A heater in a traditional oven is generally exposed in an inner container, a large amount of oil stains can be agglutinated on the surface of the heater and in the inner container when food is cooked, and the surface of the heater and the inner container shielded by the heater are not easy to clean. It is also prone to damage when the heater is impregnated with oil.

Therefore, the embodiment of the present application provides an oven 100, as shown in fig. 1, the oven 100 may include a door panel 1, a housing 2, and a liner 3 located in the housing 2, where the liner 3 is used for a user to place food for cooking, the housing 2 is movably connected to the door panel 1, and the door panel 1 may rotate relative to the housing 2, so as to cover an inlet of the liner 3, and thus the liner 3 forms a sealed cavity. The door panel 1 can be far away from the entrance of the inner container 3, so that the inner container 3 is exposed for placing food.

As shown in fig. 1, when a user uses the oven 100, a side of the oven 100 having the door panel 1 is defined as a front side. The user can open the door panel 1 at the front side of the oven 100 to expose the inner container 3, and after food is placed in the inner container 3, the user can press the oven 100 to start the switch by closing the door panel 1, so that the oven 100 can bake the food. After the food is cooked, the door panel 1 is opened to take out the food.

In order to facilitate the opening of the door panel 1, in some embodiments of the present application, as shown in fig. 2, the oven 100 may further include a handle 4, the handle 4 is installed at an outer side of the door panel 1, in this case, when food needs to be placed in the inner container 3, a user may pull the door panel 1 toward a front side of the outer container 2 through the handle 4, and at this time, due to the movable connection between the door panel 1 and the outer container 2, the door panel 1 may be opened toward a side away from the entrance of the inner container 3, exposing the inner container 3 in the outer container 2. After the door plate 1 is opened, food can be placed in the inner container 3, the door plate 1 is pushed to the side close to the inlet of the inner container 3 through the handle 4, and therefore the door plate 1 covers the inlet of the inner container 3. Finally, oven 100 may be activated to cook the food within bladder 3. After the food is cooked, the food in the inner container 3 is taken out and the door panel 1 is closed according to the opening mode.

In order to facilitate cooking by the user, in some embodiments of the present application, as shown in fig. 3, the oven 100 may further include a shelf 5. The shelf 5 can be fixed on the inner wall of the inner container 3 of the oven 100, and can also be movably connected with the inner wall of the inner container 3. This supporter 5 puts the thing face and is on a parallel with the diapire of inner bag 3, so, supporter 5 puts the thing face and is in horizontal position, more conveniently bears food. When the volume of inner bag 3 is less, because the space in the inner bag 3 is limited, consequently, can fix supporter 5 inside inner bag 3 this moment, during the culinary art food, directly place food on supporter 5 can. In other embodiments of the present application, if the volume of the inner container 3 of the oven 100 is large, the space in the inner container 3 is large, so that at this time, if the rack 5 is fixed with the inner container 3, food cannot be placed in the deep part of the inner container 3, and the space in the inner container 3 cannot be effectively utilized. Consequently, can set swing joint to with 3 inner walls of supporter 5 and inner bag, during the culinary art food, can slide earlier supporter 5 by inner bag 3 and take out, then place food on supporter 5, slide supporter 5 at last and place and cook in inner bag 3.

In other embodiments of the present application, as shown in fig. 3, the toaster 100 may include a tray for carrying a vessel 6 for holding food, such as a bowl, plate, cup, etc. In this way, the user can directly place food in the household utensils 6, then place household utensils 6 on the supporter 5 in inner bag 3, under this condition, under the prerequisite that does not take out supporter 5, also can place food in inner bag 3. When cooking is carried out, the user is helped to select a suitable vessel 6 according to the requirements.

In other embodiments of the present application, as shown in fig. 4, a rotatable turntable 7 may also be installed at the bottom of the inner container 3, so that food can be placed on the turntable 7, when the oven 100 is started, the turntable 7 can rotate at a certain rotation speed, in this case, the food placed on the turntable 7 is more uniformly baked with respect to the food on the rack 5, and the amount of heat applied to each part of the food can be maximally equalized, so as to avoid the occurrence of an uncooked part of the food in the case of local scorching of the food.

