Description

Technical Field

[0001] The utility model belongs to the technical field of cooking utensils, and in particular relates to a guide rail device for a cooking utensil and the cooking utensil. Background Art

[0002] Some cooking appliances on the market (such as ovens, pizza machines, etc.) are equipped with a storage device for placing food in the inner pot; support frames are set on both sides of the inner pot, and the storage device is detachably set in the inner pot through the support frames. However, most of the support frames and storage devices are made of metal. When installing or taking out the storage device, the friction between the edge of the storage device and the support frame will cause the coating on the storage device to fall off, thereby affecting the service life of the storage device and the user experience.

[0003] In order to increase the wear resistance of the edge of the storage container and prevent the coating of the storage container from being rubbed off, most of the current storage containers rely on plastic parts or plastic edging to wrap the edge of the storage container. However, due to the high temperature inside the inner pot, these plastic accessories can hardly withstand it. Utility Model Content

[0004] The utility model provides a guide rail device for a cooking utensil and the cooking utensil, aiming to solve the problem in the prior art that the edge of the placement utensil is scratched due to the friction between the support frame in the inner pot and the placement utensil.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] In a first aspect, the utility model provides a guide rail device for a cooking utensil, comprising:

[0007] The guide rail seat is provided with a slide groove; the inner side wall of the slide groove is provided with at least one row of positioning holes along the sliding direction; and,

[0008] The ball assembly comprises a ball rotatably arranged in the positioning hole and an elastic member used for allowing the ball to elastically and telescopically extend into the sliding groove.

[0009] A further solution: when the positioning holes are arranged in a row, a slideway is formed between the balls and the inner sidewalls of the opposite slideways;

[0010] When two opposite inner side walls of the slide groove are each provided with a row of the positioning holes, a slideway is formed between the two rows of balls.

[0011] As a further solution, one or two rows of positioning holes may be provided to form a slideway in the slide groove, which has a simple structure and can reduce manufacturing costs.

[0012] A further solution: the slide groove is a U-shaped groove, and the upper wall, lower wall and bottom wall of the slide groove are each provided with a row of the positioning holes.

[0013] Based on the above solution, the upper wall, the lower wall and the bottom wall of the slide groove are each provided with a row of positioning holes, which can improve the smoothness and stability of sliding in the slide groove and reduce vibration during the sliding process.

[0014] A further solution: a row of the positioning holes is located on the inner wall on any side of the slide groove, and is a plurality of positioning holes arranged along the sliding direction of the slide groove; the ball is rotatably arranged in each of the positioning holes.

[0015] Based on the above solution, the ball bearing is rotatably arranged in each positioning hole, thereby changing the sliding friction into rolling friction, which can not only reduce the friction resistance of sliding in the slide groove, but also make sliding in the slide groove smoother.

[0016] A further solution: a mounting groove for mounting the elastic member is provided inside the guide rail seat;

[0017] Each of the positioning holes corresponds to a group of the ball assemblies; in each group of the ball assemblies, the elastic member is located in the mounting groove, and one end of the elastic member is connected to the ball, and the other end is against the bottom wall of the mounting groove.

[0018] Based on the above scheme, since the ball is located in the positioning hole, the width of the slide groove is compressed; an elastic member is designed in this scheme, so that when sliding in the slide groove, the width of the slide groove is adjusted by the elastic member to ensure the sliding space of the slide groove.

[0019] A further solution is that a plurality of positioning posts corresponding to the elastic members are arranged on the bottom wall of the mounting groove, and an end of the elastic member away from the ball is arranged on the positioning post.

[0020] Based on the above solution, the positioning column plays a positioning role to avoid the elastic member from being dislocated when sliding in the sliding groove.

[0021] A further solution: the elastic member is a spring; one end of the spring abuts against the ball, and the other end is sleeved on the positioning column and abuts against the bottom wall of the mounting groove;

[0022] A further solution is that the front end of the slide groove is provided with a slide entrance which gradually decreases from the outside to the inside.

[0023] Based on the above solution, the sliding entrance can play a guiding role, making it easy to find the entrance of the sliding groove and slide into the sliding groove smoothly.

[0024] A further solution: the ball and the elastic member are both made of metal.

[0025] Based on the above solution, the metal material has the characteristic of high temperature resistance and can withstand the high temperature in the inner pot.

