A sensor unit provided at the rear of the grill storage to detect the presence or absence of the cooking container,
The sensor unit is elastically urged by an elastic urging member so as to protrude toward the inside of the grill container, and contacts the rear portion of the cooking container in a state in which the cooking container support is stored in the grill container. The present invention relates to a detection body that moves backward when hitting, and a grill configured to include a detection unit that detects the backward movement of the detection body.

  Such a grill is mainly mounted on a gas stove, and is provided with a sensor unit provided at the rear of the grill storage to detect the presence or absence of the cooking container. For example, the cooking container is stored in the grill storage. If not, it is possible to perform control for improving safety and convenience, such as restraining the combustion of the grill burner.

  As a conventional example of the sensor unit, a two-stage tube having a small-diameter tube portion and a large-diameter tube portion at the tip of a cylindrical support attached to the rear wall portion of the grill cabinet so as to protrude into the grill cabinet. A detection body formed in a shape is provided, and a coil spring as an elastic urging member is disposed inside the detection body, and at a rear end side portion of the cylindrical support that extends outward of the grill storage. And a detection unit (for example, see Patent Document 1).

That is, from the rear end portion along the grill cabinet front-rear width direction, where the cylindrical support extends through the rear wall portion of the grill cabinet and protrudes into the inside of the grill cabinet, A sensor support frame configured to have a long L-shape including a rear end portion extending along the width direction of the grill warehouse, and supporting a front end portion of the tubular support body with respect to a rear wall portion of the grill warehouse. Is provided.
The detection body is formed in a two-stage cylindrical shape including a large-diameter cylindrical portion on the front end side and a small-diameter cylindrical portion on the rear end side, and in addition, closes the distal end opening of the large-diameter cylindrical portion of the detection body. A bottomed cylindrical contact portion to be fitted to the outside is provided.

A ring-shaped (annular) spring receiver having an outer diameter larger than the inner diameter of the small-diameter cylindrical portion of the main body of the detection body and slightly smaller than the inner diameter of the large-diameter cylindrical portion is attached to the tip of the cylindrical support. ing.
Then, the movement of the small-diameter cylindrical portion of the detection body toward the distal end of the cylindrical support is received by the spring receiver, and the large-diameter cylindrical portion is jacketed by the spring receiver. A coil spring as an elastic urging member is disposed in a compressed state between the spring receiver and the spring receiving member.

  In other words, the detecting body is returned and urged by the coil spring to the projecting position where the step between the small-diameter tubular portion and the large-diameter tubular portion is received by the spring receiving portion, and the cooking container supporting portion is stored in the grill storage. Then, it is configured to be pressed by the rear portion of the cooking container (grill dish) and to be moved backward while being guided by the spring receiver, against the return biasing force of the coil spring.

JP-A-2006-16300

  In the conventional grill, since the detecting body is formed in a two-stage cylindrical shape having a large-diameter cylindrical part and a small-diameter cylindrical part, it has a complicated configuration, and moreover, has a large-diameter cylindrical part of the detecting body. A coil spring as an elastic biasing member is arranged in a compressed state between the contact portion of the detection body and the spring receiver in a manner to cover the spring receiver mounted on the distal end of the cylindrical support. Therefore, the installation configuration of the detection body is complicated due to the complicated arrangement configuration of the coil spring and the like.

  In addition, a switch body provided with a reed switch and a magnet are installed at an intermediate position in the longitudinal direction of the rear end side portion of the L-shaped long cylindrical support as a detection unit for detecting the backward movement of the detection body. The cord extending from the contact portion of the detection body extends through the inside of the tubular support to the installation location of the detection unit, and the extension end of the cord has a switch body and a magnet. Since the magnetic shield is mounted in a state where it can move freely through the gap, the location where the detector is installed from the contact part of the detector through the inside of the cylindrical support to detect the retreat movement of the detector The structure for detecting the retreating movement of the detection body is complicated due to the necessity of a cord-like body extending to the other side.

  That is, in the conventional grill, the configuration of the detector and the installation configuration thereof are complicated, and the configuration for detecting the backward movement of the detector is complicated. Since the sensor unit for detecting the noise has a complicated configuration, improvement has been desired.

  The present invention has been made in view of the above situation, and an object of the present invention is to provide a grill that can simplify a sensor unit that detects the presence or absence of a cooking container.

