Description

Technical Field

[0001] The present invention relates to a heating cooker with a rice cooking function. Background Art

[0002] As a conventional heating cooker, there is known a heating cooker equipped with a steam cylinder for discharging the steam generated in the pot to the outside of the heating cooker (for example, refer to Patent Document 1). The steam cylinder is configured to connect the inside of the pot with the external fluid of the heating cooker. Therefore, the high-temperature rice soup (viscous soup) generated during the rice cooking process enters the steam cylinder. When the high-temperature rice soup is discharged to the outside of the heating cooker, it may cause burns. In addition, since the rice soup contains more delicious ingredients, the taste of the rice can be improved by returning it to the pot. Therefore, the steam cylinder has a space for storing rice soup when the pressure in the pot is high (hereinafter also referred to as a rice soup storage part), and is configured to return the rice soup to the pot when the pressure in the pot is reduced.

[0043] Figure 3 2 is a bottom view showing the structure of the inner cover 22 of the cover body 2. An annular gasket 23 is provided at a position corresponding to the flange portion 3a of the inner cover 22 of the cover body 2. Figure 2When the rice cooker 3 is in the position shown in the figure, the gap between the flange portion 3a of the pot 3 and the inner cover 22 of the cover body 2 is closed by the gasket 23. In addition, the inner cover 22 of the cover body 2 is provided with a steam inlet 22a, which sucks in the steam generated in the pot 3 when the control unit 16 executes the rice cooking process. In this embodiment, the steam inlet 22a is composed of a plurality of through holes smaller than rice grains to suppress the passage of rice grains, while allowing the passage of steam and rice soup.

[0044] Figure 4 1 is an exploded perspective view showing components of the pot 3 and the outer cover 21 of the lid body 2. The outer cover 21 includes an outer cover base 24, a steam passage forming member 25, and a steam passage cover 26 as components.

[0045] The outer cover base 24 is a component that supports the various components of the outer cover 21. The outer cover base 24 is provided with a through hole 24a that is fluidly connected to the steam inlet 22a of the inner cover 22. When the inner cover 22 is mounted on the outer cover 21, an annular gasket (not shown) is provided between the inner cover 22 and the outer cover 21 and around the steam inlet 22a of the inner cover 22 and the through hole 24a.

[0046] The outer cover base 24 is provided with a steam passage forming member 25. The steam passage forming member 25 is provided to the outer cover base 24 by a plurality of fastening members such as screws. The steam passage forming member 25 is a member for guiding the steam sucked from the through hole 24a to the steam outlet 21a provided on the upper surface of the outer cover 21. The steam outlet 21a is an opening for discharging the steam generated in the pot 3 to the outside of the heating cooker. Figure 2 In the top view of the cover body 2 (in the vertical direction), the steam outlet 21a is arranged at a position away from the steam inlet 22a. In the present embodiment, a steam passage is formed by the steam passage forming member 25, which is fluidly connected to the steam inlet 22a and the steam outlet 21a. A rice soup storage portion 27 for storing rice soup is provided in the steam passage. In the present embodiment, the rice soup storage portion 27 is formed by the steam passage forming member 25 and the steam passage cover 26.

[0047] Figure 5 It is a perspective view of the steam passage forming member 25 . Figure 6 It is a bottom view of the steam passage forming member 25 . Figure 7 It is a plan view of the steam passage forming member 25 . Figure 8 It is a top view of the steam passage cover 26. Fig. 9 yes Figure 7 A1-A1 cross-sectional view.

[0048] The rice soup reservoir 27 is a substantially box-shaped space. The bottom wall of the rice soup reservoir 27 has an inlet 27a in fluid communication with the steam inlet 22a. The inlet 27a is formed to have an opening area larger than the opening areas of the steam inlet 22a and the steam outlet 21a.

[0049] like Figure 7 As shown, the rice soup reservoir 27 has a side wall surface 27b that curves so as to move away from the steam discharge port 21a as it moves from the steam introduction port 22a to the steam discharge port 21a in a plan view.

