- the structure for a cover of an air vent in a conventional built-in heating cooker is disclosed in Japanese Patent Unexamined Publication No. H5-121155 and Japanese Patent Unexamined Publication No. H8-315974 .
- the cover is disposed over the air vent provided at the back of a top face of a cooker body, or the cover is disposed over an air inlet provided at the bottom of the cooker body and hooked with a spring.
- Figs. 16 and 17 show the conventional cover structure.
- top plate 2 configured with a ceramic plate and so on is fixed inside top frame 1 configuring a top section.
- Air vent 3 is provided at the back of top plate 2 so as to cool components inside the cooker body.
- Cover 4 with numerous fine holes is disposed over air vent 3.
- Cover 4 is placed on multiple vibration-proof rubbers 5 provided on the periphery of air vent 3.
- the present invention offers a highly reliable and user-friendly cooker that prevents ingress of spilled liquids to the cooker body and facilitates the cleaning of the cover.
- a built-in heating cooker of the present invention includes a top section on which multiple first openings are created at least on its one sidewall, and a cover for covering the first openings.
- the cover has multiple second openings only on its sidewall at a predetermined distance from the first openings, and is detachably disposed over the first openings on the top section.
- FIG. 1B Exemplary embodiments of the present invention are described below with reference to drawings.
- the drawings are schematic views and thus do not accurately indicate dimensional positions. For reasons of simplicity, components with the same structure are given the same reference numerals, and their duplicate descriptions are omitted.
- heaters 40 are disposed underneath top section 11 in all cookers of the present invention. As an example, two heaters 40 are illustrated in Fig. 1B. However, the number of heaters 40 is determined in accordance with the specifications of each cooker.
- Curved arrows in the solid line in the drawings indicate the movement of spilled liquids or boiled-over soup.
- Curved arrows in the dotted line indicate the flow of ventilation.
- the exemplary embodiments described hereafter are illustrative and not restrictive.
- first openings 13 for ventilation are created on first sidewall 12 at the back of top section 11 configuring the cooker body so as to cool inside the cooker body.
- Top section 11 is equivalent to top frame 1 and top plate 2 described in the prior art.
- Cover 14 is disposed over first sidewall 12 in a way to cover first openings 13.
- Cover 14 has top face 15, second sidewall 16, and bottom face 17.
- Second openings 18 are created on second sidewall 16.
- Elastic member 19 with a spring force is provided at both ends of cover 14.
- Elastic members 19 are fitted to both ends of first openings 13 such that cover 14 is detachably disposed on top section 11.
- Outer frame 20 delineating the cooker body is positioned inside top section 11, and the cooker body is installed on cabinet 21.
- the air vent at the back has no openings on the top face, and a predetermined distance (for example, about 10 mm) can be secured between first openings 13 and second openings 18.
- a predetermined distance for example, about 10 mm
- both first openings and second openings 18 are created on the upper sidewall of first wall face 22 and second wall face 23 extending from the bottom end of top section 11 and cover 14.
- air that has cooled the cooker's internal space passes through between outer frame 20 and top section 11, and then through first openings 13, cover 14, and second openings 18 to outside.
- first openings 13 and second openings 18 can further be adjusted to configure alternate positions when seen from the back so as to further block the boiled-over soup from passing through, although ventilation to outside is also slowed.
- Detachable cover 14 is easily removed and cleaned. In other words, when second openings 18, the air vent, are stained and clogged, typically by boiled-over soup, detachable cover 14 can be easily removed and washed to keep it clean and regain its original performance. First openings 13 which are exposed when cover 14 is removed can also be cleaned.
- cover 14 is attached using elastic member 19 with a spring force on both ends of cover 14. This allows the simple operation of pushing and pulling to attach and detach it from top section 11 even though cover 14 is disposed at the back, which is a difficult position for attachment. Still more, cover 14 can be firmly fixed to a sidewall, which is normally an unstable face for attachment, without any looseness. As described above, this exemplary embodiment offers a structure that can prevent boiled-over soup from entering the cooker body and also secure cooling performance. In addition, the detachable cover is easy to clean. Accordingly, the present invention offers a highly reliable and user-friendly apparatus which facilitates cleaning and reattachment.
