Description

A commercial gas stove and cooktop suitable for cookware of different shapes Technical Field

[0001] This utility model belongs to the field of stove technology, specifically relating to a commercial gas furnace and stove that can be used with cookware of different shapes. Background Technology

[0002] In my country, where Chinese cuisine is the dominant food, hotels, canteens, and central kitchens are all equipped with commercial gas stoves for cooking Chinese food. To improve heat energy utilization, the burners of existing commercial gas stoves mainly consist of a combustion chamber that surrounds the bottom of the cookware and a burner installed in the combustion chamber. Most current combustion chambers are suitable for woks with curved bottoms or flat-bottomed pans whose bottom surface is larger than the top of the combustion chamber. As people's living standards improve and their food culture becomes increasingly diverse, ingredients and cooking methods are also becoming more varied. As a result, various cookware for frying, stir-frying, steaming, boiling, and even cooking utensils for Western cuisine have emerged, which exacerbates the contradiction between the adaptability of stoves and various cookware.

[0003] To alleviate the aforementioned contradictions, restaurants and eateries are forced to equip themselves with two or more different types of stoves to accommodate various cookware. This not only increases the investment costs for businesses but also reduces the utilization rate of each stove to some extent. Therefore, developing a stove that can accommodate a variety of different shaped cookware has become a pressing technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a commercial gas furnace and stove that can be used for cookware of different shapes, including curved pots of different sizes and flat-bottomed pans of different sizes.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: Design a commercial gas furnace that can be used for cookware of different shapes, including a furnace body that is flared from bottom to top, characterized in that: the furnace body is detachably equipped with an adjustment ring, the top of the adjustment ring is set beyond the top of the furnace body, the adjustment ring is provided with two or more inwardly extending support arms, the support arms have a first support part, and the top of the first support part is level with the top of the adjustment ring.

[0006] Furthermore, the support arm is provided with two or more first support parts arranged sequentially from the outside to the inside, and a first air passage groove is provided between two adjacent first support parts.

[0007] Furthermore, the outer wall of the adjusting ring has outward protrusions that can be supported on the inner wall of the furnace body.

[0008] Furthermore, the first support portion is a protruding post and / or a tooth tip.

[0009] Furthermore, two or more support arms are evenly distributed along the circumference of the adjustment ring.

[0010] Furthermore, a connecting ring is provided on the inner side of the adjusting ring, and the connecting ring is connected to each connecting arm.

[0011] Furthermore, the top wall of the connecting ring has two or more second support portions, which are arranged along the circumference of the connecting ring, and a second air passage groove is provided between two adjacent second support portions.

[0012] Furthermore, the top of the furnace body is provided with a first exhaust groove, the inner end of which is connected to the inner cavity of the furnace body and the outer end of which is connected to the outside.

[0013] Furthermore, the first exhaust groove is located at the rear of the furnace body, the adjusting ring can block the first exhaust groove, the top of the adjusting ring is provided with a second exhaust groove, the second exhaust groove is located in front of the first exhaust groove, the inner end of the second exhaust groove is connected to the inner cavity of the furnace body, and the outer end is connected to the outside.

[0014] This utility model also provides a stove, including a furnace chamber, characterized in that: the furnace chamber is the aforementioned commercial gas furnace chamber that can be used with cookware of different shapes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Because the furnace body is flared from bottom to top, it can be used with cookware of different sizes and curved bottoms. After installing the adjustment ring on the furnace body, it can be used with flat-bottomed pans of different sizes. Thus, the same furnace can be used with both curved pans and flat-bottomed pans, increasing the range of use of the furnace and improving its utilization rate.

[0017] 2. Since the support arm is provided with two or more first support parts arranged sequentially from the outside to the inside, and there is a first air passage groove between two adjacent first support parts, the support arm can increase the friction between the support arm and the bottom of the pan while being used with pans of different sizes, effectively preventing the pan from slipping; it can also reduce the contact area between the support arm and the bottom of the pan, allowing the hot air flow of combustion to pass through the first air passage groove, thereby enhancing the uniformity of heating of the bottom of the pan.

[0018] 3. Because the outer wall of the adjusting ring has outward protrusions, the protrusions can support the inner wall of the furnace body, so that the protrusions only contact the furnace body, greatly reducing the contact area between the two, making it easier to remove the adjusting ring and more convenient to use.

[0019] 4. Since two or more support arms are evenly distributed along the circumference of the adjustment ring, they can evenly support and contact the bottom of the pan, further promoting the uniformity of heating.

[0020] 5. Because the inner side of the adjusting ring is equipped with a connecting ring, which is connected to each connecting arm, it can enhance the stability of the distribution of each connecting arm and help extend its service life.

[0021] 6. Because the top of the furnace body is provided with a first exhaust groove, the inner end of the first exhaust groove is connected to the inner cavity of the furnace body and the outer end is connected to the outside, which can make the flue gas of combustion in the furnace smoothly discharged and promote normal combustion in the furnace.

