Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a pot support and a gas stove. Background Art

[0002] Gas stoves are popular and widely used in our daily lives due to their convenience and ease of use. However, gas safety is also receiving increasing attention. During use, gas stoves often burn empty due to users being busy or forgetting to turn off the stove. This not only wastes gas but can also easily cause fires. Some existing gas stoves include a fire extinguisher and a temperature sensor for detecting the temperature of the pot bottom. When the temperature sensor detects that the pot bottom temperature exceeds a preset value, the fire extinguisher sprays a fire extinguishing agent onto the stove burner, extinguishing the flames.

[0003] However, although such a gas stove can avoid dry burning or fire, the fire extinguishing agent sprayed onto the burner can easily cause the burner to be blocked, and it will bring the burden of cleaning the burner to the user, which is not conducive to improving the user experience. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the gas stove in the prior art that the fire extinguishing agent easily causes the burner to be blocked when the fire is automatically extinguished, and the user needs to clean the burner, thereby providing a pot holder and gas stove that can avoid dry burning and is not prone to burner blockage.

[0005] In order to solve the above problems, the first aspect of the present invention provides a pot bracket, comprising: a bracket body, on which an air vent is formed; a door body, which is movably arranged on the bracket body, and the door body has a first state of blocking the air vent and a second state of opening the air vent; a driving mechanism, which is connected to the door body; and a control module, which is communicatively connected to the driving mechanism.

[0006] Furthermore, the control module is a thermostat, which can control the driving mechanism to switch the door body to the first state when the temperature of the bottom of the pot reaches a preset temperature.

[0007] Furthermore, a temperature sensor is provided on the bracket body, which is suitable for detecting the temperature of the bottom of the pot. The control module is communicated with the temperature sensor. The control module can control the driving mechanism to switch the door body to the first state when the temperature of the bottom of the pot reaches a preset temperature.

[0008] Furthermore, the pot support also includes a slide rail, which is slidably connected to the side wall of the support body. The door body is arranged between the slide rail and the support body and is fixedly connected to the slide rail. The slide rail is connected to the driving mechanism.

[0009] Furthermore, the slide rail extends along the circumference of the bracket body.

[0010] Furthermore, a rack is formed on one side of the slide rail away from the bracket body. The driving mechanism is a rotation source. A gear is sleeved on the output shaft of the rotation source, and the gear is meshed with the rack.

[0011] Furthermore, a fixing buckle is formed on the slide rail, and the door body is engaged with the fixing buckle.

[0012] Furthermore, an elastic member is provided on the top of the bracket body, and the temperature sensor is provided on the elastic member.

[0013] Further, the control module includes a temperature setter, the temperature setter is capable of setting a preset temperature, and / or the temperature setter has a temperature display screen.

[0014] Furthermore, the pot support also includes a timer, and the control module is communicatively connected to the timer, and can control the driving mechanism to drive the door to block the air vent when the timing time of the timer reaches a preset time.

[0015] A second aspect of the present invention relates to a gas stove, comprising a burner and a pot support surrounding the burner, wherein the pot support is the pot support provided by the first aspect of the present invention.

[0016] Furthermore, the gas stove further includes a gas pipeline and a thermoelectric protection device, wherein the gas pipeline is suitable for connecting the burner with the gas source, and the thermoelectric protection device includes:

[0017] A solenoid valve is provided in the gas pipeline and is suitable for controlling the on and off of the gas pipeline;

[0018] A thermocouple is disposed in the furnace head and is communicatively connected with the solenoid valve.

[0019] The present invention has the following advantages:

[0020] 1. It can be seen from the above technical solution that the pot support of the first aspect of the present invention mainly includes a support body, a door body, a drive mechanism and a control module. Therefore, during normal cooking, the air vents on the support body can allow air to enter and assist the flame on the gas stove, so that the cooking operation can proceed normally. When the user is busy or forgets to turn off the fire, resulting in dry burning or cooking time being too long, the control module can control the drive mechanism to switch the door body to the first state of blocking the air vents, thereby isolating the inside of the pot support from the air and causing the flame to go out. Therefore, the pot support of the present invention can avoid the occurrence of dry burning or cooking time being too long, and will not cause the risk of burner blockage, and will not bring the extra burden of cleaning the burner and pot support to the user. In addition, the pot support of the present invention has a simple structure, is easy to manufacture, is safe and reliable to use, and is easy to implement and promote.

[0021] 2. The control module is a thermostat, which can automatically control the drive mechanism to switch the door to the first state when the temperature of the pot bottom exceeds the set value. It has the advantages of low cost and simple structure.

