Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a self-cleaning oven. Background Technology

[0002] An oven is a sealed appliance used to bake food or dry products. It uses radiant heat emitted by electric heating elements to bake food. During the baking process, the oil in the food tends to evaporate. Because the oven's internal space is sealed, the oil will adhere to the inner walls of the oven. Over time, the amount of oil residue inside the oven will increase.

[0003] Traditional restaurant steam ovens do not have an automatic cleaning function, so the inside of the oven needs to be cleaned manually. This is not only time-consuming and labor-intensive, but also has the problem of generally poor cleaning results. Summary of the Invention

[0013] Optionally, the gas heating assembly includes:

[0014] A centrifugal fan is installed in the housing, and the air inlet is located in the centrifugal fan;

[0015] An air duct is connected to the centrifugal fan, and the air outlet is located in the air duct; and

[0016] A heating wire is wound around the outer periphery of the air duct, and the heating wire is used to heat the air duct and the air inside the air duct.

[0017] Optionally, the self-cleaning oven further includes a conveying connector, which has a first pipe and a second pipe. The first pipe connects the air duct and the spray pipe, and the diameters at both ends of the first pipe are larger than the diameter at its middle. The second pipe connects the middle part of the first pipe and the atomizing pipe.

[0018] Optionally, the self-cleaning oven further includes a one-way valve embedded in the atomizing pipe to deliver water mist unidirectionally toward the spray pipe.

[0019] Optionally, the self-cleaning oven further includes a solenoid valve located in the atomizing pipeline to open or close the atomizing pipeline.

[0020] Optionally, the spray assembly includes:

[0021] A spray plate is provided in the cavity. The top of the spray plate has spray holes, the spray channel is provided inside the spray plate, and the spray plate also has drainage holes that penetrate the upper and lower end faces.

[0022] A water collection tray is located below the spray tray. The water collection tray has a water collection cavity with an opening at the top, which is used to collect water flowing through the drain hole.

[0023] Optionally, the spray disc includes:

[0024] The support plate, wherein the drainage hole is provided on the support plate;

[0025] A spray head is disposed on the upper surface of the support plate. The spray head has a frustum structure, and the outer diameter of the spray head decreases in the direction away from the support plate. The spray holes are disposed on the side wall of the spray head.

[0026] Optionally, the spray plate includes a baffle body disposed on the upper end face of the support plate and extending around the periphery of the upper end face. The baffle body abuts against the side wall of the chamber. The upper end of the baffle body has an inclined surface that extends close to the support plate in the direction toward the spray head.

[0029] Compared with the prior art, in the technical solution of this invention, the self-cleaning oven includes a cabinet with a cavity for placing food. A gas heating component is installed on the cabinet, having an air inlet and an air outlet. External air enters the gas heating component through the air inlet, is heated to a temperature higher than the boiling point of water, and then exits through the air outlet. A spraying component is installed inside the cavity of the self-cleaning oven, having a spraying channel and spray holes facing the inner wall of the cavity. The spraying channel and spray holes are connected. The self-cleaning oven also includes a spray pipe connecting the air outlet of the gas heating component and the spraying channel. This allows high-temperature air exiting the air outlet to enter the spraying channel through the spray pipe and exit through the spray holes. Additionally, the self-cleaning oven also includes... The oven has an atomizer and an atomizing pipe. The atomizer is located on the housing and contains liquid water. The atomizer atomizes the liquid water to produce water mist. The atomizing pipe connects the atomizer and the spray pipe. At the connection point between the atomizing pipe and the spray pipe, the diameter of the spray pipe decreases along the air delivery direction. When the high-temperature air passes through this connection point, the air velocity increases due to the reduced diameter of the spray pipe, creating a low pressure at the connection point. This pressure adsorbs the water mist in the atomizing pipe, drawing it into the spray pipe and transporting it to the spray assembly with the high-temperature air. During this process, the water mist absorbs heat from the high-temperature gas to generate steam, which is then ejected from the spray holes. The ejected steam continuously washes the inner wall of the chamber, dissolving the grease on the inner wall and thus cleaning the oven. In this technical solution, steam is used to clean the oven cavity, which not only solves the problem of ovens being difficult to clean, but also helps to improve the efficiency and effectiveness of oven cleaning.

