Abstract
The utility model provides a four-grade temp.-regulating electric under blanket, which comprises a blanket surface, a resistance wire, conducting wires, and a control switch assembly. The middle part of the resistance wire is provided with a tap, and three conducting wires are respectively led out from both ends of the resistance wire and the tap and are connected with the control switch assembly; the control switch assembly comprises a series-parallel converting switch and a power control switch. The utility model has the advantages of simple structure and low cost; the multi-grade temperature regulation can be carried out, and the heating temperature of the resistance wire can be effectively controlled to adopt different environmental temperature and the different temperature required by difference people.
Description
The utility model relates to a kind of daily living article, particularly a kind of under blanket with four-shift temp.-regulating function.
The under blanket that present people generally use is divided into basically: " not temperature-adjusting type " (it is superseded to have become) and " temperature-adjusting type " two kinds, and their actual functional capability exists significant disadvantages:
1. the function of " not temperature-adjusting type " under blanket only limits to the bed clothes of heating before sleeping for people, want powered-down before falling asleep, otherwise under blanket is persistently overheating, the people is born can't stand.But, after closing several hours,, tend to the people is frozen awake again if indoor temperature is lower, need turn on the power switch again and heat, so just making sleep lose continuity, cold sleep environment when hot when adding is unfavorable for people's health.
2. common " temperature-adjusting type " under blanket, low temperature shelves only are to adopt diode rectification to reduce the power of resistance wire, and the temperature adjustment amplitude is little.Even switch is transferred to the low temperature shelves, the heating power of its resistance wire is also at more than 70% of high temperature shelves, and it is overheated still to seem, long-time use can make the people produce discomfort.
In sum, because the temperature of existing under blanket can not be effectively controlled, so it is in use not only inconvenient, and in case carelessness (as forgetting powered-down after getting up), very easily breaking out of fire accident brings harm for people's life and property.
Though minority top grade (luxurious) under blanket temperature adjusting performance is better, because of its circuit devcie complex structure, manufactures the cost height, so its price is difficult to most consumers and accepts.
The purpose of this utility model provides a kind of simple in structure, and cost is low, thus can many grades the effective novel four-shift temp.-regulating under blanket of controlling resistance silk heating temps of temperature adjustment.
The purpose of this utility model is achieved in that it comprises cotton-padded mattress face, resistance wire, lead and control switch group, it is characterized in that: the middle part of resistance wire is provided with tap, resistance wire two ends and tap are respectively drawn a lead and are linked to each other with the control switch group, and the control switch group comprises connection in series-parallel conversion and two switches of diode halfwave rectifier power control.
The utility model utilizes tap that resistance wire is divided into two sections, the resistance wire two ends link to each other with the control switch group by lead respectively with tap, two sections resistance wires can be worked with the series and parallel dual mode under the parallel-series switch effect of control switch group, thereby can realize effectively being rapidly heated (two sections resistance wires are with parallel way work) and long-time insulation (two sections resistance wires are with series system work).Simultaneously, utilize the diode halfwave rectifier power control switching of control switch group can make " intensification " and " insulation " shelves respectively be divided into two grades of " height ", " low ".So promptly form " intensification-Gao ", " heating up-low ", " insulation-Gao ", " insulation-low " totally four control shelves, thereby can make under blanket adapt to the different temperatures needs of people it.
Fig. 1 is a circuit diagram of the present utility model.
Fig. 2 is the utility model overall appearance schematic diagram.
Fig. 3 is the utility model control switch group schematic appearance.
As shown in the figure, it comprises cotton-padded mattress face 4, resistance wire 5, lead 3 and four parts of control switch group, and the middle part of resistance wire 5 is provided with tap 6, and the two ends of resistance wire 5 link to each other with the control switch group by lead 3 respectively with tap 6; The control switch group is made up of parallel-series switch 2 and diode halfwave rectifier power control switching 1 two parts, and diode halfwave rectifier power control switching 1 is divided into " high and low, pass " third gear.
When using the utility model, under blanket is linked to each other with civil power.Its each gear engaged situation is as follows:
" intensification-Gao " shelves: diode halfwave rectifier power control switching 1 is put " height " position, parallel-series switch 2 is put " intensification " position, this moment, two sections resistance wires were state in parallel, resistance is little, and be not connected in series diode, directly connect utility grid, this moment power maximum (100%), it is the fastest to heat up.
Shelves " heat up-low ": diode halfwave rectifier power control switching 1 is put " low " position, and parallel-series switch 2 is put " intensification " position, and this moment, two sections resistance wires still were state in parallel, resistance is little, but be connected in series diode between utility grid, power this moment big (being about 70%), it is slower to heat up.(cold especially in room temperature, as to wish when warm that these shelves can be as " insulation " the most high-grade use).
" insulation-Gao " shelves: diode halfwave rectifier power control switching 1 is put " height " position, parallel-series switch 2 is put " insulation " position, this moment, two sections resistance wires were series connection, resistance is big, be not connected in series diode, directly connect utility grid, this moment, power less (being about 25%) can keep warm slightly temperature for a long time.
" insulation-low " shelves: diode halfwave rectifier power control switching 1 is put " low " position, parallel-series switch 2 is put " insulation " position, this moment, two sections resistance wires were series connection, resistance is big, and serial connection diode, this moment, power minimum (being about 17%) can make under blanket keep little warm temperature for a long time.
