Description

Technical Field

[0001] The utility model relates to a stove. Background Art

[0002] The stir-fry mode of existing stoves generally uses a strong suction valve and a button to realize the switching of the stir-fry channel. First, the energy consumption is relatively high (the strong suction valve requires AC power, and the bistable valve increases battery power consumption). Second, the panel button operation experience is poor (the buttons do not work after the panel is dirty, etc.). Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a stove in order to overcome the defects of the existing stove in the stir-fry mode that the stir-fry mode consumes more power and has a poor operating experience.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A stove, comprising a stove panel, a fire cover, a gas cock and a stir-fry valve;

[0006] The gas cock valve has a gas inlet, a gas outlet and a stir-fry outlet, the gas inlet is connected to the gas pipeline, the gas outlet is connected to the fire cover, the stir-fry outlet is connected to the gas inlet of the stir-fry valve, and the stir-fry valve outlet is connected to the fire cover;

[0007] The stir-fry valve includes a first valve body, a valve stem and a valve core; the first valve body has a first valve cavity inside, and the air inlet of the stir-fry valve and the air outlet of the stir-fry valve are connected through the first valve cavity; the valve core is arranged in the first valve cavity, the lower end of the valve stem is connected to the valve core, the upper end of the valve stem passes through the first valve body and extends to the top of the stove panel, and the valve stem can drive the valve core to move between a first position and a second position in a vertical direction relative to the first valve body; when the valve core is located at the first position, the air outlet of the stir-fry valve is closed; when the valve core is located at the second position, the air outlet of the stir-fry valve is opened.

[0008] In this solution, the user can press the valve stem to drive the valve core to move and open the stir-fry valve. Compared with the traditional button-type stir-fry mode switch, the operation is more convenient and there will be no button failure, which improves the reliability of the stir-fry valve. In addition, the opening of the stir-fry valve by manual pressing can reduce the number of electrical components of the stir-fry valve and reduce the power consumption of the stir-fry valve.

[0009] Preferably, the stir-fry valve also includes a retaining member, which is arranged below the valve core and fixed on the first valve body, and the retaining member is at least partially located in the first valve cavity. The retaining member can be attracted to the valve core to keep the valve core in the second position.

[0010] In this solution, the retainer is used to ensure that the gas outlet of the stir-fry valve is maintained in a normally open state, which facilitates the flow of gas and prevents the stir-fry valve from being closed by hand. The suction method is simple to operate, has low difficulty in alignment, and is easy to operate.

[0011] Preferably, the stir-fry valve further comprises a thermocouple, the thermocouple comprising a fixed portion, a movable portion and a reset portion, the movable portion being movably connected to the upper end of the fixed portion through the reset portion, the lower end of the fixed portion being fixedly connected to the first valve body, and the valve stem being connected to an end of the movable portion away from the fixed portion in the vertical direction;

[0012] The fixed part forms the retaining member, and the movable part forms the valve core; when the sensing temperature of the thermocouple is greater than or equal to a preset temperature, the fixed part and the movable part are attracted; when the sensing temperature of the thermocouple is lower than the preset temperature, the fixed part and the movable part are not attracted.

[0013] In this solution, when the stove is working, the temperature rises. According to the characteristics of the thermocouple, after the user presses the valve stem, the valve core can be adsorbed on the retaining member to keep the air outlet of the stir-fry valve open. After the stove finishes working, the temperature drops, the retaining member no longer adsorbs the valve core, and the valve core is reset to the first position under the action of the reset part to close the air outlet of the stir-fry valve. The thermocouple structure can adapt to the environment with higher temperature and is suitable for stoves.

[0014] Preferably, the thermocouple is disposed at the lower end of the first valve cavity and is partially located outside the first valve cavity, and the thermocouple is closed and connected to the lower end port of the first valve cavity.

[0015] Preferably, the retaining member is a magnet, and the valve core is made of metal.

[0016] In this solution, the valve core is magnetically attracted to the retaining member, which has a simple structure and is easy to operate. The user can pull the valve stem upward to reset the valve core, which is more reliable. The opening and closing process of the stir-fry valve is entirely manual, which further reduces the power consumption of the stir-fry valve.

