Abstract
The present disclosure relates to a water tank arrangement. The water tank arrangement comprises a water tank connectable between an outlet of a water rinsing arrangement (1) and a water cistern (5) of a toilet, wherein the water tank arrangement comprises a water pump arranged to controllably circulate at least a portion of the water in the water tank when the temperature level within the water tank exceeds a predetermined temperature threshold limit.
Claims11
A water tank arrangement comprising a water tank connectable between an outlet of a water rinsing arrangement and a water cistern of a toilet, the water tank comprising an inlet portion connectable to the outlet of the water rinsing arrangement for receiving water from the water rinsing arrangement;
- and a first outlet portion connectable to the water cistern of the toilet;
- wherein the water tank arrangement further comprises a water temperature detecting device;
- a water circulation arrangement comprising a water pump for circulating the water in the water tank, wherein the water circulation arrangement comprises a circulation conduit extending between a first and a second portion of the water tank, the water pump being connected to the circulation conduit for directing water from the first portion towards the second portion;
- and a control unit connected to the water temperature detecting device and to the water pump the control unit being configured to:
- receive a signal from the water temperature detecting device the signal being indicative of a temperature level or a temperature distribution of the water within the water tank;
- compare the temperature level of the water with a predetermined temperature threshold limit, or compare the temperature distribution with a predetermined temperature deviation, and when the temperature level is above the predetermined temperature threshold limit or the temperature distribution is above the predetermined temperature deviation:
- control the water pump to circulate at least a portion of the water from the first portion to the second portion in the water tank.
A method for controlling a water tank arrangement, the water tank arrangement comprising a water tank connected between an outlet of a water rinsing arrangement and a water cistern of a toilet, the water tank comprising an inlet portion connected to the outlet of the water rinsing arrangement for receiving water from the water rinsing arrangement;
- and a first outlet portion connected to the water cistern of the toilet;
- wherein the water tank arrangement further comprises a water circulation arrangement comprising a water pump for circulating the water in the tank, wherein the water circulation arrangement comprises a circulation conduit extending between a first and a second portion of the water tank, the water pump being connected to the circulation conduit for directing water from the first portion towards the second portions;
- the method comprising the steps of:
- determining a temperature level or temperature distribution of the water within the water tank;
- comparing the temperature level of the water with a predetermined temperature threshold limit, or compare the temperature distribution with a predetermined temperature deviation, and when the temperature level is above the predetermined temperature threshold limit or the temperature distribution is above the predetermined temperature deviation:
- controlling the water pump to circulate at least a portion of the water from the first portion to the second portion in the water tank.
