Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to an induction cooker.

Background Art

[0002] The induction cooker in the prior art includes a housing and a display board arranged inside the housing. A key spring is arranged on the display board, and the housing is provided with an operation part corresponding to the key spring. The operation part can be a touch key. One end of the key spring abuts against the operation part. When the part of the housing with the operation part is a curved surface, one end of the key spring will move on the curved surface, resulting in the inability to correspond to the operation part, thus leading to a poor key-pressing experience for users. To avoid the above situation, a guide sleeve is arranged on the back of the existing housing, and the guide sleeve is sleeved outside the key spring to prevent one end of the key spring from moving on the curved surface. However, in this way, not only will the appearance surface of the housing corresponding to the guide sleeve have a shrinkage problem, but also it will be impossible to inject and mold a screw post by core-pulling at a position adjacent to the guide sleeve to fix the display board, resulting in a thicker part of the housing appearance surface corresponding to the screw post and a shrinkage problem, thereby reducing the appearance of the housing.

Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an induction cooker. By making the guide sleeve independent of the housing, the shrinkage problem of the housing appearance surface is avoided, ensuring the appearance of the housing. At the same time, the guide sleeve can be fixed by relying on the installation of the light guide cover in an integrally formed manner, without setting additional structures on the housing to fix the guide sleeve, thus simplifying the housing structure.

[0004] To solve the above technical problem, the utility model adopts the following technical solutions:

[0005] An induction cooker includes a housing and a display board arranged inside the housing. The display board is provided with a key spring, an indicator light, and a light guide cover covering the outside of the indicator light. The wall of the housing is provided with a light-transmitting part corresponding to the light guide cover and an operation part corresponding to the key spring. A guide sleeve independent of the housing is sleeved outside the key spring, and the guide sleeve is integrally formed with the light guide cover.

[0006] In the above induction cooker, the light-transmitting part is a light-transmitting hole. The light guide cover includes an integrally formed cover body and a light guide column. The cover body covers the outside of the indicator light, and the light guide column penetrates through the light-transmitting hole.

[0007] In the above induction cooker, the wall of the housing includes an arc-shaped installation wall. The light-transmitting part and the operation part are both arranged on the installation wall. A limiting rib surrounding the light-transmitting part is arranged on the inner side surface of the installation wall. The light guide cover has a mating surface that forms a planar fit with the limiting rib.

[0008] In the above-mentioned induction cooker, a mating surface is provided on the end face of the light guide cover close to the mounting wall, and the end face of the limiting rib abuts against the mating surface to form a planar fit.

[0009] In the above-mentioned induction cooker, the limiting rib is arranged around the light guide cover, and a limiting plate extending outward is provided on the outer side of the light guide cover. The side of the limiting plate facing the limiting rib forms the mating surface, and the end face of the limiting rib abuts against the mating surface to form a planar fit.

[0010] In the above-mentioned induction cooker, the light-transmitting part is a light-transmitting hole penetrating the mounting wall. The light guide cover has a light guide column inserted into the light-transmitting hole, and the mating surface is perpendicular to the axis of the light-transmitting hole.

[0011] In the above-mentioned induction cooker, the light guide cover has an abutting surface facing the display board, and the abutting surface is parallel to and abuts against the side surface of the display board facing the light-transmitting part.

[0012] In the above-mentioned induction cooker, an installation sleeve extending inward and sleeving on the outer side of the light guide cover is provided on the wall of the housing. A buckle is provided on the outer side wall of the installation sleeve, and the light guide cover is provided with an elastic clamping arm clamped with the buckle.

[0013] In the above-mentioned induction cooker, a gap for accommodating the wall of the installation sleeve is provided between the guiding sleeve and the light guide cover, and an avoidance opening for avoiding the installation sleeve is provided on the side of the guiding sleeve facing the light guide cover.

[0014] In the above-mentioned induction cooker, the display board is provided with a plurality of indicator lights and a plurality of key springs. The indicator lights and the key springs are arranged in one-to-one correspondence, and adjacent two light guide covers and / or adjacent two guiding sleeves are connected by connecting ribs.