[0017] Preferably, the stir-fry valve further comprises a sealing member, which is arranged in the first valve cavity and above the valve core, and is sleeved on the valve stem, and can move along the vertical direction with the valve stem;

[0018] When the valve core is located at the first position, the sealing member blocks the air outlet of the stir-fry valve.

[0019] In this solution, the seal is used to prevent gas leakage and improve safety.

[0020] Preferably, the stir-fry valve further comprises a limiter, which is fixed to the upper end surface of the retainer; the limiter has a concave cavity with an opening facing downward, the upper end surface of the limiter has a through hole penetrating in a vertical direction, the valve stem passes through the through hole and extends into the concave cavity, and the valve core is arranged in the concave cavity;

[0021] When the valve core is in the first position, the upper end surface of the valve core abuts against the upper wall surface of the concave cavity.

[0022] In this solution, the limiter can limit the excessive upward movement of the valve core when the user pulls up the valve stem, so as to prevent the sealing member, the valve core and other structures from being pulled out of the first valve cavity, thereby ensuring the reliability of use.

[0023] Preferably, the stir-fry valve also includes a reset member, which is sleeved on the valve stem, and whose two ends in the vertical direction are respectively abutted against the sealing member and the limit member, and the reset member is used to apply a force to the sealing member in a direction away from the limit member.

[0024] In this solution, the reset element indirectly resets the valve core by applying force to the sealing element, preventing the user from failing to pull up the valve properly, causing the air outlet of the stir-fry valve to not be completely closed, thereby improving the safety of the stove.

[0025] Preferably, the fire cover comprises an outer ring fire cover, the gas outlet comprises an outer ring outlet, and the outer ring outlet is connected to the outer ring fire cover;

[0026] The cooker further comprises an adapter, an outer ring nozzle and an outer ring ejector tube, the adapter comprises an adapter cavity, an outer ring air inlet, a stir-fry air inlet and a nozzle air outlet, the outer ring air inlet, the stir-fry air inlet and the nozzle air outlet are connected through the adapter cavity, the nozzle is arranged at the nozzle air outlet, and the nozzle can eject gas toward the outer ring ejector tube;

[0027] The outer ring air outlet is communicated with the outer ring air inlet, and the air outlet of the stir-fry valve is communicated with the stir-fry air inlet.

[0028] In this solution, the air outlet of the stir-fry valve is arranged before the outer ring nozzle, so that the gas provided by the stir-fry valve will pass through the outer ring nozzle to intercept and limit the flow rate before flowing into the outer ring fire cover. Therefore, no matter what flow rate of the gas in the outer ring fire cover is, the gas flow rate out of the outer ring fire cover after opening the stir-fry valve is basically stable, which improves the user's stir-frying experience and improves energy efficiency.

[0029] Preferably, the gas cock valve comprises a second valve body, a solenoid valve assembly and a cock valve assembly;

[0030] The second valve body has a second valve cavity, a third valve cavity, a fourth valve cavity and the gas inlet, the second valve cavity is connected to the gas inlet, the third valve cavity is connected to the gas outlet, the fourth valve cavity is connected to the stir-fry outlet, the third valve cavity and the fourth valve cavity are both connected to the second valve cavity and are independently arranged;

[0031] The solenoid valve assembly is arranged in the second valve chamber, and the plug valve assembly is arranged in the third valve chamber.

[0032] In this solution, the fourth valve chamber connected to the stir-fry valve is set after the gas flows out of the second valve chamber and before it flows into the third valve chamber. On the one hand, when the cooker is not in use, the solenoid valve assembly and the valve core of the stir-fry valve can achieve two-way sealing of the gas flow to prevent gas leakage, and the airtight safety is better. On the other hand, the gas flowing into the stir-fry valve is not restricted by the plug valve assembly, ensuring that the gas flowing into the stir-fry valve is sufficient, improving the stir-fry experience.

