Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to a windproof gas stove. Background Art

[0002] A household gas stove generally includes a stove body and a support base arranged at the upper end of the stove body for supporting the pot, a burner is arranged inside the support base, and the lower end of the burner is connected to the air inlet pipe. In practice, the gas enters the inner cavity of the burner through the air inlet pipe, and then passes through the ventilation plate on the upper side of the burner to spray out a regular gas flow.

[0003] At present, the support frame is generally a tubular structure with many hollow parts. The multi-hollow design can not only reduce the overall weight of the support frame, but also ensure that sufficient air can be supplemented from the outside during the gas combustion process.

[0004] However, the multiple hollow designs also make it difficult for existing devices to resist high-speed airflow, especially when the gas output is small and the flame produced by the device is weak, the high-speed airflow can easily blow out the flame. In traditional cooking methods, the pot is generally placed on the support frame, and the pot completely covers the support frame. When the flame is small, the user cannot see the specific flame amplitude from above. Therefore, if the flame is blown out at this time, it is not easy for the user to find it, which is more likely to cause gas poisoning.

[0005] Therefore, we believe that there is a need for a windproof gas stove that can resist the direct blowing of high-speed airflow on the flame and can ensure the air replenishment required during the gas combustion process. Summary of the invention

[0006] In view of the deficiencies in the prior art, the utility model proposes a windproof gas stove, which has the advantages of preventing high-speed airflow from directly blowing the flame and ensuring air replenishment, thereby solving the shortcomings of the prior art devices that cannot resist airflow blowing and are prone to danger during use.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A windproof gas stove comprises a stove body, wherein a support frame is respectively arranged on the left and right sides of the upper end of the stove body, a burner is arranged on the inner side of the support frame, the support frame comprises a bottom ring which is an overall tubular structure, a mounting ring which is an overall cylindrical frustum structure is coaxially fixedly connected to the upper end of the bottom ring, a plurality of support plates are fixedly connected to the mounting ring, a plurality of baffles are circumferentially arranged on the outer end surface of the bottom ring, the upper ends of the baffles are fixedly connected to the outer side walls of the mounting ring, the inner walls of the baffles are not in contact with the outer wall of the bottom ring, a plurality of ventilation holes are circumferentially opened on the bottom ring, the plurality of ventilation holes correspond one to one to the plurality of baffles, and the projections of the baffles on the vertical plane completely cover the projections of the corresponding ventilation holes on the vertical plane.

[0009] Preferably, the projection of the lower end of each baffle on the horizontal plane is an arc-shaped structure, the curvature of the baffle is completely opposite to the curvature of the bottom ring, and the width of each ventilation hole is not greater than half of the width of the corresponding baffle.

[0010] Preferably, each of the support plates comprises an abutting section and a fixing section, wherein the abutting section is located on the inner side of the mounting ring, and the fixing section is located on the outer side of the mounting ring.

[0011] Preferably, the distance between the end surface of each baffle plate close to the fixed section and the fixed section is smaller than the distance between the end surface of the baffle plate close to the fixed section and the outer wall of the bottom ring.

[0012] Preferably, a positioning ring is sleeved on the outer side of the bottom ring, and a positioning groove is opened on the stove body for the positioning ring.

[0013] Preferably, the baffle plate and the lower end surface of the fixing section are in contact with the positioning ring, and the positioning ring is provided with a ventilation slot with an open structure at the upper end.

[0014] Preferably, the furnace head comprises an outer shell, a ventilation disk is arranged at the upper end of the outer shell, and the height of the upper end surface of the ventilation hole is smaller than the height of the lower end surface of the ventilation disk.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model realizes air circulation on both sides of the inner and outer sides of the support frame through the ventilation holes. At the same time, the device shields the ventilation holes through the baffles, which makes the external airflow enter the ventilation holes only through the gaps between the ventilation holes and the outer walls of the support frame. This utilizes the impact effect between the airflow and the support frame to ensure that the airflow entering the ventilation holes is turbulent, thereby preventing high-speed airflow from impacting the flame and causing the flame to be extinguished.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Please refer to Figure 1-3 , a windproof gas stove, consistent with the traditional device, the device also includes a stove body 1, and in order to ensure easy understanding, the device omits the bottom structure of the stove body 1 and only includes the part of the upper end of the stove body 1 that cooperates with the burner 3.

[0024] Therefore, the device is provided with a support frame 2 on both sides of the upper end of the stove body 1 to support the cooker.

[0025] Therefore, the device is provided with a burner head 3 on the inner side of each support frame 2. It should be noted that the lower end of the burner head 3 is connected to the air inlet pipe, and the interior of the burner head 3 is a hollow structure, which enables the gas to enter the inner cavity of the burner head 3 through the air inlet pipe.

[0026] In practice, the burner 3 includes an outer shell and a ventilation disk disposed on the outer shell. As shown in the figure, the disc-like structure with multiple through holes on the upper end of the burner 3 is the ventilation disk. Therefore, the air intake pipe is connected to the outer shell, and the gas entering the burner 3 through the air intake pipe is ejected through the through holes on the ventilation disk and ignited by the corresponding igniter to form continuous heat for cooking food.

[0027] Specifically, the support frame 2 includes a bottom ring 203 with a tubular structure at the lower end, and the bottom ring 203 plays a major supporting role.

[0028] The upper end of the bottom ring 203 is coaxially fixedly connected with a mounting ring 202 which is an overall cylindrical frustum structure. A plurality of support plates 201 are fixedly connected to the mounting ring 202, and the support plates 201 are used to support the bottom of the cookware, while ensuring that the contact area between the support base as a whole and the cookware is small.

