In the related art, a water tank for recovering condensed water is provided inside an air conditioner. In order to avoid that the water pressure in the water tank is too high and the water tank is damaged, a safety valve is usually arranged on the water tank, and an overflow port of the safety valve is usually connected with a hose for guiding out condensed water.

However, when the water pressure in the water tank exceeds the set pressure value of the safety valve, the condensed water sprayed from the overflow port of the safety valve drives the hose to swing, so that the condensed water splashes everywhere. And the splashed condensed water can affect the normal operation of the internal equipment of the air conditioner.

In order to solve the technical problems, the embodiment of the application provides a pipe joint, a drainage assembly and an air conditioner, which can prevent condensed water sprayed from a safety valve of the air conditioner from splashing and ensure normal operation of internal equipment of the air conditioner.

The pipe joint, the drainage assembly and the air conditioner provided by the embodiment of the application are described in detail below with reference to the accompanying drawings.

The air conditioner provided by the embodiment of the application can be any one of a wall-mounted air conditioner indoor unit, a cabinet air conditioner indoor unit, an air conditioner, a ceiling air conditioner indoor unit or a mobile air conditioner, and the embodiment of the application is not particularly limited.

The air conditioner comprises a water tank, wherein the water tank is connected with a condensate pipe in the air conditioner and is used for carrying out centralized recycling on condensate water, so that the waste of water resources caused by directly discharging the condensate water outdoors is avoided. The recovered condensed water can be used for supplementing water for an air conditioner, and supplementing domestic water is reduced. For example, the condensed water recovered in the water tank can be used as a water source for air conditioner humidification, and the recovered condensed water is used as the water source for air conditioner humidification, so that a user can not add water into the air conditioner at any time, the humidification function of the air conditioner is more intelligent, and the experience of the user is effectively improved.

In order to avoid damage to the water tank or other equipment in the air conditioner caused by excessive water pressure in the water tank of the air conditioner, the air conditioner further comprises a safety valve. The relief valve is typically mounted on top of the tank. The safety valve is provided with an overflow port, when the water pressure in the water tank exceeds the set pressure value of the safety valve, condensed water is discharged from the overflow port of the safety valve, and the water pressure in the water tank is reduced, so that the water pressure in the water tank can be ensured to be always kept within a safety range.

In addition, the air conditioner further includes a drain assembly, referring to fig. 1 and 2, which includes a pipe joint 200, a hose 300, and a drain pipe 400, the hose 300 being connected to an overflow port (not shown) of the safety valve.

As shown in fig. 3, the pipe joint 200 includes a joint body 210 and a connection assembly 220. The joint body 210 includes a pipe body 211 and a first connection end 212 connected, and the connection assembly 220 includes a second connection end 221 and a connection piece 222, wherein the second connection end 221 is connected to an end of the pipe body 211 remote from the first connection end 212 through the connection piece 222. One end of the hose 300 is connected to the second connection end 221, the other end of the hose 300 is connected to the overflow port of the safety valve, one end of the drain pipe 400 is connected to the first connection end 212, and the other end of the drain pipe 400 is disposed outside the housing of the air conditioner.

The second connecting end 221 is connected to the end of the pipe body 211 far away from the first connecting end 212 through the connecting piece 222, so that the second connecting end 221 can be connected with an overflow port of the safety valve through the hose 300. After the condensed water sprayed from the overflow port of the safety valve flows through the hose 300, it can enter the pipe body 211 and the first connection end 212 through the second connection end 221, and finally be discharged to the outside of the housing of the air conditioner through the drain pipe 400 connected to the first connection end 212. Therefore, the application can prevent the condensed water sprayed from the safety valve of the air conditioner from splashing, and ensure the normal operation of the internal equipment of the air conditioner.

The first connection end 212 of the joint body 210 is connected to the drain pipe 400. It will be appreciated that, for convenience of the installer to determine whether the first connection end 212 and the drain pipe 400 are in place, the diameter of the first connection end 212 may be set smaller than the diameter of the pipe body 211, as shown in fig. 2, such that the junction between the first connection end 212 and the pipe body 211 forms a step, and thus, when the installer installs the drain pipe 400 around the step, it is known that the first connection end 212 and the drain pipe 400 are in place.

Further, to improve the tightness of the connection of the first connection end 212 to the drain pipe 400, in some embodiments, the outer circumference of the first connection end 212 may be provided with at least one protrusion 2121 around the axis of the first connection end 212. For example, two protrusions 2121 may be provided at intervals as shown in fig. 3, and of course, four, five, or more protrusions 2121 may be provided according to actual circumstances. The spacing distance between the protrusions 2121 may be flexibly set according to the length of the first connecting end 212 and the like. By providing the protrusions 2121, when the first connection end 212 is connected to the drain pipe 400, the protrusions 2121 can expand against the inner wall of the drain pipe 400, making the connection between the first connection end 212 and the drain pipe 400 tighter.

A water pan 100 is generally installed in the air conditioner, for example, the water pan 100 is installed at the lower part of the water tank of the air conditioner to receive condensed water which is not completely collected by the water tank and condensed water generated by the water tank itself. Referring to fig. 1 and 3, the water pan 100 may be connected with the pipe body 211 of the joint body 210. Illustratively, the drip tray 100 may be provided with a drain hole (not shown) through which the pipe joint 200 is inserted.
