Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a cooking device. Background Art

[0002] Existing cooking equipment often incorporates a kickback thermostat to detect the temperature at a specific point in the working area. If the temperature exceeds a specified limit, an internal switch opens, shutting off the heating device to prevent dry cooking or as a safety feature. Mechanical rotary switches are commonly used in cooking equipment to adjust the heat level. These switches control the temperature of the appliance by adjusting an adjustable thermostat. When the temperature detected by the adjustable thermostat reaches the user-set value, the switch opens to shut off the heating device, and when it falls below the set value, the switch closes to activate the heating device. Therefore, in circuit designs that utilize both a kickback thermostat and an adjustable thermostat, they are typically connected in series to provide a double safeguard. The temperature measuring points of the existing sudden jump thermostat and the adjustable thermostat are located in different positions. It is possible that the temperature of some areas inside the pot body exceeds the maximum temperature limit of the two thermostats, but since the temperature of the area measured by any thermostat has not reached its temperature limit, both thermostats should be disconnected, but only one of them is disconnected. At this time, if water ingress or other factors cause a short circuit in the circuit, the part of the circuit where the thermostat is not disconnected may form a loop, causing a circuit safety accident.

Simultaneously, the provision of a first temperature transfer unit and a second temperature transfer unit ensures smooth heat transfer from the pot body to both thermostats. When the temperature of the working area exceeds their maximum temperature limits, both thermostats are ensured to disconnect, thus avoiding circuit safety issues that could occur if one of the two thermostats fails to disconnect when it should.

[0033] See Figures 1 to 2 , Figure 2 A cooking device is shown, comprising a base 1 and a pot body 6 arranged on the base 1, wherein the base 1 comprises a bottom shell 101 and an upper cover 102 located above the bottom shell 101, and further comprises a sudden jump thermostat 2 and an adjustable thermostat 4. Figure 1 The sudden jump thermostat 2 and the adjustable thermostat 4 are both connected to a metal bracket 3. Figure 5 , the metal bracket 3 is installed in the base 1 and abuts against the pot body 6. In existing cooking equipment, the sudden jump thermostat 2 is a thermostat device for safety considerations. When the temperature in the working area of the cooking equipment exceeds the limit, such as when the high temperature causes the pot body 6 to dry out, the sudden jump thermostat 2 will promptly cut off the heating of the heating device. Therefore, its temperature threshold is higher than that of other thermostat devices, and it is often set at a position close to the heating area of the cooking equipment. The adjustable thermostat 4 will change its own temperature threshold according to the user's operation. Its maximum temperature threshold is lower than the temperature threshold of the sudden jump thermostat 2. When the temperature of the cooking equipment reaches the temperature threshold set by the user, the heating of the heating device is stopped. When the temperature of the cooking equipment drops below the set temperature threshold, the heating of the heating device is turned on. This cycle is repeated to achieve the goal of maintaining the temperature of the cooking equipment roughly at the temperature threshold set by the user. See Figure 2 and Figure 3The metal bracket 3 is provided with a first temperature transfer part 301 cooperating with the sudden jump thermostat 2, and a second temperature transfer part 5 cooperating with the adjustable thermostat 4. Since the metal bracket 3 is in contact with the pot body 6, the corresponding temperature transfer part can ensure that the heat of the metal bracket 3 can be smoothly transferred to the corresponding two thermostats. Firstly, it ensures the safety of the sudden jump thermostat 2, secondly, it ensures the accurate temperature adjustment of the adjustable thermostat 4, and thirdly, the temperature transfer of the two thermostats is completed by a metal bracket 3. Its structure is simple and the production cost is reduced. Fourthly, since the heat transfer paths of the two thermostats are both located on the metal bracket, the temperature signal is transmitted reliably, ensuring that the two thermostats transfer heat to the pot body 6 smoothly, so that the safety performance and temperature adjustment function are good. Especially when abnormal over-temperature occurs and the sudden jump thermostat 2 and the adjustable thermostat 4 need to be disconnected, it can ensure that both thermostats are disconnected, which greatly guarantees the circuit safety of this type of cooking equipment and improves the reliability of the cooking equipment as a whole. Figure 9 In the circuit connection of the cooking device in this embodiment, the heating device 7, the kick thermostat 2, and the adjustable thermostat 4 are connected in series. Therefore, during use, if the operating temperature of the cooking device reaches the temperature threshold of any thermostat or exceeds the maximum temperature threshold of both thermostats, one or both thermostats will be disconnected, stopping the operation of the heating device 7, thus providing a "double insurance" effect. Through this solution, the temperature measurement points of both the kick thermostat 2 and the adjustable thermostat 4 are in contact with the metal bracket 3, which in turn abuts the pot body 6. This ensures that the time interval between the kick thermostat 2 and the adjustable thermostat 4 sensing the temperature signal is very small, resulting in the kick thermostat 2 and the adjustable thermostat 4 reacting to the received temperature signal at similar times. In the prior art, because the two thermostats have different temperature measurement points or sources for receiving temperature signals, this can lead to circuit safety issues where only one thermostat is disconnected when both should be disconnected. The above solution locates the temperature sensing locations of both the snap thermostat 2 and the adjustable thermostat 4 on the metal bracket 3, ensuring that both thermostats receive the same temperature signal, resolving this circuit safety issue, improving the safety of the cooking device, and extending its service life. Preferably, the snap thermostat 2 is mounted on the metal bracket 3, thereby eliminating the need for a mounting structure for the snap thermostat 2 and reducing production costs.

