Description

Technical Field

[0001] The present invention relates to the field of cooking appliances, and particularly to a gas stove. Background Art

[0002] In gas stoves, a liquid receiving tray is generally provided to receive the overflow liquid during cooking and prevent the overflow liquid from entering the interior of the chassis of the gas stove. However, there is usually a gap between the liquid receiving tray and the cooking appliance panel of the gas stove. Therefore, when there is a large amount of overflow liquid, the liquid receiving tray is filled with the overflow liquid, and the overflow liquid will enter the interior of the chassis through the gap. To address the problem that the overflow liquid enters the interior of the chassis through the gap of the external liquid receiving tray during use, adding a rubber pad or silicone glue is generally adopted in the prior art. The rubber pad and the silicone glue achieve the purpose from the perspective of preventing the overflow liquid from entering, and the high-temperature resistance and durability of rubber pads and silicone glues of different materials are limited. For example, the silicone glue remains effective for a long time under the condition of 200°C, and is prone to failure in an environment above 200°C. When the gas stove is in use, the temperature of the liquid receiving tray is mostly above 300°C, and the rubber pad and the silicone glue are prone to failure. Once the rubber pad and the silicone glue age and fail, the overflow liquid will enter the interior of the chassis through the gap of the liquid receiving tray, resulting in liquid accumulation inside the chassis. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect that the overflow liquid of the liquid receiving tray in the prior art enters the interior of the chassis, and provide a gas stove.

[0004] The present invention solves the above technical problem through the following technical solutions:

[0005] A gas stove, the gas stove includes a cooking appliance panel, a first liquid receiving tray and a burner, the gas stove further includes a second liquid receiving tray, the second liquid receiving tray is disposed close to the base of the burner and is located below the first liquid receiving tray and the cooking appliance panel, the second liquid receiving tray has a downwardly concave recess, the first liquid receiving tray has an overflow channel communicating the liquid storage space of the first liquid receiving tray and the recess, and at least a part of the recess is vertically close to the ejector pipe of the burner and is located above the ejector pipe.

[0006] In this technical solution, by providing a second liquid receiving tray with a downwardly concave recess below the first liquid receiving tray and providing an overflow channel on the first liquid receiving tray, the overflow liquid can flow through the overflow channel to the recess of the second liquid receiving tray, and the recess is used to store the overflow liquid, thereby increasing the liquid holding volume of the liquid receiving tray. At the same time, since the second liquid receiving tray is located below the cooking appliance panel, it is ensured that from the perspective of the tabletop, the liquid holding structure is the same as the current structure, without affecting the user's usage habits.

[0007] Meanwhile, by arranging the recess to be at least partially downward close to the ejector pipe in the vertical direction, after the heat of the burner raises the temperature of the second liquid receiving tray, the second liquid receiving tray can also function to radiatively transfer heat to the ejector pipe, increase the temperature inside the ejector pipe section, preheat the gas and air inside the ejector pipe, and thus improve the combustion efficiency.

[0008] Preferably, the second liquid receiving tray is annular in shape and is arranged around the base of the burner.

[0009] In this technical solution, by arranging the recess to surround the burner, the liquid holding volume of the recess can be increased.

[0010] Preferably, the radial width of the part of the recess close to the ejector pipe centered on the axis of the burner is greater than the radial width of the part of the recess far from the ejector pipe.

[0011] Preferably, the projection of the recess in the vertical direction covers at least half of the projection of the pipe section of the ejector pipe in the vertical direction.

[0012] In this technical solution, by setting the radial width of the side of the recess close to the ejector pipe to be greater than the radial width of the side of the recess far from the ejector pipe, that is to say, the part of the recess close to the ejector pipe has a larger coverage range of the pipe section of the ejector pipe, enhancing the radiative heat transfer.

[0013] Meanwhile, by arranging the projection of the recess in the vertical direction to cover at least half of the projection of the pipe section of the ejector pipe in the vertical direction, it is ensured that the part of the recess close to the ejector pipe has a larger coverage range of the pipe section of the ejector pipe, enhancing the radiative heat transfer.

[0014] Preferably, the number of burners is two, distributed on both sides of the cooktop panel. The second liquid receiving tray includes a middle plane and two recesses. The two recesses are respectively arranged corresponding to the two burners. The middle plane connects the two recesses, and the upper surface of the middle plane abuts against the lower surface of the cooktop panel.

