Description

Technical Field

[0001] The utility model relates to kitchen appliances, in particular to a frying and roasting machine. Background Art

[0002] The grilling machine in the prior art usually includes an upper grilling plate assembly and a lower grilling plate assembly. The lower grilling plate assembly includes a lower shell, a lower grilling plate, a power cord and a junction box. The junction box is arranged on the lower shell. The forked end of the power cord is arranged in the junction box. The junction box is provided with a lead hole for the power cord to be led out and a wiring hole for the forked end of the power cord to be inserted into the grilling machine. The heat inside the grilling machine will enter the junction box through the wiring hole, and the temperature inside the junction box will rise. In order to prevent the forked end of the power cord from being overheated and causing safety hazards, the prior art generally adds heat insulation materials to the forked end of the power cord. For example, the utility model patent CN207399525U discloses that the accommodating cavity of the junction box is filled with heat insulation cotton. The grilling machine is usually used in a humid environment such as a kitchen. Although the heat insulation cotton has a good heat insulation effect, it absorbs moisture in the air. When the grilling machine is working, the temperature inside the junction box rises, and the moisture absorbed by the heat insulation cotton turns into water vapor. The water vapor contacts the forked end of the power cord and causes short circuit, leakage, etc., which poses a safety hazard. Utility Model Content

[0003] The utility model aims to provide a grilling machine, which overcomes the shortcomings of the prior art, reduces the temperature rise of the forked end of the power cord and avoids safety hazards.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a grilling machine, comprising an upper grilling pan assembly and a lower grilling pan assembly, the lower grilling pan assembly comprising a lower shell, a lower grilling pan, a power cord and a junction box, the junction box being arranged on the lower shell, the forked end of the power cord being arranged in the junction box, the junction box being provided with a lead hole for leading out the power cord and a wiring hole for the forked end of the power cord to penetrate into the grilling machine, the junction box being provided with a heat insulation board for dividing the junction box into a first chamber and a second chamber, the wiring hole being located in the first chamber, the lead hole and at least part of the forked end of the power cord being located in the second chamber.

[0005] After adopting the above technical scheme, the utility model has the following advantages: the junction box is separated into a first chamber and a second chamber by a heat insulation board, the lead hole and at least part of the forked end of the power cord are located in the second chamber, and the wiring hole is located in the first chamber, which reduces the air convection in the internal space of the junction box, and limits the high temperature area in the wiring hole in the junction box to the first chamber. The heat insulation board effectively blocks the heat in the first chamber from flowing to the second chamber, which can effectively reduce the temperature rise of the second chamber, ensure that the ambient temperature of the forked end of the power cord meets its normal working requirements, effectively avoid the temperature of the forked end of the power cord is too high, and can also avoid water vapor from contacting the forked end of the power cord to cause short circuit, leakage, etc., so that the product meets safety requirements and avoids safety hazards.

[0006] Furthermore, the second chamber is provided with a housing chamber for accommodating the forked end of the power cord, the housing chamber is provided on a side of the second chamber away from the heat insulation board, and a first heat insulation gap is provided between the chamber wall of the housing chamber and the heat insulation board. Using the above technical solution, the second chamber is provided with a housing chamber for accommodating the forked end of the power cord, the housing chamber is provided on a side of the second chamber away from the heat insulation board, and a heat insulation gap is provided between the chamber wall of the housing chamber and the heat insulation board. The heat insulation board, the first heat insulation gap and the chamber wall of the housing chamber all play a role in preventing the heat in the first chamber from being transferred to the forked end of the power cord, playing a multiple heat insulation role, and further reducing the temperature of the forked end of the power cord and the environment in which it is located.

[0007] Furthermore, the junction box includes a box body and a box cover, and the box cover is provided with a first barrier rib adapted to the shape of the heat insulation board and a second barrier rib adapted to the shape of the cavity wall of the accommodating cavity. When the box cover covers the box body, the first barrier rib and the heat insulation board are offset in the height direction and at least partially overlapped, and the second barrier rib and the cavity wall of the accommodating cavity are offset in the height direction and at least partially overlapped. With the above-mentioned technical solution, the first barrier rib and the heat insulation board are offset in the height direction and at least partially overlapped, which increases the sealing between the first barrier rib and the heat insulation board, further limits the air convection between the first chamber and the second chamber, thereby further reducing the heat flow from the first chamber to the second chamber, reducing the temperature rise of the first chamber, and the second barrier rib and the cavity wall of the accommodating cavity are offset in the height direction and at least partially overlapped, which can also increase the sealing between the second barrier rib and the cavity wall of the accommodating cavity, further limit the air convection between the accommodating cavity and the second chamber, thereby further reducing the heat flow from the second chamber to the accommodating cavity, reducing the temperature rise of the accommodating cavity, and further effectively avoiding the temperature of the forked end of the power cord from being too high.

