Embodiment approach 1

[0044] figure 1 It is a partial cutaway side view in the state which fully closed the door 3 of the heating cooker concerning Embodiment 1 of this invention. figure 2 It is a partial cutaway side view of the heating cooker of this embodiment in the state which opened the door 3 halfway. image 3 It is a partial cutaway side view in the state which fully opened the door 3 of the heating cooker of this embodiment.

[0045] In this embodiment, the door 3 side of the main body 1 of the heating cooker, that is, Figure 1 ~ Figure 3 The left side in is the front. When facing from the front to the right side of subject 1, i.e. Figure 1 ~ Figure 3 The near front side in the middle is taken as the right side. The state in which the door 3 is completely closed is referred to as a fully closed state of the door 3 , and the state in which the door 3 is fully opened is referred to as a fully open state of the door 3 .

[0046] Such as Figure 1 ~ Figure 3 As shown, a heating chamb...

Embodiment approach 2

[0087] Embodiment 2 of the present invention will be described below. Figure 7 It is a partially cutaway side view of the heating cooker of this embodiment.

[0088] Such as Figure 7 As shown, in this embodiment, the door opening and closing mechanism 4 has the door arm 5 , the roller 6 , the spring 7 , and the support portion 8 as in the first embodiment.

[0089] However, unlike Embodiment 1, the support portion 8 is formed of a substantially U-shaped member having an inner edge and an outer edge. On the upper edge of the door arm 5, a contact portion 5a is formed so as to protrude upward. Inclined portions are formed in front and rear of the apex of the contact portion 5a. The roller 6 is attached to the support portion 8 .

[0090] The spring 7 has one end connected to the rear end of the door arm 5 and the other end connected to the main body 1 (more precisely, the rear portion of the support portion 8 fixed to the main body 1). The spring 7 is disposed behind the ...

Abstract

This heat-cooking device is equipped with a heating chamber, a door, a support part, a spring, and a door arm. The heating chamber is provided in the main body and configured so as to house an item tobe heated therein. The door is configured so as to cover the front-surface opening of a heating chamber. The support part is provided in the main body. The spring has one end which is connected to the main body. The door arm has one end that is rotatably connected to the door, and another end which is connected to the other end of the spring. The door arm is configured so as to move in unison with the door movement when the door opens or closes. The door arm contacts the support part from below in a contact section. When the door is opened to a prescribed opening angle, the contact section has an angle of tilt which tilts downward toward the front. When the door is opened to the prescribed opening angle, the spring pulls the door arm upward and rearward. This technology makes it possibleto make a door opening/closing mechanism more compact while maintaining the performance thereof.