[0034] Continue to see Figure 1 and Figure 2In one embodiment, the metal bracket 3 can be installed in a floating manner in the base 1. Due to the better thermal conductivity of the metal material of the metal bracket 3, the working temperature of the cooking device can be detected more sensitively. Therefore, the adjustable thermostat 4 is connected to the metal bracket 3, and the floatingly installed metal bracket 3 is in contact with the pot body 6 to ensure the contact between the metal bracket 3 and the pot body 6. Compared with the adjustable thermostat in the prior art that uses air heat conduction or contact heat conduction of plastic parts, the connection with the metal bracket 3 greatly improves its thermal conductivity.

[0035] See also Figure 5 The first temperature transfer part 301 transfers heat downward from the pot body 6 to the sudden jump thermostat 2. Therefore, in this embodiment, a downward heat transfer path is formed from the bottom of the pot body 6. This heat transfer path starts from the pot body 6 and is transferred to the first temperature transfer part 301 of the metal bracket 3. Then, it is transferred from the first temperature transfer part 301 to the temperature sensing surface of the sudden jump thermostat 2. The heat transfer path is simple and short, so that the temperature signal of the pot body 6 can be quickly transferred to the sudden jump thermostat 2. As a safety device, the sooner the sudden jump thermostat 2 receives the temperature signal of the working area of the cooking equipment, the better the safety performance of the cooking equipment will be. In addition, this heat transfer path allows the sudden jump thermostat 2 to be located below the metal bracket 3 and isolated from the outside world, thereby protecting the sudden jump thermostat 2 and preventing users from electric shock. Figure 3After the heat of the pot body 6 is transferred from top to bottom to the first temperature transfer part 301, the heat is then transferred horizontally from the first temperature transfer part 301 to the second temperature transfer part 5. The second temperature transfer part 5 then transfers the heat to the adjustable temperature controller 4, thereby transmitting the temperature signal of the pot body 6 to the adjustable temperature controller 4. The adjustable temperature controller 4 is then controlled according to the temperature threshold input by the user, thereby enabling the user to control the size of the temperature value set by the user. The heat is first transferred from top to bottom and then from inside to outside. The heat transfer path is simple and the heat transfer effect is reliable. According to the size of the metal bracket 3, the moment when the temperature signal or heat is transferred to the two thermostats is controlled. When the size of the second temperature transfer part 5 is within a certain range, the time gap between the two thermostats in obtaining the temperature signal can be ignored, thereby enabling the two thermostats to obtain the temperature signal and make judgments at the same time or approximately at the same time, and the function of the thermostat is further improved. Therefore, as a safety device, the sudden jump thermostat 2 will determine the temperature signal slightly faster than the adjustable thermostat 4. When the temperature of the pot body 6 exceeds the temperature limit of the sudden jump thermostat 2, the sudden jump thermostat 2 will first shut down the heating device 7. The temperature signal is then transmitted to the adjustable thermostat 4 via the first temperature transfer section 301 and the second temperature transfer section 5. The adjustable thermostat 4 will then shut down due to excessive temperature. Both thermostats make judgments on the same temperature signal and ensure that they are disconnected when necessary, thus solving the existing circuit safety problem. When the temperature of the pot body 6 is normal, the sudden jump thermostat 2 will conduct normally, while the adjustable thermostat 4 will make further control based on the temperature signal. It is understood that the heat is transferred horizontally from the first temperature transfer section 301 and then transferred horizontally outward from the first temperature transfer section 301, as long as it is not transferred entirely vertically downward.

