It is characterized by moving.

  In this electric stove, the guard member heated in the region on the front side of the reflecting plate to which the heat radiated from the heater hits moves to the region on the rear side of the reflecting plate to which the heat radiated from the heater does not hit. Therefore, the guard member can be prevented from reaching a high temperature by moving the guard member back and forth between the area on the front side of the reflector and the area on the rear side of the reflector.

  An electric stove according to a second aspect of the invention is the electric stove according to the first aspect of the invention, wherein the guard member is disposed so as to surround the heater and the reflector, and the periphery of the heater and the reflector It is characterized by rotating.

  In this electric stove, all of the guard members go back and forth between the region on the front side of the reflector and the region on the rear side of the reflector, so that it is easy to prevent the guard member from becoming hot. In addition, when the guard member is configured to reciprocate around the heater and the reflector, for example, the portion that has finally moved from the front region to the rear region is the first to the front region from the rear region. The cooling efficiency of the guard member is poor because it moves to the area, but in this electric stove, the guard member rotates around the heater and the reflector, so it finally moved from the front area to the rear area. The part finally moves from the rear area to the front area. Therefore, the cooling efficiency of the guard member is high. In addition, since the guard member is disposed so as to surround the periphery of the heater and the reflecting plate and rotates around the heater and the reflecting plate, the electric stove is prevented from being enlarged and the front side of the reflecting plate is suppressed. All of the guard members can be moved back and forth between the area and the area behind the reflector.

  An electric stove according to a third aspect of the invention is the electric stove according to the first or second aspect of the invention, further comprising detection means for detecting a drive abnormality of the guard member, wherein the detection means detects a drive abnormality of the guard member. In this case, the driving of the guard member is stopped.

  In this electric stove, when a driving abnormality occurs in the guard member due to a user's finger being caught in the guard member, the driving of the guard member is stopped, so that the safety is high.

  An electric stove according to a fourth invention is characterized in that, in the electric stove according to the third invention, the heater is stopped when the driving of the guard member is stopped.

  In this electric stove, when the driving of the guard member is stopped, the heater is stopped, so that the safety is high.

  As described above, according to the present invention, the following effects can be obtained.

  In the first aspect of the invention, the guard member heated in the region on the front side of the reflecting plate to which the heat radiated from the heater hits moves to the region on the rear side of the reflecting plate to which the heat radiated from the heater does not hit. Therefore, it is possible to prevent the guard member from reaching a high temperature by moving the guard member back and forth between the area on the front side of the reflector and the area on the rear side of the reflector.

  In the second aspect of the invention, all of the guard members go back and forth between the region on the front side of the reflector and the region on the rear side of the reflector, so that it is easy to prevent the guard member from becoming hot. In addition, when the guard member is configured to reciprocate around the heater and the reflector, for example, the portion that has finally moved from the front region to the rear region is the first to the front region from the rear region. The cooling efficiency of the guard member is poor because it moves to the area, but in this electric stove, the guard member rotates around the heater and the reflector, so it finally moved from the front area to the rear area. The part finally moves from the rear area to the front area. Therefore, the cooling efficiency of the guard member is high. In addition, since the guard member is disposed so as to surround the periphery of the heater and the reflecting plate and rotates around the heater and the reflecting plate, the electric stove is prevented from being enlarged and the front side of the reflecting plate is suppressed. All of the guard members can be moved back and forth between the area and the area behind the reflector.

  In the third aspect of the invention, the driving of the guard member is stopped when a driving abnormality occurs in the guard member due to a user's finger being caught in the guard member.

  In 4th invention, when a guard member's drive stops, since a heater stops, safety | security is high.

It is a figure when the electric stove concerning the embodiment of the present invention is seen from the front upper part. It is a horizontal sectional view of the electric heater shown in FIG. It is a control block diagram of the electric stove shown in FIG. It is the schematic of the electric heater concerning the modification of this invention, (a) is a guard member in the center of the area | region ahead of a reflector, (b) is a guard member ahead of a reflector. When moving to the right side of the side area, (c) shows the case where the guard member has moved to the left side of the area on the front side of the reflector.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 3, the electric stove 1 of the present embodiment includes a casing 2, a base 3, a heater 4, a reflector 5, a guard member 6, a detection sensor 7 (detection means), a drive unit 8, and a control. Part 10 and the like.

  The casing 2 extends in the vertical direction, and has a substantially rectangular opening on the front surface. A base 3 is disposed below the casing 2. Although not shown in FIG. 1, a top plate is disposed above the casing 2, and the upper portion of the casing 2 is closed.

  The heater 4 (heating element) is a sheathed heater formed in a rod shape. The heater 4 extends in the casing 2 in parallel with the longitudinal direction of the casing 2. That is, it extends along the vertical direction. The heater 4 is not limited to a sheathed heater, and may be a quartz tube heater, a ceramic heater, or the like.

  The reflector 5 is disposed behind the heater 4 and reflects heat radiated from the heater 4 forward. The reflecting plate 5 extends in the casing 2 in parallel with the longitudinal direction of the casing 2. That is, it extends along the vertical direction. As shown in FIG. 2, the reflection plate 5 is curved so as to cover the rear side of the heater 4 and both left and right sides. As shown in FIG. 2, the front region on the front side of the reflector 5 is a region where the heat of the heater 4 is applied, and the rear region on the rear side of the reflector 5 is a region where the heat of the heater 4 is not applied. is there.

