The present invention provides a cooking cavity for a microwave oven.

In an embodiment of the present invention, refer to fig. 1, 2, 3 and 4, wherein fig. 1 illustrates an exploded structure diagram of a cooking cavity in an exploded view; fig. 2 shows a schematic perspective view of a cooking chamber from a top view; fig. 3 shows a schematic view of the top wall in the cooking chamber; fig. 4 shows a schematic view of a convection net in a cooking cavity.

The cooking cavity for the microwave oven mainly comprises an upper part and a lower part of a top wall structure 1 and a bottom cavity structure 2, provides a cooking cavity for the multifunctional microwave oven to realize a basic microwave heating function, and simultaneously provides support for the microwave oven to realize an oven and an air frying function. Wherein the top wall structure 1 comprises a top wall 11 and in the plane of the top wall a top wall opening 13 is provided for accommodating a convection net 12. The convection net 12 is composed of a front vertical wall 21, a rear vertical wall 22, and a surrounding wall 23 having a substantially regular "U" shape. When the cooking cavity is assembled, the top wall structure 1 covers the bottom cavity structure 2 in a fastening manner, and the combined inner space of the top wall structure and the bottom cavity structure together form the cooking cavity for the microwave oven.

Specifically, as shown in fig. 1 and 2, when the components in the cooking chamber are assembled, the convection net 12 is received in the top wall opening 13 such that the convection net 12 is connected with the top wall opening 13 to form a planar unitary structure. The top wall 11 is disposed on the bottom cavity structure 2 in a covering manner, and left and right side edges of a lower surface of the top wall 11 are respectively connected with top edges of left and right side vertical walls of the surrounding wall 23, and the top wall 11 and the surrounding wall 23 form a substantially rectangular ring structure together in a front view. The front standing wall 21 is provided on the front side of the surrounding wall 23 and is connected to the front side of the surrounding wall 23 by bringing the inner surface of the front standing wall 21 into contact with the front side of the surrounding wall 23, and the rear standing wall 22 is provided on the rear side of the surrounding wall 23 and is connected to the rear side of the surrounding wall 23 by bringing the inner surface of the rear standing wall 22 into contact with the rear side. After the front standing wall 21 and the rear standing wall 22 are respectively connected to the front side and the rear side of the surrounding wall 23, the top wall 11 and the surrounding wall 23 together form a substantially rectangular ring structure, which is sandwiched between the front standing wall 21 and the rear standing wall 22. It should be noted that the concepts of up, down, left and right in the present and following embodiments are based on the right state of the microwave oven as a reference.

Further, the inner surface of the surrounding wall 23, the inner side surface of the top wall 11, the rear standing wall 22, and the inner surface of the front standing wall 21 are coated with an easy-to-clean coating. In order to provide the air-frying and oven functions to the microwave oven, it is necessary to additionally provide a heating tube for the microwave oven to provide a heat source for heating air and heat radiation. Therefore, the cooking cavity of the present invention is further provided with a heating tube fixing base 12b for fixing the heating tube at the convection net 12 to support the heating tube upwardly assembled to the convection net 12 from the lower side of the convection net 12. Because the heating tube can emit a large amount of heat in a heat radiation mode, if the inner wall of the cooking cavity of the microwave oven is sprayed with the coating which is easy to clean or not to stick to, the coating is easily burnt by the heat of the heating tube. Accordingly, the present invention employs a method that does not spray a coating on the convection net 12, and the high heat area above the heating tube does not conflict with the coating. Meanwhile, in order to adapt to the circular heating tube external structure, the top wall opening 13 is designed to be in a ring shape, and the convection net 12 accommodated by the ring-shaped top wall opening 13 is correspondingly arranged to be in a plane circular shape. Preferably, in order to realize various cooking modes and effectively monitor cooking parameters of the microwave oven, a through sensor positioning hole 15 is further provided on the top wall 11 for adapting the sensor to monitor cooking data in the cooking cavity.

