[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0028] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0029] See also Figure 1-10 The utility model provides a technical solution of a water mist smoke hood with a fresh air curtain:

[0030] A water mist hood with a fresh air curtain comprises an oil fume removal component 1 and a fresh air component 2 and a connecting plate 3 for connecting the oil fume removal component 1 and the fresh air component 2, the fresh air component 2 comprises an air hood 201, a mounting opening is provided on the top of the air hood 201, and an air curtain fan 202 is fixedly connected to the inner wall of the mounting opening, an air outlet is provided on the front of the air hood 201, and a fresh air outlet plate 203 is fixedly connected to the inner wall of the air outlet, and a post air outlet 204 is provided at the bottom of the air hood 201.

[0031] Specifically, by setting the post air vent 204, the wind curtain fan 202 can discharge fresh air from the post air vent 204 when working, and blow it around the user standing in front of the stove, so that a fresh air curtain is generated around the cooking equipment, reducing the radiant heat released by the cooking equipment, improving the user's comfort, and solving the problem in the prior art that the fresh air system cannot play a role for the user.

[0032] The inner wall of the post air outlet 204 is fixedly connected with an air outlet regulating valve 205. By setting the air outlet regulating valve 205, the wind direction and size of the air outlet of the post air outlet 204 can be adjusted for user selection to improve comfort.

[0033] The oil fume removal assembly 1 includes an outer cover 101, an exhaust flange 102 is arranged on the top of the outer cover 101, a guide plate 103 is fixedly connected to the inner wall of the outer cover 101, and a smoke inlet 104 is formed on the front of the outer cover 101. When in use, the oil fume enters the outer cover 101 from the smoke inlet 104, contacts the water curtain, and is purified before being discharged from the top of the outer cover 101.

[0034] The bottom of the outer cover 101 is fixedly connected with a water inlet pipe 105 , and the bottom of the outer cover 101 is fixedly connected with an overflow pipe 106 . Water is injected into the outer cover 101 through the water inlet pipe 105 , and excess water is discharged at the bottom of the outer cover 101 by setting the overflow pipe 106 .

[0035] A first slot is provided on the front of the outer cover 101, and a water level observation window 107 is fixedly connected to the inner wall of the first slot. A second slot is provided on the front of the guide plate 103, and a water curtain observation window 108 is fixedly connected to the inner wall of the second slot. The water level at the bottom of the outer cover 101 is observed by setting the water level observation window 107, and the water curtain is observed through the water curtain observation window 108.

[0036] Both sides of the wind hood 201 are fixedly connected with side panels 4, the side panels 4 are hollow, and a connecting port 5 is opened on the inner side of the side panels 4. The side panels 4 are connected with the wind hood 201 through the connecting port 5. The opposite surfaces of the two side panels 4 and the back side of the wind hood 201 are opened with first spray holes, and a horizontal nozzle 6 is arranged in the first spray hole. The lower surfaces of the side panels 4 and the wind hood 201 are opened with second spray holes, and a vertical nozzle 7 is arranged in the second spray hole. The oil smoke is introduced into the smoke inlet 104 through the horizontal nozzle 6, and a vertical air curtain is formed through the vertical nozzle 7 to prevent the oil smoke from escaping. Through the connecting port 5, the fresh air introduced into the wind hood 201 by the wind curtain fan 202 enters the side panels 4.

[0037] A fixed pipe 8 is fixedly connected to the inside of the wind hood 201. The fixed pipe 8 is open at both ends, and the two ends of the fixed pipe 8 correspond to the connecting ports 5 on both sides. The fixed pipe 8 is connected to the horizontal nozzle 6 and the vertical nozzle 7 located on the wind hood 201. A fixed plate 9 is fixedly connected to the inner wall of the side panel 4. An air duct 10 is formed inside the side panel 4 below the fixed plate 9. The air duct 10 is connected to the wind hood 201, and the air duct 10 is connected to the horizontal nozzle 6 and the vertical nozzle 7 located on the side panel 4. By setting the fixed pipe 8, fresh air enters the fixed pipe 8 from the side panel 4, and then is ejected from the horizontal nozzle 6 and the vertical nozzle 7 corresponding to the fixed pipe 8. The air duct 10 is formed by setting the fixed plate 9, and fresh air enters the corresponding horizontal nozzle 6 and the vertical nozzle 7 from the air duct 10 and is ejected outward.

[0038] Working principle: when the water mist hood with fresh air curtain is used, turn on the fan (the fan is connected to the water mist hood in the present application and is arranged at the far end), so that negative pressure is formed in the outer cover 101, and the water at the bottom of the outer cover 101 is sucked up and falls down to form a water curtain, which can also block the flame and improve the safety of the equipment; the oil smoke enters the outer cover 101 from the air inlet and contacts and mixes with the water curtain, and the purified air is discharged from the top of the outer cover 101. At the same time, when the fan is working, fresh air is sucked into the hood 201 and discharged from the fresh air outlet plate 203 and the post air outlet 204 respectively. The fresh air sprayed from the fresh air outlet plate 203 changes the air in the kitchen. The fresh air ejected from the post air vent 204 blows around the user standing in front of the stove, so that a fresh air curtain is generated around the cooking equipment, reducing the radiant heat released by the cooking equipment and improving the comfort of the user. In this process, the fresh air in the hood 201 enters the side panel 4 from the connecting port 5, and then enters the fixed pipe 8 and the air duct 10 respectively, and is ejected outward from the bedroom nozzle and the vertical nozzle 7. The fresh air ejected from the horizontal nozzle 6 guides the oil smoke into the smoke inlet 104, and the fresh air ejected from the vertical nozzle 7 forms a vertical air curtain to prevent the oil smoke from escaping, thereby solving the problem that the fresh air system in the prior art cannot play a role for the user.
