Embodiment 1 FIG.
In the first embodiment, a case where the heating cooker is the rice cooker 100 will be described as an example. FIG. 1 is a perspective view showing an overall configuration of rice cooker 100 according to Embodiment 1 of the present invention. FIG. 2 is a perspective view showing a schematic internal configuration of the rice cooker 100. FIG. 3 is a perspective view of the rice cooker 100 with the upper lid 12 opened. Based on FIGS. 1-3, the structure of the rice cooker 100 is demonstrated. This rice cooker 100 cooks a to-be-heated object by heating the inner pot 21 containing the to-be-heated object (rice, water, etc.) with heating means (not shown) such as an induction heating coil. 20 is collected. In addition, in the following drawings including FIG. 1, the relationship of the size of each component may be different from the actual one.

  The rice cooker 100 houses and supports an inner pot 21 in which an object to be cooked is placed, heating means (not shown) such as an induction heating coil for heating the inner pot 21, the inner pot 21 and the heating means. A lower housing 11 to be opened, an upper lid (upper housing) 12 attached to the lower housing 11 so as to be openable and closable via a hinge portion 14 provided at an upper rear portion of the lower housing 11, and an upper lid 12 The inner lid 13 that closes the upper opening of the inner pot 21 during cooking and a predetermined amount of water are stored, and a water tank 20 that collects steam by cooling and condensing steam with the water. The inner pot 21 (specifically, the steam discharge hole 15 formed in the inner lid 13) and the water tank 20 (specifically, the water tank opening 20a provided on the upper surface of the water tank 20) are communicated with each other and stored in the inner pot 21. Steam that guides steam generated from the object to be heated into the water tank 20 The tube 30, in being configured. The lower housing 11 and the upper lid 12 constitute the main body 10.

  The lower housing 11 accommodates and supports the water tank 20 in addition to the inner pot 21 and the heating means. In FIG. 2, the case where the water tank 20 is arrange | positioned at the front (front) side of the lower housing | casing 11 is shown as an example so that a user may attach or detach easily. In addition, when the inner pot 21 is closed, such as during cooking, the upper lid 12 and the lower housing 11 are locked, and the upward movement of the upper lid 12 is restricted. A part of the upper lid 12 and a part of the lower housing 11 are locked, so that the upper lid 12 and the lower housing 11 are locked. In order to unlock the upper lid 12 and the lower housing 11, the lock release button 18 provided on the front (front) side of the upper lid 12 is pushed in, and the engagement between the upper lid 12 and the lower housing 11 is performed. Release the stop.

  Furthermore, the surface of the upper lid 12 is composed of LEDs (light-emitting diodes) that display various information such as setting conditions and operation states, liquid crystal displays, fluorescent tubes, electroluminescence, plasma displays, and the like. The display unit 16 and various operation switches such as a rice cooking switch and a reservation switch are provided, and an operation unit 17 that receives various input operations from the user is provided. In consideration of the convenience of the user, it is desirable that the display unit 16 and the operation unit 17 are installed on the front (front) side surface of the upper lid 12 as illustrated. 1 shows an example in which the display unit 16 and the operation unit 17 are provided separately, but the display unit 16 and the operation unit 17 may be provided as operation display units.

  The inner lid 13 is formed with a steam discharge hole 15 for discharging steam generated when the object to be heated stored in the inner pot 21 is heated by the heating means and cooked to the outside of the inner pot 21. ing. The shape and the number of the steam discharge holes 15 are not particularly limited, and any steam can be used as long as the steam can pass therethrough. The inner lid 13 is provided with a lid sensor 19 for detecting the initial water temperature and boiling of the object to be heated during cooking. The lid sensor 19 is not particularly limited as long as it can measure the temperature of the object to be heated accommodated in the inner pot. The hinge portion 14 connects the upper lid 12 and the lower housing 11 on the rear (back) side, and serves as a fulcrum so that the upper lid 12 can be moved to the front side.

  The water tank 20 can store a predetermined amount of water therein, and one end of the water tank steam conduit 20 b that communicates with the water tank opening 20 a provided on the upper surface of the water tank 20 is open in the water tank 20. It is configured to be submerged in water. The steam guided from the water tank opening 20a into the water tank 20 is discharged into the water stored in the water tank 20 through the water tank steam conduit 20b, and the steam is cooled and condensed by the water. Is done. In addition, although the case where the water tank 20 is accommodated in the front side of the lower housing | casing 11 is shown as an example here, it is not limited to this. The steam conduit 30 is open at both ends, one end communicates with the steam discharge hole 15 formed in the inner lid 13, and the other end communicates with a water tank opening 20 a provided on the upper surface of the water tank 20. The steam generated in 21 is conducted to the water tank 20. The steam conduit 30 also has a function of separating and recovering a viscous fluid (hereinafter referred to as a rice ball) containing components such as rice starch contained in the steam from the steam.

