Description

Technical Field

[0001] The utility model relates to kitchen appliances, in particular to a frying and roasting machine. Background Art

[0002] In the prior art, the temperature-adjustable grilling machine generally adopts electronic type, which is relatively expensive. Therefore, there is also a prior art such as utility model patent CN201920068816.6, which discloses a grilling machine with convenient temperature control. A sudden jump thermostat is selected. The temperature sensing contact at the top of the sudden jump thermostat contacts the baking pan. The sudden jump thermostat is provided with an axially floating control shaft. The knob is set on the panel. The knob can be connected to the control shaft through the transmission of three gears, namely the driving gear, the transition gear and the driven gear, to adjust the trigger temperature of the sudden jump thermostat, resulting in a large distance between the knob and the control shaft and a relatively complex structure. In addition, the electric heating tube in the above grilling machine is arranged in a ring shape, and the sudden jump thermostat is arranged in the inner ring of the electric heating tube. The baking pan located in the inner ring of the electric heating tube will heat up faster than the baking pan located outside the electric heating tube, resulting in the sudden jump thermostat easily controlling the heating tube to stop heating in advance, so that the temperature of the baking pan located outside the electric heating tube is lower than the set temperature, affecting the baking effect. Utility Model Content

[0003] The utility model aims to provide a grilling machine, which overcomes the shortcomings of the prior art, not only makes the temperature control of the sudden jump type thermostat more accurate and ensures the baking effect, but also simplifies the temperature control structure.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a grilling machine, including a grilling tray assembly, the grilling tray assembly including a base and a grilling tray arranged on the base, a heating tube, a sudden jump type thermostat, and a knob, the sudden jump type thermostat is provided with an axially floating control shaft, the knob adjusts the triggering temperature of the sudden jump type thermostat through the control shaft, the sudden jump type thermostat is located on the periphery of the heating tube, the knob is provided with a driving gear, the control shaft is provided with a driven gear, and the knob drives the control shaft to rotate by the engagement of the driving gear and the driven gear.

[0005] After adopting the above technical scheme, the utility model has the following advantages: first, the sudden jump thermostat is arranged on the periphery of the heating tube, so that the sudden jump thermostat controls the heating tube to stop heating only after the baking tray on the periphery is heated to the preset temperature, so as to ensure the whole baking tray can reach the preset temperature, thereby ensuring the baking effect, and also can reduce the temperature of the environment in which the sudden jump thermostat is located, thereby ensuring the service life of the sudden jump thermostat, and, because the sudden jump thermostat is arranged on the periphery of the heating tube, the distance between the sudden jump thermostat and the knob is closer, thereby simplifying the temperature control structure, and only needs to set a secondary gear combination of the driving gear and the driven gear, so as to eliminate the influence of the up and down movement of the control shaft on the knob when rotating, so as to make the gap between the knob and the base smaller, and the overall appearance is more beautiful.

[0006] Furthermore, the grill pan assembly also includes a partition plate that divides the base into an upper heating space and a lower installation space, the grill pan and the heating tube are installed in the heating space, and the sudden jump thermostat is installed in the installation space. The aforementioned technical solution is adopted, and the base is divided into an upper heating space and a lower installation space by setting a partition plate, the grill pan and the heating tube are installed in the heating space, and the sudden jump thermostat is installed in the installation space. The partition plate effectively isolates the heat of the heating tube from being directly transferred to the sudden jump thermostat, making the temperature control of the sudden jump thermostat more accurate. The partition plate can also make the temperature of the installation space lower, thereby ensuring the service life of the sudden jump thermostat.

[0007] Furthermore, a heat-conducting column protruding toward the installation space is provided on the baking tray in the peripheral area of ​​the heating tube, and a through hole is provided on the partition plate for the heat-conducting column to pass through and fixedly connected to the sudden jump thermostat. According to the above technical solution, a heat-conducting column protruding toward the installation space is provided on the baking tray in the peripheral area of ​​the heating tube, and the contact between the heat-conducting column and the sudden jump thermostat replaces the direct contact between the baking tray and the sudden jump thermostat. The sudden jump thermostat detects the heat transferred from the baking tray to the heat-conducting column by heat conduction for control. The temperature control of the sudden jump thermostat is more accurate, which effectively reduces the interference of the baking tray in the form of heat radiation on the sudden jump thermostat detection and the interference of the heating tube on the sudden jump thermostat detection.

