Description

Technical Field

[0002] In an open-type baking machine, it includes a housing and a cavity arranged inside the housing. The baking temperature in the cavity can reach a high temperature above 800 °C, enabling food to be quickly roasted. Due to the high temperature in the cavity, openings need to be provided on the front side of the housing and the cavity. And the high temperature in the cavity will also be transmitted to the surface of the housing, increasing the surface temperature of the housing. During actual use, the housing is often touched, and the excessively high surface temperature of the housing may cause safety accidents such as burns, presenting relatively large potential safety hazards.

In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0035] Such as Figures 1 to 8As shown in the figure, a baking machine includes a baking machine housing, a baking cavity provided inside the baking machine housing, and a baking inner container provided inside the baking cavity for supporting food. The air flow between the inside of the baking machine housing and the inside of the baking cavity is not connected. The baking cavity is arranged with an open front side. An opening 161 is provided on the front side of the baking machine housing. The external air and the air flow inside the baking cavity are connected through the opening 161 on the front side of the baking machine housing and the open front side of the baking cavity. A heating device 41 is provided inside the baking cavity; a heat insulation gap is formed between the baking machine housing and the baking cavity. A blowing mechanism 4 is provided inside the heat insulation gap. An air inlet 121 and an air outlet 151 are provided on the baking machine housing. The air inside the baking cavity is heated by the heating device 41 to perform high-temperature baking on the food on the baking inner container. By forming a heat insulation gap between the baking machine housing and the baking cavity, the high temperature inside the baking cavity can be effectively reduced from being transferred to the surface of the baking machine housing. Moreover, a blowing mechanism 4 is also provided inside the heat insulation gap. The blowing mechanism 4 blows external cold air into the heat insulation gap between the baking machine housing and the baking cavity through the air inlet 121, further blocking the transfer of the high temperature inside the baking cavity to the surface of the baking machine housing. The air flow inside the heat insulation gap after heat transfer is discharged through the air outlet 151, effectively reducing the temperature of the surface of the baking machine housing. When a person touches it, only a slight heat is felt and there will be no scalding, solving the problem of the safety hazard of scalding caused by the too high temperature on the surface of the baking machine housing.

[0036] Specifically, generally the heating device 41 is arranged at the top of the baking cavity and is relatively close to the front side of the baking machine housing, resulting in a relatively higher temperature at the top of the front side of the baking machine housing compared to the temperatures of other surfaces of the baking machine housing. Even after the blowing mechanism 4 and the heat insulation gap are provided, the temperature at the top of the front side of the baking machine housing is still relatively high. To solve this problem, a heating box fixing plate is provided at the top of the baking cavity. The heating box fixing plate includes a mounting plate 261, a first vertical plate 262, a horizontal connecting plate 263, and a second vertical plate 264. One end of the mounting plate 261 is connected to the top end of the first vertical plate 262. The bottom end of the first vertical plate 262 is connected to one end of the horizontal connecting plate 263. The other end of the horizontal connecting plate 263 is connected to the bottom end of the second vertical plate 264. The top end of the second vertical plate 264 extends upward. The first vertical plate 262, the horizontal connecting plate 263, and the second vertical plate 264 form a U-shaped partition groove. The second vertical plate 264 is located on the front side of the baking cavity. The heating device 41 is installed on the side of the mounting plate 261 facing the baking inner container; in this way, by providing a U-shaped partition groove at the front side end of the heating box fixing plate close to the baking machine housing body, the heat insulation distance between the heating device 41 and the front side of the baking machine housing is increased, effectively reducing the temperature of the front side of the baking machine housing and solving the problem of the too high temperature of the front side of the baking machine housing caused by the too close distance between the front side of the baking machine housing and the heating device 41.

[0037] Specifically, the baking machine housing includes a housing top plate 11, a housing bottom plate 12, a housing left side plate 13, a housing right side plate 14, a housing rear side plate 15, and a housing front side plate 16. The housing top plate 11, the housing bottom plate 12, the housing left side plate 13, the housing right side plate 14, the housing rear side plate 15, and the housing front side plate 16 together form a cuboid housing structure, and an opening 161 is provided on the housing front side plate 16.

