[0025] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0026] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0027] like Figure 1-4 As shown, an evaporator according to an embodiment of the utility model includes an evaporator body 1 and a distribution plate 2.

[0028] The evaporator body 1 comprises a shell 11 and a heating component 12 . The shell 11 is surrounded by a first cavity, which is a steam generating cavity.

[0029] The shell 11 is provided with a water inlet joint 111 and a steam joint 112 communicating with the first cavity. The heating component 12 is connected to the shell 11 and heats the shell 11 .

[0030] The distribution plate 2 is arranged in the first cavity corresponding to the water inlet joint 111, and the distribution plate 2 and the shell 11 jointly surround a second cavity. The distribution plate 2 is provided with multiple leakage holes 211 connecting the first cavity and the second cavity, and the diameter of each leakage hole 211 is smaller than the diameter of the water inlet joint 111.

[0031] The incoming water enters the first cavity through the water inlet joint 111, the second cavity and the plurality of leakage holes 211 to generate steam and is discharged through the steam joint 112. Since the incoming water enters the first cavity through the plurality of leakage holes 211, the incoming water is distributed more evenly, thereby avoiding the phenomenon of uneven hot and cold at the front and rear ends of the evaporator.

[0032] For example, the number of the leakage holes 211 is 50-100, the diameter of the leakage holes 211 is between half and one third of the diameter of the water inlet joint 111, and the plurality of leakage holes 211 are evenly distributed.

[0033] Of course, the number and diameter parameters of the leakage holes 211 are not limited to the above-mentioned embodiments, and those skilled in the art can select the number and diameter parameters of the leakage holes 211 according to actual needs.

[0034] like Figure 2-4 As shown, in a preferred embodiment of the utility model, the position of the leakage hole 21 is staggered with the water inlet joint 111. When the water flows into the distribution plate 2 from the water inlet joint 111, the water first hits the wall of the distribution plate 2, causing the water to flow around, and then flows into the first cavity through the leakage hole 21, thereby realizing the redistribution of the water inlet position.

[0035] In a preferred embodiment of the present invention, Figure 2 As shown, Figure 2 A is the cold end side of the heating component 12, and B is the hot end side of the heating component 12. The distribution plate 2 is located directly above the hot end B of the heating component 12, so that the water inlet route between the water inlet and the hot end B is shorter than the water inlet route between the water inlet and the cold end A, thereby adjusting the temperature difference between the hot and cold ends of the evaporator and achieving a uniform hot and cold effect at the front and rear ends of the evaporator.

[0036] like Figure 2-4 As shown, in a preferred embodiment of the present invention, the distribution plate 2 includes a bottom wall 21 and an annular side wall 22 .

[0037] The lower end of the annular side wall 22 is fixedly connected to the bottom wall 21 , and the upper end of the annular side wall 22 is fixedly connected to the inner wall of the shell 11 . The second cavity is formed by the bottom wall 21 , the annular side wall 22 and the shell 11 , and the leakage hole 211 is located on the bottom wall 21 .

[0038] like Figure 2-4As shown, in a preferred embodiment of the utility model, an annular outer flange 221 is provided at the upper end of the annular side wall 22, and the annular outer flange 221 is sealed and fixed to the inner wall of the shell 11. The annular outer flange 221 has the effect of increasing the connection area with the inner wall of the shell 11, thereby improving the connection sealing and the connection structure strength.

[0039] For example, the annular outer flange 221 is sealed and welded to the inner wall of the housing 11 .

[0040] like Figure 2 As shown, in a preferred embodiment of the present utility model, the housing 11 includes an upper housing 113 and a lower housing 114, and the upper housing 113 and the lower housing 114 are sealed and snap-fitted together.

[0041] The first cavity is formed by the upper shell 113 and the lower shell 114 , and the second cavity is formed by the upper shell 113 and the distribution plate 2 .

[0042] The water inlet joint 111 and the steam joint 112 are both located on the upper shell 113. In a preferred embodiment of the present invention, the water inlet joint 111 and the steam joint 112 can be detachably mounted on the upper shell 113.

[0043] like Figure 2 As shown, in a preferred embodiment of the present invention, the heating component 12 includes a heating tube 121 and a heat transfer plate 122 .

[0044] The heating tube 121 is connected to a power line via a positive terminal 1211 and a negative terminal 1212 .

[0045] The upper end surface of the heat transfer plate 122 abuts against the lower end surface of the lower shell 114, and the heating tube 121 abuts against the lower end surface of the heat transfer plate 122. The heat transfer plate 122 transfers the heat of the heating tube 121 to the lower shell 114. The lower end wall of the lower shell 114 is the bottom wall of the first cavity. When the water flow of the leakage hole 211 contacts the high-temperature bottom wall of the first cavity, steam is generated.

[0046] The number of the heating tubes 121 is one or more, and those skilled in the art can select the number of the heating tubes 121 according to actual needs.

[0047] like Figure 2 As shown, in a preferred embodiment of the present invention, the shape of the heat transfer plate 122 is matched with the bottom surface shape of the lower shell 114 .

[0048] like Figure 2 As shown, in a preferred embodiment of the present invention, the heating tube 121 is U-shaped.

[0049] Of course, the heating tube 121 is not limited to being in a U shape, and may also be in a straight shape, a ring shape, or a spiral shape. Those skilled in the art may select the shape of the heating tube according to actual needs.

[0050] In a preferred embodiment of the present invention, a temperature sensor is further included. The temperature sensor is installed on the heat transfer plate 122 or the lower shell 114. The temperature sensor is electrically connected to the controller of the kitchen equipment to detect the temperature of the evaporator to avoid measuring the evaporator temperature being too high or too low.

[0051] The utility model also provides a kitchen device, comprising the above evaporator.

[0052] When the kitchen appliance is a dishwasher, the evaporator on the dishwasher is used to generate steam to sterilize the tableware.

[0053] When the kitchen appliance is a steam oven, the evaporator on the steam oven is used to steam the food.

[0054] Since the kitchen device of the utility model includes the above-mentioned evaporator, more uniform water distribution is achieved, thereby avoiding the phenomenon of uneven hot and cold at the front and rear ends of the evaporator.