[0022] 7. Since the first exhaust duct is located at the rear of the furnace body, when using an arc-shaped pot, the flue gas can be discharged from the rear of the pot, keeping it as far away from the cook as possible and improving the quality of their working environment; while when using the regulating ring, the flue gas and residual heat can be discharged from the sides of the pot, avoiding direct spraying onto the wall or other objects behind the pot.

[0023] 8. This utility model has an ingenious design. Through the design of the adjustment ring, the same furnace can be used for both curved pots and flat-bottomed pots, completing the cooking of Chinese and Western dishes, improving the utilization rate of the stove head, and is worth promoting and using in the industry.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] When this utility model is in working condition, the end away from the ground is defined as the top or upper end, and the end closer to the ground is defined as the lower end or bottom end; the side closer to the burning flame is defined as the inner side, and the side away from the burning flame is defined as the outer side; the side closer to the chef is defined as the front, and the side away from the chef is defined as the rear.

[0033] As shown in Figure 1, the furnace body 1 of this utility model is flared from bottom to top. The top of the furnace body 1 is provided with a first exhaust groove 2, which is located at the rear of the furnace body 1. The inner end of the first exhaust groove 2 connects to the inner cavity of the furnace body 1, and the outer end connects to the outside. When using an arc-shaped pot, it not only allows the flue gas after combustion to be smoothly discharged, promoting normal combustion in the furnace, but also allows the flue gas to be discharged from the rear of the pot, keeping the chef as far away from the discharged flue gas as possible, thus improving the quality of their working environment. As shown in Figures 3 and 4, an adjusting ring 3 is detachably installed on the furnace body 1. The top of the adjusting ring 3 extends beyond the top of the furnace body 1, as shown in Figure 2. The adjusting ring 3 can block the first exhaust groove 2. The top of the adjusting ring 3 is provided with a second exhaust groove 5, which is located in front of the first exhaust groove 2. The inner end of the second exhaust groove 5 connects to the inner cavity of the furnace body 1, and the outer end connects to the outside. Thus, when the adjusting ring 3 is not used, the furnace is suitable for arc-shaped pots, and when the adjusting ring 3 is used, it is suitable for flat-bottomed pots. When using the regulating ring 3, the smoke and residual heat are discharged from both sides of the pot, preventing direct spraying onto the wall or other objects behind the pot. The regulating ring 3 has six inwardly extending support arms 4, which are evenly distributed around the circumference of the regulating ring 3. Each support arm 4 has a first support part 7, the top of which is flush with the top of the regulating ring 3. Each support arm 4 has two or more first support parts 7 arranged sequentially from the outside to the inside, and a first air passage groove 8 between two adjacent first support parts 7. This allows the support arm 4 to increase the friction between itself and the bottom of the pot when used with different sized flat-bottomed pots, effectively preventing the pot from slipping; it also reduces the contact area between the support arm 4 and the bottom of the pot, allowing the hot air from combustion to pass through the first air passage groove 8, thus enhancing the uniformity of heating of the bottom of the pot.

[0034] To facilitate the removal of the adjusting ring 3, as shown in Figures 5 and 6, this invention also provides an outwardly protruding protrusion 11 on the outer wall of the adjusting ring 3. The protrusion 11 can support the inner wall of the furnace body 1. In this way, the protrusion 11 reduces the contact area between the adjusting ring 3 and the furnace body 1, reducing the friction between the two, making it easier to remove the adjusting ring 3 and more convenient to use. The specific shape of the protrusion 11 can be strip-shaped or discontinuous, both of which can serve to reduce the contact area.

[0035] As shown in Figure 2, this invention also includes a connecting ring 6 on the inner side of the adjusting ring 3. The connecting ring 6 connects to each connecting arm, enhancing the stability of the connecting arm distribution and extending its service life. The top wall of the connecting ring 6 has two or more second support portions 9, arranged circumferentially around the connecting ring 6. A second air passage groove 10 is located between two adjacent second support portions 9. The function of the second support portions 9 and the second air passage groove 10 is the same as that of the first support portion 7 and the first air passage groove 8: providing support and preventing slippage, while also reducing the contact area between the connecting ring 6 and the bottom of the pot, allowing the hot airflow from combustion to pass through the first air passage groove 8, thus enhancing the uniformity of heating of the pot bottom. Specifically, the first support portion 7 and the second support portion 9 can be protruding pillars or toothed shapes. Toothed shapes are preferred, as this forms a serrated shape between the first support portion 7 and the first air passage groove 8, and between the second support portion 9 and the second air passage groove 10, increasing the airflow and making the cookware heat more evenly.

[0036] This utility model also applies the above-mentioned furnace chamber to a gas stove to form a gas stove that can be used with cookware of different shapes.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model are not permitted.