[0038] Specifically, the baking cavity includes a cavity top plate 21, a cavity bottom plate 22, a cavity left side plate 23, a cavity right side plate 24, and a cavity rear side plate 25. The cavity top plate 21, the cavity bottom plate 22, the cavity left side plate 23, the cavity right side plate 24, and the cavity rear side plate 25 together form a rectangular cavity structure with an open front side; there is a certain heat insulation gap between the housing top plate 11 and the cavity top plate 21, a certain heat insulation gap between the housing bottom plate 12 and the cavity bottom plate 22, a certain heat insulation gap between the housing left side plate 13 and the cavity left side plate 23, a certain heat insulation gap between the housing right side plate 14 and the cavity right side plate 24, a certain heat insulation gap between the housing rear side plate 15 and the cavity rear side plate 25, and a certain heat insulation gap between the housing front side plate 16 and the second vertical plate 264.

[0039] Further, the heat insulation gap between the housing top plate 11 and the cavity top plate 21 is 75 - 95 mm, the heat insulation gap between the housing bottom plate 12 and the cavity bottom plate 22 is 75 - 95 mm, the heat insulation gap between the housing left side plate 13 and the cavity left side plate 23 is 15 - 35 mm, the heat insulation gap between the housing right side plate 14 and the cavity right side plate 24 is 15 - 35 mm, the heat insulation gap between the housing rear side plate 15 and the cavity rear side plate 25 is 35 - 55 mm, and the heat insulation gap between the housing front side plate 16 and the second vertical plate 264 is 5 - 20 mm.

[0040] As a preferred embodiment, the heat insulation gap between the housing top plate 11 and the cavity top plate 21 is 85 mm, the heat insulation gap between the housing bottom plate 12 and the cavity bottom plate 22 is 85 mm, the heat insulation gap between the housing left side plate 13 and the cavity left side plate 23 is 25 mm, the heat insulation gap between the housing right side plate 14 and the cavity right side plate 24 is 25 mm, the heat insulation gap between the housing rear side plate 15 and the cavity rear side plate 25 is 45 mm, and the heat insulation gap between the housing front side plate 16 and the second vertical plate 264 is 10 mm.

[0041] Further, in order to support and fix the entire structure, the housing top plate 11 and the cavity top plate 21 are fixedly connected through a connecting member, and the housing rear side plate 15 and the cavity rear side plate 25 are fixedly connected through a connecting member.

[0042] Specifically, the blowing mechanism 4 can be arranged at a required position in the heat insulation gap between the baking machine housing and the baking cavity according to actual needs, such as being arranged at the bottom of the baking machine housing, at the top of the baking machine housing, at the rear side of the baking machine housing, at the left side of the baking machine housing, at the right side of the baking machine housing, etc.

[0043] In this embodiment, the blowing mechanism 4 is arranged on the housing bottom plate 12, the air inlet 121 is arranged on the housing bottom plate 12, the air outlet 151 is arranged on the housing rear side plate 15. The position where the blowing mechanism 4 is arranged corresponds to the position of the air inlet 121. External cold air acts through the blowing mechanism 4 and is blown into the heat insulation gap between the baking machine housing and the baking cavity from the air inlet 121 from bottom to top, and then discharged through the air outlet 151.

[0044] As a preferred embodiment, the blowing mechanism 4 adopts a hair dryer.

[0045] As a preferred embodiment, two hair dryers are arranged, and two air inlets 121 are arranged. The hair dryers and the air inlets 121 are in one-to-one correspondence. Arranging two hair dryers and air inlets 121 can ensure that sufficient external cold air can be blown into the gap between the baking machine housing and the baking cavity to meet the cooling requirements of the baking machine.

