Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an ice cream freezer capable of preventing freezing and draining water. Background Art
[0002] The refrigeration principle of the ice cream freezer is to use cold air to blow out and let the cold air evenly cover every corner of the cabinet to achieve the effect of freezing the product. Since the freezer is in a freezing state for a long time, the moisture in the freezer evaporates and then condenses into frost, and the frost accumulates thicker and thicker, affecting the refrigeration effect of the freezer. In this case, the freezer needs to be defrosted and cleaned and discharged through the drain pipe.
[0003] However, the existing ice cream freezer is in a frozen state for a long time, and water is easily retained in the drain pipe of the freezer, which causes the residual water in the drain pipe to freeze and block the drain pipe. When the freezer is defrosted or cleaned, the drainage structure cannot drain water normally, causing water to accumulate in the freezer, affecting the cleaning and defrosting of the freezer. Therefore, an ice cream freezer with antifreeze and drainage is proposed to solve the above problem. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides an ice cream freezer capable of preventing freezing and draining water, which has the advantage of preventing freezing of the drain pipe.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ice cream freezer with antifreeze and drainage, comprising a cabinet body, a drain pipe connected to the outside extending from the bottom of the cabinet body, a sealing cover movably provided on the water inlet of the drain pipe, and characterized in that: it also includes a PLC controller, a cross baffle is rotatably connected to the water outlet of the drain pipe, and the cross baffle is connected to a sensor, the sealing cover is electrically connected to the sensor, so that when the sealing cover is opened or closed, the sensor is powered on or off, a cavity is opened in the wall of the drain pipe, and a heating wire surrounding the drain pipe is provided in the cavity, the heating wire and the sensor are electrically connected to the PLC controller respectively, so that when the cross baffle does not rotate, the heating wire is controlled by the PLC controller to be powered on and heated.
[0006] Furthermore, a guide plate extends obliquely in the drainage pipe, and the guide plate covers half of the cross baffle.
[0007] Furthermore, the cross baffle is configured as a circular structure so that the cross baffle completely covers the drain pipe.
[0008] Furthermore, a counterweight is fixed on one of the cross baffles.
[0009] Furthermore, a pull ring is fixed on a side of the sealing cover away from the drain pipe.
[0010] Furthermore, a time relay is connected to the cross baffle, and the time relay is electrically connected to the PLC controller.
[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0012] The ice cream freezer with antifreeze and drainage is provided with a cross baffle in the drain pipe, so that when the sealing cover is opened to drain water, the sensor of the cross baffle is energized. If the water in the freezer cannot be normally drained due to water accumulation in the drain pipe and ice forming in the freezer, the cross baffle cannot rotate. The sensor senses and controls the heating wire to energize and heat the drain pipe through a PLC controller, so that the ice in the drain pipe thaws and the water can be drained normally. It is convenient and quick. When the water flow hits the cross baffle, the cross baffle rotates, and the sensor senses and controls the heating wire to cut off the power and stop heating through the PLC controller, so as to prevent continuous heating and waste of electricity.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] See also Figure 1-4 An ice cream freezer with antifreeze and drainage in the present application comprises a cabinet body 1, a drain pipe 2 connected to the outside extending from the bottom of the cabinet body 1, a sealing cover 3 movably provided on the water inlet of the drain pipe 2, and a PLC controller. A cross baffle 4 is rotatably connected to the water outlet of the drain pipe 2, and the cross baffle 4 is connected to a sensor. The sealing cover 3 is electrically connected to the sensor, so that when the sealing cover 3 is opened or closed, the sensor is powered on or off. A cavity 5 is opened in the wall of the drain pipe 2, and a heating wire 6 surrounding the drain pipe 2 is provided in the cavity 5. The heating wire 6 and the sensor are electrically connected to the PLC controller respectively, so that when the cross baffle 4 does not rotate, the heating wire 6 is controlled by the PLC controller to be powered on and heated.
[0020] When the cabinet 1 is defrosted or cleaned, the sealing cover 3 is opened and the PLC controller is connected to the power supply. If the drain pipe 2 is blocked by ice, the cross baffle 4 cannot rotate. At this time, the sensor on the cross baffle 4 controls the heating wire 6 through the PLC controller to heat the drain pipe 2, thaw the ice in the drain pipe 2, and allow the drain pipe 2 to drain normally, which is convenient and quick. When the drain pipe 2 drains normally, the water flow hits the cross baffle 4, causing the cross baffle 4 to rotate. At this time, the sensor on the cross baffle 4 controls the heating wire 6 through the PLC controller to cut off the power and stop heating. When the drainage is completed, the sealing cover 3 is covered. At this time, the PLC controller is powered off, so that when the cross baffle 4 does not rotate, the heating wire 6 cannot be automatically heated, thereby preventing the heating wire 6 from continuously heating and wasting electricity.
[0021] A guide plate 7 extends obliquely in the drain pipe 2, and covers half of the cross baffle 4. The guide plate 7 guides the water flow to one side of the cross baffle 4, so that the cross baffle 4 can continue to rotate in one direction to prevent it from swaying left and right and unable to rotate.
[0022] The cross baffle 4 is set to a circular structure so that the cross baffle 4 completely covers the drain pipe 2. The circular cross baffle 4 increases the contact area with the water flow, making its force-bearing area larger and easier to rotate.
[0023] A counterweight 8 is fixed on one of the baffles of the cross baffle 4. When the drain pipe 2 does not drain water, the counterweight 8 makes one of the baffles of the cross baffle 4 face vertically downward, and the baffles on both sides will block the water outlet of the drain pipe 2 to prevent impurities from entering the drain pipe 2 and causing blockage.
[0024] A pull ring 9 is fixed to the side of the sealing cover 3 away from the drain pipe 2 , and the pull ring 9 makes it more convenient to pull out the sealing cover 3 .
[0025] A time relay is connected to the cross baffle 4, and the time relay is electrically connected to the PLC controller. Since it takes a certain amount of time for water to flow onto the cross baffle 4, when the corresponding time is exceeded and the cross baffle 4 has not rotated, the sensor controls the heating of the heating wire 6 through the PLC controller. If the corresponding time is not exceeded, the sensor cannot control the heating of the heating wire 6 through the PLC controller, to prevent the heating wire 6 from being heated when the drain pipe 2 is not blocked and the water has not yet flowed to the cross baffle 4, thereby wasting electricity.
[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
