Description

Technical Field

[0001] The present invention belongs to the field of outdoor products, and particularly relates to an outdoor barbecue grill. Background Art

[0002] An outdoor barbecue grill is a cooking utensil for grilling and cooking barbecue food with charcoal fire outdoors. In outdoor barbecue, the ventilation of the barbecue cavity is the core control factor for the combustion of barbecue charcoal, which directly affects the combustion efficiency, temperature stability and cooking effect. Although the existing outdoor barbecue grills are provided with air inlets and air outlets, they rely on natural blowing or manual air supply, and it is easy to have the situation of insufficient charcoal combustion in a weak wind environment or single-person operation, which affects the cooking efficiency. Summary of the Invention

[0003] In view of the above problems, the embodiments of the present application provide an outdoor barbecue grill, which can reduce the risk of insufficient charcoal combustion in a weak wind environment or single-person operation.

[0004] The embodiments of the present application provide an outdoor barbecue grill, which includes a main body and a connecting member. The main body internally has a first cavity, a second cavity and a third cavity arranged in sequence along the gravity direction. The main body has a first air inlet and an exhaust port that are internally communicated with the first cavity. The first cavity is used for placing combustibles and is located above the second cavity. The second cavity is used for accommodating a first liquid, and the first liquid is used for absorbing the heat of the first cavity to vaporize. The second cavity has a first wall far away from the first cavity, and the first wall is made of a flexible material. When the first liquid vaporizes, the first wall deforms towards the direction close to the third cavity to compress the third cavity. The third cavity is externally communicated, and a second liquid is arranged in the third cavity. The second liquid is used for absorbing the heat in the second cavity when abutting against the first wall; the connecting member is used for communicating the third cavity and the first air inlet.

[0005] Specifically, the first chamber is used to place the combustible material and for the combustion of the combustible material. During this period, the combustible material burns and releases heat. Most of the heat released by the combustible material is used to barbecue the food placed outside the first chamber, and part of the heat is used to heat the first liquid in the second chamber to vaporize the first liquid, thereby increasing the pressure in the second chamber, and then causing the first wall to deform towards the third chamber to compress the third chamber, and causing the gas in the third chamber to move towards the first air inlet through the connecting member to supply air to the first chamber to enable the combustible material to burn sufficiently. During this period, the second liquid no longer contacts the wall of the second chamber close to the first chamber, reducing the heat absorption efficiency of the second liquid, and causing the first wall to contact the second liquid, so that the second liquid absorbs the heat of the first liquid, thereby liquefying the gas generated by the vaporization of the first liquid in the second chamber, and then reducing the pressure in the second chamber, so that the first wall deforms in the direction of increasing the volume of the third chamber, facilitating the entry of external air into the third chamber, and enabling the first liquid to continue to contact the wall of the second chamber close to the first chamber, so that the first liquid can continue to absorb the heat in the first chamber.

[0006] In the above technical solution, the third chamber is repeatedly squeezed by the first wall to drive air to enter the first chamber from the third chamber, so as to increase the air content in the first chamber, thereby reducing the risk of incomplete combustion of the combustible material.

[0007] In some embodiments, the outdoor barbecue grill further includes a one-way valve, and the one-way valve is arranged on the body, and the one-way valve is used for allowing air to move from the outside to the third chamber.

[0008] In the above technical solution, the one-way valve restricts the gas in the third chamber from discharging to the outside, so as to increase the amount of air entering the first chamber from the third chamber, and further reduce the risk of incomplete combustion of the combustible material.

[0009] In some embodiments, a first air passage is arranged in the connecting member, and the first air passage has a first end and a second end arranged oppositely. The first end is communicated with the third chamber, and the second end is communicated with the first air inlet.

[0010] In the above technical solution, by arranging the first air passage to connect the first air inlet and the third chamber, the structure is simple and easy to implement.

[0011] In some embodiments, a second air passage and a third air passage are further arranged in the connecting member. One end of the second air passage is communicated with the first air passage, and the distance between the axis of the second air passage and the axis of the first air passage gradually decreases along the direction from the first end to the second end; one end of the third air passage is communicated with the first air passage, and the distance between the axis of the third air passage and the axis of the first air passage gradually decreases along the direction from the first end to the second end, and the other end of the third air passage is communicated with the other end of the second air passage.

