Description

Automatic defroster of freezer vent

Technical Field

The utility model belongs to the technical field of freezer equipment, more specifically the device that adopts the icing condition of contact sensor response to carry out automatic deicing to the freezer vent that says so.

Background

In the design of the traditional Chinese medicine material storage cold storage, the air in the cold storage needs to have proper circulation, so that the temperature of the air in each part of the cold storage is uniform. If air circulation is not carried out, the air in the storehouse absorbs the respiratory heat of the Chinese medicinal materials and the heat leakage of each part, so that the temperature of the upper layer is increased, and the Chinese medicinal material products are easy to deteriorate. Especially, in the short time of putting in storage of traditional chinese medicinal materials, more need strengthen the ventilation circulation of freezer, traditional freezer vent often can freeze when needing to ventilate, needs artifical deicing just can open the vent and ventilate.

Therefore, there is a need for an automatic deicing device for a vent of a refrigeration house.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problem that exists among the background art, the utility model provides an automatic defroster of freezer vent, the device's contact sensor is installed on the shutter, sends alarm switch volume when the sensor is covered by ice, gathers alarm switch volume through IO collection module and sends into control module, and control module drive heating copper pipe heats the shutter, plays the function of automatic deicing.

In order to achieve the above purpose, the utility model is realized by the following technical scheme:

a steel rail current collecting device is characterized in that: the automatic deicing device for the ventilation opening of the refrigeration house comprises a contact type sensor 1, a power supply module 2, an I/O acquisition module 3, a control module 4 and a heating copper pipe 5; the signal output end of the contact sensor 1 is connected with the signal input end of the I/O acquisition module 3, the signal output end of the I/O acquisition module 3 is connected with the signal input end of the control module 4, and the signal output end of the control module 4 is connected with the heating copper pipe; the power supply module 2 supplies power to the module needing power supply; the contact sensor (1) is arranged on a louver blade of the ventilation opening, and the heating copper pipe (5) is arranged on a connecting shaft of the ventilation opening.

Further, automatic defroster of freezer vent still include earth leakage protection switch 6, power module 2's input and earth leakage protection switch 6 link to each other.

The utility model discloses beneficial effect:

the utility model discloses a contact sensor gathers the frozen condition of vent, and when contact sensor was covered by ice, automatic alarm signal sent, rear end heating copper pipe self-heating vent had guaranteed the unblocked often of vent, and the vent freezes when having avoided needing to ventilate and needs artifical deicing, has practiced thrift manpower and materials.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-3, the automatic deicing device for the ventilation opening of the refrigeration house comprises a contact sensor 1, a power module 2, an I/O acquisition module 3, a control module 4 and a heating copper pipe 5; the contact type sensor 1 is arranged on a vent shutter, when the shutter is frozen, the surface of the contact type sensor 1 is frozen, the contact type sensor 1 sends an alarm signal at the moment, the signal output end of the contact type sensor 1 is connected with the signal input end of an I/O acquisition module 3, the I/O acquisition module 3 receives the alarm signal and transmits the alarm signal to a control module 4, the signal output end of the I/O acquisition module 3 is connected with the signal input end of the control module 4, the signal output end of the control module 4 is connected with a heating copper pipe, and the control module 4 drives the heating copper pipe to heat after receiving the alarm signal of the I/O acquisition module, so that the vent shutter automatically freezes; power module 2 provides electric power for the module that needs the power supply, can form rivers when making ice melt because of heating copper pipe 5 heating shutter, for avoiding rivers to lead to heating copper pipe 5 short circuits, causes the potential safety hazard, as preferred, installs earth leakage protection switch 6 additional before power module 2, and when rear end equipment short circuit electric leakage, earth leakage protection switch can automatic disconnection, avoids causing bigger potential safety hazard.

The utility model discloses a working process: the contact sensor 1 is arranged on a louver blade of the ventilation opening, and the heating copper pipe 5 is arranged on a connecting shaft of the ventilation opening. When the ice house normally operates, the shutter gradually freezes, the surface of the contact sensor 1 is gradually covered by ice, and when the contact sensor 1 is completely covered by ice, the contact sensor 1 sends out an alarm signal. Alarm signals are transmitted to the I/O acquisition module 3 through a lead, the contact of the I/O acquisition module 3 is closed, the alarm signals are continuously transmitted to the control module 4, the control module 4 drives the heating copper pipe 5 to automatically heat and deice when receiving the alarm signals, when the surface of the contact sensor 1 is frozen and melted, the alarm switching value is turned off, the contact of the I/O acquisition module 3 is turned off, the control module 4 stops driving the heating copper pipe 5 when not receiving the alarm signals, and the heating copper pipe 5 stops heating.

Finally, it is noted that the above preferred embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit, although the present invention has been described in detail through the above preferred embodiments, it should be understood by those skilled in the art that various changes in form and detail may be made thereto without departing from the scope of the present invention.
