TECHNICAL FIELD
[0001] The present application relates to the technical field of cooking utensil detection structure, in particular to a door body, a steam oven, and a cooking utensil. BACKGROUND
[0002] There are many cooking utensils in the kitchen, and the inside of the cooking utensils needs to maintain a certain cooking environment during cooking. For example, an oven is usually in a high-temperature environment during cooking; a steam oven is usually in a high-temperature and high-humidity environment during cooking; and a microwave oven has a high microwave energy inside during cooking. The above-mentioned high temperature, high humidity, and high microwave energy are obtained in comparison with the kitchen environment space. The cooking environment generated during cooking is not conducive to direct human contact, so the working components such as heating elements and electromagnetic elements inside the cooking utensil work on the premise that the door body is in a closed state.
[0003] Therefore, the detection mechanism for detecting the opening and closing state of the door body is an important part of the cooking utensil.
[0004] Taking a steam oven as an example, the door body is movably connected to the steam oven body. The existing detection mechanism usually includes two parts, such as a pressure sensor and a travel switch, which are respectively arranged on the door body and the steam oven body. When the door body is closed, the sensor located between the door body and the steam oven body is stimulated to determine that the door body is closed. SUMMARY
[0005] The present application provides a door body, a steam oven, and a cooking utensil.
[0006] A door body comprises:
[0007] A connecting assembly is arranged in the door body and is used for connecting a cooking utensil. The connecting assembly has a first state when the door body is closed and a second state when the door body is opened.
[0008] A detection piece is connected to the connecting assembly. The detection piece is located at a first position when the connecting assembly is in the first state, and the detection piece is located at a second position when the connecting assembly is in the second state.
[0009] A detector is arranged in the door body. The detector comprises a detection end. The detection piece blocks the detection end when the detection piece is located at one of the first position and the second position.
[0010] The connecting assembly is a hinge assembly, and the hinge assembly comprises:
[0011] A hinge shell is arranged in the door body, and the detection piece is arranged in the hinge shell.
[0012] An elastic piece is arranged in the hinge shell.
[0013] A hinge transmission is movably connected in the hinge housing, and the detection member is connected with the hinge transmission and the elastic member.
[0014] The hinge housing is provided with:
[0015] A first rotating shaft, and the hinge transmission is rotatably connected in the first rotating shaft.
[0016] The hinge housing comprises:
[0017] A through hole, and the detection member is slidably connected in the through hole, and the through hole extends along the length direction of the hinge housing.
[0018] The detector and the detection member are respectively arranged on two sides of the through hole.
[0019] The door body comprises:
[0020] A first mounting area;
[0021] A second mounting area, and the connecting assembly and the detector are respectively arranged in the first mounting area and the second mounting area, and the second mounting area is provided with a detection opening, and the detection end of the detector is arranged corresponding to the detection opening.
[0022] The detector comprises a photoelectric emission end and a photoelectric receiving end, and the photoelectric emission end is arranged obliquely.
[0023] A steaming oven comprises:
[0024] An oven body, and one end of the oven body is open;
[0025] An inner container arranged in the oven body;
[0026] The door body in any of the above solutions is movably connected on the oven body, and the door body is used for closing the open end of the oven body.
[0027] A cooking appliance comprises:
[0028] An appliance body, and the appliance body comprises at least one opening, and the appliance body is provided with at least one inner cavity for forming a cooking environment corresponding to the opening;
[0029] The door body in any of the above solutions is movably connected on the appliance body, and the door body is used for closing the inner cavity.
[0030] The technical solution of the present application has the following advantages:
[0031] 1. The application provides a door body, comprising: a connecting assembly arranged in the door body and used for connecting a cooking appliance, the connecting assembly having a first state when the door body is closed and a second state when the door body is opened; a detection piece connected with the connecting assembly, the detection piece being located at a first position when the connecting assembly is in the first state and being located at a second position when the connecting assembly is in the second state; and a detector arranged in the door body, the detector comprising a detection end, the detection piece being located at one of the first position and the second position to shield the detection end.
