Description

Technical Field

[0001] The utility model relates to the technical field of gas cookers, in particular to a probe assembly. Background Art

[0002] The common anti-dry-burn protector on the market is a spring device set in the center of the gas stove. The elastic force of the spring presses the temperature sensor against the bottom of the pot. The temperature sensor usually uses NTC active heat source tracking technology to intelligently detect the dry-burning status of the pot.

[0003] When using the gas stove, if you forget to turn off the fire during high heat heating and the bottom of the pot is overheated, when it exceeds the protection warning temperature, the anti-dry burning overheat protection device will be activated, a continuous buzzer alarm will be issued and the gas will be cut off to avoid fires caused by dry pots and other safety accidents. If the fire is burning for a period of time without placing the pot, the intelligent fire-off function will be activated, a long alarm will be issued and the gas will be cut off to save gas and ensure safety.

[0004] However, the existing anti-dry-burn gas stove probe is generally designed to be mechanically pressed down, and the spring keeps it in the pop-up state when there is no pressure. When the user is frying or flipping the pan, the probe is in the pop-up state, which is easy to trigger the anti-dry-burn. In addition, when the user flips the pan, the probe will collide with it, which is very easy to damage the probe and affect the user experience. Utility Model Content

[0006] The utility model solves the above technical problems through the following technical solutions:

[0007] A probe assembly is used for a cooker, the probe assembly comprising a detection probe, an electromagnetic part and an armature;

[0008] The detection probe is arranged in a vertical direction and is located inside the burner of the cooker, and is used to detect the state of the pot above the burner;

[0009] The electromagnetic part is connected to the bottom of the burner;

[0010] The armature is arranged in the electromagnetic part and connected with the detection probe, so that when the electromagnetic part is energized, the armature can drive the detection probe to move downward to the retracted position.

[0011] In the present solution, an electromagnetic part and an armature are provided, and the electromagnetic part is used to control the armature to move up and down, thereby indirectly driving the detection probe connected to the armature to move downward, and the detection probe is retracted when moving downward, thereby avoiding continuous exposure of the detection probe and protecting the detection probe; the probe assembly allows the user to actively control the detection probe to fully retract, thereby better adapting to the situation of overturning the pot, providing a better user experience, and better protecting the detection probe; in addition, the detection probe is arranged in the burner in a vertical direction, and the electromagnetic part is arranged at the bottom of the burner, so that the detection probe and the electromagnetic part are easy to connect and better adapt to the structural characteristics of ordinary stove burners.

[0012] Preferably, the probe assembly includes a reset member, which is connected to the detection probe and applies an upward force to the detection probe, so that when the electromagnetic part is powered off, the reset member is used to drive the detection probe to move upward to the detection position.

[0013] In this solution, by providing a reset member connected to the detection probe, the detection probe can be moved up and back to the detection position, ensuring that the probe can perform normal detection functions.

[0014] Preferably, the detection probe comprises a slide bar, the slide bar is arranged in a vertical direction, and the lower end of the slide bar is fixedly connected to the armature.

[0015] In this solution, by setting a sliding rod along the vertical direction, it can better adapt to the needs of the probe assembly sliding up and down, and further adapt to the structural characteristics of ordinary stove burners, saving the space occupied by the assembly; the armature is fixed to the lower end of the sliding rod, and the lower half of the sliding rod and the armature can be hidden inside the stove, which is practical and beautiful, and can protect the assembly.

[0016] Preferably, the sliding rod includes a limiting portion, which is connected to the rod body of the sliding rod and protrudes relative to the rod body in a radial direction of the rod body. The reset member is a first spring, which is sleeved outside the sliding rod, and the upper end of the first spring abuts against the limiting portion, and the lower end is fixed relative to the electromagnetic part.

[0025] Preferably, the limiting portion of the slide rod comprises a flange with a spline, and the inner wall of the sleeve comprises a groove matched with the flange, and the groove is used to limit the circumferential rotation of the slide rod relative to the sleeve.

[0029] In the present solution, a mounting base plate is provided for the probe assembly so that the aforementioned electromagnetic part, sleeve, spring and other structures can be connected and installed on the cooker, making the connection between the structures more stable and reliable, and the entire probe assembly can be fixed by fixing the mounting base plate during installation, which is more convenient; and a limiting hole is opened in the mounting base plate so that the armature can pass through it and slide up and down, which not only meets the movement requirements of the armature, but also plays a limiting role.

[0030] A stove comprises the probe assembly as described in any of the above schemes, wherein the detection probe is a temperature sensor, and the temperature sensor is electrically connected to an anti-dry-burning controller of the stove.

[0031] In this solution, a temperature sensor is used as a detection probe and is electrically connected to an anti-dry-burning controller, providing a solution for a stove that implements an anti-dry-burning function by taking the detected temperature state of a pot as an example.

