Description

Technical Field

[0001] The present invention relates to the field of ovens, and specifically, to an oven suitable for outdoor use. Background Art

[0002] The furnace body of a traditional kiln oven is built with stones, and an entrance and exit is reserved on the front side of the furnace body. The entrance and exit communicates with the inside of the furnace chamber. When in use, firewood is placed into the furnace chamber through the entrance and exit, and the firewood is ignited to heat the furnace chamber. When the temperature of the furnace chamber reaches the temperature for baking food ingredients, the food ingredients are then placed into the furnace chamber through the entrance and exit to cook the food ingredients. Since the furnace body of the traditional kiln oven is built with thick stones, in order to make the space of the furnace chamber large enough, the volume of the furnace body is generally relatively large, and most kiln ovens can only be set at a fixed point and cannot be moved.

[0003] Although there are also ovens that are convenient to move on the market, the opening degree of the chimneys of these ovens is fully open and cannot be adjusted in size. When baking, a large amount of heat follows the flue gas and is discharged outside the furnace chamber, resulting in poor heat preservation effect of the furnace chamber. Summary of the Invention

[0004] The purpose of the present invention is to provide an oven suitable for outdoor use and having a good heat preservation effect.

[0005] To achieve the above purpose, the present invention provides an oven, which includes a base and a furnace body. The furnace body is arranged on the base, and a furnace chamber is formed between the furnace body and the base. An entrance and exit is arranged at the front end of the furnace body, and the entrance and exit communicates with the furnace chamber. A chimney assembly is arranged at the upper part of the furnace body. The chimney assembly includes a sleeve and a damper. The sleeve communicates with the furnace chamber, and the damper is rotatably arranged in the sleeve. The damper can automatically adjust the smoke exhaust volume of the sleeve; the base is provided with a solid fuel combustion assembly and a gas fuel combustion assembly. The solid fuel combustion assembly and the gas fuel combustion assembly are respectively arranged on the left and right sides of the base, and both the solid fuel combustion assembly and the gas fuel combustion assembly can provide heat to the furnace chamber.

[0006] As can be seen from the above solution, by arranging a damper in the sleeve to automatically adjust the size of the smoke exhaust volume of the chimney. For example, when the heat in the furnace chamber is high and the air pressure is high, the damper automatically opens the smoke exhaust port to facilitate the rapid discharge of the flue gas; when the heat in the furnace chamber is low and the air pressure is low, the damper automatically closes the smoke exhaust port to reduce heat loss. The present invention uses the heat and air pressure generated during the baking process of the oven to automatically adjust the damper, so that the temperature in the furnace chamber remains in a relatively stable state, which is beneficial to improving its heat preservation effect and shortening the baking time of food. The present invention is also compatible with solid fuel and gas fuel at the same time. When one kind of fuel is suddenly consumed, another kind of fuel can be enabled, which is especially convenient for outdoor use. In addition, the two different fuels can also meet the different requirements of people for the fuel of food ingredient processing, and meet the requirements of customers for different tastes and flavors.

[0007] A further solution is that the damper is perpendicular to the axial direction of the sleeve, the damper can swing in the axial direction of the sleeve, the rotation axis of the damper is located in the middle of itself, and both sides of the damper rotate towards the upper and lower directions respectively.

[0008] As can be seen from the above solution, by setting a reasonable layout where both sides of the damper rotate towards the upper and lower directions respectively, it is beneficial to reduce the space required for the damper to rotate, ensure its smooth rotation, and when it is stationary, the damper is just perpendicular to the axial direction of the sleeve and the chimney is in a closed state.

[0009] A further solution is that the chimney assembly further includes a connecting pin and two elastic members. The connecting pin suspends the damper in the sleeve, and the damper rotates around the connecting pin. The two elastic members are respectively arranged on both sides of the damper, and the elastic members elastically abut between the damper and the inner peripheral wall of the sleeve.

[0010] As can be seen from the above solution, by setting the elastic members, the damper is located in the middle of the sleeve, avoiding the collision between the outer edge of the damper and the inner wall of the sleeve, which is beneficial to ensuring the smooth rotation of the damper.

[0011] A further solution is that the damper is perpendicular to the axial direction of the sleeve, the damper can swing in the axial direction of the sleeve, the rotation axis of the damper is located on its first side, and the second side of the damper rotates up and down around its first side.