[0036] See also Figure 2A hole 1021 is formed on the upper cover 102 corresponding to the metal bracket 3, and the metal bracket 3 abuts against the pot body 6 through the hole 1021. The metal bracket 3 abuts against the pot body 6 through the hole 1021, so its installation position can be located inside the base 1, protecting the metal bracket 3 and ensuring contact between the pot body 6 and the metal bracket 3. In one embodiment, the metal bracket 3 has a first heat transfer portion 301 that extends upward and passes through the hole 1021. When the pot body 6 is placed on the base 1, the pot body 6 abuts against the first heat transfer portion 301, and then the first heat transfer portion 301 is pressed downward. Since the metal bracket 3 is installed in a floating manner, the metal bracket 3 moves downward as a whole. After being installed in place, the first heat transfer portion 301 abuts against the pot body 6. It can be understood that whether the metal bracket 3 protrudes from the upper surface of the upper cover 102 or the pot body 6 extends below the hole 1021, as long as the metal bracket 3 abuts against the pot body 6, there is no limitation here. The sudden jump thermostat 2 is installed below the first temperature transfer part 301. The temperature-sensing surface of the sudden jump thermostat 2 is in contact with the inner surface of the first temperature transfer part 301, ensuring that the heat transferred from the first temperature transfer part 301 can be transferred to the sudden jump thermostat 2 and the adjustable thermostat 4 more quickly and timely, thus improving the situation where there is a long delay in the temperature measurement of the two thermostats and ensuring the safety performance of the cooking equipment. Figure 3 , the adjustable thermostat 4 cooperates with the second temperature transfer part 5, and its connection position is located below the upper cover 102, so the adjustable thermostat 4 is also located below the upper cover 102, then the sudden jump thermostat 2 and the adjustable thermostat 4 are both located in the base 1, and are protected by the base 1 to prevent external liquids or impacts from affecting the normal operation of the thermostat, ensuring the smooth operation of the cooking device. The setting of the second temperature transfer part 5 can reduce the space occupied by the adjustable thermostat 4 on the metal bracket 3, so that it can be better installed in the base 1. The stable connection of the metal bracket 3 can ensure the temperature detection of the sudden jump thermostat 2 and the adjustable thermostat 4 is stable, making the operation of the cooking device more reliable. In summary, the floating installation ensures the contact between the metal bracket 3 and the pot body 6, and the adjustable thermostat 4 can better receive the temperature signal from the working area of the cooking device, making the transmission of the temperature signal more stable and accurate, improving the temperature adjustment accuracy of the adjustable thermostat, enhancing the user's temperature adjustment experience, further ensuring the user's temperature control of the cooked food, and improving the deliciousness of the food. The sudden jump thermostat 2 and the adjustable thermostat 4 are both connected to the metal bracket 3, which provides double insurance protection for the cooking equipment. In addition, one metal bracket 3 can ensure the temperature sensing of two temperature control devices. Its structure is simple, easy to maintain, and reduces the cost of the cooking equipment.

