Detailed Description

(insight underlying the present invention)

The present inventors have conducted intensive studies to efficiently collect water in a tray, and as a result, have obtained the following findings.

In a conventional heating cooker, a water receiving portion is provided below a joint portion of a front frame around an opening and a rear surface side of a door, and a tray is disposed below the water receiving portion. The water receiving portion is fixed to a bottom surface of the front frame extending rearward from a lower edge portion of the front frame.

However, in the conventional heating cooker, the water receiving portion is fixed to the bottom surface of the front frame, and thus the lower edge portion of the front frame is exposed. Therefore, water tends to stay at the lower edge of the front frame due to surface tension, and is less likely to fall toward the water receiving portion. Thus, the present inventors found that it is difficult to efficiently collect water in the tray.

Therefore, as a result of intensive studies, the present inventors have found the following: by providing the water receiving portion on the front surface of the front bezel so as to cover the lower edge portion of the front bezel, the flow of water to the lower edge portion of the front bezel is suppressed, and the stay of water at the lower edge portion of the front bezel can be suppressed. Thus, the present inventors have found that water can be efficiently collected in the tray.

Based on these new findings, the present inventors have obtained the following invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiment.

The water receiving portion 5 is formed on the inclined surface 61, and the water receiving portion 5 extends forward and downward from an upper portion of a front end portion 61a of the inclined surface 61. At this time, the mounting portion 63 of the guide portion 6 is formed in a step shape from the rear end 61b of the inclined surface 61 and at a position higher than the inclined surface 61.

Further, as shown in fig. 5, the mounting portion 63 has a mounting hole 63 a. Thereby, the guide portion 6 is attached to the bottom plate 35 of the body 3 through the attachment hole 63a of the attachment portion 63.

Next, a structure for discharging water flowing down the rear surface 33b of the front frame 33 to the tray 7 will be described in detail with reference to fig. 14 to 17.

As shown in fig. 14 to 17, the guide portion 6 further includes a protrusion 65a, a protrusion 65b, and a protrusion 65c protruding upward (+ Z direction) from the inclined surface 61. As shown in fig. 14, the projection 65a is provided on one end side (left side) of the guide portion 6. As shown in fig. 15, a projection 65b is provided at the center of the guide portion 6. As shown in fig. 16, a protrusion 65c is provided on the other end side (right side) of the guide portion 6. The projection 65a is inserted into the hole 332a of the lower step 331a of the bottom 331 with a gap. The projection 65b is inserted into the hole 332b of the lower step 331a with a gap. The projection 65c is inserted into the hole 332c of the lower step 331a with a gap.

At this time, as shown in fig. 14, inclined portion 51 of water receiving portion 5 is provided with 1 st drain port 513 communicating with hole 332a of bottom portion 331 of front frame 33. The 1 st drain port 513 is provided in front of the projection 65a in the inclined portion 51. Thus, water flowing down the rear surface 33b of the front frame 33 flows down through the gap between the hole 332a and the projection 65a, and is discharged from the 1 st drain port 513 to the 1 st tray 71.

As shown in fig. 15, a 2 nd drain port 515 communicating with the hole 332b in the center portion of the bottom 331 is provided between the inclined portion 51 and the lower end portion 53b of the rail 53. The 2 nd drain port 515 is provided around the projection 65 b. Thus, water flowing down the rear surface 33b of the front frame 33 flows down between the hole 332b and the projection 65b, and is discharged from the 2 nd drain port 515 to the 1 st tray 71.

As shown in fig. 15 and 16, the 2 nd tray 73 is arranged on the other end side of the 1 st tray 71 and extends to the other end side (right side) of the end portion on the other end side of the guide portion 6.

The extension portion 73a is disposed on the other end side (right side) of the 3 rd drain port 67. Accordingly, the water flowing down the rear surface 33b flows down between the hole 332c of the bottom 331 and the projection 65c of the guide portion 6, and is discharged from the 3 rd drain port 67 to the 2 nd tray 73.

