DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 5 As shown, an automatic refrigerated yogurt machine includes an outer shell 1, an inner pot 4 and a heat preservation layer 5. The bottom of the outer shell 1 is detachably connected to a bottom shell 2 by screws or buckles, and a placement plate 3 is fixedly connected to the inside of the outer shell 1. The inner pot 4 is arranged inside the outer shell 1, and the bottom is fitted with the placement plate 3. The placement plate 3 is used to place the inner pot 4, and the inner pot 4 is used to place yogurt. The heat preservation layer 5 is arranged between the inner pot 4 and the outer shell 1. The setting of the heat preservation layer 5 plays a heat preservation role, ensuring that the inner pot 4 and the outer side have a heat insulation effect during the refrigeration, heating or constant temperature process. The yogurt machine also includes a TEC chip 8 and a heat dissipation structure;

[0027] A mounting groove 7 is provided at the bottom of the placement plate 3, and a TEC chip 8 is installed in the mounting groove 7 and extends to the bottom of the placement plate 3. The top of the TEC chip 8 is in contact with the inner pot 4. A control circuit component 16 is also provided inside the outer shell 1. The control circuit component 16 includes a TEC controller and a switch controller. The TEC controller may be an ADN883X series controller, which can control the direction of current passing through the TEC, thereby accurately adjusting the temperature, so that the control circuit component 16 can control the working state of the TEC chip 8.

[0028] The working principle of the above-mentioned TEC chip 8 is the Peltier effect, which can produce a cooling effect on one side of the chip and a heating effect on the other side. By controlling the magnitude and direction of the current flowing through the TEC chip 8, precise control of the temperature of the cooling end and the heating end can be achieved. For example, by changing the direction of the current, the roles of the cooling and heating ends can be changed, so that the original cooling end becomes the heating end, and vice versa. The TEC chip 8 belongs to the prior art and will not be elaborated here. The TEC chip 8 can be used to cool or heat yogurt.

[0029] The heat dissipation structure is disposed inside the housing 1 and cooperates with the TEC chip 8 , and the control circuit component 16 is electrically connected to the heat dissipation structure.

[0030] By providing a TEC chip 8 to replace the cooling module and the heating module in the existing yogurt maker, the cooling and heating functions of the yogurt can be realized by changing the direction of the current, thereby achieving the same effect while simplifying the internal components of the yogurt maker, making the installation simple and convenient, and having fewer assembly parts, thereby reducing the cost of mold and whole machine production and assembly, thereby reducing the overall size of the yogurt maker for easy storage.

[0031] In some specific embodiments, such as Figure 3 or Figure 5 As shown, in order to facilitate the heat dissipation of the TEC chip 8, the heat dissipation structure includes a heat dissipation substrate 9 and a fan 12. The heat dissipation substrate 9 is fixedly connected to the bottom of the TEC chip 8. A number of vertical heat dissipation wings 10 are evenly distributed on the bottom of the heat dissipation substrate 9, and the heat dissipation wings 10 are wavy plate-shaped. The wavy design can further increase the contact area between the heat dissipation wings 10 and the ambient air. The channel formed between adjacent heat dissipation wings 10 plays a role in guiding wind, and at the same time can increase the heat dissipation area and improve the heat dissipation effect. The fan 12 is connected to the top of the bottom shell 2, and the position of the fan 12 and the heat dissipation substrate 9 are aligned. The fan 12 is electrically connected to the switch controller of the control circuit component 16. When the side of the TEC chip 8 away from the inner pot 4 is the heating end, the fan 12 is controlled to turn on, and a number of air inlets 13 are opened on the bottom shell 2. A number of air outlets 14 that match the heat dissipation wings 10 are distributed on the side wall of the outer shell 1. Through the channel formed between adjacent heat dissipation wings 10, the heat of the heat dissipation wings 10 is quickly discharged from the air outlet 14 to prevent the heat from circulating inside the outer shell 1 and affecting the heat dissipation effect.

[0032] In some specific embodiments, such as Figure 5 As shown, in order to increase the heat dissipation efficiency of the heat dissipation fins 10, a plurality of heat conducting sheets 11 are connected to one end of each heat dissipation fin 10 away from the heat dissipation substrate 9, and the heat conducting sheets 11 serve to increase the contact area with the air.

[0033] In some specific embodiments, such as Figure 4As shown, in order to facilitate the control of the temperature inside the inner pot 4, a temperature sensor is also provided inside the outer shell 1. The temperature sensor is used to measure the temperature inside the inner pot 4. The temperature sensor transmits the detected temperature to the control circuit component 16. The control circuit component 16 adjusts the temperature value of the TEC chip 8, thereby facilitating the heating or refrigeration temperature control of the yogurt.

[0034] In some specific embodiments, such as Figure 3 As shown, in order to provide a closed space for yogurt fermentation, a cover cap 6 that engages with the inner pot 4 is provided on the top of the outer shell 1 .

[0035] In some specific embodiments, such as Figure 2 As shown, in order to enhance the stability of the yogurt maker, a plurality of anti-slip seats 15 are distributed at the bottom of the bottom shell 2.

[0036] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0037] When in use, milk and yogurt starter are placed in the inner pot 4, and the cap 6 is closed on the inner pot 4. The corresponding end of the TEC chip 8 is energized by the control circuit, so that the side close to the inner pot 4 releases heat, and the heating end transfers the heat to the inner pot 4 for heating. The control circuit component 16 and the temperature sensor control the temperature of the inner pot 4, first quickly heating it to 40 degrees Celsius, and then steadily heating it to 42 degrees Celsius, and then stabilizing it at 42 degrees Celsius for insulation.

[0038] When the temperature is kept warm for the set time, the control circuit component 16 changes the current direction of the TEC chip 8, so that the original heating end becomes the cooling end, so that the fermented yogurt can be automatically refrigerated, and the original cooling end becomes the heating end, that is, the side close to the heat dissipation substrate 9 is heated. The heating end of the TEC chip 8 at this time transfers the heat to the heat dissipation substrate 9, and then transfers the heat to the heat dissipation fins 10. When the current direction is changed, the control circuit component 16 controls the heat dissipation component to work, and the fan 12 works to blow air on the heat dissipation fins 10 for heat dissipation. The fan 12 drives the air to enter from the air inlet 13, and is discharged from each air outlet 14 through the channel formed by adjacent heat dissipation fins 10. The heat dissipation component can quickly reduce the temperature of the inner tank thermal conductive sheet 11 on the one hand, and on the other hand, it can prevent the hot end of the TEC chip 8 from overheating and damaging the internal TEC chip 8 components.

[0039] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
