[0025] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 6 As shown, a specific embodiment of the present invention provides a water receiving mechanism for a cold drink machine, including a supporting seat 1 and a water receiving tray 2. The supporting seat 1 is mounted on a box body 3 of the cold drink machine. A motor seat 4 is provided at one end of the supporting seat 1. An ice making bin 5 is horizontally provided at one end of the motor seat 4. One end of the ice making bin 5 is mounted on the motor seat 4. A slide rail groove 11 and a water receiving tray 2 are provided in the other end of the supporting seat 1. A through opening 12 is provided at one end of the slide rail groove 11. The water receiving tray 2 slides into the slide rail groove 11 through the through opening 12. The water receiving groove 21 in the water receiving tray 2 is located directly below the ice making bin 5 to collect materials dropped from the ice making bin 5 above.

[0027] The orthographic projection of the connection between the ice making bin 5 and the motor base 4 is located in the water receiving groove 21, so as to ensure that during the process of removing the ice making bin 5 from the motor base 4, the materials dropped from the ice making bin 5 will stably fall into the water receiving groove 21, avoiding contamination of other positions of the box body 3. An external water receiving channel 6 is formed between the ice making bin 5 and the supporting seat 1, and the external water receiving channel 6 is respectively located on both sides of the supporting seat 1, and the external water receiving channel 6 is connected to the water receiving groove 21 to collect condensed water on the outer walls of both sides of the ice making bin 5.

[0028] At least one liquid level detection device 7 is provided on the upper part of the water receiving trough 21, and the liquid level detection device 7 is electrically connected to the controller of the cold drink machine, and the controller is also electrically connected to the sound and light alarm device on the cold drink machine. Among them, the water receiving trough 21 is provided with a first liquid level detection device 7 and a second liquid level detection device 7 at intervals along the height direction to detect the liquid level conditions at different heights. The first liquid level detection device 7 and the second liquid level detection device 7 are respectively arranged on both sides of the water receiving trough 21 to ensure the accuracy of liquid level detection through multiple liquid level signals at the same height, avoid false detection, and affect the stability of liquid level detection control. Secondly, the first liquid level detection device 7 is used to detect the warning liquid level of the water receiving trough 21, and the second liquid level detection device 7 is used to detect the alarm liquid level of the water receiving trough 21. Preferably, the liquid level detection device 7 is a liquid level detection sensor, but it is not limited to this.

[0029] It should be noted that the alarm level is the top position of the water tank 21. When the second level detection device 7 at this position triggers the level signal, it means that the material in the water tank 21 is about to overflow, and the user needs to clean it up as soon as possible. The position of the early warning level is below the position of the alarm level, and the distance between the two can be set according to actual needs; when the first level detection device 7 at this position triggers the level signal, it means that the material in the water tank 21 has reached the early warning level, which serves as an early warning to the user, and the user can clean it up or clean it up slowly when he has time later.

[0030] The beneficial effects of implementing the embodiments of the present invention are as follows:

[0031] The present invention is provided with a water receiving tray 2 below the ice making bin 5, the orthographic projection of the connection between the ice making bin 5 and the motor seat 4 is located in the water receiving groove 21, and an external water receiving channel 6 is formed between the ice making bin 5 and the supporting seat 1, and the external water receiving channels 6 are respectively located on both sides of the supporting seat 1, and the external water receiving channels 6 are connected to the water receiving groove 21. When the ice making bin 5 needs to be disassembled after operation, the ice or liquid flowing out of the ice making bin 5 will first flow from the connection between the ice making bin 5 and the supporting seat 1 to the water receiving tray 2 below, and in the subsequent process of the ice making machine being pulled out, the material flowing out of the ice making bin 5 will stably fall into the water receiving groove 21 below, so as to ensure that all the materials flowing out during disassembly fall into the water receiving groove 21, thereby realizing the function of collecting ice or liquid.

[0032] When the ice making bin 5 is in working state, condensed water is formed on the outer wall of the ice making bin 5 due to the low internal temperature. The condensed water at the upper part will flow to the bottom of the ice making bin 5 through the external water receiving channel 6, and the condensed water at the bottom of the ice making bin 5 will fall into the water receiving tray 2 below to further realize the liquid collection function. The above method can effectively prevent the outflowing materials from contaminating other positions of the box body 3, reduce the cleaning process, and improve the user's comfort and the safety of the use of electronic control components and circuits. In addition, when the collection capacity of the water receiving tray 2 is too much, the water receiving tray 2 can be removed from the slide rail groove 11 for discharge work, and the water receiving tray 2 can be reinstalled into the slide rail groove 11 for continued use. The overall disassembly and installation are convenient, and the practicability is high, which can improve the user's use experience.

