[Technical field]

[0001] The present invention relates to a bread machine. [Background technology]

[0002] Conventionally, a bread maker of this type has a main body having a baking chamber (corresponding to the heating chamber of the present invention) and a lid body that covers the opening of the baking chamber and can be opened and closed freely, the lid body being composed of an inner lid body (corresponding to the inner cover of the present invention) and an outer lid body (corresponding to the outer cover of the present invention), with an outlet opening (corresponding to the heat exhaust vent of the present invention) provided in the inner lid body and an outlet opening (corresponding to the lid exhaust vent of the present invention) provided on the back surface of the outer lid body, and with an air passage that exhausts water vapor and heat from within the baking chamber from the inlet opening of the inner lid body to the outlet opening of the outer lid body (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-000281 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a bread maker with such a lid structure, heat rising from the baking chamber is transmitted to the outer lid, causing the temperature of the top surface of the outer lid near the outlet opening to rise, posing a risk of the user being burned.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a bread maker that solves the above problems and prevents a user from getting burned even if he or she touches the lid. [Means for solving the problem]

[0006] The bread making machine described in claim 1 of the present invention is a bread making machine having a main body with a heating chamber inside, a heating container that is removably stored within the heating chamber, a heater provided within the heating chamber, an opening for inserting and removing the heating container into the heating chamber, and a lid body that covers the opening in a manner that allows it to be opened and closed freely, wherein the lid body is composed of an outer cover and an inner cover, a lid exhaust port is provided on the side of the outer cover, a heat exhaust vent and a vent are provided in the inner cover, the space surrounded by the outer cover and the inner cover is a first space portion, a partition member is provided in the first space portion, the space separated from the first space portion by the partition member is a second space portion, and a first heat exhaust path connecting the vent, the first space portion, and the lid exhaust port, and a second heat exhaust path connecting the heat exhaust vent, the second space portion, and the lid exhaust port are provided.

[0007] The bread maker according to claim 2 of the present invention is the bread maker according to claim 1, wherein the first heat exhaust path is provided between the top surface of the outer cover and the second heat exhaust path.

[0008] In addition, the bread maker described in claim 3 of the present invention is a bread maker in which, in claim 1 or claim 2, the first heat exhaust path is connected to the main body space formed between the wall of the heating chamber and the outer shell of the main body, and the second heat exhaust path is connected to the heating chamber. Effect of the Invention

[0009] By configuring the bread maker described in the present invention as described above, the first heat exhaust path connecting the vent hole, the first space, and the lid exhaust port becomes an insulated space, so that heat from the second heat exhaust path connecting the heat exhaust vent hole, the second space, and the lid exhaust port is less likely to be transferred to the outer cover, thereby suppressing the temperature rise of the outer cover and preventing a user from getting burned even if he or she touches the lid.

[0010] Furthermore, by providing the first heat exhaust path between the top surface of the outer cover and the second heat exhaust path, the heat from the second heat exhaust path is less likely to be transmitted to the top surface of the outer cover, which makes it possible to suppress the temperature rise of the top surface of the outer cover and prevents a user from getting burned even if he or she touches the lid.

[0011] Furthermore, since the first heat exhaust path is connected to the main body space and the second heat exhaust path is connected to the heating chamber, the temperature of the first heat exhaust path is lower than the temperature of the second heat exhaust path, which further suppresses the temperature rise of the outer cover and prevents a user from getting burned even if he or she touches the lid.

[0013] Hereinafter, an embodiment of the present invention will be described with reference to Fig. 1 to Fig. 8. In the description of the embodiment, the lower left direction in Fig. 3 is defined as the front, the upper right direction is defined as the rear, the lower right direction is defined as the right, and the upper left direction is defined as the left.

[0014] Reference numeral 1 denotes the bread maker of the present invention. This bread maker 1 is composed of a main body 2 and a lid 3. The main body 2 and the lid 3 are connected by a hinge mechanism 4 provided at the rear of each of them, and this hinge mechanism 4 allows the lid 3 to be moved freely relative to the main body 2 so as to be opened and closed.

[0015] In addition, a touch panel type operation unit 5 is provided on the front side of the main body 2, and this operation unit 5 can be used to select menus, start each menu, etc. (details of the touch panel display and each menu are omitted).

[0016] The main body 2 includes a heating chamber 6, a heating container mounting base 7 provided at the bottom of the heating chamber 6, a motor 8, and a transmission mechanism 9 that transmits the rotation of the motor 8 at a reduced speed.

[0017] Inside the heating chamber 6, there are provided a heating container 10 for accommodating cooking ingredients, a heater 11, and a temperature sensor (not shown) for detecting the temperature inside the heating chamber 6.