[0008] Furthermore, the overlapping length of the first baffle and the heat insulation board in the height direction is L1, L1 ≥ 3mm, and the overlapping length of the second baffle and the cavity wall of the accommodating cavity in the height direction is L2, L2 ≥ 3mm. Through the above technical solution, if L1 < 3mm, the sealing effect between the first baffle and the heat insulation board is poor, the air in the first cavity is easy to flow to the second cavity, and the temperature rise of the second cavity is fast; and, if L2 < 3mm, the sealing effect between the second baffle and the cavity wall of the accommodating cavity is poor, the air in the second cavity is easy to flow to the accommodating cavity, and the temperature rise of the accommodating cavity is fast.

[0009] Furthermore, the first barrier rib and at least a portion of the second barrier rib are located in the first insulation gap. Through the above technical solution, the first barrier rib and at least a portion of the second barrier rib are located in the first insulation gap, which forms a blocking effect on the air circulation in the first insulation gap, thereby further slowing down the heat transfer from the first chamber to the second chamber.

[0010] Furthermore, there is a second heat-insulating gap between the first barrier rib and the second barrier rib. Through the above technical solution, the second heat-insulating gap, the first barrier rib and the second barrier rib play a multiple heat-insulating role, thereby further reducing the heat transfer from the first chamber to the second chamber.

[0011] Furthermore, the inner wall of the second chamber is provided with a protruding annular rib, and the annular rib and the inner wall of the second chamber are combined to form a receiving chamber. With the above technical solution, the inner wall of the second chamber is provided with a protruding annular rib, and the annular rib and the inner wall of the second chamber are combined to form a receiving chamber, and the sealing performance of the receiving chamber is better.

[0012] Furthermore, the junction box further comprises a receiving box detachably connected to the inner wall of the second chamber, and a receiving chamber is provided in the receiving box. With the above technical solution, the receiving box is detachably connected to the inner wall of the second chamber. On the one hand, later maintenance only requires replacement of the damaged receiving box, without replacing the entire junction box, which is more cost-effective. On the other hand, there is no need to first install the forked end of the power cord into the receiving box and then install the receiving box in the junction box, which avoids installing the forked end of the power cord in a small space in the junction box, making assembly more convenient.

[0013] Furthermore, a positioning structure cooperating with the receiving box is provided in the second chamber. With the above technical solution, by providing the positioning structure, the installation position of the receiving box is made more accurate, thereby making the routing of the forked end of the power cord more reasonable.

[0014] Furthermore, the opening direction of the wiring hole is staggered with the insulation board. By adopting the above technical solution, the air in the wiring hole is effectively prevented from directly blowing on the insulation board, which is beneficial to reducing the temperature rise of the insulation board.

[0028] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0029] like Figures 1 to 5 As shown, the utility model provides a grilling machine, comprising an upper grilling pan assembly and a lower grilling pan assembly, the upper grilling pan assembly comprising an upper shell 10 and an upper grilling pan 11, the lower grilling pan assembly comprising a lower shell 20, a lower grilling pan 21, a power cord 30 and a junction box 40, the junction box 40 is arranged on the lower shell 20, the forked end 31 of the power cord 30 is arranged in the junction box 40, the junction box 40 is provided with a lead hole 404 for leading out the power cord 30 and a wiring hole 405 for the forked end 31 of the power cord 30 to penetrate into the grilling machine, the junction box 40 is provided with a heat insulation board 403 for dividing the junction box 40 into a first chamber 401 and a second chamber 402, the wiring hole 405 is located in the first chamber 401, the lead hole 404 and at least part of the forked end 31 of the power cord 30 are located in the second chamber 402.

[0030] A heating element is also provided inside the grilling machine. The heat generated by the heating element is transferred to the food through the upper grilling plate 11 and the lower grilling plate 21 attached thereto, thereby baking the food. The heat inside the grilling machine enters the junction box 40 through the wiring hole 405.