[0015] In this technical solution, by arranging two recesses, it is adapted to a gas stove with double burners.

[0016] Meanwhile, by arranging the upper surface of the middle plane connecting the two recesses to abut against the lower surface of the cooktop panel, there is no need to use high-temperature glue to fix the cooktop panel to the second liquid receiving tray, making the heat dissipation effect of the cooktop panel better.

[0017] Preferably, the gas stove further includes a base gasket, which has elasticity and is disposed between the upper surface of the base of the burner and the lower surface of the second liquid receiving tray. The height difference from the upper surface of the base gasket to the lower surface of the cooktop panel is greater than the height difference from the lower surface of the second liquid receiving tray to the upper surface of the middle plane.

[0018] In this technical solution, by providing the base gasket, it is ensured that the middle plane can be in contact with the panel.

[0019] Preferably, the base gasket has a plurality of buffer protrusions, and the plurality of buffer protrusions are evenly spaced along the circumferential direction of the base gasket.

[0020] In this technical solution, by providing the buffer protrusions spaced on the base gasket, the elasticity of the base gasket can be enhanced, and further ensure that the middle plane can be in contact with the panel.

[0021] Preferably, the first liquid receiving tray has a through hole, and the through hole communicates the liquid storage space of the first liquid receiving tray and the recessed portion to form the overflow channel.

[0022] In this technical solution, the overflow channel is formed by opening a through hole in the first liquid receiving tray, and the structure is simpler and more reliable.

[0023] Preferably, a first protrusion is provided around the circumferential side of the recessed portion, and the first protrusion protrudes upward relative to the recessed portion. The top of the first protrusion is in contact with the lower surface of the cooktop panel.

[0024] In this technical solution, by providing the first protrusion in contact with the cooktop panel, on the one hand, it prevents the overflow liquid from flowing out of the recessed portion into the inside of the chassis. On the other hand, after the first protrusion is in contact with the cooktop panel, a closed space is formed above the recessed portion of the second liquid receiving tray, which is conducive to the accumulation of hot air, reduces the heat loss of the gas in the burner base and the base channel, increases the gas temperature, and thus improves the thermal efficiency.

[0025] Preferably, the cooktop panel has a burner installation hole, and a second protrusion is provided on one side of the second liquid receiving tray away from the ejector pipe. The second protrusion protrudes upward relative to the recessed portion, and the outer surface of the second protrusion is in contact with the hole wall of the burner installation hole.

[0026] In this technical solution, by providing the second protrusion in contact with the hole wall of the burner installation hole, the second liquid receiving tray can be used to limit the hole wall of the burner installation hole, preventing the panel from moving horizontally during transportation or other harsh conditions.

[0027] Preferably, the second liquid receiving tray is detachably connected to the base of the burner.

[0028] In this technical solution, by setting the second liquid receiving tray to be detachably connected to the base of the burner, the second liquid receiving tray can be removed for cleaning, making the cleaning more convenient.

[0029] The positive and progressive effects of the present invention are as follows: by providing a second liquid receiving tray with a downwardly concave recess below the first liquid receiving tray and providing an overflow channel on the first liquid receiving tray, the overflow can flow through the overflow channel to the recess, and the recess can be used to store the overflow, thereby increasing the liquid holding volume of the liquid receiving tray. At the same time, since the second liquid receiving tray is located below the cooktop panel, it is ensured that from the perspective of the countertop, the liquid holding structure is the same as the current structure, without affecting the user's usage habits.

[0030] At the same time, by setting the recess to be at least partially downwardly close to the ejector pipe in the vertical direction, after the heat of the burner raises the temperature of the second liquid receiving tray, the second liquid receiving tray can conduct radiative heat transfer to the ejector pipe, thereby increasing the air temperature in the ejector pipe section, preheating the air in the ejector pipe, and thus improving the combustion efficiency.

[0052] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments.