[0032] The connecting assembly is arranged in the door body, and moves when the door body is opened and closed. The detection piece is connected with the connecting assembly and moves when the connecting assembly moves. The moving position of the connecting assembly changes when the door body switches between the first state and the second state. The connecting assembly has a stable moving path, and thus has a first position corresponding to the first state and a second position corresponding to the second state. Therefore, whether the detection piece reaches the corresponding detection position in the door body can be determined, that is, whether the door body is closed can be determined. The detector can be a travel switch, a pressure sensor or an optical emitter. The optical emitter emits rays to the detection position, and the rays are reflected back and received when the rays are shielded. The rays cannot be received when the rays are not shielded or are shielded at a non-detection position. Whether the door body is opened or not can be determined by judging whether the rays can be reflected back and received. The above actions and detection processes occur in the door body. The door body and the cooking appliance body are produced separately. In the prior art, the detection assembly arranged on the door body and the cooking appliance body needs to be debugged after the door body is installed. However, the door body adopting the present application only needs to be debugged when the door body is produced, thereby saving the detection step of debugging the detection assembly during the assembly of the whole machine and improving the assembly efficiency of the whole machine.
[0033] 2. The door body provided by the application, wherein the connecting assembly is a hinge assembly, the hinge assembly comprising: a hinge shell arranged in the door body, the detection piece being arranged in the hinge shell; an elastic piece arranged in the hinge shell; and a hinge transmission piece movably connected in the hinge shell, the hinge transmission piece being used for connecting the cooking appliance, the detection piece connecting the hinge transmission piece and the elastic piece.
[0034] The door body is movably connected to the cooking appliance through the hinge assembly, the detection assembly is arranged on the door body, one end of the elastic piece is connected to the hinge shell, and the other end of the elastic piece is connected to the door body through the detection piece and the hinge transmission piece. Therefore, when the door body is opened, the hinge transmission piece moves, the door body moves away from the cooking appliance to stretch the elastic piece, and the detection piece moves in the hinge shell to be displaced, so that the detection piece is located at different positions before the door body is opened.
[0035] 3. The door body provided by the present application, the hinge shell is internally provided with: a first rotating shaft, and the hinge transmission member is rotationally connected in the first rotating shaft.
[0036] The door body is rotationally opened, and the action of rotationally opening is transmitted to the detection member to trigger the movement of the detection member through the hinge transmission member.
[0037] 4. The door body provided by the present application, the hinge shell comprises: a through hole, and the detection member is slidingly connected on the through hole, and the through hole extends along the length direction of the hinge shell.
[0038] When the detection member is moved by the hinge transmission member, the detection member is limited by the through hole and thus slides along the length direction of the through hole. The detection member forms an occlusion to the through hole at one of the first position and the second position during the sliding process.
[0039] 5. The door body provided by the present application, the detector and the detection member are respectively arranged on two sides of the through hole.
[0040] When the detection member occludes the through hole, the detector is indirectly occluded and thus triggered to judge. Or the detection member leaves the through hole, and the detection member is away from the detector to eliminate the occlusion effect and trigger the detector to judge.
[0041] 6. The door body provided by the present application, the detector comprises a photoelectric emission end and a photoelectric receiving end, and the photoelectric emission end is obliquely arranged.
[0042] The rays emitted by the obliquely arranged photoelectric emission end have a certain oblique angle, and when the rays are occluded, the rays can return at the same oblique angle and thus be accurately received by the photoelectric receiving end. When the occlusion is lost or the occlusion position is not at the set position, the rays still cannot be accurately received by the photoelectric receiving end. BRIEF DESCRIPTION OF DRAWINGS

[0056] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0057] Example 1
[0058] This embodiment provides a door body 2, such as Figure 1 As shown, the system includes: a connecting component disposed within the door 2 for connecting cooking utensils; the connecting component having a first state when the door 2 is closed and a second state when the door 2 is open; a detection element 32 connected to the connecting component; the detection element 32 being located in a first position when the connecting component is in the first state and in a second position when the connecting component is in the second state; and a detector 4 disposed within the door 2, the detector 4 including a detection end, which is obstructed when the detection element 32 is in either the first or second position. By providing the connecting component within the door 2, when the door 2 performs opening and closing actions, the connecting component moves under the pull of these actions. The detection element 32, connected to the connecting component, also moves under the pull of the connecting component's movement. The movement position of the connecting component changes as the door 2 switches between its first and second states. The connecting component has a stable movement path, thus having a first position corresponding to the first state and a second position corresponding to the second state. Therefore, by detecting whether the detection element 32 reaches the corresponding detection position within the door 2, it can be determined whether the door 2 is closed. The detector 4 can be a limit switch, pressure sensor, or photoelectric emitter. It emits a beam of light to the detection position; if the beam is blocked, it is reflected back and received. If the beam is not blocked or is blocked outside the detection position, it cannot be received. The openness of the door 2 is determined by whether the beam is reflected back and received. All the above actions and detection processes occur inside the door 2. The door 2 and the cooking appliance body 1 are manufactured separately. In existing technologies, detection components are separately installed on the door 2 and the cooking appliance body 1, requiring adjustment after the door 2 is installed. However, with this solution, the door 2 only needs to be adjusted during its production, saving the detection component adjustment steps during overall assembly and improving assembly efficiency.
