According to the first aspect, the cost can be reduced by configuring the pump for returning the edible oil discharged from the lower part of the oil reservoir to the oil reservoir by a manual pump. However, even when the pump bites the frying, the bite can be easily and quickly eliminated by using a manual force that can generate a drastically larger force than the electric power of the electric pump. It is possible to provide a fryer which is excellent in cost and use. In addition, a manual pump having a simpler structure than an electric pump is not only small and light, but also hard to break down, and further has the advantage that running costs are unnecessary.

According to the second aspect of the present invention, a valve is provided at a lower portion of the oil reservoir to switch between a state in which the edible oil discharged therefrom is discharged to the outside and a shut-off state in which the edible oil is not discharged. By manually connecting the return pump to the oil passage until the edible oil is supplied, the manual pump is operated by manual force even if the valve fails, such as when the valve cannot be switched from the shut-off state to the discharge state. Thus, frying dust, dust, and the like can be filtered irrespective of the valve, and use in a state where there is no disadvantage in use is possible. Further, there is no need to switch the valve every time the manual pump is operated, which is advantageous in terms of use.

According to the third aspect, the edible oil is returned from the return oil passage to the low-temperature edible oil below the plurality of heating units in the oil tank of the oil storage unit. Even if the fryer is configured to return the edible oil from the return oil passage, the high-temperature edible oil above the heating part to be fried is not lowered by the edible oil from the return oil passage. It can be fried in the temperature state.
