Description
Technical Field
[0001] The utility model relates to a range hood and a kitchen system comprising the range hood. Background Art
[0002] Range hoods are usually installed above stoves. They can quickly extract and discharge to the outside the stove the waste burned by the stove and the fumes harmful to the human body generated during the cooking process, playing an important role in maintaining the kitchen environment and human health.
[0003] In actual use, in order to ensure that all the oil smoke is captured, the width of the air inlet will be set large enough. However, the parts inside the smoke hood will be exposed to the outside due to the large air inlet, which increases the probability of operators touching the internal parts and reduces the operator's operating safety. In addition, a large air inlet increases the probability of sparks or food fragments entering the smoke hood through the air inlet during cooking, increasing the risk of fire. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the defect that the components inside the smoke hood of the prior art will be exposed to the outside due to the excessively large air inlet, which increases the probability of the operator touching the internal components and reduces the operating safety of the operator. In addition, the excessively large air inlet increases the probability of sparks or food fragments entering the smoke hood from the air inlet during cooking, increasing the risk of fire, and provides a range hood and a kitchen system including the same.
[0005] The utility model solves the above technical problems through the following technical solutions:
[0006] The utility model discloses a range hood, which comprises a smoke collecting hood and a smoke baffle. The smoke collecting hood is provided with an air inlet on the air inlet surface facing the cooker, the lower surface of the air inlet is connected with the smoke baffle, the smoke baffle extends obliquely upward from the lower surface of the air inlet, and in the axial direction of the air inlet, the projection of the smoke baffle can at least cover a portion of the air inlet.
[0007] In this solution, the smoke shield can shield part of the air inlet, reduce the risk of internal components being exposed, and improve the safety of the operator. In addition, by adopting the above-mentioned structural form, the smoke shield is set to improve the ability of the air inlet to capture oil smoke, reduce the risk of oil smoke escaping, and improve the operator's experience. Specifically, the smoke shield extends obliquely upward from the lower surface of the air inlet, which can include the smoke shield extending obliquely from the lower surface of the air inlet to the outside or inside of the smoke hood. When the smoke shield extends obliquely from the lower surface of the air inlet to the outside of the smoke hood, the direction of the opening formed between the end of the smoke shield away from the lower surface and the air inlet surface will not face downward. Since the oil smoke is above the fresh air, it can prevent the opening from entering too much fresh air and affecting the entry of oil smoke, thereby improving the oil smoke collection ability of the smoke hood. When the smoke shield extends obliquely from the lower surface of the air inlet to the inside of the smoke hood, the smoke shield can provide guidance for the oil smoke to enter the smoke hood, improve the efficiency of the oil smoke entering the inside of the smoke hood, and thus improve the oil smoke collection ability of the range hood.
[0008] Preferably, the smoke baffle extends obliquely from the lower surface of the air inlet toward the outside of the smoke collecting hood.
[0009] In this solution, the oil smoke is above the fresh air. With the above structure, the direction of the opening formed between the end of the smoke baffle away from the lower surface and the air inlet surface will not face downward, so that the oil smoke can enter the opening first, thereby preventing too much fresh air from entering the opening and affecting the entry of oil smoke, thereby improving the smoke collection hood's ability to capture oil smoke.
[0010] Preferably, the opening formed between one end of the lower surface of the smoke baffle away from the air inlet and the air inlet surface is oriented vertically upward.
[0011] In the present solution, the above-mentioned structural form is adopted to further improve the probability of oil smoke entering the opening first, thereby further preventing too much fresh air from entering the opening and affecting the entry of oil smoke, and further improving the oil smoke capture capacity of the smoke hood.
[0012] Preferably, the smoke baffle extends obliquely from the lower surface of the air inlet toward the interior of the smoke collecting hood.
[0013] In this solution, the above-mentioned structural form is adopted, and the smoke shield can provide guidance for the oil smoke to enter the smoke hood from the air inlet, which facilitates the oil smoke to enter the smoke hood and reduces the spread of oil smoke in the kitchen space. In addition, the smoke shield can initially intercept some larger oil smoke particles, reducing the burden on the internal filtration system of the range hood.
