Description

Technical Field

[0001] The present application relates to the technical field of electrical appliances, and more specifically, to a thermal device, a cooking appliance and a heating appliance. Background Art

[0002] A pellet stove is a device that uses biomass pellets as fuel to release heat for heating. The heating process requires the delivery of biomass pellets and air to the fire cup so that the biomass pellets and air can be mixed and burned, thereby achieving the heating effect. At present, the fire cup used in the pellet stove is a can-shaped structure with a closed bottom and an open top. A large hole is opened on one side of the fire cup to connect with the feed pipe, and the pellets are fed into the fire cup from this hole. However, when the pellets burn in the fire cup, the flame will enter the feed pipe through the hole in the feed pipe and ignite the pellets in the feed pipe, resulting in the problem of smoke return and flashback; in addition, the large flat surface at the bottom is not conducive to the aggregation and combustion of pellets. Summary of the invention

[0003] Embodiments of the present application provide a thermal device, a cooking appliance, and a heating appliance.

[0004] The thermal equipment of the embodiment of the present application includes a combustion cup, a feed assembly and a smoke shield. The combustion cup includes a combustion chamber and a feed port. The feed port is arranged on the side plate of the combustion cup and connected to the combustion chamber. The feed assembly is used to transport biomass particles to the combustion cup through the feed port. The smoke shield is connected to the side plate of the combustion cup and is located on the upper side of the feed port. The smoke shield is used to block the upper half space of the feed port.

[0005] In the thermal device of the embodiment of the present application, the thermal device includes a combustion cup, a feed assembly and a smoke shield. The combustion cup includes a feed port arranged on the side plate of the combustion cup. The feed assembly is connected to the combustion cup and used to transport biomass particles to the combustion cup through the feed port. The smoke shield is connected to the side plate of the combustion cup and is located on the upper side of the feed port. The smoke shield is used to block the upper half space of the feed port. In this way, the biomass particles burn in the combustion cup to release heat energy, and the smoke generated can be discharged upward to the environment. The smoke shield can block the smoke and prevent the rising smoke and flame from entering the feed assembly, thereby preventing the problem of smoke backfire without affecting the normal entry of the biomass particles into the combustion cup.

[0006] In some embodiments, the smoke shield includes a connecting portion and a protruding portion, wherein the connecting portion is connected to the side plate of the combustion cup and is located on the upper side of the feed port, and the protruding portion protrudes obliquely downward from the connecting portion to the side away from the feed port. In this way, the connecting portion can be connected to the combustion cup and the protruding portion can be extended toward the end away from the feed port, and the protruding portion can be arranged obliquely downward to cover the upper half of the feed port, so that the smoke dust is blocked while ensuring that the feed port can feed downward, so as to prevent the smoke dust generated when the biomass particles are burned in the combustion chamber from flowing back to the feed assembly through the feed port.

[0007] In some embodiments, the distance between the lower edge of the extension and the lower edge of the feed port is greater than 10 mm. Thus, the distance between the lower edge of the extension and the lower edge of the feed port is greater than 10 mm to ensure that the feed assembly can transport the biomass particles to the combustion chamber through the feed port, and to avoid the distance between the extension and the lower edge of the feed port being too small, resulting in the biomass particles being blocked at the feed port.

[0008] In some embodiments, the thermal device further comprises a first guide plate, the first guide plate is tilted so that the two ends of the first guide plate are respectively connected to the bottom plate and the side plate of the combustion cup, the first guide plate is arranged directly below the feed port, and the angle between the first guide plate and the bottom plate of the combustion cup is 30-80 degrees. In this way, the first guide plate can be arranged directly below the feed port, and after the biomass particles enter the combustion chamber through the feed port, the biomass particles can be gathered by the first guide plate to ensure that the heat is concentrated and fully burned.

[0009] In some embodiments, the thermal device further comprises a second guide plate, which is arranged opposite to the first guide plate. Thus, the second guide plate is arranged on the opposite side of the first guide plate, and the second guide plate and the first guide plate can cooperate to gather the biomass particles, and the biomass particles can slide along the first guide plate and the second guide plate to the bottom plate of the combustion cup respectively after passing through the feed port, and the two guide plates can occupy the space of the bottom plate, so that the biomass particles can be more concentrated together, ensuring the intense combustion and improving the efficiency of heat generation.

