[0037] The cooking appliance 10 of this utility model is described below with reference to the accompanying drawings.

[0038] like Figures 1-8 As shown, the cooking appliance 10 of this utility model embodiment includes a housing 100, a heat preservation cover 200, and a drain pipe 300.

[0039] The housing 100 is provided with a water collection tank 110, and the housing 100 has an openable or closable pot lid 130. The water collection tank 110 is used to collect condensation water generated when the pot lid 130 of the cooking appliance 10 is opened. A heat preservation cover 200 is disposed inside the housing 100, and the heat preservation cover 200 is used to keep the space inside the housing 100 warm, and its surface temperature is relatively high (usually above 100 degrees Celsius).

[0040] The drain pipe 300 has a first end 310 and a second end 320. The first end 310 of the drain pipe 300 is connected to the water collection tank 110, and the second end 320 of the drain pipe 300 is connected to the outside of the housing 100. The drain pipe 300 is thermally connected to the heat insulation cover 200 so as to use the heat of the heat insulation cover 200 to heat the water in the drain pipe 300.

[0041] The specific working process of the cooking appliance 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] When the cooking appliance 10 is turned on in this embodiment, the condensate produced falls into the water collection tank 110. The condensate in the water collection tank 110 collects and flows into the drain pipe 300 through the first end 310. Due to the thermal connection between the drain pipe 300 and the heat insulation cover 200, the temperature of the surface of the heat insulation cover 200 is conducted to the drain pipe 300, and then to the condensate inside, causing the condensate to heat up and evaporate to form water vapor. The heated water vapor is then discharged to the outside of the housing 100 through the drain pipe 300.

[0043] Compared with the prior art, in this embodiment of the cooking appliance 10, the water collection tank 110 inside the housing 100 is connected to the drain pipe 300, so that the condensate generated when the lid 130 of the cooking appliance 10 is opened can be collected by the water collection tank 110 and then flow into the drain pipe 300. The drain pipe 300 is thermally connected to the heat insulation cover 200 inside the housing 100, so that the condensate in the drain pipe 300 is heated to a steam state by the heat insulation cover 200, and the steam is then discharged from the drain pipe 300 to the outside of the housing 100. That is to say, since the steam formed after the condensate is heated is directly discharged to the outside of the housing 100 through the drain pipe 300, the condensate is prevented from flowing back into the housing 100 or spilling on the countertop where the cooking appliance 10 is placed. Furthermore, there is no need to use a water storage box to collect the condensate, saving users the operation steps of frequently cleaning the water storage box, thus improving the user experience.

[0044] In addition, the heat insulation cover 200 is used to heat the condensate in the drain pipe 300, thereby making full use of the heat of the heat insulation cover 200 and achieving the effect of saving energy.

[0045] The cooking appliance 10 of this utility model embodiment is an electric rice cooker. The outer shell 100 also houses a pot body 400 for holding food, and the lid 130 of the cooking appliance 10 covers the pot body 400. A water collection tank 110 is located below the lid 130 to collect condensate generated when the lid 130 is opened.

[0046] In some embodiments, such as Figure 3 As shown, the second end 320 of the drain pipe 300 is also connected to the water collection tank 110, and the first end 310 of the drain pipe 300 is also connected to the outside of the housing 100. Wherein, Figure 3 The solid arrows in the diagram represent the direction of condensate flow, while the dashed arrows represent the direction of water vapor flow.

[0047] In other words, the first end 310 of the drain pipe 300 is connected not only to the water collection tank 110, but also to the outside of the housing 100, so that the first end 310 of the drain pipe 300 can not only allow condensate from the water collection tank 110 to flow in, but also allow water vapor evaporated by heating in the drain pipe 300 to discharge through the first end 310. The second end 320 of the drain pipe 300 is connected not only to the outside of the housing 100, but also to the water collection tank 110, so that the second end 320 of the drain pipe 300 can not only allow condensate from the water collection tank 110 to flow in, but also allow water vapor evaporated by heating in the drain pipe 300 to discharge through the second end 320.