[0033] In addition, the present invention provides a liquid level detection device 7 in the water receiving groove 21 of the water receiving tray 2 to detect different liquid level signals, so as to determine the liquid level in the water receiving groove 21 during ice making, and perform corresponding alarm work according to the liquid level conditions at different heights, thereby promptly notifying the user to clean the water receiving tray 2 to prevent the material in the water receiving tray 2 from overflowing and contaminating other positions of the box body 3, thereby further improving the user's comfort and the safety of the use of electronic control components and circuits.

[0034] Preferably, the controller is also connected to the user's mobile terminal via a wireless communication module to promptly notify the user who is not on site that the situation of the water tray 2 needs to be handled, thereby improving the alarm processing efficiency and thus improving the water collection effect of the water tray 2.

[0035] Preferably, if Figures 1 to 2 As shown, the water receiving mechanism of the present invention is arranged in the middle of the cold drink machine, and a motor seat 4 and an ice making bin 5 are arranged above the supporting seat 1, a driving motor 41 is fixed in the motor seat 4, an evaporator 51 and a scraper 52 are arranged in the ice making bin 5, and the evaporator 51 is installed at one end of the motor seat 4; and a compressor 31 and a condenser 32 are arranged below the supporting seat 1. The present invention uses the supporting seat 1 as the middle supporting structure of the cold drink machine, which can optimize the layout of the overall structure of the cold drink machine in the upper and lower parts, making the structure of the cold drink machine more compact, small overall space and volume, and low cost.

[0036] Furthermore, in order to prevent the condensed water formed on the outer walls of both sides of the ice making bin 5 from falling from the bottom of the ice making bin 5 to outside the area of ​​the water receiving tank 21, that is, falling to other positions of the box body 3, thereby increasing unnecessary cleaning steps. Figures 5 and 6As shown, the ice making bin 5 is cylindrical, and the slot width of the water receiving groove 21 is greater than or equal to the bottom width of the ice making bin 5, so that the condensed water can stably fall into the water receiving groove 21 when falling from the bottom of any side of the ice making bin 5, thereby facilitating the collection of the condensed water to be collected, eliminating unnecessary cleaning procedures, and improving the user's comfort. In other embodiments, the slot width of the water receiving groove 21 can also be greater than or equal to the width of the ice making bin 5, so as to ensure that the materials dropped from the ice making bins 5 of different regular shapes can stably fall into the water receiving groove 21, thereby also realizing the material collection function.

[0037] Preferably, if Figure 4 and Figure 6 As shown, the two side edges of the water receiving tray 2 are respectively provided with slide rail flanges 22, and the slide rail flanges 22 are respectively in contact with the two side inner walls of the slide rail groove 11. The slide rail flanges 22 can reduce the contact area with the slide rail groove 11, thereby reducing the contact friction, improving the sliding installation and sliding removal effect of the water receiving tray 2, and thus facilitating the user to disassemble, install and use.

[0038] In order to limit the position of the water tray 2. Figures 3 to 4 As shown, the water receiving tray 2 is provided with first abutting portions 23 on both sides of one end away from the motor seat 4, and the second abutting portions 13 adapted to the first abutting portions 23 are provided on both sides of the upper part of the through opening 12. When the water receiving tray 2 slides into the slide rail groove 11, the first abutting portion 23 abuts against the second abutting portion 13, which can limit the water receiving tray 2 horizontally inward and vertically upward. The first abutting portion 23 is a first inclined portion, and the second abutting portion 13 is a second inclined portion, but this is not a limitation. In other embodiments, as long as the adaptation and abutment of the first abutting portion 23 and the second abutting portion 13 can achieve the above-mentioned limiting effect, such as mutually adapted stepped portions or semicircular portions, etc., there are no excessive restrictions here.

