Technical Field
[0001] This utility model belongs to the field of ice-making equipment, specifically relating to a sensing device for detecting whether an ice maker is full of ice. Background Technology
[0002] An ice maker is a refrigeration machine that uses a refrigeration system to cool water through an evaporator to produce ice. The shape of the ice blocks varies depending on the evaporator's principle and the production method. Flow-type ice makers use a spray method to spray water into ice trays, thus producing square ice. However, due to the shape and stacking of these square ice blocks, they tend to fill the ice basket completely.
[0003] Therefore, it is necessary to develop a sensing device that can detect whether the ice basket is full of ice. Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a sensing device for an ice maker that can detect whether the ice basket of the ice maker is full of ice.
[0005] To achieve the above objectives, the solution adopted by this utility model is as follows:
[0006] A sensing device for an ice maker includes a freezing assembly, a rocker, a first sensor, and a second sensor. The rocker is disposed below the freezing assembly and is rotatable about a pivot. The rocker has a first plate side and a second plate side on both sides of the pivot, and the torque of the second plate side is greater than that of the first plate side. The first sensor is disposed on the second plate side, and the second sensor is fixed below the rocker.
[0007] By adopting this technical solution, the first sensor moves up and down as the rocker rotates around its pivot, causing the second sensor to output two different sensing signals to determine whether the ice basket is full. Furthermore, the rocker for full ice detection is located below the freezing unit, effectively detecting whether the ice basket is full without false alarms or failing to detect when it is full.
[0008] According to the sensing device of the ice maker described above, the mass of the second plate side is greater than that of the first plate side, so as to achieve a greater torque on the second plate side and reduce the size of the device.
[0009] According to the above-mentioned sensing device of the ice maker, the freezing assembly is provided with connecting arms, two connecting arms are spaced apart to form a mounting cavity, and the rocker is pivotally disposed between the two connecting arms.
[0010] According to the above-mentioned sensing device of the ice maker, the connecting arm is provided with a shaft hole, and the two ends of the rocker are provided with corresponding shaft posts; this simplifies the structure and makes it easy to manufacture and install.
[0011] According to the above-mentioned sensing device for the ice maker, the connecting arm is integrally formed on the freezing component, and the pivot is located near the opening of the freezing chamber of the freezing component, so that the device can be formed into an integral structure. It can replace the existing freezing component of the ice maker to provide a full ice detection function, which is easy to manufacture ice makers.
[0012] According to the above-mentioned sensing device for the ice maker, the first sensing element is a magnet, and the second sensing element is a magnetic sensor, so as to be suitable for use in the ice maker and not to contaminate the water or ice.
[0013] According to the above-mentioned sensing device of the ice maker, the second plate has a fixing cavity on its side for mounting a magnet.
[0014] According to the sensing device of the ice maker described above, a protrusion is provided on the far end of the side of the first plate, and a contact point is provided on the lower surface of the protrusion so as to provide support when the first side plate rotates downward, thereby preventing the ice from colliding and breaking.
[0015] According to the above-mentioned sensing device of the ice maker, the heat exchange tube is located in the freezing chamber of the freezing component, and the ice tray is at least partially accommodated in the freezing chamber; the water supply pipe assembly is installed on the freezing component, and a spray pipe is formed above the freezing chamber, thereby realizing flow spray ice making.
[0016] According to the above-mentioned sensing device of the ice maker, the top of the freezing component is provided with a positioning recess for the spray pipe to be installed therein, so that the spray pipe is positioned and easy to install.
[0017] The sensing device of this invention is suitable for use in mobile ice makers and can effectively detect whether the ice basket is full. Once the basket is full, it can output a signal to the controller to stop ice making. Attached Figure Description

[0029] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model will be described in detail below with reference to certain specific embodiments.
[0030] like Figure 1-6 As shown, a sensing device is used in ice makers, particularly mobile freezing ice makers, to detect whether the ice basket is full. The ice basket is a common component of mobile ice makers, installed below the freezing assembly to collect the ice being made.
[0031] like Figure 1 As shown, the sensing device includes a freezing assembly 11, which is a component of a water-cooled ice maker used to make ice cubes by freezing water after spraying it. The freezing assembly 11 includes a main body with a freezing chamber 111 inside. A positioning recess 113 is provided above the main body. A heat exchange tube 114 is installed on the rear side wall of the freezing chamber 111. An ice tray 112 is installed inside the freezing chamber 111 and its rear end contacts the heat exchange tube 114 to be cooled.
