Summary of the invention
The object of the present invention is to provide a kind of simple and reasonable, volume is little, the automatic water-replenishing device of safe and reliable, easy and simple to handle, electric steamer that cost is low, to overcome weak point of the prior art.
Press the automatic water-replenishing device of a kind of electric steamer of this purpose design, comprise the electric steamer body, body is provided with storage tank and water leg, water leg communicated with evaporator tank on being arranged on heat-generating disc by communicating pipe, its architectural feature is to be provided with a thimble push-press type water injecting mechanism between storage tank and the water leg, this water injecting mechanism is dismountable to be arranged on the storage tank water inlet, and corresponding setting has the precompressed boss on the water leg.
Above-mentioned water injecting mechanism comprises the water inlet flap that matches with the storage tank water inlet, and water inlet flap middle part is provided with one and connects cavity, is provided with a thimble in the cavity, and the thimble afterbody is provided with a limited step that matches with water leg roof pressure boss; Be provided with a location boss in the cavity, be provided with back-moving spring between this positioning boss and the thimble limited step; The thimble front end stretches out into that the part of water flap is provided with a seal cover, and the lower limb gland of seal cover covers edge at water inlet.The thimble front end stretches out the positioning step that the part of water flap into is provided with the fixing seal lid, and seal cover is fastened on the positioning step by the locating hole that its middle part is provided with.The lower end that connects cavity is socketed on the water leg on the roof pressure boss, connects between cavity and the roof pressure boss and is provided with water space.The lower surface that connects cavity is lower than the water leg top end face.Water inlet flap and storage tank water inlet junction are provided with sealing ring.Join by screw thread or buckle structure between water inlet flap and the storage tank water inlet.
When the present invention uses, will fill with water in the storage tank earlier, cover connects thimble push-press type water injecting mechanism then, and the seal cover of this mechanism is under the effect of back-moving spring, and gland covers edge at water inlet, and when preventing the storage tank reversing, water flows out automatically; After the storage tank reversing of filling with behind the water, put into electric steamer, the roof pressure boss crimping mutually on the thimble push-press type water injecting mechanism of storage tank and the water leg, the roof pressure boss heads into thimble in the storage tank, and the seal cover disengaging water inlet that joins with thimble covers edge; Owing to connect between cavity and the roof pressure boss and be provided with water space, the water in the storage tank enters in the water leg under the perforation cavity flow of water inlet flap; Because water leg communicated with evaporator tank on being arranged on heat-generating disc by communicating pipe, the height of water level in the water leg is exactly the interior height of water level of evaporator tank.
In the time of incipient, water leg height of water level interior and that evaporator tank is interior is all lower, air enters in the storage tank by crossing water space, water in the storage tank flows in water leg and the evaporator tank gradually, when the water level of water leg arrived or surpass the lower surface that connects cavity, storage tank formed water seal, at this moment, because atmospheric effect, the water of storage tank no longer continue to flow out; Water level in water leg and evaporator tank drops to when being lower than the lower surface that connects cavity, and water seal is destroyed, and air enters in the storage tank by crossing water space, and the water in the storage tank continues to flow out, and replenishes the evaporation of water leg and evaporator tank internal cause and the moisture of loss.Like this, go round and begin again the water automatic water supplement under water seal and atmospheric effect in the storage tank.
The present invention utilizes the principle of linker and water seal to carry out moisturizing control automatically in water leg and evaporator tank, can reach the purpose of automatic water supplement at any time; The present invention also can be widely used in Electric heating food steamer, micro-wave oven etc. and need carry out in the family cooking equipment of automatic water supplement.
Storage tank water inlet among the present invention is meant that water enters the inlet of water leg from storage tank, and this water inlet also can be the inlet that water is injected storage tank; If for the real needs of user or design, also water can be injected the inlet and the water of storage tank and separate mutually from the inlet that storage tank enters water leg, be provided with separately, the independent setting of these two inlets does not influence purpose of the present invention.
The present invention is simple and reasonable, volume is little, safe and reliable, easy and simple to handle, cost is low.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1-Fig. 4, the automatic water-replenishing device of this electric steamer, the electric steamer body, body is provided with storage tank 1 and water leg 2, water leg 2 communicated with evaporator tank on being arranged on heat-generating disc 3 by communicating pipe 4, be provided with a thimble push-press type water injecting mechanism between storage tank and the water leg, this water injecting mechanism is dismountable to be arranged on storage tank 1 water inlet, and corresponding setting has roof pressure boss 21 on the water leg 2.Water injecting mechanism comprises the water inlet flap 111 that matches with storage tank 1 water inlet, and water inlet flap 111 is provided with sealing ring 115 with storage tank 1 water inlet junction, joins by screw thread or buckle structure between water inlet flap 111 and storage tank 1 water inlet.Water inlet flap 111 middle parts are provided with one and connect cavity, are provided with a thimble 113 in the cavity, and thimble 113 afterbodys are provided with a limited step that matches with water leg 2 roof pressure boss 21; Be provided with a location boss in the cavity, be provided with back-moving spring 112 between this positioning boss and thimble 113 limited steps; Thimble 113 front ends stretch out the positioning step that the part of water flap 111 into is provided with fixing seal lid 114, and seal cover 114 is fastened on the positioning step by the locating hole that its middle part is provided with.The lower limb gland of seal cover 114 is in water inlet flap 111 upper edge.The lower end that water inlet flap 111 connects cavity is socketed on the water leg 2 roof pressure boss 21, connects between cavity and the roof pressure boss and is provided with water space.The lower surface 116 that connects cavity is lower than water leg 2 top end faces.
