Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, and in particular to a stove and an ignition control method. Background Technology

[0002] With the continuous development of the kitchen appliance market, customer complaints about burner ignition failure and flameout in cooktops have been increasing year by year. Analysis of these complaints reveals that most ignition failures and flameout issues are caused by clogged ignition holes, a problem that is difficult for users to identify, leading to complaints. Particularly concerning are cases where the inner burner cap is locked or cannot be removed after prolonged use, making it impossible for users to clean the burner holes and causing inconvenience to their user experience.

[0003] Existing technologies typically prevent scalding by using a scalding shield or other protective structures to avoid contact between scalding and the ignition hole, thus preventing clogging. However, this method has limitations, and clogging of the ignition hole can still occur. Summary of the Invention

[0004] The purpose of this invention is to provide a stove and an ignition control method that can solve the problem of ignition holes being blocked and unable to ignite.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A stove, comprising:

[0007] Ignition needle;

[0008] A burner, wherein a mixing chamber is provided inside the burner, and an ignition hole is provided on the burner that communicates with the mixing chamber, the ignition hole facing the ignition needle;

[0009] An auxiliary air outlet component is provided with an auxiliary air outlet hole, which is oriented toward the ignition hole and the ignition needle.

[0010] The valve assembly is switchably connected to either the mixing chamber or the auxiliary outlet to supply fuel gas to either the mixing chamber or the auxiliary outlet.

[0011] As an optional solution for the above-mentioned stove, the ignition hole and the ignition needle are arranged radially along the burner. Along the radial direction of the burner, the auxiliary gas outlet is located between the ignition hole and the ignition needle. Along the circumference of the burner, the auxiliary gas outlet is staggered from the ignition needle and the ignition hole.

[0012] As an alternative to the above-mentioned stove, at least two ignition holes are provided, and the at least two ignition holes are arranged at intervals along the circumference of the burner. Along the circumference of the burner, the ignition needle and all the ignition holes are located on the same side of the auxiliary gas outlet.

[0013] As an alternative to the above-mentioned stove, the width dimension of the auxiliary air outlet along the radial direction of the burner is defined as the width dimension, and the width dimension gradually increases along the airflow direction inside the auxiliary air outlet.

[0014] As an alternative to the aforementioned stove, the stove further includes a blower assembly, which is connected to the auxiliary air outlet to blow air into the ignition port.

[0015] As an optional solution for the above-mentioned stove, the valve assembly includes a valve body and a main passage and a secondary passage respectively connected to the valve body. The main passage is connected to the mixing chamber, and the secondary passage is connected to the auxiliary gas outlet.

[0016] The blower assembly includes a fan, which is connected to the auxiliary air outlet.

[0017] As an alternative to the aforementioned stove, the blower assembly further includes a gas collecting component, which is connected to the auxiliary gas outlet component, the secondary passage, and the blower.

[0018] An ignition control method, applied to the aforementioned stove, the ignition control method comprising:

[0019] After performing the ignition operation, determine whether the ignition was successful;

[0020] If not, the valve assembly switches to communicate with the auxiliary air outlet and activates the ignition needle to generate a flame to burn off the foreign object at the ignition outlet.

[0021] As an optional solution to the above-mentioned ignition control method, the ignition control method further includes:

[0022] After the valve assembly switches to the position where the auxiliary air outlet is connected and maintains this connection for a first preset time, the valve assembly closes and blows air through the auxiliary air outlet toward the ignition port and the ignition needle.

[0023] As an optional embodiment of the above ignition control method, before the valve assembly switches to communicate with the auxiliary outlet port, the following further step is included:

[0024] The first reminder procedure is executed to prompt the user to activate the ignition needle.

[0025] The beneficial effects of this invention are:

[0026] In the stove provided by this invention, when the ignition hole is blocked and ignition fails, the valve assembly switches to connect with the auxiliary gas outlet to supply gas to the auxiliary gas outlet. At this time, the ignition needle is activated, which can ignite the flame on the outside of the burner. The flame can burn the impurities at the ignition hole, so that the impurities at the ignition hole are carbonized, thereby solving the problem of ignition hole blockage.

