Description

[0002] Snow melting equipment is a machine used to make various fruit juices into refreshing snow-melt beverages. It mainly includes a material tank, an evaporator and an agitator. The evaporator is placed in the material tank as part of the refrigeration system of the snow melting equipment. When working, it is used to cool the material in the tank. The agitator stirs and mixes the material, and discharges the material through the agitator or the discharging system when discharging is required.

[0003] In the related art, the refrigeration device of snow-melting equipment is mainly a coiled-tube evaporator, which uses a spiral copper tube wound inside a refrigeration cylinder. During operation, the low-temperature, low-pressure refrigerant exchanges heat with the refrigeration cylinder through the spiral copper tube, and then exchanges heat with the material inside the cylinder through the refrigeration cylinder to cool the material. Because water has a very low freezing point, when the beverage in the cylinder has a high water content, the water will condense on the surface of the refrigeration cylinder and freeze. Moreover, as the thickness of the ice continues to increase, the internal space of the cylinder continues to shrink, and the agitator in the cylinder will become stuck and unable to operate normally, seriously affecting the normal production of smoothies and providing a poor user experience.

[0024] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] See also Figure 1 and Figure 2 , an embodiment of the present application provides a method for controlling a snow melting device, comprising the following steps:

[0026] Step S1: when the snow melting device is in the smoothie making mode, obtaining a first rotation speed of the blender 100;

[0027] Step S2: If the first speed is less than the preset speed, the compressor 200 is controlled to stop working, and at the same time, the stirrer 100 is controlled to continue running for the first time period;

[0028] Step S3, obtaining a second rotation speed of the stirrer 100 after the first time period;

[0029] Step S4: If the second rotational speed is less than the preset rotational speed, the stirrer 100 is controlled to stop working, and at the same time, the refrigerant reversing valve of the compressor 200 is controlled to reverse once to enter the ice melting mode.

[0030] In the present embodiment, an ice-melting program is added to the smoothie-making mode for identifying the situation where the thickness of ice on the surface of the compressor 200 is too thick and affects the normal stirring of the blender 100. The ice-melting program determines whether the thickness of ice on the surface of the compressor 200 is too thick by obtaining the stirring speed of the blender 100. When the thickness of ice on the surface of the compressor 200 is too thick, the compressor 200 is stopped from continuing to refrigerate, and the refrigerant reversing valve of the compressor 200 is controlled to reverse once, so that it is in a heating state to melt the ice layer condensed on its surface, thereby eliminating the influence of the ice layer on the blender 100, improving the stirring effect, improving the smoothie making effect, and improving the user experience.

[0031] The control procedure of the snow melting device in this embodiment is as follows: first, the power button on the snow melting device is activated to put the snow melting device into operation. Then, the smoothie making mode of the snow melting device is selected to put the snow melting device into the smoothie making mode so that a room temperature liquid beverage can be made into a beverage smoothie. At this time, the compressor 200 and the blender 100 are both in the on state. The compressor 200 can cool the beverage in the material tank and condense the low-temperature beverage into a smoothie state under the stirring action of the blender 100. It can be understood that the snow melting device also has a standby mode and an ice water mode. In the standby mode, the snow melting device is turned on and is in a low power state, which can quickly respond to the smoothie making mode and the ice water mode. In the ice water mode, the snow melting device can cool the room temperature beverage to a cold liquid state above 0 degrees Celsius and below 10 degrees Celsius, providing the user with an ice-cold drink. Then, the first speed of the blender 100 in the smoothie making mode is obtained, and the first speed is compared with the preset speed. If the first speed is less than the preset speed, it means that the blender 100 rotates too slowly and its stirring action is hindered. It can be considered that the thickness of the ice layer condensed on the surface of the compressor 200 is too thick and occupies the working space of the blender 100. At this time, it is determined that there is an abnormality in the smoothie making mode, and the compressor 200 needs to be turned off to prevent it from continuing to make ice and causing a larger ice layer to condense on its surface. At the same time, the blender 100 is driven to rotate for a first time length, such as 1 minute, and the second speed after the first time length is obtained. The second speed is compared with the preset speed. If the second speed is lower than the preset speed, it is determined that the abnormally slow speed of the blender 100 is caused by the ice layer on the surface of the compressor 200. At this time, the blender 100 needs to be turned off to prevent the blender 100 from continuing to rotate and damaging its stirring blades. At the same time, the refrigerant reversing valve of the compressor 200 and the compressor 200 are turned on to put the compressor 200 in a heating state, so that the ice layer condensed on its surface can be melted, eliminating the influence of the ice layer on the surface of the compressor 200 on the blender 100, solving the freezing problem of the snow melting equipment, improving the ice smoothie making effect, and increasing the service life of the snow melting equipment.

