Obviously, the described embodiments are only part of the embodiments of this specification, not all of them.

The following implementation methods will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0026] It should be understood that although terms such as "first," "second," and "third" may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another.

[0027] See Figure 1-2 , is an ice-making machine temperature control device of this embodiment, which is installed on the ice-making machine, wherein the ice-making machine includes a frame 100, a water pipe 200, an ice-making tray 300 and a controller 400. The water pipe 200 is arranged on the top of the ice-making tray 300 and fixed to the frame 100. The ice-making tray 300 is fixedly arranged on a side surface of the frame 100. The controller 400 is fixed to the frame. The ice-making machine temperature control device includes:

[0028] The bracket 1 includes a fixed section 11 and a detection section 13 connected to each other, wherein the fixed section 11 of the bracket 1 is connected to the water pipe 200, and the bracket 1 is arranged to avoid the ice making tray 300;

[0029] The hollow tube 2 is fixed on the side of the detection section 13 of the bracket 1 facing the ice making tray 300, and there is a preset distance between the hollow tube 2 and the ice making tray 300;

[0030] The temperature sensor 3 has a first end and a second end that are arranged opposite to each other. The first end of the temperature sensor 3 is inserted into the hollow tube 2, and the second end of the temperature sensor 3 is inserted from the detection section 13 of the bracket 1 away from the ice making tray 300 and is connected to the controller 400 for signal connection.

[0031] For the above structure, during installation, first select a bracket 1 with a preset size. The fixed section 11 and the detection section 13 of the bracket 1 are connected end to end, and the bracket 1 is an integrated structure. Therefore, the connection angle between the fixed section 11 and the detection section 13 of the bracket 1 needs to be specially pre-set to avoid that after the fixed section 11 of the bracket 1 is installed on the water pipe 200 at the top of the ice cube tray 300, other positions of the bracket 1 itself will touch the ice cube tray 300, and the hollow tube 2 installed on the detection section 13 of the bracket 1 can be closer to the ice cube tray 300, so that the temperature sensor 3 in the ice cube tray 300 can more sensitively sense the temperature of the homemade ice cube tray 300.

[0032] With the above structure, when in use, the operator only needs to start the ice maker and connect the temperature sensor 3 to the external controller 400. The water tank 600 pumps water into the water pipe 200 at the top of the ice making grid 300 through the water pump, and the water flows from the water pipe 200 to the ice making grid 300, so that each small grid in the ice making grid 300 is gradually filled with an equal amount of flowing water. At the same time, the evaporator 500 is also started and continuously keeps cooling the ice making grid 300, so that the flowing water in the ice making grid 300 turns into an ice layer. After a certain period of time, the ice layer in the ice making grid 300 becomes thicker and thicker, and gradually The temperature sensor 3 is close to the hollow tube 2, and the temperature sensor 3 therefore senses the decrease in air heat until the ice layer in the ice making tray 300 becomes thick enough, and even the flowing water on one side of the ice layer touches the hollow tube 2 of the temperature sensor 3. At this time, the temperature sensor 3 receives the preset temperature and sends it to the controller 400. The controller 400 determines that the thickness of the ice layer has met the requirements of the finished ice cubes leaving the factory, and then starts the subsequent operations of stopping the evaporator 500 from cooling, stopping the water supply from the water tank 600, and starting heating to make the ice cubes in the ice making tray 300 fall off, thereby completing the final ice collection.

[0033] During the above-mentioned use, the thickness of the ice layer is judged by the temperature sensor 3, which replaces the more complex structures such as the traditional float, and has lower costs. In addition, with the help of the multi-segment bracket 1, the fixed section 11 and the detection section 13 of the bracket 1 are connected end to end, the angle is flexible and changeable, it is easy to install and maintain, and has a wider range of uses.

[0034] Furthermore, if Figure 2As shown, the fixed section 11 of the bracket 1 includes rotating shafts 111 on both sides. The water pipe 200 includes protruding sleeves. The rotating shafts 111 match the sleeves in size and are inserted into the sleeves, allowing the bracket 1 to rotatably connect to the water pipe 200. When the bracket 1 rotates in the forward direction, the temperature sensor 3 in the hollow tube 2 approaches the ice cube tray 300. When the bracket 1 rotates in the reverse direction, the temperature sensor 3 in the hollow tube 2 moves away from the ice cube tray 300. Specifically, in this embodiment, the ice maker temperature control device also includes an adjustment mechanism 4. A connecting section 12 is provided between the fixed section 11 and the detection section 13. The connecting section 12 of the bracket 1 has a through hole. The adjustment mechanism 4 is inserted into the through hole, and one end of the adjustment mechanism 4 abuts the frame 100 on one side of the ice cube tray 300. Specifically, the outer periphery of the adjustment mechanism 4 has external threads, and the inner periphery of the through hole has internal threads. The external and internal threads match, allowing the adjustment mechanism 4 to be threadedly connected to the connecting section 12. With the help of this embodiment, when it is necessary to adjust the gap between the temperature sensor 3 and the ice cube tray 300, it is only necessary to rotate the adjustment mechanism 4. When rotating clockwise, the adjustment mechanism 4 extends to the side of the connecting section 12 facing the bracket 1, and the temperature sensor 3 moves away from the ice cube tray 300. When rotating counterclockwise, the adjustment mechanism 4 retracts from the side of the connecting section 12 facing the bracket 1, and the temperature sensor 3 moves closer to the ice cube tray 300. The control accuracy of the distance between the temperature sensor 3 and the ice cube tray 300 is relatively high.

[0035] Furthermore, the hollow tube 2 is configured as a U-shaped tube, with both ends of the hollow tube 2 respectively positioned at the edges of the detection section 13 of the bracket 1. Meanwhile, the first end of the temperature sensor 3 is positioned in the middle of the hollow tube 2. Specifically, the hollow tube 2 in this embodiment is constructed of stainless steel, which has excellent thermal conductivity and is effectively protected from rusting during use. Furthermore, the conductor portion of the temperature sensor 3, which senses heat changes, is positioned in the middle of the stainless steel U-shaped tube, enabling the hollow tube 2 to quickly and evenly transfer heat changes from the ice cube tray 300 to the temperature sensor 3.

[0036] Furthermore, the temperature sensor is set as an NTC thermistor sensor, which has the characteristics that its resistance value decreases as the temperature increases, and it is more sensitive to reaction. It is suitable for use in a small range of temperature changes in the ice maker environment, has low cost and long service life.
