Description

A heat collecting cover for a gas stove and a cooker and a cabinet with the heat collecting cover

technical field

The invention relates to the technical field of kitchen utensils, in particular to a heat collecting cover capable of recycling heat energy and a cooker and a cabinet having the heat collecting cover.

Background technique

The burner of the currently commonly used gas embedded cooker is usually placed on the panel of the cooker. In this gas cooktop structure, the flame of the burner is completely exposed to the air during the combustion process, and the heat generated by the combustion is caused by thermal radiation or Most of the heat exchange with the air convection is lost, the available heat is greatly reduced, and at the same time it is easy to greatly increase the temperature in the kitchen. Its structure is relatively complex, which not only increases the internal temperature rise of the cooker, but also cannot fully utilize the combustion heat of the gas, resulting in a low combustion efficiency of the gas.

In addition, cabinets have been widely used now, especially in commercial houses. Due to the small space of the kitchen and the relatively poor ventilation performance, the cabinets in the kitchen are mostly sealed structures. After the kitchen utensils are cleaned, there are often residues on the kitchen utensils. Water, water will be put into the cabinet along with the kitchen utensils. Accumulation for a long time will cause moisture in the cabinet, which will easily lead to the breeding of bacteria and other harmful substances. It must be cleaned regularly, which is time-consuming and laborious. An important reason for the humidity in the cabinet, for this reason, the existing products have proposed some solutions for the problem that the cabinet is prone to mildew. Such an automatic dehumidification cabinet is provided, which includes a casing and a sealed door that seals the casing, the inner upper end of the casing is an exhaust chamber, an exhaust fan is arranged in the exhaust chamber, and the inner and lower end of the casing is an installation chamber; the intake fan in the automatic dehumidification cabinet is provided. It is used to introduce dry air from the outside. The heating chamber heats the dry air through the built-in heating device, and then sends the heated air into the interlayer and flows into the inner tank. The built-in exhaust fan in the exhaust chamber draws out the hot air. Let the hot air in the inner tank flow for heating and drying, and the humidity sensor in it monitors the humidity in the shell at all times. The automatic dehumidification cabinet can not only dehumidify automatically, but also is easy to operate. However, based on the design of modern cabinets, such as a Chinese utility model patent "A New Cabinet" with patent number ZL201521112647.X (authorized announcement number CN205390842U) discloses a cabinet that combines an induction cooker, a cleaning device, etc., and similarly existing The built-in cooker in the cabinet is also combined with the cabinet, but the cabinet below the cooktop is usually a closed structure. On the one hand, it is easy to cause the above-mentioned problem of cabinet mold. At the same time, during the use of the cooker, the heat generated by combustion will be due to heat radiation. Waste, for this reason, there is a need for a cabinet that can effectively utilize the heat generated by the stove for use by the cabinet and play a dehumidifying role.
