Description

Technical Field

[0001] The invention relates to the field of electrical appliances, and in particular to an oven. Background Art

[0002] An oven is a sealed appliance used to bake food or dry products. The oven usually includes an outer shell and an inner shell. The inner shell is provided with working parts such as a heating tube for heating objects and a shelf for placing food in layers. In existing ovens, most of the working parts in the inner shell are fixed, which limits the functions of the oven. For example, when cleaning the oil stains on the inner wall of the inner shell after using the oven, it is difficult to clean the inner shell thoroughly because the heating tube is attached to the inner shell and there is a groove between the inner shell and the heating tube. Summary of the invention

[0003] The object of the present invention is to provide an oven to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] An oven, comprising an inner container, wherein a working piece is arranged in the inner container, and a moving device, wherein the moving device comprises:

[0006] A guide seat, which is fixedly connected to the inner container and is provided with a sliding hole communicating with the inner container;

[0007] A sliding piece is slidably connected to the sliding hole, extends toward the inner container and is connected to the working piece.

[0008] The beneficial effect of the present invention is that the working piece is connected with the sliding piece in the moving device, so that the position of the working piece in the inner pot can be adjusted by changing the position of the sliding piece, thereby expanding the function of the oven.

[0009] As a further improvement of the above technical solution, the moving device also includes a damping component, and the damping component is configured to increase the sliding resistance between the sliding member and the guide seat. The damping component is configured to increase the resistance between the sliding member and the guide seat, and by adjusting the damping component, the resistance between the sliding member and the guide seat is increased until the sliding resistance is slightly greater than the sliding force caused by the weight of the sliding member and the working member, so that the sliding member can rely on friction to remain relatively still with the guide seat at any position of the sliding stroke, and can rely on manual driving of the sliding member to slide along the sliding hole, so that the sliding member can be prevented from accidentally falling during the movement process of adjusting the position of the working member. On the other hand, the working member and the inner tank have multiple positions that can be kept relatively fixed, and the configuration of the working member is more flexible.

[0010] As a further improvement of the above technical solution, a concave platform is provided on the side of the sliding hole, and the concave platform is connected to the sliding hole. The damping assembly includes a damping member and a spring. The damping member is located at the concave platform. The damping member includes an abutment portion extending toward the sliding hole. The spring is arranged between the damping member and the guide seat and drives the abutment portion to abut against the sliding member. The damping member is kept in abutment with the sliding member through the spring, so that the sliding resistance of the damping member to the sliding member can be adjusted by changing the contact area between the damping member and the sliding member, or by changing the elastic force of the spring. The damping assembly has a simple structure and convenient resistance adjustment.

[0011] As a further improvement of the above technical solution, a positioning column / positioning hole is provided on the side wall of the concave platform away from the spring, and a positioning hole / positioning column plugged into the positioning column / positioning hole is also provided on the damping member. In the process of the sliding member sliding along the sliding hole, the damping member is subjected to friction along the axis of the sliding hole, and the damping member has a tendency to flip over. After the damping member flips over, the spring will be out of the damping assembly and will not work normally. In order to avoid this problem, the movement of the damping member is limited by providing a positioning column and a positioning hole to prevent the damping member from flipping over.

[0012] As a further improvement of the above technical solution, a groove is provided on the side wall of the sliding member, and the abutting portion extends into the groove and abuts against the bottom surface of the groove. The bottom surface of the groove refers to the surface pointing away from the opening direction of the groove. The abutting portion extends into the groove and abuts against the bottom surface of the groove, and the abutting portion can limit the sliding stroke of the sliding member under the limiting effect of the groove.

[0013] As a further improvement of the above technical solution, the moving device further includes a fixing component, and the fixing component is configured to keep the sliding member fixed to the guide seat at a certain position. In this improved technical solution, different from the damping component, the fixing component plays a role in keeping the sliding member and the guide seat relatively fixed through a larger force, so that the sliding member and the guide seat are not easy to slide relative to each other by manual driving, and the working piece is relatively firmly kept at a certain height to prevent the working piece from falling during operation.

[0014] As a further improvement of the above technical solution, the fixing assembly includes a magnet arranged on the sliding member or relatively fixed to the guide seat, and the magnet is configured to be fixed to the guide seat by magnetic force when the sliding member slides to a certain height. The magnet is used to fix the workpiece by magnetic adsorption, which has the advantages of simple structure, easy manufacturing, and convenient switching of fixed and separated states.

