The lid 12 is, for example, a disk made of syndiotactic polystyrene resin, and is colored dark gray. Fig. 9 is a view taken along the line IX of the lid 12 in Fig. 6. Fig. 10 is a view taken along the line X of Fig. 9. The lid 12 has a large diameter portion 121 and a small diameter portion 122. The small diameter portion 122 has a shape that fits into the opening 111. The lid 12 is provided removably so as to close the opening 111 of the upper pot body 11.

[0014] FIG. 11 is a side view showing the activated carbon filter 13 and the mesh filter 14 installed in the upper pot 1. FIG. 12 is a perspective view of the activated carbon filter 13. The activated carbon filter 13 has a thin plate-like shape and has a filter body 131 and a peripheral protruding portion 132. In the upper pot body 11, the filter body 131 is located in the small diameter portion 115, and the protruding portion 132 abuts against the step portion 1140 (FIG. 8) from above. FIG. 13 is a perspective view of the mesh filter 14. The mesh filter 14 has a shape of a shallow container having an opening 141 that is circular in plan view and opens upward, and a lower half 142 is composed of a mesh net. In the upper pot body 11, the mesh filter 14 is placed on the activated carbon filter 13.

[0015] Fig. 14 is a perspective view of the lower pot 2. The lower pot 2 has a lower pot body 21 and a spout frame 22. Fig. 15 is an exploded perspective view of the lower pot 2. The lower pot body 21 is a bottomed cylindrical body made of, for example, stainless steel or enamel. Fig. 16 is a side view of the lower pot body 21 of Fig. 15. Fig. 17 is a plan view of the lower pot body 21 of Fig. 15. The lower pot body 21 has an opening 211 that is circular in plan view and opens upward, and also has an internal space 212 for storing oil.

[0016] The spout frame 22 is, for example, a member made of syndiotactic polystyrene resin, and is colored dark gray. FIG. 18 is a view of the spout frame 22 in FIG. 15 as seen from the arrow XVIII. FIG. 19 is a view of the spout frame 22 in FIG. 15 as seen from the arrow XIX. FIG. 20 is a view of the spout frame 22 in FIG. 15 as seen from the arrow XX. The spout frame 22 is an annular body removably fitted into the opening 211. The spout frame 22 has a lower frame 221 and an upper frame 222. The lower frame 221 is a portion that fits inside the opening 211. The upper frame 222 is a portion that is exposed from the opening 211.

[0017] Spout frame 22 has two spouts, namely, first spout 223 and second spout 224, protruding radially outward from upper frame 222. First spout 223 and second spout 224 are provided at opposing positions in plan view of upper frame 222. Spout frame 22 has a blocking plate 225 on the inner surface facing second spout 224, which blocks the flow of oil to second spout 224. Blocking plate 225 has a through hole 226 leading to second spout 224. First spout 223 and second spout 224 each have a turng 2231, 2241 at the tip to prevent oil from dripping.

[0018] The lower frame 221 holds an annular seal member 23 on its outer circumferential surface. Fig. 21 is a perspective view of the annular seal member 23. Fig. 22 is a side view of the annular seal member 23. The annular seal member 23 has an outwardly open concave cross-sectional shape. Figs. 23, 24, and 25 show the spout frame 22 with the annular seal member 23 removed, and correspond to the spout frame 22 in Fig. 15, Figs. 18, and 19, respectively. The annular seal member 23 is a rubber member, and is press-fitted into the circumferential groove 227 of the lower frame 221 in a detachable manner.

[0019] The spout frame 22 has a return flow passage 24 for returning the oil that has flowed around to the underside of each of the first spout 223 and the second spout 224 to the internal space 212. The return flow passage 24 is made up of a groove. For example, on the first spout 223 side, the groove is made up of a first groove portion 241 that extends from a position directly below the first spout 223 to both sides in the circumferential direction along the outer circumferential surface of the upper frame portion 222, a second groove portion 242 that extends from the first groove portion 241 further along the outer circumferential surface of the lower frame portion 221, and a third groove portion 243 that descends from the second groove portion 242 through the radial inner side of the annular seal member 23 to communicate with the internal space 212. On the second spout 224 side, the return flow passage 24 is formed in the same manner, that is, it is made up of the first groove portion 241, the second groove portion 242, and the third groove portion 243. It should be noted that the third groove portion 243 is shared by the return flow path 24 on the first spout 223 side and the return flow path 24 on the second spout 224 side.