[0046] Because the baking machine is generally placed on a table for work, during the baking process of the baking machine, the high-temperature air inside will escape from the opening 161, and part of it will directly act on the table on which the baking machine is placed. After a long time, it will damage the table. To solve this problem, an air outlet slot 162 is also arranged on the housing front side plate 16. The blowing mechanism 4 blows external cold air into the heat insulation gap between the baking machine housing and the baking cavity, and then blows it out through the air outlet slot 162 to act on the table on which the baking machine is placed.

[0047] Furthermore, the specific setting position of the air outlet slot 162 on the housing front side plate 16 can be set according to actual needs. For example, the air outlet slot 162 is located above the opening 161, below the opening 161, to the left of the opening 161, to the right of the opening 161, etc.

[0048] In this embodiment, the air outlet slot 162 is arranged at the lower part of the front side plate 16 of the housing, and the air outlet slot 162 is located below the opening 161. Since the blowing mechanism 4 is arranged on the bottom plate 12 of the housing, the air temperature at the bottom of the baking machine housing is the lowest. In the gap between the baking machine housing and the baking cavity, the temperature of the external cold air will continuously increase from bottom to top. Therefore, the air outlet slot 162 is arranged at the lower part of the front side plate 16 of the housing, and the air at the bottom of the baking machine housing directly blows out through the air outlet slot 162 and acts on the tabletop where the baking machine is placed to increase the cooling effect on the tabletop.

[0049] Furthermore, a wind guide plate 1621 is arranged at the air outlet slot 162. One end of the wind guide plate 1621 is connected to the air outlet slot 162, and the other end of the wind guide plate 1621 inclines downward. In this way, the air at the bottom of the baking machine housing directly blows towards the tabletop where the baking machine is placed in a concentrated manner through the wind guide plate 1621 at the air outlet slot 162, further increasing the cooling effect on the tabletop.

[0050] Specifically, the baking inner container includes a left inner container side plate 31, a right inner container side plate 32, a rear inner container side plate, and a support bottom plate 34. The left inner container side plate 31, the right inner container side plate 32, the rear inner container side plate, and the support bottom plate 34 are cooperatively installed to form an inner container structure with an open upper side and an open front side, and the support bottom plate 34 is placed on the inner cavity bottom plate 22.

[0051] Furthermore, clamping grooves 35 horizontally arranged in the front-rear direction are arranged on both the left inner container side plate 31 and the right inner container side plate 32. A plurality of clamping grooves 35 are arranged on both the left side and the right side of the baking inner container. The positions and numbers of the clamping grooves 35 on the left side of the baking inner container correspond to those of the clamping grooves 35 on the right side of the baking inner container one by one. The left end and the right end of the tray 36 for carrying food are respectively clamped in the clamping grooves 35 on the left side of the baking inner container and the clamping grooves 35 on the right side of the baking inner container. The tray 36 can be clamped in the clamping grooves 35 on the left side of the baking inner container and the clamping grooves 35 on the right side of the baking inner container at different heights according to actual needs to adjust the baking height of the tray 36, or a tray 36 can be clamped in the clamping grooves 35 on the left side of the baking inner container and the clamping grooves 35 on the right side of the baking inner container at multiple different heights simultaneously, and objects are respectively placed in each tray 36 to realize simultaneous baking of multiple objects.

[0052] Since oil juice will be discharged from the food during the baking process, in order to drain the discharged oil juice in time and avoid the oil juice flowing in the baking machine and being difficult to clean, a plurality of mesh holes 361 for draining the oil juice are arranged on the tray 36, and an oil collecting tray 37 is arranged on the support bottom plate 34. The oil collecting tray 37 is located below the tray 36. During the baking process, the oil juice flowing out of the food is drained through the mesh holes 361 and collected in the oil collecting tray 37. After the oil juice in the oil collecting tray 37 is full, the oil collecting tray 37 is pulled out to pour out the oil juice, and then the oil collecting tray 37 is pushed into the baking inner container for use.

[0053] Further, the oil collecting tray 37 includes an oil collecting groove and a clamping surface disposed around the edge of the oil collecting groove. During the baking process, the oil juice flowing out of the food is drained through the mesh holes 361 and collected in the oil collecting groove of the oil collecting tray 37.

