Description

Technical Field

[0001] This application relates to the technical field of kitchen utensils, and particularly to range hoods and cooking appliances. Background Art

[0002] When camping outdoors, dining is often inconvenient. People either choose takeout or rely solely on the snacks they bring. However, it is very likely that there is no satisfactory takeout near the campsite, and snacks are usually not nutritious, resulting in people having difficulty maintaining their usual diet quality during camping and reducing the camping experience. To enhance the camping experience, it is possible to consider carrying cooking appliances and ingredients in the vehicle and powering the cooking appliances with a portable power source after arriving at the campsite to cook food. This can not only ensure the diet quality but also enjoy the picnic experience, thus enhancing the camping experience.

[0003] However, a large amount of oil fume is generated during the cooking process. If not properly treated, this oil fume will spread near the campsite, affecting the surrounding environment and reducing the camping experience. Therefore, it is necessary to treat the oil fume. It is possible to consider integrating a range hood on the cooking appliance to treat the oil fume. However, due to the unstable environmental conditions at the campsite, whether there is wind, the change of wind direction, etc. are all uncertain, making the oil fume treatment at the campsite complicated. When there is no wind at the campsite, placing the smoke inlet of the range hood (the inlet on the range hood for the oil fume to enter) directly above and close to the position where the oil fume is generated helps to efficiently extract the oil fume; when there is wind at the campsite, making the smoke inlet of the range hood close to the position where the oil fume is generated and facing the flowing direction of the oil fume helps to efficiently extract the oil fume. In short, to efficiently extract the oil fume at the campsite, the position and orientation of the smoke inlet of the range hood need to be adjustable. Although some existing cooking appliances integrate range hoods, in these cooking appliances, the position and orientation of the smoke inlet of the range hood are fixed and cannot be adjusted. Such range hoods are suitable for stable indoor environments without wind and are not suitable for the campsite environment. Summary of the Utility Model

[0004] Based on this, in view of the above problems, it is necessary to provide a range hood and a cooking appliance, the position and orientation of the smoke inlet of which can be adjusted, so that the cooking appliance with this range hood is suitable for the campsite environment.

[0005] To solve the above problems, the technical solutions provided by this application are as follows:

[0006] A cooking appliance, which includes:

[0007] Smoking pipe, comprising a first pipe section, a second pipe section, a first clamping assembly, a first ball head, a third pipe section, a fourth pipe section, a second clamping assembly, a second ball head, a fifth pipe section, a sixth pipe section and a seventh pipe section; the first pipe section, the second pipe section, the third pipe section, the fourth pipe section, the fifth pipe section, the sixth pipe section and the seventh pipe section are all rigid bodies; the second pipe section is fixedly arranged at one end of the first pipe section, the first clamping assembly comprises a first ball shell and at least three first elastic claws, the first ball shell is fixedly arranged at the end of the second pipe section far away from the first pipe section, the first ball head is arranged in the first ball shell and is in profile adaptation with the inner side of the first ball shell, the first ball shell has a first opening for the first ball head to enter and exit, each of the first elastic claws is fixedly arranged at the edge of the first opening and is circumferentially spaced along the edge of the first opening, and each first elastic claw is in profile adaptation with the first ball head and is arranged in contact with the first ball head; the first ball head and the fourth pipe section are respectively fixedly arranged at both ends of the third pipe section; the second clamping assembly comprises a second ball shell and at least three second elastic claws, the second ball shell is fixedly arranged at the end of the fourth pipe section far away from the third pipe section, the second ball head is arranged in the second ball shell and is in profile adaptation with the second ball shell, the second ball shell has a second opening for the second ball head to enter and exit, each of the second elastic claws is fixedly arranged at the edge of the second opening and is circumferentially spaced along the edge of the second opening, and each second elastic claw is in profile adaptation with the second ball head and is arranged in contact with the second ball head; one end of the fifth pipe section is fixedly arranged on the second ball head, the sixth pipe section is fixedly arranged at the end of the fifth pipe section far away from the second ball head, and the seventh pipe section is fixedly arranged at the end of the sixth pipe section far away from the fifth pipe section; the first pipe section, the second pipe section, the first ball shell, the first ball head, the third pipe section, the fourth pipe section, the second ball shell, the second ball head, the fifth pipe section, the sixth pipe section and the seventh pipe section are all of hollow structure and are communicated in sequence, there is an included angle between the first pipe section and the second pipe section, there is an included angle between the third pipe section and the fourth pipe section, and there are included angles between any two of the fifth pipe section, the sixth pipe section and the seventh pipe section; the pipe orifice at the end of the seventh pipe section far away from the sixth pipe section is a smoking port, and the pipe orifice at the end of the first pipe section far away from the second pipe section is an exhaust port;

