The external water receptacle 10 is located below the main body drainage part 50, and the water discharged from the main body drainage part 50 can be stored in the external water receptacle 10. The external water receptacle 10 can be suitably removed with respect to the cooker main body 2, and the user can remove it and treat it, and then reattach it.

FIG. 4 is a schematic structural view showing an outline of a water tank peripheral mechanism.

The water tank 4 is a container for containing water, and includes a water tank housing 4d whose inside is hollow and a water tank lid 4e which can be removed with respect to the water tank housing 4d. A water tank water supply port 4a is provided at the lower part of the tank housing 4d. The upper surface of the water tank housing 4d is open, and the water tank lid 4e covers the opening of the water tank housing 4d. The water tank water supply port 4a is a spring type on-off valve, and is provided with a valve body 4b and a spring 4c. When the water tank 4 is separated from the tank connection portion 20, the valve body 4b is pushed down by the spring 4c to close the water tank water supply port 4a, and when the water tank 4 is connected to the tank connection portion 20, The valve body 4b is pushed up by the valve pressing portion 21 of the tank connection portion 20, and the water tank water supply port 4a is opened.

Since the water tank 4 and the water tank 4 are opened and closed depending on the physical structure, the water tank 4 and the tank connection portion 20 may be easily manufactured but may cause unintended water leakage. That is, when the water tank 4 and the tank connection part 20 are put in and out of contact with each other, the water tank 4 may open halfway and the water in the water tank 4 may leak. By draining such leaked water from the connection drainage port 23, overflow of water from the tank connection portion 20 is prevented.

5 is a side view of the drainage mechanism, FIG. 6 is a perspective view of the drainage mechanism, FIG. 7 is a perspective view of the drainage mechanism in a direction different from that of FIG. 6, and FIG. FIG. 9 is an enlarged cross-sectional view of FIG. 8 taken along arrow CC.

The water receiver 30 has a substantially box shape with an open upper surface, and is disposed below the tank connection 20. That is, the water drained from the connection drainage port 23 of the tank connection portion 20 drips on the bottom surface (water receiving bottom surface 36) of the water receiving portion 30. As described above, by providing the water receiving unit 30 for receiving the water leaking from the tank connection unit 20, it is possible to prevent the water from falling below the water receiving unit 30, and to prevent the electric leakage of the electric component and the like. In addition, by taking measures against water leaks, installation of electric parts etc. becomes possible, and the machine space can be used effectively.

The water receiving bottom surface 36 has a substantially rectangular shape in top view (see FIG. 8), and a water receiving drain 31 opened downward is provided in the vicinity of one corner (lower left in FIG. 8). The water receiving and draining port 31 is a boss extended downward from the water receiving bottom surface 36, and the water receiving and draining port 31 and the draining tube 40 are inserted by inserting the water receiving and draining port 31 into the inside of the draining tube 40. And are connected.

The water receiving bottom surface 36 is inclined such that the water receiving and discharging port 31 is at the lowest position when the heating cooker 1 is placed horizontally. That is, as indicated by the arrow A shown in FIGS. 6 to 8, from the corner (upper right in FIG. 8) located diagonally to the water receiving and discharging port 31, from the angle toward the water receiving and draining 31 side, The water receiving bottom surface 36 is inclined to be low. As described above, by tilting the water receiving bottom surface 36, the received water can be efficiently led to the water receiving and draining port 31. In addition, as for the water receiving bottom surface 36, it is sufficient if the inner side surface (upper surface side) is provided with an inclination, and even if the thickness is changed with respect to the horizontal outer side surface (lower surface side) Good.

A step may be provided in the vicinity of the water receiving / discharging port 31 (the bottom surface step portion 37) of the water receiving bottom surface 36 so as to be lower than the surroundings. The water receiving / discharging port 31 is disposed at the center of the bottom surface step portion 37 in top view, and the bottom surface of the step portion 37 is provided with a slope such that the water receiving / discharging port 31 is the lowest.

