The imaging unit 150 includes a shutter that is rotated by a drive motor to protect the camera 154 from steam or scattered objects from the object to be heated.
By providing the imaging unit 150 on the ceiling, which is the upper wall of the heating box 110, the imaging unit 150 can image an image at an angle and position where the heating box 110 is viewed downward. This makes it possible to photograph the upper side of the object with higher accuracy, i.e., with high resolution and less keystone distortion.
The configuration in which the image is taken from the upper wall of heating box 110 is particularly effective in applications such as recognition of characters, marks, and the like on the upper surface of the object to be heated with high accuracy, recognition of the type of material of the object to be heated, recognition of the shape or size of the object to be heated, and recognition of the heating state of the object to be heated.
According to the heating cooker 1 of the present invention, the convenience of the user can be improved in business use such as convenience stores or home use.
The imaging unit 150 is provided on the front side of the upper wall 111a of the heating box 110. The imaging unit 150 is provided such that the imaging plane of the camera 154 is inclined with respect to the horizontal plane such that the imaging direction is directed toward the center of the bottom wall 111e of the heating box 110. That is, the imaging unit 150 is provided such that the optical axis 157, which is the imaging direction of the camera 154, is inclined rearward with respect to the vertical direction of the heating box 110. This makes it possible to arrange the imaging unit 150 in a narrow space, avoiding the vicinity of the center in a plan view of the radiation opening 108 or the like in which microwaves, which are an example of a heating unit, are arranged. Further, the center direction in the heating box 110 can be accurately imaged while avoiding the vicinity of the center.
Further, the imaging unit 150 is provided so that the imaging direction is inclined toward the rear side with respect to the vertical direction, and thereby, the influence of the external light incident from the glass window 122 of the door 120 on the imaging can be suppressed. That is, it is possible to prevent external light incident from the glass window 122 from being directly or indirectly reflected at high luminance on an image captured by the camera 154 and degrading the imaging accuracy.
The blowing section 160 has a fan housing, a fan, and an exhaust port.
A fan is provided inside the fan housing. The fan housing has an exhaust port for blowing air. The fan is driven by a DC motor and generates an air flow toward the image pickup unit 150. The fan is driven in accordance with an instruction from the control unit 105.
Illumination portions for illuminating the inside of the heating box 110 are provided above and on the sides of the box.
The illumination unit includes an upper illumination 170a, a left illumination 170b, and a right illumination 170c.
Further, by using the LED as the light source of the illumination section, it is possible to supply a larger amount of light into the heating box 110 with high reliability.
[ Structure of the Main portion ]
The bottom wall 111e, the camera 154, and the periphery thereof will be described in detail with reference to fig. 10 to 12.
Fig. 10 is a plan view of the bottom wall 111e in the heating box 110.
The bottom wall 111e is provided with a guide mark 182 indicating a position where the object 200 is placed. The guide mark portion 182 is formed of a mark for guiding or indicating a position where the user places the object to be heated. In this embodiment, 4 guide mark portions 182 of the bracket type are provided, and the center point 181 of the guide mark portion is provided near the center thereof. The user is guided to place the object 200 in the guide region 180 surrounded by the guide mark 182.
The 7 dashed lines in fig. 10 are illustrated. The broken line T indicates the extent of the guide area 180 in the left direction (-X direction) of the bottom wall. The broken line V indicates the range of the guide area 180 in the right direction (X direction) of the bottom wall. The broken line U indicates a line crossing in the Y direction on the center point 181 of the guide mark portion. In this embodiment, the broken line U is also a line that bisects the bottom wall 111e in the heating box 110 in the left-right direction (X to-X direction).
The broken line R indicates the range of the guide region 180 in the rear direction (Y direction) of the bottom wall 111e. The broken line P indicates the range of the guide area 180 in the front direction (-Y direction) of the bottom wall 111e. The broken line Q indicates a line crossing the center point 181 of the guide mark portion in the X direction. The broken line S indicates a line that bisects the bottom wall 111e in the heating box 110 in the front-rear direction (Y to-Y direction). Therefore, the broken line Q is located on the front side (Y direction side) of the broken line S, and the center point 181 of the guide mark portion is located on the front side of the broken line S bisecting the bottom wall 111e in the heating box 110 in the front-rear direction (Y to-Y direction).
Fig. 11 is a schematic diagram showing the relationship of the imaging direction of the imaging unit 150 from the side.
As described above, the imaging unit 150 is provided on the front side of the upper wall 111a of the heating box 110. Further, the imaging section 150 is provided such that the imaging plane of the camera 154 is inclined with respect to the horizontal plane such that the imaging direction is directed toward the center of the bottom wall 111e of the heating box 110. That is, the imaging unit 150 is provided such that the optical axis 157, which is the imaging direction of the camera 154, is inclined toward the rear side with respect to the vertical direction of the heating box 110.
