Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electric hot pot technology, specifically relating to a heat circulation electric hot pot. Background Technology
[0002] An electric hot pot is a type of hot pot appliance that uses electricity for heating. It's simple to operate, safe, and convenient, making it suitable for families and small gatherings. It requires no open flame, offers precise temperature control, and is easy to clean. Besides hot pot, electric hot pots can also be used to cook soups, stews, and more, offering versatility. When choosing an electric hot pot, factors such as power, capacity, heating evenness, and ease of cleaning should be considered. It makes hot pot a more convenient dining experience, especially suitable for modern families or busy individuals.
[0003] Problems with existing technology: Most existing hot pots use resistance heating, which involves a large amount of current passing through the resistance wire during heating. The resistance wire in a household electric hot pot can reach a temperature of up to 350°C. This heat is transferred to cook the soup and ingredients in the hot pot. However, a large amount of heat is lost through thermal radiation during this process, which is wasteful as it cannot be reused. Utility Model Content
[0004] The purpose of this invention is to provide a heat-circulating electric hot pot that, when heating the pot, absorbs heat from the heating wire through a heat-absorbing ring. After heating, the heat-absorbing ring enters the heat-insulating cavity and transfers heat to the heating ring. When the pot needs to be kept warm or reheated, the heating ring is pushed against the pot to achieve heat transfer and reuse the heat that was originally lost.
[0005] The specific technical solution adopted by this utility model is as follows: A heat circulation electric hot pot includes: a table, a heating pot is provided at the top of the table, and an electric heating wire is fixedly installed on the table near the bottom of the heating pot; The table is provided with heat preservation chambers on both sides near the heating pot, and the heat preservation chambers extend to both sides of the heating wire; Heating rings are provided on both sides of the heat preservation cavity near the heating pot, and heat absorption rings are provided on both sides of the heat preservation cavity near the heating wire. An isolation cover is provided between the heat preservation cavity and the heating pot and the heating wire, and the isolation cover is used to isolate the heat preservation cavity from the heating pot and the heating wire.
[0006] A heat insulation groove is provided on one side of the two heating rings that are far apart from each other, and an electronic push rod is provided inside the heat insulation groove.
[0007] A heat insulation groove is provided on one side of the two heat-absorbing rings that are far apart from each other, and an electronic push rod is provided inside the heat insulation groove.
[0008] A heat insulation ring is provided near the end of the output end of both electronic actuator one and electronic actuator two.
[0009] Heat-conducting blocks are fixedly connected to the positions between the heating rings and heat-absorbing rings on both sides of the table.
[0010] The table is made entirely of heat-insulating materials.
[0011] A lifting hydraulic rod is installed at the lower part of the isolation cover, and the end of the lifting hydraulic rod is fixedly connected to the isolation cover.
[0012] A protective cover is fixedly installed on the top of the lifting hydraulic rod near the periphery of the isolation cover.
[0013] The heat-absorbing ring is made of a material with low specific heat capacity, high temperature resistance, and high thermal conductivity.
[0014] The heating ring is made of a material with high specific heat capacity, high temperature resistance, and strong thermal conductivity.
[0015] The technical effects achieved by this utility model are as follows: In this invention, the heat-absorbing ring approaches the heating wire under the push of the second electronic pusher when the heating pot is heated, thereby absorbing the heat generated by the thermal radiation of the heating wire. When the heating pot is finished heating, the heat-absorbing ring enters the interior of the heat preservation cavity and transfers the heat to the heating ring through the heat-conducting block. When the heating pot needs to be kept warm or reheated, the first electronic pusher pushes the heating ring to fit against the heating pot, realizing the transfer of heat and making use of the originally lost heat.
[0016] This invention utilizes the low specific heat capacity of the heat-absorbing ring to rapidly increase its temperature during the heating process of the heating wire. The heat-absorbing ring transfers heat to the heating ring through the heat-conducting block and thermal radiation. Due to the larger volume and higher specific heat capacity of the heating ring, when the heat of the heat-absorbing ring decreases to the same temperature as the heating ring, more heat will be transferred to the heating ring, thus increasing the recycling rate.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0020] like Figures 1-2 As shown, a heat circulation electric hot pot includes: a table 1, a heating pot 2 is provided at the top of the table 1, and an electric heating wire 3 is fixedly installed on the table 1 near the bottom of the heating pot 2.
[0021] In a traditional electric hot pot, electricity is applied to the heating wire 3, which generates high temperatures to heat the broth in the pot 2. Most of the heat from the heating wire 3 is transferred to the table 1 via thermal radiation and then dissipated through the outside environment.
[0022] See attached document Figures 3-4 The table 1 has heat-insulating chambers 106 on both sides near the heating pot 2, and the heat-insulating chambers 106 extend to both sides of the heating wire 3. Heating rings 101 are arranged on both sides of the heat-insulating chambers 106 near the heating pot 2, and heat-absorbing rings 102 are arranged on both sides of the heat-insulating chambers 106 near the heating wire 3. A heat-insulating groove 1 is arranged on the side of the two heating rings 101 that is far apart from each other, and an electronic push rod 1 is arranged inside the heat-insulating groove 1. A heat-insulating groove 2 is arranged on the side of the two heat-absorbing rings 102 that is far apart from each other, and an electronic push rod 2 is arranged inside the heat-insulating groove 2. A heat-insulating ring 104 is arranged near the output end of the electronic push rod 1 and the electronic push rod 2. Heat-conducting blocks 105 are fixedly connected to the positions between the heating rings 101 and the heat-absorbing rings 102 on both sides of the table 1. The table 1 is made of heat-insulating material.
