[0026] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0027] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0029] The embodiment of the utility model provides an oven with infrared heating tubes, such as Figure 1-3 As shown, it includes an outer shell 100, an inner shell 200, a heat conducting plate 300 and an infrared heating device 400. The infrared heating device 400 includes an infrared heating tube 410. The infrared heating tube 410 can emit infrared radiation when working to heat food. The inner shell 200 is provided with a heating cavity 201 for placing food to be baked. The food is placed in the heating cavity 201 to bake the food by the heat emitted by the infrared heating device 400. The inner shell 200 is located on the inner side of the outer shell 100, and a certain distance is spaced between the bottom of the inner shell 200 and the bottom of the outer shell 100 to form a receiving space 101 between the bottom of the inner shell 200 and the bottom of the outer shell 100 for accommodating other objects. The bottom of the inner shell 200 is provided with a through opening, and the heat conducting plate 300 is fixed to the inner side of the inner shell 200 and covers the opening to prevent food from falling from the opening, and food can be placed on the heat conducting plate 300, and the heat conducting plate 300 can be made of microcrystalline glass or other materials. The infrared heating device 400 is arranged in the accommodating space 101, and the opening corresponds to the infrared heating device 400. The heat radiation of the infrared heating device 400 is mainly emitted to the heat conducting plate 300 through the opening. The existence of the opening can reduce the blocking of heat radiation and improve the heat conduction efficiency.

[0030] The infrared heating device 400 is fixed at the bottom of the inner shell 200. The infrared heating device 400 is not clamped and fixed by the outer shell 100 and the inner shell 200. The infrared heating device 400 is spaced a preset distance from the bottom of the outer shell 100 to increase the distance between the infrared heating device 400 and objects such as cabinets where the entire oven is placed, reduce the impact of the heat radiation of the infrared heating device 400 on these objects where the oven is placed, and reduce the risk of damage to the objects where the oven is placed.

[0031] In this embodiment, the surface of the outer shell 100 may also be provided with a slot communicating with the heating cavity 201, and the user can put food into the heating cavity 201 or take food out of the heating cavity 201 through the slot. The outer shell 100 is provided with an openable door 110 to open or close the slot. In order to facilitate observation of the internal structure, Figure 2 and Figure 3 The box door 110 is removed.

[0032] In some embodiments, a plurality of brackets 500 are provided in the accommodating space 101, the brackets 500 are fixed to the bottom of the inner shell 200, and the brackets 500 are connected to the infrared heating device 400, so that the infrared heating device 400 can be installed and fixed by the brackets 500, thereby simplifying its installation structure.

[0033] Further, such as Figure 3 and Figure 4 As shown, the bracket 500 includes a first fixing plate 510, a connecting plate 530 and a second fixing plate 520. The first fixing plate 510 is fixed to the bottom of the inner housing 200, the connecting plate 530 extends in the vertical direction, the upper end and the lower end of the connecting plate 530 are respectively connected to the first fixing plate 510 and the second fixing plate 520, and the second fixing plate 520 is fixedly connected to the infrared heating device 400. The connecting plate 530 extends in the vertical direction, so that the second fixing plate 520 is at a relatively low height, and the second fixing plate 520 can be in a state of supporting the infrared heating device 400 to improve the stability of the installation of the infrared heating device 400.

[0034] The second fixing plate 520 can be connected to the bottom of the infrared heating device 400, and the bottom of the infrared heating device 400 is not blocked to provide a larger installation space. Any two or all of the first fixing plate 510, the connecting plate 530 and the second fixing plate 520 are integrally connected, or the first fixing plate 510, the connecting plate 530 and the second fixing plate 520 are separately arranged and fixed together.

[0035] Furthermore, a plurality of brackets 500 are provided and arranged around the infrared heating device 400 to share the force of a single bracket 500 and strengthen the fixation of the infrared heating device 400 so that it is stably fixed to the bottom of the inner shell 200 .

[0036] In some embodiments, the infrared heating device 400 extends into the opening at the bottom of the inner housing 200 and abuts against the heat conducting plate 300. On the one hand, the side wall of the opening can limit the infrared heating device 400, restricting the infrared heating device 400 from moving in the lateral direction to keep it stable; on the other hand, the infrared heating device 400 abuts against the heat conducting plate 300, which can minimize the distance between the infrared heating tube 410 and the heat conducting plate 300, thereby enhancing heat radiation and enhancing the baking effect on food.

[0037] In some embodiments, a convex ring 210 is arranged around the heat conducting plate 300 on the inner bottom wall of the heating chamber 201, that is, on the bottom wall on the inner side of the inner shell 200. The convex ring 210 surrounds the heat conducting plate 300 for a week to limit the heat conducting plate 300 and restrict the lateral movement of the heat conducting plate 300 on the inner bottom wall of the heating chamber 201 to keep it stable.

[0038] In some embodiments, Figure 3 and Figure 5 As shown, the infrared heating device 400 also includes a baking tray 420, and the infrared heating tube 410 is fixed in the baking tray 420. The baking tray 420 can block the heat radiation of the infrared heating tube 410 from being emitted downward to further reduce the impact of heat radiation on objects placed in the oven and reduce the risk of damage to the objects placed in the oven.

[0039] like Figure 5 As shown, a fixing groove may be provided on the top of the baking tray 420, and the external heating tube 410 is provided in the fixing groove to mainly radiate heat upward.

[0040] Furthermore, a temperature control switch 430 is fixed on the baking tray 420, and the temperature control switch 430 monitors the temperature of the external heating tube 410 in real time. When the temperature is too high, the temperature control switch 430 can be disconnected to play a role in overheating protection.

[0041] In some embodiments, the infrared heating tube 410 is spirally wound in the baking pan 420 , and the infrared heating tube 410 can radiate heat evenly.

[0042] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
