Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the utility model provides a food baking machine and a pizza machine.

[0005] The utility model is realized by the following technical solutions:

[0006] The utility model provides a food baking machine, comprising:

[0007] A machine body, wherein the machine body has a baking cavity;

[0008] A lower heating element, which is arranged on the machine body and located below the baking cavity, and is used to heat the heat conducting plate;

[0009] An infrared heating element is arranged on the machine body and located above the baking cavity, and is used to heat food on the heat-conducting plate.

[0010] The food baking machine of the utility model has an infrared heating element arranged above the baking cavity. The infrared heating element heats faster and has stronger penetrating power. The infrared heating element can be used to quickly heat the baking cavity and the heat conducting plate, thereby quickly heating the food, shortening the baking time and improving the baking efficiency.

[0011] In one embodiment, there are multiple infrared heating elements, each of which extends along the depth direction of the baking cavity, and the multiple infrared heating elements are arranged in sequence along the width direction of the baking cavity;

[0012] Alternatively, each infrared heating element extends along the width direction of the baking cavity, and a plurality of infrared heating elements are arranged in sequence along the depth direction of the baking cavity. In this way, the baking cavity and food can be heated quickly and evenly with the help of a plurality of infrared heating elements, with higher heating efficiency and more even heating.

[0013] In one embodiment, the food baking machine further comprises:

[0014] A controller is provided, wherein the controller is electrically connected to the lower heating element and the infrared heating element, and the controller is used to control the lower heating element and the plurality of infrared heating elements to operate independently, that is, the lower heating element and the plurality of infrared heating elements all operate independently, so as to set different heating times according to different foods, and to be more flexible in use.

[0015] In one embodiment, the food baking machine further comprises a protective frame, the protective frame is located in the baking cavity and forms a first installation cavity with the machine body, and the first installation cavity accommodates the infrared heating element. By providing the protective frame, on the one hand, it can play a protective role to prevent users from contacting the infrared heating element and causing burns, and on the other hand, the protective frame is a hollow structure, which can allow the infrared light emitted by the infrared heating element to be efficiently radiated to the baking cavity to ensure heating efficiency.

[0016] In one embodiment, the food baking machine further comprises:

[0017] The heat-resistant glass plate is arranged in the baking cavity and forms a second installation cavity with the machine body, and the second installation cavity accommodates the lower heating element. By arranging the heat-resistant glass plate, the lower heating element is sealed in the second installation cavity by using the heat-resistant glass plate, so that the heating surface of the lower heating element becomes a plane (that is, the top surface of the heat-resistant glass plate), which can prevent food residues or juice from falling onto the lower heating element, making it easier to clean. At the same time, the heat-resistant glass plate is made of transparent material, which can efficiently radiate the heat of the lower heating element to the baking cavity, ensuring heating efficiency.

[0018] In one embodiment, the food baking machine further comprises:

[0019] A heat-conducting plate is slidably inserted in the baking cavity. The heat-conducting plate slides and can switch between being located in the baking cavity and being located outside the baking cavity. The heat-conducting plate is used for supporting food.

[0020] In one embodiment, both sides of the baking cavity in the width direction have a guide portion and a positioning portion, and the height of the positioning portion is lower than the height of the guide portion;

[0021] The heat-conducting plate has a first state in which it is in contact with the top surface of the heat-resistant glass plate and a second state in which it is separated from the heat-resistant glass plate;

[0022] When the heat conducting plate is in the first state, the heat conducting plate and the positioning portion cooperate to achieve positioning of the heat conducting plate, ensuring that the heat conducting plate and the top surface of the heat-resistant glass plate are in contact with each other, thereby improving heat conduction efficiency and thus improving heating efficiency;

[0023] When the heat conducting plate is in the second state, the heat conducting plate and the guide portion cooperate and can slide along the guide portion, so that the heat conducting plate will not contact the heat-resistant glass plate when sliding along the guide portion, thereby avoiding friction between the heat conducting plate and the heat-resistant glass plate to damage the heat conducting plate or the heat-resistant glass plate. At the same time, the heat conducting plate can slide smoothly, making it convenient to push and pull the heat conducting plate.

[0024] In one embodiment, the food baking machine further comprises:

[0025] A support frame, wherein a connecting portion is provided on the support frame, and the support frame supports the heat conducting plate;

[0027] When the heat conducting plate is in the second state, the connecting part cooperates with the guiding part and can slide along the guiding part. That is, the heat conducting plate cooperates with the guiding part and the positioning part indirectly through the supporting frame, so that the heat conducting plate can be exempted from structural changes, which is conducive to reducing the processing difficulty of the heat conducting plate, and further can reduce the cost of the food baking machine. At the same time, because the supporting frame is a hollow structure, the heat emitted by the lower heating element can be efficiently radiated to the heat conducting plate through the gap on the supporting frame, thereby ensuring the heating efficiency.

[0028] In one embodiment, the guide portion has a guide groove, and the guide groove extends along the depth direction of the baking cavity;

[0029] The positioning part has a positioning groove, and the positioning groove is connected to the guide groove. Since the guide part cooperates with the heat conducting plate in the form of a groove, it can play a role of limiting and guiding, ensuring that the heat conducting plate slides smoothly while preventing the heat conducting plate from moving a large distance along the height direction of the baking chamber. The guide part of the groove structure is simple and practical, which is convenient for processing and can also reduce costs. Similarly, since the positioning part cooperates with the heat conducting plate in the form of a groove, it can realize reliable positioning of the heat conducting plate. At the same time, the positioning part of the groove structure is simple and practical, which is convenient for processing and can also reduce costs.

[0030] The utility model also provides a pizza machine, comprising the above-mentioned food baking machine.

[0031] The pizza machine of the utility model, due to adopting the above-mentioned food baking machine, can also utilize the infrared heating element to realize rapid heating of the baking cavity and the heat conducting plate, thereby rapidly heating the food, realizing shortening the baking time and improving the baking efficiency.

[0032] Beneficial effects of the utility model:

[0033] The food baking machine of the present invention can heat the baking cavity simultaneously with the help of the lower heating element and the infrared heating element to ensure heating efficiency and realize uniform heating. At the same time, since the infrared heating element is arranged above the baking cavity, the infrared heating element heats faster and has stronger penetration.