As shown in fig. 17, the guide portion 6 includes a water stop 69a, and the water stop 69a is provided at a position closer to one end side (left side) than the projection 65a at the one end side (left side). The water is smoothly guided to the 1 st drain port 513 by the water stop 69 a. Further, the guide portion 6 has a water stop 69b, and the water stop 69b is provided on one end side (left side) of the projection 65c on the other end side (right side). The water is smoothly guided to the 3 rd water discharge port 67 by the water stop 69 b.

Hereinafter, a drainage path of water (dew condensation water) generated in the heating cooker 1 of the present embodiment will be described in detail. In general, in the heating cooker 1, steam supplied from a steam generator (not shown) to the heating chamber 31 and steam generated from food condense in the heating cooker 1 to become water.

At this time, as shown in fig. 7 and 9, water condensed on the rear surface (heating chamber 31 side) of the door 9 flows downward along the front surface 33 of the front frame 33 through the gap 97 between the door 9 and the front frame 33. The water condensed on the front surface 33a of the front frame 33 also flows downward along the front surface 33 a.

As shown in fig. 4, water flowing down along one end side (left side) of the front surface 33a passes through the inclined portion 51 of the water receiving portion 5 and is discharged to the 1 st tray 71. On the other hand, water flowing down along the other end side (right side) of the front surface 33a is guided from the other end side (right side) to the lower end portion 53b by the rail 53 of the water receiving portion 5, and is discharged to the 1 st tray 71.

As shown in fig. 10, the water condensed in the heating chamber 31 flows down from the lower surface 31b of the heating chamber 31 and the attachment portion 31c of the front frame 33 toward the rear surface 33b of the front frame 33. At this time, as shown in fig. 14, water flowing down along one end side (left side) of the back surface 33b passes through the stepped portion 331a of the bottom portion 331 and the hole 332a and is discharged to the 1 st drain port 513 of the inclined portion 51. As shown in fig. 15, the water flowing down the center of the rear surface 33b passes through the stepped portion 331a of the bottom 331 and the hole 332b and is discharged to the 2 nd drain port 515. Further, as shown in fig. 16, the water flowing down along the other end side (right side) of the back surface 33b is discharged to the 3 rd water discharge port 67 of the guide portion 6 through the stepped portion 331a and the hole 332c of the bottom portion 331.

The water flowing into the 1 st drain port 513 and the 2 nd drain port 515 is drained to the 1 st tray 71 and is received in the 1 st tray 71. Similarly, the water flowing into the 3 rd drain port 67 is drained to the 2 nd tray 73 and is received in the 2 nd tray 73. Thus, the user can remove the 1 st tray 71 and the 2 nd tray 73 from the main body 3 of the heating cooker 1, and easily remove the water contained in the 1 st tray 71 and the 2 nd tray 73.

[ Effect ]

According to the heating cooker 1 of the present embodiment, the following effects can be obtained.

The heating cooker 1 of the present embodiment includes a main body 3, a door 9, a water receiving portion 5, a tray 7, and the like. The main body 3 includes a heating chamber 31 and a front frame 33, and the front frame 33 is provided around an opening 31a of the heating chamber 31 and includes the opening 31 a. The door 9 covers the opening 31a so as to be openable and closable, and is attached to the main body 3. The water receiving portion 5 extends in the width direction below the opening 31a, and receives water flowing down along the front surface 33a of the front frame 33. The tray 7 is disposed below the water receiving portion 5 and receives water received by the water receiving portion 5. The tray 7 is detachably attached to the main body 3. Water receiving unit 5 is provided to cover at least a part of lower edge portion 335 of front bezel 33, and is brought into contact with front surface 33a of front bezel 33, and guides water from front surface 33a of front bezel 33 to tray 7. In addition, the tray 7 includes a 1 st tray 71 and a 2 nd tray 73.

