Description

Yogurt machine module and refrigerator

technical field

The utility model relates to a yogurt machine module and a refrigerator.

Background technique

Yogurt is a kind of milk product that is made from fresh milk, after pasteurization and other sterilization, beneficial bacteria (starter) are added to the milk, fermented, and then cooled. Yogurt not only retains all the advantages of milk, but also develops its strengths and circumvents its weaknesses in some aspects through processing, becoming a nutritional and health product more suitable for human beings. In order to prolong the shelf life or adjust the taste, all yogurt products currently on the market have additives.

In order to ensure food safety, modern families usually use small-scale yogurt machines to make fresh yogurt by themselves. The fermentation process of yogurt can be divided into three stages: pre-fermentation, fermentation and refrigeration. The stage before fermentation is to heat the fresh milk added with starter to the fermentation temperature; in order to ensure the quality of yogurt and reduce the growth of harmful microorganisms during the heating process before fermentation, it is best to make the temperature of the milk reach the fermentation temperature as soon as possible. After the fermentation is completed, the temperature of the yogurt should be lowered as soon as possible to prevent the yogurt from continuing to ferment, which will increase the acidity of the yogurt and affect the taste.

After the yogurt machine ferments the yogurt, it needs to be kept in a low-temperature state in time, and the refrigerator is a commonly used low-temperature refrigeration device in the family. At present, the yogurt is basically transferred from the yogurt machine to the refrigerator for storage after home-made yogurt. A kind of refrigerator that can be used for making yogurt is also provided on the market at present. The refrigerator capable of making yogurt realizes making yogurt by setting a yogurt machine module in the refrigerator.

The existing yogurt machine or the yogurt machine module is heated by local ceramic sheets, and the heating part with the ceramic sheets is directly in contact with the yogurt bucket. Since the temperature of the heating part can reach about 70-80°C, the temperature rises quickly, and the temperature rises slowly at the part without ceramic sheets, which leads to uneven heating of the milk in the yogurt bucket and affects the fermentation quality of yogurt. At the same time, due to only local heating, the required heating time is long, and the yogurt bacteria resurrection cycle is long, which will also affect the quality of yogurt, and the long heating time will also lead to increased energy consumption.

The shell 51 is movably installed on the refrigerator door body 21 . The outer shell 51 includes a rear shell 511 covering the inner tank 52, an upper shell 512 and a lower shell 513 arranged on the upper and lower sides of the rear shell 511, and arranged on the left and right sides of the rear shell 511. side housing 514 . The side housing 514 is provided with a card slot 515, corresponding to this, the refrigerator door 21 is provided with a card block (not shown), through the cooperation of the card slot 515 and the card block, so that the yogurt machine module 5 is fixed on the door body 21 of the refrigerator compartment. The front side of the outer casing 511 is a casing opening 516 covered by the yogurt machine door 56 .

The inner container 52 is made of metal material. The inner container 52 includes an inner container opening 521 covered by the yogurt machine door body 56, a rear wall 522 arranged opposite to the yogurt machine door body 56, a top wall 523 and a bottom wall arranged on the upper and lower sides of the rear wall 522 524 , and side walls 525 located on the left and right sides of the rear wall 522 . Described yogurt machine door body 56 is surrounded with back wall 522, top wall 523, bottom wall 524 and side wall 525 to form fermentation space 526, and the wall body of fermentation space 526 is formed by liner 52 and yogurt machine door body 56 (ie yogurt The door body 56, the rear wall 522, the top wall 523, the bottom wall 524 and the side wall 525 form the wall body of the fermentation space 526). The inner container 52 has a wavy inner surface facing the yogurt bucket 55 , that is, the inner surfaces of the rear wall 522 , the top wall 523 , the bottom wall 524 and the side wall 525 are wavy. The heating device 54 is arranged on the outer surface of the inner container 52 , specifically on the outer surfaces of the rear wall 522 , the top wall 523 , the bottom wall 524 and the side wall 525 . The heating device 54 is a heating wire. Because the inner surfaces of the rear wall 522, the top wall 523, the bottom wall 524 and the side wall 525 are wavy, the heat transfer surface is increased, the heating rate of the fermentation space 526 is improved, and the resurrection time of the yogurt bacteria is shortened, thereby Shorten the time to make yogurt.

The yogurt machine door body 56 includes an inner panel 561 , a door shell 562 opposite to the inner panel 561 , and a heat insulating material 563 filled between the inner panel 561 and the door shell 562 . A buckle 564 protrudes from the top of the inner board 561 . The inner board 561 is the wall body of the fermentation space 526 . The inner surface of the inner board 561 facing the yogurt tub 55 is corrugated. The inner board 561 is made of metal material. The inner container opening 521 of the inner container 52 is provided with a yogurt machine door seal 528 to improve the sealing performance of the yogurt machine module 5 .

In other embodiments, the door body 56 of the yogurt machine is covered with a heating device 54 (such as a heating wire). At this time, the six walls of the fermentation space 526 are all provided with heating wires 54, so as to facilitate the heating of the fermentation space 526. Evenly heated, and can shorten the heating time. And the inner surface of liner 52, the inner surface of inner board 561 are wave-shaped, thereby increased heat transfer surface, further improved the temperature rise rate of fermentation space 526, shortened the resurrection time of yogurt bacteria, thereby shortened the time for making yogurt time. The heating device 54 can also be a heatable film or the like.

A heat insulating pad 529 is disposed inside the inner container 52 , and the heat insulating pad 529 is disposed on the bottom wall 524 of the inner container 52 . The yogurt bucket 55 is placed in the fermentation space 526 . Fresh milk to be fermented or fermented yogurt is filled in the yogurt barrel 55 . The yogurt bucket 55 is not in contact with the heating wire 54, so as to prevent the temperature of the part of the yogurt bucket 55 in contact with the heating wire 54 from being too high, thereby causing the yogurt bacteria in the yogurt bucket 55 to lose activity.

The bottom 551 of the yogurt bucket 55 is placed on the heat insulation pad 529, and the yogurt bucket 55 is supported by the heat insulation pad 529, so that the bottom 551 of the yogurt bucket 55 does not contact the bottom wall 524 of the inner container 52, while other parts of the yogurt bucket 55 The barrel surface 552 is not in contact with the liner 52 and the yogurt machine door 56, thereby preventing the yogurt barrel 55 from being heated unevenly, that is, part of the temperature is too high, causing the yogurt bacteria close to the high temperature in the yogurt barrel 55 to lose activity. Compared with the embodiment without heat insulation pad 529, the yogurt bucket 55 is in direct contact with the inner container 52. Since the heating wire 54 is arranged on the inner container 52, after the bottom 551 of the yogurt bucket 55 contacts the inner container 52, the heating wire 54 directly The heat is transferred to the yogurt barrel 55 through the inner container 52, so that the temperature of the bottom 551 of the yogurt barrel 55 is higher than that of other barrel surfaces 552, and the yogurt bacteria close to the bottom 551 in the yogurt barrel 55 lose their activity. In this embodiment, the heat insulation pad 529 is disposed on the bottom wall 524 of the inner container 52 , and in other implementations, the heat insulation pad 529 may be disposed on the bottom of the yogurt bucket 55 .