[0022] 3. A temperature sensor is provided on the bracket body. The temperature sensor is adapted to detect the temperature of the pot bottom. The control module is in communication with the temperature sensor. When the temperature sensor detects that the temperature of the pot bottom is greater than a preset temperature, the control module controls the drive mechanism to switch the door to the first state. The user can then adjust the preset temperature to meet the user's cooking requirements for different foods. When the temperature sensor detects that the temperature of the pot bottom has dropped to a safe level, the door switches to the first state, allowing cooking to continue.

[0023] 4. The door body is slidably connected to the bracket body. The pot bracket also includes a slide rail. The slide rail is slidably connected to the side wall of the bracket body. The door body is arranged between the slide rail and the bracket body and is fixedly connected to the slide rail, and the slide rail is connected to the drive mechanism. The slide rail can make the sliding of the door body on the bracket body smoother, and at the same time can play a role in constraining the running trajectory of the door body. The slide rail, the door body and the drive mechanism are all arranged on the inner side of the bracket body. In order to enable the slide rail to be slidably connected to the bracket body, the bracket body is provided with a limiting groove extending along the sliding direction of the slide rail. A limiting protrusion matching the limiting groove is formed on the slide rail, or a limiting depression extending along the sliding direction of the slide rail is formed on the slide rail, and a limiting protrusion suitable for matching with the limiting groove is formed on the bracket body.

[0024] 5. The slide rail extends along the circumference of the bracket body. Since the length of the bracket body along the circumference is greater than the length in other directions, setting the slide rail to extend along the circumference of the bracket body can increase the adjustment range of the ventilation volume of the air vent. The air vent can be set larger and avoid obstruction to the flame burning on the gas stove in the cooking state.

[0025] 6. An elastic member is installed at the top of the support body, and the temperature sensor is mounted on this elastic member. When the pot bottom is placed on the support, the elastic member is compressed by the support, causing it to fit tightly against the pot bottom and the temperature sensor mounted on the elastic member to fit tightly against the pot bottom, enabling the temperature sensor to more accurately detect the pot bottom temperature. The elastic member is a metal spring.

[0026] 7. The control module includes a temperature controller. The temperature controller can set a preset temperature and has a temperature display. Users can use the temperature controller to modify the preset temperature and use the temperature display to monitor the temperature of the pot bottom. The temperature display not only allows users to easily monitor the temperature of the pot bottom in different cooking modes, enabling them to select the appropriate preset temperature for each cooking mode, but also assists users in controlling the cooking temperature.

[0027] 8. The pot holder also includes a timer. The control module communicates with the timer and controls the drive mechanism to actuate the door to seal the vent when the timer reaches a preset time. This allows users to set cooking times according to different cooking modes without having to sit in front of the stove and avoid problems such as dry cooking, thus improving the user experience.

[0028] 9. A second aspect of the present invention relates to a gas stove comprising a burner and a pot support surrounding the burner. The pot support is the pot support of the first aspect of the present invention. The gas stove of the second aspect of the present invention includes the pot support of the first aspect of the present invention, thereby achieving the beneficial effects of the pot support of the first aspect of the present invention. It can prevent dry burning, eliminate the risk of burner blockage, and avoid the additional burden of cleaning the burner and pot support for the user.

[0029] 10. The gas stove also includes a gas pipeline and a thermoelectric protection device. The gas pipeline is suitable for connecting the burner to the gas source, and the thermoelectric protection device includes a solenoid valve and a thermocouple. Among them, the solenoid valve is arranged in the gas pipeline and is suitable for controlling the on and off of the gas pipeline. The thermocouple is arranged in the burner and is connected to the solenoid valve. Current gas stoves generally use thermocouples to maintain the valve of the gas stove. The battery powers the valve for about 8 seconds, and the flame burns. After 8 seconds, the flame burns the thermocouple, and the thermocouple generates a valve current to keep the solenoid valve open. When the temperature sensor in the pot bracket detects that the temperature of the bottom of the pot is higher than the preset temperature, the control module can control the drive mechanism to switch the door body to the first state, isolate the air to extinguish the flame, the thermocouple valve current disappears, and the solenoid valve is closed, so as not to cause gas leakage.

[0038] In addition, 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.

