[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "contacted", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] At present, the existing integrated cabinet air conditioner electrical box is installed on the inner side of the front panel, and because the power line and the communication line are connected to the wiring terminal of the electrical box through the front panel, if the electrical box needs to be repaired after sales, it is necessary to disconnect the power line and the communication line first, then remove the front panel, and then reconnect the power line and the communication line to the wiring terminal to repair the electrical box circuit, which makes after-sales maintenance complicated and difficult to operate. The present invention adopts a retractable arrangement of the electrical box on the cabinet, which can facilitate the staff to repair the electrical box, and in the process of maintenance, the circuit can be automatically disconnected, which can avoid the hidden danger of electric shock to the maintenance personnel.

[0051] To further illustrate the technical solution of the present invention, Figure 1 -As shown in the figure, the following specific embodiments are provided.

[0052] Embodiment 1:

[0053] The present application embodiment provides a Figure 1 The cabinet air conditioner shown includes a cabinet 1 and an electrical box assembly 2 arranged on the cabinet 1. A cavity is formed inside the cabinet 1. The electrical box assembly 2 includes a box body 211 and an electrical component 212 arranged in the box body 211. The box body 211 can be movably connected to the inner wall of the cavity of the cabinet 1 by being retractable from the outside of the cabinet. Specifically, the box body 211 is retractably arranged at a position close to the top of the cabinet 1. By retractably arranging the electrical box assembly 2 on the cabinet 1, it is convenient for the staff to repair the electrical box assembly 2, and the electrical box assembly 2 can be inspected and repaired without disassembling the cabinet 1.

[0054] Specifically, the box body 211 has a base 2111 and a first limiting plate 2112 and a second limiting plate 2113 formed on the base 2111. Figure 1 As shown, the second limiting plate 2113 and the first limiting plate 2112 are formed on the front and rear sides of the base 2111. Preferably, the base 2111, the first limiting plate 2112 and the second limiting plate 2113 are integrally formed to present a U-shaped box body, and the electrical component 212 is located inside the box body.

[0055] A positioning portion 111 is formed on the inner wall of the cavity of the cabinet 1. Figure 4 As shown, when the electrical box assembly 2 is pulled outward, the first limit plate 2112 contacts the positioning portion 111 so that the first limit plate 2112 and the positioning portion 111 are pressed against each other. At this time, the electrical box assembly 2 is in the first limit position, as shown in FIG. Figure 5 As shown, when the electrical box assembly 2 is pushed into the cavity, the second limit plate 2113 abuts against the positioning portion 111 to place the electrical box assembly 2 in the second extreme position; when the electrical box assembly 2 is in the first extreme position, the electrical box assembly 2 is placed outside the cabinet 1, and the electrical box assembly 2 can be inspected; when the electrical box assembly 2 is in the second extreme position, the electrical box assembly 2 is placed inside the cabinet 1, and the electrical box assembly 2 is placed inside the cabinet 1 to work.

[0056] Furthermore, in order to improve the safety of the staff when repairing the motor box assembly 2, the cabinet air conditioner also includes a switchable component 3 linked with the electrical box assembly 2, and the switchable component is used to control the switching of the high-voltage power of the electrical box. When the electrical box assembly 2 is in the first extreme position, the switchable component 3 can disconnect the high-voltage circuit. At this time, the high-voltage circuit is disconnected, which improves the safety during detection; when the electrical box assembly 2 is in the second extreme position, the switchable component 3 can connect the high-voltage circuit. At this time, the electrical box assembly 2 is placed in the cabinet and starts to operate.

[0057] In this embodiment, by arranging a switchable component 3 on the cabinet 1, the safety of the staff when detecting the electrical box assembly 2 can be improved. That is, by arranging the switchable component 3, the on and off of the circuit can be automatically determined by the travel of the electrical box assembly 2, thereby avoiding the risk of electric shock for maintenance personnel.

[0058] In order to more intuitively understand the content of the present invention, the components of the cabinet 1 are specifically described below:

[0059] like Figure 1-Figure 3 As shown, the cabinet 1 mentioned above includes a front panel 11, and a first opening is provided on the front panel 11. The electrical box assembly 2 is arranged in the cavity so as to be drawable from the first opening.

