In the related art cooking appliance, as shown in fig. 1, one end of a power cord 400a extends out from a lower portion of a terminal box 200a, and the other end of the power cord 400a extends straight toward the inside of a housing 100 a. The power cord 400a inserted into the junction box 200a has a branch point, and the power cord 400a branches off a live wire, a neutral wire and a ground wire at the branch point, and these three wires are respectively connected to the internal components of the casing 100a and grounded to supply power to the internal components of the casing 100 a. The power line 400a is likely to be heated too high at the line branching point, and if the distance from the metal structure inside the casing 100a is too close, the temperature is likely to be excessively raised under the influence of the high temperature inside the casing 100a, which may cause a safety hazard. However, the length of the power cord 400a extending into the terminal box 200a is shorter, the power cord 400a extends straight in the terminal box 200a, and a branch point of the cord is sent into the inside of the casing 100a close to a metal structure, such as a cavity wall of a cooking cavity, which causes a safety hazard.

Moreover, in order to save cost, the current power cord 400a is a split structure, which includes two major portions, a built-in cord and an access cord. The built-in wire has a function of insulating heat radiation, such as a wire wrapped with a high temperature resistant fiber, and extends into the inside of the cabinet 100 a. The high temperature resistant effect of incoming line is relatively poor, low cost, for example by the line of PVC polyvinyl chloride parcel, incoming line and plug connection, incoming line and built-in line are connected together in terminal box 200 a. Therefore, when power cord 400a extends straight inside terminal box 200a, if the length of terminal box 200a is not increased, the distance between the inlet and housing 100a is too short, and the low-temperature working environment of the inlet is easily damaged, which may cause a safety hazard.

Therefore, under the condition that terminal box 200 length is less, cooking utensil occupation space is less, for the safety in utilization of improving power cord 400 in terminal box 200, the embodiment of the utility model provides a cooking utensil, power cord 400 stretches into terminal box 200 from the side direction of terminal box 200, and not straight insertion terminal box 200 to casing 100 has prolonged the line length of power cord 400 in terminal box 200, improves the safety in utilization of power cord 400.

Note that, in the present embodiment, the side wall of the junction box 200 refers to a wall circumferentially distributed in the horizontal direction when the product is placed upright. The terminal block 200 may be a split type, for example, assembled by the wire connection upper case 270 and the wire connection lower case 280, in which case the first, second, and third sidewalls 210, 220, and 230 of the terminal block 200 are constructed by walls after the wire connection upper case 270 and the wire connection lower case 280 are assembled together. Specifically, the wiring upper case 270 and the wiring lower case 280 may each have a portion of the first sidewall 210, each have a portion of the second sidewall 220, and each have a portion of the third sidewall 230; it is also possible to make the wiring upper case 270 flat, and to make only the sidewalls of the wiring lower case 280 configured as the first sidewall 210, the second sidewall 220, and the third sidewall 230, etc., depending on the shapes of the wiring upper case 270 and the wiring lower case 280, which are not listed herein. Fig. 2 to 10 illustrate a case where the wiring upper case 270 and the wiring lower case 280 each have a portion of the first sidewall 210, each have a portion of the second sidewall 220, and each have a portion of the third sidewall 230, and the first sidewall 210, the second sidewall 220, and the third sidewall 230 labeled in the wiring upper case 270 and the wiring lower case 280 respectively represent a portion of the first sidewall 210, a portion of the second sidewall 220, and a portion of the third sidewall 230 of the entire terminal block 200 in this order. The cooking appliance provided in the present embodiment will be described with reference to fig. 2 to 10.

Fig. 2 is a schematic view illustrating an overall structure of a cooking appliance according to an embodiment of the present invention, fig. 3 is a schematic view illustrating a cooking appliance when a wiring upper case 270 is detached from a wiring lower case 280, fig. 7 is a schematic view illustrating a structure when a portion of a first side wall 210, a portion of a second side wall 220, and a portion of a third side wall 230 are provided on the wiring upper case 270, and fig. 8 and 9 are schematic views illustrating a structure when the wiring lower case 280 has another portion of the first side wall 210, another portion of the second side wall 220, and another portion of the third side wall 230. As shown in fig. 2, 3, 7, 8 and 9, an embodiment of an aspect of the present invention provides a cooking appliance, including: a housing 100; the junction box 200 is arranged at the bottom of the side wall of the chassis 100, the junction box 200 has a first side wall 210 near the middle of the chassis 100, a second side wall 220 distributed opposite to the first side wall 210, and a third side wall 230 connecting the first side wall 210 and the second side wall 220, a first wire passing hole 231 is arranged on the part of the third side wall 230 exposed out of the chassis 100, and a second wire passing hole 232 is arranged on the part of the third side wall 230 extending into the interior of the chassis 100 or the first side wall 210; the wire pressing structure 300 is arranged in the junction box 200, and a limiting hole 310 is formed in the wire pressing structure 300; the first end of the power cord 400 is provided with a power plug, and the second end of the power cord 400 passes through the first wire passing hole 231 and the limiting hole 310 in sequence and then turns to extend into the second wire passing hole 232.

