The cooling fan 50 cools electrical components such as the magnetron 10.

図２は上記電子レンジの後側かつ斜め上方から見た斜視図を示し、図３は上記電子レンジのラッチ部材４０の上フック４３,下フック４５が係止部５１,５２に係止した状態の縦断面図を示している。図２,図３では、本体ケーシング１から側板(図示せず)と天板１２(図１に示す)を外した状態を示している。図２,図３おいて、図１と同一の構成部には同一参照番号を付している。   FIG. 2 is a perspective view of the microwave oven as viewed from the rear side and obliquely upward. FIG. 3 shows a state in which the upper hook 43 and the lower hook 45 of the latch member 40 of the microwave oven are locked to the locking portions 51 and 52. FIG. 2 and 3 show a state in which a side plate (not shown) and a top plate 12 (shown in FIG. 1) are removed from the main casing 1. 2 and 3, the same components as those in FIG. 1 are denoted by the same reference numerals.

図２,図３に示すように、モータ２０により駆動されるレバー部材３０のレバー先端部３１が、ラッチ部材４０の下側の下フック４５に当接している。また、モータ２０の駆動軸に羽根車２１の軸部２１ａを連結している。羽根車２１は、軸部２１ａと、軸部２１ａの外周に周方向かつ等間隔に設けられた４つの羽根部２１ｂを有する。上記羽根車２１は、伝達部材の一例である。上記モータ２０と羽根車２１でレバー部材駆動部を構成している。   As shown in FIGS. 2 and 3, the lever tip 31 of the lever member 30 driven by the motor 20 is in contact with the lower hook 45 on the lower side of the latch member 40. Further, the shaft portion 21 a of the impeller 21 is connected to the drive shaft of the motor 20. The impeller 21 includes a shaft portion 21a and four blade portions 21b provided on the outer periphery of the shaft portion 21a in the circumferential direction and at equal intervals. The impeller 21 is an example of a transmission member. The motor 20 and the impeller 21 constitute a lever member driving unit.

図２,図３では、ドア２が閉じた状態で、ラッチ部材４０の上フック４３,下フック４５が係止部５１,５２に係止している。   In FIGS. 2 and 3, the upper hook 43 and the lower hook 45 of the latch member 40 are locked to the locking portions 51 and 52 with the door 2 closed.

次に、図４に従ってドア２の保持機構の動作を説明する。図４(a)はドア２が閉じて、ラッチ部材４０の上フック４３,下フック４５が係止部５１,５２に係止している状態を示しており、図４(b)はラッチ部材４０の上フック４３,下フック４５が係止部５１,５２から外れた状態を示している。上記係止部５１,５２は、本体ケーシング１側に設けられている。   Next, operation | movement of the holding mechanism of the door 2 is demonstrated according to FIG. 4A shows a state in which the door 2 is closed and the upper hook 43 and the lower hook 45 of the latch member 40 are engaged with the engaging portions 51 and 52, and FIG. 4B shows the latch member. 40 shows a state in which the upper hook 43 and the lower hook 45 are detached from the locking portions 51 and 52. The locking portions 51 and 52 are provided on the main casing 1 side.

図４(a),図４(b)に示すように、ラッチ部材４０は、ドア２に設けられたガイド溝(図示せず)により上下方向に案内される基部４１と、基部４１の上下方向に間隔をあけて側方(本体ケーシング１側)に延在する上アーム４２,下アーム４４と、上アーム４２の先端から下方に屈曲する上フック４３と、下アーム４４の先端から下方に屈曲する下フック４５とを有する。   As shown in FIGS. 4A and 4B, the latch member 40 includes a base 41 guided in a vertical direction by a guide groove (not shown) provided in the door 2, and a vertical direction of the base 41. The upper arm 42 and the lower arm 44 extending to the side (the body casing 1 side) with a gap therebetween, the upper hook 43 bent downward from the tip of the upper arm 42, and bent downward from the tip of the lower arm 44 And a lower hook 45.