[0050] The rice soup storage part 27 has a rear wall surface 27c, which is located downstream of the steam outlet 21a from the steam inlet 22a. The rear wall surface 27c has a protrusion 27ca that protrudes away from the steam outlet 21a. The side wall surface 27b is continuously connected to the protrusion 27ca. The protrusion 27ca has a guide surface 27cb, which is formed in a manner similar to the guide surface 27cb of the side wall surface 27b. Figure 7 As shown by the solid arrow, the guide surface 27cb is inclined or curved so that the rice soup entering the protruding portion 27ca flows toward the side wall surface 27b.

[0051] The rice soup storage part 27 has one or more step portions 27d between the steam inlet 22a and the steam outlet 21a when viewed from above. In this embodiment, the rice soup storage part 27 has one step portion 27d between the inlet 27a and the steam outlet 21a when viewed from above. The height of the step portion 27d is, for example, higher than the thickness of the bottom wall of the rice soup storage part 27.

[0052] The rice soup storage portion 27 is configured such that, in a plan view, the imaginary straight line L1 (at the center 21aa of the steam outlet 21a) extending from the steam inlet 22a toward the steam outlet 21a and passing through the center 21aa of the steam outlet 21a is Figure 7 In the present embodiment, the rice soup storage portion 27 is asymmetrical on either side (indicated by a single dotted line) of the imaginary straight line L1. Figure 7 The side wall surface 27b is located on the right side of the imaginary straight line L1.

[0053] The upper wall of the rice soup storage part 27 is formed by a steam passage cover 26. In the present embodiment, the steam passage cover 26 is configured to be removable relative to the upper opening of the steam passage forming member 25. The steam passage cover 26 has a cylindrical part 26a at a position corresponding to the steam discharge port 21a. The rice soup storage part 27 is fluidically connected to the steam discharge port 21a through the cylindrical part 26a.

[0054] The rice soup storage part 27 has Fig. 9The bottom wall surface 27e guides the rice soup as shown by the solid arrow. The bottom wall surface 27e is inclined upward from the steam introduction port 22a to the steam discharge port 21a.

[0055] According to the heating cooker of this embodiment, since the rice soup storage part 27 has the side wall surface 27b, the rice soup can be guided to leave the steam outlet 21a through the side wall surface 27b. As a result, it is possible to prevent the rice soup from being discharged to the outside of the heating cooker through the steam outlet 21a. In addition, it is possible to eliminate the need to provide ribs on the rice soup storage part 27, and the cleanability of the rice soup can be improved.

[0056] In addition, according to the heating cooker of this embodiment, since the rice soup storage part 27 has the protrusion 27ca, the rice soup can collide with the protrusion 27ca located at a position far from the steam outlet 21a, thereby suppressing the momentum of the rice soup. In addition, the side wall surface 27b is continuously connected to the protrusion 27ca, so that the volume of the space far from the steam outlet 21a can be ensured to be large. Therefore, it is possible to further suppress the rice soup from being discharged to the outside of the heating cooker through the steam outlet 21a.

[0057] In addition, according to the heating cooker of this embodiment, since the protrusion 27ca has the guide surface 27cb, the rice soup can be guided along the protrusion 27ca and the side wall surface 27b. This can further prevent the rice soup from being discharged to the outside of the heating cooker through the steam discharge port 21a. In addition, the necessity of providing ribs on the rice soup storage part 27 can be eliminated, and the cleanability can be improved.

[0058] In addition, according to the heating cooker of this embodiment, since the rice soup storage part 27 has the step part 27d, the momentum of the rice soup can be further suppressed by the collision of the rice soup with the step part 27d. Therefore, it is possible to further suppress the rice soup from being discharged to the outside of the heating cooker through the steam discharge port 21a. In addition, the necessity of providing ribs on the rice soup storage part 27 can be eliminated, and the cleaning efficiency can be improved.

[0059] In addition, according to the heating cooker of this embodiment, since the rice soup storage part 27 is configured to be asymmetrical with respect to the imaginary straight line L1, the flow of the rice soup can be biased to either the left or right side with respect to the imaginary straight line L1. Thus, for example, the flow of the rice soup along the side wall surface 27b can be intentionally controlled, and the discharge of the rice soup to the outside of the heating cooker through the steam discharge port 21a can be further suppressed. In addition, the necessity of providing ribs on the rice soup storage part 27 can be eliminated, and the cleaning efficiency can be improved.