[0060] Specifically, Figure 1 As shown, the cavity is provided with relative side walls extending along the front-to-back direction of the cabinet 1, and guide rails 16 are formed on the two relative side walls. The electrical box assembly 2 is placed on the guide rails 16, and the guide rails 16 are configured to slide the electrical box assembly 2 along the guide rails 16, wherein the positioning portion 111 is a bent edge of an upper panel formed on the top wall of the cavity.

[0061] It is worth noting that the cavity mentioned above can be formed in a variety of ways. For example, the cavity can be directly formed by the external panel of the cabinet 1. For another example, a cavity for accommodating a power supply box assembly can be formed by separately arranging a plurality of panels inside the cabinet. The specific formation method of the cavity is not limited in this embodiment. For the convenience of explanation, the following specific explanation is given by taking the case where the cavity is directly formed by the external panel of the cabinet 1 as an example. Specifically, the cabinet 1 also includes a rear panel 12, an upper panel 13, a lower panel 14 and symmetrically arranged side panels 15. The front panel 11, the rear panel 12, the upper panel 13, the lower panel 14 and the side panels 15 are spliced ​​and combined to form a cabinet 1 with a first opening at the front and a cavity inside, wherein the first opening is located at the front panel 11 (i.e., the front of the cabinet 1), and the electrical box assembly 2 is pullable and arranged at the first opening. When the cavity is directly formed by the external panel of the cabinet 1, as Figure 1 As shown, at this time, the two guide rails 16 are directly formed on the two corresponding side panels 15 .

[0062] When the electrical box assembly 2 slides outward or inward along the guide rail 16, it can move to the first limit position and the second limit position mentioned above. It is worth noting that in some alternative embodiments, the electrical box assembly 2 can also be pulled out by means of a slide rail or a slideway, that is, a slide rail is set on the side wall of the electrical box assembly 2, and a slideway is set on the inner wall of the cabinet 1, and the electrical box assembly 2 can also be pulled out. In this embodiment, the specific pulling and pulling structure of the electrical box assembly 2 is not limited, as long as the pulling and pulling function of the electrical box assembly 2 can be realized. For the convenience of explanation, the following is a specific explanation taking the sliding of the electrical box assembly 2 on the guide rail 16 as an example.

[0063] like Figure 4 As shown, when the electrical box assembly 2 moves to the first extreme position, the upper edge of the first limiting plate 2112 presses against a surface on the bent edge of the upper panel.

[0064] like Figure 5 As shown, when the electrical box assembly 2 moves to the second extreme position, the upper edge of the second limiting plate 2113 presses against the other surface of the bent edge of the upper panel.

[0065] More specifically, the on-off component 3 is arranged at the positioning portion 111 on the cabinet 1. When the electrical box assembly 2 is pulled out, the second limit plate 2113 separates from the on-off component 3, and the circuit of the electrical box assembly 2 is disconnected. When the electrical box assembly 2 is pushed, the second limit plate 2113 contacts the on-off component 3, and the circuit of the electrical box assembly 2 is connected. Preferably, the on-off component 3 is a travel switch arranged at the bent edge of the upper panel, such as Figure 1 As shown, a slot is provided at the bent edge of the upper panel, and a travel switch is fixedly installed in the slot. The electrical component 212 includes a circuit breaker, and the travel switch controls the disconnection and connection of the circuit breaker, thereby controlling the disconnection and connection of the circuit.

[0066] When the unit is in normal working state, the electrical box assembly 2 is in the second extreme position, the front of the electrical box assembly 2 coincides with the bent edge of the upper panel and touches the travel switch, at this time, the circuit breaker in the electrical box assembly 2 for controlling the on and off of the strong current circuit is connected, and the unit operates normally; when the unit needs maintenance, the electrical box assembly 2 is pulled out to make the electrical box assembly 2 in the first extreme position, at this time, the bent edge of the upper panel coincides with the back of the electrical box assembly 2, and the circuit breaker in the electrical box assembly 2 for controlling the on and off of the strong current circuit is disconnected, thereby avoiding the hidden danger of electric shock to the maintenance personnel. It is worth noting that when the electrical box assembly 2 is in the first extreme position, if the maintenance personnel need to connect the strong current, they need to manually connect the circuit breaker to realize the strong current power-on.