[0023] According to the above structure, when heating the pot 2, the heating ring 101 stays inside the heat preservation cavity 106, while the heat-absorbing ring 102 approaches the heating wire 3 under the push of the electronic push rod 2, thereby absorbing the heat generated by the heat radiation of the heating wire 3. The two heat-conducting blocks 105 can surround the heating wire 3. When the soup in the pot 2 boils, the heating of the heating wire 3 is stopped. At this time, the heat-absorbing ring 102 enters the heat preservation cavity 106. The heat-absorbing ring 102 transfers heat to the heating ring 101 through the heat-conducting blocks 105, so that the temperature of the heating ring 101 rises rapidly and is kept warm. When the pot 2 needs to be kept warm or reheated, the heating ring 101 is pushed to fit against the pot 2 by the electronic push rod 1 to realize the transfer of heat. The function of the heat insulation ring 104 is to isolate the heat transfer between the electronic push rod 1 and the electronic push rod 2 and the heating ring 101 and the heat absorption ring 102. The heat insulation design of the table 1 is also to protect the electronic components inside the electronic push rod.
[0024] See attached document Figures 3-5 An isolation cover 4 is provided between the heat preservation cavity 106 and the heating pot 2 and the heating wire 3. The isolation cover 4 is used to isolate the heat preservation cavity 106 from the heating pot 2 and the heating wire 3. A lifting hydraulic rod 401 is provided below the isolation cover 4, and the end of the lifting hydraulic rod 401 is fixedly connected to the isolation cover 4. A protective cover 103 is fixedly installed on the top of the lifting hydraulic rod 401 near the outer periphery of the isolation cover 4. The heat absorption ring 102 is made of a material with low specific heat capacity, high temperature resistance and high thermal conductivity. The heating ring 101 is made of a material with high specific heat capacity, high temperature resistance and high thermal conductivity.
[0025] According to the above structure, the isolation cover 4 is used to isolate the heat insulation cavity 106 when the heat absorption ring 102 returns to the heat insulation cavity 106 after heating, thereby reducing heat loss inside and providing a sealed environment for the heat absorption ring 102 to transfer heat to the heating ring 101. The low specific heat capacity of the heat-absorbing ring 102 allows it to rapidly increase its temperature during the heating process of the heating wire 3, reaching a maximum temperature of 350°C. When the heat-absorbing ring 102 returns to the heat-insulating cavity 106, the isolation cover 4 seals the heat-insulating cavity 106. The heat-absorbing ring 102 transfers heat to the heating ring 101 through the heat-conducting block 105 and thermal radiation. Since the heating ring 101 has a larger volume and higher specific heat capacity, when the heat of the heat-absorbing ring 102 decreases to the same temperature as the heating ring 101, the heat of the heat-absorbing ring 102 is much less than that of the heating ring 101. The heating ring 101 has a large amount of heat. When it is necessary to heat the heating pot 2, since the highest temperature inside the heating pot 2 is 1°C, the heating ring 101 can be close to the heating pot 2 to transfer heat to the inside of the heating pot 2. To illustrate, consider this example: When the heat-absorbing ring 102 is heated to 350°C, it enters the insulation cavity 106. Since the heating ring 101 has a relatively large specific heat capacity and volume and a lower temperature, the heat-absorbing ring 102 will transfer heat to the heating ring 101. When the two temperatures reach equilibrium, the temperature is approximately 110°C. At this point, the heat-absorbing ring 102 retains about 30% of its original heat, while the heating ring 101 receives about 70% of the original heat from the heat-absorbing ring 102. Since the temperature of the heating ring 101 is higher than the temperature inside the heating pot 2, it can transfer its own temperature to the heating pot 2 to heat the heating pot 2. This process can be implemented by setting up a thermometer for precise measurement and calculation, and then controlling it via a PLC. Alternatively, it can be based on repeated testing and automatically adjust the heat flow direction using a big data model.
[0026] The working principle of this utility model is as follows: When heating the heating pot 2, the heat-absorbing ring 102 approaches the heating wire 3 under the push of the electronic push rod 2, thereby absorbing the heat generated by the heat radiation of the heating wire 3. When the soup in the heating pot 2 boils, the heating of the heating wire 3 is stopped. At this time, the heat-absorbing ring 102 enters the interior of the heat preservation cavity 106, and the heat-absorbing ring 102 transfers the heat to the heating ring 101 through the heat-conducting block 105. Because the low specific heat capacity of the heat-absorbing ring 102 allows it to quickly increase its temperature during the heating process of the heating wire 3, the heat-absorbing ring 102 transfers heat to the heating ring 101 through the heat-conducting block 105 and thermal radiation. Since the heating ring 101 has a large volume and a high specific heat capacity, when the heat of the heat-absorbing ring 102 drops to the same temperature as the heating ring 101, more heat will be transferred to the heating ring 101, thus increasing the recycling rate. When the heating pot 2 needs to be kept warm or reheated, the heating ring 101 is pushed to fit against the heating pot 2 by the electronic push rod, so as to realize the heat transfer and reuse the originally lost heat.
[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