[0014] Preferably, the range hood further comprises a reinforcement member, and both ends of the smoke baffle plate pass through the reinforcement member and the air inlet surface.
[0015] In this solution, the above-mentioned structural form is adopted to improve the stability and reliability of the smoke shield connection. In addition, the reinforcement, the smoke shield and the air inlet surface can form a space in which all areas except the opening are closed, thereby preventing airflow backflow, which is conducive to avoiding the formation of vortices at both ends of the smoke shield, thereby avoiding the generation of aerodynamic noise.
[0016] Preferably, the smoke baffle and the lower surface of the air inlet are integrally formed.
[0017] In this solution, the above-mentioned structural form is adopted to improve the structural strength of the smoke baffle and the lower surface.
[0018] Preferably, the air inlet comprises a main air inlet and at least one auxiliary air inlet, the main air inlet and at least one auxiliary air inlet are arranged in a surrounding manner, and the suction force of the main air inlet is greater than that of each auxiliary air inlet;
[0019] The smoke baffle is at least arranged at the secondary air inlet.
[0020] In this solution, the suction force of the main air inlet is respectively greater than the suction force of each auxiliary air inlet, so that the main air inlet has a greater pulling capacity for oil smoke than each auxiliary air inlet. With the above-mentioned structural form, when the oil smoke generated by cooking reaches the vicinity of the air inlet surface, since the suction force of the main air inlet is respectively greater than the suction force of each auxiliary air inlet, the oil smoke is first adsorbed to the inside of the smoke hood through the main air inlet. When the amount of oil smoke is large, the oil smoke cannot be completely captured from the main air inlet immediately, and the excess oil smoke will spread to the surroundings. At this time, the diffused and escaping oil smoke will be captured by the auxiliary air inlet, thereby ensuring that the oil smoke cannot break through the auxiliary air inlet to escape, thereby improving the oil smoke capture capacity of the range hood, so that the main air inlet and the auxiliary air inlet can fully surround the oil smoke, prevent the oil smoke from escaping, and improve the user experience of the operator.
[0021] Preferably, the air inlet surface is recessed inwardly to form a cavity, and the air inlet is arranged in the cavity.
[0022] In this solution, the above-mentioned structural form is adopted, and the concave cavity can concentrate the oil smoke, so that it can be sucked into the smoke hood more effectively, reducing the diffusion of oil smoke in the kitchen space.
[0023] Preferably, the main air inlet is opened on the top wall or the side wall of the concave cavity, and at least part of the auxiliary air inlet is opened on the side wall of the concave cavity.
[0024] In this solution, the above-mentioned structural form is adopted to realize the surrounding arrangement between the main air inlet and the auxiliary air inlet. In addition, the oil smoke that is not captured by the main air inlet can escape by sticking to the top wall of the concave cavity. Since the auxiliary air inlet is opened on the side wall, the direction of the oil smoke adsorbed by the auxiliary air inlet is not perpendicular to the direction of the oil smoke escape, so that the escaped oil smoke can be captured by the auxiliary air inlet, which improves the range hood's ability to capture escaped oil smoke.
[0025] The utility model further discloses a kitchen system, which comprises the range hood as described in any one of the above items.
[0026] In the present solution, the range hood is applied to the kitchen system, and part of the air inlet can be shielded by the smoke baffle, thereby reducing the risk of internal components being exposed and improving the safety of the operator. In addition, by adopting the above-mentioned structural form, the ability of the air inlet to capture oil smoke is improved by setting the smoke baffle, reducing the risk of oil smoke escaping and improving the operator's experience. Specifically, the smoke baffle obliquely extending upward from the lower surface of the air inlet may include the smoke baffle obliquely extending from the lower surface of the air inlet to the outside or inside of the smoke hood. When the smoke baffle obliquely extends from the lower surface of the air inlet to the outside of the smoke hood, the direction of the opening formed between the end of the smoke baffle away from the lower surface and the air inlet surface will not face downward. Since the oil smoke is above the fresh air, it can prevent too much fresh air from entering the opening and affecting the entry of oil smoke, thereby improving the smoke hood's ability to capture oil smoke. When the smoke baffle extends obliquely from the lower surface of the air inlet toward the inside of the smoke hood, the smoke baffle can provide guidance for the oil smoke to enter the smoke hood, thereby improving the efficiency of the oil smoke entering the smoke hood, thereby improving the oil smoke capture capacity of the range hood.