  That is, the steam conduit 30 separates the steam generated at the time of rice cooking from the rice pad that conducts along with the steam, and guides only the steam to the water tank 20. If the inclination is provided in the steam conduit 30 so that the inner pot 21 side is lowered, the collected rice bowl can be returned to the inner pot 21. In this case, the larger the volume inside the steam conduit 30, the more it can be recovered.

  In addition, a display unit 16 and an operation unit 17 are installed on the top surface of the upper lid 12 that is easily accessible by the user. The interior of the upper lid 12 is vulnerable to a steam conduit 30 that is heated by steam and a temperature rise. The display unit 16 and the operation unit 17 are arranged. Therefore, as shown in FIG. 2, the steam conduit 30 is arranged at a position that does not overlap the installation position of the display unit 16 and the operation unit 17 when viewed from the top surface side of the upper lid 12 (a position that does not overlap in the vertical direction). (It will be described in detail with reference to FIGS. 3 and 4). Thereby, the heat of the steam conduit 30 is not easily transmitted to the display unit 16 and the operation unit 17, so that it is possible to prevent the display unit 16 and the operation unit 17 from rising in temperature and failing due to the heat of the steam conduit 30.

Further, since the temperature of the inner lid 13 rises by using the heat in the inner pot 21 and the heat retaining heater 13 a provided in the inner lid 13, the display unit 16 and the operation unit 17 are located away from the inner pot 13. It is good to provide in. In particular, the water tank 20 is a part where the temperature rise is small in the rice cooker 100, and is located in the lower casing 11 along with the inner pot 21, so that it is away from the inner lid 13 installed at a position facing the inner pot 21. Therefore, by arranging the display unit 16 and the operation unit 17 at a position where at least a part thereof overlaps the water tank 20 when viewed from the top surface side of the upper lid 12, the temperature rise can be suppressed.
Furthermore, by providing a heat insulating material (not shown) between the steam conduit 30 and the display unit 16 and the operation unit 17, it is possible to further suppress the temperature rise of the display unit 16 and the operation unit 17.

  FIG. 4 is a perspective view showing a state where the upper lid 12 is removed from the lower housing 11. The upper lid 12 will be described in detail based on FIG. FIG. 4 shows a state in which the upper lid 12 with the inner lid 13 attached is viewed from the bottom surface side (lower housing 11 side). The upper lid 12 may be detachable from the lower housing 11 or may be fixed by a hinge portion 14. A concave portion is formed on the bottom surface side (lower housing 11 side) of the upper lid 12, and the inner lid 13 and the steam conduit 30 are detachably attached thereto. In FIG. 4, the display unit 16 and the operation unit 17 are omitted.

  As shown in FIGS. 1 to 4, the top surface of the upper lid 12 (the surface on which the display unit 16 and the operation unit 17 are formed) has no exhaust hole for discharging steam and has a flat shape. This is because the steam conduit 30 is mounted inside the upper lid 12 and the steam is collected in the water tank 20. That is, since the steam exhaust hole can be configured without being provided in the upper lid 12, the appearance of the upper lid 12 can be made clear with less unevenness. Therefore, the cleaning property of the upper lid 12 is enhanced, and at the same time, the top surface of the upper lid 12 is not changed in color by being exposed to high temperature steam.

  By doing so, the degree of freedom of the material and paint color of the upper lid 12 is increased, and in addition to the design by shape, the design by color can be improved, and the rice cooker 100 that can meet user needs is provided. can do. For example, it is possible to freely select a color that matches the color of furniture, kitchen, etc., and to configure the main body 10 with that color. Further, since the steam conduit 30 is configured to be detachable from the upper lid 12, only the steam conduit 30 can be detached, carried and washed at the time of cleaning, and the labor required for cleaning can be reduced.

  Further, the steam conduit 30 has a shape that avoids the display unit 16 and the operation unit 17 installed on the front side of the upper lid 12, for example, the steam conduit 30 has a substantially L shape. That is, the steam conduit 30 is formed so as to extend from the central portion of the inner lid 13 toward the side surface of the upper lid 12, and is bent at a substantially right angle from this portion so that the inner side surface of the upper lid 12 is connected to the upper end of the water tank 20. The planar shape is substantially L-shaped with the part extending along the part. By adopting such a shape, the steam conduit 30 can be mounted at a position that does not overlap with the installation position of the display unit 16 and the operation unit 17. That is, the steam conduit 30 is mounted at a position that does not overlap the display unit 16 and the operation unit 17 when the rice cooker 100 is seen through from above.

