Description
Technical field
The utility model relates to pump technology field, especially relates to a kind of silencing water pump and uses the water warming blanket of this silencing water pump.
Background technique
Water warming blanket is that the one of carrying out based on all drawbacks such as insecurity of electric blanket improves product, and it has the plurality of advantages such as safety, constant temperature, electromagnetic-radiation-free, non-inductive voltage, temperature be easy to adjust.Because for sleep, water warming blanket has strict demand to quiet and hot water circuit.
Water warming blanket is generally made up of main frame and blanket body two-part, and as shown in Figure 1, main frame comprises heater, aqua storage tank and recycle pump, its function be exactly water is heated to setting temperature and be recycled to inside blanket body.The control temperature of main frame is generally below 65 DEG C, and recycle pump is centrifugal brushless direct-current water pump, and recycle pump the hot water press-in water warming blanket pipe one end in aqua storage tank, and flows out from the water warming blanket pipe the other end, reaches the effect that cycling hot exchanges.
But, water through heating particularly to more than 40 DEG C after, under the high velocity effect of circulating pump impeller, the air be dissolved in water is easy to the formation bubble that is separated, because the resistance of water warming blanket pipe is comparatively large, flow velocity is comparatively slow, is gathered in bubble in the pump housing and is difficult to be discharged outside the pump housing.And the bubble be gathered in the pump housing can form several large harm to water warming blanket: 1, destroy vacuum, pump efficiency reduces, and produces the noise of " ", affect Consumer and sleeps; 2, water pump water force characteristic dies down, and when pipe hinders constant, flow velocity is slack-off, and in water warming blanket pipe, hot water circuit is not smooth; Because flow velocity is slack-off, cause wheel speed to improve, produce more bubble, form vicious circle; Mechanicalness noise also becomes large.
Model utility content
The purpose of this utility model is the defect overcoming prior art, a kind of silencing water pump and water warming blanket are provided, by setting up a rising pipe in pump chamber, namely water outlet number is increased, to improve the flow velocity of water pump water outlet end water, thus effectively by external for the bubble excavationg pump be gathered in the pump housing, to reduce the use noise of water pump and corresponding water warming blanket, reach good muting function.
For achieving the above object, the utility model proposes following technological scheme: a kind of silencing water pump, comprise the lid below the pump housing and the described pump housing, cavity is formed in the described pump housing, described lid is provided with water intake and main water outlet, in described cavity, is provided with the auxiliary waterexit mouth communicated with described water intake.
Another object of the present utility model is also to provide a kind of water warming blanket, comprise heater, aqua storage tank, water pump and blanket body, described water pump comprises the lid below the pump housing and the described pump housing, cavity is formed in the described pump housing, described lid is provided with water intake and main water outlet, the auxiliary waterexit mouth communicated with described water intake is provided with in described cavity, described water intake is all communicated with described aqua storage tank with auxiliary waterexit mouth, is respectively used to be sent in the described pump housing by the hot water in aqua storage tank and be used for a part of hydraulic pressure in the described pump housing to return described aqua storage tank; Described main water outlet is connected with described blanket body one end, and the described blanket body the other end accesses described heater.
Further, in the described pump housing, impeller is installed.
Preferably, the diameter of described main water outlet is greater than the diameter of described auxiliary waterexit mouth.
The beneficial effects of the utility model are: the utility model improves the flow velocity at pump housing waterexit end place, substantially the generation of bubble in the pump housing can be suppressed, and the bubble of generation can be discharged smoothly from water pump, thus improve the working efficiency of water pump, there is preferably muting function simultaneously.

Embodiment
Below in conjunction with accompanying drawing of the present utility model, clear, complete description is carried out to the technological scheme of the utility model embodiment.
As shown in Figure 2, a kind of silencing water pump that the utility model discloses, comprises the lid 2 below the pump housing 1 and the pump housing 1, lid 2 is provided with water intake 3 and main water outlet 4, and water intake 3 is for being drawn in the pump housing 1 by the water outside the pump housing 1; The existing pump housing 1 generally arranges a water outlet, namely only has an exhalant canal, and easily produce the problem of larger noise for existing this water pump, the utility model makes Optimal improvements on this architecture basics, sets up a rising pipe.
Particularly, be formed with cavity in the pump housing, extend upward another road rising pipe from the upper end of water intake 3 in the pump housing 1, the upper end of the rising pipe extended is auxiliary waterexit mouth 5, and the water pump after namely improving has two water outlets.
In addition, impeller 6 is installed in water pump, under the rotation of impeller 6, as shown in Figure 3, water outside the pump housing 1 is drawn in the pump housing 1 from water intake, is then mainly discharged to the pump housing from main water outlet 4, and the bubble produced in drainage procedure is upwards discharged from auxiliary waterexit mouth 5 automatically.
Preferably, the diameter of auxiliary waterexit mouth 5 is less than the diameter of main water outlet 4, can ensure water out in the pump housing 1 like this, mainly discharge outside the pump housing 1 through main water outlet 4, to ensure the sufficient with water of this water pump product of corresponding use; And sub-fraction water and the bubble be gathered in the pump housing 1 are discharged outside the pump housing 1 by auxiliary waterexit mouth 5.
The utility model further discloses a kind of water warming blanket using the water pump of above-mentioned introduction, and as shown in Figure 3, water warming blanket comprises heater, aqua storage tank, water pump and blanket body, and heater is for heating the water in aqua storage tank; The water intake of water pump connects aqua storage tank; Two water outlets of water pump, wherein, the main water outlet 4 outside the pump housing 1 connects blanket body one end, is pressed in blanket body by the water after heating; Auxiliary waterexit mouth 5 in the pump housing 1 connects aqua storage tank, for a part of hot water and the bubble be gathered in the pump housing 1 are pushed back aqua storage tank; Another termination heater of blanket body, heater, aqua storage tank, water pump and blanket body form hot water cyclesystem, reach the effect that cycling hot exchanges.
Use the water warming blanket after the utility model water pump, when not changing existing blanket body structure, the noise produced in its using process obtains obvious reduction.Certainly, water pump of the present utility model is not limited to and is applied on water warming blanket.
After the utility model sets up water outlet, improve the flow velocity of water pump water outlet end water, can be effectively external being gathered in bubble excavationg pump in the pump housing, thus reduce the noise of water pump; And due to the increase of flow velocity, the rotating speed of water pump has decline, further reduce the pump noise that rotating speed causes.
Technology contents of the present utility model and technical characteristics have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from the utility model spirit based on teaching of the present utility model and announcement; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present utility model and modification should be comprised, and contained by present patent application claim.