[0027] After removing impurities from the ignition orifice, the valve assembly switches to communication with the mixing chamber. By introducing combustion gas into the mixing chamber, the combustion gas can push out carbonized impurities and debris from the ignition orifice, thereby further cleaning the ignition orifice.

[0028] The stove also includes a blower assembly, which is connected to the auxiliary gas outlet. The blower assembly can drive airflow through the auxiliary gas outlet of the auxiliary gas outlet component and blow it toward the ignition hole and ignition needle. By blowing, it disperses the impurities after combustion in the ignition hole and between the ignition hole and ignition needle to ensure successful ignition.

[0029] The ignition control method provided by this invention can ignite the gas from the outside of the burner by cooperating with the auxiliary gas outlet and the ignition needle, and burn the impurities at the ignition hole, carbonizing the impurities. This can effectively solve the problem of difficult cleaning of the burner cap and burner holes, greatly reduce the customer complaint rate, and improve the product user experience.

[0043] Example 1

[0044] This embodiment provides a stove, such as Figure 1 As shown, the stove includes a stove body, a burner 300, an ignition needle 200, and a valve assembly 800. The ignition needle 200, burner 300, and valve assembly 800 are all located in the stove body. The burner 300 has a mixing chamber, and the burner 300 has an ignition hole 331 communicating with the mixing chamber (see [reference]). Figure 4 The ignition hole 331 is positioned facing the ignition needle 200; the valve assembly 800 can communicate with the mixing chamber inside the burner 300 to introduce gas into the burner 300; after the ignition needle 200 is activated, it can generate a spark to ignite the gas and form a flame.

[0045] Optionally, such as Figure 1 As shown, the main body of the stove includes a chassis 120 and a panel 110 disposed on the chassis 120. The chassis 120 and the panel 110 form an installation cavity. The valve assembly 800 and part of the burner 300 are located in the installation cavity to improve the modularity of the stove and to protect the burner 300 and the valve assembly 800.

[0046] Optionally, the cooktop also includes a knob 112, one end of which is connected to the valve assembly 800, and the other end extends out of the mounting cavity through the mounting hole 114 on the panel 110. The knob 112 is movable relative to the cooktop body 100 to open and close the valve assembly 800; and the knob 112 is electrically connected to the ignition needle 200 so that when it is rotated relative to the cooktop body 100, the ignition needle 200 is activated to generate a spark, thereby igniting the gas.

[0047] In some embodiments, the knob 112 can rotate and move vertically relative to the cooktop body 100. When the knob 112 is pressed down and rotated, the valve assembly 800 opens and the ignition needle 200 is activated.

[0048] It should be noted that the knob 112, valve assembly 800, and ignition needle 200 are all existing technologies in the field. The present invention can adopt any structure and connection method of the knob 112, valve assembly 800, and ignition needle 200 in the prior art, as long as the user can control the opening and closing of the valve assembly 800 and the starting and stopping of the ignition needle 200 through the knob 112. No specific limitation is made in the present invention.

[0049] In existing stoves, the ignition hole 331 on the burner 300 is prone to clogging. Most ignition failures and inability to maintain the flame are caused by clogging of the ignition hole 331. Although the current burner 300 has been improved with a series of structural improvements such as the anti-soup rim to prevent soup from clogging the ignition hole 331, there are still protective defects and the problem of clogging of the ignition hole 331 cannot be solved.

[0050] To solve the above problems, such as Figures 1-4 As shown, the stove in this embodiment also includes an auxiliary gas outlet 400, which has an auxiliary gas outlet 410 facing the ignition hole 331 and the ignition needle 200. The valve assembly 800 can be switched to communicate with either the mixing chamber or the auxiliary gas outlet 410 to supply gas to either chamber or outlet 410. When ignition hole 331 is blocked, causing ignition failure, the valve assembly 800 switches to communicate with the auxiliary gas outlet 410 to supply gas to the auxiliary gas outlet 400. At this time, the ignition needle 200 is activated, which can ignite a flame on the outside of the burner 300. The flame can burn impurities at ignition hole 331, carbonizing them and resolving the blockage of ignition hole 331.

