[0002] Baked naan is the most important and indispensable food in the daily life of the Uygur people, and is also a unique food in the Uygur food culture. Authentic baked naan is mainly made by baking in a naan pit. The rolled baked naan dough is attached to the pre-heated naan pit wall, and the baked naan dough is baked by the heated naan pit wall to form baked naan. The naan pit is a special stove for the Uygur people in Xinjiang, which is very rare in other regions. Therefore, many baked naan products (baked naan boxes, baked naan ovens or baked naan machines, etc.) have appeared on the market to replace the naan pit to make baked naan.

[0003] However, the existing baked naan products still have some defects, and some other practical functions need to be improved. For example, most of the existing baked naan products are baked on iron plates. Since the baked naan has a certain thickness, if the iron plate is used for baking, it will take a lot of time and electricity, which is very environmentally unfriendly. In addition, the use of iron plates for baking will reduce the taste of the baked naan, and the flavor of the baked naan is different from the flavor of the baked naan made in the traditional earthen naan pit, thereby affecting the diners' experience. In addition, the efficiency of the existing baked naan products is low, the number of finished products baked at one time is small, and the functions are relatively single. Most of them only have the function of baking naan, and cannot bake other foods at the same time. Its versatility is poor, and it is not suitable for some places with large demand (schools, food courts, shops, etc.). Utility Model Content

[0038] Specifically, channel air inlets 1201 are opened on both sides of the hot air circulation channel 12, and a plurality of circulation air inlets 3081 are opened on the combustion chamber top cover 308.

[0039] The heating box 3 of the present invention also includes a hot air circulation blower 310, a hot air circulation outlet 311, and a burner assembly inspection port 312. The hot air circulation blower 310 is arranged on the left side of the burner assembly 303, the hot air circulation outlet 311 is opened on one side of the bottom of the heating box 3 and is opposite to the hot air circulation blower 310, and the burner assembly inspection port 312 is arranged on the other side of the bottom of the heating box 3.

[0040] Specifically, by opening the burner assembly inspection port 312 , the burner assembly 303 can be inspected and repaired regularly to ensure the normal operation of the burner assembly 303 .

[0041] The burner assembly 303 of the utility model includes a burner 3031, a burner air inlet pipe 3032, and an electric blower 3033. The burner 3031 is fixedly installed directly below the combustion chamber 304, one end of the burner air inlet pipe 3032 is connected to the burner 3031, and the other end of the burner air inlet pipe 3032 is connected to the electric blower 3033.

[0043] When the utility model is specifically implemented, refer to the attached Figure 3When the burner 3031 is working, it can spray high-temperature flames to the combustion chamber 304 directly above it through the cooperation with the burner air inlet pipe 3032 and the electric blower 3033. The high-temperature flames then form high-temperature hot air in the combustion chamber 304, which enters the heating chamber 305 through the plurality of air outlets 3021 on the air outlet plate 302, and is sprayed to the side of the insulation brick heating element 301 facing the heating chamber 305 to heat the insulation brick heating element 301. After being heated for a period of time, the insulation brick heating element 301 bakes the baked naan dough 3011 attached to the other side thereof through heat transfer;

[0044] When the utility model is specifically implemented, refer to the attached Figure 6 After the burner 3031 has been working for a period of time, the gas inside the heating box 3 will form high-temperature gas due to the high temperature inside the heating box 3. At this time, the hot air circulation blower 310 is in working state, and the hot air circulation blower 310 blows the high-temperature gas to the hot air circulation outlet 311, and the high-temperature gas flows from the hot air circulation outlet 311 to the first variable volume box 2 and the baking cavity 5, so as to perform secondary heating and baking on other types of food hung on the baking rack 201 in the first variable volume box 2 and the baked naan dough 3011 attached to the insulation brick heating element 301, thereby accelerating the baking rate, and then the high-temperature gas flows from the first variable volume box 2 and the baking cavity 5 into the hot air circulation channel 12 through the channel air inlet 1201, and then flows into the combustion chamber 304 through the circulation air inlet 3081.

[0047] Combined with Figure 1-7 The working principle of the combined environmental protection and energy-saving oven of the utility model is:

[0048] During operation, the pre-prepared baked naan dough 3011 is attached to the heat preservation brick heating element 301, and then the pulley 10 and the slide rail 6 are used to slide one baking unit assembly 1 to the other baking unit assembly 1, so that the second variable capacity box 4 on one baking unit assembly 1 is locked and connected with the first variable capacity box 2 on the other baking unit assembly 1 through the box body lock 7, and the inner cavity where the two meet forms a baking cavity 5. At this time, there are two rows of heat preservation brick heating elements 301 facing each other inside the baking cavity 5, and then the opening and closing button 902 on the connecting box body 9 is pressed to open. The baking unit assembly 1 is used to set the baking temperature and baking time required for the baked naan dough 3011 through the control panel 901, thereby starting to heat and bake the baked naan dough 3011 on the heat preservation brick heating element 301. After the set baking time is reached, the baking unit assembly 1 stops running, and at this time, the second variable capacity box 4 on one baking unit assembly 1 is separated from the first variable capacity box 2 on the other baking unit assembly 1 through the box body lock 7, thereby opening the baking cavity 5, and using a tool to remove the baked naan from the heat preservation brick heating element 301;

[0049] In addition, when it is necessary to bake different types of food other than baked naan at the same time, such as lamb legs, the lamb legs are hung on the baking rack 201 inside the first variable volume box 2 of one baking unit assembly 1, and the heat preservation brick heating element 301 inside the baking unit assembly 1 does not need to be attached with the baked naan dough embryo 3011, and the control panel 901 on the connecting box body 9 of the baking unit assembly 1 sets the baking time and baking temperature required for baking the lamb legs, and at the same time, the heat preservation brick heating element 301 inside the other baking unit assembly 1 is attached with the baked naan dough embryo 3011, and the control panel 901 on the connecting box body 9 of the baking unit assembly 1 sets the baking time and baking temperature required for baking the naan dough embryo 3011;

[0050] Several baking unit assemblies 1 of the utility model can be connected in pairs, and different types of food can be placed inside them through the cooperation of the baking rack 201 and the insulation brick heating element 301, and the baking temperature and baking time required for different types of food can be set through the control panel 901 on the connecting box 9 of each baking unit assembly 1, so as to realize the baking of different types of food at the same time. It has strong versatility and can meet the needs of some places with large demand (schools, food courts, shops, etc.).

[0051] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
