A refrigerated curling kettle

Abstract

A refrigerated ice pot comprises an outer shell and an inner liner. The outer base of the upper port of the inner liner is provided with an outer shoulder of the inner liner port. The contact surface between the outer shoulder of the inner liner port and the outer shell forms a first sealing pair, which is sealed by ultrasonic welding. The lower port of the outer shell is arranged on the upper port of the base. The connection between the two forms a second sealing pair, which is sealed by ultrasonic welding. This constitutes a double-layered pot body structure, and a refrigerant is filled between the two layers. During use, the refrigerant allows the beverage or beer in the inner liner to maintain a low temperature for a long time, meeting people's needs to drink and chat while cooling off in the hot summer. After the refrigerant has released its cold energy, the pot body and the annular ice bucket can be placed in the freezer to be frozen again. This can be repeated for long-term use. Alternatively, the refrigerant in the double-layered pot body can be emptied. The air in the double-layered pot body has a heat-insulating function, and the chilled beverage or beer added to the inner liner can also maintain heat for a longer period of time. The present invention has a simple structure, a reasonable design, and high energy efficiency.

Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and particularly relates to a refrigeration curling pot. Background Art

[0002] In the hot summer, people like to drink some iced drinks or beer to relieve the heat, and the way to quickly cool down drinks or beer is usually to add ice cubes or put them in a freezer to cool them down. Although adding ice cubes can quickly cool down, the concentration of the drink or beer will change after the ice cubes melt, and the taste is poor. Putting iced drinks or beer in a freezer will make it difficult to control the temperature, and too cold drinks or beer will be bad for the stomach and intestines. Secondly, it will not be able to maintain a low temperature for a long time after being taken out. In order to change this situation, various refrigeration ice pots have been invented in the prior art. For example, ZL201620008591.1 discloses a new type of refrigeration kettle, and ZL201320234328.0 discloses a cold drink kettle. Both refrigeration kettles can quickly cool drinks or beer and keep them at a low temperature for a long time. However, the use of a compressor refrigeration system or a semiconductor refrigeration system makes the refrigeration ice pot structure too complicated and the efficiency is not high.

The annular ice bucket is then removed and placed in the secondary depression of the base. The kettle body is then removed and placed on the bottom surface of the primary depression of the base. The plug is opened and a beverage or beer is added. Initially, due to the large temperature difference, the coolant quickly cools the beverage or beer. Once the temperature stabilizes, the coolant slowly releases its cold energy, allowing the beverage or beer to remain cold for a longer period of time, meeting people's needs for drinking and chatting while relieving the heat during the hot summer months. Compared to the prior art, the present invention has a simple structure, a reasonable design, and high energy efficiency. After the coolant has released its cold energy, the kettle body and annular ice bucket can simply be placed in the freezer again to freeze, and this cycle can be repeated for long-term use. Alternatively, the coolant in the double-layered kettle body can be emptied. The air in the double-layered kettle body provides insulation, allowing the chilled beverage or beer added to the inner liner to remain warm for a longer period of time.
