Description

Cooling and hot water supply device for hot and cold water purifier using thermoelectric element{Heating and Cooling Supply System for Sleeping Bag}

The present invention relates to a cold/hot water supply device for a cold/hot water purifier using a thermoelectric element, and more particularly, a cold/hot water supply for a cold/hot water purifier using a thermoelectric element capable of producing and supplying high-efficiency hot water in a short time even at a poor sub-zero temperature. It relates to the device.

In general, a water purifier is a device that purifies raw water using a filter or a membrane, stores it in a storage container, and takes in water that has been purified and stored in a storage container so that it can be safely consumed.

As water purifiers for supplying water of various temperatures, there are water purifiers that can take room-temperature water (purified water) and cold water, and cold-and-hot water purifiers that can intake purified water, cold water, and hot water.

The cold/hot water purifier passes through a filter unit composed of a plurality of filters and cools the purified water with a cooling means and stores it in a storage container, or heats it with a heating means and stores it in a storage container. to provide.

As described above, a general cold/hot water purifier is provided with a separate storage container to store cold water and hot water.

For example, Korean Patent Laid-Open Publication No. 10-2011-0008627 discloses a cold water purifier. In this cold water purifier, a water purification tank for storing purified water filtered by a filter for filtering incoming raw water, the purified water tank and A cold water tank connected by a connection pipe and receiving purified water from the water purification tank by a natural water pressure difference with the water purification tank through the connection pipe is provided.

In addition, Korean Patent Laid-Open No. 10-2013-0141200 discloses a cold/hot water purifier or a cold/hot water dispenser capable of discharging hot water in a short period of time.In this cold/hot water purifier or a cold/hot water dispenser, water can be stored inside, and the ceiling A hot water tank having a predetermined slope with the surface of the water and having an air vent formed at the highest part of the ceiling is provided.

However, since such a conventional cold and hot water purifier inevitably uses both a storage container for storing cold water and hot water, that is, a cold water tank and a hot water tank, the overall volume increases.

In addition, the use of cold water tanks and hot water tanks causes cost increases because pumps and water level control sensors are provided, and unnecessary energy (power) is required because it is necessary to maintain a high-temperature hot water state at all times to provide hot water. There was a wasted problem.

In order to solve this problem, domestic registration number 10-1668017 (registration date October 14, 2016) allows the water flowing through the coil-type water pipe to be cooled and heated instantaneously using a heat transfer conductor block and a thermoelectric element. By supplying cold and hot water, it is not necessary to have a storage container for cold and hot water and a pump accordingly, so it is possible to reduce the manufacturing cost while miniaturizing the volume, and because there is no need to maintain hot hot water at a high temperature, unnecessary waste of energy (power) is reduced. An instantaneous hot and cold water device of a water purifier is described.

However, the instantaneous cold and hot water device of such a water purifier has a limitation in producing and supplying high-efficiency hot water in a short time even at poor sub-zero temperatures while using a number of thermoelectric elements.

In addition, in order to configure a conventional cold/hot water purifier, since a compressor is required for cold water production and a heater is required for hot water production, the configuration of the entire cold/hot water purifier is complicated, and thus, it is difficult to design a compact cold/hot water purifier.

Domestic Publication No. 10-2011-0008627 (published on January 27, 2011) Domestic Publication No. 10-2013-0141200 (published on December 26, 2013) Domestic registration number 10-1668017 (registration date October 14, 2016)

When the ambient temperature of the water purifier is an image, the temperature of the reaction surface S1 of the thermoelectric element 133 is controlled to be relatively 2 to 3° C. lower than the ambient temperature of the water purifier so that heat absorption is smooth, and the water purifier When the ambient temperature is below zero, the ambient temperature of the water purifier is ignored, and a temperature difference is controlled so that condensation or condensation of water vapor does not occur on the reaction surface S1 of the thermoelectric device 133. Cold and hot water supply device of used cold and hot water purifier