[0046] An oven is a sealed appliance used for baking food or drying products. During baking, the oil in the food often evaporates. Because the oven's interior is sealed, the oil adheres to the inner walls, accumulating more and more grease over time. Traditional restaurant steam ovens lack automatic cleaning functions, requiring manual cleaning, which is time-consuming, labor-intensive, and often ineffective.

[0047] To solve the above-mentioned technical problems, this technical solution proposes a self-cleaning oven, comprising:

[0048] Box 100, with a cavity inside for placing food;

[0049] A gas heating component 200 is installed in the housing 100 and has an air inlet and an air outlet. External air enters the gas heating component 200 through the air inlet, is heated to a temperature higher than the boiling point of water, and then is discharged through the air outlet.

[0050] The spray assembly 300 is disposed in the chamber, and the spray assembly 300 has spray holes facing the inner wall of the chamber and spray channels communicating with the spray holes.

[0051] The spray pipe 400 connects the air outlet and the spray channel to guide the air to the spray channel;

[0052] Atomizer 500, located in housing 100, is used to generate water mist; and

[0053] Atomizing pipe 600 connects to atomizer 500 and spray pipe 400;

[0054] At the connection point between the spray pipe 400 and the atomizing pipe 600, the diameter of the spray pipe 400 decreases along the air delivery direction to draw water mist into the spray pipe 400.

[0055] Compared with the prior art, in the technical solution of this invention, the self-cleaning oven includes a housing 100, which has a cavity for placing food. A gas heating component 200 is installed on the housing 100, having an air inlet and an air outlet. External air enters the gas heating component 200 through the air inlet, is heated to a temperature higher than the boiling point of water, and then exits through the air outlet. A spray component 300 is installed inside the cavity of the self-cleaning oven, having a spray channel and spray holes facing the inner wall of the cavity. The spray channel and spray holes are connected. The self-cleaning oven also includes a spray pipe 400, which connects the air outlet of the gas heating component 200 and the spray channel. Thus, high-temperature air exiting the air outlet can enter the spray channel through the spray pipe 400 and be sprayed out through the spray holes. Additionally, the self-cleaning oven also includes an atomizer 50. 0 and atomizing pipe 600, wherein the atomizer 500 is mounted on the housing 100, and the atomizer 500 contains liquid water, which is atomized to produce water mist. The atomizing pipe 600 connects the atomizer 500 and the spray pipe 400, and at the connection point between the atomizing pipe 600 and the spray pipe 400, the diameter of the spray pipe 400 decreases along the air delivery direction. Thus, when the high-temperature air passes through this connection point, due to the spray pipe 400 As the pipe diameter decreases, the airflow velocity increases, creating low pressure at the connection point. This low pressure then adsorbs the water mist within the atomizing pipe 600, drawing it into the spray pipe 400. From there, the water mist is transported with the high-temperature air to the spray assembly 300. During this process, the water mist absorbs heat from the high-temperature gas, generating steam. This steam is then ejected from the spray holes, continuously washing the inner wall of the oven cavity to dissolve grease and thus clean the oven. In this technical solution, using steam to clean the oven cavity not only solves the problem of ovens being difficult to clean but also improves the efficiency and effectiveness of oven cleaning.