[0039] Preferably, the water tray 2 is used for guiding the installation. Figures 3 to 4 As shown, the inner walls of both sides of the end of the slide rail groove 11 close to the through opening 12 are respectively provided with horizontal limit parts 14, and the horizontal limit parts 14 are respectively matched and abutted with the two end parts of the water receiving tray 2 below it. When the water receiving tray 2 is inserted from the through opening 12, the water receiving tray 2 abuts against the inner wall of the slide rail groove 11 and its space in the vertical direction is limited by the horizontal limit parts 14, so that the water receiving tray 2 slides into the slide rail groove 11 along the horizontal direction, so as to realize the guiding installation function of the water receiving tray 2.

[0040] In order to realize the quick fixing, disassembly and installation of the water tray 2 and the slide rail groove 11. Figures 3 to 4As shown, the water receiving tray 2 is fixedly connected to the slide rail groove 11 by means of a snap-on method. The inner walls on both sides of the through opening 12 of the slide rail groove 11 are respectively provided with elastic snap-on parts 15, and snap-on grooves 24 adapted to the elastic snap-on parts 15 are respectively provided at both ends of the water receiving tray 2. When the water receiving tray 2 is installed, by inserting the water receiving tray 2 into the slide rail groove 11, the elastic snap-on parts 15 of the slide rail groove 11 are snap-connected with the snap-on grooves 24 of the water receiving tray 2, thereby realizing a quick fixed connection between the two; when the water receiving tray 2 is disassembled, the water receiving tray 2 only needs to be pulled to separate the snap-on grooves 24 from the elastic snap-on parts 15, so that the water receiving tray 2 can be quickly disassembled, thereby meeting the user's needs for convenient use.

[0041] Preferably, if Figure 1 , Figure 3 and 5 As shown, a mounting groove 16 is provided in one end of the support seat 1, and the slide rail groove 11 is provided in the mounting groove 16. The tops of both sides of the mounting groove 16 near the motor seat 4 are respectively provided with limit abutment blocks 17; and the two sides of the ice making bin 5 are respectively provided with positioning blocks 53, and the positioning blocks 53 abut against the end of the limit abutment block 17 away from the motor seat 4 and abut against the top of one side of the mounting groove 16. When the ice making bin 5 is installed on the motor seat 4, the positioning blocks 53 on both sides of the ice making bin 5 abut against the corresponding limit abutment blocks 17 on the support seat 1, so as to play a horizontal inward limiting role, so as to prevent one end of the ice making bin 5 from being excessively pressed on the motor seat 4 during installation; at the same time, the positioning blocks 53 on both sides of the ice making bin 5 also abut against the tops of both sides of the mounting groove 16, so as to play a supporting role for the ice making bin 5, so as to facilitate the disassembly and installation of the ice making bin 5.

[0042] Furthermore, the inner walls of both sides of the end of the installation groove 16 away from the motor seat 4 are respectively provided with introduction limit grooves 18, the introduction limit grooves 18 are located above the water receiving tray 2, and the introduction limit grooves 18 are provided with a limit portion 19 at one end close to the motor seat 4; the bottom sides of the ice making bin 5 are respectively provided with sliders 54 adapted to the introduction sliding grooves, the sliders 54 slide into the introduction limit grooves 18 and abut against the limit portion 19. When the ice making bin 5 is installed, the sliders 54 on both sides of the ice making bin 5 will slide into the introduction limit grooves 18 respectively, so that the ice making bin 5 moves along the introduction limit grooves 18 toward the motor seat 4. When it moves to the desired position, the sliders 54 will abut against the limit portion 19, further playing a horizontal inward limit role for the ice making bin 5, and avoiding excessive pressing of one end of the ice making bin 5 on the motor seat 4 during installation. Among them, the width of the slide rail groove 11 is greater than the width of the ice making bin 5 and the water receiving groove 21, and at least part of the structure of the ice making bin 5 (such as the lower part or bottom of the ice making bin 5) is located in the slide rail groove 11, so that the liquid dropped from the ice making bin 5 can fall into the water receiving groove 21 more stably, thereby improving the material collection effect. For example, when the bottom of the ice making bin 5 is located in the installation groove 16, the distance between it and the water receiving tray 2 can be shortened, the splashing height of the material when it falls can be reduced, and the material can be prevented from splashing out of the water receiving groove 21, which is conducive to the ice or liquid flowing out of the ice making bin 5 from the bottom position to fall into the water receiving tray 2 quickly when disassembling, and the condensed water formed by the ice making bin 5 during operation can all fall into the water receiving tray 2 quickly, thereby improving the access collection effect of the water receiving tray 2, and then effectively preventing the outflowing liquid from falling to other positions of the box body 3, reducing the cleaning process, improving the user's comfort, and improving the safety of the use of electronic control components and circuits.