A protective rib 35 is provided above the water receiving and draining port 31 so as to cover a part of the water receiving and draining port 31. The protection rib 35 protrudes upward from the water receiving bottom surface 36, and the width in top view is smaller than the diameter of the water receiving drain 31. The protective rib 35 does not completely cover the space above the water receiving and discharging port 31 while partially blocking the space. Therefore, although the flow of water is not blocked by the protection rib 35, it is possible to prevent the foreign matter having a certain size or more from being mixed in the drainage path or blocking the water receiving / discharging port 31 by the foreign matter.

On a side wall near the water receiving and discharging port 31, a water guiding portion 32 cut out so as to be lower than the surrounding is provided. In the present embodiment, the height of the side wall is formed low in the vicinity of the corner on the water receiving and discharging port 31 side. In the side wall corresponding to the water guiding portion 32, the overflowed water may flow easily by chamfering the upper end on the outer surface side. Thus, when the water receiving / discharging port 31 is clogged, water overflowing from the water receiving unit 30 can be guided by the water guiding unit 32 to an intended position.

A water guiding rib 33 is provided on the outer side surface of the outer side surface corresponding to the water guiding portion 32. The water guiding rib 33 is provided along the corner of the side wall on the side of the water receiving and discharging port 31 and extends in the vertical direction. The upper end of the water guide rib 33 is positioned lower than the corresponding side wall. In the water guiding rib 33, the width in the direction orthogonal to the projecting direction changes when the opposing direction on the base end side in contact with the side wall and the projecting end side projecting from the side wall is the projecting direction in top view It has a fan-like shape. Since water overflowing from the water guiding portion 32 easily flows from a projecting portion such as a corner, it is effective to provide the water guiding rib 33 here. When water travels through the water guide rib 33, it is likely to pass through the boundary between the water guide rib 33 and the side wall, that is, the narrowed portion of the proximal end of the water guide rib 33, by surface tension. Thus, a guiding path can be formed so that the water overflowing from the water receiving portion 30 flows along the water guiding rib 33, and it is possible to prevent the water from flowing to an unintended location.

At the lower end of the water guiding rib 33, a return part 34 is provided. The return part 34 is larger in diameter than the water guide rib 33. That is, in the top view, the return part 34 is formed one size larger than the water guiding rib 33. The return part 34 has a flat surface whose surface is in contact with the lower end of the water guiding rib 33, and is inclined so that the side of the drainage tube 40 (the water receiving and draining port 31) is lowered. That is, the return part 34 inclines so that it may become low as it goes to the inside from the outside of the water receiving part 30. As shown in FIG. Accordingly, the water flowing along the water guiding rib 33 can be received by the return portion 34 and guided to flow along the drainage tube 40.

The volume of water in the water receiving portion 30 is preferably set larger than the volume of water in the water tank 4. That is, by increasing the capacity of the water receiving portion 30, even if all the water in the water tank 4 leaks, it can be temporarily received without overflowing from the water receiving portion 30, and the water receiving drainage It can be processed gradually through the mouth 31.

The drainage tube 40 is, for example, a piping member formed of silicon or the like, and the water sent from the water receiving and discharging port 31 is sent to the main body drainage portion 50 through the inside. Further, the water traveling along the outer surface of the drainage tube 40 reaches the main body drainage portion 50 along the drainage tube 40. The drainage tube 40 will be described in detail in a second embodiment described later.

The main body drainage unit 50 drains the water received from the drainage tube 40 to the external water receiver 10. The main body drainage portion 50 will be described in detail in a third embodiment described later.

Second Embodiment
Next, a heating cooker according to a second embodiment of the present invention will be described with reference to the drawings. In addition, in 2nd Embodiment, since it has the general | schematic structure substantially the same as 1st Embodiment, the same code | symbol is attached | subjected and drawing and description are abbreviate | omitted.

FIG. 10: is an expanded sectional view which shows the cross section of the drainage tube in the heating cooker which concerns on 2nd Embodiment of this invention.