[0018] The heating container 10 is detachably attached to the heating container mounting base 7, and is formed in a cylindrical shape with a bottom made of a metal such as aluminum or stainless steel, with at least the inner surface being treated with a fluororesin.

[0019] A shaft 12 that is rotated by the motor 8 and the transmission mechanism 9 is provided at the bottom of the heating container 10. A blade 13 that stirs and kneads the cooking ingredients is detachably attached to this shaft 12.

[0020] The blade 13 includes a boss portion 14 having a hole into which the shaft 12 can be fitted, and a flat blade body 15 formed integrally with the boss portion 14 .

[0021] The lid body 3 is composed of an outer cover 16 and an inner cover 17. The outer cover 16 is composed of an inner lid 18, a top lid 19, and a top panel 20. Furthermore, the inner lid 18 has knob portions 21 formed on the left and right side surfaces.

[0022] The inner cover 17 is made of a metal such as an aluminum-plated steel plate or stainless steel, and serves as a heat shield that prevents the heat generated by the heater 11 from being transmitted to the lid 3 .

[0023] The inner cover 17 is provided with a plurality of ventilation holes 22 on the left and right sides of the front and rear sides. The inner cover 17 is provided with a plurality of exhaust heat vents 23 in the center of the rear side. The exhaust heat vents 23 communicate with a second space 31 (described later) and a lid exhaust port 24 provided on the rear side of the inner lid 18. The heating chamber 6 has an opening 25 at the top, and this opening 25 is composed of an upper body 26 and a heating chamber cover 27. In addition, the heating container 10 can be inserted and removed through this opening 25.

[0024] The opening 25 is covered by the lid 3 so as to be freely opened and closed.

[0025] The upper body 26 is provided with a plurality of vents 28 on the left and right sides of the front and rear sides. When the lid 3 is closed, the vents 22 of the inner cover 17 and the vents 28 of the upper body 26 are arranged to be positioned opposite each other. By arranging them in this manner, the main body space 29 formed between the outer shell of the main body 2 and the heating chamber 6, the first space 30 described below, and the lid exhaust port 24 communicate with each other through the vents 22 and the vents 28. Meanwhile, the heating chamber 6 communicates with the second space 31 through the exhaust heat vent 23. Furthermore, the first space 30 and the second space 31 communicate with the outside air through the lid exhaust port 24. The path from the main body space 29 through the vents 28, 22, the first space 30, and the lid exhaust port 24 to the outside air acts as a heat exhaust path, and is the first heat exhaust path 34. In contrast to this, the path from the heating chamber 6 through the heat exhaust vent 23, the second space 31, and the lid exhaust port 24 to the outside air also acts as a heat exhaust path, but mainly acts as an exhaust path for water vapor generated in the heating chamber 6. This exhaust path is a second heat exhaust path 35. In addition, main body exhaust ports 33 for exhausting heat within the main body space 29 are provided on the left and right side surfaces and the rear surface of the outer shell of the main body 2.

[0026] The first space 30 is provided inside the lid body 3. The first space 30 is a space surrounded by the inner lid 18, the upper lid 19, and the inner cover 17.

[0027] A second space 31 is provided in the lid 3. The second space 31 is provided on the rear side of the lid 3, and is a space surrounded by the inner cover 17, the partition member 32, and the lid exhaust port 24. The first space 30 and the second space 31 are partitioned by the partition member 32, and do not communicate with each other inside the lid 3. The partition member 32 is sandwiched between the upper lid 19 and the inner cover 17, and is fixed to the rear side of the lid 3 by fixing the upper lid 19 and the inner cover 17 with screws or the like.

[0028] Further, in the vicinity of the lid exhaust port 24, the first space 30 is provided between the top panel 20 and the second space 31. That is, the first heat exhaust path 34 is provided between the top panel 20 and the second heat exhaust path 35.

[0029] In this embodiment, the partition member 32 is positioned so as to separate the center of the lid exhaust port 24, but the position may be changed to be closer to the top or the bottom as appropriate depending on the temperatures of the first heat exhaust path 34 and the second heat exhaust path 35.

[0030] In addition, in this embodiment, the first space 30 and the second space 31 are separated by the partition member 32 and are not connected within the cover body 3. However, depending on the temperatures of the first heat exhaust path 34 and the second heat exhaust path 35, holes or notches may be provided in the partition member 32 as appropriate to partially connect the first space 30 and the second space 31, thereby adjusting the temperatures of the first heat exhaust path 34 and the second heat exhaust path 35.