In order to cook food in the inner container 3, in some embodiments of the present application, the oven 100 may further include a heating assembly 8 as shown in fig. 5, where the heating assembly 8 may include a light-transmitting plate 81, a reflective cover 82 and at least one infrared light wave heating tube 83, and the inner container 3 has a heating cavity 31, and a top wall of the heating cavity 31 is opened with a first opening 311. The heating chamber 31 also has a bottom wall opposite the top wall, wherein the bottom wall can be used for placing food. The transparent plate 81 is installed at the first opening 311, and at least a portion of the transparent plate 81 covers the first opening 311. The reflective cover 82 covers the side of the transparent plate 81 away from the inner container 3. As shown in fig. 6, the heating assembly 8 is mounted on the inner container 3. As shown in fig. 7, the sectional view of fig. 6 shows that, as can be seen from fig. 7, a reflection chamber 84 is formed between the reflection cover 82 and the transparent plate 81, the reflection cover 82 has a reflection surface 821, and the reflection surface 821 faces the transparent plate 81. The infrared wave heating tube 83 is installed in the reflection chamber 84.

Thus, when the food is placed in the inner container 3 of the oven 100 and the oven 100 is operated, as shown in fig. 7, the infrared light wave heating tube 83 is heated to generate infrared light, a part of the infrared light directly irradiates the food in the inner container 3 through the light-transmitting plate 81, and another part of the infrared light irradiates the food through the light-transmitting plate 81 after being reflected by the reflection cover 82. Because of the strong permeability of infrared rays, the food can be heated inside and outside the food at the same time, and the heated food has better taste. Because the transparent plate separates the infrared wave heating tube 83 from the food, the oil stain generated when the food is cooked can directly fall into the side of the transparent plate close to the food. When the inner container 3 is cleaned, the side of the transparent plate close to the food can be directly cleaned, and because the infrared wave heating tube 83 is positioned on the side of the transparent plate far away from the food, the infrared wave heating tube 83 does not obstruct the cleaning of the inner container 3.

The above-mentioned at least one infrared light wave heating tube 83 is explained below, for example, in some embodiments of the present application, the at least one infrared light wave heating tube 83 may be an annular infrared light wave heating tube as shown in fig. 8, which is coiled in the reflection cavity 84, and since there is no heating tube in the center of the annular infrared light wave heating tube, the central heating temperature is not too high when the annular infrared light wave heating tube is heated, so that the food placed in the center of the inner container 3 in fig. 7 is not scorched.

In other embodiments of the present application, as shown in fig. 7, the at least one infrared wave heating tube 83 includes a plurality of infrared wave heating tubes 83. The infrared-wave heating tube 83 may be a straight line, the reflecting surface 821 of the reflector 82 is a first wavy surface (the bottom surface of the reflector 82 in fig. 7), and a reflector cavity 841 is formed between a convex portion (wave crest) of the first wavy surface and the transparent plate 81. The plurality of reflector cavities 841 are sequentially communicated to form a reflector cavity. At this time, one of the infrared wave heating tubes 83 is disposed in one of the reflector sub-chambers 841.

In this case, as shown in fig. 7, since the infrared light generated when the infrared light wave heating pipe 83 is heated is diffused all around, the convex portion in the first wavy surface may reflect a part of the infrared light toward the side of the light transmitting plate 81. In this way, the infrared light generated by the infrared wave heating pipe 83 can be utilized to the maximum. Moreover, since one infrared optical wave heating tube 83 is located in one reflection sub-cavity 841, infrared light rays between the infrared optical wave heating tubes 83 cannot influence each other, and the service life of the infrared optical wave heating tube 83 is prolonged.

The reflective cover 82 is illustrated below, for example, in some embodiments of the present application, as shown in fig. 9, the reflective cover 82 has a non-reflective surface 822, and the non-reflective surface 822 is disposed opposite to the reflective surface 821. The shape of the non-reflective surface 822 is not limited in this application, and the non-reflective surface 822 may be a second wavy surface that matches the shape of the first wavy surface. In this way, the thickness between the first wavy surface and the second wavy surface is the same at the position of the reflection cover 82, in this case, the reflection cover 82 can be directly punched when being processed, so that the occupied space of the reflection cover 82 is saved, and the processing cost of the reflection cover 82 is saved.