[0048] Furthermore, such as Figure 5 and Figure 6 As shown, both the first end 310 and the second end 320 of the drain pipe 300 are provided with a connecting pipe 340 that communicates with the outside of the housing 100. The connecting pipe 340 is horizontally or inclined, and the inlet of the connecting pipe 340 is lower than the outlet. That is, the first end 310 of the drain pipe 300 is connected to the outside through the connecting pipe 340, and the second end 320 of the drain pipe 300 is connected to the outside through the connecting pipe 340. Furthermore, because the connecting pipe 340 is horizontally or inclined, so that its outlet is higher than its inlet, the condensate entering the first end 310 or the second end 320 is not easily discharged from the outlet of the connecting pipe 340.

[0049] Specifically, the connecting pipe 340 includes a first pipe section 341 and a second pipe section 342. The second pipe section 342 extends vertically, with its upper end connected to the water collection tank 110 and its lower end connected to either the first end 310 or the second end 320 of the drain pipe 300. The first pipe section 341 extends horizontally and is connected to the second pipe section 342. The inlet of the first pipe section 341 is located on the inner wall of the second pipe section 342, and its outlet connects to the outer side of the housing 100.

[0050] In other words, the condensate in the water collection tank 110 flows into the first end 310 or the second end 320 of the drain pipe 300 through the upper end of the first pipe section 341, while the water vapor discharged through the first end 310 or the second end 320 of the drain pipe 300 is discharged to the outside of the shell 100 through the outlet of the first pipe section 341.

[0051] In other embodiments, such as Figure 4 As shown, the first end 310 of the drain pipe 300 is only connected to the water receiving tank, and the second end 320 is only connected to the outside of the housing 100. Among these, Figure 4 The solid arrows in the diagram represent the direction of condensate flow, while the dashed arrows represent the direction of water vapor flow.

[0052] The condensate in the water collection tank 110 is collected and flows into the drain pipe 300 through the first end 310. The water vapor formed by the evaporation of the condensate is discharged to the outside of the shell 100 through the second end 320 of the drain pipe 300.

[0053] In some embodiments, such as Figure 3 and Figure 4 As shown, the drain pipe 300 is wound around the insulation cover 200 at least once. That is, the drain pipe 300 can be wound around the insulation cover 200 one, two, three, or more times. By winding the drain pipe 300 around the insulation cover 200 a greater number of times, not only is the length of the drain pipe 300 extended, increasing the condensate storage capacity of the drain pipe 300 and ensuring that the condensate does not flow out of the drain pipe 300 before evaporation, but the contact area between the drain pipe 300 and the insulation cover 200 is also increased, improving the evaporation effect of the condensate.

[0054] In some embodiments, such as Figure 7 and Figure 8 As shown, the drain pipe 300 includes a water storage section 330, with both ends of the water storage section 330 being flush and higher than its lowest point. Because both ends of the water storage section 330 are higher than its lowest point, condensate that has not yet evaporated is preferentially stored at the lowest point of the water storage section 330, preventing it from flowing out from both ends. This ensures that the condensate does not easily flow out of the water storage section 330 before evaporation.

[0055] Furthermore, such as Figure 7 As shown, the first end 310 and the second end 320 of the drain pipe 300 are flush, and both the first end 310 and the second end 320 are higher than the rest of the drain pipe 300, so that the two ends of the water storage section 330 are the first end 310 and the second end 320, respectively. This further ensures that condensate will not flow out from the first end 310 or the second end 320 before evaporation, improving practicality.

[0056] In some embodiments, such as Figure 7 and Figure 8 As shown, the water storage section 330 of the drain pipe 300 in this embodiment of the present invention includes: a first section 331 and a second section 332.

[0057] The upper end of the first section 331 is the first end 310, and the lower end of the first section 331 is located at the lowest point of the drain pipe 300. The lower end of the second section 332 is connected to the lower end of the first section 331, and the upper end of the second section 332 is the second end 320. The first section 331 and / or the second section 332 are thermally connected to the insulation cover 200, so that the drain pipe 300 is thermally connected to the insulation cover 200. That is, the first section 331 is thermally connected to the insulation cover 200; or, the second section 332 is thermally connected to the insulation cover 200; or, both the first section 331 and the second section 332 are thermally connected to the insulation cover 200. This gives the water storage section 330 a larger contact area with the insulation cover 200, thereby improving the evaporation effect of condensate in the water storage section 330.

