Abstract
Description
Technical Field
[0001] This utility model relates to electric slow cookers, and more particularly to an air-cooled electric slow cooker. Background Technology
[0002] Electric slow cookers are a common cooking appliance. They typically have an inner pot placed inside the main pot, and a heating element located inside the main pot heats the food in the inner pot.
[0003] To meet users' needs for enjoying warm food anytime, most electric slow cookers on the market are equipped with a keep-warm function. After completing the cooking program, the slow cooker automatically switches to keep-warm mode, continuously providing lower power to keep the food at a higher temperature. This keep-warm design, to some extent, prevents food from losing its taste and nutrition due to cooling, but it also brings new problems. The inner pot of electric slow cookers is mostly made of ceramic, which has poor thermal conductivity and slow heat dissipation. Even after the inner pot is removed from the slow cooker, the food is difficult to cool to a suitable eating temperature in a short time, sometimes leading to overcooking and mushy food. In addition, when users are ready to eat, the food that has been kept warm for a long time is often too hot to eat immediately. This is especially true for office workers who pre-set porridge in the evening and hope to quickly enjoy a bowl of nutritious porridge at a suitable temperature before rushing out the door. Waiting for the food to cool down is not only a waste of time but also disrupts their travel plans. Forcing themselves to eat the food directly after it has cooled slightly can easily burn their mouth and esophagus, and long-term consumption of hot food can also lead to esophageal cancer. As for porridge for infants, because infants are small and more sensitive to temperature, cooked porridge needs to be cooled directly by blowing air or using water. This also takes a long time and can easily lead to an increase in the number of microorganisms due to prolonged exposure, which can affect the health of infants. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a wind-cooled electric slow cooker that can cool down food when it is ready to eat, so that the food can quickly reach an edible temperature.
[0005] To solve the above technical problems, the following technical solution is adopted:
[0006] A wind-cooled electric slow cooker includes an outer shell, a heating device, a heat-conducting pot body, an inner pot, and a top cover. The heating device is located at the middle of the bottom of the inner wall of the outer shell. The heat-conducting pot body is placed inside the outer shell and covers the opening of the outer shell, with the bottom wall of the heat-conducting pot body in contact with the heating device. The inner pot is placed inside the heat-conducting pot body, and the top cover is placed over the opening of the inner pot. The slow cooker is characterized by further including a cooling fan, which is installed on the side wall of the outer shell, and the air outlet of the cooling fan is directed towards the heat-conducting pot body. A first annular cavity is formed between the heat-conducting pot body and the outer shell. At least one set of heat dissipation holes is opened on the side wall or bottom of the outer shell, and the set of heat dissipation holes is located away from the cooling fan. The set of heat dissipation holes includes at least one heat dissipation hole.
[0007] In the aforementioned air-cooled electric slow cooker, the heating element heats the inner pot through the heat-conducting pot body during stewing. When the food in the pot is ready to be eaten, the cooling fan can be turned on for cooling. When the cooling fan is working, the airflow enters the first annular cavity, flows around the first annular cavity, and then blows out from the heat dissipation holes, thereby quickly cooling the heat-conducting pot body and allowing the heat-conducting pot body to carry away the heat from the inner pot through heat transfer, thus cooling the food in the inner pot. This air-cooled electric slow cooker can cool food when it is ready to be eaten, allowing it to quickly reach an edible temperature. For cooling baby porridge, rapid air cooling can be achieved without opening the lid, which can effectively cool the baby porridge while preventing the growth of microorganisms due to prolonged exposure, thus benefiting the baby's health. Typically, the outer shell also has an operation panel for controlling the operation of the heating element and the cooling fan, which is located on the front of the outer shell.
[0008] In a preferred embodiment, the cooling fan is disposed on the rear side wall of the housing.
