Detailed Description

Reference will now be made in detail to embodiments of the present invention, 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 invention and should not be construed as limiting the invention.

As shown in fig. 1 to 5, the cabinet assembly according to the embodiment of the present invention is used for an indoor unit of an air conditioner.

The housing assembly of the embodiment of the present invention includes a housing 1, a cover 202, and an electronic control board 201.

An electric control installation part is formed on a part of the surface of the casing 1, and an accommodating space is formed in the casing 1 and used for accommodating a heat exchanger of an indoor unit of an air conditioner. The cover 202 is covered outside the electric control installation part, and an electric control installation space is defined between the cover 202 and the casing 1. The electric control board 201 is disposed in the electric control installation space, and the electric control board 201 can be electrically connected with the wires.

The electric control board 201 can be electrically connected to the wires, which is understood to mean that when an electrical component (e.g., a motor) is installed in the cabinet 1, the wires of the electrical component can be electrically connected to the electric control board 201; when no electrical components are mounted in the cabinet 1, no wires are electrically connected to the electronic control board 201.

Therefore, when the air conditioner indoor unit with the shell assembly provided by the embodiment of the invention is assembled, the wires of the electric elements arranged in the shell can be directly electrically connected with the electric control board on the surface of the shell. After the conducting wire is electrically connected with the electric control board, the cover body is covered on the electric control installation part.

In the related art, an electric control box of an air conditioner indoor unit is embedded at the top or the side surface of a casing, and the problems of low production efficiency and high production cost exist.

The air conditioner indoor unit with the shell component provided by the embodiment of the invention has the advantages that the electric control installation part is arranged on the surface of the shell, and when conducting wires are electrically connected with the electric control board, the electric connection efficiency of the electric elements in the shell and the electric control board can be effectively improved, so that the production efficiency of the whole machine is effectively improved, and the production cost of the whole machine is reduced.

Therefore, the air conditioner indoor unit with the shell component provided by the embodiment of the invention has the advantages of high production efficiency of the whole machine, low production cost and the like.

The cover 202 and the electronic control board 201 are part of the electronic control assembly 2 of the housing assembly.

In some embodiments, a portion of the outer surface of the housing 1 forms an electrically controlled mount, the housing 1 having a wire via 102 through which a wire passes.

In the related art, an electric control box of an air conditioner indoor unit is embedded at the top or the side surface of a casing, and the production efficiency of the whole machine is low due to the limited operation space in the casing. In addition, due to the limitation of the internal structure of the shell, the problem of complex wiring is also caused, the phenomenon of wiring dislocation and reworking is easy to occur, and the production cost of the whole machine is increased. In addition, the complicated wiring can also lead to when line fault occurs, the electric control assembly 2 (the electric control box and the electric control board arranged in the electric control box) needs to be integrally disassembled, and then fault investigation, replacement and maintenance are carried out, so that the maintenance operation is time-consuming and labor-consuming.

Therefore, when the air conditioner indoor unit with the shell assembly is assembled, the wires of the electric elements arranged in the shell can be directly penetrated out from the wire through holes, and the wires are electrically connected with the electric control board outside the shell. After the conducting wire is electrically connected with the electric control board, the cover body is covered outside the electric control installation part.

The electric connection between the lead and the electric control board is carried out on the outer side of the shell, so that the operation space is larger, the electric connection efficiency between the electric elements in the shell and the electric control board can be effectively improved, and the production efficiency of the whole machine is effectively improved; in addition, the outer side of the shell is little or even no interference of other parts, so that the wiring of the lead wire passing through the wire passing hole can be simpler, the phenomenon of wiring error and reworking can be reduced or even avoided, the production cost of the whole machine can be effectively reduced, and the production efficiency of the whole machine can be further improved. In addition, the wiring is simple, so that later maintenance is more convenient, and the electric control board is arranged outside the shell, so that maintenance personnel can maintain the shell more conveniently.

In addition, in the related art, as the wiring is protected by structural members such as metal plates, the fresh air port is shielded, and part of functions are lost, so that the actual user experience is greatly reduced. The electric control component provided by the embodiment of the invention is arranged outside the shell, so that the problems can be avoided, and the use experience of a user can be effectively improved.

Alternatively, the electrically controlled mounting portion is formed by a part of the outer surface of the side plate 101 of the casing 1. In other words, the electronic control board is disposed on an outer side of the casing, which may be a front side, a rear side, a left side, or a right side of the casing for a casing having a rectangular cross section of the casing. For a housing with a circular cross section, the outer side surface is the outer peripheral surface of the housing.

Of course, the electrically controlled mounting portion may also be formed by a portion of the outer surface of an end plate of the housing, which may be a top plate or a bottom plate of the housing.

In order to make the technical solution of the present application easier to understand, the technical solution of the present application will be further described below by taking the example that the width direction of the electric control board 201 coincides with the up-down direction, the length direction of the electric control board 201 coincides with the left-right direction, and the thickness direction of the electric control board 201 coincides with the front-rear direction. Wherein the up-down direction and the left-right direction are perpendicular to each of the up-down direction and the left-right direction as shown in fig. 1 and 2.

