Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. Although the present embodiment is described by taking a cabinet air conditioner as an example, the present invention can also be applied to other air conditioners configured with a fresh air module, such as a wall-mounted air conditioner, a central air conditioner, and the like.

It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

At present, the purpose of improving the air quality of the indoor space is achieved by introducing outdoor fresh air into the indoor space. The purpose is usually realized by configuring a fresh air module on the air conditioner, the fresh air module comprises a fresh air pipe and a fresh air machine, and under the action of the fresh air machine, outdoor fresh air enters the indoor space through the fresh air pipe, so that the purpose of improving the air quality of the indoor space is achieved. However, the fresh air duct needs to be extended to the outside through a wall, and the connecting pipe and the connecting line between the indoor unit and the outdoor unit, and the drain pipe of the indoor unit also need to be extended to the outside through a wall. When installing the air conditioner, a through-wall hole is usually reserved in the wall, and only the connecting component is usually considered in the through-wall hole. On the basis of the reasons of saving the punching cost, damaging the wall body less, being attractive and the like, the fresh air pipe can be generally considered to penetrate out of the through-wall hole, but the diameter of the fresh air pipe cannot be too large due to limited space. However, the fresh air duct with a smaller diameter can achieve a smaller fresh air intake, resulting in a limited effect of improving the air quality of the indoor space. Therefore, the first recess capable of partially accommodating the connecting assembly of the fresh air conditioner is formed in at least part of the outer side of the air inlet pipe, and when the air inlet pipe is installed, the connecting assembly is arranged at the first recess, so that the connecting assembly and the air inlet pipe can penetrate through the wall through hole while the fresh air quantity is ensured, and the air quality of an indoor space can be better improved.

First, a possible implementation of the fresh air duct assembly of the fresh air conditioner of the present invention is explained with reference to fig. 1 to 7B. Wherein, fig. 1 is a structural diagram of a fresh air pipe assembly arranged on a cabinet type fresh air conditioner according to an embodiment of the present invention, fig. 2 is a structural view of a fresh air pipe assembly connected to a fresh air module according to an embodiment of the present invention, fig. 3 is a structural view of a fresh air module according to an embodiment of the present invention, figure 4 is a block diagram of the mating of the fresh air duct assembly and the connector of one embodiment of the present invention (one), figure 5 is a block diagram of the mating of the fresh air duct assembly and the connector of one embodiment of the present invention (ii), fig. 6 is a structural view showing a connection member of a fresh air duct assembly according to an embodiment of the present invention, fig. 7A is a schematic view showing a connection member and an air inlet duct simultaneously passing through a wall penetration hole and the air inlet duct being a nearly circular duct according to an embodiment of the present invention, fig. 7B is a schematic view of the connection assembly and the air inlet duct simultaneously passing through the wall opening, wherein the air inlet duct is a crescent-shaped duct according to an embodiment of the present invention.

As shown in fig. 1 to 5, 7A and 7B, the cabinet fresh air conditioner includes an indoor unit and an outdoor unit, the indoor unit and the outdoor unit are connected via a connection line and a connection pipe, the indoor unit is provided with a drain pipe, and the connection line, the connection pipe and the drain pipe all need to penetrate through a wall body and extend from indoor to outdoor. That is, the connection assembly 4 in the present application includes at least a connection pipe and a connection line between the indoor unit and the outdoor unit of the air conditioner, and a drain pipe of the indoor unit. During installation, the connector pipes, the connecting lines, and the drain pipes are typically bundled together to form a structure having a generally circular or oval cross-section, and then extended out of the room through the wall holes 6.

The air-conditioning indoor unit comprises a shell 1, a fresh air module 2 is configured in the air-conditioning indoor unit, and a fresh air interface 22 is arranged in the air-conditioning indoor unit. The fresh air duct assembly 3 comprises a connecting pipe 31 and an air inlet pipe 32 which are connected with each other, and the first end of the connecting pipe 31 can be connected with the fresh air interface 22 through clamping, screwing, splicing and other modes, so that the connecting pipe 31 is communicated with the fresh air module 2. The second end of the connecting pipe 31 is connected with the first end of the air inlet pipe 32, the second end of the air inlet pipe 32 extends out of the room and is communicated with the outside, so that outdoor fresh air can enter the indoor space through the air inlet pipe 32, the connecting pipe 31 and the fresh air module 2 in sequence, and the purpose of improving the air quality of the indoor space is achieved. It should be noted that the second end of the connecting pipe 31 and the first end of the air inlet pipe 32 may be directly connected, or may be connected through a connecting member separately provided.