[0033] The positive effect of the utility model is that the user can drive the valve core to move by pressing the valve stem to open the stir-fry valve. Compared with the traditional button-type stir-fry mode switch, the operation is more convenient and there will be no button failure, which improves the reliability of the stir-fry valve. In addition, the stir-fry valve can be opened by manual pressing, which can reduce the number of electrical components of the stir-fry valve and reduce the power consumption of the stir-fry valve.

[0092] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0093] Example 1

[0094] like Figure 1 and Figure 2 As shown, the present embodiment discloses a stove, including a stove panel 11, a fire cover, a gas cock 2 and a stir-fry valve 3. The gas outlet of the gas cock 2 and the gas outlet 392 of the stir-fry valve are both connected to the fire cover, and the gas cock 2 and the stir-fry valve 3 are used to provide gas to the fire cover. The gas cock 2 is used to control the gas entering the stove, and can adjust the gas flux according to the needs of the user to adjust the size of the flame at the fire cover. The stir-fry valve 3 can increase the amount of gas at the fire cover to adjust the flame at the fire cover to the maximum value, and turn on the stir-fry mode during cooking.

[0095] Specifically, Figure 1 and Figure 2 As shown, the fire cover is installed above the stove panel 11 to generate flames. The fire cover includes an inner ring fire cover 12 and an outer ring fire cover 13, and the outer ring fire cover 13 is sleeved on the radial outer side of the inner ring fire cover 12.

[0096] like Figure 1-Figure 7 As shown, the gas cock valve 2 includes a second valve body 21 , a solenoid valve assembly 22 and a cock valve assembly 23 .

[0097] like Figure 2-Figure 7 As shown, the second valve body 21 has a second valve cavity 211, a third valve cavity 212, a fourth valve cavity 213, a gas inlet 214, a gas outlet and a stir-fry outlet 217, the solenoid valve assembly 22 is arranged in the second valve cavity 211, and the plug valve assembly 23 is arranged in the third valve cavity 212.

[0098] The gas inlet 214 is also the gas inlet of the second valve cavity 211, the gas inlet 214 is connected to the gas pipeline 14, and the solenoid valve assembly 22 is used to control the opening and closing of the gas outlet of the second valve cavity 211. When the gas outlet of the second valve cavity 211 is opened, the gas in the second valve cavity 211 can flow to the third valve cavity 212 and the fourth valve cavity 213. When the gas outlet of the second valve cavity 211 is closed, the gas in the second valve cavity 211 cannot flow to the third valve cavity 212 and the fourth valve cavity 213.

[0099] The gas outlet is the outlet of the third valve chamber 212, and the gas outlet is connected to the fire cover. The plug valve assembly 23 is used to control the amount of gas flowing from the third valve chamber 212 to the fire cover to control the size of the flame at the fire cover. Figure 2 and Figure 4 As shown, the stove also includes an ejector pipe and a nozzle (not shown in the figure), the ejector pipe is connected to the fire cover, the gas from the gas outlet enters the interior of the ejector pipe through the nozzle, and then flows into the fire cover through the ejector pipe.

[0100] The ejector pipe includes an inner ring ejector pipe 51 and an outer ring ejector pipe 52, the nozzle includes an inner ring nozzle and an outer ring nozzle, and the gas outlet includes an inner ring outlet 215 and an outer ring outlet 216. The inner ring ejector pipe 51 is connected to the inner ring fire cover 12, and the inner ring outlet 215 sprays the gas into the inner ring ejector pipe 51 through the inner ring nozzle, and then flows to the inner ring fire cover 12 through the inner ring ejector pipe 51. The outer ring ejector pipe 52 is connected to the outer ring fire cover 13, and the outer ring outlet 216 sprays the gas into the outer ring ejector pipe 52 through the outer ring nozzle, and then flows to the outer ring fire cover 13 through the outer ring ejector pipe 52.

[0101] Furthermore, if Figure 2 and Figure 3 As shown, the stove also includes an adapter 6, which includes a gas channel. The gas channel has a gas inlet 214 and a nozzle outlet. The gas inlet 214 is connected to the gas outlet of the gas cock 2. The nozzle is arranged at the nozzle outlet, and the nozzle can spray gas toward the injection pipe.