[0027] The positive and progressive effects of the utility model are:
[0028] The smoke shield can shield part of the air inlet, reduce the risk of internal components being exposed, and improve the safety of the operator. In addition, by adopting the above-mentioned structural form, the ability of the air inlet to capture oil smoke is improved by setting the smoke shield, the risk of oil smoke escaping is reduced, and the operator's experience is improved. Specifically, the smoke shield extends obliquely upward from the lower surface of the air inlet, which may include the smoke shield extending obliquely from the lower surface of the air inlet to the outside or inside of the smoke hood. When the smoke shield extends obliquely from the lower surface of the air inlet to the outside of the smoke hood, the direction of the opening formed between the end of the smoke shield away from the lower surface and the air inlet surface will not face downward. Since the oil smoke is above the fresh air, it can prevent the opening from entering too much fresh air and affecting the entry of oil smoke, thereby improving the oil smoke collection ability of the smoke hood. When the smoke shield extends obliquely from the lower surface of the air inlet to the inside of the smoke hood, the smoke shield can provide guidance for the oil smoke to enter the smoke hood, improve the efficiency of the oil smoke entering the inside of the smoke hood, and thus improve the oil smoke collection ability of the range hood.

[0051] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0052] like Figures 1 to 6 As shown, this embodiment provides a range hood 100, which includes a smoke collecting hood 1 and a smoke baffle 2. The smoke collecting hood 1 is provided with an air inlet 111 on the air inlet surface 11 facing the cooker, and the lower surface of the air inlet 111 is connected with a smoke baffle 2. The smoke baffle 2 extends upwardly from the lower surface of the air inlet 111 obliquely, and in the axial direction of the air inlet 111, the projection of the smoke baffle 2 can at least cover part of the air inlet 111. The smoke baffle 2 can shield part of the air inlet 111, thereby reducing the risk of internal components being exposed and improving the safety of the operator. In addition, by adopting the above-mentioned structural form, the smoke baffle 2 is provided to improve the ability of the air inlet 111 to capture oil smoke, reduce the risk of oil smoke escaping, and improve the operator's experience. Specifically, the smoke baffle 2 extending upwardly obliquely from the lower surface of the air inlet 111 can include the smoke baffle 2 extending obliquely from the lower surface of the air inlet 111 to the outside or inside of the smoke collecting hood 1. When the smoke shield 2 extends obliquely from the lower surface of the air inlet 111 toward the outside of the smoke hood 1, the direction of the opening formed between the end of the smoke shield 2 away from the lower surface and the air inlet surface 11 will not face downward. Since the oil smoke is above the fresh air, it can prevent too much fresh air from entering the opening and affecting the entry of oil smoke, thereby improving the oil smoke capture capability of the smoke hood 1. When the smoke shield 2 extends obliquely from the lower surface of the air inlet 111 toward the inside of the smoke hood 1, the smoke shield 2 can provide guidance for the oil smoke to enter the smoke hood 1, thereby improving the efficiency of the oil smoke entering the inside of the smoke hood 1, thereby improving the oil smoke capture capability of the range hood 100.
[0053] In specific use, the projection of the smoke shield 2 can completely cover the air inlet 111 in the axial direction of the air inlet 111. In other embodiments, the size of the projection of the smoke shield 2 covering the air inlet 111 can be adjusted according to actual needs, which is not limited here.
[0054] like Figures 4 to 6 As shown, the smoke baffle 2 extends obliquely from the lower surface of the air inlet 111 to the outside of the smoke hood 1. Specifically, the oil smoke is above the fresh air. With the above structure, the opening formed between the end of the smoke baffle 2 away from the lower surface and the air inlet surface 11 will not face downward, so that the oil smoke can enter the opening first, thereby preventing too much fresh air from entering the opening and affecting the entry of oil smoke, thereby improving the oil smoke capture capability of the smoke hood 1.