For example, the width (Y direction) of the bottom wall 111e is about 310mm, and the height from the bottom wall 111e to the top plate portion 140 is about 180mm, but the invention is not limited thereto.
In fig. 11, as in fig. 10, a broken line R indicates the range of the guide region 180 in the rear direction (Y direction) of the bottom wall 111e. The broken line P indicates the range of the guide region 180 in the front direction (-Y direction) of the bottom wall 111e. The broken line Q indicates a line crossing the center point 181 of the guide mark portion in the X direction. The broken line S indicates a line that bisects the bottom wall 111e in the heating box 110 in the front-rear direction (Y to-Y direction). Therefore, the broken line Q is located on the front side (-Y side) of the broken line S, and the center point 181 of the guide mark portion is located on the front side of the broken line S bisecting the bottom wall 111e in the heating box 110 in the front-rear direction (Y to-Y direction).
The camera 154 is installed at the front center of the upper wall 111a of the heating compartment 110. Specifically, the camera 154 is preferably attached to the upper wall 111a at a position above the broken line U in fig. 10 and forward (in the (-Y direction) of the broken line S.
T is an intersection of the optical axis 157 and the bottom wall 111e, which is the imaging direction of the camera 154. The broken line Q is located anterior (Y side) to the intersection T, and the center point 181 of the guide mark portion is located anterior (Y side) to the intersection T.
By providing the imaging unit 150 on the ceiling side, which is a wall above the heating box 110, the imaging unit 150 can image an image at an angle and position where the heating box 110 is viewed downward. This makes it possible to photograph the upper side of the object with higher accuracy, i.e., with high resolution and less keystone distortion.
The user places the object 200 on the bottom wall 111e in the heating box 110 with the guide mark 182 or the center point 181 of the guide mark as a mark.
Thus, the guide mark 182 is provided at a position where the user can easily place the object 200 and the user cannot easily see the object because the object is not easily dead in an oblique upward view, that is, a position forward of the center in the heating box 110, and the object 200 can be imaged by the camera 154. This allows the user to accurately and easily place the object 200 on the guide mark 182.
The configuration in which the image is taken from the upper wall of heating box 110 in this way is particularly effective for use in recognizing characters, marks, and the like on object 200 to be heated with high accuracy.
Further, it is preferable that one of the magnetron 106 and the stirrer 109 is disposed at a position (Y direction side) on the rear side of the position where the camera 154 is disposed in the heating box 110 in a plan view.
Therefore, one of the magnetron 106 and the stirrer 109 can be surely arranged at the rear side of the camera 154. As a result, adverse effects such as radio waves and noise from the microwaves to the camera 154 are reduced.
Fig. 12 is a schematic diagram illustrating a relationship of the angle of view of the imaging section 150 from the side.
As shown in fig. 12, the imaging unit 150 is provided such that the optical axis 157 is inclined toward the rear side with respect to the vertical direction of the heating box 110.
The imaging unit 150 faces the inside of the heating box 110 through the wall surface opening 112 provided in the upper wall 111a and further through the ceiling opening 141 provided in the ceiling portion 140.
As shown in fig. 12, the field of view range 158 indicates a range imaged by the imaging unit 150. The other structure is the same as that of fig. 11.
Further, a line N orthogonal to the optical axis 157 is on the same plane as the plane of the camera 154 facing the inside of the heating box 110. Here, an angle formed by a line N orthogonal to the optical axis 157 and the upper wall 111a is about 68 degrees on the acute angle side and about 112 degrees on the obtuse angle side. The front-rear direction field angle in the field of view range 158 is about 60 degrees around the optical axis.
In addition, the camera 154 is provided approximately 42mm behind the end of the front opening 102, for example. In addition, as an example, the height from the bottom wall 111e to the top plate portion 140 is about 180mm, the distance from the front opening 102 to the back wall 111d is about 310mm, and the height from the bottom wall 111e to the camera 154 is about 240mm, but the invention is not limited thereto.
Let T be the imaging direction of the camera 154, i.e., the intersection of the optical axis 157 and the bottom wall 111e. The broken line Q is located on the front side (-Y side) of the intersection T, and the center point 181 of the guide mark portion is located on the front side (-Y side) of the intersection T, so that the imaging unit 150 can image a wide range in the heating box 110. Further, the imaging unit 150 can also image the object 200 placed in the heating box 110 and having a higher height.
By providing top plate opening 141 in top plate 140, imaging unit 150 can image object to be heated 200 placed in heating box 110.