[0102] Specifically, the gas channel includes an inner ring gas channel 61 and an outer ring gas channel 62. The inner ring gas channel 61 includes an inner ring air inlet 63 and an inner ring nozzle air outlet 64. The outer ring gas channel 62 includes an outer ring air inlet 65 and an outer ring nozzle air outlet 66. The inner ring air inlet 63 is connected to the inner ring air outlet 215 of the gas cock 2. The inner ring nozzle is arranged at the inner ring nozzle air outlet 64 to spray gas into the inner ring ejector pipe 51. The outer ring air inlet 65 is connected to the outer ring air outlet 216 of the gas cock 2. The outer ring nozzle is arranged at the outer ring nozzle air outlet 66 to spray gas into the outer ring ejector pipe 52.

[0103] It should be noted that the specific structure of the solenoid valve assembly 22, the specific structure of the plug valve assembly 23, and the connection and communication methods between the solenoid valve assembly 22 and the plug valve assembly 23 are all existing technologies in the field and will not be elaborated here.

[0104] like Figure 3 As shown, the stir-fry air outlet 217 is the air outlet of the fourth valve chamber 213, the stir-fry air outlet 217 is connected to the air inlet 391 of the stir-fry valve, the air outlet 392 of the stir-fry valve is connected to the fire cover, and the stir-fry valve 3 is used to control whether the cooking enters the stir-fry mode, that is, whether to adjust the flame at the fire cover to the maximum value.

[0105] Furthermore, if Figure 7As shown, the third valve chamber 212 and the fourth valve chamber 213 in this embodiment are both connected to the second valve chamber 211 and are independently arranged, that is, the fourth valve chamber 213 connected to the stir-fry valve 3 is arranged after the gas flows out of the second valve chamber 211 and before it flows into the third valve chamber 212. When the stove is not in use, the solenoid valve assembly 22 and the valve core 34 of the stir-fry valve 3 can achieve two-point sealing for the flow of gas to prevent gas leakage, and the airtight safety is better. When the stove is in use, the gas flowing into the stir-fry valve 3 is not restricted by the plug valve assembly 23, ensuring that the gas flowing into the stir-fry valve 3 is sufficient, thereby improving the stir-fry experience.

[0106] like Figure 8-Figure 10 As shown, the stir-fry valve 3 includes a first valve body 31 , a valve stem 33 , a valve core 34 , a retaining member 35 and a reset member 36 .

[0107] like Fig. 9 and Fig.10 As shown, the first valve body 31 has a first valve cavity 32 inside, the first valve cavity 32 extends in the vertical direction, and the upper end of the first valve cavity 32 has an opening, and the air inlet 391 of the stir-fry valve and the air outlet 392 of the stir-fry valve can only be connected through the first valve cavity 32. The valve core 34 is arranged in the first valve cavity 32, the valve stem 33 extends in the vertical direction, the lower end of the valve stem 33 is connected to the valve core 34, and the upper end of the valve stem 33 passes through the first valve body 31 and extends above the stove panel 11. The valve stem 33 can move in the vertical direction relative to the valve body, and because the valve stem 33 and the valve core 34 are fixedly connected, the valve stem 33 can drive the valve core 34 to move between the first position and the second position in the vertical direction relative to the first valve body 31.

[0108] When the valve core 34 is in the first position, the valve core 34 blocks the opening at the upper end of the first valve cavity 32, and the gas cannot flow from the air inlet 391 of the stir-fry valve to the air outlet 392 of the stir-fry valve, that is, the air outlet 392 of the stir-fry valve is closed. When the valve core 34 is in the second position, the opening at the upper end of the first valve cavity 32 is opened, and the gas flows from the air inlet 391 of the stir-fry valve to the air outlet 392 of the stir-fry valve through the first valve cavity 32, that is, the air outlet 392 of the stir-fry valve is opened.