[0020] Although omitted in the above-mentioned figures, the outer peripheral surface of the lower pot body 21 is covered with a rubber member 25 as shown in Fig. 26. As shown in Fig. 27, the rubber member 25 has a cylindrical shape and is adapted to be fitted onto the lower pot body 21 from below. It is preferable that the surface of the rubber member 25 is subjected to an anti-slip treatment. For example, as shown in Figs. 26 and 27, a large number of grooves 251 are formed, or a surface portion 252 is subjected to a blasting treatment. Other anti-slip treatments may also be adopted.

[0021] FIG. 28 is a front perspective view of the support base 3. FIG. 29 is a front view of the support base 3. FIG. 30 is a right side view of the support base 3. FIG. 31 is a plan view of the support base 3. The support base 3 has an upper support part 31 that supports the upper pot 1 and a lower support part 32 that supports the lower pot 2, which are integral with each other. Specifically, the support base 3 has a form in which the upper support part 31 and the lower support part 32 are supported in parallel by two rear pillar parts 331, 332. As a result, the space between the upper support part 31 and the lower support part 32, i.e., the space in which the lower pot 2 is placed, is open both forward and to the left and right.

[0022] The upper support portion 31 has a through hole 34 into which the upper pot 1 fits. Explaining the through hole 34 with reference to the upper pot body 11 in Fig. 7, as shown in Fig. 28 (or Fig. 31), the through hole 34 has a hole portion 341 into which the opening portion 116 of the upper pot body 11 fits, a surface portion 342 on which the peripheral portion 1151 of the small diameter portion 115 is placed, and a surface portion 343 on which the peripheral portion 1141 of the medium diameter portion 114 is placed, i.e., has a stepped shape.

[0023] The lower support part 32 has a concave part 321 on which the lower pot 2 can be placed so as to slide and fit in from the sideways direction (here, from the front). The concave part 321 has an abutment part 3211 at the rear against which the slid lower pot 2 abuts. The abutment part 3211 is adapted to position the lower pot 2 directly below the through hole 34 of the upper support part 31 by the lower pot 2 abutting against it. Furthermore, the concave part 321 has a plurality of ribs 3212. The multiple ribs 3212 extend in the front-rear direction and parallel to each other.

[0024] The oil purifier 10 is assembled as follows. First, the upper pot 1 and the lower pot 2 are assembled. In the upper pot 1, the mesh filter 13 and the activated carbon filter 14 are placed in the upper pot body 11, and the opening 111 is closed with the lid 12. In the lower pot 2, the spout frame 22 is fitted into the opening 211 of the lower pot body 21. At this time, the lower frame 221 fits into the opening 211, and the upper frame 222 is exposed from the lower pot body 21. Next, the upper pot 1 and the lower pot 2 are placed on the support base 3. That is, in the upper pot 1, the upper pot body 11 is fitted into the through hole 34 of the upper support part 31. In the lower pot 2, the lower pot 2 is slid backward on the concave part 321 until it hits the abutment part 3211. In this way, the oil purifier 10 is assembled.

[0025] The oil purifier 10 configured as above is used as follows. First, the lid 12 of the upper pot 1 is opened. Next, the used oil is slowly poured into the upper pot body 11 from above. The poured oil is purified by removing large impurities with the mesh filter 13, and then removing small impurities with the activated carbon filter 14, and the oil falls into the internal space 212 of the lower pot body 21 and is stored therein. After this, the purified oil may be stored as it is, or may be reused.

[0026] When the purified oil is to be reused, the lower pot 2 is removed from the support stand 3, and the oil is drained from the first spout 223 or the second spout 224. For example, when reusing the oil for stir-frying or grilling, only a small amount of oil is required, so the oil is drained from the second spout 224. When draining the oil from the second spout 224, the oil is temporarily blocked by the shielding plate 225 and passes through the through-hole 226, so that a large amount of oil is prevented from being drained from the second spout 224, and therefore a small amount of oil can be easily reused. On the other hand, when reusing the oil for deep-frying, only a large amount of oil is required, so the oil is drained from the first spout 223.

