[0055] To better understand the above technical solution, the technical solution of the embodiment of the present application will be described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the embodiments are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0056] As Figures 1 to 5 shown, according to the first aspect of the embodiment of the present application, a heating appliance 100 is provided, including: a housing 110, a liquid storage cavity 111 is provided in the housing 110; a partition board 120, covering the housing 110, and a steam vent hole 121 is formed in the partition board 120; a heating element 130, arranged in the liquid storage cavity 111; an energy-gathering ring 140, communicating with the liquid storage cavity 111, a heating cavity is formed in the energy-gathering ring 140, the heating element 130 is inserted into the heating cavity, the energy-gathering ring 140 is provided with a liquid inlet 142 and an exhaust hole 141, the liquid storage cavity 111 communicates with the heating cavity through the liquid inlet 142, and the exhaust hole 141 communicates with the steam vent hole 121; wherein, the heating element 130 divides the heating cavity into a first heating part and a second heating part, and the heating element 130 is used to heat the liquid flowing into the first heating part to form steam, and during the process that the steam is transported from the first heating part to the exhaust hole 141 through the second heating part, the heating element 130 continuously heats the steam.

[0057] It can be understood that the heating appliance 100 provided in the embodiments of the present application is provided with a housing 110, a partition 120, a heating element 130, and a heat collecting ring 140. Among them, a liquid storage cavity 111 can be arranged in the housing 110 for storing the liquid to be heated. The partition 120 can cover the housing 110, and the partition 120 can be provided with a steam passing hole 121. The heating element 130 is arranged in the liquid storage cavity 111. The liquid in the liquid storage cavity 111 can be heated to form steam by the heating element 130, and the steam can be transported to the external environment through the steam passing hole 121 to heat the object to be heated. The heat collecting ring 140 communicates with the liquid storage cavity 111, and a heating cavity is formed inside the heat collecting ring 140. The heating element 130 can be inserted into the heating cavity. The heat collecting ring 140 can be formed with a liquid inlet 142 and an exhaust hole 141. Among them, the liquid inlet 142 communicates with the liquid storage cavity 111, and the liquid in the liquid storage cavity 111 can be transported to the heating cavity through the liquid inlet 142. The exhaust hole 141 can communicate with the steam passing hole 121. The heating element 130 heats the liquid in the heating cavity, and the generated steam can be transported to the steam passing hole 121 through the exhaust hole 141. Further, the heating element 130 can divide the heating cavity into a first heating part and a second heating part. Among them, the liquid in the liquid storage cavity 111 can be transported to the first heating part through the liquid inlet 142 for heating to form steam. The steam flows from the first heating part to the second heating part, and then is transported from the second heating part to the exhaust hole 141. During the transportation of the steam, the steam is continuously heated by the heating element 130 to further increase the steam temperature, generate high-temperature steam, thereby increasing the heating temperature of the heating appliance 100, improving the heating efficiency, and improving the user experience.

[0058] It should be noted that the liquid inlet 142 can be a notch formed at the bottom end of the outer wall of the heat collecting ring 140 to ensure that the liquid in the liquid storage cavity 111 can enter the first heating part to be heated by the heating element 130 even when the liquid in the liquid storage cavity 111 is less. And when the liquid in the liquid storage cavity 111 reaches the highest liquid level, the liquid is only located in the first heating part to ensure that the steam generated after the liquid is heated can enter the second heating part, and the steam flowing through the second heating part is further heated by the heating element 130. For example, when the liquid is water, the temperature of the steam formed after being heated by the first heating part is 100 °C. After the steam is heated by the second heating part, the temperature can exceed 100 °C. Thereby increasing the heating temperature of the heating appliance 100.

[0059] It should be noted that the heating appliance 100 can act on the pot body 210 to perform heat exchange with the ingredients through steam to heat the ingredients. By increasing the steam temperature, ingredients such as meat and grains with a longer cooking time can be quickly cooked, the cooking time can be shortened, and the loss of nutritional components of the ingredients can be reduced, improving the user experience.

[0060] It should be noted that the heating cavity of the energy-gathering ring 140 is an open structure, which is convenient for sleeving the heating element 130 and improves the assembly efficiency. Considering the usage scenario of the heating appliance 100, the liquid added to the liquid storage cavity 111 is usually tap water. When the tap water evaporates, scale will be generated. The open structure is convenient for users to clean the scale remaining in the heating cavity, avoiding scale accumulation and blocking the pipeline, which affects the liquid flow and heating effect.

