[0002] In order to meet consumers' demand for cooking food with a smoky flavor, cooking utensils with a smoking function have appeared on the market. Specifically, when cooking food, the smoking material is heated to generate smoke, which has a smoking effect on the food, giving the food a smoky flavor.

[0051] The embodiment of the present invention provides a vertical smoldering combustion assembly and a cooking device. The vertical smoldering combustion assembly facilitates the rapid disassembly and assembly of a combustion box and is easy to use.

[0052] The technical solution provided by the present invention is described in more detail below with reference to FIG1 to FIG13.

[0053] Embodiment 1:

[0054] The vertical smoldering combustion assembly provided by the present invention includes a cigarette lighter 1 and a combustion box 2 for containing smoking material, wherein: as shown in Figure 4, the bottom of the combustion box 2 is provided with an air inlet 23, and the upper part is provided with an air outlet 24 connected to the frying barrel, so that the air flow passes through the combustion box 2 from bottom to top, or, the upper part of the combustion box 2 is provided with an air inlet 23, and the bottom is provided with an air outlet 24 connected to the frying barrel, so that the air flow passes through the combustion box 2 from top to bottom; the cigarette lighter 1 is fixed in the shell of the cooking device, the cigarette lighter 1 is located outside the combustion box 2, and there is a horizontal distance between the cigarette lighter 1 and the bottom of the combustion box 2, or, at least a portion of the cigarette lighter 1 extends into the bottom of the combustion box 2, so that the smoking material vertically smolders from bottom to top in the combustion box 2.

[0055] In this embodiment, as shown in Figure 4, an air inlet 23 is provided at the bottom of the combustion box 2, and an air outlet 24 connected to the frying barrel is provided at the upper part thereof, so that the air flow passes through the combustion box 2 from bottom to top (this is the same direction smoldering), and the cigarette lighter 1 is fixed in the shell of the cooking device, and the cigarette lighter 1 is located outside the combustion box 2, and there is a horizontal distance between the cigarette lighter 1 and the bottom of the combustion box 2, or, at least a part of the cigarette lighter 1 extends into the bottom of the combustion box 2, so that the smoking material smolders vertically from bottom to top in the combustion box 2.

[0056] Alternatively, as an embodiment not shown, the bottom of the combustion box 2 is provided with an air inlet, and the upper part thereof is provided with an air outlet connected to the frying barrel, so that the air flow passes through the combustion box from top to bottom (this is reverse smoldering).

[0057] Among them, vertical smoldering refers to the burning of the smoke material from bottom to top, reverse smoldering refers to the flow direction of the airflow being opposite to the burning direction of the smoke material, and co-directional smoldering refers to the flow direction of the airflow being the same as the burning direction of the smoke material.

[0058] As shown in FIG12 , in the cooking device, a driving device 10 (motor), a first fan 8, and a heating element are disposed within a housing 6. The first fan 8 is located above the frying vat 5, and the driving device 10 (motor) is connected to the first fan 8 for driving the first fan 8 to rotate. The heating element is located between the first fan 8 and the frying vat 5 for heating the airflow circulating within the frying vat 5.

[0059] The driving device 10 can be a motor. The driving device 10 drives the first fan 8 to rotate, thereby generating an airflow. After the airflow passes through the heating unit 7, it becomes hot air. This hot air circulates in the frying vat 5, thereby heating the food in the frying vat 5. Referring to FIG. 12 , the direction of the curved arrow in FIG. 12 indicates the direction of the hot air flow.

[0060] Working principle:

[0061] The lighter rod 4 heats and carbonizes the incense burner through intermittent or contact heating. The controller controls the direction of the combustion-supporting airflow, such as the direction of rotation and speed of the motor, as well as the temperature of the lighter rod 4, to ensure that the direction of combustion is opposite or the same as the direction of combustion of the incense burner. Specifically, the counterclockwise rotation of the drive device 10 (motor) generates horizontal, reverse-flowing, high-temperature hot air. Combined with the control of the hot air velocity, this effectively controls the direction and speed of carbonization of the incense burner, ensuring a fully smoldering combustion of the incense burner and oxygen.

[0062] In this embodiment, a cigarette ignition rod 1 is provided to ignite the smoking material, and through effective control, the smoking material is put into a vertical smoldering state (smoldering is a relatively basic combustion phenomenon, which is a combustion reaction that occurs at the gas-solid interface but without the appearance of flame. The smoldering combustion process is relatively weak and can occur and be maintained in an environment with low temperature and low heat). The biomass particles in the smoldering state can produce enough smoke, thereby greatly improving the smoking effect of the food and satisfying consumers' demand for smoked food; in addition, the flow direction of the airflow is opposite to or the same as the combustion direction of the smoking material, further causing the biomass particles to enter a vertical reverse smoldering state or a vertical same-direction smoldering state (vertical reverse smoldering is manifested as the moving direction of the combustion reaction area is opposite to the moving direction of the airflow, etc., and due to the limitation of the air propagation speed, its combustion process propagates relatively slowly and requires less oxygen).

