Description

Technical Field

[0001] The utility model relates to the field of ice making, and particularly relates to an ice making device and a cold drink machine. Background Art

[0002] A cold drink machine is a food processing device and has wide applications in the cold drink industry. The cold drink machine cools liquids such as fruit juices and dairy products to form ice crystals and make ice sand. Traditional cold drink machines include an ice making device, which includes a material storage cylinder, an evaporator and a scraper disposed in the material storage cylinder, etc. The liquid is poured into the material storage cylinder, cooled by the evaporator to form ice crystals, and then stirred by the scraper continuously to form ice sand, and finally the ice sand is discharged through an ice outlet on the material storage cylinder.

[0003] The existing ice making devices cannot obtain the ice making temperature. Some are provided with a temperature sensor on the evaporator. However, the temperature inside the evaporator is not equal to the temperature inside the material storage cylinder, especially the temperature at the ice outlet of the material storage cylinder. If the temperature at this place is too high, what may be output from the ice outlet is ice water instead of ice sand; if the temperature at this place is too low, the ice sand will turn into larger ice cubes or be too hard, blocking the ice outlet and unable to obtain the desired ice sand form.

[0004] In addition, the scraper needs to be sleeved outside the evaporator to scrape off the ice crystals formed on the surface of the evaporator. The rotating shaft of the driving mechanism needs to pass through the evaporator and be connected to the scraper to drive the scraper to rotate. Since the rotating shaft is relatively long, the existing ones are prone to unstable rotation of the rotating shaft, resulting in uneven local contact force between the scraper and the surface of the evaporator, so that the ice crystals on the surface of the evaporator cannot be scraped clean, and it is also easy to cause local damage to the scraper and the evaporator. Secondly, since the rotating shaft needs to pass through the evaporator, the existing ones have unreliable sealing structures, resulting in ice sand being easily introduced into the evaporator and causing damage, with a high maintenance rate.

[0030] Figure 3 is Figure 1 an enlarged view of part B of Detailed Embodiments

[0031] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as upper, lower, left, right, front, rear, inner and outer that appear or will appear in the text of the present utility model are only based on the drawings of the present utility model and do not specifically limit the present utility model.

[0032] See Figures 1 - 3 , the present utility model discloses an ice making device, which includes a storage barrel 2, an evaporator and a temperature detection mechanism 4. The storage barrel 2 is provided with an ice making cavity 22 and an ice outlet 21 communicating with the ice making cavity 22, and the evaporator is installed in the ice making cavity 22.

[0033] The evaporator includes a housing 1, the housing 1 is provided with an end cover 11 disposed near the ice outlet 21, and the temperature detection mechanism 4 is installed on the end cover 11 and is disposed corresponding to the ice outlet 21.

[0034] The temperature detection mechanism 4 includes a detection body 41, a detection head 42 and a connecting sleeve 43 provided on the detection body 41. The connecting sleeve 43 is disposed along the outer periphery of the detection body 41. The detection body 41 is fixedly connected to the end cover 11. Both the detection head 42 and the connecting sleeve 43 are exposed outside the housing 1, and the connecting sleeve 43 abuts against the end cover 11.

[0035] Preferably, the detection body 41, the detection head 42 and the connecting sleeve 43 are integrally formed. The connecting sleeve abuts against the end cover, strengthening the stability and reliability of the connection between the detection body and the end cover, and preventing the connection between the detection body and the end cover from loosening after the detection head is impacted by ice sand.

[0036] In the ice making device of the present utility model, the temperature detection mechanism is installed on the end cover of the evaporator housing and is disposed corresponding to the ice outlet of the storage barrel, so that the temperature at the ice outlet can be detected more accurately, ensuring that the temperature of the ice sand at the ice outlet is maintained within a certain range value, ensuring normal ice output, avoiding both the ice sand melting due to too high temperature at the ice outlet and the ice sand turning into larger ice cubes or having too high hardness, blocking the ice outlet and making it inconvenient to output ice, and ultimately unable to obtain the desired ice sand form. At the same time, both the detection head and the connecting sleeve of the temperature detection mechanism are exposed outside the housing, facilitating detection and installation; the setting of the connecting sleeve also enhances the overall strength of the temperature detection mechanism and the stability of its connection with the housing, making the installation connection more reliable and preventing the temperature detection mechanism from detaching from the evaporator due to being impacted by ice sand.