A grill of the present invention, a cooking container support portion that is provided so as to be able to move out and into the grill storage through a front opening of the grill storage and is capable of mounting a cooking container,
A sensor unit provided at the rear of the grill storage to detect the presence or absence of the cooking container,
The sensor unit is elastically urged by an elastic urging member so as to protrude toward the inside of the grill container, and contacts the rear portion of the cooking container in a state in which the cooking container support is stored in the grill container. Detecting body that moves backward by hitting, and is configured to include a detecting unit that detects the backward movement of the detecting body, and the characteristic configuration thereof is as follows.
The detection body is formed in a columnar shape penetrating the rear wall portion of the grill storage and protruding into the grill storage, and is provided with a large diameter portion at an intermediate position in a longitudinal direction,
A sensor support frame having an outer side wall and an inner side wall spaced apart in the perspective direction with respect to the rear wall is provided so as to be attachable to an outer surface of the rear wall,
On the outer side wall portion, an outer side insertion hole for inserting the detection body is provided,
The inner side wall portion is provided with an inner side insertion hole for inserting the detection body and a receiving portion for receiving movement of the large diameter portion toward the rear wall portion,
The detection unit is mounted on the sensor support frame,
A portion of the detection body that is located closer to the side of the outer side wall than the large-diameter portion has a detection target frame including a detection target detected by the detection unit. Movement to the approaching side is externally fitted in a state of being supported and received by the large diameter portion,
A coil spring as the elastic urging member is disposed between the outer side wall portion and the frame to be detected.
In addition, the above-mentioned column shape means a solid linear column or a hollow linear cylinder.

  That is, a detection body having a cylindrical shape and having a large-diameter portion at an intermediate position in a longitudinal direction is provided with an outer side through-hole of an outer side wall portion of a sensor support frame mounted on an outer surface side of a rear wall portion of a grill warehouse. And it is attached to the sensor support frame in a state of being inserted through the inner side insertion hole of the inner side wall portion.

  The detection target frame provided with the detection target detected by the detection unit attached to the sensor support frame approaches the inner side wall portion to a portion of the detection body located on the outer side wall portion side with respect to the large diameter portion. A coil spring as an elastic urging member is disposed between the outer side wall portion and the frame to be detected, while being outwardly fitted while being supported and received by the large-diameter portion. I have.

  When the frame to be detected is pressed and moved toward the inner side wall by the coil spring, the detection body is moved to the rear wall side, and the large diameter portion of the detection body becomes the receiving portion of the inner side wall. In this state, the detector that penetrates the rear wall of the grill storage and projects into the interior of the grill storage protrudes greatly into the interior of the grill storage.

  When the detection container is retracted by contact with the rear portion of the cooking container by the cooking container supporting portion being stored in the grill storage, the detection target frame externally fitted to the detection member is moved backward by the detection member. As a result, the detector moves backward to the side away from the inner side wall portion, and as a result, the detector detects the detected portion provided on the frame to be detected, thereby detecting the retreat movement of the detected object. become.

Therefore, it is possible to simplify the sensor unit for detecting the presence or absence of the cooking container.
That is, the detection body having a cylindrical shape and having a large-diameter portion at an intermediate position in the longitudinal direction has a simple configuration.
In addition, the detection body is inserted and supported in a sensor support frame having an inner side wall part and an outer side wall part, and an elastic biasing member is provided between the detection target frame body fitted to the detection body and the outer side wall part. Since the coil spring is disposed as a unit and the detection unit is mounted on the sensor support frame, the installation configuration of the detection body can be simplified, and the coil spring and the cover are used to detect the backward movement of the detection body. The configuration for installing the detection frame and the detection unit can also be simplified.

  Therefore, the configuration of the detection body and its installation configuration are simple, and the configuration for detecting the retreat movement of the detection body is a simple configuration. Therefore, the sensor unit for detecting the presence or absence of the cooking container has a simple configuration. can do.

  In short, according to the characteristic configuration of the grill of the present invention, it is possible to simplify the sensor unit for detecting the presence or absence of the cooking container.

A further characteristic configuration of the grill of the present invention is that the sensor support frame includes a main body frame portion including a connection wall portion connected to the outer side wall portion and the rear wall portion, and the inner side wall portion and the main body frame portion. And an auxiliary frame portion having a connection wall portion connected to the
The present invention is characterized in that the coil spring is provided so as to cover the detection body.

That is, when assembling the detection body, the frame to be detected, and the coil spring to the sensor support frame, the detection body to which the frame to be detected is externally mounted and the coil spring is mounted in a jacketed state is used. The auxiliary frame is attached to the auxiliary frame while being inserted through the inner side insertion hole of the inner side wall of the auxiliary frame.
Next, the auxiliary frame supporting the frame to be detected and the detection body on which the coil spring is mounted is moved closer to the outer side wall, and the coil spring is compressed by contact with the outer side wall. While deforming, the detection body is inserted into the outer side insertion hole of the outer side wall, and then the connection wall is connected to the main body frame, so that the detection body, the frame to be detected, and the coil spring are connected. It can be assembled to the sensor support frame.

