Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a chiffon cake oven. Background Art

[0002] Chiffon cake is a dessert, a type of sponge cake, made with vegetable oil, eggs, sugar, flour, baking powder, etc. However, due to the lack of the rich flavor of butter cake, chiffon cake usually requires a strong flavor of juice, or chocolate, fruit and other ingredients. Since vegetable oil is not as easy to foam as butter (traditional cakes are made with butter), it is necessary to beat the egg white into a foamy state to provide enough air to support the volume of the cake. Chiffon cake contains enough vegetable oil and eggs, so the texture is very moist, unlike traditional butter cakes that are easy to harden, chiffon cake also contains less saturated fat.

[0003] In the actual preparation process of chiffon cake, it is necessary to use an oven for heating and baking. The changes of chiffon cake in the oven are mainly divided into three stages: expansion, shaping, and browning. However, in the actual heating and baking process, it is found that since the heating elements of the current ovens generally use electric heating tubes to directly irradiate the surface of the chiffon cake, the chiffon cake is prone to produce smoke in the oven during the browning process due to high temperature and continuous baking. After the smoke is generated, it cannot be discharged to the outside in time. Since the chiffon cake itself has a porous structure, a small amount of smoke will be adsorbed in the chiffon cake, thereby affecting the taste of the chiffon cake. Therefore, the chiffon cake made using the existing ordinary oven often has a faint burnt smell.

[0004] In addition, the thermal insulation effect of existing ovens is average. During the actual baking process, the heat from the inner box overflows, causing the temperature of the outer shell of the oven to be higher, which not only causes heat overflow but also affects the user experience. Due to the heat overflow, the temperature between the inner box and the outer shell will also rise, which will seriously affect the service life of other electronic components installed in the oven, so improvement is needed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model proposes a chiffon cake oven. By designing the heating structure and the circulating air structure in the oven, the generation of smoke in the oven can be reduced, and the generated smoke can be adsorbed to prevent the smoke from dispersing in the oven, thereby improving the taste of the chiffon cake.

[0006] To realize the above technical scheme, the utility model provides a chiffon cake oven, comprising: an outer shell, a box door is installed on the front side of the outer shell, an inner box is installed in the outer shell, and the characteristic is that: a top light wave heating tube is installed on the inner side of the top of the inner box, a bottom light wave heating tube is installed on the bottom of the inner box, a transparent cover is installed above the bottom light wave heating tube, a circulating air back plate is installed on the back of the inner box, a plurality of circulating air inlet holes distributed side by side and spaced are respectively arranged on the top and bottom of the circulating air back plate, a smoke absorption module is installed in each circulating air inlet hole, an air distribution hole is arranged at the center of the circulating air back plate, a back sealing plate is installed behind the circulating air back plate, a circulating air cavity is enclosed between the circulating air back plate, the back sealing plate and the inner box, a circulating fan is installed on the back sealing plate, an impeller at the front end of the circulating fan is located in the circulating air cavity and is arranged opposite to the air distribution hole arranged on the circulating air back plate, a back electric heating tube is installed on the outer side of the circulating fan impeller, and an air inlet pipe connected to the outer side of the outer shell is arranged on the back sealing plate.

