Detailed Description

The following description of the specific embodiments of the present utility model is further provided with reference to the accompanying drawings, so that the technical scheme and the beneficial effects of the present utility model are more clear and definite. The embodiments described below are exemplary by referring to the drawings for the purpose of illustrating the utility model and are not to be construed as limiting the utility model.

Additional aspects and advantages of the utility model will be set forth in part in the description which follows, or may be learned by practice of the utility model.

Referring to fig. 1 and 2, the range hood comprises a hood body 1, and an oil screen 2, a water pump 3, a water box 4 and a refrigerating module 5 which are arranged on the hood body 1, wherein the oil screen 2 comprises a water diversion tank 2-1, a water collection tank 2-2 and a plurality of condensation sheets 2-3 connected between the water diversion tank 2-1 and the water collection tank 2-2, the water box 4 is connected with the water diversion tank 2-1 through an oil screen water inlet pipeline 6 and is connected with the water collection tank 2-2 through an oil screen water outlet pipeline 7, the water pump 3 is arranged on the oil screen water inlet pipeline 6, and the refrigerating module 5 is used for refrigerating the water box 4.

When the range hood is in operation, the range hood sucks in the oil smoke, and when the oil smoke passes through the condensing sheet 2-3, the oil smoke is condensed and attached to the condensing sheet 2-3 because the temperature of the condensing sheet 2-3 is lower than that of the oil smoke. After a period of continuous operation, the temperature of the condensing sheet 2-3 rises and the condensing effect becomes poor; at this time, the refrigerating module 5 and the water pump 3 are started at the same time, and the water in the water box 4 is cooled and transported to the water diversion channel 2-1; the water flows out of the water diversion channel 2-1 and flows into the water collection channel 2-2 along the surface of the condensation piece 2-3 under the diversion effect of the condensation piece 2-3, and the water flow covers the condensation piece 2-3 to exchange heat, so that the temperature of the condensation piece 2-3 is reduced, and the oil smoke condensation effect is improved; meanwhile, oil drops on the condensation piece 2-3 are flushed to the water collecting tank 2-2, so that frequent cleaning of the condensation piece 2-3 is avoided.

The water and oil in the water collecting tank 2-2 flow into the water box 4, oil drops in the water box 4 float on the upper layer, and the water pump 3 extracts liquid from the lower layer of the water box 4 to perform reciprocating circulation. When the water pump 3 is operated for a period of time, the temperature of the condensation plate 2-3 is reduced, the water pump 3 and the refrigerating module 5 stop operating, and all the liquid on the condensation plate 2-3 flows to the water collecting tank 2-2 and the water box 4. Because the heat conductivity of water is far lower than that of metal, and the water pump 3 and the refrigerating module 5 are not in operation, the oil smoke contacts with the metal condensing sheet, so that the condensing efficiency is greatly improved. The user can regularly take out water box 4 and handle greasy dirt and trade water, guarantees the oil smoke condensation efficiency of system.

In this embodiment, the condensation plate 2-3 is preferably made of copper, which has high thermal conductivity and is not deformed due to high temperature. Preferably, the refrigeration module is attached to the water box 4. The refrigeration module 5 may be of various constructions known in the art or that can be implemented in the future. When the smoke machine main motor works, after the smoke machine main motor works for 5-10 min, the water pump works for 10-20 s to cool circulating water, the refrigerating module is started after cooling is finished, the water in the water box is cooled for 1-3 min, and the circulation is repeated.

Referring to fig. 3 and 4, the water diversion channel 2-1 is connected to the upper end of the condensation plate 2-3, the water collection channel 2-2 is connected to the lower end of the condensation plate 2-3, and the water in the water diversion channel 2-1 flows into the water collection channel 2-2 along the condensation plate 2-3 under the action of self gravity. The section of the single condensing sheet 2-3 is arc-shaped, and the outer arc surface of the condensing sheet 2-3 faces the lampblack. The condensation sheets 2-3 are arranged in two rows in total, and the first row of condensation sheets and the second row of condensation sheets are arranged in a front-back staggered way.

During operation, the oil smoke passing through the gap of the first-row condensing sheet is blown to the cambered surface of the second-row condensing sheet to perform secondary condensation on the oil smoke, so that the oil smoke can be completely condensed. When the oil smoke enters from the front of the oil screen, the oil smoke has the largest oil smoke contact area with the condensing sheet 2-3; the oil smoke blocked and changed in direction by the second condensation piece can contact with the cambered surface on the back side of the first condensation piece, so that the oil smoke condensation effect with the best and maximum efficiency can be achieved.

Referring to fig. 5, openings 8 corresponding to the front and rear sides of each of the condensation sheets 2-3 are provided in both the water diversion tank 2-1 and the water collection tank 2-2, and water flows through the openings in the water diversion tank 2-1 along the condensation sheets 2-3 and then enters the water collection tank 2-2 through the openings in the water collection tank 2-2.

In this embodiment, the opening is preferably an arc-shaped opening that is oriented in line with the surface of the condensation plate 2-3. Obviously, the cross-sectional shape of the condensing sheet 2-3 can be changed appropriately according to actual needs, such as changing to an elliptic arc shape, a polygonal shape, etc., and correspondingly, the shape of the opening can also be changed appropriately. In addition, the arrangement of the rows of the condensing sheets 2-3 is not limited to the two rows, and the person skilled in the art may arrange three rows, four rows, even more rows or irregular arrangement according to the actual needs, and is not limited to the present embodiment.

Compared with the prior art, the range hood provided by the embodiment has the following characteristics: 1) The condensing sheet is washed by water, so that the greasy dirt can be taken away from the oil net, and the adhesion of the greasy dirt on the surface and the influence on the condensation of the lampblack are avoided. 2) The refrigeration system is used for cooling by using water, so that the oil net is ensured to filter oil smoke efficiently. 3) The water in this embodiment does not always cover the surface of the condensation plate, but is periodically started, so that most of the oil smoke contacts the condensation plate (high heat conductivity) instead of the surface water film (low heat conductivity), and the condensation efficiency of the oil smoke is ensured.
