Description

Technical Field

[0001] This application relates to the field of oven technology, specifically to an oven based on smoke baking. Background Technology

[0002] Ovens are basically divided into two categories: one is modern electric or natural gas ovens, and the other is traditional fuel (wood, coal, straw, etc.) ovens. Modern ovens have many advantages, but when baking traditional flavored foods, they cannot reproduce the original smoky aroma of traditional flavored foods, and the flavor and taste of the food are greatly reduced. Therefore, many businesses still use traditional ovens to make flavored foods.

[0003] The prior art discloses an oven with adjustable charcoal fire height, including an oven body. The top of the oven body is equipped with a dual-use charcoal and gas oven device. The oven device includes a lower support plate fixed to the top of the oven body, a gas oven and a charcoal oven fixed to the top of the lower support plate, and an upper support plate fixed to the top of the gas oven and the charcoal oven. The upper support plate is equipped with two sets of three-dimensional double-layer grilling mesh mechanisms located on the gas grilling area and the charcoal grilling area respectively. The three-dimensional double-layer grilling mesh mechanism includes a grilling mesh and a heat-insulating mesh on the grilling mesh. The gas oven is equipped with a gas grilling mesh, and the charcoal oven is equipped with a lifting charcoal grilling tray mechanism.

[0004] While some existing ovens can use traditional fuels (such as wood, coal, and straw) to bake flavorful foods, their design is not ideal. The fuel burns inside the oven chamber, and the combustion flue gas directly heats the baking tray. Due to the lack of flue gas guidance in the oven cavity, the flue gas rises straight up and is discharged from the chimney. This design results in high flue gas temperature and low utilization of waste heat, leading to low fuel utilization and significant energy waste. Utility Model Content

[0005] Therefore, this application provides an oven based on flue gas baking to solve the problem that the existing technology lacks guidance for flue gas in the oven cavity, causing the flue gas to rise directly upward and be discharged from the chimney. With this design, the discharged flue gas temperature is high, the utilization rate of flue gas waste heat is low, and thus the fuel utilization rate is low, resulting in a large amount of energy waste.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An oven based on flue gas baking, mainly used for baking traditional flavored foods, specifically includes a box body, a combustion chamber at the lower end of the box body, a chimney connected to the inner cavity at the upper end of the box body, multiple baffles installed in the middle of the inner cavity of the box body, the multiple baffles being staggered on the inner walls of both sides of the box body to form a serpentine flue, and each baffle is provided with a movable baking tray that can be pulled out of the box body.

[0008] Optionally, the upper surface of the box has a baking area, and a baking tray cover is installed over the baking area. The baking tray cover includes a fixed cover and a movable cover. The fixed cover is fixed to the upper surface of the box, and the movable cover is hinged to the upper surface of the box and movably fitted outside the fixed cover. The movable cover can rotate toward the opening of the fixed cover and seal the opening.

[0009] Optionally, the inside of the baffle plate has a slot adapted to the movable baking tray. The front of the slot is set as an opening and connected to the outside of the box. The rear end of the movable baking tray is inserted into the baffle plate through the slot, and the front end of the movable baking tray seals the opening of the slot.

[0010] Optionally, a thermometer located below the movable baking tray is installed on the front of the baffle plate, and the temperature reading area of ​​the thermometer is located on the front of the box.

[0011] Optionally, the side of the housing has a cleaning port, and the number of cleaning ports is multiple and evenly distributed along the height direction of the housing.

[0012] Optionally, a guide block is installed on one side of the inner wall of the bottom of the box cavity. The guide block is opposite to the other side of the inner wall of the bottom of the box cavity to form a combustion chamber. There is a gap between the upper end face of the guide block and the lower end face of the adjacent guide plate to form the smoke inlet of the serpentine flue.

[0013] Optionally, the front of the combustion chamber is configured as an opening and connected to the outside of the housing. A grate is installed inside the combustion chamber, and an ash collection tray that can be moved outward is provided below the grate.

[0014] Optionally, the front of the housing is equipped with slide rails located above and below the combustion chamber opening, and a baffle for sealing the combustion chamber opening is installed between the two slide rails. The size of the combustion chamber opening and its opening / closing state can be adjusted by moving the baffle horizontally.

[0015] Optionally, a heat-conducting mechanism is installed at the bottom of the baffle plate. The heat-conducting mechanism is disposed in the serpentine flue to absorb the heat of the flue gas in the flue and conduct heat to the bottom of the movable baking pan.