図４(a)では、モータ２０により駆動される羽根車２１の羽根部２１ｂは、レバー部材３０の第１の面３０ａに接していない。ここで、レバー部材３０は、軸Ｏを中心に回動可能に支持されていると共に、バネ部材(図示せず)により反時計方向に付勢されて、レバー部材３０から上方に突出するレバー先端部３１が下フック４５の先端部に当接している。   In FIG. 4A, the blade portion 21 b of the impeller 21 driven by the motor 20 is not in contact with the first surface 30 a of the lever member 30. Here, the lever member 30 is supported so as to be rotatable about the axis O, and is biased counterclockwise by a spring member (not shown), and protrudes upward from the lever member 30. The part 31 is in contact with the tip of the lower hook 45.

そして、ドア２の操作表示部(図示せず)のドア開ボタンをユーザーが操作すると、モータ２０を駆動して、羽根車２１を所定角度回転させる。これにより、図４(a)の状態からモータ２０により羽根車２１を時計方向Ｒ１に回動させ、図４(b)に示すように、羽根車２１の羽根部２１ｂが、レバー部材３０の第１の面３０ａに接した後、レバー部材３０を押し上げて、レバー部材３０を軸Ｏを中心に反時計方向Ｒ２に回動させる。   When the user operates a door open button of an operation display section (not shown) of the door 2, the motor 20 is driven to rotate the impeller 21 by a predetermined angle. Thereby, the impeller 21 is rotated clockwise R1 by the motor 20 from the state of FIG. 4A, and the blade portion 21b of the impeller 21 is moved to the second position of the lever member 30 as shown in FIG. After contacting the first surface 30a, the lever member 30 is pushed up to rotate the lever member 30 about the axis O in the counterclockwise direction R2.

これにより、レバー部材３０のレバー先端部３１が下フック４５を押し上げる。そうして、ラッチ部材４０全体が上方向にスライドして、上フック４３,下フック４５が係止部５１,５２から外れ、ドア２が開く。   As a result, the lever tip 31 of the lever member 30 pushes up the lower hook 45. Then, the entire latch member 40 slides upward, the upper hook 43 and the lower hook 45 are disengaged from the locking portions 51 and 52, and the door 2 is opened.

ドア２が開くと、ラッチ部材４０は、フックバネの付勢力によって下方向に移動して、下側の位置に戻る。このとき、モータ２０により駆動される羽根車２１の羽根部２１ｂは、図４(a)のとおり、レバー部材３０の第１の面３０ａに接していない位置にする。   When the door 2 is opened, the latch member 40 moves downward by the biasing force of the hook spring and returns to the lower position. At this time, the blade portion 21b of the impeller 21 driven by the motor 20 is in a position not in contact with the first surface 30a of the lever member 30, as shown in FIG.

図５は上記電子レンジの後側かつ斜め上方から見た図を示しており、図６は上記電子レンジの縦断面図を示している。この図５,図６では、ラッチ部材４０の上フック４３,下フック４５が係止部５１,５２から外れた状態を示している(図４(b)参照)。   FIG. 5 shows a view of the microwave oven as viewed from the rear side and obliquely from above, and FIG. 6 shows a longitudinal sectional view of the microwave oven. 5 and 6 show a state in which the upper hook 43 and the lower hook 45 of the latch member 40 are disengaged from the locking portions 51 and 52 (see FIG. 4B).

また、図７は上記電子レンジのレバー部材３０を含む要部の斜視図を示している。レバー部材３０は、図７に示すように、外部からの手動操作による力が働く第２の面３０ｂを有している。   FIG. 7 shows a perspective view of the main part including the lever member 30 of the microwave oven. As shown in FIG. 7, the lever member 30 has a second surface 30 b on which a force by manual operation from the outside works.

