Problems solved by technology

However, since the jug can be cold, and due to the time it takes to make accurate thermal measurements with the sensors, this orientation or placement data is poor because it is slow and lags behind actual events (i.e. jug misalignment or presence)

Embodiment Construction

[0075] Such as figure 1 As shown, the espresso maker appliance 100 has a cluster head 101 and a steam wand 102 positioned above a drip tray 103 .

[0076] The drip tray 103 has a grid and its upper surface forms part of a larger flat surface or platform 104 . Platform 104 includes a useful planar surface in which opening 105 is formed. The temperature sensor assembly 106 extends through the opening. In this example, the platform is divided so that the grid 122 can be removed with the removable drip tray 103 while the sensor assembly 106 and its flat surrounding area remain stationary with the machine 100 .

[0077] figure 1 The machine 100 shown in also includes a coffee grinder outlet 107 and a portable filter cradle 108 associated with an optional internal coffee grinder with a bean hopper 109 . The machine 100 has a graphical user interface 110 on the front surface above the group head 101 .

[0078] The machine 100 includes an internal water reservoir 111 as well as t...

Abstract

A sensor assembly (106) for determining a temperature and an orientation of a jug having a bottom surface to rest on the assembly (106), the sensor assembly (106) comprising: a temperature sensor (202) for producing a temperature signal indicative of the temperature of the bottom surface, the temperature sensor (202) being urged to move in a first direction; a diaphragm (212), the diaphragm (212)being sealingly engageable with the temperature sensor (202) and a platform (104) supporting the jug, such that the temperature sensor (202) extends through the platform (104) to engage the bottom surface; a retainer (217), the retainer (217) being connected to the temperature sensor (202) and limiting movement of the temperature sensor (202) in the first direction; and a signal generator (602, 700, 800) for producing a signal when the temperature sensor (202) is moved against the urge to move in the first direction.

Description

technical field [0001] The technology involves an orientation sensor adapted to work with a temperature sensor for a metal milk steamer. Background technique [0002] Espresso making machines are known that incorporate milk froth or milk steam wands. In one popular machine configuration, the steam wand, group head for the portable filter and optional grinder outlet are located above and share a common drip pan. The drip tray provides a convenient platform in the form of a permeable grid. Some machines have a sensor that touches the bottom of the stainless steel or other metal milk steamer. When the sensor is in ideal contact with the bottom of the jug, the temperature measurement is an effective indication of the temperature of the milk as it is being heated by the steam wand. The sensed temperature can be used by the machine's processor to control steaming operations, including stopping some operations when a target temperature is reached. [0003] However, temperature ...
