Description

[Technical field]

[0001] The invention relates to the technical field of electric hot pots, in particular to a low steam emission, water-saving and non-stick electric hot pot. [Background technology]

[0002] The electric hot pot in the prior art generally uses a bottom heating plate or an IH coil to directly heat the inner pot. When the bottom plate is heated or the IH is used to cook rice, due to the thermal inertia of the heated inner pot, the rice will become very sticky due to the gelatinization of the rice during the cooking process. In order to prevent the rice from sticking to the inner pot, a non-stick coating is generally required on the inner wall of the inner pot, which will cause an increase in manufacturing costs. For this reason, a water bath heated electric hot pot has been developed in the prior art, including an outer pot filled with water and an inner pot placed in the outer pot. A heating device is provided at the bottom of the outer pot. The heating device heats water to achieve water bath heating of the inner pot. Water bath heating can make the rice in the inner pot be heated more evenly, and the temperature is about 110°C, so the food in the inner pot is not easy to stick to the pot, which can solve the non-stick problem. However, since the interior of the electric hot pot is a non-enclosed space, the steam generated by the water bath heating will be continuously discharged, resulting in a low steam utilization rate and excessive water consumption, thereby increasing energy consumption. [Summary of the invention]

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an electric hot pot with good cooking effect, which can not only collect steam through the steam insulation cavity to improve the insulation effect of the cooking cavity, but also drain the condensed water in the steam insulation cavity into the outer pot through the reflux hole to reduce the total water consumption, thereby reducing energy consumption.

[0008] Furthermore, the upper cover includes a flat top, the lower cover includes an upwardly arched dome, the dome includes a top and a side, the contraction portion is formed between the top and the flat top, and the expansion portion is formed between the side and the flat top.

[0009] Furthermore, the upper cover also includes an outer wall extending downward from the edge of the flat top, and the lower cover also includes an inner wall extending downward from the edge of the dome, the outer wall and the inner wall surround the outside of the inner pot and are sealed, and the reflux hole is arranged on the inner wall.

[0010] Furthermore, a sealing ring is detachably installed between the outer wall and the inner wall.

[0011] Furthermore, the pot cover also includes a decorative cover, the upper cover is fixed inside the decorative cover, and the decorative cover is provided with an air outlet corresponding to the air outlet.

[0012] Furthermore, the top wall of the decorative cover is provided with a fixing column extending downward, the upper cover is provided with a fixing hole, and the fixing column is interference fit with the fixing hole.

[0013] Furthermore, the height of the reflux hole is lower than the mouth of the inner pot to prevent the steam condensate from flowing back into the inner pot through the reflux hole.

[0014] Furthermore, a flow gap is provided between the pot cover and the pot edge of the inner pot, and the steam channel is connected with the cooking cavity through the flow gap.

[0015] Beneficial effects of the present invention:

[0016] When the non-stick electric hot pot of the present invention is used, a certain amount of water is first injected into the outer pot, the inner pot is placed in the outer pot, and then the heating device is turned on to heat the water in the outer pot to achieve water bath heating of the inner pot. Steam is generated after the water in the outer pot boils, and the steam enters the steam insulation cavity through the steam channel for reuse. Since the steam insulation cavity extends from the central part of the pot cover to the peripheral side of the pot cover and covers the cooking cavity, the steam diffuses and fills the entire steam insulation cavity after entering the steam insulation cavity and forms a steam insulation layer. The steam insulation layer achieves insulation of the entire top of the cooking cavity, thereby improving the cooking effect; in addition, the steam insulation cavity can also guide the collected condensed water into the outer pot through the reflux hole, thereby achieving water recycling, thereby reducing the total water consumption of the outer pot; finally, since the temperature of the condensed water is generally high, after being reused, the energy consumption required for heating the water can be reduced, thereby reducing the energy consumption of the product.

[0017] The pot cover comprises an upper cover and a lower cover which are connected by sealing edges, a steam insulation cavity is formed between the upper cover and the lower cover, an air inlet hole which connects the cooking cavity and the steam insulation cavity is provided on the lower cover, and an exhaust hole is provided on the upper cover and deviates from the air inlet hole. With such a design, the steam insulation cavity can be defined after the upper cover and the lower cover are assembled, and there is no need to process the steam insulation cavity separately, so the structure is relatively simple; in addition, the exhaust hole is provided on the upper cover and deviates from the air inlet hole, so that the steam can be prevented from entering the steam insulation cavity through the air inlet hole and then being directly discharged from the exhaust hole, so that the steam can diffuse and fill the entire steam insulation cavity.

