The casing 1 has an inner container 2, and the front side of the casing 1 has an inlet of the inner container 2. The door panel 3 is movably connected with the front side of the casing 1, and the movable connection can adopt a hinged connection or a sliding connection, so that the door panel 3 can cover or expose the inner container 2 of the casing 1, and a user can bake food in the inner container 2. After cooking is finished, the door panel 3 can be opened, so that the inner container 2 of the shell 1 is exposed, and food in the inner container 2 is taken out.

To facilitate the opening of the door panel 3, the oven 100 may further include a handle 4 as shown in fig. 2, and the handle 4 may be disposed at an outer side of the door panel 3. In this case, when food needs to be placed in the inner container 2, the user can pull the door plate 3 toward the front side of the outer shell 1 through the handle 4, and at this time, because the door plate 3 is movably connected with the outer shell 1, the door plate 3 can be opened toward the side far away from the inlet of the inner container 2, and the inner container 2 in the outer shell 1 is exposed. After the door plate 3 is opened, food can be placed in the inner container 2, the door plate 3 is pushed to the side close to the inlet of the inner container 2 through the handle 4, and therefore the door plate 3 covers the inlet of the inner container 2. Finally, oven 100 may be activated to cook the food within bladder 2. After the food is cooked, the food in the inner container 2 is taken out and the door plate 3 is closed according to the opening mode.

To achieve the heating function of the toaster 100, as shown in fig. 3, a heating element 5 may be installed in the liner 2, and the heating element 5 may be used to heat toasted food. The heating element 5 may be electrically connected to a power source (not shown in fig. 3) via a connector base, so that the heating element 5 is energized. When the food needs to be heated, the power supply can be switched on. After the food is baked, the power supply can be cut off.

In other embodiments of the present application, in order to make the temperature inside the oven 100 more stable and to control the heating temperature and the heating time, the oven 100 may further include a temperature sensor 6 and a control panel assembly 7 as shown in fig. 3. Wherein, the temperature sensor 6 and the control panel component 7 are electrically connected with a circuit between the heating element 5 and a power supply. By doing so, the temperature sensor 6 can measure the temperature in the heating chamber 21 to send to the control panel assembly 7, and the control panel assembly 7 can control the heating time and the heating temperature of the heater 5. In some embodiments of the present application, the control panel assembly 7 may be used not only as a display interface but also as an operation interface. In this case, the control panel assembly 7 may be disposed at the front side of the housing 1, and thus, when a user is at the front side of the oven 100, the operation parameters of the oven 100 may be set through the control panel assembly 7, and the operation state of the oven 100 may be observed through the control panel assembly 7. In other embodiments of the present application, the control panel assembly 7 may include a plurality of touch keys, and the operation state, the heating temperature, the operation time, and other functions of the oven 100 may be adjusted by touching the touch keys, which is very convenient.

In other embodiments of the present application, a plurality of knobs and buttons may be mounted on the front side of the housing 1 of the oven 100 to achieve the above-mentioned setting functions, and the heating temperature and the operation time of the oven 100 may be adjusted by the knobs or buttons. The terms of this adjustment are not limited in this application.

In order to facilitate cooking by the user, the oven 100 of the present application may further include a support rack 8 and a storage rack 9 as shown in fig. 4. The number of the supporting frames 8 may be one or more, and the structure of the supporting frame 8 is not limited in this application. The support frame 8 can form at least one limiting part along the left side and the right side of the side wall of the inner container 2. Wherein, two support frames 8 which are parallel relatively form a limiting part. When the limiting parts on the inner wall of the inner container 2 on the same side are in multiple layers, the left side and the right side of the side wall of the inner container 2 are provided with the limiting parts on the same layer, and the limiting parts on the same layer can be on the same horizontal plane for preventing food from sliding off. Thus, the shelf 9 for holding food can be inserted along the side of the support frame 8 near the outer side of the inner container 2 (i.e. the front side of the box) toward the inner side of the inner container 2. At this time, the same layer of the limiting part in the inner container 2 can support the object frame 9. When needs culinary art food, can draw out in can following inner bag 2 along support frame 8 earlier supporter 9, then place the food that needs the culinary art in supporter 9 top, food places the completion back, pushes away supporter 9 to inner bag 2 along support frame 8 once more in, treat that supporter 9 gets into behind inner bag 2 completely and can close door plant 3, at this moment, can start oven 100 and cook the work.

In other embodiments of the present application, the rack 9 may also be a vessel for carrying food, such as a bowl, a plate, a cup, etc. So, the user can directly place food in the household utensils, then place the household utensils on the supporter 9 in inner bag 2, under this condition, under the prerequisite of not taking out supporter 9, also can place food in inner bag 2. When cooking is carried out, the user is helped to select a proper vessel according to the requirement.

