AI Technical Summary
The heating system of a traditional air fryer is on the top, resulting in poor heat transfer at the bottom, easy to clamp and poor frying and grilling, and it is impossible to ensure that both sides of the food are heated evenly.
An air fryer is designed, using a heat transfer base plate located under the frying barrel, equipped with a PTC heater, and combined with self-temperature limiting technology, the heating power is automatically adjusted to achieve uniform heating of the bottom of the pot.
Through the self-limiting temperature technology of the PTC heater, the food is heated evenly on both sides, avoiding the phenomenon of clamping and improving the frying and grilling effect.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of air fryers. Background Art
[0002] The heating system of traditional air fryers is at the top, and uses the air convection method to conduct heat to the whole fryer. The bottom area of the fryer is blocked by food, and the ventilation and heat conduction are limited, resulting in poor heat transfer effect. It is easy to have undercooked food, poor grilling effect, and unable to ensure uniform grilling on both sides of the grilled food. Summary of the Utility Model
[0003] To solve the above problems, the technical solution provides an air fryer.
[0004] To achieve the above object, the technical solution is as follows:
[0005] An air fryer includes a pot body, the pot body is provided with a frying barrel, the pot body is provided with a heating component above the frying barrel, and a heat transfer bottom plate is provided below the frying barrel, and the heat transfer bottom plate is provided with a PTC heater.
[0006] In some embodiments, the heating component includes an electric heating tube close to the frying barrel, and further includes a wind wheel above the electric heating tube and a motor for driving the wind wheel.
[0007] In some embodiments, the heat transfer bottom plate is provided with screw holes for fixing the PTC heater.
[0008] In some embodiments, a temperature control knob for controlling the heating power of the heating component is provided above the pot body, and a timing knob is also provided.
[0009] The beneficial effect of this application is:
[0010] This application provides a new heating structure, specifically including a PTC heater. The PTC structure is simple to install and convenient to operate; at the same time, according to the self-limiting temperature technology of the PTC heater, when the bottom temperature rises, the power is automatically reduced, and when the bottom temperature drops, the PTC heater is started, which can continuously supplement heat to the bottom of the pot, so as to achieve the best grilling effect on both sides of the food. Description of the Drawings
[0011] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model, the following will briefly introduce the drawings required for description in the embodiments.
[0012] Figure 1 It is a schematic structural diagram of an embodiment of the present utility model;
[0013] Figure 2 It is a cross-sectional schematic diagram of an embodiment of the present utility model. Detailed implementation mode
[0014] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0015] Please refer to Figure 1-2 As shown, an air fryer includes a pot body. The pot body is provided with a frying barrel 1. Above the frying barrel 1, the pot body is provided with a heating assembly, and below the frying barrel 1, there is a heat transfer bottom plate 2. The heat transfer bottom plate 2 is provided with a PTC heater 3.
[0016] The heating assembly is used to heat the upper surface of the food above the frying barrel, while the PTC heater can be used to heat the bottom of the food below. At the same time, according to the "self-limiting temperature technology" of the PTC heater, when the bottom temperature rises, the power is automatically reduced, and when the bottom temperature drops, the PTC heater is started, which can continuously supplement heat to the bottom of the pot, so as to achieve the best double-sided frying effect of the food.
[0017] In this embodiment, the heating assembly includes an electric heating tube 4 close to the frying barrel 1, and further includes a wind wheel 5 above the electric heating tube 4 and a motor 6 driving the wind wheel 5. The motor drives the wind wheel, so that the wind wheel uses wind power to bring the heat generated by the electric heating tube to the food.
[0018] In this embodiment, the heat transfer bottom plate 2 is provided with screw holes 7 for fixing the PTC heater 3, which is convenient for assembly and disassembly and replacement.
[0019] In this embodiment, above the pot body, there is a temperature control knob 8 for controlling the heating power of the heating assembly, and a timing knob 9 is also provided.
[0020] The above is only the preferred embodiment of the present application, and is not used to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to the present application are all within the protection scope of the present application.