A first recess 321 is formed circumferentially outwardly of the air inlet duct 32, the first recess 321 being capable of partially receiving the connection assembly 4. Thus, when the radial dimension of the through-wall hole 6 is fixed, the diameter of the air inlet pipe 32 can be increased as much as possible by removing a part of the space occupied by the connecting assembly 4, and only the connecting assembly 4 needs to be arranged at the first recess 321, so that the connecting assembly 4 and the air inlet pipe 32 can simultaneously penetrate through the through-wall hole 6 while ensuring the fresh air volume. Through such a mode of setting, need not to punch in addition, can realize bigger draught area as far as possible through the limited space of through-wall hole 6, introduce more new trend for the interior space to can improve the air quality of interior space better.

It should be noted that the first recess 321 may be formed inward on the outer side of the air inlet duct 32 along the circumferential direction, the first recess 321 may be formed inward only at the positions of the wall through holes 6 and the front and rear portions of the wall through holes 6, the first end of the air inlet duct 32 may not be formed at the position close to the connecting pipe 31, and the first recess 321 is formed inward on the outer side of the remaining portion of the air inlet duct 32. For example, when the first recesses 321 are formed on the outer side of the air inlet duct 32 all along the circumferential direction thereof, the second end of the connection pipe 31 is connected to the first end of the air inlet duct 32 by a connection member having a recess structure similar to the first recesses 321 formed in the outer side of a portion adjacent to the first end of the air inlet duct 32, and the second end of the connection member is connected to the first end of the air inlet duct 32 by means of insertion, clamping, or the like. The forming position of the first recess 321 on the air inlet pipe 32 can be flexibly selected by those skilled in the art according to the specific application scenario, as long as the connecting assembly 4 and the air inlet pipe 32 can simultaneously pass through the wall through hole 6 while ensuring the fresh air volume.

As shown in fig. 1, 2, 7A and 7B, the connection pipe 31 is a threaded hose, which can be extended and retracted in any direction, and the extending direction of the connection pipe 31 can be switched, so that when installing, regardless of the distance and direction of the indoor unit of the cabinet type fresh air conditioner relative to the wall through hole 6, the connection pipe 31 and the air inlet pipe 32 can be installed by extension and retraction and twisting of the threaded hose, and the installation is more convenient. Obviously, the connection pipe 31 can be configured as a common hose, and those skilled in the art can flexibly select the hose according to the specific application scenario as long as the connection pipe 31 and the air inlet pipe 32 can be conveniently installed.

As shown in fig. 2, 4, 5, 7A and 7B, the cross section of the portion of the air inlet duct 32 where the first recess 321 is formed is configured as a crescent, and both ends of the crescent are configured as arc segments. For example, the crescent is a bellows or a smooth tube. The both ends of ordinary crescent are set up to relatively sharp-pointed shape usually, compare with ordinary crescent, and the area of the crescent of this application can be bigger some to just also increased air-supply line 32's draught area, can allow more new trend to pass through. When the air conditioner is installed, the connecting assembly 4 is arranged at the concave part of the crescent shape, so that the connecting assembly 4 and the air inlet pipe 32 simultaneously pass through the wall through hole 6, more fresh air can be allowed to enter the indoor space through the air inlet pipe 32 and the connecting pipe 31, and the indoor space can be improved better.

It should be noted that the cross section of the air inlet duct 32 may not be configured as a crescent, for example, the cross section of the air inlet duct 32 is configured as a rectangle with a certain side inwardly forming the first recess 321 capable of partially accommodating the connection assembly 4, etc., and those skilled in the art can flexibly select the shape of the air inlet duct 32 according to the specific application scenario as long as the connection assembly 4 and the air inlet duct 32 can simultaneously pass through the wall through hole 6 while ensuring the fresh air volume.

To better illustrate the present invention, the inventors have conducted a series of validation tests in which at least a portion of the cross-section of the air inlet duct 32 is formed in a crescent shape to allow more fresh air to pass through. As shown in fig. 7A and 7B, taking a circular hole with a diameter of 60mm of the through-wall hole 6 as an example, the cross section of the connecting assembly 4 after being wrapped is approximately oval, and the length of the major axis of the oval is approximately 45 mm. The inventors have conducted experiments under two conditions, respectively: (1) the air inlet pipe 32 is provided as an approximately circular pipe, and the diameter of the air inlet pipe 32 is approximately 32 mm; (2) the portion of the air inlet duct 32 is configured as a crescent. The results of the specific experiments are shown in table 1 below.