[0063] This cooking device uses the principle of vertical forward smoldering to burn the smoking material. By controlling the temperature and airflow speed, the smoking material is slowly and steadily smoldering vertically from bottom to top in the combustion box, which makes the smoking efficiency fast, extends the smoking time, and can generate enough smoke and heat, thereby achieving obvious smoking and heating effects. It is highly safe and provides a good user experience.

[0064] Specifically, the vertical smoldering combustion assembly also includes a thermostat 15 for detecting the temperature of the lighter rod 1. The temperature-sensing end of the thermostat 15 is connected to the lighter rod 1 via heat conduction. Heat generated by the lighter rod 1 is transferred to the temperature-sensing end of the thermostat 15 via a heat conductor, enabling the thermostat 15 to effectively detect the temperature of the lighter rod 1 and, in turn, monitor the temperature of the combustion chamber 2. The thermostat 15 is located in the circuit between the lighter rod 1 and the controller. By controlling the temperature of the lighter rod, the incense burner is kept smoldering or extinguished, while also preventing the smoldering burner from transitioning to an open flame.

[0065] The thermostat can be a snap-action thermostat or an electronic thermistor thermostat:

[0066] 1. Snap-action thermostat: When the temperature of the cigarette lighter rod 1 increases or decreases, the corresponding heat is transferred to the bimetallic disc of the snap-action thermostat. When the set operating temperature of the snap-action thermostat is reached, the snap-action thermostat quickly operates, opening or closing the contacts through the internal mechanical structure, thereby connecting or disconnecting the circuit, thereby controlling the circuit on and off. In the snap-action thermostat, the disc-shaped disc of bimetallic material acts as a temperature-sensing element (using the cover to transfer heat). When the temperature rises (or drops) to the operating temperature, it instantly produces a snap action. This action is transmitted to the elastic moving contact bracket by the ceramic operating rod. The moving contact and fixed contact are riveted to the moving contact bracket and the horn respectively. When the moving contact bracket is pushed by the operating rod, the moving contact and the fixed contact separate, thereby disconnecting the circuit. When the temperature drops to the recovery temperature of the disc-shaped bimetallic disc, the bimetal instantly returns to its original shape, the pressure applied to the operating rod is eliminated, and the moving contact and fixed contact return to their original shape, thereby connecting the circuit. Specifically, under normal working conditions, the thermostat is in a normally closed state, ensuring that the circuit between the lighter rod 1 and the controller is open and the lighter rod is heated normally; when the thermostat detects that the temperature of the lighter rod 1 exceeds about 140°C, the thermostat trips; when the lighter rod 1 stops heating, the thermostat detects that the temperature of the lighter rod 1 drops to about 120°C, at which point the thermostat closes again and the lighter rod 1 works again; the above actions are repeated; it can be seen that the controller can monitor the temperature of the lighter rod through the thermostat, and thus control the temperature inside the combustion box;

[0067] 2. Electronic thermistor thermostat: The electronic thermistor thermostat is installed near the cigarette lighter rod 1 to detect the temperature around the cigarette lighter rod 1. The specific working process is: detect the temperature around the cigarette lighter rod 1 → the electronic thermistor thermostat compares the temperature (comparing its own set temperature with the measured temperature) → the electronic thermistor thermostat calculates the output deviation → the controller controls the heating or disconnection operation amount, and the above working process is continuously cycled.

[0068] In addition to the above scheme of controlling the temperature by setting the thermostat, the following schemes are also available:

[0069] The controller is equipped with a timing module for recording time and a temperature control program for controlling the cigarette lighter rod 1. The temperature control program sets the heating time and cooling time. When the time recorded by the timing module reaches the heating time, the temperature control program controls the cigarette lighter rod 1 to be powered off. When the time recorded by the timing module reaches the cooling time, the temperature control program controls the cigarette lighter rod 1 to be powered on, achieving the heating or cooling effect. Specifically, the temperature control program is programmed with the heating time (the heating working time of the cigarette lighter rod 1) and the cooling time (the cooling stop time of the cigarette lighter rod 1). When the time recorded by the timing module reaches the heating time, the temperature control program sends a command to shut down the cigarette lighter rod 1, and the timing module starts recording the cooling time. When the time recorded by the timing module reaches the cooling time, the temperature control program sends a command to start the cigarette lighter rod 1, and the timing module restarts and records the heating time. The temperature control program controls based on the set time, so that the cigarette lighter rod 1 can continuously cycle within the set temperature range.

