A hydronic heating pad includes a control unit and a blanket pad connected to the control unit. The blanket pad includes a warm water region. The control unit includes a water reservoir tank, a heating pipe, an outlet pipe, and at least one return pipe. The heating pipe, the outlet pipe, and at least one return pipe are disposed on the water reservoir tank. The outlet pipe and the at least one return pipe extend into the warm water region, whereby the outlet pipe, the at least one return pipe, and the warm water region form a circulating water channel. The outlet pipe is provided with a water pump. The at least one return pipe is provided with a temperature-sensitive solenoid valve. The blanket pad includes at least two layers of waterproof fabrics. The warm water region is a hermetic region and includes a plurality of first polygon patterns.

At least some aspects of the present disclosure feature a tubular convective system including an inflatable tubular convective device and a fixation element. The inflatable tubular convective device includes a tubular structure. In some cases, the fixation element includes a first ring, where the first ring is configured to secure a first part of the tubular convective device. In some cases, the fixation element includes a flat element and a flexible element attached to the flat element proximate to a first end of the flexible element, where the flexible element is configured to secure a first part of the tubular convective device.

At least some aspects of the present disclosure feature a tubular convective device, comprising: a blown film forming a tube when inflated, the blown film having a first portion and a second portion, wherein the first portion and the second portion are separated longitudinally, and a plurality of apertures disposed on the first portion of the blown film. At least some aspects of the present disclosure feature a tubular convective system including a plurality of tubular convective devices, where adjacent tubular convective devices are connected.

A ventilating or heating/cooling element having a first side having an air permeability of 15-800 m.sup.3/m.sup.2/h at 120 Pa. The first side is for directing an air flow toward a person. The ventilating/cooling/heating element may form or form part of a mattress, a duvet/blanket, a pillow, a sleeping bag, a seat, a clothes item or the like. A pump may be provided for providing air into the ventilating/cooling/heating element, or one or more openings may be provided for receiving air when a person is moving, such as when riding a motor cycle.

A bedding climate control apparatus that delivers, in a quiet manner, forced airflow from a fan/blower within a housing to selectively deliver tempered (heated via a thermal element) and untempered (room temperature) air through a flexible hose to bedding. The quiet manner is attained with acoustic dampening material in the path of incoming airflow to the fan/blower and by oversizing each of the components that create a pressure drop including the capacity of the fan/blower over what is needed to deliver a required amount of airflow. Temperature may be set remotely via a wireless remote control and via a protocol access enabled device.

An intelligent-identification quick-charge electric blanket includes an electric blanket body, a manual operation button module and a connecting cable for a quick charge power source. The connecting cable includes an input module, a cable body, and an output port. The input module includes an output control circuit, a main control circuit, a power supply circuit, and a USB interface. The electric blanket simplifies the structure of the electric blanket body. It is convenient for subsequent replacement of the quick charge identification function or the electric blanket body, thereby reducing the maintenance cost.

A bed covering system adapted to be used by a user to stay comfortable during sleep. The bed covering system includes a blanket and a pillowcase. The blanket has different heat retention zones of at least one section of heavy material and at least one section of lighter material. The heavy material is of material that retains body heat of the user. The lighter material is of a material that allows the escape of body heat of the user and allows circulation of body heat of the user. The heavy material has a higher weave count to trap and retain heat, and the lighter material is of thinner materials that permits more evaporation from a body of a user than the heavy material.

In accordance with one embodiment, there is provided a thermoelectric-based air conditioning system. The system includes at least a first supply air channel and a separate second supply air channel disposed in a housing. The system also includes a first thermoelectric cooler (TEC) assembly forming at least a portion of the first supply air channel and configured to independently condition air within the first supply air channel. The system further includes a second TEC assembly forming at least a portion of the second supply air channel and configured to independently condition air within the second supply air channel. The system includes a single heat exchanger configured to transfer heat with both the first TEC assembly and the second TEC assembly.

A vented blanket is provided that includes opposing first and second panels that define a cavity therebetween. A binding perimetrically bounds and joins the first and second panels. The blanket includes at least one zipper configured to move between a closed position in which air within the cavity is at least partially prevented from escaping through the binding and an open position in which air within the cavity is capable of escaping through the binding.

A warming blanket includes a metalized fabric exterior layer and an interior heating element made of a carbon fiber or carbon veil. The warming blanket has two oppositely disposed electrodes. The carbon veil includes a central portion positioned between two oppositely disposed margin areas. A temperature sensor is positioned upon the central portion of the heating element.

The warming blanket also has an electrical connector having a hub connector including a pair of spaced apart side guide rails and a guide flange. The electrical connector also has a hub assembly removably coupled to the hub connector. The hub assembly has a mounting tongue being sized and shaped to fit between the spaced part side guide rails and between the second portion of the guide flange and the mounting plate. The hub connector and hum assembly have mating electrical snaps.