[0109] like Fig. 9 As shown, the retainer 35 is disposed below the valve core 34 and fixed on the first valve body 31, and the retainer 35 is at least partially located in the first valve cavity 32. When the valve core 34 moves to the second position, the retainer 35 can be attracted to the valve core 34 to keep the valve core 34 in the second position, so that the gas outlet 392 of the stir-fry valve is maintained in a normally open state, which is convenient for the flow of gas and prevents the stir-fry valve 3 from being closed by hand. The attraction method is simple to operate, has low difficulty in alignment, and is easy to operate.

[0110] like Fig. 9 and Fig.10As shown, the reset member 36 is disposed between the valve core 34 and the retaining member 35, and the two ends of the reset member 36 in the vertical direction are respectively in contact with the lower end surface of the valve core 34 and the upper end surface of the retaining member 35. The reset member 36 is used to apply a force to the valve core 34 in the vertical direction toward the air outlet of the first valve cavity 32 to help the valve core 34 reset from the second position to the first position, and can keep the valve core 34 in the first position to keep the air outlet of the first valve cavity 32 normally closed, so as to ensure that the stir-fry mode is closed.

[0111] The reset member 36 in this embodiment is a coil spring. In other alternative implementations, the reset member 36 may also be other reset structures that can achieve the above functions.

[0112] Specifically, Fig. 9 and Fig.10 As shown, the stir-fry valve 3 also includes a thermocouple 4, which has a fixed portion 41, a movable portion 42 and a reset portion 43. The fixed portion 41 forms a retainer 35, the movable portion 42 forms a valve core 34, and the reset portion 43 forms a reset member 36. Specifically, the lower end of the first valve cavity 32 is open, the fixed portion 41 is arranged at the lower end of the first valve cavity 32 and is partially located outside the first valve cavity 32, the lower end of the fixed portion 41 is fixedly connected to the first valve body 31 and the connection with the lower end port of the first valve cavity 32 is closed to prevent gas leakage. The lower end of the reset portion 43 is connected to the upper end of the fixed portion 41, the movable portion 42 is connected to the upper end of the reset portion 43 and is movably connected to the upper end of the fixed portion 41 through the reset portion 43, and the valve stem 33 is connected to one end of the movable portion 42 away from the fixed portion 41 in the vertical direction.

[0113] When the sensed temperature of the thermocouple 4 is greater than or equal to the preset temperature, the fixed portion 41 and the movable portion 42 are attracted, the valve core 34 moves from the first position to the second position, and the air outlet of the first valve cavity 32 is opened. When the sensed temperature of the thermocouple 4 is lower than the preset temperature, the fixed portion 41 is not attracted to the movable portion 42, the valve core 34 remains in the first position, and the air outlet of the first valve cavity 32 is closed.

[0114] When the stove is working, the temperature rises. According to the characteristics of the thermocouple 4, after the user presses the valve stem 33, the valve core 34 can be adsorbed on the retaining member 35 to keep the air outlet 392 of the stir-fry valve open. After the stove finishes working, the temperature drops, the retaining member 35 no longer adsorbs the valve core 34, and the valve core 34 is reset to the first position under the action of the reset part 43 to close the air outlet 392 of the stir-fry valve. The structure of the thermocouple 4 can adapt to the environment with higher temperature and is suitable for stoves.

[0115] The working principle of the thermocouple 4 belongs to the prior art and will not be described in detail here.

[0116] In this embodiment, the user can press the valve stem 33 to drive the valve core 34 to move, so as to open the stir-fry valve 3. Compared with the traditional button-type stir-fry mode switch, the operation is more convenient, and the button does not fail, thereby improving the reliability of the stir-fry valve 3. Moreover, the opening of the stir-fry valve 3 by manual pressing can reduce the number of electrical components of the stir-fry valve 3 and reduce the power consumption of the stir-fry valve 3.

[0117] Furthermore, if Fig. 9 As shown, the stir-fry valve 3 further includes a pressing portion 7, which is fixed to the upper end of the valve stem 33, and the diameter of the pressing portion 7 is greater than the diameter of the valve stem 33. The pressing portion 7 increases the user's operating area and improves the user's operating experience.