- Elastic member 19 can be integrally made with cover 14, or separately made and fixed to cover 14 by spot welding or screwing. Any material can be used for this elastic member 19 as long as it has spring properties. Any attachment system can also be used. For example, a leaf spring can be provided inside top section 11, and a face with cover 14 can be sandwiched and fixed between the leaf spring and top section 11. Or, if top section 11 and cover 14 are made of magnetic material, a magnet can be provided on both or either part. Alternatively, the same effect is achievable by a tab with a spring structure hooked to top section 11, and detached by a single touch.
- the first exemplary embodiment also refer to the sidewall at the back.
- the same effect is achievable by changing the position of the openings depending on the installation conditions and cooling structure of the cooker body.
- the openings can be provided on the left and right sidewalls in addition to the back, or only on the right sidewall.
- the second exemplary embodiment is described with reference to Figs. 5 and 6.
- Cover 14 has a rough U-shape, and is configured with top face 15, second sidewall 16, and bottom face 17.
- Resin protective frame 24 is provided on both ends of cover 14, and tabs on this protective frame 24 are fitted to holes provided on top face 15 and bottom face 17.
- Protrusion 25 which has a guiding shape and round tip is provided at the center of protective frame 24. Cover 14 and protective frame 24 form an integral component by tab-fitting.
- cover 14 When the cover is attached or detached, the risk of injuring a finger with the edge of the metal cover is preventable, since the user holds the curved resin protective frame 24 without an edge at both ends.
- protrusion 25 provided inside cover 14 is fitted into first openings 13 which is a cooling hole, and thus cover 14 can cover first openings 13 without problems even if there are slight variations in attachment.
- cover 14 since cover 14 is roughly U-shaped, it can be made of a thin metal (about 0.5 mm) while retaining its strength. Still more, when the cover is wiped with a cloth, the inside of cover 14 can be easily cleaned because its height is about 10 mm and width is thin, about 5 to 10 mm.
- the second exemplary embodiment offers a readily detachable cover.
- the cover is easily attached and detached without risk of injury after cleaning, offering a safe apparatus. It is apparent that the same effects as those in the first exemplary embodiment are achieved.
- cover 14 and protective frame 24 are attached using a tab-fitting.
- mechanical fixing such as bonding and screwing are also applicable.
- Protective frame 24 can also completely cover and be fixed to the ends of cover 14.
- protective frame 24 is attached to both ends of the cover.
- a cover 14 tends to warp, and thus it is preferable to provide another protective frame at the center.
- This offers a neat apparatus without a gap between top section 11 and cover top face 15 when cover 14 is attached.
- a highly reliable apparatus which blocks the boiled-over soup from entering inside cover 14 via the gap is offered.
- Cover 14 is configured with two short covers, which are respectively disposed on first sidewall 12 at the back of top section 11 in a detachable manner.
- each short cover is a half or shorter than one side length of the cooker body, i.e., about 25 cm long. Accordingly, covers are compact and easy to clean if they become stained. In addition, these covers do not require a large space for drying after cleaning. Still more, these covers have a size small enough to be placed in a widespread dishwasher, facilitating cleaning.
- the third exemplary embodiment employs cover 14 consisting of two parts for offering further easy-care apparatus. It is apparent that the same effect as that described in the first exemplary embodiment is also achieved. The same effect as that described in the second exemplary embodiment is also achieved by providing a protective frame on both ends of two covers.
- Cover 14 is configured with two short covers 14a and 14b.
- Resin support 26 is provided at the joint of the two covers.
- Support 26 is firmly fixed to first cover 14a, and is detachably fitted and lightly pressed into the other second cover 14b by a combination of holes and round protrusions.
- Protrusion 27 with a round tip and guiding shape, similar to protective frame 24, is provided at the center of support 26.
- cover 14 is attached to first sidewall 12 of top section 11 is examined.
- Cover 14 is configured as a single part, and it is fixed by lightly pressing protrusion 25 and protrusion 27 of support 26 into first openings 13.
- cover 14 is removed is examined.
- cover 14 can be simply pulled out by holding both ends of protective frame 24, since cover 14 is a single part (i.e., removal by a single operation).
