is smoothly drained, and improving the energy utilization rate.

In some embodiments of the present application, when the air conditioner is in the cooling mode, the drain hole is in a closed state. This structural arrangement enables accumulation of a certain volume of condensed water on the outdoor side 11 of the chassis 10, which is advantageous for improving the cooling effect when the refrigerant flows through the first and second supercooling pipes 41 and 42, and further improving the refrigerating effect and the energy utilization rate.

In some embodiments of the present application, when the air conditioner operates in the heating mode, the drain hole is in an open state. It will be appreciated that when the air conditioner is operating in the cooling mode, the temperature of the outdoor side 11 of the chassis 10 is relatively low and water accumulation on the chassis 10 tends to freeze on the chassis 10. The drain hole is in an open state, so that accumulated water on the chassis 10 can be timely drained out of the chassis 10, the phenomenon that drainage is not smooth due to the blocking of drainage Kong Jiebing is further avoided, and the stability and the energy utilization rate of the air conditioner 100 are improved.

In some embodiments of the present application, the air conditioner 100 further includes a four-way valve 90. The exhaust port 81 and the return port 82 of the compressor 80 are communicated with the four-way valve 90, and the compressor 80 is respectively communicated with the inlet of the condenser 70 and the outlet of the evaporator 60 through the four-way valve 90. Specifically, the four-way valve 90 includes a high pressure line port, a low pressure line port, a condenser, a port, and an evaporator port. The high pressure pipe interface is for communication with a discharge port 81 of the compressor 80, the low pressure pipe interface is for communication with a return air port 82 of the compressor 80, the condenser interface is for communication with an inlet of the condenser 70, and the evaporator interface is for communication with an outlet of the evaporator 60.

In some embodiments of the present application, referring to fig. 2 and 4 to 6, the air conditioner 100 further includes an electric control box 50, and the heat dissipating tube 51 is disposed in the electric control box 50. The variable frequency air conditioner 100 has serious heat generation and poor heat dissipation effects of components in the electric control box 50 during use. According to the embodiment, the radiating pipe 51 is arranged in the electric control box 50, and the cooled refrigerant flows into the radiating pipe 51 to effectively take away heat in the electric control box 50, so that the radiating effect of the electric control box 50 is improved.

It will be appreciated that the placement of the radiating pipe 51 within the recess of the radiator 55 is advantageous for improving the stability of the air conditioner 100. The electric control plate 52 heats seriously, and the radiator 55 is attached to the electric control plate 52, so that the radiating effect can be further improved. Specifically, the electronic control box 50 further includes an upper housing 53 and a lower housing 54. The heat sink 55 includes a first heat sink 551, a second heat sink 552, and a third heat sink 553. The first cooling fins 551 and the second cooling fins 552 are oppositely arranged, a first groove is formed in one surface of the first cooling fins 551 opposite to the second cooling fins 552, a second groove is formed in one surface of the second cooling fins 552 opposite to the first cooling fins 551, and the first groove and the second groove are spliced to form the groove. Illustratively, the first groove and the second groove are semi-circular grooves. The heat dissipating tube 51 is a U-shaped tube, and the heat dissipating tube 51 is fitted in the groove. The first heat sink 551 and the second heat sink 552 sandwich the heat pipe 51, and the first heat sink 551, the second heat sink 552, and the heat pipe 51 are fixed to the lower case 54. The electric control plate 52 and the third cooling fins 553 are fixed on the upper shell 53, the third cooling fins 553 are located on one side of the electric control plate 52 away from the upper shell 53, and the third cooling fins 553 are attached to the electric control plate 52. The first heat sink 551, the second heat sink 552, and the third heat sink 553 are stacked in this order in the direction in which the lower case 54 is directed toward the upper case 53. The upper cover of the electric control board 52 is also provided with a wiring groove, the electric control board 52 can be preassembled on the upper cover plate in advance and the wiring is carried out, so that the time of the assembly line body is shortened, and the production efficiency is improved.
