a heat preservation bowl

Abstract

The invention discloses a heat preserving bowl. The heat preserving bowl comprises a bowl body consisting of a heat insulating shell and an inner bowl, and a power control base which is connected with a mains supply, wherein a power socket is installed on the power control base, a heat preserving system is arranged between the inner bottom of the heat insulating shell and the outer bottom of the inner bowl, the heat preserving system comprises a ring fixed seat which is arranged at the inner bottom of the heat insulating shell and a heat storage block which is arranged in the ring fixed seat, the top end of the ring fixed seat is in close contact with the outer bottom of the inner bowl to form a closed space for guaranteeing heat emitted by the heat storage block to be transferred towards the inner bowl between the ring fixed seat and the inner bowl only, a gap is kept between the top of the heat storage block and the outer bottom of the inner bowl, a power plug is hermetically installed at the bottom of the heat insulating shell and the power plug is connected with the heat storage block. The heat preserving bowl has the advantages that since the heat emitted by the heat storage block can be transferred towards the inner bowl only, the heat preserving effect is good; since the bowl body and the power control base are separated, the bowl body can be cleaned and sterilized by using any tableware cleaning method and is convenient to clean.

Description

technical field [0001] The invention relates to a tableware, in particular to a heat preservation bowl. Background technique [0002] Existing heat preservation bowl mainly adopts hot water heating or adopts electric heating to keep food warm. The heat preservation bowl heated by hot water realizes heat preservation by injecting hot water through the volatilization and penetration of hot air. , if you want to heat again, you must pour out the uneaten food and the cooled water, and refill the water; on the other hand, the process of heating water is cumbersome and very inconvenient. The thermos bowls that adopt electric heating are various, such as utilizing electricity to charge batteries to realize heating thermos bowls. China's published invention patent application "a heat preservation bowl" (publication number: CN102824072A, application number: CN201210333920.6), the heat preservation bowl disclosed in it includes a bowl body and an electric heating block detachably in...

Problems solved by technology

The heat preservation bowl heated by hot water realizes heat preservation by injecting hot water through the volatilization and penetration of hot air. , if you want to reheat, you must pour out the uneaten food and cooled water, and refill the water; on the other hand, the process of heating water is cumbersome and inconvenient

However, this kind of heat preservation bowl has the following problems: 1) Use a power supply below 10V to charge the rechargeable battery, and then rely on the discharge of the rechargeable battery to provide heat. Since the rechargeable battery is discharged and heated by the PTC heating sheet, the voltage is low, so the heating time is longer, and The heat preservation temperature provided is low, which leads to poor heat preservation effect and cannot meet the heat preservation requirements; 2) Use an external power supply to directly supply power to the heating element, which only has the function of heating but not heat preservation. This is because the voltage is high. However, when the power is cut off, because there is no heat preservation system, it does not have the function of heat preservation, and it cannot meet the requirements of heat preservation; 2) When cleaning the heat preservation bowl, the electric heating block must be removed in advance, otherwise the electric heating block will be damaged. Frequent disassembly and assembly of the electric heating block will inevitably affect the reliability of the connection between the electric heating block and the bottom of the bowl