[0059] The door body 2 of the embodiment can also be installed on a microwave oven or other cooking appliance. As an alternative embodiment, the door body 2 of the embodiment can also be applied to a dishwasher, a refrigerator or other equipment, so that the opening and closing state of the door body 2 can be accurately detected. The cooking appliance structure shown in the drawings is a single-chamber structure. The cooking appliance usually has an inner container 11, and the door body 2 is used to close the inner container to form a sealed chamber structure, and thus can be applied to the closure of a multi-chamber structure. As an alternative embodiment, a single chamber can also be closed by a plurality of door bodies 2 of the embodiment, and the door body 2 can still detect the opening and closing of the door body 2 when the door body 2 performs the opening and closing action, and the detection member 32 inside the door body 2 is displaced by the above action, so that the above action is detected.
[0060] The embodiment detects the change of the position of the detection member 32 to determine the opening and closing state of the door body 2. The way to determine the change of the position of the detection member 32 can also be that a pressure sensor is arranged in the door body 2, and the pressure sensor is arranged at least at one of the first position or the second position. The movement of the detection member 32 triggers the pressure sensor to indicate that the door body 2 is opened or closed.
[0061] The structure of the connecting assembly is not limited, such as Figure 2 Figure 4 As shown, the connecting assembly is a hinge assembly 3, which includes a hinge housing 31 arranged in the door body 2, the detection member 32 is arranged in the hinge housing 31, a resilient member 34 arranged in the hinge housing 31, a hinge transmission member 33 movably connected in the hinge housing 31, the hinge transmission member 33 is used to connect the cooking appliance, and the detection member 32 is connected to the hinge transmission member 33 and the resilient member 34. The door body 2 is movably connected to the cooking appliance through the hinge assembly 3, the detection assembly is arranged on the door body 2, one end of the resilient member 34 is connected to the hinge housing 31, and the other end of the resilient member 34 is connected to the door body 2 through the detection member 32 and the hinge transmission member 33. Therefore, when the door body 2 is opened, the hinge transmission member 33 moves, the door body 2 moves away from the cooking appliance to stretch the resilient member 34, the detection member 32 is pulled by the resilient member 34 to move in the hinge housing 31 to be displaced, so that the detection member 32 is located at different positions before the door body 2 is opened. As an alternative embodiment, the connecting assembly is a sprocket and chain, as shown in Figure 4 The hinge transmission member 33 is replaced by a sprocket, another driven sprocket is arranged above the hinge housing 31, and a chain is used to connect the two sprockets. When the door body 2 is opened or closed, the sprocket rotates to drive the chain to rotate, the detection member 32 is arranged on the chain, and the detection member 32 is displaced along the chain, so that the opening and closing of the door body 2 can still be detected. As another alternative embodiment, the connecting assembly is a pulley transmission belt structure.
[0062] The connection between the door body 2 and the appliance body 1 is not specifically limited. In the embodiment, as shown in Figure 1 The hinge shell 31 is provided with a first rotating shaft 311, and the hinge transmission member 33 is rotationally connected in the first rotating shaft 311. The door body 2 is rotationally connected with the appliance body 1, and the door body 2 is rotationally opened. The hinge transmission member 33 transmits the action of rotationally opening to the detection member 32 to trigger the movement of the detection member 32. As an alternative embodiment, the door body 2 is slidingly connected with the appliance body 1.
