The present utility model provides a drainage structure 100 and a cooking appliance 1000, which can drain condensed water in a cooking cavity 220, and can form a steam sealing structure through a drainage channel 20, so as to ensure air tightness of the cooking cavity 220 during operation.
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.
As shown in fig. 1 to 8, the drainage structure 100 according to the embodiment of the present utility model can be used for draining the cooking cavity 220.
Wherein the water drain structure 100 comprises a water tower 10, the water tower 10 is suitable for being installed on the bottom wall 210 of the cooking cavity 220, and is provided with a water drain channel 20, the width dimension of an opening of at least one part of the water drain channel 20 in the water drain direction is not more than 5 mm, the water drain channel is used for draining the cooking cavity 220 and is suitable for being closed by water to form a steam seal structure, and the arrangement is that the condensed water in the cooking cavity 220 can be drained through the water drain structure 100, and meanwhile, a sealing steam structure can be formed to ensure the airtight seal of the cooking cavity 220.
Specifically, when the cooking appliance 1000 is operated, high-temperature steam can be released in the cooking cavity 220 to cook, steam and bake in the cooking cavity 220, and when the high-temperature steam contacts with the wall surface of the cooking cavity 220, the high-temperature steam can form condensed water on the wall surface of the cooking cavity 220 due to relatively low temperature of the wall surface of the cooking cavity 220, the condensed water can flow to the bottom wall 210 of the cooking cavity 220 under the action of gravity and the pressure of the high-temperature steam, and water is discharged through the water tower 10 arranged on the bottom wall 210 of the cooking cavity 220, so that the condensed water can be discharged through the water discharge channel 20, and the use experience of a user is improved.
Meanwhile, the water tower 10 is provided with the drain passage 20, and the opening width dimension of at least a portion of the drain passage 20 in the drain direction may be not more than 5 mm, for example, the opening width dimension of at least a portion of the drain passage 20 may be 2 mm, 3 mm, etc., so that condensed water may form a steam sealing structure in the drain passage 20 during passing through the drain passage 20, preventing high temperature steam in the cooking cavity 220 from being discharged through the drain structure 100, to ensure the working stability of the cooking cavity 220.
Here, at least a portion of the drain passage 20 in the drain direction means that the drain passage 20 is divided into a plurality of stages in the drain direction (refer to the up-down direction in fig. 1), wherein at least one stage is the at least a portion. The width dimension means a width in one direction or any direction perpendicular to the drainage direction. Wherein the at least a portion of the drain channel 20 may have an opening or a plurality of openings, and wherein the width dimension of each opening is no greater than 5 millimeters when there are a plurality of openings. The opening may be a circular opening, a bar-shaped opening, or the like, and for example, the opening is a straight line-shaped opening, an arc line-shaped opening, a broken line-shaped opening, an elliptical opening, or the like. The present utility model is mainly described as the drainage channel 20 is divided into a plurality of sections in the drainage direction, each section has an opening, and the openings of the plurality of sections are sequentially connected to form the channel, but this is not a limitation of the protection scope of the present utility model.
In addition, a plurality of water drainage channels 20 may be disposed in the water tower 10, and the opening width of at least a portion of the plurality of water drainage channels 20 is not greater than 5 mm, so that the water drainage efficiency of the water drainage structure 100 may be improved, and a steam sealing structure may be formed in the plurality of water drainage channels 20, so as to improve the air tightness of the cooking cavity 220, and ensure the normal operation of the cooking cavity 220.
Therefore, according to the drainage structure 100 of the embodiment of the present utility model, condensed water in the cooking cavity 220 can be drained, and a sealing water film can be formed by the drainage, so that the air tightness of the cooking cavity 220 is ensured when in operation.
As shown in fig. 5, in some embodiments of the utility model, the drain channel 20 may include a first portion 41 and a second portion 42.
Wherein, the first portion 41 and the second portion 42 are sequentially arranged and connected in the drainage direction of the drainage channel 20, the opening width dimension of the first portion 41 is not more than 5 mm, so that condensed water can form a steam sealing structure in the first portion 41 to ensure the air tightness of the cooking cavity 220, and the opening width dimension of the first portion 41 is smaller than the opening width dimension of the second portion 42, thus being convenient for residues to pass through the drainage channel 20.
When the cooking apparatus 1000 works, high temperature steam can be generated in the cooking cavity 220 to steam and bake food in the cooking cavity 220, and condensed water generated by the high temperature steam can be discharged through the drainage structure 100, in the process, part of food residues can fall on the bottom wall 210 of the cooking cavity 220 and flow to the water tower 10 through the flow entrainment of the condensed water, and finally be discharged through the drainage channel 20, if in the drainage direction of the drainage channel 20, the second part 42 and the first part 41 are connected in sequence, and since the opening width dimension of the first part 41 is smaller than the opening width dimension of the second part 42, the food residues entrained by the condensed water can accumulate in the drainage channel 20, so that the drainage channel 20 is blocked, and therefore, the first part 41 and the second part 42 can be connected in sequence along the drainage direction, so that the food residues can be discharged through the drainage channel 20.