  FIG. 5 is a plan view for explaining an example of the steam conduit. Based on FIG. 5, the structure and function of the steam conduit 30 which is an example of the steam conduit will be described in detail. As shown in FIG. 5, the steam conduit 30 has a substantially L shape. By setting it as such a shape, the display part 16 and the operation part 17 which are installed in the front side of the upper cover 12 can be avoided. As described above, it is desirable that the volume inside the steam conduit 30 is large, but the installation space is limited. Therefore, by making the steam conduit 30 substantially L-shaped, the inside of the upper lid 12 is secured while ensuring a predetermined volume. Can be used effectively.

  The steam conduit 30 is formed to be bent so as to be substantially L-shaped. By carrying out like this, this corner | angular part can be used as a weir with respect to the rice bowl which blows out with an internal pan from a steam. If the rice cake is connected to the steam conduit 30 along with the steam and flows into the water tank 20, the inside of the water tank 20 becomes dirty. If the inside of the water tank 20 becomes dirty and the state is left unattended, germs and the like will propagate and the hygiene will deteriorate. Therefore, the steam conduit 30 is bent at a predetermined angle in the traveling direction (horizontal direction) of the rice bowl so as to obtain a weir that is extremely effective against the penetration of the rice bowl.

  Moreover, the internal space of the upper cover 12 can be effectively utilized by making the steam conduit 30 into a substantially L shape. That is, since the steam conduit 30 can be mounted and supported in an internal space where the upper lid 12 is not used, the internal space of the upper lid 12 can be effectively utilized. Therefore, it can arrange | position so that the installation position of the vapor | steam conduit | pipe 30 and the installation position of the display part 16 and the operation part 17 may not overlap, the installation space of the display part 16 and the operation part 17 can be expanded, and a user Convenience is greatly improved. That is, an operation panel or the like for large characters can be arranged, and the usable user layer can be expanded.

  The steam conduit 30 may be assembled. In this case, a seal member or the like may be provided at the connection portion. This is because even if the steam conduit 30 can be assembled, the sealing degree of the steam conduit 30 can be increased. If the steam conduit 30 can be assembled, the inside of the steam conduit 30 can be easily exposed, and the inside of the conduit can be cleaned with, for example, a user's bare hands without using a dedicated cleaning tool. As a result, cleanability is greatly improved. Further, the steam conduit 30 is arranged on the upper portion of the inner lid 13 and is configured to be sandwiched between the upper lid 12 and the inner lid 13. Therefore, at the time of cleaning, only the steam conduit 30 can be removed, carried and washed, and the labor required for cleaning can be reduced.

  For example, seal members may be provided at both ends of the steam conduit 30. If it does in this way, the vapor | steam conduit | pipe 30 can be comprised easily from the inner cover 13 and the water tank 20 so that attachment or detachment is possible via a sealing member. When providing seal members at both ends of the steam conduit 30, the seal members may be attached in advance to the steam conduit 30 side, or attached in advance to the connecting portion on the inner lid 13 side and the connecting portion on the water tank 20 side. May be. Alternatively, the vapor conduit 30 may be attached to the inner lid 13 in advance and configured integrally (non-separated). In this way, forgetting to attach the inner lid 13 and the steam conduit 30 can be effectively prevented.

  Furthermore, it is preferable to provide a protrusion or the like having a predetermined height on the inner bottom surface of the steam conduit 30. As described above, the steam conduit 30 is configured to form a weir with respect to a planar shape having a substantially L shape. In addition to this, by forming a protrusion in the roughly flow path of the steam conduit 30, it is possible to exert a function as a further weir against the twist. In this way, the steam conduit 30 has a very high weir effect with respect to the intrusion of rice balls. For example, the protrusion may be formed closer to the inner lid 13 than the middle portion of the steam flow path in the steam conduit 30.

  Further, the bottom surface of the steam conduit 30 may be inclined so as to rise toward the protrusion formed inside. If it does in this way, it can be made to incline so that the bottom face of the vapor | steam conduit | pipe 30 may incline in a different direction, ie, it may descend toward both ends, using a projection part etc. as a boundary. As described above, the steam conduit 30 has a substantially L-shaped weir for the beak, and functions as a weir for the beak by forming a protrusion or tilting the bottom surface. Can be effectively exhibited. Further, if the bottom surface of the steam conduit 30 is inclined, the rice bowl can be returned to the inner pot side, and moisture condensed in the steam conduit 30 can be guided to the water tank 20. Accordingly, the tub 20 does not flow into the water tank 20 and the hygienic properties of the water tank 20 can be maintained.

