In response to the selection operation of the third mode by the user through the operation component, the heating component 20 is controlled to heat the food material in the oven cavity 11, and the power is cut off at preset time intervals to stop heating or powered on to continue heating, so as to reduce the water content of the food material.

The toaster adopting the structure provides three modes, wherein the first power is relatively low heating power, and food baked by the toaster belongs to conventional mouthfeel in the first mode; the second power is relatively high heating power, and in the second mode, the heating temperature of the heating part 20 is high, so that the surface of the food material can be quickly scorched, the moisture in the food material can be locked, and the baked food is scorched outside and tender inside; under the third mode, the heating part 20 carries out discontinuous heating to eating material 80, and heating part 20 stops the heating in-process, utilizes in the furnace chamber 11 residual temperature to toast eating material 80, can increase the moisture loss of eating material 80, reduces and eats material moisture content, and the food taste of toasting the completion is crisp, and it is even to roast the look, and total power consumption is lower moreover, is of value to practicing thrift the electric energy, can reduce the energy consumption. Thus, the toaster can toast a variety of toasted foods.

In some embodiments, the controller 30 may include a timing unit and a control unit, when the user selects the third mode, the control unit controls the heating component 20 to be powered on, and at the same time, the timing unit starts timing and sends a signal to the control unit according to the preset time interval, so that the control unit controls the heating component to be powered off or powered on according to the preset time interval, so as to achieve the purpose of intermittent heating. For example, the timing unit may be configured to start timing when the heating member 20 is powered on to start heating, and when the heating member 20 continues to heat for a first preset time, the timing unit sends a first signal to the control unit, and the control unit controls the heating member 20 to be powered off to stop heating. When the heating part 20 stops heating and continues for a second preset time, the timing unit sends a second signal to the control unit, and the control unit controls the heating part 20 to be powered on to continue heating, and the process is circulated until the food material 80 is baked, so that the discontinuous heating is realized.

In some embodiments, the toaster may further include a power supply module 40, wherein the power supply module 40 is respectively connected to the power input, the controller 30 and the heating member 20, and independently supplies power to the controller 30 and the heating member 20, respectively, such that in the third mode, when the control unit controls the heating member 20 to be powered off according to the preset time interval, the controller 30 is not powered off, and the timing unit can continue to time and send a signal to the control unit according to the preset time interval, so that the control unit can control the heating member 20 to be powered on again to continue heating.

As shown in fig. 2 and 3, in particular, a grill 13 for supporting food 80 may be disposed in the cavity 11, the grill 13 may be configured to move in a vertical direction, a magnetic member is disposed on the grill 13, an electromagnet 14 and a first switch 61 are disposed at the bottom of the cavity 11, the power module 40 is connected to the power input 50 through the first switch 61, and the control unit is connected to the electromagnet 14.