According to this configuration, water receiving unit 5 is disposed on front surface 33a of front frame 33 so as to cover lower edge portion 335 of at least a part of front frame 33. Accordingly, water flowing to a portion where the lower edge portion 335 of the front frame 33 is not exposed passes through the water receiving portion 5 and falls into the tray 7. Therefore, it is possible to suppress the water droplets from staying at the lower edge portion 335 of the front frame 33 without falling into the tray 7 due to the surface tension.

The water receiving portion 5 of the heating cooker 1 of the present embodiment includes the rail 53, and the rail 53 is formed in a concave shape whose inner surface is inclined in the width direction. According to this configuration, water flowing down from the front surface 33a of the front frame 33 toward the tray 7 is guided in the width direction via the rail 53.

The water receiving portion 5 has an inclined portion 51 inclined obliquely downward toward the front. According to this configuration, water can be prevented from accumulating on the upper surface area of water receiving unit 5 by inclined portion 51. Therefore, water can be inhibited from entering between the water receiving portion 5 and the front surface 33a of the front frame 33.

The water receiving portion 5 includes a rail 53 and an inclined portion 51 inclined obliquely downward toward the front. The inclined portion 51 extends from one end side in the width direction to the center portion with respect to the front frame 33. The rail 53 extends from the other end side in the width direction to the center portion with respect to the front frame 33. According to this configuration, the water receiving portion 5 can constitute the guide portion of water having different paths in the range from one end side to the center portion and from the other end side to the center portion of the front frame 33. This enables water in each path to be stored in 1 tray. As a result, when a plurality of trays are provided, the degree of freedom of the shape of each tray is improved.

The rail 53 of the water receiving portion 5 is inclined downward from the other end side toward the central portion. The tray 7 has: a 1 st tray 71 having a width from an end portion on one end side in the width direction of the main body 3 to a lower end portion 53b of the rail 53; and a 2 nd tray 73 arranged side by side with the other end side of the 1 st tray 71 in the width direction. The 1 st tray 71 contains water flowing down through the inclined portion 51 and the rail 53.

With this configuration, the rail 53 is inclined in one direction. Thus, the inclination angle of the rail 53 can be increased as compared with a configuration in which the rail 53 is inclined toward the one end side and the other end side to guide water in two directions. Therefore, the water flowing down is easily guided to the central portion of the water receiving portion 5 via the rail 53. Further, the water guided by the rail 53 can be stored in the 1 st tray 71 which is the same as the tray 7 storing the water by the inclined portion 51. This allows water flowing down the front surface 33a of the front frame 33 to be collected and stored at one location, and therefore, the collected water can be easily discharged. Further, when the amount of steam in the heating chamber 31 is increased, for example, when the airtightness of the main body 3 is improved or when the amount of steam is increased, water condensed on the front frame 33 and the door 9 is increased. In this case, the structure of the tray 7 for containing the dew condensation water is more important. Therefore, in the heating cooker 1 of the present embodiment, the 1 st tray 71 and the 2 nd tray 73 are arranged, and water flowing down from the front surface 33a of the front frame 33 is accommodated in the 1 st tray 71. Therefore, even when the 2 nd tray 73 is provided with the water tank for steam generation, water condensed on other parts of the main body 3, for example, the rear part of the main body 3, can be stored in the 2 nd tray 73.

The rail 53 of the water receiving unit 5 has a cover 53a, and the cover 53a extends forward from a lower end portion 53b on one end side and covers a gap in the width direction between the 1 st tray 71 and the 2 nd tray 73. According to this structure, the cover 53a can prevent water from falling into the gap along the back surface of the door 9. Therefore, the water can be more reliably suppressed from falling out of the tray 7.

The inclined portion 51 of the water receiving portion 5 has a protruding portion 511 extending downward from the front end portion. According to this structure, the water removal effect against the retention of water in the leading end portion 51b of the inclined portion 51 due to surface tension is further improved by the protruding portion 511. As a result, water can easily flow from the front frame 33 to the tray 7.