  As described above, while the detection body on which the frame to be detected and the coil spring are mounted is supported by the auxiliary frame portion, the detection body is inserted into the outer side insertion hole of the outer side wall portion, and the auxiliary frame portion is By connecting the connection wall portion to the main body frame portion, the detection body, the frame to be detected, and the coil spring can be assembled to the sensor support frame at once, so that the presence or absence of the cooking container is detected. The assembling work of the sensor unit can be performed favorably.

  The sensor support frame to which the detection body, the frame to be detected, and the coil spring are assembled is attached to the rear of the grill warehouse by connecting the connection wall of the main frame to the rear wall of the grill warehouse. Also, if the connecting wall of the main body frame is removed from the rear wall of the grill storage, the sensor support frame can be removed from the rear of the grill storage for maintenance or the like. The operation of attaching / detaching the sensor unit for detecting to / from the grill storage can also be performed favorably.

  In addition, since the frame to be detected, which is externally fitted to the detector, is located on the inner side wall of the coil spring provided so as to cover the detector, the rear wall of the grill storage can be detected. Even if the cooking exhaust gas in the grill chamber flows through the body insertion point or the inner side insertion hole of the inner side wall, the cooking exhaust gas is received by the detection target frame, and the coil is received. Since it is possible to suppress the cooking exhaust from falling on the spring, it is possible to suppress the coil spring from being damaged such as rusting due to the cooking exhaust.

  In short, according to the further characteristic configuration of the grill of the present invention, the assembling work for assembling the sensor unit for detecting the presence or absence of the cooking vessel and the attaching and detaching work for attaching and detaching to and from the rear wall of the grill cabinet can be performed well. Moreover, damage to the coil spring can be suppressed.

A further characteristic configuration of the grill of the present invention is such that the detection body is rotatably inserted around the axial center along the longitudinal direction with respect to the outer insertion hole and the inner insertion hole,
The frame to be detected is fitted around the detection body so as to be relatively rotatable,
Between the frame to be detected and the auxiliary frame portion, the frame to be detected is allowed to move along the longitudinal direction of the detection body, and is rotated around an axis along the longitudinal direction of the detection body. Is provided with a rotation preventing portion for preventing the rotation.

  That is, the detection body is rotatably inserted around the axial center along the longitudinal direction into the inner insertion hole and the outer insertion hole of the sensor support frame, and the detection target frame is inserted into the detection body. Since the detection body is rotatably fitted to the outer periphery of the detection body, even if the detection body receives a force that rotates around an axis along the longitudinal direction due to contact with the cooking container, the detection body is moved in the longitudinal direction. By rotating the detection body around the axis, the deformation damage of the detection body can be suppressed.

  Moreover, since the frame to be detected is fitted to the detection body so as to be rotatable relative to the detection body, heat from the detection body is applied to the frame to be detected between the detection body and the frame to be detected. Since there is a gap that is difficult to be transmitted, the heat of the detector, which is in a high temperature state due to contact with the cooking container, is difficult to be transmitted to the frame to be detected. As a result, the frame to be detected is in a high temperature state. As a result, it is possible to suppress that the detection target portion provided in the detection target frame body becomes high temperature and the detection operation of the detection unit becomes unstable, thereby enabling the detection unit to perform an appropriate detection operation. .

  That is, for example, in a case where the detected portion is a magnet and the detecting portion is configured as a reed switch for detecting a magnetic force, when the temperature of the magnet as the detected portion becomes high, the magnetic force is reduced, and the reed switch as the detecting portion is reduced. May cause inconvenience that it is difficult to perform an appropriate detection operation.However, since it is possible to suppress the frame to be detected from becoming a high temperature state, it is necessary to perform an appropriate detection operation using a reed switch as a detection unit. Can be.

  Further, between the frame to be detected and the auxiliary frame portion, the frame to be detected is allowed to move along the longitudinal direction of the detector, and is prevented from rotating around the axis along the longitudinal direction of the detector. Since the rotation preventing portion is provided, the rotation phase around the axis along the longitudinal direction of the detection target frame body can be maintained at an appropriate rotation phase, so that the detection operation of the detection target portion by the detection portion is performed by the detection portion. Can be done properly

  In short, according to the further feature configuration of the grill of the present invention, it is possible to suppress deformation and damage of the detection body and to perform an appropriate detection operation in the detection unit.

