Description

Technical Field

[0001] The utility model belongs to the technical field of cooking equipment, and specifically relates to an oven. Background Art

[0002] With the continuous development of oven technology and the continuous improvement of users' requirements for product performance, ovens with a smoking function have gradually emerged. During the baking process of the oven, by providing smoke into the oven cavity, the food in the cavity has a smoked flavor, meeting the user's need to obtain food with a smoked flavor.

[0003] Chinese Patent with publication number CN217772092U discloses an oven. A smoking module is arranged outside the working cavity of the oven. The smoking module includes a smoke generation unit that can generate smoke as needed. The smoke generation unit includes a smoking material box and an electric heater arranged in the smoking material box. The smoking material box includes an inner shell and an outer shell of the smoking material box that are plugged into each other. A feeding port is arranged on the tube wall of the inner shell of the smoking material box. Users can put smoking material blocks or smoking material powder into the inner shell of the smoking material box through the feeding port. The inner shell of the smoking material box is installed on the installation part of the front panel at the top of the oven main body in a push-pull manner. Users can conveniently pull out the inner shell of the smoking material box to add smoking material blocks.

[0004] Although the oven with the above structure arranges the smoking module outside the working cavity of the oven to avoid occupying the inner cavity space, however, the amount of smoking material that the inner shell of the smoking material box can hold is small, the smoke generation amount is limited, and its applicability in the baking oven is low.

[0061] Figures 1 to 7 An embodiment of the oven of the present utility model is shown, in which, Figures 1 to 3 is a perspective view of the oven of this embodiment at different angles, Figure 4 and Figure 6 are respectively a longitudinal cross-sectional schematic diagram and a transverse cross-sectional schematic diagram of this embodiment, Figure 5 is Figure 4 an enlarged view of part A of Figure 7 is a partial structural schematic diagram of this embodiment.

[0062] As Figures 1 to 7 shown, the oven of this embodiment includes an outer housing (not shown in the figure), an inner housing 10 and a smoking module 20. The inner housing includes a left side plate 11, a right side plate 12, a back plate 13, a top plate 14 and a bottom plate 15. The left side plate 11, the right side plate 12, the back plate 13, the top plate 14 and the bottom plate 15 enclose a working cavity 16 of the oven for accommodating food ingredients. An opening 17 is formed in the front of the working cavity 16, and this opening 17 is a channel for food ingredients to enter and exit the working cavity 16, and the opening 17 can be opened / closed by the door body of the oven.

[0063] The smoking module 20 is fixed on the outer housing and / or the inner housing, and it includes a feeding assembly 21, a smoke generating assembly 23 and a smoke outlet part 24.

[0064] The feeding assembly 21 includes a feeding cylinder 211. One end of the feeding cylinder 211 forms a feeding port 2111, and the other end forms a discharging port 2112. Among them, the feeding port 2111 is located on or exposed outside the outer housing, facilitating the user to put the smoking material for generating smoke through the feeding port 2111 outside the oven. The discharging port 2112 is located inside the outer housing and is communicated with the smoke generating assembly 23. Furthermore, the smoking material put in from the feeding port 2111 can enter the smoke generating assembly 23 through the feeding cylinder 211. In some embodiments, the feeding cylinder 211 is in a bent shape inclined downward. Setting the feeding cylinder 211 in a bent shape inclined downward makes the inner cavity volume of the feeding cylinder 211 larger, capable of accommodating more smoking materials, reducing the number of times of putting in smoking materials, and reducing user operations; the feeding cylinder 211 inclined downward enables the smoking material to smoothly enter the smoke generating assembly 23 from the discharging port 2112 by gravity.

[0065] In some other embodiments, the feeding assembly 21 further includes a feeding cover for opening / closing the feeding port 2111. During the process of needing to put in smoking materials or during the smoking and baking operation, the feeding cover opens the feeding port 2111, and the smoking material can be put in from the feeding port 2111, or air can be introduced from the feeding port 2111 into the smoke generating assembly 23. When the smoking and baking operation stops, the feeding cover can be used to close and block the feeding port 2111 to prevent sundries from entering and improve the appearance beauty of the oven.