[0018] The steam insulation chamber includes a contraction portion and an expansion portion surrounding the outside of the contraction portion, the height of the expansion portion is greater than the height of the contraction portion, and the air inlet is arranged corresponding to the contraction portion. With such a design, the pressure of steam can be released when it flows from the contraction portion to the expansion portion, so as to reduce the condensation temperature, thereby making it easier for steam to condense in the steam insulation chamber, so as to effectively reduce the amount of steam discharged and improve the utilization rate of condensed water.

[0019] The upper cover includes a flat top, the lower cover includes an upwardly arched dome, the dome includes a top and a side, a contraction portion is formed between the top and the flat top, and an expansion portion is formed between the side and the flat top. With such a design, condensed water condensed on the bottom surface of the lower cover can flow along the dome to the outer peripheral side of the lower cover, so as to prevent the condensed water from dripping on the rice in the cooking cavity, thereby ensuring the taste of the rice.

[0020] The upper cover also includes an outer wall extending downward from the edge of the flat top, and the lower cover also includes an inner wall extending downward from the edge of the dome. The outer wall and the inner wall surround the outer side of the inner pot and are sealed and connected, and the reflux hole is provided on the inner wall. With such a design, the steam in the steam channel can enter the steam insulation cavity through the reflux hole for insulation in the early stage of cooking, and as condensed water is formed, the condensed water in the steam insulation cavity can be collected between the inner wall and the outer wall, and dripped into the outer pot through the reflux hole for recycling.

[0021] A sealing ring is removably installed between the outer wall and the inner wall. Such a design makes assembly simple and convenient for later disassembly of the upper cover and the lower cover to clean the steam insulation chamber.

[0022] The pot cover also includes a decorative cover, the upper cover is fixed inside the decorative cover, and the decorative cover is provided with an air outlet corresponding to the air outlet. Such a design can improve the appearance of the non-stick electric hot pot and increase the market competitiveness of the product.

[0023] The top wall of the decorative cover is provided with a fixing column extending downward, the upper cover is provided with a fixing hole, and the fixing column and the fixing hole are interference fit. Such a design has a simple structure and is easy to assemble.

[0024] The height of the reflux hole is lower than the mouth of the inner pot to prevent the steam condensed water from flowing back into the inner pot through the reflux hole. By designing the height of the reflux hole, it is ensured that the condensed water flowing back from the reflux hole flows into the outer pot to replenish the water in the outer pot, and does not flow back into the inner pot, causing the rice in the inner pot to be wet.

[0025] The upper and lower covers are both made of stainless steel, and the decorative cover is a resin part. The upper and lower covers are made of stainless steel to prevent them from being deformed due to high temperature, thereby ensuring the shape of the steam insulation chamber; while the decorative cover is a resin part, and the decorative cover can be designed in different colors as needed to enhance the aesthetics of the product.

[0026] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[Specific implementation method]

[0034] The present invention provides a low steam emission and water-saving non-stick electric hot pot, comprising a pot cover, an outer pot filled with water and an inner pot accommodated in the outer pot, the pot cover is covered on the outer pot and cooperates with the inner pot to form a cooking cavity, the outer pot is provided with a heating device, a steam channel connected to the cooking cavity is provided between the outer pot and the inner pot, the pot cover is also provided with a steam insulation cavity connected to the cooking cavity, the steam insulation cavity extends from the central part of the pot cover toward the peripheral side of the pot cover to cover the cooking cavity, the top of the steam insulation cavity is provided with an exhaust hole connected to the outside, and the bottom of the steam insulation cavity is provided with a reflux hole connected to the steam channel.