[0037] The second heat transfer part 5 and the main body of the metal bracket 3 can be made in one piece or in separate pieces, as long as the adjustable thermostat 4 can be stably connected to the metal bracket 3. The metal properties of the second heat transfer part 5 ensure that the adjustable thermostat 4 receives the heat or temperature signal from the pot body 6 more accurately. In this way, the temperature sensed by the adjustable thermostat 4 will be closer to the operating temperature of the cooking device, allowing the adjustable thermostat 4 to respond promptly to the feedback of the temperature signal and control the start and stop of the heating device, thereby improving the accuracy of temperature sensing and the timeliness of feedback, and further improving the temperature adjustment accuracy of the adjustable thermostat 4. Figure 9 In this embodiment, the sudden jump thermostat 2 is directly connected to the adjustable thermostat 4, that is, there is only a wire between the sudden jump thermostat 2 and the adjustable thermostat 4. The advantage of direct connection is that since the sudden jump thermostat 2 and the adjustable thermostat 4 are both connected to the metal bracket 3, the two are located close to each other, so the direct connection makes the circuit connection simpler and more convenient, and it is not easy to install it incorrectly during the production process, which further guarantees the safety of the circuit. In addition, during the operation of the cooking device, the two thermostats are close and connected in series, which makes temperature feedback and processing more timely. In addition, when abnormal conditions occur, such as dry burning, the two thermostats can be disconnected at the same time or approximately at the same time, which is safer.

[0038] See Figure 7 A sealing rubber ring 1025 is provided in the hole 1021. The first heat transfer portion 301 and the sealing rubber ring 1025 have an interference fit, filling the gap between the first heat transfer portion 301 and the inner wall of the hole 1021. Therefore, the sealing rubber ring 1025 prevents liquid from entering the base 1 through the hole 1021 of the upper cover 102, ensuring the safety of the cooking device and the normal operation of the knob switch. The interference fit between the first heat transfer portion 301 and the sealing rubber ring 1025 provides a better sealing effect.

[0039] See Figure 4 The second temperature transfer portion 5 has a bend 501. Since the metal bracket 3 abuts the pot body 6, there is a possibility that liquid may flow into the interior of the base 1. The liquid may flow along the metal bracket 3 to the adjustable thermostat 4, causing a short circuit in the adjustable thermostat 4 and affecting the normal operation of the cooking device. The provision of the bend 501 solves the above problem. Even if liquid enters, the liquid first flows from the surface of the metal bracket 3. When passing through the second temperature transfer portion 5, the liquid drips from the bend of the bend 501, preventing the liquid from contacting the adjustable thermostat 4, ensuring the normal operation of the adjustable thermostat 4, and ensuring the user's reliable function of adjusting the temperature through the adjustable thermostat.

[0040] See Figure 5In one embodiment, the sudden jump thermostat 2 is located below the first temperature transfer portion 301, so that the temperature-sensing surface of the sudden jump thermostat 2 is close to the first temperature transfer portion 301, forming a more direct temperature transfer path and improving the heat transfer effect. The lower end surface of the pot body 6 has a raised portion 601 corresponding to the first temperature transfer portion 301, and the raised portion 601 abuts the first temperature transfer portion 301. The advantage of the above solution is that the extension of the raised portion 601 can make this part better contact with the first temperature transfer portion 301, and the raised portion 601 plays a foolproof role, which will prop up the pot body 6 when the user does not put it in place, or can provide support when the user places the pot body 6 alone on a flat surface. When the cooking device is in working state, the pot body 6 is placed on the base 1, and the heat of the pot body 6 is transferred to the first temperature transfer part 301 through the contact between the protrusion 601 and the first temperature transfer part 301, so that the sudden jump thermostat 2 located below the first temperature transfer part 301 and the adjustable thermostat 4 connected to the metal bracket 3 detect the working temperature of the pot body and transmit the temperature signal.