[0012] A further solution is that an outer connecting seat is provided at the upper part of the furnace body. The outer connecting seat includes a cylindrical part, a first annular flange and a second annular flange. The first annular flange is arranged inside the first end of the cylindrical part, and a first through hole is provided in the middle of the first annular flange part. The second annular flange is arranged outside the second end of the cylindrical part. The sleeve is arranged inside the cylindrical part and supported on the first annular flange, and the inside of the sleeve is communicated with the first through hole; in the radial projection plane, the projection of the outer peripheral edge of the damper falls on the first annular flange.

[0013] As can be seen from the above solution, by setting the projection of the outer peripheral edge of the damper to fall on the first annular flange, sundries cannot directly fall into the furnace from the chimney.

[0014] A further solution is that a first cavity and a first installation groove are provided on the first side of the base. The first installation groove is arranged inside the first cavity, the first installation groove is communicated with the furnace cavity, the solid combustion assembly is detachably arranged inside the first installation groove, and the solid combustion assembly is provided with a ventilation hole whose opening size can be adjusted, and the ventilation hole is communicated with the first cavity.

[0015] As can be seen from the above solution, by setting the ventilation hole whose opening size can be adjusted, it is beneficial to adjust the amount of air entering the first cavity from the ventilation hole, and further adjust the intensity of the solid fuel during combustion, so as to realize the adjustment of the cooking heat.

[0016] A further solution is that the solid combustion component includes a containing frame, an inner plate, an outer plate and a handle. The outer plate is arranged on one side of the containing frame, the inner plate is arranged between the containing frame and the outer plate, and the handle sequentially passes through the outer plate and the inner plate and is connected to the containing frame; the outer plate is provided with first ventilation holes, the inner plate is provided with second ventilation holes, the first ventilation holes are communicated with the second ventilation holes, and the handle can drive the inner plate to move along the width direction of the second ventilation holes so as to adjust the communication amount between the first ventilation holes and the second ventilation holes.

[0017] As can be seen from the above solution, by arranging the inner plate that can move relative to the outer plate, it is convenient to adjust the communication amount between the first ventilation holes and the second ventilation holes according to the needs of the cooking heat, that is, to adjust the air intake amount, and further adjust the combustion degree of the solid fuel or the heat in the furnace.

[0018] A further solution is that a second cavity and a surrounding plate are arranged on the second side of the base. The second cavity is communicated with the furnace chamber, the surrounding plate surrounds the outside of the second cavity, and the surrounding plate is provided with a plurality of third ventilation holes penetrating therethrough. The third ventilation holes are communicated with the second cavity; the gas combustion component includes a gas storage device and a burner head. The gas storage device is arranged in the middle of the base, the burner head is arranged in the second cavity and faces the furnace chamber, and the gas storage device is communicated with the burner head.

[0019] As can be seen from the above solution, by arranging the second cavity and the third ventilation holes, on the one hand, it is convenient for air to enter from the third ventilation holes, so that the gas fuel can be fully burned, and on the other hand, it is also beneficial to heat dissipation.

[0020] A further solution is that a first heat conducting plate and a heat insulating plate are arranged in the middle of the base. The heat insulating plate is arranged below the first heat conducting plate, and a receiving cavity is further arranged below the heat insulating plate of the base. The gas storage device is arranged in the receiving cavity.

[0021] A further solution is that heat insulating and heat preserving layers are arranged at the front and rear ends of the base, the front and rear ends of the furnace body, and the left and right sides of the furnace body. Description of the Drawings

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Specific embodiments

[0033] Refer to Figure 1 and Figure 2 , a kind of oven provided in this embodiment includes a base 1 and an oven body 2. The oven body 2 is arranged on the base 1. A furnace chamber is formed between the oven body 2 and the base 1. An entrance and exit is arranged at the front end of the oven body 2, and the entrance and exit communicates with the furnace chamber.

[0034] The oven body 2 in this embodiment is set as a trapezoid. A chimney assembly 3 is arranged on the upper part of the oven body 2. The chimney assembly 3 communicates with the furnace chamber and is used for discharging smoke. The base 1 is set as a rectangle matching the oven body 2. A solid combustion assembly 4 and a gas combustion assembly 5 are arranged in the base 1. The solid combustion assembly 4 and the gas combustion assembly 5 are respectively arranged on the left and right sides of the base 1. Both the solid combustion assembly 4 and the gas combustion assembly 5 can provide heat to the furnace chamber.