[0007] In the above technical solution, the heating structure adopts a heating method that combines light wave heating tubes and electric heating tubes, wherein the top light wave heating tubes and the bottom light wave heating tubes can directly heat the chiffon cake placed in the inner box. Compared with the traditional electric heating tubes that directly heat the chiffon cake, the chiffon cake can be heated for a longer time and the amount of smoke generated during the browning process of the chiffon cake can be reduced (experiments have shown that compared with the traditional electric heating tube direct heating, the amount of smoke generated when the chiffon cake is heated using light wave heating tubes is significantly reduced). In actual operation, a circulating air cavity is formed between the circulating air back plate and the back sealing plate, and the impeller of the circulating fan is installed in the circulating air cavity. An air intake pipe connected to the outside is arranged on the back sealing plate, and a plurality of circulating air inlet holes spaced side by side are arranged on the top and bottom of the circulating air back plate, and a smoke absorption module is installed in each circulating air inlet hole. Therefore, when the impeller of the circulating fan rotates, the external air is sucked into the circulating air cavity through the air intake pipe, and then heated by the back electric heating tube, and the heated air is blown out through the air distribution holes on the front side of the impeller of the circulating fan. The hot air is evenly transported to the inner box to ensure uniform air distribution. At the same time, the top light wave heating tube and the bottom light wave heating tube also work to heat the chiffon cake in the inner box and make the heat distribution in the top space and the bottom space of the inner box uniform. When the impeller rotates, part of the hot air and smoke in the inner box will be sucked back into the circulating air cavity through the circulating fan through the smoke absorption module installed in the circulating air inlet hole on the circulating air back plate, and then evenly transported to the inner box again through the air distribution hole, so as to realize the circulation of hot air, improve the efficiency of hot air and reduce energy consumption. When the circulating air passes through the smoke absorption module, the smoke absorbent loaded in the smoke absorption module can filter out the smoke in the circulating air to avoid the circulating air re-entering the inner box containing smoke, thereby preventing the smoke generated by the chiffon cake during the baking process from being dispersed in the oven, avoiding the smoke from being adsorbed in the chiffon cake, and improving the taste of the chiffon cake.

[0008] Preferably, the smoke absorption module comprises a box body, the surface of which is evenly provided with mesh holes, and the box body is filled with smoke absorbent. When the circulating air passes through the smoke absorption module, it first enters the box body from the mesh holes on the front surface of the box body, and after the smoke in the circulating air is filtered out by the smoke absorbent in the box body, it enters the circulating air cavity from the mesh holes arranged on other surfaces of the box body, thereby achieving the effect of smoke filtering.

[0009] Preferably, an overlap is provided on the front side of the box body, and after the box body is inserted into the circulating air inlet hole, it is tightly attached to the circulating air back plate through the overlap, so as to facilitate the insertion and replacement of the box body.

[0010] Preferably, two support rods extending horizontally backward are provided on the back of each circulating air inlet hole, and the smoke absorption module is inserted into the circulating air inlet hole and placed horizontally on the support rods to form good support for the smoke absorption module.

[0011] Preferably, a heat insulation cover consisting of a left-wrapped heat insulation board and a right-wrapped heat insulation board is installed on the outer side of the inner box body, a control panel is installed on the front top of the outer box body, the control panel and the inner box body are separated by the heat insulation cover, a display screen and control buttons are installed on the control panel, and the control panel and the inner box body are separated by the heat insulation cover, which can reduce the impact of spilled heat on the control panel and increase the service life of the control panel.

[0012] Preferably, the outer shell is enclosed by a frame, a left side panel, a top panel, a back panel, a right side panel and a bottom panel, and the left side, right side and top of the outer shell are separated from the inner box by a heat insulation cover, which can not only reduce the heat loss of the inner box, but also reduce the temperature of the outer shell.

[0013] Preferably, an electrical installation cavity is formed between the back sealing plate and the back plate of the outer shell, the control circuit board and the voltage stabilizer are respectively installed on the back sealing plate through the heat insulation seat and are located in the electrical installation cavity, a heat dissipation fan connected to the outer shell is installed in the electrical installation cavity, and heat dissipation holes are evenly opened on the back plate. By installing a heat insulation cover composed of a left-coated heat insulation board and a right-coated heat insulation board on the outer side of the inner box, the heat overflow of the inner box can be greatly reduced, and the temperature of the space between the outer shell and the inner box can also be reduced. It has a better heat insulation protection effect on the control circuit board, voltage stabilizer and other electronic components installed in the electrical installation cavity, and the control panel installed on the top of the front side of the outer shell, extending the service life of the electronic components. At the same time, with the heat dissipation fan installed in the electrical installation cavity, the temperature in the electrical installation cavity can be further reduced.

