[0024] Example 1
[0025] Combined with Figure 1-4 This embodiment provides a heating plate device, including a heating plate 100, a heat-conducting aluminum plate 104, a plurality of fixing brackets 105, a plurality of thermostats 103, a first heating tube 101 and a second heating tube 102. The heating plate 100 is fixed to one side of the heat-conducting aluminum plate 104, the first heating tube 101 and the second heating tube 102 are fixed to the other side of the heat-conducting aluminum plate 104, the fixing bracket 105 is fixedly connected to both the first heating tube 101 and the second heating tube 102, and each thermostat 103 is supported by each fixing bracket 105 and is fixedly connected to each fixing bracket 105.
[0026] Both the first heating tube 101 and the second heating tube 102 are provided with openings. The first heating tube 101 and the second heating tube 102 are concentrically arranged. The first heating tube 101 is located outside the second heating tube 102. The opening of the first heating tube 101 extends in the direction of the second heating tube 102, and the corresponding extension area is provided with the solid part of the second heating tube 102. The opening of the second heating tube 102 extends in the direction of the first heating tube 101, and the corresponding extension area is provided with the solid part of the first heating tube 101.
[0027] The first heating tube 101 and the second heating tube 102 constitute a first sector area 11 and a second sector area 12, which are distributed on both sides of the opening of the first heating tube 101. At the same time, the first sector area 11 and the second sector area 12 are also distributed on both sides of the opening of the second heating tube 102, and the two sectors and the heating tube are concentrically arranged. Each fixing bracket 105 is distributed in the first sector area 11 and the second sector area 12.
[0028] The thermostat 103 located in the first sector area 11 is defined as the first thermostat, and the thermostat 103 located in the second sector area 12 is defined as the second thermostat. The first sector area 11 and the second sector area 12 are divided into a number of installation areas of equal area along the radial extension direction of the first heating tube 101. The installation area divided by the first sector area 11 is defined as the first installation area, and the installation area divided by the second sector area 12 is defined as the second installation area. The number of first installation areas is greater than or equal to the number of first thermostats, and the first thermostats are distributed at the center of the first installation area; the number of second installation areas is greater than or equal to the number of second thermostats, and the second thermostats are distributed at the center of the second installation area.
[0029] A heating plate device of the present embodiment can make the heating plate 100 heated more evenly, improve the heating efficiency, and by directly setting the temperature controller 103 on the first heating tube 101 and the second heating tube 102, and evenly distributing it in the common heating area of the first heating tube 101 and the second heating tube 102, the uniformity of temperature sensing and the response speed of the temperature controller 103 are improved.
[0030] In a heating plate device of this embodiment, the first heating tube 101 and the second heating tube 102 are used to heat the heat-conducting aluminum plate 104 and the heating plate 100, and the temperature controller 103 is used to detect the temperature and perform over-temperature protection.
[0031] The first heating tube 101 and the second heating tube 102 constitute a first sector area 11 and a second sector area 12. The first sector area 11 and the second sector area 12 are the common heating areas of the first heating tube 101 and the second heating tube 102. The first sector area 11 and the second sector area 12 are distributed on both sides of the opening of the first heating tube 101, and are also distributed on both sides of the opening of the second heating tube 102.
[0032] Please refer to the attached Figure 1 or attached Figure 2 In the embodiment, the opening positions of the first heating tube 101 and the second heating tube 102 are used to connect the power supply, that is, the ends of the first heating tube 101 and the second heating tube 102 close to the opening are the connection ends, and the connection ends include the insulating layer 201 and the terminal 202. For example, in one embodiment, the starting point of the first sector area 11 is the end of the insulating layer 201 at one end of the first heating tube 101, which is offset by 15mm-25mm in the direction away from the terminal 202 of the first heating tube 101. The terminal point of the first sector area 11 is the end of the insulating layer 201 at one end of the second heating tube 102, which is offset by 15mm-25mm in the direction away from the terminal 202 of the second heating tube 102. Similarly, the starting point of the second sector area 13 is the end of the insulating layer 201 at the other end of the first heating tube 101, which is offset by 15mm-25mm in the direction away from the terminal 202 of the first heating tube 101. The terminal end of the second sector area 12 is where the end of the insulating layer 201 at the other end of the second heating tube 102 is offset by 15 mm to 25 mm in a direction away from the connection terminal 202 of the second heating tube 102. In this embodiment, the offset distance at each location is preferably 20 mm.