[0015] Advantages of the present utility model:

[0016] 1. In the present utility model, the guiding sleeve sleeved on the outer side of the key spring is independently arranged from the housing, and the guiding sleeve and the light guide cover sleeved on the outer side of the indicator light are integrally formed. Thus, it is avoided that the guiding sleeve is arranged on the housing, resulting in a shrinkage problem on the appearance surface of the housing, thereby ensuring the appearance of the housing. In addition, when the light guide cover is connected to the wall of the housing, the integrally formed manner can also fix the guiding sleeve by relying on the installation of the light guide cover, without the need to set additional structures on the housing to fix the guiding sleeve, thereby simplifying the housing structure. Finally, the integrally formed manner also omits the assembly process of the light guide cover and the guiding sleeve, thereby simplifying the assembly steps of the product.

[0017] 2. The light-transmitting part is a light-transmitting hole. The light guide cover includes an integrally formed cover body and a light guide column. The cover body covers the outside of the indicator light, and the light guide column penetrates through the light-transmitting hole. With such a design, the cover body can concentrate the light of the indicator light onto the light guide column to reduce the loss during the light propagation process, and then the light is converged to the light-emitting surface outside the light guide column through the light guide column to form a good lighting display effect. In addition, the cooperation between the light guide column and the light-transmitting hole can also further fix the light guide cover to improve the installation reliability of the light guide cover.

[0018] 3. The wall part of the housing includes an arc-shaped mounting wall. The light-transmitting part and the operating part are both arranged on the mounting wall. A limiting rib surrounding the light-transmitting part is arranged on the inner side surface of the mounting wall. The light guide cover has a mating surface that forms a planar fit with the limiting rib. To ensure the fit between the light guide cover and the mounting wall, when the mounting wall is arc-shaped, the part of the light guide cover that mates with the mounting wall also needs to be provided with a corresponding arc surface to ensure a good fit and correspondence between the light guide cover and the light-transmitting part, so as to ensure that the light guide cover guides the light through the light-transmitting part and improve the display effect. If there is a large difference between the arc surface of the light guide cover that mates with the mounting wall and the radian of the mounting wall, it will cause poor fit between the light guide cover and the housing, that is, it is skewed relative to the light-transmitting part, which not only affects the light guide effect, but also may cause a large gap between the light guide cover and the housing when the light-transmitting part is a light-transmitting hole, resulting in risks of water leakage and machine burnout. Therefore, this technical solution has high requirements for product processing accuracy. In this solution, by setting the limiting rib and making the limiting rib form a planar fit with the mating surface of the light guide cover, compared with the curved surface fit, the degree of freedom of movement of the light guide cover relative to the housing is lower, and the positioning is more accurate. Thus, it is easier for the light guide cover and the housing to form a good fit, avoiding problems such as poor display effect and large gaps between the light guide cover and the light-transmitting part, and further reducing the occurrence of water leakage problems.

[0019] 4. The end face of the light guide cover close to the mounting wall is provided with a mating surface. The end face of the limiting rib abuts against the mating surface and forms a planar fit. With such a design, the length of the limiting rib can be shortened to avoid the problem of shrinkage on the appearance surface of the housing.

[0020] 5. The limiting rib surrounds the light guide cover. A limiting plate extending outward is arranged on the outside of the light guide cover. The side of the limiting plate facing the limiting rib forms a mating surface. The end face of the limiting rib abuts against the mating surface and forms a planar fit. With such a design, the limiting rib can radially limit the light guide cover to prevent the light guide cover from moving in its radial direction, thereby further ensuring the accuracy of the installation position of the light guide cover.

