Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

A drain pipe assembly and an air conditioner having the same according to an embodiment of the present utility model will be described with reference to fig. 1 to 5.

As shown in fig. 2 to 5, the drain pipe assembly according to the embodiment of the present utility model includes: a drain pipe 1 and a unidirectional assembly 2. The drain pipe 1 extends along preset direction, one end of drain pipe 1 along preset direction (the end of drain pipe 1 adjacent to air conditioner indoor unit 3) is equipped with water inlet 11, the other end of drain pipe 1 along preset direction (the end of drain pipe 1 remote from air conditioner indoor unit 3) is equipped with delivery port 12, be equipped with at least one installation department 13 on the pipe wall 15 of drain pipe 1, at least one installation department 13 is arranged adjacent to water inlet 11, on installation department 13 was located to one-way subassembly 2, one-way subassembly 2 was used for with the one-way circulation of the interior gas of drain pipe 1 outside drain pipe 1. It will be appreciated that the unidirectional assembly 2 allows unidirectional flow of gas within the drain pipe 1 and in a direction from within the drain pipe 1 to outside the drain pipe 1.

According to the drain pipe assembly of the embodiment of the utility model, the mounting part 13 is arranged on the pipe wall 15 of the drain pipe 1, and the unidirectional assembly 2 is arranged on the mounting part 13 and is adjacent to the water inlet 11, so that when water is stored in the bending position of the drain pipe 1 to form the air column 4, air in the area of the air column 4 can be discharged through the unidirectional assembly 2, and condensed water generated by the air conditioner 3 can be smoothly discharged through the drain pipe 1. Therefore, the drain pipe assembly of the embodiment of the utility model has smooth drainage, can avoid water leakage of the air conditioner indoor unit 3 and has good use effect.

The inventors of the present application found that in the after-sales problem summary of the air conditioner, the air conditioner has a large proportion of water leakage problems caused by V-bends in the drain pipe 1, and it is often difficult to thoroughly solve the problem by means of after-sales treatment alone or by ordering users. Specifically, as shown in fig. 1, the existence of the V-shaped water bend of the drain pipe causes condensed water to be inevitably gathered in the V-shaped bending area, when the condensed water covers the whole section of the drain pipe 1, the air column 4 is generated immediately, and after that, the condensed water in the water receiving disc 31 forms water pressure H1, and the water at the two sides of the V-shaped water bend forms water pressure H2, and the water pressure H1 and the water pressure H2 form dynamic balance. When the water pressure H1> H2, the water receiving tray 31 is not yet full, and the B water level can pass the high point C, no water leakage is caused (the case where the V-shaped water bend is small). When the water receiving tray 31 is full and the water level B has not yet passed the high point C, water leakage is caused. When the return water bending height difference H3 is less than 47mm, the occurrence of water leakage caused by the air-holding in the drain pipe 1 can be avoided, and hidden danger of air-holding and water leakage in the drain pipe 1 exists under other conditions.

Therefore, the drain pipe assembly of the embodiment of the utility model can push the channel of the unidirectional assembly 2 open under the pressure of the air column 4 in the drain pipe 1 by arranging the unidirectional assembly 2 at the position of the drain pipe 1 adjacent to the water inlet 11, so that the air in the air column 4 can be smoothly discharged, the water leakage of the air conditioner indoor unit 3 is avoided, and the outside air can not enter the drain pipe 1 through the unidirectional assembly 2 due to the working principle of unidirectional conduction of the unidirectional assembly 2, thereby avoiding the problem of air backflow.

Alternatively, as shown in fig. 2 and 3, the mounting portion 13 may be one or more.

For example, the mounting portion 13 is one, and the mounting portion 13 is arranged adjacent to the water inlet 11 to ensure that the mounting position of the unidirectional assembly 2 is located between the water inlet 11 and the bent area of the drain pipe 1.

For example, the plurality of mounting parts 13 are arranged on the drain pipe 1 at intervals along the preset direction, the plurality of unidirectional assemblies 2 are arranged in a plurality of one-to-one correspondence with the plurality of mounting parts 13, so that the smoothness of draining of the drain pipe 1 can be further improved, when the drain pipe 1 is bent at a plurality of positions, the air in the drain pipe 1 can be better discharged, the water leakage probability of the air conditioner 3 is further avoided, and the use reliability of the air conditioner is improved.

Alternatively, as shown in fig. 3, the mounting portion 13 is arranged toward the upper side of the tube wall 15, and the unidirectional member 2 is provided on the upper side of the tube wall 15. It can be understood that when the drain pipe assembly is installed, the unidirectional assembly 2 is arranged on the upper side of the drain pipe 1, so that the gas in the drain pipe 1 can be smoothly discharged, condensed water in the drain pipe 1 can not leak out, and the use reliability of the drain pipe 1 is improved.