[0008] A blower, arranged in the first pipe section, for enabling external gas to enter the smoking pipe from the smoking port and be discharged from the exhaust port of the smoking pipe; and

[0009] A filter, arranged in the first pipe section, for absorbing oil fume in the gas flowing through the smoking pipe.

[0010] This oil fume extractor has at least the following beneficial effects:

[0011] Because the second pipe segment and the third pipe segment are connected by the first engaging component and the first ball head, and the fourth pipe segment and the fifth pipe segment are connected by the second engaging component and the second ball head, when the user applies force, the third pipe segment can rotate relative to the second pipe segment, and the fifth pipe segment can rotate relative to the fourth pipe segment, and the second pipe segment, the first ball shell, the first ball head and the third pipe segment are still connected in sequence, and the fourth pipe segment, the second ball shell, the second ball head and the fifth pipe segment are still connected in sequence; after the user stops applying force, the first elastic claw holds the first ball head, and the second elastic claw holds the second ball head, thereby fixing the third pipe segment and the fifth pipe segment. In other words, the position and direction of the smoke outlet can be adjusted by rotating the third pipe segment and the fifth pipe segment. When integrating the range hood, the first pipe segment can be installed on a cabinet (such as Figure 1 As shown), and place the smoke outlet above the cooking utensil (such as a frying pan / wok / hot pot). When camping outdoors, adjust the position and orientation of the smoke outlet according to the wind speed and direction of the campsite, so that the smoke outlet is close to the cooking utensil and faces the flow direction of the oil smoke. In this way, the smoke pipe can efficiently collect the oil smoke, and the range hood can efficiently absorb the oil smoke, reduce the spread of oil smoke near the campsite, and enhance the user's camping experience. Therefore, the cooking equipment with the range hood is suitable for the campsite environment. For example: when there is no wind in the campsite, the smoke outlet can be placed directly above the cooking utensil and close to the cooking utensil, and the smoke outlet can be facing downward to efficiently absorb the oil smoke; when there is wind in the campsite, the smoke outlet can be close to the cooking utensil and face the flow direction of the oil smoke to efficiently absorb the oil smoke.

[0012] Furthermore, the first pipe section can be rotatably connected to the cabinet, so that the first pipe section can also be rotated, which can increase the flexibility of adjusting the position and direction of the smoking port.

[0013] In addition, when assembling the smoking pipe, it is only necessary to pry open the first elastic claw, so that the first ball head enters the first ball shell from the first opening, and after releasing the first elastic claw, the first elastic claw returns to its original state and can hold the first ball head tightly; it is only necessary to pry open the second elastic claw, so that the second ball head enters the second ball shell from the second opening, and after releasing the second elastic claw, the second elastic claw returns to its original state and can hold the second ball head tightly. When disassembling the smoking pipe, it is only necessary to pry open the first elastic claw and the second elastic claw, and remove the first ball head and the second ball head. Therefore, the range hood is easy to assemble and disassemble.

[0014] In one embodiment, the first pipe segment and the second pipe segment are perpendicular to each other, the third pipe segment and the fourth pipe segment are perpendicular to each other, and the fifth pipe segment, the sixth pipe segment and the seventh pipe segment are perpendicular to each other.

[0015] Such an arrangement is conducive to increasing the activity space of the smoking opening and flexibly adjusting the position and direction of the smoking opening.