[0070] In this embodiment, a circuit program controls the rotation of the motor, driving the rotation of the first fan. The rotation of the first fan 8 exhausts air from the hollow portion of the housing (the frying tub), causing the air pressure in the hollow portion of the housing (the frying tub) to fall below the external ambient pressure, creating a negative pressure. This in turn generates a bottom-up airflow within the combustion box, driving the smoked material to smolder and causing the resulting smoke to flow into the hollow portion of the housing (the frying tub). The faster the motor rotates, the greater the air pressure in the hollow portion (the frying tub), resulting in a faster smoldering of the smoked material and a thicker smoke. By controlling the motor's rotation speed, the air pressure in the hollow portion (the frying tub) can be controlled, further controlling the smoldering duration of the smoked material and the amount of smoke produced to achieve the desired smoking effect for various ingredients.

[0071] As an optional embodiment, referring to Figures 3 and 4, the vertical smoldering combustion assembly of this embodiment also includes a fixed shell 4, which is fixedly connected to the shell 6 of the cooking device, and the cigarette lighter 1 is fixed to the concave side of the fixed shell 4; the fixed shell 4 is fixedly arranged in the shell 6, and the two sides of the cigarette lighter 1 are fixed to the opposite sides of the fixed shell 4. The fixed shell 4 and the electric cigarette stick do not move with the frying barrel 5. Referring to Figure 2, when the frying barrel 5 is pulled out, the combustion box 2 is taken out accordingly, and the fixed shell 4 and the cigarette lighter 1 are fixed in the shell 6.

[0072] The cigarette lighter rod 1 can be located at the top, bottom or side of the combustion box 2, as shown in Figures 3 and 6. In this embodiment, the cigarette lighter rod 1 is located at the side of the combustion box 2, and the smoking material in the combustion box 2 is ignited by intermittent heating. The above structure makes it easy to remove and disassemble the combustion box 2 along with the frying barrel 5.

[0073] As shown in FIG4 , the combustion box 2 is detachably connected to the side of the frying vat 5 away from the handle.

[0074] As shown in Figure 4, when the frying bucket 5 is inserted into the shell 6 of the cooking device, the combustion box 2 extends into the fixed shell 4, and there is a gap between the combustion box 2 and the fixed shell 4, thereby forming an air inlet channel 100 between the two; the cigarette lighter 1 and the air inlet 23 are arranged opposite to each other, and there is a distance between the two.

[0075] The structure in which the cigarette lighter rod 1 and the air inlet 23 are arranged opposite to each other facilitates high-temperature air to directly enter the combustion box 2 through the air inlet 23, thereby heating the smoking material and improving the utilization rate of heat.

[0076] In the above structure, the lighter rod 1 does not need to be taken out, and after the frying barrel 5 is inserted into the shell 6 and is in place, since there is a gap between the lighter rod 1 and the combustion box 2, compared with the structure in which the lighter rod 1 is inserted into the combustion box 2, it is convenient for the lighter rod 1 and the combustion box 2 to be aligned, preventing the lighter rod 1 and the combustion box 2 from not being properly docked and affecting the normal insertion of the frying barrel 5.

[0077] As shown in Figure 4, the direction of the arrow in Figure 4 represents the direction of air flow. The outside air can enter the combustion box 2 through the air inlet channel 100 and the air inlet 23, which makes it easier for the smoking material in the combustion box 2 to contact with the air and burn, and the smoke can flow into the frying barrel 5 from the air outlet 24, thereby greatly improving the smoking effect of the food and meeting consumers' demand for smoked food.

[0078] As an optional embodiment, referring to Figure 6, the combustion box 2 includes a box body 21 and an upper cover 22, the box body 21 and the upper cover 22 are detachably connected, the air inlet 23 and the air outlet 24 are respectively located on opposite sides of the box body 21, and the side of the upper cover 22 extends out of the side wall of the box body 21 for extending into the fixed shell 4.

[0079] The box body 21 and the upper cover 22 can be detachably connected by screws, bolts, etc. After the combustion box 2 is removed from the frying vat 5, the upper cover 22 and the box body 21 are disassembled to facilitate loading the smoking material into the combustion box 2. Alternatively, the combustion box 2 can be directly replaced with a new one.