[0118] The pressing portion 7 and the valve stem 33 in this embodiment are separately processed and then assembled, and the pressing portion 7 and the valve stem 33 can be fixedly connected by threaded connection, etc. In other alternative embodiments, the pressing portion 7 and the valve stem 33 can also be integrally formed.

[0119] Furthermore, if Fig.11 As shown, the adapter 6 also includes an adapter cavity 67 and a stir-fry gas channel 68. The stir-fry gas channel 68 has a stir-fry air inlet 69, and the stir-fry air inlet 69 is connected to the stir-fry valve outlet 392. The outer ring air inlet 65, the stir-fry air inlet 69 and the outer ring nozzle outlet 66 are connected through the adapter cavity 67, that is, the gas in the outer ring gas channel 62 and the gas in the stir-fry gas channel 68 can be mixed before flowing out of the outer ring nozzle outlet 66, and then uniformly injected to the outer ring injection pipe 52 through the outer ring nozzle.

[0120] In this embodiment, the air outlet 392 of the stir-fry valve is arranged before the outer ring nozzle, so that the gas provided by the stir-fry valve 3 will pass through the outer ring nozzle to intercept and limit the flow rate before flowing into the outer ring fire cover 13. Therefore, no matter what flow rate the gas in the outer ring fire cover 13 is at, the gas flow rate out of the outer ring fire cover 13 after opening the stir-fry valve 3 is basically stable, thereby improving the user's stir-frying experience and enhancing energy efficiency.

[0121] Example 2

[0122] The structure of the cooker in this embodiment is basically the same as that in Embodiment 1, except that:

[0123] like Fig.12 and Fig.13 As shown, the stir-fry valve 3 includes a first valve body 31 , a valve stem 33 , a valve core 34 , a retaining member 35 , a sealing member 37 , a limiting member 38 and a reset member 36 .

[0124] like Fig.12As shown, the retaining member 35 in this embodiment is a magnet, and the material of the valve core 34 is a metal material. The valve core 34 is attracted to the retaining member 35 by magnetic attraction, which has a simple structure and is easy to operate. The user can pull the valve stem 33 upward to reset the valve core 34, which has higher reliability. The process of opening and closing the stir-fry valve 3 is entirely manual, which further reduces the power consumption of the stir-fry valve 3.

[0125] like Fig.12 As shown, the seal 37 is arranged in the first valve cavity 32 and above the valve core 34. The seal 37 is sleeved on the valve stem 33, and the seal 37 can move along the vertical direction with the valve stem 33. When the valve core 34 is in the first position, the seal 37 blocks the opening at the upper end of the first valve cavity 32, thereby closing the gas outlet 392 of the stir-fry valve. The seal 37 is used to prevent gas leakage and improve safety.

[0126] like Fig.12 As shown, the stopper 38 is fixed on the upper end surface of the retaining member 35, and the stopper 38 has a concave cavity 381 with an opening facing downward, and the upper end surface of the stopper 38 has a through hole penetrating in the vertical direction, the valve stem 33 passes through the through hole and extends into the concave cavity 381, and the valve core 34 is arranged in the concave cavity 381. When the valve core 34 is in the first position, the upper end surface of the valve core 34 abuts against the upper wall surface of the concave cavity 381. The stopper 38 can limit the excessive upward movement of the valve core 34 when the user pulls up the valve stem 33, so as to prevent the sealing member 37, the valve core 34 and other structures from being pulled out of the first valve cavity 32, thereby ensuring the reliability of use.

[0127] like Fig.12 As shown, the reset member 36 is sleeved on the valve stem 33, and the two ends of the reset member 36 in the vertical direction are respectively in contact with the sealing member 37 and the limiting member 38, and the reset member 36 is used to apply a force to the sealing member 37 in a direction away from the limiting member 38. The reset member 36 indirectly realizes the reset of the valve core 34 by applying a force to the sealing member 37, preventing the user from pulling up the valve incompletely, thereby preventing the air outlet 392 of the stir-fry valve from being not completely closed, thereby improving the safety of the stove.

[0128] The reset member 36 in this embodiment is a coil spring. In other alternative implementations, the reset member 36 may also be other reset structures that can achieve the above functions.