The cooking appliance provided by the embodiment of the present invention is provided with a junction box 200 at the bottom of the side wall of the casing 100, wherein the junction box 200 has a first side wall 210 close to the casing 100, a second side wall 220 far away from the casing 100, and a third side wall 230 connecting the first side wall 210 and the second side wall 220. By arranging the first wire passing hole 231 on the portion of the third side wall 230 exposed out of the casing 100 and the second wire passing hole 232 on the portion of the third side wall 230 extending into the casing 100 or on the first side wall 210, the second end of the power cord 400 can enter the inside of the junction box 200 through the first wire passing hole 231 from the side of the junction box 200, and then needs to be bent at least once to extend into the second wire passing hole 232, so that the wiring length of the power cord 400 inside the junction box 200 can be extended under the condition that the length of the junction box 200 is small and the occupied space of the cooking appliance is small. Therefore, under the condition that the length of the power line 400 is consistent from the position where the power line 400 extends into the junction box 200 to the line branching point of the power line 400, the power line 400 can extend straightly in the junction box 200, the line branching point of the power line 400 is beneficial to being away from the metal structure in the case 100 and cannot be straightly sent to the case 100, the phenomenon that the temperature rise of the line branching point of the power line 400 is too high under the influence of the high temperature inside the case 100 is avoided, and the use safety of the power line 400 is improved.

As an example, since the power cord 400 is extended into the junction box 200 from a lateral side of the junction box 200, a branching point of the power cord 400 may be laterally sent to a position close to the other third side wall 230 opposite to the first wire passing hole 231, far from the first side wall 210, ensuring that the branching point operates in a low temperature environment. Of course, the line branching point of the power line 400 may also be located at or near the bending region of the power line 400 and may also be far away from the first sidewall 210, so as to avoid an excessive temperature rise at the line crossing point.

In addition, set up line ball structure 300 in terminal box 200, be favorable to restricting the position of power cord 400 through line ball structure 300, and then restrict the position of line bifurcation point, can make the line bifurcation point of power cord 400 keep in the position far away from casing 100, improve the security.

In addition, in the case that the second wire through hole 232 is provided at a portion of the third sidewall 230 protruding into the inside of the set cover 100, referring to fig. 8 and 9, the power cord 400 may extend in a substantially wu 21274within the junction box 200, the power cord 400 extends inside the first sidewall 210 and then laterally protrudes from the third sidewall 230, and the first sidewall 210 may serve as a heat insulation for the power cord 400, further improving the safety of the use of the power cord 400.

In addition, the power cord 400 is bent and extends into the second wire passing hole 232 after passing through the wire passing hole of the wire pressing structure 300, so that when the power cord 400 comprises two large parts, namely the built-in power cord 400 and the access power cord 400, one part of the access power cord 400 is facilitated to be limited by the wire pressing structure 300 before bending and away from the first side wall 210, and therefore the access power cord 400 is facilitated to be kept in a working environment with lower temperature, and the use safety of the power cord 400 is improved.

In some embodiments, as shown in fig. 8 and 9, the axis of the limiting hole 310 extends in the same direction as the axis of the first wire passing hole 231.

In these embodiments, the wire pressing structure 300 is substantially flush with the third side wall 230, which is beneficial to make the second end of the power cord 400 extend into the junction box 200 from the side direction, continue to extend forward along the extending direction of the axis of the first wire passing hole 231, and then be limited by the wire pressing structure 300, so that the part of the power cord 400 before bending does not approach the first side wall 210, and the probability of heat fusion of the power cord 400 is reduced. In addition, in the case that the length of the power cord 400 routed from the position where the power cord extends into the junction box 200 to the branching point of the power cord 400 is consistent, the branching point of the power cord 400 may not be easily close to the first sidewall 210, for example, the branching point of the power cord may be close to another third sidewall 230 opposite to the first wire passing hole 231 or a bent region, thereby improving the safety of the power cord 400.

In some embodiments, as shown in fig. 8 and 9, a partition 240 is disposed in the junction box 200, the partition 240 encloses a first accommodating cavity 250 with the first side wall 210 and the third side wall 230, and the partition 240 encloses a second accommodating cavity 260 with the second side wall 220 and the third side wall 230; the first wire through hole 231 is located on the cavity side wall of the second accommodating cavity 260, the wire pressing structure 300 is arranged in the second accommodating cavity 260, and the partition plate 240 is provided with a third wire through hole 241 for the power line 400 to pass through.