In other embodiments of the present application, as shown in fig. 5, a rotatable turntable 10 may also be installed at the bottom of the inner container 2, so that food can be prevented from being baked on the turntable 10, when the oven 100 is started, the turntable 10 can rotate at a certain rotation speed, in this case, the food placed on the turntable 10 is more uniformly baked with respect to the food prevented on the rack 9, and the amount of heat generated by heating each part of the food can be maximized and equalized, so that the occurrence of an unripe part of the food can be avoided when the food is locally scorched.

In order to increase the heating effect of the heating element 5, in other embodiments of the present application, the present application provides that the oven 100 may further include a reflector 11 and a reflective layer 12 as shown in fig. 6, and the heating element 5 for heating may include a light wave heating pipe 51 and a radiant heating pipe 52 as shown in fig. 7. Wherein, the inner container 2 has a heating cavity 21, the reflective cover 11 is connected with the inner wall of the heating cavity 21, the reflective cover 11 has an accommodating cavity, the accommodating cavity has an opening, and the opening is located on one side of the reflective cover 11 away from the heating cavity 21. The reflective layer 12 is disposed on the inner wall of the reflector 11. The optical wave heating tube 51 is installed in the heating cavity 21 and is located in the accommodating cavity. The radiant-heating pipe 52 is mounted in the heating chamber 21 and is located outside the reflection housing 11, a portion of the reflection housing 11 being located between the radiant-heating pipe 52 and the photo-wave heating pipe 51.

In this case, as shown in fig. 7, when the oven 100 is used, the switch of the oven 100 is turned on, the light wave heating pipe 51 inside the reflective cover 11 and the radiant heating pipe 52 outside the reflective cover 11 are energized, the light wave heating pipe 51 emits infrared rays, which are reflected to the food by the reflective layer 12 on the inner wall of the reflective cover 11, so as to directly heat the food, and the infrared rays have strong permeability, so that the food can be heated inside and outside the food at the same time, and the heated food has good taste. The radiant-heating pipe 52 heats the food in the heating chamber 21 by heat radiation, and the heating of the radiant-heating pipe 51 can be supplemented. The optical wave heating pipe 51 and the radiant heating pipe 52 are positioned inside the heating cavity 21 of the inner container 2, so that the external structure of the oven 100 is not changed, and the generalization of the existing platform is facilitated. The placement of the heating tube 51 in the heating chamber 21 improves the heat utilization efficiency of the heating tube 51, and the combined use of the heating tube 51 and the radiant-heating tube 52 can make the heating coverage area large.

In addition, since the heat radiation of the optical wave heating pipe 51 is strong, the service life of the surrounding radiation heating pipe 52 is affected. A portion of the reflector 11 is located between the heating tube 51 and the radiant-heating tube 52, so that the reflector 11 can isolate the heating tube 51 from the radiant-heating tube 52, so that the infrared rays of the heating tube 51 do not affect the radiant-heating tube 52.

The above mentioned structure of the reflective cover 11 is exemplified below, for example, in some embodiments of the present application, as shown in fig. 8, the reflective cover 11 has a bottom plate 111 and side plates 112 disposed around the bottom plate 111, and the side plates 112 and the bottom plate 111 enclose an accommodating cavity; the reflector 11 has a trapezoidal longitudinal section, and the bottom plate 111 is located on the short side of the trapezoid, and the longitudinal section is perpendicular to the bottom plate 111.

In this case, the bottom plate 111 may be connected to the inner wall of the heating cavity 21 in the oven 100, and the longitudinal section of the accommodating cavity formed by the side plates 112 and the bottom plate 111 disposed around the bottom plate 111 is trapezoidal, so that a part of the infrared rays emitted from the optical wave heating pipe 51 can be refracted to the food by the accommodating cavity. Therefore, infrared light rays emitted by the optical wave heating pipe 51 can irradiate on food, the infrared light rays are utilized to the maximum extent, and waste of the infrared light rays is avoided.

In order to prevent the temperature of the light wave heating pipe 51 from being too high, a high heat area is formed nearby, which affects the air exhausting and smoke exhausting effects, thereby affecting the taste of the baked food. In some embodiments of the present application, as shown in fig. 9, the bottom plate 111 is provided with a first through hole 1111, and the oven 100 further includes a communicating pipe 13, as shown in fig. 10, a portion of the communicating pipe 13 is located in the accommodating cavity, and another portion of the communicating pipe 13 passes through the first through hole 1111 and abuts against the inner container 2.