TABLE 1

The gear, the rotating speed, the current, the air volume and the input power are all working parameters of the fresh air fan of the fresh air module 2.

It can be seen from table 1 that when the gear and the rotation speed of the fresh air blower are the same, at least a part of the air inlet pipe 32 is set as a crescent pipe, so that the air volume is larger. It can be shown that the air inlet duct 32 is at least partially crescent-shaped to allow more fresh air to enter the indoor space through the air inlet duct 32, thereby improving the indoor space.

As shown in fig. 1 and 2, the radial dimension of the second end of the connection pipe 31 is slightly smaller than the radial dimension of the first end of the air inlet pipe 32, and the connection of the connection pipe 31 and the air inlet pipe 32 is achieved by the friction between the thread structure formed on the outer surface of the threaded hose and the inner wall of the air inlet pipe 32 by inserting the second end of the connection pipe 31 into the first end of the air inlet pipe 32. Obviously, it is also possible to insert the first end of the air inlet duct 32 into the second end of the connecting duct 31 by making the radial dimension of the second end of the connecting duct 31 slightly larger than the radial dimension of the first end of the air inlet duct 32, so as to also enable the connection of the connecting duct 31 with the air inlet duct 32. Certainly, the second end of the connecting pipe 31 can also be connected with the air inlet pipe 32 through other modes such as clamping, magnetic adsorption and screwing, specifically, for example, the second end of the connecting pipe 31 and the first end of the air inlet pipe 32 are respectively provided with a magnetic adsorption component (such as a ring magnet) and other components (such as an iron ring) capable of being adsorbed by the magnetic adsorption component, the connecting pipe 31 and the air inlet pipe 32 are connected with each other through the magnetic adsorption mode, and the like, the skilled person can flexibly select the specific mode for realizing the connection of the connecting pipe 31 and the air inlet pipe 32 according to the specific application scene, as long as the two can be connected.

As shown in fig. 2, 4 and 5, the fresh air duct assembly 3 further includes a hood 33, the hood 33 is integrally formed at the second end of the air inlet duct 32, for example, the hood 33 and the air inlet duct 32 are both made of plastic such as ABS or PP. The blast cap 33 arranged in this way can be more firmly arranged at the second end of the air inlet pipe 32, and outdoor fresh air enters the indoor space through the blast cap 33, the air inlet pipe 32, the connecting pipe 31, the fresh air interface 22 and the fresh air module 2 in sequence, so that the air quality of the indoor space is improved. In addition, when the connecting pipe 31 and the hood 33 are manufactured, only one die is needed to be arranged, so that the manufacturing process is simplified, and the cost is saved. Of course, the second end of the air inlet duct 32 may be provided without the hood 33.

As shown in fig. 4 and 5, a second recess 331 is formed in a circumferential outer side of the hood 33, and the second recess 331 is capable of partially accommodating the connecting assembly 4. This also enables the hood 33 to be engaged with the connection assembly 4 to better position the hood 33 on the second end of the air inlet duct 32. Of course, the second recess 331 may not be formed on the outside of the hood 33, and when it is installed, the length of the inlet duct 32 is slightly longer than that of the connection unit 4, and the second end of the inlet duct 32 protrudes from the connection unit 4, so that the hood 33, on which the second recess 331 is not formed, does not interfere with the connection unit 4 even at the second end of the inlet duct 32.

Because the outdoor environment is relatively complicated, especially in windy weather, sundries such as leaves, branches, plastic bags and the like can float in the outdoor environment, and if the sundries enter the air inlet pipe 32 and then enter the fresh air module 2 through the connecting pipe 31, the indoor unit of the air conditioner can be possibly caused to break down. In addition, in rainy and snowy weather, if rain and snow enter the air inlet pipe 32 and then enter the fresh air module 2 through the connecting pipe 31, the indoor unit of the air conditioner can also be caused to be in failure.

