Frequent bending of the power cord is easy to cause damage to the power cord. Utility Model Content

[0003] Based on this, it is necessary to provide a power cord storage structure for an induction cooker to address the above problems of the existing induction cooker.

[0004] The present application discloses a power cord storage structure for an induction cooker, comprising a housing, a heating device and a control device installed inside the housing, a cord reel, and a power cord; wherein:

[0005] The bottom of the housing is provided with a first receiving groove;

[0006] The wire reel is arranged at the bottom of the housing, and the wire reel and the bottom of the housing are enclosed to form a second storage groove;

[0007] The power cord includes a wire and a power plug, one end of the wire is connected to the power plug, and the other end passes through the shell to be electrically connected to the control device. The wire can be stored in the second storage slot, and the power plug can be stored in the first storage slot.

[0008] The power cord storage structure of the induction cooker disclosed in the present application is characterized in that the cord reel cooperates with the bottom of the shell to form a second storage groove for storing the wires in the power cord, and the bottom of the shell is formed with a first storage groove for storing the power plug in the power cord. The power cord can be stored as a whole at the bottom of the shell and fixed, so as to avoid the power cord falling and causing safety risks, such as the transporter accidentally stepping on the fallen power cord and falling, causing damage to the transporter and the induction cooker, etc.; when the induction cooker is not in use, the power cord is stored at the bottom of the shell, so that the power cord storage remains beautiful and the storage space of the induction cooker is saved, and by winding the power cord along the path of the second storage groove, the frequent switching of the power cord between the unfolding and storage states can be effectively reduced, and the power cord is damaged due to frequent bending of different curvatures; in addition, by leading the power cord at the bottom of the shell, when the power cord is stored, the overall appearance of the induction cooker is not obviously prominent, which further saves the storage space of the induction cooker.

[0009] In one embodiment, the second receiving groove is annular.

[0010] The power cord storage structure of the induction cooker in the above embodiment further defines that the second storage groove formed by the winding seat and the bottom of the outer shell is formed into a ring shape. When the wire is wound and stored in the second storage groove, the wire bends along the path of the second storage groove and does not bend at a large angle, thereby reducing fatigue fracture of the metal in the wire and the protective layer sheathed on the metal periphery, thereby improving the durability of the wire.

[0011] In one embodiment, the width of the second receiving groove is greater than the diameter of the wire, and the wire is wound around the second receiving groove a plurality of times at the same level.

[0012] The power cord storage structure of the induction cooker in the above embodiment further limits the width of the second storage groove to be greater than the diameter of the wire, so that the second storage groove can only accommodate one wire at the same depth, and the wire can only be wound multiple times at the same horizontal height along the second storage groove, avoiding the problem of cross-knotting of the wire during the winding process.

[0013] In one of the embodiments, a fixing structure is disposed in the first receiving groove, and the fixing structure includes two limiting ribs, the two limiting ribs are distributed on both sides of the first receiving groove, and the interval between the two limiting ribs is greater than the diameter of the wire.

[0014] The power cord storage structure of the induction cooker in the above embodiment further defines a fixing structure in the first storage slot for fixing the conductive wire, wherein the fixing structure is composed of two limiting ribs arranged at intervals, wherein the interval between the two limiting ribs is greater than the diameter of the conductive wire, and the conductive wire is clamped between the two limiting ribs. The friction between the conductive wire and the limiting ribs is utilized to maintain the power plug stored in the first storage slot, and the friction between the conductive wire and the limiting ribs is utilized to maintain the power connector stored in the first storage slot, so that the power cord can be easily detached from the first storage slot and unfolded for use.

[0015] In one embodiment, there are multiple fixing structures, and the multiple fixing structures are distributed in the first receiving groove at intervals.

[0016] The power cord storage structure of the induction cooker in the above embodiment further defines that a plurality of fixing structures for fixing the wires are arranged in the first storage slot, so as to improve the stability of the power plug stored in the first storage slot and prevent it from falling off easily.

[0017] In one embodiment, the first receiving slot includes a wire segment, a transition segment and a plug segment connected in sequence, the wire segment is connected to the second receiving slot, and the projection of the plug segment on the shell is outside the projection range of the second receiving slot on the shell.

[0018] The power cord storage structure of the induction cooker in the above embodiment further defines that the first storage groove can be divided into three sections, namely a wire section, a transition section and a plug section, wherein the wire section is used to store the wires led out from the second storage groove, the transition section is used to store the connection between the wires and the power interface, and the plug section is used to store the power plug. The projection of the plug section on the outer casing is located outside the projection range of the second storage groove on the outer casing, so that the power plug will not be blocked by the cord reel during the storage process.