[0066] The smoke generating assembly 23 is located between the outer housing and the inner housing 10. It has a smoke generating cavity 231. A material placing rack 232 is arranged in the smoke generating cavity 231, and a heating device 233 is arranged at the bottom of the material placing rack 232. The discharging port 2112 is communicated with the smoke generating cavity 231, and the smoking material enters the material placing rack 232 from the discharging port 2112. In some embodiments, to increase the volume of the smoke generating cavity 231, the material placing rack 232 is arranged at the bottom of the smoke generating cavity 231. In some embodiments, the heating device 233 is a heating tube, and the heating tubes are dispersedly arranged at the bottom of the material placing rack 232 to improve the heating uniformity and make full use of the smoking material on the material placing rack 232 to generate smoke.

[0067] The smoke outlet part 24 is close to the working cavity 16 of the oven. Specifically, it is located between the working cavity 16 and the smoke generating cavity 231 and is communicated with the working cavity 16 and the smoke generating cavity 231 respectively. The smoke generated by heating the smoking material on the material placing rack 232 by the heating device 233 in the smoke generating cavity 231 enters the working cavity 16 from the smoke outlet part 24 to smoke the food materials in the working cavity 16.

[0068] In this embodiment, the smoking module 20 is fixed to the outer casing and / or the inner casing. The feed inlet 2111 of the feed cylinder 211 is provided on the outer casing of the oven or exposed outside the outer casing. The smoking material required for smoking and producing smoke can be directly put in through the feed inlet 2111, and enters the material placement rack 232 in the smoke production chamber 231 through the feed cylinder 211. Under the heating action of the heating device 233, smoke is produced. The smoke enters the working chamber 16 of the oven through the smoke outlet 24 for smoking. Using the smoking module 20 of this embodiment, no components need to be moved when putting in the smoking material, and it can be directly put in through the feed inlet 2111 and the feed cylinder 211. It can also be put in at any time during the smoke production process without being restricted. It is convenient to use, can control the smoke production amount at any time, and there will be no problems such as low safety caused by taking out high-temperature smoke production components for putting in the smoking material and environmental pollution caused by the dispersion of smoke outside. In addition, the feed assembly 21 and the smoke production assembly 23 are basically independent of each other in structure, which is convenient to set their respective structures to provide a larger amount of smoke production to meet different smoking requirements of the oven, and improves the practicability of the smoking module 20 in the oven.

[0069] As Figure 5 shown, the smoke outlet 24 is located at the upper part of the smoke production chamber 231, away from the material placement rack 232, so as to facilitate fully introducing the smoke in the smoke production chamber 231 into the working chamber 16. The smoke outlet 24 includes the housing 241 of the smoke outlet. The housing 241 of the smoke outlet protrudes into the working chamber 16 from the side of the smoke production chamber 231 close to the inner casing 10, forming a smoke outlet buffer chamber 242. The smoke inlet of the smoke outlet buffer chamber 242 faces the smoke production chamber 231. A plurality of smoke outlet holes 243 are formed on the housing 241 of the smoke outlet. Specifically, the smoke outlet holes 243 are formed on the housing of the upper end face in the housing 241 of the smoke outlet. The smoke from the smoke production chamber 231 first enters the smoke outlet buffer chamber 242, then flows upward, and enters the working chamber 16 through the smoke outlet holes 243 on the upper end face. Using the smoke outlet buffer chamber 242 and the smoke outlet holes 243 of the smoke outlet 24 to form a smoke outlet channel, so that the smoke production chamber 231 and the working chamber 16 do not directly conduct smoke convection, which can prevent the smoke in the working chamber 16 from flowing back into the smoke production chamber 231 and affecting the smoking effect.

