Description

Technical Field

[0001] The utility model relates to the technical field of maternal and infant products, in particular to maternal and infant equipment with heating and cooling functions. Background Art

[0002] The Chinese utility model with the announcement number CN219629394U proposes a "constant temperature milk mixer with quantitative water discharge function", which sets a fixed water outlet and a corresponding electric water pump assembly on the water-boiling base, so that the water in the kettle can be electrically pumped to the fixed water outlet of the water-boiling base for discharge. This type of milk mixer is equipped with a temperature regulation function for the water in the kettle, so that it can pump out 40℃-45℃ water suitable for milk mixing, which is convenient for milk mixing and allows babies to drink milk with a more appropriate temperature. However, when this type of milk mixer is left unused for a period of time, the temperature of the water remaining in its water outlet pipe will decrease. When it is used next time, this part of low-temperature water will cause the overall water outlet temperature to drop.

[0003] In addition, since some milk mixers boil the water and then perform constant temperature control at 40°C-45°C, it takes a long time to wait from the time the water is boiled to the time the water for milk mixing can be used. For this reason, some milk mixers have also proposed designs that can quickly cool down, such as the Chinese invention application "A cooling mother and baby water heater" with publication number CN108413603A. The temperature of the outlet water can be reduced accordingly through a water cooling structure, but when the outlet water temperature is too low, the outlet water temperature cannot be improved well. Therefore, it is necessary to design a milk mixer that can cool down and heat the water in the outlet pipe. Utility Model Content

DETAILED DESCRIPTION

[0021] 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 in 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.

[0022] See also Figure 1-3 The mother-infant device with heating and cooling functions comprises a water-boiling base 1, a kettle 2 and a connecting component 3. The water-boiling base 1 is provided with a water pump 4, a controller 5, a semiconductor cooling sheet 6 and a water inlet 7. The water inlet of the water pump 4 is connected with a water inlet pipe. The connecting component 3 is used to connect the kettle 2 with the water inlet pipe after the kettle 2 is placed at a corresponding position on the water-boiling base 1.

[0023] The water outlet of the water pump 4 is connected with the water inlet 7 through a connecting piece, and a water outlet space connecting the water inlet 7 and the water outlet of the water pump 4 is formed in the connecting piece.

[0024] The semiconductor refrigeration sheet 6 is installed on the water-boiling base or the connecting piece, and the heat exchange end of the semiconductor refrigeration sheet 6 corresponds to the connecting piece to exchange heat with the water in the connecting piece; the controller 5 is provided with a semiconductor polarity switching circuit 8, and the controller 5 controls the electrical polarity of the semiconductor refrigeration sheet 6 through the semiconductor polarity switching circuit 8.

[0025] When it is necessary to heat or cool the water in the water outlet space, the controller 5 switches the polarity of the semiconductor refrigeration plate 6 through the semiconductor polarity switching circuit 8, so that the semiconductor refrigeration plate 6 heats or cools the water in the water outlet space accordingly, which has better applicability.

[0026] After the semiconductor cooling sheet 6 is powered on, when the temperature of the heat exchange end decreases, it is usually also called the cold end; when the temperature of the heat exchange end increases, it is usually also called the hot end. The controller 5 can control the polarity of the connection of the semiconductor cooling sheet 6 through the semiconductor polarity switching circuit 8, thereby controlling the heat exchange end to be the cold end or the hot end.

[0027] As an example: when the controller 5 makes the first end of the semiconductor refrigeration film 6 the input end (connected to the positive pole) and the second end of the semiconductor refrigeration film 6 the output end (connected to the negative pole) through the semiconductor polarity switching circuit 8, the heat exchange end is the cold end; when the controller 5 makes the first end of the semiconductor refrigeration film 6 the output end (connected to the negative pole) and the second end of the semiconductor refrigeration film 6 the input end (connected to the positive pole) through the semiconductor polarity switching circuit 8, the polarity changes so that the heat exchange end becomes the hot end accordingly.

[0028] like Figure 3 As shown, in some embodiments, the semiconductor polarity switching circuit 8 includes a relay K1 for controlling the positive and negative polarity switching, and the electromagnetic coil of the relay K1 is connected to the polarity control terminal of the controller.

[0029] In some embodiments, when the electromagnetic coil of relay K1 is not energized, the positive electrode is connected to the first end of the semiconductor refrigerator 6, and the negative electrode is connected to the second end of the semiconductor refrigerator 6; when the electromagnetic coil of relay K1 is energized, the positive electrode is connected to the second end of the semiconductor refrigerator 6, and the negative electrode is connected to the first end of the semiconductor refrigerator.

[0030] In some embodiments, a temperature detection unit 12 for detecting the water temperature in the water outlet space is provided on the water heating base 1, and a signal end of the temperature detection unit 12 is electrically connected to a signal feedback end of the controller 5. The water temperature in the water outlet space can be detected by the temperature detection unit 12, for example, to detect the outlet water temperature, or to control the outlet water temperature in conjunction with power regulation of the semiconductor refrigeration sheet, or to maintain a certain temperature of the water in the water outlet space in conjunction with power regulation of the semiconductor refrigeration sheet.

[0031] like Figure 3 As shown, in some embodiments, the temperature detection unit includes a thermistor R2.

[0032] In some embodiments, a solenoid valve 13 is installed on the connecting piece to control the conduction / closure of the water outlet from the water inlet to the water pump. The controller 5 can control the opening / closing of the water outlet through the solenoid valve 13. When used in conjunction with the temperature detection unit 12, it can also be used, for example, to allow water to be discharged after the water temperature in the water outlet space reaches the preset requirements. As an example, when the water temperature in the water outlet space is detected to be between 40°C and 45°C, water can be allowed to be discharged.

[0033] In this embodiment, the connecting piece includes a water outlet pipe 9. A heat exchange assembly is arranged on the water outlet pipe 9. The heat exchange assembly includes a heat exchange main plate 10 and a heat exchange tube 11 connected to the heat exchange main plate 10. The heat exchange main plate 10 cooperates with the heat exchange end of the semiconductor refrigeration plate 6 for heat exchange; wherein the heat exchange tube 11 is wound around the water outlet pipe 9.

[0034] The semiconductor refrigeration plate 6 is connected to the heat exchange main plate 10 so that the heat exchange end of the semiconductor refrigeration plate 6 corresponds to the heat exchange main plate 10.

[0035] In some embodiments, thermal grease is applied between the heat exchange end and the heat exchange main plate 10 .

[0036] Furthermore, the heat exchange tube 11 is spirally wound around the water outlet pipe 9 .

[0037] Furthermore, the heat exchange tube 11 is spirally wound from one end of the water outlet pipe 9 close to the water inlet to one end close to the water outlet of the water pump, so that the overall heating and cooling effects are better.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