[0037] Preferably, the temperature detection mechanism 4 is an NTC temperature sensor.

[0038] Specifically, as Figure 2As shown, the end cap 11 is provided with a first mounting hole 12, and the detection body 41 is inserted into the first mounting hole 12; a sealing sleeve 44 is sleeved outside the detection body 41, and the detection body 41 is fixedly connected to the end cap 11 through the sealing sleeve 44. The sealing sleeve 44 is made of an elastic material, and the elastic material is preferably rubber or silica gel. The setting of the sealing sleeve not only makes the connection between the detection body and the end cap more reliable, but also plays a role in sealing the gap between the temperature detection mechanism and the end cap, preventing foreign objects such as smoothies from entering the housing.

[0039] Preferably, as Figure 2 shown, the sealing sleeve 44 includes a first sealing portion 441 and a second sealing portion 442. The first sealing portion 441 is disposed between the detection body 41 and the end cap 11, and the detection body 41 is threadedly connected to the end cap 11 through the first sealing portion 441; the connecting sleeve 43 abuts against the outer wall of the end cap 11 through the second sealing portion 442. The first mounting hole 12 is provided with an internal thread, and the detection body 41 is provided with an external thread. Therefore, the detection body and the end cap are threadedly connected. Since the first sealing portion is disposed between the detection body and the end cap, the detection body and the end cap respectively press the first sealing portion, making the connection between the detection body and the end cap tighter, and making the connection between the two more stable and reliable. At the same time, it plays a sealing role.

[0040] Among them, the second sealing portion 442 extends around from one end of the first sealing portion 441 and is disposed on the outer surface of the end cap 11. When the detection body and the end cap are threadedly connected, the connecting sleeve is connected to the outer surface of the end cap, and the second sealing portion is pressed tightly on the end cap, which not only enhances the stability of the connection between the temperature detection mechanism and the end cap, but also strengthens its sealing performance.

[0041] Furthermore, as Figure 1 shown, the present invention further includes a rotating shaft 3. The rotating shaft 3 is inserted through the housing 1 and is mounted on the end cap 11 through a shaft fixing assembly. One end of the rotating shaft 3 is connected to a motor (not shown in the figure). After passing through the housing 1 of the evaporator, it is connected to the scraper 10 to drive the scraper 10 to rotate. A shaft sleeve 14 is provided inside the housing 1, and a shaft cavity 141 is provided inside the shaft sleeve 14. The rotating shaft 3 is inserted into the shaft cavity 141. In order to support and hold the rotating shaft, the present invention is provided with a shaft fixing assembly on the end cap. The setting of the shaft fixing assembly prevents the rotating shaft from rotating unstably, makes the local contact force between the scraper and the surface of the evaporator balanced, is conducive to scraping the ice crystals cleanly, and also avoids local damage to the scraper and the evaporator.

[0042] As Figure 3As shown, the end cap 11 is further provided with a second mounting hole 13. The shaft fixing assembly includes a shaft support member 5 disposed inside the housing 1. The shaft support member 5 includes a fixed seat 51 fixedly connected to the end cap 11. The fixed seat 51 is provided with a shaft connection cavity 511 corresponding to the second mounting hole 13. The rotating shaft 3 is disposed in the shaft connection cavity 511 and the second mounting hole 13. The rotating shaft 3 is fixed to the end cap 11 through the fixed seat 51, and the reliability of the connection between the rotating shaft and the end cap is ensured by the fixed seat.