[0033] The first sector area 11 and the second sector area 12 have a relatively large heat generation, so the excess heat can be dispersed outside the range of the first sector area 11 and the second sector area 12, such as the remaining areas of the first heating tube 101 and the second heating tube 102, thereby better alleviating the problem of excessive temperature in the local heating area, and reducing the temperature difference in the heating area on the surface of the heating disk 100, thereby effectively improving the uniformity of the heating temperature of the heating disk 100 and reducing the risk of cracking of the heating disk 100.
[0034] In this embodiment, the layout of the thermostats 103 is to ensure that the heating area of each thermostat 103 is consistent. In this form, the heat received by each thermostat 103 is roughly equal, thereby reducing the temperature sensing deviation between different thermostats 103, so that each thermostat 103 can capture the temperature more sensitively and effectively, and play a more effective protective role.
[0035] Specifically, the layout of the thermostat 103 is as follows: the thermostat 103 located in the first sector area 11 is defined as the first thermostat, and the thermostat 103 located in the second sector area 12 is defined as the second thermostat. One or more first installation areas are divided in the first sector area 11, and one or more second installation areas are also divided in the second sector area 12. The areas of the first installation area and the second installation area are equal. In this case, the heating areas of the thermostats 103 located at the centers of the respective installation areas are also roughly equal.
[0036] Furthermore, the number of installation areas can be the same as the number of thermostats 103, and the number of installation areas can also be greater than the number of thermostats 103. Since the first sector area 11 and the second sector area 12 are always heated by the first heating tube 101 and the second heating tube 102, the heating areas of the thermostats 103 located in any installation area are roughly equal, and the amount of heat received is also equal under normal circumstances, thereby ensuring the uniformity of temperature sensing of each thermostat 103. When the local temperature is abnormal, since there are multiple thermostats 103, the abnormality at any position can be responded to by the nearby thermostats 103, thereby greatly improving the overall temperature sensitivity.
[0037] It should be noted that, in the present embodiment, the heating areas of the thermostats 103 are approximately equal, which means that in actual engineering, the heating areas of the thermostats 103 are kept within an allowable range. Within this range, the numerical difference in the specific heating areas will not lead to significant differences in the heating conditions of different thermostats 103, and the differences in the heating conditions of different thermostats 103 are within the allowable range.
[0038] In a preferred embodiment, the thermostat 103 is a snap-action thermostat 103, and the thermostat 103 can be fixed to the surface of the fixing bracket 105 by screws. The fixing bracket 105 is preferably a four-legged claw, and the front and rear four claws are respectively fixed to the first heating tube 101 and the second heating tube 102 by extrusion or brazing.
[0039] Example 2
[0040] Combined with Figure 4 Compared with the technical solution of Example 1, a heating plate device of this embodiment can be improved as follows: a notch is provided on the heat-conducting aluminum plate 104, and the opening of the first heating tube 101 is matched with the notch.
[0041] In this embodiment, a notch is provided on one side of the thermal conductive aluminum plate 104, and the notch may be fan-shaped, corresponding to the opening of the first heating tube 101. Compared with a thermal conductive aluminum plate 104 without a notch, the thermal conductive aluminum plate 104 is more likely to have loose contact with the surface of the heating plate 100 and there is a risk of cracking. The setting of the notch in this embodiment can avoid the problem of poor contact caused by the thermal conductive aluminum plate 104 warping during the brazing process.