[0035] A gas switch 11 and a display screen 12 are arranged at the front end of the base 1. The gas switch 11 is used to control the ignition and extinguishing of the gas combustion assembly 5. A temperature sensor 6 is arranged on the inner side of the rear end of the oven body 2 and is used to detect the temperature in the furnace chamber. The display screen 12 is connected to the temperature sensor 6 and is used to display the current temperature value of the furnace chamber.

[0036] Refer to Figures 2 to 7 , the chimney assembly 3 includes a sleeve 31 and a damper 32. The first end of the sleeve 31 communicates with the furnace chamber, and the second end of the sleeve 31 communicates with the outside. The damper 32 is rotatably arranged in the sleeve 31, and the damper 32 can automatically adjust the smoke discharge amount of the sleeve 31.

[0037] The air damper 32 is perpendicular to the axial direction of the sleeve 31, and the air damper 32 can swing up and down in the axial direction of the sleeve 31. In this embodiment, the sleeve 31 is arranged in the vertical direction. In the normal state, the air damper 32 is in the horizontal state, and the liquid drainage channel inside the sleeve 31 is in the closed state. After the air damper 32 rotates, the sleeve 31 is in the open state, and its opening degree depends on the rotation degree of the air damper 32.

[0038] In one embodiment, the rotation axis of the air damper 32 is located in the middle of itself, and the air damper 32 rotates around its own middle, that is, both sides of the air damper 32 rotate towards the upper and lower directions respectively. When the air damper 32 rotates 90°, it is in the vertical state, and at this time, the inside of the sleeve 31 is in the maximum open state.

[0039] Specifically, the chimney assembly 3 further includes a connecting pin 33 and two elastic members 34. The connecting pin 33 passes through the middle of the air damper 32 to suspend the air damper 32 in the sleeve 31. The air damper 32 rotates around the connecting pin 33. The two elastic members 34 are respectively arranged on both sides of the air damper 32 and sleeved on the connecting pin 33, and the elastic members 34 are elastically abutted between the air damper 32 and the inner peripheral wall of the sleeve 31. The elastic member 34 is preferably a spring. The setting of the elastic member 34 makes the air damper 32 always in the middle of the sleeve 31, and there is a safety distance between its outer peripheral edge and the inner wall of the sleeve 31 to prevent the air damper 32 from colliding with the inner wall of the sleeve 31 when rotating.

[0040] The shape of the air damper 32 is set to be circular. A strip-shaped groove 321 and two connecting parts 322 are arranged in the middle of the air damper 32. The setting of the strip-shaped groove 321 is beneficial to improving the structural strength of the air damper 32. The two connecting parts 322 are respectively arranged at both ends of the strip-shaped groove 321, and the connecting parts 322 vertically protrude upward from the notch of the strip-shaped groove 321. A first mounting hole 3221 is penetrated through the connecting part 322. The two first mounting holes 3221 are coaxially arranged for connecting with the connecting pin 33. In this embodiment, one of the first mounting holes 3221 is set to be circular, and the other first mounting hole 3221 is set to be oval, which is convenient for processing and installation.

[0041] The sleeve 31 is provided with two second mounting holes 311, and the two second mounting holes 311 are coaxially arranged.

[0042] The connecting pin 33 is set to be "L"-shaped. The connecting pin 33 sequentially passes through one of the second mounting holes 311, one of the elastic members 34, the two first mounting holes 3221, and the other elastic member 34 and then passes out of the other second mounting hole 311. In order to prevent the connecting pin 33 from separating from the sleeve 31, a nut 35 is preferably arranged at the end of the connecting pin 33 passing through the sleeve 31.

[0043] In order to better fix the sleeve 31, the furnace body 2 is provided with an outer connecting seat 21 and an inner connecting seat 22 at its upper part, and both the outer connecting seat 21 and the inner connecting seat 22 are set to be annular structures.

[0044] The outer connecting seat 21 includes a cylindrical portion 211, a first annular flange 212, and a second annular flange 213. The first annular flange 212 is disposed inside the first end of the cylindrical portion 211, and a first through hole 2121 is provided in the middle of the first annular flange 212; the second annular flange 213 is disposed outside the second end of the cylindrical portion 211 for abutting against the outer wall of the furnace body 2.

