Abstract
A heating circuit for a soybean milk machine comprises a heating tube, wherein a fuse type temperature fuse is connected in series between one end of the heating tube and a control circuit, and a voltage-holding type non-self-resetting thermal breaker is connected in series between the other end of the heating tube and the control circuit. The utility model has the advantages that: through 1 voltage-holding type non-self-resetting thermal circuit breaker of establishing ties, make the product accord with the safety standard requirement, simultaneously in customer's in-service use, after the product unusual dry combustion leads to the protection, because the preferential protection of voltage-holding type non-self-resetting thermal circuit breaker makes the product keep the protection state before the outage always, accord with the safety requirement, simultaneously after the product pulls out the electricity cooling, because the power failure of voltage-holding type non-self-resetting thermal circuit breaker resets, the product can reuse again, need not any maintenance, greatly satisfy customer's use.
Description
Technical field
The utility model relates to the heater circuit that a kind of machine for kitchen use is used, especially a kind of soy bean milk making machine heater circuit.
Background technology
Soy bean milk making machine is universal as small household appliances, and consumer just can obtain the good to eat soya-bean milk of nutrition very easily.The mode of heating of existing soy bean milk making machine mostly is bottom-heated; existing structure heating pipe two ends connect respectively a Self-resetting temperature controller and a Fuse Type fuse; Self-resetting fuse protection point temperature is lower than fuse wire; when temperature reaches Self-resetting protection point; Self-resetting fuse disconnects; heating stops, and heat-generating pipe temperature is during lower than Self-resetting fuse, and heat-generating pipe continues heating.In cup, do not have water time, can cause the dry combustion method repeatedly of cup bucket, product is caused to damage.
The existence of Self-resetting temperature controller causes after product protection can also sustained restoration heating, meets in GB4706.19 19.4 requirement by the temperature controller protection of Self-resetting, does not meet in 24.101 for the requirement of non-automatic-reset protective device, has potential safety hazard; The frequent in actual use situation that occurs causing due to dry combustion method in various degree model machine damage, produces too much unnecessary maintenance.
Summary of the invention
The utility model provides a kind of soy bean milk making machine heater circuit that uses safety, reduces maintenance cost.
The technical solution adopted in the utility model is:
A kind of soy bean milk making machine heater circuit, comprise heat-generating pipe, between one end of described heat-generating pipe and control circuit, be in series with Fuse Type Thermal Cutoffs, it is characterized in that: between the other end of described heat-generating pipe and control circuit, be in series with voltage maintenance non-automatic-reset thermal circuit beraker.
Operation principle of the present utility model: when consumer's maloperation or control circuit break down, when heat-generating pipe temperature can reach the temperature spot of voltage maintenance non-automatic-reset thermal circuit beraker, voltage maintenance non-automatic-reset thermal circuit beraker disconnects, cut off the large current loop of heat-generating pipe electric heating, heat-generating pipe reduces heating power, the PTC circuit of electric current in voltage maintenance non-automatic-reset thermal circuit beraker, PTC temperature increases, its resistance increases, make voltage maintenance non-automatic-reset thermal circuit beraker keep open-circuit condition, realize and stop for a long time heated condition, heat-generating pipe temperature is declined, protection product safety.Product pulls out after power supply, the inside PTC current vanishes of voltage maintenance non-automatic-reset thermal circuit beraker, and temperature reduces, and its resistance is reduced to normal condition, and inner switch closure, does not affect and reuses.
The beneficial effects of the utility model are: by 1 the voltage maintenance non-automatic-reset thermal circuit beraker of connecting; make product meet safety standard requirement; simultaneously in the actual use of client; the abnormal dry combustion method of product causes after protection; due to voltage maintenance non-automatic-reset thermal circuit beraker priority protection; make product before power-off, keep guard mode always; meet safety requirements; simultaneously product pull out electricity cooling after; due to voltage maintenance non-automatic-reset thermal circuit beraker power-off restoration; product can be reused again, without any need for maintenance, greatly meets client's use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further described, but the utility model is not confined to these detailed description of the invention.One skilled in the art would recognize that the utility model contained all alternatives, improvement project and the equivalents that within the scope of claims, may comprise.
With reference to Fig. 1, a kind of soy bean milk making machine heater circuit, comprise heat-generating pipe R1, between one end of described heat-generating pipe R1 and control circuit 1, be in series with Fuse Type Thermal Cutoffs F1, between the other end of described heat-generating pipe R1 and control circuit 1, be in series with voltage maintenance non-automatic-reset thermal circuit beraker 2.
When use, heat-generating pipe R1 is arranged on soybean milk grinder bottom of the barrel.It is upper that input voltage is loaded into heat-generating pipe R1 through control circuit, and heat-generating pipe R1 starts heating, and Fuse Type Thermal Cutoffs F1 and voltage maintenance non-automatic-reset thermal circuit beraker 2 are assemblied near heat-generating pipe R1.
Operation principle of the present utility model: when consumer's maloperation or control circuit 1 break down, when heat-generating pipe R1 temperature can reach the temperature spot of voltage maintenance non-automatic-reset thermal circuit beraker 2, voltage maintenance non-automatic-reset thermal circuit beraker 2 disconnects, cut off the large current loop of heat-generating pipe R1 electric heating, heat-generating pipe R1 reduces heating power, the PTC circuit of electric current in voltage maintenance non-automatic-reset thermal circuit beraker 2, PTC temperature increases, its resistance increases, make voltage maintenance non-automatic-reset thermal circuit beraker 2 keep open-circuit condition, realize and stop for a long time heated condition, heat-generating pipe R1 temperature is declined, protection product safety.Product pulls out after power supply, the inside PTC current vanishes of voltage maintenance non-automatic-reset thermal circuit beraker 2, and temperature reduces, and its resistance is reduced to normal condition, and inner switch closure, does not affect and reuses.