[0041] See also Figure 5 The metal bracket 3 is floatingly connected to the lower surface of the upper cover 102, so that when the pot body 6 is placed on the base 1, the user can feel the contact between the raised portion 601 of the pot body 6 and the first heat transfer portion 301. As the pot body 6 is lowered, the raised portion 601 can push the floatingly connected metal bracket 3 downward. When the contact surface of the first heat transfer portion 301 or the raised portion 601 deforms, a gap will be generated between the two, and the heat conduction effect will be reduced. Since the present application provides a floatingly connected metal bracket 3, the elastic force is used to squeeze the first heat transfer portion 301 closer to the raised portion 601, thereby eliminating the gap to a certain extent, ensuring the heat transfer effect between the first heat transfer portion 301 and the raised portion 601, and ensuring the accuracy of the temperature detected by the adjustable thermostat 4 on the metal bracket 3. When the pot body 6 is placed in place, the first heat transfer portion 301 is pushed downward to a certain position, and the raised portion 601 is pressed and abutted against the first heat transfer portion 301, resulting in a closer abutment and better heat transfer effect. Hole 1021 acts as a horizontal limiter for raised portion 601, ensuring a more stable placement of pot 6 on base 1 and preventing it from shaking, providing a positive user experience. Proper placement further ensures heat transfer from pot 6, ensuring accurate temperature detection by each thermostat. During placement, the user can feel the pot 6 being inserted into base 1, providing a comfortable placement experience and enhancing the user experience. In other embodiments, metal bracket 3 can also be floatingly connected to bottom case 101. This is a conventional alternative in the art and will not be discussed further here.

The cam 1024 is a screw threaded hole in the bottom of the metal support 3 In other embodiments, the lower surface of the upper cover 102 has at least one connecting column 1022, and the metal bracket 3 is mounted on the connecting column 1022. The metal bracket 3 is limited to the connecting column 1022 by a gasket 1023 and a screw. The connecting column is also mounted with an elastic member 1024, such as a spring or other elastic component, which can realize the installation of the metal bracket 3, and there is no restriction here.

[0043] See also Figures 2 to 3The adjustable thermostat 4 has a knob portion 401, a connecting rod 402 and a thermostat body 403. The thermostat body 403 receives heat or temperature signals from the pot body 6 through the second temperature transfer portion 5. The knob portion 401 is located on the outer wall 1011 of the bottom shell. The knob portion 401 is rotatably connected to the thermostat body 403 through the connecting rod 402. When the temperature of the thermostat body 403 reaches the temperature threshold, the heating device of the cooking device is disconnected to control the start and stop of the heating device. Therefore, the connection between the thermostat body 403 and the metal bracket 3 makes its own temperature change closer to the temperature change of the working area of the cooking device, so that the temperature response of the adjustable thermostat 4 can be more accurate, thereby improving its temperature adjustment accuracy. In the prior art, because the thermostat body 403 is directly connected to the knob portion 401, the thermostat body 403 is located near the knob portion 401, such as on the inner sidewall of the bottom housing 101. However, the sidewall of the bottom housing 101 is typically far from the working area of the cooking device, and the bottom housing 101 is often made of plastic with poor thermal conductivity. As a result, the temperature sensing area of the thermostat body 403 is poor, resulting in poor temperature sensing and affecting the user's ability to adjust the operating temperature of the cooking device. In this embodiment, the position of the thermostat body 403 is changed by connecting the connecting rod 402, and the knob portion 401 is rotatably connected to the thermostat body 403 via the connecting rod 402. This allows the thermostat body 403 to be closer to the working area of the cooking device, thereby better sensing the real-time operating temperature of the cooking device and achieving more accurate temperature adjustment, improving the performance of the cooking device and enhancing the user experience. Specifically, the user rotates the knob portion 401, and the knob portion 401 drives the connecting rod 402 to rotate to change the relevant parameters of the trigger device of the thermostat body 403, such as the position of the trigger device. When the knob portion 401 is at an angle for closing the device, the trigger device disconnects the thermostat body 403 from the heating device; and when the knob portion 401 is at an angle for opening the device, if the temperature of the thermostat body 403 does not reach the temperature threshold, the thermostat body 403 remains connected to the heating device. If the temperature of the thermostat body 403 reaches the temperature threshold, the thermostat body 403 triggers the trigger device to disconnect it from the heating device; when the knob portion 401 is at different angles for opening the device, the temperature threshold of the thermostat body 403 is different, so that the user can adjust the working temperature of the cooking device through the knob portion 401 of the adjustable thermostat 4, realizing a knob switch with accurate temperature adjustment. The trigger device can be a mechanical structure such as a pin fit. The trigger device is a prior art and is not limited here as long as it can achieve the aforementioned triggering method.