[0009] In a preferred embodiment, at least two heat exchange hole groups are formed on the side wall of the heat-conducting pot body. The two heat exchange hole groups are staggered, and each heat exchange hole group includes at least one heat exchange hole. The inner pot is placed inside the heat-conducting pot body and covers the opening of the heat-conducting pot body, forming a second annular cavity between the inner pot and the heat-conducting pot body. By forming heat exchange holes on the heat-conducting pot body, when the cooling fan blows air, some of the airflow can enter the second annular cavity through one of the heat exchange hole groups to directly cool the inner pot. After carrying away the heat, the airflow enters the first annular cavity through the other heat exchange hole group, flows along the first annular cavity, and then dissipates through the heat dissipation holes. Compared to simply cooling the heat-conducting pot body, this method can further improve the cooling effect and effectively shorten the cooling time. Typically, to maximize the space inside the inner pot, the outer wall of the inner pot is close to the inner wall of the heat-conducting pot body. Therefore, the space in the second annular cavity is small, and the airflow can also flow quickly within the second annular space to carry away heat.
[0010] In a further preferred embodiment, one of the heat exchange hole groups corresponds to the air outlet of the cooling fan. With this arrangement, the airflow blown out by the cooling fan can directly enter the second annular cavity through the heat exchange hole group, ensuring the incoming airflow.
[0011] In a further preferred embodiment, an air guide plate is also provided on the inner wall of the outer shell, and the air guide plate is disposed between the cooling fan and the heat-conducting pot body. The air guide plate directs more airflow towards the air inlet, allowing the airflow to be blown into the second annular cavity through the air inlet.
[0012] In a further preferred embodiment, the air guide plate is arranged around the upper half of the outer periphery of the cooling fan. With this arrangement, the airflow blown from the upper half of the cooling fan can be concentrated and blown into the second annular cavity through the air inlet, while part of the airflow blown from the lower half can flow along the first annular cavity, thereby simultaneously cooling the heat-conducting pot body and the inner pot, and promptly dissipating the heat.
[0013] In a further preferred embodiment, the two heat exchange hole groups are arranged facing each other. After entering the second annular cavity from one heat exchange hole group, the airflow can flow along the side wall of the inner pot from both sides, and finally enter the first annular cavity through the opposing heat exchange hole groups.
[0014] In a further preferred embodiment, the number of heat dissipation hole groups is two, with the two groups respectively located on the left and right sides of the outer casing sidewall. With this arrangement, regardless of whether the airflow is blown directly from the cooling fan into the first annular cavity or blown into the second annular cavity and then re-entering the first annular cavity, the airflow can be ensured to circulate around the first annular cavity, further improving the cooling effect.
[0015] In a preferred embodiment, the outer casing includes a base and an annular shell, with the upper edge of the base connected to the lower edge of the annular shell, and the heating device disposed in the base; the heat dissipation hole group disposed at the bottom of the outer casing is located at the protruding edge of the base. Typically, during the molding process, the base and the annular shell are injection molded separately and then assembled; the heat dissipation hole group is disposed on the base, allowing airflow to be discharged from below through the heat dissipation holes during cooling.
[0016] In a preferred embodiment, the heat-conducting pot body is made of metal, and the inner pot is made of ceramic.
[0017] The beneficial effect of this utility model is that this air-cooled electric slow cooker can cool down food when it is ready to eat, so that the food can quickly reach an edible temperature. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0026] Example 1, such as Figure 1-6 The illustrated air-cooled electric slow cooker includes an outer shell 1, a heating device 2, a heat-conducting pot body 3, an inner pot 4, a top cover 5, and a cooling fan 6. The heating device 2 is located in the middle of the bottom of the inner wall of the outer shell 1. The heat-conducting pot body 3 is located inside the outer shell 1 and covers the opening of the outer shell 1. The bottom wall of the heat-conducting pot body 3 is in contact with the heating device 2. The inner pot 4 is placed in the heat-conducting pot body 3, and the top cover 5 is placed over the opening of the inner pot 4. The cooling fan 6 is installed on the rear side wall of the outer shell 1, and the air outlet of the cooling fan 6 is directed towards the heat-conducting pot body 3. A first annular cavity 7 is formed between the heat-conducting pot body 3 and the outer shell 1. Two heat dissipation hole groups 101 are opened on the side wall of the outer shell 1. The two heat dissipation hole groups 101 are respectively located on the left and right sides of the side wall of the outer shell 1, and the heat dissipation hole groups 101 include multiple heat dissipation holes.