A further characteristic configuration of the grill of the present invention is that an outer cylindrical portion is provided at a hole edge of the outer insertion hole, the outer cylindrical portion protruding toward a side where the inner side wall exists.
The present invention is characterized in that an end of the coil spring on the side where the outer side wall portion exists is fitted to the outer side cylindrical portion.

That is, at the hole edge of the outer insertion hole, since the outer cylinder portion is provided to protrude toward the existing side of the inner side wall portion, in contacting and supporting the detection body in the outer insertion hole, Since the contact surface increases, the detection body can be appropriately contacted and supported.
In addition, since the end of the outer side wall of the coil spring on the existing side is fitted to the outer tube, the outer tube is used to position and hold the end of the coil spring. Thereby, the coil spring can be appropriately positioned in an appropriate mounting state.

  By the way, in order to form the outer cylindrical portion protruding on the side where the inner side wall portion is present at the hole edge of the outer insertion hole, for example, when the outer side wall portion is formed of a metal plate, The outer cylindrical portion can be easily formed at the edge of the outer insertion hole, for example, by being formed by burring.

  In short, according to the characteristic configuration of the grill of the present invention, the detection body can be appropriately contacted and supported, and the coil spring can be appropriately positioned in an appropriate mounting state.

A further characteristic configuration of the grill of the present invention is provided at an edge of the inner side insertion hole, an inner side cylindrical portion protruding to the side where the outer side wall exists,
The receiving part is formed at the tip of the inner cylindrical part.

That is, since the inner side cylindrical portion protruding toward the existence side of the outer side wall portion is provided at the hole edge of the inner side insertion hole, in contacting and supporting the detection body with the inner side insertion hole, Since the contact surface increases, the detection body can be appropriately contacted and supported.
In addition, since the receiving portion for receiving the large-diameter portion of the detection body is formed using the tip of the inner cylindrical portion, the receiving portion can be formed with a simple configuration.

  By the way, in order to form the inner cylindrical portion protruding to the side where the outer side wall portion is present at the edge of the inner insertion hole, for example, when the inner side wall portion is formed of a metal plate, The inner cylindrical portion can be easily formed at the edge of the inner insertion hole, for example, by easily performing the burring process.

  In short, according to the further feature configuration of the grill of the present invention, the detection body can be appropriately contacted and supported, and the receiving portion can be formed with a simple configuration.

A further characteristic configuration of the grill of the present invention is that the detection body is formed of a metal and a cylindrical tubular body,
The large diameter portion is formed in a state where a peripheral wall portion of the cylindrical body is bulged annularly.

That is, since the detection body is formed of a cylindrical body made of metal, the cost of the detection body can be reduced, for example, by using a commercially available cylinder.
In addition, since the large-diameter portion is formed in a state in which the peripheral wall portion of the cylindrical body is annularly swelled, the cost of the detection body can be further reduced. In other words, since the peripheral wall portion of the cylindrical body can be bulged annularly by bulging, the large-diameter portion with the peripheral wall portion of the cylindrical body bulged annularly can be formed while reducing the manufacturing cost. Can be.

  In short, according to the further characteristic configuration of the grill of the present invention, the cost of the detection body can be reduced.

A further characteristic configuration of the grill of the present invention is provided with a closing plate that covers the periphery of the insertion portion of the detection body in a state along the inner surface of the rear wall portion on the inner side of the grill storage,
The present invention is characterized in that a tubular body that covers the detection body is provided on the closing plate so as to protrude inward of the grill storage.

  That is, a closing plate is provided to cover the periphery of the insertion portion of the detection body along the inner surface of the rear wall portion on the inner side of the grill storage, and a tubular body that covers the detection body is provided in the closing plate. Since it is provided so as to protrude to the side, it is possible to appropriately suppress the cooking exhaust gas in the grill warehouse from flowing to the sensor support frame side through the insertion portion of the detection body in the rear wall portion of the grill warehouse.

  In other words, since the tubular body that covers the detector is provided on the closing plate that covers the periphery of the detection body along the inner surface of the grill storage so as to protrude inward of the grill storage, In order for the cooking exhaust gas to flow to the sensor support frame side through the insertion portion of the detection body in the rear wall portion of the grill chamber, it flows through between the inner surface of the cylindrical body and the outer surface of the detection body, and then forms on the closing plate. Since the cooking exhaust gas in the grill chamber is unlikely to flow to the sensor support frame side because it is necessary to flow through the inserted portion of the detected object, the cooking exhaust gas in the grill chamber flows to the sensor support frame side. Can be appropriately suppressed.

  In short, according to the further characteristic configuration of the grill of the present invention, it is possible to appropriately suppress the cooking exhaust gas in the grill storage from flowing to the sensor support frame side.
