There is a demand for a heating cooker that can perform cooking including the use of liquid, and in this case, in consideration of cleaning after cooking, it is desirable that the container for storing the food is removable.

However, in Patent Document 1, it is not assumed that liquid is poured into the grilling plate and stored therein, and therefore, lifting of foodstuffs from the liquid is not considered.

Further, in Patent Document 2, like Patent Document 1, it is not assumed that foodstuffs are pulled up.

In view of the above, the present invention relates to a heating cooker that can perform cooking including the use of liquid, and in which a container for storing foodstuffs can be easily attached and detached.

From the above, in the present invention, a removable container is housed in a heating chamber formed by an upper lid and a lower lid, and an object to be heated is heated with a liquid in the container, and the container has a handle. a removable first container with a handle; and a second receptacle with a handle and removable and housed within the first container, the handle of the first container and the handle of the second container comprising: A cooking device characterized in that at least a portion of each handle overlaps when viewed from above, and the second container is raised and lowered by a raising and lowering means.

According to the present invention, it is possible to provide a heating cooker that can perform cooking including using liquid and has a container for storing food that can be easily attached and detached.

Specifically, according to the embodiment of the present invention, by providing two means: "the handles overlap" and "the second container in which the food is placed can be raised and lowered by the lifting means", In addition to when each container is attached to and detached from the main body, when the first and second containers are overlapped and attached to and detached from the main body, it is easy to attach and detach without impairing the weight balance. In addition, there is the advantage that even when pushing up near the handle of the second container during the cooking process, it can be raised stably.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of a heating cooker according to an embodiment of the present invention in an open state. The cooking device 1 has an upper lid 2a and a lower lid 2b rotatably supported by a hinge 4, thereby forming a heating chamber 3 therein. A container 5 in which food is placed and cooked is housed in the space inside the heating chamber 3, and the food is cooked by an upper heater 6a installed on the back side of the upper lid 2a (on the heating chamber side). Although not shown, a lower heater may be provided on the heating chamber side of the lower lid 2b. Also, when the hinge 4 side is the rear side and the opposite side is the front side, the upper lid 2a and the lower lid 2b are locked facing each other on the front side, and there is also a push button to release the locking and open the upper lid 2a. A button 7 is provided.

FIG. 2 is a three-sided view showing the appearance of the heating cooker according to the embodiment of the present invention in a closed state. The heating cooker 1, whose appearance is formed by the upper lid 2a and the lower lid 2b, has a generally box-like shape. According to a plan view of the heating cooker 1 when viewed from above, an operation panel 8 for operation and display is provided on the front upper surface of the heating cooker 1. According to the front view, a push button 7 is provided for opening, closing, and locking the upper lid 2a. Further, according to the right side view when the cooking device 1 is viewed from the right side, an engagement line 9 between the upper lid 2a and the lower lid 2b is visible.

What is characteristic about this figure is that the hinge 4 is located at a relatively high position, and the thickness H2 of the front upper lid 2a is larger than the thickness H1 of the rear upper lid 2a. This is referred to as the engagement line 9. In other words, the height of the bottom lid is lower at the front and higher at the rear. Due to the large thickness H2 of the front upper lid 2a, it is possible to secure a distance between the upper heater 2a, which is an internal heating source, and the operation panel 8, and it is easy to insulate the operation panel 8, so that the operation panel 8 can be placed on the front upper surface. .

FIG. 3 is a perspective view showing the external appearance of the heating cooker according to the embodiment of the present invention, including a container that can be placed in an open state. According to this figure, the container 5, which is the contents installed in the heating chamber 3 formed by the upper lid 2a and the lower lid 2b, has been removed. The container 5 stored in the recess formed by the lower lid 2b includes a first container 5A placed below and a second container 5B having a size and shape that can be accommodated in the first container 5A. It is made up of. Further, the lower lid 2b is provided with an elevating section 10 that moves up and down in the height direction, so that only the second container 5B can be moved up and down, as will be described later. Note that a lower heater 6b may be installed on the upper surface of the lower lid 2b inside the heating chamber 3.