[0039] Example 1

[0040] Figure 1 The pot support of embodiment 1 of the present invention is shown, and the door body is in the second state. Figure 2 The pot support of embodiment 1 of the present invention is shown, and the door body is in the first state. Figure 1 and Figure 2As shown, this embodiment relates to a pot support 100, comprising a support body 1, a door 3, a drive mechanism 4, and a control module. The support body 1 is formed with a ventilation opening 11. The door 3 is movably mounted on the support body 1. The door 3 has a first state in which the ventilation opening 11 is blocked, and a second state in which the ventilation opening 11 is open. The drive mechanism 4 is connected to the door 3. The control module is in communication with the drive mechanism 4 and is capable of controlling the drive mechanism 4 to switch the door 3 to the first state when the temperature of the pot bottom reaches a preset temperature. Preferably, the top of the pot support 100 is used to place pots and is able to fit tightly against the pot, so that the pot seals the top of the pot support 100. The preset temperature can be selected from a typical temperature of the pot when dry-boiling, or can be set by the user based on usage requirements. It is generally the temperature of the pot bottom when dry-boiling, for example, any value between 280-300°C. In this embodiment, the preset temperature is 290°C.

[0041] It can be seen from the above technical solution that the pot support 100 of this embodiment mainly includes a support body 1, a door body 3, a drive mechanism 4 and a control module. Therefore, during normal cooking, the air vents 11 on the support body 1 can allow air to enter and help the flame on the gas stove to burn, so that the cooking operation can proceed normally. When the user is busy or forgets to turn off the fire, resulting in dry burning or cooking time being too long, the control module can control the drive mechanism 4 to switch the door body 3 to the first state of blocking the air vents 11, thereby isolating the air inside the pot support 100 and causing the flame to go out. Therefore, the pot support 100 of this embodiment can not only avoid the occurrence of dry burning or cooking time events, but also will not cause the risk of burner blockage, and will not bring the extra burden of cleaning the burner and pot support 100 to the user. In addition, the pot support 100 of this embodiment has a simple structure, is easy to manufacture, is safe and reliable to use, and is easy to implement and promote.

[0042] In an embodiment not shown, the control module can be optionally a thermostat. When the control module is a thermostat, it can automatically control the drive mechanism 4 to switch the door body 3 to the first state when the temperature of the bottom of the pot exceeds the set value, which has the advantages of low cost and simple structure. Preferably, in this embodiment, a temperature sensor 2 is provided on the bracket body 1. The temperature sensor 2 is suitable for detecting the temperature of the bottom of the pot. The control module is communicatively connected with the temperature sensor 2. The control module can control the drive mechanism 4 to switch the door body 3 to the first state when the temperature sensor 2 detects that the temperature of the bottom of the pot is greater than the preset temperature. At this time, the user can adjust the preset temperature according to the use requirements to meet the user's cooking needs for different foods. When the temperature sensor detects that the temperature of the bottom of the pot has dropped to a safe temperature, the door body can be switched to the second state, allowing the cooking operation to continue.

[0043] The control module can be configured to automatically control the drive mechanism to switch the door body to the second state after detecting that the temperature of the bottom of the pot has dropped to a safe temperature. It can also be configured to automatically control the drive mechanism to switch the door body to the second state after receiving a first control instruction and determining that the temperature of the bottom of the pot has dropped to a safe temperature. The first control instruction refers to an instruction to open the pot support. The safety temperature can be set by the user according to usage requirements, for example, 60°C. The control module may include a programmable logic control component (such as a PLC or CPU), a memory, and electronic components connected to the programmable logic control component, etc., which are well known to those skilled in the art and will not be described in detail here.

[0044] The door body 3 may be hinged on the bracket body 1 or may be slidably connected to the bracket body 1. For example, in the present embodiment, the door body 3 is slidably connected to the bracket body 1. Preferably, the pot bracket 100 further includes a slide rail 5. The slide rail 5 is slidably connected to the side wall of the bracket body 1. The door body 3 is arranged between the slide rail 5 and the bracket body 1 and is fixedly connected to the slide rail 5, and the slide rail 5 is connected to the drive mechanism 4. The slide rail 5 can make the sliding of the door body 3 on the bracket body 1 smoother, and at the same time can play a role in constraining the running trajectory of the door body 3. The slide rail 5, the door body 3 and the drive mechanism 4 may be optionally arranged on the inner side of the bracket body 1, or may be optionally arranged on the outer side of the bracket body 1. In the example Figure 1 and Figure 2 In the illustrated embodiment, the slide rail 5, door body 3, and drive mechanism 4 are all disposed inside the support body 1. To enable the slide rail 5 to be slidably connected to the support body 1, the support body 1 is provided with a retaining groove extending in the sliding direction of the slide rail 5. Alternatively, the slide rail 5 is provided with a retaining protrusion that matches the retaining groove, or a retaining depression extending in the sliding direction of the slide rail 5 is provided, and the support body 1 is provided with a retaining protrusion that is adapted to engage with the retaining depression.