[0043] Preferably, as Figure 3 shown, a bearing 9 is installed in the shaft connection cavity 511. The rotating shaft 3 is connected to the shaft support member 5 through the bearing 9. The setting of the bearing reduces the friction between the rotating shaft and the fixed seat during rotation, making the rotation of the rotating shaft smoother.

[0044] Preferably, as Figure 3 shown, a shaft support sleeve 52 is provided at the bottom of the fixed seat 51. The shaft support sleeve 52 is provided with a shaft support cavity 521 corresponding to the shaft connection cavity 511. The rotating shaft 3 is disposed in the shaft support cavity 521. The setting of the shaft support sleeve can disperse the force on the fixed seat and the end cap, avoiding deformation of the end cap.

[0045] Furthermore, as Figure 3 shown, the shaft fixing assembly further includes a sealing and fixing member 6 and a sealing ring 7. The sealing ring 7 is sleeved outside the rotating shaft 3, and the sealing and fixing member 6 is sleeved outside the sealing ring 7. The sealing and fixing member 6 is fixedly connected to the shaft support member 5 to press the sealing ring 7 against the shaft support member 5. In the present utility model, the sealing and fixing member is fixedly connected to the shaft support member, and the sealing ring is clamped between the sealing and fixing member and the shaft support member, thereby playing a role in sealing the second mounting hole and preventing foreign objects such as ice sand from entering the housing.

[0046] Preferably, as Figure 3 shown, the sealing and fixing member 6 includes a gland 61 disposed outside the housing 1 and a connecting ring 62 disposed at the bottom of the gland 61. A connecting groove 512 is provided on the fixed seat 51. The connecting ring 62 is inserted into the connecting groove 512 and is threadedly connected to the fixed seat 51. Threads are provided in both the connecting ring 62 and the connecting groove 512, enabling the connecting ring and the fixed seat to be threaded, that is, the shaft support member and the sealing and fixing member are threadedly connected. The sealing ring 7 is provided with a sealing groove 71, and the gland 61 is embedded in the sealing groove 71. The gland 61 presses the sealing ring 7 against the fixed seat 51 through the connecting ring 62.

[0047] The utility model tightly connects the gland and the sealing ring through the sealing groove, which strengthens the sealing performance and also prevents the sealing ring from shifting during the installation process. The gland is close to the fixed seat by using the connecting ring, so as to press the sealing ring against the fixed seat and achieve the sealing of the second mounting hole. The coordinated setting of the shaft support member, the sealing and fixing member and the sealing ring improves the reliability of the rotating shaft sealing structure, prevents foreign matters such as ice sand from entering the evaporator and causing damage, and reduces the maintenance rate.

[0048] Preferably, as Figure 3 shown, the shaft fixing assembly further includes a gasket 8; the gland 61 includes an inner pressing part 611 provided inside the connecting ring 62 and an outer pressing part 612 provided outside the connecting ring 62. The inner pressing part 611 is embedded in the sealing groove 71, the gasket 8 is arranged between the outer pressing part 612 and the end cover 11, and the gland 61 abuts against the end cover 11 through the gasket 8. The setting of the gasket realizes the effective sealing between the shaft support member, the end cover and the sealing and fixing member. That is to say, the gland 61 is arranged on the outer side wall of the end cover 11, the shaft support member 5 is arranged on the inner side wall of the end cover 11, the sealing ring plays a role in sealing the inside of the connecting ring, and the gasket plays a role in sealing the outside of the connecting ring. Therefore, the coordinated setting of the shaft support member, the sealing and fixing member, the sealing ring and the gasket further improves the reliability of the rotating shaft sealing structure, prevents foreign matters such as ice sand from entering the evaporator and causing damage, and further reduces the maintenance rate.

[0049] It should be noted that both the sealing ring 7 and the gasket 8 are made of rubber or silica gel.

[0050] Correspondingly, the utility model also discloses a cold drink machine, including the above ice making device. The specific structure of the ice making device is as described above and will not be elaborated here.

[0051] The above is the preferred embodiment of the utility model.