[0063] On the basis of the above-mentioned embodiment, as a further defined embodiment, as shown in Figure 4 Figure 6 The hinge shell 31 includes a through hole 313, and the detection member 32 is slidingly connected with the through hole 313. The through hole 313 extends along the length direction of the hinge shell 31. When the detection member 32 is moved by the hinge transmission member 33, the detection member 32 is limited by the through hole 313 and slides along the length direction of the through hole 313. The detection member 32 forms an obstruction to the through hole 313 at one of the first position and the second position during the sliding along the through hole 313.
[0064] Specifically, in Figure 4 When the door body 2 is opened, the hinge shell 31 moves away from the appliance body 1 along with the door body 2, the elastic member 34 is stretched, the detection member 32 is limited by the second sliding shaft 322 and slides along the through hole 313, and the position of the original obstruction to the through hole 313 is moved away, Figure 4 As shown in the embodiment, the spring is stretched to the through hole 313. Since the spring cannot obstruct the through hole 313, according to the characteristics of the straight-line propagation of light, the rays cannot be reflected at the set position, and the photoelectric receiving end 42 cannot receive the reflected rays.
[0065] On the basis of the above-mentioned embodiment, as a further defined embodiment, as shown in Figure 4 The detection member 32 is provided with a first sliding shaft 321 and a second sliding shaft 322, and the hinge shell 31 is provided with a through hole 313 for the sliding of the first sliding shaft 321 and the second sliding shaft 322. Since the first sliding shaft 321 and the second sliding shaft 322 are cylindrical shafts in the embodiment, in order to prevent the detection member 32 from rotating, two sliding shafts are adopted in the embodiment. As an alternative embodiment, the detection member 32 is only slidingly connected with the first sliding shaft 321 and the through hole 313, and the cross section of the first sliding shaft 321 is a polygon. As shown in Figure 4 As shown, the elastic member 34 is connected to the second sliding shaft 322, and the hinge transmission member 33 is connected to the first sliding shaft 321. In this embodiment, the elastic member 34 is a tension spring. Specifically, the hinge housing 31 has a fixing member 312, and the tension spring 34 is connected to the fixing member 312.
[0066] On the basis of the above-mentioned embodiments, as further defined embodiments, as shown in Figure 2 、 Figure 5 、 Figure 6 As shown, the detector 4 and the detection member 32 are respectively arranged on both sides of the through hole 313. When the detection member 32 blocks the through hole 313, the detector 4 is indirectly blocked, thereby triggering the judgment of the detector 4. Or the detection member 32 leaves the through hole 313, and the detection member 32 is away from the detector 4 to eliminate the blocking effect, thereby triggering the judgment of the detector 4.
[0067] On the basis of the above-mentioned embodiments, as further defined embodiments, as shown in Figure 2 、 Figure 5 、 Figure 6 As shown, the door body 2 comprises a first mounting area 22 and a second mounting area 23. The connecting assembly and the detector 4 are respectively located in the first mounting area 22 and the second mounting area 23. The second mounting area 23 is provided with a detection port 231, and the detection end of the detector 4 is arranged corresponding to the detection port 231.
[0068] Specifically, as shown in Figure 2 、 Figure 5 The side of the door body 2 facing the cooking utensil cavity is an inner panel 21, and the side opposite to the inner panel 21 is an outer panel 24. The inner panel 21 and the outer panel 24 form an internal space of the door body 2 with a certain thickness. The two sides of the internal space of the door body 2 are strip-shaped first mounting areas 22, and the hinge assembly 3 is arranged in the first mounting areas 22 in this embodiment. The second mounting area 23 is located at the middle position of the internal space of the door body 2. When some cooking utensils need to be provided with a touch screen, a display screen or the like on the door body 2, the second mounting area 23 can provide mounting positions for the above-mentioned components themselves and the matching circuits of the above-mentioned components.
[0069] On the basis of the above-mentioned embodiments, as further defined embodiments, as shown in Figure 5 - Figure 7 As shown, the detector 4 comprises a photoelectric emission end 41 and a photoelectric receiving end 42, and the photoelectric emission end 41 is arranged obliquely. The rays emitted by the obliquely arranged photoelectric emission end 41 have a certain oblique angle, and when the rays are blocked, they can return at the same oblique angle, thereby being accurately received by the photoelectric receiving end 42. When the blocking is lost or the blocking position is not at the set position, the rays still cannot be accurately received by the photoelectric receiving end 42.
[0070] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and can not be enumerated. The obvious changes or variations derived from the above description are still within the protection scope of the present application.
