Description

Technical Field

[0001] The invention relates to the field of household electrical appliances, in particular to an electric pressure cooker. Background Art

[0002] Electric pressure cookers provide a high-pressure environment so that food can be cooked quickly in a high-temperature environment. This saves cooking time and improves the taste of food. However, after the food is cooked in a high-temperature and high-pressure environment, the pressure must be released before the lid can be opened. Since a high-temperature environment must be maintained during the cooking process, the cooling process is generally slow after cooking, and the waiting time for opening the lid is long. Based on this, the rapid cooling of electric pressure cookers is generally achieved through the water-cooling pressure reduction method, but there will be problems with the large size of the pot and the noise it is prone to. Summary of the invention

[0005] The above scheme provides a pot cooling component, by arranging the heat dissipation ring outside the pot, and then the cold end of the thermoelectric cooling sheet is in contact with the pot, and the hot end of the thermoelectric cooling sheet is in contact with the heat dissipation ring. Therefore, during use, the heat in the pot can be quickly absorbed by the cold ends of the multiple thermoelectric cooling sheets distributed in the circumferential direction, and then transferred to the hot ends of each thermoelectric cooling sheet, and then the heat is quickly diffused into the air after the heat dissipation area is expanded by the heat dissipation ring, so as to achieve the effect of rapid cooling. Since the heat dissipation ring is arranged outside the pot, the thermoelectric cooling sheet is located between the pot and the heat dissipation ring, and there is no need to set up other heat exchange pipelines or other complex structures, so the overall volume is controlled. Moreover, the heat dissipation process is realized by using the thermoelectric cooling sheet and the heat dissipation ring, and there will be no noise.

[0008] In one of the embodiments, the annular cold end is in contact with the side wall of the inner pot, and the annular hot end is in contact with the heat dissipation ring.

[0009] In one of the embodiments, a plurality of thermoelectric cooling sheets are evenly spaced and distributed in a circumferential direction of the pot.

[0012] The above scheme provides an electric pressure cooker, which, by adopting the pot cooling assembly described in any of the above embodiments, can achieve rapid cooling while controlling the volume of the pot body without generating noise. A heat dissipation air inlet hole is further provided on the bottom wall of the pot body, and a heat dissipation air outlet hole is further provided on the side wall of the pot body, so that the air in the pot body can circulate, further improving the heat dissipation efficiency of the heat dissipation ring and reducing the cooling time.

[0013] In one embodiment, the heat dissipation air outlet is located above the heat dissipation ring.

[0014] In one of the embodiments, there are multiple heat dissipation air inlet holes and multiple heat dissipation air outlet holes, multiple heat dissipation air inlet holes are distributed circumferentially on the bottom wall of the pot body, and multiple heat dissipation air outlet holes are distributed circumferentially on the side wall of the pot body.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The various technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the various technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] like Figure 1 and Figure 2As shown, in one embodiment, a pot cooling assembly 10 is provided, comprising a pot 11, a heat sink ring 12, and a plurality of thermoelectric cooling sheets 13. The heat sink ring 12 is sleeved outside the side wall of the pot 11, the thermoelectric cooling sheet 13 is located between the side wall of the pot 11 and the heat sink ring 12, the cold end 132 of the thermoelectric cooling sheet 13 is in contact with the side wall of the pot 11, the hot end 131 of the thermoelectric cooling sheet 13 is in contact with the heat sink ring 12, and the plurality of thermoelectric cooling sheets 13 are sequentially distributed in the circumferential direction of the pot 11.

[0028] During use, the heat in the pot 11 can be quickly absorbed by the cold ends 132 of the multiple thermoelectric cooling sheets 13 distributed in the circumferential direction, and then transferred to the hot ends 131 of each thermoelectric cooling sheet 13, and then the heat is quickly diffused into the air after the heat dissipation area is expanded by the heat dissipation ring 12, thereby achieving a rapid cooling effect. Since the heat dissipation ring 12 is sleeved outside the pot 11, the thermoelectric cooling sheet 13 is located between the pot 11 and the heat dissipation ring 12, and no other heat exchange pipelines or other complex structures are required, thereby controlling the overall volume. Moreover, the heat dissipation process is realized by using the thermoelectric cooling sheet 13 and the heat dissipation ring 12, and no power parts or liquid circulation pipelines are required, and there will be no noise.

[0029] In order to further improve the uniformity of heat dissipation of the inner pot 11, Figure 2 As shown, a plurality of thermoelectric cooling sheets 13 can be evenly spaced and distributed around the inner pot 11, so that the efficiency of heat transfer from each part of the inner pot 11 is more consistent.

[0030] Or, in one embodiment, Figure 1 As shown, a plurality of thermoelectric cooling sheets 13 are closely arranged along the side wall of the inner pot 11 to form a thermoelectric cooling ring. The annular cold end of the thermoelectric cooling ring contacts the inner pot 11 , and the annular hot end of the thermoelectric cooling ring contacts the heat dissipation ring 12 .

[0031] That is, the thermoelectric cooling ring can surround the inner pot 11 for a circle, realize the heat conduction process of the inner pot 11, and improve the heat dissipation effect. After the annular cold end absorbs the heat in the inner pot 11, it conducts it to the annular hot end, and then the heat dissipation ring 12 diffuses the heat of the annular hot end into the air, achieving the purpose of rapid cooling.

[0032] Specifically, the contact between the thermoelectric cooling sheet 13 and the inner pot 11 can be direct contact or indirect contact. For example, a heat conducting ring can be further provided outside the inner pot 11, and the heat conducting ring is located between the cold end 132 of the thermoelectric cooling sheet 13 and the inner pot 11, so as to quickly conduct the heat in the inner pot 11 to the cold end 132. In this way, when the inner pot 11 is taken out, friction between the inner pot 11 and the cold end 132 of the thermoelectric cooling sheet 13 can be avoided, which can prevent the effect of the thermoelectric cooling sheet 13 from being affected.

