Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to an infrared oven with a cleaning function. Background Technology

[0002] Ovens, especially chicken ovens, are mainly used for roasting chicken, chicken legs, chicken wings and other delicacies, and have gradually become one of the commonly used cooking equipment in the catering industry.

[0003] In existing technologies, the heat source of ovens mainly uses charcoal as fuel or metal heating elements. The heat source is converted into hot air through fan blades, and heating mainly relies on hot air convection. However, traditional ovens require a long baking time and have significant energy loss. They also do not achieve good browning of food, making it difficult to meet the requirements of a crispy exterior and tender interior. At the same time, traditional ovens lack automatic cleaning functions. The internal accessories of the oven cavity need to be manually removed, soaked, and cleaned, which is cumbersome. The internal walls of the oven cavity can only be wiped with wet cloths and scouring pads, resulting in low cleaning efficiency and requiring a lot of manpower. Utility Model Content

[0004] Therefore, it is necessary to provide an infrared oven with a cleaning function to address the problems of poor baking effect, high energy loss and lack of automatic cleaning function in existing ovens.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An infrared oven with a cleaning function includes a housing, an oven cavity inside the housing, a rotating baking tray assembly installed inside the oven cavity, food fixed on the rotating baking tray assembly, the food rotating under the drive of the rotating baking tray assembly, and a far-infrared lamp assembly installed on the inner top wall of the housing, the far-infrared lamp assembly generating infrared radiation when energized, thereby baking the food rotated by the rotating baking tray assembly;

[0007] A cleaning mechanism is installed at the bottom of the oven cavity to clean the inside of the oven cavity after baking.

[0008] As a further improvement to the above technical solution:

[0009] The cleaning mechanism has the following structure: it includes a liquid supply main pipe, a fixed pipe is installed on the outer circumference of the liquid supply main pipe, the axis of the fixed pipe is parallel to the radial direction of the liquid supply main pipe, the fixed pipe is installed concentrically with the connecting pipe through a bearing, a cleaning spray pipe is fixed at the end of the connecting pipe, the axis of the cleaning spray pipe is perpendicular to the axis of the connecting pipe, a spray hole is opened on the outer circumference of the cleaning spray pipe, and a spray head is installed at each end of the cleaning spray pipe.

[0010] Cleaning fluid is introduced into the main supply pipe, and the cleaning fluid enters the cleaning nozzle in sequence through the fixed pipe and the connecting pipe. The cleaning fluid in the cleaning nozzle is sprayed out through the spray hole and two nozzles. At the same time, the cleaning nozzle rotates relative to the fixed pipe under the action of the hydraulic pressure of the cleaning fluid.

[0011] The box body is provided with a water collection tank, and a baffle assembly is installed above the water collection tank. The baffle assembly includes two oil collection baffles symmetrically arranged opposite the liquid supply main pipes. Each oil collection baffle is arranged at an angle, so that the liquid in the furnace cavity collects and flows into the water collection tank. A drain pipe is installed in the water collection tank to discharge the liquid in the water collection tank.

[0012] The end of the liquid supply main pipe is fitted with a T-connector, through which water and cleaning agent are injected into the liquid supply main pipe respectively.

[0013] A hot air circulation mechanism is installed on the top wall of the box, which causes the air inside the furnace cavity to circulate up and down.

[0014] The structure of the hot air circulation mechanism is as follows: it includes a return air baffle and a first air outlet baffle that are fixed at intervals to the top wall of the box.

[0015] The return air baffle is spaced apart from the inner top wall of the box, thereby forming a return air space between the return air baffle and the inner top wall of the box;

[0016] The first air outlet baffle is spaced apart from the inner top wall of the box, thereby forming an air outlet space between the first air outlet baffle and the inner top wall of the box. The air outlet space is connected to the air duct assembly arranged on the outer top wall of the box. A fan assembly is installed in the air duct assembly and the fan assembly is arranged facing the return air space.