[0035] When the non-stick electric hot pot of the present invention is used, a certain amount of water is first injected into the outer pot, the inner pot is placed in the outer pot, and then the heating device is turned on to heat the water in the outer pot to achieve water bath heating of the inner pot. Steam is generated after the water in the outer pot boils, and the steam enters the steam insulation cavity through the steam channel for reuse. Since the steam insulation cavity extends from the central part of the pot cover to the peripheral side of the pot cover and covers the cooking cavity, the steam diffuses and fills the entire steam insulation cavity after entering the steam insulation cavity and forms a steam insulation layer. The steam insulation layer achieves insulation of the entire top of the cooking cavity, thereby improving the cooking effect; in addition, the steam insulation cavity can also guide the collected condensed water into the outer pot through the reflux hole, thereby achieving water recycling, thereby reducing the total water consumption of the outer pot; finally, since the temperature of the condensed water is generally high, after being reused, the energy consumption required for heating the water can be reduced, thereby reducing the energy consumption of the product.

[0036] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0037] Reference Figures 1 to 4As shown, the non-stick electric hot pot in this preferred embodiment includes a pot cover 100, an outer pot 200 filled with water, and an inner pot 300 accommodated in the outer pot 200. The pot cover 100 covers the outer pot 200 and cooperates with the inner pot 300 to form a cooking cavity 01. The bottom of the outer pot 200 is provided with a heating device 400. The heating device 400 The inner pot 300 includes an inner heating tube 410 and / or an outer heating tube 420. The inner heating tube 410 directly heats the bottom wall of the inner pot 300. The outer heating tube 420 surrounds the outer side of the inner heating tube 410 and forms a gap 02 with the bottom wall of the inner pot 300. There is water in the gap 02. The inner pot 300 can be heated in a water bath by heating with the inner heating tube 410 and / or the outer heating tube 420. In order to improve the heating efficiency, the heating device 400 in this embodiment preferably includes an inner heating tube 410 and an outer heating tube 420. In addition, in this embodiment, a steam channel connected to the cooking cavity 01 is provided between the side wall of the outer pot 200 and the side wall of the inner pot 300. , steam can enter the cooking cavity 01 to heat the top of the rice, and combined with the bottom water bath heating, the heating uniformity of the rice can be further improved to avoid the rice being undercooked, thereby improving the cooking taste of the rice; finally, the pot cover 100 in this embodiment is also provided with a steam insulation cavity 03 connected to the cooking cavity 01, and the steam insulation cavity 03 extends from the central part of the pot cover 100 toward the surrounding side of the pot cover 100 to cover the cooking cavity 01, that is, the entire top of the cooking cavity 01 is insulated, and the top of the steam insulation cavity 03 is provided with an exhaust hole 031 connected to the outside, and the bottom of the steam insulation cavity 03 is provided with a reflux hole 032 connected to the steam channel.

[0038] When the non-stick electric hot pot of the present embodiment is used, a certain amount of water is firstly poured into the outer pot 200, the inner pot 300 is placed in the outer pot 200, and then the heating device 400 is turned on to heat the water in the outer pot 200 to achieve water bath heating of the inner pot 300. Steam is generated after the water in the outer pot 200 boils, and the steam enters the steam insulation cavity 03 through the steam channel for reuse. Since the steam insulation cavity 03 extends from the center of the pot cover 100 to the peripheral side of the pot cover 100 and covers the cooking cavity 01, the steam enters the steam insulation cavity 03. After entering the steam insulation cavity 03, the steam will diffuse and fill the entire steam insulation cavity 03 and form a steam insulation layer. The steam insulation layer can insulate the entire top of the cooking cavity 01, thereby improving the cooking effect. In addition, the collected condensed water in the steam insulation cavity 03 can also be guided to the outer pot 200 through the reflux hole 032 to achieve water recycling, thereby reducing the total water consumption of the outer pot 200. Finally, since the temperature of the condensed water is generally high, after it is reused, the energy consumption required for heating the water can be reduced, thereby reducing the energy consumption of the product.