In the second embodiment, the drainage tube 40 is provided with a correction rib 41 in addition to the configuration shown in the first embodiment. The correction rib 41 is provided on the outer surface of the drainage tube 40, extends parallel to the main body of the drainage tube 40, and protrudes outward from the outer surface of the drainage tube 40. In the present embodiment, six correction ribs 41 are provided and arranged at equal intervals around the axis of the drainage tube 40, but the number of correction ribs 41 can be set as appropriate. The correction rib 41 corrects the flow of water traveling along the outer surface of the drainage tube 40. Therefore, the flow of water when the correction rib 41 is not provided will be described with reference to a comparative example shown in FIG.

FIG. 11 is a schematic explanatory view showing the flow of water in the comparative example.

In FIG. 11, the comparative example which connected the water receiving part 30 and the main body drainage part 50 with the tube 140 which is not provided with the correction rib 41 is shown. The water W traveling along the outer surface of the tube 140 flows downward from above along the tube 140, but since the flow direction is changed due to various factors, it does not flow straight but travels while rotating in a spiral. Then, when the flow became faster and the momentum became strong, the water W might be separated from the tube 140 and splashed around as shown by the arrow mark B.

In the present embodiment, the correction rib 41 receives the water whose direction is changed, and corrects the water so as to flow along the correction rib 41. In this way, it is possible to correct the flow of water spirally on the outer surface of the drainage tube 40 and prevent the water from splashing.

FIG. 12 is an enlarged cross-sectional view showing a cross section of a modification of the drainage tube.

In the modification, a rib projection 42 is provided on the correction rib 41, and the rib projection 42 extends around the axis of the drainage tube 40 from the tip of the correction rib 41. Although FIG. 12 shows a structure in which the rib projection 42 extends in both directions around the axis (for example, in the upper correction rib 41 in the left-right direction), the present invention is not limited thereto. It is good also as a structure extended to one side. That is, the provision of the rib projection 42 formed wider than the correction rib 41 prevents water from being transmitted to the outside of the correction rib 41.

Third Embodiment
Next, a heating cooker according to a third embodiment of the present invention will be described with reference to the drawings. In the third embodiment, the general structure is substantially the same as that of the first embodiment and the second embodiment, so the same reference numerals are given and the drawings and the description are omitted.

FIG. 13: is an expanded sectional view which shows the cross section of the main body drainage part in the heating cooker which concerns on 3rd Embodiment of this invention.

In the third embodiment, in addition to the configuration shown in the first embodiment, the main body drainage portion 50 has a feature. Concretely, the main body drainage part 50 is formed in the box shape which upper direction opened, and the inner side drainage port 51 opened downward is provided in the center of the bottom face. The inner drainage port 51 is formed by opening the center of the inner boss 51 a which is extended upward from the bottom surface of the main body drainage portion 50. The inner boss 51 a is connected to the drainage tube 40 so as to be inserted into the drainage tube 40. Therefore, water passing through the inside of the drainage tube 40 is drained from the inner drainage port 51.

In the bottom surface of the main body drainage portion 50, an outer drainage port 52 is further provided by opening a part of the outer periphery of the inner boss 51a. The outer drainage port 52 is provided so as to open a range including the outer side of the drainage tube 40 in a top view, and drains the water transmitted along the outer surface of the drainage tube 40.

The outer side of the outer drainage port 52 is an outer water receptacle 53 which receives the water flowing along the outer surface of the drainage tube 40. As described above, by considering not only the water sent through the inside of the drainage tube 40 but also the water transmitted along the outer surface of the drainage tube 40, it is possible to secure the safety against electric leakage and the like. Further, since the water can be temporarily stored also in the main body drainage portion 50, it is possible to prevent the overflow when the water sent is increased.

The main body drainage portion 50 is not limited to this, and a plate portion having a hole for screwing to the cooking device main body portion 2 may be provided.

The embodiment disclosed this time is an example in all points, and it is not a basis for a limited interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-mentioned embodiment, and is defined based on the statement of a claim. Moreover, all the changes within the meaning and range equivalent to a claim are included.