Thus, when oven 100 is operated, as shown in fig. 11, a part of heat in optical wave heating pipe 51 can be discharged out of heating chamber 21 along with communication pipe 13, so that the temperature of optical wave heating pipe 51 is not too high, which affects the taste of food, and the oil smoke generated by baking can also be discharged along with communication pipe 13. In some embodiments of the present application, since a portion of the communicating tube 13 is located in the heating cavity 21, the communicating tube 13 is made of a high temperature resistant material, for example, a metal ceramic composite material, and the metal ceramic composite material not only maintains the characteristics of high strength, high hardness, wear resistance, high temperature resistance, oxidation resistance, and chemical stability of ceramic, but also has good metal toughness and plasticity.

In order to enable the oil smoke in the heating cavity 21 to be discharged quickly, in some embodiments of the present application, the oven 100 may further include an air duct 14 and a fan 15 as shown in fig. 12, where the air duct 14 is disposed at the top of the inner container 2 and connected to the outer wall of the inner container 2, the air duct 14 includes an air inlet duct 141 and an air outlet duct 14, and the air inlet duct 141 is communicated with the communicating pipe 13. The fan 15 has an air inlet and an air outlet, the air inlet is communicated with the air inlet duct 141, and the air outlet is communicated with the air outlet duct 142.

In this case, the air in the heating chamber 21 flows into the air intake duct 141 through the communicating pipe 13, and the air intake opening of the blower 15 communicates with the air intake duct 141. Therefore, under the driving of the fan 15, the air flows into the fan 15 from the air inlet duct 141, and then flows into the air outlet duct 142 communicating with the air outlet of the fan 15. Under the driving of the fan 15, the gas in the heating cavity 21 can quickly take away the heat in the heating cavity 21, so as to reduce the temperature inside the oven 100 within a controllable range, reduce the damage to the electrical components inside the oven 100, and prolong the service life of the oven 100.

Since the oven 100 generates a certain amount of oil smoke when cooking food, if the oil smoke is directly discharged into the room, the quality of air in the room is affected. Therefore, the oven 100 according to the embodiment of the present application may further include a smoke filter 16 as shown in fig. 12, where the smoke filter 16 is disposed outside the inner container 2 and is communicated with the communicating pipe 13.

In some embodiments of the present disclosure, the smoke filter 16 may be a catalyst, wherein the catalyst can catalyze the odor component in the smoke, so that the odor component in the smoke reacts to generate the odorless substance under the action of the catalyst. When food in the heating cavity 21 is heated, when oil smoke generated by the food enters the communicating pipe 13, the oil smoke can react with the catalyst in the communicating pipe 13, so that peculiar smell components such as organic aldehyde, organic acid, organic amine and organic ester generated when the food is baked can generate tasteless substances along with the catalysis of air flow and the catalyst, and then the air is discharged from the air outlet duct 142 through the fan 15. Thus, the purification effect of the discharged gas is realized to reduce the amount of the odor component diffused into the room, and the stimulation to the user is reduced. In addition, because the catalyst is located in the communicating pipe 13, the catalyst does not occupy the use space of the inner container 2, which is convenient for increasing the effective use space of the oven 100.

The above-mentioned catalyst is exemplified below, for example, in some embodiments of the present application, the catalyst includes one or more alumina ceramics, and when the number of the alumina ceramics is plural, the plural alumina ceramics may be arranged in parallel with each other. In the process of passing through the alumina ceramic, the high-temperature oil smoke can be subjected to oxidation catalytic reaction under the catalysis of the alumina ceramic (platinum is used as a catalyst). In other embodiments, the alumina ceramic can be replaced by an alumina ceramic honeycomb plate, and when the alumina ceramic honeycomb plate is adopted, the contact area of the oil fume and the alumina ceramic is larger, so that better oxidation catalysis effect can be obtained.

In some other embodiments of the present application, the catalyst may include one or more molecular sieve honeycomb panels, and when the number of the molecular sieve honeycomb panels is plural, the plural molecular sieve honeycomb panels may be arranged in parallel with each other. The molecular sieve can also be used as a catalyst for the oil smoke to generate catalytic oxidation reaction, so that the high-temperature oil smoke can also generate oxidation catalytic reaction in the process of passing through the molecular sieve honeycomb plate.

In order to prevent the user from touching the optical wave heating tube 51 and causing injury when using the oven 100, in some embodiments of the present application, the oven 100 may further include a shielding case 17 as shown in fig. 13, where the shielding case 17 covers the opening of the accommodating cavity of the reflective case 11 and is connected to a circumference of the reflective case 11. The isolation cover 17 may be one of a quartz plate, a microcrystalline plate, a mesh plate, and a metal mesh. The light of the optical wave heating pipe 51 in fig. 11 is transmitted through the shielding case 17 to the outside of the containing chamber to be irradiated onto the food.