[0012] Specifically, when air moves from the first end to the second end, since the distance between the axis of the second air passage and the axis of the first air passage gradually decreases in the direction from the first end to the second end, and the distance between the axis of the third air passage and the axis of the first air passage also gradually decreases in the direction from the first end to the second end. Therefore, when air moves along the first air passage towards the first cavity, it is not easy to enter the second air passage and the third air passage, so that the air directly moves from the first end of the first air passage towards the second end close to the first air passage. When air moves from the second end to the first end, since the distance between the axis of the second air passage and the axis of the first air passage gradually decreases in the direction from the first end to the second end. Therefore, it is easier for air to enter the second air passage from one end close to the second end of the second air passage, and return to the first air passage from the other end far from the second end of the third air passage, and convect with the air originally flowing in the first air passage towards the first end. Thus, the movement of air in the first air passage from the second end to the first end is slowed down.

[0013] In this way, when the volume of the third cavity decreases, air can quickly move towards the first cavity, and when the volume of the third cavity increases, the movement of air from the first cavity to the third cavity is restricted. On the one hand, it can reduce the transfer of heat from the first cavity to the third cavity, lower the temperature of the second liquid, and facilitate the second liquid to absorb the heat in the second cavity. On the other hand, it reduces the risk of incomplete combustion of the combustible due to the third cavity repeatedly supplying air with low oxygen content to the first cavity.

[0014] In some embodiments, there are multiple second air passages and multiple third air passages, and the multiple second air passages and the multiple third air passages are alternately distributed on opposite sides of the first air passage along the axis of the first air passage in sequence.

[0015] In the above technical solution, the multiple second air passages and the multiple third air passages are alternately distributed on opposite sides of the first air passage along the axis of the first air passage in sequence, thus making full use of the space inside the connector.

[0016] In some embodiments, the first air passage includes multiple sub-passages, the multiple sub-passages are connected in sequence, and the multiple sub-passages correspond one-to-one to the multiple second air passages and the multiple third air passages; wherein, the sub-passages, the second air passages and the third air passages enclose a circuit, and the second air passage and the sub-passage adjacent in the direction from the second end to the first end are coaxial.

[0017] In the above technical solution, the second air passage and the sub-passage adjacent in the direction from the second end to the first end are coaxial, so that when air moves from the second end to the first end, it is convenient for air to enter the second air passage, thereby strengthening the ability of the connector to restrict the movement of air from the first cavity to the third cavity.

[0018] In some embodiments, the body includes a first housing, a second housing, and a third housing arranged in sequence along the direction of gravity. The first chamber is located within the first housing, the second chamber is located within the second housing, and the second housing and the third housing enclose to form the third chamber. Among them, the first housing and the second housing are detachably connected, and the second housing and the third housing are detachably connected.

[0019] In the above technical solution, the first housing and the second housing are detachably connected, and the second housing and the third housing are detachably connected, so as to facilitate the disassembly and assembly of the body and facilitate the assembly and handling of the outdoor barbecue grill.

[0020] In some embodiments, the second housing further includes a side wall surrounding the first wall, and the side wall is made of a heat-insulating material.

[0021] In the above technical solution, the side wall is made of a heat-insulating material to facilitate reducing the movement of the heat in the first chamber to the third chamber through the side wall.

[0022] In some embodiments, the body has a second air inlet communicating with the interior of the first chamber. The second air inlet communicates with the outside, and the second air inlet is located above the first air inlet.

[0023] In the above technical solution, the second air inlet is located above the first air inlet. Thus, when the first air inlet intakes air into the first chamber, the gas entering the first chamber through the first air inlet can remove the sundries (such as the dust after combustion) below the second air inlet, thereby reducing the risk of the second air inlet being blocked in a weak wind environment.

[0024] In some embodiments, the first chamber has a second wall away from the second chamber, and a hollowed-out portion is provided on the second wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0031] An outdoor barbecue grill is a cooking utensil for grilling and cooking barbecue food with charcoal outdoors. Ventilation of the barbecue cavity is the core control factor for the combustion of barbecue charcoal in outdoor barbecues, which directly affects the combustion efficiency, temperature stability, and cooking effect. Although intake ports and outlet ports are provided on outdoor barbecue grills in the prior art, they rely on natural blowing for intake or manual air supply, and it is easy to have the situation of incomplete combustion of charcoal in a weak wind environment or during single-person operation, affecting the cooking efficiency.