[0054] Further, when the oil juice in the oil collecting tray 37 is full, the oil collecting tray 37 needs to be pulled out to drain the oil juice. To facilitate pulling out the oil collecting tray 37, clamping holes are provided on the clamping surface. By clamping the clamping holes with a clip, the oil collecting tray 37 is pulled out from the baking inner cavity, which is convenient to operate.

[0055] Further, to prevent the oil juice from not being concentrated and collected in the oil collecting tray 37, an oil guiding tray 38 is provided in the baking inner cavity. The oil guiding tray 38 is located between the supporting plate 36 and the oil collecting tray 37. A plurality of oil guiding holes are provided on the oil guiding tray 38. The oil guiding tray 38 is arranged in a concave shape with a high perimeter and a low middle. During the baking process, the oil juice flowing out of the food is drained through the mesh holes 361, falls onto the oil guiding tray 38, is concentrated in the middle of the oil guiding tray 38, and then falls into the oil collecting tray 37 through the oil guiding holes on the oil guiding tray 38, preventing the oil juice from flowing everywhere.

[0056] When the juice in the oil collecting tray is full, the oil collecting tray 37 needs to be clamped out by a clip to drain the juice and then put back into the baking machine for use. However, each time the oil collecting tray 37 is clamped out, the supporting bottom plate 34 and the entire baking inner cavity may be pulled out together with the oil collecting tray 37, resulting in dislocation, and manual pushing back to the original position is required, which is cumbersome to operate. To solve this problem, a limiting groove is provided on the inner cavity bottom plate 22, and a protruding limiting block 221 is provided on one side of the limiting groove close to the front side of the baking inner cavity. A downwardly protruding clamping plate 341 is provided on the surface of the supporting bottom plate 34 facing the inner cavity bottom plate 22. The clamping plate 341 is stuck in the limiting groove, and the limiting block 221 restricts the supporting bottom plate 34 from moving together with the oil collecting tray 37 when the oil collecting tray 37 is clamped out of the baking inner cavity. The number of the limiting grooves and the clamping plates 341 can be set according to actual needs. The more the number of the limiting grooves and the clamping plates 341 is set, the better the limiting effect is, but the entire structure will be more complex.

[0057] In this embodiment, two limiting grooves are provided, and both of the two limiting grooves are located on the front side of the inner cavity bottom plate 22. One of the limiting grooves is close to the inner cavity left side plate 23, and the other limiting groove is close to the inner cavity right side plate 24. A protruding limiting block 221 is provided on one side of each limiting groove close to the front side opening of the baking inner cavity; two clamping plates 341 are provided, and the positions of the two clamping plates 341 on the supporting bottom plate 34 correspond to the positions of the two limiting grooves one by one. One of the clamping plates 341 is stuck in one of the limiting grooves, and the other clamping plate 341 is stuck in the other limiting groove.

[0058] Further, a partition net 39 is arranged in the baking cavity. The partition net 39 is located above the baking inner container, between the heating device 41 and the tray 36. A plurality of mesh holes are arranged on the partition net 39. The arrangement of the partition net 39 prevents the food placed on the tray 36 from accidentally touching the heating device 41, and at the same time is conducive to uniform hot air, making the temperature in the baking cavity uniform.

[0059] During the installation of the baking machine, the baking inner container needs to be pushed into the baking cavity, and then other accessories are installed. However, during the subsequent installation process, it is often found that the baking inner container is installed in the wrong direction due to the worker's incorrect installation, resulting in the need to disassemble the installed accessories and reinstall them, which is time-consuming and laborious. Moreover, there is also a possibility of damaging the accessories during the disassembly process, increasing the installation cost of the entire baking machine. To solve this problem, a limit screw 2631 is arranged on the side of the horizontal connecting plate 263 facing the baking inner container; since the upper side of the baking inner container is in an open form, when the baking inner container is correctly installed, the downward protruding limit screw 2631 can be smoothly installed in cooperation with the baking inner container. When the baking inner container is installed in the wrong direction, because a support bottom plate 34 is arranged at the bottom of the baking inner container, the limit screw 2631 will interfere with the installation of the support bottom plate 34, resulting in the baking inner container not being smoothly installed.