- first short cover 14a and second short cover 14b of cover 14 are adjoined only by support 26, and thus cover 14 can be divided to first short cover 14a including support 26 and second short cover 14b. This makes the size of cover 14 more compact, and allows easy cleaning when stained and drying after cleaning in a small space.
- these short covers 14a and 14b are small enough to be placed in a widespread dishwasher, further facilitating cleaning.
- the cover is configured in a way that it can be mounted as a single integral part, and then divided into two parts after removal. This offers an easy-care apparatus which allows single operation for attaching the cover to the top plate, and also facilitates cleaning. It is apparent that the same effects as those described in the first to third exemplary embodiments are also achieved.
- support 26 is hidden inside first short cover 14a and second short cover 14b when the covers are adjoined.
- top face 15 of the cover and the top face of support 26 can be leveled and support 26 can be exposed on attachment.
- U-shaped support 26 can be fitted to the cover end from the outside. The same effect is also achieved with these structures.
- the fifth exemplary embodiment is described next with reference to Figs. 9 and 10.
- the basic structure is the same as the first exemplary embodiment, and thus only the parts of the structures that are different are described below.
- Bottom face 17 of cover 14 has short parts 28 whose length in the attachment direction is shorter than the length of top face 15 of cover 14 in the attachment direction, and third openings 29 are formed on these parts.
- the operation and effect of the ventilation structure of the cooker as configured above are described next. Also for the operation and effect, only those parts different from the first exemplary embodiment are described. The case where cover 14 is attached to first sidewall 12 of top section 11 is examined.
- the ventilation area in the cooling structure of cover 14 increases, leading to improved cooling performance.
- These third openings 29 are formed on the bottom face, and the presence of first wall face 22 blocks ingress of liquid into the cooker body.
- liquid-blocking capability can be maintained because third openings 29 do not have a detrimental effect on the liquid-blocking measure.
- the fifth exemplary embodiment increases the ventilation area (i.e., improved cooling performance) on the cover without affecting the liquid-blocking capability. Accordingly, this exemplary embodiment can offer a highly reliable apparatus which achieves both good liquid-blocking performance and cooling performance. Needless to say, it is difficult, in general, to achieve both liquid-blocking performance and cooling performance. It is apparent that the same effects as those described in the first to fourth exemplary embodiments are achieved.
- FIG. 11 and 12 The sixth exemplary embodiment is described next with reference to Figs. 11 and 12. As shown in Figs. 11 and 12, the basic structure is the same as the second exemplary embodiment, and thus only the parts of the structures that are different are described below.
- Top face 15 and bottom face 17 of cover 14 have the same length in the attachment direction.
- Protrusion 25 of protective frame 24 is positioned at the center with respect to the height direction of cover 14.
- cover 14 is attached to first sidewall 12 of top section 11 is examined. According to the above configuration, cover 14 is attached at the center of first openings 13. Next, the case where cover 14 is attached upside down is examined. Since cover 14, protective frame 24, and protrusion 25 are symmetrically shaped on the left and right and up and down, cover 14 can be attached upside down onto first sidewall 12 of top section 11 without any inconvenience.
- cover 14 can be attached to top section 11 without confirming the top and bottom in the sixth exemplary embodiment. Accordingly, the present invention offers an apparatus in which cover 14 can be easily attached without making the user confused. In addition, both good liquid-blocking performance and cooling performance are made feasible. It is apparent that the same effects as those described in the first to fifth exemplary embodiments are also achieved.
- the seventh exemplary embodiment is described next with reference to Fig. 13.
- the basic structure is the same as the second exemplary embodiment, and thus only the parts of the structures that are different are described below.
- Top face 15 of cover 14 is attached to first openings 13 in a way such that top face 15 is inclined downward from the side of top section 11.
- the operation and effect of the ventilation structure of the cooker as configured above are described next. Also for the operation and effect, only those parts different from the first exemplary embodiment are described.
- the case of spilling over soup at the back of top section 11 is examined. The boiled-over soup spills on top section 11, and drips onto cover top face 15.
- top face 15 is inclined downward from the side of top section 11, the boiled-over soup spills along the slope and drips onto the outer face of the cooker body. Accordingly, no spilled liquid pools on cover top face 15, and thus no liquid enters inside cover 14 from a gap between first sidewall 12 and cover top face 15.
