The specific embodiment
The heat block 30 of electric percolator 10 shown in Figure 1.Described heat block 30 has the calandria 20 with heating surface 21.Calandria terminal 22 is provided for being connected with the back panel wiring of continuous heaters 10.Calandria 20 by means of calandria nut 23 and calandria seal 24 watertights be fixed on heat block 30.Calandria 20 has the first calandria curved portions 25, the second calandria curved portions 26 and the 3rd calandria curved portions 27.By means of calandria curved portions 25,26,27, crooked 180 ° respectively of calandrias 20, and therefore described calandria is partly parallel to himself extension as far as possible.Pipe in the length of half crooked 180 °, forms the 3rd calandria curved portions 27 thus.Therefore, the two half-unit of calandria 20 is as extending side by side " U " shape in the situation that.Described " U " shape in the first and second calandria curved portions 25,26 also crooked 180 °, but in another plane, to such an extent as to rotate 90 °, " U " shape illustrates as " Z " shape.
In addition, heat block 30 has entrance 31 and is positioned at and enters water cavity 32 near entrance 31.In the region of outlet 33, be provided with water chamber 34.The first wall 35 consisting of the first and second wall regions 36,37 in an embodiment at this separates the 3rd water section 45 and third channel section 44, to such an extent as to can guide the water on calandria 30 and described water can be heated by heated object 20.Wall is inserted in the accommodation section 80 of heat block on wall end 81.Described water can flow to the 3rd water section 45 from third channel section 42 in surrounding wall end 82.The second wall 38 separates first passage section 42 and second channel section 43, and wherein, described water can flow to second channel section from first passage section 42.Described water is heat block 30 described in percolation in the following sequence:
Entrance 31, water cavity 32, the first water section 40, first passage section 42, second channel section 43, third channel section 44, the 3rd water section 45 and the 4th water section 46, water cavity 34 and outlet 33.
By the section of water percolation, by the first, second, third, fourth, the 5th and the 6th wall, within 35,38,83,84,85 and/or 86 minutes, opened respectively.Described water section and/or channel section for example, connect by connecting portion (connecting portion 49) fluid respectively, to such an extent as to as described, water can flow to outlet 33 from entrance 31.At this, shape flow direction changes, and correspondingly changes in the present embodiment 180 °, to flow through heat block 30 to such an extent as to described water can be meandered.
In the first, third and fourth water section 40,45 and 46, do not have calandria, and described water is not heated.Heating is undertaken by the calandria 20 advantageously forming at this in first, second, and third channel section 42,43 and 44 single type.These channel sections separate with respect to water Duan Yibi, and similarly, water section separates with respect to channel section with respect to water section and channel section, to such an extent as to described water can flow.Connecting portion has corresponding open cross-section, and wherein, the cross section between water section can advantageously be different from the cross section between channel section.
Heat block consists of cupule, described cupule by around sidewall 50 and bottom 51 form.Lid 60 inserts in described cupule, and the first and second walls 35,38 are fixed in described lid.Calandria 20 is also inserted in and remains in described lid 60, and in the present embodiment, sensor 70 is for safety cut-off when overheated.The sensing element of sensor 70 stretches in the region of water flow between second channel section 43 and third channel section 44, for detecting water temperature.Sensor 70 use screws 71 are fixed on and cover on 60.
On sidewall 50, there is securing member 52,53, in particular for button or be arranged in the securing member of executive component of the unshowned cover of continuous heaters 10.
At lid, isolated covering part 62 is installed on 60, described covering part has groove 63 and with porose 65 neck 64.
Lid 60 and sidewall 50 is joined together on edge 61 and watertight seal.
Be provided with the accommodation section 72 for other sensor, in particular for the through-current capacity of water of inflow and/or the accommodation section 72 of the detecting unit of temperature 90.
In the continuous heaters of electrical adjustment, on the described position of accommodation section 72, be provided with the bidirectional thyristor of the power that affects calandria, the cold water that described bidirectional thyristor is flowed into is cooling.Flow and/or temperature-detecting device are arranged in accommodation section equally in an advantageous manner.Otherwise advantageously, be provided with at least another accommodation section.
Fig. 3 illustrates the heat block 30 in the back wall 11 that is enclosed in continuous heaters 10.Connector 113 and 111 is outwards guided through wall 12 and passes through back wall.Adapter 112 is between connector 113 and outlet 33.Adapter 110 is between connector 111 and entrance 31.Therefore, the water tube connector of continuous heaters is advantageously outwards laid.
According to another thought of the present invention, calandria 20 or calandria pipe are not to be symmetrically located in channel section 42, but are asymmetricly arranged in described channel section.When calandria has when with respect to the less spacing of level and smooth and/or straight wall 83 with respect to structurized wall, this is favourable.Calandria has with respect to structurized wall 38 spacing that is on average less than 10mm, and has with level and smooth or straight wall 83 spacing that is greater than 5mm.
According to an embodiment, the water temperature detecting in heat block by means of sensor 70, described water temperature is compared with rated temperature in adjusting device, and according to the deviation of water temperature and rated temperature, detect and set the power for the calandria 20 of continuous heaters 10, to make water reach default rated temperature.