[0039] Specifically, the pot cover 100 in this embodiment includes an upper cover 110 and a lower cover 120 which are sealed and connected at the edges. After the upper cover 110 and the lower cover 120 are assembled, the above-mentioned steam insulation cavity 03 can be formed between the two, and there is no need to process the steam insulation cavity 03 separately. Therefore, the structure is relatively simple and the processing difficulty is relatively low. After the pot cover 100 is covered on the outer pot 200, the lower cover 120 cooperates with the inner pot 300 to form the above-mentioned cooking cavity 01, and a flow gap is provided between the lower cover 120 and the pot edge of the inner pot 300, and the steam channel is connected with the cooking cavity 01 through the flow gap. In addition, the lower cover 120 is also provided with an air inlet hole 121 connecting the cooking cavity 01 and the steam insulation cavity 03. The air inlet hole 121 is a small hole. Since the exhaust resistance of the small hole is relatively large, a smaller positive pressure can be formed for the cooking cavity 01, so that the steam can diffuse and fill the steam insulation cavity 03 more easily; and the exhaust hole 031 is provided on the upper cover 110 and deviates from the air inlet hole 121. Such a design can prevent the steam from entering the steam insulation cavity 03 through the air inlet hole 121 and then being directly discharged from the exhaust hole 031, thereby allowing the steam to diffuse and fill the entire steam insulation cavity 03, thereby ensuring the insulation effect of the cooking cavity 01.

[0040] In order to reduce the discharge of steam, the steam insulation chamber 03 in this embodiment includes a contraction portion 033 and an expansion portion 034 surrounding the outside of the contraction portion 033. The height of the expansion portion 034 is greater than the height of the contraction portion 033, and the air inlet 121 is arranged corresponding to the contraction portion 033. Such a design can release the pressure of steam when it flows from the contraction portion 033 to the expansion portion 034, so as to reduce the condensation temperature, thereby making it easier for the steam to condense in the steam insulation chamber 03, so as to effectively reduce the discharge amount of steam and improve the utilization rate of condensed water.

[0041] In order to form the steam insulation cavity 03 of the above-mentioned shape, the upper cover 110 in this embodiment includes a flat top 111, and the lower cover 120 includes an upwardly arched dome 122, the dome 122 includes a top and a side extending downward from the top, the above-mentioned contraction portion 033 is formed between the top and the flat top 111, and an extension portion 034 is formed between the side and the flat top 111, and the outer side of the extension portion 034 extends to the outside of the cooking cavity 01, thereby enabling the condensed water condensed on the bottom surface of the lower cover 120 to flow along the dome 122 to the outer peripheral side of the lower cover 120, thereby avoiding residual accumulation of condensed water and avoiding condensed water dripping on the rice in the cooking cavity 01, thereby ensuring the taste of the rice.

[0042] It can be understood that in other embodiments of the present invention, the longitudinal section of the top wall of the lower cover is arched, that is, the bottom surface of the top wall is a plane, the top surface of the top wall is an upwardly arched arc surface, a contraction portion is formed between the central portion of the arc surface and the flat top, and an expansion portion is formed between other portions of the arc surface and the flat top.

[0043] It is understandable that in other embodiments of the present invention, the lower cover includes a flat top, and the upper cover includes a downwardly concave arc plate, a contraction portion is formed between the bottom of the arc plate and the flat top, and an expansion portion is formed between the side of the arc plate and the flat top.

[0044] In addition, the upper cover 110 in this embodiment further includes an outer side wall 112 extending downward from the edge of the flat top 111, and the lower cover 120 further includes an inner side wall 123 extending downward from the edge of the dome 122. The outer side wall 112 and the inner side wall 123 surround the outer side of the inner pot 300, and a sealing ring 130 is sandwiched between the outer side wall 112 and the inner side wall 123. The sealing ring 130 includes a body, a connecting ring and a sealing protrusion. The connecting ring is formed by extending upward from the outer peripheral side of the body, and the sealing protrusion is formed by extending upward from the top surface of the body. The connecting ring is sleeved on the outside of the outer wall 112 and fixed with the outer wall 112, the sealing protrusion is inserted between the outer wall 112 and the inner wall 123 to seal the gap therebetween, and the bottom surface of the inner wall 123 is against the body, thereby realizing the sealed connection between the outer wall 112 and the inner wall 123, and when the pot cover 100 is closed on the outer pot 200, the sealing ring 130 is pressed on the top of the outer pot 200, and the reflux hole 032 is a notch provided on the inner wall 123, so that the reflux hole 032 is connected with the steam channel. Such a design is simple to assemble and convenient to disassemble the upper cover 110 and the lower cover 120 for cleaning the steam insulation chamber 03 at a later time. In addition, in the early stage of cooking, the steam in the steam channel can enter the steam insulation chamber 03 through the reflux hole 032 for insulation. As condensed water is formed, the condensed water in the steam insulation chamber 03 can be collected between the inner wall 123 and the outer wall 112, and drip into the outer pot 200 through the reflux hole 032 for recycling.