[0056] Specifically, such as Figures 1 to 8The self-cleaning oven includes a housing 100 with an interior chamber. An opening is located on one side of the chamber, and a door is rotatably connected to the opening. Food to be baked can be placed inside the chamber through the opening. A gas heating element 200 is located on the back side of the housing 100 opposite the opening. The gas heating element 200 can be a device that heats air, such as a hot air blower. The gas heating element 200 has an air inlet and an air outlet. External air enters the gas heating element 200 through the air inlet, is heated to a temperature higher than the boiling point of water, and then discharged through the air outlet. In addition, the self-cleaning oven also includes a spray assembly 300, which is disposed within the cavity of the housing 100. The spray assembly 300 can be a conical or spherical structure, etc., and is fixed to the bottom wall of the cavity. The spray assembly 300 has spray holes, and multiple spray holes can be arranged around its outer periphery. These spray holes are inclined towards the side and top walls of the cavity. A spray pipe 400 is also provided inside the spray assembly 300 and communicates with the spray holes. The self-cleaning oven also includes a spray pipe. The spray pipe 400 can be located on the same side of the self-cleaning oven as the gas heating component 200. The spray pipe 400 can be made of high-temperature resistant materials such as metal, high-temperature resistant plastic or high-temperature resistant composite material. One end of the spray pipe 400 is connected to the air outlet of the gas heating component 200, and the other end extends into the interior of the aforementioned chamber and is connected to the spray pipe 400 of the spray component 300. In this way, the high-temperature air generated by the gas heating component 200 can be transported to the spray component 300 through the spray pipe 400 and sprayed towards the inner wall of the chamber from the spray holes on the spray component 300. In addition, the self-cleaning oven also includes an atomizer 500 and an atomizing pipe 600. The atomizer 500 is located on the outside of the oven body 100. To reduce operating noise, the atomizer 500 can be an ultrasonic atomizer 500. In this embodiment, the atomizer 500 includes an atomizer 500 body and a water container. The atomizer 500 body is provided with an outlet and an inlet. The water container can be connected to the inlet to supply liquid water into the atomizer 500 body. The liquid water entering the atomizer 500 body is atomized and then discharged from the outlet. In addition, an atomizing pipe 600 is provided at the outlet. The atomizing pipe 600 can be made of the same high-temperature resistant material as the spray pipe 400. One end of the atomizing pipe 600 is connected to the outlet of the atomizer 500, and the other end is connected to the spray pipe 400. In this technical solution, the connection position of the spray pipe 400 and the atomizing pipe 600 forms a T-shaped three-way structure. At this connection position, the diameter of the spray pipe 400 gradually decreases along its air delivery direction. The atomizing pipe 600 is connected to a position with a smaller diameter near the spray pipe 400.In practical use, when the high-temperature air from the spray pipe 400 passes through the connection point, the air velocity increases due to the reduced diameter of the spray pipe 400. According to the Venturi principle, a low-pressure area is generated at the connection point. Since the pressure in the atomizing pipe 600 is greater than the pressure in this low-pressure area, the water mist in the atomizing pipe 600 is drawn into the spray pipe 400 and transported towards the spray assembly 300 with the high-temperature air. Because the air temperature is greater than the water mist temperature, the air and water mist mix and exchange heat. The water mist is heated to form steam. Due to the vaporization of the water mist, the pressure in the spray pipe 400 further increases and is sprayed out through the spray assembly 300, creating a scouring effect on the inner wall of the chamber. In addition, the steam also heats and dissolves the oil stains on the inner wall of the chamber. The dissolved oil stains are detached from the inner wall surface with the liquefied steam and flow to the bottom wall of the chamber, thus cleaning the chamber. In this technical solution, the Venturi effect is created by changing the diameter of the spray pipe 400, which in turn draws in the water mist from the atomizing pipe 600 and heats it to form steam. Finally, the steam is used to clean the inner wall of the cavity. This solution has the advantages of simple structure and easy implementation. The cleaning process does not require manual intervention, which helps to save manpower. In addition, steam cleaning has a better cleaning effect and higher cleaning efficiency than traditional cleaning methods at room temperature.

[0057] Furthermore, the gas heating assembly 200 includes:

[0058] Centrifugal fan 210 is located in housing 100, and air inlet is located in centrifugal fan 210;

[0059] Air duct 220, connected to centrifugal fan 210, with air outlet located in air duct 220; and

[0060] Heating wire 230 is wound around the outer periphery of air duct 220 and is used to heat air duct 220 and the air inside air duct 220.