[0061] It should be noted that through the cooperation of the energy-gathering ring 140 and the heater, the heater only heats the liquid entering the first heating part, without heating the liquid in the entire liquid storage cavity 111. Thus, the amount of liquid to be heated is reduced, so as to quickly heat the liquid in the first heating part to generate steam, improve the efficiency of generating steam, thereby improving the heating efficiency and reducing the heating energy consumption.

[0062] It can be understood that a plurality of steam passing holes 121 can be provided on the partition plate 120. The plurality of steam passing holes 121 are evenly spaced and arranged on the partition plate 120 to ensure the uniformity of the steam ejected from the partition plate 120, and ensure that the heating appliance 100 can evenly heat the items on the partition plate 120. Exemplarily, the steam passing holes 121 can be a combination of long strip holes and round holes to increase the flow area of the steam passing holes 121.

[0063] In some examples, as Figures 1 to 3 shown, the above-mentioned energy-gathering ring 140 includes: a first ring body 144; a second ring body 145 sleeved on the first ring body 144, and the liquid inlet 142 is arranged on the second ring body 145; a first connecting plate 146, one end of the first connecting plate 146 is connected to the top end of the first ring body 144, and the other end is connected to the top end of the second ring body 145; a second connecting plate 147, along the extending direction of the first ring body 144, the second connecting plate 147 is connected to the inner side wall of the first ring body 144, and the steam exhaust hole 141 is arranged on the second connecting plate 147; wherein, a first heating part is formed between the inner wall of the second ring body 145 and the outer wall of the heating element 130; a second heating part is formed between the outer wall of the first ring body 144 and the inner wall of the heating element 130.

[0064] It can be understood that the energy-gathering ring 140 may be provided with a first ring body 144, a second ring body 145, a first connecting plate 146 and a second connecting plate 147. Specifically, the first ring body 144 and the second ring body 145 may be arranged along the height direction of the liquid storage cavity 111, and the top ends of the first ring body 144 and the second ring body 145 may be connected by the first connecting plate 146. The first ring body 144, the second ring body 145 and the first connecting plate 146 may enclose to form a heating cavity, and the heating element 130 may be inserted into the heating cavity so that a first heating part is formed between the inner wall of the second ring body 145 and the outer wall of the heating element 130, and a second heating part is formed between the outer wall of the first ring body 144 and the inner wall of the heating element 130. And the liquid inlet 142 may be formed at one end of the second ring body 145 close to the bottom of the liquid storage cavity 111, ensuring that the liquid can still enter the first heating part when the liquid in the liquid storage cavity 111 is less. The heights of the first ring body 144 and the second ring body 145 are both higher than the height of the highest water level line of the liquid storage cavity 111, so as to ensure that the steam formed after the liquid in the first heating part is heated by the heating element 130 can flow into the second heating part, and the steam and the liquid are separated, and the heating element 130 further heats the steam flowing through the second heating part. The second connecting plate 147 may be connected to the inner side wall of the first ring body 144 along the extending direction of the first ring body 144. The inner space of the first ring body 144 may be closed through the second connecting plate 147, and an exhaust hole 141 may be provided in the middle of the second connecting plate 147, and the steam in the second heating part may pass through the exhaust hole 141 and be delivered to the partition plate 120.

[0065] It can be understood that the height of one end of the first ring body 144 away from the partition plate 120 is higher than the height of one end of the second ring body 145 away from the partition plate 120, so as to form a steam passing space at the bottom of the second connecting plate 147. The steam in the second heating part can enter the passing space and be delivered to the partition plate 120 through the exhaust hole 141. With such a setting, a steam passing space can be formed within the height range of the energy-gathering ring 140. There is no need to additionally set a passing space, which may occupy the space of the heating appliance 100, facilitating the spatial layout of the heating appliance 100.

[0066] Exemplarily, the second connecting plate 147 may cover one end of the second connecting plate 147 away from the partition plate 120.

[0067] In some examples, as Figures 1 to 3 shown, the inner side wall of the above-mentioned first ring body 144 and the above-mentioned second connecting plate 147 enclose to form a cavity structure.

[0068] It is understood that the inner sidewall of the first ring body 144 and the side of the second connecting plate 147 facing the partition can be enclosed to form a cavity structure. The cavity structure can serve as a steam passage, allowing the steam in the second heating portion to pass through the steam exhaust hole 141 and be transported to the partition 120 through the steam passage. By providing the cavity structure, a steam passage with a large flow area can be formed, thereby reducing the steam pressure from the steam exhaust hole 141 to the partition 120 and promoting uniform distribution of the steam to the partition 120.

