Furniture cushion water-cycle heating system and furniture cushion with the same

Abstract

The invention provides a water-circulation heating system for a furniture pad and a furniture pad which is provided with such a heating system. The heating system comprises a water storing shell and a serpentine coil. The water inlet port and the water outlet port of the water storing shell are respectively communicated with two ends of the serpentine coil, forming a circulation loop. One end of the water storing shell, at which the water outlet port is arranged, is provided with a water transporter used to drain the water from the water outlet port, and the other end on which the water inlet port is arranged is provided with an electrical conductive conduit pipe which extends to certain length into the inner cavity of the water storing shell. The electrical conductive conduit pipe and the water storing shell are insulated with one another and are respectively electrically connected with a DC electrical source, forming a pair of electrodes to heat the water transported to the water storing shell by the electrical conductive conduit pipe. Adopting the electrodes to heat, which are constituted by the water storing shell and the electrical conductive conduit pipe in the inner cavity of the water storing shell, the heating system can not radiate electromagnetic waves during the heating process. Therefore, the heating system is safe and healthy, with high heating efficiency and good effect. Meanwhile, the heating system is dispensed with the parts particularly used to construct the electrodes, therefore the heating system has the advantages of simple and compact structure, small volume and light weight.

Description

technical field [0001] The present invention relates to furniture accessories such as beds, sofas, chairs, etc. which are often directly in contact with the human body in a large area, and in particular to a water circulation heating system connected with mattresses, sofa cushions, chair backs, etc. and a furniture cushion with the system. Background technique [0002] For the sake of health care, people design to embed the cushions of furniture, such as mattresses, sofa cushions, chair backs, etc., which are often in contact with the human body with a large area, into a warm water circulation system, so that these furniture can maintain a certain temperature to achieve the purpose of human health care. [0003] Wherein the most common is the warm water circulating mattress, which generally includes a mattress body and a serpentine coil arranged in the mattress body, and a water circulation heating system that circulates and supplies warm water to the serpentine coil.

AI Technical Summary

Problems solved by technology

[0005] But the water circulation heating system of this structure and the furniture cushion with this system have following defects: 1. because adopt electric heating tube to carry out water heating, will inevitably radiate a large amount of electromagnetic waves, affect human health, and this heating technology also has Risk of fire and poor safety performance; 2. Since the heating pipe and hydraulic pump are installed in the shell, the whole device is bulky, complex and loose, and easy to leak electricity or water, posing a large safety hazar
