Description

Technical Field

[0001] The present invention relates to the technical field of ice skate sharpening constant temperature equipment, and particularly to an automatic constant temperature freezer. Background Art

[0002] In the business premises of curling training, an ice skate sharpener is a tool for repairing the ice surface of an ice rink. When skaters slide on the ice surface, it will cause wear and scratches on the ice surface. When multiple people train, potholes will appear on the ice surface, affecting the smoothness and safety of sliding. Therefore, using an ice skate sharpener to repair the ice surface can keep it flat and smooth.

[0003] Currently, the existing ice skate sharpeners are made of metal. At room temperature, their temperature is higher than that of the ice surface. During the process of repairing the ice surface, when the ice skate sharpener contacts the ice surface, it is easy to cause melting or sticking of the ice surface, resulting in damage to the ice surface and thus inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic constant temperature freezer to solve the problems raised in the above background art.

[0006] As a further preferred embodiment of this technical solution, it further comprises: a protective frame provided on one side of the adjustment box, and the constant temperature tank is located inside the protective frame; three protective plates are all slidably connected in the grooves of the protective frame; the protective plates and the protective frame are arranged to cooperate to limit the contact between the ice in the constant temperature box and the external air.

[0012] The present invention provides an automatic constant temperature freezer, which has the following beneficial effects:

[0013] (1) In the present invention, by adding water into the constant temperature box, turning on the compressor, and through the cooperation of the condenser and the evaporator, the water in the constant temperature box is made into ice. Then, when the ice resurfacer is placed on the ice surface, the infrared thermometer monitors the temperature of the ice. When the temperature is high, the power of the compressor is increased. When the temperature of the ice is low, the heater is turned on to heat the ice, ensuring that the temperature of the ice in the constant temperature box is the same as the temperature of the ice rink for curling training. This structural design ensures that the temperature of the ice resurfacer during use is the same as the temperature of the ice rink, preventing the ice surface from melting or sticking to the blade when repairing the ice surface.

[0014] (2) Through the structural design of the protective frame and the protective plate in the present invention, when the ice resurfacer is placed on the ice surface in the constant temperature box, the nut is rotated, and the thread on the surface of the fixed screw moves along the thread groove, so that one end of the fixed screw releases the restriction on the protective plate. The protective plate slides in the groove in the protective frame, closing the protective frame and isolating the ice from the air, reducing ice melting. This structural design can reduce the running time and frequency of the ice-making equipment, and reduce the consumption of resources such as electricity and water. Description of the Drawings

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] Embodiment 1: As Figure 1 - Figure 5 shown, in this embodiment, an automatic constant temperature freezer includes: an adjustment box 1; a constant temperature tank 2 provided on one side of the adjustment box 1; a constant temperature box 8 installed in the constant temperature tank 2; a compressor 12 provided in the adjustment box 1; a condenser 13 provided in the adjustment box 1; an evaporator 10 installed in the constant temperature tank 2 and located between the constant temperature tank 2 and the constant temperature box 8; a heater 11 installed in the constant temperature tank 2 and located between the constant temperature tank 2 and the constant temperature box 8; the evaporator 10 and the heater 11 are arranged to cooperate with the ice in the constant temperature box 8 to maintain a constant temperature state, so that the ice resurfacer on the ice surface has the same temperature as the ice rink.

[0023] By adding water into the constant temperature box 8, turning on the compressor 12, and the cooperation of the condenser 13 and the evaporator 10, the water in the constant temperature box 8 is made into ice. When the ice resurfacer is placed on the ice surface, the infrared thermometer 9 monitors the temperature of the ice. When the temperature is high, the power of the compressor 12 is increased. When the temperature of the ice is low, the heater 11 is turned on to heat the ice, ensuring that the temperature of the ice in the constant temperature box 8 is the same as the temperature of the ice rink for curling training. This structural design ensures that the temperature of the ice resurfacer during use is the same as the temperature of the ice rink, preventing the ice resurfacer from causing melting or sticking on the ice surface during ice surface repair; wherein the compressor 12 compresses the refrigerant into a high-temperature and high-pressure gas. Through the operation of the compressor 12, the pressure and temperature of the refrigerant are increased. The high-temperature and high-pressure refrigerant gas enters the condenser 13. In the condenser 13, the refrigerant exchanges heat with the external environment, transferring the heat to the surrounding air or cooling water, so that the refrigerant gas is cooled and condensed into a high-temperature and high-pressure liquid. The high-temperature and high-pressure refrigerant liquid cooled by the condenser 13 enters the evaporator 10 after throttling and pressure reduction through the expansion valve. In the evaporator 10, the pressure of the refrigerant decreases, and the liquid begins to evaporate and gasify, absorbing the heat in the constant temperature box 8, reducing the temperature of the constant temperature box 8, and making the water in the constant temperature box 8 into ice.