[0069] In some examples, such as Figures 1 to 3 As shown, the exhaust hole 141 is protruded toward the partition plate 120 and is disposed at the middle portion of the second connecting plate 147 .

[0070] It is understood that the steam exhaust hole 141 can be located in the middle of the second connecting plate 147 on the side facing the partition 120, so that the distance between the steam exhaust hole 141 and the second connecting plate 147 is equal at all locations. This ensures that steam in the steam passage space can evenly pass through the steam exhaust hole 141 and enter the steam channel, ensuring uniform steam pressure distribution in the steam passage space and the steam channel. Furthermore, the steam exhaust hole 141 can protrude toward the partition 120, with the protruding portion serving as a guide section to direct steam into the steam channel, thereby improving steam guidance capabilities.

[0071] In some examples, the cross-sectional area of the exhaust hole 141 is greater than or equal to 50 mm along the horizontal direction. 2 .

[0072] It is understandable that, if the cross-sectional area of the exhaust hole 141 is too small in the horizontal direction, the passage of the exhaust hole 141 will be too narrow, and the steam flow rate discharged through the exhaust hole 141 will be too small, resulting in excessive pressure in the steam passage, and the liquid between the energy focusing ring 140 and the heating element 130 will be pushed out by the steam pressure. Therefore, the cross-sectional area of the exhaust hole 141 is set to be greater than or equal to 50mm 2 , to ensure that the steam flow discharged through the exhaust hole 141 is appropriate and to avoid liquid spraying.

[0073] In some examples, such as Figure 4 and Figure 5 As shown, the heating element 130 includes: a panel 131 inserted into the heating chamber, with a mounting groove provided inside the panel 131; and a first heating tube 132 disposed in the mounting groove.

[0074] It can be understood that the heating member 130 can be provided with a shroud 131 and a first heating tube 132. Specifically, the shroud 131 can be inserted into the heating cavity, and the shroud 131 has a certain thickness. An installation groove is formed in the side wall of the shroud 131, and the first heating tube 132 can be installed in the installation groove. With such a setting, a first heating portion is formed between the outer side wall of the shroud 131 and the inner side wall of the second ring body 145; a second heating portion is formed between the inner side wall of the shroud 131 and the outer side wall of the first ring body 144. When the heating appliance 100 performs a heating operation, the liquid in the liquid storage cavity 111 enters the first heating portion from the liquid inlet 142, and the first heating tube 132 is started to heat the outer side wall and the inner side wall of the shroud 131. The liquid in the first heating portion exchanges heat with the outer side wall of the shroud 131 and quickly heats up to generate steam. The steam rises along the outer side wall of the shroud 131 and changes the transmission direction at the first connecting plate 146, enters the second heating portion, and enters the steam passage along the inner side wall of the shroud 131, and then enters the steam passage through the steam discharge hole 141. The steam exchanges heat with the outer side wall and the inner side wall of the shroud 131 that are not in contact with the liquid to increase the steam temperature, thereby increasing the heating temperature of the heating appliance 100.

[0075] It should be noted that the shroud 131 can be made of a heat-resistant material. By arranging the first heating tube 132 inside the shroud 131, it can be avoided that the first heating tube 132 is in direct contact with the liquid, prolonging the service life of the first heating tube 132, and preventing the liquid from causing a short circuit of the first heating tube 132, resulting in a safety accident, and improving safety. Moreover, the position of the placement groove formed in the shroud 131 and the shape of the first heating tube 132 can be determined according to the internal space of the heating appliance 100.

[0076] In some examples, such as Figure 4 and Figure 5 as shown, when the liquid flows into the above-mentioned first heating portion, along the axial direction of the above-mentioned steam discharge hole 141, the projected dimension of the above-mentioned first heating tube 132 is greater than the projected dimension of the highest liquid level in the above-mentioned first heating portion.