[0045] It can be understood that in other embodiments of the present invention, the outer side wall and the inner side wall can also be welded and sealed.

[0046] It can be understood that in other embodiments of the present invention, the upper cover only includes a flat top, and the lower cover only includes a dome, both the flat top and the dome cover the cooking cavity, and a sealing ring is provided on the edge of the flat top and the edge of the dome. At this time, the drain outlet is arranged near the edge of the dome and is located above the steam channel.

[0047] In order to prevent the upper cover 110 and the lower cover 120 from deforming due to high temperature and causing the shape of the steam insulation chamber 03 to change, the upper cover 110 and the lower cover 120 in this embodiment are both stainless steel parts. Since the stainless steel parts have a single color and cannot be well matched with the appearance of the outer pot 200, the pot cover 100 in this embodiment also includes a decorative cover 140. The upper cover 110 is fixed in the decorative cover 140. The decorative cover 140 is a resin part. In this way, the decorative cover 140 can be designed into different colors as needed to match the outer pot 200, thereby improving the aesthetics of the product and increasing the market competitiveness of the product.

[0048] In order to simplify the structure and make the assembly of the upper cover 110 and the decorative cover 140 easier and more convenient, in this embodiment, the top wall of the decorative cover 140 is provided with a downwardly extending fixing column 141, and the flat top 111 is provided with a fixing hole 113. The fixing column 141 and the fixing hole 113 are interference fit, so that the upper cover 110 is fixed in the decorative cover 140. The decorative cover 140 is provided with an exhaust hole 142 corresponding to the exhaust hole 031 to ensure the discharge of part of the steam.

[0049] In this embodiment, reference can be made to Figure 2 and Figure 4 The height of the reflux hole 032 is lower than the mouth of the inner pot 300 to prevent the steam condensed water from flowing back into the inner pot 300 through the reflux hole 032. By designing the height of the reflux hole, it is ensured that the condensed water flowing back from the reflux hole flows into the outer pot 200 to replenish the moisture in the outer pot, and does not flow back into the inner pot, causing the rice in the inner pot to be wet. In order to ensure a good reflux effect and avoid the residue of condensed water in the steam insulation chamber 03, the reflux hole 032 is set at the lowest point of the steam insulation chamber 03.

[0050] In this embodiment, reference can be made to Figure 2 There is a first gap between the outer pot 200 and the inner pot 300, and a second gap between the lower cover 120 and the edge of the inner pot 300. The first gap and the second gap constitute a steam channel. The steam generated in the outer pot 200 rises through the first gap between the inner pot 300 and the outer pot 200, and enters the cooking cavity through the second gap to steam-heat the food in the cooking cavity. On the other hand, the water in the outer pot 200 can heat the inner pot in a water bath. During the rising process, the steam enters the steam insulation cavity 03 through the air inlet 121. Part of the steam in the steam insulation cavity 03 will be discharged to the outside through the exhaust hole, and part of it will condense to form condensed water and flow back to the outer pot 200 through the reflux hole 032. Different from ordinary bottom-heated rice cookers, the present application is to set water in the outer pot, heat the water to generate steam and heat the rice in the inner pot 300, so the temperature of the inner pot 300 will not be too high, which can prevent the rice from gelatinizing and sticking to the pot. The present application utilizes water in the outer pot for heating, and a large amount of steam is generated during the heating process. The design of the steam channel and the reflux hole 032 ensures that the steam passes through the steam channel to cook the inner pot. The double-layer design of the pot cover 100 achieves the heat preservation effect while reducing the generation of condensed water. The shape of the pot cover is designed so that the condensed water can flow back into the outer pot 200, which can be reused and save resources.

[0051] It is understandable that in other embodiments of the present invention, the upper cover may also be fixed in the decorative cover by means of snap connection or screw connection.

[0052] It is understandable that in other embodiments of the present invention, the upper cover and the lower cover may also be integrally formed of high temperature resistant resin parts, and the steam insulation cavity may be formed by a blow molding process. With this design, the decorative cover may be omitted.

[0053] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
