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] like Figure 1 ~ Figure 3 As shown, a heating chamber ...

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] like 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 con...

Abstract

The heating cooker has a heating chamber, a door, a support, a spring, and a door arm. The heating chamber is provided in the main body and is configured to house the object to be heated. The door is configured to openably and closably cover the front opening of the heating chamber. The supporting part is arranged on the main body. The spring has one end connected to the main body. The door arm has one end rotatably connected to the door and the other end connected to the other end of the spring, and is configured to move in conjunction with the operation of the door when the door is opened and closed. The door arm abuts against the support portion from below at the abutting portion. At a predetermined opening angle of the door, the contact portion has an inclination angle inclined downward with respect to the front direction. The spring is configured to pull the door arm rearward and upward at a predetermined opening angle of the door. According to this aspect, the door opening and closing mechanism can be downsized while maintaining the performance.
