Claims

[Scope of utility model registration request]

(1) In a high-frequency heating device equipped with a high-frequency oscillator and a heating chamber that is equipped with the high-frequency oscillator and accommodates an object to be heated, the heating chamber is provided with a high-frequency oscillator that stirs the microwaves oscillated from the high-frequency oscillator. A starra fan of a high-frequency heating device is characterized in that it is equipped with a blade portion that bends along an axial direction due to the influence of temperature changes.

(2) The diameter of the blade of the Stara fan is 11 pieces xn
(where λ is the wavelength of the high frequency in free space, and n is a positive integer).

(3) The length of the blade of the star fan blade is x/
4.times.4.times.n. A starra fan for a high frequency heating device according to claim 1, which is a utility model.

(4) The wind protection part of the blade part of the Stara fan is a-b.
Request for registration of a utility model characterized by having a slope of /c (a: rising dimension on the outer peripheral end side of the wind shielding part, b: rising dimension on the inner peripheral end side of the wind shielding part, C: length dimension of the wind shielding part) Scope: Stara fan for high-frequency heating equipment described in item 1.
