Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular relates to a vertically installed anti-condensation water electric heating junction box structure. Background Technology

[0002] Electric heating junction boxes are generally installed on the air conditioning unit panel. Conventional electric heating junction boxes on the market are often horizontally installed with the electric heating cable outlet above the terminal block. Although this structure is simpler to operate, cold air leakage is inevitable at the contact point between the air conditioning unit and the junction box. This causes the temperature inside the junction box to drop, and the temperature difference between the inside and outside produces condensation. Especially at the connection point, where the connection wire is above the terminal block, condensation can enter the terminal block along the connection wire, which can easily cause short circuits or even serious accidents such as fires. Therefore, for continuous, long-term, and reliable operation, it is imperative to develop a vertically installed anti-condensation electric heating junction box structure. Utility Model Content

[0031] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-5 As shown, a vertically installed anti-condensation electric heating junction box structure includes a box body 1 and a door cover 2. One side wall of the door cover 2 is connected to the box body 1 by a hinge 5, allowing the door cover 2 to rotate relative to the box body 1. The box body 1 is provided with a fixed guide rail 3 and several knockout holes 8. The fixed guide rail 3 is used to fix the terminal block 7, and the connecting wire 6 passes through the knockout holes 8 into the box body 1. The knockout holes 8 can be flexibly selected according to the number of electric heating segments, increasing its versatility. The fixed guide rail is set along the length direction of the box body 1, and the knockout holes 8 are located on one side of the fixed guide rail. The box body 1 is installed perpendicular to the ground in the length direction.

[0033] Insulation cotton 4 is provided on the back side wall of the box 1 to prevent the cold air from the air conditioner from entering the junction box and reduce the possibility of condensation.

[0034] The top of the box 1 is provided with a baffle plate 9, which is inclined toward the door cover 2. The baffle plate is made of ABS material to prevent condensation from dripping onto the terminal block 7 and to prevent condensation from forming on itself.

[0035] Furthermore, the door cover 2 is provided with absorbent cotton 13 on the side wall near the box body 1. The bottom of the slope of the baffle plate 9 is above the absorbent cotton 13. The baffle plate 9 is provided with a water drop groove at one end. The absorbent cotton 13 is provided with a water-proof layer 14, which is made of plastic and is attached to the absorbent cotton 13. After the water droplets blocked by the baffle plate 9 converge, they flow along the baffle plate 9 and fall from the water drop groove. The absorbent cotton 13 absorbs the water flow. Under the action of gravity, the water flow flows along the absorbent cotton 13 to the bottom of the box body 1, preventing the water droplets left on the baffle plate 9 from contacting the terminal block 7.

[0036] The bottom of the box body 1 and the door cover are provided with several water passage holes 15. The diameter of the water passage holes 15 is 6mm. The bottom of the box body 1 is provided with an inclined surface facing the water passage holes 15. The water flowing to the bottom of the box body 1 flows along the inclined surface of the bottom of the box body 1 towards the water passage holes 15, and the water in the box body 1 is discharged through the water passage holes 15.

[0037] The side wall of the housing 1 is provided with multiple protrusions 16. The protrusions 16 are located between the knockout holes 8 and the fixed guide rail. Each knockout hole 8 has at least one protrusion 16 on one side. The protrusions 16 are located below the corresponding knockout holes 8. When the connecting wire 6 passes through the knockout holes 8 and is connected to the terminal block 7, it is wrapped around the protrusions 16, so that a recess is formed on the connecting wire 6 to prevent condensate from flowing along the wire to the terminal block 7.

[0038] The door cover 2 is equipped with a rotary latch lock 10, which includes a lock handle 11 and a lock tongue 12. The lock handle 11 and the lock tongue 12 are connected. The side wall of the box body 1 is provided with a connecting part that cooperates with the lock tongue 12. The lock handle 11 is turned into the vertical state as open and turned into the horizontal state as closed. The rotatable lock handle 11 and the lock tongue 12 are linked together. When the lock tongue 12 abuts against the connecting part, it can fix the door cover 2.

[0039] The rotary latch 10 has a keyhole to prevent accidental opening and contact, thus increasing security.

[0040] During installation, select the corresponding number of knockout holes 8 according to the number of electric heating segments. The electric heating junction box is fixed to the outer panel of the air conditioning unit with self-tapping screws. A conduit is provided between the outer panel and the box body 1. Select the appropriate terminal block 7 according to the current of each electric heating segment and install it onto the fixed guide rail. The connecting wire 6 passes through the conduit and is fixed to the terminal block 7. The connecting wire 6 has a recessed area through the protruding rod 16. Fill the gap in the conduit with sealant. After closing the door cover 2, turn the lock handle 11 to make it horizontal. At this time, the lock tongue 12 presses against the box body 1. Finally, remove the key to complete the installation. When the customer is wiring, insert the key and turn the lock handle 11 to make it vertical. The door cover 2 can then be opened. The customer's connecting wire 6 enters vertically upwards from the bottom of the box body 1 and connects to the terminal block 7, preventing condensate from flowing along the wire to the terminal block 7.

[0041] This application effectively prevents condensation. The back of the electric heating junction box is covered with insulation cotton 4, and the wire hole is filled with mud to prevent cold air from entering the box 1 and causing condensation. In fact, as the operating time goes by, or when the unit is installed outdoors, condensation will inevitably be generated in the electric heating junction box. The vertical installation structure, the recessed design of the connecting wire 6, and the addition of an ABS water baffle 9 at the top can effectively prevent condensation from entering the terminal block 7 and causing short circuits. The knock-out hole 8 on the back of the box 1 can be flexibly selected according to the number of electric heating sections, increasing its versatility. In addition, two 6mm diameter water passage holes 15 are opened at the bottom of the box 1 and the door cover 2 to drain condensation. The whole structure is simple to install, highly versatile, and safe.

Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
