Abstract
The utility model discloses an internal structure of an electric switching valve. The internal structure of the electric switching structure comprises a base and a rotor located on the base, an opening is formed at the top of the base, an air inlet and air outlets are arranged in the base, magnetic steel is arranged outside the rotor in a sleeved mode, and the bottom end of the rotor stretches into the base and a flow regulating switch for adjusting flow of the air outlets is arranged at the bottom end of the rotor. The internal structure of the electric switching structure is characterized in that a lower clamping plate preventing the refrigerant ejected from the air inlet from directly contacting with the magnetic steel surface. Compared with the prior art, the internal structure of the electric switching structure has the advantages that through additional arrangement of the lower clamping plate on the internal structure of the electric switching structure, not only can the refrigerant ejected from the air inlet be prevented from directly contacting with the magnetic steel surface, but also the refrigerant ejected from the air inlet can be rebounded through the lower clamping plate so as to flow out of the air outlets more evenly.
Description
Technical field
The utility model relates to a kind of dynamoelectric switching valve, specifically refers to a kind of internal structure of dynamoelectric switching valve.
Background technique
Refrigerator temperature control often all needs to use dynamoelectric switching valve, by the rotation angle of accurate control dynamoelectric switching valve rotor, realizes connecting assembly control refrigeration agent output quantity.The internal structure of existing dynamoelectric switching valve is all similar, generally all include base and rotor, in base, be provided with suction port and air outlet, refrigeration agent enters base inside from suction port, and from the air outlet outflow, outside rotor, being arranged with magnet steel, the rotor bottom is stretched in the base, and in order to regulate the output quantity of refrigeration agent, between rotor bottom and base, be provided with the flow control valve that adjusts the gas port flow.The defective of existing this dynamoelectric switching valve is: the refrigeration agent that goes out from tuned port injection can directly contact with the magnet steel face, and sprays the bounce-back point owing to not existing in base inside, thereby makes the air outlet flow also even inadequately.For fear of producing this defective, people have designed a kind of new dynamoelectric switching valve structure, it sprays the bounce-back point one of base processing, the refrigeration agent that goes out from tuned port injection flows to the air outlet through this injection bounce-back point, but, after base increases injection bounce-back point, can make product structure become complicated, and the cost of increase product, thereby be still waiting to be further improved.
The model utility content
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, provide a kind of simple in structure, can effectively protect the magnet steel face and make the internal structure of the uniform dynamoelectric switching valve of air outlet flow.
The utility model solves the problems of the technologies described above the technological scheme that adopts: the internal structure of this dynamoelectric switching valve, comprise base and the rotor that is positioned at the base top, described base top forms opening, base inside is provided with suction port and air outlet, described rotor is arranged with magnet steel outward, the rotor bottom is stretched into and is provided with the flow control valve of regulating described air outlet flow in the base and in the rotor bottom, it is characterized in that: be provided with the die holder that prevents from directly touching from the refrigeration agent of air outlet ejection the magnet steel face at described base.
Preferably, described magnet steel is provided with a rotor cover outward, described die holder by clamping between the end face of the bottom of this rotor cover and described base.Like this, the fixed structure of die holder is just comparatively firm.
Further preferred, described die holder is ring, and the toroidal surface of die holder is fixed between rotor cover bottom and the base top surface, and the bottom of described rotor is stretched in the described base after passing the center hole of die holder.
Described flow control valve can have multiple structural type, and preferably, described flow control valve is one to be fixed on the rotor bottom and to keep the switch pad that rotates synchronously with rotor.
For refrigeration agent can be flowed out from the air outlet equably, described suction port is one, and described air outlet is two, and the position of suction port is higher than the position of air outlet.Like this, the refrigeration agent that goes out from tuned port injection is after the die holder reflection, and based on the principle that flowing water flows from high to low, refrigeration agent can flow out from two air outlets equably naturally.
Compared with prior art, advantage of the present utility model is: by setting up the die holder in the internal structure of dynamoelectric switching valve, both can prevent from directly contacting with the magnet steel face from the refrigeration agent that tuned port injection goes out, and can make again from the refrigeration agent of suction port ejection and after die holder forms bounce-back, flow out from the air outlet more equably.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the internal structure of the dynamoelectric switching valve of present embodiment comprises parts such as base 1, rotor 2, magnet steel 3, die holder 4, rotor cover 5, switch pad 6 and supporting base 10.
Wherein, opening is formed on base 1 top, and suction tude is installed on the base, and the suction port at suction tude 7 tops is positioned at base 1 inside.The bottom of base 1 also is formed with opening, and supporting base 10 sealing is installed on this bottom opening, and first steam outlet pipe 8 and second steam outlet pipe 9 are installed on the supporting base 10, and first air outlet and second air outlet all are opened on supporting base 10 end faces.
Die holder 4 is ring, and the toroidal surface of die holder 4 is fixed on rotor and overlaps between 5 bottoms and base 1 end face, thereby makes that the fixed structure of die holder 4 is comparatively firm.After die holder 4 is set, the refrigeration agent that goes out from tuned port injection directly flows out from first air outlet and second air outlet after die holder 4 bounce-backs, thereby can prevent refrigeration agent and magnet steel face, particularly directly contact with the magnet steel bottom surface, and then prolong the working life of dynamoelectric switching valve.In addition, because the position of first air outlet and second air outlet all is lower than the position of suction port, based on the principle that flowing water flows from high to low, can be more equably from first air outlet and the outflow of second air outlet after die holder 4 bounce-backs from the refrigeration agent of suction port ejection.
The center hole that die holder 4 is passed in the bottom of rotor 2 stretches in the base 1, fixedly has in the bottom of rotor 2 with rotor 2 to keep the switch pad 6 of rotation synchronously.Because switch pad 6 is close to mutually with the end face of supporting base 10, and first air outlet and second air outlet all be opened on supporting base 10 end faces, thereby during the rotation of switch pad, the area that each air outlet is covered can change, and regulates the refrigeration agent output quantity with this.In addition, in the present embodiment, this dynamoelectric switching valve also includes support 14, mounting plate 15 and motor housing 16, because these parts do not belong to the internal structure of dynamoelectric switching valve, thereby its concrete structure is not described in detail in the present embodiment.
The above only is preferred implementation of the present utility model; should be understood that; for those of ordinary skills; do not breaking away under the principle prerequisite of the present utility model; can make multiple remodeling or improvement to the utility model, be not limited to two such as the air outlet of base, also can be one, three or four; thereby make the open and close of output control can reach 2 to 16 patterns etc., these all are regarded as within the protection domain of the present utility model.