[0061] Specifically, such as Figure 2 and Figure 3In this embodiment, the gas heating assembly 200 includes a centrifugal fan 210, which is fixedly connected to the back side wall of the housing 100 by screws. Compared with ordinary axial flow fans, the centrifugal fan 210 is thinner, which is more conducive to reducing the overall volume of the self-cleaning oven. The centrifugal fan 210 has an air inlet and an air outlet, wherein the air inlet is located on the side face away from the housing 100, and the air outlet is located on the side wall of the centrifugal fan 210. In addition, a guide pipe 220 is attached to the air outlet, and the air is discharged from the outlet. The airflow can enter the air guide duct 220, which is a circular tube structure. The air guide duct 220 can be made of materials with good thermal conductivity, such as quartz or metal. The outer periphery of the air guide duct 220 is wrapped with heating wire. During operation, the heating wire will heat the air guide duct 220, which will heat the airflow flowing through it, thereby heating the air. In addition, the end of the air guide duct 220 away from the centrifugal fan 210 is connected to the spray pipe 400, thereby guiding the heated air into the spray pipe 400.

[0062] Furthermore, the self-cleaning oven also includes a conveyor connector 700, which has a first pipe and a second pipe. The first pipe connects to the air duct 220 and the spray pipe 400, and the diameters at both ends of the first pipe are larger than the diameter in the middle. The second pipe connects to the middle of the first pipe and the atomizing pipe 600. Specifically, as shown... Figure 4 The self-cleaning oven also includes a conveyor connector 700, which is a T-shaped three-way pipe structure. The conveyor connector 700 has a first pipe and a second pipe. The first pipe is an hourglass-shaped structure with a small diameter in the middle and large diameters at both ends. The second pipe connects to the small-diameter section in the middle of the first pipe and is perpendicular to the first pipe. To ensure operational reliability, the conveyor connector 700 can be made of high-temperature resistant materials such as metal. In use, the second pipe of the conveyor connector 700 can be sleeved or threaded through the atomizing pipe 6. The first pipe can be connected to the air duct 220, and the other end of the first pipe can be connected to the spray pipe 400. The water mist in the atomizing pipe 600 can enter the delivery joint 700 and mix with the air in the air duct 220, and then be delivered to the spray pipe 400. The delivery joint 700 facilitates the connection of the air duct 220, the spray pipe 400 and the atomizing pipe 600, and also facilitates the flexible disassembly of components such as the atomizing pipe 600, the gas heating component 200 and the spray pipe 400 for maintenance.

[0063] Furthermore, the self-cleaning oven also includes a one-way valve 800, which is embedded in the atomizing pipe 600 to deliver water mist in one direction toward the spray pipe 400. Figure 2 and Figure 5To ensure the reliability of the self-cleaning oven, a one-way valve 800 is also provided. This one-way valve 800 can be located within the atomizing pipe 600. In this embodiment, the one-way valve 800 includes an outer sleeve fitted onto the atomizing pipe 600. A valve body is provided on the inner wall of the outer sleeve. The valve body has a conical structure made of a soft material such as silicone or rubber. The tip of the conical body faces the direction of water mist delivery, and the conical body faces the atomizer 50. A conical groove can be opened on the end face of 0, and a vent can be opened at the tip of the cone. The vent is connected to the conical groove. When water mist is delivered to the spray pipe 400, the water mist can pass through the vent. When the pressure on the side of the valve body facing the spray pipe 400 is greater than that on the other side, the end face of the valve body facing the spray pipe 400 can be compressed and deformed, so that the vent is closed, thereby preventing the high temperature air of the spray pipe 400 from flowing back into the atomizer 500, ensuring the reliability of the operation.

[0064] Furthermore, the self-cleaning oven also includes a solenoid valve 900, which is located in the atomizing tube 600 to open or close the atomizing tube 600. For example... Figure 2 The self-cleaning oven also includes a solenoid valve 900, which is located on the atomizing pipe 600 and used to control the opening and closing of the atomizing pipe 600. Through the setting of the solenoid valve 900, the self-cleaning oven can have two working modes: spraying steam or spraying high-temperature air into the cavity. By spraying steam, the oil stains on the inner wall of the cavity can be dissolved. When using the high-temperature air spraying mode, the heating temperature of the heating wire 230 can be adjusted so that the air is heated to the thermal decomposition temperature of the oil stains (400℃~500℃). By heating the cavity with high-temperature air, the oil stains in the cavity are thermally decomposed, which can also achieve the effect of cleaning the oven.