Of course, the first portion 41 of the drain passage 20 may include a plurality of first portions 41 and second portions 42 which may be sequentially arranged and connected in a drain direction, and it is understood that the plurality of first portions 41 may have condensed water passing therethrough and may be converged in the second portion 42 during the drain of the drain passage 20, and then may be passed through the second portion 42 to achieve the drain of the condensed water, thereby improving the drain efficiency of the drain structure 100, and forming a steam sealing structure in the plurality of first portions 41 to improve the airtight performance of the cooking cavity 220.
As shown in fig. 5, in some embodiments of the present utility model, the first portion 41 and the second portion 42 may meet in the up-down direction, in other words, the drain passage 20 may extend in the up-down direction, so that condensed water passing through the drain passage 20 may be discharged under the effect of gravity.
Wherein, the up-down direction can be the same as the drainage direction.
In addition, a stepped surface 43 is connected between the inner circumferential surface of the first portion 41 and the inner circumferential surface of the second portion 42, and the inner circumferential edge of the stepped surface 43 is connected to the first portion 41, and the outer circumferential edge of the stepped surface 43 is connected to the second portion 42, it is understood that a discontinuous transition surface is formed between the inner circumferential surface of the first portion 41 and the inner circumferential surface of the second portion 42 by the stepped surface 43, specifically, when condensate water forms a vapor seal structure in the first portion 41, due to cohesive force between liquid molecules of the condensate water, the effect of gravity is overcome, so that the condensate water can hang on the inner circumference of the stepped surface 43, in other words, the condensate water can be held in the first portion 41 to form the vapor seal structure. In order to be better understood, it is assumed that there is a transition surface connected between the inner circumferential surface of the first portion 41 and the inner circumferential surface of the second portion 42, which may provide a guiding effect for the condensed water in the first portion 41 so that the condensed water flows toward the second portion 42 along the transition surface, and it is difficult to form a steam sealing structure at the first portion 41, which is disadvantageous in protecting the air tightness of the cooking cavity 220.
Further, the stepped surface 43 may have a ring shape to uniformly stress the condensed water held in the first portion 41, and a steam sealing structure may be better formed to secure the air tightness of the cooking cavity 220.
Secondly, the ratio of the length dimension of the first portion 41 to the length dimension of the drain passage 20 is not greater than 0.5, which facilitates the passage of food waste through the drain passage 20, and it is understood that by reducing the ratio of the length dimension of the first portion 41 to the length dimension of the drain passage 20, the passage of food waste through the drain passage 20 is facilitated, for example, when food waste is caught in the first portion 41, the food waste can be pushed in the drain direction, and since the opening width dimension of the second portion 42 is not smaller than the opening width dimension of the first portion 41, the food waste can be smoothly drained along the drain passage 20 when leaving the first portion 41, thereby avoiding clogging of the food waste.
Of course, the ratio of the length dimension of the first portion 41 to the length dimension of the drain passage 20 may be greater than 0.5 mm, e.g., 0.7 mm, 0.8 mm, etc., to increase the ratio of the first portion 41 to the drain passage 20, so that the size of the steam sealing structure may be increased to provide a better sealing effect for the cooking cavity 220.
As shown in fig. 4 and 5, in some embodiments of the present utility model, the opening width dimension of at least a portion of the drain channel 20 is in the range of 0.3 mm to 3 mm; specifically, an opening width dimension of at least a portion of the drain passage 20 may be not less than 0.3 mm so that condensed water may drain through the drain passage 20; the opening width dimension of at least a portion of the drain passage 20 may be not more than 3 mm to enhance the forming effect of the steam sealing structure, thereby ensuring the airtight performance in the cooking cavity 220.
As shown in fig. 1 to 7, in other embodiments of the present utility model, at least a portion of the drain passage 20 in the drain direction is opened to have a circular hole with an inner diameter of not more than 5 mm, wherein condensed water may form a steam sealing structure in at least a portion of the drain passage 20, and the condensed water may be uniformly stressed in the at least a portion, so that the condensed water may better maintain the steam sealing structure in the drain passage 20 to ensure the air tightness of the cooking cavity 220.
As shown in fig. 4 and 5, in some embodiments of the present utility model, the inlet 21 of the drainage channel 20 is provided on the bottom surface of the water tower 10, specifically, after flowing in the water tower 10, the condensed water enters the drainage channel 20 through the inlet, so as to prolong the flowing time of the condensed water in the drainage structure 100 to play a role of buffering and prevent the condensed water from impacting the formed steam sealing structure, wherein the bottom surface of the water tower 10 is configured as a slope gradually inclining downwards from the periphery to the inlet 21, and it is understood that the bottom surface of the water tower 10 has a diversion effect, so that the condensed water can be conveniently discharged, in other words, the condensed water can flow along the bottom surface of the water tower 10 under the action of gravity after flowing into the water tower 10, and flow from the periphery of the bottom surface to the inlet 21 of the drainage channel 20 under the guiding effect of the bottom surface, so as to enter the drainage channel 20, and realize the drainage of the condensed water.
In other embodiments, the inlet 21 of the drain passage 20 may be provided in the middle region of the bottom surface of the water tower 10, so that the condensed water in the water tower 10 may uniformly flow to the inlet 21 of the drain passage 20, thereby facilitating the formation of a steam sealing structure in the drain passage 20.