[0051] It is understandable that the impurities clogging the ignition hole 331 are generally combustible materials. Combustion can carbonize the impurities, preventing them from continuing to clog the ignition hole 331. This eliminates the need for the user to manually disassemble the burner 300 to clean the ignition hole 331, making the operation convenient, efficient, and improving the user experience.

[0052] After the impurities at the combustion ignition hole 331 are removed, the valve assembly 800 switches to communicate with the mixing chamber. By introducing gas into the mixing chamber, the gas can push the carbonized impurities and debris in the ignition hole 331 out, thereby further cleaning the ignition hole 331.

[0053] In some embodiments, the burner 300 includes a gas distribution seat 310, an inner ring burner cap 330, and an outer ring burner cap 320. Both the inner and outer ring burner caps are disposed on the gas distribution seat 310 and, together with the gas distribution seat 310, form an outer ring mixing chamber and an inner ring mixing chamber, respectively. The outer ring mixing chamber is fitted outside the inner ring mixing chamber. An ignition hole 331 is disposed on the inner ring burner cap 330. Correspondingly, an ignition needle 200 and an auxiliary gas outlet 400 pass through the gas distribution seat 310 and are located between the inner ring burner cap 330 and the outer ring burner cap 320.

[0054] The exhaust range of the auxiliary exhaust port 410 covers the ignition port 331 and the ignition needle 200. On the one hand, it ensures that the gas flowing out of the auxiliary exhaust port 410 can be ignited by the ignition needle 200 more quickly and rapidly, preventing gas leakage. On the other hand, it ensures that the flame formed after the gas is ignited at the auxiliary exhaust port 410 can contact the ignition port 331 to burn off the impurities in the ignition port 331.

[0055] In some embodiments, such as Figure 4As shown, the ignition needle 200 and ignition hole 331 are arranged radially along the burner 300 (specifically, radially along the inner ring burner cap 330), so that the ignition needle 200 and ignition hole 331 are positioned opposite each other, facilitating the spark generated by the ignition needle 200 to ignite the gas flowing out of the ignition hole 331; along the radial direction of the burner 300, the auxiliary gas outlet 400 is located between the ignition hole 331 and the ignition needle 200, so that the distance between the auxiliary gas outlet 400 and the ignition needle 200 and the ignition hole 331 is relatively small. The auxiliary gas outlet 400 is small, which facilitates its engagement with the ignition hole 331 and the ignition needle 200. Along the circumference of the burner 300 (specifically, the circumference of the inner ring burner cap 330), the auxiliary gas outlet 400 is staggered from the ignition hole 331 and the ignition needle 200. In other words, the auxiliary gas outlet 410 is not directly opposite the ignition hole 331 and the ignition needle 200 along the radial direction of the burner 300, thereby avoiding interference between the auxiliary gas outlet 400 and the engagement of the ignition needle 200 and the ignition hole 331.

[0056] In some embodiments, in order to ignite more efficiently, the number of ignition holes 331 is provided to be at least two, and the at least two ignition holes 331 are arranged at intervals along the circumference of the burner 300, so as to avoid the situation that ignition cannot occur when only a single ignition hole 331 is provided.

[0057] It is understandable that ignition failure will only occur when all ignition holes 331 are blocked. By providing at least two ignition holes 331, the probability of ignition failure can be reduced, thereby improving the reliability of the burner 300.

[0058] For example, the number of ignition holes 331 can be two, three, four or more, and the present invention does not specifically limit the number.

[0059] In order to ensure that the gas flowing out of the auxiliary gas outlet 400 can both burn towards the ignition hole 331 and be ignited by the ignition needle 200, in some embodiments, the ignition needle 200 and all the ignition holes 331 are located on the same side of the auxiliary gas outlet 410 along the circumference of the inner ring burner cap 330, so that the gas flowing out of the auxiliary gas outlet 410 can flow towards both the ignition needle 200 and the ignition hole 331.

[0060] In some embodiments, multiple ignition holes 331 are symmetrically arranged relative to the ignition needle 200 along the circumference of the inner ring burner cap 330. That is, the axis of the ignition needle 200 is approximately the axis of symmetry of the multiple ignition needles 200. This arrangement ensures that the distance between the ignition needle 200 and each ignition hole 331 is not too large, making it convenient for the ignition needle 200 to ignite the gas flowing out of any ignition hole 331.