[0021] 6. The light-transmitting part is a light-transmitting hole penetrating through the mounting wall. The light guide cover has a light guide column inserted into the light-transmitting hole, and the mating surface is perpendicular to the axis of the light-transmitting hole. During assembly, since the light guide column is inserted into the light-transmitting hole along the axis of the light-transmitting hole, making the mating surface perpendicular to the axis of the light-transmitting hole can ensure that after the light guide column is inserted into the light-transmitting hole in place, the mating surface and the limiting rib form a planar fit, eliminating the need to adjust the cover body, thus reducing the assembly difficulty between the light guide cover and the housing.

[0022] 5. The limiting ribs enclose a conical hole coaxially arranged with the light-transmitting hole, and the aperture of the conical hole gradually increases towards the display board. With this design, the light guide column can be smoothly inserted into the conical hole and smoothly inserted and mated with the light-transmitting hole under the guidance of the conical hole, thus reducing the assembly difficulty between the light guide column and the housing.

[0023] 6. The light guide cover has an abutting surface facing the display board, and the abutting surface is parallel and abuts against the side surface of the display board facing the light-transmitting part. With this design, the light guide cover can be clamped and fixed between the display board and the wall of the housing to prevent the light guide cover from moving between the wall of the housing and the display board, thus improving the installation reliability of the light guide cover.

[0024] 7. The wall of the housing is provided with a mounting sleeve extending inward and sleeving outside the light guide cover. The outer side wall of the mounting sleeve is provided with a buckle, and the light guide cover is provided with an elastic clamping arm clamped with the buckle. With this design, the light guide cover can be fixed on the housing by clamping. Compared with screw connection, it not only facilitates the quick installation of the light guide cover but also saves screws, thus reducing the production cost. In addition, the design of the mounting sleeve also meets the creepage distance requirements of the indicator light, thus meeting the safety regulations requirements.

[0025] 8. A gap for accommodating the wall of the mounting sleeve is provided between the guide sleeve and the light guide cover. An avoidance opening for avoiding the mounting sleeve is provided on the side of the guide sleeve facing the light guide cover. Since the indicator light is usually arranged adjacent to the key spring, setting an avoidance opening on the side of the guide sleeve facing the light guide cover can avoid interference between the guide sleeve and the mounting sleeve.

[0026] 9. The display board is provided with a plurality of indicator lights and a plurality of key springs. The indicator lights and the key springs are arranged in one-to-one correspondence. Adjacent two light guide covers and / or adjacent two guide sleeves are connected by connecting ribs. With this design, during assembly, the number of times of taking and placing parts can be reduced to improve the assembly efficiency. And when the connection of one light guide cover or guide sleeve fails, the fixed other light guide cover or guide sleeve can also fix the light guide cover or guide sleeve with the failed connection, preventing the light guide cover or guide sleeve with the failed connection from falling off.

[0027] These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and drawings.

Specific embodiments

[0040] The utility model provides an induction cooker, which comprises a housing and a display board arranged inside the housing. A key spring, an indicator lamp and a light guide cover covering the outside of the indicator lamp are arranged on the display board. A light-transmitting part corresponding to the light guide cover and an operation part corresponding to the key spring are arranged on the wall part of the housing. A guide sleeve independently arranged from the housing is sleeved outside the key spring, and the guide sleeve is integrally formed with the light guide cover.

[0041] In the utility model, the guide sleeve sleeved outside the key spring is independently arranged from the housing, and the guide sleeve is integrally formed with the light guide cover covering the outside of the indicator lamp. Thereby, the problem of shrinkage on the appearance surface of the housing caused by arranging the guide sleeve on the housing is avoided, and thus the appearance of the housing is ensured. In addition, when the light guide cover is connected to the wall part of the housing, the integrally formed manner can also fix the guide sleeve depending on the installation of the light guide cover, without arranging additional structures on the housing to fix the guide sleeve, thereby simplifying the housing structure. Finally, the integrally formed manner also omits the assembly process of the light guide cover and the guide sleeve, thereby simplifying the assembly steps of the product.

[0042] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them.

