Description

A kind of refrigerator of preserving moisture

Technical field

The utility model relates to refrigerator, more particularly, relates to a kind of refrigerator that humidity keeps function that has.

Background technology

The condensate moisture of general refrigerator air in when refrigeration usually can be with refrigerator, freeze; thereby the humidity in the reduction refrigerator; cause the interior humidity of case usually at 30%～40%; and the relative humidity of the best of fruits and vegetables and meat storage is 80%～90%; as peach be 83%, pork is 85%～90% etc.; so just cause fruits and vegetables and meat to occur air-dry phenomenon easily, lose the quality of original delicate flavour at the general refrigerator storage.And along with China's trend of urbanization and raising of resident living level gradually, people require refrigerator will have extraordinary fresh-keeping function, just can become the good assistant of household culinary art, to adapt to allegro life.Have good fresh-keeping effect, the humidity in the refrigerator must remain on best storage humidity, could solve the defective that general refrigerator exists air-dry fruits and vegetables and meat.But temporarily also there is not the constant refrigerator of a kind of humidity to sell in the market.

The utility model content

The technical problems to be solved in the utility model is, a kind of refrigerator with moisture-keeping functions is provided, make the indoor maintenance storage of cold compartment of refrigerator or fruit and vegetable vegetables suitable humidity, to overcome the deficiencies in the prior art.

For solving the problems of the technologies described above, construct a kind of refrigerator of preserving moisture, comprise refrigerator body, refrigerator refrigeration system, cpu controller, also comprise the humidity sensor, the housing with water inlet and steam drain, the built-in humidifier of described housing that are arranged in the refrigerator body, described humidifier and humidity sensor are electrically connected with described controller.

In the above-mentioned refrigerator of preserving moisture, described humidifier comprises in order to the heater that the water that stores in the described housing is heated into water vapour, in order to water vapour is forced to be sent to the fan of described steam drain.

In the above-mentioned refrigerator of preserving moisture, the built-in liquid level sensor of described housing, described liquid level sensor is connected with described controller.

In the above-mentioned refrigerator of preserving moisture, described housing sidepiece is provided with discharge outlet.

In the above-mentioned refrigerator of preserving moisture, described housing be arranged in the refrigerating chamber or the fruit and vegetable district of refrigerating chamber in.

In the above-mentioned refrigerator of preserving moisture, described housing is arranged in the freezer compressor storehouse, and the dehumidification tube that is communicated with refrigerating chamber is set on the described steam drain.

In the above-mentioned refrigerator of preserving moisture, the condenser portion pipeline section of described refrigeration system passes described housing and is immersed in the interior water of housing.

The utility model compared with prior art has the following advantages and beneficial effect:

1. the work of humidifier is controlled by refrigerator controller, and refrigerating chamber or fruit and vegetable chamber humidity can be kept within the specific limits, is beneficial to the storage of fruits and vegetables.

2. simple in structure, realize easily on the technology.

3. the humidification user does not need manual operation, the convenient use.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment one

As shown in Figure 1, place the controller 108 of band cpu central processing unit at refrigerator body back top, controller 108 has a plurality of inputs, output port, is connected with components and parts such as operation display, door switch, refrigerating chamber illuminating lamp, compressor on the door body respectively.Refrigerator refrigeration system mainly comprises compressor, condenser, capillary, the evaporimeter that is linked in sequence, and compressor only is shown among Fig. 1.Establish the housing 103 of humidifier install one in the compressor bin of placing compressor in, housing 103 has water inlet and steam drain 109, and housing 103 bottoms are filled with water, and humidifier is by forming at the heater 101 of housing 103 bottoms with at the fan 104 on housing 103 tops.It above fan 104 steam drain 109, with dehumidification tube 106 steam drain 109 is connected with refrigerating chamber again, (perhaps in the fruit and vegetable district) is equipped with a humidity sensor 107 at freezer wall, humidity in humidity sensor 107 vasculums, humidity sensor links to each other with controller and sends humidity data to cpu central processing unit, the work of CPU humidity data control humidifier.Its course of work is as follows: when refrigerator in when refrigeration, humidity in the refrigerating box descends, at this moment, the data that the humidity sensor of refrigerating box will collect humidity in the case pass on the refrigerator controller, controller calculates and compares with the humidity of setting that (humidity of setting presets before can dispatching from the factory, or set by the operation display on the door body) by the user, if when being lower than the humidity of setting, controller sends control signal and makes heater 101 heating, fan 104 starts, heater heats the twitch of the water vapour of generation by fan in water like this, enters in the refrigerating chamber (fruit and vegetable district) through dehumidification tube 106, and its humidity is raise.When humidity had arrived setting value, controller sends control signal made heater stop heating and fan outage, stops humidification.By such humidification control, the humidity in the case is maintained in the best scope.Not enough for preventing the water yield in the housing, one liquid level sensor 102 is set in housing 103, when the water level in the housing 103 drops to certain position, liquid level sensor 102 low level conductings also are sent to controller with information, controller output control signal is given buzzer warning, and the power supply of cut-out heater 101, stop heating.When the user added dilutional hyponatremia, liquid level sensor 102 high-order conductings also were sent to controller, and controller is also exported control signal and given buzzer warning, tells the user to add dilutional hyponatremia, and this moment, too much water flowed out from discharge outlet 110.Fig. 2 illustrates the topology layout of humidifier, and housing 103 has water inlet and steam drain 109, and heater 101 places housing bottom, and the 102nd, liquid level sensor, fan 104 be on the top of housing, and below the steam drain 109, discharge outlet 110 is about 2/3 place highly of housing.Fig. 3 is the electrical equipment control theory diagram of humidifier in the utility model, controller 108 has cpu central processing unit, liquid level sensor 102 links to each other with the input port of controller with humidity sensor 107, heater 101, fan 104, alarm 201 are connected the output of controller, control its work by controller.

Embodiment two

As another kind of embodiment of the present utility model, the humidifier parts are placed on the inside, fruit and vegetable district of refrigerating chamber or refrigerating chamber, add the water vapour that hot water produces by heater 101 and directly drain into refrigerating chamber (fruit and vegetable district) from steam drain, the dehumidification tube 106 in order to steam drain 109 is connected with refrigerating chamber shown in Figure 1 can be cancelled.The structure of other control method as humidifier 101 work, housing 103 inside is identical with such scheme, no longer describes in detail.

Embodiment three

In refrigerator refrigeration system, the high-temperature high-pressure refrigerant that comes out from compressor cools off condenser, therefore the temperature of condenser pipe is higher relatively, if the water in a part of heat transferred housing of condenser, then can reduce the working time of heater 101, save electric energy, improved the efficient of condenser simultaneously.For this reason, on the basis of embodiment one, one section condensation pipeline section that will be connected with compressor outlet inserts the water that passes and be immersed in the housing from the top of housing 103, forms a U-bend, during compressor operating, the water in the housing is heated.