[0015] As a further improvement of the above technical solution, the working piece is a heating pipe, and when the sliding piece and the guide seat are fixed by magnetic force, the heating pipe is located on the upper side of the inner pot, and the oven also includes a shell, which is fixedly connected to the outside of the inner pot, and the inner pot is provided with a through installation port, the guide seat is fixed in the installation port, and the magnet is fixed on the top of the sliding piece. The working piece is a heating pipe, and when the heating pipe is in a working state, the sliding piece is fixed by magnetic adsorption, so that the heating pipe is located at the upper position of the inner pot, so that the heating pipe can be firmly fixed when working. When the inner wall of the inner pot needs to be cleaned, the heating pipe is driven away from the upper wall of the inner pot by sliding down the sliding piece, exposing the upper wall of the inner pot, so as to facilitate the thorough cleaning of the inner wall of the inner pot and improve the sanitary conditions of the inner pot of the oven. Since the magnetism of the magnet will weaken when it is heated, fixing the magnet on the top of the sliding piece keeps the magnet away from the heat source, and minimizes the heat transferred from the heat source, i.e., the heating pipe, to the magnet, which is conducive to ensuring the magnetic force of the magnet and ensuring that the heating pipe is firmly fixed. In addition, a through installation opening is provided on the inner tank, which is conducive to maximizing the use of the distance between the inner tank and the outer shell, so that the sliding part has a larger sliding stroke, so that the heating tube deviates farther from the upper wall of the inner tank, which is more conducive to exposing the upper wall of the inner tank for cleaning.

[0016] As a further improvement of the technical solution, the sliding member is further provided with a fixed cover, which extends out of the sliding hole in the radial direction of the sliding hole. Therefore, when the sliding member slides along the sliding hole, the fixed cover can abut against the end surface of the sliding hole, and the fixed cover limits the sliding stroke of the sliding member, thereby preventing the sliding member from falling out of the guide seat.

[0017] A commonly used work piece in the inner pot may also be a shelf, which is usually placed on the corner brackets of the inner wall of the inner pot. The height of the shelf is difficult to adjust to suit the food, which places certain limitations on maximizing the use of the space in the inner pot.

[0018] To this end, the present invention also provides an improved solution, wherein the working piece is a shelf and is connected to a sliding member. By connecting the shelf with a moving device, the shelf can be adjusted to the height position of the inner pot, so that the shelf can better adapt to the height of the food. Of course, in order to ensure that the shelf has a good load-bearing capacity to carry heavier food, the moving device may also include a structure for bearing weight, such as using a driving device to drive the connecting sliding member to drive the sliding member to slide along the guide seat, and using the braking force of the driving device to bear the weight, or, a snap-on structure with multiple corresponding positions is provided on the guide seat and the sliding member, and the sliding member and the guide seat have multiple corresponding positions that can bear weight, and the side of the card convex and the card groove are used to abut against the weight.

If there are descriptions such as "first", "second", etc., they are only used to distinguish technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] Reference Figure 1 to Figure 5 The embodiment is as follows: an oven includes an inner tank 100 and an outer shell 400, the upper wall of the inner tank 100 is provided with a through installation opening, the inner tank 100 is provided with a working piece 110, and the working piece 110 is a heating tube. The oven also includes:

[0031] The moving device includes a guide seat 210, which is fixed in the installation opening and is provided with a sliding hole 211 connected to the inner container 100;

[0032] The sliding member 220 is slidably connected to the sliding hole 211 and extends downward toward the inner container 100 . The working member 110 is fixed to the bottom of the sliding member 220 by screws.

[0033] The sliding member 220 and the guide seat 210 can be made of plastic, which has the advantages of low thermal conductivity, light weight and low cost. Of course, in order to prevent the guide seat 210 from softening due to the excessive temperature of the heating pipe, the guide seat 210 can be made of plastic with good temperature resistance, such as polytetrafluoroethylene.

[0034] The heating tube is connected to the sliding member 220 in the moving device, so that the position of the heating tube in the inner pot 100 can be adjusted by changing the position of the sliding member 220. When the upper wall of the inner pot 100 needs to be cleaned, the heating tube is moved so that the upper wall of the inner pot 100 is exposed, which can be easily cleaned and expand the function of the oven. Figure 4 When the heating tube is in a cleaning state, the heating tube leaves the upper wall of the inner tank 100, so that the upper wall of the inner tank 100 is exposed.

[0035] The sliding member 220 is hollow, and the power supply line of the heating tube is led out from the inside of the sliding member 220 through the wire hole 222 and electrically connected to the power supply board of the oven. In order to ensure that the heating tube can work normally, the length of the power supply line of the heating tube should be set so that when the heating tube is at the lower end of the sliding stroke of the sliding member 220, the power supply line is in a relaxed state, so as to avoid the problem that the power supply line interface is disconnected due to the tight pulling of the power supply line during the sliding process of the heating tube, resulting in failure of the heating tube.