[0070] In some other embodiments, the smoke outlet 24 is a smoke outlet opened on the inner casing 10 and corresponding to the position of the smoke production chamber 231.

[0071] To realize the control of the smoking material from the feed assembly 21 entering the smoke production assembly 23 to realize the control of the smoke production amount, in this embodiment, the smoking module 20 further includes a feeding assembly 22, which is located between the feed cylinder 211 and the smoke production assembly 23 and is used to send the material discharged from the discharge port 2112 to the material placement rack 232.

[0072] See Figure 1 、 Figure 6As shown, the feeding assembly 22 includes a feeding housing 221, a feeding motor 223, a rotating shaft 224, and a spiral blade 225. The feeding housing 221 defines a feeding cavity 222. The feeding cavity 222 is respectively communicated with the discharge port 2112 of the feeding cylinder 211 and the smoke generating cavity 231. That is, the discharge port 2112 of the feeding cylinder 211 is communicated with the smoke generating cavity 231 through the feeding cavity 222. Moreover, the discharge port 2112 is located at one end of the feeding cavity 222 away from the smoke generating assembly 23. The feeding motor 223 is arranged on the feeding housing 221 and is located at one end close to the discharge port 2112. In this embodiment, the smoke generating assembly 23 is located at the front end close to the opening 17 of the inner housing 10, the feeding assembly 22 is located behind the smoke generating assembly 23, and both the discharge port 2112 and the feeding motor 223 are located at the rear end of the feeding cavity 222. The rotating shaft 224 is at least partially located in the feeding cavity 222, and one end of it located in the feeding cavity 222 close to the feeding motor 223 is connected to the feeding motor 223, specifically connected to the output shaft of the feeding motor 223, and rotates under the action of the feeding motor 223. The spiral blade 225 is formed on the rotating shaft 224 and can rotate following the rotation of the rotating shaft 224, and conveys the material discharged into the rear end of the feeding cavity 222 from the discharge port 2112 forward, and finally sends it to the material placing rack 232 through the front end of the feeding cavity 222. In Figure 6 In the structure shown, most of the rotating shaft 224 and the spiral blade 225 are located in the feeding cavity 222, and a part of them extends out of the feeding cavity 222 and enters the smoke generating cavity 231, which can send the smoking material to the material placing rack 232 as evenly as possible, make full use of the heating device 233, and improve the smoke generating efficiency.

[0073] By setting the feeding assembly 22 including the feeding motor 223, the amount of the smoking material entering the material placing rack 232 can be controlled by controlling the rotation speed of the feeding motor 223, and then the automatic and quantitative control of the smoke generating amount of the smoke generating assembly 23 can be realized by controlling the amount of the smoking material, so as to meet the different requirements of different food materials and / or different smoking degrees for the smoke generating amount, and realize the intelligent smoking control of the oven.

[0074] Moreover, by driving the rotating shaft 224 and the spiral blade 225 with the feeding motor 223 and sending the smoking material to the material placing rack 232 through the rotation of the spiral blade 225, it is beneficial to slowly and evenly place the smoking material in the feeding cavity 222 on the material placing rack 232, make the smoke generation in the smoke generating assembly 23 more uniform, improve the utilization rate of the smoking material and heat, and further improve the smoke generating efficiency.

[0075] In some other embodiments, the feeding assembly is implemented by the following structure:

[0076] The feeding assembly includes a feeding housing, a driving mechanism, a telescopic rod, and a pushing plate. For the structure of the feeding housing, refer to Figure 6As shown, it defines a feeding cavity, and the feeding cavity is respectively communicated with the discharge port of the feeding cylinder and the smoke generating cavity. The driving mechanism is arranged on the feeding housing and is located at one end close to the discharge port. The driving mechanism can be a motor, or a hydraulic driving mechanism, a pneumatic driving mechanism, etc. The telescopic rod is at least partially located in the feeding cavity, and the end thereof located in the feeding cavity and close to the driving mechanism is connected to the driving mechanism, and can be telescoped under the drive of the driving mechanism. The pushing plate is connected to the telescopic rod, specifically, it can be connected to the other end of the telescopic rod away from the driving mechanism. The pushing plate moves back and forth in the feeding cavity following the telescopic movement of the telescopic rod, and sends the material discharged into the feeding cavity from the discharge port to the material placing rack through the feeding cavity.