[0008] Furthermore, the sudden jump thermostat includes a temperature sensing body and a heat conducting plate, the temperature sensing body and the heat conducting plate are fixedly connected, the heat conducting plate is fixedly connected to the heat conducting column, and the temperature sensing body is installed on the heat conducting column through the heat conducting plate to sense the temperature of the baking tray. By adopting the above technical solution, the heat conducting plate is fixedly connected to the heat conducting column to realize the installation of the sudden jump thermostat, and the heat of the heat conducting column can also be transferred to the temperature sensing body through the heat conducting plate, which is conducive to ensuring the accuracy of the temperature control of the sudden jump thermostat while avoiding the temperature sensing body from directly contacting the heat conducting column with a higher temperature, thereby ensuring the service life of the temperature sensing body.

[0009] Furthermore, the heat conducting plate extends toward the side of the heat conducting column away from the heating tube, so that the temperature sensing body is away from the heating tube. Through the above technical solution, the heat conducting plate extends toward the side of the heat conducting column away from the heating tube, so that the temperature sensing body is further away from the heating tube, further reducing the interference of the heating tube on the temperature sensing of the sudden jump thermostat.

[0010] Furthermore, the partition plate is raised upward to form a clearance space in the installation space to avoid the jump-type thermostat. Through the above technical solution, the partition plate is raised upward to form a clearance space in the installation space, which meets the installation requirements of the jump-type thermostat and can also make the structure of the grill more compact.

[0011] Furthermore, the driving gear includes a gear shaft and a gear part, the gear shaft is fixedly connected to the gear part and is located on the top side of the gear part, the knob is fixedly connected to the gear shaft, and the base is provided with a first limiting rib corresponding to the top of the gear part and a pressing plate corresponding to the bottom of the gear part, the pressing plate presses the gear part against the first limiting rib to limit the axial movement of the gear part. Through the above technical solution, the gear shaft is fixedly connected to the gear part, and the pressing plate presses the gear part against the first limiting rib to limit the axial movement of the gear part, thereby avoiding the knob fixedly connected to the gear shaft from moving, which is beneficial to reducing the gap between the knob and the base, and the overall appearance is more beautiful.

[0012] Furthermore, the first limiting convex rib is provided with a through hole for the gear shaft to pass through, and the first limiting convex rib is arranged around the gear shaft. Through the above technical solution, since the gear shaft is fixedly connected to the gear part and is located on the top side of the gear part, the first limiting convex rib is provided with a through hole for the gear shaft to pass through, so that the installation of the gear shaft is met, and the first limiting convex rib is arranged around the gear shaft, which forms a better limiting effect on the gear part and effectively avoids the gear part from tilting.

[0013] Furthermore, a heat-insulating gap is provided between the knob and the outer surface of the base, and the axial dimension of the heat-insulating gap is D, D≤1mm. With the above technical solution, by providing the heat-insulating gap, the heat on the base is not easily transferred to the knob, which effectively avoids the user's hands from getting hot when using the knob, and is also conducive to ensuring that the user does not touch the base when using the knob, making it safer to use. If the heat-insulating gap between the knob and the base is greater than 1mm, the gap between the knob and the base is large, affecting the aesthetics.

[0014] Furthermore, the driven gear is located above the sudden jump thermostat, and a second limiting rib corresponding to the top of the driven gear is provided on the base, and the second limiting rib is used to locate the end point of the upward movement of the driven gear. With the above technical solution, the driven gear is located above the sudden jump thermostat. Since the sudden jump thermostat will drive the driven gear to jump upward during the temperature control process, the second limiting rib corresponding to the top of the driven gear is provided on the base to locate the end point of the upward movement of the driven gear, thereby avoiding the driven gear from being out of mesh with the driving gear due to excessive movement, and reducing the occurrence of temperature control failures.

[0033] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0034] like Figures 1 to 11 As shown, the utility model provides a grilling machine, including a grilling pan assembly, the grilling pan assembly including a cover body 3, a base 1 and a grilling pan 2 arranged on the base 1, a heating tube 4, a sudden jump type thermostat 5, and a knob 6. The sudden jump type thermostat 5 is provided with an axially floating control shaft 51, the knob 6 adjusts the triggering temperature of the sudden jump type thermostat 5 through the control shaft 51, the sudden jump type thermostat 5 is located at the periphery of the heating tube 4, the knob 6 is provided with a driving gear 7, the control shaft 51 is provided with a driven gear 8, and the knob 6 drives the control shaft 51 to rotate by the engagement of the driving gear 7 with the driven gear 8.