Embodiment 2. FIG.
FIG. 6 is a transparent perspective view showing a schematic internal configuration of rice cooker 200 according to Embodiment 2 of the present invention. Based on FIG. 6, the structure of the rice cooker 200 is demonstrated. This rice cooker 200 cooks an object to be heated by heating the inner pot containing the object to be heated by a heating means such as an induction heating coil in the same manner as the rice cooker 100 according to the first embodiment. Steam is condensed and recovered in the water tank. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and differences from the first embodiment will be mainly described.

  As shown in FIG. 6, the rice cooker 200 is different in the shape of the steam conduit 30a from the shape of the steam conduit 30 described in the first embodiment. Other configurations are the same as those of the rice cooker 100 according to the first embodiment. The steam conduit 30a is open at both ends, one end communicates with the steam discharge hole 15 formed in the inner lid 13, and the other end communicates with the water tank 20, so that the steam generated in the inner pot is conducted to the water tank 20. It is something to be made. The steam conduit 30a has a function of separating and collecting the rice cake contained in the steam, similar to the steam conduit 30 described in the first embodiment. That is, the steam conduit 30a separates the steam generated during rice cooking from the rice bowl that is conducted with the steam, and guides only the steam to the water tank 20.

  In order to return the collected rice bowl to the inner pot, it is desirable that the volume inside the steam conduit 30a is larger. A display unit 16 and an operation unit 17 are installed on the surface of the upper lid 12, and the internal space of the upper lid 12 is limited. Therefore, in the first embodiment, the case where the steam conduit 30 is substantially L-shaped and the internal space of the upper lid 12 is effectively used has been described as an example. However, in the second embodiment, the steam is further increased to ensure the volume. The internal flow path is enlarged at a portion where the conduit 30 a does not overlap with the installation position of the display unit 16 and the operation unit 17.

  That is, the steam conduit 30a communicates with the portion extended so that the flow passage cross-sectional area gradually increases from the connecting portion with the inner lid 13 toward the side surface of the upper lid 12, and the upper lid 12 It is comprised by the part extended by the fixed flow-path cross-sectional area so that the inner side surface may be along the upper one end part (connection part with the water tank 20) of the water tank 20. As shown in FIG. By adopting such a shape, the vapor conduit 30a can be mounted at a position that does not overlap the display unit 16 and the operation unit 17 when viewed from the top surface of the upper lid 12, and the display unit 16 and the operation unit 17 are provided. The space of other parts can be effectively used to increase the volume.

  FIG. 7 is a plan view for explaining another example of the steam conduit. Based on FIG. 7, the structure and function of the steam conduit 30a, which is another example of the steam conduit, will be described in detail. As shown in FIG. 7, the steam conduit 30 a includes a part where the flow path cross-sectional area gradually increases and a part where the flow path cross-sectional area is constant. By setting it as such a shape, the display part 16 and the operation part 17 which are installed in the front side of the upper cover 12 can be avoided. As described above, it is desirable that the internal volume of the steam conduit 30a is large, but the installation space is limited. Therefore, the steam cover 30a is configured in such a shape, so that a predetermined volume is secured and the upper lid 12 is secured. The internal space can be used effectively.

  In the steam conduit 30a, an angle forming portion from a portion where the flow passage cross-sectional area gradually increases to a portion where the flow passage cross-sectional area is constant can be used as a weir against the rice bowl that is blown out together with the steam from the inner pot. Further, like the steam conduit 30, a protrusion or the like is formed inside, or an inclination is provided on the bottom surface, whereby it is possible to obtain a weir that is extremely effective for entering a rice ball. The steam conduit 30 a may be assembled in the same manner as the steam conduit 30. Moreover, it is good to provide a sealing member etc. in the both ends of the vapor | steam conduit | pipe 30a.

The shape of the steam conduit is not limited to the shape described in the first embodiment or the second embodiment. That is, the steam conduit only needs to be configured in such a shape that the internal space of the upper lid 12 can be effectively used while avoiding the installation positions of the display unit 16 and the operation unit 17. Further, the installation of the steam conduit is not limited to the position described in the first embodiment or the second embodiment. For example, the steam conduit may be installed at a position opposite to the illustrated position.
Moreover, although the said description demonstrated the example in case a heating cooker is a rice cooker, application of this invention is not restricted to a rice cooker.