[0010] In some embodiments, the first guide plate and the combustion cup bottom plate form a ventilation space, the first guide plate includes at least one through hole, the combustion cup bottom plate is formed with an air guide hole, the air guide hole connects the ventilation space with the outside, and the air guide hole connects the ventilation space with the combustion chamber. In this way, the airflow can enter the combustion chamber along the air guide hole, the ventilation space and the through hole, ensuring that the combustion chamber can have enough oxygen to mix with the biomass particles for combustion, so that the combustion is more fully controllable.

[0011] In some embodiments, the thermal device further comprises a blower and an air duct, wherein the blower and the combustion cup are arranged in the air duct, and the blower is used to generate airflow in the air duct, and the air guide hole connects the ventilation space and the air duct. In this way, the blower can generate airflow in the air duct, and the airflow can enter the combustion chamber along the air guide hole, the ventilation space and the through hole, so as to ensure that the combustion chamber can have enough oxygen to mix with the biomass particles for combustion, so that the combustion is more fully controllable.

[0012] In some embodiments, the feed assembly includes a feed pipe group, the feed pipe group is arranged in the air duct and partially extends into the feed port, and a gap for air intake is formed between the feed pipe group and the combustion cup. In this way, the feed pipe group can be connected to the feed port and a certain feeding speed can be ensured, so that the feed pipe group and the blower can cooperate to control the biomass particles and oxygen entering the combustion chamber, ensuring that the biomass particles and oxygen can be fully mixed and burned.

[0013] In some embodiments, one end of the feed pipe group near the feed port includes an air supply hole, and the air supply hole communicates with the air duct pipe and the inside of the feed pipe group. In this way, the feed pipe group can simultaneously introduce the airflow in the air duct pipe into the inside of the feed pipe group while conveying the biomass particles, so that the airflow enters the combustion chamber through the inside of the feed pipe group and the feed port, ensuring the full combustion of the biomass particles in the combustion chamber, and at the same time, the inside of the feed pipe group can have a certain air pressure on the combustion chamber to avoid the backflow of smoke generated by the combustion.

[0014] In some embodiments, the diameter of the through hole is greater than or equal to 2 mm. Thus, the through hole diameter is set to be greater than or equal to 2 mm so that the airflow in the ventilation space can pass quickly, ensuring that there is enough oxygen in the combustion chamber to cooperate with the combustion of the biomass particles.

[0031] See also Figure 1 , Figure 2 and Figure 3 The thermal device 100 of the embodiment of the present application includes a combustion cup 10, a feed assembly 20 and a smoke shield 30. The combustion cup 10 includes a combustion chamber 11 and a feed port 12. The feed port 12 is arranged on the side plate of the combustion cup 10 and is connected to the combustion chamber 11. The feed assembly 20 is used to transport biomass particles to the combustion cup 10 through the feed port 12. The smoke shield 30 is connected to the side plate of the combustion cup 10 and is located on the upper side of the feed port 12. The smoke shield 30 is used to block the upper half space of the feed port 12.

[0032] In the thermal device 100 of the embodiment of the present application, the thermal device 100 includes a combustion cup 10, a feed assembly 20 and a smoke shield 30. The combustion cup 10 includes a feed port 12 arranged on the side plate of the combustion cup 10. The feed assembly 20 is connected to the combustion cup 10 and is used to transport biomass particles to the combustion cup 10 through the feed port 12. The smoke shield 30 is connected to the side plate of the combustion cup 10 and is located on the upper side of the feed port 12. The smoke shield 30 is used to block the upper half space of the feed port 12. In this way, the biomass particles burn in the combustion cup 10 to release heat energy, and the smoke generated can be discharged upward to the environment. The smoke shield 30 can block the smoke and prevent the rising smoke and flame from entering the feed assembly 20, thereby preventing the problem of smoke backfire without affecting the normal entry of the biomass particles into the combustion cup 10.

[0033] Specifically, the thermal device 100 of the present application can transport biomass particles to the combustion chamber 11 to mix with oxygen for combustion, so as to generate sufficient heat for production and life. That is to say, an open flame will be generated in the combustion cup 10, and smoke will be generated at the same time. Most of the smoke will rise and be discharged from the top of the combustion cup 10, and a small part of the smoke can return to the feed assembly 20 through the feed port 12, resulting in the problem of smoke return and flashback.