[0053] As Figures 1 - 4 shown, this embodiment provides a gas stove 100, which includes a stove top 1, a first liquid receiving tray 3, a burner 2 and a second liquid receiving tray 4. Among them, the number of burners 2 of a single gas stove 100 is two arranged in pairs, distributed on the left and right sides of the stove top 1, and each burner 2 is correspondingly provided with a first liquid receiving tray 3 and a second liquid receiving tray 4. Specifically, the second liquid receiving tray 4 is arranged close to the base of the burner 2 and is located below the first liquid receiving tray 3 and the stove top 1. The second liquid receiving tray 4 has a sunken part 401 that sinks downward. The first liquid receiving tray 3 has an overflow channel 301 that connects the liquid storage space of the first liquid receiving tray 3 and the sunken part 401. Part of the sunken part 401 is vertically close to the ejector pipe 21 of the burner 2 and is located above the ejector pipe 21. By arranging the second liquid receiving tray 4 with a downward sunken part 401 below the first liquid receiving tray 3 and arranging an overflow channel 301 on the first liquid receiving tray 3, the overflow liquid can flow through the overflow channel 301 to the sunken part 401 of the second liquid receiving tray 4, and the sunken part 401 is used to store the overflow liquid, thereby increasing the liquid holding volume of the liquid receiving tray. At the same time, since the second liquid receiving tray 4 is located below the stove top 1, it is ensured that from the perspective of the table top, the liquid holding structure is the same as the current structure, without affecting the user's usage habits.

[0054] At the same time, by arranging the sunken part 401 to be at least partially downward close to the ejector pipe 21 in the vertical direction, after the heat of the burner 2 raises the temperature of the second liquid receiving tray 4, the second liquid receiving tray 4 can also function as radiating heat transfer to the ejector pipe 21, increasing the temperature inside the ejector pipe 21 of the burner 2, preheating the gas and air inside the ejector pipe 21 of the burner 2, and thus improving the combustion efficiency.

[0055] Specifically in this embodiment, as Figure 1 and Figure 3As shown, the second liquid receiving tray 4 is annular in shape and is disposed around the base 22 of the burner 2. By arranging the recess 401 to surround the burner 2, the liquid holding volume of the recess 401 can be increased.

[0056] Of course, in other embodiments, the shape of the second liquid receiving tray 4 can also be "C" - shaped or other shapes, as long as it is ensured that the recess 401 of the second liquid receiving tray 4 is at least above the ejector tube 21.

[0057] In this embodiment, as Figure 1 and Figure 3 shown, the radial width of the part of the recess 401 close to the ejector tube 21 centered on the axis of the burner 2 is greater than the radial width of the part of the recess 401 far from the ejector tube 21. At the same time, the projection of the recess 401 in the vertical direction covers at least half of the projection of the pipe section of the ejector tube 21 in the vertical direction. By setting the radial width of the side of the recess 401 close to the ejector tube 21 to be greater than the radial width of the side of the recess 401 far from the ejector tube 21, and the projection of the recess 401 in the vertical direction covers at least half of the projection of the pipe section of the ejector tube 21 in the vertical direction, the part of the recess 401 close to the ejector tube 21 has a larger coverage range of the pipe section of the ejector tube 21, enhancing the radiative heat transfer.

[0058] Of course, in other embodiments, the recess 401 can also be set as an annular shape that is centrosymmetric about the axis of the burner 2, that is, the radial width of each part of the recess 401 is set to be the same along the circumferential direction of the burner 2, which will not be elaborated here.

[0059] In this embodiment, as Figures 1 - 3 shown, the number of burners 2 is two, distributed on both sides of the cooktop panel 1. The second liquid receiving tray 4 includes a middle plane 5 and two recesses 401. The two recesses 401 are respectively arranged corresponding to the two burners 2. The middle plane 5 connects the two recesses 401, and the upper surface of the middle plane 5 abuts against the lower surface of the cooktop panel 1. By providing two recesses 401, it is adapted to the gas stove 100 with a double - burner 2. Among them, by setting the upper surface of the middle plane 5 connecting the two recesses 401 to abut against the lower surface of the cooktop panel 1, there is no need to use high - temperature glue to fix the cooktop panel 1 and the second liquid receiving tray 4, making the heat dissipation effect of the cooktop panel 1 better.