[0077] For the feeding assembly adopting the above structure, by controlling the telescopic speed of the telescopic rod by the driving mechanism, the feeding speed of the smoking material can be controlled, the control of the amount of the smoking material can be realized, and further the smoke generating speed and the amount of generated smoke can be controlled to meet the different requirements of different food materials and / or different smoking degrees for the amount of generated smoke, and the intelligent smoking control of the oven can be realized.

[0078] After smoking, there will be ash residues in the smoke generating cavity 231, especially on the material placing rack 232. To clean the ash residues in a timely and automatic manner, the smoking module 20 further includes a cleaning assembly 25 for supplying cleaning water to the smoke generating cavity 231 to clean the smoke generating cavity 231.

After the smoking is completed, the water pump 253 is controlled to start, and the cleaning water in the water tank 251 is sent to the smoke generating cavity 231 through the water pipe 252 to clean the smoke generating cavity 231, and the cleaned outflow enters the collection box 256 from the smoke generating cavity 231, so as to realize the water washing and cleaning of the smoke generating cavity 231.

[0080] The collection box 256 can be set to be composed of a housing and an inner container body. The inner container body is located inside the housing, and the outflow of the smoke generating cavity 231 is collected in the inner container body. The inner container body can be taken out and placed into the oven. For example, in some embodiments, the inner container body is taken out and put into the oven in a drawer structure. The inner container body of the collection box 256 is taken out, the ash residues collected therein are poured out, and the cleaned inner container body is put back into the oven to continue collecting the ash residues.

[0081] The water tank 251 can be configured to be composed of a housing and an inner tank body. The inner tank body is located inside the housing, and the cleaning water is placed in the inner tank body. The inner tank body can be taken out from and put into the oven. For example, in some embodiments, the inner tank body of the water tank 251 is taken out from and put into the oven in a drawer-type structure. When the cleaning water in the inner tank body of the water tank 251 is insufficient, the inner tank body of the water tank 251 can be taken out, the cleaning water can be added, and then it can be put back into the oven.

[0082] To achieve the compactness of the entire smoking module, both the water tank 251 and the collection box 256 are in the shape of long strip boxes, and extend from the front end to the rear end of the oven along the front-rear direction of the oven.

The spray head 254 is close to the material placement rack 232. The cleaning water is sprayed onto the material placement rack 232 through the spray head 254, increasing the flushing area and flushing force, and improving the cleaning cleanliness of the ash on the material placement rack 232.

[0084] In this embodiment, the material placement rack 232 is inclined relative to the horizontal plane, and a collection groove 234 is formed in the smoke generation chamber 231. The collection groove 234 is located at the bottom end position of the material placement rack 232. The cleaning assembly 25 further includes a drainage pipe 255. One end of the drainage pipe 255 communicates with the smoke generation chamber 231, specifically with the collection groove 234 in the smoke generation chamber 231, and the other end communicates with the collection box 256, specifically near the collection inlet 257 of the collection box 256, and communicates with the collection box 256 through the collection inlet 257. By inclining the material placement rack 232 and arranging the collection groove 234 at its bottom end position, it is convenient for the ash after cleaning to smoothly enter the collection groove 234 along the inclined plane for collection and summary, and then be drained into the collection box 256 through the drainage pipe 255 for collection, avoiding the ash from remaining on the surface of the material placement rack 232, and improving the cleaning efficiency and cleaning cleanliness.
