Description

  The present invention relates to a heating cooker that copes with water droplets generated when food is heated and cooked, and water droplets falling outside through a gap at a joint portion such as a door.

  In general, water vapor is generated when food is cooked based on heating means such as an electric heater or magnetron (high frequency), and this condensates and falls from the front opening of the heating chamber through the gap between the door and the outside of the main body. There is sorrow to do. In addition, in recent years, heating cookers equipped with so-called steam supply means that heat water and supply steam into the heating chamber to enable cooking are becoming widespread, but condensation is more likely to occur in the heating chamber. The situation tends to cause water droplets to leak out of the body.

  Therefore, as a countermeasure against dripping of water droplets to the outside, a water drop receiving portion (drain container) is detachably installed below the door, and in the configuration having the water vapor supply means, the water supplied to the water vapor supply means A configuration has been proposed in which a water tank (water storage container) that stores water is detachably disposed through a water droplet receiver (see, for example, Patent Document 1).

Japanese Patent No. 3966331

  However, in the above configuration, of course, the water droplet receiving portion must be installed corresponding to the portion where the water droplets are dripped, and there is a concern that the size of the water droplet receiving portion will be increased, particularly a long shape on the left and right. It is not easy to design and manufacture because the opening shape of the receiving portion needs to be large. Moreover, according to the said structure (patent document 1) of the water tank which comprises a water vapor | steam supply means, in the location where the water tank of the water droplet receiving part penetrated, a water reservoir recessed part becomes small (a shallow bottom face is comprised). Therefore, the water droplets stored on this shallow bottom surface due to the action of surface tension, etc. are likely to spill on the floor surface when removing the water droplet receiving part, and the overall configuration requires a large opening shape as described above and is long in the left and right directions. Then, there is a practical problem such that water stored during an operation such as removing the water drop receiving portion is likely to spill.

  In order to solve the above-mentioned problems, the present invention reliably receives water droplets leaking out of the main body, and can store a sufficient amount of water as compared with the prior art, and measures against water droplets such as the stored water is not easily spilled. An object is to provide a cooker that has been applied.

The right-side water receiving portion 26b connected to the rear-side water receiving portion 26c has an opening 26d formed at one end thereof so as to face the upper surface of the drain container 15.

  As shown in FIG. 3 and FIG. 9 to be described later, a third water receiving portion 27 is formed at the lower end portion of the hot air casing 17 at a position below the joint portion between the back wall 2a and the bottom wall 2e of the heating chamber 2. Has been. As shown in FIG. 5, which will be described later, the third water receiving portion 27 extends to a position where both left and right end portions face the left and right water receiving portions 26a and 26b of the second water receiving portion 26, and has a recessed section shape. Is formed. Further, as shown in FIG. 4, a fourth water receiving portion 28 having a concave cross-section with a rib 23 as one side wall is integrally formed in the water receiving case 14 at the rear of the storage space of the water storage container 13. One end of the fourth water receiving portion 28 is connected to the front side in the front-rear direction of the left water receiving portion 26a of the second water receiving portion 26 and is slightly connected to the front, and the other end is opened to open the upper surface of the drain container 15. The arrangement is such that the opening 28a is formed. The water receiver 28 has a bottom surface that is inclined downward to reach the lowest opening 28a.

  FIG. 5 is a plan view schematically showing mainly the arrangement configuration of each of the water receiving portions 25 to 28 and the drain container 15, and further in FIG. 5, the flow of water flowing through each of the water receiving portions 25 to 28 is indicated by arrows. A to H are shown schematically. With reference to FIG. 5, the flow of water in the water receivers 25 to 28 will be described. The bottom surface of the left water receiving portion 26a of the second water receiving portion 26 is formed in a gentle V-shape that is in the front-rear direction and is inclined downward toward the communication portion 28b with the fourth water receiving portion 28. ing. In addition, the water flowing through the second water receiving portion 26 and the right water receiving portion 26b shown in FIG. 5 is inclined downward in the directions indicated by arrows F and E.

  Arrow A indicates the flow of water such as water droplets flowing down the first water receiving portion 25, arrow B indicates the flow of water flowing down the first inclined portion 27b of the third water receiving portion 27, and arrow C indicates The flow of water flowing down the second inclined portion 27c of the third water receiving portion 27 is shown. Arrow D receives water flowing down the first inclined portion 27b of the third water receiving portion 27 indicated by arrow B, and this indicates the flow of water toward the communication portion 28b. Arrow E indicates the flow of both water flowing down the rear water receiving portion 26c of the second water receiving portion 26 indicated by arrow F and water indicated by arrow C. The arrow G indicates the flow of water that leaks and drops from the left end of the gap L (see FIG. 6) at the joint portion between the door 4 and the front frame portion 5. Arrow H indicates the flow of both water indicated by arrow D and arrow G, and both flow down along the slope of the bottom surface.

