1 is a partial cross-sectional view illustrating a siphon type coffee extractor according to an embodiment of the present invention.

Referring to FIG. 1, a siphon type coffee extractor 100 includes a heating means 110, a water storage port 120, an extraction port 130, and a filter 140.

The heating means 110 is for heating the water storage port 120 to boil the water contained in the water storage port 120.

The heating means 110 can heat the water storage port 120 by generating heat using an external power source. Examples of the heating means 110 using the external power supply include a heater and a halogen lamp.

The heating means 110 may generate heat by burning the fuel. Examples of the heating means 110 for burning the fuel include an alcohol lamp, a portable gas burner, and the like.

The water storage port 120 is for storing water (not shown) required for the coffee extraction process and has an inlet 122 for injecting the water above.

The water storage port (120) can be arranged to be heated by the heating means (10).

The extraction port 130 receives the coffee powder (not shown) and provides space for mixing the coffee powder with the water heated by the heating means 110.

The extraction port 130 includes a reaction tube 132 for receiving the coffee powder and a water tube 134 extending downward from the reaction tube 132. The reaction tube 132 and the water tube 134 are integrally formed.

The reaction tube 132 is opened upward. The coffee powder may be supplied through the open portion of the reaction tube 132. If water vapor in the water storage port 120 causes vapor pressure inside the water storage port 120 but the upper part of the reaction tube 132 is blocked, (134).

The water pipe 134 is inserted into the inlet 132 of the water storage port 120 and extends slightly apart from the bottom surface of the water storage port 120. Therefore, when the water is supplied to the water storage port 120, the water tube 134 is immersed in the water contained in the water storage port 120.

The water pipe 134 is extended to be slightly spaced from the bottom surface of the water storage port 120 so that when water in the water storage port 120 is boiled and a steam pressure is generated in the water storage port 120, To the extraction port 130 as much as possible.

A step 136 is formed between the reaction tube 132 and the water tube 134, specifically, at the lower end of the reaction tube 132. The filter 140 is seated in the step 136.

2 is a side view for explaining the filter shown in Fig.

1 and 2, the filter 140 includes a body portion 141, a protrusion 142, an elastic portion 143, a ring 146, a line 147, and a support 148.

The body portion 141 is seated on the step portion 136 to block the reaction tube 132 and the water tube 134 from each other. On the upper surface of the body portion 141, coffee powder contained in the reaction tube 132 of the extraction port 130 is placed. The lower surface of the body portion 141 has a shape corresponding to the shape of the step portion 136 so that the lower surface of the body portion 141 can be in close contact with the step portion 136. [

The projecting portion 142 protrudes from the body portion 141. Specifically, a plurality of protrusions 142 are provided on the lower surface of the body portion 141, and the protrusions 142 are disposed to be spaced apart from each other. The lower surface of the body portion 141 may not be in close contact with the step portion 136 due to the protrusion 142 and a gap may be formed between the extraction port 130 and the body portion 141. Water and coffee liquid can easily pass through between the extraction port 130 and the body portion 141 of the filter 140.

The coffee powder contained in the extraction port 130 can move to the water storage port 120 through the space between the extraction port 130 and the body part 141 when the projecting length of the protrusion 142 is larger than the particle diameter of the coffee powder. have. Therefore, in order to prevent the coffee powder from passing between the extraction port 130 and the body part 141, the projecting length of the protrusion 142 is preferably equal to or smaller than the particle diameter of the coffee powder.

The elastic portion 143 is connected to the lower center of the body portion 141. An example of the elastic portion 143 is a coil spring.

The elastic portion 143 may include a first elastic portion 144 and a second elastic portion 145. The first elastic portion 144 and the second elastic portion 145 have different elastic moduli. For example, the elastic modulus of the first elastic portion 144 may be smaller than the elastic modulus of the second elastic portion 145.

The ring 146 is connected to the elastic portion 143 and hooked to the lower end of the water pipe 134. The coil spring of the elastic portion 143 is stretched and the body portion 141 is pulled downward toward the water pipe 134 by the restoring elastic force of the elastic portion 143 in order to hook the loop 146 to the lower end of the water pipe 134 . Therefore, the body portion 141 and the protruding portion 142 can be in closer contact with the step portion 136, and the body portion 141 can be stably fixed.

On the other hand, when the elastic portion 143 repeatedly inflates and contracts the stable fixing of the body portion 141, the elastic force of the elastic portion 143 may be lowered. Since the elastic portion 143 includes the first elastic portion 144 and the second elastic portion 145 and the elastic force of the elastic portion 143 is lowered, the elasticity of the first elastic portion 143 144 may be lowered first. However, since the first elastic portion 145 having a relatively large elastic modulus can provide an elastic force, the elastic force of the elastic portion 143 can be maintained.

The line 147 is connected to the ring 146. The length of the elastic portion 143 and the ring 146 is shorter than the length of the water pipe 134 when the filter 140 is seated in the step 136. [ At this time, the string 147 connected to the ring 146 and extending to the outside of the water pipe 134 is pulled to hook the loop 146 to the lower end of the water pipe 134. Thus, the line 147 can be used to easily hook the loop 146 to the lower end of the water pipe 134. [

A plurality of support portions 148 are provided at the lower central portion of the body portion 141 and extend obliquely toward the lower outer side of the body portion 141. In addition, the support portion 148 has an elastic restoring force toward the outside of the lower portion of the body portion 141.

For example, the support portion 148 may be hinged to the body portion 141, and a torsion spring may be provided on the hinge shaft of the hinge coupling to provide an elastic restoring force to the outside of the lower portion of the body portion 141.

As another example, the supporting portion 148 may be hinged to the body portion 141, and the upper end of the supporting portion 148 may be fixed to the elastic portion 143. The coil spring of the elastic portion 143 is extended to lower the upper end of the support portion 148 and the lower end of the support portion 148 is lowered so that the support portion 148 It is possible to provide an elastic restoring force to the outside of the lower side of the body portion 141.

The support portion 148 has a shape in which the lower end is bent inward. Therefore, the support portion 148 can be easily inserted into the water pipe 134. [

The support 148 inserted into the water pipe 134 can be brought into contact with the inner surface of the water pipe 134 since the support part 148 has an elastic restoring force outside the lower part of the body part 141. [ Therefore, the support portion 148 restricts the movement of the body portion 141 and allows the body portion 141 to be more stably fixed.

The elastic portion 143, the ring 146, the line 147, and the support portion 148 are formed of a metal material, specifically, the elastic portion 143, the line 147, and the support portion 148. The body portion 141 and the protrusion 142 of the filter 140 are made of a ceramic material. , And iron (stainless steel). As described above, the filter 140 may be made of a material that is not contaminated by the coffee liquid. Therefore, the filter 140 can be used repeatedly without any sanitary problem. Therefore, the cost of replacing the filter 140 in the siphon type coffee extractor 100 can be reduced.

As described above, since the filter according to the present invention is made of a ceramic material and a metal material, it can be used semi-permanently without any sanitary problem. Therefore, the cost of replacing the filter can be reduced in a siphon type coffee extractor.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. It can be understood that it is possible.
