Description

Technical Field

[0001] This utility model relates to a gas appliance, and more particularly to a gas appliance that combines heating and cooking functions. Background Technology

[0002] Gas appliances are now widely used in daily life, mainly divided into gas heating equipment and gas cooking equipment. Although their working principles are similar, their functions are independent and clearly defined, respectively meeting heating and cooking needs, which has led to a relatively low overall utilization rate for both.

[0003] Gas heating equipment is limited by season and time of day, only being used during the cold winter months and remaining idle for the rest of the year, resulting in a very low percentage of effective usage time. While gas cooking equipment is used more frequently, its actual usage time is also limited as it only performs cooking functions and cannot simultaneously meet heating needs. This means that users often have to invest twice the purchase cost when buying gas appliances with similar operating principles, only to receive a single-function user experience, resulting in a double waste of equipment resources and purchase costs.

[0004] Meanwhile, the independent design of functions also brings a series of derivative problems. In scenarios with limited space, such as small apartments and small shops, the two types of equipment need to occupy space separately, which reduces the user's activity space; and the two types of equipment need to be connected to the gas source separately, which not only makes the gas pipeline layout complicated, but also increases the potential risk of gas leakage and reduces the safety and convenience of use.

[0005] Therefore, how to overcome the above-mentioned defects and develop a gas appliance that combines heating and cooking functions has become an important issue that needs to be addressed by those skilled in the art. Utility Model Content

[0030] The following embodiments further illustrate the features of this utility model and other related features in detail, so as to facilitate understanding by those skilled in the art: like Figures 1 to 10 As shown, a gas appliance that combines heating and cooking functions includes a base 1, a gas stove 2 mounted on the upper surface of the base 1, a gas heating component 3 disposed inside the base 1, a heat exchange chamber 11 disposed on the right side of the base 1, the gas heating component 3 including a heat exchanger 31 fixed inside the heat exchange chamber 11, and perforated openings 12 on the front, right and rear sides of the right side of the base 1 for connecting the heat exchange chamber 11 with the external environment. The base 1 also includes a gas pipe assembly 4 for supplying gas to the gas stove 2 and the gas heating component 3, the gas pipe assembly 4 including a gas source interface 41 for connecting to a gas source to facilitate the input of gas.

[0031] The gas appliance in this case includes a base 1, a gas stove body 2, a gas heating component 3, and a gas pipe assembly 4. The gas stove body 2 is installed on the upper surface of the base 1, while the gas heating component 3 is located inside the base 1. The base 1 also has a gas pipe assembly 4 for connecting the gas stove body 2 and the gas heating component 3 to a gas source. Additionally, the right side of the base 1 has a heat exchange chamber 11 that communicates with the external environment through perforated openings 12 on the front, right, and rear sides. The heat exchanger 31 of the gas heating component 3 is fixed in the heat exchange chamber 11 to heat the ambient air.

[0032] As described above, the gas appliance in this case integrates the gas stove body 2 and the gas heating component 3 into the same base 1, providing both heating and cooking functions on a single device. Users can use the gas appliance for cooking or heating separately, or for both simultaneously, eliminating the need to purchase two separate devices, thus avoiding cost waste and significantly improving the overall utilization rate of the equipment. Furthermore, the integrated design allows the gas stove body 2 and the gas heating component 3 to share the space of the base 1, saving floor space and reducing the compression of user activity space. The gas pipeline assembly 4 unifies the connection between the gas stove body 2, the gas heating component 3, and the gas source, optimizing the space occupied by the gas pipeline while reducing the potential risk of gas leaks and improving convenience and safety.

[0033] Specifically, the gas pipe assembly 4 can be a commercially available pipe assembly that can split the gas source into two and deliver them to the gas stove body 2 and the gas heating component 3 respectively. The gas stove body 2 can also be a commercially available stove body. The specific structure will not be described in detail here.

[0034] like Figures 3 to 10 As shown, preferably, the gas heating component 3 includes a composite air duct 32 fixed inside the base 1. The composite air duct 32 includes two coaxial ventilation pipes extending out of the base 1, with the inner layer being an exhaust pipe and the outer layer being an intake pipe. The intake pipe is connected to a combustion chamber 33. The gas pipe assembly 4 is connected to the combustion chamber 33 to facilitate the input of gas into the combustion chamber 33 for combustion. The outlet of the combustion chamber 33 is connected to the heat exchanger 31. The end of the heat exchanger 31 is connected to a blower 34. The air inlet of the blower 34 is connected to the end of the heat exchanger 31, and the air outlet is connected to the exhaust pipe.