[0077] It can be understood that since the first heating part is connected to the liquid storage cavity 111 through the liquid inlet 142. Therefore, the liquid levels of the liquid storage cavity 111 and the first heating part are the same. Along the axial direction of the exhaust hole 141, the highest water level line of the liquid storage cavity 111 is set lower than the height of the first heating tube 132. So that when the liquid level of the first heating part reaches the highest liquid level, there is still a part of the height of the first heating tube 132 exceeding the liquid level of the first heating part. The part of the first heating tube 132 below the liquid level in the first heating part is the first pipe section, and the part of the first heating tube 132 above the liquid level in the first heating part is the second pipe section. With such a setting, the liquid in the first heating part can be heated by the first heat pipe section to generate steam. At the same time, the steam is heated by the second pipe section. Since the first pipe section heats the liquid and the liquid temperature is lower than the steam temperature, the heat exchange amount between the first pipe section and the liquid is large, while the second pipe section does not heat the liquid and is in a dry-burning state, and its temperature is higher than that of the first pipe section, thus ensuring the heating effect on the steam. There is no need to additionally set up a heating device to heat the steam, the structure is simple and reliable, and the heating effect on the steam is good.

[0078] In some examples, along the axial direction of the above exhaust hole 141, the side wall size of the above baffle 131 is greater than or equal to 30 mm; the side wall thickness of the above baffle 131 is greater than or equal to 2 mm and less than or equal to 8 mm.

[0079] It can be understood that along the axial direction of the exhaust hole 141, the side wall height size of the baffle 131 is greater than or equal to 30 mm, so as to ensure that the maximum water storage capacity of the liquid storage cavity 111 meets the heating requirements, avoid replenishing liquid midway, affect the heating efficiency and the user experience, and at the same time ensure that when adding liquid to the liquid storage cavity 111 reaches the highest liquid level of the liquid storage cavity 111, there is still a part of the baffle 131 and the first heating tube 132 exceeding the liquid level height and in a dry-burning state to heat the steam and improve the heating temperature of the heating appliance 100.

[0080] It can be understood that if the side wall thickness size of the baffle 131 is less than 2 mm, the side wall of the baffle 131 is too thin, resulting in weak structural strength of the baffle 131 and unable to protect the first heating tube 132. If the side wall thickness size of the baffle 131 is greater than 8 mm, the side wall of the baffle 131 is too thick, resulting in the baffle 131 occupying too much space and affecting the heating effect of the first heating tube 132. Therefore, the side wall thickness size of the baffle 131 is set to be greater than or equal to 2 mm and less than or equal to 8 mm to ensure that the baffle 131 has sufficient structural strength while ensuring the heating effect of the first heating tube 132 and improving the reliability.

[0081] In some examples, the above first heating tube 132 is arranged in a waveform; or the above first heating tube 132 is arranged in a spiral winding.

[0082] It can be understood that the first heating tube 132 can be arranged in a waveform, and the shape of the placement groove matches the shape of the first heating tube 132. The first heating tube 132 is distributed in wave crests and wave troughs along the height direction of the placement groove. And the wave crest of the first heating tube 132 needs to exceed the maximum liquid level height of the liquid storage cavity 111. The placement groove can also be set as an annular groove body, and the first heating tube 132 can be spirally arranged in the annular groove body. And there is a spiral section height of the first heating tube 132 exceeding the maximum liquid level height of the liquid storage cavity 111. With such a setting, the heating area of the first heating tube 132 can be increased, and the liquid and steam can be heated quickly.

[0083] In some examples, such as Figure 1 As shown, the above-mentioned heating appliance 100 further includes: a plate body 150, which seals one end of the above-mentioned surrounding plate 131 away from the above-mentioned partition plate 120. An over-steam channel is formed between the plate body 150 and the second connecting plate 147, and the over-steam channel is respectively communicated with the second heating part and the exhaust hole 141.

[0084] It can be understood that the heating appliance 100 is also provided with a plate body 150. Specifically, the plate body 150 can seal one end of the surrounding plate 131 away from the partition plate 120 to close the bottom of the surrounding plate 131. And the plate body 150 can be located at the bottom of the second connecting plate 147, and an over-steam channel can be formed between the plate body 150 and the second connecting plate 147. With such a setting, the steam in the second heating part can be transported along the over-steam channel to the exhaust hole 141, flow into the steam channel through the exhaust hole 141, and be discharged from the steam passing hole 121 of the partition plate 120. The over-steam channel can better guide the flow direction of the steam and avoid the escape of steam.

