Description
Technical field
The present invention relates to Humidity Detection technical field, more particularly to the humidity detector of a kind of dryer and dry
Clothing machine.
Background technology
The operation principle of dryer Humidity Detection is：Two mutually isolated bonding jumpers as negative electrode and anode,
When clothing contacts two electrodes simultaneously, the resistance value that is able to detect that between two electrodes, the moisture content of clothing is not
Together, resistance value is also different.The clothing of same component, resistance value increase with the moisture content reduction of clothing,
Therefore, the dry and wet degree of clothing can be judged by the size of resistance value.
Two electrodes of existing dryer are arranged in the front support of roller.Dryer mainly relies on roller
In rotation process, clothing drop after with two electrodes while contacting, detect the resistance between two electrodes.But
It is because front support and cylinder bottom have certain height distance, and to be fixed on around nozzle, only work as clothing
Thing is stacked into certain altitude, or during positioned at stack shell front end, could be contacted with two electrodes of front support position.Such as
Fruit clothes amount is less, possibly can not be stacked into the height of electrode at front support, can only be dropped wink by clothing
Between contacted with electrode, this reduces the time that clothing contacts with electrode, if clothing will not fall when dropping
Fall in stack shell front end, then cause clothing can not be contacted with two electrodes.Therefore, the peace of electrode in the prior art
Holding position, data acquisition is unstable when clothes amount will be caused less, easily causes controller and judges to be forbidden
Really, drying effect is poor.

Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Referring to Figures 1 and 2, present embodiment protects a kind of humidity detector of dryer, the Humidity Detection
Device includes metal stack shell 1, and insulating mounting has sheet metal 2, and metal stack shell 1 on the inwall of metal stack shell 1
Two electrodes of humidity detector are used separately as with sheet metal 2.
The humidity detector of the dryer, sheet metal 2 and metal stack shell 1 are set respectively as two isolation
Electrode, be located at due to sheet metal 2 on the inwall of metal stack shell 1, two electrodes are set compared with the prior art
The scheme in the front support apart from cylinder bottom certain distance is put, the clothing in the dryer, it is not necessary to accumulate
Contact of the clothing simultaneously with sheet metal 2 and metal stack shell 1 can be realized to corresponding height, therefore, when
When a small amount of clothing is dried, it can realize that clothing is stably connected with sheet metal 2 and metal stack shell 1.
Further, because an electrode of the prior art fixation is located at one end of stack shell, laundry amounts are few
When, it may not drop at the electrode, it is possible to cause controller to judge that clothing is dry, cause to do
Clothing effect is bad, and in order to prevent above phenomenon from occurring, sheet metal 2 in the embodiment is along metal stack shell 1
Axial direction distribution, by increasing capacitance it is possible to increase the probability that clothing contacts after dropping with sheet metal 2.When sheet metal 2 is along stack shell
The length of axial direction is with the axial length phase of stack shell meanwhile, it is capable to ensure what clothing contacted after dropping with sheet metal 2
Probability reaches 100%, can ensure the accuracy of Humidity Detection.The specific size and dimension of the sheet metal 2 is not
Limit.
Specifically, as shown in figure 1, the inwall of metal stack shell 1, which is provided with plastics, dials leaf 3, plastics are dialled on leaf 3
Sheet metal 2 is installed.The insulation that the plastics are dialled leaf 3 and can played between metal stack shell 1 and sheet metal 2 is made
With.And the effect of plastics group leaf 3 is to be used to clothing lifting arriving eminence, therefore, plastics are dialled leaf 3 and can protected
Demonstrate,prove contact of the sheet metal 2 with clothing.In addition, it is the block knot of plastics that the plastics in present embodiment, which dial leaf 3,
Structure, rather than supporting structure, block structure have the characteristics of firm, stable.
Preferably, plastics are dialled leaf 3 and are distributed along the axial direction of metal stack shell 1.The work(of lifting clothing can be improved
Can, moreover it is possible to improve the probability with contact with clothing.The length direction that plastics dial leaf 3 can be with metal stack shell 1
It is axially in parallel, can also be at an angle, plastics, which dial leaf 3, can realize the probability improved with contact with clothing
.
In present embodiment, sheet metal 2 is coated on plastics and dialled on leaf 3, and this kind of mode enables sheet metal 2
Enough to be in close contact with plastics group leaf 3, Stability Analysis of Structures is firm, simultaneously, moreover it is possible to the gold for preventing other forms from fixing
Category piece 2 causes to damage to clothing.
Above-mentioned sheet metal 2 and metal stack shell 1 will be connected with controller, judge the He of sheet metal 2 by controller
Whether resistance value reaches preset value corresponding to drying between metal stack shell 1.Signal is passed into control in order to realize
Device processed, insulating mounting has metal friction bar 4 on the outer wall of metal stack shell 1, specifically, as shown in Fig. 2 gold
Belong to circumference of the fricting strip 4 along the metal stack shell 1 and be coiled into close ring, metal friction bar 4 and metal stack shell 1
Between be provided with insulation board 5, metallic connection parts 6, metal are connected between metal friction bar 4 and sheet metal 2
Fricting strip 4 contacts with the first carbon brush 7, and the outer wall of metal stack shell 1 contacts with the second carbon brush 8.Data-signal
Control is issued by the conduction of metallic connection parts 6, metal friction bar 4, the first carbon brush 7 and the second carbon brush 8
Device.Gradually reduced by the continuous upset of clothing, the increase of drying time, the moisture content of clothing, work as resistance
When value reaches preset value, controller judges that clothing has reached dry state, and control clothes drying process terminates.
Metallic connection parts 6 are located in plastics and dialled in leaf 3, and metal stack shell 1 and insulation board 5 are provided with and supply metal
The through hole that connecting portion 6 passes through, the through hole on metal stack shell 1 should ensure that metallic connection parts 6 can not be with metal cylinder
Body 1 contacts, and to prevent turning on therebetween, can not normally be detected.
Metallic connection parts 6 in the embodiment can turn on sheet metal 2 and metal friction bar 4, gold
Category connecting portion 6 can select for metallic plate or wire, can be selected as the case may be.
The present invention also protects a kind of dryer, and the dryer has the humidity detector of above-mentioned dryer.
The drying of the clothing of varying number can be applied to, and can guarantee that drying effect, can solve the problem that conventional dryer
Judge the shortcomings that inaccurate when drying a small amount of clothing.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain this
The principle of invention, and limiting the scope of the invention can not be construed in any way.Based on herein
Explain, those skilled in the art would not require any inventive effort the other tools that can associate the present invention
Body embodiment, these modes are fallen within protection scope of the present invention.