[0014] Preferably, a microwave heater is installed on the side wall of the inner box. In actual operation, the microwave heater can also be started as needed to perform microwave heating on the food placed in the inner box.

[0015] Preferably, a shelf is provided in the inner box to facilitate the placement of food plates.

[0016] Preferably, a handle is provided on the oven door, and a transparent viewing window is installed in the middle of the oven door. The handle facilitates opening or closing of the oven door, and the transparent viewing window facilitates observation of the baking status of food in the inner box.

[0017] The beneficial effects of a chiffon cake oven provided by the utility model are:

[0018] (1) The chiffon cake oven can reduce the generation of smoke in the oven by designing the heating structure and circulating air structure in the oven, and adsorb the generated smoke to prevent the smoke from dispersing in the oven, thereby improving the taste of the chiffon cake. The heating structure adopts a heating method combining light wave heating tubes and electric heating tubes, wherein the top light wave heating tubes and the bottom light wave heating tubes can directly heat the chiffon cake placed in the inner box. Compared with the traditional electric heating tubes directly heating the chiffon cake, the chiffon cake can be heated for a longer time and the amount of smoke generated during the browning process of the chiffon cake can be reduced. Through the structural design of the circulating air, when the circulating air passes through the smoke absorption module, the smoke in the circulating air is filtered out by the smoke absorbent in the box body, and then enters the circulating air cavity from the mesh holes set on other surfaces of the box body, thereby achieving the effect of smoke filtering, avoiding the circulating air re-entering the inner box containing smoke, thereby preventing the smoke generated during the baking process of the chiffon cake from dispersing in the oven, avoiding the smoke from being adsorbed in the chiffon cake, and improving the taste of the chiffon cake.

[0019] (2) This chiffon cake oven can avoid heat spillover from the inner box and improve thermal efficiency by installing a heat insulation cover between the inner box and the outer box, and combined with the design of the oven's heat dissipation structure, it can also reduce the impact of heat spillover on other electronic components installed in the oven. By installing a heat insulation cover consisting of a left-wrapped heat insulation board and a right-wrapped heat insulation board on the outside of the inner box, the heat spillover from the inner box can be greatly reduced, and the temperature of the space between the outer box and the inner box can also be reduced. It has a better heat insulation protection effect on the control circuit board, voltage stabilizer and other electronic components installed in the electrical installation cavity, as well as the control panel installed on the top of the front side of the outer box, extending the service life of the electronic components. At the same time, in conjunction with the cooling fan installed in the electrical installation cavity, the temperature in the electrical installation cavity can be further reduced.

[0031] Embodiment: A chiffon cake oven.

[0032] Reference Figures 1 to 9 As shown, a chiffon cake oven comprises: an outer shell 1, the outer shell 1 is enclosed by a frame 101, a left side plate 102, a right side plate 103, a back plate 104, a top plate 105 and a bottom plate 106, a control panel 2 is installed on the front top of the outer shell 1, a display screen 4 and control buttons 3 are installed on the control panel 2, so as to better set the working parameters of the oven, a flip-down door 5 is provided on the front side of the outer shell 1 below the control panel 2, a handle 7 is provided on the door 5, and a transparent visual window 6 is installed in the middle of the door 5, the handle 7 is provided to facilitate the opening or closing of the door 5, and the transparent visual window 6 is provided to facilitate the observation of the baking condition of the food in the inner box 19.

[0033] An inner box 19 is installed in the outer shell 1, a top light wave heating tube 21 is installed on the top of the inner box 19, a bottom light wave heating tube 24 is installed on the bottom of the inner box 19, and a transparent cover plate 23 is installed above the bottom light wave heating tube 24 to shield the bottom light wave heating tube 24. The heating of the top light wave heating tube 21 and the bottom light wave heating tube 24 can make the heating temperature distribution in the inner box 19 more uniform. In addition, the top light wave heating tube 21 and the bottom light wave heating tube 24 can directly heat the chiffon cake placed in the inner box 19. Compared with the traditional electric heating tube directly heating the chiffon cake, the chiffon cake can be heated for a longer time and the amount of smoke generated by the chiffon cake during the browning process can be reduced (experiments have shown that compared with the traditional electric heating tube direct heating, the amount of smoke generated in the oven is significantly reduced when the light wave heating tube is used to heat the chiffon cake).