[0045] The inner connecting seat 22 is provided with a second through hole 221 and a third annular flange 222, and the second through hole 221 is disposed inside the third annular flange 222. The inner connecting seat 22 is disposed on the inner wall of the furnace body 2, and the outer connecting seat 21 is disposed on the inner connecting seat 22. At this time, the first annular flange 212 is supported on the third annular flange 222, and the first through hole 2121 communicates with the second through hole 221.

[0046] The sleeve 31 is disposed inside the cylindrical portion 211 and is supported on the first annular flange 212, and the inside of the sleeve 31 communicates with the first through hole 2121.

[0047] In the radial projection plane, the projection of the outer peripheral edge of the air damper 32 falls on the first annular flange 212, that is, the gap 36 between the outer peripheral edge of the air damper 32 and the inner wall of the sleeve 31 is blocked by the first annular flange 212 to prevent foreign matters from directly entering the furnace.

[0048] In other embodiments, the air damper is perpendicular to the axial direction of the sleeve, the air damper can swing up and down in the axial direction of the sleeve, the rotation axis of the air damper can be located on its own first side, and the second side of the air damper rotates up and down around its first side, that is, the connecting pin passes through the first side of the air damper, and the second side of the air damper rotates up and down around the connecting pin.

[0049] See Figure 9 and Figure 10 and in combination with Figure 1 、 Figure 2 and Figure 4, a first cavity 13 and a first mounting groove 14 are provided on the first side of the base 1, and the first mounting groove 14 is arranged within the first cavity 13. The first cavity 13 is provided with a fourth mounting hole 131 on the side away from the base 1. The solid combustion component 4 enters the first cavity 13 from the fourth mounting hole 131 and is arranged within the first mounting groove 14. The first cavity 13 is provided with a cover plate 15 above the first mounting groove 14, and a plurality of first through holes 151 are formed in the cover plate 15. The first cavity 13 communicates with the furnace chamber through the first through holes 151. More and denser first through holes 151 should be provided directly above the solid combustion component 4 on the cover plate 15. Preferably, a second through hole 152 with a larger diameter is additionally provided between the plurality of first through holes 151 to facilitate the passage of flames. Fewer and sparser first through holes 151 can be provided above the two sides of the solid combustion component 4 on the cover plate 15. The setting of the cover plate 15, on the one hand, is beneficial to preventing the soot generated during the combustion of solid fuel from entering the furnace chamber to contaminate food, and on the other hand, it can also prevent food from falling into the solid combustion component 4.

[0050] The solid combustion component 4 is detachably arranged within the first mounting groove 14, and the solid combustion component 4 enters the first mounting groove 14 from the fourth mounting hole 131. Elastic clamping components 16 are respectively arranged on both sides of the first mounting groove 14. The elastic clamping component 16 includes a V-shaped elastic piece 161 and a clamping post 162. The clamping post 162 is arranged on one free end of the V-shaped elastic piece 161. The V-shaped elastic piece 161 is arranged on the outside of the first mounting groove 14, and the clamping post 162 passes through the groove wall of the first mounting groove 14 and extends into the first mounting groove 14.

[0051] The solid combustion component 4 includes a containing frame 41, an inner plate 42, an outer plate 43, and a handle 44. The containing frame 41 is used for containing solid fuel. Card slots 413 are arranged on the outer walls of both sides of the containing frame 41, and the card slots 413 are cooperatively connected with the clamping posts 162 to achieve their detachable connection. The outer plate 43 is arranged on one side of the containing frame 41, and the outer plate 43 just blocks the fourth mounting hole 131. The outer plate 43 and the containing frame 41 are fixedly connected through two connecting columns 45. The inner plate 42 is arranged between the containing frame 41 and the outer plate 43. The inner plate 42 is arranged between the two connecting columns 45, and there is a preset distance between the end of the inner plate 42 and the connecting columns 45. One end of the handle 44 protrudes from the outer plate 43 to facilitate the operation of the user, and the other end of the handle 44 sequentially passes through the outer plate 43 and the inner plate 42 and is connected to the containing frame 41.

[0052] The outer plate 43 is provided with a first sliding groove 431 and four first ventilation holes 432. The first sliding groove 431 is arranged in the middle of the outer plate 43. The first sliding groove 431 extends in the horizontal direction, and the extension length of the first sliding groove 431 is greater than the diameter of the middle part of the handle 44. The four first ventilation holes 432 are arranged in a horizontal row, and the first ventilation holes 432 extend in the up and down direction.