- the seventh exemplary embodiment offers a highly reliable apparatus that makes the boiled-over soup completely runs outside of the cooker body even when the soup is spilled. It is apparent that the same effects as those described in the first to sixth exemplary embodiments are also achieved.
- the eighth exemplary embodiment is described next with reference to Fig. 14.
- the basic structure is the same as the first exemplary embodiment, and thus only the parts of the structures that are different are described below.
- Sealing material 30 is applied to a contact face of cover top face 15 and bottom face 17 and first sidewall 12 of top section 11 in a way such that to surround an edge of cover 14.
- the operation and effect of the ventilation structure of the cooker as configured above are described next. Also for the operation and effect, only those parts different from the first exemplary embodiment are described.
- the case of spilling over soup at the back of top section 11 is examined.
- the boiled-over soup spills on top section 11, and drips to cover top face 15.
- the eighth exemplary embodiment offers a highly reliable apparatus that makes the boiled-over soup completely spill over outside of the cooker body even when the soup is spilled. It is apparent that the same effects as those described in the first to seventh exemplary embodiments are also achieved.
- Sealing material 30 is typically provided by applying silicone foam or sealing tape on the edge.
- the ninth exemplary embodiment is described next with reference to Fig. 15.
- the basic structure is the same as the second exemplary embodiment, and thus only the parts of the structures that are different are described below.
- Cover top face 15 is fixed at a position lower than top section 11.
- the operation and effect of the ventilation structure of the cooker as configured above are described next. Also for the operation and effect, only those parts different from the first exemplary embodiment are described. Other parts are the same as the first exemplary embodiment.
- the case where a pot heated at the back of top section 11 is further moved backward is examined. Since cover 14 is disposed at a position lower than top section 11, the pot does not contact cover 14. The pot can thus be placed stably, and cover 14 can also be firmly secured onto top section 11. In addition, even when cover 14 is made of resin, cover 14 does not melt by the heat because there is no chance that the pot contacts cover 14, assuring the safe use.
- the ninth exemplary embodiment offers a highly safe apparatus that enables stable placement of the pot and firm holding of the cover even when the pot significantly deviates and moves backward. It is apparent that the same effects as those described in the first to eighth exemplary embodiments are also achieved.
- the cooker of the present invention has an air vent on the top section, and has a structure which makes liquids spilled over the top plate extremely difficult to pass through inside the cooker body. Accordingly, the present invention offers a highly reliable cooker. Moreover, the cooker of the present invention has a simple detachable cover which can be easily removed when the boiled-over soup sticks to the cover. Accordingly, the present invention also offers an easy-care cooker that can be easily cleaned.
- the built-in heating cooker of the present invention has a ventilation structure that both features effective countermeasures against spilled liquids and good cooling performance, and an easy-care cover structure. Accordingly, the cooker of the present invention is broadly applicable for use typically in apparatuses having air vents near liquids (e.g., cooking appliances, household appliances) and built-in appliances that may be exposed to spilled liquids.