[0034] The outer side of the inner box 19 is installed with a heat insulation cover composed of a left-wrapped heat insulation board 8 and a right-wrapped heat insulation board 9, and the left side, right side and top of the outer box 1 are separated from the inner box 19 by the heat insulation cover, which can not only reduce the heat loss of the inner box 19, but also reduce the temperature of the outer box 1 to prevent the user experience from being affected by the excessive temperature of the outer box 1. A shelf 22 is provided in the inner box 19 to facilitate the placement of food plates. A microwave heater 18 is installed on the side wall of the inner box 19. During actual operation, the microwave heater 18 can also be started as needed to perform microwave heating on the food placed in the inner box 19.

[0035] A circulating air back plate 20 is installed on the back of the inner box body 19, and a plurality of circulating air inlet holes 27 spaced side by side are respectively arranged on the top and bottom of the circulating air back plate 20, and two support rods 28 extending horizontally backward are arranged on the back of each circulating air inlet hole 27, and a smoke absorption module 26 is installed in each circulating air inlet hole 27, and the smoke absorption module 26 is inserted into the circulating air inlet hole 27 and placed horizontally on the support rods 28, and the smoke absorption module 26 includes a box body 261, and mesh holes 262 are evenly opened on the surface of the box body 261, and the box body 261 is filled with smoke absorbent, and a overlap 263 is arranged on the front side of the box body 261. After the box body 261 is inserted into the circulating air inlet hole 27, it is tightly attached to the circulating air back plate 20 through the overlap 263, and by setting the overlap 263, the box body 261 can be easily pulled out and inserted, and the overall replacement of the smoke absorption module 26 is convenient. An air distribution hole 25 is provided at the center of the circulating air back plate 20, and a back sealing plate 13 is installed behind the circulating air back plate 20. A circulating air cavity is enclosed between the circulating air back plate 20, the back sealing plate 13 and the inner box body 19. The circulating fan 15 is installed on the back sealing plate 13. The impeller at the front end of the circulating fan 15 is located in the circulating air cavity and is directly opposite to the air distribution hole 25 set on the circulating air back plate 20. A back electric heating pipe 12 is installed on the outer side of the impeller of the circulating fan 15. The back electric heating pipe 12 is used to heat the air in the circulating air cavity. An air inlet pipe 11 connected with the outer side of the outer shell 1 is provided on the back sealing plate 13. The air inlet pipe 11 is used to provide fresh air for heating the circulating air cavity. In actual operation, a circulating air cavity is formed between the circulating air back plate 20, the inner box body 19 and the back sealing plate 13, and the impeller of the circulating fan 15 is installed in the circulating air cavity, and an air inlet pipe 11 connected to the outside is arranged on the back sealing plate 13, and a plurality of circulating air inlet holes 27 arranged side by side and spaced apart are arranged on the top and bottom of the circulating air back plate 20, and a smoke absorption module 26 is installed in each circulating air inlet hole 27. Therefore, when the impeller of the circulating fan 15 rotates, the external air is sucked into the circulating air cavity through the air inlet pipe 11, and then heated by the back electric heating tube 12, and the heated air is blown out through the impeller through the front side of the impeller of the circulating fan 15. The air distribution holes 25 are evenly transported to the inner box 19 to ensure uniform air distribution. At the same time, the top light wave heating tube 21 and the bottom light wave heating tube 24 also work to heat the chiffon cake in the inner box 19 and make the heat distribution in the top space and the bottom space in the inner box 19 uniform. When the impeller rotates, part of the hot air and smoke in the inner box 19 will be re-sucked into the circulating air cavity through the circulating fan 15 through the smoke absorption module 26 in the circulating air inlet hole 27 installed on the circulating air back plate 20, and then evenly transported to the inner box 19 again through the air distribution holes 25, thereby realizing the circulation of hot air, so as to improve the hot air efficiency and reduce energy consumption.When the circulating air passes through the smoke absorption module 26, it first enters the box body 261 from the mesh 262 on the front surface of the box body 261, and after the smoke in the circulating air is filtered out by the smoke absorbent in the box body 261, it enters the circulating air cavity from the mesh 262 set on other surfaces of the box body 261, thereby achieving the effect of smoke filtering, avoiding the circulating air containing smoke when re-entering the inner box body 19, thereby preventing the smoke generated during the baking process of the chiffon cake from dispersing in the oven, avoiding the smoke from being adsorbed in the chiffon cake, and improving the taste of the chiffon cake.

