Description

A kind of pressure coffee machine

Technical field

The utility model relates to a kind of pressure-type coffee machine.

Background technology

The coffee machine of selling on the existing market, the mode difference by its dissolving manufacturing coffee mainly contains dribble-feed and pressure type two big classes.Its principle of dribble-feed coffee machine is that water is heated into water vapour through heating tube under the normal pressure, and spray drops on the coffee powder, and the coffee after the dissolving flows in the cup.This class machine belongs to simple type, and cost is low, but the coffee result of extraction is poor, and taste is aromatic inadequately.To be water through water pump add its operation principle of pressure-type coffee machine is sent to heater and is heated into high pressure-temperature water, is sprayed on HTHP dissolving coffee on the coffee powder then in the molten bubble chamber of pressure, flows in the cup then.Such type is owing to adopt the water-soluble coffee of separating of high pressure-temperature, and the coffee result of extraction is good, and the taste giving off a strong fragrance is along with growth in the living standard becomes mainstream model gradually.But existing this type of pressure coffee machine (kettle), in structure with technically also have the following disadvantages:

The unlatching of the molten bubble chamber of pressure and closed work, generally be folding, locking mechanism realization by the kettle loam cake, open-and-close mechanism uses rotating shaft, crank, connecting rod or driving members such as gear, tooth bar usually, thereby mechanical component is many, commutate indirectly and the transmission complexity, mechanism is succinct inadequately, is unfavorable for reducing cost, and is not easy to disassembly, cleaning.For example: Chinese granted patent publication number CN200977073, open day is on November 21st, 2007, denomination of invention is the utility model patent and the patent publication No. CN2805612 of " structure is brewageed in the locking of coffee machine ", open day is on August 16th, 2006, and denomination of invention is the open-and-close mechanism of the molten bubble chamber of disclosed pressure in the utility model patent of " pot lid opening device ".

The utility model content

The purpose of this utility model is to overcome the above-mentioned defective of prior art, and the pressure-type coffee machine of the molten bubble chamber conveniently assemble and disassemble of a kind of coffee is provided.

In order to reach the foregoing invention purpose, the utility model has adopted following technical scheme: a kind of pressure coffee machine, comprise the water tank, water pump, heating tube and the molten bubble chamber that connect by pipeline, described molten bubble chamber comprises a loam cake, has a chamber that Open Side Down, chamber roof is installed with seal, and last tops is provided with a water inlet; One pressure dissolving chamber has a chamber that can hold coffee raw material, and its top is provided with the sealed working face that cooperates with described seal; One screen pack is arranged at bottom, described pressure dissolving chamber; And a lower cover, having the upper chamber that is used to hold described pressure dissolving chamber that an opening makes progress, chamber inner wall is provided with the positioning element that is used for fixing described pressure dissolving chamber, and its bottom is provided with the coffee delivery port; The junction of upper and lower cover body is provided with the revolving type locking button bit that cooperatively interacts.

Pressure-type coffee machine of the present utility model, its molten bubble chamber adopts loam cake and lower cover to screw the mode of locking, its folding locking only is provided with corresponding four locking button bits by upper and lower covers, the action of being opened to loam cake rotational lock or despining release by lower cover realizes, so it is simple in structure, reliable in action, use is unpicked and washed convenient, fast, can reach the purpose of saving cost again.

The specific embodiment

As shown in Figure 1 and Figure 2, Fast Heating pressure-type coffee machine of the present utility model includes:

Bottom 40: be used for supporting and installation water pump 47, water lines, electric control panel 42, reach other parts;

Base 1: waste water box 2 and waste water lid 3 are housed;

Fuselage 18;

Side plate

14,16; Top cover 15;

Water tank 7: the top is provided with water level control induced magnet is housed in tank lid 8, the case, faucet outlet valve 4 is arranged at the bottom; Water tank 7 pipelines are connected in water pump 47 water inlet pipes, and water pump 47 outlet pipes are connected in the water inlet 30 of heater 55 by pipeline, and the delivery port 60 of heater 55 is communicated with molten bubble chamber water inlet.

As shown in Figure 3, the molten bubble chamber of coffee comprises from top to bottom:

Loam cake 19: have one and be used to hold pressure dissolving chamber 26 chamber that Open Side Down, chamber roof is that the inner top of loam cake is fixed following seal by bolting element: loam cake sealing ring 20, loam cake sealing ring pressing plate 21 and loam cake shell fragment 22; Loam cake 19 outer tops are provided with water inlet 191 and four installing hole posts 192, and the lid lateral wall is provided with the outer locking button bit 193 that four bands import the inclined-plane, and two fixed screw holes positions;