[0055] The opening formed between the end of the lower surface of the smoke baffle 2 away from the air inlet 111 and the air inlet surface 11 is oriented vertically upward. The above structure further increases the probability that the oil smoke enters the opening first, thereby further preventing the opening from entering too much fresh air and affecting the entry of oil smoke, and further improving the oil smoke collection ability of the smoke hood 1.
[0056] In this embodiment, since the flow velocity of the oil smoke is slow and has a strong wall adhesion effect, the oil smoke moves backward along the air inlet surface 11. At this time, the opening is facing the air inlet surface 11, which is more conducive to the capture of the oil smoke.
[0057] like Figure 2 and Figure 3 As shown, the smoke shield 2 extends obliquely from the lower surface of the air inlet 111 toward the inside of the smoke hood 1. With the above-mentioned structural form, the smoke shield 2 can provide guidance for the oil smoke to enter the inside of the smoke hood 1 from the air inlet 111, which facilitates the oil smoke to enter the inside of the smoke hood 1 and reduces the spread of oil smoke in the kitchen space. In addition, the smoke shield 2 can initially intercept some larger oil smoke particles, reducing the burden on the internal filtration system of the range hood.
[0058] It should be specifically noted that when the smoke shield 2 extends into the smoke hood 1, the inclination angle of the smoke shield 2 is less than 45 degrees. In other embodiments, the inclination angle of the smoke shield 2 can be adjusted according to actual needs, and is not specifically limited here.
[0059] like Figure 2 , Figure 4 and Figure 6 As shown, the range hood 100 further includes a reinforcement member 3, and both ends of the smoke baffle 2 are connected to the air inlet surface 11 through the reinforcement member 3, thereby improving the stability and reliability of the connection between the smoke baffle 2. In addition, the reinforcement member 3, the smoke baffle 2 and the air inlet surface 11 can form a space in which all areas except the opening are closed, thereby preventing airflow from flowing back, which is beneficial to avoiding the formation of vortices at both ends of the smoke baffle 2, thereby avoiding the generation of aerodynamic noise.
[0060] In specific use, the reinforcement member 3 and the smoke baffle plate 2 are integrally formed. In other embodiments, the connection form of the reinforcement member 3 and the smoke baffle plate 2 is not limited herein.
[0061] The smoke baffle plate 2 and the lower surface of the air inlet 111 are integrally formed. The above-mentioned structural form improves the structural strength of the smoke baffle plate 2 and the lower surface.
[0062] like Figure 6 As shown, in other embodiments, a connecting portion 5 is connected to the smoke shield 2, and a fixing portion 4 is connected to the surface of the air inlet 111, and the connecting portion 5 and the fixing portion 4 are connected to fix the smoke shield 2. Specifically, the fixing portion 4 extends from the upper surface of the air inlet 111 to the lower surface of the air inlet 111; the connecting portion 5 extends upward from the lower surface of the smoke shield 2, and is connected to the fixing portion 4 through a connecting member.
[0063] like Figure 1 As shown, the air inlet 111 includes a main air inlet 1111 and at least one auxiliary air inlet 1112. The main air inlet 1111 and at least one auxiliary air inlet 1112 are arranged in a surrounding manner. The suction force of the main air inlet 1111 is greater than that of each auxiliary air inlet 1112. The smoke baffle 2 is at least provided at the auxiliary air inlet 1112. Specifically, the suction force of the main air inlet 1111 is respectively greater than that of each auxiliary air inlet 1112, so that the traction capacity of the main air inlet 1111 for oil smoke is greater than that of each auxiliary air inlet 1112. With the above-mentioned structural form, when the oil smoke generated by cooking reaches the vicinity of the air inlet surface 11, since the suction force of the main air inlet 1111 is respectively greater than that of each auxiliary air inlet 1112, the oil smoke is first adsorbed to the inside of the smoke hood 1 through the main air inlet 1111. When the amount of oil smoke is large, the oil smoke cannot be completely captured immediately from the main air inlet 1111, and the excess oil smoke will spread to the surroundings. At this time, the diffused and escaped oil smoke will be captured by the auxiliary air inlet 1112, thereby ensuring that the oil smoke cannot break through the auxiliary air inlet 1112 to escape, thereby improving the oil smoke capture ability of the range hood 100, so that the main air inlet 1111 and the auxiliary air inlet 1112 can fully surround the oil smoke, prevent the oil smoke from escaping, and improve the user experience of the operator.
