Description

The automatic taste removal preservation device of a kind of refrigerator

The utility model relates to a kind of refrigerator taste removal preservation technique field, refers to a kind of refrigerator taste removal preservation device that is installed on the refrigerator especially.

Store food especially often has peculiar smell to produce at the refrigeration indoor storage in the refrigerator, the mutual taint of odour of provision room meeting reduces food quality, influences the healthy of people, at this problem, people work out the way of various solutions, and common methods roughly has following several at present:

1, use deodorant to eliminate peculiar smell;

2, adsorbent (as active carbon) is laid in utilization in refrigerating chamber, comes floating in the refrigerating chamber air

Harmful substance adsorb, reach the effect of air in the cleaning refrigerator.

3, use covering such as preservative film, the food that needs are preserved covers sealing, and making can't between it

Taint of odour.

But above-mentioned three kinds of methods all have its shortcoming, and the method for using deodorant is because deodorant mostly is the chemical synthesis material, eat the human body harmful and unhelpful, should not use more.Adsorbent then needs often to change, and also causes the certain economic burden, and if forget replacing for the moment, then produce in the same old way and be difficult for the peculiar smell eliminated; The use transparent membrane covers, though can solve some problems, use is gone up cumbersome and effect is limited.Remove this or the like do not have a more economical effective way.

The purpose of this utility model provides a kind of brand-new and automatic taste removal preservation device of cost-effective refrigerator for people exactly, with the cold storing and fresh-keeping quality of raising food, thereby further improves people's quality of life.

Device of the present utility model is very simple, as everyone knows, if room air is stale, such as the ventilation of will opeing the window of getting up morning, more there is ventilation fan to use, the refrigerator taste removal is also like this, have only that exchange often with outside fresh air could be the most basic, solve the fresh-keeping problem of taste removal the most simply, according to this principle, the designed automatic taste removal preservation device of this refrigerator that goes out of the utility model, mainly be by blast pipe, axial flow blower, at least two ball-and-seats, air inlet pipe, members such as timer are formed, ball-and-seat is mounted on the refrigerator wall, and be to be provided with double-deck baffle plate in the ball-and-seat, and make that wherein at least one ball-and-seat is for entering air only, another ball-and-seat is the setting of discharging air only; And make the axial flow blower and the blast pipe of the external discharge air of exhaust ball-and-seat, the then external air inlet pipe of air inlet ball-and-seat, above-mentioned axial flow blower is to be communicated with an electronic timer, the commentaries on classics of the switch order Control Shaft flow fan that sends by timer when refrigerator normally uses with stop, opened once in for example per 4 hours, close after each 30 seconds, the exhaust ball-and-seat that connects together with it when the axial flow blower energising is rotated is opened baffle plate automatically under the moving air differential pressure action, gas dirty in the refrigerator is passed through: ball-and-seat → axial flow blower → blast pipe is discharged outside the refrigerator, the air inlet ball-and-seat also utilizes the effect of atm difference to open automatically subsequently, and pass through air inlet pipe, the air inlet ball-and-seat sucks fresh air, through regularly back axial flow blower outage stopping exhaust of electronic timer, row, the air inlet ball-and-seat is closed the ventilation work of finishing one-period.The utility model can utilize simple tools can be installed on the existing refrigerator wall use is provided, and also can be installed on the refrigerator when refrigerator is produced, and the cost that is increased is few, but can make refrigerator have new function.

Compared with prior art, the utility model has not only saved people and has eliminated the unusual smell fresh-keeping and need usually change the trouble that plastic fresh-keeping membrane and adsorbent, deodorant etc. are brought, and more simple economy practicality, and the better effects if that taste removal is fresh-keeping, fundamentally having improved existing refrigerator odour removing and fresh keeping technology, is to be a kind of novelty, progress and innovative design with good result of use.

Lifting specific embodiment below in conjunction with accompanying drawing further describes technology formation of the present utility model and acts on as follows:

The simple declaration of accompanying drawing:

Fig. 1: be to be generalized section of the present utility model.

Fig. 2: be electrical schematic diagram for the timer in the utility model.

Main drawing reference numeral explanation:

1 ... blast pipe 2 ...

axial flow blower

3,4 ... ball-and-seat

5 ... air inlet pipe 6

... refrigerator wall

7,8,9,10 ... the ball-and-seat Internal baffle

11 ... electronic timer

See also shown in Figure 1, the utility model mainly comprises blast pipe 1, axial flow blower 2, row, air inlet ball-and-

seat

3,4, air inlet pipe 5, electronic timer 11 main members such as grade are formed, air inlet ball-and-seat 3, exhaust ball-and-seat 4 is to be installed in refrigerator wall 6 (being good to be installed on the refrigerator rear wall generally) respectively separatedly by a distance, and this ball-and-seat 3, the 4th, be a kind of easy internal baffle formula ball-and-seat, at ball-and-seat 3, embed the oval middle deckle board that has slot in 4 the pipe, the minor axis of this ellipse deckle board is the level of state, above slot, hang with baffle plate (similar bamboo door curtain form), make it close the shutoff slot automatically to a direction unlatching and by self or counterweight, be that double-deck baffle plate 7 is set in the present embodiment, 8 and 9,10, its objective is for better air-isolation; The outside of this exhaust ball-and-seat 3 (promptly by the refrigerator wall outside) is connected with axial flow blower 2, and axial flow blower 2 other ends connect a blast pipe 1 straight-through atmosphere again; These air inlet ball-and-seat 4 other ends then directly connect air inlet pipe 5, above-mentioned axial flow blower 2 is to be connected with an electronic timer 11 that is sticked below this refrigerator wall 6, the commentaries on classics of the switch order Control Shaft flow fan 2 that sends by electronic timer 11 when refrigerator normally uses with stop and then the opening and close etc. of control row, air inlet ball-and-seat 3,4.The electrical schematic diagram of this electronic timer 11 sees also shown in Figure 2, is to be known technology, does not repeat them here.

Air inlet pipe 5 and condenser can be pressed close to during actual production, intake air temperature be descended and defrosting, can a plurality of air admission holes be set in refrigerator in addition so that carry out air exchange more equably.Certainly when practical application in this way for current refrigerator is transformed, for example transform voluntarily when installing the utility model additional in the family and then can save air inlet and exhaust piper, only, adopt so-called direct-type inlet and outlet mode with inlet and outlet ball-and-seat and axial flow blower.Earlier the punching of refrigerator rear wall is encapsulated in ball-and-seat wherein with glue again during installation, the connecting axle flow fan installs timer and gets final product, and the new product of production can be guided to air inlet and exhaust piper outdoor.

In sum, the utility model utilization is installed on the refrigerator wall and a pair ofly can be produced the device of inlet and outlet automatically, can realize air cleaning and fresh-keeping effect that refrigerator cold-storage is indoor, fundamentally solve the problem of refrigerator peculiar smell, inexpensive, but can receive good effect, have good industrial utilization.