- Exemplary embodiments of the present invention are described below with reference to drawings. The drawings are schematic views and thus do not accurately indicate dimensional positions. For reasons of simplicity, components with the same structure are given the same reference numerals, and their duplicate descriptions are omitted. It is apparent that
heaters 40 are disposed underneathtop section 11 in all cookers of the present invention. As an example, twoheaters 40 are illustrated in Fig. 1B. However, the number ofheaters 40 is determined in accordance with the specifications of each cooker. Curved arrows in the solid line in the drawings indicate the movement of spilled liquids or boiled-over soup. Curved arrows in the dotted line indicate the flow of ventilation. The exemplary embodiments described hereafter are illustrative and not restrictive. - The first exemplary embodiment is described next with reference to Figs. 1A to 4. In Figs. 1A to 4,
first openings 13 for ventilation are created onfirst sidewall 12 at the back oftop section 11 configuring the cooker body so as to cool inside the cooker body.Top section 11 is equivalent totop frame 1 andtop plate 2 described in the prior art. -
Cover 14 is disposed overfirst sidewall 12 in a way to coverfirst openings 13.Cover 14 hastop face 15,second sidewall 16, andbottom face 17.Second openings 18 are created onsecond sidewall 16.Elastic member 19 with a spring force is provided at both ends ofcover 14.Elastic members 19 are fitted to both ends offirst openings 13 such thatcover 14 is detachably disposed ontop section 11.Outer frame 20 delineating the cooker body is positioned insidetop section 11, and the cooker body is installed oncabinet 21. - In this structure, the air vent at the back has no openings on the top face, and a predetermined distance (for example, about 10 mm) can be secured between
first openings 13 andsecond openings 18. In addition, both first openings andsecond openings 18 are created on the upper sidewall offirst wall face 22 andsecond wall face 23 extending from the bottom end oftop section 11 andcover 14. As shown in Fig. 2, air that has cooled the cooker's internal space passes through betweenouter frame 20 andtop section 11, and then throughfirst openings 13,cover 14, andsecond openings 18 to outside. - The operation and effect of the ventilating structure of the cooker as configured above are described next. First, the case of spilling over soup at the back of
top section 11 is examined. The boiled-over soup spills alongtop section 11,top face 15 ofcover 14, and then drips ontocabinet 21. Sincecover 14 is attached totop section 11, and no openings are provided ontop face 15, the boiled-over soup does not enterinside cover 14. Moreover, even though a large volume of boiled-over soup spills ontocover 14, most of the liquid that arrives oncabinet 21 is blocked bysecond wall face 23 on the same plane as thesecond sidewall 16 ofcover 14, and thus not so much of the liquid enters insidecover 14. However, sincesecond openings 18 for cooling the cooker's internal space are provided, a small amount of boiled-over soup does penetrate inside. However, the boiled-over soup that passes throughsecond openings 18 pools in a space insidecover 14, and thus does not yet enter the cooker. The further ingress of boiled-over soup is also blocked byfirst sidewall 12 oftop section 11 andfirst wall face 22, and thus almost no boiled-over soup enters inside the cooker body. - The relative positions of
first openings 13 andsecond openings 18 can further be adjusted to configure alternate positions when seen from the back so as to further block the boiled-over soup from passing through, although ventilation to outside is also slowed. -
Detachable cover 14 is easily removed and cleaned. In other words, whensecond openings 18, the air vent, are stained and clogged, typically by boiled-over soup,detachable cover 14 can be easily removed and washed to keep it clean and regain its original performance.First openings 13 which are exposed whencover 14 is removed can also be cleaned. - Still more, cover 14 is attached using
elastic member 19 with a spring force on both ends ofcover 14. This allows the simple operation of pushing and pulling to attach and detach it fromtop section 11 even thoughcover 14 is disposed at the back, which is a difficult position for attachment. Still more, cover 14 can be firmly fixed to a sidewall, which is normally an unstable face for attachment, without any looseness. As described above, this exemplary embodiment offers a structure that can prevent boiled-over soup from entering the cooker body and also secure cooling performance. In addition, the detachable cover is easy to clean. Accordingly, the present invention offers a highly reliable and user-friendly apparatus which facilitates cleaning and reattachment. -
Elastic member 19 can be integrally made withcover 14, or separately made and fixed to cover 14 by spot welding or screwing. Any material can be used for thiselastic member 19 as long as it has spring properties. Any attachment system can also be used. For example, a leaf spring can be provided insidetop section 11, and a face withcover 14 can be sandwiched and fixed between the leaf spring andtop section 11. Or, iftop section 11 and cover 14 are made of magnetic material, a magnet can be provided on both or either part. Alternatively, the same effect is achievable by a tab with a spring structure hooked totop section 11, and detached by a single touch. - The first exemplary embodiment also refer to the sidewall at the back. However, the same effect is achievable by changing the position of the openings depending on the installation conditions and cooling structure of the cooker body. For example, the openings can be provided on the left and right sidewalls in addition to the back, or only on the right sidewall.
- The second exemplary embodiment is described with reference to Figs. 5 and 6. As shown in Fig. 5, the basic structure is the same as in the first exemplary embodiment, and thus only the parts of the structure that are different from the first exemplary embodiment are described.