[0031] It should be noted that the heating element can be a heating tube, a heating plate or other structures.

[0032] To this end, in order to avoid safety hazards caused by the forked end 31 of the power cord 30 being too high, a heat insulation board 403 is provided in the junction box 40 to separate the junction box 40 into a first chamber 401 and a second chamber 402. The wiring hole 405 is located in the first chamber 401, and the lead hole 404 and at least part of the forked end 31 of the power cord 30 are located in the second chamber 402, thereby reducing air convection in the internal space of the junction box 40 and limiting the high temperature area of ​​the junction box 40 located in the wiring hole 405 to the first chamber 401. The heat insulation board 403 effectively blocks the heat in the first chamber 401 from flowing to the second chamber 402, which can effectively reduce the temperature rise of the second chamber 402, ensure that the ambient temperature of the forked end 31 of the power cord 30 meets its normal working requirements, effectively avoid the temperature of the forked end 31 of the power cord 30 being too high, and also avoid water vapor from contacting the forked end 31 of the power cord 30 to cause short circuit, leakage, etc., so that the product meets safety regulations and avoids safety hazards.

[0033] It should be noted that the heat insulation board 403 is a hydrophobic, insulating plastic part. The heat insulation board 403 can be integrally formed with the junction box 40 to reduce accessories and facilitate assembly. It can also be detachably connected to the junction box 40. When the grilling machine is used in a hot and humid environment for a long time, the heat insulation board 403 will not absorb moisture in the environment, ensuring the safety of use of the forked end 31 of the power cord 30.

[0034] In order to further reduce the temperature rise of the heat insulation board 403, the opening direction of the wiring hole 405 is staggered from the heat insulation board 403. Such a design effectively prevents the air from the wiring hole 405 from blowing directly onto the heat insulation board 403, which is beneficial to reducing the temperature rise of the heat insulation board 403, thereby reducing the heat transfer into the second chamber 402.

[0035] In order to further reduce the temperature rise in the first chamber 401, a housing chamber 406 for housing the bifurcated end 31 of the power cord 30 is provided in the second chamber 402. The housing chamber 406 is provided on a side of the second chamber 402 away from the heat insulation board 403, and a first heat insulation gap 407 is provided between the chamber wall of the housing chamber 406 and the heat insulation board 403. With such a design, the heat insulation board 403, the first heat insulation gap 407 and the chamber wall of the housing chamber 406 all play a role in preventing the heat in the first chamber 401 from being transferred to the bifurcated end 31 of the power cord 30, playing a multiple heat insulation role, and further reducing the bifurcated end 31 of the power cord 30 and the ambient temperature thereof.

[0036] Specifically, the inner wall of the second chamber 402 is provided with a protruding annular rib 410, which encloses the inner wall of the second chamber 402 to form a receiving chamber 406. With such a design and an integral injection molding structure, the receiving chamber 406 has better sealing performance, and can also reduce assembly steps, making assembly easier.

[0037] In this embodiment, the junction box 40 includes a box body 408 and a box cover 409. When the box cover 409 covers the box body 408, a matching gap is provided between the box cover 409 and the heat insulation board 403 and the cavity wall of the accommodating cavity 406. The air in the first chamber 401 can easily enter the accommodating cavity 406 through the matching gap. For this purpose, the box cover 409 is provided with a first retaining rib 412 adapted to the shape of the heat insulation board 403 and a second retaining rib 413 adapted to the shape of the cavity wall of the accommodating cavity 406. When the box cover 409 covers the box body 408, the first retaining rib 412 and the heat insulation board 403 are staggered in the height direction and at least partially overlapped, thereby increasing the sealing between the first retaining rib 412 and the heat insulation board 403. The air convection between the first chamber 401 and the second chamber 402 is further restricted, thereby further reducing the heat flow from the first chamber 401 to the second chamber 402, reducing the temperature rise of the first chamber 401, and the second retaining rib 413 and the cavity wall of the accommodating cavity 406 are offset and at least partially overlapped in the height direction, which can also increase the sealing between the second retaining rib 413 and the cavity wall of the accommodating cavity 406, further restricting the air convection between the accommodating cavity 406 and the second chamber 402, thereby further reducing the heat flow from the second chamber 402 to the accommodating cavity 406, reducing the temperature rise of the accommodating cavity 406, and further effectively avoiding the temperature of the forked end 31 of the power cord 30 being too high.