[0033] When the thermoelectric cooling sheet 13 is in direct contact with the inner pot 11 , in order to improve the heat dissipation effect, the cold end 132 of the thermoelectric cooling sheet 13 may be attached to the inner pot 11 , and the hot end 131 of the thermoelectric cooling sheet 13 may be attached to the heat dissipation ring 12 .

[0034] When a plurality of electric heating and cooling sheets form the electric heating and cooling ring, the annular cold end is in contact with the side wall of the pot 11 , and the annular hot end is in contact with the heat dissipation ring 12 .

[0035] Specifically, the heat dissipation ring 12 is a part that can quickly conduct heat away, and can be made of a material with a high thermal conductivity such as aluminum alloy. For example, the heat dissipation ring 12 can be an aluminum alloy ring.

[0036] Furthermore, in one embodiment, when a plurality of electric heating and cooling sheets constitute the electric heating and cooling ring, the heat conductive ring (not shown in the figure) is located between the annular cold end and the inner pot 11, the inner side of the heat conductive ring is in contact with the side wall of the inner pot 11, and the outer side of the heat conductive ring is in contact with the annular cold end, so as to further improve the heat absorption efficiency in the inner pot 11 and improve the overall heat dissipation effect.

[0037] Furthermore, in one embodiment, heat dissipation patterns may be further provided on the outer side of the heat dissipation ring 12 , thereby increasing the heat dissipation area of ​​the surface of the heat dissipation ring 12 and improving the heat dissipation effect.

[0038] Specifically, the heat dissipation pattern may be spiral-shaped, and the heat dissipation pattern is arranged in an axial spiral along the heat dissipation ring 12 .

[0039] Or, optionally, the heat dissipation lines may also be strip-shaped and distributed axially along the heat dissipation ring 12 .

[0040] Furthermore, if Figures 3 to 7As shown, in another embodiment, an electric pressure cooker 20 is provided, including a pot body 21 and the above-mentioned pot body cooling assembly 10, the pot body 21 is provided with a accommodating cavity with an opening, the pot body cooling assembly 10 is located in the accommodating cavity, the bottom wall of the pot body 21 is provided with a heat dissipation air inlet hole 211, and the side wall of the pot body 21 is provided with a heat dissipation air outlet hole 212.

[0041] By adopting the pot cooling assembly 10 described in any of the above embodiments, the volume of the pot body 21 is controlled while achieving rapid cooling without generating noise. A heat dissipation air inlet 211 is further provided on the bottom wall of the pot body 21, and a heat dissipation air outlet 212 is further provided on the side wall of the pot body 21, so that the air in the pot body 21 can circulate, further improving the heat dissipation efficiency of the heat dissipation ring 12 and reducing the cooling time.

[0042] Specifically, if Figures 4 to 7 As shown, the shapes of the heat dissipation air inlet hole 211 and the heat dissipation air outlet hole 212 can be circular or square, and no specific limitation is made here.

[0043] Further, in one embodiment, if Figure 3 As shown, the heat dissipation air outlet 212 is located above the heat dissipation ring 12. That is, the air entering from the heat dissipation air inlet 211 on the bottom wall of the pot body 21 passes through the heat dissipation ring 12 and is discharged from the heat dissipation air outlet 212 above the heat dissipation ring 12 to achieve the purpose of heat dissipation.

[0044] Furthermore, in order to improve the heat dissipation effect, as Figures 3 to 7 As shown, in one embodiment, there are multiple heat dissipation air inlet holes 211 and multiple heat dissipation air outlet holes 212, multiple heat dissipation air inlet holes 211 are circumferentially distributed on the bottom wall of the pot body 21, and multiple heat dissipation air outlet holes 212 are circumferentially distributed on the side wall of the pot body 21. Thus, the air circulation in the pot body 21 is improved.

[0045] Furthermore, in one embodiment, the heat dissipation ring 12 is spaced apart from the pot body 21 to form a ventilation cavity, and the heat dissipation air inlet hole 211 is located on the bottom wall of the pot body 21 at a position opposite to the ventilation cavity, so that the air entering from the heat dissipation air inlet hole 211 can just enter the ventilation cavity.

[0046] The air outlet direction of the heat dissipation air inlet hole 211 is inclined along the circumferential direction of the bottom wall of the pot body 21, so that the air entering from the heat dissipation air inlet hole 211 spirals upward in the ventilation cavity, extending the path of the air in the ventilation cavity and improving the heat dissipation effect of the heat dissipation ring 12.

[0047] Furthermore, in one embodiment, when the air outlet direction of the heat dissipation air inlet 211 is arranged along the circumferential tilt of the bottom wall of the pot body 21, and the side wall of the heat dissipation ring 12 opposite to the pot body 21 is provided with heat dissipation lines, the heat dissipation lines are spiral, and the heat dissipation lines are arranged along the circumferential spiral of the heat dissipation ring 12. The air entering from the heat dissipation air inlet 211 can effectively contact the heat dissipation lines on the heat dissipation ring 12 during the process of spiral rise. On the one hand, the contact area is large, and on the other hand, the heat dissipation lines can provide a guiding effect for the air spiral advance process, further improving the heat dissipation effect.

[0048] Furthermore, if Figure 3 , Figure 6 and Figure 7 As shown, the electric pressure cooker 20 further includes a pot cover 22, which is arranged on the opening of the pot body 21, and is provided with an exhaust valve 221 and a handle 222. The exhaust valve 221 is mainly used to stabilize the pressure in the pot of the electric pressure cooker 20 during cooking, and the handle 222 facilitates opening the pot cover 22.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