[0016] Optionally, the heat conduction mechanism includes a heat conduction plate and heat conduction fins. The heat conduction plate is embedded in the bottom of the guide plate, and the heat conduction fins are installed at the bottom of the heat conduction plate and extend into the serpentine flue. The number of heat conduction fins is multiple and they are evenly distributed along the width direction of the serpentine flue.

[0017] Compared with the prior art, this application has at least the following beneficial effects:

[0018] By installing multiple baffles inside the chamber to form a serpentine flue, the flue gas generated by fuel combustion in the combustion chamber flows in a serpentine manner within the chamber. This increases the flow time of the flue gas within the chamber, thereby increasing the heating time and heating effect of the flue gas on the baffles and the movable baking pan. This is beneficial for improving the heat utilization rate of the flue gas, thereby improving fuel utilization and reducing energy waste. Attached Figure Description

Detailed Implementation

[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, an oven based on smoke baking is mainly used for baking traditional flavored foods. Specifically, it includes a box body 1, a combustion chamber 2 at the lower end of the box body 1, a chimney 3 connected to its inner cavity at the upper end of the box body 1, and multiple baffles 4 installed in the middle of the inner cavity of the box body 1. The multiple baffles 4 are staggered on the inner walls of both sides of the box body 1 to form a serpentine flue, and each baffle 4 is provided with a movable baking tray 5 that can be pulled out of the box body 1.

[0029] like Figure 2 As shown, there are three guide plates 4, which are respectively set as the first guide plate, the second guide plate and the third guide plate. The first guide plate and the second guide plate are both installed on the left inner wall of the box 1 and are distributed vertically at intervals. There is a gap between the first guide plate and the top wall of the inner cavity of the box 1. The second guide plate is set above the combustion chamber 2. The third guide plate is installed on the right inner wall of the box 1 and is located between the first guide plate and the second guide plate. This design can form a meandering serpentine flue in the inner cavity of the box 1. The flue inlet and outlet of the serpentine flue are connected to the combustion chamber 2 and the chimney 3, respectively, so that when the fuel is burning in the combustion chamber 2, the flue gas can flow meanderingly in the box 1, thereby prolonging the heating time and heating effect of the flue gas in the box 1, making full use of the heat of the flue gas, improving fuel utilization, and reducing energy waste.

[0030] It should be noted that the number of deflectors 4 can also be two, four, five, etc., depending on the actual needs.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the upper surface of the box 1 has a baking area, which is located on the side of the chimney 3. A baking tray cover is installed over the baking area. The baking tray cover includes a fixed cover 6 and a movable cover 7. The fixed cover 6 is fixed to the upper surface of the box 1. The movable cover 7 is hinged to the upper surface of the box 1 and is movably fitted outside the fixed cover 6. The movable cover 7 can rotate toward the opening of the fixed cover 6 and seal the opening.

[0032] The above design allows for full utilization of the blank area at the top of the oven 1, thereby increasing the actual baking area. The hinged rotating design of the movable cover 7 enables the opening and closing of the fixed cover 6, facilitating food handling, heat preservation, and baking.

[0033] Specifically, such as Figure 1 and Figure 2As shown, the interior of the baffle plate 4 has a slot that is compatible with the movable baking tray 5. The front of the slot is set as an opening and is connected to the outside of the box 1. The rear end of the movable baking tray 5 is inserted into the baffle plate 4 through the slot, and the front end of the movable baking tray 5 seals the opening of the slot.

[0034] Furthermore, the deflector plate 4 is a rectangular frame structure with a sealed rear end. The inner circle of the rectangular frame is a slot. The front end of the movable baking tray 5 has a handle, which can be inserted into the deflector plate 4, thus facilitating the baking and removal of food.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, a thermometer 8 is installed on the front of the deflector plate 4, located below the movable baking tray 5. The temperature reading area of ​​the thermometer 8 is located on the front of the cabinet 1. The thermometer 8 is a special thermometer for ovens or grills, which can monitor the temperature at the bottom of the deflector plate 4 in real time, thereby controlling the temperature at the bottom of the movable baking tray 5 so that users can carry out baking work.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, the side of the box 1 has a cleaning port 9. There are multiple cleaning ports 9, which are evenly distributed along the height of the box 1. Users can blow air into the cleaning ports 9 through an air pump to clean the inside of the box 1. In actual design, cleaning ports 9 can be set at each bend of the serpentine flue or at a position flush with the upper and lower end faces of the guide plate 4 to remove the soot attached to the upper and lower end faces of the guide plate 4 and the inner wall of the box 1.

[0037] It should be noted that the ash removal port 9 has an air inlet pipe connected to an external air pump on the side near the outside of the box 1, and a valve is installed on the air inlet pipe. When baking food and removing ash, the valve should be in the closed state.