[0019] In one of the embodiments, the groove depth of the conductor segment and the groove depth of the transition segment gradually increase from the conductor segment to the transition segment.

[0020] The power cord storage structure of the induction cooker in the above embodiment further limits the groove depth of the wire segment and the groove depth of the transition segment to gradually increase from the wire segment to the transition segment, so as to ensure that the power cord can avoid large-angle bending at the connection between the power plug and the wire when the power cord is in the storage state.

[0021] In one of the embodiments, a plurality of supporting feet are formed at the bottom of the shell, and the plurality of supporting feet are spaced apart and distributed on the outer edge of the bottom of the shell, and the height of the supporting feet at the bottom of the shell is greater than the height of the winding seat at the bottom of the shell, and a gap is formed between two adjacent supporting feet, and the height of the gap is greater than the diameter of the wire.

[0022] The power cord storage structure of the induction cooker in the above embodiment is further defined as a plurality of supporting feet formed at the bottom of the shell, which can keep the bottom of the shell and the cord reel away from the ground; a gap with a height greater than the diameter of the wire is formed between two adjacent supporting feet, so that the wire can extend out of the bottom of the shell through the gap and connect to an external power supply when in the unfolded state.

[0023] In one of the embodiments, an air inlet is opened at the bottom of the shell, and the projection of the air inlet on the shell is located outside the projection range of the second receiving slot and the first receiving slot on the shell.

[0024] The power cord storage structure of the induction cooker in the above embodiment further defines an air inlet at the bottom of the shell, and the projection of the air inlet on the shell is located outside the projection range of the second storage slot and the first storage slot on the shell to reduce the influence of the cord reel and the power cord on the heat dissipation of the induction cooker.

[0025] In one embodiment, a wire outlet and a bending groove connected to the wire outlet are provided at the bottom of the shell, and the end of the wire away from the power connector passes through the wire outlet and the bending groove in sequence and is electrically connected to the control device. The wire is bent in the bending groove, and the wire outlet direction of the wire is along the path of the second receiving groove toward the wire inlet end of the first receiving groove.

[0026] The power cord storage structure of the induction cooker in the above embodiment further defines that a bending groove and a wire outlet are provided at the bottom of the shell for leading out the power cord, wherein the bending groove can bend a section of the wire from the control device to the wire outlet, so that the lead-out direction of the wire at the wire outlet is along the path of the second storage groove toward the wire inlet end of the first storage groove. When the winding direction of the wire is opposite, the wire needs to overcome the resistance of the bending of the wire when winding at the wire outlet, and a larger force needs to be applied. When the winding direction of the wire is correct, the wire can be wound around the second storage groove at the wire outlet along the bending direction of the wire at the bend, and the required force is smaller at this time; the lead-out direction of the wire at the wire outlet is along the path of the second storage groove toward the wire inlet end of the first storage groove, so that when the wire is led out in the second storage groove, the direction of the power connector matches the direction of the first storage groove; based on the cooperation of the above structure, during the power cord storage process, it is not easy to have the problem of wrong winding direction, resulting in repeated operations.

[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0038] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0039] like Figures 1 to 5 As shown, this embodiment provides a power cord storage structure for an induction cooker, comprising a housing 10, a heating device 40 and a control device 50 installed inside the housing 10;

[0040] The bottom of the housing 10 is provided with a first receiving slot 101;

[0041] The wire reel 20 is disposed at the bottom of the housing 10, and the wire reel 20 and the bottom of the housing 10 are enclosed to form a second receiving groove 201;

[0042] The power cord 30 includes a wire 31 and a power plug 32. One end of the wire 31 is connected to the power plug 32, and the other end passes through the housing 10 to be electrically connected to the control device 50. The wire 31 can be stored in the second storage slot 201, and the power plug 32 can be stored in the first storage slot 101.