In order to ensure the normal operation of the indoor unit of the air conditioner, as shown in fig. 2, 4 and 5, the end of the hood 33 away from the air inlet pipe 32 is provided with a grille structure 332, the grille structure 332 is distributed over the entire end of the hood 33, and fresh air entering the air inlet pipe 32 is firstly filtered by the grille structure 332, so that impurities outside the room can be effectively prevented from entering the air inlet pipe 32. The upper edge of the end of the hood 33 away from the air inlet duct 32 extends outwardly to form a shielding edge 333, and the shielding edge 333 is substantially an arc-shaped sheet-like structure and has a length substantially covering the upper edge of the end of the hood 33, so as to better prevent rain, snow and the like from entering the air inlet duct 32. Through the arrangement mode, sundries and rain and snow can be prevented from entering the air inlet pipe 32, and normal operation of the indoor unit of the air conditioner is ensured.

It should be noted that the end of the hood 33 remote from the air inlet duct 32 may not be provided with the grill structure 332 or the blocking rim 333. When the grill structure 332 is not arranged, a filter screen can be arranged in the air inlet pipe 32, so that even if sundries enter the air inlet pipe 32, the sundries cannot further enter the fresh air module 2, and the normal operation of the indoor unit of the air conditioner cannot be influenced. When the shielding edge 333 is not arranged, the air inlet pipe 32 can be installed obliquely downwards when the air inlet pipe 32 is installed, so that even if rain and snow enter the air inlet pipe 32, the rain and snow can be prevented from further entering the connecting pipe 31 and then entering the fresh air module 2, and the normal operation of the indoor unit of the air conditioner cannot be influenced. Those skilled in the art can flexibly select a specific setting mode of the hood 33 according to a specific application scenario as long as normal operation of the indoor unit of the air conditioner can be ensured.

As shown in fig. 1 to 3 and 6, the fresh air duct assembly 3 further includes a connecting member 5, a first end of the connecting member 5 is connected to the fresh air interface 22, and a second end of the connecting member 5 is connected to a first end of the connecting pipe 31, so that the connecting pipe 31 and the air inlet pipe 32 are connected to the fresh air interface 22, that is, the connecting pipe 31 is communicated with the fresh air module 2, and the outdoor fresh air can enter the indoor space through the air inlet pipe 32, the connecting pipe 31, the connecting member 5 and the fresh air module 2 in sequence.

In this embodiment, as shown in fig. 1 to 3 and 6, the fresh air module 2 is provided with a housing 21, and the fresh air interface 22 is disposed on the housing 21. The first end of connecting piece 5 is provided with four L type through-holes 51, correspondingly, is provided with four fixture blocks 221 rather than assorted on the new trend interface 22, like this, with the first end of connecting piece 5 after pegging graft to new trend interface 22, just can make fixture block 221 and L type through-hole 51 cooperate through the mode of revolving soon to realize connecting piece 5 and new trend interface 22 continuous, convenient and reliable. After the first end of the connecting piece 5 is connected with the fresh air interface 22, the second end of the connecting piece penetrates out of the indoor unit of the air conditioner. The outer wall of the second end of the connecting piece 5 is provided with a first threaded section 52, and the first threaded section 52 is matched and connected with the connecting pipe 31 which is arranged into a threaded hose, so that the connecting pipe 31 is arranged at the second end of the connecting piece 5 in a threaded manner. When the connection pipe 31 is not configured as a threaded hose, the inner wall of the first end of the connection pipe 31 is provided with a second threaded section matching with the first threaded section 52, so that the connection pipe 31 and the connection member 5 can be screwed together. Obviously, the first end of connecting piece 5 can also meet with new trend interface 22 through modes such as spiro union, magnetic adsorption, the second end of connecting piece 5 can also meet with connecting pipe 31 through modes such as joint, magnetic adsorption, the skilled person in the art can be according to the nimble selection of specific application scene.

Obviously, the fresh air interface 22 may also be disposed on the casing 1 of the indoor unit of the air conditioner, and the outer shell 21 of the fresh air module 2 is communicated with the fresh air interface 22 on the casing 1, and those skilled in the art can flexibly select the fresh air interface according to a specific application scenario.

It should be noted that, the fresh air duct assembly 3 may also have no connecting piece 5, and the connecting pipe 31 is directly connected to the fresh air interface 22, so as to communicate the connecting pipe 31 with the fresh air module 2. The technical personnel in the field can flexibly select the specific setting mode of the fresh air pipe assembly 3 according to the specific application scene as long as outdoor fresh air can be guided into the indoor space.
