Description

Technical Field

[0001] The utility model relates to the technical field of the structure of air-conditioning units, in particular to a transparent and visible waterproof electrical box. Background Art

[0002] With the development of data centers, computer room air conditioners that serve them have sprung up like mushrooms after a spring rain. The development of computer room air conditioners focuses on speed as well as comprehensive development, such as exquisite appearance, ergonomic structural design, and good electronic control servo system. In the case of compact space, in order to take into account the entire layout, the electrical box is sometimes placed under the evaporator. When operating in areas with high humidity and during special working conditions of proofing and testing, condensation appears on the inner wall of the unit, which will threaten the stability of the electrical box. Therefore, the electrical box is the hub of the electronic control system, and waterproofing is crucial in the entire unit. Conventional electrical box waterproofing uses sheet metal for mechanical shielding, rubber rings for wire anti-cutting treatment, and sheet metal parts are fixed by welding or riveting, so they need to be installed and disassembled separately, which takes up a lot of space. Utility Model Content

[0003] The utility model provides a transparent and visible waterproof electrical appliance box, which is used to solve the technical problems raised in the background technology.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A transparent and visible waterproof electrical box comprises a box body, wherein the box body is a hollow structure with an opening at one end, a detachable cover is installed at the opening, the cover is made of a transparent acrylic plate, the top of the box body is designed with a cut edge to form an inclined surface, and the edge of the cover plate close to the inclined surface is bent to form a folded edge; a plurality of threading holes are reserved at the top and bottom of the box body, and waterproof joints are installed at the threading holes.

[0006] As a further preferred embodiment of the present invention, the edge of the cover plate close to the inclined surface and the adjacent edge are bent outward to form a plurality of folded edges, and the adjacent folded edges are connected by arcs.

[0007] As a further preferred embodiment of the present invention, a plurality of mounting holes are provided on the folded edge, which is connected to the box body by bolt fixing.

[0008] As a further preferred embodiment of the present invention, a component group, a main control board and a wire trough are installed in the box; a horizontal middle partition is provided in the box, the component group is located above the middle partition, the main control board is located below the middle partition, the wire trough is arranged at the bottom of the box and located below the main control board; the main control board is electrically connected to the component group. A cavity is opened in the middle of the middle partition for accommodating the wiring harness.

[0009] As a further preferred embodiment of the present invention, the component group includes an air switch; the air switch is arranged to protrude from the surface of the box and needs to be operated frequently, and a corresponding position of the cover plate is provided with an avoidance hole for the air switch to pass through.

[0010] As a further preferred embodiment of the present invention, a plurality of U-shaped holes are provided at the edge of the cover plate. The box body 1 is a sheet metal part. After being bent for many times, the position of the mounting holes cannot achieve a high precision. Since the acrylic material is relatively brittle, when the box body and the cover plate are connected, it is easy to cause cracks if some mounting holes are fixed and then the remaining mounting holes are hard-tackled. Therefore, U-shaped holes are provided to allow fine-tuning according to the position of the mounting holes to avoid the scrapping of the cover plate and ensure the overall aesthetics.

[0011] The edge of the cover is provided with a plurality of U-shaped holes, which are movably connected to the box body by bolts. The position of the mounting holes of the bolts at the connection between the box body and the cover cannot be guaranteed. Since the acrylic cover is very brittle, it is impossible to fix the mounting holes and then perform hard tapping. Therefore, the U-shaped holes are opened, and fine-tuning can be performed according to the position of the mounting holes to ensure the overall beauty.

[0012] As a further optimization of the present invention, the depth of the box is 95 mm, which satisfies the requirement that the box be as shallow as possible except for the height of all components, thereby reducing the risk of water ingress.

[0013] As a further preferred embodiment of the present invention, the electrical box is installed inside the computer room air conditioner and is located below the evaporator, and the inclination angle of the slope is consistent with the inclination angle of the evaporator.

[0014] As a further preferred embodiment of the present invention, L-shaped brackets are provided on the top and bottom of the box body, one side of the L-shaped bracket is connected to the box body, and the other side is connected to the computer room air conditioner.

