The technical field
The present invention relates to the design of the refrigeration apparatus, such as a household refrigerator or freezer.
The level of technology
When mounting such a device first from separate parts going insulating housing with hollow walls, running the wiring for the control electronics connection with various sensors, in particular sensors for measuring the temperature of the refrigerating chamber, for detecting opening of the door, and managed by the compressor, installed in the housing, connected to each other and are filled with the individual components of the refrigerant circuit, and a hollow casing wall filled with insulation foam. For this you need to carefully insulated holes in the walls, which is required for installation of the sensors, to prevent penetration of foam insulation through these holes. All these steps require significant installation labor costs, and due to the large diversity of these works to automate difficult and expensive.
Disclosure of inventions
The task of the invention is to propose a concept design of the refrigeration system, which will simplify the process of installation will reduce the number of stages that are directly associated with the Assembly of the device, and thereby may provide the th rational and more economical Assembly.
This problem is solved refrigerating apparatus with signs of paragraph 1 of the claims. When installing the electronic module in the cutout of the housing passages, which, if known construction must be done between the control unit and the refrigerating chamber of the refrigerator, are transferred to the electronic module, reducing the number of passes through the body itself, and therefore, it reduces the complexity of manufacturing the housing. In addition, the manufacture of the electronic module, the size of which is significantly smaller than the size of the refrigeration apparatus can be easily isolated in a separate proceeding, which may be cheaply and effectively implemented on a specialized enterprise for the production of electronics equipment.
To place a cut formed of heat-conductive channel, it is preferable that the electronic module was insulated similarly to the case.
A particularly simple construction is obtained if the electronic module must only be inserted into the body.
Preferably the cut-out must be done in the frame formed by the frame and hung on his door, and to have an open region, such as the neckline is easier to perform than the neckline, surrounded on all sides by the edges of the cutouts in the case.
Preferably, the electronic module is installed in the cutout direction is shining, so it can push and pull from the side of the open edge.
According to the first variant of implementation related to the housing outer side of the electronic module does not contain electrical connections, so that electric passages in the body, complicating its manufacture, can be discarded. In the simplest case, the control cable and/or power between the electronic module and accessible from outside the housing of the compressor can be routed around the outside of the housing. If, for example, for security reasons, to lay electrical cable to the electronic module around the outside of the body is impossible, on the electronic module and the housing can be provided by complementary half of the electrical connector. These connectors may be, in any case, less than the number of accessions to the conventional electronic Board for refrigerating apparatus; typically, only one pair of connectors.
Installation of the electronic module in the neckline allows on one hand to put the sensor for measuring the temperature in the chamber directly on the electronic module, so that the passages in the casing for connecting this sensor becomes unnecessary. On the other hand, you can also install the temperature sensor in the body and its signals to pass for processing electronic module cher the C e connector in the neck. Exactly the same can be embedded in the electronic module operational status indicator, for example, the measured temperature in the chamber or defective or normal state of the device.
A light source for lighting the camera can also be part of the electronic module. Required to turn on and off the light source switch-controlled door, it is also advisable to make part of the electronic module.
If the refrigeration apparatus is provided with a fan for air circulation in the chamber, it is also advisable to set on the electronic module. In General, we can say that the electronic module should be possible to concentrate all electrically operated components of the refrigeration apparatus.
The fan is provided in particular in the refrigeration apparatus of the type "No Frost", in which the evaporator is separated from the refrigerating chamber evaporator chamber, and a fan is needed to provide air circulation between the evaporator and the refrigerating chamber. In such apparatus it is advisable to make connecting passage for airflow between the cooling and evaporation chamber via electronic module.
In this apparatus further simplification of the installation is possible by placing the evaporation chamber in which is separated from the housing module of the refrigeration machine is us. This module refrigerating machines can also be manufactured in advance separately from the body, which in particular simplifies the filling and closing of the refrigerant circuit. The refrigerant pipes of the refrigeration module in this case may preferably be connected with refrigerant pipes in the housing with a sealing plug connectors.

The implementation of the invention
Depicted in figure 1 of the refrigeration apparatus is known from the housing 1 with globalteam plastic inner container 2, which limits the camera 3 for the storage of refrigerated products, and consisting at least partly of sheet metal outer wall 4, separated from the within the unit container 2 intermediate cavity, filled with insulating foam.