[0026] In a second aspect, the utility model provides a cooking utensil, comprising an inner pot, a storage utensil capable of entering and exiting the inner pot, and two guide rail devices for a cooking utensil as described in any one of the first aspects;

[0027] The two guide rail seats are respectively arranged on the left and right sides of the inner pot, and the openings of the slide grooves on the two guide rail seats face the middle of the inner pot;

[0028] When the storage device moves in and out of the inner pot, the left and right ends of the storage device slide against the ball bearings in the slide groove, and the ball bearings rotate in the positioning hole relative to the storage device.

[0029] The beneficial effects of the utility model are:

[0030] In the utility model, at least one row of positioning holes is provided on the inner side wall of the slide groove, and a ball is rotatably provided in each of the positioning holes. When the storage device slides in the slide groove, the ball can rotate freely in the positioning hole, and the ball converts the sliding friction between the storage device and the slide groove into rolling friction, which not only reduces the friction force, but also reduces the impact force of the storage device when entering the slide groove, avoiding the problem of scratches and bruises on both ends of the storage device.

[0031] In addition, the elastic member connected to the ball ensures space for the storage device to slide in the slide groove, so that the two ends of the storage device can slide more smoothly in the corresponding slide groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The ball assembly includes a ball 3 rotatably disposed in the positioning hole 11 and an elastic member 4 for allowing the ball 3 to elastically extend into the slide groove 2 .

[0045] Specifically, the positioning holes 11 on the inner wall of the slide groove 2 can be arranged in one row, two rows or three rows;

[0046] When the positioning holes 11 are arranged in a row, a slideway is formed between the ball bearings 3 and the inner sidewalls of the corresponding slide grooves 2. It should be noted that a row of the positioning holes 11 can be arranged on any inner sidewall of the slide groove 2, for example, a row of the positioning holes 11 is arranged on the upper wall of the slide groove 2, a row of the positioning holes 11 is arranged on the lower wall of the slide groove 2, or a row of the positioning holes 11 is arranged on the bottom wall of the slide groove 2.

[0047] When there are two rows of positioning holes 11, and two opposite inner side walls are each provided with a row of positioning holes 11, a slideway is formed between the two rows of balls 3. That is, there are two rows of positioning holes 11, which are respectively provided on the upper wall and the lower wall of the slideway 2.

[0048] When there are three rows of positioning holes 11, the slide slot 2 is a U-shaped slot, and the upper wall, lower wall and bottom wall of the slide slot 2 are each provided with a row of positioning holes 11. It should be noted that the slide slot 2 is integrally arranged with the guide rail seat 1; the slide slot 2 is a U-shaped slot formed by a concave side wall of the guide rail seat 1.

[0049] A more specific example of the above scheme is: a row of the positioning holes 11 is located on the inner wall on any side of the slide groove 2, and a plurality of positioning holes 11 are arranged along the sliding direction of the slide groove 2; and the ball 3 is rotatably arranged in each of the positioning holes 11.

[0050] The number of the positioning holes 11 in a row of the positioning holes 11 can be set according to the length of the sliding direction of the slide groove 2. For example, the number of the positioning holes 11 in a row of the positioning holes 11 can be 8, 9, 10 or 11, etc. In this embodiment, the number of the positioning holes 11 in a row of the positioning holes 11 is 10.

[0051] like Figure 2 and Figure 3 As shown, a further example of the guide rail seat 1 is: a mounting groove 12 for mounting the elastic member 4 is provided inside the guide rail seat 1; it should be noted that: the slide groove 2 is a U-shaped groove formed by a concave side wall of the guide rail seat 1, and the space between the guide rail seat 1 and the slide groove 2 is hollow, namely the mounting groove 12.

[0052] Each of the positioning holes 11 corresponds to a group of the ball assemblies; in each group of the ball assemblies, the elastic member 4 is located in the mounting groove 12, and one end of the elastic member 4 is connected to the ball 3, and the other end rests on the bottom wall of the mounting groove 12.

[0053] A plurality of positioning posts 13 corresponding to the elastic members 4 are disposed on the bottom wall of the mounting groove 12 , and one end of the elastic member 4 away from the ball 3 is disposed on the positioning post 13 .

[0054] As a preferred solution, the elastic member 4 may be a spring; one end of the spring abuts against the ball 3, and the other end is sleeved on the positioning column 13 and abuts against the bottom wall of the mounting groove 12;

[0055] The positioning hole 11 is a circular hole, and the diameter of the positioning hole 11 is smaller than the diameter of the spring, so as to ensure that the spring does not pop out of the positioning hole 11. The positioning column 13 can be a circular column, and the diameter of the positioning column 13 is smaller than the diameter of the spring, so as to ensure that the end of the spring away from the ball 3 is sleeved on the positioning column 13 to play a positioning role.