[0043] Embodiment 1

[0044] As Figures 1 to 9As shown in the figure, the induction cooker in this embodiment includes a housing 100, a display board 200, an electromagnetic coil disc 600, and a main control board 700 disposed within the housing 100. On the display board 200, there are key springs 210, indicator lights 220, and a light guide cover 300 disposed outside the indicator lights 220. The light guide cover 300 is independently disposed from the display board 200 and the housing 100. The wall of the housing 100 is provided with a light-transmitting portion 110 corresponding to the light guide cover 300 and an operating portion 120 corresponding to the key springs 210. An independently disposed guide sleeve 400 is sleeved outside the key springs 210. This avoids the problem of shrinkage on the appearance surface of the housing 100 caused by the guide sleeve 400 being disposed on the housing 100, thereby ensuring the appearance of the housing 100. In addition, the guide sleeve 400 and the light guide cover 300 are integrally formed. In this way, when the light guide cover 300 is connected to the wall of the housing 100, the guide sleeve 400 can be fixed by relying on the installation of the light guide cover 300, without the need to provide additional structures on the housing 100 to fix the guide sleeve 400, thus simplifying the structure of the housing 100. Finally, the integrally formed method also eliminates the assembly process of the light guide cover 300 and the guide sleeve 400, thereby simplifying the assembly steps of the product.

[0045] Specifically, the housing 100 in this embodiment includes a bottom cover 101 and an upper cover 102. The bottom cover 101 and the upper cover 102 are assembled by screw connection to form the housing 100. The side wall of the upper cover 102 forms part of the wall of the housing 100. In the use state, the light-transmitting portion 110 and the operating portion 120 are provided on the side of the side wall of the upper cover 102 facing the user. The light-transmitting portion 110 in this embodiment is a light-transmitting hole penetrating the wall of the housing. The light guide cover 300 includes an integrally formed cover body 310 and a light guide column 320. The cover body 310 is disposed outside the indicator light 220, and the light guide column 320 is disposed through the light-transmitting hole. With such a design, the cover body 310 can concentrate the light of the indicator light 220 onto the light guide column 320 to reduce the loss during the light propagation process, and then the light is converged to the light-emitting surface outside the light guide column 320 through the light guide column 320 to form a good lighting display effect. In addition, the cooperation between the light guide column 320 and the light-transmitting hole can also further fix the light guide cover 300 to improve the installation reliability of the light guide cover 300.

[0046] In this embodiment, the front side wall of the upper cover 102 is an arc-shaped mounting wall. The light-transmitting portion 110 and the operating portion 120 are both arranged on the mounting wall. A limiting rib 130 surrounding the light-transmitting hole is provided on the inner side surface of the mounting wall. The limiting rib 130 is an annular rib. The end surface of the cover body 310 connected to the light guide column 320 has a mating surface 311. The mating surface 311 is arranged around the light guide column 320. The mating surface 311 and the end surface of the limiting rib 130 facing away from the mounting wall form a planar fit. In order to ensure the fit degree between the cover body 310 and the mounting wall, when the mounting wall is arc-shaped, the part of the cover body 310 that mates with the mounting wall also needs to be provided with a corresponding arc surface to ensure the smooth fit between the light guide column 320 and the light-transmitting hole. If there is a large difference between the arc surface of the cover body 310 that mates with the mounting wall and the radian of the mounting wall, it will lead to poor fit between the light guide column 320 and the housing 100, not only affecting the light guide effect, but also possibly causing a large gap between the light guide column 320 and the light-transmitting hole, resulting in the risks of water leakage and machine burnout. Therefore, this technical solution has high requirements for the processing accuracy of the product. In this embodiment, by providing the limiting rib 130 and making the limiting rib 130 and the mating surface 311 of the cover body 310 form a planar fit, compared with the curved surface fit, the degree of freedom of movement of the cover body 310 relative to the housing 100 is lower, and the positioning is more accurate. Thus, it is easier to form a good fit between the cover body 310 and the housing 100, avoiding the problem of a large gap between the light guide column 320 and the light-transmitting hole, and further reducing the occurrence of water leakage problems.