The first container 5A is composed of a container main body 5A1 and two handles 5A2 provided at opposing positions and having a hole 5A3 formed therein. The first container 5A can be stably placed in the heating chamber 3 by placing the two handles 5A2 on the upper surface of the lower lid 2b or by seating the container body 5A1 in the recess formed by the lower lid 2b. Installed removably. Water, seasoning liquid, and ingredients are put in the container body 5A1 of the first container 5A, and boiled food can be cooked by heating the container body 5A1 with the upper and lower heaters 6a and 6b.

The second container 5B includes a container main body 5B1 in which a drainage portion 5B3 is formed, and two handles 5B2 provided at opposing positions. The second container 5B is placed in the heating chamber 3 with the two handles 5B2 placed on the upper surface of the elevating part 10 provided on the lower lid 2b. Further, the container body 5B1 of the second container 5B has a size and shape that can be stored in the container body 5A1 of the first container 5A, so that the first container 5A and the second container 5B are They can be installed in the heating chamber 3 in a stacked state. By putting food into the second container 5B and storing it in the first container 5A containing water and seasoning liquid, the food can be soaked, and the second container 5B can be moved by the lifting section 10. The food can be steamed or grilled by heating from the heaters 6a and 6b on the upper and lower sides.

Furthermore, in the stacked storage state of the two containers 5A and 5B, the handle 5A2 of the first container 5A and the handle 5B2 of the second container 5B are arranged so that at least a portion of them in the vertical direction is the same. Thereby, the two containers 5A and 5B can be attached and detached at the same time while remaining in the stacked storage state. Note that the container body and handle of these containers may be molded integrally or may be molded separately.

As shown in FIG. 4 showing the combined state of the handles of the two containers, the lifting section 10 is fitted into the hole 5A3 formed in the two handles 5A2 of the first container 5A. An example is shown in which two handles 5B2 of the second container 5B are supported on the upper surface and the second container 5B is moved up and down.

What is characteristic of this figure is that two containers are used one on top of the other, and only the second container 5B is operated up and down using the handle portion and the lifting section 10. Note that various engagement relationships between the handle portion and the lifting portion 10 can be adopted as described in the second embodiment.

Thus, the second container 5B can take at least two installation positions in the height direction. Figures 5a and 5b show right side sectional views in the lower and upper positions, respectively. In the lower position of FIG. 5A, the first container 5A is seated on the bottom surface of the heating chamber 3, or is stably housed in the heating chamber 3 with its handle 5a2 in contact with the upper surface of the lower lid 2b. . Further, the second container 5B is stably stored in the first container 5A by being seated on the bottom surface of the first container 5A, or by having its handle 5b2 abut against the handle 5a2 or the top surface of the lifting section 10. ing. If water and seasoning liquid 11 are placed in the first container 5A in this state, the food in the second container 5A will be immersed.

At the time of FIG. 5b, the first container 5A remains in the seated state, and the handle 5b2 of the second container 5B is lifted by the lifting section 10 to reach the upper position shown in the figure. At this time, the water and seasoning liquid 11 fall from the drainage part 5B3 into the first container 5A, and the food can be positioned in the space, so the food can be steamed or baked by heating from the upper and lower heaters 6a and 6b. Can cook. Particularly in the case of grilling, the food can be browned by bringing it into direct contact with the upper heater 6a.

In FIGS. 5a and 5b, reference numeral 12 denotes a control unit composed of a control board that controls the display on the operation panel 8, the heater, the lifting means 10, and the like. The control board 12 is generally sensitive to heat, but as shown in the right side view of FIG. 2, the thickness H2 of the upper lid 2a on the front side is increased, so that the distance from the upper heater 6a can be increased. The structure is easy to insulate.

Furthermore, in FIGS. 5a and 5b, the engagement line 9 of the upper lid 2a and the lower lid 2b is located at a lower position than the handle of the container on the front side of the cooking device. This makes it possible to secure space when removing the container and to make it easy to take out.