図７において、３２,３３はレバー部材３０に設けられた軸部である。このレバー部材３０の軸部３２,３３によって、レバー部材３０は、本体ケーシング１に軸Ｏを中心に回動可能に支持されている。   In FIG. 7, 32 and 33 are shaft portions provided on the lever member 30. The lever member 30 is supported by the main body casing 1 by the shaft portions 32 and 33 of the lever member 30 so as to be rotatable about the axis O.

また、図８は上記電子レンジの手動操作用の補助レバー６０を含む要部の縦断面図を示している。図８は、ドア２が閉じた状態で、ラッチ部材４０の上フック４３,下フック４５が係止部５１,５２に係止している(図４(a),(b)参照)。   FIG. 8 is a longitudinal sectional view of the main part including the auxiliary lever 60 for manual operation of the microwave oven. In FIG. 8, the upper hook 43 and the lower hook 45 of the latch member 40 are locked to the locking portions 51 and 52 with the door 2 closed (see FIGS. 4A and 4B).

手動操作用の補助レバー６０は、図８に示すように、くの字形状をしており、ドア２に設けられた軸部６１により回動可能に支持されている。手動操作用の補助レバー６０は、軸部６１から前方に延びる第１アーム部６０ａと、軸部６１から後方かつ斜め上方に延びる第２アーム部６０ｂとを有する。   As shown in FIG. 8, the auxiliary lever 60 for manual operation has a dogleg shape and is rotatably supported by a shaft portion 61 provided on the door 2. The auxiliary lever 60 for manual operation includes a first arm portion 60 a extending forward from the shaft portion 61 and a second arm portion 60 b extending rearward and obliquely upward from the shaft portion 61.

上記補助レバー６０の第２アーム部６０ｂの先端は、ラッチ部材４０の第２の面３０ｂに当接している。補助レバー６０は、リンク機構の一例である。   The tip of the second arm portion 60 b of the auxiliary lever 60 is in contact with the second surface 30 b of the latch member 40. The auxiliary lever 60 is an example of a link mechanism.

図８において、ドア２の下側に設けられた貫通穴２ａを通して、棒状の工具などを矢印Ｒ３の方向に挿入して、第２アーム部６０ｂを押し上げると、図９に示すように、補助レバー６０が軸部６１を中心に時計方向に回動する。そうして、補助レバー６０の第２アーム部６０ｂの先端は、ラッチ部材４０の第２の面３０ｂを押し上げて、レバー部材３０を反時計方向に回動させる。   In FIG. 8, when a rod-shaped tool or the like is inserted in the direction of the arrow R3 through the through hole 2a provided on the lower side of the door 2 and the second arm portion 60b is pushed up, the auxiliary lever as shown in FIG. 60 rotates around the shaft 61 in the clockwise direction. Then, the tip of the second arm portion 60b of the auxiliary lever 60 pushes up the second surface 30b of the latch member 40 and rotates the lever member 30 counterclockwise.

これによって、レバー部材３０のレバー先端部３１が下フック４５を押し上げる。そうして、ラッチ部材４０全体が上方向にスライドして、上フック４３,下フック４５が係止部５１,５２から外れ、ドア２が開く。   As a result, the lever tip 31 of the lever member 30 pushes up the lower hook 45. Then, the entire latch member 40 slides upward, the upper hook 43 and the lower hook 45 are disengaged from the locking portions 51 and 52, and the door 2 is opened.