[0017] The air inside the furnace cavity is circulated through the return air space and the air duct assembly under the action of the fan assembly. The air in the outlet air space is then blown back into the furnace cavity, thus forming a circulation.

[0018] Several return air holes are provided on the return air baffle, and the air in the furnace cavity enters the return air space through the return air holes.

[0019] A second air outlet baffle is arranged on one side of the first air outlet baffle. The second air outlet baffle is arranged at an angle to disturb the air flowing out of the air outlet space.

[0020] A lamp tube baffle is arranged below the far-infrared lamp tube assembly, and several through holes are opened on the lamp tube baffle.

[0021] The infrared radiation generated by the far-infrared lamp assembly heats and bakes the food through the perforation.

[0022] The rotating baking pan assembly is mounted on the outer circumferential surface of the rotating shaft. The end of the rotating shaft extends to the outside of the housing and is connected to the output end of the drive motor. The drive motor drives the rotating shaft to rotate, thereby causing the rotating baking pan assembly to rotate.

[0023] The beneficial effects of this utility model are as follows:

[0024] This utility model has a compact and reasonable structure and is easy to operate. By setting up a far-infrared lamp tube assembly, it can bake food based on infrared radiation without the need for heat transfer medium. It has low thermal inertia, rapid heating, and can effectively save energy. Infrared radiation has penetrating power and can heat the inside and outside simultaneously. It has high thermal conductivity and can effectively improve the baking effect. At the same time, by setting up a cleaning mechanism, it can automatically clean the inside of the oven cavity, effectively improving cleaning efficiency.

[0025] This utility model also has the following advantages:

[0026] (1) By setting a fixed pipe, a connecting pipe and a bearing, a rotary connection between the liquid supply pipe and the cleaning nozzle can be realized, so that when the cleaning liquid in the liquid supply pipe enters the cleaning nozzle, the cleaning nozzle can be driven to rotate relative to the liquid supply pipe based on natural hydraulic pressure, effectively expanding the cleaning range of the cleaning mechanism, thereby realizing the all-round cleaning of the furnace cavity.

[0027] (2) By setting up an inclined water collection tank and an inclined oil collection baffle, waste liquid can be collected quickly and effectively after cleaning.

[0028] (3) By setting up a drain pipe and installing the drain pipe at the low position of the water collection tank, the liquid in the water collection tank can flow naturally to the drain pipe along the inclined direction of the water collection tank, making it convenient to discharge and empty the liquid in the water collection tank.

[0029] (4) By setting up a hot air circulation mechanism, the air inside the oven cavity can be circulated, thereby improving the temperature uniformity inside the oven cavity and enabling the food on the rotating baking tray to be baked evenly.

[0030] (5) By setting a second air outlet baffle, the air blown out through the strip opening can be bounced back to achieve air disturbance.

[0031] (6) By setting up a drive motor and a rotating shaft, the food can be rotated by rotating the baking pan assembly during baking, thereby further improving the baking uniformity. Attached Figure Description

[0042] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0043] The structure and function of this utility model are as follows:

[0044] like Figures 1-7As shown, an infrared oven with a cleaning function includes a housing 1, inside which is an oven cavity. A rotating baking tray assembly 5 is installed within the oven cavity, on which food is fixed. The food rotates under the influence of the rotating baking tray assembly 5. A far-infrared lamp assembly 2 is installed on the inner top wall of the housing 1. When energized, the far-infrared lamp assembly 2 generates infrared radiation, thereby baking the food rotated by the rotating baking tray assembly 5. A cleaning mechanism 9 is installed at the bottom of the oven cavity to clean the interior of the oven cavity after baking. By using the far-infrared lamp assembly 2, food can be baked based on infrared radiation, eliminating the need for a heat transfer medium. It has low thermal inertia, rapid heating, and effectively saves energy. Infrared radiation has penetrating power, heating both inside and outside simultaneously, and has high thermal conductivity, effectively improving the baking effect. Simultaneously, the cleaning mechanism 9 automatically cleans the interior of the oven cavity, effectively improving cleaning efficiency.