[0060] Specifically, a PCB board for controlling the operation of the entire baking machine is installed on the rear side plate 15 of the housing. The PCB board is connected to the power supply through a power cord, and both the blowing mechanism 4 and the heating device 41 are connected to the PCB board.

[0061] Further, to facilitate the control of the baking machine, a control panel 42 is arranged on the front side plate 16 of the housing. Control buttons are arranged on the control panel 42, and the control panel 42 is connected to the PCB board.

[0062] Further, to facilitate the movement of the baking machine, a carrying handle 111 is arranged on the top plate 11 of the housing.

[0063] A baking method for the baking machine as described above specifically includes the following steps:

[0064] Step S1: Start the baking machine;

[0065] Step S2: Set the baking temperature;

[0066] Step S3: Set the baking time;

[0067] Step S4: The heating device 41 preheats and rises to the preheating temperature within the set time (such as 90 seconds);

[0068] Step S5: The heating device 41 rises from the preheating temperature to the set baking temperature within the set time;

[0069] Step S6: Keep the baking machine at the set baking temperature for baking the food within the set baking time;

[0070] Step S7: When the countdown of the set baking time is completed, turn off other components of the baking machine except the blowing mechanism 4;

[0071] Step S8: When the heat dissipation time of the blowing mechanism 4 is reached, turn off the blowing mechanism 4.

[0072] Specifically, according to the baking temperature of different foods, different baking temperatures can be adjusted. In this technical solution, the set baking temperature is 550°C to 850°C, and any temperature within this range can be set according to actual needs.

[0073] Further, the number of the heating devices 41 can be set according to actual needs. In this embodiment, two groups of heating devices 41 are provided.

[0074] Since the heating device 41 needs to maintain the set baking time after heating up to the set baking temperature, but the heating device 41 cannot always maintain the heating state during the set baking time. Keeping the heating state all the time will cause the baking temperature to be too high. Therefore, this technical solution divides the baking temperature of 550°C to 850°C into three different baking temperature ranges, and controls the working state of the heating device 41 within the set baking time according to different baking temperature ranges:

[0075] (1) The first range: The set baking temperature is between 400°C and 550°C. The two groups of heating devices 41 are respectively controlled as follows: The heating device 41 is turned on and works at 50% power, and the two groups of heating devices 41 work alternately in a cycle of 10 seconds. That is, in the first 10 seconds, the first group of heating devices 41 is turned on and works at 50% power and the second group of heating devices 41 is turned off; in the second 10 seconds, the second group of heating devices 41 is turned on and works at 50% power and the first group of heating devices 41 is turned off; in the third 10 seconds, the first group of heating devices 41 is turned on and works at 50% power and the second group of heating devices 41 is turned off...

[0076] (2) The second range: The set baking temperature is between 550°C and 700°C. The two groups of heating devices 41 are respectively controlled as follows: The heating device 41 is turned on and works at 87.5% power. The first group of heating devices 41 works for 10 seconds and stops for 2.5 seconds, and the second group of heating devices 41 works for 2.5 seconds and stops for 2.5 seconds. That is, the first group of heating devices 41 is turned on and works at 87.5% power for 10 seconds, then stops for 2.5 seconds, then works for 10 seconds, and then stops for 2.5 seconds...; while at the same time, the second group of heating devices 41 is turned on and works at 87.5% power for 2.5 seconds, then stops for 2.5 seconds, then works for 2.5 seconds, and then stops for 2.5 seconds...

[0077] (3) Third gear: Baking temperature is set between 700 °C and 850 °C, and the two heating devices 41 are respectively controlled as follows: The two heating devices 41 are turned on simultaneously and operate continuously at 100% power throughout the set baking time.