[0043] like Figure 7 As shown, the present invention also provides a liquid level detection method for a water receiving mechanism, which is applied to the above-mentioned water receiving mechanism, and the method comprises the following steps:

[0044] S101, during ice making operation, the controller acquires in real time liquid level signals detected by a plurality of liquid level detection devices, wherein the liquid level signals include a first liquid level signal and a second liquid level signal of different heights;

[0045] Specifically, when ice is being made, as the evaporator in the ice making bin makes ice, condensed water is formed on the outer wall of the ice making bin due to the temperature difference, and the condensed water will fall into the water receiving tank of the water receiving tray. A plurality of liquid level detection devices are arranged at different positions on the upper part of the water receiving tank, wherein the first liquid level detection device is used to detect the warning liquid level of the water receiving tank and generate a first liquid level signal, and the second liquid level detection device is used to detect the alarm liquid level of the water receiving tank and generate a second liquid level signal.

[0046] It should be noted that the alarm level is the top position of the water tank. When the second level detection device at this position triggers the level signal, it means that the material in the water tank is about to overflow and the user needs to clean it up as soon as possible. The warning level is located below the alarm level, and the distance between the two can be set according to actual needs. When the first level detection device at this position triggers the level signal, it means that the material in the water tank has reached the warning level, which serves as a warning to the user, who can clean it up or clean it up slowly when he has time.

[0047] S102, the controller determines whether the first liquid level signal is a first preset liquid level signal. If it is determined to be yes, it means that the liquid level in the water receiving tank has reached the warning liquid level, and step S103 is executed. If it is determined to be no, the controller returns to step S101;

[0048] It should be noted that when the first liquid level signal detected by the first liquid level detection device is the first preset liquid level signal, it means that the material liquid level in the water receiving tank has reached the warning liquid level. At this time, it is necessary to further determine whether the material liquid level in the water receiving tank has also reached the alarm liquid level so as to perform accurate alarm processing according to the specific liquid level conditions.

[0049] S103, the controller determines whether the second liquid level signal is the second preset liquid level signal. If it is yes, it means that the liquid level in the water tank has reached the alarm water level, and the sound and light alarm device is controlled to perform a long-time alarm, and a liquid level alarm message is sent to the user's mobile terminal through the wireless communication module. If it is no, it means that the liquid level in the water tank only exceeds the warning liquid level, and the sound and light alarm device is controlled to perform a short-time alarm, and a liquid level warning message is sent to the user's mobile terminal through the wireless communication module, and then returns to step S101.

[0050] It should be noted that when the second liquid level signal detected by the second liquid level detection device is the second preset liquid level signal, it means that the current material liquid level in the water receiving tank has also reached the alarm liquid level, and the material in the water receiving tank is about to overflow. At this time, the controller controls the sound and light alarm device to perform a long-term sound and light alarm to warn the user on site to clean the docking water tray in time; it can also send a liquid level alarm message to the user's mobile terminal by wireless mode, and promptly inform the user who is not on site to clean the docking water tray immediately. When the second liquid level signal detected by the second liquid level detection device is not the second preset liquid level signal, it means that the liquid level in the water receiving tank has only exceeded the warning liquid level, but has not yet reached the alarm liquid level, that is, it is still in a safe use state. At this time, the sound and light alarm device is controlled to perform a short-term alarm to promptly warn the user on site; it can also send a liquid level warning message to the user's mobile terminal by wireless mode to promptly inform the user of the current liquid level of the water receiving tank, and the user can clean it or clean it slowly when he is free later.

[0051] The present invention can perform corresponding detection and alarm processing work for different liquid level conditions of the water tray through the above method, so as to realize different liquid level detection and alarm functions, thereby facilitating users to handle different liquid level alarm conditions, greatly improving the alarm processing efficiency, thereby improving the water collection effect of the water tray, and further improving the user's comfort and the safety of the use of electronic control components and circuits.

[0052] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
