  We investigate theoretically quantum transport through the "charge" Kondo
circuit consisting of the quantum dot (QD) coupled weakly to an electrode at
temperature $T+\Delta T$ and connected strongly to another electrode at the
reference temperature $T$ by a single-mode quantum point contact (QPC). To
account for the effects of Coulomb interaction in the QD-QPC setup operating in
the integer quantum Hall regime we describe the edge current in the quantum
circuit by Luttinger model characterized by the Luttinger parameter $g$. It is
shown that the temperature dependence of both electric conductance $G\propto
T^{2/g}$ and thermoelectric coefficient $G_T\propto T^{1+2/g}$ detours from the
Fermi-liquid (FL) theory predictions. The behaviour of the thermoelectric power
$S=G_T/G\propto T$ in a regime of a single-channel Kondo effect is, by
contrast, consistent with the FL paradigm. We demonstrate that the interplay
between the mesoscopic Coulomb blockade in QD and weak repulsive interaction in
the Luttinger Liquid $g=1-\alpha$ $(\alpha \ll 1)$ results in the enhancement
of the thermopower. This enhancement is attributed to suppression of the Kondo
correlations in the "charge" circuit by the destructive quantum interference
effects.