[0032] To solve the above technical problems, referring to Figure 1 and Figure 2, an embodiment of the present application provides an outdoor grill including a main body 10 and a connecting member 20. The main body 10 has a first chamber 101, a second chamber 102, and a third chamber 103 arranged in sequence along the direction of gravity. The main body 10 has a first air inlet 1011 and an exhaust port that communicate with the inside of the first chamber 101. The first chamber 101 is used to place combustibles and is located above the second chamber 102. The second chamber 102 is used to accommodate a first liquid, and the first liquid is used to absorb the heat of the first chamber 101 to vaporize. The second chamber 102 has a first wall 121 away from the first chamber 101, and the first wall 121 is made of a flexible material. When the first liquid vaporizes, the first wall 121 deforms towards the third chamber 103 to compress the third chamber 103. The third chamber 103 communicates with the outside, and a second liquid is provided in the third chamber 103. The second liquid is used to absorb the heat in the second chamber 102 when it abuts against the first wall 121; the connecting member 20 is used to connect the third chamber 103 and the first air inlet 1011.

[0033] Exemplarily, the wall separating the first chamber 101 and the second chamber 102 can be made of a metal material.

[0034] The first wall 121 can be made of a flexible material such as silicone rubber.

[0035] Specifically, the first chamber 101 is used to place combustibles and for the combustion of the combustibles. During this period, the combustibles burn and release heat. Most of the heat released by the combustibles is used to grill the food placed outside the first chamber 101, and part of the heat is used to heat the first liquid in the second chamber 102 to vaporize the first liquid. As a result, the pressure in the second chamber 102 increases, and then the first wall 121 deforms towards the third chamber 103 to compress the third chamber 103, and the gas in the third chamber 103 moves through the connecting member 20 towards the first air inlet 1011 to supply air into the first chamber 101 to enable the combustibles to burn fully. During this period, the second liquid no longer contacts the wall of the second chamber 102 close to the first chamber 101, reducing the heat absorption efficiency of the second liquid, and the first wall 121 contacts the second liquid so that the second liquid absorbs the heat of the first liquid, and then the gas generated by the vaporization of the first liquid in the second chamber 102 liquefies, and then the pressure in the second chamber 102 decreases, causing the first wall 121 to deform in the direction of increasing the volume of the third chamber 103 to facilitate the entry of outside air into the third chamber 103 and enable the first liquid to continue to contact the wall of the second chamber 102 close to the first chamber 101 to facilitate the first liquid to continue to absorb the heat in the first chamber 101.

[0036] In this technical solution, the first wall 121 repeatedly squeezes the third chamber 103 to drive air to enter the first chamber 101 from the third chamber 103, increasing the air content in the first chamber 101, thereby reducing the risk of incomplete combustion of the combustibles.

[0037] According to some embodiments of the present application, the outdoor barbecue grill further includes a one-way valve 30. The one-way valve 30 is disposed on the main body 10 and is used for allowing air to move from the outside to the third chamber 103.

[0038] Exemplarily, the one-way valve 30 is a general gas one-way valve 30, which is a prior art.

[0039] In this technical solution, the one-way valve 30 restricts the gas in the third chamber 103 from being discharged to the outside, so as to increase the amount of air entering the first chamber 101 from the third chamber 103, thereby further reducing the risk of incomplete combustion of the combustible.

[0040] According to some embodiments of the present application, a first air passage 21 is provided in the connector 20. The first air passage 21 has a first end 21A and a second end 21B which are oppositely arranged. The first end 21A communicates with the third chamber 103, and the second end 21B communicates with the first air inlet 1011.

[0041] In this technical solution, the structure of connecting the first air inlet 1011 and the third chamber 103 by providing the first air passage 21 is simple and easy to implement.

[0042] According to some embodiments of the present application, a second air passage 22 and a third air passage 23 are further provided in the connector 20. One end of the second air passage 22 communicates with the first air passage 21, and the distance between the axis of the second air passage 22 and the axis of the first air passage 21 gradually decreases along the direction from the first end 21A to the second end 21B; one end of the third air passage 23 communicates with the first air passage 21, and the distance between the axis of the third air passage 23 and the axis of the first air passage 21 gradually decreases along the direction from the first end 21A to the second end 21B. The other end of the third air passage 23 communicates with the other end of the second air passage 22.