[0029] It should be emphasized that, unlike the traditional structure, the present device does not have a large-scale hollow structure on the bottom ring 203 to ensure the weight of the support frame 2 and meet the ventilation conditions.

[0030] Specifically, the device is provided with a plurality of ventilation holes 6 circumferentially on the bottom ring 203 to meet ventilation conditions.

[0031] Furthermore, in order to achieve the windproof effect and prevent the high-speed airflow from directly blowing the flame and causing the flame to go out, the device is provided with a plurality of baffles 4 on the outside of the bottom ring 203, and the baffles 4 are constrained to correspond one by one with the ventilation holes 6. At this time, while the gap between the baffles 4 and the outer wall of the bottom ring 203 is used to realize the gas flow, it can prevent the high-speed airflow from directly hitting the flame through the ventilation holes 6 and causing it to go out. In practice, when the high-speed airflow enters through the gap between the baffles 4 and the outer wall of the bottom ring 203, the high-speed airflow will first hit the outer wall of the bottom ring 203, and the impact effect will turbulent the airflow to avoid direct blowing. At the same time, the flame consumes air during combustion, and the internal air pressure of the bottom ring 203 is reduced, which will actively inhale the airflow that has become turbulent due to the impact from the outside through the ventilation holes 6 to meet the demand.

[0032] Specifically, as shown in the figure, the upper end of the baffle 4 of the device also has a certain arc structure, and the arc direction of this arc structure is consistent with the arc direction of the mounting ring 202. This can ensure that the baffle 4 fits the outer wall of the mounting ring 202, and then achieve a fixed connection between the mounting ring 202 and the baffle 4 through rivets.

[0033] Furthermore, the device constrains the height of the upper end surface of the ventilation hole 6 to be smaller than the height of the lower end surface of the ventilation disk, which can further prevent the airflow from directly blowing the flame and causing the flame to be extinguished.

[0034] Furthermore, in order to ensure that the gas flow entering between the baffle 4 and the bottom ring 203 can meet the demand, the device constrains the projection of the lower end of the baffle 4 on the horizontal plane to be an arc structure, and the curvature of the baffle 4 is opposite to the curvature of the bottom ring 203. This ensures that there is a sufficient gap between the two ends of the baffle 4 and the inner wall of the bottom ring 203, and can avoid a large gap between the outer wall of the ventilation hole 6 and the baffle 4, thereby ensuring the inflow speed of external gas while further avoiding a faster flow rate of gas directly entering the ventilation hole 6.

[0035] Furthermore, the device constrains the width of the ventilation hole 6 to be no greater than half the width of the corresponding baffle 4. This is mainly to fully ensure that the external gas can collide with the outer wall of the bottom ring 203 to generate turbulent gas, thereby preventing the external gas from directly entering the ventilation hole 6.

[0036] It should be noted that the curvature of the baffle 4 is opposite to that of the bottom ring 203 and can also restrict the outside gas from contacting the outer wall of the bottom ring 203, thereby preventing the outside gas from directly entering the ventilation hole 6 by reducing the gas flow channel.

[0037] Furthermore, the present device constrains each support plate 201 to include an abutment section 2011 and a fixed section 2022, wherein the abutment section 2011 is located on the inner side of the mounting ring 202, and the fixed section 2022 is located on the outer side of the mounting ring 202. At this time, the fixed section 2022 and the baffle 4 are in the same horizontal plane, that is, the outside air must enter the gap between the baffle 4 and the bottom ring 203 through the gap between the fixed section 2022 and the baffle 4. This can fully ensure that the outside air cannot directly blow into the gap between the baffle 4 and the bottom ring 203, and the air between the baffle 4 and the bottom ring 203 must be a turbulent airflow.

[0038] Furthermore, in order to enhance versatility and reduce production costs, the device is provided with a positioning ring 5 on the outside of the bottom ring 203, and a positioning groove is opened on the stove body 1 for the positioning ring 5. This can realize the purpose of using the annular structure of the positioning ring 5 to constrain the position of the bottom ring 203, and constraining the position of the positioning ring 5 through the positioning groove. This makes the support frame 2 detachably connected to the stove body 1, ensuring versatility and providing users with more choices.

[0039] At the same time, as shown in the figure, a corresponding boss is arranged on the inner side of the positioning ring 5 for the bottom ring 203 to provide sufficient support and limit effect for the supporting ring.

[0040] At the same time, as shown in the figure, the lower end surface of the constrained fixing section 2022 of the device abuts against the positioning ring 5, which can further provide a supporting effect for the supporting frame 2 as a whole.

[0041] Furthermore, the device constrains the lower end of the baffle 4 to abut against the positioning ring 5, and the positioning ring 5 is provided with a ventilation slot 7 with an open structure at the upper end, and the ventilation slot 7 is used to realize the penetration of airflow. In practice, the amount of gas blown into the baffle 4 and the bottom ring 203 by high-speed airflow is greater than the amount of gas entering the inner side of the bottom ring 203 through the ventilation hole 6. Therefore, there must be a phenomenon of gas escape between the baffle 4 and the bottom ring 203, and the gas at this time still has a high speed. Therefore, the constraint of the ventilation slot 7 can make the gas flow rate in the ventilation slot 7 at a high state. This can use the ventilation slot 7 to disrupt the direction of the airflow between multiple baffles 4 and the bottom ring 203, and further ensure that there is only turbulent airflow between the baffle 4 and the bottom ring 203.
