The cabinet includes a chassis (12) and a collection cover (11). The collection cover ( 11) Fixed at the bottom of the chassis (12). The range hood device includes a first exhaust fan (21), an air pipe (22), an oil and gas separator (23), and an air collecting bucket (24). The first exhaust fan (21) is fixed at the bottom of the collection cover (11), and the first exhaust fan (21) is located inside the collection cover (11), and the air collecting bucket (24) is located inside the chassis (12), and The lower end of the air hopper (24) is communicated with the collecting cover (11), one end of the air pipe (22) is communicated with the upper end of the air collecting hopper (24), and the oil and gas separator (23) is arranged on the air pipe (22). The heat preservation device includes a heat preservation box (31), a second exhaust fan (32), and two heat exchange components. The heat preservation box (31) is hollow, the middle of the heat preservation box (31) is provided with a heat preservation frame (33), and the outside of the heat preservation box (31) is hinged with a cover (37) for sealing the heat preservation frame (33). The thermal insulation box (31) is fixed on the top of the cabinet (12), and the second exhaust fan (32) is fixed on the left side wall of the thermal insulation box (31). The two heat exchange parts are both arranged in the heat preservation box (31), and the two heat exchange parts are respectively located on the upper and lower sides of the heat preservation frame (33). The heat exchange components include two main pipes (34), multiple heat exchange tubes (35), and two connecting pipes (36). The multiple heat exchange tubes (35) are arranged in parallel, and the two connecting pipes (36) are respectively located in the heat exchange tube. Two ends of the tube (35), and the two connecting tubes (36) are respectively connected with the adjacent heat exchange tube (35) ports, and the two main pipes (34) are respectively connected with the two connecting tubes (36). One of the main pipes (34) of the upper heat exchange component is connected with the output end of the second exhaust fan (32), and the other main pipe (34) extends through the heat preservation box (31) to the outside. One of the main pipes (34) of the heat exchange component located below is connected with the other end of the air pipe (22), and the other main pipe (34) extends through the heat preservation box (31) to the outside.

When using the range hood, install the induction cooker in accordance with the ordinary range hood. When in use, start the first exhaust fan (21), the first exhaust fan (21) sucks away the oil fume generated on the stove, and transports it away through the air pipe (22) connected to the air collecting hopper (24), and the oil fume is discharged to When the oil and gas separator (23) is used, the oil in the oil fume will be separated and left behind. The remaining air with heat will continue to be transported along the air duct (22). The hot air is transported to the heat exchange components located below. Hot air enters a plurality of heat exchange tubes (35) from the main pipe (34). The heat preservation box (31) is filled with heat transfer oil, a plurality of heat exchange tubes (35) are provided, and the heat exchange tubes (35) are immersed in the heat transfer oil. Therefore, when hot air is introduced into the heat exchange tube (35), its heat is transferred to the heat transfer oil through the heat exchange tube (35), and the continuous heat transfer makes the heat transfer oil heat up. After the heat transfer oil heats up, it will transfer the heat to the heat preservation frame (33). Except for the side of the opening, the other sides of the heat preservation frame (33) are covered by the heat transfer oil, so the heat transfer oil can well transfer the heat to On the heat preservation frame (33), the temperature inside the heat preservation frame (33) is raised. The heat preservation frame (33) has a relatively large space, and the cooked food can be put into the heat preservation frame (33), and then the cover (37) is closed, and the food can be heated and kept warm. At the same time, the second exhaust fan (32) is activated to draw external air into the heat exchange component located above. The outside air enters the heat exchange part and exchanges heat with the heat transfer oil when passing through the heat exchange tube (35). Since the temperature of the heat transfer oil is higher than that of the outside air, the heat in the heat transfer oil is transferred to the air inside the heat exchange tube (35) through the heat exchange tube (35), and the heated air is then transferred from the main pipe at the other end ( 34) Exhaust from the cooker hood. In this way, the air in the kitchen is heated, so that in the cold winter, the temperature in the kitchen can be maintained at an adaptive temperature, which improves the comfort of the cook.

In an embodiment of the present invention, the input end of the second exhaust fan (32) is fixed with a screen (41), and the main pipe (34) extending to the outside is provided with a one-way valve (30). The screen (41) arranged at the input end of the second exhaust fan (32) can prevent large solid particles from entering the inside of the fan, thereby avoiding the influence of large solid particles on the internal components of the fan. The one-way valve (30) can prevent the gas from flowing back into the main pipe (34), thereby avoiding the influence of the gas backflow on the heat exchange components.

In an embodiment of the present invention, an oil storage tank (42) is fixed on the side wall of the cabinet (12), and the output end of the oil-air separator (23) is in communication with the oil storage tank (42). The oil storage tank (42) can receive the oil separated by the oil-air separator (23) to prevent the turbulent flow of grease from polluting the environment.

In an embodiment of the present invention, the heat preservation device further includes an electric heating plate (39), and the electric heating plate (39) is fixed to the bottom of the heat preservation frame (33). When the temperature of oil fume is not high enough to heat the food in the heat preservation frame (33), you can start the electric heating plate (39) to heat the air and the food in the heat preservation frame (33) so that the food can be kept in the heat preservation frame (33). The right temperature.

In an embodiment of the present invention, an LED lamp (43) is fixed at the bottom of the collection cover (11). In the case of poor lighting conditions, the cookware can be illuminated by turning on the LED light (43), which is convenient for the user to cook.