Next, with reference to FIG. 6 to FIG. 8, the water droplet countermeasure means of this embodiment applied to the lower front of the main body 1 will be specifically described.
FIG. 6 is a side view of the heating cooker partially cut along the X1-X1 line in FIG. 1, and FIG. 7 is an enlarged perspective view showing a part of the water receiver 25 at the lower part of the main body 1. FIG. 8 is a side view of the heating cooker shown partially cut along line X2-X2 in FIG.

  As clearly shown in FIGS. 6 to 8, the first upper portion of the water storage container 13 is located below the joint between the front frame 5 around the opening 3, which is the front surface of the heating chamber 2, and the rear side of the door 4. It is set as the structure which provided the water receiving part 25 (refer especially FIG. 6). The first water receiving portion 25 is directed to the drain container 15 disposed adjacent to the water storage container 13 after receiving the water droplet W leaked and dropped from the gap L at the joint portion between the door 4 and the front frame part 5. It has a function of guiding the water droplets to flow down (see arrow A in FIG. 5 and FIG. 7).

  However, the first water receiving portion 25 is long in the left-right direction and the cross-sectional shape in the front-rear direction forms a concave shape (shown as a concave portion 29 in the figure), and the end of the first water receiving portion 25 on the drain container 15 side is The opening 25a is narrowed in the front-rear direction while maintaining the shape of the recess, and the other end is connected to the left water receiving portion 26a of the second water receiving portion 26 as described above. The bottom surface of the first water receiving portion 25 is mainly formed in a shape that is inclined downward toward the drain container 15 in the left-right direction. Further, the length dimension of the first water receiving portion 25 extending in the left-right direction may be equal to or greater than the left-right width dimension of the water storage container 13, and the width dimension (front-rear direction) of the recess 29 is the same as that of the door 4. The width dimension is suitable for receiving a water droplet W that leaks and drops from the gap L with the front frame portion 5.

  A part of the water droplets leaked and dropped from the left end of the gap L at the joint portion between the door 4 and the front frame portion 5 is the left water receiving portion of the second water receiving portion 26 communicating with the first water receiving portion 25. It is received by 26a and flows down (indicated by an arrow G in FIG. 5), and is guided to the drain container 15 through a communicating fourth water receiving portion 28 (indicated by an arrow H in FIG. 5).

  In contrast to the first water receiver 25 having the above-described configuration, the drain container 15 is made of resin, for example, has a rectangular bottomed container shape with an open upper surface, and the first water receiver 25 is opened toward the upper surface opening. The opening 25a is disposed, and the open ports 26d and 28a of the second and fourth water receiving portions 26 and 28 are also disposed in the same manner. As a result, the drain container 15 collects and stores the water droplets guided to the water receiving portions 25, 26, and 28, and the water droplets leaked and dropped from the gap L at the joint portion between the door 4 and the front frame portion 5. It has a function of receiving and storing W directly (see FIG. 8). Therefore, most of the water droplets W leaked and dropped from the gap L at the joint portion between the door 4 and the front frame portion 5 are received by the first water receiving portion 25 and the direct drain container 15. A part of the water droplets leaking out from the left end of the gap L is received by the left water receiving portion 26a of the second water receiving portion 26 (indicated by an arrow G in FIG. 5).

  On the other hand, FIG. 1, FIG. 4 and FIG. 6 show a water storage container 13 that constitutes the water vapor generating device 9 described above, but the bottom surface of the water storage container 13 is a bottom plate (not shown) of the water receiving case 14. The water receiving case 14 is supported so as to be detachable, and a water stop cock (not shown) is provided on the back surface thereof. Accordingly, by mounting the water storage container 13 at a predetermined position of the water receiving case 14, the water stop cock is opened, and the water storage container 13 can be connected in fluid-tight communication with a pump device (not shown). It is possible to supply the water vapor generating unit 10 by driving the pump device.

Next, with reference to FIGS. 9 and 10, the water droplet countermeasure means of the present embodiment applied to the lower rear portion of the main body 1 will be described in detail.
9 is an enlarged cross-sectional view of the lower portion of the hot air casing 17 shown in FIG. 3, and FIG. 10 is a vertical side view cut along the line X3-X3 in FIG.

  3 and FIG. 5 will be further described below. A third water receiving portion is provided below the joint portion 30a between the bottom wall portion 2g of the bottom wall 2e of the heating chamber 2 and the back wall 2a. 27 is provided. As shown in FIGS. 3 and 9, the third water receiving portion 27 is formed by forming a lower end portion extending below the hot air casing 17 into a concave shape in cross section by sheet metal bending. In this case, a joint 30b is also formed between the hot air casing 17 and the screwed back wall 2a.