[0060] Specifically, as Figure 1 and Figure 4As shown, the gas stove 100 further includes a base gasket 6. The base gasket 6 is elastic and is disposed between the upper surface of the base 22 of the burner 2 and the lower surface of the second liquid receiving tray 4. The height difference from the upper surface of the base gasket 6 to the lower surface of the cooktop panel 1 is greater than the height difference from the lower surface of the second liquid receiving tray 4 to the upper surface of the middle plane 5. By providing the base gasket 6, it is ensured that the middle plane 5 can be in contact with the panel. Specifically, in the case where the base gasket 6 has no elasticity, the height difference from the upper surface of the base gasket 6 to the lower surface of the cooktop panel 1 needs to be equal to the height difference from the lower surface of the second liquid receiving tray 4 to the upper surface of the middle plane 5 to ensure that the middle plane 5 is in contact with the panel. Considering the machining errors and installation errors of the components, by setting the base gasket 6 to be elastic and setting the height difference from the upper surface of the base gasket 6 to the lower surface of the cooktop panel 1 to be greater than the height difference from the lower surface of the second liquid receiving tray 4 to the upper surface of the middle plane 5, the elasticity of the base gasket 6 can be utilized to compensate for the machining errors and installation errors of the components, thereby ensuring that the middle plane 5 can be in contact with the panel.

[0061] Meanwhile, as Figure 4 shown, the base gasket 6 has a plurality of buffer protrusions 61, and the number of the buffer protrusions 61 can be set according to actual requirements. In this embodiment, the plurality of buffer protrusions 61 are arranged downward and are evenly spaced along the circumferential direction of the base gasket 6. By providing the buffer protrusions 61 spaced on the base gasket 6 and contacting the base 22 below the base gasket 6 through the buffer protrusions 61, the elasticity of the base gasket 6 in the up and down direction is enhanced by reducing the contact area, further ensuring that the middle plane 5 can be in contact with the panel.

[0062] In this embodiment, as Figure 1 shown, the first liquid receiving tray 3 has a through hole, and the through hole communicates with the liquid storage space of the first liquid receiving tray 3 and the recess 401 to form an overflow channel 301. By forming the overflow channel 301 by opening a through hole in the first liquid receiving tray 3, the structure is simpler and more reliable.

[0063] Specifically, the through hole is provided at the top of the liquid storage space of the first liquid receiving tray 3. When the liquid storage space of the first liquid receiving tray 3 is full of overflow liquid, the overflow liquid will flow to the second liquid receiving tray 4 through the overflow channel 301. Since the first liquid receiving tray 3 is above the second liquid receiving tray 4 and is relatively more convenient to clean, therefore, avoiding the overflow liquid from entering the second liquid receiving tray 4 when the liquid storage space of the first liquid receiving tray 3 is not full can reduce the cleaning requirement of the second liquid receiving tray 4 and make the maintenance of the gas stove 100 more convenient.

[0064] In this embodiment, as Figures 1 - 3As shown, a first convex part 41 is provided around the circumferential side of the recessed part 401. The first convex part 41 protrudes upward relative to the recessed part 401, and the top of the first convex part 41 abuts against the lower surface of the cooking appliance panel 1. By providing the first convex part 41 that abuts against the cooking appliance panel 1, on the one hand, it prevents the overflow liquid from flowing out of the recessed part 401 to the inside of the chassis 7. On the other hand, after the first convex part 41 abuts against the cooking appliance panel 1, a closed space is formed above the recessed part 401 of the second liquid receiving tray 4, which is conducive to the accumulation of hot air, reduces the heat loss of the gas in the burner 2 base and the base channel, increases the gas temperature, and thus improves the thermal efficiency.

[0065] Meanwhile, the cooking appliance panel 1 has a burner 2 mounting hole 101. A second convex part 42 is provided on the side of the second liquid receiving tray 4 away from the ejector pipe 21. The second convex part 42 protrudes upward relative to the recessed part 401. As Figure 2 shown, the outer surface of the second convex part 42 abuts against the hole wall of the burner 2 mounting hole 101. By providing the second convex part 42 that abuts against the hole wall of the burner 2 mounting hole 101, the second liquid receiving tray 4 can be used to limit the hole wall of the burner 2 mounting hole 101, preventing the panel from moving horizontally during transportation or other harsh conditions.

[0066] In this embodiment, the second liquid receiving tray 4 is detachably connected to the base of the burner 2. By setting the second liquid receiving tray 4 to be detachably connected to the base of the burner 2, the second liquid receiving tray 4 can be removed for cleaning, making the cleaning more convenient.

[0067] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that this is only for illustration. The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