[0045] The oven body 1 is fitted with a door 4. When the oven is working, the door 4 is closed; when the door 4 is open, food can be taken out of the oven cavity or put into the oven cavity.

[0046] In this invention, the far-infrared lamp assembly 2 includes several far-infrared lamps. Each far-infrared lamp generates infrared radiation by inserting a tungsten filament into a gas-filled quartz tube and heating the tungsten filament with an alternating voltage, thereby heating the gas in the quartz tube.

[0047] A lamp tube baffle 7 is arranged below the far-infrared lamp tube assembly 2, and several through holes 8 are opened on the lamp tube baffle 7; the infrared radiation generated by the far-infrared lamp tube assembly 2 heats and bakes the food through the through holes 8. By setting the lamp tube baffle 7, the far-infrared lamp tube assembly 2 can be protected.

[0048] like Figure 7As shown, the structure of the cleaning mechanism 9 is as follows: it includes a liquid supply main pipe 901, a fixed pipe 905 is fitted on the outer circumference of the liquid supply main pipe 901, the axial direction of the fixed pipe 905 is parallel to the radial direction of the liquid supply main pipe 901, the fixed pipe 905 is concentrically installed with the connecting pipe 906 through a bearing, the end of the connecting pipe 906 is fixed with a cleaning nozzle 903, the axial direction of the cleaning nozzle 903 is perpendicular to the axial direction of the connecting pipe 906, a spray hole 904 is opened on the outer circumference of the cleaning nozzle 903, and a nozzle is fitted on both ends of the cleaning nozzle 903 respectively; cleaning fluid is introduced into the liquid supply main pipe 901, and the cleaning fluid enters the cleaning nozzle 903 in sequence through the fixed pipe 905 and the connecting pipe 906, and the cleaning fluid in the cleaning nozzle 903 is sprayed out through the spray hole 904 and the two nozzles, and at the same time, the cleaning nozzle 903 rotates relative to the fixed pipe 905 under the action of the cleaning fluid hydraulic pressure. The oven features a cleaning function, allowing the oven cavity to be rinsed and cleaned using a splash-type water source, significantly reducing manual labor. By incorporating a fixed pipe 905, a connecting pipe 906, and bearings, a rotatable connection can be established between the main liquid supply pipe 901 and the cleaning nozzle 903. This allows the cleaning fluid from the main liquid supply pipe 901 to enter the cleaning nozzle 903, enabling the nozzle to rotate relative to the main liquid supply pipe 901 based on natural hydraulic pressure. This effectively expands the cleaning range of the cleaning mechanism 9, thereby improving the cleaning effect.

[0049] The housing 1 is equipped with a water collection tank 11, and a baffle assembly is installed above the water collection tank 11. The baffle assembly includes two oil collecting baffles 10 symmetrically arranged opposite the liquid supply main pipe 901. Each oil collecting baffle 10 is inclined, so that the liquid in the furnace cavity collects and flows into the water collection tank 11. A drain pipe 12 is installed in the water collection tank 11 to drain the liquid in the water collection tank 11. In this utility model, the bottom wall of the water collection tank 11 is inclined. By setting the inclined water collection tank 11 and the inclined oil collecting baffles 10, waste liquid can be collected quickly and effectively after cleaning. By setting the drain pipe 12 and installing the drain pipe 12 at the low position of the water collection tank 11, the liquid in the water collection tank flows naturally along the inclined direction of the water collection tank 11 to the drain pipe 12, which facilitates the discharge and emptying of the liquid in the water collection tank 11.

[0050] A T-connector 902 is installed at the end of the liquid supply main pipe 901. Water and cleaning agent are injected into the liquid supply main pipe 901 through the T-connector 902. The T-connector 902 has three interfaces: the first interface is connected to the end of the liquid supply main pipe 901, the second interface is connected to the water supply end, and the third interface is connected to the cleaning agent supply end. Tap water is supplied to the liquid supply main pipe 901 through the water supply end via the T-connector 902, and cleaning agent is supplied to the liquid supply main pipe 901 through the T-connector 902. The cleaning agent and tap water mix to form a cleaning solution.