  Therefore, for example, when water droplets W adhere to the back wall 2a of the heating chamber 2, the water droplets W drop downward from a gap generated at the joint 30a between the bottom plate 2g of the bottom wall 2e of the heating chamber 2 and the back wall 2a. Moreover, the case where the water droplet W adheres in the hot-air casing 17 is also considered, and the water droplet W in this case is dripped below from the clearance gap produced in the junction part 30b. Then, any water droplet W is received by the third water receiver 27.

  However, the third water receiving portion 27 is long in the left-right direction and has a cross-sectional shape in the front-rear direction forming a concave shape (shown as a concave portion 31 in FIG. 9), and the left and right end portions are recessed, and the opening 27a is described later. The main body bottom plate 32 is disposed so as to face the rectangular holes 33 formed on both the left and right sides, and has a communication structure with the second water receiving portion 26 (see FIG. 10). The top portion 27 d of the bottom surface of the third water receiving portion 27 is located slightly on the left side from the center in the left-right direction of the main body 1. The third water receiving portion 27 includes a first inclined portion 27b having a shape that slopes downward from the top portion 27d having the highest bottom portion toward the upper portion of the left water receiving portion 26a, and a right water receiving portion to the right from the top portion 27d. It is comprised by the 2nd inclination part 27c of the shape inclined downward toward the upper part of the part 26b (refer FIG. 5).

  Further, the lateral length of the third water receiving portion 27 extending in the left-right direction is equal to or greater than the left-right width size of the joint portions 30a and 30b, and the width dimension (front-rear direction) of the recess 31 is joined. The width dimension is suitable for receiving a water droplet W that leaks and drops from the gaps generated in the portions 30a and 30b (see FIG. 9).

  As shown in FIG. 10, the main body bottom plate 32 is a plate-like member that closes the bottom of the main body 1 and is attached to the bottom of the main body 1 so as to cover the upper portion of the second water receiving portion 26 of the water receiving case 14. Has been. Open ports 27 a at both left and right ends of the third water receiving portion 27 formed at the lower end portion of the hot air casing 17 are arranged slightly above the main body bottom plate 32. Thus, the rectangular holes 33 formed on the left and right sides of the main body bottom plate 32 are located above the left and right water receiving portions 26a and 26b of the second water receiving portion 26, and correspond to the opening 27a. Set to Thus, the water (shown by arrows B and C in FIG. 5) that drops and flows down from the joint portions 30a and 30b onto the third water receiving portion 27 drops from the opening 27a and passes through the rectangular hole 33. Therefore, the third water receiving portion 27 and the second water receiving portion 26 are substantially in communication with each other. Thereafter, the water is guided to the drain vessel 15 through the second water receiving portion 26 (indicated by arrows D, E, and H in FIG. 5).

  Next, the water droplet countermeasure means provided at the lower rear part of the main body 1 will be described mainly with reference to FIG. 3, FIG. 5, and FIG. The rear water receiving portion 26c of the second water receiving portion 26 is disposed below the back plate (rear wall) 34a of the outer box 34 that forms the outline of the main body 1 (see FIG. 10). The rear water receiving portion 26c receives the water droplet W that has dropped on the back plate 34a of the outer box 34, and then flows down the rear water receiving portion 26c to the right (indicated by an arrow F in FIG. 5). It is guided to the right side water receiving portion 26b (indicated by an arrow E in FIG. 5), and flows into the drain container 15 and is stored.

  However, the rear water receiving portion 26c of the second water receiving portion 26 is long in the left-right direction and has a cross-sectional shape in the front-rear direction formed in a concave shape (shown as a concave portion 35 in FIG. 10). As shown in FIG. 10, the rear water receiving portion 26 c has a width dimension suitable for receiving the water droplets W dripping from the back plate 34 a of the outer box 34 as the width dimension (front-rear direction) of the recess 35. For this reason, the rear water receiving portion 26 c protrudes slightly rearward from the back plate 34 a of the outer box 34.

  Note that the water droplet countermeasure means below the left and right side portions of the main body 1 in this embodiment is not particularly provided. For example, the width dimension of the cross-sectional shape in the left and right direction of the left and right side water receiving portions 26a and 26b of the second water receiving portion 26 The right and left side water receiving portions 26a and 26b are protruded slightly outward from the left and right side plates of the outer box 34 so that water drops dripping from the left and right side plates of the outer box 34 are received. The receiving portions 26a and 26b can receive water droplets dripping from the left and right side surfaces of the outer box 34, and it is also possible to easily apply water droplet countermeasure means below the left and right side portions of the main body 1.

