Problems solved by technology

The above-mentioned food processing machine includes electric appliances for baking such as air fryer, electric oven, barbecue oven and food oven. Now there is an air fryer that heats the food in the cooking cavity through a hot air device arranged in the housing. Air fryer The hot air device of the pot includes fans and heating elements, but the control of the temperature range in the cooking cavity by the air fryer is still completed by controlling the on and off of the heating tube. In this control method, the frequent on and off actions of the heating tube will cause cooking The temperature fluctuation range in the cavity is large, the temperature control in the cooking cavity is not accurate, and the fans in the heating device are all running at the highest speed of full power. The high speed of the fan makes the heat loss of the hot air flow large, and will cause Food loses more moisture, which affects the cooking quality and taste of food cooking

Embodiment 1

[0040] Such as figure 1, the present embodiment provides a household electric oven, comprising an upper casing 1, a lower casing 2 and a fryer 7 for cooking food, the lower casing 2 is provided with a fryer, and the fryer 3 is detachably set In the cavity, the upper shell 1 is provided with a cover plate 11, the upper surface of the cover plate 11 and the inner wall of the upper shell 1 form an accommodating cavity 12, and the lower surface of the cover plate 11 and the fryer 3 form a In the cooking cavity, the upper housing 1 is provided with a hot air device, a control device, an air duct, and a temperature sensor 6. The hot air device includes a heating pipe 41 and a fan, and the fan includes a shaded pole motor 43 and fan blades 42. The shaded pole motor 43 drives the fan blade 42 to rotate. The control device and the motor are installed in the accommodating cavity 12. The control device includes an operation panel on the outer surface of the upper casing. The user selects...

Embodiment 2

[0065] Such as Figure 8 The difference between the method for controlling grilled food provided in this embodiment and that in Embodiment 1 is that it includes the steps of judging the speed of the fan:

[0066] Before the fan speed changes from An to An-1, first judge whether the speed An is the lowest speed. If the fan speed An is the lowest speed, it will always run at the An speed until the end of cooking; if the fan speed An is not the lowest speed, the fan will Will run at An-1 speed. By setting this step, the abnormal operation of the fan caused by the low fan speed can be prevented, and the fan can be prevented from working outside the working range, which affects the service life.

[0067] The remaining structural features of the electric oven described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0069] The difference between this embodiment and the first embodiment lies in that the driving circuit for controlling the speed of the fan is different.

[0070] In the fan drive circuit of this embodiment, no silicon controlled rectifier and related circuits are provided, but a parallel circuit of relays is used to control the speed of the fan. Such as Figure 9 , in this embodiment, the fan driving circuit includes a relay K and a plurality of resistors R, wherein the relay K1 is connected in series with the resistor R1, the relay K2 is connected in series with the resistor R2, the relay K3 is connected in series with the resistor R3, and then the series circuit of the above relays The two ends of the fan are connected in parallel and then connected in series with the circuit where the fan is located to form a fan drive circuit. The single-chip microcomputer sends a conduction signal to the relay circuit to control the conduction or disconnection of each relay, so that th...

Abstract

The invention relates to the field of kitchen appliances, in particular to a frying and roasting method and a control device of a food processor for frying and roasting foods by hot air. The frying and roasting method and the control device have the advantages that a fan can run at corresponding rotating speeds according to selected tap positions and working states of a heating tube, and circulating speed of air in the food processor is regulated through the rotating speeds of the fan, so that cooking temperatures can be regulated; the foods in a cooking chamber are heated through circular hot air flow, more uniform heating is achieved, and different tap positions can be selected to enable the fan to run at different speeds according to different cooking foods, so that food cooking effects are improved; the hot air flow is mitigated to reduce impact of heat on components of the food processors, and accordingly safety and reliability are achieved.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a frying method and a control device of a food processor using hot air to fry food. Background technique [0002] At present, there is a food processor that includes a cooking cavity and a heating tube. The heating tube is used as a heat source to cook the food in the cooking cavity, and the food processor controls the temperature in the cooking cavity by controlling the on-off of the heating tube. , there is a problem of inaccurate temperature control. The above-mentioned food processing machine includes electric appliances for baking such as air fryer, electric oven, barbecue oven and food oven. Now there is an air fryer that heats the food in the cooking cavity through a hot air device arranged in the housing. Air fryer The hot air device of the pot includes fans and heating elements, but the control of the temperature range in the cooking cavity by the air fryer is still co...