[0064] like Figure 1 As shown, the air inlet surface 11 is recessed inward to form a cavity 12, and the air inlet 111 is arranged in the cavity 12. With the above structure, the cavity 12 can concentrate the oil smoke, so that it can be more effectively sucked into the smoke hood 1, reducing the diffusion of oil smoke in the kitchen space.
[0065] The main air inlet 1111 is provided on the top wall 121 or the side wall 122 of the concave cavity 12, and at least part of the auxiliary air inlet 1112 is provided on the side wall 122 of the concave cavity 12. The above-mentioned structural form realizes a surrounding arrangement between the main air inlet 1111 and the auxiliary air inlet 1112. In addition, the oil smoke that is not captured by the main air inlet 1111 can escape by sticking to the top wall 121 of the concave cavity 12. Since the auxiliary air inlet 1112 is provided on the side wall 122, the direction of the oil smoke adsorbed by the auxiliary air inlet 1112 is not perpendicular to the direction of the oil smoke escape, so that the escaped oil smoke can be captured by the auxiliary air inlet 1112, thereby improving the capture ability of the range hood 100 for the escaped oil smoke.
[0066] It should be specifically explained that, in the present embodiment, the air inlet 111 is provided on the top wall 121 of the concave cavity 12, and the auxiliary air inlet 1112 is provided on the side wall 122 of the concave cavity 12. In addition, the auxiliary air inlet 1112 includes a first auxiliary air inlet 11121 and a second auxiliary air inlet 11122, both of which are provided on the side wall 122 of the concave cavity 12, and the first auxiliary air inlet 11121 is closer to the main air inlet 1111 than the second auxiliary air inlet 11122, wherein the first auxiliary air inlet 11121 is larger than the second auxiliary air inlet 11122. By adopting the above-mentioned structural form, the oil fume not absorbed by the main air inlet 1111 will first escape in the direction of the setting position of the first auxiliary air inlet 11121, so that most of the escaped oil fume is captured by the first auxiliary air inlet 11121, and then the oil fume not captured by the first auxiliary air inlet 11121 will escape in the direction of the setting position of the second auxiliary air inlet 11122, so that the remaining oil fume is captured by the second auxiliary air inlet 11122, and then all the oil fume is captured by the range hood 100, thereby improving the oil fume capture capacity of the range hood 100.
[0067] This embodiment continues to provide a kitchen system, which includes a range hood 100. Specifically, the range hood 100 is applied to the kitchen system, and the smoke baffle 2 can shield part of the air inlet 111, thereby reducing the risk of internal components being exposed and improving the safety of the operator. In addition, by adopting the above-mentioned structural form, the smoke baffle 2 is provided to improve the ability of the air inlet 111 to capture oil smoke, reduce the risk of oil smoke escaping, and improve the operator's experience. Specifically, the smoke baffle 2 extends obliquely upward from the lower surface of the air inlet 111, which may include the smoke baffle 2 extending obliquely from the lower surface of the air inlet 111 to the outside or inside of the smoke hood 1. When the smoke baffle 2 extends obliquely from the lower surface of the air inlet 111 to the outside of the smoke hood 1, the direction of the opening formed between the end of the smoke baffle 2 away from the lower surface and the air inlet surface 11 will not face downward. Since the oil smoke is above the fresh air, it can prevent the opening from entering too much fresh air and affecting the entry of oil smoke, thereby improving the oil smoke capture ability of the smoke hood 1. When the smoke baffle 2 extends obliquely from the lower surface of the air inlet 111 toward the inside of the smoke hood 1, the smoke baffle 2 can provide guidance for the oil smoke to enter the smoke hood 1, thereby improving the efficiency of the oil smoke entering the smoke hood 1, thereby improving the oil smoke capture capability of the range hood 100.
[0068] In specific use, the kitchen system is a combination of common kitchen appliances such as a range hood 100 and a stove that are commonly used in daily kitchens.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