[0045] The slide rail 5 may optionally extend radially or circumferentially of the support body 1, or may be arranged obliquely on the support body 1. Preferably, in this embodiment, the slide rail 5 extends circumferentially of the support body 1. Since the length of the support body 1 in the circumferential direction is greater than that in other directions, extending the slide rail 5 circumferentially of the support body 1 can increase the adjustment range of the ventilation volume of the air vent 11, allowing the air vent 11 to be larger and avoiding obstruction to the flame burning on the gas stove during cooking.

[0046] The driving mechanism 4 is preferably, but not limited to, a linear driving mechanism 4 and a rotation source. For example, when the driving mechanism 4 is a linear driving mechanism 4, the slide rail 5 can be configured to extend in the up-down direction, and the linear driving mechanism 4 is connected to the door body 3 and drives the door body 3 to slide in the up-down direction. The linear driving device can be selected as a device capable of outputting linear motion, such as a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, or a combination of a motor and a gear 41 and a rack 51. In this embodiment, a rack 51 is formed on the side of the slide rail 5 away from the bracket body 1, the driving mechanism 4 is a rotation source, and a gear 41 is sleeved on the output shaft of the rotation source, and the gear 41 is engaged with the rack 51. The rotation source can be selected as a device capable of outputting rotation, such as a motor, an engine, a hydraulic motor, or a combination of one of them and a reducer.

[0047] The door body 3 is preferably, but not limited to, fixedly connected to the slide rail 5 by bonding, welding, riveting or bolting. For example, in this embodiment, a fixing buckle 6 is formed on the slide rail 5, and the door body 3 is snapped into the fixing buckle 6.

[0048] In this embodiment, an elastic member is provided at the top of the support body 1, and the temperature sensor 2 is mounted on the elastic member. When the pot bottom is placed on the pot support 100, the elastic member is compressed by the pot support 100, thereby tightly fitting the pot bottom and the temperature sensor 2 mounted on the elastic member. This allows the temperature sensor 2 to more accurately detect the pot bottom temperature. The elastic member is preferably, but not limited to, a spring, preferably a heat-resistant metal spring. The temperature sensor 2 is preferably, but not limited to, a thermal resistor or thermocouple.

[0049] In this embodiment, the control module includes a temperature setter 8. The temperature setter 8 is capable of setting a preset temperature. Preferably, the temperature setter 8 includes a temperature display screen 81. The user can use the temperature setter 8 to modify the preset temperature and use the temperature display screen 81 to monitor the temperature of the pot bottom. The temperature display screen 81 not only allows the user to easily monitor the temperature of the pot bottom in different cooking modes, enabling them to select the appropriate preset temperature for each cooking mode, but also assists the user in controlling the cooking temperature.

[0050] In this embodiment, the wok support 100 preferably also includes a timer. The control module is in communication with the timer and controls the drive mechanism 4 to drive the door 3 to close the ventilation opening 11 when the timer reaches a preset time. This allows users to set cooking times according to different cooking modes without having to stay in front of the gas stove and avoid problems such as dry cooking, thereby improving the user experience.

[0051] Example 2

[0052] Example 2 relates to a gas stove comprising a burner and a wok support 100 surrounding the burner. The wok support 100 is the same as that of Example 1. The gas stove of Example 2 includes the wok support 100 of Example 1, thus achieving the benefits of the wok support 100 of Example 1. It prevents dry burning without the risk of burner blockage and eliminates the extra burden of cleaning the burner and wok support 100 for the user.

[0053] In this embodiment, the gas stove also includes a gas pipeline and a thermoelectric protection device. The gas pipeline is suitable for connecting the burner to the gas source, and the thermoelectric protection device includes a solenoid valve and a thermocouple. Among them, the solenoid valve is arranged in the gas pipeline and is suitable for controlling the on and off of the gas pipeline. The thermocouple is arranged in the burner and is connected to the solenoid valve for communication. Current gas stoves generally use thermocouples to maintain the valve of the gas stove. The battery powers the valve for about 8 seconds, and the flame burns. After 8 seconds, the flame burns the thermocouple, and the thermocouple generates a valve current to maintain the solenoid valve open. When the temperature sensor 2 in the pot support 100 detects that the temperature of the bottom of the pot is higher than the preset temperature, the control module can control the drive mechanism 4 to switch the door body 3 to the first state, isolate the air to extinguish the flame, the thermocouple valve current disappears, and the solenoid valve is closed, so as not to cause gas leakage.

[0054] To sum up, the pot support 100 of Example 1 and the gas stove of Example 2 can overcome the defects of the gas stoves in the prior art that the fire extinguishing agent easily causes the burner to be blocked during automatic fire extinguishing and requires the user to clean the burner. It can avoid the occurrence of dry burning without causing the risk of burner blockage and will not bring the extra burden of cleaning the burner and pot support 100 to the user.

[0055] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