[0016] In one embodiment, at least three of the first elastic claws abut against the third pipe section.

[0017] With such an arrangement, it is beneficial to fix the third pipe section, improve the stability of the smoking pipe, and prevent the position and orientation of the smoking port from deviating.

[0018] In one embodiment, at least three of the second elastic claws abut against the fifth pipe section.

[0019] With such an arrangement, it is beneficial to fix the fifth pipe section, improve the stability of the smoking pipe, and prevent the position and orientation of the smoking port from deviating.

[0020] In one embodiment, each of the first elastic claws is circumferentially and uniformly distributed along the edge of the first opening.

[0021] With such an arrangement, it is beneficial to fix the first ball head, improve the stability of the smoking pipe, and prevent the position and orientation of the smoking port from deviating.

[0022] In one embodiment, each of the second elastic claws is circumferentially and uniformly distributed along the edge of the second opening.

[0023] With such an arrangement, it is beneficial to fix the second ball head, improve the stability of the smoking pipe, and prevent the position and orientation of the smoking port from deviating.

[0024] In one embodiment, both the first elastic claw and the second elastic claw are made of spring steel.

[0025] With such an arrangement, the first elastic claw and the second elastic claw have sufficient elastic force to ensure that they hold the first ball head and the second ball head tightly.

[0026] In one embodiment, the first pipe section is a solid of revolution.

[0027] With such an arrangement, it is convenient to rotatably connect the first pipe section to the cabinet.

[0028] This application also provides a cooking device, which includes:

[0029] A cabinet, with a cooking area provided on the top side of the cabinet;

[0030] A cooking module, provided in the cooking area; and

[0031] The above-mentioned range hood, the first pipe section is rotatably connected to the cabinet, and the smoking port is located above the cooking area.

[0032] This cooking device has at least the following beneficial effects:

[0033] Since the first pipe section is rotatably connected to the cabinet, the second pipe section and the third pipe section are connected by a first clamping assembly and a first ball head, and the fourth pipe section and the fifth pipe section are connected by a second clamping assembly and a second ball head, therefore, when a user applies force, the first pipe section can rotate relative to the cabinet, the third pipe section can rotate relative to the second pipe section, and the fifth pipe section can rotate relative to the fourth pipe section; after the user stops applying force, the first elastic claw clamps the first ball head, and the second elastic claw clamps the second ball head, thereby fixing the third pipe section and the fifth pipe section. In other words, the position and orientation of the smoking port can be adjusted by rotating the first pipe section, the third pipe section, and the fifth pipe section. When camping outdoors, adjust the position and orientation of the smoking port according to the wind speed and direction at the camping site, so that the smoking port is close to the cooking appliance and faces the flow direction of the cooking fumes. In this way, the smoking pipe can efficiently collect the cooking fumes, the range hood can efficiently extract the cooking fumes, reduce the diffusion of the cooking fumes near the campsite, and improve the user's camping experience. Therefore, this cooking device is suitable for the camping site environment.

[0034] In one embodiment, a mounting seat protrudes from the outside of the cabinet, the mounting seat is disposed opposite to the outer side surface of the first pipe section, a wing screw is threadedly connected to the mounting seat, and the first pipe section is located on the moving path of the wing screw.

[0035] With such a setting, after loosening the wing screw and applying force to the first pipe section, the first pipe section can be rotated; after the first pipe section rotates through a suitable angle so that the smoking port is in a suitable position and orientation, tighten the wing screw, and the fixing of the first pipe section can be achieved to prevent the first pipe section from continuing to rotate and causing the smoking port to deviate from the suitable position and suitable orientation.

[0036] In one embodiment, the wing screw is a flat-bottom screw.

[0037] With such a setting, it is beneficial to prevent damage to the first pipe section after tightening the wing screw.

[0038] In one embodiment, the first pipe section is slidably connected to the cabinet.