Next, the operation of the cooking device configured as described above will be described.
When the food stored in the heating chamber 2 is condensed by moisture or the like evaporated when performing cooking by high frequency heating or heater heating, water droplets are generated from the opening 3 and the door 4 and the front frame 5 It leaks through the gap L at the joining portion and drops down outside the main body 1. In particular, in steam cooking in which steam is supplied to the heating chamber 2 using the water vapor generating device 9, a larger amount of water droplets are generated. However, the first water receiving portion 25 having the concave portion 29 is fixedly provided immediately below the dripping, and the water droplet W dripping from the opening 3 by the drain container 15 together with the first water receiving portion 25 is always received reliably. be able to.

  On the other hand, when water droplets W adhering in the inner wall 2a of the heating chamber 2 and the hot air casing 17 are dropped from the gap formed in the joint portion 30a and the joint portion 30b, the third water formed in the lower end portion of the hot air casing 17 The receiving part 27 can always receive it reliably. In addition, water droplets W may be generated on the back plate 34a of the outer box 34 based on a temperature difference or the like. Even if the water droplets W drop, the rear water receiving portion 26c of the second water receiving portion 26 always ensures the water drops. I can receive it. These water droplets W are guided to the drain container 15 in front through the second water receiving portion 26 and the fourth water receiving portion 28.

  The water storage container 13 and the drain container 15 that are detachably adjacent to the water receiving case 14 at the bottom of the main body 1 are attached and detached as needed. That is, the water storage container 13 is attached / detached when the water necessary for steam cooking is supplied, while the drain container 15 is attached / detached when the water storing the water droplets is discarded. In this case, the first to fourth water receivers 25 to 28 are formed around the storage container 13 and the drain container 15, but these are integrally formed and fixed with the water receiver case 14. The attaching / detaching operation of each of the containers 13 and 15 can be performed smoothly and without spilling water.

According to the said Example, there exist the following effects.
The water storage container 13 and the drain container 15 are detachably adjacently arranged so as to be divided into left and right parts on the front side of the lower part of the main body 1 when the main body 1 is viewed from the front. For this reason, since the drain container 15 does not have a long shape on the left and right, there is no possibility that the water stored during the attachment / detachment operation such as removing the drain container 15 from the main body 1 will be spilled.

  Further, the water droplet W leaking and dropping from the opening 3 of the heating chamber 2 through the gap L of the joint portion between the door 4 and the front frame portion 5 is received by the first water receiving portion 25 and the drain container 15, It can be stored in the container 15 and does not leak to the outside such as the installation surface. In this embodiment, a part of the water droplets from the gap L on the left corner side is surely received by the left water receiving portion 26a of the second water receiving portion, but this is the first water receiving portion. It is also possible to easily adopt a structure in which 25 is extended to the left end side and received by the first water receiving portion 25.

  The water droplets W generated and dropped on the back plate 34 a of the outer box 34 can be reliably received by the rear water receiving portion 26 c of the second water receiving portion 26. For this reason, a water droplet does not fall to the exterior lower part of the main body 1, and there is no worry of getting the installation surface wet. In this case, it is good also as a structure which receives a water droplet in the 2nd water receiving part 26 also with respect to the left and right side plates of the outer case 34.

  The water receiving portions 25 to 28 and the storage portions of the water storage container 13 and the drain container 15 are formed integrally with the water receiving case 14. For this reason, these can be assembled easily and inexpensively.

  The water droplet W dripping from the gap formed at the joint 30a between the back wall 2a and the bottom wall 2e of the heating chamber 2 is reliably received by the third water receiving portion 27 formed at the lower end portion of the hot air casing 17, The water droplet W is guided to the drain container 15 through the second water receiving portion 26 communicating with the third water receiving portion 27. For this reason, a water droplet does not fall to the exterior lower part of the main body 1, and there is no worry of getting the installation surface wet.

  Further, condensation may occur in the hot air casing 17, and in this case, water droplets W are dropped from a gap generated at the joint portion 30 b between the inner wall 2 a adjacent to the joint portion 30 a and the peripheral portion of the hot air casing 17. However, the water droplet W is reliably received by the third water receiving portion 27 formed integrally with the lower end portion of the hot air casing 17, and the water droplet communicates with the third water receiving portion 27 in the same manner as described above. It is led to the drain vessel 15 through the water receiving portion 26. For this reason, a water droplet does not fall to the exterior lower part of the main body 1, and there is no worry of getting the installation surface wet. In this case, the joining portion 30b may be sealed with a sealing member such as silicon. It is also effective in the case of dripping water drops due to deterioration during use.

  In addition, this invention is not limited to an above-described Example, It can implement suitably by changing in the range which does not deviate from the summary of this invention. For example, in the above embodiment, the electric heater 8, the steam generator 9 and the hot air circulation unit 16 are provided on the ceiling wall 2d, the left side wall 2b and the back wall 2a of the heating chamber 2, respectively. May be provided on the other side wall of the heating chamber 2. Moreover, although the drain container 15 was made into the form which opened the upper surface, you may make it the structure with a lid | cover which can be opened and closed except the part into which dripping water flows.