  The guard member 6 is formed, for example, in a mesh shape (or may be a wire shape) with a metal wire, and serves as a safety guard that prevents the user from touching the heater 4 directly. As shown in FIGS. 1 and 2, the guard member 6 is disposed so as to surround the heater 4 and the reflection plate 5, and has a circular shape in a horizontal sectional view. Therefore, the guard member 6 is disposed across a region on the front side of the reflection plate 5 and a region on the rear side of the reflection plate 5. The guard member 6 is rotationally driven by a drive unit 8 having a motor or the like so as to continuously rotate around the heater 4 and the reflection plate 5 in one direction. Accordingly, the entire area of the guard member 6 is repeatedly moved alternately between a region on the front side of the reflecting plate 5 and a region on the rear side of the reflecting plate 5. Therefore, the guard member 6 alternately repeats a state in which it is heated by the heat radiated from the heater 4 and a state in which it is cooled without being exposed to the heat radiated from the heater 4.

  The detection sensor 7 (detection means) is a sensor that detects a drive abnormality of the guard member 6. The detection sensor 7 is disposed, for example, between the guard member 6 and the casing 2, and detects an abnormality in driving of the guard member 6 by measuring the time for which the guard member 6 rotates or the rotation speed of the guard member 6. doing. Therefore, when the user stops the rotation of the guard member 6 by pinching a finger between the wires of the safety guard, or when the rotation speed of the guard member 6 becomes slower than normal, the drive abnormality is caused. Can be detected.

  The control unit 10 is electrically connected to the above-described heater 4, detection sensor 7, drive unit 8, and the like. The control unit 10 stops the drive unit 8 and stops the driving of the guard member 6 when receiving a signal about the drive abnormality from the detection sensor 7. Further, the control unit 10 stops the heater 4 when the driving of the guard member 6 is stopped.

<Characteristics of the electric heater according to this embodiment>
The electric heater 1 according to this embodiment has the following characteristics.

  In the electric stove 1 of the present embodiment, the guard member 6 heated in the region ahead of the reflecting plate 5 to which the heat radiated from the heater 4 hits is more than the reflecting plate 5 to which the heat radiated from the heater 4 does not hit. Since it is cooled by moving to the rear region, the guard member 6 is moved back and forth between the region on the front side of the reflecting plate 5 and the region on the rear side of the reflecting plate 5. It can prevent becoming high temperature.

  Moreover, in the electric heater 1 of this embodiment, since all the guard members 6 go back and forth between the region on the front side of the reflecting plate 5 and the region on the rear side of the reflecting plate 5, the guard member 6 becomes hot. It is easy to prevent. Further, in the case where the guard member 6 is configured to reciprocate around the heater 4 and the reflecting plate 5, for example, the part that has finally moved from the front region to the rear region is first from the rear region. Although the cooling efficiency of the guard member 6 is poor because it moves to the area on the front side, in this electric heater 1, since the guard member 6 rotates around the heater 4 and the reflector 5, the area on the front side is finally included. The portion that moved from the rear region to the rear region finally moves from the rear region to the front region. Therefore, the cooling efficiency of the guard member 6 is high. Moreover, since the guard member 6 is disposed so as to surround the heater 4 and the reflector 5 and rotates around the heater 4 and the reflector 5, the reflection of the electric heater 1 is suppressed while suppressing an increase in size. All of the guard members 6 can be moved back and forth between the area on the front side of the plate 5 and the area on the rear side of the reflecting plate 5.

  Moreover, in the electric stove 1 of this embodiment, when a driving abnormality occurs in the guard member 6 due to a user's finger being caught in the guard member 6, the driving of the guard member 6 is stopped, so that the safety is high. .

  Moreover, in the electric stove 1 of this embodiment, when the drive of the guard member 6 stops, the heater 4 stops, so that safety is high.

  As mentioned above, although embodiment of this invention was described based on drawing, it should be thought that a specific structure is not limited to these embodiment. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes meanings equivalent to the scope of claims for patent and all modifications within the scope.

  In the above-described embodiment, the guard member 6 is disposed so as to surround the heater 4 and the reflection plate 5 and rotates around the heater 4 and the reflection plate 5. If it moves between the area | region ahead of a board and the area | region behind the reflector, it will not be limited to the structure. For example, as shown in FIGS. 4A to 4C, the guard member 16 is disposed across a region on the front side of the reflecting plate 5 and a region on the rear side of the reflecting plate 5. Even if the guard member 16 is reciprocated left and right so that at least a part of the guard member 16 moves between a region on the front side of the reflecting plate 5 and a region on the rear side of the reflecting plate 5. Good. However, the guard member 16 needs to be always in the entire region in front of the reflector 5 so that the user cannot directly contact the heater 4 while being driven.

  Moreover, in the above-mentioned embodiment, although the whole region of the guard member 6 demonstrated between the area | region of the front side rather than the reflecting plate 5, and the area | region of the rear side rather than the reflecting plate 5, it explained at least the guard member. A part may be configured to move between a region in front of the reflector and a region in rear of the reflector.

  Moreover, in the above-mentioned embodiment, when the driving abnormality of the guard member 6 is detected, the driving of the guard member 6 is stopped. However, the driving of the guard member may not be stopped, or the driving abnormality of the guard member is not performed. It is not necessary to have a detecting means for detecting.

  In the above-described embodiment, the heater 4 is stopped when the driving of the guard member 6 is stopped. However, the heater 4 may not be stopped.

  Moreover, although the case where the guard member 6 was driven by the drive part 8 was demonstrated in the above-mentioned embodiment, the structure which moves a guard member manually may be sufficient.

  If this invention is utilized, it can prevent that a guard member becomes high temperature.