[0035] As described above, the gas heating component 3 of this invention includes a heat exchanger 31, a composite air duct 32, a combustion chamber 33, and a blower 34. The intake and exhaust pipes are integrated within the composite air duct 32 and are coaxially arranged, with the outer layer being the intake pipe and the inner layer being the exhaust pipe. The combustion chamber 33, heat exchanger 31, and blower 34 are sequentially connected between the intake and exhaust pipes. When the gas heating component 3 is working, fresh air enters the combustion chamber 33 through the air intake pipe, and gas is input into the combustion chamber 33 through the gas pipe assembly 4. The gas and air mix and burn in the combustion chamber 33 to generate heat. The high-temperature exhaust gas generated by combustion in the combustion chamber 33 enters the heat exchanger 31. The outer wall of the heat exchanger 31 is in direct contact with the external ambient air. After entering the heat exchanger 31, the high-temperature exhaust gas exchanges heat with the external ambient air through the heat exchanger 31, thereby heating the air and achieving a heating effect. At the same time, the blower 34 at the end of the heat exchanger 31 will also work to draw out the high-temperature exhaust gas in the heat exchanger 31 and discharge it through the exhaust pipe, thereby accelerating the gas flow in the gas heating component 3.

[0036] As described above, the gas heating component 3 in this case integrates the intake and exhaust pipes together in a coaxial, layered manner using the composite air duct 32. This reduces the number of openings in the wall when installing the intake and exhaust pipes, significantly reducing damage to the building and minimizing the space occupied on the wall, thereby improving the product's adaptability. Furthermore, the coaxial, layered arrangement of the intake and exhaust pipes allows the residual heat from the exhaust pipe to preheat the fresh air in the intake pipe, thus improving the thermal efficiency of the gas heating component 3.

[0037] like Figures 7 to 8 As shown, preferably, the composite air duct 32 includes a first pipe 321 and a composite air chamber 322. The first pipe 321 passes through the composite air chamber 322 vertically. The lower wall of the composite air chamber 322 is sealed and fixed to the outer wall of the first pipe 321. A second pipe 323 is provided on the upper wall of the composite air chamber 322, sleeved on the upper part of the first pipe 321 and coaxially arranged with the first pipe 321. The lower end of the second pipe 323 is connected to the composite air chamber 322. The composite air chamber 322 is also provided with a vent 3221. The lower end of the first pipe 321 is connected to the air outlet of the blower 34, that is, the first pipe 321 serves as an exhaust pipe. The vent 3221 is connected to the combustion chamber 33, that is, the composite air chamber 322 and the second pipe 323 serve as an intake pipe.

[0038] As described above, the composite air duct 32 of this invention includes a first pipe 321, a composite air chamber 322, and a second pipe 323. The first pipe 321 passes through the composite air chamber 322, and the lower wall of the composite air chamber 322 is sealed and fixed to the outer wall of the first pipe 321. The upper wall is provided with a second pipe 323 coaxially sleeved on the first pipe 321, and the lower end of the second pipe 323 is connected to the composite air chamber 322. In this way, the composite air chamber 322 and the second pipe 323 together form an outer air intake duct that wraps around the first pipe 321, while the first pipe 321 serves as an inner exhaust duct. Thus, the composite air duct 32 constructs a coaxially layered air intake and exhaust structure, which reduces the number of openings in the wall and utilizes the waste heat of the exhaust gas to preheat the incoming air.

[0039] like Figures 4 to 6 As shown, preferably, a cooling fan 5 is also fixed inside the heat exchange chamber 11. The cooling fan 5 is used to blow air onto the heat exchanger 31 so as to blow the hot air near the heat exchanger 31 into the room.

[0040] As described above, by installing a cooling fan 5 inside the heat exchange chamber 11 to actively blow air onto the heat exchanger 31, the airflow speed around the heat exchanger 31 can be accelerated, allowing the heat released by the heat exchange to be quickly and evenly diffused to the external area, thereby improving heating efficiency and uniformity and enhancing the heating effect. Simultaneously, continuous airflow circulation can also prevent heat accumulation near the heat exchanger 31, which could lead to localized overheating, allowing the heat generated by combustion to be more fully transferred to the external air, reducing heat waste.

[0041] like Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown, preferably, the heat exchanger 31 includes a plurality of heat dissipation pipes 311 distributed vertically. One end of each heat dissipation pipe 311 is connected to the combustion chamber 33, and the other end is connected to the air inlet of the blower 34. Each heat dissipation pipe 311 includes a transition section 3111 connected to the combustion chamber 33. The end of the transition section 3111 is connected to two heat dissipation sections 3112 distributed vertically. The heat dissipation sections 3112 extend horizontally and have multiple U-shaped bends to increase their length. The end of the heat dissipation section 3112 is connected to the air inlet of the blower 34. The diameter of the heat dissipation section 3112 is smaller than the diameter of the transition section 3111.