The heating cooker 1 of the present embodiment includes a main body 3, a door 9, a tray 7, and the like. The main body 3 includes a heating chamber 31 and a front frame 33, and the front frame 33 is provided around an opening 31a of the heating chamber 31 and has the opening 31 a. The door 9 is attached to the main body 3 to openably and closably cover the opening 31 a. The tray 7 is disposed below the front frame 33 so as to be detachable from the main body 3, and accommodates water flowing down the front frame 33. The front frame 33 has a bottom 331 extending rearward from a lower end of the front frame 33. The bottom 331 has

holes

332a, 332b, and 332c for allowing water flowing down the back 33b of the front frame 33 to flow to the tray 7. The upper surface 331ba of the rear end portion of the bottom portion 331 is disposed at a position higher than the

holes

332a, 332b, and 332 c.

With this configuration, water flowing down the back surface 33b of the front frame 33 flows into the tray 7 through the

holes

332a, 332b, and 332c provided in the bottom 331. Therefore, the water can be suppressed from accumulating in the bottom 331. The upper surface 331ba of the rear end portion of the bottom portion 331 is disposed at a position higher than the

holes

332a, 332b, and 332 c. This can prevent water flowing down the rear surface 33b of the front frame 33 from flowing down the upper surface 331ba of the bottom 331 to the rear end.

The lower surface 331bb of the rear end of the bottom portion 331 is disposed higher than the

holes

332a, 332b, and 332 c. With this structure, water flowing down the front surface 33a of the front frame 33 can be suppressed from flowing down the lower surface 331bb of the bottom 331 to the rear end.

The main body 3 has a bottom plate 35 attached to the front frame 33, and the bottom plate 35 is positioned between the heating chamber 31 and the tray 7 in the height direction. The bottom 331 has: a lower step 331a extending rearward from a lower end of the front frame 33 and having

holes

332a, 332b, and 332 c; and an upper step 331b formed in a step shape from the lower step 331a and extending rearward at a position higher than the

holes

332a, 332b, and 332 c. The front frame 33 is attached to the front portion of the bottom plate 35 via an upper step portion 331 b. According to this configuration, even in a configuration without water receiving unit 5, for example, water flowing down front surface 33a of front frame 33 can be prevented from entering between front frame 33 and bottom plate 35. This can more reliably prevent the front portion 35a of the bottom plate 35 from rusting.

Further, a guide portion 6 attached to the body 3 is provided below the

holes

332a, 332b, and 332c of the bottom portion 331, and the guide portion 6 extends in the width direction and has an inclined surface 61 inclined obliquely downward toward the front. With this configuration, the water flowing down through the

holes

332a, 332b, and 332c can be guided forward by the inclined surface 61 of the guide 6. This makes it possible to effectively utilize the space below the

holes

332a, 332b, and 332c of the bottom 331.

The guide portion 6 of the water receiving portion 5 has a mounting portion 63, and the mounting portion 63 is formed in a step shape from the rear end of the inclined surface 61 and extends rearward at a position higher than the inclined surface 61. The guide portion 6 is attached to the body 3 via the attachment portion 63. According to this configuration, a space is formed between the attachment surface of the attachment portion 63 and the inclined surface 61 of the guide portion 6. This can prevent water from overflowing from the guide portion 6, and can guide more water to the front.

The guide portion 6 of the water receiving portion 5 has

projections

65a, 65b, and 65c, and the

projections

65a, 65b, and 65c project upward from the inclined surface 61 and are inserted into the

holes

332a, 332b, and 332c of the bottom portion 331 with a gap therebetween. With this configuration, water flowing down from the

holes

332a, 332b, and 332c of the bottom 331 easily flows down to the guide portion 6 through the

protrusions

65a, 65b, and 65 c. Further, the positioning between the guide portion 6 and the bottom portion 331 can be easily performed.