[0034] The thermal device 100 of the embodiment of the present application can be provided with a smoke baffle 30 on the upper side of the feed port 12. The smoke baffle 30 can block the upper half space of the feed port 12 and expose the lower half space. On the one hand, it can ensure that the feed assembly 20 can normally deliver the biomass particles into the combustion chamber 11 through the feed port 12. On the other hand, the smoke dust has a high temperature and rises upward. The smoke baffle 30 located on the upper side of the feed port 12 can block the smoke dust from entering, ensuring that the smoke dust can be discharged from the top of the combustion cup 10 into the air.

[0035] See also Figure 2 and Figure 3 In some embodiments, the smoke baffle 30 includes a connecting portion 31 and an extending portion 32. The connecting portion 31 is connected to the side panel of the combustion cup 10 and is located on the upper side of the feed port 12. The extending portion 32 extends obliquely downward from the connecting portion 31 to a side away from the feed port 12.

[0036] In this way, the connecting portion 31 can be connected to the combustion cup 10 and extend the extension portion 32 toward the end away from the feed port 12. The extension portion 32 can be set obliquely downward to cover the upper half of the feed port 12. In this way, while ensuring that the feed port 12 can feed downward, it blocks smoke and prevents the smoke generated by the combustion of biomass particles in the combustion chamber 11 from flowing back to the feed assembly 20 through the feed port 12.

[0037] Specifically, the connecting portion 31 can be arranged horizontally, and while being connected to the upper side of the feed port 12, the extending portion 32 can be kept at a certain distance from the feed port 12, so as to avoid the problem that the extending portion 32 is too close to the feed port 12 and blocks the biomass particles. At the same time, the extending portion 32 can extend obliquely downward from the connecting portion 31 in a direction away from the feed port 12, so as to expand the space for the biomass particles to enter, and avoid the smoke baffle 30 hindering the feeding efficiency of the biomass particles.

[0038] See also Figure 3 In some embodiments, the distance between the lower edge of the extension portion 32 and the lower edge of the feed port 12 is greater than 10 mm.

[0039] In this way, the distance between the lower edge of the extension portion 32 and the lower edge of the feed port 12 is greater than 10 mm to ensure that the feed assembly 20 can transport the biomass particles to the combustion chamber 11 through the feed port 12, and to avoid the distance between the extension portion 32 and the lower edge of the feed port 12 being too small, causing the biomass particles to be blocked at the feed port 12.

[0040] Specifically, the left and right sides of the extension portion 32 can be connected to the side walls of the combustion cup 10, and cooperate with the connecting portion 31 to form a semi-closed feeding space. The biomass particles enter the feeding space after passing through the feed port 12, and then enter the combustion chamber 11 through the space between the lower edge of the extension portion 32 and the lower edge of the feed port 12 for combustion reaction.

[0041] In the embodiment of the present application, the specific type and size of the biomass particles are not limited, and the biomass particles only need to have good combustion and heat generation performance and a size less than 10 mm to meet different needs. In one example, the size of the biomass particles is 5 mm, and they can enter the combustion chamber 11 through the position between the lower edge of the extension 32 and the lower edge of the feed port 12 to ensure the normal combustion reaction.

[0042] See also Figure 2 and Figure 3 In some embodiments, the thermal device 100 further includes a first guide plate 40, which is tilted so that the two ends of the first guide plate 40 are respectively connected to the bottom plate and the side plate of the combustion cup 10, and the first guide plate 40 is arranged directly below the feed port 12, and the angle between the first guide plate 40 and the bottom plate of the combustion cup 10 is 30-80 degrees. For example, the angle between the first guide plate 40 and the bottom plate of the combustion cup 10 can be 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, or 80 degrees.

[0043] In this way, the first guide plate 40 can be disposed directly below the feed port 12. After the biomass particles enter the combustion chamber 11 through the feed port 12, the biomass particles can be gathered by the first guide plate 40 to ensure that the heat is concentrated and fully burned.

