Detailed Implementation

[0033] To enhance understanding of this utility model, it will be further described in detail below with reference to embodiments and accompanying drawings. This utility model can be implemented in the following ways:

[0034] Reference Figure 1-6 A cabinet-type smokehouse with multiple heating modes includes a furnace body 1. Inside the furnace body 1 are a smoking chamber 2 and a pellet feeding mechanism 3. The smoking chamber 2 is mainly used to hold the food to be smoked. A chimney 4 connected to the smoking chamber 2 is located at the top of the furnace body 1. A heating element 5 and a pellet smoke burner 6 are located at the bottom of the smoking chamber 2. A controller 7 electrically connected to the pellet smoke burner 6 and the heating element 5 is located outside the furnace body 1. The controller 7 allows switching between three smoking modes: electric smoking, pellet smoking, and combined smoking. Furthermore, the combined smoking mode can achieve synergistic effects between two heating methods, making it widely applicable.

[0035] The bottom of the furnace body 1 is equipped with a forced convection fan 8, which is a dual-axis turbine fan. In this embodiment, the heating element 5 has a power of 1500W. The fan 8 is positioned below the pellet smoke burner 6, ensuring complete combustion. When the fan 8 is turned on, air blows from the bottom of the furnace body 1 into the smoking chamber 2, and then exits from the chimney 4 at the top of the furnace body 1. This forces the hot air, smoke, and steam inside the furnace to circulate evenly, ensuring uniform heating and smoking of the food.

[0036] To increase the volume of the pellet feeding mechanism 3 and ensure a continuous supply of fuel to the pellet smoke burner 6, the pellet feeding mechanism 3 is located at the rear of the smoking chamber 2. The pellet feeding mechanism 3 includes a pellet bin 31, a feeding flap 32 on top of the pellet bin 31, and a discharge port 33 on the bottom side of the pellet bin 31. The pellet bin 31 extends from the top to the bottom of the furnace body 1, providing a large storage volume. When feeding is needed, the feeding flap 32 is opened to add fuel; when cleaning the pellet bin 31 is required, the discharge port 33 is opened to discharge all the pellets from the pellet bin 31, making the operation simple and quick.

[0037] In this embodiment, the pellet smoke burner 6 includes a quantitative feeder 61 connected to the pellet feeding mechanism 3, an ignition rod 62 located below the quantitative feeder 61, and a combustion cup 63 connected to the smoking chamber 2. The quantitative feeder 61 is located below the pellet bin 31. The quantitative feeder 61 includes a feeding motor 611 and a quantitative feeding screw 612 movably connected to the feeding motor 611. The feed end of the quantitative feeding screw 612 is connected to the pellet bin 31, and the discharge end is connected to the combustion cup 63. In this embodiment, the quantitative feeding is achieved by driving the quantitative feeding screw 612 back and forth through the feeding motor 611. Specifically, the controller 7 feeds according to different preset speeds, i.e., the program for each speed is set with a feeding time of a certain number of seconds, a pause time of a certain number of seconds, and then feeding again, thereby achieving the purpose of quantitative feeding at each speed. A protective cover 64 is provided above the combustion cup 63, and an air outlet 641 is provided on the side of the protective cover 64. When the pellets in the pellet bin 31 are fed into the combustion cup 63 by the metering screw 612, the ignition rod 62 instantly ignites the pellets. The hot air generated by the burning of the pellets in the combustion cup 63 will be discharged outward through the air outlet 641 of the protective cover 64, which can prevent the high temperature flame from being directly sprayed onto the food surface.

[0038] A drawer-type spice box 9 is provided above the heating tube 5. The drawer-type spice box 9, positioned above the heating tube 5, ensures that the spices within are heated evenly, resulting in uniform smoke generation. Specifically, the drawer-type spice box 9 includes a drawer box 91 with an upper opening for holding spices, a support box 92 for supporting the drawer box 91, and a connector 93 for fixing the support box 92 within the furnace body 1. A support member 94 for supporting the heating tube 5 is provided at the bottom of the support box 92. The support box 92 has a front opening 921 into which the drawer box 91 is inserted. Several smoke outlet holes 922 are provided on the top edges of the two long sides of the support box 92. Smoke generated by the spices can only be discharged through the smoke outlet holes 922, thus achieving dual-channel smoke generation from the spice box and increasing the flavor substance release rate by 40%. One end of the drawer box 91 is provided with a handle 95 for easy pulling out. The stove body 1 is provided with a drawer opening for the drawer box 91 to be inserted at the corresponding position of the drawer-type spice box 9. The handle 95 is provided with a baffle 96 that completely covers the drawer opening at the end that contacts the stove body 1, which can ensure that the smoke will not leak out.

[0039] In addition, a temperature probe 21 is installed inside the smoking chamber 2 to monitor the temperature inside the chamber in real time. Combined with a PID algorithm, this allows for precise temperature control, achieving a temperature control error within ±2℉. A flame sensor 22 is also installed inside the smoking chamber 2. The flame sensor 22 is electrically connected to the controller 7. When the controller 7 receives an abnormal signal from the flame sensor 22, it will control the heating element 5 and the particulate smoke burner 6 to stop operating, thereby achieving safety protection.

[0040] This embodiment can implement the following three modes, the specific modes are as follows:

[0041] 1. Mode 1 (Pure Electric Smoke)

[0042] o 1500W heating element 5 is working, bottom fan 8 is turned on for forced convection;

[0043] o Drawer-type spice box 9 is placed above heating tube 5 to achieve uniform smoke generation;

[0044] Temperature probe 21 monitors the temperature of the smoking chamber 2 in real time (90-275℉);

[0045] o PID algorithm for precise temperature control, with an error of ±2℉.

[0046] 2. Mode 2 (Pure Granular Smoke)

[0047] The feed screw 612 feeds the material, and the ignition rod 62 ignites the pellets instantly.

[0048] o Turn on the dual-shaft turbo fan 8 to ensure complete combustion;

[0049] The high-temperature range reaches 450℉, suitable for rapid baking;

[0050] oActivate the flame sensor 22 linkage safety protection device.

[0051] 3. Mode 3 (Combined Smoke)

[0052] The heating element 5 is reduced to 400W for auxiliary heating;

[0053] o A hybrid mode of main heating by particle combustion + electric heating compensation;

[0054] The dual-channel smoke generation of the spice box increases the release rate of flavor substances by 40%.

[0055] The temperature control system automatically balances the output of the two heat sources.

[0056] Examples of specific use cases:

[0057] 1. Low-temperature slow roasting scenario: Select mode 1 and set it to 120℉; after preheating heating element 5 to 100℉, put in the ingredients; add apple wood chips to the spice box, and the smoke generation time is adjustable.

[0058] 2. High-temperature rapid baking scenario: Switch to mode 2 and set to 400℉; the pellet combustion chamber will automatically ignite and reach the set temperature within 3 minutes; the high-temperature section will be maintained for 15 minutes to achieve surface caramelization.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