[0043] The power cord storage structure of the induction cooker disclosed in the present application is that the winding seat 20 cooperates with the bottom of the shell 10 to form a second storage groove 201 for storing the wire 31 in the power cord 30, and the bottom of the shell 10 is formed with a first storage groove 101 for storing the power plug 32 in the power cord 30. The power cord 30 can be stored as a whole at the bottom of the shell 10 and fixed to avoid the power cord 30 falling and causing safety risks. For example, if the transporter accidentally steps on the fallen power cord 30 and falls, it will cause damage to the transporter and the induction cooker. When the induction cooker is not in use, the power cord 30 can be stored in the bottom of the shell 10 and fixed to avoid safety risks caused by the falling power cord 30. The power cord 30 is stored at the bottom of the outer shell 10, so that the power cord 30 is stored beautifully and saves storage space of the induction cooker. By winding the power cord 30 along the path of the second storage groove 201, the frequent switching of the power cord 30 between the unfolded and stored states can be effectively reduced. The power cord 30 is frequently bent with different curvatures, which may cause damage to the power cord. In addition, by leading the power cord 30 out at the bottom of the outer shell 10, the overall appearance of the induction cooker is not obviously prominent when the power cord 30 is in the stored state, which further saves the storage space of the induction cooker.

[0044] like Figures 2 to 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the second receiving groove 201 is annular.

[0045] The power cord storage structure of the induction cooker further defines that the second storage groove 201 formed by the winding seat 20 and the bottom of the housing 10 is formed into a ring shape. When the wire 31 is wound and stored in the second storage groove 201, the wire 31 bends along the path of the second storage groove 201 without a large angle bend, which reduces fatigue fracture of the metal in the wire 31 and the protective layer sleeved on the metal periphery, and improves the durability of the wire 31. It should be noted that in other embodiments, the cross section of the second storage groove 201 can be a polygon, such as a triangle, a quadrilateral, etc.

[0046] like Figure 5 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the width of the second receiving groove 201 is greater than the diameter of the wire 31, and the number of turns of the wire 31 around the second receiving groove 201 at the same horizontal height is multiple.

[0047] The power cord storage structure of the induction cooker further defines that the width of the second storage slot 201 is greater than the diameter of the wire 31, so that the wire 31 can only accommodate one wire 31 at the same depth of the second storage slot 201, and the wire 31 can only be wound multiple times at the same horizontal height along the second storage slot 201, thereby avoiding the problem of cross-knotting of the wire 31 during the winding process. Optionally, the wire 31 wound around the second storage slot 201 at the same horizontal height is N wires, the diameter of a single wire 31 is D, and the depth of the second storage slot 201 is greater than or equal to N*D, so that the wire 31 is not easy to fall off from the second storage slot 201 in the storage state.

[0048] like Figure 2 and Figure 4 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: a fixed structure is arranged in the first receiving groove 101, and the fixed structure includes two limiting ribs 110, and the two limiting ribs 110 are distributed on both sides of the first receiving groove 101, and the interval between the two limiting ribs 110 is greater than the diameter of the wire.

[0049] The power cord storage structure of the induction cooker described above further defines a fixing structure for fixing the wire 31 in the first storage slot 101, the fixing structure is composed of two spaced limiting ribs 110, the space between the two limiting ribs 110 is greater than the diameter of the wire 31, the wire 31 is sandwiched between the two limiting ribs 110, the friction between the wire 31 and the limiting rib 110 is used to keep the power plug 32 stored in the first storage slot 101, and the friction between the wire 31 and the limiting rib 110 is used to keep the power connector stored in the first storage slot 101, so that the power cord 30 can be easily detached from the first storage slot 101 and deployed for use. It should be noted that in other embodiments, the fixing structure can be a snap-fitting member, which can be snapped with the bottom of the housing 10, so that the source plug is kept stored in the first storage slot 101.

[0050] In addition to the features of the above embodiments, this embodiment further defines that: there are multiple fixing structures, and the multiple fixing structures are distributed in the first receiving groove 101 at intervals.

[0051] The power cord storage structure of the induction cooker further defines that a plurality of fixing structures for fixing the wire 31 are provided in the first storage slot 101 to improve the stability of the power plug 32 stored in the first storage slot 101 and prevent it from falling off by itself.

[0052] like Figure 3As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the first receiving slot 101 includes a wire segment 1011, a transition segment 1012 and a plug segment 1013 connected in sequence, the wire segment 1011 is connected to the second receiving slot 201, and the projection of the plug segment 1013 on the outer shell 10 is outside the projection range of the second receiving slot 201 on the outer shell 10.