[0036] An electrical installation cavity is formed between the back sealing plate 13 and the rear plate 104 of the outer shell 1. The control circuit board 17 and the voltage stabilizer 14 are respectively installed on the back sealing plate 13 through the heat insulation seat 16 and are located in the electrical installation cavity. A cooling fan 10 connected to the outer shell 1 is installed in the electrical installation cavity. The cooling fan 10 is used to reduce the temperature in the electrical installation cavity. A plurality of cooling holes are provided on the rear plate 104 of the outer shell 1 to further enhance the heat dissipation in the electrical installation cavity.

[0037] The chiffon cake oven can reduce the generation of smoke in the oven by designing the heating structure and circulating air structure in the oven, and adsorb the generated smoke to prevent the smoke from dispersing in the oven, thereby improving the taste of the chiffon cake. The heating structure adopts a heating method combining light wave heating tubes and electric heating tubes, wherein the top light wave heating tube 21 and the bottom light wave heating tube 24 can directly heat the chiffon cake placed in the inner box 19. Compared with the traditional electric heating tube directly heating the chiffon cake, the chiffon cake can be heated for a longer time and the amount of smoke generated by the chiffon cake during the browning process can be reduced. Through the structural design of the circulating air, when the circulating air passes through the smoke absorption module 26, the smoke in the circulating air is filtered out by the smoke absorbent in the box body 261, and then enters the circulating air cavity from the mesh 262 set on other surfaces of the box body 261, thereby achieving the effect of smoke filtering, avoiding the circulating air re-entering the inner box containing smoke, thereby preventing the smoke generated by the chiffon cake during the baking process from being dispersed in the oven, avoiding the smoke from being adsorbed in the chiffon cake, and improving the taste of the chiffon cake.

[0038] The chiffon cake oven can avoid the heat spillover of the inner box 19 and improve the thermal efficiency by installing a heat insulation cover between the inner box 19 and the outer box 1, and combined with the design of the heat dissipation structure of the oven, and can also reduce the influence of the heat spillover on other electronic components installed in the oven. By installing a heat insulation cover composed of a left-coated heat insulation board 8 and a right-coated heat insulation board 9 on the outer side of the inner box 19, the heat spillover of the inner box 19 can be greatly reduced, and the temperature of the space between the outer box 1 and the inner box 19 can also be reduced. It has a better heat insulation protection effect on the control circuit board 17, the voltage stabilizer 14 and other electronic components installed in the electrical installation cavity, and the control panel 2 installed on the top of the front side of the outer box 1, extending the service life of the electronic components. At the same time, in conjunction with the heat dissipation fan 10 installed in the electrical installation cavity, the temperature in the electrical installation cavity can be further reduced, and the overall heat dissipation effect of the oven can be enhanced.

[0039] The above is only a preferred embodiment of the present invention, but the present invention should not be limited to the contents disclosed in the embodiment and the drawings, so any equivalent or modification completed without departing from the spirit disclosed in the present invention shall fall within the scope of protection of the present invention.