Cover 14 has a rough U-shape, and is configured withtop face 15,second sidewall 16, andbottom face 17. Resinprotective frame 24 is provided on both ends ofcover 14, and tabs on thisprotective frame 24 are fitted to holes provided ontop face 15 andbottom face 17.Protrusion 25 which has a guiding shape and round tip is provided at the center ofprotective frame 24.Cover 14 andprotective frame 24 form an integral component by tab-fitting. The operation and effect of the ventilation structure of the built-in heating cooker as configured above are described. Only the details which are different from the first exemplary embodiment are described. Other parts are the same as in the first exemplary embodiment. The case wherecover 14 is attached totop section 11 is examined.First openings 13 for cooling are created onfirst sidewall 12 oftop section 11, andprotrusion 25 ofprotective frame 24 is inserted into these first openings.Protrusion 25 is made of resin, and thus it slightly dents and is pushed intofirst openings 13.Protrusion 25 is firmly fixed totop section 11 when it is further inserted.Protective frame 24 is fixed to the extent that the user can easily detach it, and thus removal is also easy. If the cover is made of metal, the edge can be covered with a resin protective frame. When the cover is attached or detached, the risk of injuring a finger with the edge of the metal cover is preventable, since the user holds the curved resinprotective frame 24 without an edge at both ends. In addition,protrusion 25 provided insidecover 14 is fitted intofirst openings 13 which is a cooling hole, and thus cover 14 can coverfirst openings 13 without problems even if there are slight variations in attachment. In addition, sincecover 14 is roughly U-shaped, it can be made of a thin metal (about 0.5 mm) while retaining its strength. Still more, when the cover is wiped with a cloth, the inside ofcover 14 can be easily cleaned because its height is about 10 mm and width is thin, about 5 to 10 mm. As described above, the second exemplary embodiment offers a readily detachable cover. In addition, the cover is easily attached and detached without risk of injury after cleaning, offering a safe apparatus. It is apparent that the same effects as those in the first exemplary embodiment are achieved. - In this exemplary embodiment, cover 14 and
protective frame 24 are attached using a tab-fitting. However, mechanical fixing such as bonding and screwing are also applicable.Protective frame 24 can also completely cover and be fixed to the ends ofcover 14. - In the description,
protective frame 24 is attached to both ends of the cover. However, too long acover 14 tends to warp, and thus it is preferable to provide another protective frame at the center. This offers a neat apparatus without a gap betweentop section 11 and covertop face 15 whencover 14 is attached. In addition, a highly reliable apparatus which blocks the boiled-over soup from entering insidecover 14 via the gap is offered. - The third exemplary embodiment is described with reference to Fig. 7. The basic structure is the same as the first exemplary embodiment, and thus only the parts of the structure that are different are described below.
Cover 14 is configured with two short covers, which are respectively disposed onfirst sidewall 12 at the back oftop section 11 in a detachable manner. - The operation and effect of the ventilation structure of the cooker as configured above are described next. In addition, for the operation and effect, only those parts that differ from the first exemplary embodiment are described. The case where
cover 14 is removed fromtop section 11 is examined. Each short cover is a half or shorter than one side length of the cooker body, i.e., about 25 cm long. Accordingly, covers are compact and easy to clean if they become stained. In addition, these covers do not require a large space for drying after cleaning. Still more, these covers have a size small enough to be placed in a widespread dishwasher, facilitating cleaning. As described above, the third exemplary embodiment employscover 14 consisting of two parts for offering further easy-care apparatus. It is apparent that the same effect as that described in the first exemplary embodiment is also achieved. The same effect as that described in the second exemplary embodiment is also achieved by providing a protective frame on both ends of two covers. - The fourth exemplary embodiment is described next with reference to Figs. 8A and 8B. As shown in Figs. 8A and 8B, the basic structure is the same as the second exemplary embodiment, and thus only the parts of the structures that are different are described below.