With further reference to fig. 5, fig. 5 is a schematic perspective view illustrating the door of the microwave oven according to the present invention when opened. When the heating tube is fixed below the convection net 12 through the heating tube fixing seat 12b, the surface area of the convection net 12 is larger than or at least equal to the plane area covered by the heating tube. In other words, the projected area of the heat pipe convection net 12 in the direction perpendicular to the plane of the top wall structure 1 completely covers the projected area of the heat pipes in the direction perpendicular to the plane of the top wall structure 1. Based on the area size relationship between the heating tube and the convection net 12, the convection net 12 is arranged in the top wall 11, and the heating tube with a surface area slightly smaller than or at most equal to that of the convection net 12 is arranged under the convection net 12, so that the area of the opening 13 of the top wall is free from coating spraying, the direct thermal radiation of the heating tube on the coating is avoided from being roasted, the interior of the cooking cavity is easy to clean, and the high-temperature heat of the heating tube is ensured not to damage the easy-to-clean coating.

Preferably, for making the culinary art chamber material select more nimble, the connection of each structure all adopts the riveted mode to connect in the culinary art chamber to the restriction of welding process to the culinary art chamber material of selecting has been avoided. Therefore, the surrounding wall 23, the top wall 11, the rear vertical wall 22 and the front vertical wall 21 can be made of materials (such as aluminum plate) with relatively high microwave energy efficiency, so that the cooking efficiency of the microwave function is ensured while the whole structure is not influenced. In the preferred embodiment, after the spray coating of the interior surface of the cooking chamber is completed, a convection net 12 (preferably 304 stainless steel) is riveted to the top wall opening 13, again in a riveted connection.

Specifically, as shown in fig. 4, a plurality of convection net riveting holes 12a are provided at the edge of the convection net 12, and a plurality of top wall opening riveting holes 11a are correspondingly provided in the top wall 11 around the peripheral edge of the top wall opening 13. When the convection net 12 is connected with the top wall opening 13 by riveting, the plurality of convection net riveting holes 12a are overlapped with the top wall opening riveting holes 11 a. In other words, the projections of the convection net staking holes 12a in the direction perpendicular to the plane of the top wall structure 1 and the projections of the plurality of top wall open staking holes 11a in the direction perpendicular to the plane of the top wall structure 1 coincide with each other.

Furthermore, in order to realize the air frying function in the multifunctional microwave oven, the air flow is accelerated by elements such as a fan and the like, then the air flow is guided to flow through the heating pipe to be heated, and the hot air flow is utilized to carry out air cooking on the food materials. In order to allow an efficient flow of air through the convective mesh 12 during this heating process, a convective mesh 14 is provided in the convective mesh 12 that covers almost completely the entire convective mesh 12. Specifically, the convection mesh 14 is composed of a plurality of hole-like structures 14 a. Each of the hole-shaped structures 14a may be a circular through hole, a square through hole, or a honeycomb through hole.

Further, as shown in fig. 1 and 3, the microwave oven further includes a turntable 3 and a roasting pan. The turntable 3 is rotatably disposed on the bottom surface of the surrounding wall 23 and can be rotated by a rotating mechanism inside the microwave oven. In order to adapt the air-frying function and the oven function of the microwave oven in the embodiment of the utility model, a baking tray which is detachably arranged on the upper surface of the rotating disc 3 is also arranged.

Therefore, the cooking cavity for the microwave oven ensures the cooking efficiency under the air frying function and the oven function by arranging the convection net 12 below the top wall structure 1 and matching with the layout of the heating tube fixing seat 12b for hanging the heating tube.

The cooking cavity for the microwave oven is characterized in that the inner surfaces of the top wall structure 1 and the bottom cavity structure 2 are coated with the easy-to-clean coating, and the coating is prevented from being sprayed in the area where the convection net 12 for hanging the heating tube is located, so that the coating is effectively prevented from being burnt, and the daily cleaning of a user is facilitated.

The cooking cavity for the microwave oven of the present invention allows the material selection of the cooking cavity panel to be not limited by riveting the top wall 11, the front standing wall 21, the rear standing wall 22 and the surrounding wall 23 to each other, thereby achieving the cooking efficiency of the microwave function.