[0067] In order to improve the stability of the electrical box assembly 2 during operation, the travel switch in this embodiment adopts a magnetic travel switch. When the electrical box assembly 2 is in the cabinet 1 (that is, the electrical box assembly 2 is in the second extreme position), the magnetism of the travel switch will suck and fix the electrical box assembly 2 and the bent edge of the upper panel, thereby avoiding the electrical box assembly 2 from being separated from the first extreme position when no external force is applied, causing the electrical box assembly 2 to be powered off, thereby improving the stability of the electrical box assembly 2 during operation.

[0068] The internal configuration of the cabinet 1 is described in detail below:

[0069] like Figure 4-Figure 6 As shown, the cabinet air conditioner is an integrated cabinet air conditioner, and a partition 4 is fixedly arranged inside the cabinet body 1. The partition 4 has a vertical section and an inclined section. The vertical section and the inclined section form a plate similar to an L-shape. The partition 4 divides the interior of the cabinet body 1 into an evaporation area 17 and a condensation area 18. The electrical box assembly 2 is in the evaporation area 17. When the electrical box assembly 2 is in the second extreme position, the rear part of the electrical box assembly 2 (i.e., the first limit plate 2112) is in contact with the vertical section of the partition 4.

[0070] An internal fan 171 and an evaporator 172 are provided in the evaporation area 17 of the cabinet 1, wherein the internal fan 171 and the evaporator 172 are located below the electrical box assembly 2, and the areas corresponding to the evaporator 172 and the internal fan 171 on the front panel 11 are respectively provided with a first air outlet and a first air inlet. When the internal fan 171 and the evaporator 172 are working, the ambient air passes through the first air inlet, the evaporator 172 and the internal fan 171 in sequence and is discharged from the first air outlet at the internal fan 171 to form a An internal air duct (i.e., a heat dissipation duct) is used for dissipating heat from the electrical box assembly 2. The internal fan 171 and the evaporator 172 cooperate with each other to perform air cooling and heat dissipation on the electrical box assembly 2 in the evaporation area 17. An external fan 181, a compressor 182 and a condenser 183 are provided in the condensation area 18. The compressor 182, the condenser 183 and the evaporator 172 are connected by a refrigerant pipeline. When the unit is running, the heat of the electrical box assembly 2 is dissipated by the internal fan 171 and the evaporator 172.

[0071] In order to improve the heat dissipation effect of the electrical box assembly 2, in this embodiment, a radiator 213 is arranged at the bottom of the electrical box assembly 2, and the radiator 213 has heat dissipation ribs, wherein the heat dissipation ribs are arranged parallel to the bottom of the electrical box assembly 2. When the unit is running, the radiator 213 is in the evaporation area 17, and the radiator 213 is configured to dissipate heat for the electrical box assembly 2, such as Figure 6 As shown, when the internal fan 171 cools the radiator 213, the air flow direction is parallel to the longitudinal direction of the fins (eg Figure 6 As shown in the direction of the arrow in the figure), the heat dissipation efficiency of the radiator 213 is improved.

[0072] Further, the specific dimensions of the radiator 213 are described as follows: Figure 1 As shown, the width of the radiator 213 is the same as the width of the electrical box assembly 2, and its width is L1. The top of the front panel 11 has a notch that can accommodate the radiator 213. The length of the radiator 213 is the same as the length of the notch on the front panel 11, and its length is L2. The height of the radiator 213 is the same as the height of the notch in the front panel 11, and its height is L3. When the electrical box assembly 2 moves along the guide rail 16, the left side, right side, and bottom surface of the radiator 213 are tightly matched with the groove on the front panel 15, and the bottom surface of the electrical box assembly 2 is tightly matched with the upper edge of the front panel 11, thereby preventing the moist and cold air in the evaporation area 17 from leaking out and exchanging heat with the electrical components 212 in the electrical box assembly 2, thereby avoiding the generation of condensation water on the surface of the electrical components 212 to cause safety hazards.