[0031] Next, the effects of this embodiment will be described, taking the case of making bread with this bread maker 1 as an example.

[0032] When making bread with the bread maker 1, the blades 13 are attached to the shaft 12 of the heating container 10. Then, ingredients are put into the heating container 10, the heating container 10 with the ingredients put in is attached to the heating container mounting base 7, and the lid 3 is closed.

[0033] Then, the power plug (not shown) is inserted into an outlet, the operation unit 5 is operated, a menu is selected, and bread baking is started.

[0034] When bread baking starts, the motor 8 rotates the blades 13 to knead the ingredients. After a certain amount of kneading, the blades 13 stop and the ingredients begin to rest. This kneading and resting process is repeated several times, and the ingredients move on to the primary rise process.

[0035] Once the first rise is complete, the dough is degassed and the process moves to the second rise. Once the second rise is complete, the dough is shaped and the process moves to the shaping and fermentation. Once the shaping and fermentation is complete, the baking process starts and the bread is baked.

[0036] In order to remove the baked bread, the handle 21 is utilized to open the lid 3, the heating container 10 is removed from the heating chamber 6, and the bread is removed from the heating container 10.

[0037] In the baking process of the bread cooking described above, electricity is applied to the heater 11 to generate heat. The heating chamber 6 is heated by the heat, and the bread dough in the heating container 10 is baked.

[0038] A part of the heat generated from the heater 11 in the baking process of bread cooking heats the wall of the heating chamber 6. As a result, the heat generated from the heater 11 also raises the temperature of the main body space 29 formed between the outer shell of the main body 2 and the heating chamber 6. A part of the air heated in the main body space 29 is discharged to the outside from the main body exhaust port 33, and a remaining part of the air passes through the vents 28 and 22 to the first space portion 30, and is further discharged from the lid exhaust port 24. That is, a part of the air heated in the main body space 29 is discharged through the first heat exhaust path 34. In addition, outside air flows into the main body space 29 from a plurality of openings (not shown) provided at the bottom of the main body 2 so as to supplement the air discharged from the main body space 29 to the outside through the first heat exhaust path 34.

[0039] Further, a part of the heat generated by the heater 11 heats the dough in the heating container 10. Then, water vapor is generated from the dough. This water vapor is further heated by the heater 11 and becomes high-temperature water vapor. The heat and high-temperature water vapor in the heating chamber 6 pass through the heat exhaust vent 23 and are transferred to the second space 31. Then, the heat and high-temperature water vapor transferred to the second space 31 are exhausted to the outside from the lid exhaust port 24 provided on the rear side of the inner lid 18. That is, the heat and high-temperature water vapor generated in the heating chamber 6 are exhausted through the second heat exhaust path 35.

[0040] In addition, the temperature of the first space 30 also increases when a part of the heat generated by the heater 11 heats the inner cover 17 .

[0041] As described above, part of the heat generated from the heater 11 heats the main body space 29 through the wall of the heating chamber 6, and part of the heated air heats the first space 30 through the vents 28, 22. In addition, part of the heat generated from the heater 11 heats the inner cover 17, thereby heating the first space 30.

[0042] As described above, the heat and high-temperature water vapor in the heating chamber 6 pass through the heat exhaust vent 23 and heat the second space portion 31 that is in communication with the heating chamber 6 .

[0043] Therefore, when the temperature of the first space 30 heated by the heat arriving through the wall of the heating chamber 6, the main body space 29, and the vents 28, 22 and the heat arriving through the inner cover 17 is compared with the temperature of the second space 31 communicating with the heating chamber 6 through the heat exhaust vent 23, the temperature of the first space 30 is lower. That is, the temperature of the first heat exhaust path 34 is lower than the temperature of the second heat exhaust path 35.

[0044] And, since the first heat exhaust path 34 is between the top panel 20 and the second heat exhaust path 35, the heat of the second heat exhaust path 35, which has a higher temperature, is shielded by the first heat exhaust path 34, which has a lower temperature, and the heat is less likely to be transmitted to the top panel 20, so that it is possible to suppress a rise in temperature of the top surface of the top panel 20. This makes it possible to prevent a user from getting burned even if he or she accidentally touches the top surface of the top panel 20 near the lid exhaust port 24.

[0045] The present invention is not limited to the above embodiment, and various modifications are possible within the scope of the gist of the invention. For example, in the above embodiment, the first heat exhaust path and the second heat exhaust path are connected to the same lid exhaust port, but multiple lid exhaust ports may be provided so that the first heat exhaust path and the second heat exhaust path are connected to separate lid exhaust ports.