Furthermore, in heating cooker 1 of the present embodiment, water receiving portion 5 is provided below opening 31a, and water receiving portion 5 extends in the width direction, is formed integrally with guide portion 6, and receives water flowing down front surface 33a of front frame 33. The water receiving portion 5 is provided on the front surface 33a of the front frame 33 so as to cover at least a part of the lower edge portion 335 of the front frame 33, and guides water from the front surface 33a of the front frame 33 to the tray 7. With this configuration, water flowing down the front surface 33a of the front frame 33 can be suppressed from flowing toward the lower edge portion 335 of the front frame 33. As a result, the water can be further inhibited from flowing from the lower edge portion 335 of the front frame 33 to the rear end portion along the lower surface 331bb of the bottom 331.

The water receiving portion 5 includes an inclined portion 51 inclined obliquely downward toward the front and a rail 53 formed in a concave shape. The concave inner surface of the rail 53 is inclined toward one end side in the width direction. The inclined portion 51 extends from one end side in the width direction to the center portion at the front frame 33, and the rail 53 extends from the other end side in the width direction to the center portion at the front frame 33. According to this configuration, the water receiving portion 5 forms a guide portion for water having different paths in the range from one end side to the center portion and from the other end side to the center portion of the front frame 33. This enables water in each path to be stored in 1 tray. As a result, when a plurality of trays are provided, the degree of freedom of the shape of each tray is improved.

Further, the tray 7 has a 1 st tray 71 and a 2 nd tray 73. The 1 st tray 71 has a width from an end on one end side in the width direction of the main body 3 to the lower end 53b of the rail 53. The 2 nd tray 73 is arranged side by side with the other end side of the 1 st tray 71 in the width direction to a position closer to the other end side than the end portion of the other end side of the guide portion 6. The bottom portion 331 has

holes

332a, 332b, 332c at one end portion, a central portion, and the other end portion. Inclined portion 51 is provided with a 1 st drain port 513 communicating with hole 332a at one end. Between inclined portion 51 and lower end portion 53b of rail 53, second drain port 515 communicating with hole 332b in the center portion is provided. A 3 rd water discharge opening 67 is provided at the other end side end portion of the guide portion 6, and the 3 rd water discharge opening 67 is inclined obliquely downward toward the other end side and communicates with the hole 332c at the other end side.

According to this structure, the bottom 331 has

holes

332a, 332b, 332c at one end portion, the central portion, and the other end portion. This enables water flowing down the back surface 33b of the front frame 33 to be efficiently discharged. That is, water flowing down through the hole 332a at the one end portion can flow from the 1 st drain port 513 to the 1 st tray 71, and can be stored in the 1 st tray 71. The water flowing down through the hole 332b in the center portion can be allowed to flow from the 2 nd drain port 515 to the 1 st tray 71, and can be stored in the 1 st tray 71. Further, the water flowing down through the hole 332c at the other end can be allowed to flow from the 3 rd water discharge port 67 to the 2 nd tray 73, and can be stored in the 2 nd tray 73. Therefore, the water flowing down the rear surface 33b of the front frame 33 can be separately discharged to the 1 st tray 71 and the 2 nd tray 73, and therefore, more water can be stored.

The present invention is not limited to the above embodiments, and can be implemented in various other embodiments.

For example, in the above-described embodiment, the case where the rail 53 of the water receiving portion 5 is inclined downward from the other end side toward the center portion has been described as an example, but the present invention is not limited thereto. The water receiving portion 5 may be configured to be disposed on the front surface 33a of the front frame 33 so as to cover at least a part of the lower edge portion 335 of the front frame 33, or may be configured to be other. For example, the following structure may be adopted: the inclination of the track is formed toward the 2 directions of the one end side and the other end side, and the water is guided to the two directions. With this configuration, it is possible to prevent water droplets from falling onto the tray 7 due to surface tension and staying at the lower end of the rail at the lower edge 335 of the front frame 33.