In this case, when the door 3 of the oven 100 is opened after the food is baked, the isolation cover 17 is cooled quickly, which can prevent the user from being scalded, and the isolation cover 17 in the present application does not obstruct the light wave heating pipe 51 from passing through. In addition, the isolation cover 17 can prevent the heating temperature of the optical wave heating pipe 51 from being too high, which affects the electric components outside the oven 100.

The above-mentioned optical wave heating tube 51 is exemplified below, for example, in some embodiments of the present application, the optical wave heating tube 51 may be arranged in a straight shape to cook food. However, when baking food, the baking tray for holding food is placed the position and greatly influences the uniformity of baking, the level near the optical wave heating tube 51 is generally poor in uniformity, and cannot be compatible with the conventional heating tube, the arrangement mode of the optical wave heating tube 51 and the reflector 11 cannot be compatible with a heat dissipation and smoke removal system, and because the temperature of the optical wave heating tube 51 is high, the optical wave heating tube 51 cannot work for a long time, and the mode heating efficiency of intermittent operation is not high.

Based on this, as shown in fig. 14, the optical wave-heating pipe 51 may include at least a first infrared-heating pipe 511 and a second infrared-heating pipe 512. The first infrared heating pipe 511 is wound in a circular arc shape, the second infrared heating pipe 512 is arranged around the first infrared heating pipe 511 in a circular arc shape near the outer periphery of the reflection cover 11, and the reflection cover 11 is in a circular truncated cone shape.

The first infrared heating pipe 511 and the second infrared heating pipe 512 are arc-shaped, so that the uniformity of irradiation and heating is improved; meanwhile, different energization times of the first infrared heating pipe 511 and the second infrared heating pipe 512 can be controlled through program setting, so that the uniformity of temperature can be further improved, and higher baking requirements can be met.

Specifically, the first infrared heating pipe 511 and the second infrared heating pipe 512 may have the same structure, and have a simple overall structure and low cost. In other embodiments, the first infrared heating tube 511 and the second infrared heating tube 512 are not limited to circular arc shapes, and may have other similar ring structures such as polygonal shapes.

To illustrate the dimensions of the first and second infrared heating pipes 511 and 512 more clearly, in some embodiments of the present application, the inner container 2 of the oven 100 has a mounting surface 22 as shown in fig. 10, and the mounting surface 22 is a top wall of the inner container 2. The bottom plate 111 of the reflection housing 11 is mounted on the mounting surface 22, the mounting surface 22 is rectangular, the mounting surface 22 has a first side length D (in the y direction shown in fig. 10) and a first side length W (in the x direction shown in fig. 10), the first infrared heating pipe 511 has a first diameter D1, and the second infrared heating pipe 512 has a second diameter D2.

Wherein the minimum value min (D, W) of the first side length D and the first side length W, and the first diameter D1 and the second diameter D2 satisfy the following formula:

min(D,W)/d2＝1.4～1.6；d2/d1＝1.2～1.4。

in this case, the power of the second infrared heating pipe 512 is 1.2 times or more the power of the first infrared heating pipe 511. In this way, the first infrared heating pipe 511 and the second infrared heating pipe 512 are sized to match the mounting surface 22 of the inner container 2 of the oven 100. If the sizes of the first and second infrared heating pipes 511 and 512 are too small, the amount of generated infrared rays will be insufficient to cook food, and if the sizes of the first and second infrared heating pipes 511 and 512 are too large, not only is material wasted, but also infrared rays may not completely cover food since food is generally placed in the middle of the heating chamber 21 during heating.

In some embodiments of the present application, the material of the first infrared heating tube 511 and the second infrared heating tube 512 may be graphene, carbon fiber, tungsten wire heating tube, or the like. The present application is not limited to such a heating tube as long as the heating tube can emit infrared rays.

The radiant-heating pipe 52 mentioned above is exemplified below, for example, in some embodiments of the present application, as shown in fig. 15, the mounting surface 22 of the inner container 2 of the oven 100 may be square, and the radiant-heating pipe 52 is disposed in a square shape around a circumference of the mounting surface 22. Thus, the radiant-heating pipe 52 is matched with the mounting surface 22, so that the temperature in the inner container 2 of the oven 100 can be better raised, and the food can be better heated. The radiant heating pipe 52 may be made of a metal heating pipe, specifically, a stainless steel heating pipe.

Thus, the stainless steel heating pipe is made of metal material, so that the stainless steel heating pipe can resist dry burning. The stainless steel heating pipe can be filled with high-temperature-resistant insulating magnesium oxide powder, and has the characteristics of insulating property and safety in use. The stainless steel electric heating tube has extremely strong plasticity and can be bent into various shapes. The stainless steel electric heating tube has high controllability, can adopt different wiring modes and temperature control, and has high automatic control.

In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