[0036] The moving device further includes a damping component, which is used to increase the resistance between the sliding member 220 and the guide seat 210, in order to achieve such an effect: the sliding member 220 can slide along the guide seat 210 by manual drive, and when there is no external force driving the sliding member 220, the sliding member 220 can remain relatively fixed with the guide seat 210 by friction. Thus, when the position of the heating tube is adjusted, the heating tube can be kept fixed after being released, and it is not easy to touch the heating tube and cause it to fall when cleaning the upper wall of the inner tank 100.

[0037] Reference Figure 2The damping assembly includes a damping member 310 and a spring 320. The damping member 310 is installed at the concave platform 212 on the side wall of the sliding hole 211. The damping member 310 includes an abutting portion 311 close to one side of the sliding hole 211 and extending toward the sliding hole 211, and a plug column away from the sliding hole 211. The spring 320 is sleeved outside the plug column and abuts against the bottom surface of the concave platform 212, driving the abutting portion 311 to abut against the bottom mold of the groove 221 on the side of the sliding member 220. When the resistance of the damping assembly needs to be adjusted, the spring 320 with different elastic force can be replaced, or the damping member 310 with a different size or material of the abutting portion 311 can be replaced to change the resistance between the damping member 310 and the sliding member 220. When the groove 221 on the side of the sliding member 220 is closed along its length direction, the damping member 310 cooperates with the groove 221 to limit the sliding stroke of the sliding member 220.

[0038] Furthermore, since the damping member 310 is subjected to frictional force along the axis of the sliding hole during the sliding of the sliding member 220 along the sliding hole 211, the damping member 310 may flip over and cause the spring 320 to fall out, resulting in abnormal operation of the damping assembly. To this end, a plug-in column structure is provided to connect the damping member 310 to overcome the above problem of possible flipping. The plug-in column structure includes a positioning column 213 and a positioning hole 312. The shapes of the positioning column 213 and the positioning hole 312 correspond to each other. When the shape of the positioning column 213 is circular, two groups of the plug-in column structure need to be provided to prevent the damping member from rotating around the axis of the positioning column 213. When the shape of the positioning column 213 is non-circular, one group of the plug-in column structure is sufficient. The positioning column 213 and the positioning hole 312 in the plug-in column structure, since the plug-in column structure is interchangeable, the positioning column 213 and the positioning hole 312 can be respectively and correspondingly provided on the damping member 310 and the concave platform 212, or respectively and correspondingly provided on the concave platform 212 and the damping member 310.

[0039] The moving device also includes a fixing component. Different from the damping component, the fixing component is used to keep the sliding member 220 and the guide seat 210 relatively fixed and to keep the two fixed by a large force, so that the sliding member 220 and the guide seat 210 are not easy to slide relative to each other by manual driving, and the working member 110 is relatively firmly kept at a certain height to prevent the working member 110 from falling when working. Specifically, when the heating pipe is in the heating working state, such as Figure 3, the fixing assembly enables the heating pipe to be securely fixed on the upper side of the inner tank 100. In this embodiment, a magnet 223 is fixed on the top of the sliding member 220, and the outer shell 400 is made of a metal material with soft magnetism, so that the sliding member 220 is fixed on the outer shell 400 by magnetic adsorption. Of course, in order to increase the magnetic force, the magnet 223 can also be installed on the inner wall of the outer shell 400. In addition, it is worth mentioning that the magnet 223 is fixed on the top of the sliding member 220, which is far away from the heating pipe, which is conducive to ensuring the magnetic force of the magnet 223.

[0040] A fixing cover 224 is disposed on the upper side of the sliding member 220 . The fixing cover 224 is screwed onto the sliding member 220 . The fixing cover 224 extends out of the sliding hole 211 along the radial direction of the sliding hole 211 .

[0041] In another embodiment, the commonly used working piece 110 in the inner pot 100 can also be a shelf. In order to ensure that the shelf has a good load-bearing capacity to carry heavier food, the moving device can also include a structure for bearing weight, such as the fixing assembly in this embodiment, or a driving device drives the connecting sliding member 220 to drive the sliding member 220 to slide along the guide seat 210, and the braking force of the driving device is used to bear the weight, or a buckle structure with multiple corresponding positions is set on the guide seat 210 and the sliding member 220, and the sliding member 220 and the guide seat 210 have multiple corresponding positions that can bear weight, and the side of the clamping protrusion and the clamping groove is used to abut against the weight.

[0042] In another embodiment, the guide seat 210 and the sliding member 220 may be implemented in the form of a telescopic rod, which includes a sleeve rod fixedly connected to the inner liner 100 and a movable rod slidably connected to the sleeve rod, the sleeve rod is equivalent to the guide seat 210, and includes a sliding hole in the sleeve rod, which is equivalent to the sliding hole 211, and the movable rod is equivalent to the sliding member 220, which is connected to the working member 110. The working member 110 may be a heating tube or a layer plate.

[0043] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