[0051] A hot air circulation mechanism 3 is installed on the top wall of the oven body 1, which causes the air inside the oven cavity to circulate up and down. By setting up the hot air circulation mechanism 3, the air inside the oven cavity can be circulated, thereby improving the temperature uniformity inside the oven cavity, and thus enabling the food on the rotating baking tray assembly 5 to be baked evenly.

[0052] like Figures 2-5 As shown, the hot air circulation mechanism 3 has the following structure: it includes a return air baffle 303 and a first air outlet baffle 306 fixed at intervals on the inner top wall of the housing 1; the return air baffle 303 is spaced apart from the inner top wall of the housing 1, thereby forming a return air space 304 between the return air baffle 303 and the inner top wall of the housing 1; the first air outlet baffle 306 is spaced apart from the inner top wall of the housing 1, thereby forming an air outlet space 308 between the first air outlet baffle 306 and the inner top wall of the housing 1, the air outlet space 308 is connected to the air duct assembly arranged on the outer top wall of the housing 1, and a fan assembly is installed in the air duct assembly, the fan assembly is arranged facing the return air space 304; the air in the furnace cavity, under the action of the fan assembly, passes through the return air space 304 and the air duct assembly in sequence and enters the air outlet space 308, and the air in the air outlet space 308 is blown back into the furnace cavity, thereby forming a circulation. The fan assembly includes at least one fan 301, and the duct assembly includes at least one duct 302. The duct 302 and the fan 301 are arranged in a one-to-one correspondence. In this utility model, two fans 301 are arranged, and correspondingly, two ducts 302 are arranged.

[0053] Several return air holes 305 are provided on the return air baffle 303, through which air from the furnace cavity enters the return air space 304. By providing the return air holes 305, the return air space 304 can be connected to the internal space of the furnace cavity.

[0054] A second air outlet baffle 307 is arranged beside the first air outlet baffle 306. The second air outlet baffle 307 is arranged at an angle to disturb the air flowing out of the air outlet space 308. In this utility model, a strip-shaped opening is provided on one side of the first air outlet baffle 306. The air outlet space 308 is connected to the internal space of the furnace cavity through the strip-shaped opening. The air introduced into the furnace cavity by the fan assembly is blown out through the strip-shaped opening. The second air outlet baffle 307 is arranged beside the strip-shaped opening to reflect the air blown out through the strip-shaped opening, thereby achieving air disturbance.

[0055] The rotating baking tray assembly 5 is mounted on the outer circumferential surface of the rotating shaft 13. The end of the rotating shaft 13 extends outside the housing 1 and is connected to the output end of the drive motor 6. The drive motor 6 drives the rotating shaft 13 to rotate, thereby causing the rotating baking tray assembly 5 to rotate. In this invention, the rotating baking tray assembly 5 includes at least two turntables. Each turntable is fitted with components such as a rotisserie fork and a baking basket (not shown in the accompanying drawings) to suspend food on the corresponding baking tray, thus securing the food. By configuring the drive motor 6 and the rotating shaft 13, the food can be rotated by the rotating baking tray assembly 5 during baking, thereby further improving the uniformity of baking.

[0056] The working process of this utility model is as follows:

[0057] First, the food is fixed on the rotating baking tray assembly 5, and the drive motor 6 is started to drive the rotating shaft 13 to rotate, thereby rotating the food through the rotating baking tray assembly 5; at the same time, the far-infrared lamp tube assembly 2 is started to generate far-infrared radiation, and the fan assembly is started to bake the food in the oven cavity.

[0058] After baking, the food is removed, and the cleaning mechanism 9 is activated. First, the cleaning solution formed by mixing the cleaning agent with tap water enters the cleaning spray pipe 903 through the three-way connector 902, the main supply pipe 901, the fixed pipe 905, and the connecting pipe 906. The cleaning solution in the cleaning spray pipe 903 is sprayed out through the spray hole 904 and two nozzles.