[0047] It can be understood that in other embodiments of the present invention, the limiting ribs are dot-shaped ribs, and a plurality of limiting ribs are arranged at intervals circumferentially around the light-transmitting hole.

[0048] Preferably, the mating surface 311 in this embodiment is perpendicular to the axis of the light-transmitting hole. During assembly, since the light guide column 320 is inserted into the light-transmitting hole along the axis of the light-transmitting hole, making the mating surface 311 perpendicular to the axis of the light-transmitting hole can make the light guide column 320 inserted into place in the light-transmitting hole, that is, make the mating surface 311 and the end surface of the limiting rib 130 facing away from the mounting wall form a planar fit, without adjusting the cover body. Thus, the assembly difficulty between the light guide cover 300 and the housing 100 is reduced. Preferably, the axis of the light-transmitting hole is horizontally arranged. At this time, both the mating surface 311 and the end surface of the limiting rib 130 facing away from the mounting wall are vertically arranged planes.

[0049] It can be understood that in other embodiments of the present invention, when the axis of the light-transmitting hole is inclined, at this time, both the mating surface and the end surface of the limiting rib facing away from the mounting wall are inclined planes.

[0050] In addition, the limiting ribs 130 in this embodiment enclose a conical hole 140 coaxially arranged with the light-transmitting hole. The conical hole 140 communicates with the light-transmitting hole. The aperture of the conical hole 140 gradually increases in the direction of the display panel 200. The minimum aperture of the conical hole 140 is equal to the aperture of the light-transmitting hole. With such a design, the light guide column 320 can be smoothly inserted into the conical hole 140 and smoothly plugged and matched with the light-transmitting hole under the guidance of the conical hole 140, thereby reducing the assembly difficulty between the light guide column 320 and the housing 100.

[0051] As Figure 2 , Figure 3 and Figure 9 shown, screw posts are provided on the wall of the housing 100 in this embodiment. The display panel 200 is fixed to the screw posts by screws, that is, the display panel 200 is fixed to the installation wall by screws, and the light guide cover 300 is fixedly connected to the wall of the housing 100, that is, the light guide cover 300 is connected to the installation wall. In order to facilitate the quick assembly of the light guide cover 300 and the installation wall, an integrally formed and inwardly extending installation sleeve 150 is provided on the installation wall in this embodiment. The installation sleeve 150 is sleeved outside the light guide cover 300. A buckle 151 is provided on the outer side wall of the installation sleeve 150. An elastic clamping arm 330 is connected to the outer side of the cover body 310. The elastic clamping arm 330 includes a connecting section 331 and an elastic section 332. The elastic section 332 extends along the axial direction of the cover body 310 and is spaced from the cover body 310. The connecting section 331 connects one end of the elastic section 332 to the cover body 310. The other end of the elastic section 332 is provided with an inverted buckle structure. When the light guide cover 300 is assembled with the housing 100, when the inverted buckle structure contacts the buckle 151, the elastic section 332 can be deformed in the direction away from the cover body 310 to avoid the buckle 151. After the inverted buckle structure passes over the buckle 151, the elastic section 332 resumes to make the inverted buckle structure engage with the buckle 151, thereby completing the engagement between the elastic clamping arm 330 and the buckle 151. With such a design, the light guide cover 300 can be fixed to the housing 100 by a clamping method. Compared with screw connection, it not only facilitates the quick installation of the light guide cover 300, but also saves screws, thereby reducing the production cost. In addition, the design of the installation sleeve 150 also meets the creepage distance requirements of the indicator lamp 220, thereby meeting the safety regulations requirements.

[0052] As Figure 6As shown in the figure, in order to further enhance the installation reliability of the light guide cover 300, the light guide cover 300 in this embodiment has an abutting surface 340 facing the display board 200, and the abutting surface 340 is parallel to and abuts against the side surface of the display board 200 facing the light-transmitting part 110. With such a design, the light guide cover 300 can be clamped and fixed between the display board 200 and the wall of the housing 100, so as to prevent the light guide cover 300 from moving between the wall of the housing 100 and the display board 200. Even if the elastic clamping arm 330 fails to be clamped with the buckle 151, the light guide cover 300 can be prevented from moving, thereby improving the installation reliability of the light guide cover 300.