[0024] Embodiment 2: As Figures 1-3As shown, it further includes: a protective frame 3, arranged on one side of the adjustment box 1, and the constant temperature tank 2 is located inside the protective frame 3; three protective plates 6, all slidably connected in the grooves of the protective frame 3; the protective plates 6 and the protective frame 3 are arranged to cooperate to limit the contact between the ice in the constant temperature box 8 and the external air.

[0025] Through the structural design of the protective plate 6 and the protective frame 3, the ice in the constant temperature box 8 is isolated from the air, reducing the melting of the ice. This structural design can reduce the operating time and frequency of the ice-making equipment, and reduce the consumption of resources such as electricity and water.

[0026] As Figure 1 - Figure 4 As shown, it further includes: a plurality of nuts 7, all arranged on the protective frame 3; a plurality of fixing screws 14, respectively fixedly connected to one side of the plurality of nuts 7; a plurality of threaded grooves 15, all opened on the protective frame 3, and the outer surface of the fixing screw 14 is threadedly connected to the inner wall of the threaded groove 15; the fixing screw 14 and the threaded groove 15 are arranged to cooperate to limit the position of the protective plate 6 in the protective frame 3.

[0027] Through the structural design of the fixing screw 14 and the threaded groove 15, the protective plate 6 is restricted in the groove in the protective frame 3, and the height of the protective plate 6 in the protective frame 3 can be fixed, avoiding the need to disassemble the ice trimming knife when installing the ice trimming knife on the equipment and then placing it on the ice surface.

[0028] As Figure 1 As shown, it further includes: a disassembly plate 4, installed on the adjustment box 1 by bolts.

[0029] Through the structural design of the disassembly plate 4, the disassembly plate 4 can be disassembled from the adjustment box 1, facilitating the maintenance of the equipment inside the adjustment box 1.

[0030] As Figure 1 As shown, it further includes: a plurality of heat dissipation holes 5, all penetratingly opened on the disassembly plate 4.

[0031] Through the structural design of the heat dissipation holes 5, the equipment inside the adjustment box 1 can be cooled and dissipated heat, improving the service life of the equipment.

[0032] As Figure 3 and Figure 5 As shown, it further includes: an infrared thermometer 9, installed at the inner top of the protective frame 3.

[0033] Through the structural design of the infrared thermometer 9, the temperature of the ice in the constant temperature box 8 can be monitored in real time, ensuring that the temperature of the ice in the constant temperature box 8 is the same as the temperature of the ice rink.

[0034] As Figure 3 and Figure 5As shown, the output end of the compressor 12 is fixedly communicated with the input end of the condenser 13, the output end of the condenser 13 is fixedly communicated with the input end of the evaporator 10, and the output end of the evaporator 10 is fixedly communicated with the input end of the compressor 12.

[0035] The present invention provides an automatic constant-temperature freezer, and the specific working principle is as follows:

[0036] After the ice resurfacer finishes repairing the ice surface of the curling training ice rink, add water into the constant-temperature box 8, turn on the compressor 12, and through the cooperation of the condenser 13 and the evaporator 10, make the water in the constant-temperature box 8 into ice. Then place the ice resurfacer on the ice surface of the constant-temperature box 8, and the infrared thermometer 9 monitors the temperature of the ice. When the temperature is too high, increase the power of the compressor 12; when the temperature of the ice is too low, turn on the heater 11 to heat the ice, so as to ensure that the temperature of the ice in the constant-temperature box 8 is the same as the temperature of the curling training ice rink, and ensure that the temperature of the ice resurfacer is the same as the ice surface of the ice rink.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
