| description | PURPOSE:To perform a concurrent operation of both additional boiling function and filtering operation without any trouble through mere arrangement of a circulation port for one device in a bath tub by a method wherein a hot water supplying and filtering device is comprised of a filtering and circulating passage and an additional boiling passage, and the additional boiling passage is provided with a check valve operated under a pump suction force of hot water supplying element having an a additional boiling function. CONSTITUTION:A hot water supplying and filtering device A having an additional boiling function is operated such that bath tub water passes from within a bath tub B through a water suction port B1. by a filtering element 2 always being operated and circulates around a filtering and circulating passage 1. The water is returned back from a water discharging port B2 int tie bath tub B and then filtered. During this circulating and filtering operation, a check valve 7 is not operated with a pressure of the filtering element 2 acting against a pipe wall during rotation of a pump, so that bath tub water is not flowed into an additional boiling passage 3 and thus a stopped state of an additional boiling element 4 is kept. As the additional boiling element 4 is also operated to receive a water sucking pressure 6 of the pump in the additional boiling element 4, the check valve 7 is opened, a part of the bath tub water circulating in the filtering and circulating passage 1 is sucked into the additional boiling passage 3 and additionally boiled up, thereafter the boiled-up water is returned back again into the filtering and circulating passage 1 and then the filtering and additional boiling of the bath tub water are concurrently carried out. In addition, a water feeding pressure of a pump 6 in the hot water feeding element 4 having an additional boiling is set to be equal to or lower than a water feeding pressure of the pump 5 in the filtering element 2. |