Cover 14 is configured with twoshort covers Resin support 26 is provided at the joint of the two covers.Support 26 is firmly fixed tofirst cover 14a, and is detachably fitted and lightly pressed into the othersecond cover 14b by a combination of holes and round protrusions.Protrusion 27 with a round tip and guiding shape, similar toprotective frame 24, is provided at the center ofsupport 26. - The operation and effect of the ventilation structure of the cooker as configured above are described next. Also for the operation and effect, only those parts different from the second exemplary embodiment are described. The case where
cover 14 is attached tofirst sidewall 12 oftop section 11 is examined.Cover 14 is configured as a single part, and it is fixed by lightly pressingprotrusion 25 andprotrusion 27 ofsupport 26 intofirst openings 13. Next, the case wherecover 14 is removed is examined. To removecover 14, it can be simply pulled out by holding both ends ofprotective frame 24, sincecover 14 is a single part (i.e., removal by a single operation). However, firstshort cover 14a and secondshort cover 14b ofcover 14 are adjoined only bysupport 26, and thus cover 14 can be divided to firstshort cover 14a including support 26 and secondshort cover 14b. This makes the size ofcover 14 more compact, and allows easy cleaning when stained and drying after cleaning in a small space. In addition, theseshort covers - In the fourth exemplary embodiment as described above, the cover is configured in a way that it can be mounted as a single integral part, and then divided into two parts after removal. This offers an easy-care apparatus which allows single operation for attaching the cover to the top plate, and also facilitates cleaning. It is apparent that the same effects as those described in the first to third exemplary embodiments are also achieved.
- In the fourth exemplary embodiment,
support 26 is hidden inside firstshort cover 14a and secondshort cover 14b when the covers are adjoined. However, other structures are also applicable. For example,top face 15 of the cover and the top face ofsupport 26 can be leveled andsupport 26 can be exposed on attachment. Alternatively,U-shaped support 26 can be fitted to the cover end from the outside. The same effect is also achieved with these structures. - The fifth exemplary embodiment is described next with reference to Figs. 9 and 10. As shown in Figs. 9 and 10, the basic structure is the same as the first exemplary embodiment, and thus only the parts of the structures that are different are described below. Bottom face 17 of
cover 14 hasshort parts 28 whose length in the attachment direction is shorter than the length oftop face 15 ofcover 14 in the attachment direction, andthird openings 29 are formed on these parts. The operation and effect of the ventilation structure of the cooker as configured above are described next. Also for the operation and effect, only those parts different from the first exemplary embodiment are described. The case wherecover 14 is attached tofirst sidewall 12 oftop section 11 is examined. Sinceshort parts 28 are present onbottom face 17 ofcover 14, newthird openings 29 are created in a space surrounded bycover 14 andfirst sidewall 12 in addition tosecond openings 18. In other words, the ventilation area in the cooling structure ofcover 14 increases, leading to improved cooling performance. Thesethird openings 29 are formed on the bottom face, and the presence offirst wall face 22 blocks ingress of liquid into the cooker body. In other words, liquid-blocking capability can be maintained becausethird openings 29 do not have a detrimental effect on the liquid-blocking measure. As described above, the fifth exemplary embodiment increases the ventilation area (i.e., improved cooling performance) on the cover without affecting the liquid-blocking capability. Accordingly, this exemplary embodiment can offer a highly reliable apparatus which achieves both good liquid-blocking performance and cooling performance. Needless to say, it is difficult, in general, to achieve both liquid-blocking performance and cooling performance. It is apparent that the same effects as those described in the first to fourth exemplary embodiments are achieved. - The sixth exemplary embodiment is described next with reference to Figs. 11 and 12. As shown in Figs. 11 and 12, the basic structure is the same as the second exemplary embodiment, and thus only the parts of the structures that are different are described below.

Also for the operation and effect, only those parts different from the second exemplary embodiment are described. First, the case where
cover 14 is attached tofirst sidewall 12 oftop section 11 is examined. According to the above configuration, cover 14 is attached at the center offirst openings 13. Next, the case wherecover 14 is attached upside down is examined. Sincecover 14,protective frame 24, andprotrusion 25 are symmetrically shaped on the left and right and up and down, cover 14 can be attached upside down ontofirst sidewall 12 oftop section 11 without any inconvenience. - As described above, cover 14 can be attached to
top section 11 without confirming the top and bottom in the sixth exemplary embodiment. Accordingly, the present invention offers an apparatus in which cover 14 can be easily attached without making the user confused. In addition, both good liquid-blocking performance and cooling performance are made feasible. It is apparent that the same effects as those described in the first to fifth exemplary embodiments are also achieved. - The seventh exemplary embodiment is described next with reference to Fig. 13. As shown in Fig. 13, the basic structure is the same as the second exemplary embodiment, and thus only the parts of the structures that are different are described below.