[0038] It should be noted that screw columns may be provided on the box cover 409 and the box body 408. When the box cover 409 covers the box body 408, the screw columns on the box cover 409 and the screw columns on the box body 408 are aligned for screw connection.

[0039] In order to improve the sealing effect, the overlapping length of the first barrier rib 412 and the heat insulation board 403 in the height direction is L1, L1 ≥ 3mm, and the overlapping length of the second barrier rib 413 and the cavity wall of the accommodating cavity 406 in the height direction is L2, L2 ≥ 3mm. If L1 < 3mm, the sealing effect of the first barrier rib 412 and the heat insulation board 403 is poor, the air in the first cavity 401 is easy to flow to the second cavity 402, and the temperature rise of the second cavity 402 is fast; and, if L2 < 3mm, the sealing effect of the second barrier rib 413 and the cavity wall of the accommodating cavity 406 is poor, the air in the second cavity 402 is easy to flow to the accommodating cavity 406, and the temperature rise of the accommodating cavity 406 is fast. For this reason, in this embodiment, preferably, L1 = 5mm, L2 = 5mm, increase the overlapping length, and further limit the air circulation. Of course, L1 can also be a suitable value such as 3mm, 4mm, 6mm, 7mm, etc., and L2 can also be a suitable value such as 3mm, 4mm, 6mm, 7mm, etc.

[0040] In order to further improve the heat insulation effect, a second heat insulation gap 414 is provided between the first barrier rib 412 and the second barrier rib 413. With such a design, multiple heat insulation effects are achieved through the second heat insulation gap 414, the first barrier rib 412 and the second barrier rib 413, thereby further reducing the heat transfer from the first chamber 401 to the second chamber 402.

[0041] Furthermore, since the first thermal insulation gap 407 lacks a barrier structure, air circulates faster in the first thermal insulation gap 407, and for this reason, the first barrier rib 412 and at least part of the second barrier rib 413 are located in the first thermal insulation gap 407. This design forms a barrier effect on the air circulation in the first thermal insulation gap 407, thereby further slowing down the heat transfer from the first chamber 401 to the second chamber 402.

[0042] It is understandable that in other embodiments of the present invention, the first barrier rib may also be located in the first chamber, and the second barrier rib may be located in the second chamber, so as to ensure the size of the first thermal insulation gap and effectively block heat transfer.

[0043] It should be noted that the heat insulation board 403 is provided with a first threading hole 4031 , the annular rib 410 is provided with a second threading hole 4101 , and the forked end 31 of the power cord 30 in the second chamber 402 passes through the first threading hole 4031 and the second threading hole 4101 to enter the first chamber 401 .

[0044] Embodiment 2:

[0045] like Figure 6As shown, in this embodiment, the junction box 40 further includes a receiving box 411 detachably connected to the inner wall of the second chamber 402, and a receiving chamber 406 is provided in the receiving box 411. With such a design, on the one hand, in later maintenance, only the damaged receiving box 411 needs to be replaced, and there is no need to replace the entire junction box 40, which is more cost-effective. On the other hand, there is no need to first install the forked end 31 of the power cord 30 into the receiving box 411 and then install the receiving box 411 in the junction box 40, which avoids installing the forked end 31 of the power cord 30 in a small space in the junction box 40, and makes assembly more convenient.

[0046] In order to facilitate the assembly of the receiving box 411, a positioning structure that matches the receiving box 411 is provided in the second chamber 402. Such a design makes the installation position of the receiving box 411 more accurate, thereby making the routing of the forked end 31 of the power cord 30 more reasonable.

[0047] Specifically, the positioning structure includes a protruding positioning rib 415 on the inner wall of the second chamber 402, and the positioning rib 415 and the inner wall of the second chamber 402 enclose a mounting cavity 416 that matches the receiving box 411. During assembly, the receiving box 411 is placed in the mounting cavity 416 and fixed by a pressure plate and screws.

[0048] It is understandable that in other embodiments of the present invention, the positioning structure may also include providing a positioning groove on the inner wall of the second chamber that matches the receiving box or providing a mark on the inner wall of the second chamber.

[0049] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
