In order to avoid the first heating device 400, the two second coupling members 230 are disposed to deviate from the central portion of the outer pot, and at this time, in order to avoid that the second coupling members 230 cannot be aligned with the first coupling members 110 smoothly due to circumferential shaking occurring when the outer pot 200 is placed, the protective cover 700 in this embodiment is provided with a positioning boss 710 protruding downwards, the positioning boss 710 is formed by partially sinking or protruding downwards the bottom wall of the protective cover 700, the bottom plate 121 is provided with a positioning slot 1211, the positioning boss 710 and the positioning slot 1211 are both arranged deviating from the center of the outer pot 200, the positioning boss 710 is inserted into the positioning slot 1211, and the design is such that, the outer pot 200 can be circumferentially positioned by the cooperation of the positioning bosses 710 and the positioning grooves 1211, so that the second coupling member 230 can be coupled with the first coupling member 110 in a quick alignment manner, thereby avoiding the occurrence of the situation that the outer pot 200 needs to be aligned for multiple times due to circumferential shaking when being placed in the casing 100.
It can be understood that in other embodiments of the present invention, a part of the bottom plate is arched upwards to form a positioning boss, a part of the bottom wall of the protective cover is arched upwards to form a positioning groove, the positioning boss and the positioning groove are arranged deviating from the center of the outer pot, and the positioning boss is inserted into the positioning groove.
It can be understood that in other embodiments of the utility model, the sidewall of the outer pot is provided with a vertically extending strip-shaped groove, and the limiting rib is inserted into the limiting groove and is in sliding fit with the limiting groove.
Example two
As shown in fig. 7, compared with the first embodiment, the present embodiment is different in that the bottom wall of the outer pot 200 in the present embodiment is provided with an installation groove 240 formed by being depressed upward, the water storage tank 600 is formed between the side wall of the installation groove 240 and the side wall of the outer pot, the first heating device 400 is fixed on the bottom wall of the installation groove 240, and the second heating device 500 is arranged outside the bottom wall of the water storage tank 600. By the design, the sealing element can be omitted, so that the risk of water leakage is reduced.
While the utility model has been described with reference to specific embodiments thereof, it will be understood by those skilled in the art that the utility model is not limited thereto, and may be embodied in many different forms without departing from the spirit and scope of the utility model as set forth in the following claims. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