[0043] Specifically, when air moves from the first end 21A to the second end 21B, since the distance between the axis of the second air passage 22 and the axis of the first air passage 21 gradually decreases in the direction from the first end 21A to the second end 21B, and the distance between the axis of the third air passage 23 and the axis of the first air passage 21 also gradually decreases in the direction from the first end 21A to the second end 21B. Therefore, when air moves along the first air passage 21 towards the direction close to the first chamber 101, it is not easy to enter the second air passage 22 and the third air passage 23, so that the air directly moves from the first end 21A of the first air passage 21 towards the second end 21B close to the first air passage 21. When air moves from the second end 21B to the first end 21A, since the distance between the axis of the second air passage 22 and the axis of the first air passage 21 gradually decreases in the direction from the first end 21A to the second end 21B. Therefore, air is more likely to enter the second air passage 22 from one end close to the second end 21B of the second air passage 22, and return to the first air passage 21 from the other end far from the second end 21B of the third air passage 23, and generate convection with the air originally flowing in the first air passage 21 towards the first end 21A. Thus, the movement of air in the first air passage 21 along the second end 21B to the first end 21A is slowed down.

[0044] In this way, when the volume of the third chamber 103 decreases, air can quickly move towards the first chamber 101. When the volume of the third chamber 103 increases, the movement of air from the first chamber 101 to the third chamber 103 is restricted. On the one hand, it can reduce the transfer of heat from the first chamber 101 to the third chamber 103, lower the temperature of the second liquid, and facilitate the second liquid to absorb the heat in the second chamber 102. On the other hand, it reduces the risk of incomplete combustion of the combustible due to the third chamber 103 repeatedly supplying air with low oxygen content to the first chamber 101.

[0045] According to some embodiments of the present application, there are multiple second air passages 22 and multiple third air passages 23. The multiple second air passages 22 and the multiple third air passages 23 are alternately distributed on opposite sides of the first air passage 21 along the axis of the first air passage 21 in sequence.

[0046] In this technical solution, the multiple second air passages 22 and the multiple third air passages 23 are alternately distributed on opposite sides of the first air passage 21 along the axis of the first air passage 21 in sequence, so as to make full use of the space inside the connecting member 20.

[0047] According to some embodiments of the present application, the first air passage 21 includes multiple sub - passages 211. The multiple sub - passages 211 are connected in sequence. The multiple sub - passages 211 correspond one by one to the multiple second air passages 22 and the multiple third air passages 23. Among them, the sub - passage 211, the second air passage 22 and the third air passage 23 enclose a loop, and the second air passage 22 and the sub - passage 211 adjacent in the direction from the second end 21B to the first end 21A are co - axial.

[0048] In the present technical solution, the second air passage 22 and the sub-passage 211 adjacent in the direction from the second end 21B to the first end 21A are coaxial, so that when air moves from the second end 21B to the first end 21A, it is convenient for the air to enter the second air passage 22, thereby enhancing the ability of the connecting member 20 to restrict the movement of air from the first chamber 101 to the third chamber 103.

[0049] According to some embodiments of the present application, the body 10 includes a first housing 11, a second housing 12, and a third housing 13 arranged in sequence along the gravity direction. The first chamber 101 is located in the first housing 11, the second chamber 102 is located in the second housing 12, and the second housing 12 and the third housing 13 enclose and form the third chamber 103. Among them, the first housing 11 and the second housing 12 are detachably connected, and the second housing 12 and the third housing 13 are detachably connected.

[0050] In the present technical solution, the first housing 11 and the second housing 12 are detachably connected, and the second housing 12 and the third housing 13 are detachably connected, so as to facilitate the disassembly and assembly of the body 10, and facilitate the assembly and handling of the outdoor barbecue grill.

[0051] According to some embodiments of the present application, the second housing 12 further includes a side wall 122 surrounding the first wall 121, and the side wall 122 is made of a heat-insulating material.

[0052] Exemplarily, the side wall 122 can be made of a ceramic material.

[0053] In the present technical solution, the side wall 122 is made of a heat-insulating material, so as to reduce the movement of the heat of the first chamber 101 to the third chamber 103 through the side wall 122.

[0054] According to some embodiments of the present application, the body 10 has a second air inlet 1012 communicating with the inside of the first chamber 101. The second air inlet 1012 communicates with the outside, and the second air inlet 1012 is located above the first air inlet 1011.

[0055] In the present technical solution, the second air inlet 1012 is located above the first air inlet 1011. Thus, when the first air inlet 1011 intakes air into the first chamber 101, the gas entering the first chamber 101 through the first air inlet 1011 can remove the debris (such as the dust after combustion) below the second air inlet 1012, thereby reducing the risk of blockage of the second air inlet 1012 in a weak wind environment.

[0056] According to some embodiments of the present application, the first chamber 101 has a second wall away from the second chamber 102, and a hollowed-out portion is provided on the second wall.

[0057] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0058] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