[0032] The water supply pipe assembly 101 is fixed to the refrigeration unit 11. The water supply pipe assembly 101 includes a spray pipe 102 positioned horizontally above the refrigeration unit 11. The spray pipe 102 has a plurality of spray holes and is positioned and assembled in the positioning recess 113 of the refrigeration unit 11. The water supply pipe assembly 101 also has a water inlet end 103 for inputting a water source, such as being connected to a water pump for water supply.
[0033] In this embodiment, two connecting arms 115 are protruding at the lower end of the main body of the freezing assembly 11. The two connecting arms 115 are spaced apart to form an installation cavity 116 between them. The rocker 12 is installed in the installation cavity 116 and is rotatably mounted around the pivot 100, so that the rocker 12 is rotatably pivoted below the ice tray 112.
[0034] To pivotally mount the rocker arm 12, a shaft hole 117 is provided on the connecting arm 115, and corresponding shaft posts 121 are provided at both ends of the rocker arm 12. The rocker arm 12 is pivotally mounted by installing the shaft posts 121 in the shaft hole 117. In other embodiments, a pin can also be used for pivot connection, for example, by providing pivot holes on the rocker arm 12 and the connecting arm 115 respectively, and then using a pin to pass through.
[0035] The seesaw 12 has a first side plate 122 and a second side plate 123 on both sides of the pivot 100, with the first side plate 122 opening towards the ice tray 112, so that ice cubes sliding from the ice tray 112 can fall onto the first side plate 122; and the torque of the second side plate 123 is greater than that of the first side plate 122, so that under the action of gravity, the second side plate 123 is at a low point and the first side plate 122 is at a high point. When ice cubes accumulate on the first side plate 122, its overall weight increases, causing its torque to increase and become greater than that of the second side plate 123 (the torque of the second side plate 123 is constant), so that the seesaw 12 rotates around the pivot 100 in a seesaw-like manner, causing the second side plate 123 to be at a high point and the first side plate 122 to be at a low point.
[0036] Preferably, a protrusion 125 is provided on the far end of the first plate side 122 of the rocker 12, and a contact 126 is provided on the lower surface of the protrusion 125. The contact 126 is preferably hemispherical or cylindrical.
[0037] In this embodiment, a first sensor 13 is provided on the side portion 123 of the second plate, and a second sensor 14 is fixedly provided at a predetermined distance below the side portion 123 of the second plate. The second sensor 14 is preferably installed at an appropriate position inside the ice maker. The second sensor 14 outputs different sensing signals by sensing the change in distance between the first sensor 13 and the first sensor 13, which is used to determine the state of the rocker 12, that is, whether it is in the first state where the side portion 123 of the second plate is at a low point or in the second state where the side portion 122 of the first plate is at a low point. Based on the state change and whether it is maintained in the state, the second sensor outputs whether the ice maker is full of ice.
[0038] A fixing cavity 124 is provided on the far end of the second plate side 123 for the first sensing element 13 to be installed therein.
[0039] Preferably, the first sensing element 13 is a magnet, and the second sensing element 14 is a magnetic sensor. In other embodiments, the first and second sensing elements can also be implemented using distance sensors, contact sensors, or the like.
[0040] The working principle of the sensing device for the ice maker in this embodiment is as follows:
[0041] 1. In the initial state, the second plate side 123 is at a low position due to its greater torque, and the first plate side 122 is at a high position. At this time, the distance between the two sensors is small or they are in contact, and the second sensor 14 can output a first sensing signal that is not full of ice.
[0042] Second, when ice blocks slide down, since the length of the side part 122 of the first plate is not large and the extension distance is not much, and the ice blocks slide down at a certain angle, it will not affect the rocker 12 much, and the rocker 12 remains in this state.
[0043] Third, when a certain amount of ice has accumulated in the ice basket, the ice will accumulate on the side 122 of the first plate when it slides down, which will increase the torque of the side 122 of the first plate. As a result, the rocker 12 will rotate and the side 123 of the second plate will tilt upward, which will increase the distance between the first sensor 13 and the second sensor 14 or separate them. The second sensor 14 can output the first sensing signal of full ice.