[0035] With such a design, the sudden jump thermostat 5 controls the heating tube 4 to stop heating only after the outer baking tray 2 is heated to the preset temperature, so as to ensure that the entire baking tray 2 can reach the preset temperature, thereby ensuring the baking effect. The temperature of the environment in which the sudden jump thermostat 5 is located can also be reduced to ensure the service life of the sudden jump thermostat 5. In addition, since the sudden jump thermostat 5 is arranged on the periphery of the heating tube 4, the distance between the sudden jump thermostat 5 and the knob 6 is closer, which simplifies the temperature control structure. Only a secondary gear combination of the driving gear 7 and the driven gear 8 needs to be set, which can eliminate the influence of the up and down movement of the control shaft 51 on the knob 6 when it rotates, so that the gap between the knob 6 and the base 1 is smaller, and the overall appearance is more beautiful.

[0036] It should be noted that the preset temperature is a range value.

[0037] It should be noted that the knob 6 can be arranged on the top of the base 1 or on the side wall of the base 1 .

[0038] When in use, the preset temperature of the sudden jump thermostat 5 is set by the knob 6 to ensure that the temperature of the baking tray 2 is always at the preset temperature. After that, the sudden jump thermostat 5 controls the heating tube 4 to be powered on and heat up, and monitors the temperature of the baking tray 2 in real time. Finally, the start and stop of the heating tube 4 is controlled by sensing the temperature of the baking tray 2. When the temperature of the baking tray 2 is higher than the upper limit of the preset temperature, the sudden jump thermostat 5 cuts off the power supply of the heating tube 4, so that the heating tube 4 no longer generates heat, and the temperature of the baking tray 2 will decrease over time. When the temperature of the baking tray 2 is lower than the lower limit of the preset temperature, the sudden jump thermostat 5 resumes the power supply to the heating tube 4 to ensure the required temperature for baking food, so as to ensure the baking effect. The user can also adjust the preset temperature of the sudden jump thermostat 5 by rotating during the baking process according to actual baking needs.

[0039] Since the temperature of the air around the heating tube 4 and the baking tray 2 is relatively high, the traditional sudden jump type thermostat 5 is in direct contact with the baking tray 2, and the sudden jump type thermostat 5 is easily heated by the air, resulting in the detected temperature being easily higher than the actual situation of the baking tray 2, and the sudden jump type thermostat 5 is prone to premature tripping. To this end, the baking tray 2 assembly also includes a partition plate 13 that divides the base 1 into an upper heating space 11 and a lower installation space 12, the baking tray 2 and the heating tube 4 are installed in the heating space 11, and the sudden jump type thermostat 5 is installed in the installation space 12. In this design, by setting the partition plate 13, the base 1 is divided into an upper heating space 11 and a lower installation space 12, the baking tray 2 and the heating tube 4 are installed in the heating space 11, and the sudden jump type thermostat 5 is installed in the installation space 12. The partition plate 13 effectively isolates the heat of the heating tube 4 from being directly transferred to the sudden jump type thermostat 5, so that the temperature control of the sudden jump type thermostat 5 is more accurate, and the partition plate 13 can also make the temperature of the installation space 12 lower, thereby ensuring the service life of the sudden jump type thermostat 5.

[0040] Furthermore, a heat-conducting column 21 protruding toward the installation space 12 is provided on the baking tray 2 in the peripheral area of ​​the heating tube 4, and a through hole 131 is provided on the partition plate 13 for the heat-conducting column 21 to pass through and fixedly connected to the sudden jump thermostat 5. With such a design, the contact between the heat-conducting column 21 and the sudden jump thermostat 5 replaces the direct contact between the baking tray 2 and the sudden jump thermostat 5, and the sudden jump thermostat 5 detects the heat transferred to the heat-conducting column 21 by the baking tray 2 in the form of heat conduction for control, and the temperature control of the sudden jump thermostat 5 is more accurate, effectively reducing the interference of the baking tray 2 in the form of heat radiation on the sudden jump thermostat 5 detection and the interference of the heating tube 4 on the sudden jump thermostat 5 detection. Among them, the heat-conducting column 21 passing through the through hole 131 can also play a positioning role when the baking tray 2 is installed on the base 1, so that the installation position of the baking tray 2 is more accurate.

[0041] Since the control shaft 51 will float axially during the temperature control process of the sudden jump type temperature control, the partition plate 13 is raised upward to form an escape space 14 for escaping the sudden jump type temperature control device 5 in the installation space 12. Such a design satisfies the installation and operation of the sudden jump type temperature control device and can also make the grilling machine more compact.