[0044] See Figure 1There are two adjustable thermostats 4, and correspondingly, there are two sudden jump thermostats 2 and metal brackets 3. The adjustable thermostats 4 match the heating device of the cooking device, that is, there are two heating devices. It can be understood that in this embodiment, the adjustable thermostats 4 are set according to the heating devices so that each heating device has a corresponding adjustable thermostat 4 for adjustment, and each metal bracket 3 is connected to at least one sudden jump thermostat 2 and one adjustable thermostat 4 to form a set of independent heating solutions. Figure 9 There are two circuits in which the heating device 7, the sudden jump thermostat 2 and the adjustable thermostat 4 are connected in series. The two identical series circuits are connected in parallel to achieve temperature control of the two heating devices 7 and protection of the two heating areas. In addition, there are two fuses 8 at one end of the overall circuit. When the circuit temperature exceeds the limit, the fuse 8 will disconnect to cut off the circuit, further ensuring the circuit safety of the cooking equipment, forming a safe and reliable cooking equipment control circuit with dual drive + adjustable temperature control + dual fuses + dual sudden jump thermostat. It can be known that the number of heating devices 7 and their corresponding circuits can be increased as needed, and there is no restriction here. In addition, each heating device 7 can also correspond to a cooking cavity to achieve zoned cooking and improve the function of the cooking equipment and user experience.

[0045] See Figure 2 and Figure 8 The cooking device also includes a pot body 6, a heating device 7 mounted on the lower end surface of the pot body 6, and an electrical connector 103 provided on the base 1. When the cooking device is in operation, the pot body 6 is placed on the base 1, and the heating device 7 is electrically connected to the electrical connector 103, thereby realizing a split-coupled cooking device. This makes it easier to clean the pot body 6 after use. The adjustable thermostat 4 is connected to the electrical connector 103 through a circuit design, and then to the heating device 7, thereby controlling the on and off of the heating device 7. The pot body 6 also includes a separating rib 602, which divides the cavity of the pot body 6 into two cavities. Each cavity has a corresponding heating device 7. This allows each adjustable thermostat 4 to adjust the heating device 7 below it in response to a cavity, thereby realizing zoned heating control. For the cooking device, heating control can be achieved in different areas, which is more powerful and has more diverse application scenarios. In other embodiments, the number and structure of the dividing ribs 602 can be different to divide the pot body 6 cavity into more cavities, and each cavity corresponds to a separate heating device 7, and each heating device 7 corresponds to an adjustable thermostat 4 that controls its start and stop, thereby achieving independent heating control in more areas. The pot body 6 also has a pot lid 603, which is placed above the pot body 6 cavity. When food needs to be taken out or put in, the pot lid 603 is removed to open the cavity. When rapid heating is required, the pot lid 603 is placed to allow heat to accumulate faster in the pot body 6 cavity, causing the temperature to rise faster.

[0046] In the embodiment adopting any of the above solutions, the cooking device may be an electric hot pot, an electric steamer, an electric rice cooker or an air fryer, which are kitchen appliances that often use adjustable thermostats and sudden temperature controllers. Figure 2 As shown, the cooking device is an electric hot pot, achieving a zoned hot pot with high circuit safety and accurate temperature control. By adopting any of the above-mentioned embodiments, the sudden trip thermostat 2 and the adjustable thermostat 4 can receive temperature signals synchronously or approximately synchronously. In the event of an abnormal overtemperature, both thermostats must be disconnected, ensuring circuit safety. It is understood that the cooking device can also be other types of cooking devices that can utilize the sudden trip thermostat and adjustable thermostat connected to the same metal bracket, without limitation.