[0044] Specifically, the first guide plate 40 can be tilted in the combustion cup 10, and the two ends of the first guide plate 40 are respectively connected to the bottom plate and the side plate of the combustion cup 10, so as to ensure that the biomass particles can be gathered at a position on the bottom plate when entering the combustion chamber 11. It can be understood that the feed port 12 is a distance away from the bottom plate of the combustion cup 10, and when the feed assembly 20 transports the biomass particles into the combustion cup 10, the biomass particles can fall and scatter on the bottom plate. The first guide plate 40 can assist in gathering the biomass particles in the middle position of the bottom plate. The first guide plate 40 is arranged directly below the feed port 12. Some of the biomass particles can fall directly to the middle position of the bottom plate, while some of the biomass particles can slide along the first guide plate 40 to the middle position of the bottom plate, so that the biomass particles can be gathered together, ensuring the gathering and continuation of the combustion primer and better promoting continuous combustion.

[0045] See also Figure 2 and Figure 3 In some embodiments, the thermal device 100 further includes a second guide plate 50 , and the second guide plate 50 is disposed opposite to the first guide plate 40 .

[0046] In this way, the second guide plate 50 is arranged on the opposite side of the first guide plate 40. The second guide plate 50 and the first guide plate 40 can cooperate to gather the biomass particles. After passing through the feed port 12, the biomass particles can slide along the first guide plate 40 and the second guide plate 50 to the bottom plate of the combustion cup 10 respectively. The two guide plates can occupy the space of the bottom plate, so that the biomass particles can be more concentrated together, ensuring the intense combustion and improving the efficiency of heat generation.

[0047] Specifically, a second guide plate 50 is provided on the opposite side of the first guide plate 40, and the angle between the second guide plate 50 and the bottom plate of the combustion cup 10 is 30-80 degrees. In this way, on the one hand, the second guide plate 50 can be set at the same angle as the first guide plate 40, and the second guide plate 50 can be prevented from sliding to the middle of the bottom plate of the combustion cup 10. The first guide plate 40 and the second guide plate 50 can cooperate to gather the biomass particles together, avoiding the large bottom surface that is not conducive to the gathering and combustion of the biomass particles. The two guide plates cooperate to form a conical bottom structure, so that the particles and other materials can gather in the middle of the fire cup, making the combustion more centered and stable.

[0048] See also Figure 2 and Figure 3 In some embodiments, the first guide plate 40 and the bottom plate of the combustion cup 10 form a ventilation space 41, the first guide plate 40 includes at least one through hole 42, the bottom plate of the combustion cup 10 is formed with an air guide hole 13, the air guide hole 13 connects the ventilation space 41 and the outside, and the air guide hole 13 connects the ventilation space 41 and the combustion chamber 11.

[0049] In this way, the airflow can enter the combustion chamber 11 along the air guide holes 13, the ventilation space 41 and the through holes 42, ensuring that the combustion chamber 11 can have enough oxygen to mix with the biomass particles for combustion, making the combustion more sufficient and controllable.

[0050] Specifically, the second guide plate 50 can also form the same structure as the first guide plate 40, and the second guide plate 50 also cooperates with the bottom plate of the combustion cup 10 to form a ventilation space 41, so that fresh air can enter the combustion chamber 11 through the air guide hole 13, the connecting space and the through hole 42 in sequence, so that the biomass particles can be mixed with oxygen in the air and burned. Carbon dioxide and smoke produced by combustion can be discharged upward from the combustion chamber 11, and at the same time, the airflow can enter the combustion chamber 11 through the through hole 42 to supplement oxygen, ensuring that there is enough oxygen to help the combustion of biomass particles, so that the combustion process is continuous and controllable.

[0051] See also Figure 2 and Figure 3 In some embodiments, the diameter of the through hole 42 is greater than or equal to 2 mm. For example, the diameter of the through hole 42 can be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, or 6 mm.

[0052] Thus, the diameter of the through hole 42 is set to be greater than or equal to 2 mm, so that the airflow in the ventilation space 41 can pass quickly, ensuring that there is enough oxygen in the combustion chamber 11 to facilitate the combustion of the biomass particles.

[0053] See also Figure 1 and Figure 2 In some embodiments, the thermal device 100 also includes a blower 60 and an air duct pipe 70. The blower 60 and the combustion cup 10 are arranged in the air duct pipe 70. The blower 60 is used to generate airflow in the air duct pipe 70. The air guide hole 13 connects the ventilation space 41 and the air duct pipe 70.

[0054] In this way, the blower 60 can generate airflow in the air duct 70, and the airflow can enter the combustion chamber 11 along the air guide holes 13, the ventilation space 41 and the through holes 42, ensuring that the combustion chamber 11 can have enough oxygen to mix with the biomass particles for combustion, making the combustion more sufficient and controllable.