The front end of the ceiling opening 141 is positioned such that a straight line passing through the front end of the ceiling opening 141 with the position of the camera 154 of the imaging unit 150 as a base point intersects the surface of the bottom wall 111e of the heating box 110.
That is, the front end of the field of view range 158 of the camera 154 is formed so as not to intersect the front opening 102.
As shown in fig. 11 and 12, the center of the top plate opening 141 in the front-rear direction is located behind the center of the imaging unit 150 in plan view.
Accordingly, even in a configuration in which the imaging unit 150 is disposed so as to be inclined toward the rear of the heating box 110, the field of view 158 can be enlarged while suppressing incidence of external light from the front opening 102.
That is, imaging unit 150 can image object to be heated 200 placed in a wide range in heating box 110.
However, by providing top plate opening 141 in top plate portion 140, there is a possibility that a user of heating cooker 1 may touch stirrer 109 disposed at an upper portion in heating box 110.
In the present invention, a radome 145 is provided to cover the stirrer 109 from below. As shown in fig. 11 and 12, the ceiling opening 141, the imaging surface of the imaging unit 150, and a part of the antenna cover 145 are disposed so as to overlap each other in the vertical transmission viewpoint.
This prevents the user of the heating cooker 1 from touching the stirrer 109.
However, if the antenna cover 145 is provided below the upper wall 111a of the heating box 110 so as to cover the agitator 109, the field of view 158 of the imaging section 150 also provided on the upper wall 111a of the heating box 110 is caused to narrow.
In the present invention, as shown in fig. 11 and 12, a slope 145a is provided on the front side of the antenna cover 145, that is, on the imaging unit 150 side.
The slope 145a is provided on the front side of the radome 145 along the rear side angle of the field of view range 158.
Therefore, the rear end of the field of view range 158 of the video camera 154 may be a straight line passing through the end portion of the rear side of the ceiling opening 141 with the position of the camera 154 of the photographing unit 150 as a base point, without being disturbed by the radome 145.
That is, the rear end of the ceiling opening 141 is positioned such that a straight line passing through the rear end of the ceiling opening 141 with the position of the camera 154 of the imaging unit 150 as a base point intersects the surface of the rear wall 111d of the heating box 110.
Thereby, the image pickup unit 150 can pick up an image of a wide range in the heating box 110. Further, the imaging unit 150 can also image the object 200 placed in the heating box 110 and having a higher height.
Thus, in the present invention, it is possible to photograph a wide range within the heating cabinet 110 while suppressing incidence of light from outside. This enables the subject 200 to be imaged at various heights. In addition, the object 200 to be heated placed at various positions on the bottom surface of heating box 110 can be imaged.
A stirrer 109 as a rotary antenna for stirring microwaves is provided at the center of the top wall 111a of the heating box 110 in plan view.
The stirrer 109 is provided below the upper wall 111a, i.e., inside the heating box 110, to stir the microwaves of the heating box 110.
Further, an antenna cover 145 is provided on the surface of the upper wall 111a on the side of the heating box 110 so as to cover the rotation range of the agitator 109 from below. The antenna cover 145 is provided below the imaging unit 150 and above the top plate 140.
The radome 145 is formed of a polypropylene material.
Accordingly, the antenna cover 145 can be disposed in contact with the wall surface of the heating box 110 having a high temperature, and can transmit the microwaves radiated into the heating box 110.
The antenna cover 145 is formed in a bottomed bowl shape tapered downward, and has an upper opening. The radome 145 is installed such that the open end of the upper portion thereof contacts the upper wall 111 a.
An inclined surface 145a inclined with respect to the vertical direction of the heating box 110 is provided on the front side of the antenna cover 145.
The lower side of the inclined surface 145a is inclined toward the rear side of the heating compartment 110.
As shown in fig. 11 and 12, a flat-plate-shaped top plate portion 140 is provided below the upper wall 111a so as to be parallel to the upper wall 111a with a gap provided between the top wall 111a and the top wall.
Further, the top plate portion 140 is disposed below the radome 145.
The top plate 140 is formed of a flat plate as a main surface and a peripheral edge thereof. The flat plate serving as the main surface of the top plate 140 is formed of a laminate plate made of glass cloth and silicone. This allows light to be diffused and transmitted softly, and allows microwaves to be transmitted. The peripheral edge portion of the flat plate of the top plate portion 140 is formed of a polypropylene material. Thus, the top plate 140 can be disposed in contact with the wall surface of the heating box 110 having a high temperature, and can transmit the microwaves radiated into the heating box 110.
Therefore, the top plate 140 transmits the microwaves radiated into the heating box 110.
Since the flat plate portion of the top plate portion 140 is formed of a translucent material having a light guiding property in the plane direction, light with high luminance can be diffused, and surface illumination can be performed softly.