[0015] Compared with the prior art, the utility model has the following advantages or technical effects:

[0016] The top of the box is designed with a cut edge near the evaporator. The slope formed has a diversion effect. The condensation under the evaporator is diverted to the bottom of the air-conditioning unit along the inclination direction of the slope. This structure can effectively prevent condensation from entering the interior of the electrical box. The edge of the cover plate close to the slope is bent to form multiple folded edges. The arcs between adjacent folded edges prevent condensation from entering the electrical box from the gap between the cover plate and the box, further protecting the components in the electrical box. The threading hole on the top of the box uses a waterproof joint. The condensed water from the side door panel or evaporator enters from here. There is no risk of water ingress at the bottom. Therefore, the threading hole at the bottom can reduce costs and use rubber rings for anti-cutting treatment without the risk of water ingress. The cover plate is transparent and visible, and the air switch can be adjusted directly; U-shaped holes are opened around the cover plate, and the cover plate can be fine-tuned according to the position of the installation hole. The installation margin is appropriate and the installation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention are described below in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the protection scope of the present invention.

[0023] Please refer to the attached Figure 1-Figure 3 The electrical box is installed below the evaporator 15 in the machine room air conditioner through an L-shaped bracket 5. The electrical box includes a box body 1. The box body 1 is a hollow structure with an opening at one end. A removable cover 2 is installed at the opening. The cover 2 is made of a transparent acrylic plate. The top of the box body 1 near the evaporator adopts a cutting design to form an inclined surface. The inclined surface has a diversion function and can divert condensation to the bottom of the air-conditioning unit to prevent condensation from entering the electrical box. The edge a of the cover 2 close to the inclined surface and the adjacent edge b are bent outward to form a folded edge. The adjacent folded edges are connected by an arc without a gap, so condensation is prevented from entering the electrical box through the gap. By the attached Figure 1It can be seen that edge a and edge b are closest to the inclined surface, so they are most likely to get water in. Since acrylic is brittle, if all edges are folded, a slight installation error will easily cause the cover 2 to break. Therefore, only edge a and edge b, which are at greater risk of water ingress, are folded, which effectively prevents water from entering and avoids damage to the cover 2. Multiple threading holes are reserved on the top and bottom of the box 1. A waterproof joint is installed at the top threading hole. The condensed water from the side door panel or evaporator enters from the top threading hole. The bottom threading hole can reduce costs and can be treated with rubber rings for anti-cutting, without the risk of water ingress. Multiple mounting holes are provided on the folded edge for bolt fixation with the box 1.

[0024] The box 1 is equipped with a component group, a main control board 11 and a wire trough 12. A horizontal middle partition 13 is provided in the box 1, the component group is located above the middle partition 13, the main control board 11 is located below the middle partition 13, the wire trough 12 is arranged at the bottom of the box 1 and below the main control board 14, and the main control board 11 is electrically connected to the component group. Further explanation, the component group includes a transformer 6, an air switch 7, a relay 8, a switching power supply 9 and an AC contactor 10, the transformer 6 is installed on the top of the box 1, the relay 8, the switching power supply 9 and the AC contactor 10 are installed in the middle of the box 1 and close to the inclined side, the air switch 7 is arranged in the middle of the box 1 and away from the inclined side, the air switch 7 is protruding from the surface of the box 1 and needs to be operated frequently, the corresponding position of the cover plate 2 is provided with an avoidance hole 3 for the air switch 7 to pass through, and the edge of the cover plate 2 is provided with a plurality of U-shaped holes for bolting with the box 1. The depth of the box 1 is selected to be about 95 mm, which satisfies the requirement that the height of all components in the electrical box is as shallow as possible to reduce the risk of water ingress.

[0025] The assembly steps of the electrical box are as follows:

[0026] 1) Rivet nuts on the box to make it ready for installing components, and then fix the transformer, circuit breaker, control mainboard, switching power supply and other components in the box by means of guide rails or screws.

[0027] 2) Connect the box with installed components to two L-shaped brackets, one at the top and one at the bottom for uniform force. The bracket is used to connect the entire electrical box and the air conditioning unit frame to achieve a modular design of the electrical box.

[0028] 3) Connect all the components that need to be wired in the box and the external connection wires of the electrical box in sequence, and put the wiring harnesses in the wire slots, which is beautiful and convenient. The wiring harnesses coming out from the top pass through the waterproof connector and are fixed at the threading hole. The wiring harnesses coming out from the bottom can directly reduce the cost by putting on rubber rings, because the entire electrical box shields it and there is no risk of water ingress due to gravity.

[0029] 4) Place the two folded edges of the transparent visible acrylic cover on the box body with riveted nuts, fix it with bolts, and expose the open position for easy adjustment. At this point, the entire electrical box is assembled.

[0030] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
