[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 、 2, as shown in Figures 3 and 4, the present utility model provides a technical solution: a cross-border cabinet range hood, comprising: a housing 1, the housing 1 being a right-angled triangular cavity, and the inclined plane of the cavity being an open structure; a filter screen 5 is snap-fitted inside the housing 1, and a limit pin 16 for fixing the filter screen 5 is slidably installed on the outside of the housing 1; an air duct 2 is welded to the top of the housing 1, and an exhaust air duct 18 and a suction air duct 3 are provided inside the air duct 2, and the suction air duct 3 communicates with the inside of the housing 1; a cold air box 6 is placed at the end of the housing 1, a semiconductor refrigerating sheet 10 is embedded and installed on the top of the cold air box 6 and a fan 9 is installed inside it, a metal sheet 11 is fixedly connected to the air outlet position of the fan 9, the top of the metal sheet 11 is connected to the refrigerating end of the semiconductor refrigerating sheet 10, and a heat dissipation air duct 12 is installed at the heating end of the semiconductor refrigerating sheet 10, and the heat dissipation air duct 12 communicates with the suction air duct 3.

[0023] It should be noted that a control panel is installed at the end of the housing 1 of the present utility model. The fan 4 creates a negative pressure in the suction air duct 3. Under the action of the pressure, the oil fume is discharged into the suction air duct 3 through the filter screen 5, and then the fan 4 discharges the oil fume. During this period, when it is necessary to blow and cool the person cooking, the control switch of the semiconductor refrigerating sheet 10 is turned on, and the refrigerating end of the semiconductor refrigerating sheet 10 starts to refrigerate. The metal sheet 11 transfers the low temperature of the semiconductor refrigerating sheet 10 to the front of the fan 9, and the fan 9 blows air on the metal sheet 11, and the air takes away the cold air and blows it towards the air outlet 7. Since one end of the heat dissipation air duct 12 is connected to the heating end of the semiconductor refrigerating sheet 10 and the other end of the heat dissipation air duct 12 is connected to the suction air duct 3, the fan 4 forms a negative pressure inside the suction air duct 3. Under the action of the negative pressure, the heat dissipated by the semiconductor refrigerating sheet 10 enters the suction air duct 3 through the heat dissipation air duct 12, and finally follows the oil fume and is discharged from the outlet of the fan 4 and discharged from the air outlet 7, so as to cool the periphery of the range hood and provide a comfortable operating environment.

[0024] Please refer to Figure 1 , 4 , as shown in the figure, a limit plate 15 is fixedly connected to the outside of the limit pin 16, a slot hole matching the limit plate 15 is opened on the side of the housing 1, a compression spring 17 is installed between the slot hole and the limit plate 15, and an oil collecting tank 13 is snap-fitted to the inner wall of the housing 1 and at the bottom of the filter screen 5.

[0025] It should be noted that a support plate cooperating with the filter screen 5 is provided on the inner wall of the outer shell 1 of the present utility model. One end of the filter screen 5 is placed on the top of the support plate, and then the other end of the filter screen 5 is rotated to the top of the inner wall of the outer shell 1. The limiting plate 15 is pulled, and the limiting plate 15 pulls the compression spring 17. When the limiting pin 16 corresponds to the positioning hole on the side of the filter screen 5, the limiting pin 16 is released. Under the pulling force of the compression spring 17, one end of the limiting pin 16 is inserted into the side of the filter screen 5, thereby realizing the installation of the filter screen 5. When the filter screen 5 is disassembled and replaced, the limiting pin 16 is pulled out from the side of the filter screen 5, and then the filter screen 5 is removed from the top of the support plate. A metal plate for supporting the oil collecting tank 13 is fixedly connected to the inner wall of the outer shell 1, and magnets with opposite magnetic poles are fixedly connected between the outer side of the oil collecting tank 13 and the inner wall of the outer shell 1. During installation, the oil collecting tank 13 is placed on the top of the metal plate, and the positions of the two magnets are corresponding, so as to fix the oil collecting tank 13 at the bottom of the filter screen 5 by magnetic force. Since the filter screen 5 is inclined, the filtered oil stains flow downward under the action of gravity and flow into the oil collecting tank 13.

[0026] Please refer to Figure 2 As shown, a fan 4 is fixedly connected inside the exhaust air duct 18, and the air inlet of the fan 4 is communicated with the exhaust air duct 3.

[0027] It should be noted that a fan 4 is fixedly connected inside the exhaust air duct 18 of the present utility model. The fan 4 is a centrifugal fan. The air inlet of the fan 4 is connected to the inside of the exhaust air duct 3, and the output end of the fan 4 is connected to the oil fume discharge pipe. Through the high-intensity air extraction of the fan 4, a negative pressure is formed inside the exhaust air duct 3. The exhaust air duct 3 is communicated with the outer shell 1, so that the oil fume enters the exhaust air duct 3 through the filter screen 5 and then

[0028] Please refer to Figure 3 As shown, an air inlet channel 8 is provided inside the cold air box 6. A fan 9 is installed outside the air inlet channel 8, and the air inlet of the fan 9 is communicated with the air inlet channel 8. Both ends of the air inlet channel 8 are fixedly connected to the outer shell 1, and an air inlet filter screen 14 is provided at the position of the outer shell 1 corresponding to the air inlet channel 8. The cold air box 6 is provided with an air outlet 7 at the position corresponding to the air outlet of the fan 9.

[0029] It should be noted that the fan 9 of the present utility model blows the air inside the air inlet channel 8 towards the metal sheet 11. During this period, the air outside the outer shell 1 enters the air inlet channel 8 through the air inlet filter screen 14 and then is discharged from the air outlet 7 through the fan 9. During this period, the semiconductor refrigeration sheet 10 cools the metal sheet 11, and the air passing through the metal sheet 11 forms cold air, which is blown out from the air outlet 7 to cool the surrounding area.