上記構成の電子レンジによれば、レバー部材３０の第１の面３０ａにモータ２０の回転力を作用させると、レバー部材３０が回動してラッチ部材４０を上方向に押し上げ、ラッチ部材４０を係止部５１,５２から外す。一方、停電などによりモータ２０でレバー部材３０を回動できない場合は、図８,図９に示すように、レバー部材３０の第２の面３０ｂに外部からの手動操作による力を作用させると、レバー部材３０が回動してラッチ部材４０を上方向に押し上げ、ラッチ部材４０を係止部５１,５２から外す。このように、簡単な構成で小型のモータ２０および手動操作の両方でレバー部材３０を回動させて、ラッチ部材４０を解除させることができる。   According to the microwave oven having the above configuration, when the rotational force of the motor 20 is applied to the first surface 30a of the lever member 30, the lever member 30 rotates to push the latch member 40 upward, Remove from the locking portions 51, 52. On the other hand, when the lever member 30 cannot be rotated by the motor 20 due to a power failure or the like, as shown in FIGS. 8 and 9, when a force by manual operation from the outside is applied to the second surface 30 b of the lever member 30, The lever member 30 rotates to push the latch member 40 upward, and the latch member 40 is removed from the locking portions 51 and 52. In this way, the latch member 40 can be released by rotating the lever member 30 with both a small motor 20 and manual operation with a simple configuration.

なお、上記レバー部材３０の第１の面３０ａを利用して、モータ２０のみでレバー部材３０を回動させる電子レンジを構成してもよいし、レバー部材３０の第２の面３０ｂを利用して、手動操作のみでレバー部材３０を回動させる電子レンジを構成してもよく、どちらの電子レンジにおいても同じレバー部材３０を用いることで共通化が図れる。   A microwave oven in which the lever member 30 is rotated only by the motor 20 may be configured by using the first surface 30a of the lever member 30, or the second surface 30b of the lever member 30 may be used. Thus, a microwave oven that rotates the lever member 30 only by manual operation may be configured, and in either microwave oven, the same lever member 30 can be used for common use.

また、上記モータ２０の回転力を伝達部材２１を介してレバー部材３０の第１の面３０ａに伝達することによってレバー部材３０を回動させるので、モータ２０の回転力でラッチ部材４０を係止部５１,５２から容易に外すことができる。   Further, since the lever member 30 is rotated by transmitting the rotational force of the motor 20 to the first surface 30a of the lever member 30 via the transmission member 21, the latch member 40 is locked by the rotational force of the motor 20. It can be easily removed from the parts 51 and 52.

また、外部からの手動操作による力をリンク機構を介してレバー部材３０の第２の面３０ｂに回転力として伝達することによってレバー部材３０を回動させるので、手動操作による力でラッチ部材４０を係止部５１,５２から容易に外すことができる。   In addition, since the lever member 30 is rotated by transmitting a force due to manual operation from the outside as a rotational force to the second surface 30b of the lever member 30 via the link mechanism, the latch member 40 is moved by force due to manual operation. It can be easily removed from the locking portions 51 and 52.

この発明および実施形態をまとめると、次のようになる。   The present invention and the embodiment are summarized as follows.

この発明の一態様に係る加熱調理器は、
本体ケーシング１と、
上記本体ケーシング１の開口部を開閉するドア２と、
上記本体ケーシング１側に設けられた係止部５１,５２と、
上記ドア２に設けられ、上記ドア２を閉めた状態で上記本体ケーシング１側の上記係止部５１,５２に係止するラッチ部材４０と、
上記本体ケーシング１に回動可能に取り付けられ、モータ２０の回転力が作用可能な第１の面３０ａと、外部からの手動操作による力が作用可能な第２の面３０ｂとを有するレバー部材３０と
を備え、
上記レバー部材３０の上記第１の面３０ａに上記モータ２０の回転力が作用するか、または、上記レバー部材３０の上記第２の面３０ｂに上記外部からの手動操作による力が作用して、上記ラッチ部材４０が回動することによって、上記ラッチ部材４０を移動させて上記係止部５１,５２から外すことを特徴とする。 The cooking device according to one aspect of the present invention is:
A body casing 1;
A door 2 for opening and closing the opening of the main casing 1;
Locking portions 51 and 52 provided on the main casing 1 side;
A latch member 40 provided on the door 2 and locked to the locking portions 51 and 52 on the main body casing 1 side with the door 2 closed;
A lever member 30 that is rotatably attached to the main body casing 1 and has a first surface 30a on which the rotational force of the motor 20 can act and a second surface 30b on which a force by manual operation from the outside can act. And
The rotational force of the motor 20 acts on the first surface 30a of the lever member 30, or the force by manual operation from the outside acts on the second surface 30b of the lever member 30, When the latch member 40 is rotated, the latch member 40 is moved and removed from the locking portions 51 and 52.