[0055] For further information, see Figure 1 and Figure 2 In some embodiments, the feed assembly 20 includes a feed pipe group 21, which is disposed in the air duct 70 and partially extends into the feed port 12, and a gap for air intake is formed between the feed pipe group 21 and the combustion cup 10.

[0056] In this way, the feed pipe group 21 can be connected to the feed port 12 and ensure a certain feeding speed. In this way, the feed pipe group 21 and the blower 60 can cooperate to control the biomass particles and oxygen entering the combustion chamber 11 to ensure that the biomass particles and oxygen can be fully mixed and burned.

[0057] Specifically, the thermal device 100 may further include a feed motor 80, and the feed assembly 20 may further include a feed screw 22 disposed in the feed pipe group 21. The feed motor 80 is connected to the feed screw 22 and provides kinetic energy to drive the feed screw 22 to rotate in the feed pipe group 21. The two ends of the feed pipe group 21 are respectively a silo and a combustion cup 10. The rotation of the feed screw 22 can transport the biomass particles in the silo to the feed port 12. At the same time, the blower 60 operates to generate airflow in the air duct pipe 70, and the airflow can flow into the combustion cup 10 along the air duct of the air duct pipe 70. In this way, the feed motor 80 can cooperate with the blower 60 to adjust the ratio of biomass particles and airflow entering the combustion chamber 11 to control the combustion mode and efficiency. It can be understood that the faster the feed screw 22 rotates, the faster the feed, the greater the air volume of the blower 60, the greater the firepower and the higher the temperature.

[0058] See also Figure 2 In some embodiments, one end of the feed pipe group 21 close to the feed port 12 includes an air supply hole 211 , and the air supply hole 211 connects the air duct pipe 70 and the interior of the feed pipe group 21 .

[0059] In this way, the feed pipe group 21 can simultaneously introduce the airflow in the air duct 70 into the feed pipe group 21 while conveying the biomass particles, so that the airflow enters the combustion chamber 11 through the feed pipe group 21 and the feed port, thereby ensuring the full combustion of the biomass particles in the combustion chamber 11. At the same time, the feed pipe group 21 can have a certain air pressure on the combustion chamber 11 to avoid the backflow of smoke generated by the combustion.

[0060] Specifically, the feed pipe group and the combustion cup 10 can be nested in the air duct pipe 70, and a plurality of blast holes 14 can be set on the side wall of the combustion cup 10. The blast holes 14 directly connect the air duct pipe 70 and the combustion chamber 11 to ensure that enough air enters the combustion chamber 11 to mix and burn with the biomass particles. In one example, two rows of blast holes 14 can be set on the side wall of the combustion cup 10, and the lower row of blast holes 14 can be lower than the feed port 12 to ensure that the air can contact the biomass particles the moment it enters. The upper row of blast holes 14 is higher than the lower edge of the extension 32 to prevent the biomass particles from falling out of the blast holes 14.

[0061] Furthermore, the air supply hole 211 on the feed pipe group 21 can ensure the air pressure inside the feed pipe group 21, so that when the blower 60 is started, the air flow can enter the combustion chamber 11 through the air supply hole 211, so that the inside of the feed pipe group 21 has a certain air pressure on the combustion chamber 11, thereby preventing the smoke generated by the combustion from flowing back. The extension part 32 extends obliquely downward relative to the connecting part 31, and the inclined structure of the extension part 32 cooperates with the air supply hole 211 to guide the air flow into the lower part, ensuring that the wind pressure at the lower part is greater than the wind pressure at the bottom of the combustion chamber 11, and effectively preventing smoke and flames from entering the feed pipe group 21 from the lower opening.

The feed assembly 20 is connected to the combustion cup 10 and is used to transport biomass particles to the combustion cup 10 through the feed port 12. The smoke baffle 30 is connected to the side plate of the combustion cup 10 and is located on the upper side of the feed port 12. The smoke baffle 30 is used to block the upper half space of the feed port 12. In this way, the biomass particles burn in the combustion cup 10 to release heat energy, and the smoke generated can be discharged upward to the environment. The smoke baffle 30 can block the smoke and prevent the rising smoke and flame from entering the feed assembly 20, thereby preventing the problem of smoke backfire without affecting the normal entry of the biomass particles into the combustion cup 10.