Furthermore, in FIGS. 5a and 5b, the hinge 4 for rotating the top lid 2a is located at the rear of the main body and higher than the height position where the removable containers 5A and 5B are set on the front of the main body, so that the upper lid 2a can be rotated. Since the rear part is thin, the amount of protrusion toward the rear of the main body when the top lid 2a is opened can be shortened. Further, by providing the heater 6a on the top lid 2a, even if the top lid 2a becomes heavy, there is an effect that it is difficult to fall backward when the top lid 2a is opened.

Attachment and removal of the container will be explained with reference to FIGS. 6a, 6b, and 6c. First, FIG. 6a shows the container before and after it is attached. In the right figure before installation, since the front side thickness H2 is larger than the engagement line 9 of the upper cover 2a and lower cover 2b, the heating chamber 3 expands greatly when the upper cover 2a is opened upward, especially on the front side (near side). (side) is located low, making it easy to see into the interior, making it easy to attach containers. This structure also makes it easy to clean after use. The left figure after installation shows a state where the second container 5B is installed in the upper position of the lifting part 10, and the second container 5B is placed in the upper position with the lifting part 10 fitted with the hole 5A3 of the handle 5A2. The state in which the container 5B is installed is shown. It should be noted that in the initial state (the state in which the top lid 2a is opened to start cooking), it is only necessary to decide as appropriate whether the elevating part 10 should be placed in the upper or lower position. An example is shown.

FIG. 6b shows a state in which the second container 5B is removed when it is in the lower position, and the engagement line 9 of the upper lid 2a and the lower lid 2b is positioned lower than the handle of the container on the front side of the cooking device. This allows a sufficient gap to be provided, ensuring enough space for your fingers when taking it out. Note that although the containers 5A and 5B are lifted together in FIG. 6b, the present invention is not limited to this, and it is also possible to lift only the container 5B.

More specifically, it is easy to provide a sufficient gap (space) between the handle of the container and the main body of the cooker, and therefore, there is also a sufficient gap for the user to insert his or her fingers when attaching or removing the container. Therefore, it is possible to attach and detach the container by holding the handle, and even if there is liquid in the container, it is possible to prevent the liquid from spilling when lifting and removing the container. Note that the same effect can be obtained by providing a recess in the cooking device main body to ensure a gap and placing a removable container in the recess.

FIG. 6c shows a state in which the second container 5B is removed when it is in the upper position, and only the container 5A can be removed after removing the container 5B supported in the upper position.

FIG. 7 is a diagram showing the opening position when the upper lid 2a is opened, and is basically opened in two stages. The first stage opening position is as shown on the left, and is approximately 70 degrees to 80 degrees open. This is the position where the top lid 2a automatically opens and stops due to a spring or the like when the push button 7 is operated. By setting the opening angle to less than 90 degrees, condensation generated during cooking can fall when opened. Also, it does not scatter outside the heating cooker 1 and can be collected in the first container 5A.

The second opening stage on the right is a position that can be taken by manual operation by the user, and is preferably set to approximately 110 degrees of opening. If it is opened to this degree, the angle is such that it will not fall over even if it is opened.

In the state on the right in Figure 7, the heater 6a provided on the top lid 2a can be attached and removed when the top lid 2a is opened from 90 degrees. Falling can be suppressed. Furthermore, if a spring or damper is provided so that the top lid 2a stops at about 75 degrees when opening the top lid 2a, and the top lid 2a opens further when pushed by hand from the stopped position, the main body due to inertia when the top lid 2a opens. It is possible to suppress the vibration of Therefore, even if liquid is present in the container, it is possible to prevent it from rippling and spilling.

Note that the upper heater 6a is preferably removable for cleaning, and in the second opening stage, the upper lid 2a is wide open, so that it can be easily removed. It is also easy to clean the inside. When removing the upper heater 6a, as shown in the center diagram of FIG. In order to prevent this, a locking portion 2a2 is provided on the lower side. This locking portion 2a2 may be provided with a convex portion on the upper heater 6a side and fitted into a concave portion on the top lid 2a side, or alternatively, a concave portion may be provided on the upper heater 6a side and fitted into a convex portion on the top lid 2a side. You may.

