With respect to
The slanted rim 140 creates a geometry in which a front portion of the housing 120 and receptacle 130 are lower than a rear portion of the housing 120 and the receptacle 130. The rear portion of the housing 120 below the higher portion of the slanted rim 140 includes an aperture 150 serving as an integral handle. This geometry also permits active cooling of more surface area of the beverage container, in particular, the portion of the beverage container adjacent the rear portion of the receptacle 130 while simultaneously obtaining the aesthetic benefit of displaying more of the from of the beverage container.
The lower part or base 127 of the housing 120 contains electrical and electronic components for controlling a temperature in the beverage container receptacle 130. As will be explained more fully below, positioning these components in the base of the housing 120 makes the system 100 less likely to topple by lowering its center of gravity. According to an aspect of an embodiment, the lower part 127 of the housing 120 may also include a display 160 for displaying a temperature which may be a set temperature or an actual temperature. A control 170 such as a slide switch, shown in phantom as it may not be visible, may be included for setting a temperature.
The various sensors described above make up part of an overall control system 300, one possible arrangement for which is included in the functional block diagram shown in
The communication interface 370 may include any device for communicating data to or from the CPU 320 and an outside device. For example, the communications interface 370 may include a USB interface and/or or an Ethernet interface. The communications interface 370 may additionally or alternately include a wireless interface such as a WiFi, Bluetooth, or an NFC interface.
A user interface can be implemented as software operating on a computer or as an application on a smart phone or tablet or other wireless communication device. To implement this, the communications interface 370 could be configured to interface with an external device 375 such as a wireless enabled device such as a computer, tablet, or cell phone. The user could use an application on the mobile device to control operation of the beverage container temperature control system. If the external device 375 is a wireless enabled device such as a computer, tablet, or cell phone, an application could be installed on the external device 375 and the user interface for the application could, for example, be a visual representation of a display with controls.
The control system 300 may also include various power control units 380 such as a thermal controller power control unit 382. The thermal controller power control units may use pulse width modulated control of the thermal controllers in which a duty cycle of pulses is used to control the average power supplied to the thermal controllers. The power controller 380 may also a control 384 for a gyroscopic stabilizer if one is present. The power controller 380 may also include a fan power control 386 electrically connected to control operation of the fan assembly 220. The thermal controller 382 may also include provision for reversing the polarity of the thermal control element 200 so that it heats rather than cools or vice versa. This could be useful if an excess amount of ice accumulates at the receptacle 130 which may interfere with operation or even cause a bottle to become trapped in the receptacle 130.
The sensor 395 for sensing an amount or level of liquid in a bottle inserted into the receptacle 130 may operate optically or by determining net weight, for example for measuring usage patterns. The bottle level may be indicated by an indicator, for example, a column of LEDs illuminated up to the same level as the sensed level in the bottle, or may be relayed to be read remotely, e.g., by Bluetooth or Wi-Fi to a control device such as a smart phone running an app.
The input devices 340 may include a touch screen or any other manual user interface devices used for controlling operation of beverage container temperature control system. Also connected by the bus 310 may be one or more displays 350 which may include, for example, the temperature display 160 (
The CPU 320 is also capable of selecting between multiple power inputs through a power input unit 360 which, for example, may be connected to line power 363 or a battery pack 367.
As mentioned, the CPU 320 may also be connected by the bus 310 to an operational status sensor 380 to determine, for example, operational temperature, an amount of time the device has been operated for purposes of scheduling maintenance or remaining battery life, and so on.

Ambient air is drawn into an around the heat sink at a separate location from where warm air is expelled downward from the fan in a 360 degree ring. There is a parting wall between the hot air exhaust portion and the cold air intake. Ambient air is drawn in through the front and rear of the heat sink. In some embodiments, the inside wall of the beverage container temperature control system is in thermal communication with the cold side of the Peltier element and functions as a cold sink.
According to another aspect of an embodiment, the beverage container temperature control system is supplied with various temperature sensors. For example, there may be a temperature sensor at the top end of the interior cold sink to indicate the temperature at that point. Similar temperature sensors could be positioned at the middle, that is, halfway up the beverage container temperature control system or the middle of the cold sink and at the bottom end of the cold sink. The beverage container temperature control system can also include sensors on an outside casing to measure ambient temperature, humidity, light intensity, wind speed, and atmospheric pressure. As indicated, there may also be a temperature sensor at heat sink and there may be a temperature sensor at the air inlet.
For some applications, it may be desirable to avoid the use of a fan at all. For such applications, the inner portion of the device may be adapted to function as a cold sink in thermal contact with the cold side of the Peltier element. The outer casing may then be arranged to act as a heat sink. Heat pipes can be placed in the outer casing to promote better heat transfer. A vacuum may be maintained between the inner the walls of the inner chamber and the outside walls in order to reduce heat flow between the cold sink and the heat sink.
According to another aspect of an embodiment, the outer casing may be provided with fins to promote better heat transfer between the outer casing acting as a heat sink and the ambient air.
In accordance with another aspect of an embodiment, the beverage container temperature control system is dimensioned to have a diameter of at least 120 millimeters.
