Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
Apparatus to circulate and heat liquid, such as water, which apparatus includes an incorporated or separate source of heat (2) and a liquid inlet pipe (10) and a liquid outlet pipe (12), and inside which apparatus is arranged, connected to the outlet pipe (12), a preferably spiral pipe (11) for heating the liquid to its final temperature, characterized by that the inlet pipe (10) and the outlet pipe (12) are each equipped with a back-pressure valve (13, 14), and that inside the apparatus, between the inlet pipe (10) and the spiral pipe (11) is installed an element (7) comprising a liquid space (8) with a direct connection to the inlet pipe (10) and the spiral pipe (11) and, connected with said space, a vaporizing space (9) which quickly vaporizes the liquid.
Claim 2
Dependent Claim
131 words
Apparatus to circulate and heat liquid, such as water, which apparatus includes an incorporated or separate source of heat (2) and a liquid inlet pipe (10) and a liquid outlet pipe (12), and inside which apparatus is arranged, connected to the outlet pipe (12), a preferably spiral pipe (11) for heating the liquid to its final temperature, characterized by that the inlet pipe (10) and the outlet pipe (12) are each equipped with a back-pressure valve (13, 14), and that inside the apparatus, between the inlet pipe (10) and the spiral pipe (11) is installed an element (7) comprising a liquid space (8) with a direct connection to the inlet pipe (10) and the spiral pipe (11) and, connected with said space, a vaporizing space (9) which quickly vaporizes the liquid.
Claim 3
Dependent Claim
38 words
Apparatus in accordance with Claim 1, characterized by that both the liquid space (8) and the vaporizing space (9) are ringlike in cross-section, and that the liquid space (8) is wider and lower than the vaporizing space (9).
Claim 4
Dependent Claim
58 words
Apparatus in accordance with any of the Claims 1 and 2, characterized by that the liquid space (8) and the vaporizing space (9) are positioned partly side by side, separated from each other by a wall (22), and that the connection between them has been effected by forming an opening (16) at the bottom of the wall (22).
Claim 5
Dependent Claim
25 words
Apparatus in accordance with any of the Claims 1-3, characterized by that the inlet pipe (10) is tangentially connected to the ringlike liquid space (8).
Claim 6
Dependent Claim
40 words
Apparatus in accordance with any of the Claims 1-4, characterized by that the connection between the liquid space (8) and the spiral pipe (11) has been made at the top of the liquid space (8), at one or several places.