[0039] With such a setting, it is beneficial to flexibly adjust the position of the smoking port. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Referring to Figures 1 to 5 , this application first provides a range hood 1, which includes a suction pipe 11, a blower 12 and a filter 13. Referring to Figures 2 to 4, the smoking pipe 11 includes a first pipe section 111, a second pipe section 112, a first clamping assembly 118, a first ball head 119, a third pipe section 113, a fourth pipe section 114, a second clamping assembly 120, a second ball head 121, a fifth pipe section 115, a sixth pipe section 116 and a seventh pipe section 117. The first pipe section 111, the second pipe section 112, the third pipe section 113, the fourth pipe section 114, the fifth pipe section 115, the sixth pipe section 116 and the seventh pipe section 117 are all rigid bodies. The second pipe section 112 is fixedly arranged at one end of the first pipe section 111. The first clamping assembly 118 includes a first ball shell 1181 and at least three elastic first elastic claws 1182. The first ball shell 1181 is fixedly arranged at the end of the second pipe section 112 away from the first pipe section 111. The first ball head 119 is arranged in the first ball shell 1181 and is conformally adapted to the inner side of the first ball shell 1181. The first ball shell 1181 has a first opening 11811 for the first ball head 119 to enter and exit (as Figure 4 shown), and each first elastic claw 1182 is fixedly arranged at the edge of the first opening 11811 and is circumferentially spaced along the edge of the first opening 11811. Each first elastic claw 1182 is conformally adapted to the first ball head 119 and is arranged in contact with the first ball head 119. The first ball head 119 and the fourth pipe section 114 are respectively fixedly arranged at both ends of the third pipe section 113. The second clamping assembly 120 includes a second ball shell 1201 and at least three elastic second elastic claws 1202. The second ball shell 1201 is fixedly arranged at the end of the fourth pipe section 114 away from the third pipe section 113. The second ball head 121 is arranged in the second ball shell 1201 and is conformally adapted to the second ball shell 1201. The second ball shell 1201 has a second opening 12011 for the second ball head 121 to enter and exit (as Figure 4As shown, each second elastic claw 1202 is fixedly arranged at the edge of the second opening 12011 and is circumferentially spaced along the edge of the second opening 12011. Each second elastic claw 1202 is shaped to fit the second ball head 121 and is arranged in contact with the second ball head 121. One end of the fifth pipe section 115 is fixedly arranged at the second ball head 121. The sixth pipe section 116 is fixedly arranged at the end of the fifth pipe section 115 away from the second ball head 121. The seventh pipe section 117 is fixedly arranged at the end of the sixth pipe section 116 away from the fifth pipe section 115. The first pipe section 111, the second pipe section 112, the first spherical shell 1181, the first ball head 119, the third pipe section 113, the fourth pipe section 114, the second spherical shell 1201, the second ball head 121, the fifth pipe section 115, the sixth pipe section 116, and the seventh pipe section 117 are all hollow structures and are connected in sequence. There is an included angle between the first pipe section 111 and the second pipe section 112, an included angle between the third pipe section 113 and the fourth pipe section 114, and included angles between any two of the fifth pipe section 115, the sixth pipe section 116, and the seventh pipe section 117. In other words, the first pipe section 111 and the second pipe section 112 are not on the same straight line, the third pipe section 113 and the fourth pipe section 114 are not on the same straight line, and any two of the fifth pipe section 115, the sixth pipe section 116, and the seventh pipe section 117 are not on the same straight line and are not parallel.

[0055] Refer to Figure 3 , the pipe orifice at the end of the seventh pipe section 117 away from the sixth pipe section 116 is the smoking port 1171, and the pipe orifice at the end of the first pipe section 111 away from the second pipe section 112 is the exhaust port 1111.

[0056] Refer to Figure 5 , the fan 12 is arranged in the first pipe section 111 and is used to make the outside gas enter the smoking pipe 11 from the smoking port 1171 and be discharged from the exhaust port 1111 of the smoking pipe 11. The filter 13 is arranged in the first pipe section 111 and is used to absorb the oil fume in the gas flowing through the smoking pipe 11.