[0057] Burner 9 DETAILED DESCRIPTION

[0058] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0059] The utility model discloses a probe assembly for a cooker. Figure 1 FIG. 1 is a cross-sectional view of a probe assembly according to an embodiment of the present invention. Figure 1As shown, the probe assembly includes a detection probe 1, an electromagnetic part 2 and an armature 3; the detection probe 1 is arranged in the vertical direction and is located in the burner 9 of the cooker, and is used to detect the state of the pot above the burner 9; the electromagnetic part 2 is connected to the bottom of the burner 9; the armature 3 is arranged in the electromagnetic part 2 and connected to the detection probe 1, so that when the electromagnetic part 2 is energized, the armature 3 can drive the detection probe 1 to move down to the retracted position. The utility model sets the electromagnetic part 2 and the armature 3, and uses the electromagnetic part 2 to control the armature 3 to move up and down, and indirectly drives the detection probe 1 connected to the armature 3 to move down, and realizes the retraction of the detection probe 1 when moving down, so as to avoid the detection probe 1 from being continuously exposed, thereby protecting the detection probe 1. The probe assembly allows the user to actively control the detection probe 1 to fully retract, better adapt to the situation of flipping the pot, better user experience, and better protection effect on the detection probe 1.

[0060] The probe assembly is assembled in the burner 9 as follows: Figure 7 As shown, the detection probe 1 is arranged in the burner 9 along the vertical direction, and the electromagnetic part 2 is arranged at the bottom of the burner 9, so that the detection probe 1 and the electromagnetic part 2 are easy to connect and better adapt to the structural characteristics of the ordinary stove burner 9. Those skilled in the art should note that Figure 7 The specific structure and shape of the probe assembly shown in the figure are only used as examples to illustrate the setting position of the probe assembly of the utility model in the burner 9, and should be adaptively adjusted during actual implementation.

[0061] In this embodiment, the probe assembly includes a reset member, which is connected to the detection probe 1 and applies an upward force to the detection probe 1, so that when the electromagnetic part 2 is powered off, the reset member is used to drive the detection probe 1 to move up to the detection position. This solution adds a probe reset function on the basis of the probe retraction function, so that the probe can rise and perform normal detection. Among them, the reset member can be selected from a variety of commonly used driving mechanisms in the field, such as a reset spring, an electromagnet, a linear motor, etc. The reset member selected in this embodiment will be further described in detail below as a preferred embodiment in conjunction with the accompanying drawings.

[0062] Figure 2 for Figure 1 The enlarged partial cross-sectional view of the circled part of the probe assembly shown in the figure shows that the detection probe 1 includes a slide bar 11, which is arranged in the vertical direction, and the lower end of the slide bar 11 is fixedly connected to the armature 3. By arranging the slide bar 11 in the vertical direction, this embodiment better meets the requirements of the probe assembly sliding up and down, and further meets the structural characteristics of the burner 9 of the ordinary stove, saving the space occupied by the assembly; the armature 3 is fixed to the lower end of the slide bar 11, and the lower half of the slide bar 11 and the armature 3 can be hidden inside the stove, which is practical and beautiful, and can protect the assembly.

[0063] The armature 3 shown in this embodiment is connected to the lower end of the slide bar 11, which is set to match the position of the slide bar 11-shaped detection probe 1 and the electromagnetic part 2 at the bottom of the burner 9. Its connection method is a preferred embodiment of the utility model. In the actual implementation process, the detection probe 1 can be set to other shapes, and the connection position of the armature 3 and the detection probe 1 can be appropriately adjusted; or the armature 3 can be connected to other positions such as the side of the rod body of the slide bar 11. These adjustment methods will not cause the main technical effect of the armature 3 driving the detection probe 1 to move to be lost.

[0064] like Figure 2 As shown, the slide bar 11 includes a limiting portion 111, which is connected to the rod body of the slide bar 11 and protrudes relative to the rod body in the radial direction of the rod body. The reset member is a first spring 4, which is sleeved outside the slide bar 11, and the upper end of the first spring 4 abuts against the limiting portion 111, and the lower end is fixed relative to the electromagnetic part 2. In this embodiment, the limiting portion 111 is set on the rod body of the slide bar 11, and the first spring 4 is selected as the reset member. The spring structure is easy to match with the slide bar 11, and can be as shown in FIG. Figure 2 As shown, it is sleeved outside the slide rod 11 to reduce the space occupied by the entire probe assembly; the first spring 4 is abutted against the limit portion 111, and when the electromagnet is powered off, the elastic force of the spring can be used to push the slide rod 11 upward. The first spring 4 can make the detection probe 1 move upward under the push of the cookware to achieve a reset function.