In order to prevent the light-transmitting plate 81 from falling off, in some embodiments of the present application, the oven 100 may further include a plurality of supporting members 85 as shown in fig. 10, the supporting members 85 are disposed along a circumference of the light-transmitting plate 81, a portion of the supporting members 85 is connected to the inner container 3, and another portion of the supporting members abuts against a side of the light-transmitting plate 81 away from the infrared light wave heating tube 83 (not shown in fig. 10).

In this case, after the supporting members 85 provided around the transparent plate 81 are fixed to the inner container 3, a certain support can be formed on the transparent plate 81 above the supporting members 85, and the supporting members 85 can be uniformly arranged, so that the supporting force of the supporting members 85 on the transparent plate 81 can be uniformly distributed on each supporting member 85. And contributes to the stability of the light-transmitting panel 81.

After the infrared optical wave heating tube 83 is heated, the generated high temperature will affect the transparent plate 81 to a certain extent, and the transparent plate 81 expands with heat and contracts with cold, which is easy to damage. Therefore, in some embodiments of the present application, the oven 100 may further include a plurality of U-shaped metal members 86 as shown in fig. 10, the U-shaped metal members 86 have U-shaped grooves, the plurality of U-shaped metal members 86 are disposed at intervals along the circumference of the light-transmitting plate 81, and the edge of the light-transmitting plate 81 is clamped in the U-shaped grooves.

Therefore, the U-shaped metal pieces 86 can be uniformly arranged on the periphery of the transparent plate 81, so that the thermal deformation of the transparent plate 81 is limited to a certain extent, the deformation amplitude of the transparent plate 81 can be effectively reduced, and the damage probability of the transparent plate 81 is reduced.

Since the surface temperature of the reflective cover 82 increases when the infrared heating tube 83 is heated, in order to prevent the reflective cover 82 from being too hot and burning the user, in some embodiments of the present application, the oven 100 may further include a heat shield 87 as shown in fig. 11, wherein the heat shield 87 is disposed on a side of the reflective cover 82 away from the infrared heating tube 83, and the heat shield 87 is connected to the inner container 3.

In this case, since there is a certain space between the heat shield 87 and the reflection cover 82, the temperature of the heat shield 87 is much lower than that of the reflection cover 82, so that the possibility of scalding the user can be reduced. The heat shield 87 may be completely covered on the outer surface of the reflection cover 82 and connected to the inner container 3 such that the heat shield 87 is located between the inner container 3 and the outer case 2. Accordingly, heat shield 87 is not visible on the exterior surface of enclosure 2, and does not affect the exterior aesthetics of oven 100.

In order to reduce the loss of heat in the reflective cavity 84, in some embodiments of the present application, the oven 100 may further include a heat insulation cotton 88 as shown in fig. 11, the heat insulation cotton 88 is disposed around the heat insulation cover 87, and is located on one side of the heat insulation cover 87 close to the light-transmitting plate 81, the heat insulation cotton 88 is sleeved on the outer ring of the reflective cover 82, and the heat insulation cotton 88 abuts against one side of the light-transmitting plate 81 close to the heat insulation cover 87.

In this case, first, the heat insulating cotton 88 can make the contact position between the heat insulating cover 87 and the transparent plate 81 more airtight, and thus can reduce heat loss between the heat insulating cover 87 and the transparent plate 81. Next, since the heat shield 87 is made of a hard material resistant to high temperature, the transparent plate 81 is made of one of transparent quartz glass and transparent glass ceramics. Therefore, if the heat insulating cotton 88 is not provided, the contact position between the light-transmitting plate 81 and the heat insulating cover 87 is easily damaged. In some embodiments of the present application, the toaster 100 may further comprise a ring-shaped member positioned within the heat shield 87 for abutting against the heat insulating wool 88.

Because the temperature generated by the infrared optical wave heating tube 83 is high, in order to prevent the infrared optical wave heating tube 83 from scorching food, in some embodiments of the present application, a first through hole 823 may be further disposed on the reflection cover 82 in fig. 9, and a second through hole 871 may be disposed on the heat insulation cover 87 in fig. 12 to communicate with the first through hole 823. The oven 100 may further include a first vent 89 as shown in fig. 13, one end of the first vent 89 is connected to the side of the heat shield 87 away from the reflective cover 82, and the first vent 89 is in communication with the second vent 871. One end of the second ventilation tube 90 is connected to the reflective cover 82, the other end is located on one side of the reflective cover 82 away from the transparent plate 81, and the second ventilation tube 90 is communicated with the reflective cavity 84.