[0061] To ensure that the gas flowing from the auxiliary vent 410 can both burn towards the ignition port 331 and be ignited by the ignition needle 200, in some embodiments, the width of the auxiliary vent 410 along the radial direction of the burner 300 is defined as its width, which gradually increases along the airflow direction within the auxiliary vent 410. In other words, the size of the auxiliary vent 410 along the radial direction of the inner ring burner cap 330 gradually changes, with a smaller size at the end of the auxiliary vent 410 closer to the inside of the auxiliary vent 400 and a larger size at the end closer to the outside of the auxiliary vent 400. This ensures that the airflow from the auxiliary vent 410 is outward-expanding, better covering the areas where the ignition port 331 and the ignition needle 200 are located.

[0062] To better address the issue of clogging in the ignition hole 331, the cooktop also includes a blower assembly 900. The blower assembly 900 is connected to an auxiliary air outlet 410, and it drives airflow through the auxiliary air outlet 410 to the ignition hole 331 and the ignition needle 200. This design effectively disperses combustion debris within the ignition hole 331 and between the ignition hole 331 and the ignition needle 200 through a blowing process, ensuring successful ignition.

[0063] In some embodiments, such as Figure 2 and Figure 3 As shown, the valve assembly 800 includes a valve body 810 and a main passage 820 and a secondary passage 830 respectively connected to the valve body 810. The main passage 820 is connected to the mixing chamber, and the secondary passage 830 is connected to the auxiliary air outlet 400. The blower assembly 900 includes a blower 920, which is connected to the auxiliary air outlet 400. When the impurities in the ignition port 331 have been burned and carbonized, the blower 920 is started, sending airflow into the auxiliary air outlet 400 to purge the ignition port 331 through the auxiliary air outlet 410.

[0064] To simplify the structure, in some embodiments, the blower assembly 900 further includes a gas collecting component 930, which is connected to the auxiliary gas outlet component 400, the secondary passage 830, and the blower 920. When the valve body 810 is connected to the secondary passage 830, the gas passes through the secondary passage 830 and the gas collecting component 930 before entering the auxiliary gas outlet component 400. After the impurities in the ignition hole 331 have been burned and carbonized, the blower 920 starts, sending the airflow through the gas collecting component 930 into the auxiliary gas outlet component 400 to purge the ignition hole 331 through the auxiliary gas outlet hole 410. By providing the gas collecting component 930, the blower 920 and the secondary passage 830 can be easily connected to the auxiliary gas outlet component 400, simplifying the connection structure.

[0065] Optionally, the gas collecting component 930 can be a structure with an internal cavity, such as a box or a three-way pipe, as long as it can connect the auxiliary gas outlet component 400, the fan 920 and the secondary passage 830.

[0066] In some embodiments, the blower assembly 900 further includes a mounting bracket 910 disposed within the chassis 120. The blower 920 and the air collection component 930 are both disposed on the mounting bracket 910, which is used to fix the blower 920 and the air collection component 930.

[0067] Optionally, the mounting bracket 910 and the chassis 120 can be connected by fasteners such as screws, or fixed by snap-fit ​​or welding.

[0068] To determine whether ignition is successful, the cooktop also includes a thermocouple 500, which is located on one side of the ignition port 331. The valve assembly 800 also includes a solenoid valve that controls whether the valve body 810 is connected to the main passage 820. The thermocouple 500 is electrically connected to the solenoid valve, which is normally closed. After ignition, when the thermocouple 500 detects an increase in ambient temperature, it sends an electrical signal to keep the solenoid valve open, thus connecting the valve body 810 to the main passage 820. This process is called successful valve engagement by the thermocouple 500. Conversely, if the thermocouple 500 detects no change in ambient temperature after ignition, it will not engage the valve, and the solenoid valve will remain closed.

[0069] Optionally, the thermocouple 500 and the valve assembly 800 can be electrically connected through a control component. The thermocouple 500 detects the temperature and sends an electrical signal to the control component. After receiving the electrical signal, the control component controls the solenoid valve in the valve assembly 800 to open or close.