For example, the casing 1 has a front side plate, a part of an outer side surface of the front side plate (front side surface of the casing 1) forms an electric control mounting portion, the via hole 102 is provided on an upper side of the front side plate, and the via hole 102 is located above the electric control plate 201. The cover 202 has a rearward opening, and the rear end surface of the cover 202 is fitted to the casing 1 so that an electric control installation space is defined between the cover 202 and the casing 1, and the electric control board 201 is located between the front side surface of the cover and the front side plate in the front-rear direction.

In some embodiments, the outer end aperture of the via 102 is disposed within the electrically controlled mounting space.

In some embodiments, as shown in fig. 2, the housing assembly further includes a base 203, the base 203 is disposed in the electric control installation space, the base 203 is disposed on the housing 1, and the electric control board 201 is disposed on the base 203.

For example, as shown in fig. 2, the rear surface of the base 203 is connected to the cabinet 1, and the rear surface of the electronic control board 201 is provided on the front surface of the base 203.

Therefore, when the whole machine is assembled, the electric control plate 201 can be fixed on the seat 203, the electric control plate 201 is supported by the seat 203, and then the seat 203 provided with the electric control plate 201 is fixed on the machine shell 1, so that the electric control plate 201 is conveniently fixed on the machine shell 1, further the whole machine is conveniently assembled, and the production efficiency of the whole machine is improved.

The base 203 is part of the electronic control unit 2 of the housing unit.

Optionally, the base is an insulating base, so that insulation between the electric control board and the casing is realized by using the base.

Alternatively, the base 203 is plate-shaped as a whole so that the wires passing through the wire holes 102 are electrically connected with the electronic control board 201.

In some embodiments, as shown in fig. 3 to 5, the casing 1 includes a casing plate 1011, the casing plate 1011 having a boss 1012 on an outer surface thereof, the boss 1012 being configured as a hollow boss having an inner cavity with a socket 1013 communicating with an outside of the casing plate 1011. The base 203 has a positioning protrusion 2034 thereon, and the positioning protrusion 2034 passes through the socket 1013 and is inserted into the cavity.

As will be appreciated by those skilled in the art, when the base 203 is mounted to the housing 1, the locating boss 2034 of the base 203 is inserted into the cavity through the socket 1013 to effect a pre-positioning of the base 203 on the housing 1. After the positioning protrusion 2034 and the protrusion 1012 are utilized to realize the pre-positioning of the base 203 on the casing 1, the reliable connection between the base 203 and the casing 1 can be ensured under the condition of using fewer fasteners, so that the number of fasteners is reduced, the assembly efficiency of the indoor air conditioner 100 is further improved, and the production cost of the indoor air conditioner 100 is reduced. The fastening piece can be all screws or all buckling pieces, or one part of the fastening piece is a screw, and the other part of the fastening piece is a buckling piece.

Thus, the processing of the casing 1 is facilitated, the production efficiency of the casing 1 is improved, and the production cost of the air conditioner indoor unit 100 is further reduced.

In some embodiments, the socket 1013 is formed at a connection of the outer peripheral edge of the boss 1011 with the housing plate 1011.

Therefore, the positioning protrusion 2034 of the base 203 can be inserted into the inner cavity deeper, and positioning reliability between the positioning protrusion 2034 and the casing 1 is increased, so that the base 203 is further convenient to be mounted on the casing 1, which is beneficial to further improving assembly efficiency of the air conditioner indoor unit 100 and reducing production cost of the air conditioner indoor unit 100.

Further, as shown in fig. 3, a socket 1013 is formed at a junction of a lower portion of the outer peripheral edge and the housing plate 1011 such that the socket 1013 is provided downward.

In the use process of the indoor unit 100, when the base 203 is in fire, the flame retardant in a molten state cannot be dripped into the casing 1 through the socket 1013 and the inner cavity, so that the flame retardant is prevented from contacting with inflammable materials in the casing 1, and the risk of igniting the inflammable materials in the casing 1 is reduced.

In addition, when the housing 203 and the casing 1 are assembled, the casing 1 is turned upside down (the top of the casing 1 is down and the bottom of the casing 1 is up), and the socket 1013 is provided upward. When the positioning protrusion 2034 of the base 203 is inserted into the inner cavity through the insertion opening, the wall surface of the protrusion 1012 can be hooked with the positioning protrusion 2034 to hang the base 203 on the casing, and when an assembler performs the fixed connection of the base 203 and the casing through the fastening piece, the assembler can fix the fastening piece by two hands without lifting the base 203, thereby further facilitating the installation of the base 203 on the casing, being beneficial to further improving the assembly efficiency of the air-conditioning indoor unit 100 and reducing the production cost of the air-conditioning indoor unit 100.
