[0031] like Figure 1-6 As shown, according to an embodiment of the first aspect of the utility model, a range hood with a water-electricity separation arrangement includes a shell 100, an electric control component 200, a cleaning component 300 and a box body component 400, the electric control component 200 is arranged in the shell 100, the electric control component 200 is used to be connected to the range hood electrical load, the cleaning component 300 is arranged in the shell 100, the cleaning component 300 at least includes a liquid pump, the box body component 400 is arranged in the shell 100, a first chamber 440 and a second chamber 450 separated from each other are arranged in the box body component 400, the electric control component 200 is located in the first chamber 440, the liquid pump is located in the second chamber 450, the box body component 400 is provided with a threading hole 140 respectively connecting the first chamber 440 and the second chamber 450, the electric control component 200 is connected to the liquid pump via a wire passed through the threading hole 140.
[0032] Among them, the shell 100 can choose a suitable shape according to the models of different range hoods. A smoke extraction port is arranged at the bottom of the shell 100, a fan is arranged inside the shell 100, and an electrical load such as a control panel is arranged at the bottom of the shell 100. In addition, an air duct can be connected to the top of the shell 100, one end of the air duct is connected to the fan, and the other end of the air duct is used to discharge the oil smoke to the outside.
[0033] The electric control component 200 may include a control circuit board, on which a processing chip such as an MCU or a CPU and its associated circuits are disposed. In addition, the control circuit board is also provided with a drive circuit for controlling various electrical devices.
[0034] In addition to the liquid pump, the cleaning component 300 generally also includes a liquid storage tank and a nozzle. The nozzle is located in the shell 100, and the liquid pump is connected to the liquid storage tank and the nozzle through pipes. The liquid pump can draw cleaning liquid from the liquid storage tank and spray it through the nozzle, thereby cleaning the inside of the shell 100. During the operation of the liquid pump, there may be a risk of water leakage at the connection point between the liquid pump and the pipe.
[0035] The utility model range hood utilizes the box body assembly 400 to separate a first chamber 440 and a second chamber 450 which are independent of each other on the shell 100; the electric control assembly 200 is located in the first chamber 440, and the liquid pump is located in the second chamber 450; the wires respectively connected to the electric control assembly 200 and the liquid pump pass through the threading hole 140; the electric control assembly 200 and the liquid pump can be close to each other, and the wiring is simple; since the first chamber 440 and the second chamber 450 are separated, even if water leakage occurs at the position of the liquid pump, it is not easy to affect the electric control assembly 200; the design has a compact structure, water and electricity separation, and a reasonable layout.
[0036] In some embodiments of the present invention, Figure 1 , Figure 2 As shown, the top of the shell 100 has a bearing end surface 110, and the box body assembly 400 includes a cover body 410 and a partition plate 420, the cover body 410 is covered on the bearing end surface 110, the partition plate 420 is arranged in the cover body 410 and the partition plate 420 is vertically arranged on the bearing end surface 110 to separate the first chamber 440 and the second chamber 450, and the threading hole 140 is opened on the partition plate 420.
[0037] The electronic control component 200 and the liquid pump can be placed outside the shell 100 to prevent the oil smoke from affecting the electronic control component 200 and the liquid pump when passing through the inside of the shell 100. The cover body 410 is covered on the electronic control component 200 and the liquid pump, and cooperates with the outer wall of the shell 100 and the partition plate 420 to form a first chamber 440 and a second chamber 450.
[0038] The partition plate 420 is used to separate the electronic control component 200 and the liquid pump. The electronic control component 200 and the liquid pump can be close to each other in space, but water will not enter the first chamber 440 from the second chamber 450. The wiring between the electronic control component 200 and the liquid pump is simple and the structure is compact.
[0039] In some embodiments of the present invention, Figure 4 As shown, the bearing end surface 110 at the second chamber 450 is provided with a receiving groove 120 recessed in the bearing end surface 110 , and the liquid pump is disposed in the receiving groove 120 .
[0040] When the liquid pump leaks, the water will be retained in the receiving groove 120 due to gravity, and will not flow back onto the bearing end surface 110 , further reducing the risk of water infiltrating from the bearing end surface 110 into the first chamber 440 .
[0041] Specifically, the edge of the slot position on the bearing end surface 110 close to the receiving groove 120 is inclined, so as to facilitate guiding the leaked water to the receiving groove 120 .
[0042] In addition, a drainage port may be provided in the receiving groove 120 , so that water can flow into the housing 100 . During the cleaning process, the water is eventually drained from the bottom of the housing 100 .