[0070] It should be noted that thermocouple 500 and valve assembly 800 are both existing technologies in the field. The present invention can use any existing structure and connection relationship of thermocouple 500 and valve assembly 800, which will not be described here.

[0071] In some embodiments, the burner 300 further includes an ejector assembly 340, which connects the main passage 820 and the mixing chamber. The ejector assembly 340 can introduce the combustion gas and the adsorbed air into the mixing chamber so that the combustion gas in the mixing chamber can be mixed with the air to ensure complete combustion of the combustion gas.

[0072] It should be noted that the ejector component 340 is prior art in this field. The present invention can use any structure of the ejector component 340 in the prior art, which will not be described here.

[0073] In some embodiments, the cooktop also includes a drip tray 600, which is disposed on the panel 110. The gas distributor 310 in the burner 300 is located above the drip tray 600. The connection point between the gas distributor 310 in the burner 300 and the ejector assembly 340 passes through the drip tray 600 and the clearance hole 113 on the panel 110 in sequence, so as to connect the ejector assembly 340 in the mounting cavity to the gas distributor 310 above the drip tray 600. The drip tray 600 can catch the soup spilled on the burner 300 during cooking, preventing the soup from entering the mounting cavity, thereby preventing the soup from contacting the electrical components in the mounting cavity and ensuring the safety and reliability of the cooktop.

[0074] In some embodiments, the cooktop also includes a display panel 111 disposed on the panel 110. The display panel 111 is used to display information about blockage in the ignition hole 331 and to remind the user to activate the ignition needle 200 to burn off the impurities in the ignition hole 331.

[0075] Optionally, the display panel 111 is electrically connected to the control component, which determines whether the ignition port 331 is blocked based on whether the solenoid valve is successfully activated. If the ignition port 331 is blocked, the control component controls the display panel 111 to display information indicating the blockage, reminding the user to clean the ignition port 331. This prompts the user to press down the rotary knob 112 to activate the ignition needle 200, thereby igniting the gas flowing from the auxiliary gas outlet 410.

[0076] Optionally, such as Figure 2 , Figure 3 and Figure 5 As shown, the control assembly includes a main control board 710 and a secondary control board 720 that are electrically connected. The secondary control board 720 is electrically connected to the display board 111, and the main control board 710 is electrically connected to the thermocouple 500, the valve assembly 800, and the ignition needle 200, respectively.

[0077] Example 2

[0078] This embodiment provides an ignition control method that can be applied to the stove in Embodiment 1. It can achieve automatic cleaning of the ignition hole 331 without disassembling the burner 300, making it easy to operate and ensuring the normal use of the stove.

[0079] Specifically, such as Figure 6 As shown, the ignition control method includes:

[0080] S1: After performing the ignition operation, determine whether the ignition was successful;

[0081] If ignition is successful, then ignition hole 331 is not blocked and the stove can work normally; if ignition fails, then ignition hole 331 is blocked and needs to be cleaned to avoid delaying normal use by the user.

[0082] S2: If not, the valve assembly 800 switches to connect with the auxiliary air outlet 410 and activates the ignition needle 200 to generate a flame to burn the foreign object at the ignition hole 331.

[0083] If ignition fails, it is determined that the ignition hole 331 is blocked. The valve assembly 800 switches the valve path, allowing the gas to flow out through the auxiliary gas outlet 410 and be ignited by the ignition needle 200. The flame burns the impurities in the ignition hole 331, carbonizing them and resolving the blockage problem.

[0084] In some embodiments, step S1 can be used to determine whether ignition is successful by detecting whether the thermocouple 500 successfully draws the valve.

[0085] Specifically, the thermocouple 500 works in conjunction with the solenoid valve in the valve assembly 800 that controls whether the valve body 810 and the main passage 820 are open or closed. When the thermocouple 500 detects an increase in ambient temperature, it determines that ignition is successful and the flame increases the ambient temperature. At this time, the electrical signal generated by the thermocouple 500 is transmitted to the main control board 710, and the main control board 710 controls the solenoid valve to remain open, thus completing the thermocouple 500's suction valve operation. Conversely, if the thermocouple 500 does not detect an increase in ambient temperature, it determines that no flame is generated near the thermocouple 500, and the solenoid valve remains in the normally closed state.