In Example 1, as shown in the right side view of FIG. 2, the front side thickness H2 of the upper lid 2a is made larger than the rear side thickness H1 with respect to the engagement line 9. The reason why this should be done is due to the following circumstances at the development stage of the heating cooker. This is because we focused on the fact that when a container is first filled with liquid and then placed in a cooker, the liquid may spill out if the container is tilted during the installation process. Based on this, we considered an operation in which liquid was poured into the container after the container was installed in the cooker. At this time, if the distance from the pouring point to the bottom of the container is long (in other words, if the front wall of the container excluding the lid is high), the liquid will be poured from a high place and the liquid will leak out of the container. I jump. A structure to prevent this is to make the front thickness H2 of the upper lid 2a larger than the rear thickness H1.

As a result, the front side of the cooking appliance main body can be lowered, so that the height direction position for setting the removable container can be lowered. It is possible to reduce splashing of liquid during the process of creating a situation in which liquid is contained in a container installed in a cooking device, and to make it easier to fill the container with liquid.

Also, as a side effect of adopting this structure, the front side is lower, making it easier to look into the container, and since there is no wall at the back that would get in the way when setting the container, it is easier to set the container. The advantage is that the side walls can be configured so that they are not provided on the upper side of the main body. Furthermore, since the front side of the top lid 2a is thick, a heat insulating material can be provided, and an operation panel can be installed on the front side of the top lid 2a.When the top lid 2a is opened after cooking, steam etc. can be used. It is also possible to obtain a configuration that is less likely to affect the user.

In addition, in the first embodiment, in a cooker that heats an object with a liquid (water, enzyme, seasoning liquid) in a container, the cooker has a removable first container 5A (in which the liquid is stored). A second container 5B (container for placing foodstuffs) which is removable and located above the first container 5A, and a lifting means for raising and lowering the second container 5B. The container 5A and the second container each have a handle, and when viewed from above, at least a portion of each handle overlaps, so that the second container 5B, which is arranged one above the other in the height direction, can be raised and lowered. This is possible, and the second container 5B can be lifted stably when going up and down.

In addition, the second container 5B has a hole or space in the bottom (a hole for draining water), so after cooking in the solution, you can drain the hot water (drain the liquid) by raising the second container. The food can be steamed by filling water in the first container 5A, placing food in the second container 5B, and heating the first container 5A.

Furthermore, the elevating means can be stopped (fixing the position of the second container 5B) after raising the second container 5B to a state where the food is out of liquid, so that when heating/cooking is started in this state, Even if you pour water into the first container 5A, which is a pot for steaming, it is possible to avoid soaking the food with water, and the height of the liquid level can be changed in accordance with the steaming time. It may also be possible to change the stop position with , which has the effect of bringing the liquid level closer to the food position and making it easier for steam to hit the food.

In Example 2, a modification of the structure of the elevating section that lifts only the handle of the second container will be described.

In one example, as shown in FIG. 4, the elevating part 10 is fitted into the hole 5A3 formed in the two handles 5A2 of the first container 5A, and the second elevating part 10 is fitted on the upper surface of the elevating part 10. Two handles 5B2 of the container 5B are supported and the second container 5B is moved up and down.

On the other hand, FIG. 8 shows an example in which the lifting section 10 is provided outside the handle 5A2. The width DB of the handle 5B2 is made larger than the width DA of the handle 5A2, and both sides of the handle 5B2 are lifted up by lifting parts 10A and 10B provided at both ends of the handle 5A2.

FIG. 9 shows an example in which the lifting section 10 is provided on the front side of the handle 5A2. The vertical width DB of the handle 5B2 is made larger than the vertical width DA of the handle 5A2, and the front surface of the handle 5B2 is lifted up by an elevating part 10 provided on the front side of the handle 5A2.

10a, FIG. 10b, and FIG. 10c are a side view and a plan view showing the combination relationship in FIGS. 4, 8, and 9, respectively. These are examples of support by fitting, support on the side, and support in front.