[0080] The above structure of the upper cover 22 is such that the side of the upper cover 22 extends out of the side wall of the box body 21 and into the fixed shell 4, as shown in FIG. 4 , so as to facilitate the positioning of the combustion box 2 and the fixed shell 4.

[0081] As an optional embodiment, referring to Figures 6 and 4, a bending portion 20 is provided on the side of the burning box facing the lighter rod 1, the bending portion 20 protrudes toward the inner side of the burning box 2, and the air inlet 23 is located on the bending portion 20; a grille plate 26 is provided in the burning box 2, and the grille plate 26 divides the inner cavity of the burning box 2 into two upper and lower parts that are interconnected.

[0082] 4 , the ashes from the burning of the smoking material can be guided by the bent portion 20 and fall into the bottom of the combustion box 2 through the grid plate 26 , preventing the ashes from flowing out of the combustion box 2 and then into the fixed shell 4 and the shell 6 of the cooking device.

[0083] Example 2:

[0084] This embodiment provides another specific implementation of the combustion box:

[0085] As shown in Figures 10 and 11, the position and number of the insertion parts on the mounting member are arranged in a one-to-one correspondence with the receiving grooves; the notch of one of the receiving grooves is arranged downward, and the upper end of the receiving groove is a closed structure; a slide groove 27 is provided at the lower part of the combustion box, and the notch of the slide groove 27 is connected to the bottom end of the combustion box, and a buckle 32 is provided on the mounting member. When the buckle 32 extends into the slide groove 27, it pushes the combustion box 2, and the buckle 32 slides relative to the slide groove 27 until the insertion part 31 is plugged into place in the receiving groove 25.

[0086] As shown in FIG11 , a positioning groove 28 is provided on the side of the combustion box, and a protrusion is provided on the mounting member 3 . The protrusion 28 extends into the positioning groove 28 , which can further position the mounting member 3 and the combustion box.

[0087] In this embodiment, as shown in FIG. 10 , the buckle 32 extends into the slide groove 27 and pushes the combustion box in the direction of the arrow, which facilitates quick installation of the combustion box 2 and the mounting member 3 on the frying tub, making installation of the combustion box 2 more convenient.

[0088] Example 3:

[0089] Conventional cooking appliances with a smoking function typically include a combustion box for holding a combustible material, which is fixed to the cooking appliance. After the combustible material in the conventional combustion box is burned, the combustion box must be removed from the cooking appliance. This requires disassembly of multiple components, making assembly and disassembly of the combustion box complex and resulting in a poor user experience.

[0090] In response to the above problems, referring to Figures 2 to 8, this embodiment provides a vertical smoldering combustion assembly, a cigarette lighter 1 and a combustion box 2, wherein: referring to Figures 3, 4, 6 and 7, the combustion box 2 is provided with an air inlet 23 and an air outlet 24 connected to the frying barrel 5, the combustion box is used to hold smoking material and is connected to the air inlet 23 and the air outlet 24; one of the outer wall of the frying barrel 5 and the combustion box 2 is provided with an insertion portion 31, and the other is provided with a receiving groove 25, the insertion portion 31 can be extended into the receiving groove 25, thereby detachably connecting the frying barrel 5 to the combustion box 2; the cigarette lighter 1 is fixed in the shell 6 of the cooking device, and when the frying barrel 5 is installed in the shell 6 of the cooking device, the cigarette lighter 1 is located outside the combustion box 2 or at least partially extends into the combustion box 2, thereby making the smoking material smolder.

[0091] Among them, the smoking material of this embodiment can be biomass particles, etc., which are granular mixtures made from a mixture of multiple woods. The mixed woods include one or more of walnut, mesquite, apple, cherry, oak, hickory, maple, alder, etc., which are more environmentally friendly.

[0092] 1 to 12 , an air fryer is used as an example of a cooking device in this embodiment.

[0093] 3 and 4 , in this embodiment, the inserting portion 31 is located on the frying tub 5 , and the receiving groove 25 is located on the combustion box 2 . Of course, the inserting portion 31 may also be located on the combustion box 2 , and the receiving groove 25 may be located on the frying tub 5 .

[0094] In the vertical smoldering combustion assembly of this embodiment, when the smoking material in the combustion box 2 needs to be replaced, the frying barrel 5 can be directly pulled out from the shell 6 of the cooking device, and the combustion box 2 can be pulled up to separate the insertion portion 31 from the receiving groove 25, and the combustion box 2 can be separated from the frying barrel 5 and replaced with a new combustion box 2, or new smoking material can be loaded into the combustion box 2, and the insertion portion 31 can be reinserted into the receiving groove 25, and the combustion box 2 can be quickly assembled on the frying barrel 5 and loaded into the frying barrel 5.