[0060] In addition, according to the heating cooker of this embodiment, since the rice soup storage part 27 has the side wall surface 27b on either side of the imaginary straight line L1, the side wall surface 27b is not provided on any other side, and the increase in the volume of the rice soup storage part 27 can be suppressed. In addition, the side wall surface 27b and the surroundings of the protruding part 27ca are easily affected by the heat of the rice soup and become hot. By not providing the side wall surface 27b on any other side of the imaginary straight line L1, heat-sensitive components can be arranged around the other side.

[0061] In addition, according to the heating cooker of this embodiment, since the rice soup reservoir 27 has the bottom wall surface 27e, the momentum of the rice soup entering the rice soup reservoir 27 can be suppressed by gravity. In addition, the rice soup entering the rice soup reservoir 27 can be returned to the inlet portion 27a.

[0062] In addition, according to the heating cooker of this embodiment, since the opening area of ​​the inlet 27a of the rice soup storage part 27 is larger than the opening areas of the steam inlet 22a and the steam outlet 21a, the momentum of the rice soup entering the rice soup storage part 27 can be suppressed. As a result, the rice soup can be suppressed from being discharged to the outside of the heating cooker through the steam outlet 21a. In addition, the necessity of providing ribs in the rice soup storage part 27 can be eliminated, and the cleanability of the rice soup can be improved. In addition, for example, by increasing the opening area of ​​the inlet 27a so that the user's finger can enter, the user's finger can enter the rice soup storage part 27 through the inlet 27a, thereby cleaning the rice soup storage part 27. As a result, the necessity of configuring the rice soup storage part 27 to be detachable relative to the cover body 2 (outer cover 21) can be eliminated.

[0063] Furthermore, according to the heating cooker of this embodiment, by having the above-mentioned structure, the movement path of the rice soup can be shortened. As a result, the volume of the rice soup storage part 27 can be reduced by 20% to 30% compared with the conventional one.

[0064] In addition, the present disclosure is not limited to the above-mentioned embodiment, and can be implemented in various other ways. For example, in the above, the rice soup storage part 27 is configured to be asymmetric with respect to the imaginary straight line L1, but the present disclosure is not limited to this. For example, the rice soup storage part 27 can also be configured to be symmetric with respect to the imaginary straight line L1. That is, the rice soup storage part 27 can have two side wall surfaces 27b and two protrusions 27ca. In addition, the rice soup storage part 27 can also have two side wall surfaces 27b and two protrusions 27ca of different sizes.

[0065] In addition, Fig. 9 2 shows a case where the upper wall surface of the steam passage cover 26 is flat, but the present disclosure is not limited thereto. Fig.10As shown, the upper wall surface of the steam passage cover 26 may also have an upper wall surface 26b, which is inclined downward as it approaches the steam outlet 21a (cylindrical portion 26a) from the upper end of the rear wall surface 27c (for example, the protruding portion 27ca) when viewed from the side orthogonal to the thickness direction of the cover body 2. That is, the rice soup storage portion 27 may have an upper wall surface 26b that is inclined downward as it approaches the steam outlet 21a from the upper end of the rear wall surface 27c when viewed from the side. As a result, as Fig.10 As shown by the solid arrow, the flow of the rice soup that collides with the rear wall surface 27c (for example, the protruding portion 27ca) and moves in the opposite direction can be directed downward. As a result, the rice soup can be further prevented from being discharged to the outside of the heating cooker through the steam outlet 21a. In addition, the necessity of providing ribs on the rice soup storage portion 27 can be eliminated, and the cleanability can be improved.

[0066] In addition, by appropriately combining any of the various embodiments described above, the effects possessed by each can be achieved.

[0067] The present disclosure is fully described with appropriate reference to the drawings and in association with the preferred embodiments, but various deformations and modifications are obvious to those skilled in the art. It should be understood that such deformations and modifications are included therein without departing from the scope of the present disclosure according to the attached technical solutions.
