Problems solved by technology

[0005] However, in the structure described in the aforementioned Patent Document 1, in order to estimate the life of the microwave oven, it is necessary to make the magnetron vibrate abnormally. There is such a bad situation as an electronic microwave oven that its lifespan is shortened and it is prone to failure

Embodiment Construction

[0021] Next, one embodiment of the present invention will be described with reference to the drawings. An electronic microwave oven (1) as a heating cooker is described in cross-section according to its schematic composition figure 1 As shown, a rectangular box-shaped casing (2) is provided, and the inside of the casing (2) is used as a heating and cooking chamber (3). The heating cooking chamber (3) is a space for accommodating objects to be heated for heating and cooking, and an oven door (4) which pivotally supports the lower side and is freely rotatable is arranged on the front opening of the heating cooking chamber. (3) The turntable (5) on which the object to be heated is placed is provided on the bottom surface.

[0022] On the side of the above-mentioned heating cooking chamber (3), a mechanical chamber (7) is set by a partition wall (6), and in this mechanical chamber (7) is provided with: a magnetron (8), as a mechanism for microwave heating; and Cooling fan (9) co...

Abstract

The invention provides a heating cooker which can predict service life thereof when a magnetron is not abnormally vibrated and informs a user the situation when the magnetron reaches set service life. The invention is characterized in that the heating cooker comprises a magnetron (8) supplying microwave to a heating room; a magnetron temperature detection mechanism (19) detecting temperature of the magnetron; a service life judging mechanism (18) judging service life of the magnetron; an informing mechanism (12) informing the service life judged by the service life judging mechanism. When thedetected temperature of the magnetron obtained by the magnetron temperature detection mechanism reaches over a predetermined temperature, the service life judging mechanism judges that the service life of the magnetron has reached, which is informed to the user by the informing mechanism.

Description

technical field [0001] The present invention relates to a heating cooker for estimating the lifetime of a magnetron without imposing a burden on the magnetron. Background technique [0002] Conventionally, it has generally been difficult for users to judge the usable period of an electronic microwave oven as a heating cooker, that is, the lifespan. As an approximate standard of life, it can be set by calculating and obtaining the efficiency half-life of the magnetron based on the average number of times of use of the electronic microwave oven per day, the use time, and the like. However, since the frequency of use differs greatly in each case, and users generally seldom remember the date of purchase, in the user's home, the reality is that the heating cooker is not aware of the end of its service life and is in an inefficient state. continue to use. [0003] On the other hand, Patent Document 1 discloses a technique of obtaining the remaining lifetime of a magnetron by com...