[0027] In the aforementioned air-cooled electric slow cooker, the heating device 2 heats the inner pot 4 through the heat-conducting pot body 3 during stewing. When the food in the pot is ready to be eaten, the cooling fan 6 can be turned on for cooling. When the cooling fan 6 is working, the airflow can enter the first annular cavity 7, flow around the first annular cavity 7, and then be blown out from the heat dissipation hole group 101, thereby quickly cooling the heat-conducting pot body 3 and allowing the heat-conducting pot body 3 to carry away the heat from the inner pot 4 through heat transfer, thus cooling the food in the inner pot 4. This air-cooled electric slow cooker can cool the food when it is ready to be eaten, so that the food can quickly reach an edible temperature. For cooling baby porridge, rapid air cooling can be performed without opening the top lid, which can effectively cool the baby porridge while preventing the growth of microorganisms due to prolonged exposure, which is beneficial to the baby's health. The outer shell 1 is also equipped with an operation panel for controlling the operation of the heating device 2 and the cooling fan 6, and the operation panel is located on the front side of the outer shell 1.
[0028] Two heat exchange hole groups 301 are formed on the side wall of the heat-conducting pot body 3. The two heat exchange hole groups 301 are arranged facing each other, and one of the heat exchange hole groups 301 corresponds to the air outlet of the cooling fan 6. The heat exchange hole group 301 includes multiple heat exchange holes. The inner pot 4 is placed in the heat-conducting pot body 3 and covers the opening of the heat-conducting pot body 3. A second annular cavity 8 is formed between the inner pot 4 and the heat-conducting pot body 3. By forming heat exchange holes on the heat-conducting pot body 3, the airflow blown out from the cooling fan 6 can directly enter the second annular cavity 8 through the heat exchange hole group 301. The airflow can flow along the side wall of the inner pot 4 from both sides, directly cooling the inner pot 4. After carrying away the heat, it enters the first annular cavity 7 through the opposing heat exchange hole group 301, and then flows along the first annular cavity 7 before dissipating from the heat dissipation holes. Compared with simply cooling the heat-conducting pot body 3, this method can further improve the cooling effect and effectively shorten the cooling time. In order to maximize the space of the inner pot 4, the outer wall of the inner pot 4 is close to the inner wall of the heat-conducting pot body 3. Therefore, the space of the second annular cavity 8 is small, and the airflow can also flow quickly in the second annular space 8 to carry away the heat.
[0029] An air guide plate 9 is also provided on the inner wall of the outer shell 1. The air guide plate 9 surrounds the upper part of the cooling fan 6 and is located between the cooling fan 6 and the heat-conducting pot body 3. The airflow blown from the upper part of the cooling fan 6 can be concentrated and blown into the second annular cavity 8 through the air inlet, while part of the airflow blown from the lower part can flow along the first annular cavity 7, thereby simultaneously cooling the heat-conducting pot body 3 and the inner pot 4 and timely dissipating the heat.
[0030] The heat-conducting pot body 3 is made of metal, and the inner pot 4 is made of ceramic.
[0031] Example 2, the difference between this example and Example 1 is as follows: Figure 7 As shown, the outer casing 1' includes a base 102' and an annular shell 103'. The upper edge of the base 102' is connected to the lower edge of the annular shell 103'. The heating device 2' is disposed in the base 102'. There are multiple heat dissipation hole groups 101', some of which are opened on the side wall of the annular shell 103' and some of which are opened on the protruding edge of the base 102'. During the molding process, the outer casing 1' is formed by injection molding the base 102' and then assembling them. The heat dissipation hole groups 101' are disposed on the base 102', so that airflow can be discharged from below through the heat dissipation holes during cooling.