[0058] In some embodiments, such as Figure 7 and Figure 8 As shown, the second section 332 is spirally wound around the insulation cover 200 at least once, so that the drain pipe 300 is wound around the insulation cover 200 at least once. That is, the second section 332 can be spirally wound around the insulation cover 200 one, two, three, or more times. By making the second section 332 spirally wound around the insulation cover 200 a greater number of times, not only is the length of the second section 332 extended, increasing the condensate storage capacity within the second section 332, but the second section 332 is also evenly distributed vertically on the insulation cover 200, thereby improving the heat exchange effect between the second section 332 and the insulation cover 200, and further enhancing the evaporation effect of the condensate.

[0059] It should be noted that the number of turns of the drain pipe 300 around the insulation cover 200 needs to be determined according to the specific specifications of the cooking appliance 10, so it is not limited here.

[0060] In some embodiments, such as Figure 7As shown, the first section 331 extends vertically. This allows condensate to flow quickly to the bottom of the first section 331 after entering from the first end 310, and then flow into the second section 332, thereby improving the heat exchange efficiency of the condensate flowing in from the first end 310.

[0061] Optionally, the drain pipe 300 is made of aluminum. Because aluminum has good thermal conductivity, it improves the heat exchange efficiency between the drain pipe 300 and the insulation cover 200, thereby improving the evaporation efficiency of condensate in the drain pipe 300.

[0062] Alternatively, the drain pipe 300 can also be made of copper. Since copper has good thermal conductivity, it improves the heat exchange efficiency between the drain pipe 300 and the insulation cover 200, thereby increasing the evaporation efficiency of the condensate inside the drain pipe 300.

[0063] Alternatively, the drain pipe 300 can also be made of other thermally conductive materials with good thermal conductivity.

[0064] In some embodiments, the inner diameter of the drain pipe 300 is 2 mm to 5 mm. Optionally, the inner diameter of the drain pipe 300 is 2 mm to 5 mm. Optionally, the inner diameter of the drain pipe 300 is 2.5 mm to 4.5 mm. Optionally, the inner diameter of the drain pipe 300 is 3 mm to 4 mm. This not only ensures that there is sufficient space in the drain pipe 300 to store condensate, but also avoids the overall size of the drain pipe 300 being too large, which would result in a large overall size of the cooking appliance 10, thus reducing the space occupied by the cooking appliance 10 in this embodiment.

[0065] The inner diameter of the drain pipe 300 includes, but is not limited to, 2mm, 2.5mm, 3mm, 3.4mm, 4mm, 4.5mm or 5mm.

[0066] In some embodiments, where only the first end 310 is connected to the water collection tank 110, a vertically penetrating water inlet hole 111 is provided on the bottom wall of the water collection tank 110. The upper end of the first end 310 is connected to the water inlet hole 111.

[0067] In some other embodiments, when both the first end 310 and the second end 320 are connected to the water collection tank 110, two vertically penetrating water inlets 111 are provided on the bottom wall of the water collection tank 110. The upper end of the first end 310 is connected to one water inlet 111, and the upper end of the second end 320 is connected to one water inlet 111.

[0068] Furthermore, the inlet is a downward-facing constricted through-hole to facilitate the collection of condensate in the water collection tank 110 and its downward flow into the inlet.

[0069] In some embodiments, such as Figure 1As shown, the inner wall of the housing 100 is provided with multiple vent holes 120 extending to the outside of the housing 100. Each vent hole 120 corresponds to the outlet of the connecting pipe 340, and the diameter of each vent hole 120 is smaller than the outlet diameter of the connecting pipe 340. This allows water vapor discharged from the outlet of the connecting pipe 340 to be discharged to the outside of the housing 100 through the multiple vent holes 120. Furthermore, because the diameter of each vent hole 120 is smaller than the outlet diameter of the connecting pipe 340, it makes it difficult for foreign objects (such as insects) to enter the housing 100.

[0070] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