[0032] For example, but not limited to, the preset speed of the blender 100 in the smoothie making mode is 1600 rpm to 4000 rpm. If the speed of the blender 100 is detected to be within this range, it is determined that the blender 100 is operating normally and the smoothie making mode of the snow melting device is normal.

[0033] In a possible implementation, controlling the refrigerant reversing valve of the compressor 200 to reverse once and enter the ice melting mode further includes:

[0034] Step S41: After the refrigerant reversing valve of the compressor 200 is reversed once for a second time period, obtaining surface icing information of the compressor 200;

[0035] Step S42: If the surface icing information is within the normal icing range, the agitator 100 is controlled to restart.

[0036] In this embodiment, after the snow melting device's ice melting process, a procedure is added to determine whether the ice on the surface of compressor 200 has melted to a degree that does not affect the normal operation of blender 100. Specifically, after compressor 200 enters heating mode and operates for a second period of time, such as 5 minutes of heating, ice information on the surface of compressor 200, such as ice thickness and area, can be acquired using an image capture device, such as an industrial camera. This ice information is then compared with the normal ice range. If the acquired ice information is within the normal ice range, such as an ice thickness of 0 cm or 0.5 cm, which is less than the normal ice thickness range of 1 cm to 2 cm, the ice on the surface of compressor 200 has melted, indicating that there is no surface ice or that the surface ice is in a normal state. At this point, the blender 100 can be driven by the motor to resume blending, and the entire snow melting device enters the transition phase between ice melting and smoothie making. This procedure is primarily designed to address abnormal ice formation on the surface of compressor 200, ensuring that the snow melting device can resume normal operation after the abnormality is resolved.

[0037] In one possible implementation, controlling the stirrer 100 to restart operation includes:

[0038] Step S43: starting the stirrer 100 and obtaining a third rotational speed of the stirrer 100;

[0039] Step S44: If the third speed is greater than or equal to the preset speed, the refrigerant reversing valve of the compressor 200 is controlled to perform a second reversal to enter the ice-making mode.

[0040] In this embodiment, during the restart operation of the blender 100, a judgment procedure for the rotation speed of the blender 100 and the preset rotation speed is added to ensure that the ice layer on the surface of the compressor 200 does not affect the normal blending operation of the blender 100. Specifically, after the blender 100 is restarted, the third rotation speed of the blender 100 can be obtained through components such as a rotation speed sensor, and the third rotation speed is compared with the preset rotation speed. If the third rotation speed is greater than or equal to the preset rotation speed, it is determined that the rotation speed of the blender 100 is normal and the smoothie making mode returns to normal. At this time, the refrigerant reversing valve of the compressor 200 needs to be opened again to put the compressor 200 in a refrigeration state, so that a cold source can continue to be provided to the beverage in the material cylinder, the smoothie making operation can continue, and the user experience is improved.

[0041] In a possible implementation, controlling the refrigerant reversing valve of the compressor 200 to perform a secondary reversal to enter the ice-making mode further includes:

[0042] Step S45: After the refrigerant reversing valve of the compressor 200 performs a second reversing operation for a third time period, a fourth rotational speed of the agitator 100 is obtained.

[0043] Step S46: If the fourth speed reaches the target speed, obtain the first material temperature in the material cylinder of the snow melting equipment.

[0044] Step S47: If the first material temperature reaches the target material temperature, the compressor 200 is controlled to stop working.

[0045] Step S48: If the first material temperature does not reach the target temperature, control the compressor 200 to continue working.

[0046] In this embodiment, after the compressor 200 re-enters the ice-making mode, considering that the ice layer on the surface of the compressor 200 has melted and ice accumulation will not occur in the short term, a target speed and target temperature detection / judgment program is set to determine whether the compressor 200 can be controlled to stop operation and continue to blend the smoothie using residual cooling to save energy. Specifically, after the second reversal and after the blender 100 has run for a third period of time, such as 5 minutes, a fourth speed of the blender 100 can be obtained by the speed sensor and compared with the target speed. If the fourth speed reaches the target speed, such as 2500 rpm, the speed of the blender 100 is determined to be appropriate. If the fourth speed reaches the target speed, the liquid temperature in the material cylinder can be obtained through the temperature sensor, and the obtained first material temperature can be compared with the target material temperature. If the first material temperature reaches the target material temperature, such as 0 degrees Celsius, it means that the heat exchange of the beverage in the material cylinder is completed. At this time, the compressor 200 can be turned off and the refrigeration can be stopped to save the cold source. The beverage cooled to the target material temperature can be transformed from liquid to solid smoothie under the stirring of the blender 100 at the target speed.