[0085] It can be understood that the plate body 150 can bulge towards the direction of the exhaust hole 141, so that the steam in the over-steam channel can quickly converge at the exhaust hole 141, improve the flow speed of the steam, and avoid excessive pressure in the over-steam channel. Similarly, the middle part of the second connecting plate 147 can protrude towards the partition plate 120, and the exhaust hole 141 can be located at the highest point of the protrusion of the second connecting plate 147. Ensure the flow area of the over-steam channel, avoid too narrow positions, and ensure the smooth flow of steam. The bulging angle of the plate body 150 can be the same as the protruding angle of the second connecting plate 147, so that the cross-sectional area of the over-steam channel along the vertical direction is equal.

[0086] In some examples, the above-mentioned heating element 130 further includes: a second heating tube, which is arranged at one end of the plate body 150 away from the partition plate 120.

[0087] It can be understood that the heating member 130 may also be provided with a second heating tube. Specifically, the second heating tube may be disposed at the bottom of the plate body 150, and the side of the plate body 150 facing the steam passage can be heated through the second heating tube. Thus, when steam is delivered to the steam passage, the second heating tube continuously heats the steam in the steam passage, further increasing the steam temperature and the heating temperature of the heating appliance 100.

[0088] Exemplarily, the second heating tube may be arranged in a serpentine shape at the bottom of the plate body 150 to increase the heating area of the second heating tube and ensure uniform heating of the second heating tube.

[0089] In some examples, as Figure 1 shown, the above-mentioned heating appliance 100 further includes: a deflector 160, disposed in the above-mentioned housing 110, between the above-mentioned first connecting plate 146 and the above-mentioned partition plate 120, for uniformly guiding the steam ejected through the above-mentioned steam discharge hole 141 to the above-mentioned partition plate 120.

[0090] It can be understood that the heating appliance 100 may also be provided with a deflector 160. Specifically, the deflector 160 may be disposed in the housing 110 and between the partition plate 120 and the first connecting plate 146. And the projected area of the deflector 160 on the partition plate 120 is greater than or equal to the projected area of the steam passage on the partition plate 120. With such a setting, the steam in the steam passage can be sprayed onto the deflector 160. After being blocked by the deflector 160, the steam flows to the side of the deflector 160 and then is delivered above the partition plate 120 through the steam hole 121 to heat the item to be heated placed on the partition plate 120.

[0091] In some examples, as Figure 1 shown, the above-mentioned heating appliance 100 further includes: a tray 170, disposed on the side of the above-mentioned partition plate 120 facing the above-mentioned heating member 130 and communicating with the above-mentioned steam hole 121.

[0092] It can be understood that the heating appliance 100 is also provided with a tray 170. The tray 170 can be sleeved on the baffle, and the tray 170 is connected to the side of the partition plate 120 facing the heating member 130 and communicates with the steam hole 121. With such a setting, considering that when steam passes through the steam hole 121 of the partition plate 120 to heat the item to be heated, heat exchange occurs between the steam, the partition plate 120, and the item to be heated, causing the temperature of the steam to decrease and condensing into liquid. The liquid drips through the steam hole 121 into the tray 170 to centrally collect the dripping liquid, which is convenient for subsequent treatment and avoids the dripping liquid from affecting the liquid in the liquid storage cavity 111.

A cooking space is formed in the pot body 210, ingredients can be placed in the cooking space, and the cooking space can communicate with the steam channel through the steam holes 121. The pot lid 220 can cover the open mouth of the pot body 210 to reduce the loss of steam in the cooking space and improve the heating efficiency. After injecting liquid into the liquid storage cavity 111, the liquid is heated by the heating element 130, and the steam generated by heating is transported into the cooking space through the steam holes 121 of the partition 120. Due to the combined action of the energy gathering ring 140 and the heating element 130, the steam generated by the heating appliance 100 has a relatively high temperature to quickly heat the ingredients in the cooking space. Thus, it is possible to quickly cook ingredients such as meat and grains that require a relatively long cooking time, reduce the loss of nutritional components of the ingredients, and improve the user experience.

[0095] In some examples, as Figure 6 shown, a plurality of the pot bodies 210 are provided, and the partition 120 is disposed between adjacent pot bodies 210.

[0096] It can be understood that a plurality of pot bodies 210 can be provided, and the plurality of pot bodies 210 are stacked and arranged, and the plurality of pot bodies 210 communicate with each other. And the partition 120 is disposed between adjacent pot bodies 210. The ingredients in the cooking space of the pot body 210 can be placed on the partition 120, and the heating appliance 100 can heat a plurality of pot bodies 210 simultaneously to heat a large amount of ingredients at one time and improve the cooking efficiency. And the user can plan by himself / herself the ingredients placed in each layer of the pot body 210 to improve the user experience.