In the ceiling 6 of the housing 1 is formed a rectangular open front neckline 7. In this cut 7 from the front side retracts flush like compounds in the tongue and groove electronic module 8. Electronic module 8 has the form of a rectangular box whose dimensions correspond to the dimensions of the slots 7, and the upper and lower sides of the box expanded laterally, so that the speakers for the box dimensions of the ribs 9 limit stretching along the electronic module slots 10. When the electronic module 8 is pushed from the front side into the groove 7, the ribs 9 cover the longitudinal edges 11 of the recess 7 and, thus, on the one hand, form a support for the electronic module 8, and on the other hand, provide sealing of the refrigerating chamber 3. To improve the seal in the grooves 10 may be provided (not illustrated) elastic sealing gasket, which when the electronic module 8 is compressed between the housing and the longitudinal edges 11.
With this design of electrical wiring, which energizes the electronic module 8 and relays commands to the electronic module to the compressor in the refrigerant circuit of the refrigeration unit, passes from the compressor through the housing 1 to a plug socket 12 on the rear end of the recess 7. When the electronic module 8 STOVL who is in the notch 7, the grooves 10 slide along the longitudinal edges 11 and an electronic module 8 is in its prescribed mounting position at which its front side is set flush with the housing 1 located on the rear side of the electronic module 8 contact pins 13 are in the socket 12.
On the front side of the electronic module 8 is the button 14, which, if it is not pressed against the closed door 5, closes an electrical circuit located on the bottom side of the electronic module source 15 light for illumination of the refrigerating chamber.
Next to the button 14 is the indicator 16 operational status, which the user sees during each opening of the door 5 and which can be used for indicating the temperature measured is depicted in figure 2, also located in the electronic module 8 sensor 17 and the temperature of the refrigerating chamber, or simply to indicate defective or faulty condition of the refrigeration apparatus.
Electronic Board 19 is installed in the electronic module 8 near its front side and thermally insulated by insulating material at least on the part of the refrigerating chamber 3, and preferably also from the outside.
The controller 18 to set the desired temperature of the refrigerating chamber 3 can be installed depending on the availability of freedoms the CSOs also on the front panel or, as shown in figure 2, drawn to the refrigerating chamber 3 bottom side of the electronic module 8.
The temperature sensor 17 is located near the rear end of the electronic module 8. Due to its remoteness it is protected from the effects of heat emitted by a source 15 of the light of the refrigerating chamber.
Figure 3 shows the second embodiment of the proposed invention is the refrigeration apparatus, shown from the rear. The drawing is visible located in the rear recess of the housing 1 is connected by a cable 21 control and power electronic module 8 of the compressor 22. The cable 21 is held here on the back side of the housing 1, to which it may be suitably attached, for example, with glue, cable clamps, etc. It is attached to the open upper side of the electronic module 8, so that the electrical wires in the housing 1 does not require any cuts that would have to be sealed to fill the housing 1 foam.
The complete absence of electrical inputs through the body 1 makes this design suitable for the manufacture of the housing 1 of the vacuum insulation panel.
Figs.4 and 5 show the proposed invention refrigerator option "No Frost". The casing of this appliance consists of a container module 26 module 27 of the refrigerant circuit. Module 27 of the refrigerant circuit contains all the usual components to the tour of the refrigerant of the refrigerator, including the evaporator 28, and insulating the rear wall 29 and the sidewall 30. In the assembled refrigerator rear wall 29 of the sidewall 30 and the rear wall 31 of the container module limit the camera 32 of the evaporator, in which is placed the evaporator 28 and which through holes in the upper and lower part of the rear wall 31 is connected with the cooling chamber 3. The top of these holes 33 shown in section in figure 5; it goes horizontal section 34 of the pipeline in the container module 26, which is adjacent a corresponding portion 35 of the pipeline in the electronic module 8. In the downward final part of section 35 of the pipe 35 is the fan 36, the management and supply of electricity which is produced through the electronic module 8.
As shown in figure 5, the electronic Board 19 is only a small part of the volume of the electronic module 8, with the remaining volume filled with an insulating material 38, for example, as in the case of the housing 1, by filling foam material or by inserting a pre-formed pieces of insulating material. The control cable and power supply 21, which comes from the electronic circuit Board 19 to the compressor 22 (not shown in this drawing), divided into two pairs of connectors 39 into three parts, the middle of which passes through the section 34 of the pipeline, without passing quasiscience container module 26. Although the cable 21 with this design is protected and goes inside the refrigerating apparatus, the cable entry in the container module 26, which would require sealing is not needed.