[0027] Next, the effects of the oil purifier 10 having the above configuration will be described. (1) For example, when oil is discharged from the first spout 223, most of the oil is discharged normally from the first spout 223, but some of the oil flows around to the lower side of the first spout 223. In this state, when the oil discharge is stopped and the oil purifier 10 is placed on a horizontal stand or the like, the oil that flows around to the lower side of the first spout 223 drips down or flows down along the outer circumferential surface of the lower pot body 21 in the conventional oil purifier 10. However, in the oil purifier 10 having the above configuration, as shown in Figures 24 and 25, the oil that flows around to the lower side of the first spout 223 flows through the return flow path 24 and falls into the internal space 212. That is, the oil that flows around to the lower side of the first spout 223 flows through the first groove portion 241, the second groove portion 242, and the third groove portion 243 and falls into the internal space 212. In addition, when oil is discharged from the second spout 224, the oil that has flowed around the lower side of the second spout 224 flows through the first groove 241, the second groove 242, and the third groove 243 and falls into the internal space 212. Therefore, according to the oil purifier 10 having the above configuration, when oil is discharged from the first spout 223 and the second spout 224, the oil that has flowed around the lower side of the first spout 223 and the second spout 224 can be dropped into the internal space 212 through the return flow path 24, so that the oil can be prevented from dripping down or flowing down along the outer circumferential surface of the lower pot body 21. Therefore, the appearance of the oil purifier 10 can be kept clean.

[0028] (2) Since the annular seal member 23 is attached to the circumferential groove 227 of the lower frame portion 221, even if the oil overflows from the return flow passage 24 when the oil flows through the return flow passage 24 as described above, the overflowing oil is blocked by the annular seal member 23 and falls into the internal space 212 through the third groove portion 243. Therefore, the effect of (1) above can be satisfactorily exhibited.

[0029] (3) First spout 223 and second spout 224 have hangers 2231, 2241 at their tips to prevent oil from dripping, which prevents oil from flowing around to the underside of spouts 223, 224. This reduces the amount of oil flowing through return flow path 24, thereby achieving the effect of (1) above.

[0030] (4) When the oil stored in the lower pot 2 is drained for reuse, one of the two spouts 223, 224 can be selected and used according to the type of food to be reused. Therefore, the oil stored in the lower pot 2 can be easily and appropriately reused.

[0031] (5) Since the lower pot body 21 of the lower pot 2 is covered with the rubber member 25, it is possible to prevent a user from being burned by the heat of the oil stored in the lower pot 2 when gripping the lower pot 2. This improves safety.

[0032] (6) The surface of the rubber member 25 is treated to be non-slip, which prevents the user from losing grip of the lower pot 2. This also improves safety.

[0033] (7) In the support base 3, the space in which the lower pot 2 is placed is open to the front, rear, left and right, so the user can easily place the lower pot 2 on the support base 3 without feeling cramped. This improves user convenience.

[0034] (8) Since the upper support portion 31 has the stepped through hole 34, the support base 3 can stably support the upper pot 1. Therefore, used oil can be stably poured into the upper pot 1. This also improves safety.

[0035] (9) Since the lower support portion 32 has the concave portion 321, the lower pot 2 can be slid and placed on the lower support portion 32. Therefore, the lower pot 2 can be easily installed on the support base 3.

[0036] (10) Since the concave surface 321 has a large number of ribs 3212 extending in the front-rear direction, the lower pot 2 can be smoothly slid and placed on the lower support portion 32. Therefore, the lower pot 2 can be easily installed on the support base 3.

[0037] (11) Since the lower support portion 32 has the abutment portion 3211, the lower pot 2 can be easily installed in a position directly below the upper pot 1. This improves user convenience.

[0038] (12) The lid 12 is made of syndiotactic polystyrene resin, and therefore exhibits good heat resistance and durability.

[0039] (13) The cover 12 is colored dark gray, so even if it yellows in sunlight, it is not noticeable. Therefore, a good appearance can be maintained.

[0040] (14) The spout frame 22 is made of syndiotactic polystyrene resin, and therefore exhibits excellent heat resistance and durability.

[0041] (15) The spout frame 22 is colored dark gray, so even if it yellows in sunlight, it is not noticeable. Therefore, a good appearance can be maintained. [Industrial Applicability]

[0042] The oil purifier of the present invention can more reliably solve the problem of oil dripping when the oil is reused, and is therefore of great industrial applicability. [Explanation of symbols]