[0042] The driven gear 8 is located above the jump-type thermostat 5, and the driven gear 8 will float axially with the control shaft 51. For this reason, the base 1 is provided with a second limit rib 17 corresponding to the top of the driven gear 8, and the second limit rib 17 is used to locate the end point of the upward movement of the driven gear 8. With such a design, the second limit rib 17 locates the end point of the upward movement of the driven gear 8, thereby preventing the driven gear 8 from moving too much and disengaging from the driving gear 7, thereby reducing the occurrence of temperature control failures.

[0043] The sudden jump thermostat 5 includes a temperature sensing body 52 and a heat conducting plate 53, the temperature sensing body 52 and the heat conducting plate 53 are fixedly connected, the heat conducting plate 53 is fixedly connected to the heat conducting column 21, and the temperature sensing body 52 is installed on the heat conducting column 21 through the heat conducting plate 53 to sense the temperature of the baking tray 2. With such a design, the sudden jump thermostat 5 is installed, and the heat of the heat conducting column 21 can also be transferred to the temperature sensing body 52 through the heat conducting plate 53, which is conducive to ensuring the accuracy of the temperature control of the sudden jump thermostat 5 while avoiding the temperature sensing body 52 from directly contacting the heat conducting column 21 with a higher temperature, thereby ensuring the service life of the temperature sensing body 52.

[0044] It should be noted that the heat conducting plate 53 and the heat conducting column 21 can be connected by screws.

[0045] Since the closer to the heating tube 4, the higher the temperature, the heat conducting plate 53 extends toward the side of the heat conducting column 21 away from the heating tube 4, so that the temperature sensing body 52 is away from the heating tube 4. With this design, the temperature sensing body 52 is further away from the heating tube 4, further reducing the interference of the heating tube 4 on the temperature sensing of the jump type thermostat 5.

[0046] In order to prevent the knob 6 from moving, specifically, the active gear 7 includes a gear shaft 71 and a gear part 72, the gear shaft 71 is fixedly connected to the gear part 72 and is located at the top side of the gear part 72, the knob 6 is fixedly connected to the gear shaft 71, and the base 1 is provided with a first limiting rib 15 corresponding to the top of the gear part 72 and a pressing sheet 16 corresponding to the bottom of the gear part 72, and the pressing sheet 16 presses the gear part 72 against the first limiting rib 15 to limit the axial movement of the gear part 72. With such a design, the pressing sheet 16 presses the gear part 72 against the first limiting rib 15 to limit the axial movement of the gear part 72, thereby preventing the knob 6 fixedly connected to the gear shaft 71 from moving, which is conducive to reducing the gap between the knob 6 and the base 1, and the overall appearance is more beautiful.

[0047] The first limiting rib 15 is provided with a through hole 151 for the gear shaft 71 to pass through, and the first limiting rib 15 is arranged around the gear shaft 71. Such a design satisfies the installation of the gear shaft 71, and the first limiting rib 15 is arranged around the gear shaft 71, which forms a better limiting effect on the gear part 72 and effectively prevents the gear part 72 from tilting.

[0048] And, in order to further make it safer to use, a heat-insulating gap 91 is provided between the knob 6 and the outer surface of the base 1, and the axial dimension of the heat-insulating gap 91 is D, D≤1mm. If the heat-insulating gap 91 between the knob 6 and the base 1 is greater than 1mm, the gap between the knob 6 and the base 1 is larger, affecting the aesthetics. Preferably, the heat-insulating gap 91 is 0.8mm, and the heat on the base 1 is not easily transferred to the knob 6, which effectively prevents the user from getting hot when using the knob 6, and is also conducive to ensuring that the user does not touch the base 1 when using the knob 6, making it safer to use, while making the gap between the knob 6 and the base 1 smaller, and the overall appearance more beautiful. It is understandable that the heat-insulating gap 91 can also be a suitable size such as 0.7mm, 0.9mm, 1mm, etc.

[0049] When adjusting the preset temperature of the snap-action thermostat 5, the control shaft 51 may need to rotate multiple times, and accordingly, the knob 6 needs to rotate multiple times, which affects the user experience. Therefore, the diameter of the active gear 7 is larger than the diameter of the driven gear 8. With this design, one active rotation can drive the driven gear 8 to rotate more than one circle, and the number of turns of the knob 6 can be reduced to adjust the snap-action thermostat 5 to the preset temperature, which is more convenient to use. In addition, the rotation of the large gear with the small gear is more labor-saving, and the use of the knob 6 is more labor-saving, further improving the user's good experience.

[0050] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