Top face 15 ofcover 14 is attached tofirst openings 13 in a way such thattop face 15 is inclined downward from the side oftop section 11. The operation and effect of the ventilation structure of the cooker as configured above are described next. Also for the operation and effect, only those parts different from the first exemplary embodiment are described. The case of spilling over soup at the back oftop section 11 is examined. The boiled-over soup spills ontop section 11, and drips onto covertop face 15. Sincetop face 15 is inclined downward from the side oftop section 11, the boiled-over soup spills along the slope and drips onto the outer face of the cooker body. Accordingly, no spilled liquid pools on covertop face 15, and thus no liquid enters insidecover 14 from a gap betweenfirst sidewall 12 and covertop face 15. - As described above, the seventh exemplary embodiment offers a highly reliable apparatus that makes the boiled-over soup completely runs outside of the cooker body even when the soup is spilled. It is apparent that the same effects as those described in the first to sixth exemplary embodiments are also achieved.
- The eighth exemplary embodiment is described next with reference to Fig. 14. As shown in Fig. 14, the basic structure is the same as the first exemplary embodiment, and thus only the parts of the structures that are different are described below. Sealing
material 30 is applied to a contact face of covertop face 15 andbottom face 17 andfirst sidewall 12 oftop section 11 in a way such that to surround an edge ofcover 14. The operation and effect of the ventilation structure of the cooker as configured above are described next. Also for the operation and effect, only those parts different from the first exemplary embodiment are described. The case of spilling over soup at the back oftop section 11 is examined. The boiled-over soup spills ontop section 11, and drips to covertop face 15. Since sealingmaterial 30 covers the edge of covertop face 15 contactingtop section 11 so as to eliminate any gap betweenfirst sidewall 12 andcover 14, no liquid directly enters insidecover 14. Consequently, the boiled-over soup completely runs outside. As described above, the eighth exemplary embodiment offers a highly reliable apparatus that makes the boiled-over soup completely spill over outside of the cooker body even when the soup is spilled. It is apparent that the same effects as those described in the first to seventh exemplary embodiments are also achieved. - Sealing
material 30 is typically provided by applying silicone foam or sealing tape on the edge. - The ninth exemplary embodiment is described next with reference to Fig. 15. As shown in Fig. 15, the basic structure is the same as the second exemplary embodiment, and thus only the parts of the structures that are different are described below. Cover
top face 15 is fixed at a position lower thantop section 11. The operation and effect of the ventilation structure of the cooker as configured above are described next. Also for the operation and effect, only those parts different from the first exemplary embodiment are described. Other parts are the same as the first exemplary embodiment. The case where a pot heated at the back oftop section 11 is further moved backward is examined. Sincecover 14 is disposed at a position lower thantop section 11, the pot does not contactcover 14. The pot can thus be placed stably, and cover 14 can also be firmly secured ontotop section 11. In addition, even whencover 14 is made of resin, cover 14 does not melt by the heat because there is no chance that the pot contacts cover 14, assuring the safe use. - As described above, the ninth exemplary embodiment offers a highly safe apparatus that enables stable placement of the pot and firm holding of the cover even when the pot significantly deviates and moves backward. It is apparent that the same effects as those described in the first to eighth exemplary embodiments are also achieved.
- The cooker of the present invention has an air vent on the top section, and has a structure which makes liquids spilled over the top plate extremely difficult to pass through inside the cooker body. Accordingly, the present invention offers a highly reliable cooker. Moreover, the cooker of the present invention has a simple detachable cover which can be easily removed when the boiled-over soup sticks to the cover. Accordingly, the present invention also offers an easy-care cooker that can be easily cleaned.
- The built-in heating cooker of the present invention has a ventilation structure that both features effective countermeasures against spilled liquids and good cooling performance, and an easy-care cover structure.