[0038] Specifically, such as Figure 2 As shown, a guide block 10 is installed on one side of the inner wall of the bottom of the box 1. The guide block 10 is opposite to the other side of the inner wall of the bottom of the box 1 to form a combustion chamber 2. There is a gap between the upper end face of the guide block 10 and the lower end face of the adjacent guide plate 4 to form the inlet of the serpentine flue. The upper end of the guide block 10 near the combustion chamber 2 is inclined to guide the flue gas.

[0039] Specifically, such as Figure 1 As shown, the front of the combustion chamber 2 is set as an opening and is connected to the outside of the box 1. A grate 11 is installed in the combustion chamber 2, and an ash collection tray 12 that can be moved outward is set below the grate 11 to facilitate fuel combustion and ash collection.

[0040] Furthermore, the front of the housing 1 is equipped with slide rails located above and below the opening of the combustion chamber 2, and a baffle 13 for sealing the opening of the combustion chamber 2 is installed between the two slide rails. The opening size and opening / closing state of the combustion chamber 2 can be adjusted by moving the baffle 13 horizontally. By adjusting the opening size of the combustion chamber 2, the air intake can be adjusted, thereby adjusting the combustion rate and temperature.

[0041] It should be noted that the oven body 1 and the baffle plate 4 can be built by oneself using bricks and mud, which is simple, convenient and low-cost, fully demonstrating its accessibility and practicality; or they can be produced in a factory using modern technology, such as steel and insulation materials, which can ensure quality, reduce costs and facilitate wider promotion and application. The design concept of this oven fully considers different scenarios and needs, and can demonstrate its unique advantages in both rural self-built houses and large-scale production, with broad market prospects. More importantly, it makes food more flavorful and delicious.

[0042] Based on Example 1, Example 2 is provided.

[0043] like Figure 3 As shown, a heat conduction mechanism 14 is installed at the bottom of the baffle plate 4. The heat conduction mechanism 14 is set in the serpentine flue to absorb the heat of the flue gas in the flue and conduct heat to the bottom of the movable baking tray 5, thereby improving the actual heat conduction effect and the utilization rate of flue gas heat. Moreover, it can also play a certain heat preservation role after the fire is extinguished.

[0044] Furthermore, such as Figure 4 As shown, the heat conduction mechanism 14 includes a heat conduction plate 141 and heat conduction fins 142. The heat conduction plate 141 is embedded in the bottom of the guide plate 4, and the heat conduction fins 142 are installed at the bottom of the heat conduction plate 141 and extend into the serpentine flue. There are multiple heat conduction fins 142, which are evenly distributed along the width direction of the serpentine flue.

[0045] The lower surface of the slot of the guide plate 4 has a groove for installing the heat conduction plate 141. The upper end face of the heat conduction plate 141 is flush with the lower surface of the slot, so that the upper end face of the heat conduction plate 141 is in direct contact with the lower end face of the movable baking tray 5, thereby improving the actual heating effect.

[0046] Both the heat-conducting plate 141 and the heat-conducting fins 142 are made of aluminum alloy, which has excellent heat conduction performance and can absorb the heat of flue gas and conduct the heat to the guide plate 4, thereby improving the heat utilization rate.

[0047] It should be noted that a heat conduction mechanism 14 can also be installed on the top wall of the inner cavity of the box 1 to conduct heat to the baking area on the upper surface of the box 1.

[0048] like Figure 3As shown, the front of the box 1 is open and a door 15 is hinged to it. The gap between the door 15 and the opening of the box 1 is sealed by a high-temperature resistant sealant, which facilitates cleaning of the inside of the box 1 while ensuring the airtightness during high-temperature baking.

[0049] Furthermore, the bottom side of the box door 15 has a combustion chamber opening 16. When the box door 15 is closed, the combustion chamber opening 16 coincides with the opening of the combustion chamber 2, so that fuel can be added and burned in the combustion chamber 2. The slide rail and baffle 13 are installed on the bottom front of the box door 15 to facilitate the adjustment of the opening size of the combustion chamber 2.

[0050] Furthermore, the door 15 is also provided with a movable opening 17 that is compatible with and corresponds to the movable baking tray 5, so that the movable baking tray 5 can still be freely put in and taken out after the door 15 is closed, which is convenient for actual operation.

[0051] Furthermore, a viewing glass window is embedded in the door frame of the cabinet door 15. The viewing glass window is made of high-temperature resistant and explosion-proof glass, which facilitates the observation of the flue and soot accumulation inside the cabinet 1, thereby facilitating the user's actual operation and use.

[0052] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