[0073] Further, such as Figure 1 As shown, a windshield assembly 214 is also provided on the electrical box assembly 2. The windshield assembly 214 is in contact with the inner wall surface of the cabinet 1 to prevent the damp and cold air blown out by the internal fan 171 from entering the interior of the electrical box assembly 2. Specifically, the windshield assembly is a sponge filler or a damping sealing structure connected to the bottom, left, right and back of the electrical box assembly 2. Preferably, the windshield assembly is a sponge filler. By providing the windshield assembly 214 on the electrical box assembly 2, the inner side of the electrical box assembly 2 can be separated from the inner air duct in the evaporation area 17, so that no matter where the electrical box assembly 2 moves to, there will be no air leakage around the electrical box assembly 2, thereby further preventing the damp and cold air generated in the inner air duct from entering the interior of the electrical box assembly 2 and exchanging heat with the electrical components 212, thereby improving the stability of the electrical box assembly 2 during operation.

[0074] In order to seal the first opening on the cabinet 1 and the notch on the front panel 11, a sealing plate 214 is fixedly connected to the bottom of the electrical box assembly 2. When the electrical box assembly 2 and the radiator 213 are placed in the cabinet 1, the sealing plate 214 covers the first opening on the cabinet 1 and the notch on the front panel 11 to achieve sealing of the first opening and the notch.

[0075] It is worth noting that, in the present embodiment, a second opening connected to the condensation area 18 is further provided at the rear portion of the cabinet 1, wherein the condenser 183 is arranged at the second opening. Combined with the first opening on the cabinet 1 mentioned above, it can be seen that the front panel 11 in the present embodiment does not cover the electrical box assembly 2, thereby reducing the height of the front panel 11; the rear panel 12 does not cover the condenser 183, thereby reducing the height of the rear panel, and the honeycomb structure corresponding to the condenser 183 is also cancelled on the rear panel 12, thereby reducing production costs and improving production efficiency.

[0076] In addition, in order to prevent the wires from being pulled when the electrical box assembly 2 is pulled out, the wiring path of the electrical box assembly 2 is set as follows.

[0077] Before introducing the wiring path of the electrical box assembly 2 , it is necessary to explain the distribution of the wires of the electrical box assembly 2 : strong wires and weak wires for conducting the electrical components 212 are connected to the bottom of the electrical box assembly 2 .

[0078] In order to prevent the wires from being pulled when the electrical box assembly 2 is pulled out, Figure 4-Figure 6 As shown, a strong wire trough 19 and a weak wire trough 20 are symmetrically arranged on two opposite side walls extending in the front-rear direction of the cabinet 1. In this embodiment, the strong wire trough 19 and the weak wire trough 20 are symmetrically arranged on the inner wall of one side opposite to the two side panels 15, wherein the strong wire trough 19 is arranged close to the strong wire, and the weak wire trough 20 is arranged close to the weak wire. The strong wire is routed along the strong wire trough 19, and the weak wire is routed along the weak wire trough 20. Specifically, the outlet position of the strong and weak wire troughs is located at the center position of the width of the electrical box assembly 2, and the distance from the center line of the strong and weak wire troughs to the front panel 11 is L / 2, and the center of the strong and weak wire ports of the electrical box assembly 2 is located at the bottom of the electrical box assembly 2 and close to the rear of the electrical box assembly 2. The design of this position makes it possible for the wiring harness lengths of the strong and weak wire troughs and the strong and weak wire inlets of the electrical box assembly 2 to be equal and longest when the electrical box assembly 2 is in the second extreme position and the first extreme position. The longest wiring length is reserved when designing the wiring, so the wires will not be pulled when the electrical box assembly 2 moves forward and backward. In addition, by separating the strong and weak wires for routing, the conducted radiation can be reduced and the electromagnetic compatibility can be improved.

[0079] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