[0057] Since the second pipe section 112 and the third pipe section 113 are connected by the first clamping assembly 118 and the first ball head 119, and the fourth pipe section 114 and the fifth pipe section 115 are connected by the second clamping assembly 120 and the second ball head 121, therefore, under the force applied by the user, the third pipe section 113 can rotate relative to the second pipe section 112, and the fifth pipe section 115 can rotate relative to the fourth pipe section 114. Moreover, the second pipe section 112, the first ball shell 1181, the first ball head 119 and the third pipe section 113 are still connected in sequence, and the fourth pipe section 114, the second ball shell 1201, the second ball head 121 and the fifth pipe section 115 are still connected in sequence; after the user stops applying force, the first elastic claw 1182 clamps the first ball head 119, and the second elastic claw 1202 clamps the second ball head 121, thereby fixing the third pipe section 113 and the fifth pipe section 115. In other words, by rotating the third pipe section 113 and the fifth pipe section 115, the position and orientation of the smoke suction port 1171 can be adjusted. When integrating the range hood 1, the first pipe section 111 can be installed on the cabinet 2 (as Figure 1 shown), and the smoke suction port 1171 can be placed above the cooking appliance (such as an electric hot pot / electric griddle / electric cooker / electric wok). When camping outdoors, adjust the position and orientation of the smoke suction port 1171 according to the wind speed and direction at the camping site, so that the smoke suction port 1171 is close to the cooking appliance and faces the flowing direction of the oil fume. In this way, the smoke suction pipe 11 can efficiently collect the oil fume, the range hood 1 can efficiently suck the oil fume, reduce the diffusion of the oil fume near the camping site, and improve the user's camping experience. Therefore, the cooking device with the range hood 1 is suitable for the camping site environment. For example: when there is no wind at the camping site, the smoke suction port 1171 can be placed directly above and close to the cooking appliance, and the smoke suction port 1171 can be oriented downward to efficiently suck the oil fume; when there is wind at the camping site, the smoke suction port 1171 can be close to the cooking appliance and the smoke suction port 1171 can face the flowing direction of the oil fume to efficiently suck the oil fume.

[0058] Moreover, the first pipe section 111 can be rotatably connected to the cabinet 2, so that the first pipe section 111 can also rotate, which can increase the flexibility of adjusting the position and orientation of the smoke suction port 1171.

[0059] In addition, when assembling the smoking pipe 11, it is only necessary to pry open the first elastic claw 1182 so that the first ball head 119 enters the first ball shell 1181 from the first opening 11811. After releasing the first elastic claw 1182, the first elastic claw 1182 returns to its original state and can hold the first ball head 119 tightly. It is only necessary to pry open the second elastic claw 1202 so that the second ball head 121 enters the second ball shell 1201 from the second opening 12011. After releasing the second elastic claw 1202, the second elastic claw 1202 returns to its original state and can hold the second ball head 121 tightly. When disassembling the smoking pipe 11, it is only necessary to pry open the first elastic claw 1182 and the second elastic claw 1202 and remove the first ball head 119 and the second ball head 121. Therefore, the range hood 1 is easy to assemble and disassemble.

[0060] The length direction of the first pipe segment 111 is defined as the first direction, the length direction of the second pipe segment 112 is defined as the second direction, and the length direction of the fourth pipe segment 114 is defined as the third direction. Figure 1 In the state shown, the first direction is the Y direction, the second direction is the Z direction, and the third direction is the X direction.

[0061] Exemplarily, the first tube segment 111 has a first through hole along the first direction, the second tube segment 112 has a second through hole along the second direction, the first ball shell 1181 has a third through hole along the second direction, the first ball head 119 has a fourth through hole along the second direction, the third tube segment 113 has a fifth through hole along the second direction, the fourth tube segment 114 has a sixth through hole along the third direction, the second ball shell 1201 has a seventh through hole along the third direction, the second ball head 121 has an eighth through hole along the third direction, the fifth tube segment 115 has a ninth through hole along the third direction, the sixth tube segment 116 has a tenth through hole along the first direction, and the seventh tube segment 117 has an eleventh through hole along the second direction. The first through hole, the second through hole, the third through hole, the fourth through hole, the fifth through hole, the sixth through hole, the seventh through hole, the eighth through hole, the ninth through hole, the tenth through hole and the eleventh through hole are connected in sequence. Figure 1 In the state shown, when adjusting the position and orientation of the smoking port 1171, the third tube segment 113 can be rotated around the axis of the Z axis, and the fifth tube segment 115 can be rotated around the axis of the X axis.