[0053] The power cord storage structure of the above-mentioned induction cooker further defines that the first storage slot 101 can be divided into three sections, namely the wire segment 1011, the transition segment 1012 and the plug segment 1013, wherein the wire segment 1011 is used to store the wire 31 led out from the second storage slot 201, the transition segment 1012 is used to store the connection between the wire 31 and the power interface, and the plug segment 1013 is used to store the power plug 32. The projection of the plug segment 1013 on the outer shell 10 is located outside the projection range of the second storage slot 201 on the outer shell 10, so that the power plug 32 will not be blocked by the cord reel 20 during the storage process.

[0054] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the groove depth of the conductor segment 1011 and the groove depth of the transition segment 1012 gradually increase from the conductor segment 1011 to the transition segment 1012 .

[0055] The power cord storage structure of the above-mentioned induction cooker further limits the groove depth of the wire segment 1011 and the groove depth of the transition segment 1012 to gradually increase from the wire segment 1011 to the transition segment 1012, so as to ensure that the power cord 30 can avoid a large angle bend at the connection between the power plug 32 and the wire 31 when the power cord 30 is in the storage state.

[0056] like Figure 1 and Figure 2 As shown, in addition to the features of the above-mentioned embodiments, this embodiment is further defined as follows: a plurality of supporting feet 120 are formed at the bottom of the housing 10, the plurality of supporting feet 120 are spaced apart and distributed at the outer edge of the bottom of the housing 10, the height of the supporting feet 120 at the bottom of the housing 10 is greater than the height of the winding seat 20 at the bottom of the housing 10, and a notch 102 is formed between two adjacent supporting feet, and the height of the notch 102 is greater than the diameter of the wire 31.

[0057] The power cord storage structure of the above-mentioned induction cooker is further limited to that a plurality of supporting feet 120 are formed at the bottom of the outer shell 10, and the supporting feet 120 can keep the bottom of the outer shell 10 and the cord reel 20 away from the ground; a gap 102 with a height greater than the diameter of the wire 31 is formed between two adjacent supporting feet 120, so that the wire 31 can extend out of the bottom of the outer shell 10 through the gap 102 in the unfolded state and connect to an external power supply.

[0058] like Figure 2and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: an air inlet 103 is opened at the bottom of the shell 10, and the projection of the air inlet 103 on the shell 10 is located outside the projection range of the second storage slot 201 and the first storage slot 101 on the shell 10.

[0059] The power cord storage structure of the induction cooker further defines that an air inlet 103 is provided at the bottom of the housing 10, and the projection of the air inlet 103 on the housing 10 is located outside the projection range of the second storage slot 201 and the first storage slot 101 on the housing 10, so as to reduce the influence of the winding seat 20 and the power cord 30 on the heat dissipation of the induction cooker. It should be noted that a cooling fan 60 is provided in the housing 10, and the cooling fan 60 is arranged opposite to the air inlet 103.

[0060] like Figure 3 and Figure 4 As shown, in addition to the features of the above-mentioned embodiments, the present embodiment is further defined as follows: a wire outlet 104 and a bending groove 105 connected to the wire outlet 104 are provided at the bottom of the housing 10, and the end of the wire 31 away from the power connector passes through the wire outlet 104 and the bending groove 105 in sequence and is electrically connected to the control device 50, the wire 31 is bent in the bending groove 105, and the wire 31 is directed in the outlet direction of the wire outlet 104 along the path of the second receiving groove 201 toward the inlet end of the first receiving groove 101.

[0061] The power cord storage structure of the induction cooker further defines that a bending groove 105 and a wire outlet 104 for leading out the power cord 30 are provided at the bottom of the housing 10, wherein the bending groove 105 can bend a section of the wire 31 from the control device 50 to the wire outlet 104, so that the lead-out direction of the wire 31 at the wire outlet 104 is along the path of the second storage groove 201 toward the wire inlet end of the first storage groove 101. When the wire 31 is wound in the opposite direction, the wire 31 needs to overcome the resistance of the wire 31 to bend when it is wound at the wire outlet 104, and a large force needs to be applied. When the winding direction of 31 is correct, the wire 31 can be wound around the second receiving groove 201 at the wire outlet 104 along the bending direction of the wire 31 at the bend, and the required force is relatively small at this time; the lead-out direction of the wire 31 at the wire outlet 104 is along the path of the second receiving groove 201 toward the incoming end of the first receiving groove 101, so that when the wire 31 is led out of the second receiving groove 201, the direction of the power connector matches the direction of the first receiving groove 101; based on the cooperation of the above structure, during the storage process of the power cord 30, it is not easy to cause the problem of repeated operation due to the wrong winding direction.

[0062] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present utility model patent shall be subject to the attached claims.
