Commercial gas stove waste heat utilization device

Abstract

The invention relates to a commercial gas stove waste heat utilization device which is composed of a water-jacket-type hearth, a water storage box, a hearth water inlet pipe, a hearth water outlet pipe, a water outlet valve, a ball float valve and a cold water inlet, wherein the partial waste heat which is not utilized by the cooking among the heat generated by gas combustion is absorbed by water in a hearth through the water-jacket-type hearth; after the water is heated in the hearth, the water automatically flows from the hearth water inlet pipe into the hearth water outlet pipe; the hearth water outlet pipe is connected with a hot water box; the hearth water inlet pipe is communicated with a cold water box; the upper parts of the hot water box and the cold water box are separated by a thermal-insulation baffle plate; the bottoms of the hot water box and the cold water box are communicated. Thus, under the flowing of the water in the hearth, the water in the cold water box is driven to flow into the hearth, so that the water in the hearth flows into the hot water box; the relatively cold water at the bottom of the hot water box flows into the cold water box. Therefore, the water in water boxes is heated circularly. As a result, the heat scattered on the hearth during the gas combustion is collected effectively.

Description

Technical field: [0001] The invention belongs to the field of thermal energy engineering, and in particular relates to a waste heat utilization device of a commercial gas stove. Background technique: [0002] At present, the existing commercial gas stoves are mostly made of solid materials such as refractory bricks or heat-resistant cast iron. The heat generated by the combustion of gas is not only partially absorbed by the bottom of the pot for cooking, but also partly absorbed by the furnace. Distributed into the kitchen air; such a large amount of waste heat is directly dissipated into the kitchen air, which not only causes a great waste of energy, but also makes the kitchen air temperature higher, and the chef's working environment is poor. Because refractory bricks absorb more heat and dissipate heat slowly, it will take a long time to cool down the hearth made of refractory bricks after the gas stove ceases fire. Invention content: [0003] The purpose of the presen...