[0065] like Figure 1 , Figure 2 As shown, the armature 3 of this embodiment is coaxially arranged with the slide bar 11, and the armature 3 also includes an axial central through hole 31, and the wire 5 connected to the lower end of the slide bar 11 is passed through the central through hole 31. The armature 3 is coaxially arranged with the slide bar 11 and a hole is dug in the armature 3 to pass the wire 5, so that the wire 5 can be electrically connected to the detection probe 1. This structure further reduces the occupied space of the entire probe assembly, and the armature 3 has a protective effect on the wire 5, and the wire 5 is not easy to bend and damage. This embodiment adapts to the connection position of the slide bar 11 and the armature 3, and the position of the wire 5 can be set as needed during actual implementation.

[0066] The probe assembly of this embodiment further includes a sleeve 6, such as Figure 2 As shown, the sleeve 6 is coaxially sleeved outside the slide bar 11, and the limiting portion 111 and the first spring 4 are both located inside the sleeve 6; the sleeve 6 wall protects the slide bar 11, and at the same time, the upper end wall 61 of the sleeve 6 limits the axial upward movement distance of the limiting portion 111 on the slide bar 11, which can prevent the detection probe 1 from extending too long from the cooker. In addition, the sleeve 6 has an upper end wall 61, and the detection end 112 of the slide bar 11 passes through the upper end wall 61 of the sleeve 6 and extends out of the upper end wall 61 to ensure that the detection end 112 can fully detect the external cooker condition.

[0067] The sleeve 6 provided in this embodiment can be selectively replaced with a protective shell or the sleeve 6 can be removed during actual implementation. The protective effect and the movement stability of the component may be affected, but the main technical effect will not be lost.

[0068] like Figure 2 As shown, a second spring 7 is provided between the limit portion 111 and the upper end wall 61, and the two ends of the second spring 7 are respectively in contact with the limit portion 111 and the upper end wall 61, so as to realize buffering and shock reduction in the process of the slide bar 11 moving to the detection position, so as to adapt to the situation that the detection probe 1 is more delicate and fragile, and make the overall movement stability better. In addition, when the electromagnet is powered off, the second spring 7 cooperates with the first spring 4, so that the detection probe 1 can be passively moved up and down under the push of the pot, further improving the position adaptation ability. And, similar to the first spring 4, the second spring 7 is sleeved outside the slide bar 11 and located in the sleeve 6. As can be seen from the figure, the overall structure of the probe assembly of this embodiment is compact, occupies a small space, and is easy to be hidden in the cooker.

[0069] Preferably, the limiting portion 111 of the slide bar 11 includes a flange with splines, and the inner wall of the sleeve 6 includes a groove 62 matched with the flange, and the groove 62 is used to limit the circumferential rotation of the slide bar 11 relative to the sleeve 6.

[0070] This embodiment further optimizes the movement stability of the slide bar 11 . Figure 4 This is a three-dimensional structural diagram of the slide bar 11 of the probe assembly of an embodiment of the utility model. Figure 3 6 is a three-dimensional structural diagram of the sleeve 6 that cooperates therewith. It can be seen that the limiting portion 111 of this embodiment is a flange with a spline, and the inner wall of the sleeve 6 is provided with a groove 62 of a corresponding shape. The flange cooperates with the groove 62 to prevent the slide bar 11 from rotating relative to the sleeve 6, thereby improving the movement stability of the slide bar 11. Alternatively, the shape of the groove 62 can be changed to make the slide bar 11 rotate and move along the desired fixed track.

[0071] In order to further improve the compatibility of the probe assembly with the stove burner 9, the probe assembly disclosed in this embodiment includes a mounting base plate 8, so that the aforementioned electromagnetic part 2, sleeve 6, spring and other structures are connected and installed on the stove, so that the connection between the structures is more stable and reliable, and the entire probe assembly can be fixed by fixing the mounting base plate 8 during installation, which is more convenient. Figure 7 As shown, the mounting base plate 8 is fixed to the bottom of the burner 9 and is fixedly connected to the upper end of the electromagnetic part 2 and the lower end of the sleeve 6 respectively, and the lower end of the first spring 4 abuts against the mounting base plate 8.

[0072] Figure 5This is a schematic diagram of the coordination between the mounting base plate 8 and the electromagnetic part 2. The mounting base plate 8 shown in the figure includes a limiting hole 81. The armature 3 is passed through the limiting hole 81 along the direction of the white arrow and can slide up and down, which not only meets the movement requirements of the armature 3, but also plays a limiting role. Figure 6 It is a three-dimensional assembly diagram of the probe assembly including the mounting base plate 8.

[0073] The utility model also provides a stove, Figure 8 This is a stereoscopic diagram of a probe assembly of an embodiment of the utility model installed in a burner 9 of a stove. The stove includes a probe assembly as in any of the above-mentioned schemes, and the detection probe 1 is a temperature sensor, and the temperature sensor is electrically connected to the anti-dry-burning controller of the stove.