[0065] Optionally, the spray assembly 300 includes:

[0066] Spray plate 310 is located in the chamber. Spray holes are opened on the top of spray plate 310. Spray channels are located inside spray plate 310. Drainage holes are also opened through the upper and lower end faces of spray plate 310. Spray plate 310 is slidably connected to the inner wall of the chamber and is detachably connected to spray pipe 400.

[0067] A water collection tray 320 is located below the spray tray 310. The water collection tray 320 has a water collection cavity with an opening at the top, which is used to collect water flowing through the drain hole.

[0068] like Figures 6-8In this embodiment, the spray assembly 300 includes a spray plate 310 and a water collection plate 320. The spray plate 310 is located in the chamber near the bottom wall. A slide rail can be provided on the side wall of the chamber, and the spray plate 310 can be slidably connected to the slide rail. In addition, the spray plate 310 and the spray pipe 400 can be detachably connected by means of plug-in or other means. By making the spray plate 310 detachable, the space occupied by the spray plate 310 in the chamber can be reduced, and the cleaning and maintenance of the spray plate 310 before and after use can be facilitated. In addition, spray holes can be opened on the top of the spray plate 310, and spray channels can be set inside the spray channels. Furthermore, a drain hole is also opened on the spray plate 310, which runs through the upper and lower end faces of the spray plate 310. The water collection plate 320 is set below the spray plate 310, and a slide rail can be set on the lower end face of the spray plate 310. The water collection plate 320 can be slidably connected to the slide rail. In this way, during the cleaning process, the spray plate 310 can collect the oil and liquid water dripping from the chamber, and then collect them in the water collection plate 320 after draining through the drain hole. This can prevent the oil from further contaminating the bottom wall of the chamber and further improve the cleaning effect.

[0069] Furthermore, the spray plate 310 includes:

[0070] Support plate 311, with drainage holes provided on support plate 311;

[0071] Spray head 312 is located on the upper end face of support plate 311. Spray head 312 has a frustum structure and the outer diameter of spray head 312 decreases in the direction away from support plate 311. Spray holes are located on the side wall of spray head 312.

[0072] In addition, the spray plate 310 also includes a baffle 313, which is disposed on the upper end face of the support plate 311 and extends around the perimeter of the upper end face. The baffle 313 abuts against the side wall of the chamber. The upper end of the baffle 313 has an inclined surface, which extends close to the support plate 311 in the direction toward the spray head 312.

[0073] like Figure 7 In this embodiment, the spray plate 310 includes a support plate 311, which is a plate-shaped structure. The upper surface of the support plate 311 is provided with a spray head 312, which is a frustum-shaped structure. The end of the spray head 312 connected to the support plate 311 is the end with a larger outer diameter. Spray holes are opened on the side wall of the spray head 312, and multiple spray holes are arranged side by side at intervals along the central axis of the spray head 312. The angle between each spray hole and the upper surface of the support plate 311 is different, so that the steam can be sprayed out at different angles from each spray hole, thereby achieving a larger area coverage of the inner wall of the cavity. Alternatively, multiple spray holes can be arranged at intervals along the circumference of the spray head 312 to achieve the same effect.

[0074] Furthermore, the self-cleaning oven also includes a pressure relief valve 1000, which is connected to the spray pipe 400 to control the pressure within the spray pipe 400. For example... Figure 2 To ensure the reliability of the self-cleaning oven, a pressure relief valve 1000 is also provided on the spray pipe 400. The pressure relief valve 1000 is connected to the spray pipe 400 and can be set with a maximum threshold. When the pressure in the spray pipe 400 reaches the threshold, the pressure relief valve 1000 opens to release pressure, controlling the pressure in the spray pipe 400 so that it does not become too high, thereby ensuring the reliability of the self-cleaning oven and also helping to extend the service life of the self-cleaning oven.

[0075] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