[0062] Exemplarily, the number of the first elastic claws 1182 is 3 / 4 / 5 / 6 / 7 / 8, and the number of the second elastic claws 1202 is 3 / 4 / 5 / 6 / 7 / 8.

[0063] Preferably, in some embodiments, the first pipe section 111, the second pipe section 112, the third pipe section 113, the fourth pipe section 114, the fifth pipe section 115, the sixth pipe section 116, and the seventh pipe section 117 are all straight pipes. The first pipe section 111 and the second pipe section 112 are perpendicular to each other, the third pipe section 113 and the fourth pipe section 114 are perpendicular to each other, and the fifth pipe section 115, the sixth pipe section 116, and the seventh pipe section 117 are perpendicular to each other pairwise. In this way, it is beneficial to increase the moving space of the smoking port 1171 and is beneficial to flexibly adjust the position and orientation of the smoking port 1171. In other embodiments, the angles between the first pipe section 111 and the second pipe section 112, between the third pipe section 113 and the fourth pipe section 114, between the fifth pipe section 115 and the sixth pipe section 116, and between the sixth pipe section 116 and the seventh pipe section 117 can all be less than or greater than 90°.

[0064] In some embodiments, at least three first elastic claws 1182 abut against the third pipe section 113. In this way, it is beneficial to fix the third pipe section 113, beneficial to improve the stability of the smoking pipe 11, and beneficial to prevent the position and orientation of the smoking port 1171 from deviating.

[0065] In some embodiments, at least three second elastic claws 1202 abut against the fifth pipe section 115. In this way, it is beneficial to fix the fifth pipe section 115, beneficial to improve the stability of the smoking pipe 11, and beneficial to prevent the position and orientation of the smoking port 1171 from deviating.

[0066] Refer to Figure 4 , each of the first elastic claws 1182 is evenly distributed circumferentially along the edge of the first opening 11811. This is beneficial to fix the first ball head 119, beneficial to improve the stability of the smoking pipe 11, and beneficial to prevent the position and orientation of the smoking port 1171 from deviating. In other embodiments, each of the first elastic claws 1182 can also be unevenly distributed circumferentially.

[0067] Refer to Figure 4 , each of the second elastic claws 1202 is evenly distributed circumferentially along the edge of the second opening 12011. This is beneficial to fix the second ball head 121, beneficial to improve the stability of the smoking pipe 11, and beneficial to prevent the position and orientation of the smoking port 1171 from deviating. In other embodiments, each of the first elastic claws 1182 can also be unevenly distributed circumferentially.

[0068] Preferably, both the first elastic claw 1182 and the second elastic claw 1202 are made of spring steel. In this way, the first elastic claw 1182 and the second elastic claw 1202 have sufficient elasticity to ensure clamping the first ball head 119 and the second ball head 121. In other embodiments, the first elastic claw 1182 and the second elastic claw 1202 can also be made of plastic with good toughness.

[0069] Preferably, the first spherical shell 1181 and the first elastic claw 1182 are made of the same material, and the second spherical shell 1201 and the second elastic claw 1202 are made of the same material.

[0070] Exemplarily, the first pipe section 111, the second pipe section 112, the third pipe section 113, the fourth pipe section 114, the fifth pipe section 115, the sixth pipe section 116, the seventh pipe section 117, the first ball head 119 and the second ball head 121 are all made of stainless steel.

[0071] Referring to Figure 4 , the first pipe section 111 is a solid of revolution, which facilitates the rotational connection of the first pipe section 111 to the cabinet 2. For example: a through hole adapted to the first pipe section 111 is provided horizontally on the cabinet 2, and the first pipe section 111 is installed in the through hole, so that the first pipe section 111 and the cabinet 2 can form a rotational connection, as Figure 1 shown.