[0056] like Figure 1 As shown, based on any of the above solutions, the front end of the chute 2 is provided with a sliding entrance 21 which gradually decreases from the outside to the inside. The front end of the chute 2 is located at an end close to the opening of the inner pot 5.

[0057] Specifically, the front end of the upper wall, the front end of the lower wall and the front end of the bottom wall of the slide groove 2 are all provided with slope surfaces, and together form the slide entrance 21. The shape of the slide entrance 21 can be similar to a trumpet shape.

[0058] In addition to the solution that the sliding entrance 21 is arranged at the front end of the sliding slot 2 , the sliding entrance 21 can also be arranged at the front end and the rear end of the sliding slot 2 at the same time.

[0059] On the basis of the above solution, the ball 3 and the elastic member 4 are both made of metal material. Alternatively, the ball 3 and the elastic member 4 are both made of high temperature resistant material.

[0060] Embodiment 2:

[0061] like Figure 4 and Figure 5 As shown, this embodiment provides a cooking utensil, comprising an inner pot 5, a storage container 6 that can be put in and out of the inner pot 5, and two guide rail devices for cooking utensil as described in the first embodiment;

[0062] The two guide rail seats 1 are respectively arranged on the left and right sides of the inner pot 5, and the openings of the slide grooves 2 on the two guide rail seats 1 face the middle of the inner pot 5;

[0063] When the storage device 6 enters and exits the inner pot 5 , the left and right ends of the storage device 6 slide against the ball bearings 3 in the slide groove 2 , and the ball bearings 3 rotate in the positioning hole 11 relative to the storage device 6 .

[0064] The first solution of the guide rail seat 1 being arranged on the inner pot 5 is: Figure 4As shown, the two guide rail seats 1 are integrally arranged on the left and right sides of the inner pot 5, and the openings of the slide slots 2 on the two guide rail seats 1 are both oriented toward the middle of the inner pot 5. The bottom wall of the mounting slot 12 is the side wall of the inner pot 5, that is, when the bottom wall of the slide slot 2 is also provided with a row of positioning holes 11, the end of the spring corresponding to the positioning holes 11 away from the ball 3 abuts against the side wall of the inner pot 5.

[0065] The second solution of the guide rail seat 1 being arranged on the inner pot 5 is as follows: Figure 5 As shown, the two guide rail seats 1 are respectively embedded on both sides of the inner pot 5, the slide grooves 2 of the two guide rail seats 1 are located in the inner pot 5, and the opening of each slide groove 2 faces the middle of the inner pot 5. The bottom wall of the mounting groove 12 is located outside the inner pot 5.

[0066] The two side walls of the inner pot 5 are provided with strip-shaped clearance holes 51 having a length equal to the length of the slide groove 2 along the sliding direction. When the bottom wall of the slide groove 2 is also provided with a row of positioning holes 11, the end of the spring corresponding to the positioning hole 11 close to the ball 3 passes through the strip-shaped clearance hole 51 and then abuts against the ball 3, and the end of the spring corresponding to the positioning hole 11 away from the ball 3 abuts against the bottom wall of the mounting groove 12.

[0067] In addition, the cooking utensil may be an oven, a pizza maker, etc. The storage utensil 6 may be a baking tray, a frying pan, a grill, a steaming rack, etc., which can be used to place food.

[0068] The present invention is further described below in conjunction with the working principle of the storage device 6 sliding into and out of the inner pot 5:

[0069] When the storage device 6 slides into the inner pot 5, the two ends of the storage device 6 are respectively inserted into the corresponding sliding entrances 21 of the sliding groove 2, pushing the storage device 6 inward. When the two ends of the storage device 6 contact the balls 3, under the action of the rotation of the balls 3, the storage device 6 will slide along the sliding groove 2. At the same time, the two ends of the storage device 6 press the balls 3 so that the spring will be compressed, ensuring that the two ends of the storage device 6 have space to slide in the sliding groove 2, thereby installing the storage device 6 in the inner pot 5.

[0070] When the storage device 6 slides out of the inner pot 5, the storage device 6 is pulled outward, and the two ends of the storage device 6 slide along the slide groove 2 under the action of the rotation of the ball 3. At the same time, the two ends of the storage device 6 press the ball 3 so that the spring is compressed, ensuring that the two ends of the storage device 6 have space to slide in the slide groove 2, thereby taking out the storage device 6.

[0071] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present utility model. However, no matter what changes are made in their shapes or structures, all technical schemes that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