In some embodiments, as shown in fig. 3 and 4, the unidirectional assembly 2 is detachably connected with the mounting portion 13. Alternatively, the unidirectional assembly 2 is snapped with the mounting portion 13. It will be appreciated that the unidirectional assembly 2 may be resiliently snap-fitted to the mounting portion 13 to facilitate assembly and disassembly of the drain assembly.

Alternatively, the unidirectional assembly 2 is threadedly engaged with the mounting portion 13. For example, the outer periphery of the unidirectional component 2 is provided with an external thread, and the mounting portion 13 is provided with an internal thread, and the external thread is matched with the internal thread, so that the installation firmness of the unidirectional component 2 can be ensured.

In some embodiments, as shown in fig. 3, the mounting portion 13 is provided with a mounting groove 131, a through hole 132 is formed at the bottom of the mounting groove 131, the unidirectional component 2 is disposed through the through hole 132, and at least part of the unidirectional component 2 is fitted in the mounting groove 131. It will be appreciated that the mounting portion 13 extends towards the lumen 14 of the drain pipe 1, and the unidirectional assembly 2 is embedded into the mounting groove 131, so that the occupied space of the drain pipe assembly can be reduced, the unidirectional assembly 2 can be protected, and the probability of damage to the unidirectional assembly 2 due to external collision is reduced.

For example, the top of the unidirectional component 2 is not higher than the notch of the mounting groove 131, so that the integrity of the drain pipe component is better, the placement and management of the drain pipe component are facilitated, the occupied space of the drain pipe component is reduced, the unidirectional component 2 can be protected, and the damage probability of the unidirectional component 2 due to external collision is reduced.

In an example, the unidirectional component 2 is a unidirectional valve, which may be a unidirectional valve for unidirectional gas conduction in the prior art, and the structure of the unidirectional valve is not specifically limited in this application.

In another example, as shown in fig. 3 to 5, the unidirectional assembly 2 includes a base 22, a cover 21 and a supporting member 23, the base 22 is penetrated through the through hole 132 and is matched with the mounting groove 131, the cover 21 is arranged at one end of the base 22 adjacent to the pipe cavity 14 of the drain pipe 1, the supporting member 23 is arranged between the base 22 and the cover 21, a first hole 211 is arranged on the cover 21, a second hole 221 is arranged on the base 22, and the supporting member 23 is movable between an exhaust position and a closed position. In the exhaust position, the support 23 is spaced apart from the first and second holes 211, 221 to allow the first and second holes 211, 221 to communicate, and in the closed position, the support 23 occludes the first hole 211. It will be appreciated that when the air pressure in the drain pipe 1 reaches a certain value, the air can push the support 23 to move in a direction away from the cover 21, so that the support 23 is spaced apart from the first hole 211 and the second hole 221, and the air is led out of the drain pipe 1 through the first hole 211 and the second hole 221. When the air pressure is less than the preset value, the supporting member 23 resets and closes the first hole 211, thereby avoiding the problem of leakage of condensed water from the position of the unidirectional assembly 2.

Alternatively, as shown in fig. 3 to 5, the supporting member 23 includes a supporting body 231 and an elastic member 232, the supporting body 231 includes a guide post 2311 and a blocking portion 2312 connected to each other, the guide post 2311 is slidably disposed through the first hole 211, the blocking portion 2312 is disposed around an axial direction of the guide post 2311, one end of the elastic member 232 is connected to the seat 22, the other end of the elastic member 232 is connected to the blocking portion 2312, and the elastic member 232 has an elastic force to press the blocking portion 2312 toward the direction of the first hole 211.

Since the guide post 2311 is slidably engaged with the first hole 211, it is possible to provide a guide for the movement of the blocking portion 2312, and the reliability of the movement of the blocking portion 2312 is improved. When the support 23 is in the venting position, the spring is compressed, the blocking portion 2312 is spaced apart from the first hole 211, and the gas in the drain pipe 1 can be discharged to the outside by the one-way assembly 2. When the supporting member 23 is at the closed position, the spring is reset, the blocking portion 2312 abuts against the first hole 211, and the air in the drain pipe 1 and the air from the outside are not exchanged.

Alternatively, as shown in fig. 3 and 4, the outer periphery of the base 22 is provided with an annular groove 222, and the outer periphery of the through hole 132 forms a clamping ring 133, and the clamping ring 133 is clamped in the annular groove 222. It can be appreciated that the annular groove 222 and the through hole 132 are located on the same axis, and the annular groove 222 is clamped with the clamping ring 133, so that the unidirectional assembly 2 can be assembled conveniently, and the structure is simple in design and convenient to process and manufacture.