[0072] Referring to Figure 1 , the present application secondly provides a cooking device, which includes a cabinet 2, a cooking module 3 and the above-mentioned range hood 1. A cooking area 21 is provided on the top side of the cabinet 2, the cooking module 3 is arranged in the cooking area 21, and food is cooked in the cooking module 3. The first pipe section 111 is rotationally connected to the cabinet 2, and the smoke suction port 1171 is located above the cooking area 21. Since the first pipe section 111 is rotationally connected to the cabinet 2, the second pipe section 112 and the third pipe section 113 are connected by the first clamping assembly 118 and the first ball head 119, and the fourth pipe section 114 and the fifth pipe section 115 are connected by the second clamping assembly 120 and the second ball head 121. Therefore, when a user applies force, the first pipe section 111 can rotate relative to the cabinet 2, the third pipe section 113 can rotate relative to the second pipe section 112, and the fifth pipe section 115 can rotate relative to the fourth pipe section 114; after the user stops applying force, the first elastic claw 1182 clamps the first ball head 119, and the second elastic claw 1202 clamps the second ball head 121, thereby fixing the third pipe section 113 and the fifth pipe section 115. In other words, by rotating the first pipe section 111, the third pipe section 113 and the fifth pipe section 115, the position and orientation of the smoke suction port 1171 can be adjusted. When camping outdoors, according to the wind speed and direction at the camping site, the position and orientation of the smoke suction port 1171 are adjusted so that the smoke suction port 1171 is close to the cooking appliance and faces the flowing direction of the cooking fumes. In this way, the smoke suction pipe 11 can efficiently collect the cooking fumes, the range hood 1 can efficiently suck the cooking fumes, reduce the diffusion of the cooking fumes near the camping site, and improve the camping experience of the user. Therefore, the cooking device is suitable for the camping site environment.

[0073] Exemplarily, the cooking module 3 is an electric hot pot / electric griddle / electric cooker / electric wok.

[0074] In some embodiments, a handle is convexly provided on the first pipe section 111. The handle is located outside the cabinet 2, and the user can rotate the first pipe section 111 by applying a force to the handle. In other embodiments, no handle is provided on the first pipe section 111, and the user can rotate the first pipe section 111 by applying a force to the second pipe section 112.

[0075] In some embodiments, there is a relatively large frictional force between the first pipe section 111 and the cabinet 2 (for example, the contact part between the first pipe section 111 and the cabinet 2 is made of a material with a relatively high coefficient of friction). When the user does not apply a force to the first pipe section 111, this frictional force serves to lock the first pipe section 111.

[0076] Refer to Figure 6 , in some embodiments, a mounting seat 4 is convexly provided on the outer side of the cabinet 2. The mounting seat 4 is disposed opposite to the outer side surface of the first pipe section 111. A wing screw 5 is threadedly connected to the mounting seat 4, and the first pipe section 111 is located on the moving path of the wing screw 5. After loosening the wing screw 5 and applying a force to the first pipe section 111, the first pipe section 111 can be rotated; after the first pipe section 111 is rotated by an appropriate angle so that the smoking port 1171 is in an appropriate position and orientation, the wing screw 5 is tightened, and the fixing of the first pipe section 111 can be achieved to prevent the first pipe section 111 from continuing to rotate and causing the smoking port 1171 to deviate from the appropriate position and orientation.

[0077] Preferably, the wing screw 5 is a wing screw with a flat bottom, that is, the wing screw 5 is a flat-bottom screw, which is beneficial to preventing damage to the first pipe section 111 after the wing screw 5 is tightened.

[0078] In some embodiments, the first pipe section 111 is slidably connected to the cabinet 2, which is beneficial to flexibly adjusting the position of the smoking port 1171. For example, in the Figure 1 illustrated embodiment, the first pipe section 111 can slide relative to the cabinet 2 along its own length direction (i.e., the Y direction).

[0079] Exemplarily, a portable power source / vehicle power source can be used to supply power to the cooking device.

[0080] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0081] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