[0053] It can be understood that in other embodiments of the present invention, the wall of the housing is provided with elastic clamping arms extending inwardly, and a plurality of elastic clamping arms are circumferentially spaced around the light-transmitting hole. The end of the elastic clamping arm is provided with an inverted buckle structure, and the outer peripheral side of the cover body is provided with a buckle. The elastic clamping arm is clamped with the buckle through the inverted buckle structure. With such a design, the light guide cover can also be clamped on the wall of the housing.

[0054] Since the indicator lamp 220 is usually used to indicate the operation state of the operation part 120, the indicator lamp 220 will be arranged adjacent to the key spring 210. In this way, the distance between the light guide cover 300 and the guide sleeve 400 is also small. In addition, the installation wall is also provided with an installation sleeve 150 sleeved outside the light guide cover 300. Therefore, in order to avoid the installation sleeve 150, a gap for accommodating the wall of the installation sleeve 150 is provided between the guide sleeve 400 and the light guide cover 300 in this embodiment. The side of the guide sleeve 400 facing the light guide cover 300 is provided with an avoidance opening 410 for avoiding the installation sleeve 150. With such a design, the distance between the indicator lamp 220 and the key spring 210 can be further shortened, and at the same time, interference between the guide sleeve 400 and the installation sleeve 150 can be avoided.

[0055] Finally, in this embodiment, the display board 200 is provided with a plurality of indicator lamps 220 and a plurality of key springs 210, and the indicator lamps 220 and the key springs 210 are arranged in one-to-one correspondence. Adjacent two light guide covers 300 are connected by a connecting rib 500. With such a design, during assembly, the number of times of taking and placing parts can be reduced to improve the assembly efficiency; in addition, when the light guide cover 300 is clamped with the wall of the housing 100, if one of the light guide covers 300 fails to be clamped, the fixed light guide cover 300 can also be used to fix the light guide cover 300 whose connection has failed, avoiding the light guide cover 300 whose connection has failed from falling off.

[0056] It can be understood that in other embodiments of the present invention, the inner side surface of the wall of the housing forms a light-transmitting part by setting a groove to locally thin the wall of the housing, so as to enhance the light-transmitting effect of the light-transmitting part. At this time, the light guide column is inserted into the groove.

[0057] Embodiment 2

[0058] Compared with the first embodiment, the difference in this embodiment is that the limiting rib is an annular rib, and the inner diameter of the limiting rib is greater than the outer diameter of the cover body. The limiting rib surrounds the outside of the cover body 310. That is, the limiting rib in this embodiment is equivalent to the mounting sleeve in the first embodiment. At this time, a limiting plate extending outward is provided at one end of the outside of the cover body away from the mounting wall. The limiting plate is annular. A mating surface is formed on the side of the limiting plate facing the limiting rib. The end surface of the limiting rib abuts against the mating surface to form a planar fit, and the limiting rib is fixedly connected to the light guide cover. In this case, in order to simplify the structure of the housing, the limiting rib 130 in the first embodiment can be omitted.

[0059] It can be understood that in other embodiments of the present invention, two adjacent guide sleeves can also be connected by a connecting rib; or, two adjacent light guide covers are connected by a connecting rib, and two adjacent guide sleeves are connected by a connecting rib.

[0060] It can be understood that in other embodiments of the present invention, the guide sleeve can be fixed to the housing by a snap connection. At this time, the light guide cover does not need to be snap-connected to the wall of the housing. It only needs the cover body to abut against the inner side surface of the wall of the housing. Therefore, by using an integrally formed method, the light guide cover can also be fixed by relying on the installation of the guide sleeve, without the need to provide additional structures on the housing to fix the light guide cover, thus simplifying the structure of the housing.

[0061] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
