Description
Technical field
The utility model belongs to refrigerating plant field, especially relates to a kind of ice layer thickness sensing control system of freezing equipmentSystem.
Background technology
At present, consumers in general wish that beverage or wine product can reach the effect of cooling, traditional ice at short noticeCase will reach the effect of cooling and last longer. Quick cooler can well meet this type of demand of user.
Quick cooler ice bucket the inside is full of after water, and refrigeration system starts, and starts Wang Tong center and freezes, if do not control from bucket wallWater in module bucket can be completely icing, and user is by not having space to place the iced article of needs such as alcoholic drink product, for user bringsDifficulty on certain use.
Utility model content
The purpose of this utility model is to provide a kind of ice layer thickness sensor and freezing equipment, by establishing at freezing equipmentPut ice layer thickness sensor and can well solve the problem that prior art exists, can be by the icing thickness control of freezing equipment bucket wallBuilt in the scope of needs.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of ice layer thickness sensor, comprises control panel, sonde configuration part, and described sonde configuration part is provided with pcb board, instituteState on pcb board and be provided with data acquisition module, sonde configuration part is provided with at least one probe, and this probe is exposed to sonde configurationPart outside, is connected with the data acquisition module signal of telecommunication.
Further: described digital sampling and processing front end input linking probe, rear end output is connected with wireOutput control signal.
Further: described control panel is connected with sonde configuration part by nut, between nut and sonde configuration partBe provided with pad and/or sealing ring.
Further: described sonde configuration part adopts technique and the probe of post forming one-body molded.
A kind of freezing equipment, comprises aforesaid ice layer thickness sensor.
Further: described ice layer thickness sensor and instant freezer bucket wall joint portion are provided with whippy packing ring,Installation can be fitted closely with bucket wall.
Ice layer thickness sensor described in the utility model is exposed to sonde configuration part outside; The direct contact refrigeration of probe is coldEquipment ice bucket air, water or ice, gather air, water or ice resistivity data, is connected with signal processing module by wire. ProbeBe placed on measured object the inside and contact with measured object (ice, water etc.), probe is applied to alternating current (or direct current), according to measured objectThe difference of (ice, water etc.) resistivity, the magnitude of voltage difference that digital sampling and processing collects, digital sampling and processing basisDifferent magnitudes of voltage judges that measured object is water or ice. Probe is titanium or other metal (as: stainless steel) material. This practicalityNovel described probe picking rate is fast, accuracy is high, and ice layer thickness sensor can identify air, water, three kinds of materials of ice,There is the function of controlling the icing thickness of ice sheet.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details.
Ice layer thickness sensor 100 as shown in Figure 3 comprises control panel 1, sonde configuration part 2, and described sonde configuration part is establishedBe equipped with pcb board, on described pcb board, be provided with data acquisition module, sonde configuration part 2 is provided with three probes 3, and this probe exposesIn sonde configuration part outside, be connected with the data acquisition module signal of telecommunication. Control panel 1 is connected with sonde configuration part by nut 4,Between nut 4 and sonde configuration part 2, be provided with pad 5 and sealing ring 6. Sonde configuration part 2 adopts technique and the spy of post formingPin 3 is one-body molded.
Digital sampling and processing front end input linking probe, rear end output is connected output control signal with wire.
The Circuits System of ice layer thickness sensor, as shown in Figure 2, probe directly contacts a barrel interior air, water or ice, collectsResistivity signal be input to digital sampling and processing and carry out identifying processing, defeated after then being differentiated by digital sampling and processingGo out a level signal control refrigeration system.
The detection principle of ice layer thickness sensor is: Figure 1 shows that detection principle equivalent circuit diagram, by the titanium of sensorGenus or other metal (as: stainless steel) probe are placed on measured object the inside and are connected step-down electricity with after measured object (ice, water etc.) contactHold C1 and commutation diode D1, and then meet filter capacitor C2; Adding to titanium or other metal (as: stainless steel) probe submitsStream voltage AC, R1 is the equivalent resistance of measured object, its equivalent schematic is as shown in Figure 1. Can distinguish between contact according to the value of V0Measured object be air, ice or water. Also can use direct current to be added on probe, but circuit need to make part amendment.
As shown in Figure 4, the present embodiment is arranged on ice layer thickness sensor 100 on the bucket wall 200 of ice bucket of quick cooler. FirstFirst from inside by sensor 100 through a bucket cinclides 201, then put rubber seal 6 and plastic pad 5 is finally locked plastic cement nut4. Wherein after installation rubber blanket can with bucket wall closely laminating to play waterproof anti-
The effect of leaking.
The concrete application process of the present embodiment is expressed as follows:
Shown in Fig. 2, three titaniums or other metal (as: stainless steel) probe wherein two be placed on icing terminated line301 and one or two be placed on after ice-out in release line 302. Wherein release line 302 after icing terminated line 301 and ice-outDistance bucket wall A and B respectively, concrete distance needs to determine according to application. User opens after quick cooler, titanium or other metal(as: stainless steel) probe gathers air, water or ice data in bucket, delivers to digital sampling and processing processing:
A. while start, close refrigeration system;
B. detection start line, terminated line 301 are all water, start refrigeration system;
C. detection start line, terminated line are all ice or air, close refrigeration system;
Aforementioned is preferred embodiment of the present utility model, not departing under the prerequisite of the utility model principle, all rightMake some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