[0086] In some embodiments, step S1, which involves performing the ignition operation, means that the user presses down and rotates the knob 112, the valve body 810 opens under the action of the knob 112, and the ignition needle 200 starts to generate sparks.

[0087] In some embodiments, such as Figure 7 As shown, in order to ensure that the flame fully burns the impurities in the ignition hole 331, in step S2, the valve assembly 800 switches to be connected to the auxiliary air outlet 410 and maintains it for a first preset time to ensure that the flame has sufficient combustion time, thereby solving the problem of ignition hole 331 blockage.

[0088] Optionally, the first preset duration can be 20-60 seconds, preferably 40-60 seconds, to ensure that impurities are fully combusted. For example, typical non-limiting values ​​for the first preset duration are 20 seconds, 25 seconds, 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, and 60 seconds.

[0089] In some embodiments, the method further includes the following steps before step S2:

[0090] The first alert procedure is executed to prompt the user to activate the ignition needle 200.

[0091] Optionally, the first reminder procedure may include reminding the user that the ignition hole 331 is blocked by means of text, voice, light or beep, and reminding the user that the ignition needle 200 needs to be activated to clear the ignition hole 331.

[0092] To ensure effective cleaning of the ignition hole 331, some embodiments further include the following after step S2:

[0093] S3: Valve assembly 800 is closed and blows air towards ignition port 331 and ignition needle 200 through auxiliary air outlet 410.

[0094] By blowing air through the auxiliary air outlet 410 toward the ignition hole 331 and the ignition needle 200, the airflow can sweep away the carbonized debris at the ignition hole 331 and the ignition needle 200, thereby further cleaning the ignition hole 331 and the ignition needle 200 and ensuring smooth ignition.

[0095] In some embodiments, in order to ensure the purging effect, the duration of blowing air through the auxiliary air outlet 410 toward the ignition hole 331 and the ignition needle 200 is a second preset duration, so as to ensure sufficient purging time and improve the cleaning effect on the ignition hole 331.

[0096] Optionally, the second preset duration can be 10-60s, preferably 30-60s, to ensure that impurities are thoroughly cleaned. For example, typical non-limiting values ​​for the second preset duration are 10s, 15s, 20s, 25s, 30s, 35s, 40s, 45s, 50s, 55s, and 60s.

[0097] In some embodiments, the method further includes the following after step S2 or step S3:

[0098] S4: Proceed to step S1.

[0099] By relighting and determining whether ignition is successful, check if the ignition hole 331 is clean. If the ignition hole 331 is still blocked, clean the ignition hole 331 again following the above steps. If ignition is successful, the stove can be used normally.

[0100] It should be noted that during the re-ignition process, the valve assembly 800 switches to a state connected to the mixing chamber, so that gas can be introduced into the mixing chamber through the main passage 820. During this process, the gas flows through the mixing chamber to the ignition port 331, and the gas can push out carbonized impurities and debris in the ignition port 331 to further clean the ignition port 331.

[0101] In some embodiments, the process further includes the following steps between step S3 and step S4:

[0102] The second reminder procedure is executed to remind the user that ignition hole 331 has been cleaned and ignition can be performed.

[0103] Optionally, the second reminder procedure may include reminding the user, through text, voice, light or beep, that the ignition hole 331 has been cleaned and that the user needs to start the ignition needle 200 to ignite.

[0104] In some embodiments, the method further includes the following steps before step S2:

[0105] The system determines the number of ignition failures within a third preset time period. If the number of failures exceeds the preset number, a third reminder procedure is executed to remind the user to check if the ignition needle 200 is de-energized.

[0106] Optionally, the third reminder procedure may include reminding the user to check whether the ignition needle 200 is powered off via text, voice, light, or beep.

[0107] Optionally, the third preset duration can be 3-5 minutes, preferably 4-5 minutes, to avoid cleaning the ignition hole 331 for a long time and multiple times due to power failure of the ignition needle 200.

[0108] Optionally, the preset number of times can be 2-5 times, preferably 2-3 times, to avoid cleaning the ignition hole 331 for a long time and multiple times due to power failure of the ignition needle 200.