上記構成によれば、レバー部材３０の第１の面３０ａにモータ２０の回転力が作用して、レバー部材３０が回動すると、ラッチ部材４０を移動させて係止部５１,５２から外す一方、レバー部材３０の第２の面３０ｂに外部からの手動操作による力が作用して、レバー部材３０が回動すると、ラッチ部材４０を移動させて係止部５１,５２から外す。このように、簡単な構成で小型のモータ２０および手動操作の両方でレバー部材３０を回動させて、ラッチ部材４０を解除させることができる。   According to the above configuration, when the rotation force of the motor 20 acts on the first surface 30a of the lever member 30 and the lever member 30 rotates, the latch member 40 is moved and removed from the locking portions 51 and 52. When the lever member 30 is rotated by an external manual force applied to the second surface 30b of the lever member 30, the latch member 40 is moved and removed from the locking portions 51 and 52. In this way, the latch member 40 can be released by rotating the lever member 30 with both a small motor 20 and manual operation with a simple configuration.

なお、上記レバー部材３０の第１の面３０ａを利用して、モータ２０のみでレバー部材３０を回動させる加熱調理器を構成してもよいし、レバー部材３０の第２の面３０ｂを利用して、手動操作のみでレバー部材３０を回動させる加熱調理器を構成してもよく、どちらの加熱調理器においても同じレバー部材３０を用いることで共通化が図れる。   In addition, you may comprise the heating cooker which rotates the lever member 30 only with the motor 20 using the 1st surface 30a of the said lever member 30, or the 2nd surface 30b of the lever member 30 is utilized. And the cooking device which rotates the lever member 30 only by manual operation may be comprised, and commonality can be aimed at by using the same lever member 30 in either heating cooking device.

また、一実施形態の加熱調理器では、
上記モータ２０と、
上記モータ２０の回転力を上記レバー部材３０の上記第１の面３０ａに伝達する伝達部材２１と
を備えた。 Moreover, in the heating cooker of one embodiment,
The motor 20;
A transmission member 21 that transmits the rotational force of the motor 20 to the first surface 30a of the lever member 30 is provided.

上記実施形態によれば、モータ２０の回転力を伝達部材２１を介してレバー部材３０の第１の面３０ａに伝達することによってレバー部材３０を回動させるので、モータ２０の回転力でラッチ部材４０を係止部５１,５２から容易に外すことができる。   According to the above embodiment, the lever member 30 is rotated by transmitting the rotational force of the motor 20 to the first surface 30a of the lever member 30 via the transmission member 21, so that the latch member is driven by the rotational force of the motor 20. 40 can be easily removed from the locking portions 51 and 52.

また、一実施形態の加熱調理器では、
上記外部からの手動操作による力を上記レバー部材３０の上記第２の面３０ｂに回転力として伝達するリンク機構を備えた。 Moreover, in the heating cooker of one embodiment,
A link mechanism is provided that transmits a force generated by manual operation from the outside to the second surface 30b of the lever member 30 as a rotational force.

上記実施形態によれば、外部からの手動操作による力をリンク機構を介してレバー部材３０の第２の面３０ｂに回転力として伝達することによってレバー部材３０を回動させるので、手動操作による力でラッチ部材４０を係止部５１,５２から容易に外すことができる。   According to the above-described embodiment, the lever member 30 is rotated by transmitting the force due to manual operation from the outside to the second surface 30b of the lever member 30 via the link mechanism as the rotational force. Thus, the latch member 40 can be easily removed from the locking portions 51 and 52.