[0047] In a possible implementation, when the snow melting device is in the smoothie making mode, obtaining the first rotational speed of the blender 100 further includes:

[0048] Step S11: If the first speed is greater than or equal to the preset speed, the compressor 200 is controlled to continue to operate, and at the same time, the stirrer 100 is controlled to operate for a fourth time period, and a fifth speed of the stirrer 100 after the fourth time period is obtained;

[0049] Step S12: If the fifth speed is greater than or equal to the target speed, obtaining a second material temperature in the material cylinder of the snow melting equipment;

[0050] Step S13: If the second material temperature reaches the target material temperature, the compressor 200 is controlled to stop working.

[0051] In this embodiment, in the smoothie making mode, if the first speed of the blender 100 is greater than or equal to the preset speed, it indicates that the blender 100 is rotating normally and blending is smooth and unimpeded. At this point, the smoothie making mode is determined to be normal, and the compressor 200 is activated to continue cooling. The blender 100 is then controlled to continue blending for a fourth duration, such as 2 minutes. After the fourth duration, the fifth speed of the blender 100 is acquired via the speed sensor and compared with the target speed. If the fifth speed reaches the target speed, such as 2500 rpm, the speed of the blender 100 is determined to be appropriate. If the fifth speed reaches the target speed, the temperature of the liquid in the mixing tank is acquired via the temperature sensor, and the acquired second temperature is compared with the target temperature. If the second temperature reaches the target temperature, such as 0 degrees Celsius, heat exchange of the beverage in the mixing tank is complete. The compressor 200 can then be deactivated, ceasing cooling to conserve cooling resources. The beverage, cooled to the target temperature, can then be transformed from a liquid into a solid smoothie under blending by the blender 100 at the target speed.

[0052] In a possible implementation, obtaining the second rotational speed of the stirrer 100 after the first time period further includes:

[0053] Step S31: If the second speed is greater than or equal to the preset speed, the compressor 200 is controlled to continue to operate, and at the same time, the stirrer 100 is controlled to operate for a fifth time period, and a sixth speed of the stirrer 100 after the fifth time period is obtained;

[0054] Step S32: If the sixth speed is greater than or equal to the target speed, obtain a third material temperature in the material cylinder of the snow melting equipment;

[0055] Step S33: If the third material temperature reaches the target material temperature, the compressor 200 is controlled to stop working.

[0056] In this embodiment, in the ice melting mode, if the second speed of the blender 100 after a second duration, such as 3 minutes, is greater than or equal to the preset speed, it indicates that the blender 100 is rotating normally and blending is smooth and unimpeded. At this point, the smoothie making mode is determined to be normal, and the compressor 200 is activated to continue cooling. The blender 100 is then controlled to continue blending for a fifth duration, such as 2 minutes. After the fifth duration, the speed sensor is used to obtain a sixth speed of the blender 100, and this sixth speed is compared with the target speed. If the sixth speed reaches the target speed, such as 2500 rpm, the speed of the blender 100 is determined to be appropriate. If the sixth speed reaches the target speed, the temperature of the liquid in the mixing tank is obtained by the temperature sensor, and the obtained third temperature is compared with the target temperature. If the third temperature reaches the target temperature, such as 0 degrees Celsius, heat exchange of the beverage in the mixing tank is complete. The compressor 200 can then be turned off, ceasing cooling to conserve cooling resources. The beverage, cooled to the target temperature, can be transformed from a liquid into a solid smoothie under blending by the blender 100 at the target speed.

The agitator 100, the compressor 200, the temperature sensor and the speed sensor are all arranged in the material tank, and the compressor 200 is separated from the agitator 100.

Furthermore, a refrigerant reversing valve is provided on the piping or fluid channel structure, which can be used to change the direction of the refrigerant, thereby achieving a cooling or heating effect. After the compressor 200 cools or heats the interior, it transfers the cold or heat source to its surface, which then contacts and exchanges heat with the beverage in the container, cooling the beverage and melting the ice on the compressor 200 surface.