FIG. 10d shows a case where the handles 5A2 and 5B2 of the containers 5A and 5B are integrally molded with the container bodies 5A1 and 5B1.

FIG. 10e shows an example in which the elevating means 10 and its receiving portion 13 are arranged at a location different from the handle. As shown in this example, it is not necessary to install the elevating means 10 at the handle as long as it can be lifted stably. However, for stable support, it is important to install at least two of the elevating parts and their receiving parts at opposing positions of the container.

Furthermore, from the viewpoint of stable support and vertical movement, for example, a magnet (or a magnet and an iron piece) may be installed on the upper surface of the elevating means 10 in FIG. It is better to plan.

Moreover, the elevating part 10 may have a stepped shape with a convex part provided on the upper part, and a hole or a recess may be provided in the handle 5B2 of the second container 5B. The convex portion provided on the elevating portion 10 fits into the hole or recess of the handle 5B2 of the second container 5B, so that the second container 5B can be stably supported and moved up and down.

Alternatively, the elevating part 10 may have a shape with a recessed part in the upper part, and a convex part may be provided in the handle 5B2 of the second container 5B. By fitting the concave portion provided in the elevating portion 10 into the convex portion of the handle 5B2 of the second container 5B, the second container 5B can be stably supported and moved up and down.

In Example 3, a description will be given of reducing the height of the heating cooker and making it smaller. In order to reduce the height of the heating cooker, in the third embodiment, the internal structure of the upper lid shown in FIG. 11 is devised.

The right view of FIG. 11 is a sectional view taken along line AA of the handle portion in the front view of FIG. When the second container 5B is in the upper position, the height of this part is determined by the thickness of the two handles 5A2 and 5B2 and the extension of the elevating part 10, and if the height of this part can be lowered, the whole will be smaller. can contribute to the development of

In the left diagram of FIG. 11, a recess is formed in the portion where the two handles 5B2 of the second container 5B abut inside the top lid 2a in the upper position, and the handles 5B2 are housed inside the recess. It is something.

According to FIG. 11, a container equipped with a handle is configured such that the handle is located at the highest position (the height of the side of the container that is not provided with the handle is configured lower), and a recess is provided in the top lid 2a. The thickness of the top lid 2a ( Since the front side is thicker than the rear side, the upper lid 2a can be provided with a recess for accommodating the handle of the container. Moreover, by putting the handle of the container into the recess of the upper lid 2a, the height of the entire cooking device can be lowered.

In Example 4, various examples of the second container will be described. The second container 5B illustrated in FIG. 3 is equipped with a drainage part 5B3 on the entire bottom surface, but as shown in FIG. It is also possible to have a configuration in the lower stage leading to .

The second container 5B (container in which food is placed) has a groove/mesh part for cutting the liquid, a hole larger than the opening of the groove/mesh, and a partial outer frame (only the part that makes up the outer shape). This means that when heating multiple ingredients during simmering, you can separate the ingredients into those that will become hard if overcooked and those that will become softer if simmered for a longer time, and then vary the amount of time they are soaked in liquid (seasoning liquid or broth). becomes.

As an example of this use, for example, the first container 5A and the second container 5B are set, and those with a short simmering time are placed on the left side of the upper or lower tier in FIG. 12, and those with a long simmering time are placed on the left side. One idea is to raise the second container 5B to move it above the liquid level during the first simmering time, and then lower the second container 5B after the second simmering time to move the food into the liquid. It will be done.

In the fifth embodiment, a method will be described in which various states of the heating cooker are notified and the user is informed of the heating state.

The heating cooker of the present invention allows cooking by setting only the first container 5A in the cooking device main body, and also allows cooking with a combination of the first container 5A and the second container 5B. Therefore, both containers are removable. This allows for a variety of cooking methods, including water.

In the case of the present invention, which is used in such a variety of ways, displaying its status is important. These displays and notifications correspond to the container position, for example, such as emitting a notification sound after raising the second container, or notifying the user when the second container is placed in the steaming position. . Further, this positional state may be displayed on the operation panel.