[0053] The inner plate 42 is provided with a third mounting hole 421 and four second ventilation holes 422. The third mounting hole 421 is arranged in the middle of the inner plate 42. The third mounting hole 421 is in clearance fit with the middle part of the handle 44. The first ventilation holes 432 and the second ventilation holes 422 are arranged in one-to-one correspondence and communicated with each other, facilitating the entry of external air into the first cavity 13. The first ventilation holes 432 and the second ventilation holes 422 both extend in the up-and-down direction.

[0054] Inside the storage frame 41, a storage groove 411 for storing solid fuel is provided. On one side of the storage frame 41, a second sliding groove 412 is provided. The second sliding groove 412 corresponds to the first sliding groove 431. The handle 44 sequentially passes through the first sliding groove 431 and the third mounting hole 421 and is inserted into the second sliding groove 412. The handle 44 can drive the inner plate 42 to move relative to the outer plate 43 along the extending direction of the first sliding groove 431, that is, along the width direction of the second ventilation hole 422, so that the first ventilation hole 432 can be misaligned with the second ventilation hole 422 to adjust the size of the communication amount between the first ventilation hole 432 and the second ventilation hole 422. The maximum value of this communication amount is the width size of the first ventilation hole 432 or the second ventilation hole 422; the minimum value of this communication amount is 0. At this time, the first ventilation hole 432 and the second ventilation hole 422 are completely misaligned and not communicated. In this embodiment, by moving the horizontal position of the inner plate 42, the size of the communication amount of the ventilation holes is adjusted, and then the amount of air entering the first cavity 13 is adjusted.

[0055] When the solid combustion component 4 burns, the flame and heat pass through the first through hole 151 and enter the furnace chamber. Although the inlet and outlet of the furnace chamber can also provide the necessary air for combustion, during the combustion process, the air flow in the furnace chamber goes from bottom to top, and it is difficult for the air entering from the inlet and outlet to pass through the first through hole 151 of the cover plate 15 in the reverse direction and make full contact with the solid fuel, resulting in incomplete combustion of the solid fuel in the base 1 or insufficient fire, unable to meet the user's fire use requirements. To solve this problem, the solid combustion component 4 is provided with a plurality of ventilation holes with adjustable opening sizes. The ventilation holes are communicated with the first cavity 13 to facilitate the entry of air and provide sufficient oxygen for the full combustion of the solid fuel. When the solid combustion component 4 is not in use, the ventilation holes can be completely closed to prevent sundries or bugs from entering.

[0056] On the second side of the base 1, a second cavity 17 and a surrounding plate 18 are provided. The upper part of the second cavity 17 is communicated with the furnace chamber. The surrounding plate 18 surrounds the outside of the second cavity 17. The surrounding plate 18 is provided with a plurality of third ventilation holes 181 penetratingly, and the third ventilation holes 181 are communicated with the second cavity 17.

The burner head 51 is arranged in the second cavity 17 and is arranged towards the furnace chamber. The gas storage device is communicated with the burner head 51.

[0058] In the middle of the base 1, a first heat conducting plate 19 and a heat insulating plate 10 are provided. The heat insulating plate 10 is arranged below the first heat conducting plate 19. The base 1 is further provided with a receiving cavity below the heat insulating plate 10, and the gas storage device is arranged in the receiving cavity. The base 1 is provided with a second heat conducting plate 20 around the burner 51, and the second heat conducting plate 20, the first heat conducting plate 19 and the cover plate 15 are all at the same height.

[0060] In summary, in the present invention, a damper is arranged in the sleeve to automatically adjust the smoke exhaust volume of the chimney. For example, when the heat in the furnace chamber is high and the air pressure is large, the damper automatically opens the smoke exhaust port to facilitate the rapid discharge of flue gas; when the heat in the furnace chamber is low and the air pressure is small, the damper automatically closes the smoke exhaust port to reduce heat loss. The present invention utilizes the heat and air pressure generated during the baking process of the oven to automatically adjust the damper, so that the temperature in the furnace chamber remains in a relatively stable state, which is beneficial to improving its heat preservation effect and shortening the baking time of food. The present invention is compatible with both solid fuel and gas fuel at the same time. When one kind of fuel is suddenly consumed, another kind of fuel can be enabled, which is especially convenient for outdoor use. In addition, the two different fuels can also meet the different requirements of people for the fuel of food processing and satisfy the different taste and flavor requirements of customers.