In this case, as shown in fig. 13, the first ventilation pipe 89 may be installed at the center of the heat shield 87, and since the first ventilation pipe 89 communicates with the first through hole 823 of the reflection cover 82, the first ventilation pipe 89 communicates with the reflection chamber, so that the heat generated by the infrared wave heating pipe 83 in the reflection chamber 84 can be exhausted along with the first ventilation pipe 89. A plurality of second ventilation pipes 90 may be provided around the first ventilation pipe 89, and since the second ventilation pipes 90 also communicate with the reflection chamber 84, a part of the heat in the reflection chamber 84 may be discharged through the second ventilation pipes 90. So that the temperature in the reflective cavity 84 is not too high to affect cooking.

In order to better discharge a portion of heat in the reflective cavity 84, in some embodiments of the present application, the oven 100 further includes an air duct 91 and a fan 92 as shown in fig. 14, wherein the air duct 91 is disposed outside the inner container 3 and connected to an outer wall of the inner container 3, the first vent pipe 89 and the second vent pipe 90 are communicated with the air duct 91, and the fan 92 is communicated with the air duct 91.

As shown in fig. 14, since the first and second ventilation pipes 89 and 90 are communicated with the air duct 91, when the blower 92 is operated, a certain negative pressure is formed in the air duct 91, and heat in the reflection chamber 84 communicated with the first and second ventilation pipes 89 and 90 is sucked into the air duct 91 and discharged from the air duct 91. And the blower 92 may be set to a plurality of gears, so that the blower 92 is in different gears according to the detected temperature in the oven 100. In addition, the blower 92 may accelerate the flow of gas so that the temperature within the reflective cavity 84 may be rapidly reduced, helping to regulate the temperature within the oven 100.

In some embodiments of the present application, the oven 100 may further include a plurality of springs 93 as shown in fig. 14, wherein one spring 93 is sleeved outside one second vent pipe 90. One end of the spring 93 abuts against the outer wall of the air duct 91, and the other end of the spring 93 abuts against the side of the heat shield 87 away from the light-transmitting plate 81.

In this case, as shown in fig. 14, the spring 93 is in a compressed state, and the spring 93 exerts a downward force on the heat insulating cover 87, so that the heat insulating cover 87 exerts a force on the heat insulating cotton 88 therebelow, and the heat insulating cotton 88 abuts against the light-transmitting plate 81, and therefore, when the spring 93 is in a compressed state, the gap between the heat insulating cover 87 and the light-transmitting plate 81 is sealed. If the oven 100 fails, the temperature in the reflecting cavity 84 is too high, and due to the thermal expansion principle, the hot air flow in the reflecting cavity 84 pushes the heat shield 87 and the transparent plate 81 open, so that a certain gap is exposed, the hot air flow can flow out from the gap, and the cracking of the reflecting cavity 84 due to too much hot air flow is avoided.

In some embodiments of the present disclosure, as shown in fig. 15, a second opening 312 may be further opened on a side wall of the heating cavity 31 of the inner container 3, and the second opening 312 may be located at a rear side of the inner container 3. The oven 100 may further include a shield 94 and a radiant heating pipe 95, wherein the shield 94 is installed at the second opening 312 and connected to the inner container 3. The radiant-heating pipe 95 is mounted on the side of the protective hood 94 remote from the heating chamber 31, and a rear cover 96 can also be provided on the outside of the radiant-heating pipe 95.

Thus, when the infrared heating tube 83 is heated, the radiant heating tube 95 can be simultaneously started to supplement and heat the food in the inner container 3, and at this time, the rotary plate 7 for placing the food can be arranged in the heating chamber 31, and in this case, the rotation of the rotary plate 7 can make the inner and outer baking of the food more uniform.

To accomplish heating of the ir-wave heating pipe 83 and the radiant heating pipe 95, in some embodiments of the present application, the oven 100 may further include two wire holders (not shown in the present application), wherein one wire holder is connected to the ir-wave heating pipe 83, the other wire holder is connected to the radiant heating pipe 95, and both wire holders are electrically connected to a power source. In this way, the infrared wave heating pipe 83 and the radiant heating pipe 95 can be powered through the wire holder, thereby completing the cooking of the food.