[0043] In some embodiments of the present invention, Figure 6 As shown, a sealing strip 430 is disposed between the side wall of the partition plate 420 and the inner wall of the cover body 410 , and the sealing strip 430 abuts against the side wall of the partition plate 420 and the inner wall of the cover body 410 , respectively.
[0044] The sealing strip 430 may include a rubber strip or a resin strip. The sealing strip 430 can seal the gap between the side wall of the partition plate 420 and the inner wall of the cover body 410 , and can effectively prevent water from leaking into the first chamber 440 .
[0045] Specifically, Figure 6 As shown, the partition plate 420 is usually made of sheet metal and can be relatively thin in thickness. However, when the thickness of the partition plate 420 is thin, it is not easy to press against the sealing strip 430. Therefore, a folded edge portion 421 is provided at the edge where the partition plate 420 contacts the inner wall of the cover body 410, and the sealing strip 430 presses against the folded edge portion 421 to achieve contact with the side wall of the partition plate 420.
[0046] The folded edge portion 421 has a certain area, so that the sealing strip 430 can be pressed against the surface of the folded edge portion 421, changing the contact with the edge of the side wall of the partition plate 420 to the surface contact with the folded edge portion 421, and the sealing performance is better.
[0047] In some embodiments of the present invention, Figure 3 As shown, the electric control component 200 will generate heat during operation. If the electric control component 200 is sealed in a relatively closed environment, the electric control component 200 is easily damaged. Therefore, the cover body 410 is provided with a ventilation hole group 460 on the wall corresponding to the first chamber 440. Specifically, the ventilation hole group 460 can be provided on the side wall of the cover body 410, and the ventilation hole group 460 respectively connects the first chamber 440 and the outside. Specifically, the ventilation hole group 460 includes a plurality of ventilation micropores. The ventilation micropores with smaller apertures can prevent water or smoke from entering the first chamber 440, but can ensure heat dissipation and ventilation.
[0048] In some embodiments of the present invention, Figure 3 As shown, for the convenience of wiring, the diameter of the wire hole 140 can be relatively larger than the thickness of the wire. Therefore, the wire hole 140 is located in an area more than half of the height of the partition plate 420 relative to the bearing end surface 110. The wire hole 140 is set at a relatively high position, and water is not easy to splash into the first chamber 440, thereby ensuring the stable operation of the electronic control component 200.
[0049] In some embodiments of the present invention, Figure 4 As shown, the bearing end surface 110 at the second chamber 450 is provided with a wiring opening 130 , and a water-blocking sheath 500 is passed through the wiring opening 130 , and the water-blocking sheath 500 presses against the outer wall of the wire or pipe passing through the wiring opening 130 .
[0050] The wiring opening 130 can pass wires or pipes, and the water-blocking sheath 500 can prevent excessive water in the second chamber 450 from leaking into the housing 100. The water-blocking sheath 500 can be made of rubber or resin material.
[0051] In some embodiments of the utility model, the water-retaining sheath 500 is annular, and the inner wall of the water-retaining sheath 500 is in close contact with the outer wall of the wire or pipe passing through the wiring opening 130. Generally speaking, the wiring opening 130 is circular, and the water-retaining sheath 500 can also be circular. The water-retaining sheath 500 is sleeved in the wiring opening 130, and the inner wall of the water-retaining sheath 500 is in close contact with the outer wall of the wire or pipe, thereby reducing the gap at the wiring opening 130, and water is not easy to enter the shell 100 from the second chamber 450.
[0052] In some embodiments of the present invention, Figure 5 As shown, the water retaining jacket 500 is annular, and a plurality of elastic ribs 510 are sequentially arranged on the inner wall of the water retaining jacket 500 along the annular direction. Adjacent elastic ribs 510 are closely attached to each other, and the elastic ribs 510 are separated from each other when force is applied.
[0053] When the wires or pipes pass through the through hole in the middle of the water-blocking sheath 500, they will be pressed against the elastic ribs 510, causing the stressed elastic ribs 510 to deform and the adjacent elastic ribs 510 to separate from each other, thereby allowing the wires or pipes to pass through. At the same time, they can also be tightly attached to the outer wall of the wires or pipes. After the wires or pipes are pulled out, the elastic ribs 510 restore their deformation, thereby making the adjacent elastic ribs 510 tightly attached to each other, effectively preventing water from entering the shell 100 from the second chamber 450.
[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