[0042] It is conceivable that when a thermally conductive aluminum plate 104 with a notch is used, in order to compensate for the uneven structure of the thermally conductive aluminum plate 104, the first heating tube 101 and the second heating tube 102 can be rotated to align the opening position of the thermally conductive aluminum plate 104, and the relative angle between the first heating tube 101 and the second heating tube 102 can be adjusted to change the areas of the first sector area 11 and the second sector area 12, thereby improving the uniformity of the heating temperature of the heating plate 100 and further reducing the risk of cracking of the heating plate 100.
[0043] Example 3
[0044] Combined with Figure 1-4 Compared with the technical solutions of Embodiment 1 or 2, the heating plate device of this embodiment can be improved as follows: the area ratio of the first sector area 11 to the second sector area 12 is 1.5 to 2.3.
[0045] According to the length and shape of the heating tubes in current cooking equipment such as steam ovens, this embodiment sets the area ratio of the first sector area 11 and the second sector area 12 to be within the range of 1.5 to 2.3. In a preferred setting, the area ratio can be 2. Therefore, when three or multiple thermostats 103 are arranged, the heating area of the first thermostat in the first installation area divided by the first sector area 11 is roughly equal to the heating area of the second thermostat in the second installation area divided by the second sector area 12, so that the heat received by each thermostat 103 is roughly equal, thereby reducing the temperature sensing deviation between different thermostats 103, so that each thermostat 103 can capture the temperature more sensitively and effectively, and play a more effective protective role.
[0046] Example 4
[0047] Combined with Figure 1-4 A heating plate device of this embodiment can be improved as follows compared with any of the technical solutions in embodiments 1-3: the center line of the opening of the first heating tube 101 and the center line of the opening of the second heating tube 102 form an angle a, and the angle a is 130° to 170°.
[0048] According to the length and shape of the heating tubes in current cooking equipment such as steam ovens, in this embodiment, the angle a between the center lines of the openings of the first heating tube 101 and the second heating tube 102 is selected within the range of 130° to 170°, preferably 150°. In this case, when at least three thermostats 103 are arranged, the heating areas of the thermostats 103 can be kept consistent, so that the heat received by the thermostats 103 is roughly equal, thereby reducing the temperature sensing deviation between different thermostats 103, so that each thermostat 103 can capture the temperature more sensitively and effectively, and play a more effective protective role.
[0049] At the same time, in the case of this embodiment, the total area of the first sector zone 11 and the second sector zone 12 is within a smaller range. Relatively speaking, the total area of the remaining parts of the first heating tube 101 and the second heating tube 102 is enlarged, and the excess heat can be dispersed to the area outside the first sector zone 11 and the second sector zone 12, so as to better alleviate the problem of excessive temperature in the local heating area, reduce the temperature difference in the heating area on the surface of the heating plate 100, thereby effectively improving the uniformity of the heating temperature of the heating plate 100 and reducing the risk of cracking of the heating plate 100.

In a conceivable implementation, the heat-conducting aluminum plate 104 is also designed with a corresponding concave-convex structure to adapt to the structure of the heating plate 100 to ensure that the heating plate 100 and the heat-conducting aluminum plate 104 are tightly connected.

[0055] In this embodiment, the cross-sections of the first heating tube 101 and the second heating tube 102 are trapezoidal, and the wider bottom surfaces of the first heating tube 101 and the second heating tube 102 are in contact with the heat-conducting aluminum plate 104 to achieve a better heat transfer effect. In a conceivable embodiment, the wider bottom surfaces of the first heating tube 101 and the second heating tube 102 are connected and fixed to the heat-conducting aluminum plate 104 by brazing.

[0058] In this embodiment, by using the positioning hole 108 in conjunction with the positioning welding piece, the relative position of the heating plate 100 and the thermally conductive aluminum plate 104 can be fixed during the welding process, thereby better completing the welding between the heating plate 100 and the thermally conductive aluminum plate 104 and improving the welding effect.

In a conceivable embodiment, the thin film sensor is fixedly connected to the heat-conducting aluminum plate 104 by a positioning screw.