A top plate opening 141 is provided as an opening on the front side of the top plate 140.
Since the ceiling portion 140 is provided with the ceiling opening 141, the imaging portion 150 disposed on the upper wall 111a of the heating box 110 can image the inside of the heating box 110.
However, when the ceiling portion 140 is provided with the ceiling opening 141 for imaging the inside of the heating box 110, there is a possibility that the user of the heating cooker 1 touches the stirrer 109 disposed on the upper wall 111a through the ceiling opening 141.
To prevent this, a radome 145 is provided between the stirrer 109 and the top plate 140.
As shown in fig. 11, the antenna cover 145 is positioned in the opening of the ceiling opening 141 in a plan view.
By disposing the antenna cover 145 in this manner, the user of the heating cooker 1 can be prevented from touching the container 109.
Comparative example
Fig. 13 is a side explanatory view for comparison with the structure of one embodiment of the present invention.
In fig. 13, a broken line R indicates the range of the guide region 180 in the rear direction (Y direction) of the bottom wall 111e. The broken line P indicates the range of the guide area 180 in the front direction (-Y direction) of the bottom wall 111e. The broken line Q indicates a line crossing the center point 181 of the guide mark portion in the X direction. The broken line S indicates a line that bisects the bottom wall 111e in the heating box 110 in the front-rear direction (Y to-Y direction). Therefore, the broken line Q is located on the rear side (-Y side) of the broken line S, and the center point 181 of the guide mark portion is located on the rear side of the broken line S that bisects the bottom wall 111e in the heating box 110 in the front-rear direction (Y to-Y direction).
In this case, when the height of the object 200 is considerably high, the portion 190 that does not enter the visual field range 158 is generated. Thus, in the case where a character or the like to be read exists in the portion 190, it is difficult to read the character with a camera.
Fig. 14 is a side explanatory view for comparison with the structure of one embodiment of the present invention.
In fig. 14, a broken line R indicates the range of the guide region 180 in the rear direction (Y direction) of the bottom wall 111e. The broken line P indicates the range of the guide area 180 in the front direction (-Y direction) of the bottom wall 111e. The broken line Q indicates a line crossing the center point 181 of the guide mark portion in the X direction. The broken line S represents a line bisecting the bottom wall 111e in the heating box 110 in the front-rear direction (Y to-Y direction). Therefore, the broken line Q is located on the rear side (-Y side) of the broken line S, and the center point 181 of the guide mark portion is located on the rear side of the broken line S that bisects the bottom wall 111e in the heating box 110 in the front-rear direction (Y to-Y direction).
In such a case, when the width of the object 200 is considerably wide (in this case, wide in the front-rear direction), although the object enters the visual field range 158, a portion 190 that is difficult to read occurs if the image is captured with keystone distortion because the object is far from the camera 154. In the case where a character or the like to be read exists in the portion 190, it is sometimes difficult to correctly read the character with a camera.
The present invention has an effect of minimizing the difficulty in reading compared to these comparative examples.
Even if the object 200 is placed slightly off the guide mark 182, the object can be recognized as long as the object enters the field of view of the camera 154. However, the recognition accuracy is higher as the distance from the optical axis of the field of view range 158 is shorter, the distance from the camera is shorter to a certain extent, and the recognition accuracy is lower as the distance from the optical axis of the field of view range 158 is longer (closer to the end of the field of view range 158) and the distance from the camera is longer by a certain distance. That is, in the case of recognizing a character, a symbol, or the like attached to or described on the upper surface of the object 200 with high accuracy, the recognition accuracy is slightly lowered as the distance from the end of the visual field range is increased.

In the above embodiment, the configuration in which the upper illumination 170a is provided on the upper side of the upper wall 111a of the heating compartment 110 is shown. However, the upper illumination 170a may be arranged above the top plate 140 and configured to illuminate toward the top plate 140.
In the above embodiment, the top plate portion 140 is formed as a flat plate as a main surface by a laminated plate made of glass cloth and silicone. However, the translucent material may be any material that allows light to be diffused and transmitted softly.
The main surface of the top plate 140 is formed of a flat plate. However, the main surface may be formed of a curved surface or a plurality of flat surfaces.
In the above embodiment, the radome 145 is formed of a polypropylene material. However, the antenna cover 145 may be a flame-retardant material that transmits microwaves.
In the above embodiment, the antenna cover 145 is formed in a circular shape in a plan view. However, the antenna cover 145 may be provided so as to be exposed below the upper wall of the heating box 110, and may have a shape covering the stirrer 109 or the heating portion.
The present invention can be applied to a heating cooker in which an image is taken by an image pickup unit.