[0042] As described above, the heat exchanger 31 of this invention includes several heat dissipation pipes 311, each of which includes a transition section 3111 and a heat dissipation section 3112. The heat dissipation section 3112 has two sections, one above the other, located at the end of the transition section 3111. The diameter of the heat dissipation section 3112 is smaller than the diameter of the transition section 3111. Thus, the larger-diameter transition section 3111 directly connects to the combustion chamber 33, acting as an extension of the combustion chamber 33 to ensure complete combustion of the fuel gas. The end of the transition section 3111 is divided into two smaller-diameter pipes by the heat dissipation section 3112, thereby increasing the contact area between the heat dissipation pipe 311 and the external ambient air and improving heat exchange efficiency. Simultaneously, the heat dissipation section 3112 also has multiple U-shaped bends, which can extend the length of the heat dissipation pipe 311 within a certain space, prolonging the residence time of the high-temperature gas after combustion within the heat dissipation pipe 311 and fully releasing heat to the external environment, thereby reducing energy waste.

[0043] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, preferably, each perforated opening 12 is covered with a protective net 6. In this way, by setting the protective net 6, it can effectively prevent external debris, insects, etc. from entering the heat exchange chamber 11 and attaching to the heat exchanger 31, thereby affecting the heat exchange efficiency. It can also prevent users from accidentally touching the high-temperature heat exchanger 31 during use and being burned, thereby improving the safety of the equipment. Moreover, the protective net 6 will not affect the heat dissipation and heating effect.

[0044] like Figure 1 and Figure 10 As shown, preferably, a humidifying drawer 7 that can be pulled out from the front of the base 1 at the bottom of the heat exchange chamber 11 is provided. The opening of the humidifying drawer 7 is open and communicates with the heat exchange chamber 11. The humidifying drawer 7 is used to hold water.

[0045] As described above, by providing a removable humidifying drawer 7 for holding water at the bottom of the heat exchange chamber 11, the water held in the humidifying drawer 7 can be evaporated by the heat emitted by the heat exchanger 31 when the gas heating component 3 is working, thereby replenishing moisture to the air and simultaneously solving the dryness problem during low winter temperatures. The removable design also makes it convenient for users to add water to the humidifying drawer 7.

[0046] like Figure 12As shown, preferably, the gas heating component 3 is further provided with a guide pipe 8 in the air intake pipe. The guide pipe 8 is used to guide the water in the air intake pipe to the heat exchange chamber 11. The outlet of the guide pipe 8 is located above the humidification drawer 7. In this way, the rainwater entering through the air intake pipe and the condensate generated in the air intake pipe can flow to the humidification drawer 7 through the guide pipe 8 and be used by the gas heating component 3 for humidification. At the same time, this can also prevent the water in the air intake pipe from accumulating and entering the combustion chamber 33, which would cause the gas heating component 3 to fail.

[0047] Specifically, the inlet of the guide pipe 8 is connected to the bottom of the composite gas chamber 322.

[0048] Furthermore, the bottom of the composite air chamber 322 is provided with a settling trough 3222 located below the lower opening of the second pipe 323. The water inlet of the guide pipe 8 is connected to the settling trough 3222. In this way, by setting the settling trough 3222 below the second pipe 323 and connecting the water inlet of the guide pipe 8 to the settling trough 3222, it can be ensured that the water falling into the composite air chamber 322 from the second pipe 323 will be collected in the settling trough 3222 and eventually flow out from the guide pipe 8, instead of flowing into the combustion chamber 33 from the air vent 3221.

[0049] like Figure 1 and Figure 11 As shown, preferably, the left side of the seat 1 is also provided with a gas source receiving cavity 13 for placing a gas cylinder. The left side of the gas source receiving cavity 13 is an openable protective door 131. The gas source interface 41 extends into the gas source receiving cavity 13. The gas source receiving cavity 13 is provided with a U-shaped limiting baffle 132 for limiting the left and right position of the gas cylinder. In this way, the gas cylinder can be placed independently in the gas source receiving cavity 13, and the position of the gas cylinder is limited by the U-shaped limiting baffle 132 to prevent the gas cylinder from being exposed to the outside and accidentally being hit, affecting the safety of gas use.

[0050] like Figure 1 and Figure 11 As shown, preferably, the gas source receiving cavity 13 is open downwards, and a movable tray 133 with rollers at the bottom for supporting the gas cylinder is placed inside the gas source receiving cavity 13. The gas source receiving cavity 13 is also provided with a chain 134 for surrounding the gas cylinder to prevent it from shifting. In this way, placing the gas cylinder on the movable tray 133 can greatly reduce the labor intensity of handling when changing the gas cylinder. The gas cylinder can be easily pushed into or moved out of the gas source receiving cavity 13 by the rollers at the bottom of the movable tray 133, and the chain 134 surrounding the gas cylinder can cooperate with the U-shaped limiting baffle 132 to further prevent the gas cylinder from easily shifting with the movable tray 133 during use.

[0051] As stated above, this case protects a gas appliance that combines heating and cooking functions, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
